Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a retractable safety ladder for building construction. Background Technology

[0002] In the construction process, ladders play a vital role as a commonly used auxiliary tool. They help workers quickly and easily reach heights to perform various tasks, such as equipment installation, maintenance, repair, and cleaning.

[0003] However, although ladders are an indispensable tool for working at heights, existing ladders have certain limitations in their design, especially for the needs of continuous high-altitude operations.

[0004] Because most ladders use fixed-length treads, workers' movement space while operating on the ladder is restricted, easily leading to discomfort and safety hazards. This is especially true for larger workers, who may not receive sufficient comfort and support, increasing the risk of loss of balance or falls and adding to their discomfort. Therefore, a retractable safety ladder for construction is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a retractable safety ladder for building construction, which aims to solve the problem that workers' activity space is restricted when operating on the ladder in the prior art, which can easily lead to discomfort and safety hazards.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A retractable safety ladder for construction includes a main pole with two symmetrically arranged main poles. A telescopic assembly is provided between the two sets of main poles. The telescopic assembly includes a sleeve pole, and two symmetrically arranged sliding rods are slidably connected inside the sleeve pole. The sliding rods are fixedly connected to the side wall of the main pole. The side wall of the main pole has a sliding groove, and a sliding plate is slidably connected inside the sliding groove. A traction plate is hinged to the surface of the sliding plate, and the end of the traction plate is hinged to the side wall of the sleeve pole. The side wall of the sliding plate has a locking groove.

[0008] As a further description of the above technical solution:

[0009] The main rod has a positioning assembly on its side wall. The positioning assembly includes a threaded rod, one end of which is rotatably connected to the side wall of the main rod, and the other end of which is fixedly connected to a rotating wheel. A movable plate is threadedly connected to the outer wall of the threaded rod, and a locking block is fixedly connected to the side wall of the movable plate.

[0010] As a further description of the above technical solution:

[0011] The side wall of the slide rod is fixedly connected to a limiting post, and the side wall of the sleeve rod is provided with a limiting groove, with the limiting post slidably connected inside the limiting groove.

[0012] As a further description of the above technical solution:

[0013] The main rod has a through groove on its side wall for the locking block to pass through, and the locking block is inserted into the inner wall of the groove.

[0014] As a further description of the above technical solution:

[0015] The side wall of the movable plate has a through hole, and a guide rod is slidably connected in the through hole. The end of the guide rod is fixedly connected to the side wall of the main rod.

[0016] As a further description of the above technical solution:

[0017] A rubber sleeve is fitted onto the top of the main rod.

[0018] As a further description of the above technical solution:

[0019] The bottom end of the main rod is hinged to a base plate, and the bottom surface of the base plate is provided with an anti-slip pad.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, by moving two sets of main rods, the sliding rod extends from the end of the sleeve rod. The main rod drives one end of the traction plate to move laterally, and the other end of the traction plate rotates along the hinge point with the sleeve rod. The sliding plate is affected by the traction plate and moves vertically. The traction plate positions the sleeve rod, keeping the position of the sleeve rod stable, thereby avoiding discomfort and safety hazards caused by restricted activity space.

[0022] 2. In this utility model, by rotating the wheel, when the moving plate approaches the side wall of the main rod, the locking block enters the through groove and is inserted into the groove, thereby fixing the sliding plate and preventing it from moving vertically. This fixes the distance between the two sets of main rods, thus ensuring the stability of the safety ladder structure. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a retractable safety ladder for construction, comprising a main pole 1, with a rubber sleeve 11 fitted to the top of the main pole 1, and a base plate 12 hinged to the bottom of the main pole 1. An anti-slip pad 13 is provided on the bottom surface of the base plate 12. Two sets of main poles 1 are symmetrically arranged, forming the main support of the safety ladder. The rubber sleeve 11 fitted to the top of the main pole 1 provides protection against wear caused by contact between the top of the main pole 1 and objects. The base plate 12 increases the contact area with the ground, and the anti-slip pad 13 ensures good stability of the ladder during use, preventing slippage.

