Description

Vinyl greenhouse Dog, closure device

The present invention relates to an improved invention of a vinyl house switch, and more particularly, according to the growing conditions of crops grown in a vinyl house, opening and closing the side of the vinyl house or ceiling for the purpose of controlling the appropriate temperature and preventing rainwater. It relates to a vinyl house switch that can be opened and closed by rolling the vinyl and the insulation cover and the like to be possible.

In general, a vinyl house is a device that allows crops to be grown without being affected by outside temperature, and is formed by covering vinyl in a frame formed by bending pipes to block outside air. It may be installed by adding a light shielding film.

In addition, in recent years, not only the cultivation of crops, but also the use of plastic houses such as barns and mushroom growers is increasing in various fields.

On the other hand, such a vinyl house is formed to open and close the side and ceiling of the vinyl house in order to control the temperature in the vinyl house, and at this time to open and close the vinyl and the insulation and the light-shielding film, etc. As a means, a vinyl house switchgear is used.

The vinyl house switchgear combines a horseshoe on the output shaft to open and close the vinyl or insulation.

Therefore, since the vinyl house switch is always coupled to the output shaft of the end of the vinyl or the insulation is rolled, the output shaft generates a rotational force to release the vinyl or insulation.

Therefore, the vinyl house switchgear must be able to control the torque generated from the output shaft.

That is, the switch must be able to wind the rotational force generated from the input shaft through the output shaft as it is, so that the wheel can wind the vinyl, insulation and light shielding film. .

Conventionally, a variety of switchgear for opening and closing a plastic house as described above has been proposed and used, and its configuration has also been variously proposed.

As an example, as in Utility Model No. 0142185, a driving shaft formed with two gears having a first gear and a second gear having different gear numbers is formed, and an internal gear is inserted into which the driving shaft is fitted. And a rotating body having a lower shaft formed therein, an internal rotating body engaged with the internal gear of the lower case, a driven shaft engaged with the internal gear of the internal rotating body, and the driving shaft being coupled to one side thereof, and the outer rotating body. The planetary gear-type vinyl house switchgear composed of an upper case coupled to a lower case and formed with a guide hole and a handle, and a winding tube formed on the case as in Patent Registration No. 0313103, and a coil spring installed on the winding tube. Both ends of the coil spring are rotated in the winding or unwinding direction to reduce the diameter of the coil spring and press the winding tube to break and support And greenhouses coil actuator of the spring clutch system to release the braking and to make the idle-up,

As in Patent Registration No. 1408386 and Utility Model Registration No. 290122, a ratchet is combined with a driven gear and a central axis, and a ratchet gear and a disk are sequentially installed on both sides of the driven gear, adjacent to the driven gear, and the ratchet is loaded with spring. As the driven gear rotates, it moves left and right along the spiral of the driven gear's central axis, and the ratchet gear and disk and the side of the driven gear come into close contact with each other and the ratchet gear is engaged with the ratchet gear to prevent rotation of the ratchet gear. Ratchet gear-type vinyl house switchgear which prevents rotation of frictional driven gear is also proposed and used.

However, the above-described conventional vinyl house switch includes a plurality of gears or stoppers in order to prevent reverse rotation in a rotating direction and to support bidirectional support, but the structure is complicated and many devices are installed. There is a problem that is difficult and not durable. In particular, the coil spring clutch type vinyl house switchgear that reduces the diameter of the coil spring by pressurizing the winding pipe and expands the diameter by idling to release the braking is the grease Lubricant such as back flows between the winding tube and the coil spring, which is a slip phenomenon between the winding tube and the coil spring that operates the braking operation, so it is difficult to expect accurate operation, and the ratchet gear moves to the left and right along the spiral of the central axis. And the side of the disk and the driven gear The ratchet gear-type vinyl house switch with braking generates the idling of the hysteretic axis according to the amount of movement of the driven gear left and right along the helix, which reduces the sense of operation and makes it difficult to expect the correct amount of winding and loosening of the vinyl. And the noise generated by the operation of the ratchet gear, the plastic house used as a livestock house is subjected to the stress of the livestock raised by the noise, and thus the use is restricted. The driven shaft and the input gear are formed as spur gears. Alternatively, the center of the output shaft is parallel and is spaced by the pitch diameter of both gears, so either the input shaft or the output shaft cannot be located at the center of the case. The volume of the case as it is coupled to one side from As well as increase. There is a problem that the installation and use is limited and the number of parts is large, productivity is lowered, and manufacturing costs are increased.

