Description

200925421 . IX. INSTRUCTIONS: TECHNICAL FIELD OF THE INVENTION The present invention relates to an air compressor. [Prior Art] In general, in an air compressor, a compression cylinder that slidably receives a compression piston is mounted on a side of a crank case. In the casing, the rotary shaft is rotatably set. A connecting rod (c〇n r〇d ) is mounted to the above-mentioned rotary shaft via an eccentric plate. The front end of the link is coupled to a compression piston in the compression cylinder. The eccentric plate is retracted by the motor and the rotary shaft. The compression piston coupled to the connecting rod is reciprocated within the compression cylinder. Thereby, the air introduced into the compression cylinder is compressed. The compressed compressed air system is sent to the air tank and stored via a connecting pipe connecting the compressor and the air tank (refer to Patent Document 1). [Patent Document 1] Japanese Laid-Open Patent Publication No. 2006-188954 φ Further, in the case of combining a compressor body including a motor and a compressor and a peripheral device including an air tank, in order to prevent the sound from being transmitted from the compressor body to the air groove due to vibration, the noise is increased or In the event of a machine failure such as a pressure gauge, the cushioning material is disposed between the compressor body and the peripheral machine. Further, a connecting pipe for supplying compressed air from the compressor to the air tank is also connected to the compressor at one end and to the air tank at the other end. Therefore, the connection pipe system is also fixed to the compressor or the air tank via the buffer material at the road portion. In addition, since the compressed air in the compressor becomes high temperature due to the heat of compression, the air density is low, and if it is sent to the air tank in this state, it is cooled by 7042-9855-PF; Tungming 5 200925421, and decompressed for a long time. In operation, the internal pressure of the air tank does not rise, and the efficiency is not good. There is a need to cool the compression heat in the pipeline that carries the compressed air, and then guide it to the air tank after the & Therefore, the conveying pipe of the compressed air has to be extended. Further, since the vibration system of the compressor and the air tank is greatly different, the connecting pipe connecting the compressor and the wire groove is, for example, even supported by the cushioning material.

The composition of the 'resonance' is caused by a large difference in vibration, which is caused by damage or breakage and becomes a major cause of air leakage. In order to prevent such vibration transmission and to improve damage, it is preferable to use a flexible tube excellent in flexibility because of the flexibility of the fixing portion. Since such piping materials are required to be high temperature and high pressure, the conventional substrate uses a flexible tube composed of stainless steel (SUS) or Teflon (registered trademark) material. However, the flexible tube which uses SUS or Teflon (registered trademark) material as a substrate has a high price, and if the piping is long, the price is higher. A first object of the present invention is to provide a movable type compressor that can reliably cool a connecting pipe that is sent from a compressor to an air tank. Generally speaking, 'the air compressor system for construction, along with the construction work, it is necessary to move from one place to another, and in order to prevent being stolen, it is necessary to take it back every day. place. Therefore, the air compressor can be moved. That is, the air compressor is desirable for small size and light weight. Further, the air compressor is as described above, and the compressor body of the compressed air and the air tank for storing the dust-reduced air are mainly used as the main structure 7042- 9855-PF; Tungming 6 200925421 In terms of the main body of the machine, a machine is hot, so it is not only necessary to break the + piece in order to release it. p & A, cooling hair, cold parts means must also be equipped. Therefore, in Patent Documents 2 and 3, the rotary fan and the sir_fan are compressed by the front and rear of the main body by the two. The two cooling fans forcibly make the air compressor, and the heat generating components are cooled. In addition, due to the evolution of the construction method: = and etc., continuous operation is required, and high-pressure air must be stored in a large amount; the compressed air is slowly discharged in a large amount. It is also stored in the air, [Patent Document 2] 曰本特开平u_218〇 〇 专利 专利 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 62 如 如 62 62 如It is troublesome to carry. The second problem of the present invention is that the cooling fan can efficiently cool the motor or the waste reduction machine by omitting a conventional multi-blade fan, thereby providing miniaturization. Or a lightweight air compressor. Also, because the construction site is an environment that is prone to dust, the air used for construction at such sites is used for dust prevention. Cover cover. Also 'construction air is shrinking machine, because in the compression operation, the parts vibrate and the noise occurs, or - part of the parts are heated, not only for dust prevention, because of the necessity of safety or noise reduction, cover (c〇 Vering) is applied. In general, the cover ((:.) is used in (4) machine body or air tank. 7042-9855-PF; Tungming 7 200925421 Compressor This system is integrated with the compressor as a vibration source In addition, since the air channel is a part that is transmitted by vibration, a large resonance occurs by fixing the cover at a portion where the amplitude or direction of the vibration is different. To prevent this, the cover is fixed by a plurality of screws. In addition, the cover is only fixed to the 蓊 匕 匕 匕 匕 ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 If the cover is fixed to the retractor body or the air slot by a plurality of screws, the vibration of the compressor body and the vibration of the air groove are directly transmitted to the cover '(4) sound function loss, but the noise is increased. Problem occurs A third object of the present invention is to provide a portable air compressor which is reduced in noise by a structure in which vibration is not transmitted to a cover, and X can be decomposed by assembling the t or the material by reducing the fixing place of the cover. The work is easy to use and the weight is reduced. Also, the use environment of the building air compressor is sometimes used as a building site outside the house. Because the dust is easy to occur when the building site is processed, the compressor system is covered by a cover. Further, in a small-sized air compressor, a measuring instrument such as a pressure gauge or a pressure reducing valve that is frequently operated or visually confirmed, etc., is often disposed above (refer to Patent Document 5). The upper opening, from which the measuring instrument is exposed. Especially since the pressure gauge is fragile to the impact and the pressure gauge is frequently contacted with the cover, the hole may cause the pressure gauge to be broken or become incorrect, so the hole and pressure in the cover There is a need to set a gap (Cl earance) between the meters. This gap is 7042-9855-PF; Tungming 8 200925421 must be the cumulative tolerance of the parts of the pressure gauge. Therefore, the installation position of the pressure gauge is used as the screw pitch portion. ^ = Even if the position is adjusted by screwing, the gap has to be expanded: between the hole of the cover and the pressure gauge. Patent Document 5] Japanese Special Opening 2_-1 12388 ... 丨 In the structure of knowing, because the gap between the hole of the cover and the pressure measuring instrument is large, the Gelu 60 heavy instrument dust valley is easy to enter from the gap, and there is noise leakage.

