Description

Mixing prevention

The present invention relates to a blend prevention device, and more specifically, is installed to slide transfer at the end of the faust to reduce the thickness of the operator to open and close the air ball by miniaturizing the operator by injecting gasoline in the gas inlet of the diesel vehicle to prevent mixing oil generation It is about a blend prevention device to make it.

In general, the lubricator is a device for injecting oil from the oil storage tank installed in the basement to supply oil through a hose, etc., which is an oil lubricator main body including the oil intake and various related mechanical devices therein, and the main body and It is composed of a nozzle that is connected by a hose to allow the fuel source to supply the oil sucked by the mechanical operation inside the main body to the fuel tank (not shown) of the vehicle. In addition, the main body is provided with a pump 120 that is operated by the driving force of the motor 100 as shown in Figure 1 to suck the oil from the underground oil storage tank.

The pump 120 is operated by the driving force of the motor 100 as described above, the transmission thereof is the motor pulley 110 and the pump pulley on the rotary shaft of the motor 100 and the rotary shaft of the pump 120, respectively. 130 is installed, and the belt 140 is connected therebetween to transmit the driving force of the motor 100 to the pump 120 by the belt transmission.

In addition, a flow meter 150 is installed at an upper side of the pump 120 to measure oil flowed from the pump 120, and a solenoid valve 180 is installed at an upper side of the flow meter 150. The solenoid valve 180 is installed to control the flow rate or to block the flow path, the inlet pipe 160 is connected to the flow meter 150 on one side of the solenoid valve 180, the other side The discharge pipe 170 is connected to the hose 200.

In addition, the lubricator 300 is provided with a fuel nozzle 320 to protrude in a spout form from the nozzle body 310 formed so that the oil supply source can be easily grasped by hand, as shown in FIG. 1B, through the hose 200. It is configured to discharge the oil flowing into the nozzle body 310 to the outside, the lower side of the nozzle body 310 is provided with a lever 330 by pulling and releasing the fuel supply source of the solenoid valve 180 It is configured to perform the opening and closing operation of the flow path by). In addition, the lubricator 300 is an automatic operation means for stopping the lubrication stroke at the completion of lubrication while allowing the refueling source to be continuously made without continually holding and pulling the lever 330 when refueling Is provided.

The automatic operation means to install a sensor 340 at the end of the fuel nozzle 320 of the nozzle body 310 to detect the oil level of the oil filled in the fuel tank (T) of the vehicle by the refueling stroke In addition, the lever 330 is fixed to the nozzle body 310 of the lever 330 in a pulled state or the latch 330 is released by an operation according to a detection signal by the detection sensor 340. The ruler sea section 350 is provided.

The lubricator configured as described above opens the flow path by the solenoid valve 180 by pulling the lever 330 in a state in which the lubrication nozzle 320 of the lubricator 300 is first inserted into the fuel tank T of the vehicle. At the same time, the motor 100 is driven by an operation command by a controller (not shown). Accordingly, the motor pulley 110 installed on the rotation shaft of the motor 100 rotates, and the rotational force of the motor pulley 110 is transmitted to the pump pulley 130 again by the belt 140 transmission to pump 120. Will be activated. As the pump 120 is operated as described above, the oil in the underground oil storage tank is sucked into the pump 120, and the sucked oil is metered through the flow meter 150 at the pump 120 while the solenoid valve 180 is operated. Flows into the inlet pipe 160. In addition, the oil flowing into the inlet pipe 160 is supplied to the nozzle body 310 through the solenoid valve 180 again through the discharge pipe 170 and the hose 200, and is supplied to the nozzle body 310. The discharged oil is discharged through the oil supply nozzle 320 of the nozzle body 310 to perform the oil supply stroke.

At this time, the fuel supply source performs continuous refueling operation without manual operation in the state of hanging the lever 330 on the rubbing. In this state, when the oil level in the fuel tank T of the vehicle continues to rise to reach the detection sensor 340 installed at the end of the oil supply nozzle 320 of the lubricator 300, the detection sensor 340 is a signal thereof The controller is sent to the controller, the controller receives the signal to give the operation command to the ruler / solver 350 to release the latch of the lever 330. Accordingly, as the flow path by the solenoid valve 180 is blocked, the operation of the related devices is stopped and the series of oil supply strokes is automatically stopped.

