[0003] In the prior art, such as the patent application CN202411227611.X entitled "A Quick Connector for Instruments in a Hydrogen-Powered Bus that is Easy to Install," a main connector is included, with a secondary connector on the top wall of the main connector, and a uniformly distributed first fixing sleeve fixedly connected to the inner wall of the main connector. In this invention, the socket and sliding seat are integrated. When the plug is pulled due to external force, the socket slides through the sliding seat within the first fixing sleeve, thereby compressing a strong spring, causing deformation and storing elastic energy. Simultaneously, the movement of the secondary connector pulls the connecting sleeve through a connecting plate, further moving the sliding seat within the first fixing sleeve. This provides space for the movement of the plug and socket, and the first strong spring releases the stored elastic energy, allowing the plug and socket to quickly return to their original positions. This prevents the plug from falling off, improves safety, and solves the problem in the prior art where the connector is prone to falling off during accidents or bumps.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1

[0023] like Figures 1-6As shown, this utility model provides a technical solution: a quick-connect anti-detachment device for hydrogen pipelines, including a hydrogen pipeline mechanism 1 and a connector mechanism 2. The hydrogen pipeline mechanism 1 is located at both ends of the connector mechanism 2. The connector mechanism 2 includes a rotating sleeve 201. The inner ends of the rotating sleeve 201 are threaded with anti-detachment components 204. One end of the anti-detachment component 204 has a plurality of evenly distributed locking claws 207. The hydrogen pipeline mechanism 1 includes a pipeline interface 101. The outer wall of the pipeline interface 101 is provided with a crimping ring 102. The locking claws 207 are all fastened to the outer side of the crimping ring 102 for quick connection and to provide anti-detachment fixation. The outer wall of the rotating sleeve 201 is provided with a rotating sleeve 201. The outer wall of the movable nut 202 is evenly distributed with several anti-slip ridges 203. The outer wall of the anti-detachment component 204 is provided with threaded openings 205 in different directions. Several sliding grooves 206 are opened on the anti-detachment component 204. A sleeve 209 is provided on the inner side of the anti-detachment component 204. Several guides 210 are evenly distributed at both ends of the outer wall of the sleeve 209. The sliding grooves 206 and the guides 210 are slidably connected. Several limiting strips 208 are evenly distributed on the outer wall of one end of the anti-detachment component 204. A positioning ring 211 is fixedly installed on the outer wall of the sleeve 209. The positioning ring 211 is movably connected to the inner wall of the rotating sleeve 201.

[0024] In this embodiment, a crimping ring 102 is integrally formed on the outer side of the pipe interface 101. Both ends of the pipe interface 101 are correspondingly inserted into the inside of the sleeve 209, realizing the initial docking between the pipe interface and the sleeve. Two sets of anti-detachment components 204 are symmetrically fitted on the outer wall of the sleeve 209. The outer wall of the anti-detachment component 204 is machined with a precision thread 205. The thread 205 meshes with the inner thread structure of the rotating sleeve 201 to form a stable threaded transmission connection. A rotating nut 202 is fixedly installed on the outer wall of the rotating sleeve 201. The outer surface of the rotating nut 202 is evenly distributed with anti-slip ridges 203. The operator can directly hold the rotating nut 202 manually and apply force. By turning the rotating nut 202, the rotating sleeve 201 can be driven to rotate synchronously. With the meshing transmission action of the thread 205, the two sets of anti-detachment components 204 can be driven to achieve bidirectional synchronous telescopic adjustment along the axial direction of the sleeve 209. The anti-detachment component 204 has an integrally formed locking claw 207 at its end. This locking claw 207 can precisely fasten onto the surface of the crimping ring 102 on the outside of the pipe interface 101, forming a firm locking and fixing structure. Through the precise cooperation between the locking claw 207 and the crimping ring 102, the pipe interface 101 and the sleeve 209 can be quickly inserted and removed without the need for additional auxiliary tools, significantly improving the efficiency of on-site installation and disassembly. The structural design of the locking claw 207 fastening the crimping ring 102 provides primary anti-detachment protection for the pipe connection. The overall device has a compact structure and occupies little space, making it suitable for various confined installation scenarios. Simultaneously, the anti-slip protrusions 203 on the outer surface of the rotating nut 202 effectively increase friction during operation, further improving the ease of operation for rotating and adjusting the rotating sleeve 201. In addition, the positioning ring 211 and guide 210 inside the sleeve 209 form a sliding fit structure through the sliding groove 206. This fit can effectively ensure the coaxiality accuracy of the pipe interface 101 and the sleeve 209 after connection, reduce the adverse effects of vibration generated during equipment operation on the connection part, and ensure the stability and reliability of the overall connection structure.