问题 Problems that leak to the outside. A fourth object of the present invention is to provide an air compressor which reliably prevents dust from entering the inner lid of the lid, and which is also preferable in appearance. Further, as described above, the mobility of the air compressor is emphasized as being small and lightweight. At the time of handling the air compressor, not only air compressors, but also many other props are transported. In order to carry it efficiently, the operator would like to move as many items as possible with the air compressor. Therefore, there is a shoulderbelt detachable air a reduction machine. When carrying, use: With the air compressor hanging on the shoulder, the two hands are free to hold: he props. In other words, such an air compressor side is provided with a hanging member, and when the compression operation is performed, the shoulder strap is removed, and when it is conveyed, it is suspended. However, with the hanging member system and the importance of safety, the cost of the product rises because of the strong structure. In addition, when the cost is increased, the belt-mounting portion can be formed in a part of the synthetic resin member. The belt mounting portion is damaged during transportation, and the air compressor of the shoulder is dropped and damaged. The problem that caused the accident. 7〇42-9855-PF; Tungxning 9 200925421 • A fifth object of the present invention is to provide a portable air compressor which can simultaneously realize the safety and low cost of the hanging member of the shoulder t. SUMMARY OF THE INVENTION In order to solve the above first problem, the first aspect of the present invention includes a secondary compressor that compresses compressed air compressed by a secondary compressor and compressed by a two-two compressor. One end of the casing on both sides is provided with a compressor 纟胄 of the motor, and an air compressor disposed in an air tank of the compressor body, and the secondary compressor and the air tank system are provided by a high exothermic tube and The connecting pipe formed by the flexible pipe is connected, and the end of the high heat radiating pipe is connected to the secondary compressor, and the end of the flexible pipe is connected to the air tank. In the air compressor according to the first aspect described above, the secondary compressor and the air tank are connected via a connecting pipe formed by connecting the high heat releasing tube and the flexible tube, and since the end portion of the highly exothermic tube is connected In the above-described secondary compression φ machine, the end portion of the flexible tube is connected to the air groove. Since both ends of the high heat release tube are provided in the compressor body, the vibration in the same direction is received and the deformation is small. Moreover, the flexible tube absorbs vibrations in different directions. Further, since the length of the connection pipe is half that of the entire pipe, the cost can be lowered. Therefore, the occurrence of resonance can be effectively prevented. Further, since the highly exothermic tube is excellent in thermal conductivity, it is easily cooled by contact with the outside air, and the compressed air having a high temperature in the high exothermic tube is efficiently cooled and sent to the air tank. According to a second aspect of the present invention, in the first aspect of the air of 7042-9855-PF; Tungming 10 200925421, the connecting portion between the high heat releasing tube and the flexible tube is fixed via a cushioning material. On the compressor body. In the air compressor according to the second aspect, the connection portion between the high heat release tube and the flexible tube is fixed to the compressor main body via the cushioning material, and the highly exothermic tube is subjected to the end portion on the compressor side. Vibration in the same direction, and the vibration of the compressor body is absorbed by the cushioning material, and will not be directly smashed

The ground propagates to the end of the flexible tube and the joint side. Therefore, damage due to vibration or the like is effectively prevented. According to a third aspect of the present invention, in the air-muffler of the first or second aspect, the flexible pipe system is disposed in a direction different from a vibration direction of the compressor. You Gong Gongdi three views, frankly the flexible pipe system is set in a direction different from the vibration direction of the compressor, because (4) can be stretched in the longitudinal direction, the force is not so it can absorb shock better 'And damage or deformation is not easy to occur. Therefore, durable. According to a fourth aspect of the present invention, in any one of the first to the above air compressors, the sister and the gentleman recognize that the heat transfer tube and the flexible tube are connected: the connection: As a plurality of tubes are sealed through the joint '°, and the above-mentioned joints are respectively formed by the η &# π & - joint portion and the second switch, and the first Φ ^ ^ β (4) of the spherical concave surface formed at the end of the first joint 将 is inserted and held in a second rotation. The end phase-defining range can be in the air pressure exothermic tube and τ## of the fourth aspect of the present invention, because instead of the high-drawing tube, the "manufactured (four), the material take-over as the re-entry 7〇42-9855 - PF;Tungm.ng n 200925421 The first joint portion and the second joint portion which are formed by the joints of the joints and the joints which are connected by the joints The inner side of the spherical concave portion of the end portion of the first joint portion is rotatably inserted and held at an end portion of the second joint portion in a predetermined range, and the two joint portions are in all directions except for the expansion and contraction direction. In addition, since the system of the retracting machine does not vibrate in the front-rear direction, the vibration of the compressor can be effectively absorbed. In order to solve the above second problem, according to the fifth aspect of the present invention, the casing having the compressor is provided. One end of the motor is provided with a compressor main body, an air tank disposed in the compressor main body, and an air compressor that covers the cover of the compressor main body.

In the air compressor according to the fifth aspect of the invention, the cooling fan is disposed at the motor-side end of the compressor body, and the end portion of the motor on the cooling fan side is provided. 'A wind deflecting disc that is disposed at the center opening and whose funnel is opened at the end, and the cooling air from the cooling fan is shunted by the wind deflecting disc to the internal cooling air guided to the inside of the motor, and from the outside of the wind deflecting disc The external cooling air that is guided to the outside of the motor 'in the upper and lower portions of the casing side, respectively, forms a row 70 for discharging the internal cooling air. 42-9855-PF; Tungming 12 200925421 Air hole, and external cooling air is guided to the motor (4) air intake hole, and because the cooling air blown by the cold part fan is guided by the air guide circular plate, the internal cooling air is guided. (4) of the cooling motor, the external cooling air system on the outer side of the air guiding disc becomes a cold portion from the intake hole of the τ• portion of the motor housing to the upper portion, so that the compressor and the motor can be provided. It is cooled efficiently. In addition, when the external cold part wind flows along the inner surface of the cover, its speed is the fastest, because during operation, the compressor that becomes the most temperature is guided by the high speed along the inner surface of the cover. Since the cooling air is cooled, it is cooled efficiently. Therefore, since the compressor body can be cooled only by the cold fan, the conventional multi-blade fan can be omitted. Thereby, the air compressor can be greatly miniaturized. And lightweight. According to a sixth aspect of the present invention, in the air compressor of the fifth aspect, the first air deflector that guides the external cooling air to the lower air intake hole of the motor and the guide in the lower portion of the motor A second air deflector leading to the compressor is provided, and the second air deflector is formed by erecting the rear portion so that the external cooling air is transferred from the lower side of the compressor to the upper side of the crucible. In the air compressor of the above sixth aspect, the first air deflector that guides the external cooling air to the lower air intake hole of the motor and the second air deflector that is guided to the compressor are The second air deflector is formed by erecting the rear portion in such a manner that the external cooling air is turned from the lower portion of the compressor to the upper portion of the inner side, and the cooling air is guided to the heat due to the compression by the first air deflector. It is cooled by a compressor that is easy to generate heat, and because the cooling air is not only brought into contact with the compressor but is 'concently guided to its lower side and the inner side', the cooling effect is very good as the cooling air is large due to the large amount of air that the cooling air contacts the tube. 9855-PF; Tungming 13 200925421 • Still. According to a seventh aspect of the present invention, in the air compressor of the fifth or sixth aspect, the mounting plate of the current transformer that controls the rotation of the motor is horizontally disposed below the compressor main body, A gap in which a part of the external cooling air flows in between the lower end of the first wind deflector and the mounting plate is formed. In the air compressor of the seventh aspect above, because in the compressor body

