[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An anti-fall protection device that is easy to install, comprising a rigid guide rail, a housing assembly, and a pair of locking assemblies symmetrically arranged on both sides of the rigid guide rail;

[0008] The housing assembly includes a first housing and a pair of second housings that are detachably connected. The cross-section of the first housing is in the shape of a concave character, and the cross-section of the second housing is in the shape of a ┌ character. A pair of inclined slide holes are opened on one side of the first housing, and the positions of the second housings corresponding to the slide holes are also opened with slide holes.

[0009] The locking assembly is slidably connected to the slide slot hole and is used to change the distance between the locking assembly and the rigid guide rail.

[0010] Preferably, the pair of slide slot holes are arranged in a V-shape.

[0011] Preferably, the locking assembly comprises a guide post and a locking block, and the guide post is provided with a threaded section near both ends;

[0012] The two ends of the guide column respectively pass through the slide slot holes of the first shell and the second shell, and the threaded sections at both ends are threadedly connected to two sliders, wherein the two sliders close to the locking block are respectively in contact with the inner side portions of the first shell and the second shell, and the remaining two sliders away from the locking block are respectively in contact with the outer side portions of the first shell and the second shell;

[0013] The locking block is connected to the guide column, and an arc-shaped groove that matches the shape of the rigid guide rail is opened on the outer periphery of the locking block.

[0014] Preferably, the cross section of the slider is circular, and the radius of the cross section is greater than the width of the chute hole.

[0015] Preferably, an anti-slip pad is provided on the inner side of the arc-shaped groove.

[0016] Preferably, it further comprises a plurality of rope threading rings, wherein the rope threading rings are connected to the outer side of the outer slider.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the solution of the present utility model, the first shell and a pair of second shells are detachably connected to form a shell assembly. During installation, the guide column passes through the slide slot holes of the first shell and the second shell respectively, and the threads at both ends of the guide column are threadedly connected to the slider to position the first shell and the second shell outside the rigid guide rail. This design achieves the purpose of rapid disassembly and assembly of the anti-fall device.

[0019] 2. The utility model cooperates with the locking component and a pair of "V"-shaped slide slot holes, and the rope loop is connected to the safety rope worn by the height worker. When the height worker slips and falls, the locking component moves downward rapidly with the safety rope, and at this time the outer shell component will maintain its original state due to inertia. At this time, the pair of locking components move closer to the rigid guide rail. After falling to a certain position, the arc groove of the locking block will clamp the rigid guide rail, thereby achieving the purpose of preventing falling. In addition, with the assistance of the anti-slip pad, the friction force during locking is increased, preventing the locking component from accidentally slipping, and enhancing the stability of the device.

A pair of inclined slide holes 23 are provided on one side of the first shell 21, and a pair of slide holes 23 are also provided at positions corresponding to the slide holes 23 in the second shells 22; specifically, the pair of slide holes 23 are arranged in a "V" shape.

[0032] The locking assembly 3 is slidably connected to the slide slot hole 23 to change the distance between the locking assembly 3 and the rigid guide rail 1 .

[0033] Furthermore, the locking assembly 3 includes a guide column 31 and a locking block 33, and the guide column 31 is provided with a threaded section near both ends;

[0034] The two ends of the guide column 31 pass through the slide slots 23 of the first shell 21 and the second shell 22 respectively, and the threaded sections at both ends are threadedly connected to two sliders 32. The two sliders 32 close to the locking block 33 are respectively in contact with the inner side of the first shell 21 and the second shell 22, and the remaining two sliders 32 away from the locking block 33 are respectively in contact with the outer side of the first shell 21 and the second shell 22;
