[0023] like Figure 1-Figure 3As shown, this specific embodiment adopts the following technical scheme: it comprises a locking ring 1, a connecting block 2 and a blocking rod 3, both ends of the opening of the locking ring 1 are fixedly provided with connecting blocks 2, a blocking rod 3 is provided between the two connecting blocks 2, the connecting block 2 is movably provided in a movable opening 4 opened at the end of the blocking rod 3, a wear-resistant pad 12 is provided on the inner top wall of the locking ring 1, which can effectively reduce the wear caused between the locking ring 1 and the locked force-bearing object, and reinforcing ribs 14 are fixedly provided on the front and rear side walls of the locking ring 1, and the reinforcing ribs 14 can improve the structural strength of the locking ring 1, so that its force-bearing performance can be enhanced;

[0024] It also contains:

[0025] A rotating shaft 5, wherein the rotating shaft 5 is movably inserted into the lower connecting block 2, and the end of the rotating shaft 5 is fixedly connected to the stop rod 3, a No. 1 torsion spring 6 is movably sleeved on the rotating shaft 5, one end of the No. 1 torsion spring 6 is connected to the inner wall of the lower connecting block 2, and the other end of the No. 1 torsion spring 6 passes through the lower connecting block 2 and is fixedly inserted into the stop rod 3;

[0026] A limiting sleeve 7, wherein the limiting sleeve 7 is sleeved on the stop rod 3 through a bearing screw connection, and an adapter 8 matching with the connecting block 2 is provided on both the front and rear sides of the side wall of the end of the limiting sleeve 7, and an anti-skid pattern 13 is provided on the ring side wall of the limiting sleeve 7, and the anti-skid pattern 13 can improve the roughness of the surface of the ring side wall of the limiting sleeve 7, so that when the staff rotates by hand, a larger friction force can be generated between the limiting sleeve 7 and the hand, thereby reducing the occurrence of hand slippage. An annular groove is provided on the side wall of the stop rod 3, and a rubber pad 15 is fixedly provided on the inner side wall of the locking ring 1, which can prevent the end of the limiting sleeve 7 from directly contacting the inner side wall of the locking ring 1 and causing wear;

[0027] A second torsion spring 9, wherein the second torsion spring 9 is movably sleeved on the annular groove, and the two ends of the second torsion spring 9 are respectively connected to the side wall of the annular groove and the inner wall of the limiting sleeve 7, and the limiting sleeve 7 is connected to the connecting block 2 through a limiting connection mechanism 18;

[0028] The position limiting connection mechanism 18 comprises:

[0029] The limiting connecting strips 10 are two and are respectively fixedly arranged on the front and rear side walls of the upper movable opening 4, and the limiting connecting strips 10 are movably clamped in the limiting clamping grooves 16 opened on the side walls of the upper connecting block 2;

[0030] The reinforcement connecting strips 11 are four in number and are respectively fixedly arranged on the upper and lower sides of the front and rear inner side walls of the limiting sleeve 7 , and the reinforcement connecting strips 11 are movably clamped in the connection clamping grooves 17 opened on the side walls of the connection block 2 .

[0031] When using the utility model, the limiting sleeve 7 is rotated to make the adapter port 8 correspond to the connecting block 2, and the No. 2 torsion spring 9 is twisted, and then the upper end of the limiting sleeve 7 is pressed toward the inner side of the locking ring 1, so that the blocking rod 3 rotates around the rotating shaft 5 as the axis, and the No. 1 torsion spring 6 is twisted, and at the same time, the upper connecting block 2 will be disengaged from the movable port 4, and the limiting connecting strip 10 will also be disengaged from the limiting slot 16, and then the locking ring 1 can be hooked to the outer force-bearing rod, and then the limiting sleeve 7 is released, so that the No. 1 torsion spring 6 is reset to drive the rotating shaft 5 to rotate in the opposite direction, and the rotating shaft 5 drives the blocking rod 3 to rotate to the opening of the locking ring 1, so that the upper side The connecting block 2 is re-impeded into the movable opening 4, and the limiting connecting strip 10 is also stuck in the limiting slot 16, which not only limits the position of the blocking rod 3, but also realizes the connection between the upper end of the blocking rod 3 and the upper connecting block 2. At the same time, the No. 2 torsion spring 9 will be reset, driving the limiting sleeve 7 to rotate in the opposite direction, so that the adapter port 8 and the connecting block 2 are staggered, thereby realizing the self-locking limit of the position of the blocking rod 3, and the limiting sleeve 7 will drive the reinforcement connecting strip 11 to be stuck in the connecting slot 17, thereby realizing the connection between the limiting sleeve 7 and the upper and lower connecting blocks 2. At this time, in the overall force-bearing process of the safety lock, the limiting sleeve 7 can share the force exerted on the blocking rod 3.

[0032] After adopting the above structure, the beneficial effects of this specific implementation are as follows:

[0033] 1. Through the cooperation of the limiting sleeve 7, the second torsion spring 9, the limiting connecting strip 10 and the reinforcing connecting strip 11, not only the self-locking function of the safety lock can be realized, making the operation process simpler and safer, but also the force of the blocking rod 3 can be shared, thereby improving the force bearing performance of the lock;

[0034] 2. The anti-slip pattern 13 can improve the roughness of the side wall surface of the limiting sleeve 7, so that when the staff rotates the limiting sleeve 7 by hand, a greater friction force can be generated between the limiting sleeve 7 and the hand, reducing the occurrence of the phenomenon of difficulty in rotating the limiting sleeve 7 due to hand slippage.

[0035] For those skilled in the art, they can modify the technical solutions recorded in the aforementioned embodiments and make equivalent substitutions for some of the technical features.