[0031] Reference Figure 2 - Figure 3A telescopic assembly 2 is provided between the two main rods 1. The telescopic assembly 2 includes a sleeve rod 21. Two sets of symmetrically arranged sliding rods 22 are slidably connected inside the sleeve rod 21. The sliding rods 22 are fixedly connected to the side wall of the main rod 1. The sleeve rod 21 and the two sets of sliding rods 22 form a telescopic step, allowing the distance between the two main rods 1 to be adjusted. A limit post 23 is fixedly connected to the side wall of the sliding rod 22. A limit groove 24 is opened in the side wall of the sleeve rod 21. The limit post 23 is slidably connected inside the limit groove 24. The limit post 23 and the limit groove 24 are used to limit the maximum moving length of the sliding rod 22 to prevent the sliding rod 22 from separating from the sleeve rod 21. The side walls of the main rods 1 are all provided with sliding rods. The slide 26 is slidably connected inside the groove 25. A traction plate 27 is hinged to the surface of the slide 26, and the end of the traction plate 27 is hinged to the side wall of the sleeve rod 21. The groove 25 provides space for the slide 26 to move vertically. When the two sets of main rods 1 open or close, the main rods 1 drive one end of the traction plate 27 to move laterally, causing the other end of the traction plate 27 to rotate along the hinge point with the sleeve rod 21. The slide 26 moves vertically under the influence of the traction plate 27, and the traction plate 27 positions the sleeve rod 21, keeping its position stable. A slot 28 is provided on the side wall of the slide 26. The slot 28 is used in conjunction with the positioning component 3 to fix the slide 26, keeping the distance between the two sets of main rods 1 fixed and ensuring the structural stability of the safety ladder.

[0032] Reference Figure 2 , Figure 4A positioning assembly 3 is provided on the side wall of the main rod 1. The positioning assembly 3 includes a threaded rod 31. One end of the threaded rod 31 is rotatably connected to the side wall of the main rod 1, and the other end of the threaded rod 31 is fixedly connected to a rotating wheel 32. A movable plate 33 is threadedly connected to the outer wall of the threaded rod 31. The rotating wheel 32 is used to drive the threaded rod 31 to rotate, so that the movable plate 33 threadedly connected to it moves closer to or away from the side wall of the main rod 1. A locking block 34 is fixedly connected to the side wall of the movable plate 33, and a passage for the locking block 34 to pass through is provided on the side wall of the main rod 1. The slot 35 and the locking block 34 are inserted into the inner wall of the slot 28. The slot 35 connects to the slide groove 25. When the moving plate 33 approaches the side wall of the main rod 1, the locking block 34 enters the slot 35 and engages with the slot 28, thereby fixing the slide plate 26 and preventing it from moving vertically, thus ensuring the stability of the safety ladder structure. When the moving plate 33 moves away from the side wall of the main rod 1, the locking block 34 separates from the slot 28, thereby releasing the fixing effect on the slide plate 26 and ensuring the stability of the safety ladder structure. The side wall of the moving plate 33 has a through hole, and a guide rod 36 is slidably connected in the through hole. The end of the guide rod 36 is fixedly connected to the side wall of the main rod 1. The guide rod 36 is used to guide the moving plate 33, so that the moving plate 33 moves axially along the outer wall of the guide rod 36, preventing the moving plate 33 from rotating with the rotation of the threaded rod 31.

[0033] Working principle: During use, rotating the wheel 32 drives the threaded rod 31 to rotate, causing the moving plate 33 to move away from the side wall of the main rod 1. The locking block 34 separates from the locking groove 28, thereby releasing the fixing effect on the slide plate 26. At the same time, the two sets of main rods 1 move, causing the slide rod 22 to extend from the end of the sleeve rod 21. The main rod 1 drives one end of the traction plate 27 to move laterally, and the other end of the traction plate 27 rotates along the hinge with the sleeve rod 21. The slide plate 26 is affected by the traction plate 27 and moves vertically. The traction plate 27 positions the sleeve rod 21, keeping the position of the sleeve rod 21 stable.

[0034] When the distance between the two sets of main rods 1 is adjusted, the rotating wheel 32 is rotated again so that when the moving plate 33 is close to the side wall of the main rod 1, the locking block 34 enters the through groove 35 and is inserted into the locking groove 28, thereby fixing the sliding plate 26 so that the sliding plate 26 cannot move in the vertical direction, thus fixing the distance between the two sets of main rods 1, thereby ensuring the stability of the safety ladder structure.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
