Description

A kind of fixture for the desk and chair leg

Technical field

A kind of fixture for the desk and chair leg of the utility model belongs to field of furniture, particularly relates to a kind of for the desk and chair leg, easy for installation and play the fixture of fixation.

Background technology

Desk and the chair of now school's use have comparatively fixing regulation, but still are single whippletree fixed form of main flow in the design of the chair leg of desk and chair.This kind form is take a hollow iron pipe as connecting the carrier of both sides chair leg, uses 2 fixedly distances between the both sides chair leg.But because the chair leg contact-making surface on iron and both sides is a circular weld position, therefore deformation easily occurs in its this kind desk and chair leg when permanent use or chance external force, so that chair leg skew, four chair pin not at grade, the situation that causes chair to only have three pin to land.In a single day this kind situation occurs, and then this desk and chair need to be repaired, inconvenient routine use.

The utility model content

The purpose of this utility model is to avoid the weak point of existing equipment technology, and provides a kind of easy for installation, can repeatedly use, and desk and chair leg fixture that can be in order to be effective.

The purpose of this utility model reaches by following measures, fixture for the desk and chair leg of the present utility model comprises parallel bars fixed bar, brace, latch, screw hole, welding latch at the desk and chair leg near the place of bottom, parallel bars fixed bar both sides are provided with the brace with the latch equidimension, and the latch lower position is provided with screw hole.

Two bars of parallel bars fixed bar of the present utility model design for parallel construction.

Latch of the present utility model designs for inverted U, and namely latch can make brace be fixed on a position from three bread round brace, namely so that the parallel bars fixed bar is fixed on a position.

The utility model is simple in structure, and is easy to use, and safety is guaranteed.

Description of drawings

Accompanying drawing 1 is enforcement structural representation of the present utility model.

Accompanying drawing 2 is structural representations of the present utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Among the figure: parallel bars fixed bar 1, brace 2, latch 3, screw hole 4.

As shown in Figure 1, seat cushion of the present utility model comprises parallel bars fixed bar 1, brace 2, latch 3, screw hole 4, welding latch at the desk and chair leg near the place of bottom, parallel bars fixed bar both sides are provided with the brace with the latch equidimension, and the latch lower position is provided with screw hole.

During use, the brace at parallel bars fixed bar two ends is boosted along latch, so that the brace top flushes with the latch top, and then the screw hole position of pasting the brace bottom screw of screwing on, so that the parallel bars fixed bar is fixed on the two chair legs.Because the contact-making surface of parallel bars fixed bar and two chair legs has formed a fixed structure of 4 one sides, so that two chair leg positions are relatively fixing, the situation that one of them pin upwarps can not occur.

Claims

1. fixture that is used for the desk and chair leg, comprise parallel bars fixed bar, brace, latch, screw hole, welding latch at the desk and chair leg near the place of bottom, parallel bars fixed bar both sides are provided with the brace with the latch equidimension, and the latch lower position is provided with screw hole.

2. the fixture of desk and chair leg according to claim 1 is characterized in that two bars of parallel bars fixed bar design for parallel construction.
