Detailed Description
The technical solution of the present patent will be described in further detail with reference to the following embodiments.
In the description of the present invention, it should be noted that the terms "inside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are only for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and operate, and thus, should not be construed as limiting the present invention.
As shown in fig. 1 to 3, the mechanical handle airtight door includes a door frame 10 and a door body 12 connected to the door frame 10, wherein one side of the door frame 10 is pivotally connected to the door body 12. Two symmetrical handles 14 are arranged on two sides of the door body 12. The inside of the door body 12 is provided with a driving gear 16, a driven gear 18 and a rack 20, the two handles 14 are respectively connected with the driving gear 14, the driving gear 16 is connected with the driven gear 18, and the driven gear 18 is meshed with the rack 20 which can extend out of the door body 12. The door frame 10 is provided with an opening into which the rack 20 can be inserted, when the door frame is used, the handle 14 is pressed down, the handle 14 drives the driving gear 16 to rotate, the driving gear 16 is meshed with the driven gear 18, the driven gear 18 is meshed with the rack 20, and when the handle 14 is pressed down, the rack 20 can be pushed into the door frame 10 from the opening to close the door body 12. The door body 12 is further provided with a sealing rubber strip 24 for sealing with the door frame 10, and the door body 12 is provided with a groove 26 for placing the sealing rubber strip 24. The door frame 10 is provided with a convex edge 28 which corresponds to the position of the groove 26 and can be inserted into the groove 26, when the door body 12 is closed, the convex edge on the door frame 10 can be inserted into the groove 26, and because the sealing rubber strip is arranged in the groove 26, the door frame can be further sealed.
Further, one end of the rack 20 is provided with a wedge-shaped surface 22, the wedge-shaped surface 22 faces the door opening direction of the door body 12, the wedge-shaped surface 22 of the rack 20 enters the door frame 10 through the opening during use, and due to the fact that the wedge-shaped surface 22 is extruded when being inserted into the door frame, force towards the closing direction of the door body 12 can be received, the door body 12 and the door frame 10 can be close to and tightly closed, meanwhile, the groove 26 and the sealing rubber strip 24 on the door body 12 also extrude the convex edge on the door frame 10, and an acting force is given to the convex edge to enable the door body 12 and the door frame 10 to be attached and further sealed.