Patent Registration No.0513103 Patent Registration No. Utility Model Registration No. 0142185 Utility Model Registration No. 290122

The present invention has been made to solve the above-mentioned conventional problems, so that the center of the output shaft and the input shaft to match and to be located at the center of the case, so that the coupling member installed on the input shaft and the output shaft can also be coupled at the center of the case Therefore, the purpose of the present invention is to reduce the manufacturing cost by minimizing the vinyl house switchgear and to configure the vinyl house switchgear with a simple configuration, and to prevent the generation of noise by operation.

In addition, there is another object of the present invention to propose a vinyl house switchgear excellent in the precision of operation to accurately control the amount of winding and unwinding of the vinyl.

In order to achieve the above object, the present invention has an operating tool side external contact type (31) formed in the operating hole (3) eccentrically rotated by the eccentric cam (20) which is integrally operated with the center different from the input shaft (2) Engage with the case-side internal contact mold 11 formed integrally with the case 1, and the operation-side external contact mold 31 rotates along the case-side internal contact mold 11 by rotation of the eccentric cam 20. Due to the number of teeth of the spherical outer foldable mold 31 and the case side inner foldable mold 11, the operating spherical outer foldable mold 31 rotates along the outer periphery of the eccentric cam 20, and the operating tool 3 and the output shaft 4 are rotated. The driving force of the input shaft (2) is decelerated by the number of teeth of the actuating side external contact type (31) and the case internal contact type (11), and the output shaft (4) is rotated in the opposite direction to the rotation of the input shaft (2). Rotational force is transmitted and the rotational force input from the output shaft (4) is the operating port side Since the folding mold 31 does not revolve along the case-side internal folding mold 11, the rotational force of the output shaft 4 is restricted by the engagement of the operation opening-side external folding mold 31 and the case-side internal folding mold 11 so as to break. will be.

The present invention as described above can be obtained by driving the outer side contact type and the inner side contact type of the inner side of the eccentric cam drive to obtain a smooth feeling of operation and to obtain a plastic house opener that can be braked in the correct position by braking There is an advantage to this.

In addition, by braking the rotational force input from the output shaft (4) by the power transmission configuration, by excluding the configuration for braking such as the latch and the latch gear, the vinyl house switch can be easily configured to simplify the assembly and at the same time the assembly of the vinyl house switch. In addition, since noise is not generated during operation, it can be used even in a sensitive place such as a barn, so it can be used for various purposes and has another effect of reducing manufacturing cost by reducing the number of parts.

According to the present invention, the operation-side external contact type 33 which is eccentrically rotated by the eccentric cam 20 operating integrally with the input shaft 2 is engaged with the case-side internal contact type 11 along the case-side internal contact type 11. At the same time as the revolving box, the inner side of the eccentric cam 20 is formed on the outer circumferential surface 21 of the eccentric cam 20 by the number of teeth between the case side inner fold type 11 and the operating lateral side fold type 31. While rotating in the reverse direction of the rotation direction, the case side internal contact type 11 and the operation port side external contact type 31 are decelerated by the number of teeth so that the operation tool 3 is rotated, and the operating tool side internal contact type (1) 34) is formed and engaged with the output shaft tooth mold 40 formed integrally with the output shaft 4 so that the rotational force of the operating tool 3 is transmitted to the output shaft 4 to be driven, and is input from the output shaft 4 to the operating tool. The rotational force transmitted to (3) is such that the eccentric rotation of the operating port side external contact type 31 is engaged with the case side internal contact type 11. State is fixed so that the braking will by the coupling of hameuroseo not revolving along the housing side internal teeth (11) working port side external teeth 31 and the case-side internal teeth 11. To be more specific it as follows.

2 and 3 are exploded perspective views showing the configuration of the present invention.