Below the Φ, a mounting plate of the converter that controls the rotation of the motor is horizontally disposed, and a gap into which a part of the external cooling air flows is formed between the lower end of the first wind deflector and the mounting plate. In order to efficiently cool the converter. According to an eighth aspect of the present invention, in the air compressor of any of the fifth to seventh aspects, the air deflecting circular plate is a flat small circle of h fixed to an end of the motor. The plate and the wind guide disk body disposed around the plate, and the connection U' between the small circular plate and the wind guide disk body is disposed to block the ventilation between the coils formed on the motor The location of the space. According to the air compressor of the eighth aspect, the wind guide disk is composed of a flat plate-shaped small circular plate fixed to the center of the end portion of the motor and a wind guide disk body disposed around the air guide disk; The connecting piece system disposed between the small circular plate and the wind deflecting plate body is placed in the position of the ventilation space between the coils formed by the motor, and is guided by the air guiding circular plate body. An internal cooling air system between the coils can pass along the venting space. Therefore, by continuously feeding fresh cooling air continuously, it is preferable to cool the coil by 7042-9855-PF; Tungming 14 200925421. According to the ninth aspect of the present invention, iAAkAn, in any of the fifth to eighth aspects of the air compressor, the -second contraction 压 ^ pressure 'mechanism, by compressing the atmosphere / machine, and The first tube connecting the two refiners and the second tube connecting the secondary compressor and the air tank are configured by the above-mentioned magic machine, which is composed of a compression compressor compressed by a secondary compressor. The upper portion of the main body of the compressor is disposed on a side close to the cooling fan, and the two tubes are piped in a state in which the flow of the cooling air is different. In the air compressor of the ninth aspect, the compressor system is composed of a primary compressor and a secondary compressor, and the first pipe connecting the two compressors and the second pipe connecting the secondary compressor and the air tank The pipe is disposed in an upper portion of the compressor body, and the second pipe is disposed on a side close to the cooling fan, and the first pipe and the second pipe are piped in a state in which the flow of the cooling air is different in stages. The system is easily exposed to the cooling air. Therefore, the piping can also be cooled efficiently. According to a tenth aspect of the invention, in the air compressor of any one of the fifth to ninth aspects, the air intake hole of the cover is formed on a side surface corresponding to the cooling fan and located in front of the cooling fan The front 'exhaust hole system is arranged on the downstream side of the compressor. In the air compressor of the above-described tenth aspect, the intake hole of the cover is formed on the side surface corresponding to the cooling fan and the front side of the cooling fan is disposed on the downstream side of the compressor. Since the flow from the intake of the cooling air to the exhaust gas is smooth, the cooling air can be used for cooling without being trapped in a part. 7042-9855-PF; Tungming 15 200925421 According to a tenth aspect (fourth) of the present invention, in any one of the fifth to the above-mentioned air (four) machines, between the inner side surface of the cover and the compressor A cooling duct that flows along the inner surface of the cover and that is guided by the compressor, and a wind deflector that flows to the above-described tube with external cooling air are formed. In the air compressor according to the eleventh aspect, the cooling air of the material portion flows along the inner surface of the cover between the inner surface of the cover and the compressor, and passes through the crucible.

The air passage guided by the compressor is formed. When the external cooling air flows along the inner surface of the cover, the speed is the fastest. The compressor that is the highest temperature during operation is operated along the inner surface of the cover. The guided high-speed cooling air is cooled, so it is cooled efficiently. Further, the tube is efficiently cooled by forming the air deflector. Further, in order to solve the above-described third problem, according to the twelfth aspect of the present invention, a compressor main body including a motor provided at one end of a casing including a compressor, an air tank disposed in the compressor main body, and a cover compression are provided. In the movable air compressor of the cover of the machine body, the attachment piece is protruded and formed on one of the front, rear, and left and right sides of the cover, and at least one of the compressor main body and the air groove is provided corresponding to the cover mounting groove of the attachment piece. Forming, the women's wear piece is inserted into the cover mounting groove via the first cushioning material, and the cover is screwed and fixed to the cover mounting portion provided at least on the other of the compressor main body and the air groove via the second cushioning material. In the air compressor according to the twelfth aspect, the mounting piece is formed to be formed on the front and rear or the left and right sides of the cover, at least in either the compressor body and the air groove, and the cover mounting groove corresponding to the mounting piece is formed. , 7042-9855-PF; Tungming 16 200925421 * Description: The mounting is inserted into the cover mounting groove via the first cushioning material, because the cover is passed through the second The material is screwed and fixed to the cover mounting portion provided at least on the other of the above-mentioned collapsing machine body and the air groove, and the vibration on the main body side of the retractor is absorbed in the first cushioning material and the second cushioning material, and is not transmitted to the cover. Therefore, even if the body of the shrinking machine and the air tank vibrate differently, because the resonance will not be able to reduce the noise, this can surely achieve the effect of the queen and the partition that was originally expected. The fixing place of the cover allows easy assembly work or disassembly work during maintenance. Moreover, since the cover does not have to cover the entire air groove, the weight is also reduced. According to the thirteenth aspect of the present invention, in the twelfth aspect In the air compressor, an insertion portion into which the cover mounting groove is inserted in the horizontal direction is formed in one end of the first cushioning material, and the insertion groove inserted into the mounting piece of the cover is inserted in the other end. The portion is formed on the upper surface and the bottom surface of the insertion groove, and the plurality of protrusions that are in contact with each other at the above-mentioned women's wear piece are arranged in parallel at a certain interval in the left-right direction. In the air compressor of the thirteenth aspect, in the air compressor of the thirteenth aspect, the cover mounting groove is inserted in the horizontal direction at one end of the first cushioning material. The insertion portion is formed, and at the other end, the insertion groove of the attachment piece inserted into the cover is formed on the upper surface and the bottom surface of the insertion groove, and is spaced apart from each other at a predetermined interval in the left-right direction. The ridges are formed in parallel, and under the inserted portion, protrusions are formed at positions between the ridges. The direction of vibration of the compressor body is mainly in the vertical direction or 7042-9855-PF; Tungming 17 200925421 ==Cloud Because the insertion channel is formed in the horizontal direction, the water of the mounting piece and the vibration of the moving system absorbed by the insertion groove are absorbed by the protrusions on the upper and lower surfaces of the vertical groove of the women's piece. , and, underneath the ', because the protrusion is formed between the above-mentioned ridges, the meat portion of the groove bottom of the insertion groove is promoted to the deformation between the ridges and the protrusions, and the vibration is promoted. Absorption coefficient effectively, vibrations will not be communicated to cover.

