[0002] The main benefits of villa elevators lie in improving living comfort, increasing property value, enhancing quality of life, and strengthening residential safety. Villa elevators facilitate easy access to and from the house, especially for the elderly or those with mobility issues, eliminating the need to climb stairs and significantly improving convenience. Furthermore, using an elevator is safer and more convenient than using stairs when moving large items.

[0003] Currently, many villa elevators have suspended pits. To ensure the safety of equipment and personnel, it is necessary to add counterweight safety clamps. Most existing technologies require a large shaft space, which cannot meet the needs of the site. Utility Model Content

[0004] The purpose of this utility model is to provide a compact counterweight safety clamp linkage mechanism for villa elevators, which solves the problem that many villa elevators have suspended pits, requiring the addition of counterweight safety clamps to ensure the safety of equipment and personnel. Existing technologies mostly require a large shaft space, which cannot meet the needs of the site.

[0005] To achieve the above objectives, this utility model provides a compact counterweight safety clamp linkage mechanism for a villa elevator, comprising a counterweight lower beam, two safety clamps, two first connecting plates, two second connecting plates, two rotating plates, a linkage rod, two rotating columns, two torsion springs, and two connecting blocks. The two rotating columns are rotatably connected to the counterweight lower beam and located at both ends of the counterweight lower beam. The two torsion springs cover the surfaces of the corresponding rotating columns. The two rotating plates are bolted to the rotating columns and located on one side of the counterweight lower beam. The two rotating plates are centrally symmetrically arranged. The two ends of the linkage rod rotate with the corresponding rotating plates and are located between the corresponding two rotating plates. The two safety clamps are respectively disposed at both ends of the counterweight lower beam. The two first connecting plates are respectively fixedly connected to the corresponding rotating plates and located above the corresponding safety clamps. One end of each of the two second connecting plates is fixedly connected to the corresponding safety clamp, and the other end of each of the two second connecting plates is fixedly connected to the first connecting plate.

[0006] One side of the rotating plate is provided with a protruding plate.

[0007] The linkage rod has connecting blocks at both ends. One end of the connecting block is rotatably connected to the linkage rod, and the other end of the connecting block is rotatably connected to the protruding plate.

[0008] The torsion spring has locking blocks at both ends, and the two locking blocks are respectively engaged with the rotating column and the counterweight lower beam.

[0009] The compact villa elevator counterweight safety clamp linkage mechanism also includes two clamping plates, which are fixedly connected to the corresponding safety clamps and are located on opposite sides of the corresponding safety clamps.

[0010] This utility model discloses a compact counterweight safety clamp linkage mechanism for a villa elevator. Two rotating columns are rotatably connected to the lower counterweight beam and located at both ends of the lower counterweight beam. Two torsion springs cover the surfaces of the corresponding rotating columns. Two rotating plates are bolted to the rotating columns and located on one side of the lower counterweight beam. The two rotating plates are centrally symmetrically arranged. The two ends of a linkage rod rotate with the corresponding rotating plates and are located between the two corresponding rotating plates. Two safety clamps are respectively located at both ends of the lower counterweight beam. Two first connecting plates are respectively fixedly connected to the corresponding rotating plates and located above the corresponding safety clamps. Two second connecting plates... One end of the plate is fixedly connected to the corresponding safety clamp, and the other ends of the two second connecting plates are fixedly connected to the first connecting plate. When the elevator is running normally, the torsion spring controls the position of the safety clamp through its elastic force, presses the safety clamp downward, and drives the elevator's speed governor to operate normally, preventing the safety clamp from malfunctioning. When the elevator stalls, the speed governor detects that the elevator is traveling too fast, and the speed governor locks the speed governor wheel. The steel wire pulls the first connecting plate through friction, causing the corresponding rotating plate to rotate accordingly. Under the drive of the linkage rod, the rotating plate on the other side rotates accordingly, causing the two safety clamps to rise synchronously, so that the counterweight frame stops on the guide rail, improving safety and stability.

[0015] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0016] Please see Figures 1-2 ,in, Figure 1 This is a schematic diagram of the overall structure of the compact villa elevator counterweight safety clamp linkage mechanism of this utility model. Figure 2 This is a partial structural schematic diagram of the counterweight safety clamp linkage mechanism of the compact villa elevator of this utility model.

