Description

Technical Field

[0001] This utility model relates to the field of shielding door technology, and more particularly to electric shielding doors. Background Technology

[0002] Shielding doors, also known as electromagnetic shielding doors, are devices that use metallic materials to reflect, absorb, or guide external electromagnetic waves. They are primarily used to protect internal electronic equipment from external electromagnetic interference. They mainly consist of a metallic shielding structure, a conductive sealing door, and a control system. The metallic shielding structure is typically made of metallic materials with good conductivity and reflectivity, such as aluminum alloys and copper alloys. These materials can effectively reflect, absorb, or guide external electromagnetic waves, thus achieving a shielding effect.

[0003] Most existing platform screen doors are opened and closed manually, which requires human intervention. Some platform screen doors are quite large, making it difficult for people with less strength to open them alone, thus making the opening and closing of platform screen doors quite troublesome. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The drive mechanism includes a motor, which is mounted on the door panel. A guide rail is provided on one side of the motor and on the door panel. A push rod is slidably fitted on the guide rail. A rotating connecting rod is rotatably connected to the push rod. The other end of the rotating connecting rod away from the push rod is rotatably connected to a rotating connecting plate.

[0008] The guide rail has a groove, and the push rod has a slider that slides on the groove on one side and a rack on the other side. The top of the push rod has a connector that is rotatably connected to the rotating connecting rod.

[0009] Furthermore, in a preferred configuration, a gear is mounted on the output end of the motor, and the gear meshes with the rack portion.

[0010] In addition, a preferred structure is that limit seats are symmetrically arranged on one side surface of the door frame, and limit blocks are provided on the limit seats.

[0011] In addition, a preferred structure is that the other end of the first connecting rod away from the rotating connecting plate is rotatably connected to a connecting mechanism, and the connecting mechanism is provided with a sliding bracket, which is mounted on the mounting frame.

[0012] Furthermore, in a preferred configuration, the connecting mechanism includes a connecting rod, one end of which is fixedly connected to a second rotating connector that is rotatably connected to the first connecting rod, and the other end of which is fixedly connected to a first rotating connector. A second connecting rod is rotatably connected to the first rotating connector, and the other end of the second connecting rod, away from the first rotating connector, is rotatably connected to a limiting mechanism, which is rotatably mounted on the mounting frame.

[0013] Furthermore, in a preferred configuration, a sliding block is provided on the sliding bracket, and the connecting rod is vertically slidably engaged with the sliding block.

[0014] Furthermore, in a preferred configuration, the limiting mechanism includes a rotating seat, which is mounted on the mounting frame, and the limiting mechanism is located on one side of the limiting seat. A crank connecting rod is rotatably mounted on the rotating seat, with one end of the crank connecting rod rotatably connected to the second connecting rod and the other end fixedly connected to a limiting block. A limiting groove is formed on the limiting block.

[0015] The beneficial effects of this utility model are as follows: This utility model connects the drive mechanism to the rotating connecting plate, so that after the motor works, it drives the push rod to push the rotating connecting rod, thereby realizing the electric rotation of the rotating connecting plate, thereby rotating the limit block and disengaging it from the limit block, so that the door can be opened quickly without the need for the operator to open the door manually.

A guide rail 32 has a sliding engagement with a push rod 33, and a rotating connecting rod 34 is rotatably connected to the push rod 33. The end of the rotating connecting rod 34 away from the push rod 33 is rotatably connected to the rotating connecting plate 7. The guide rail 32 has a groove 321. One side of the push rod 33 is provided with a slider 332 that is slidably engaged with the groove 321, and the other side is provided with a rack part 331. The top of the push rod 33 is provided with a connector 333 that is rotatably connected to the rotating connecting rod 34. The electric drive is achieved by the rotation of the motor 31.

[0030] Furthermore, a gear 311 is mounted on the output end of the motor 31, which meshes with the rack 331, allowing the motor 31 to drive the push rod 33 to move vertically.

[0031] Among them, a limit seat 4 is symmetrically arranged on the upper and lower sides of one side surface of the door frame 1, and a limit block 41 is provided on the limit seat 4. The limit block 41 is used to be stuck by the limit mechanism 9.

[0032] In addition, the other end of the first connecting rod 5 away from the rotating connecting plate 7 is rotatably connected to the connecting mechanism 6. The connecting mechanism 6 is provided with a sliding bracket 10, which is installed on the mounting frame 22. The sliding bracket 10 is used to ensure that the connecting mechanism 6 is vertically movable.

[0033] Meanwhile, the connecting mechanism 6 includes a connecting rod 63. One end of the connecting rod 63 is fixedly connected to a second rotating connector 62 that is rotatably connected to the first connecting rod 5, and the other end is fixedly connected to a first rotating connector 61. A second connecting rod 8 is rotatably connected to the first rotating connector 61. The other end of the second connecting rod 8, away from the first rotating connector 61, is rotatably connected to a limiting mechanism 9. The limiting mechanism 9 is rotatably mounted on the mounting frame 22. The second connecting rod 8 is used to perform the connecting function.

[0034] The sliding bracket 10 is provided with a sliding block 101, and the connecting rod 63 is vertically slidably engaged with the sliding block 101.

A limiting groove 921 is provided on the limiting block 92 to facilitate the entry of the limiting block 41.

[0036] In this embodiment, when it is necessary to open the shielding door and make the door leaf 2 rotate, the motor 31 can be controlled to work, the gear 311 rotates clockwise, and the push rod 33 on one side slides vertically upward on the guide rail 32, thereby driving the rotating connecting rod 34 to drive the rotating connecting plate 7 to rotate clockwise.

[0037] After the connecting plate 7 is rotated clockwise, it drives the first connecting rods 5 on both sides to rotate synchronously, so that the first connecting rod 5 pulls the connecting mechanism 6 up and down to move vertically on the sliding seat 10. Simultaneously, it drives the second connecting rod 8 to rotate the crank connecting rod 93. When the crank connecting rod 93 rotates, the limiting block 92 on one side rotates, and the limiting block 41 is disengaged from the limiting groove 921. At this time, the operator can open the door 2.

[0038] In this utility model, the drive mechanism 3 is connected to the rotating connecting plate 7, so that after the motor 31 works, it drives the push rod 33 to push the rotating connecting rod 34, thereby realizing the electric rotation of the rotating connecting plate 7, thereby rotating the limit block 92 and disengaging it from the limit block 41, so that the door 2 can be opened quickly without the need for the operator to open the door manually.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
