Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile fuel tank parts, and particularly relates to an automobile plastic fuel tank cap. Background Technique
[0002] A fuel container on an airplane or an automobile is a special container for storing hydraulic oil or hydraulic fluid in a hydraulic system. The fuel tank can be divided into two types: an open fuel tank and a closed fuel tank. An openable fuel tank cap is provided on the open fuel tank.
[0003] In the existing fuel tank, it is necessary to set the fuel tank cap and the fuel tank body as a split structure, which makes the fuel tank cap easy to lose after being opened. Most of them are connected to the fuel tank body through threads. When threaded, the threads on the fuel tank cap and the fuel tank body are both easy to adhere to oil. First, it causes waste of oil. Second, the oil on the threads is not easy to flow back and is easy to pollute the surfaces of the fuel tank and the fuel tank cap, making it difficult to clean the oil adhered to the fuel tank cap and the fuel tank, and making it easier to adsorb dirt.
[0004] Based on this, the utility model designs an automobile plastic fuel tank cap to solve the above problems. Content of the Utility Model
[0005] The purpose of the utility model is to provide an automobile plastic fuel tank cap, so as to provide a snap-on anti-loss fuel tank cap that can automatically return the oil in the fuel tank cap to the fuel tank.
[0006] To achieve the above purpose, the utility model provides the following technical solutions:
[0007] An automobile plastic fuel tank cap includes an installation cover body. A connecting rod is fixedly installed at the inner top of the installation cover body. A hydraulic sensor is fixedly installed at the lower end of the connecting rod. A lower inclined cover is fixedly installed at the lower end of the installation cover body. A lower positioning member is fixedly installed at the lower end of the lower inclined cover. A plurality of rubber strips are fixedly installed on one side of the lower positioning member away from the lower inclined cover. An elastic rod is fixedly installed on the lower positioning member corresponding to the lower side of the rubber strip. An elastic ball is fixedly installed at one end of the elastic rod away from the lower positioning member. A connecting pipe is fixedly installed on one side of the lower positioning member.
[0008] Preferably, a liquid accumulation groove is arranged in the lower positioning member. The connecting pipe is communicated with the liquid accumulation groove. One end of the connecting pipe away from the lower positioning member is fixedly connected to the fuel tank body.
[0009] Preferably, an upper fixing block is fixedly installed on the upper surface of the installation cover body. A plurality of anti-slip strips are fixedly installed on the outer side of the installation cover body.
[0010] Preferably, an inner concave arc cover is fixedly installed on the top of the installation cover body, the lower edge of the inner concave arc cover is smooth, and the inner side wall of the installation cover body is also smooth.
[0011] Preferably, the hydraulic sensor is introduced to the bottom of the fuel tank, the elastic member is an elastic plate, and both the elastic member and the elastic ball can abut against the outer wall of the upper end of the fuel tank.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] When the oil adheres to the upper end of the inner wall of the installation cover body of the present utility model, the oil will slide along the inner concave arc cover to the side wall of the installation cover body, and then slide along the side wall into the liquid accumulation tank. After accumulating a certain amount, the accumulated oil will flow back to the fuel tank through the connecting pipe, which can effectively reduce the waste of oil, avoid the contamination of the fuel tank and the surface of the fuel tank cap caused by the gaps of the oil threads in the case of threaded connection, and the connecting pipe connects the installation cover body and the fuel tank to prevent the loss of the installation cover body when it is opened.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] Please refer to Figures 1-4 , the present invention provides a technical solution:
[0023] An automotive plastic fuel tank cap, including an installation cover body 1, a connecting rod 5 is fixedly installed on the inner top of the installation cover body 1, a hydraulic sensor 6 is fixedly installed at the lower end of the connecting rod 5, a lower inclined cover 2 is fixedly installed at the lower end of the installation cover body 1, a lower positioning member 4 is fixedly installed at the lower end of the lower inclined cover 2, a plurality of rubber strips 11 are fixedly installed on one side of the lower positioning member 4 away from the lower inclined cover 2, an elastic rod 12 is fixedly installed on the lower positioning member 4 corresponding to the lower side of the rubber strip 11, an elastic ball 13 is fixedly installed at the end of the elastic rod 12 away from the lower positioning member 4, and a connecting pipe 7 is fixedly installed on one side of the lower positioning member 4.
[0024] Wherein, a liquid accumulation groove 14 is arranged in the lower positioning member 4, the connecting pipe 7 is communicated with the liquid accumulation groove 14, and the end of the connecting pipe 7 away from the lower positioning member 4 is fixedly connected to the fuel tank body.
[0025] Wherein, an upper fixing block 8 is fixedly installed on the upper surface of the installation cover body 1, and a plurality of anti-slip strips 3 are fixedly installed on the outer side of the installation cover body 1.
[0026] Wherein, an inner concave arc cover 9 is fixedly installed on the top of the installation cover body 1, the lower edge of the inner concave arc cover 9 is smooth, and the inner side wall of the installation cover body 1 is also smooth.
[0027] Wherein, the hydraulic sensor 6 is led to the bottom of the fuel tank, the elastic member 10 is an elastic plate, and both the elastic member 10 and the elastic ball 13 can abut against the outer wall of the upper end of the fuel tank.
[0028] In the present utility model, the installation cover main body 1 is sleeved on the filling nozzle of the fuel tank. The lower inclined cover 2 and the lower positioning member 4 at the lower end of the installation cover main body 1 are arranged at the lower end of the fuel tank filling nozzle, and the elastic member 10 and the elastic rod 12 are clamped on the upper side of the fuel tank. Limiting grooves are provided on the fuel tank corresponding to the positions of the elastic member 10 and the elastic rod 12. The rubber strip 11 on the elastic member 10 can increase the friction force between the elastic member 10 and the outer wall of the fuel tank, thereby increasing the installation firmness of the installation cover main body 1. Moreover, the hydraulic sensor 6 at the bottom of the connecting rod 5 extends to the bottom of the fuel tank. When the liquid level at the bottom of the fuel tank is lower than the hydraulic sensor 6, the hydraulic sensor 6 can warn about the usage condition of the fuel tank. When oil adheres to the upper end of the inner wall of the installation cover main body 1, the oil will slide along the concave arc cover 9 to the side wall of the installation cover main body 1, and then slide into the liquid accumulation groove 14 along the side wall. After accumulating a certain amount, the accumulated oil will flow back into the fuel tank through the connecting pipe 7, which can effectively reduce oil waste and avoid the situation where the gaps in the oil thread contaminate the surfaces of the fuel tank and the fuel tank cap in the case of threaded connection. In addition, the connecting pipe 7 connects the installation cover main body 1 and the fuel tank, preventing the installation cover main body 1 from being lost when opened.
