Abstract
Description
- The present invention relates to a pulley device with anti-sticking function.
- A pulley device is widely used on sliding door leaf such as in shower rooms or in closet doors of the state of art to assist the door leaf to be opened by sliding. In some cases, the weight of the door leaf is large. In order to prevent door leaf shaking, balance pulley devices are employed to assist a door leaf to slide smoothly, that is, the pulleys are arranged on both sides, and the pulleys on both sides slide on two parallel guide rails. In the prior art, the pulleys have the same size and symmetrical shape, which are arranged symmetrically. In order to prevent the sway, the pulleys clamp on the guide rails for sliding. Due to the long-term bearing of door leaf or the like, some bending deformation will inevitably occur to the guide rails. Once the guide rails shape, the distance between the two guide rails will be widened or narrowed. However, the distance between the two sides of pulleys will not change, so the pulleys will be stuck, preventing a smooth sliding of the door.
- In order to overcome the deficiencies in the prior art, the present invention intends to provide an anti-sticking pulley device with a simple structure.
- In order to solve the above problems, the present invention adopts the following technical solutions:
- An anti-sticking pulley device comprises a pulley mounting block; a first pulley and a second pulley, being mounted on two sides of the pulley mounting block; a first guide groove, being disposed around the outer circumference of the first pulley, wherein the first pulley can slide on a first guide rail; and a second guide groove, being disposed around the outer circumference of the second pulley, wherein the second pulley can slide on a second guide rail; wherein the width of the first guide groove is wider than the width of the second guide groove.
- According to the present invention, the width of the first guide groove is wider than the width of the second guide groove by 3-15 mm.
- According to the present invention, the pulley mounting block is provided with an upper mounting cover and a lower mounting cover which is mounted under the upper mounting cover; the upper mounting cover and the lower mounting cover are mounted to form a circle cavity; balls are arranged in circle cavity; a rotating shaft is arranged on the balls; the two ends of the rotating shaft are inserted into the first pulley and the second pulley respectively.
- According to the present invention, each of the two side walls of the pulley mounting block is provided with a receiving groove for receiving the first pulley and the second pulley.
- According to the present invention, a central mounting hole is provided in a middle portion of the pulley mounting block; two groups of the first pulley and the second pulley are provided, which are respectively placed on both sides of the central mounting hole.
- The utility model has the following advantages: since the first guide groove is wider than the width of the second guide groove, in other words, the width of the two guiding grooves is different, the second guide groove can match the size of the second guide rail, and the width of the first guide groove is larger than the width of the first guide rail, so that a certain adjusting space is kept. When the guide frame of the guide rail is shaped, the second pulley does not move, while the first pulley is adjusted automatically in the width direction of the first guide groove to prevent the two pulleys from being stuck. The two ends of the rotating shaft are inserted into the pulleys, 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 provided with a receiving groove for receiving the first pulley and the second pulley, so as to achieve a hidden effect and a beautiful appearance.
