Description

Technical Field

[0001] This application relates to the field of home elevator technology, specifically a fast-response anti-pinch component for home elevators. Background Technology

[0002] A home elevator is an elevator installed in a private residence for the exclusive use of a single family member. It can also be installed in buildings not used by a single family, but primarily serves as a means for that family to access their home; access and use by the general public or other residents are typically inaccessible. When choosing a home elevator, primary factors to consider include whether there are elderly people living in the household, availability of installation space, and sufficient budget.

[0003] By opening the doors of the home elevator and allowing people to enter, and then closing the doors, the elevator's internal lifting mechanism can move people up or down. The doors do not move with the elevator's passenger-carrying mechanism; they only serve to block the passageway between floors, providing safety for people before reaching their designated floor.

[0004] When the doors of a home elevator rotate and close, a woman's long skirt, because it flows gracefully while walking, can cause one end of the skirt to get caught when the door closes. This can then cause damage to the garment as the elevator moves up or down. Utility Model Content

[0005] The purpose of this application is to provide a fast-response anti-pinch component for home elevators, in order to solve the problem mentioned in the background art where, during the closing process of a door, one end of a skirt is pinched and the garment is damaged.

[0006] To achieve the above objectives, this application provides the following technical solution: a fast-response anti-pinch component for home elevators, comprising: a frame, a protective door, and a limiting and blocking mechanism. The protective door is rotatably connected inside the frame, and the limiting and blocking mechanism is disposed on the inner wall of the frame. The limiting and blocking mechanism includes a slide rail fixed on the inner wall of the frame and a pressing block slidably connected inside the slide rail. The limiting and blocking mechanism also includes a fixing block welded to one side of the slide rail and a spring attached to the outer wall of the fixing block. The fixing block has a through hole inside, a threaded hole in the center of the fixing block, and the other end of the spring is attached to the pressing block.

[0007] By adopting the above technical solution, horizontal compression can be used to displace the structure on one side, thereby achieving the effect of resisting.

[0008] Preferably, the limiting and blocking mechanism further includes a slider that is horizontally slidably connected inside the slide rail, and the slider is welded to the outer wall of the pressing block.

[0009] By adopting the above technical solution, a stable connection structure can be provided for movement.

[0010] Preferably, the limiting and blocking mechanism further includes a guide rod horizontally welded to the outer wall of the pressing block, and the guide rod is connected through the through hole of the fixing block.

[0011] By adopting the above technical solution, the springs sleeved on the outer wall can stably compress the structure in the horizontal direction during the displacement process of the structure connected on one side.

[0012] Preferably, the limiting and blocking mechanism further includes a stop block welded to one end of the guide rod, and the diameter of the stop block is slightly larger than the diameter of the through hole of the fixing block.

[0013] By adopting the above technical solution, it is possible to ensure that the structure connected on one side will not detach when moving horizontally.

[0014] Preferably, the limiting and blocking mechanism further includes a movable block that is horizontally slidably connected to the guide rod, and a circular hole is provided in the center of the movable block.

[0015] By adopting the above technical solution, the spring on one side can be adjusted in elasticity during the displacement process.

[0016] Preferably, the limiting and blocking mechanism further includes a threaded rod disposed in the threaded hole of the fixed block and an annular block welded to one end of the threaded rod, and the annular block is located on both sides of the movable block.

[0017] By adopting the above technical solution, it is possible to drive the structure on one side to move stably in the horizontal direction during the rotation process.

[0018] Preferably, the limiting and blocking mechanism further includes a rotating handle that is engaged and fixed on the other end of the threaded screw.

[0019] By adopting the above technical solution, a comfortable grip can be provided for the user, thus ensuring stable subsequent rotation.

[0020] In summary, this application has the following beneficial effects: by setting a limit blocking mechanism, the pressure block is squeezed by the spring and thus located on the outside of the frame. When the protective door is closed, the protective door is affected by the pressure block, and a gap is created between the protective door and the frame. At this time, the person needs to exert force again to close it completely. During the process of exerting force again, the person can have time to observe whether the clothes are in the gap between the protective door and the frame. Attached Figure Description

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] The following is in conjunction with the appendix Figure 1-4 The embodiments of this application will be described in further detail.

[0028] Example 1

[0029] Please see Figures 1-4 This embodiment provides a technical solution: a fast-response anti-pinch component for home elevators, comprising: a frame 1, a protective door 2, and a limiting and blocking mechanism 3.

[0030] Frame 1 provides a stable and fixed connection between structures. The protective door 2 is rotatably connected inside the frame 1. After the protective door 2 is closed, it can ensure the safety of personnel inside the frame 1 during subsequent lifting and lowering. One side of the protective door 2 is integrally formed with a buffer pad to prevent collisions that could cause dents in the protective door 2 when it comes into contact with the structure on one side. The limiting and blocking mechanism 3 is set on the inner wall of the frame 1. The limiting and blocking mechanism 3 can provide sufficient time for personnel to check whether their clothing is in the gap between the frame 1 and the protective door 2 during the closing process.

