Four-section type window handle structure convenient to replace parts

Abstract

The invention discloses a four-section type window handle structure convenient to replace parts. The four-section type window handle structure comprises a handle and a handle installation seat; the handle is provided with a drive shaft; a strip-type groove is formed in the drive shaft; the handle installation seat is composed of a base, fixed parts, limiting blocks and a sliding block; an active groove are formed in the middle portion of the base, pipe parts are symmetrically arranged at both sides of the base, limiting grooves are formed in the peripheries of the pipe parts; the sliding blockcomprises a sliding ring body, the inner wall of the sliding ring body is provided with the baffle block, and grooves are formed in the outer wall of the sliding ring; the limiting blocks comprise limiting ring bodies; and the outer walls of the limiting ring bodies are provided with limiting plate parts, spanner parts, and the middle portions of the outer sides of the limiting plate parts are provided with raised lines. Two limiting blocks and a sliding block are used for driving the handle to open, close or tilt the window; the three parts involved in friction are low in production cost, and can be replaced locally when the wear is serious to reduce the replacement cost; and, besides, the grooves can be rolled and contacted by rotating the raised lines, and friction can be reduced and the movement more flexible and light.

Description

technical field [0001] The invention relates to the technical field of door and window accessories, in particular to a four-section window handle structure that facilitates parts replacement. Background technique [0002] The kind of existing door and window lockset is a lot, and in order to make things convenient for people to open or close doors and windows, usually door and window handles can be installed on the door and window lockset. Common door and window handles generally include a handle, a handle mount and a drive shaft. The handle is rotatably mounted on the handle mount, and the drive shaft is fixed on the handle. The movement of the transmission mechanism in the lockset controls the movement of the dead bolt or the lock pin in the lockset to lock or open the doors and windows. [0003] In order to avoid turning the handle excessively, there are such as attached Figure 7 The positioning type window handle structure shown is a four-stage positioning mode in whic...

AI Technical Summary

Problems solved by technology

There are deficiencies in the use of this window handle structure. One is that the steel balls slide and rub under the extrusion of the spring, which is relatively large and prone to noise; One-piece structure, when the wear is serious, it can only be replaced as a whole, and the replacement cost is high