The conventional lubricator operating as described above can be divided into two types according to the fuel used, because it is divided into a diesel vehicle using diesel as fuel and a gasoline vehicle using gasoline as fuel.

In general, the fuel inlet of the diesel vehicle is made larger than the fuel inlet of the gasoline vehicle, so the oil tanker of the diesel vehicle cannot enter the fuel inlet of the gasoline vehicle, but on the contrary, the gasoline of the gasoline vehicle can enter the fuel inlet of the diesel vehicle. In addition, even if the gasoline vehicle, the gas tank is made larger than the gas tank of the vehicle that uses the normal gasoline as fuel (see Tico fuel tank). Also, in the case of jeep cars, gasoline vehicles and diesel vehicles are used in combination.

According to the type of the vehicle as described above, the appropriate gasoline is used, there is a problem that the gasoline filling machine is lubricated in a diesel vehicle in which the fuel inlet is largely formed by mistake of the gas source, and sometimes the fuel injected is discarded. After dismantling, there is a problem that the work of washing and drying the inside and removing the other fuel transferred to the fuel line of the vehicle is not only a problem, but also may cause damage to the internal combustion engine in severe cases.

Another problem is that after setting the fueling amount of the customer and filling the fuel inlet with the gas injector while simultaneously filling the other car due to the lack of work, the fuel is drained from the fuel inlet and the fuel is scattered on the floor. In addition to pollution, there was a problem of causing a large fire by static electricity.

In view of the above problems, as described in the Republic of Korea Patent Registration No. 451972 has been proposed a lubricator to prevent mixing, and also a lubricator to prevent mixing such as Korean Utility Model Registration No. 437277 has been proposed.

The method of preventing mixing in the lubricator of the Republic of Korea Patent No. 451972 is attached to the installation hole 62 of the operator 6, as shown in Figure 2 of the soft pad member (4) of the installation hole 62 A protective plate 8 is installed at an upper portion and below the pad member 5 to protect the pad member 5. The pad member 5 is disposed on the outer circumferential surface of the operator 6. The fixing plate 9 which is fixed with bolts is fixedly installed so as not to be separated from the installation hole 62. On the other hand, the elastic member 10 is installed between the fixing plate 9 and the protective plate (8).

Meanwhile, as a method of preventing mixing in the lubricator of the Korean Utility Model Registration No. 437277, the sliding body 200 sliding along the guide groove 110 of the spout 100 toward the front side or the rear side as shown in FIG. The guide protrusion 210 is provided on the inner surface corresponding to the guide groove 110, and the through hole 220 is formed at a position corresponding to the air inlet hole 13h.

On the other hand, the opening and closing means 300 is installed on the outside of the sliding body 200, the structure of the opening and closing means 300 is a close contact spring 310 is installed in the through-hole 220 of the sliding body 200, the contact spring ( The coupling plate 312 fixed to one end of the 310, the contact pad 320 is fixed to one side of the coupling plate 312 in close contact with the outer surface of the spout 100, the outer side of the sliding body 200 Fitted is configured to include a protective cover 330 for supporting the other side of the close contact spring 310 and protect the sliding body 200.

In the conventional anti-mixing device having the structure as described above, the conventional anti-mixing device used in the lubricator of Korean Patent Registration No. 451972 has an operator 6 as a single part, but the pad 4 in the installation hole 62. Since the protective plate 8 and the elastic member 10 are installed, there is a problem in that the thickness of the operator becomes thick and the size of the operator becomes large.

The lubricator of the Republic of Korea Utility Model Registration No. 437277 is made of a sliding body 200 constituting the operator and a protective cover 330 installed on the outside has a problem that the size of the operator becomes even larger.

Therefore, in order to prevent blending as described above, a blender with a blending prevention function is used, but in the case of a jeep car, for example, a gasoline vehicle and a diesel vehicle are used in combination, and a part of a jeep and an imported car and an operator at a periphery of a gas inlet of a diesel vehicle Tico, etc., which are made larger than a gas inlet of a vehicle using ordinary gasoline as a fuel, may not use a gas tank having a blending prevention function or may cause an operator to be jammed because an operator is caught in the periphery of the gas inlet.

