Description

Technical Field

[0001] This utility model relates to the field of elevator maintenance devices, and in particular to a detachable safety fence component for elevator maintenance. Background Technology

[0002] In elevator maintenance work, safety protection is a key aspect of ensuring the safety of maintenance personnel and those in the surrounding area. Safety fences, as important equipment for isolating maintenance areas and preventing unauthorized personnel from entering, directly affect the efficiency and safety of maintenance work in terms of their practicality and convenience.

[0003] Most traditional safety fences are one-piece structures, which are quite large in size. When not in use, they require a lot of storage space (such as maintenance tool rooms and transport vehicles), and the weight distribution is uneven, making it difficult for a single maintenance person to move them. They are also inconvenient to transport or store.

[0004] In response to the technical problem that most traditional safety fences are bulky and inconvenient to transport and store, this application proposes a detachable safety fence component for elevator maintenance. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of most traditional safety fences, which are bulky and inconvenient to transport and store. It proposes a detachable safety fence component for elevator maintenance, which allows the suction cups to be removed and replaced, avoiding damage to the suction cups that would prevent the baffle from being fixed to the wall at the elevator entrance. It also saves on equipment maintenance costs and allows the entire device to be folded up when not in use, making it easy for maintenance personnel to transport.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a detachable safety fence assembly for elevator maintenance, comprising left and right side panels, with a first connecting block and a second connecting block respectively fixedly connected to the rear ends of the left and right side panels, a rotating shaft fixedly connected to the inner wall of the second connecting block, the upper side of the outer wall of the rotating shaft rotatably connected to the inner wall of the first connecting block, a ratchet fixedly connected to the upper side of the outer wall of the rotating shaft, a limit assembly provided on the outer wall of the ratchet, threaded rods rotatably connected to the upper and lower sides of the inner wall of the panel, the threaded rods being connected to a connecting seat through a fixing assembly, and a suction cup fixedly connected to the rear end of the connecting seat.

[0007] Furthermore, the limiting component includes a rod slidably connected to the inner wall of the first connecting block, and a ratchet is fixedly connected to the rear end of the rod, the ratchet engaging with the ratchet wheel.

[0008] Furthermore, a spring is sleeved on the outer wall of the insertion rod, one end of the spring is connected to the ratchet, and the other end of the spring is connected to the inner wall of the first connecting block.

[0009] Furthermore, the fixing component includes a threaded sleeve threadedly connected to the outer wall of the threaded rod, the outer wall of the threaded sleeve being slidably connected to the inner wall of the baffle, and connecting rods being rotatably connected to both sides of the outer wall of the threaded sleeve.

[0010] Furthermore, each of the connecting rods has a slider rotatably connected to its other end. The outer wall of the slider is slidably connected to the inner wall of the baffle. Each slider has a fixed plate fixedly connected to its rear end. The fixed plates are located on both sides of the outer wall of the connecting seat.

[0011] Furthermore, each threaded rod has a knob fixedly connected to its front end for driving the threaded rod to rotate.

[0012] Furthermore, a handle is fixedly connected to the top of the left-side baffle, and two limiting blocks are fixedly connected to the right end of the left-side baffle.

[0013] This utility model has the following beneficial effects: 1. In this utility model, by rotating the knob to drive the threaded rod to rotate, the fixing plates on both sides will loosen the connecting seat, so that the suction cup can be removed for replacement. This avoids damage to the suction cup, which would prevent the baffle from being fixed to the wall at the elevator entrance, thus saving equipment maintenance costs and extending the service life of the overall device. 2. In this utility model, by rotating the left baffle to the front end of the right baffle, the entire device can be folded up when not in use. The folded structure is more compact and the weight distribution is more concentrated, making it easy for maintenance personnel to carry or conveniently place in the storage area of ​​the maintenance vehicle.

[0016] 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.