[0025] Example 2

[0026] like Figures 1-6 As shown, the connector mechanism 2 is provided with limiting mechanisms 3 at both ends. The limiting mechanism 3 includes a connecting plate 301. One end of the connecting plate 301 is fixedly connected to a limiting ring 302. The limiting ring 302 is movably sleeved on the outside of the anti-detachment component 204. The two ends of the rotating sleeve 201 are provided with insertion slots 303. The connecting plate 301 movably passes through the inside of the insertion slots 303. The top of the rotating sleeve 201 is symmetrically provided with positioning holes 304. The positioning holes 304 are connected to the inside of the insertion slots 303. The top of the rotating sleeve 201 is symmetrically provided with positioning holes 304. The positioning holes 304 are connected to the inside of the insertion slots 303. The limiting strip 208 is provided on the side of the limiting ring 302.

[0027] In this embodiment, the connecting plate 301 is assembled inside the insertion slot 303 using a sliding insertion connection method. Simultaneously, a limiting ring 302 is fitted onto the outside of the anti-detachment component 204, providing a stable and secure restraint effect for the anti-detachment component 204, thus achieving a dual-protection function of secondary anti-detachment. This structural design effectively prevents the anti-detachment component 204 from loosening or shifting under long-term use or external force, ensuring the overall connection reliability of the device. Furthermore, positioning holes 304 are provided at both ends of the rotating sleeve 201. Each positioning hole 304 forms a communication structure with the interior of the insertion slot 303. Positioning screws 305 are inserted and fixed inside the insertion slot 303, precisely locking and positioning the telescopic adjustment length of the connecting plate 301, significantly improving the structural stability and safety of the connecting plate 301 in different assembly states.

[0028] The working principle of this embodiment is as follows: First, the pipe interface 101 of the hydrogen pipeline mechanism 1 is precisely inserted into the sleeve 209 of the connector mechanism 2, ensuring that the crimping ring 102 at the end of the pipe interface 101 and the locking claw 207 on the anti-detachment component 204 are precisely aligned. Then, the rotating nut 202, with its outer surface having anti-slip protrusions 203, is manually rotated. The rotation of the nut 202 causes the rotating sleeve 201 to rotate synchronously. Through the meshing transmission action of the pre-set threaded opening 205 between the rotating sleeve 201 and the anti-detachment component 204, the anti-detachment component 204 is driven to move smoothly and linearly along the sliding groove 206 on the guide member 210 until the locking claw 207 on the anti-detachment component 204 is firmly engaged with the outer side of the crimping ring 102, completing the initial fixing operation of the hydrogen pipeline. After initial fixing, the connecting plate 301 of the limiting mechanism 3 is inserted into the pre-set insertion slot 303 on the side wall of the rotating sleeve 201 and slidably adjusted so that the limiting ring 302 at the end of the connecting plate 301 is stably fitted onto the outside of the anti-detachment component 204. Then, the positioning screws 305 are screwed into and pressed against the surface of the connecting plate 301 through the positioning holes 304 at both ends of the rotating sleeve 201, thereby locking the extension length of the connecting plate 301. Through the covering and limiting effect of the limiting ring 302, the axial displacement of the anti-detachment component 204 can be effectively restricted, preventing it from loosening due to external vibration or long-term use, thus achieving the anti-detachment reinforcement effect for the hydrogen energy pipeline. When it is necessary to disassemble the hydrogen energy pipeline, the operation steps are the reverse of the installation steps. First, unscrew the positioning screw 305 in the positioning hole 304, take out the connecting plate 301 and the limiting ring 302 of the limiting mechanism 3, and then rotate the rotating sleeve 201 in the opposite direction. Through the reverse transmission of the threaded end 205, the anti-disengagement part 204 is driven to reset along the sliding groove 206, so that the buckle claw 207 and the crimping ring 102 are released from the engagement state. At this time, the pipeline interface 101 can be easily pulled out from the sleeve 209 to complete the disassembly operation.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
