Hanging pulley assembly capable of performing lifting regulation by using worm gear and worm

Abstract

The invention relates to a hanging pulley assembly capable of performing lifting regulation by using a worm gear and a worm, and belongs to the manufacturing technology of hardware for daily decoration. In the hanging pulley assembly, a lifting screw is connected below a hanging pulley; a worm gear and a worm are connected below the lifting screw; a worm shaft extends to one end of a hanging box base; the hanging box base is assembled at the upper end of a movable door; a cross screw figure is formed on the end face of a worm extending shaft; and the worm shaft is screwed by a cross screwdriver, so that a covered plastic groove wheel on the lifting screw ascends or descends, and the height of the hanging pulley is regulated effectively. The hanging pulley assembly has the advantages of novel design, reasonable structure, convenient assembly and free regulation. The hanging pulley assembly comprises a hanging pulley (1), a covered plastic groove wheel (4), a lifting regulation hanging box base (5) and a cover plate (6) of the hanging box base, and is characterized in that: a central screw (3) of the hanging pulley is connected with the worm gear (10); the worm gear (10) is connected with the worm shaft (11); the worm shaft (11) is connected with a rotating shaft (12); and a keyseat (12-1) is arranged at the tail end of the rotating shaft (12), and the cross screw figure (13) is formed on the end face.

Description

【Technical field】 [0001] The invention relates to a hardware accessory on a movable door, in particular to an upper-hanging pulley assembly which can be adjusted by a worm gear and a worm, and belongs to the manufacturing technology of daily-use decorative hardware. 【Background technique】 [0002] Mr. Xu Jiangde, the inventor of the patent in Zhongshan City, has been engaged in the research and development of daily decorative hardware products for more than 20 years, and has accumulated rich experience. The implementation of the company has achieved good social and economic benefits. A type of overhead pulley for mobile doors that the company has manufactured and sold for the past few years found difficulty adjusting the height. Generally, there are two moving door leaves of the cabinet body, and the door leaves are arranged horizontally alternately. On the top left and right of a door leaf, a hanging pulley is assembled. There are 4 plastic-coated wheels on the hanging pul...

AI Technical Summary

Problems solved by technology

Therefore, it takes a lot of time to assemble a sliding door, and the workload is also large; because a sliding door weighs tens of kilograms, is 1.4 meters wide, and is more than two meters high, it is difficult for an assembly worker to disassemble it. down and up

Therefore, it takes more manpower