In the air compressor according to the twelfth or thirteenth aspect, the second cushioning material has a screw insertion hole through which a screw fixed to the cover attaching portion is inserted. And a fitting groove fitted to the inner edge of the hole formed in the cover. In the air compressor according to the fourteenth aspect, the second cushioning material is a screw insertion hole through which the screw that is fixed to the lid attachment portion is inserted, and a hole that is formed in the hole formed in the cover. The fitting groove of the inner edge, the vibration of the screw

The movement is absorbed by the annular cushioning material, and the vibration of the screw is not transmitted in the cover.

In the bushing, a fitting groove that is closely fitted to the inner edge of the hole of the cover, and a fitting hole that is closely fitted to the pressure gauge are provided, and a portion between the fitting groove and the fitting hole is absorbed. The degree of vibration transmitted from the compressor body is as soft as possible. Therefore, it is possible to surely prevent dust generated at the construction site or the like from entering the inside from the gap between the cover and the pressure gauge. Also 'because the cover and the bushing can be easily moved or deformed relative to each other in the direction of the gap', the vibration transmitted from the compressor or the motor can be efficiently absorbed. "And, when viewed from the outside, because the center of the hole of the pressure gauge and the cover It becomes the same appearance 'and' the bushing is the edge-like appearance of the pressure gauge, so the appearance is improved. According to a sixteenth aspect of the present invention, a compressor main body including a motor provided at one end of a casing including a compressor, an air tank disposed in the compressor main body, and an air compressor covering a cover of the compressor main body are provided In the above-mentioned cover, a hole for a pressure gauge penetrating through the air groove side is formed, and a soft bush is mounted between the hole and the pressure gauge, and the bush is in the hole of the cover.

In the air compressor according to the sixteenth aspect, in the bushing, since the fitting groove is formed in the inner edge of the cover so as to absorb the vibration transmitted from the compressor, the fitting groove may be formed. Efficiently absorbed from 7042-9855-PF; Tungming 19 200925421 • ι or motor-transmitted vibration. Moreover, according to the above configuration, the same dustproof and appearance improving effect as that of the fifteenth aspect can be obtained.

In the movable air compressor of the cover of the main body of the compressor, the handle frame is erected: the left and right sides of the synthetic resin Φ 胄 handle disposed at both ends of the longitudinal direction of the compressor main body, and the intermediate rod is provided to the handles Between the frames, a lower portion of the metal tape-hanging member having a width that is accommodated between the handle frames enters the compressor main body side from a space below the intervening rod, and is engaged with the lower end portion of the tape hanging member. In a state in which the lower end portion of the compressor body side of the handle is engaged with the groove, the opening of the engagement groove is abutted against a mounting bracket fixed to the compressor body, and the handle is fixed to the mounting bracket.

In the air-reduction machine of the seventeenth aspect, the handle frame is erected in the middle of the left and right sides of the synthetic resin grip handle disposed at both ends of the longitudinal direction of the press-fitted MI to the thin body The rod is disposed between the handle frames, and a lower portion of the metal belt hanging member having a width that is accommodated between the handle frames enters the I reducer body side from the lower space of the intermediate rod, and is at a lower end portion of the (4) member. The opening of the engaging groove is abutted against the fixing groove formed in the engaging groove of the lower portion of the compressor main body side of the handle; the mounting bracket of the compressor body is fixed to the handle The mounting bracket can be used to secure the strap member while the handle is fixed to the mounting bracket. Since the hanging member can be fixed without using bolts or the like, it can be pressed at a low cost. And 'because the snap groove can be blocked by the 7042-9855-PF even if it is up or in the horizontal direction; Tungmin. 20 200925421 The mounting bracket is blocked, & |V + 1 plug so in the due to the hanging member from the card, + Face, must be for the An F #加amine t +1 < 卞口沟脱方 Today's women's 托木洛洛 or 卡合沟 is destroyed, 任—十. This can achieve both security and low cost. According to an eighteenth aspect of the present invention, in the upper air retractor, in the handle, the engaging groove is formed to be raised to a joint portion of the engaging member. In the air squeezing machine of the above-mentioned eighteenth aspect, the card is at the lower end of the card, and the upper part of the engaging groove is raised to the upper end of the card at the lower end of the card. The joint is formed. Therefore, for example, in the air-to-air (4) reduction machine, even if the engagement groove is broken by the engagement groove of the handle or the like, the air (four) machine is dropped, and the belt hanging member is relatively raised to the upper side with respect to the empty machine. The lower end of the belt-hanging member is engaged with the air-reducing machine, the two-two member=hanging and being stretched in the rod-shaped portion as the middle, and the L=the member is rotating the handle, and the end portion is pressed to the above-mentioned engaging portion. — #件不出出出. Therefore, 'there is a stop on the way by the air compressor, and the accident is avoided. The safety of the higher layer is ensured.

