The pulleys on the sliding door are currently fixed on the sliding door. Although this is convenient for the belt to work with, it can cause noise when the sliding door is pushed and pulled due to uneven installation. It also makes the sliding door move unsteadily. Therefore, it is necessary to design a pulley that can automatically level. Utility Model Content

[0010] As a further description of the above technical solution:

[0011] A reinforcement protrusion is provided on the upper end surface of the mounting seat, and the support shaft passes through the reinforcement protrusion and is slidably connected to the reinforcement protrusion.

[0012] As a further description of the above technical solution:

[0013] A mounting hole is provided on the side end surface of the mounting seat, and the mounting hole is a stepped hole.

[0014] As a further description of the above technical solution:

[0015] A circular groove is formed on the lower end surface of the mounting seat. The diameter of the baffle is smaller than the diameter of the circular groove. The spring is located inside the circular groove.

[0016] Beneficial effects of the utility model:

[0017] The utility model provides a support shaft, a baffle and a spring, so that when the sliding door is installed, if the sliding door is not installed level, the double-groove bearing can move up and down with the cooperation of the support shaft, the baffle and the spring, thereby automatically leveling the pulley, which is conducive to the stable movement of the sliding door and also reduces the noise when the sliding door moves.

[0024] Please refer to the attached Figure 1-3 , wherein, the automatically leveling pulley provided in the embodiment of the present application includes a mounting seat 1, a support shaft 2 is slidably connected inside the mounting seat 1, a double-groove bearing 3 is rotatably connected to the circumferential surface of the support shaft 2, a baffle 9 is fixedly connected to the lower end of the support shaft 2, a spring 8 is provided inside the mounting seat 1, the support shaft 2 is located inside the spring 8, one end of the spring 8 is fixedly connected to the mounting seat 1, and the other end of the spring 8 is fixedly connected to the baffle 9.

[0025] Specifically, when in use, the double-groove bearing 3 is installed on the mounting seat 1 through the support shaft 2, so that the double-groove bearing 3 is not fixedly installed on the mounting seat 1. When the sliding door is installed unevenly, the double-groove bearing 3 can move up and down with the cooperation of the support shaft 2, the baffle 9 and the spring 8, so that the pulley can be automatically leveled, which is conducive to the stable movement of the sliding door and also reduces the noise when the sliding door moves.

[0026] The end face of the support shaft 2 is in a T-shape. During operation, the double-groove bearing 3 can be effectively prevented from separating from the support shaft 2 due to the T-shape of the end face of the support shaft 2 .

[0027] The circumferential surface of the double-groove bearing 3 is provided with a groove 5. During operation, the belt can be limited by the groove 5 provided on the double-groove bearing 3, thereby effectively preventing the belt from escaping from the double-groove bearing 3.

[0028] A reinforcement protrusion 6 is provided on the upper end surface of the mounting seat 1. The support shaft 2 passes through the reinforcement protrusion 6 and is slidingly connected to the reinforcement protrusion 6. During operation, by setting the reinforcement protrusion 6, the support shaft 2 can be limited under the action of the reinforcement protrusion 6, which is conducive to the stable installation of the support shaft 2 on the mounting seat 1.

[0029] A mounting hole 4 is provided on the side end surface of the mounting base 1 , and the mounting hole 4 is a stepped hole. During operation, the mounting base 1 can be conveniently fixed on the sliding door by setting the mounting hole 4 .

[0030] A circular groove 7 is provided on the lower end surface of the mounting seat 1 . The diameter of the baffle 9 is smaller than that of the circular groove 7 . The spring 8 is located inside the circular groove 7 . During operation, the circular groove 7 is provided to facilitate the installation of the spring 8 .