[0017] Reference Figures 1-3 This utility model provides an embodiment of a detachable safety fence assembly for elevator maintenance, comprising left and right side panels 1, with a first connecting block 2 and a second connecting block 3 fixedly connected to the rear ends of the left and right side panels 1 respectively. A rotating shaft 4 is fixedly connected to the inner wall of the second connecting block 3, and the upper side of the outer wall of the rotating shaft 4 is rotatably connected to the inner wall of the first connecting block 2. (Refer to...) Figure 4 A ratchet 5 is fixedly connected to the upper side of the outer wall of the rotating shaft 4. A rod 6 is slidably connected to the inner wall of the first connecting block 2. A ratchet 7 is fixedly connected to the rear end of the rod 6. The ratchet 7 engages with the ratchet 5. A spring 8 is sleeved on the outer wall of the rod 6. One end of the spring 8 is connected to the ratchet 7, and the other end of the spring 8 is connected to the inner wall of the first connecting block 2. A handle is fixedly connected to the top of the left baffle 1, and two limit blocks 17 are fixedly connected to the right end of the left baffle 1.

[0018] Specifically, when the left and right side baffles 1 are fully unfolded, the limiting block 17 at the right end of the left side baffle 1 will limit the right side baffle 1, so that it can only rotate to the horizontal position and cannot continue to rotate backward. When folding, the right side baffle 1 can be rotated directly to the rear end of the left side baffle 1. At this time, the ratchet 5 and the ratchet 7 are in inclined contact, so that the baffle 1 can directly drive the rotating shaft 4 to rotate. When the right side baffle 1 is rotated to the rear end of the left side baffle 1, the ratchet 5 and the ratchet 7 will engage with each other to prevent the baffle 1 from loosening. The handle above the left side baffle 1 makes it easy to move the whole device.

[0019] Reference Figure 1 , Figure 5 and Figure 6Both the upper and lower sides of the inner wall of the baffle 1 are rotatably connected to threaded rods 10. The outer wall of the threaded rod 10 is threadedly connected to a threaded sleeve 11. The outer wall of the threaded sleeve 11 is slidably connected to the inner wall of the baffle 1. Both sides of the outer wall of the threaded sleeve 11 are rotatably connected to connecting rods 12. The other end of the connecting rod 12 is rotatably connected to a slider 13. The outer wall of the slider 13 is slidably connected to the inner wall of the baffle 1. The rear end of the slider 13 is fixedly connected to a fixing plate 14. The fixing plates 14 are located on both sides of the outer wall of the connecting seat 15. The front end of the threaded rod 10 is fixedly connected to a knob 9 for driving the threaded rod 10 to rotate. The rear end of the connecting seat 15 is fixedly connected to a suction cup 16.

[0020] Specifically, slots are provided on both the upper and lower sides of the rear end of the baffle 1. The connecting seat 15 fits the shape of the slot, so that the connecting seat 15 can be completely fitted into the slot. The suction cup 16 is usually made of rubber or silicone, which has good elasticity and sealing performance. By expelling the internal air, a negative pressure is formed inside the suction cup 16. The external atmospheric pressure presses the suction cup 16 tightly against the wall surface, thereby generating friction and adsorption force, and fixing the baffle 1 connected to the suction cup 16 to the walls on both sides of the elevator door.

[0021] Working principle: When in use, pull the insertion rod 6, causing the insertion rod 6 to drive the ratchet 7 forward. The ratchet 7 compresses the spring 8, and at the same time, the ratchet 7 disengages from the outer wall of the ratchet 5, allowing the ratchet 5 to rotate. This allows the rotating shaft 4 to rotate on the inner wall of the first connecting block 2. Then, rotate the rear baffle 1 to the right, causing the baffles 1 on both sides to unfold. The spring 8 will rebound, and the ratchet 7 will engage with the ratchet 5. Then, press the baffles 1 on both sides of the elevator entrance onto the walls on both sides, causing the suction cup 16 to adhere to the walls at the elevator entrance, thus fixing the baffle 1 to the elevator entrance and serving as a safety warning. When the suction cup 16 is damaged and needs to be replaced, turn the knob 9, causing the knob 9 to drive the threaded rod 10 to rotate. The threaded rod 10 then drives the threaded sleeve 11 to move, and the threaded sleeve 11 drives the rear end of the connecting rod 12 to move to both sides. The connecting rod 12 then drives the slider 13 to slide to both sides, thereby moving the fixing plates 14 on both sides outward, so that they are no longer fixed to the connecting seat 15, allowing the suction cup 16 to be removed for replacement.

[0022] 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.