The vinyl house opening and closing device according to the present invention has an input shaft hole 10 at one side center and an input shaft having a case 1 having a device space 14 therein, and an eccentric cam 20 which is formed integrally with different centers ( 2) and the operation tool formed with the cam groove 30 in the center of one side, and the operating tool side outer contact type 31 is formed in the outer side of the cam groove 30, and the operating tool side inner contact type 34 is formed in the center of the other side. (3), an output shaft 4 which is integrally formed and has an output shaft tooth type 40 on one side, and a cover 5 that is coupled to the case 1 to cover the device space 14 of the case 1. It is configured by.

The case 1 has an open side and an apparatus space 14 is formed therein, and an input shaft hole 10 is formed in the center of the front wall, and the case side inner contact type protrusion 12 is formed on the inner circumferential surface of the apparatus space 14. It is comprised by forming the case side internal contact die 11 comprised by the case side internal contact groove 13. As shown in FIG.

The input shaft 2 is formed by integrally forming an eccentric cam 20 that is different from the input shaft 2 on one side.

The actuating tool (3) forms a cam groove (30) at the center of one surface, and the actuating device on the outside of the cam groove (30) is composed of an actuating side outer contact type projection (32) and the actuator side outer contact type groove (33) It is configured by forming an actuating side inner tangular mold 34 composed of an actuating side inner tangible protrusion 35 and an actuation side inner tangible groove 36 on the other side 31.

The output shaft 4 is configured by forming an output shaft tooth die 40 consisting of an output shaft toothed protrusion 41 and the output shaft toothed groove 42 on one side.

The cover 5 is configured to form an output shaft hole 50 in the center portion of the device space 14 inside the case 1 in combination with the open one surface of the case 1.

On the other hand, the support shaft 22 may be formed on one of the input shaft 2 or the output shaft 4, and the support shaft groove 43 may be formed on the other.

5 and 6 show an assembly embodiment of the present invention having the above configuration.

That is, in the present invention, the input shaft 2 is inserted into the input shaft hole 10 so that the eccentric cam 20 is positioned inside the device space 14 of the case 1 so that the end protrudes out of the case 1 so that the rotation is possible. Combining and combining the cam groove 30 of the operating port 3 and the eccentric cam 20 of the input shaft (2), so that the center of the operating sphere (3) coincides with the center of the eccentric cam (20) to the input shaft (2) From the cam groove 30 of the position where the eccentricity is the largest and the eccentric amount is formed on the outer side of the operating groove side external contact mold 31 (tooth teeth located outside the top dead center of the eccentric cam) as shown in Figure 5 It is assembled with 11).

On the other hand, the output shaft 4 is coupled to the output shaft 4 to the output shaft hole 50 so that the output shaft tooth type 40 is located on the inner side of the cover 5 to protrude the end of the cover 5 to the outside of the case ( When combined with 1) and the cover 5, the output shaft tooth 40 is engaged with the actuating side internal contact type 34 of the actuating tool (3).

In more detail, as shown in FIG. 6, the operating tool 3 is eccentrically assembled by the eccentric cam 20 according to the eccentric amount of the eccentric cam 20. Actuator side internal contact type having a 34 is assembled to engage with the output shaft toothed type 40 at the position where the eccentricity is the opposite side that the operating side external contact type 31 and the case side internal contact type 11 meshes.

In the present invention assembled as described above, the center of the input shaft (2) and the output shaft (4) is located on the same axis line and the center of the eccentric cam (20) and the operating port (3) is located on the same axis line and the input shaft (2) And the center of the output shaft 4 and the center of the eccentric cam 20 and the operating port 3 has a deviation.

Therefore, since the actuating side external contact type 31 and the actuating side internal contact type 34 have an eccentricity from the center of the input shaft 2 and the output shaft 4, the actuating side external contact type 31 and the actuating side external contact type 31 are different from each other. In addition, the actuating side internal contact type 34 is to be engaged with the output shaft tooth type 40.

On the other hand, the input shaft 2 and the output shaft 4 supported by the case 1 and the cover 5, respectively, are configured to be rotatable by inserting the support shaft 22 into the support shaft groove 43 so that the input shaft 2 and the output shaft 4 can be rotated. ) Can complement strength and precision with the shaking of the center.

