[0027] To make the purpose, technical solutions and advantages of the implementation of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the drawings in the embodiments of this application.

[0028] As Figure 1 and Figure 2 shown, this application provides a safety locking device applicable to safety locking and quick unlocking between devices. The safety locking device 10 includes a mounting base 1, a locking sleeve 2, a left fixing pin 3, a left hook body 4, a right fixing pin 5 and a right hook body 6.

[0029] In some embodiments of the present application, the body of the mounting base 1 has a rectangular structure, and the upper end of the body of the mounting base 1 is fixed on the lower mounting surface of the bearing structure 20. The lower part of the body of the mounting base 1 extends with a front bearing plate and a rear bearing plate. At the ends of the front bearing plate and the rear bearing plate, there are a front bearing plate boss 11 and a rear bearing plate boss 12 extending outward respectively. A through slot that completely penetrates horizontally is formed between the front bearing plate and the rear bearing plate. In some embodiments of the present application, both the front bearing plate boss 11 and the rear bearing plate boss 12 are rectangular bosses, and this through slot is a rectangular through slot.

[0030] The upper part of the left hook body 4 is a straight section, and the lower part of the left hook body 4 is an arc section. The left hook body 4 is arranged in the through slot of the mounting base 1. The end of the straight section of the left hook body 4 is connected to the mounting base 1 through a left fixing pin 3, so that the left hook body 4 can freely rotate around the left fixing pin 3 in the through slot of the mounting base 1.

[0031] Similarly, the upper part of the right hook body 6 is a straight section, and the lower part of the right hook body 6 is an arc section. The right hook body 6 is arranged in the through slot of the mounting base 1. The end of the straight section of the right hook body 6 is connected to the mounting base 1 through a right fixing pin 5, so that the right hook body 6 can freely rotate around the right fixing pin 5 in the through slot of the mounting base 1.

[0032] The left hook body 4 and the right hook body 6 are arranged symmetrically left and right on the mounting base 1, and the two are symmetrical structures. When the left hook body 4 and the right hook body 6 lock the rope 30, the end face of the arc section of the left hook body 4 fits with the end face of the arc section of the right hook body 6, thus forming a closed structure.

[0033] In some embodiments of the present application, the cross-sections of both the left hook body 4 and the right hook body 6 are rectangular structures, so that the surfaces of the left hook body 4 and the right hook body 6 can be in planar contact with the through slot of the mounting base 1 and / or the locking sleeve 2.

[0034] In the preferred embodiment of the present application, the outer sides of the straight sections of the left hook body 4 and the right hook body 6 are flush with the outer surface of the mounting base 1.

[0035] The middle part of the locking sleeve 2 is provided with a through hole that penetrates up and down and adapts to the shape of the mounting base 1. In this embodiment of the present application, the shape of the locking sleeve 2 is a rectangular structure, and this through hole is a rectangular through hole. The locking sleeve 2 is sleeved on the mounting base 1 through this through hole, and the lower end of the locking sleeve 2 is limited by the front bearing plate boss 11 and the rear bearing plate boss 12 of the mounting base 1. At this time, the outer sides of the straight sections of the left hook body 4 and the right hook body 6 are in contact with the inner surface of the through hole of the locking sleeve 2.

[0036] When in use, when locking is required, first move the locking sleeve 2 upward to the upper part of the mounting base 1 so that the lower end of the locking sleeve 2 is higher than the left fixing pin 3 and the right fixing pin 5. Then open the left hook body 4 and the right hook body 6, place the rope 30 in the arc-shaped closed area of the left and right hook bodies, release the locking sleeve 2, and the locking sleeve 2 begins to slide downward under the action of gravity. The locking sleeve 2 squeezes the outer sides of the straight sections of the left and right hook bodies, so that the left and right hook bodies automatically close and lock, achieving the effect of quick locking.

[0037] When the locking of the rope 30 needs to be released, move the locking sleeve 2 upward to the upper part of the mounting base 12. Similarly, make the lower end of the locking sleeve 2 higher than the left fixing pin 3 and the right fixing pin 5. The locking sleeve 2 no longer restricts the opening of the left and right hook bodies. At this time, after simply pulling the rope 30, the left and right hook bodies can open freely, and the rope 30 is disengaged, thus realizing the quick release function of the rope 30.

[0038] The safety locking device provided by this application realizes the reliable closing and locking of the left and right hook bodies by setting the cooperation mode of the straight sections of the left and right hook bodies and the locking sleeve, and symmetrically squeezing the straight sections of the left and right hook bodies through the through holes of the locking sleeve. By utilizing the self-gravity of the locking sleeve, the locking sleeve is always located at the lower part of the mounting base, thus ensuring the reliable locking effect of the left and right hook bodies under external collision and vibration and other environments. This application integrates the safety locking in a simple device, reduces the cost, has high reliability, realizes the safety locking and quick unlocking between devices, and the device is simple, firm, easy to use, and not restricted by external conditions.

[0039] The above is only the specific implementation manner of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by this application should be covered within the protection scope of this application. Therefore, the protection scope of this application should be subject to the protection scope of the claims.
