Description

Anti-seize guide pulley

[Technical Field]

The invention relates to a guide pulley.

【Background technique】

A guide pulley is used on the sliding door pages such as the shower room and the closet door to help the door slide open. The weight of the door is large. In order to prevent the door from swaying, the balance guide pulley is usually used, that is, the runner is arranged on both sides, and the runners on both sides slide on the two parallel guide rails. In the prior art, all the runners have the same outer dimensions and are symmetrically arranged. In order to prevent the sway, the runners slide on the guide rails. Due to the long-term bearing of the guide rails, some bending deformation will inevitably occur. Deformation, the distance between the two guide rails will be widened or narrowed, but the distance between the two runners will not change, so the runner will be stuck, resulting in a smooth opening of the door.

[Summary of the Invention]

SUMMARY OF THE INVENTION It is an object of the present invention to overcome the deficiencies of the prior art and to provide a self-locking guide pulley having a simple structure.

In order to solve the above problems, the present invention adopts the following technical solutions:

An anti-seize guide pulley, comprising a pulley mounting block, wherein two sides of the pulley mounting block are respectively rotatably provided with a first rotating wheel and a second rotating wheel, the outer circumference of the first rotating wheel a first guiding slot is arranged on the first rail, and a second guiding slot sliding on the second rail is disposed on the outer circumference of the second rotating wheel, wherein: the first The width of the guide slot is greater than the width of the second guide slot.

An anti-seize guide pulley as described above, characterized in that: the width of the first guide chute is larger than the width of the second guide chute by 3-15 mm.

An anti-seize guide pulley as described above, characterized in that: the pulley mounting block is provided with a mounting upper cover and a mounting lower cover which is covered with the mounting upper cover, the mounting upper cover And installing a lower cover to form a center cavity, wherein the center cavity is provided with a ball, the ball is provided with a rotating shaft, and the two ends of the rotating shaft are respectively inserted into the first rotating wheel and the second rotating wheel Inside.

An anti-seize guide pulley as described above, characterized in that: the two side walls of the pulley mounting block are provided with a receiving slot, and the first rotating wheel and the second rotating wheel are disposed on the Inside the containment tank.

An anti-seize guide pulley as described above, characterized in that: a central mounting hole is arranged in a middle portion of the pulley mounting block, and the first rotating wheel and the second rotating wheel are provided in two groups, respectively On both sides of the center mounting hole.

The beneficial effects of the present invention are: since the width of the first guiding slot is larger than the width of the second guiding slot, that is, the width of the two guiding grooves is different, the second guiding slot can match the size of the second guiding rail, and the first guiding slip The width of the groove is larger than the width of the first guide rail, so that a certain adjustment space is given. After the guide frame of the guide rail is deformed, the second rotating wheel does not move, and the first rotating wheel is automatically adjusted in the width direction of the first guiding slot to prevent two The runners are stuck; the two ends of the rotating shaft are inserted into the runner, and then the upper cover and the lower cover are assembled to complete the installation, the structure is simple, and the installation is convenient; the two side walls of the pulley mounting block are arranged The container is used to accommodate the runner, so as to achieve a hidden effect and a beautiful appearance.

【detailed description】

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

As shown in FIG. 1 to FIG. 4, an anti-seize guide pulley includes a pulley mounting block 1, and two sides of the pulley mounting block 1 are rotatably provided with a first reel 2 and a second reel 3, respectively. a rotating wheel 2 and a second rotating wheel 3 are on both sides of the pulley mounting block 1, and the pulley mounting block 1 is sandwiched therebetween. The two side walls of the pulley mounting block 1 are provided with a receiving groove 9, a first rotating wheel 2 and The second rotating wheel 3 is disposed in the receiving slot 9, and the center of the pulley mounting block 1 is provided with a central mounting hole 10, and the first rotating wheel 2 and the second rotating wheel 3 are provided with two groups, which are respectively disposed in the central mounting hole 10. On both sides, the two sets of runners are symmetrically arranged with the central mounting hole 10 as a symmetrical center. A first guide chute 21 sliding on the first guide rail 4 is disposed on the outer circumference of the first reel 2, and a second guide chute sliding on the second guide rail 5 is disposed on the outer circumference of the second revolver 3. 31. The width of the first guiding slot 21 is greater than the width of the second guiding slot 31, that is, the width of the first guiding slot 21 and the width of the second guiding slot 31 are not equal, and the width of the first guiding slot 21 is greater than the second. The width of the guide chute 31 is 3-15 mm. In the figure, the width of the first guide chute 21 is represented by d1, the width of the second guide chute 31 is represented by d2, the width of the first guide rail 4 and the second guide rail 5 are the same, and the width of the second guide rail 5 and the second guide chute 31 Corresponding to the width dimension, the second guiding slot 31 is substantially unable to sway on the second guiding rail 5; and the width of the first guiding slot 21 is significantly larger than that of the first guiding rail 4, and the first guiding slot 21 can be provided on the first guiding rail 4 There is a certain amount of swing space. When the guide rail frame is deformed, that is, the distance between the first rail 4 and the second rail 5 is changed, the first guide chute 21 is automatically adjusted in the width direction of the first rail 4, thereby ensuring that neither runner is stuck. dead.