[0031] The limiting and blocking mechanism 3 includes a slide rail 301 bolted to the inner wall of the frame 1. The slide rail 301 provides stable horizontal displacement for the internal structure. A slider 302 is horizontally connected inside the slide rail 301. During displacement, the slider 302 drives the structure connected on one side to slide stably horizontally inside the slide rail 301. A pressing block 303 is slidably connected inside the slide rail 301. During displacement, the pressing block 303 can prevent the protective door 2 from closing directly. The slider 302 is welded to the outer wall of the pressing block 303, providing stability for the pressing block 303 during horizontal movement. A guide rod 304 is horizontally welded to the outer wall of the pressing block 303, which stably connects the structure on the outer wall.

[0032] A stop 305 is welded to one end of the guide rod 304. The stop 305 can provide a stable connection between the structures. The limiting and blocking mechanism 3 also includes a fixing block 306 welded to one side of the slide rail 301. The diameter of the stop 305 is slightly larger than the diameter of the through hole of the fixing block 306, which can prevent the guide rod 304 from deviating during its movement inside the through hole of the fixing block 306. The fixing block 306 has a through hole inside, and the guide rod 304 passes through and is connected inside the through hole of the fixing block 306, which can provide the guide rod 304 to move stably in the horizontal direction inside the fixing block 306. A threaded hole is opened in the center of the fixing block 306, which can provide the internal structure to move synchronously during rotation. A spring 307 is attached to the outer wall of the fixing block 306, and the other end of the spring 307 is attached to the pressing block 303. The spring 307 can drive the pressing block 303 on one side to move horizontally by horizontal compression.

[0033] Once inside frame 1, personnel can close the protective door 2 by rotating it. At this time, the protective door 2 will be held in place by the pressure block 303, creating a gap between it and frame 1. This provides sufficient time for personnel to observe whether their clothing is inside the gap. When personnel forcefully close the protective door 2 again, the protective door 2 will cause the pressure block 303 to move stably inside the slide rail 301 via the slider 302. Meanwhile, the guide rod 304 connected to the outer wall of the pressure block 303 moves stably inside the fixed block 306, thereby causing the spring 307 sleeved on the guide rod 304 to contract, allowing the protective door 2 to close stably on frame 1.

[0034] Example 2

[0035] Please see Figures 1-4This embodiment provides a technical solution: a fast-response anti-pinch component for home elevators, including: a movable block 308, a threaded screw 309, an annular block 310, and a rotating handle 311;

[0036] A movable block 308 is horizontally slidably connected to the guide rod 304. The movable block 308 can stably move on the guide rod 304. During the movement, the movable block 308 can drive the spring 307 attached to one side to adjust the tension. A round hole is provided in the center of the movable block 308 to provide a through-hole for the internal structure. A threaded rod 309 is provided in the threaded hole of the fixed block 306. The threaded rod 309 can rotate stably in the threaded hole of the fixed block 306, thereby performing subsequent horizontal movement. The threaded rod 309 moves, and one end of the threaded rod 309 is located inside the circular hole of the movable block 308. An annular block 310 is welded to one end of the threaded rod 309, and the annular block 310 is located on both sides of the movable block 308. The annular block 310 can provide the threaded rod 309 to drive the movable block 308 to move horizontally in sync during the rotation displacement process. A rotating handle 311 is locked and fixed on the other end of the threaded rod 309. The rotating handle 311 can be easily held by the operator, thereby driving the threaded rod 309 connected on one side to rotate stably.

[0037] The pressure block 303 is compressed by the spring 307, thus blocking the closing of the protective door 2. Since the pulling force of each person's hand is different, the threaded screw 309 can be rotated by holding the rotating handle 311. During the rotation of the threaded screw 309, the movable block 308 inside the annular block 310 moves stably on the guide rod 304. When the movable block 308 is displaced, it will adjust the tension of the spring 307, thereby adjusting the force on the pressure block 303 when the protective door 2 is rotated.

[0038] The implementation principle of the fast-response anti-pinch component for home elevators in this application is as follows:

[0039] First, when a person enters the frame 1, the protective door 2 of the frame 1 is closed by rotating it. At this time, the protective door 2 will be blocked by the pressure block 303, thus creating a gap between it and the frame 1, providing the person with enough time to observe whether their clothes are in the gap.

[0040] Secondly, when the personnel forcefully close the protective door 2 again, the protective door 2 will drive the pressure block 303 to move stably inside the slide rail 301 through the connection of the slider 302. At this time, the guide rod 304 connected to the outer wall of the pressure block 303 moves stably inside the fixed block 306, thereby driving the spring 307 sleeved on the guide rod 304 to contract, so that the protective door 2 can be stably closed on the frame 1.

[0041] Finally, the pressure block 303 is compressed by the spring 307, thus blocking the closing of the protective door 2. Since the pulling force of each person's hand is different, the threaded screw 309 can be rotated by holding the rotating handle 311. During the rotation of the threaded screw 309, the movable block 308 inside the annular block 310 moves stably on the guide rod 304. At this time, when the movable block 308 is displaced, it will adjust the tension of the spring 307, thereby adjusting the force on the pressure block 303 when the protective door 2 is rotated.

[0042] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
