Detailed implementation manners

[0020] In order to enable those skilled in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the attached drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present application.

[0021] Refer to the attached drawings of the specification Figure 1-2As shown in the figure, a quick-detachable anti-slip chain includes a first side chain 1 and a second side chain 2. There are several transition chains 3 between the first side chain 1 and the second side chain 2. At one end point on the same side of the first side chain 1 and the second side chain 2, there are a second M-piece 4 and a fixing piece 5. A clamping block 5a is rotatably connected to the fixing piece 5. At the other ends of the first side chain 1 and the second side chain 2, there is a quick disassembly and assembly component 10. The quick disassembly and assembly component 10 includes: a fixing piece 101 and a plastic connecting piece 103. A connecting chain 102 is provided between the fixing piece 101 and the plastic connecting piece 103. A clamping groove 101c is provided inside the fixing piece 101. A positioning block 106a is provided adjacent to the clamping groove 101c. The positioning block 106a is fixedly connected to a pulling rope 106. One end of the fixing piece 101 is provided with a hook 101a, and the hook 101a is fixedly connected to the second side chain 2. Two ends of the plastic connecting piece 103 are respectively provided with a second chain link 104 and a connecting ring 105. One end of the plastic connecting piece 103 is connected to the first side chain 1 through the connecting ring 105 and the second M-piece 4. Among them, the quick disassembly and assembly component 10 includes a fixing piece 101 and a plastic connecting piece 103. A connecting chain 102 is provided between the fixing piece 101 and the plastic connecting piece 103. A clamping groove 101c is provided inside the fixing piece 101. A positioning block 106a is provided adjacent to the clamping groove 101c. The positioning block 106a is fixedly connected to a pulling rope 106. The clamping block 5a rotatably connected to the fixing piece 5 on the second side chain 2 cooperates with the positioning block 106a for fixation. By pulling the pulling rope 106 to drive the positioning block 106a, the clamping block 5a is loosened, and then the disassembly is completed.

[0022] Refer to the attached drawings of the specification Figure 3 As shown in the figure, when the pulling rope 106 is pulled, the pulling rope 106 drives the positioning block 106a to move in the direction of the pulling rope 106. The positioning block 106a does not contact the clamping block 5a. Then, the clamping block 5a can be disengaged from the fixing piece 101, and the disassembly of one end of the anti-slip chain is completed, which is convenient for disassembly.

[0023] As a preferred implementation manner of this embodiment, the connecting chain 102 includes a first plastic pipe 101a. On both sides of the first plastic pipe 101a, there are mutually connected first chain links 102d. A connecting iron block 102b is provided between the first chain links 102d. A second plastic pipe 102c is provided on the outer side of the first plastic pipe 101a to ensure the strength of the connecting chain.

[0024] Specifically, one end of the pulling rope 106 away from the positioning block 106a passes through the first plastic pipe 102a and extends to the outside of the plastic connecting piece 103. And a plastic buckle 107 is also provided on the pulling rope 106, which is convenient for pulling the pulling rope 106 to complete the disassembly of the anti-slip chain.

[0025] As another preferred implementation manner of this embodiment, a spring 106b is provided at the connection between the drawstring 106 and the positioning block 106a. The spring 106b can ensure that the positioning block 106a always abuts against the direction of the latch 5a, so that the latch 5a will not easily fall off from the fixing member 101 without pulling the drawstring 106.

[0026] Specifically, the second side chain 2 includes a steel wire rope 9, and a plurality of short plastic blocking tubes 7 and long plastic blocking tubes 8 are provided on the outer side of the steel wire rope 9.

[0027] In addition, a locking device 6 is provided on the first side chain 1.
