Abstract
Description
Technical Field
[0001] The present application relates to a swing rod structure of an airtight protection door, and in particular to a torque swing rod mechanism for an electrically switched airtight protection door. Background Art
[0002] When the traditional protection door leaf is opened and closed, it is generally pushed by a hydraulic push rod, or a driving mechanism is directly arranged at the hinge to drive. For the protection equipment door with an airtight function, when the door is closed in place, the door leaf also needs to move forward and compress the sealing strip. The opening and closing mechanism of the traditional protection equipment door is likely to cause eccentric loading when the door leaf reaches the position, affecting the locking of the locking mechanism and the airtight effect. Summary of the Utility Model
[0003] In view of this, the present application provides a torque swing rod mechanism for an electrically switched airtight protection door, which can at least solve the above-mentioned technical problems.
[0004] According to one aspect of the present application, there is provided a torque swing rod mechanism for an electrically switched airtight protection door, including: a swing rod, a driving motor, a driving output component and a chute component. The first end of the swing rod is connected to the driving output component, and a sliding shaft is arranged at the second end of the swing rod. The sliding shaft is inserted into the chute component and can slide in the chute component. The chute component is fixedly connected to the airtight protection door, and the driving output component is arranged on the output rotating shaft of the driving motor. The output rotating shaft of the driving motor rotates in a first direction, drives the sliding shaft of the swing rod to slide in the chute component through the driving output component, and pushes the airtight protection door to open. The output rotating shaft of the driving motor rotates in a second direction, drives the sliding shaft of the swing rod to slide in the chute component through the driving output component, and pushes the airtight protection door to close.
[0005] In some exemplary embodiments, the driving output component is arranged on one side of the pivot structure of the airtight protection door;
[0006] The driving motor is arranged in the wall on one side of the pivot structure of the airtight protection door;
[0007] The chute component is arranged horizontally along the airtight protection door, and the first end of the chute component is close to one side of the pivot structure of the airtight protection door.
[0008] In some exemplary embodiments, the chute component includes a chute angle steel and a lower support plate;
[0009] The chute angle steel is in a ⊐ - shaped structure or an L - shaped structure, and the lower support plate is in a 1 - shaped structure. The lower support plate is arranged on the side far from the airtight protection door of the chute angle steel, and together with the chute angle steel forms a receiving space for inserting and limiting the sliding shaft of the swing rod.
[0010] In some exemplary embodiments, an angular contact spherical plain bearing is provided in the driving output component. The first end of the swing rod is connected to the angular contact spherical plain bearing, and as the angular contact spherical plain bearing rotates, the sliding shaft of the swing rod slides in the chute component to push the sealed protection door to open or close.
[0011] In some exemplary embodiments, the sliding shaft is a needle roller bearing with rollers. The needle roller bearing with rollers is located in the accommodation space and reciprocates in the accommodation space along the slide rail of the chute angle steel to push the sealed protection door to open or close.
[0012] In some exemplary embodiments, when the sealed protection door is closed, the sliding shaft of the swing rod is located at one end of the chute component far from the pivot structure of the sealed protection door.
[0013] In some exemplary embodiments, when the sealed protection door is opened, the sliding shaft of the swing rod is located at one end of the chute component close to the pivot structure of the sealed protection door.
[0014] In the swing rod mechanism of the present application, by providing a driving motor and a driving output component, and driving the swing rod by the driving motor, the sealed protection door can be automatically opened and closed. When the sealed protection door is closed in place, the connection point between the swing arm of the swing rod and the door leaf of the sealed protection door is located at one end far from the pivot axis of the sealed protection door. By adjusting the length of the swing arm of the swing rod, the position of the connection point can be adjusted, effectively avoiding the uneven load on the door leaf of the sealed protection door when closing. In the swing rod mechanism of the present application, the driving structure of the driving motor can be arranged in the door frame wall body, which greatly reduces the space occupied by the overall structure. The overall structure is simple and is beneficial to the installation of equipment. BRIEF DESCRIPTION OF THE DRAWINGS