Damage or accident is avoided. Therefore, the safety is extremely high. Other features and effects will be apparent from the description of the embodiments and the appended claims. [Embodiment] (Outline of Portable Air Compressor) As a typical embodiment of the present invention, the present invention will be described with respect to a case where a movable air compressor which is applied to an example of a pneumatic compressor is used. In the first and second figures, the symbol A indicates a portable air compressor. This air fortification machine A system includes: a reduction machine body 5, and a motor 4 is provided in the machine E 3 having the left and right retracting machines 2 shown in FIGS. 3 and 4; The grooves 6 are disposed at the lower left and right sides of the compressor body 5, and the cover 7 covers the compressor body 5. Further, the 1" is an operation panel '101 is an extraction port for compressed air. The two compressor systems disposed on the left and right outer sides of the casing 3 are the primary compressor 1 and the secondary compressor 2, and the high-pressure pressure 7042-9855-PF is produced by two-stage compression; Tungmin. 22 200925421 . It is composed as usual. As shown in Fig. 8, the motor case 8 is integrally formed at the end portion of the front side of the casing 3, and the motor 4 is disposed in the motor case 8. The motor 4 is a DC brushless motor that rotates the rotary shaft 12 by an electromagnetic force acting between the rotor 1 and the stator U, and is driven by the converter control. The stator u is constituted by a stator coil or the like, and is a mode in which the rotor 1〇 is surrounded from the outer circumference side. The rotor 10 is composed of a permanent magnet or the like and is integrally provided to the rotary shaft 12. The rotary shaft 12 is extended in the casing 3. The bearings 13 respectively disposed on the side of the motor 4 on the side of the casing 3 and the center of the toilet cover j 8 are rotatably supported. The rotary shaft 12 is extended in the inside of the casing 3. In the casing 3, the two eccentric plates 14 are fixed to the rotary shaft 12, the link 15 is coupled to each of the eccentric plates 14 via bearings, and one of the links 15 is coupled to the compression piston 16 of the primary compressor 1, and One of the link members 5 is coupled to the compression piston 17 of the secondary compressor 2. The compression piston 16 of the φ primary compressor 1 is a rocking piston and is slidably housed in a cylindrical compression cylinder 2〇. The compression piston 17 of the secondary compressor 2 is a general piston' slidably housed in a cylindrical compression cylinder 21. Further, in the case of the compression cylinder 2 of the primary compressor 1, the atmosphere is introduced into the air. That is, the atmosphere is introduced into the machine from an intake hole (not shown) formed in the casing cover 18 of the casing 3. In the inside of the crucible 3, the introduction hole (not shown) attached to the check valve formed in the compression piston of the primary retracting machine 1 is introduced into the compression cylinder 2{). Further, the primary compressor 1 and the secondary compressor 2 are connected via the first pipe 22, and the secondary compressor 2 is 7042-9855-PF; Tungming 23 200925421 • and the square trunk 6 are connected via the second pipe 23 connection. The two air grooves 6 are in communication. In the above configuration, when the motor 4 is actuated, since the rotary shaft 12 is rotated, the rotary motion is converted to the straight forward reciprocating motion by the eccentric plate 14 and the link 15 of the secondary compressor 1, and the compression piston 16 is compressed by the steam rainbow 2 ( ) Reciprocating action inside. The compression activity S 16 ϋ is moved back by the suction step #, the space in the compression cylinder 20 is rapidly expanded, the inside becomes a negative pressure, and the line in the above-mentioned pressing hole opening 'machine E 3 is guided to the compression cylinder 2(). Next, when moving to the compression step and the compression piston 16 advances, relatively, since the space in the lock 3 is rapidly expanded, air is introduced into the machine E 3 from the air introduction port formed in the cover 18 while Since the space in the compression cylinder 2 is contracted and compressed, the introduction hole is closed, and the discharge port (not shown) formed in the compressed steam red 20 is opened, and the compressed air is discharged. The primary compressed air that is discharged is supplied to the compression cylinder 2 of the secondary compressor 2 through the first pipe 22'. The primary air pressure in the compression cylinder 21 is similarly compressed by the compression piston 17 that reciprocates. At a high pressure, it is discharged as secondary compressed air, and is supplied to the air tank 6 by the second pipe 23 to be stored. Further, the air grooves 6 and the machine E 3 and the air grooves 6 are coupled by a connecting bracket (not shown). The metal converter mounting plate 24 is disposed in the lower portion of the compressor main body 5. As shown in Figs. 6 and 7, the cover 7 is attached to the periphery of the compressor main body 5, and a handle made of synthetic resin is attached. Mounted at both ends of the compressor body 5. The ampoules of the cover 7 and the handle 25 will be described later. ~ (cooling structure of compressor according to one fan) 7042-9855-PF; Tungming 24 200925421 * Next, as shown in Figs. 3 to 5, the front end of the rotary shaft 12 of the motor 4 protrudes outward. The cooling fan 26 is fixed. On the side of the cooling fan 26 side of the motor & 'the center opening and the end of the wind deflecting disk 27 which is opened in a funnel shape are arranged. Thereby, the cooling air system blown by the cooling fan 26 is branched into the internal cooling air a guided to the inside of the motor 4 by the air guiding disc 27, and guided from the outside of the air guiding disc 27 to The outside of the motor 4 cools the wind b. In addition, as shown in Fig. 9, the air guide circular plate 27 is composed of an annular circular plate 28 fixed to the center of the end portion of the motor 4, and a wind guide disk main body 29 disposed around the same. The connecting piece 30 provided between the annular disk 28 and the air guiding disc main body 29 is disposed at a position that does not block the ventilation space S formed between the coils of the motor 4. On the upper portion of the casing 3 side of the motor casing 8, two exhaust holes 31 for discharging the internal cooling air a are formed. In the lower aspect, the suction holes 32 that guide the external cooling air b into the motor 4 are formed. Next, as shown in FIG. 3, FIG. 7, and FIG. 10, in the lower portion of the motor 4, the external cooling air b is guided to the first air guiding plate 36 of the lower air suction hole 32 of the motor 4. And a second air deflector 37 guided to the compressor is continuously provided. A gap 4 is formed between the lower end of the first air deflector buckle and the mounting plate 24 of the current transformer 38. The second air deflector 37 is formed such that the outer cooling air b is turned from the lower side of the compressor to the upper side of the inner side, and the rear portion 41 is formed upright. According to the above configuration, when the cooling fan 26 is actuated and the cooling air is blown to the side of the scraper main body 5, as shown in Figs. 3, 4, and 5, 7042-9855-PF; Tungming 25 200925421 The internal cooling air a' guided by the wind guide disc 27 to the inside of the motor 4 can smoothly pass along the ventilation space s between the coils. Therefore, the coil can be preferably cooled by continuously feeding fresh cooling air continuously. Further, as shown in Fig. 10, the outer cold portion wind b also enters the inside of the motor * from the lower suction hole 32 of the motor 4 by the first air deflector 36, and the exhaust hole 31 from above. The rear part of the motor 4 is cooled by the exhaust. Further, the 'external cooling air system is guided by the second air guiding plate 37 to the primary and secondary compressors 2, 2 which are prone to heat generation due to the compression heat, and the external cooling air is not only contacted once but also the secondary compressor 2 Since it is concentrated as shown in Fig. 7 on the lower side and the crotch side, the amount of contact of the cooling air is large for these primary and secondary compressors 1, 2, and the cooling effect is very high. Further, a part of the external cooling air b blown to the air deflector 36 is passed through the gap 4 〇 along the gap 4 of the women's board 24 of the converter as shown in FIG. 3 and FIG. The upper surface flows linearly and is exhausted, and the fresh cooling air on the mounting plate μ is constantly flowed. During the compression operation, the converter 38, which controls the rotation of the horse 4, is prone to heat, and the operation of the cooling is stabilized. Further, the first pipe "connecting the primary compressor" and the secondary compressor 2 and the second pipe connecting the secondary compressor 2 and the air tank 6 of the first stage are piped to the upper portion of the compressor body 5, and will be The second tube 23 is disposed on a side close to the cooling fan 26, 曰μ, +, I, and the two first tubes 22 and the second tube 23 are for the flow of the cooling air, and the first s 22 The upper and second tubes 23 are piped in a different height in the lower state. Therefore, the mountain is &Gaila.. This is because the two tubes 22 and 23 are easily exposed to the cooling air, and are efficiently Cooling. 7042-9855-PF; Tungiuing 26 200925421 Next, the cover 7 is also formed to control the flow of the cooling air. That is, as shown in Fig. 4 and the like, the suction holes 34 of the cover 7 are correspondingly The side surface of the cooling fan 26 and the front surface of the front side of the cooling fan 26 are formed, and the exhaust hole 35 is disposed on the downstream side of the compressors ? and 2. Further, on the inner side surface of the cover 7 and the compressors, 2 In contrast, the external cooling air b flows along the inner surface of the cover 7 and is guided by the compressors i and 2. Air passage 42 is formed so 'is by the cooling air flow from the intake to the exhaust Φ until

