Description

Back plate for door and window handle

Technical Field

The utility model belongs to door and window accessory specifically is a backplate is used to door and window handle.

Background

The existing fixing mode of the handle without the base is generally divided into the following two types:

(1) fix on the transmission box, this kind of mode divide into direct fixation and indirect fixation, and direct fixation has screw hole lug connection handle on the transmission box, and indirect fixation has unsteady screw hole backplate on the transmission box, and the handle is fixed on the backplate that floats, and the mounting hole is aimed at to the handle not convenient for during the assembly, and the handle often rotates moreover, leads to the junction to become invalid easily, and at this moment has to be changed the transmission box, causes the wasting of resources, has also increased the cost.

(2) Fix on the screw backplate, effective thread length when this kind of mode is connected is shorter, and along with the handle rotates the number of times and becomes many, threaded connection loses efficacy gradually, and the handle will become flexible, even if change the bolt because thread length is limited, also can't reach stable joint strength, life is short.

Disclosure of Invention

In order to solve the problem, the utility model provides a door and window is backplate for handle, easy to assemble, fixed connection intensity is high, and live time is long, the convenient change. The utility model adopts the technical scheme as follows:

a back plate for a door and window handle comprises a shell, wherein two screw hole seats and an axle seat are arranged in the shell, the axle seat is arranged in the middle of the shell, the two screw hole seats are symmetrically arranged on two sides of the axle seat, and through holes are correspondingly formed in the positions, corresponding to screw holes in the screw hole seats, of the shell and in the positions, corresponding to axle holes in the axle seat, of the axle seat; the shaft seat is used for inserting a rotating shaft of the handle, and the screw hole seat is used for being in threaded connection with a bolt on the handle base.

Above-mentioned backplate for door and window handle, be equipped with the U type groove with handle pivot location fit on the axle bed.

Above-mentioned backplate for door and window handle, the shell is two components that are the relative cooperation of C font, the shell blocks the screw hole seat for the interference.

According to the back plate for the door and window handle, bosses are arranged at the positions, provided with the screw holes, of the two sides of the screw hole seat so as to be in positioning fit with the corresponding through holes in the shell.

According to the back plate for the door and window handle, the shell is rectangular, the outer edge of the shaft seat is circular, and the matching part of the screw hole seat and the outer edge of the shaft seat is an arc surface.

The utility model has the advantages that: the back plate can be assembled quickly and conveniently, and the assembly efficiency is improved. Meanwhile, the structure of the existing transmission box is not required to be changed, the effective length of the threads on the back plate is increased, and the connection reliability and the service life of the handle are improved.

Fig. 1 is a schematic structural diagram of an embodiment of the present invention;

fig. 3 is a schematic view of a usage status of the embodiment of the present invention;

fig. 2 is a schematic sectional view of the usage state of the present invention.

In the figure: 1 is a shell, 2 is a screw hole seat, 3 is a shaft seat, 4 is a rotating shaft, 5 is a base, 6 is a rotating handle and 7 is a spring pin.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

The embodiment is a backplate for door and window handles, and the backplate wholly is the cuboid form, and it includes shell 1, two screw hole seats 2 and an axle bed 3 all establish in shell 1. The outer edge of the shaft seat 3 is arc-shaped and is positioned in the middle of the shell 1, and the two screw hole seats 2 are symmetrically arranged on two sides of the shaft seat 3 to clamp the shaft seat 3 in the middle.

Through holes are respectively and correspondingly formed in the positions, corresponding to the screw holes in the screw hole seat 2, of the shell 1 and the positions, corresponding to the shaft holes in the shaft seat 3, of the shaft seat; the shaft seat 3 is used for being inserted into a rotating shaft 4 of the handle, and the screw hole seat 2 is used for being screwed with a bolt on the handle base 5.

The shaft seat 3 of the back plate is provided with a U-shaped groove matched with the spring pin 7 on the handle rotating shaft 4 in a positioning way.

The screw holes on the two sides of the screw hole seat 2 of the back plate are provided with bosses to be matched with the corresponding through holes on the shell 1 in a positioning manner, so that the back plate is convenient to position and assemble. The shell 1 is two thin-wall metal pieces with C-shaped sections, and the screw hole seat 2 is clamped through a stamping process.

The backplate of this embodiment adopts "sandwich" structure, during the use, puts the section bar with the backplate earlier, and the bolt on the base 5 of handle passes screw hole seat 2, and axle bed 3 is inserted to pivot 4 of handle simultaneously, screws up the bolt in the U type groove of axle bed 3 just in time of spring catch 7 on the back pivot 4, stirs and rotates handle 6 then the pivot rotates, and axle bed 6 also rotates thereupon. The screw hole seat 2 is high in connection strength, convenient to use and capable of improving assembling efficiency.
