DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] like Figure 1-2 As shown, the utility model provides a climbing safety ring that is not easy to fall off from the foot nails, and its length is adjustable, and it is not easy to fall off from the foot nails. The safety ring provided in this embodiment includes a reel 1 and a steel strand 2. The reel 1 is provided with a buckle 3 through a hanging rope, and the buckle 3 is connected to the belt around the waist of the staff, so that the reel 1 is fixedly hung on the staff. In this embodiment, the steel strand 2 is located in the reel 1, one end of which is connected to the front end of the spiral spring 102 in the reel 1, and the other end is extended to the outside of the reel 1 after wrapping around the spiral spring 102 for multiple turns. The reel 1 can reel the steel strand 2. By controlling the length of the steel strand 2 extending outside the reel 1, the overall length of the safety ring can be changed, making it more convenient to use.

[0020] It should be emphasized here that the reel 1 is an existing device, which mainly includes a reel housing 101, a spiral spring 102 arranged inside the reel housing 101, a fixed shaft 103 for fixing the position of the spiral spring 102, and a lock 104 arranged at the outlet of the reel housing 101 and used to lock the position of the steel strand 2. The settings of the above components are all existing technologies and will not be described in detail here.

[0021] In the utility model, in order to enable the end of the steel strand 2 extending to the outside of the winder 1 to be hung on the foot nail, a wire pressing tube 4 is provided on the steel strand 2, and the wire pressing tube 4 is a double-hole wire clamping tube. After the steel strand 2 passes through the two hole clamps of the double-hole wire clamping tube in turn, it is fixedly connected with the two hole clamps. It needs to be emphasized here that the fixed connection here refers to flattening the double-hole wire clamping tube, so that the double-hole wire clamping tube is fixed on the steel strand 2, and the steel strand 2 is fixedly connected to itself to form a ring 201 that can be hung on the foot nail.

[0022] In order to prevent the ring 201 from easily falling off the foot nail, the present embodiment is also provided with an anti-slip semicircular ring 10, the ring 201 is fixedly sleeved on the outer circle side of the anti-slip semicircular ring 10, and the inner circle sides of the anti-slip semicircular ring 10 are hinged with splints 6 at both ends, the splint 6 is composed of a hinge part 601 and an arc-shaped clamping part 602 arranged at the upper end of the hinge part 601, the inner arcs of the two arc-shaped clamping parts 602 relatively form a clamping space for clamping the foot nail, and the two hinge parts 601 are relatively inclined upward to form a conical channel for the foot nail to enter the clamping space, and an extrusion spring 7 is provided between the splint 6 and the inner circle side of the anti-slip semicircular ring 10, and the extrusion spring 7 is arranged at one end of the hinge part 601 close to the arc-shaped clamping part 602.

[0023] After the foot nail enters the collar 201, the conical channel makes it easier for the foot nail to enter the clamping space. The extrusion force applied by the extrusion spring 7 can squeeze the foot nail entering the clamping space. The friction force generated by the extrusion makes it difficult for the collar 201 to move easily on the foot nail, so that it is not easy to fall off. At the same time, the size of the clamping space is determined by the pressure applied by the extrusion spring 7, which can be changed and can be applied to foot nails of different specifications and thicknesses, so that the safety ring has a wider range of applications.

[0024] In this embodiment, both ends of the inner circle side of the anti-dropping semicircular ring 10 are provided with hinge seats 5, and the lower end of the hinge portion 601 is hinged to the hinge seat 5. The arrangement of the arc-shaped clamping portion 602 makes it difficult for the foot nail located between the two arc-shaped clamping portions 602 to fall out of the anti-dropping semicircular ring 10.

[0025] In this embodiment, in order to improve the friction of the arc-shaped clamping portion 602, an anti-skid rubber pad is embedded on the inner arc side of the arc-shaped clamping portion 602. Anti-skid particles can also be evenly arranged on the inner arc side of the arc-shaped clamping portion 602 to also improve the friction.

[0026] In this embodiment, in order to fix the ring 201 on the outer circle side of the anti-slip semicircular ring 10, a plurality of limiting semicircular rings 8 are provided on the outer circle side of the anti-slip semicircular ring 10, and a passage for the steel strand 2 to pass through is formed between the limiting semicircular rings 8 and the outer circle side of the anti-slip semicircular ring 10. The end of the steel strand 2 extending to the outside of the reel 1 first passes through the passage and is then clamped with the double-hole wire clamp.

[0027] At the same time, in order to facilitate the knotting of the ring 201 and the fixation of the limiting semicircular ring 8, connecting parts 11 are provided at both ends of the limiting semicircular ring 8, and the connecting parts 11 are provided with connecting holes for the bolts 9 to pass through. The outer circle side of the anti-slip semicircular ring 10 is provided with threaded holes corresponding to the connecting holes one by one, and the studs of the bolts 9 can be screwed into the threaded holes after passing through the connecting holes.

[0028] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various modifications or variations within the scope of the claims, which does not affect the essence of the present invention.