If described in detail with reference to the accompanying drawings, the embodiment of the present invention the operation of the present invention as follows.

As shown in FIG. 7, the outer side teeth contact type 31 of the operating tool 3 coupled to the eccentric cam 20 has a tooth located farthest from the center of the input shaft 2a. As the angles are added to both sides with respect to the summed and joined teeth, the engagement amount is reduced and assembled.

When the operating tool 3 assembled as described above drives the input shaft 2 to rotate the eccentric cam 20, the operating tool side external contact type protrusion 32 is inserted into the case side internal contact type groove 13 and the operation port side external contact type The case-side internal contact type protrusion 12 is inserted into the groove 33, which is sequentially and continuously formed.

On the other hand, the case side inner contact type 11 and the operating port side outer contact type 31 have a tooth number difference.

That is, the case-side internal contact type 11 having a large radius from the center is formed with a large amount of tooth grooves and tooth protrusions, and the operation radius-side external contact mold 31 with a relatively small radius is formed with a small number of tooth grooves and tooth protrusions. .

This means that the case-side internal contact type 11 having a large radius means that the angle between the case-side internal contact type protrusion 12 and the neighboring case-side internal contact type protrusion 12 is small, so that the operation opening side external contact type 31 having a small radius is It is relatively larger in angle than the case-side internal contact type 11.

Therefore, when the eccentric cam 20 is rotated about 90 ° from the center line D of the engagement portion of the case side inner fold type 11 and the operation side outer fold type 31 overlapped with each other, the center line of the case side inner fold type 11 is overlapped. (a) and the center line (b) of the actuating side outer contact type 31, when the deviation (c) occurs and the case side inner contact protrusion part 12 and the actuating side outer contact groove 33 join together, the case side inner contact type (11) is formed integrally with the case (1), the rotation is impossible, so the operating port (3) formed with the operating tool side external contact type 31 is the direction in which the eccentric cam (20) rotates along the outer circumferential surface of the eccentric cam (20) It will be rotated by the opposite angle (c) in the opposite direction of the eccentric cam 20 is increased as the rotation of the eccentric cam 20 is increased.

Therefore, the operating tool 3 is rotated by the continuously rotating eccentric cam 20, and the output shaft 4 engaged with the operating tool 3 is rotated, and the rotational force input from the output shaft 4 is the case-side internal contact. Since the actuating tool 3 cannot be rotated by the actuator side external contact type 31 meshed with the tooth 11, the rotational force is controlled. In particular, the actuating tool 3 acts as a rotational direction acting on the actuating tool 3. As the direction in which the operating tool 3 rotates is reversed, the rotational force input by the output shaft 4 is controlled.

Meanwhile, in the present invention, the output shaft 4 is configured to transfer the rotational force of the actuating tool 3 to the output shaft 4 by joining the actuating tool 3, the actuating side internal contact type 34 and the output shaft tooth type 40. The action is the same as the action of the coupling between the case side internal contact type 11 and the operation side external contact type 31 described in detail above, but the number of teeth of the operation side internal contact type 34 is small and the number of teeth of the output shaft tooth type 40 is small. Therefore, the rotation speed of the output shaft 4 is increased.

In addition, when the operating shaft is internally inverted type and the externally indented type is formed in the operating tool 3, the rotational speed of the output shaft 4 is decelerated, and the operating tool 3 and the output shaft 4 having different center axes are reduced. Although not shown in the drawings to connect the drive may be configured through a universal joint or the like.

In addition, the present invention mouth Various driving means, for example, handles, chain pulleys, motors, etc. may be selectively coupled to the force shaft 2.

Accordingly, the present invention is composed of a manual (side) switch, a chain (ceiling) switch, and a motor in accordance with the driving means of the input shaft (2) and the electric switch.

In addition, the present invention may be configured as a shaft use switchgear and a winch by coupling the wire winding drum and the like to the output shaft (4).

Therefore, the present invention is not limited to the embodiments of the above-described features, and any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims may make various modifications. Of course, such changes will fall within the scope of the claims.
