Description

Technical Field

[0001] This utility model relates to the technical field of safety protection equipment for high-altitude operations, and specifically to a safety belt fixing device for high-altitude operations. Background Technology

[0002] Working at height refers to work performed in locations where there is a risk of falling 2 meters or more from the ground. It is widely used in construction, equipment installation, exterior wall cleaning, and power maintenance. Working at height enables the efficient completion of tasks difficult to access from the ground, improving construction efficiency and ensuring the smooth progress of infrastructure construction and maintenance. However, the environment at height is complex and carries the risk of falls; therefore, reliable safety protection devices, such as safety belts and their securing devices, must be provided to ensure the safety of workers.

[0003] Currently, the fixing devices for safety belts used in high-altitude operations mainly adopt hook or buckle structures. Traditional hook locking mechanisms rely on a single spring, which is prone to fatigue failure after long-term use, posing a risk of accidental disengagement. Secondly, when traditional hooks use threaded locking, although the hook will not disengage, it is inconvenient to hook and unhook. In addition, traditional hooks are only hook structures and lack status warning functions, making it difficult to quickly confirm the locking status and provide external warnings at night or in low-light environments. Utility Model Content

[0004] The purpose of this utility model is to provide a safety belt fixing device for high-altitude operations. By improving the hook structure, optimizing the locking mechanism, and adding a ring light strip, it solves the problems of easy slippage, troublesome hooking and unhooking, and poor visibility in the existing technology.

[0005] The technical solution provided by this utility model is a safety belt fixing device for high-altitude operations, including a hook body and a locking block. The hook body is generally in the shape of a J-shape, and a connecting part for fixing the safety belt is connected to its bottom. An opening is provided between the head of the hook body and the connecting part. A ring light strip and a magnet are symmetrically arranged on both sides of the connecting part. A fixing groove for connecting the safety belt is provided at the bottom of the connecting part. The connecting part is located on the side of the opening and is slidably connected to the locking block through a guide groove. A guide rod that is slidably connected to the locking block is vertically arranged inside the guide groove, and a compression spring is sleeved on the outside.

[0006] As a preferred technical solution of this utility model, the outer side of the hook body is wrapped with an anti-slip sleeve, and the hook body is coated with an anti-wear indicator layer.

[0007] As a preferred embodiment of this utility model, the magnet is located at the middle of the inner side of the annular light strip, and the annular light strip is connected to a battery on the inner side of the connecting part.

[0008] As a preferred embodiment of this utility model, the connecting part is provided with a battery slot for placing a storage battery, and a battery cover is provided on the side of the battery slot opposite to the guide plate. A switch button for control is provided above the battery cover on the connecting part.

[0009] As a preferred embodiment of this utility model, the guide groove is a dovetail groove structure, the guide rod is at the same height as the guide groove, the height of the guide groove is greater than the height of the opening, and the height of the locking block is greater than the height of the opening.

[0010] As a preferred technical solution of this utility model, the locking block is T-shaped, and the width of the locking block is less than or equal to the thickness of the connecting part. The top of the locking block is provided with a downwardly inclined guide surface at the point where it abuts the hook body.

[0011] As a preferred technical solution of this utility model, the locking block has an overall T-shaped structure located on both sides of the guide surface to form an auxiliary pressing platform, and multiple anti-slip grooves are symmetrically provided on both sides of the locking block.

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] 1. This safety belt fixing device uses a T-shaped locking block driven by a compression spring to cooperate with the hook body to form a mechanical interlock, preventing accidental opening. The design of the lever and anti-slip groove facilitates one-handed operation, making it easy to open the opening of the hook body for hooking or removing. At the same time, the dovetail-shaped guide groove ensures the stability of the locking block's movement.

[0014] 2. This safety belt fixing device provides nighttime illumination and warning through a ring-shaped light strip, which can remind you of the position of the hook and enhance safety at night or in harsh environments. It also provides an indication of the wear level of the anti-slip sleeve and the hook body through the anti-wear indicator layer. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Example 1:

[0024] As per the instruction manual Figure 1-4 As shown, a safety belt fixing device for high-altitude operations includes a hook body 1 and a locking block 2. The hook body 1 has an overall J-shaped structure, and a connecting part 3 for fixing the safety belt is connected to its bottom. An opening 4 is provided between the head of the hook body 1 and the connecting part 3. The outside of the hook body 1 is covered with an anti-slip sleeve 11, and the anti-slip sleeve 11 has multiple anti-slip textures distributed in a circumferential direction. The hook body 1 is coated with an anti-wear indicator layer 12.

[0025] In this utility model, the connecting part 3 is symmetrically provided with annular light strips 5 and magnets 6 on both sides. The magnets 6 are located in the middle of the inner side of the annular light strips 5, and the annular light strips 5 are connected to the battery 13 on the inner side of the connecting part 3. The connecting part 3 is provided with a battery slot 14 for placing the battery 13. A battery cover 15 is provided on the side of the battery slot 14 opposite to the guide plate. A switch button 16 for control is provided on the connecting part 3 above the battery cover 15.

[0026] In this utility model, the bottom of the connecting part 3 is provided with a fixing groove 7 for connecting the safety belt. The connecting part 3 is located on one side of the opening 4 and is slidably connected to the locking block 2 through the guide slide 8. The guide slide 8 is a dovetail groove structure. The guide rod 9 is the same height as the guide slide 8. The height of the guide slide 8 is greater than the height of the opening 4. The height of the locking block 2 is greater than the height of the opening 4. The locking block 2 is T-shaped in general. The width of the locking block 2 is less than or equal to the thickness of the connecting part 3. The top of the locking block 2 is provided with a downwardly inclined guide surface 17 where it abuts against the hook body 1.
