Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vehicle assembly joint accessories, in particular to a stainless steel quick-insert female joint. Background Art
[0002] The quick-connect female connector is a commonly used pipe connection accessory in the automobile pipe system. It can be easily connected with the male connector to achieve the connection of the pipe. One end of the quick-connect female connector is a pipe connection part, which is used to connect with the pipe, and the other end is a joint part, which is used to connect with the male connector.
[0003] Existing quick-connect female connectors are processed by one-piece stretching. This processing method will result in a thinner inner wall thickness of the female connector. When the connecting pipe is connected to the pipeline by buckling, the connecting pipe is easily deformed under pressure, which will cause liquid or gas leakage in the pipeline, which may easily cause vehicle failure.
[0004] To this end, we have designed and developed a new type of stainless steel quick-plug female connector, which changes the traditional one-piece stretch-formed connector processing form. The connecting pipe part and the connecting pipe part are stretched separately and then welded together, which can effectively increase the wall thickness of the connecting pipe part so that it is not affected by the connecting pipe part, allowing the connecting pipe part to withstand the buckling pressure and avoid the problems of easy deformation of the connecting pipe and easy leakage of the pipeline after connection.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1
[0021] See also Figure 1-7This embodiment provides a stainless steel quick-insert female connector, including a connector portion 1 and a connecting portion 2, wherein the connector portion 1 and the connecting portion 2 are connected by welding. Figure 1 as well as Figure 3 As shown, after the joint portion 1 is connected to the connecting portion 2, a welding ring 3 is formed at the connection.
[0022] like Figure 1 , Figure 2 , Figure 6 as well as Figure 7 As shown, a retaining ring 5 is rotatably arranged at the top of the inner side of the joint part 1, and a plurality of spring retaining plates 6 inclined toward the inner side of the joint part 1 are evenly arranged on the upper end of the retaining ring 5. Preferably, four spring retaining plates 6 are designed, and the shape of the spring retaining plates 6 is a conventional general shape familiar to technical personnel in this field, and this application will not elaborate on the limitation; wherein, in actual application, the retaining ring 5 and the spring retaining plates 6 are integrally processed and formed.
[0023] like Figure 1 , Figure 2 , Figure 4 as well as Figure 5 As shown, a pressure cap 7 is movably provided at the upper end of the joint part 1, which is used to release the limit of the spring blocking piece 6 on the male joint; specifically, a retaining ring 9 is provided on the inner wall of the top of the joint part 1, and a plurality of connecting plates 10 located inside the joint part 1 are evenly provided at the bottom of the pressure cap 7, and the connecting plates 10 are spaced apart from the spring blocking piece 6. In the present application, four connecting plates 10 are also correspondingly provided, and a locking tooth 11 corresponding to the retaining ring 9 is provided on the connecting plate 10; it should be noted that the connecting plate 10 should be an elastic member. In actual applications, as a conventional setting, the pressure cap 7, the connecting plate 10 and the locking tooth 11 are integrally processed and formed, and are preferably made of plastic.
[0024] It should be noted that, in practical applications, a limit ring should be placed on the pressing cap 7 to limit the pressing cap 7 from pressing down into the connecting pipe 2, so that the pressing cap 7 will not easily press the spring stopper 5, thereby ensuring the stability of the connection between the connecting pipe 2 and the male connector.
[0025] In addition, as a conventional setting, in order to ensure the sealing performance after the joint is connected, a plurality of sealing rings 8 are arranged on the inner wall of the joint part 1.
[0026] When in use, the connector part 1 is buckled and connected to the pipeline, and the connecting part 2 is plugged into the male connector. This connection method is the same as the existing conventional female connector connection method, and this application will not repeat it. When the connection between the connecting part 2 and the male connector needs to be disconnected, it is only necessary to remove the limiting ring on the pressing cap 7 and press the pressing cap 7 downward. The pressing cap 7 presses the spring blocking piece 6 to move closer to the inner wall of the connecting part 2, so that the spring blocking piece 6 can release the limit of the male connector and the male connector can be pulled out.
[0027] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and technical features of the present application. For those skilled in the art, solutions or features that belong to the prior art or common knowledge are not described in detail in the above embodiments.
[0028] In addition, the technical solutions of the present application are not limited to the above-mentioned embodiments. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
