The second limiting groove includes a second vertical section, and one end of the second vertical section facing the bottom of the connection groove is communicated with a second horizontal section. The second section is embedded into the second horizontal section to limit the movement of the support ring.

[0008] Furthermore, a limiting ring is arranged on the connecting rod, and the limiting ring can abut against the support ring to limit the support ring from detaching from the connecting rod.

[0009] Further, a plurality of first ratchet teeth are provided on the support ring, and second ratchet teeth that cooperate with the first ratchet teeth are provided on the end face of the second connecting portion so that the support ring can rotate unidirectionally.

Detailed Embodiments

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0019] Refer to Figures 1 to 4, a lock rod structure, comprising a rod body 100 and a lock rod head 110. The rod body 100 includes a first connecting portion 200, and the lock rod head 110 includes a second connecting portion 300. The first connecting portion 200 is provided with a connecting rod 210, and the second connecting portion 300 is provided with a connecting groove 310 for the connecting rod 210 to insert. An end portion of the connecting rod 210 is provided with a first limiting rod 211, the first limiting rod 211 is perpendicular to the connecting rod 210, and a side wall of the connecting groove 310 is provided with a first limiting groove 311 for the first limiting rod 211 to insert. The first limiting groove 311 includes a first vertical section 312, and one end of the first vertical section 312 facing the bottom of the connecting groove 310 is communicated with a first horizontal section 313.

[0020] When the connecting rod 210 is inserted into the connecting groove 310, the first limiting rod 211 moves along the first vertical section 312 to the connection between the first vertical section 312 and the first horizontal section 313. The rotation of the connecting rod 210 drives the first limiting rod 211 to move into the first horizontal section 313, thereby restricting the connecting rod 210 from being pulled out of the connecting groove 310, and fixing the connection between the rod body 100 and the lock rod head 110.

[0021] A support ring 220 is sleeved on the connecting rod 210. The support ring 220 can move along the connecting rod 210. At the same time, a limiting ring 212 is provided on the connecting rod 210, and the support ring 220 and the limiting ring 212 can abut against each other, so that the limiting ring 212 restricts the support ring 220 from disengaging from the connecting rod 210. A plurality of second limiting rods 230 are provided on a surface of the support ring 220 facing the second connecting portion 300. The second connecting portion 300 is provided with a support groove 320, and a side wall of the support groove 320 is provided with a second limiting groove 330 cooperating with the second limiting rods 230. Specifically, the second limiting rods include a first section 231 extending along the axial direction of the rod body 100, an end portion of the first section 231 is provided with a second section 232 perpendicular to the first section 231, and the second section 232 extends outward. The second limiting groove 330 includes a second vertical section 331, and one end of the second vertical section 331 facing the bottom of the connecting groove 310 is communicated with a second horizontal section 332. The second section 232 first moves along the second vertical section 331. After moving to the connection between the second vertical section 331 and the second horizontal section 332, the support ring 220 is rotated to embed the second section into the second horizontal section 332, thereby restricting the movement of the support ring 220.

[0022] At the same time, a plurality of first ratchet teeth 221 are provided on the support ring 220, and a second ratchet tooth 340 cooperating with the first ratchet teeth 221 is provided on an end face of the second connecting portion 300 so that the support ring 220 can rotate in one direction. A spring 240 is provided between an end face of the first connecting portion 200 and the support ring 220, and the spring 240 is sleeved on the connecting rod 210. The spring 240 can push the first ratchet teeth 221 to engage with the second ratchet teeth 340.

[0023] During assembly, insert the connecting rod 210 into the connecting groove 310 and rotate the rod body 100, so that the connecting rod 210 drives the first limiting rod 211 to rotate, and then the first limiting rod 211 is embedded into the first horizontal section 313, connecting the rod body 100 with the locking rod head 110. At the same time, the second section 232 of the second limiting rod 230 also extends along the second vertical section 331 of the second limiting groove 330 to the connection between the second vertical section 331 and the second horizontal section 332. Under the action of the spring 240, the first ratchet wheel meshes with the second ratchet wheel to limit the rotation direction of the support ring 220. After the support ring 220 rotates, the second section 232 is embedded into the second horizontal section 332 to enhance the structural strength. At the same time, due to the cooperation of the first ratchet wheel and the second ratchet wheel, the support ring 220 cannot rotate in the reverse direction, enabling the second section 232 to remain embedded in the second horizontal section 332.
