Abstract

The invention discloses a curtain brake head comprising a brake head seat and a brake head cover connected with the brake head seat. A cavity is formed in the brake head seat; a chain wheel is arranged in the inner cavity, one end of the chain wheel is rotationally connected with the brake head cover, and a central gear is arranged at the other end of the chain wheel and connected with a planet gear system; the other end, opposite to the chain wheel, of the planet gear system is connected with a clutch cover, and a clutch shaft is arranged at the other end of the clutch cover; a rotating shaft is arranged at the end, away from the clutch cover, of the clutch shaft, and penetrates through the inner cavity through the brake head seat; a plurality of gaps are reserved between the clutch cover and the clutch shaft as well as between the clutch shaft and the rotating shaft, and rollers are arranged in the gaps. According to the curtain brake head, in working, the chain wheel drives the planet gear system to rotate, accordingly a clutch drives a curtain to rise and fall; stable braking and self-locking functions are achieved; all the parts are in clearance fit, the requirement for precision is reduced, and the production efficiency is improved; and the curtain brake head is used for the field of curtain brake heads.

Description

technical field [0001] The invention relates to the field of curtain accessories, in particular to a curtain head. Background technique [0002] The existing curtain head products mainly rely on the torsion spring to realize the brake self-locking function, which requires relatively high machining accuracy and assembly accuracy of the parts. A slight error will have a significant impact on the load of the head and directly affect the use. sense of experience. In the production process, high precision requirements directly reduce production efficiency and increase production costs. Contents of the invention [0003] The object of the present invention is to provide a curtain head with stable braking and self-locking effects, good hand feeling, and simple and convenient production, assembly and installation. [0004] The technical scheme that the present invention takes is: [0005] A curtain head, comprising a head base and a head cover connected with the head base, an i...
