Description

Car filler injector

The invention relates to a filler replenisher, especially a filler injector for vehicles.

The internal parts of the vehicle often have different fillers that must be added, such as injecting refrigerant into the air-conditioning system, or special sol such as evaporator, condenser, pipeline O-ring, rubber gasket, compressor center oil seal, etc. effect. The addition of this type of filler is usually carried out in the maintenance factory. The operator connects a larger barrel with an injection head. The barrel is filled with the filler to be added. When adding the filler, it must be pushed Or roll the larger cylinder to the side of the vehicle, because the space in the maintenance plant is often crowded and limited, and the internal space of the vehicle is small, so the operation is not convenient.

In view of the problems of the prior art, the inventor believes that there should be a vehicle filling agent injector, which includes a tank connected with an injection head through a connecting pipe, and a pressing valve is provided on the upper part of the tank. To restore, open and close the path of the filler in the tank into the connecting pipe; and a polygonal seat is fixed on the outer edge of the pressing valve member, and the pressing valve member is exposed upward from the center of the polygonal seat axially, and another A pressure cap, the pressure cap is sleeved on the outer edge of the polygonal seat and the upper part of the pressing valve, and the inner side of the pressure cap is provided with two limiting pieces that can be flatly attached to the two sides of the polygonal seat, and the The adjacent side of each limit piece is a swing space, so as to provide the elastic limit of each limit piece to the two sides of the polygon seat. In addition to the fact that the tank body is connected with the injection head through the connecting pipe, the present invention can achieve easy portability, and has greater mobility and operability for the filler of the vehicle. Furthermore, the inner side of the pressure cap is provided with two limit pieces that can be flatly attached to the two sides of the polygon seat, and the adjacent side of each limit piece is a swing space, so as to provide each limit piece with flexibility The two side surfaces of the polygon seat are elastically limited. Because the material is slightly elastic, the polygon seat can overcome the limitation of the two limiting pieces inside the pressure cap and form another limit of the steering angle under the external force rotation and compression. Therefore, the tank can have more turning space.

In the following, the structure, features and embodiments of the present invention will be explained through the cooperation of the drawings, so that your reviewer can have a better understanding of the present invention. Please refer to the first figure. The present invention relates to a vehicle filler injector, which includes a tank (1) connected with an injection head (3) via a connecting pipe (2). As shown in the fifth figure, the injection head (3) can be connected to the external vehicle parts pipeline (4) to provide filling agent. Please refer to the second figure. The tank (1) includes a pressing valve (31) on the upper part. By pressing and returning, the filler in the tank (1) enters the connecting pipe (2). Then through the injection head (3), it enters the needs of the car body, such as injecting refrigerant into the air-conditioning system, or such as evaporator, condenser, pipeline O-ring, rubber gasket, compressor center oil seal, etc. It can be filled with special sol to form a leak-trapping effect. A polygonal seat (32) is fixedly arranged on the outer edge of the pressing valve member (31), and the pressing valve member (31) is exposed upwards from the center of the polygonal seat (32); and a pressure cap (33) ), the pressure cap (33) is fixed on the tank body (1), and is sleeved on the outer edge of the polygonal seat (32) and above the pressure valve member (31), as shown in the third and fourth figures As shown, the inner side of the pressing cap (33) is provided with two limit pieces (331) that can be flatly attached to the two sides of the polygon seat (32), and the adjacent side of each limit piece (331) is a swing space (332), so as to provide the limit pieces (331) to elastically limit the two sides of the polygon seat (32). In addition to the fact that the tank body (1) is connected with the injection head (3) by the connecting pipe (2), the present invention can achieve easy portability, and has greater mobility and operability for vehicle fillers. Furthermore, the inner side of the pressure cap (33) is provided with two limit pieces (331) that can be flatly attached to the two sides of the polygon seat (32), and the adjacent sides of each limit piece (331) are a swing The space (332) provides the elasticity of each limiting piece (331) to the two side surfaces of the polygon seat (32). Because the material is slightly elastic, the polygon can be rotated and compressed by external force. The seat (32) overcomes the limitation of the two limiting pieces (331) inside the pressure cap (33), and forms a limit of another steering angle, so the tank body (1) can have a larger steering space. Please refer to the first figure, where the pressure cap (33) is fixed on the tank body (1), and the pressure cap (33) and the pressing valve member (31) share a pivot (34) in series connection , And the formation of easy assembly. Please refer to the second figure, where the path of the connecting pipe (2) is provided with a pressure gauge (21) to detect the pressure in the connecting pipe (2). In summary, the present invention is indeed in line with industrial applicability, has not been seen in publications or publicly used before the application, has not been known to the public, and is non-obvious and easy to know, and meets the requirements of patentability. A patent application is filed in accordance with the law . However, the above-mentioned report is a preferred embodiment in the industry of the invention, and all the equivalent changes made in accordance with the scope of the patent application of the invention belong to the scope of the claims of this case.