The smoothness of the wind can be used for cooling without wasted in a part. Further, in the inner surface of the cover 7, as shown in FIG. 2, FIG. 3, and FIG. 5, the wind deflector 43 is formed to hang down along the downstream side of the first pipe 22 that is away from the cooling fan 26. The cooling air flowing along the upper wall surface of the cover 7 is guided back to the above [the downstream side of the pipe 22 by the air deflector 43. As described above, the first tube 22 on the side far from the cooling fan 26 is harder to cool than the second tube 23 on the approach side, but the cooling air flowing along the upper inner surface of the cover 7 is forced by the wind deflector 43 Since the ground flow is guided to the inner side of the downstream flow of the first pipe 22, the amount of contact with the pipe cooling air is large, and the cooling effect is not attenuated even in the first pipe 22 on the side far from the cooling fan 26. As described above, the cooling air from the cooling fan 26 is branched into the internal cooling air & guided to the inside of the motor 4 by the air guiding disc 27, and guided to the motor 4 from the outside of the air guiding disc 27. The outer external cooling air is in the motor box 8, on the upper and lower portions of the machine E 3 side, respectively forming an exhaust hole 31 for discharging the internal cooling air a and directing the external cooling air U to the horse 7042-9855-PF; Tungming 27 200925421 Intake hole 32 in 4, and between the inner side surface of the cover 7 and the primary and secondary compressors 2, the passage of the external cooling air 13 along the inner surface of the cover 7 passes once, The secondary compression is configured by the air passage 42 that is guided by the second cooling, and the cooling air is cooled by the internal cooling air a guided by the air guiding disc 27, because the outer side of the air guiding disc 27 is The external cooling air b also flows from the intake hole 32 in the lower portion of the motor case 8 to the exhaust hole 31 in the upper portion, and the inner side of the motor 4 flows downward and upwards to be cooled, so that the motor 4 can be efficiently performed. cool down. x, the external cooling air b flows along the inside of the cover 7, which is the fastest because it becomes the highest during operation.

The warm compressor is cooled by the high-speed cooling air guided along the inner surface of the cover 7, and is efficiently cooled. Therefore, since the compressor body 5 can be cooled only by the above-described cooling fan 26, the conventional multi-blade fan can be omitted. Therefore, it is possible to achieve a large size and weight reduction of the air compressor. (Connection structure of the transfer pipe for compressed air) Next, the first pipe 22 and the second pipe 23 are cooled by the external cold portion wind b as described above, because the secondary compressor 2 is discharged from the second stage. The compressed air is at a high temperature, and the second tube 23 is more cooled than the first tube 22. Further, since the first pipe 22 is connected to each of the compressors having the same vibration, there is almost no problem, but the second pipe 23 is in the compression operation, and the heartbeat and the generated vibration resonate to avoid this phenomenon, as described below. Composition. That is, the second tube 23 system, as shown in Fig. 11 and Fig. 12, is further turned into the opposite side from the lower portion of the cylinder head of the secondary compressor 2 toward the upper portion of the casing 3. The lower portion is formed by a long-formed 7042-9855-PF; Tungming 28 200925421 is a heat-suppressing tube copper tube 44, and a flexible tube 45 extending from the rear to the rear and connected to the rear portion of the air tank 6. As described above, the length of the tube is set to be extremely longer than that of the first tube 22, and the area of the external cooling air b is made larger.

