The improved handle comprises a base, a rotary shaft hole is formed in the middle of the base, a rotary shaft is arranged in the rotary shaft hole in a rotary mode, a hand shank and a square shaft are arranged at the upper end and the lower end of the rotary shaft respectively, a handle fixing component and a locating piece enabling the square shaft to be in different rotating states are arranged on the base, two handle locating grooves are formed in the bottom face of the base at intervals, a transverse locating screw hole communicated with the right handle locating groove is formed in the right side wall of the base, the handle fixing component comprises a set screw and two sets of handle fixing screws and handle fixing sleeve seats, the two handle fixing screws are arranged in the handle fixing sleeve seats respectively in a sleeved mode, the two handle fixing sleeve seats are arranged in the handle locating grooves respectively in a sleeved mode, a clamping groove is formed in the outer wall of the right handle fixing sleeve seat, a concave ring is arranged on the inner wall of the left handle locating groove, a protruding ring is arranged on the outer wall of the left handle fixing sleeve seat, the left end of the set screw is clamped in the clamping groove, the protruding ring is forced to be clamped in the concave ring in the process that the set screw is screwed in the clamping groove.

Description

technical field [0001] The invention relates to a door and window handle, in particular to an improved door and window handle with simple structure, convenient installation and disassembly, more beautiful appearance and greatly improved handle life. Background technique [0002] At present, there are many kinds of handles used for swinging doors and windows, but their structural principles are basically the same. The handle generally includes a base, a rotating shaft, a handle, a square shaft and a positioning piece. It is used for fixed installation on doors and windows. One end of the rotating shaft is fixedly connected to the handle, and the other end is fixedly connected to the square shaft. The positioning piece is installed between the base and the rotating shaft. Requirements for the use of hand rotary switches. [0003] However, the traditional handles use the spring to directly contact the rotating shaft, and use the elastic support of the spring to stabilize the r...

AI Technical Summary

Problems solved by technology

[0003] However, the traditional handles use the spring to directly contact the rotating shaft, and use the elastic support of the spring to stabilize the rotation state of the square shaft. Since the spring is in direct contact with the square shaft, and there are metal parts between the two, it will cause The wear between the two is relatively large, which greatly reduces the service life of the handle; in addition, the friction noise between the spring and the square shaft is also relatively large, making the traditional handle unable to meet the needs of modern life; The base must be equipped with handle fixing parts and actuator fixing parts, while the traditional handle is directly opened on the base and fixed by screws, which will affect the strength of the base and shorten its service life
