[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model independently designs the transmission rod and the pulley block to be linked, and the working state of the pulley block is operated by the handle through the lever principle; when the pulley is under force, the door leaf can be pushed to move on the track, and when it is not under force, the door leaf falls on the surface of the door frame and remains stationary.

[0013] 2. The utility model uses the pulley block to bear stress for a long time, so that the stress is only applied when the door leaf is opened. When the door leaf is closed or stops running, the handle transmission box is operated to make the door leaf sink and fall on the door frame, thereby reducing the load on the pulley and increasing the service life of the pulley.

[0014] 3. The utility model designs the bottom wool strip of the door leaf as a rubber pad. After the door leaf is closed, the door leaf is sunk by operating the handle transmission box. At the same time, the door leaf profile squeezes the bottom rubber pad, so that the sliding door and window have a sealing effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a high-airtight sliding door hardware device, including a transmission rod 1 and a pulley block 3. A handle transmission box 11 is installed on one side of the transmission rod 1. The handle transmission box 11 is a switch operating component of doors and windows commonly used in the prior art, which is connected to the handle and the locking system. The mechanical elements in the transmission box are driven by rotating the handle to achieve the opening and closing of the doors and windows.

[0022] A turnbuckle 12 is inserted on the transmission rod 1, and the turnbuckle 12 is inserted into the door and window parts, which are not shown in the accompanying drawings. The door and window parts include door leaves and door frames. The bottom of the transmission rod 1 is connected to a linkage mechanism 2, which is hinged to the pulley block 3. The linkage mechanism 2 includes a tail connector 21, which is fixedly connected to the bottom of the transmission rod 1. The bottom of the tail connector 21 is hinged with a triangular block connector 22, and a connecting rod 23 is hinged at one corner of the triangular block connector 22, and a main wheel frame 6 is hinged at the other corner of the triangular block connector 22.

[0023] The pulley block 3 includes a pulley accessory 31, which is hinged to the connecting rod 23. The transmission rod 1 and the pulley block 3 are independently designed to be linked, and the working state of the pulley block is operated by the handle transmission rod 1 through the lever principle; the pulley 32 can push the door leaf to move on the track when it is under force, and the door leaf falls on the surface of the door frame and remains stationary when it is not under force.

[0024] The tail connector 21, the triangular block connector 22 and the connecting rod 23 work together to convert the linear motion of the transmission rod 1 into the specific motion required by the pulley block 3. The pulley block 3 is subjected to long-term force only when the door leaf is opened. When the door leaf is closed or stops running, the handle transmission box 11 is operated to make the door leaf sink and fall on the door frame, thereby reducing the load on the pulley 32 and increasing the service life of the pulley 32.

[0025] A pulley 32 is rotatably connected to the pulley accessory 31, a pulley connecting rod 5 is fixedly connected between the two pulley groups 3, the main wheel frame 6 is an "L"-shaped structure, and a rubber pad 4 is bonded to the bottom of the main wheel frame 6. The rubber pad 4 is an elastic sealing strip structure, and the bottom sealing structure adopts an elastic sealing strip, which is embedded in the bottom of the door leaf to form a seal when it contacts the ground.

[0026] Both sides of one side of the main wheel frame 6 extend to form a baffle structure and limit the tail connecting piece 21 , and the pulley fitting 31 limits the two sides of the rubber pad 4 .

[0027] In short, through the rotation of the handle transmission box 11, the transmission rod 1 can drive the linkage mechanism 2, thereby driving the pulley block 3 and other components to work. The handle transmission box 11 and the bottom pulley block 3 can work in conjunction, and at the same time use the lever principle to achieve the sinking of the door leaf and cooperate with the rubber pad 4 to achieve a sealing effect.
