Description

Technical Field

[0001] The utility model relates to the technical field of lifting sliding doors, and particularly relates to a sliding rail structure of a lifting sliding door. Background Technique

[0002] A lifting sliding door is a special sliding door. It utilizes the principle of lever mechanics and controls the lifting and lowering of the door leaf by rotating a special palm arm, thereby realizing the fixing and opening of the door leaf. This kind of door has better sealing and waterproof performance than ordinary sliding doors.

[0003] The upper sliding rail of the lifting sliding doors on the market is usually integrally designed with the frame body, which is not convenient for the installation of the door leaf. In addition, since the door leaf needs to pass through the rail from the front during installation, in order to avoid excessive friction between the rubber strip and the rail during the installation process, the overlapping amount of the through rubber strip is designed to be very small, which results in poor sealing performance when the door leaf is closed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a sliding rail structure of a lifting sliding door to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A sliding rail structure of a lifting sliding door, including a door frame. One side inside the door frame is embedded with a fixed door leaf. A split structure is installed above the door frame. A sealing structure is fixedly installed below the door frame. A moving door leaf is installed between the split structure and the sealing structure. The fixed door leaf and the moving door leaf are arranged alternately.

[0006] The split structure includes an upper rail. The upper rail is fixedly connected to the top inside the door frame. Upper sliding rail connection components are slidably installed at both the left and right ends inside the upper rail.

[0007] The sealing structure includes a plastic strip. The plastic strip is arranged below the door frame and is located below the moving door leaf. A lower rail is arranged inside the plastic strip. Sealing rubber pads are arranged on both the front and rear outer walls of the plastic strip.

[0008] As a further preference of this technical solution, chutes are opened on both the front and rear sides below the door frame. The lower part of the sealing rubber pad closely adheres to the inside of the chute.

[0009] As a further preference of this technical solution, the upper sliding rail connection component includes two upper sliding rails. An installation block is fixedly connected between the two upper sliding rails. A threaded hole is opened in the installation block. A screw is threadedly connected in the threaded hole.

[0010] As a further preference of this technical solution, a rear mounting plate is threadedly connected to the bottom side of the screw. The rear mounting plate is arranged at the rear side of the movable door leaf. A front mounting plate is arranged below the rear mounting plate. The front mounting plate is arranged at the front side of the movable door leaf. The front mounting plate and the rear mounting plate are connected to the movable door leaf by bolts.

[0011] In the above technical solution, after the movable door leaf is installed on the lower track, the front mounting plate and the rear mounting plate are connected below the upper track by the screw and are connected to the movable door leaf by bolts. Compared with the traditional integral setting, it is not only convenient to disassemble, but also minimizes the wear on the rubber strip during installation, thereby improving the sealing performance.

[0012] As a further preference of this technical solution, a fastening block is threadedly connected to the outer wall of the screw and is located above the rear mounting plate.

[0013] As a further preference of this technical solution, the sealing rubber pads are all made of ethylene propylene diene monomer rubber.

[0014] In the above technical solution, when the movable door leaf sinks to the locked state, the sealing rubber pads on both sides produce elastic deformation with the outer frame of the movable door leaf, so that the lower track and the movable door leaf form a closed state.

[0015] As a further preference of this technical solution, the plastic strip is made of polyvinyl chloride plastic.

[0016] In the above technical solution, the provided plastic strip is made of polyvinyl chloride plastic, which can effectively block the conduction of heat inside and outside the room, thereby playing a heat insulation role and having good heat insulation performance and sealing performance.

[0017] The present utility model provides a lifting sliding door rail structure, which has the following beneficial effects:

[0018] (1) In the present utility model, by providing a split upper track on the movable door leaf, after the movable door leaf is installed on the lower track, the front mounting plate and the rear mounting plate are connected below the upper track by the screw and are connected to the movable door leaf by bolts. Compared with the traditional integral setting, it is not only convenient to disassemble, but also minimizes the wear on the rubber strip during installation, thereby improving the sealing performance.

[0019] (2) In the present utility model, through the provided sealing rubber pads, when the movable door leaf sinks to the locked state, the sealing rubber pads on both sides produce elastic deformation with the outer frame of the movable door leaf, so that the lower track and the movable door leaf form a closed state. The provided plastic strip is made of polyvinyl chloride plastic, which can effectively block the conduction of heat inside and outside the room, thereby playing a heat insulation role and having good heat insulation performance and sealing performance.
