[0017] Please see Figure 1-3A quick-install automotive pipe fitting connecting nut includes an automotive pipe fitting connecting nut body 1. A set of limiting components 2 are symmetrically arranged on the surface of the automotive pipe fitting connecting nut body 1. The automotive pipe fitting connecting nut body 1 includes a nut base 101, a nut base 2 102 attached to one side of the nut base 101, and a set of threaded arc frames 103 symmetrically engaged inside the nut base 101 and nut base 2 102. A set of guide blocks 104 are symmetrically fixed on the outer surface of the set of threaded arc frames 103. A screw 105 is fixedly connected to the side of the guide block 104 away from the threaded arc frame 103. Guide grooves 106 are opened inside both the nut base 101 and the nut base 2 102. The threaded arc frames 103 and the guide grooves 106 form an engaging structure through the guide blocks 104. The screw 105 passes through the guide grooves 106, and a limiting ring 107 is screwed onto the outside of the screw 105. Furthermore, the threads of the two threaded arc frames 103 are connected. Two threaded arc brackets 103 form a detachable structure with nut base 101 and nut base 2 102 respectively, through screw 105 and limiting ring 107. The split design of the automotive pipe fitting connecting nut body 1 allows for quick insertion into the pipe fitting, greatly simplifying the traditional installation process that requires screwing in the entire nut and significantly improving assembly efficiency. The threaded arc bracket 103 is quickly positioned in the nut base through the cooperation between guide block 104 and guide groove 106, and then fixed by the cooperation between screw 105 and limiting ring 107. This achieves a detachable connection between the threaded arc bracket 103 and the nut base, and can flexibly adapt to different specifications of automotive pipe fittings, greatly improving the convenience of installation and disassembly. At the same time, the split design facilitates later maintenance and parts replacement. When the threaded arc bracket 103 is worn or damaged, it is not necessary to replace the entire automotive pipe fitting connecting nut body 1; only the corresponding parts need to be replaced, which significantly reduces the cost of use and maintenance.

[0018] The limiting assembly 2 includes a first limiting frame 201, which is symmetrically fixed to one side of the surface of the nut base 101. A second limiting frame 202 engages between the first limiting frames 201.

One end of the spring 204 near the opening of the inner groove 203 is connected to a locking block 205. The first limiting frame 201 has a locking groove that matches the end of the locking block 205. The locking block 205 forms an elastic structure with the inner groove 203 via the spring 204. When the spring 204 is in its normal state, one end of the locking block 205 is engaged in the groove. The locking block 205 is cylindrical, and an extension rod 206 is fixedly connected to its side surface. A sliding groove 207 is fitted to the outer side of the extension rod 206, and a protective plate 208 is fixedly sleeved on the outer side of the extension rod 206. Furthermore, the extension rod 206 forms a locking and sliding structure with the second limiting frame 202 via the sliding groove 207. When the spring 204 is in its normal state... The protective plate 208 can completely cover the outer opening of the slide groove 207. Through the elastic force of the spring 204 in the inner groove 203, the cylindrical locking block 205 and the locking groove of the limiting frame 1 201 are precisely matched and engaged, which can quickly realize the positioning and fixing of the nut base 1 101 and the nut base 2 102, effectively preventing relative displacement between the two during the connection of the pipe fittings, and ensuring the stability of the overall connection structure. The extension rod 206 fixed to the side surface of the locking block 205 and the sliding groove 207 form a locking and sliding structure, which is a locking mechanism. The telescopic movement of block 205 provides guidance and limitation, and the engagement state of block 205 and slot can be easily released by moving extension rod 206, which facilitates the disassembly and maintenance of nut components later. The protective plate 208 on the outside of extension rod 206 can completely cover the outer opening of slide groove 207 when spring 204 is in normal state, which can effectively prevent external dust, impurities and other things from entering the inner groove 203, avoid jamming or corrosion of core components such as spring 204 and block 205, and extend the service life of limit component 2.
