Description

Technical Field

[0001] This utility model relates to the field of elevator safety protection technology, and in particular to a mechanical safety frame design scheme for a platform villa elevator. Background Technology

[0002] With the improvement of family living standards, villa elevators have been widely used in high-end residences. Platform villa elevators are popular due to their compact structure and the elimination of the need for shafts and dedicated machine rooms. However, these elevators often lack enclosed car doors or use a half-door design, leading to safety hazards at the platform edges during operation, especially during ascent or descent, which can easily result in accidents such as people being trapped or foreign objects intruding into the operating space. Current technologies often use electronic sensors such as infrared light curtains for safety detection, but these devices suffer from high costs, complex installation, and high malfunction rates, making them unsuitable for long-term reliable use in residential environments. Meanwhile, some mechanical safety frame devices have defects such as structural instability, insensitive rebound, and rough appearance. Therefore, developing a simple, low-cost, safe, reliable, responsive, and aesthetically pleasing mechanical safety frame device has become an important requirement for platform villa elevator safety technology. Summary of the Invention

[0003] To address the aforementioned technical problems, this utility model relates to a mechanical safety frame for a platform villa elevator, solving issues such as insensitive operation, easy loosening, complex structure, and high cost of existing frame devices, thereby improving user safety and user experience. To achieve the above objectives, this utility model is implemented through the following technical solution:

It includes a car bottom welded component (1), a safety frame side frame (2), a safety frame front frame (3), a flat-head bolt (4), a guide pin (5), a connecting bracket (6), a frame fixing component (7), a micro switch (8), a connecting bolt (9), and a pressure spring (10). Its features include: the flat-head bolt (4) is an internal hexagonal flat-head structure, using a semi-concealed installation; the safety frame side frame (2) and the safety frame front frame (3) are made of spray-painted steel plate; the micro switch (8) is located inside the frame fixing component (7); the connection between the safety frame side frame (2) and the frame fixing component (7) has two C-shaped bends of different heights, which are engaged by the guide pin (5) to form a cavity structure; the frame fixing component (7) is slidably connected to the safety frame side frame (2) through the guide pin (5); and a pressure spring providing rebound force is installed inside the cavity. (10) and a micro switch (8) that triggers the elevator stop signal; the frame fixing part (7) is connected to the car bottom welding part (1) by connecting bolts (9); the safety frame front frame (3) is connected to the safety frame side frames (2) on both sides by connecting brackets (6) to form an integrated structure; the micro switch (8) is connected to the elevator safety circuit by a preset wiring. When the safety frame side frame (2) or the front frame (3) is compressed by external force, the micro switch (8) is triggered to control the elevator to stop running; after the external force is removed, the pressure spring (10) rebounds, the micro switch (8) resets, and the elevator resumes operation.

[0005] This utility model is applicable to villa elevators. Compared with the prior art, the beneficial effects of this utility model are:

[0006] 1. The mechanical structure operates reliably and responds sensitively;

[0007] 2. It does not rely on electrical signal detection, resulting in a low false alarm rate;

[0016] The present invention will now be described in detail with reference to the accompanying drawings:

[0017] like Figure 1 As shown, the overall structure is based on the car bottom welded part (1) as the basic installation component. It is initially positioned by the flat head bolt (4) and the safety side frame (2) and the safety front frame (3). The guide pin (5) is inserted between the frame fixing part (7) and the side frame (2) as a key sliding connection to ensure the compressibility of the frame in the direction of force.

[0018] like Figure 2 As shown, the safety frame is firmly connected to the car bottom welded part (1) through the connecting bracket (6), and the frame fixing part (7) cooperates with the guide pin (5) so that the safety frame side frame (2) can be compressed and moved on the guide path under the action of external force. The micro switch (8) is fixed on the frame fixing part (7) and close to its moving area, and is connected to the platform structure through the connecting bolt (9); at the same time, a pressure spring (10) is provided between the frame fixing part and the safety frame side frame to realize the automatic rebound function after being subjected to force.

[0019] like Figure 3 As shown, when a person's limb or a foreign object intrudes into the elevator's operating space and squeezes the safety frame, the side frame (2) or front frame (3) of the safety frame is pressed down along the direction of the guide pin (5) under the action of external force, causing the frame fixing part (7) to move, so that the micro switch (8) is pressed and triggered, sending a signal to the elevator control system to control the elevator to stop running. At this time, the pressure spring (10) is compressed and stored.

[0020] like Figure 4 As shown, when the external force is removed, the pressure spring (10) releases its elastic force to push the frame fixing part (7) and the safety frame side frame (2) back, and the micro switch (8) is reset accordingly. The elevator control system releases the stop signal and resumes normal operation. This action process is purely mechanical linkage, with rapid response, simple structure, and good stability and maintainability.