The present invention devised in view of the above-described conventional problem is to provide a mixing prevention tool that can improve the reliability of the lubricator product by forming a smaller size of the operator to operate the mixing prevention function accurately.

The object of the present invention is a mixture prevention tool for opening and closing the air inlet hole while the slide movement along the spout to be oiled, the guide means of the spherical ball or mood bolt is inserted into the guide groove of the spout and ; An operator provided with a fitting groove in which the guide means is installed and provided with an installation groove having a predetermined size inward and moving along the spout; A pad member inserted into the installation groove to open and close the air inlet hole while forming a curvature and a curvature of the outer surface of the spout; At the bottom of the pad member is characterized in that a plurality of elastic pieces to closely contact the pad member having the same curvature toward the spout by the mixing prevention member comprising an adhesive carbon member consisting of a plate-shaped body bent in the opposite direction of the pad member Is achieved.

Two installation grooves are formed to face each other, and a pad member is installed in one of the installation grooves on one side of the air inlet hole, and an adhesion groove member is installed in the installation groove on the opposite side.

The pad member is achieved by the oil mixture preventer characterized in that a part protruding from the installation groove, it is also achieved by the oil mixture preventer characterized in that the close elastic member is a coil spring.

The present invention is installed to slide transfer at the end of the faust is reduced in size by reducing the thickness of the operator opening and closing the air ball to obtain the effect of the lubricator having a general mixing prevention function and at the same time the operator is caught in the gas inlet of the diesel vehicle injecting gasoline It is possible to improve the reliability of the lubricator product by preventing mixed oil to occur.

Hereinafter, described in detail with reference to the accompanying drawings a preferred embodiment of the present invention.

Figure 4 is a cross-sectional view showing the structure of the mixing prevention device to which the technique of the present invention is applied and Figure 5 is an exploded perspective view showing the structure of the pad means and the contact elastic member, which is the main part of the present invention according to the air inflow while sliding along the spout Mixing prevention device (1) for opening and closing the ball (P2) to be oiled by the operator (20) of the guide means 10 of the spherical ball or mood bolt is inserted into the guide groove of the spout (P) ) In the fitting groove (21). The guide means 10 is a spherical ball, such as described in the Republic of Korea Patent Registration No. 451972, or a mood bolt, such as the Republic of Korea Utility Model Registration No. 437277 is known, the description of the structure and operation thereof will be omitted.

The fitting groove 21 is provided with an installation groove 22 formed in a predetermined size spaced apart from a predetermined interval and is inserted into the operator 20 and the installation groove 22 to move along the spout of the spout (P) A pad member 30 for opening and closing the air inlet hole P2 is formed while forming the curvature of the outer surface and the curvature thereof.

The pad member 30 is preferably made of a synthetic resin material having an elastic force. At the bottom of the pad member 30, a plurality of elastic pieces 41 which are in close contact with the pad member 30 toward the spout P while forming the same curvature are bent in the opposite direction of the pad member (30) 42 is a structure consisting of a close contact with the coalescing member (40).

Meanwhile, as shown in FIGS. 6 to 7, the installation grooves 22 are formed to face each other, but the pad member 30 is installed in the installation groove 22 of the air inlet hole and the pad member 30. Is preferably installed to protrude a part from the installation groove (22). The opposite installation grooves 22a may be used separately from the pad member 30 separately from the padding member 30, and as shown in FIG. 8, the close coupling member 40 may be coil coil ( It can also be changed to 40a).

The pad member 30 is installed to partially protrude from the installation groove 22 in order to facilitate the sealing of the air inlet hole, and due to the spacing between the spout and the operator 20 and mechanical machining errors. This is to make it easy to obtain the effect of opening and closing the air inlet hole even when the close elastic member 40 is reduced in elastic force while compensating for the generated gap.

