Description

A type of movable lifting actor trapdoor Technical Field

[0001] This utility model relates to the field of performing arts equipment engineering, and in particular to a mobile lifting actor's hatch. Background Technology

[0002] Currently, in the performing arts equipment field, the common size of the actor's door structure on a lifting platform is 1m×1m, and it adopts a flip-up structure. If the actor's door is to be completely hidden inside the platform, it necessarily means that the platform height must be no less than 1m; however, if the issue of hiding the actor's door is not considered, it will bring certain safety hazards or greatly reduce the aesthetics of the lifting platform. Summary of the Invention

[0003] The purpose of this utility model is to address the problems existing in the prior art mentioned above by providing a mobile lifting actor's door. By designing the flipping motion as a lifting motion, the height space required for the actor's door during use is greatly reduced, so that the maximum external dimension of the actor's door can be reduced to 550mm, which provides more freedom for the design of the height of the lifting platform.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A movable lifting-type actor's door includes a door panel, a guide rail, a four-bar linkage mechanism, and a lifting platform. The guide rail and the four-bar linkage mechanism are both located below the lifting platform. The door panel is fixed to the top of the four-bar linkage mechanism. The lifting platform has pre-drilled holes that match the door panel. The guide rail consists of a horizontal section and a vertical section. An electric push rod is fixed on the guide rail. The movable end of the electric push rod is connected to the four-bar linkage mechanism. The electric push rod drives the four-bar linkage mechanism to move along the guide rail, causing the door panel to move horizontally or vertically.

[0006] Furthermore, the four-bar linkage includes an upper frame, a lower frame, connecting rods, and a wheel assembly. The four connecting rods are symmetrically arranged, and the two ends of each connecting rod are rotatably connected to the upper frame and the lower frame through the wheel assembly, respectively. The movable end of the electric push rod is connected to the lower frame, and the wheel assembly rolls in contact with the guide rail.

[0007] Furthermore, the guide rail is made of two parallel channel steels, the fixed end of the electric push rod is fixed to the connecting channel steel, and the connecting channel steel is fixedly connected between the guide rails.

[0008] Furthermore, the wheel assembly includes a wheel and a mounting shaft. The wheel is rotatably mounted on the mounting shaft. The upper frame, lower frame, and connecting rods are all rotatably connected to the mounting shaft through ear plates. The wheel at the lower end of each connecting rod always moves within the groove of the horizontal section of the guide rail. When the door panel moves horizontally on the guide rail, the wheel at the upper end of each connecting rod moves on the upper surface of the guide rail.

[0009] Preferably, a limiting sleeve is provided between the ear plate and the mounting shaft.

[0010] Furthermore, a limit rod is provided between the lower frame and the left connecting rod. The upper end of the limit rod is rotatably connected to the connecting rod, and the lower end of the limit rod is slidably connected to a slot on the horizontal beam of the lower frame through a pin assembly.

[0011] Due to the adoption of the above technical solution, the beneficial technical effects of this utility model are as follows:

[0012] This utility model discloses a mobile lifting-type actor's door. The four-bar linkage mechanism driven by the electric push rod moves along the guide rail, allowing the door to move horizontally or vertically. The traditional flip-type actor's door is designed as a lifting-type actor's door, which greatly reduces the height space required for the actor's door during use. The maximum external dimension of the actor's door can be reduced to 550mm, which provides more freedom in the design of the height of the lifting platform. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following describes this utility model in further detail through preferred embodiments.

[0019] Example

[0020] Please refer to Figures 1-4. This embodiment provides a movable lifting actor's door, including a door wooden decoration 1, a guide rail 2, a four-bar linkage mechanism, and a lifting platform 14. The guide rail 2 and the four-bar linkage mechanism are both located below the lifting platform 14. The door wooden decoration 1 is fixed to the top of the four-bar linkage mechanism. The lifting platform 14 has holes that match the door wooden decoration 1. The guide rail 2 consists of a horizontal section and a vertical section. An electric push rod 8 is fixed on the guide rail 2. The movable end of the electric push rod 8 is connected to the four-bar linkage mechanism. The electric push rod 8 drives the four-bar linkage mechanism to move along the guide rail 2, so that the door wooden decoration 1 can move horizontally or vertically.

[0021] Specifically, the four-bar linkage includes an upper frame 3, a lower frame 4, connecting rods 6, and a wheel assembly 7. The four connecting rods 6 are symmetrically arranged, and the two ends of each connecting rod 6 are rotatably connected to the upper frame 3 and the lower frame 4 through the wheel assembly 7, respectively. The movable end of the electric push rod 8 is connected to the lower frame 4, and the wheel assembly 7 rolls in contact with the guide rail 2. The guide rail 2 is made of two parallel channel steels, and the fixed end of the electric push rod 8 is fixed to the connecting channel steel, which is fixedly connected between the guide rails 2.

[0022] Specifically, the wheel assembly 7 includes a wheel 9 and a mounting shaft. The wheel 9 is rotatably mounted on the mounting shaft. The upper frame 3, the lower frame 4, and the connecting rod 6 are all rotatably connected to the mounting shaft through the ear plate 10. The wheel 9 at the lower end of each connecting rod 6 always moves within the groove of the horizontal section of the guide rail 2. When the door wood decoration 1 moves horizontally on the guide rail 2, the wheel 9 at the upper end of each connecting rod 6 moves on the upper surface of the guide rail 2 to avoid travel interference.

[0023] Preferably, a limiting sleeve 11 is provided between the ear plate 10 and the mounting shaft to avoid interference and ensure safe operation.

[0024] Specifically, a limit rod 5 is provided between the lower frame 4 and the left connecting rod 6. The upper end of the limit rod 5 is rotatably connected to the connecting rod 6, and the lower end of the limit rod 5 is slidably connected to a slot on the horizontal beam 13 of the lower frame through a pin assembly 12. The limit rod 5 ensures that the rotation angle of the connecting rod 6 is less than 90°, avoiding potential dead positions or rollover problems. The pin assembly 12 can be a pin, a cotter pin, or a washer.

[0025] In this invention, an electric push rod 8 drives a four-bar linkage mechanism, causing the four-bar linkage mechanism to move differently at different positions on the guide rail 2, thereby enabling the trapdoor wooden decoration 1 to move horizontally or vertically. Specifically, the electric push rod 8 acts on the lower frame 4. As the movable end of the electric push rod 8 extends and applies displacement, the lower frame 4 and its wheel assembly 7 move within the groove of the guide rail 2. When the wheel assembly 7 on the upper frame 3 contacts the vertical section of the guide rail 2 and obstructs the horizontal movement of the upper frame 3, the horizontal stroke of the electric push rod 8 is converted into the vertical movement of the upper frame 3. Accordingly, before the trapdoor wood trim 1 moves directly below the reserved hole on the lifting platform 14, the lower frame 4 always moves within the groove of the guide rail 2, and the upper frame 3 moves on the upper surface of the guide rail 2 by means of the wheel assembly 7. The trapdoor wood trim 1 moves horizontally. When the trapdoor wood trim 1 moves directly below the reserved hole, the vertical section of the guide rail 2 restricts the displacement of the upper frame 3. With the continued action of the electric push rod 8, the connecting rod 6 rotates counterclockwise, the upper frame 3 moves vertically, and the trapdoor wood trim 1 moves vertically upward until it is level with the lifting platform 14.

[0026] The above description is a preferred embodiment of the present utility model, used to explain the technical solution of the present utility model. Those skilled in the art can also make conventional modifications, equivalent substitutions and improvements within the spirit and principles of the present utility model.
