The side sliding door with the shaking prevention function comprises a door frame and a door body, the door frame and the door body are rotationally connected through a rotating shaft rod, the door frame is provided with a first single sliding rail and a second single sliding rail which are in rolling fit with the door body, and a supporting position is defined at the lower end of the door body; when the door body is pushed to drive the supporting position of the door body to move along the second single sliding rail, the upper end of the door body moves along the first single sliding rail. Through cooperation of the first single sliding rail, the second single sliding rail, the rotating shaft rod and other structures, in the moving process of the door body, the upper end of the door body and the first single sliding rail are provided with supporting points, and a second supporting point is arranged between the lower end of the door body and the second single sliding rail, so that even if a heavy glass door is used, the door body is not prone to falling off. The phenomenon of shaking does not occur in the moving process; the first single sliding rail and the second single sliding rail do not need to be arranged to be of an existing L-shaped structure, the structure is simple, and the production cost is effectively reduced.

The utility model relates to a steel double-leaf flood-proof door which comprises a door frame, door leaves, an upper bolt clamping mechanism and a lower bolt clamping mechanism, the upper bolt clamping mechanism and the lower bolt clamping mechanism are arranged on the door leaves, a lower doorsill of the door frame is buried in a terrace, and the upper surface of the door frame is flush with the terrace; the upper part of the lower doorsill is provided with a plurality of openings for inserting bolts; the upper and lower bolt clamping mechanism comprises a bolt, a movable sinking water retaining block which moves up and down synchronously with the bolt is fixedly arranged on the bolt, the movable sinking water retaining block is in an L shape, the bottom face of the movable sinking water retaining block can cover the upper surface of the lower doorsill, and a rubber sealing piece is arranged on the side face of the movable sinking water retaining block to be attached to the door leaf. The lower doorsill is pre-buried in the terrace and kept on the terrace, when the plug pin is downwards inserted into the lower doorsill, the L-shaped movable sinking water retaining block moves downwards together, the bottom face of the L-shaped movable sinking water retaining block presses the lower doorsill, meanwhile, the side face of the L-shaped movable sinking water retaining block blocks a door crack in the bottom of the door leaf, and the good sealing and flood preventing functions are achieved.

1. Name of the Design Product: Track Profile (Oblique Drainage Type). 2. Use of the Design Product: Profiles for making door frames, window frames or main structure connectors, as well as other industrial products. 3. Design Key Points of the Design Product: Lies in the shape. 4. Picture or Photograph that Best Illustrates the Design Key Points: Perspective View 1. 5. Other Situations Requiring Explanation: Other Explanation: This product is an indefinite-length product, and the length is drawn using the omission method.

The invention discloses a composite door frame lifting appliance and a using method thereof, and relates to the technical field of lifting, the composite door frame lifting appliance comprises a main frame, a mounting lifting lug is arranged on the side of the main frame, a lifting lifting lug is arranged at the top of the main frame, a plug pin mechanism is arranged in the main frame, and a control module is connected to the plug pin mechanism; the control module is used for controlling the bolt mechanism to operate and enabling the bolt mechanism to be inserted into an inherent pin shaft hole of the door frame, and a horizontal adjusting mechanism is arranged in the main frame and used for adjusting the position of the main frame in the door frame. Hoisting operation is conducted through inherent pin shaft holes of the door frame, the door frame is hoisted through the main frame and the plug pin mechanism, hoisting deformation of the door frame is reduced, the levelness of the door frame is adjusted through the horizontal adjusting mechanism, meanwhile, the hoisted door frame does not need to be temporarily fixed through a supporting piece, and therefore the hoisting efficiency of the door frame is greatly improved.

The utility model discloses an anti-seismic protective air-tight door which comprises a door frame, one side edge in the door frame is connected with a door plate in a rotating mode, an inner groove is formed in the door plate, the middle side wall of the inner groove is fixedly connected with a vertically-erected vertical plate, the two side walls, away from each other, of the vertical plate are evenly and fixedly connected with buffering top plates, and the buffering top plates are of a mutually-staggered structure. The door plate has the following advantages that the inner groove is formed in the door plate, the two rows of buffering top plates are connected in the inner groove through the vertical plates, when the door plate vibrates, the buffering top plates and the buffering sponges can relieve the influence caused by vibration, the buffering effect is good, and the service life of the door plate is prolonged. And due to the fact that the inner groove is formed, the weight of the embedded plate is reduced, damage to the door plate caused by vibration is reduced, auxiliary supporting can be conducted on the door plate through supporting of the buffering top plate, and deformation of the door plate caused by vibration is reduced.
