[0012] Furthermore, the top of the buckle is flat, and the top of the buckle fits into the bottom of the subway body.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the connection cable, which is easy to install quickly, enables easy and quick disassembly and assembly;

[0014] When connecting to the subway body, the self-locking rod is connected to the through holes at both ends. During connection, the push rod is pressed down to move it down in the telescopic groove. The push rod drives the push head to contact the inner protrusion of the buckle, causing the buckles on both sides to retract inward, allowing the self-locking rod to pass smoothly through the through hole. Then, the push rod is released, and the spring returns to its original position, causing the support base to move upward and push the buckle to unfold again, quickly and securely connecting it to the bottom of the subway body. Finally, the nut is rotated to reinforce the subway body and the self-locking rod, improving assembly and disassembly efficiency, greatly saving labor, and increasing practicality and flexibility.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Please see Figures 1-5 The present invention provides an embodiment of a subway connector that is easy to install quickly, comprising a subway connector body 1 and a through hole 2, wherein the upper and lower ends of the subway connector body 1 are provided with through holes 2.

[0024] The through hole 2 is internally connected to a self-locking rod 7, and the self-locking rod 7 is internally connected to a push rod 5;

[0025] An external thread 4 is provided on the outer side of the top of the self-locking rod 7. A nut 3 is connected to the outer thread of the external thread 4. An anti-slip strip is provided on the outer side of the nut 3, and the anti-slip strip is made of rubber.

[0026] Specifically, such as Figure 3 and Figure 5 As shown, during use, the external thread 4 on the outer side of the top of the self-locking rod 7 can reinforce and limit the self-locking rod 7 and the connecting body 1, extending the service life of the self-locking rod 7 and the connecting body 1. The anti-slip strip on the outer side of the nut 3 can increase the friction and facilitate disassembly and assembly.

[0027] The self-locking rod 7 has an internal telescopic groove 14;

[0028] The width of the telescopic groove 14 matches the width of the push head 13;

[0029] Specifically, such as Figure 4 As shown, when in use, by setting the width of the telescopic groove 14 to match the width of the push rod 5, the connection strength can be improved, stress concentration can be reduced, and service life can be extended.

[0030] Push heads 13 are fixed to the bottom ends of both sides of the self-locking rod 7. The bottom end of the push head 13 is connected to the support base 12, and the bottom end of the support base 12 is connected to the push rod 11. The bottom end of the self-locking rod 7 is provided with a receiving groove 8. The outside of the push rod 11 is connected to a spring 10, and the bottom end of the spring 10 is fixed to the bottom end of the receiving groove 8. The two sides of the self-locking rod 7 are connected to hinge joints 9, and the outside of the hinge joints 9 is provided with buckles 6.

[0031] There are two sets of buckles 6. The buckles 6 are symmetrical about the central axis of the push rod 5. The top of the buckles 6 is flat and fits against the bottom of the subway body 1.

[0032] Specifically, such as Figure 3 As shown, in use, by setting two sets of buckles 6 with the top of the buckles 6 being flat and fitting with the bottom of the main body 1 of the subway, the stability of the structure can be enhanced, the contact area can be increased, the installation difficulty can be reduced, and the inspection can be made easier.

[0033] Working principle: When using this utility model, firstly, when connecting to the subway body 1, the self-locking rod 7 is connected to the through holes 2 at both ends. During connection, the push rod 5 is pressed down to move the push rod 5 down in the telescopic groove 14. The push rod 5 drives the push head 13 to contact the inner protrusion of the buckle 6, so that the buckles 6 on both sides retract inward, allowing the self-locking rod 7 to pass smoothly through the through hole 2. Then, the push rod 5 is released, and the spring 10 returns to its original position in the receiving groove 8, causing the support seat 12 to move up and push the buckle 6 to unfold again, so that it is quickly and securely connected to the bottom end of the subway body 1. Then, the nut 3 is rotated to reinforce the subway body 1 and the self-locking rod 7.