Meanwhile, as shown in FIG. 8, when the pad member 30 and the close contact elastic member 40 are separately installed in the

installation grooves

22a and 22b formed in the operator, the center of the operator and the spout may be eccentric. As shown in FIG. 8, the coil spring 40a may be installed in the

installation grooves

22a and 22b in place of the close contact member 40.

Referring to the operation state of the inventors of the oil mixture prevention apparatus 1 of the present invention, as shown in FIG. 10, when a spout is inserted into a fuel inlet of a gasoline engine using a vehicle having a similar size to the outer diameter of the spout, the spout is inside the fuel inlet. At the same time, the operator 20 is restricted from being inserted by the vehicle body that forms the fuel inlet, that is, the panel.

At the same time the spout P is inserted into the fuel inlet, the operator 20 maintains the state in close contact with the vehicle body forming the fuel inlet. At this time, the user of the lubricator applies a force to fuel the spout P. When pushed into the inlet, the spout 2 penetrating the actuator 6 is pushed into the fuel inlet as the spring member 3 is compressed as shown in FIG. 10.

Then, since the vehicle body supports the operator 20, the operator 20 compresses the spring member. At this time, as described in the Republic of Korea Patent Registration No. 451972 to the inside of the operator 20, the guide means (10) by installing a guide means (10), such as a spherical ball or a mood bolt, such as the Republic of Korea Utility Model Registration No. 437277 By moving along the guide groove provided in the spout, the air inlet hole P2 is completely completed by preventing the center of the pad member 30 closing the air inlet hole P2 when the operator 20 moves linearly. In order to be able to close it.

If the pad member 30 having the same curvature as the outer diameter of the spout P is not detached because the body 42 of the close contact member 40 forms the same curvature as the pad member 30 when the slide moves. The pad member 30 is easily held on the outer surface of the sub spout P, and furthermore, a plurality of elastic pieces 41 are integrally formed on the body 42 of the close contact elastic member 40 so that the pad member ( 30) will be in close contact with the spout (P).

As shown in FIG. 11, two mounting

grooves

22 and 22a formed in the operator 20 are formed to face each other, and a pad member is disposed in the installation groove 22 at one air inlet hole. 30) is installed in the installation groove (22a) on the opposite side can be used to install the close contact member 40.

As the above-described installation of the close contact elastic member 40 and the pad member 30, which are installed in the

installation grooves

22 and 22a, as described above, the thickness of the operator 20 can be made thin, thereby miniaturizing. to be.

On the other hand, if the close contact with the adhesive member 40 and the pad member 30 as described above, respectively, as shown in the accompanying drawings, the center of the operator 20 and spout (P) does not coincide and have an eccentricity .

At the same time as the spout P is pushed into the fuel inlet and air is introduced into the air inlet hole P2 connected to the sensing sensor closed by the pad member 30, the air discharge hole installed inside the spout P is installed. When the air is discharged to P2, at this time, the sensor detects the air inflow and performs normal oiling in the same way as the normal oil service. The fuel is filled in the tank to close the air inlet P2. Shut off the oil is the same operation as a normal oiler.

However, the fuel tanker is refueling another vehicle while the fuel tanker is placed on the fuel inlet due to a user's mistake or lack of work, and when the gasoline escapes from the fuel inlet and leaves, the fuel injected through the tanker remains unchanged. In the present invention, the lubricator stops working.

In more detail, when the spout P in the retracted state of the operator 20 is pulled out of the fuel inlet, the operator 20 advances by the elastic force of the spring member S as long as the spout P is pulled out of the fuel inlet. do.

On the other hand, in the present invention, even if the gasoline vehicle to retract the air inlet hole (P2) to retract the operator 20 when the fueling in the vehicle is made larger than the gas inlet of the vehicle using a normal gasoline as fuel It can be opened, so that oiling (lubrication) is possible, so that the operator 20 can be artificially retracted and oiling is possible.

On the other hand, when the lubricator of the present invention is inserted into the fuel inlet of the diesel vehicle, since the operator 20 closing the spout P and the air injection hole P2 is inserted together into the fuel inlet, the normal oiling (lubrication) operation is performed. This prevents oil from being mixed and prevents mixing, thereby preventing damage caused by fuel waste and other fuels entering the internal combustion engine.
