A door and window handle structure

Abstract

The invention provides a door and window handle structure, which includes a handle, a base for installing the handle, and a square core. The handle has a mounting column for mounting and fixing the base, and the axis of the mounting column has an axis hole for assembling the square core; The base includes an upper metal plate, a mounting plate and a lower metal plate which are stacked and fixed in sequence, and the base has a mounting hole for a vertically penetrating assembly mounting column; the side walls of the mounting holes of the upper metal plate and the lower metal plate are all mounting columns The outer wall of the mounting column provides radial support around the circumference; a number of elastic positioning protrusions distributed around the circumference and extending radially out of the inner wall of the mounting hole are installed on the mounting plate, and the outer peripheral wall of the mounting column has a number of positioning concaves that can match the elastic positioning protrusions; The mounting plate is also provided with a locking piece radially abutted by the elastic piece and can protrude from the inner wall of the mounting hole. The outer peripheral wall of the mounting column has a lock groove radially matched with the locking piece, and the outer wall of the base has a radially toggle locking the operation window of the software. The handle has strong structural stability, low cost and is easy to assemble and disassemble.

Description

technical field [0001] The invention relates to the technical field of door and window hardware, in particular to a door and window handle structure. Background technique [0002] The rotatable handle of the door and window is usually used in conjunction with the lock box, and the lock box can be opened or locked by the rotation of the handle. The existing handle structure usually includes a handle, a base on which the handle is mounted, and a square core that rotates synchronously with the handle to control the action of the lock box. like figure 1 As shown in an existing handle structure, the handle 11 and the square core 12 are locked and fixed by oblique screws 13, while the square core 12 is passed through a metal base 15 through a bushing 14, and then A circlip 16 is provided on the bottom side of the base 15 to limit the axial position of the core 12 , and an elastic positioning protrusion 17 is provided on the base 15 to abut against the outer peripheral wall of th...

AI Technical Summary

Problems solved by technology

In this handle structure, 1. The handle is only fixed to the square core by a screw on one side, and the stability is poor. It is necessary to provide stable radial support for the square core. Therefore, on the one hand, it is necessary to have a long fitting length between the base and the bushing, resulting in a higher overall base. On the other hand, the base needs to adopt a thicker support structure such as walls and ribs, and also need to install structures such as elastic positioning protrusions between the base and the sleeve, so the structure of the base and sleeve is complicated, and usually needs to be formed by metal casting, resulting in high cost; 3. When When the handle or lock box needs to be installed or repaired, the base must be removed first, and then the clip spring can be taken out from the bottom of the base before the handle and the base can be disassembled. The operation is complicated and difficult
