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 Figure 1-Figure 4 The utility model provides a technical solution: a furniture pulley with an adjustment function, comprising a guide wheel plate 1 and an adjustment chamber 2 fixedly arranged on the guide wheel plate 1, an upper dust cover 6 fixedly arranged on the outer surface of the adjustment chamber 2; a guide block 3 for driving the pulley to move is slidably arranged on one side of the guide wheel plate 1, and a lower dust cover 7 is fixedly arranged on the outer surface of the guide block 3; an adjustment elastic member 4 is arranged between the adjustment chamber 2 and the guide block 3, and the adjustment elastic member 4 is a spring, and its elastic coefficient can be set according to demand, and in the initial state, the adjustment elastic member 4 is in a compressed state (such as Figure 2 The adjusting chamber 2 is provided with a locking structure 5 for locking the position of the guide block 3, thereby locking the position of the pulley.

[0022] For the specific structure of the guide wheel plate 1, please refer to the reference patent A furniture pulley (publication number CN205778122U, publication date 2016-12-07).

[0023] Among them, regarding the installation scheme of the guide block 3, the guide plate 8 is symmetrically fixedly arranged on the guide wheel plate 1, and the outer surface of the guide block 3 and the inner surface of the guide plate 8 are slidably arranged, thereby improving the stability of the pulley during the movement.

[0024] The locking structure 5 includes a limit rod 501 fixedly arranged on the top of the guide block 3, and a locking rod 502 is slidably arranged inside the adjustment chamber 2, wherein the locking rod 502 can be engaged with the limit rod 501. When the locking rod 502 can be disengaged from the limit rod 501, the adjustment elastic member 4 can drive the guide block 3 to move in the vertical direction to adjust the position of the pulley. When the pulley moves to the specified position, the locking rod 502 continues to be engaged with the limit rod 501, thereby locking the position of the guide block 3. At this time, the pulley position adjustment is completed.

[0025] As a further technical solution, an adjusting knob 503 is rotatably provided on the upper dust cover 6, wherein the locking rod 502 is driven to move in the horizontal direction by rotating the adjusting knob 503, and is disengaged from or engaged with the limiting rod 501. A plurality of locking blocks 504 are fixedly provided on opposite sides of the limiting rod 501 and the locking rod 502, and the locking blocks 504 on the limiting rod 501 and the locking rod 502 are staggered, so that the locking blocks 504 on the limiting rod 501 and the locking rod 502 can be engaged with each other, thereby limiting and locking the position of the limiting rod 501 through the locking rod 502.

[0026] As a further technical solution, an adjustment slot 505 is provided on one side of the adjustment knob 503, and an adjustment column 506 is fixedly provided on one side of the locking rod 502, wherein the end of the adjustment column 506 extends into the adjustment slot 505. The adjustment slot 505 is driven to rotate by rotating the adjustment knob 503, and due to the position limitation of the locking rod 502, the locking rod 502 is driven to move in the horizontal direction under the cooperation of the adjustment slot 505 and the adjustment column 506, so that the locking rod 502 is close to or away from the limiting rod 501, and the locking state of the limiting rod 501 is regulated.

[0027] As a further technical solution, a limiting groove 507 is provided on the inner side of the upper dust cover 6, and a limiting block 508 is fixedly provided on one side of the locking rod 502, wherein the outer surface of the limiting block 508 is slidably provided with the inner surface of the limiting groove 507, and as a preferred solution, a limiting spring is fixedly provided between the limiting block 508 and the inner wall of the limiting groove 507, and the elastic coefficient of the limiting spring is greater than the elastic coefficient of the adjusting elastic member 4, so that the stability of the locking rod 502 is improved after the locking rod 502 is engaged with the limiting rod 501. By the coordinated arrangement of the limiting groove 507 and the limiting block 508, the moving direction of the locking rod 502 is limited, and its stability during the movement is improved.
