[0018] The first embodiment of the present application is:

[0019] See also Figure 1-Figure 3 , Figure 1 It is a structural schematic diagram of the utility model. Figure 2 It is a transverse cross-sectional view of the utility model along the pull rod direction. Figure 3 It is a transverse sectional view of the utility model along the direction of the connecting strip, including a braking part 101, an extension part 102 and a locking assembly, the locking assembly includes a fixing bolt, a connecting strip 103 and a pull rod, the connecting strip 103 has a through slot 104; the pull rod includes a slide bar 105 and a spring 106, the fixing bolt includes a fixing bolt body 107 and a knob 108. The above scheme solves the problem that the fall arrester cannot be deployed and needs to be installed from the notch at the bottom or top of the T-shaped guide rail, which is inconvenient to use. It can be understood that the above scheme can be used in the scenario of high-altitude work protection.

[0020] According to this specific embodiment, the pull rod is slidably connected to the braking part 101 and is fixedly connected to the extension part 102 and is located between the extension part 102 and the braking part 101. The connecting strip 103 is detachably connected to the braking part 101 and is fixedly connected to the extension part 102 and is located between the extension part 102 and the braking part 101. The fixing bolt is threadedly connected to the braking part 101 and passes through the braking part 101. When the fall arrester is installed, the user first rotates the fixing bolt with the hand to separate the fixing bolt from the connecting strip 103, and then pulls the extension part 102 with the hand to separate the extension part 102 from the braking part 101, thereby extending the width of the fall arrester. While the extension part 102 moves, the pull rod and the connecting strip 103 are also pulled out of the braking part 101 together, and then the extension part 102 is expanded. The rear fall arrester is placed on the guide rail, the extension part 102 is loosened, and the pull rod is reset to drive the extension part 102 to reset, so that the extension part 102 and the braking part 101 are against the guide rail from both sides. When the extension part 102 is reset, the connecting strip 103 is inserted into the braking part 101. At this time, the user rotates the fixing bolt in the opposite direction and inserts the fixing bolt into the through groove 104 on the connecting strip 103, thereby completing the installation operation of the fall arrester. The connecting strip 103 has a plurality of through holes, so that the fall arrester can be applied to guide rails of different widths, thereby improving the practicality of the fall arrester. The fall arrester does not need to be installed from the top or bottom notch of the guide rail, but can be installed from any position of the guide rail. Compared with the traditional fall arrester, the installation operation is more convenient and quick, which solves the problem that the fall arrester cannot be unfolded and needs to be installed from the notch at the bottom or top of the T-shaped guide rail, which is inconvenient to use.

[0021] Among them, the sliding rod 105 is slidably connected to the braking part 101, and is fixedly connected to the extension part 102, and is located between the extension part 102 and the braking part 101. The spring 106 is fixedly connected to the sliding rod 105, and is fixedly connected to the braking part 101, and is located between the sliding rod 105 and the braking part 101. The sliding rod 105 slides out in the braking part 101 to guide the extension part 102 to avoid that when the extension part 102 is pulled out or reset, the connecting strip 103 cannot be smoothly inserted into the braking part 101, thereby affecting the installation efficiency of the fall arrester. The spring 106 is set to pull the sliding rod 105 to reset, thereby driving the extension part 102 to reset.

[0022] Secondly, the fixing bolt body 107 is threadedly connected to the braking part 101 and passes through the braking part 101. The knob 108 is fixedly connected to the fixing bolt body 107 and is located on the side of the fixing bolt body 107 away from the braking part 101. The fixing bolt body 107 is inserted into the through groove 104 of the connecting strip 103 and is clamped and fixed with the connecting strip 103 to realize the assembly of the fall arrester. The setting of the knob 108 makes it convenient for the user to rotate the fixing bolt body 107.

[0023] When installing the fall arrester, the user first turns the knob 108 by hand, and the rotation of the knob 108 drives the fixing bolt body 107 to brake, so that the fixing bolt body 107 is separated from the connecting strip 103, and then pulls the extension part 102 by hand to separate the extension part 102 from the braking part 101, thereby extending the width of the fall arrester. When the extension part 102 moves, the sliding rod 105 and the connecting strip 103 are also pulled out of the braking part 101, and the spring 106 is in a stretched state. Then place the expanded fall arrester on the guide rail, loosen the extension part 102, and the spring 106 is reset, so that the slide bar 105 is reset and drives the extension part 102 to reset, so that the extension part 102 and the braking part 101 are against the guide rail from both sides. While the extension part 102 is reset, the connecting strip 103 is inserted into the braking part 101. At this time, the user rotates the knob 108 in the opposite direction to insert the fixing bolt body 107 into the through groove 104 on the connecting strip 103, thereby completing the installation operation of the fall arrester.

[0024] The second embodiment of the present application is:

[0025] Based on the first embodiment, please refer to Figure 4 , Figure 4 20 is a schematic diagram of the structure of the utility model. The rail-type fall arrester of the embodiment also includes an auxiliary component, and the auxiliary component includes a first pull ring 201, a second pull ring 202 and a limit ring 203.

[0026] According to this specific embodiment, the auxiliary component is arranged on one side of the braking portion 101 and the extension portion 102. The auxiliary component is arranged to assist the user in using the fall arrester.

[0027] Among them, the first pull ring 201 is fixedly connected to the braking part 101 and is located at one side of the braking part 101, the second pull ring 202 is slidably connected to the extension part 102 and is located at one side of the extension part 102, the limiting ring 203 is fixedly connected to the braking part 101 and is located at a side of the braking part 101 close to the fixing bolt body 107, the setting of the first pull ring 201 and the second pull ring 202 makes it convenient for the user to pull apart the extension part 102 and the braking part 101, and the setting of the limiting ring 203 prevents the user from rotating the fixing bolt body 107 out of the braking part 101 and causing it to fall off.

[0028] When the auxiliary component is in use, the user holds the first pull ring 201 and the second pull ring 202 with hands, and pulls the extension part 102 and the braking part 101 to both sides, thereby separating the extension part 102 and the braking part 101, and limits the fixing bolt body 107 by the limiting ring 203 to prevent the user from rotating the fixing bolt body 107 out of the braking part 101 and causing it to fall off.

[0029] The above disclosure is only a preferred embodiment of a rail-type fall arrester of the present application, and cannot be used to limit the scope of rights of the present application.