Further, one end of the steel pipe 44 is connected to the cylinder head of the secondary compressor 2, and the other end is connected to the end of the flexible pipe 45. The copper pipe 44 and the connecting member 46 of the flexible pipe 45 are fixed to the mounting bracket 47 of the metal plate fixed to the lower surface of the casing 3 via the elastic body. The donut-shaped elastic body 48 is worn by the ampule bracket 47' as shown in Fig. 13, and the outer peripheral surface of the copper pipe 44 and the connecting member 46 of the flexible tube 45 is coupled to the center hole of the elastic body 48. The state in which the inner peripheral surface is slightly contacted is supported by the fitting. In the compression operation, 'mainly the motor 4 and the primary and secondary compressors 1, 2 are vibrating' because the primary and secondary compressors 2 and the casing 3 are integrally combined, so the machine E 3 also vibrates the direction of these vibrations. the same. Both ends of the above-mentioned copper pipe 44 are supported by the secondary compressor 2 and the casing 3, and are hard to resonate because of the same vibration direction. Further, since the outer peripheral surface of the connecting member 46 at the end of the copper f 44 & is disposed so as to slightly contact the inner peripheral surface of the center hole of the elastic body 48, the vibration on the side of the connecting member 46 is absorbed, and cracks or the like do not occur. . In the case of the Teflon (registered trademark, the tree is covered with a stainless steel mesh), it is flexible in the longitudinal direction, but it is flexible. The flexible tube 45 is disposed in the front portion from the connection portion with the copper tube in the front direction and is connected to the air tank 6 via the connection bracket 33. 7〇42-9855-PF; Tungining 29 200925421 During compression operation The generated vibration system is mainly caused by vibration in the vertical direction caused by the rotation of the motor 4 and vibration in the horizontal direction caused by the reciprocation of the compression 2 plugs I6 and 17 of the secondary and secondary compressors 1 and 2, In the other direction, the 缕I4 丫 丫 没有 没有 缕 缕 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 Or the deformation does not occur. Therefore, the durability is improved. As a general description, the second tube 23 is composed of a copper tube of a cooling efficiency: an excellent flexible tube 45, and will come from the secondary compressor 2 tube!::: Cooling, can be sent to the air tank 6. Also, due to the high price of flexibility: It is preferable that the second tube 23 is half-length of the entire length of the second tube 23, and can be pressed at a low price and is a copper tube of a high exothermic tube, and is preferably a material for exothermic heat or a material having thermal conductivity. In addition, the steel pipe system is a part of the outer circumference of the cooling fan 26 that is required to be cooled by the cooling fan 26 and is subjected to the cooling fan 26, and is at least half of the outer circumference of the cooling fan 26. u is better. Moreover, the flexible tube 45 series is better sighed in the secondary and secondary compressors.

Further, the connecting pipe is not limited to the above-described M map and the flute structure. For example, it may be constituted by a free joint pipe as shown in Figs. 14 and 15 . In other words, the connecting pipe system is formed by connecting a metal pipe (not shown) such as two coppers to the fixed side. The free joint 59 is a joint 53 and is connected to the first joint portion 49 and the second joint portion 50 of the mouth of the two fields. The mouth has openings 53 and 55 7〇42-9855-PF; Tungming 3〇200925421* . The first joint portion 49 has a spherical concave portion 52 inside the end portion of the tubular portion 51 connected to one of the tubes, and an opening portion 53 is provided on the opposite side of the cylindrical portion 51 of the concave portion 52. In the inner edge of the opening portion 53, an elastic sliding material 54 (a 0-ring may be attached) is attached. On the other hand, the second joint portion 5 is formed in a tubular shape, and is coupled to the side opposite to the side of the other tube, and is rotatable from the opening portion 53 of the first joint portion 49 to the concave portion 52 in a certain range. The inside is inserted and cannot be pulled out. Therefore, the seal ring 56 is installed at the front end portion of the second joint portion 50, and the edge portion 57 is formed before the seal ring 56. The edge portion 57 is formed to be larger than the inner diameter of the opening portion 53 of the first joint portion 49 to prevent extraction, and the seal ring 56 at the tip end is biased in close contact with the concave surface portion 52 by the elastic force of the sliding member 54. Further, the outer diameter of the portion of the outer side of the edge portion 57 corresponding to the opening portion 53 of the first joint portion 49 is smaller than the inner diameter of the opening portion 53. The inner side of the seal ring 56 is attached to the tube of the first joint portion 49. The portion 51 is open. Therefore, the joints of the two metal pipes can be changed in all directions except for the expansion and contraction direction. Since the compressor body 5 is not vibrated in the front-rear direction, the free joint 59 can be disposed in the front-rear direction, thereby effectively absorbing the compressor. Vibration 0 (mounting structure of the cover) The above-mentioned cover 7 is not only for cooling of the motor 4 or the compressor, but also for the safety of the operator, and also has a noise prevention function. In order to suppress the occurrence of this noise, the cover 7 is attached as follows. That is, the cover 7 is fixed to the air grooves 6 on both sides of the handle 25 on both end sides of the longitudinal direction 7042-9855-pf; Tungming 31 200925421 of the compressor main body 5. As shown in Fig. 16, Fig. 18, Fig. 21, etc., the cover mounting groove 58 is formed in the handle holder (the handle 25 of the front handle is also the same), and the cover mounting bracket 6 is fixed to the air groove 6, and The mounting piece formed by the dog at the lower end of the front and rear of the cover 7 (refer to Figs. 6 and 16) is inserted into the cover mounting groove via the thick plate-shaped first cushioning material 62' by the lower side of the cover 7 The second second cushioning material 63 (refer to FIGS. 1 and 20) is screwed to the lid mounting bracket 6A to be fixed. Here, the handle 25, the handle 25 is referred to as a micro-description, and as shown in Fig. 18, the two handle frames 65 are erected above the both sides of the mounting frame portion 64 of the base, and the handle frame 65 is The upper end is connected by the grip portion μ = the intermediate rod 67 is provided in the middle. Further, when the handle 25 is viewed from the side, it is curved in a U-shape, the upper portion and the lower end portion are formed substantially perpendicularly, and the lower portion of the intermediate rod 进入 is bent toward the inner side (the compressor body 5 side). Further, a through hole (air introduction hole or vent hole) is formed inside the mounting frame portion 64. The opposite zigzag mounting bracket 68 is provided at the front and rear ends of the converter mounting plate 24 disposed at the lower portion of the compressor housing body 5. The handle 25 is attached so that the lower end portion of the attachment frame portion 64 is supported by the horizontal piece 7〇 of the lower portion of the attachment bracket 68, and the inner side surface of the attachment frame portion 64 abuts against the vertical of the mounting bracket 68. The sheet 71 is fixed by a screw Μ. The cover mounting groove 58 of the handle 25 described above is attached via the first cushioning material 62 when the cover 7 is attached. The first cushioning material 62 is made of an elastic material such as rubber. As shown in Fig. 18 and 19(a) to 19(c), the end portion is formed at the end portion and inserted into the above 7042-9855-PF; Tungming 32 200925421 - The insertion portion 72 of the cover mounting groove 58 is formed at the other end with the inserted portion 74 of the insertion groove 73 of the attachment piece 61 inserted into the cover 7 to constitute 'the upper surface and the bottom surface of the insertion groove 73 of the inserted portion 74. A plurality of ridges 75 that are spaced apart in contact with each other in the left-right direction are formed in parallel at a position below the inserted portion 74, and a projection 76 is formed between the ridges 75. . For the cover mounting groove 58 of the handle 25, when the cover 7 is mounted, as shown in FIGS. 16 and 18, first, the insertion portion 72 of the first cushioning material 62 is inserted into the mounting groove 58 of the handle 25, and the cover is placed. The attachment piece 61 of 7 may be inserted into the insertion groove 73 of the first cushioning material 62. Next, as shown in Fig. 20, mounting holes 77 (refer to Fig. 6 and Fig. 2) are formed on the lower portions of both sides of the cover 7, and are mounted vertically by fixing screws 78' through the mounting holes 77. The cover mounting bracket 60 provided in the air tank 6 is performed via the second cushioning material 63 at this time. The second cushioning material 63 is formed of an elastic material made of an elastic material such as rubber, and is formed in the insertion hole 82 through which the center fixing screw 78 is inserted, and is fitted to the mounting hole 77 of the cover 7 on the surface. The fitting groove of the inner edge is shaped such that the first side is attached to the cover mounting bracket 6 of the air groove 6. When the time is fixed, the front end of the second buffer material 63 is inserted into the mounting bracket 60 of the gage groove 6. It is fixed to the cover 7 and is inserted through the horizontal first cushioning material 62, and the cover on both ends of the longitudinal direction of the compressor main body 5 is mounted 33 ^^-9855-PF; Tungming 200925421 groove 58. The direction of the vibration of the retractable main body 5 is mainly in the up-down direction or the horizontal direction of the left and right, but since the insertion groove 73 of the first cushioning material 62 is formed in the horizontal direction, the horizontal direction of the front and rear ampules 61 of I7 The vibration is absorbed by the insertion groove 73. Further, the vibration of the vertical direction of the mounting piece 61 is absorbed by the protrusion 75 of the upper surface and the bottom surface of the insertion groove 73, and under the insertion portion 74, because the protrusion 76 The meat portion is formed between the protrusions 75, so that the meat portion of the groove bottom of the insertion groove 73 is promoted between the protrusion 75 and the protrusion 76, and the meat portion is deformed by a wave, and the vibration is absorbed. Effectively, the vibration system is difficult to transmit to the cover 7 . Further, since both sides of the cover 7 are screwed via the vertical second cushioning material 63, the vibration in the up and down direction is effectively absorbed by the first cushioning material 63. It is difficult to communicate to the disk 7. Therefore, according to the above-described mounting aspect, the noise caused by the vibration of the cover 7 can be reduced. Further, since the vibration of the screw is absorbed by the second cushioning material 63 on the screw side, the vibration of the air groove 6 side is hard to be transmitted to the cover 7. Further, since the fixing position of the cover 7 can be reduced, the assembly work I or the disassembly work at the time of repair can be easily performed. Further, the front and rear mounting postures of the cover 7 and the left and right mounting postures may be reversed from the above-described configurations. Further, in the embodiment, the configuration in which the air groove is disposed on the lower side of the compressor main body is described. However, when the air groove is disposed on the upper side of the compressor main body, the cover mounting bracket is provided to the compressor. It is also possible to use the body side and the fixed cover. (The fall prevention structure with the hanging member) Next, as shown in Fig. 21 to Fig. 24, in the case of fixing the cover 7 for the 7042-9855-PF; Tungming 34 200925421 hand 25 The strap member 85 of the shoulder strap to be used is loaded.

