[0005] Furthermore, the pulley mechanism of this utility model includes a support frame, pulleys, a second side support wheel, and a first side support wheel. The support frame is divided into two plates, front and rear, and two pulleys are installed between the two plates via a rotating shaft. The lower part of the support frame is connected to a movable connecting rod via a rotating shaft and a bushing. The movable connecting rod is connected to a fixed block via a rotating shaft and a bushing. The fixed block is installed on the upper part of the sliding door with screws.

[0006] Furthermore, the slide rail of this utility model includes an L-shaped base and a track. The L-shaped base is fixedly installed on the upper part of the cavity flange of the sliding door, and the track is fixedly installed on the front part of the L-shaped base. The pulley moves back and forth on the track.

[0007] Furthermore, the rear of the support frame of this utility model is equipped with a side support wheel 1 via a bracket, and the front of the support frame is equipped with a side support wheel 2 via a bracket. The side support wheel 1 moves back and forth on the surface of the cavity flange, and the side support wheel 2 moves back and forth on the surface of the L-shaped base.

[0008] Furthermore, the pulley surface of this utility model is concave.

[0009] Furthermore, the lower part of the sliding door of this utility model is fixedly installed with a sliding component by a bracket.

[0010] Furthermore, the sliding component of this invention is a follower wheel or a follower slider. Compared with the prior art, this utility model can effectively improve the stability of the sliding door by adding a second side support wheel and a first side support wheel, as well as a pulley with a concave surface, to the pulley mechanism of the sliding door, and by using a sliding groove and a sliding component for limiting, which can effectively prevent the sliding door from shaking.

[0012] The present invention will be further described below with reference to the accompanying drawings.

[0013] like Figure 1 and Figure 2 As shown, a sliding sealing door mechanism includes a sealing cavity 1, a cavity flange 11, a pulley mechanism 2, a support frame 21, pulleys 22, a second side support wheel 23, a movable connecting rod 24, a first side support wheel 25, a sliding assembly 3, a slide rail 4, an L-shaped base 41, a track 42, a sliding groove 5, and a sliding door 6. The cavity flange 11 is located at the opening of the sealing cavity 1. The slide rail 4 is fixedly installed on the upper part of the cavity flange 11, and the sliding groove 5 is fixedly installed on the lower part of the cavity flange 11. The sliding door 6 moves left and right within the slide rail 4 and the sliding groove 5 via the pulley mechanism 2 and the sliding assembly 3. When the pulley 22 rolls along the track 42, the second side support wheel 23 and the first side support wheel 25 roll along the side of the cavity flange 11 from the L-shaped base 41, thereby improving the stability of the pulley mechanism 2. To further enhance stability, two or more pulleys 22 can be arranged in parallel on the pulley mechanism 2.

[0014] Furthermore, such as Figure 3 and Figure 4As shown, the pulley mechanism 2 of this utility model includes a support frame 21, pulleys 22, a second side support wheel 23, and a first side support wheel 25. The support frame 21 is divided into front and rear plates, with two pulleys 22 mounted on the front and rear plates via a pivot. The lower part of the support frame 21 is connected to a movable connecting rod 24 via a pivot and a bushing. The movable connecting rod 24 is connected to a fixed block via a pivot and a bushing. The fixed block is mounted on the upper part of the sliding door 6 with screws. The first side support wheel 25 is mounted on the rear of the support frame 21 via a bracket, and the second side support wheel 23 is mounted on the front of the support frame 21 via a bracket. The first side support wheel 25 moves back and forth on the surface of the cavity flange 11, and the second side support wheel 23 moves back and forth on the surface of the L-shaped base 41. The surface of the pulley 22 of this utility model is concave.

[0015] Furthermore, such as Figure 4 As shown, the slide rail 4 of this utility model includes an L-shaped base 41 and a track 42. The L-shaped base 41 is fixedly installed on the upper part of the cavity flange 11 of the sliding door 6, and the track 42 is fixedly installed on the front part of the L-shaped base 41. Two pulleys 22 move back and forth on the track 42.

[0016] This invention improves the stability of the sliding door by setting the coating chamber into multiple partitioned chambers and by adding side support wheels 23 and 25, as well as concave pulleys 22 to the pulley mechanism 2 of the sliding door 6, in conjunction with the sliding groove 5 and the sliding component 3 for limiting.

[0017] The above embodiments are not limited to the specific application functions of the sliding sealing door mechanism. Within the scope of implementation, the functions of each component can be freely set to meet the work requirements and complete the corresponding work process, which greatly improves the stability of the vacuum coating equipment.
