Description

Technical Field

[0001] This utility model relates to the field of guide rail devices, and in particular to a rigid anti-fall guide rail device. Background Technology

[0002] Rigid fall arrestor rails are devices used to ensure the safety of workers at heights. They mainly consist of guide rails, a steering mechanism, and a self-locking device. The guide rails are usually made of rigid materials and are the main supporting structure of the device. The steering mechanism is mainly used to connect the vertical and horizontal rigid guide rails and can change the direction of movement of the self-locking device on the guide rail. When the self-locking device is in normal operation, the latch retracts and the self-locking device can slide in the guide rail. When a person accidentally falls, the latch will quickly extend and lock onto the rail surface, using gravity and friction between the latch and the guide rail surface to quickly lock the person in place, thus providing fall protection.

[0003] In existing technologies, multiple guide rails are typically connected together during actual use of guide rail devices. If a large number of guide rails need to be connected, multiple connectors are required. However, the guide rails themselves do not have connecting parts, so additional connectors need to be carried. If not enough connectors are carried or connectors are forgotten, it may affect the connection of the guide rails, which is quite inconvenient. Therefore, a rigid anti-fall guide rail device is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a rigid anti-fall guide rail device, which adds a docking structure to the guide rail body, thereby eliminating the need to carry additional connecting parts and avoiding the problem of insufficient connecting parts affecting the subsequent work.

[0005] To achieve the above objectives, a rigid fall arrestor guide rail device is provided, comprising a guide rail, two recessed blocks fixedly connected to the guide rail, two guide rods fixedly connected to the inner surface of the guide rail, springs slidably sleeved on the outer surfaces of the two guide rods, first limiting blocks slidably connected to the outer surfaces of the two guide rods, movable blocks fixedly connected to the side surfaces of the two first limiting blocks, two bearing blocks fixedly connected to the guide rail, second limiting blocks slidably connected to the inner surfaces of the two bearing blocks, connecting blocks fixedly connected to the side surfaces of the two second limiting blocks, sliders fixedly connected to the side surfaces of the two connecting blocks, first threaded rods fixedly connected to the side surfaces of the two second limiting blocks, nuts threadedly connected to the outer surfaces of the two first threaded rods, and second threaded rods fixedly connected to the side surfaces of the two sliders.

[0006] According to the rigid anti-fall guide rail device, the movable block is provided with a positioning hole, which is adapted to the second threaded rod.

[0007] According to the rigid anti-fall guide rail device, a limiting groove is formed on the bearing block, and the outer surface of the first threaded rod is slidably connected to the limiting groove.

[0008] According to the rigid anti-fall guide rail device, a sliding groove is provided on the bearing block, and the outer surface of the second limiting block is slidably connected to the sliding groove.

[0009] According to the rigid anti-fall guide rail device, the outer surface of the connecting block is slidably connected to the bearing block, and the side surface of the nut is in contact with the bearing block.

[0010] According to the rigid anti-fall guide rail device, the guide rail is provided with an anti-detachment groove, and the outer surface of the first limiting block is slidably connected to the anti-detachment groove.

[0011] According to the rigid anti-fall guide rail device, one end of the spring is fixedly connected to the side surface of the first limiting block, and the end of the spring away from the first limiting block is fixedly connected to the inner side wall of the guide rail.

[0012] According to the rigid anti-fall guide rail device, the outer surface of the movable block is slidably connected to the guide rail, and the nut is adapted to the second threaded rod.

[0013] The above-mentioned solution has the following beneficial effects:

[0014] By incorporating a support block, a second limiting block, a connecting block, and a slider, this solution adds a docking structure to the guide rail body, eliminating the need for additional connecting parts and preventing subsequent work from being affected by insufficient connecting parts.

