Description

Self-balancing pulley

[Technical Field]

The invention relates to a pulley.

【Background technique】

Pulleys are used on sliding door pages such as shower rooms and closet doors to help the door slide open. The weight of the door is large. In order to prevent the door from swaying, more than two wheels are usually used to assist the rotation. However, in order to make the door slide smoothly, all the wheels need to rotate on the same surface when rotating, if there is a high or low Uneven, then the door page will follow the instability, it will produce noise, etc., bringing certain hidden dangers.

In addition, in order to prevent the door sway, two parallel guide grooves are usually used to carry the weight of the door leaf, and then the wheels are arranged on both sides of the pulley, and each of the wheels respectively slides in the guide groove on the corresponding side. In order to make the door sliding smoothly, the guide grooves on both sides must be parallel and always maintain the same height. However, after long-term use, the guide groove is not subjected to the same gravity or deformation, which causes the door to slide easily or sway when sliding. . When some existing balance pulleys are adjusted, the structure is complicated and the adjustment is not convenient.

【detailed description】

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

Embodiment 1, as shown in FIG. 1 to FIG. 5, a self-balancing pulley includes a mounting block 1 on a side of which a balance piece 2 is hinged by a hinge shaft 10, and the balance piece 2 is along the length direction of the mounting block 1. Abutting on the side of the mounting block 1, the balance plate 2 is respectively provided with a rotating wheel 3 on both sides of the hinge shaft 10. The rotating wheel 3 can be rotated around the hinge shaft 10 at both ends of the balancing piece 2, and the principle is similar to the seesaw. The mounting block 1 is provided with a limit blocking portion 18 which can block the rotation of the balance piece 2. After the balance piece 2 is swung, it is blocked by the limit blocking portion 18 to prevent excessive swinging. The balance piece 2 is provided with two pieces, the two pieces of the balance piece 2 are perpendicular to the sliding direction of the mounting block 1, the two pieces of the balance piece 2 are sandwiched by the mounting block 1, and the balance piece 2 is disposed at the opposite of the mounting block 1. On the side, each balance piece 2 is provided with a runner 3, and in the embodiment, two turns are arranged on the balance piece 2. The wheel 3, the balance piece 2 has a "several" shape, and the runner 3 on one balance piece slides in a guide groove. When the unevenness occurs in the same guide groove, the two runners 3 on the balance piece 2 are on the door page. Under the action of gravity, it swings around the hinge shaft 10 to achieve automatic balance, so that the door page slides smoothly.

The mounting block 1 is provided with a mounting cavity 13 in the middle of the mounting block 13. The rotating column 4 is disposed in the mounting cavity 13 so as to be rotatably disposed in the mounting cavity 13. The rotating shaft of the rotating column 4 is parallel to the sliding direction of the mounting block 1, and the mounting block is installed. 1 is provided with a mounting hole 14 communicating with the mounting cavity 13, and the mounting block 1 is further provided with a pendulum 15 inserted from the mounting hole 14 into the rotating column 4, and the pendulum column 15 is extended from the mounting hole 14 and connected to the door page The size of the opening of the mounting hole 14 limits the swinging amplitude of the pendulum column 15 to prevent the pendulum column 15 from excessively swinging, so that the pendulum column 15 will rotate the rotating column 4 to swing in the direction of the balance plates 2 on both sides, when the two guides When the height of the chute is inconsistent, under the action of the gravity of the door page, the rotating column 4 will rotate and swing, thereby adjusting the height of the rotating wheel 3 of the two balance pieces 2, that is, adjusting the height of the rotating wheel 3 in the two guiding chutes, so that two The runners 3 in the guide chutes are substantially flush, ensuring a smooth sliding of the door pages. A nut groove 41 is disposed in the rotating column 4, and the nut groove 41 is provided with a nut 42 for inserting and screwing the pendulum column 15. The screw 4 is provided with a thread and is connected by a nut 42 for easy installation.

The second embodiment, as shown in FIG. 6 to FIG. 8 , is different from the first embodiment in that the balance piece 2 is provided with four pieces, and the left end 11 and the right arm 12 are extended at two ends of the mounting block 1 , and four balance pieces 2 are arranged. They are respectively disposed on two opposite sides of the left arm 11 and the right arm 12, and each balance piece 2 is provided with two runners 3, so that there are eight runners 3, and the runners 3 on the same side are located in the same guide roller. In the slot, since there are many runners, if four sets are placed on one balance piece 2, the balance piece 2 will be too long and the amplitude will be large when swinging. Therefore, the same side is divided into two pieces. a left gasket groove 16 is disposed on two opposite sides of the left arm 11, and a right gasket groove 17 is disposed on opposite sides of the right arm 12. The two sides of the mounting block 1 are provided with a mounting gasket 5, and the gasket 5 is mounted. The two ends project into the left gasket groove 16 and the right gasket groove 17, respectively, and the balance piece 2 abuts against the outer wall of the mounting gasket 5. Since the balance sheets 2 on the same side are provided separately, in order to secure the strength of the mounting block 1, a mounting spacer 5 is attached to the side of the mounting block 1.