[0017] This utility model provides a compact counterweight safety clamp linkage mechanism for villa elevators, including a counterweight lower beam 1, two safety clamps 2, two first connecting plates 3, two second connecting plates 4, two rotating plates 5, a linkage rod 6, two rotating columns 7, two torsion springs 8, two locking plates 11, and two connecting blocks 9. The aforementioned solution solves the problem that many villa elevators currently have suspended pits, requiring the addition of counterweight safety clamps to ensure the safety of equipment and personnel. However, most existing technologies require a large shaft space, which cannot meet the needs of the site.

[0018] In this specific embodiment, the two rotating columns 7 are rotatably connected to the lower counterweight beam 1 and located at both ends of the lower counterweight beam 1. Two torsion springs 8 cover the surfaces of the corresponding rotating columns 7. Two rotating plates 5 are bolted to the rotating columns 7 and located on one side of the lower counterweight beam 1. The two rotating plates 5 are centrally symmetrically arranged. The two ends of the linkage rod 6 rotate with the corresponding rotating plates 5 and are located between the corresponding two rotating plates 5. Two safety clamps 2 are respectively disposed at both ends of the lower counterweight beam 1. Two first connecting plates 3 are respectively fixedly connected to the corresponding rotating plates 5 and located above the corresponding safety clamps 2. Two second connecting plates 3... One end of plate 4 is fixedly connected to the corresponding safety clamp 2, and the other ends of the two second connecting plates 4 are fixedly connected to the first connecting plate 3. When the elevator is running normally, the torsion spring 8 controls the position of the safety clamp 2 through elastic force, presses the safety clamp 2 downward, and drives the elevator speed governor to operate normally to prevent the safety clamp 2 from acting erroneously. When the elevator stalls, the speed governor detects that the elevator is traveling too fast, the speed governor locks the speed governor wheel, and the steel wire pulls the first connecting plate 3 through friction, so that the corresponding rotating plate 5 rotates accordingly. Under the drive of the linkage rod 6, the rotating plate 5 on the other side rotates accordingly, so that the two safety clamps 2 rise synchronously, so that the counterweight frame stops on the guide rail.

[0019] One side of the rotating plate 5 is provided with a protruding plate 10. The protruding plate 10 is disposed on the rotating plate 5. When the rotating plate 5 rotates, the protruding plate 10 rotates accordingly, pulling the linkage rod 6, so that the protruding plate 10 on the other side drives the rotating plate 5 to rotate accordingly.

[0020] Secondly, connecting blocks 9 are provided at both ends of the linkage rod 6. One end of the connecting block 9 is rotatably connected to the linkage rod 6, and the other end of the connecting block 9 is rotatably connected to the protruding plate 10. The connecting block 9 is locked on the protruding plate 10. When the protruding plate 10 moves, the connecting block 9 rotates around the protruding plate 10 to push the linkage rod 6, so that the linkage rod 6 moves accordingly.

[0021] Then, the two ends of the torsion spring 8 are provided with locking blocks 12. The two locking blocks 12 are respectively engaged with the rotating column 7 and the counterweight lower beam 1. One end of the torsion spring 8 is fixed to the counterweight lower beam 1, so that the torsion spring 8 rotates the rotating column 7 under the elastic action, so that the rotating plate 5 presses down on the safety clamp 2 accordingly.

[0022] In addition, the compact villa elevator counterweight safety clamp linkage mechanism also includes two clamping plates 11. The two clamping plates 11 are fixedly connected to the corresponding safety clamps 2 respectively and are located on one side of the corresponding safety clamps 2. The two clamping plates 11 limit the safety clamps 2 and effectively prevent the safety clamps 2 from being misaligned.

[0023] When using this utility model, during normal elevator operation, one end of the torsion spring 8 is fixed to the counterweight lower beam 1, causing the torsion spring 8 to rotate the rotating column 7 under elastic action. This causes the rotating plate 5 to press down on the safety clamp 2 accordingly, and drives the elevator speed governor to operate normally, preventing the safety clamp 2 from malfunctioning. When the elevator stalls, the speed governor detects that the elevator is traveling too fast. The speed governor locks the speed governor wheel, and the steel wire pulls the first connecting plate 3 through friction, causing the corresponding rotating plate 5 to rotate accordingly. The protruding plate 10 rotates, and the connecting block 9 rotates around the protruding plate 10 to push the linkage rod 6. The rotating plate 5 on the other side rotates accordingly, causing the two safety clamps 2 to rise synchronously, thus stopping the counterweight frame on the guide rail.

[0024] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