That is, the belt-hanging member 85 has a size that is accommodated between the handle pivots 65 on both sides of the handle 25, and the lower end portion 89 is attached from the handle by an annular metal member having a substantially identical shape. The space below the intermediate lever 25 25 enters the inner side, and the lower end portion of the strap member 85 is engaged with the engaging groove 86 formed on the vertical surface of the lower end portion of the handle 25. The handle 25 is attached to the horizontal piece 7 of the lower portion of the mounting bracket 68 of the air groove connecting frame (not shown) which is a base portion of the two-compressor as described above. Supported above, the inner side surface of the mounting frame portion abuts against the vertical piece 71 in the middle of the Annon bracket 68, and is fixed by the screw 79. Therefore, the engagement of the lower end portion 89 of the hanging member 85 is engaged. The groove 86 is blocked by the mounting bracket 68, and the tape hanging member 85 is unlikely to be supported in the engagement groove 86. As described above, the tape hanging member 85 is only engaged by the handle of the handle 25. Since the groove 86' is fixed by the handle 25, it is easy to mount the handle, and the cost can be lowered. Further, the upper portion of the engagement groove 86 is inclined outward, but the engagement portion 87 is formed at In the upper portion, the cover mounting groove 58 is formed at the upper end portion thereof, and the engaging portion 87 is engaged by the lower end portion of the tape hanging member 85, and in a state where the tape hanging member 85 abuts against the intermediate rod 67, When the pull-up member with the hanging member 85 is led to the upper side, the 'hanging member 85 @ lower end portion is attached to the above-mentioned engagement 8 7 is stuck and can be formed without being pulled out. As described above, the lower end portion of the tape hanging member 85 is engaged with the hook formed at the lower end portion of the hand 7042-9855-PF; Tungming 35 200925421 hand 25 When the opening of the t. 86 is spliced and the above-described engagement is fixed, the hand is attached to the compressor main body 5, and the hand 25 is fixed to the mounting bracket tape-hanging member 85. Because it can be fixed at the same time, it can be pressed at a low cost. ', the fixing is performed by using a bolt or the like, and the upper portion of the engaging groove 86 is attached to the upper portion of the engaging groove 85, and the engaging portion of the end portion is used, for example, when the handle 25 is raised to the upper side. That is, the engagement groove 86 that can be engaged with the lower handle is broken, etc., in the air compressor, when the air is lowered, and the belt hanging member 85 is disengaged from the engagement groove 86 to the upper side, the belt Hanging 1 is improved by the engagement portion 87 of the air mixer, and the lower end portion of the hanging mechanism 85 is engaged with the handle 45 of the Lu Xing (4) piece 85, because the upper portion is suspended, in the two-gas compressor The center side is pulled 67 as a center, and the hanging member 85 (10) is rotated so that the lower end portion of the middle lever of the handle 25 is pressed against the engaging portion 87, so that it is held at the end of the hood. The belt hanging member 85 does not fall off. Therefore, the drop of the two-milk compressor is stopped on the way, and the damage or accident is avoided.
