Description

Technical Field

[0001] The utility model patent relates to the technical field of airtight doors, and specifically, to an airtight door sealing control device. Background Art

[0002] A door refers to the entrance and exit of a building or a device installed at the entrance and exit that can be opened and closed. A door is an entity that divides a limited space. Its function is to connect and close the entrances and exits of two or more spaces. As an important part of home decoration and industrial equipment, airtight doors are not only required to have good sealing and sound insulation, but also to be easy to use and highly automated.

[0003] However, the existing airtight doors are sealed by squeezing the wool strips or rubber strips on the door body. As time goes by, the wool strips will age after the door body has been used for a few years, and some of the wool strips will fall off. The elasticity of the rubber strips will obviously decline after a few years of use, resulting in a significant decrease in the sealing effect. Utility Model Content

[0004] The utility model aims to provide a sealing control device for an airtight door, which solves the problem that the sealing performance of the existing airtight door decreases after being used for a long time.

[0005] The utility model is implemented as follows: an airtight door sealing control device comprises a door body frame, a pushing assembly, a slide plate, a slide rail and a telescopic plate, a sliding cavity is provided on the inner side of the door body frame, symmetrically distributed slide rails are provided on the upper and lower sides of the middle end of the sliding cavity, the slide plate is arranged between the two slide rails, and the upper and lower sides of the slide plate are correspondingly slidably connected with the inner sides of the two slide rails, the pushing assembly is arranged at one end of the sliding cavity, and the inner end of the pushing assembly is correspondingly connected with one end of the slide plate, and one side of the slide plate is provided with a plurality of spaced inclined grooves, the upper end of the telescopic plate is arranged at one side of the sliding cavity, and the upper end of the telescopic plate is provided with a plurality of spaced sliding columns, the plurality of sliding columns are correspondingly connected with the inclined grooves on the plurality of sliding plates, and the telescopic plate is slidably connected with the sliding columns inserted in the inclined grooves through the sliding columns.

[0006] Furthermore, the pushing assembly includes a push rod motor, a front end of the push rod motor is correspondingly connected to the inner wall of the sliding cavity, and a rear end of the push rod motor is correspondingly connected to one end of the slide plate.

[0007] The push rod motor pushes the slide plate to slide left and right, and the slide plate slides left and right, driving the inclined groove on the slide plate. The sliding column slides left and right in the inclined groove, pushing the telescopic plate to extend and retract up and down, converting the left and right movement of the motor into the up and down movement of the telescopic plate, thereby achieving the sealing of the door side seam.

[0008] Furthermore, a plurality of open slots distributed at intervals are provided at the rear portion of the upper end of the telescopic plate.

[0009] Furthermore, a sealing strip is provided in each of the opening grooves.

[0010] Furthermore, an opening notch is provided at the lower end of the telescopic plate.

[0011] Furthermore, a lower sealing strip is provided in the opening notch.

[0012] Furthermore, the push rod motor is detachably connected to the door frame via bolts, and the inner end of the push rod motor is detachably connected to one end of the slide plate via bolts.

[0013] Furthermore, a push rod motor controller is provided at the lower end of the door frame, and the push rod motor controller is connected and controlled correspondingly to the push rod motor.

[0014] Compared with the prior art, the utility model provides an airtight door sealing control device with the advantage of automatic lifting. The sliding plate is pushed to slide left and right by the pushing component. The inclined groove on the sliding plate passes through the sliding column inserted on the telescopic plate. The sliding plate drives the sliding column to slide left and right in the inclined groove to realize the up and down movement of the telescopic plate. The sliding column slides in the inclined groove, and the left and right thrust of the push rod motor is evenly converted into up and down thrust. When the telescopic plate is extended, the rubber strip on the telescopic plate is tightly squeezed together with the door frame, thereby realizing the sealing of the gap between the door body and the door frame. On the contrary, by reversing the push rod motor (converting the positive and negative poles of the motor), the telescopic plate is retracted into the inside of the door body frame, which not only reduces the friction between the sealing strip and the (ground) frame, but also reduces the wear of the sealing strip. Manual pushing and pulling of the door body is smoother. Even if the elasticity of the sealing strip is reduced after more than ten years of use, it will not affect the sealing effect, thereby achieving the effect of long-term sealing of the door body.
