When the synchronous belt adjusting device is used, by rotating the adjusting screw 201, because the inner wall of the guide hole 1013 is provided with the internal thread, when the adjusting screw 201 is rotated, the adjusting screw 201 moves relative to the mounting end 101, because the adjusting screw 201 is connected with the adjusting sleeve 202, the adjusting sleeve 202 is connected with the belt pulley 13, and the adjusting sleeve 202 is movably arranged at the corresponding mounting end 101, when the adjusting screw 201 moves relative to the mounting end 101, the belt pulley 13 is synchronously driven to move through the adjusting sleeve 202, and when the belt pulley 13 moves, the tightness adjustment of the synchronous belt 12 can be realized.

Further, as shown in fig. 2 in conjunction with fig. 1, a waist-shaped hole 1011 is formed on a side of the mounting end 101 facing away from the door 11 along a moving direction of the pulley 13, and a guide groove 1014 is formed on a side of the mounting end 101 facing toward the door, and the guide groove 1014 communicates with the waist-shaped hole 1011; when the adjusting sleeve 202 is installed in the guide slot 1014, one end of the adjusting sleeve 202 is located in the guide slot 1014, the other end is located in the waist-shaped hole 1011, and the adjusting screw 201 can drive the adjusting sleeve 202 to move relative to the waist-shaped hole 1011.

Specifically, as shown in fig. 2 in combination with fig. 4 and 5, the adjusting sleeve 202 includes a first boss 2021 and a second boss 2022, which are coaxially disposed, and the diameter of the first boss 2021 is greater than that of the second boss 2022, the first boss 2021 is located in the guiding groove 1014, and the second boss 2022 is located in the waist-shaped hole 1011;

meanwhile, a first threaded hole 2023 is formed in the first boss 2021 in the axial direction of the adjusting screw 201, a second threaded hole 2024 is formed in the second boss 2022 in the axial direction of the pulley, the adjusting screw 201 penetrates through the mounting end 101 and then extends into the first threaded hole 2023, the pulley 13 comprises a synchronous pulley 131, a bolt 132 and a shaft sleeve 133, the shaft sleeve 133 is located between the synchronous pulley 131 and the mounting end 101, and the bolt 132 sequentially penetrates through the synchronous pulley 131 and the shaft sleeve 133 and then extends into the second threaded hole 2024 and then is connected with the second boss 2022.

When the synchronous belt adjusting device is used, as shown in fig. 5, by rotating the adjusting screw 201, the adjusting screw 201 drives the first boss 2021 to move in the guide groove 1014, the first boss 2021 drives the second boss 2022 to move in the waist-shaped hole 1011, and since the belt pulley 13 is connected to the second boss 2022, when the second boss 2022 moves relative to the waist-shaped hole 1011, the belt pulley 13 can be driven to move, so that the purpose of adjusting the synchronous belt 12 is achieved.

In some embodiments, to avoid rotation of the second boss 2022 when it moves in the guide slot 1014, as shown in fig. 4, flat surfaces 20111 are disposed on opposite sides of the first boss 2021, and the distance between the two flat surfaces 20111 corresponds to the slot width of the guide slot 1014.

Since the distance between the two flat surfaces 20111 corresponds to the width of the guide groove 1014, when the first boss 2021 is located in the guide groove 1014, the flat surface 20111 on the first boss 2021 contacts the inner wall of the guide groove 1014, so that the first boss 2021 can only move linearly under the mutual restriction of the flat surface 20111 and the inner wall of the guide groove 1014.