[0015] The recessed block provides positioning for the movement of structures such as sliders. When the moving slider engages with the recessed block, the positioning hole aligns with the second threaded rod, eliminating the need for operators to align the positioning hole with the second threaded rod and increasing operator convenience.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-5This utility model embodiment of a rigid anti-fall guide rail device includes a guide rail 1, with two recessed blocks 2 fixedly connected to the guide rail 1. Two guide rods 3 are fixedly connected to the inner surface of the guide rail 1. Springs 4 are slidably sleeved on the outer surfaces of both guide rods 3. First limiting blocks 5 are slidably connected to the outer surfaces of both guide rods 3. Movable blocks 6 are fixedly connected to the side surfaces of both first limiting blocks 5. One end of the spring 4 is fixedly connected to the side surface of the first limiting block 5, and the end of the spring 4 away from the first limiting block 5 is fixedly connected to the inner side wall of the guide rail 1. Under the action of the spring 4... The guide rail 1 is equipped with a mechanism that allows the first limiting block 5 and the movable block 6 to move and reset quickly. Two bearing blocks 8 are fixedly connected to the guide rail 1. Second limiting blocks 9 are slidably connected to the inner surfaces of both bearing blocks 8. Connecting blocks 10 are fixedly connected to the side surfaces of both second limiting blocks 9. Slider blocks 11 are fixedly connected to the side surfaces of both connecting blocks 10. First threaded rods 12 are fixedly connected to the side surfaces of both second limiting blocks 9. Nuts 13 are threadedly connected to the outer surfaces of both first threaded rods 12. Second threaded rods 14 are fixedly connected to the side surfaces of both sliders 11. The movable block 6 has a positioning hole 7, which is adapted to the second threaded rod 14. Through the reserved positioning hole 7, the first limiting block 5, movable block 6 and other structures can move smoothly to reset. The bearing block 8 has a limiting groove 15, and the outer surface of the first threaded rod 12 is slidably connected to the limiting groove 15. The bearing block 8 has a sliding groove 16, and the outer surface of the second limiting block 9 is slidably connected to the sliding groove 16. Under the action of the limiting groove 15 and the sliding groove 16, the second limiting block 9, connecting block 10, slider 11, first threaded rod 12 and second threaded rod 14 can move smoothly to reset. The structure can move smoothly. The outer surface of the connecting block 10 is slidably connected to the bearing block 8. The side surface of the nut 13 is in contact with the bearing block 8. The guide rail 1 is provided with an anti-detachment groove 17. The outer surface of the first limiting block 5 is slidably connected to the anti-detachment groove 17. The outer surface of the movable block 6 is slidably connected to the guide rail 1. The nut 13 is adapted to the second threaded rod 14. When the nut 13 is unscrewed from the first threaded rod 12, it can be directly screwed onto the second threaded rod 14 for use in subsequent fixing work without the need to carry other connecting parts.

[0027] Working principle: By using a wrench or similar tool to rotate the nut 13, the nut 13 is unscrewed from the first threaded rod 12, thereby releasing the fixation of the first threaded rod 12, the second limiting block 9, the connecting block 10, the slider 11, and the second threaded rod 14. Then, the corresponding ends of the sliders 11 and the concave blocks 2 on the two guide rails 1 are brought together. The first threaded rod 12 is then pushed, causing the first threaded rod 12, the second limiting block 9, the connecting block 10, the sliders 11, and the second threaded rod 14 to move. During the movement of the sliders 11, the movable block 6 is pulled, allowing the moving movable block 6 to drive the first limiting block 5 to move on the guide rod 3. This ensures that the moved movable block 6 is not affected by the second threaded rod 14, thus preventing the movement of the sliders 11 from being hindered. Furthermore, during the movement of the first limiting block 5, it gradually compresses the spring 4, thus keeping the spring 4 in a taut state. When the moving slider 11 contacts and fits together with the concave block 2, the slider 11 aligns with the positioning hole 7 on the movable block 6. At this time, the movable block 6 is released, so that the spring 4 is no longer compressed and rebounds. The rebounding spring 4 drives the first limiting block 5, the movable block 6, and the positioning hole 7 to move. At this time, through the positioning hole 7 reserved on the movable block 6, the movable block 6 can be smoothly reset and inserted into the second threaded rod 14. Then, the nut 13 is screwed back onto the second threaded rod 14 and tightened. Then, the above operation is repeated at other locations to achieve the docking between the two guide rails 1. To dock more guide rails 1, the above operation is repeated multiple times.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
