A pulley with brake structure

Abstract

The invention discloses a sliding wheel with a braking structure. The sliding wheel with the braking structure comprises a hanging plate and a sliding concave wheel rotationally connected to the plate face of the hanging plate and further comprises a brake, wherein the brake and the sliding concave wheel are arranged on the same hanging plate; the brake comprises an installing box fixed to the hanging plate through cooperation of rivets and a shaft sleeve, and a friction block hung on the shaft sleeve and capable of sliding up and down; a sliding piece capable of sliding up and down on the inner side of the installing box, and a rotating piece are arranged above the friction block, and one end portion of the rotating piece is connected in the installing box in a hinged manner and can rotate; the rotating piece rotates around the hinged end portion so that the sliding piece can push the friction block to slide downwards to collide with and rub the sliding concave wheel; in this way, the speed of the sliding wheel can be controlled by controlling rotation of the rotating piece; use of the sliding wheel is safer; and the sliding wheel is simple in structure and low in manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of furniture, in particular to a pulley with a braking structure. Background technique [0002] In today's furniture field, many furniture have movable parts: the cabinet door of the wardrobe has changed from a swing door type to a push-pull type. body; while the slide rail connection usually installs pulleys on the door panel so that the door panel can move efficiently on the slide rail, see the attached figure 1 Shown is the existing furniture pulley structure, which mainly includes a long plate 11, a first concave wheel 1a, a second concave wheel 1b, and a plastic block 12. It can be seen that the existing pulley structure lacks a buffer braking device, resulting in fluctuations in the moving speed of the cabinet door. Uncontrollable phenomenon, so easy to make the cabinet door move too fast and cause the cabinet door to quickly collide with the cabinet body, causing damage and bruising and pinching the ...

[0002] In today's furniture field, many furniture have movable parts: the cabinet door of the wardrobe has changed from a swing door type to a push-pull type. body; while the slide rail connection usually installs pulleys on the door panel so that the door panel can move efficiently on the slide rail, see the attached figure 1 Shown is the existing furniture pulley structure, which mainly includes a long plate 11, a first concave wheel 1a, a second concave wheel 1b, and a plastic block 12. It can be seen that the existing pulley structure lacks a buffer braking device, resulting in fluctuations in the moving speed of the cabinet door. Uncontrollable phenomenon, so easy to make the cabinet door move too fast and cause the cabinet door to quickly collide with the cabinet body, causing damage and bruising and pinching the user. It requires the user to push and pull the cabinet door with an appropriate force, which brings inconvenience to the user and reduces the user experience.
