A device for fixing a steel ball slide rail bead rack

Abstract

The utility model belongs to the field of steel ball slide rails, and in particular, is a device for fixing a steel ball slide rail bead rack. In view of the existing steel ball slide rails, due to the irregular movement of the internal bead pieces, the position of the bead rack cannot be seen during installation, so that the inner strip of the slide rail often pushes the bead rack and causes the problem of frequent occurrence of inferior waste products. The following scheme is now proposed, which includes a slide rail outer strip, which is in the shape of a U-shaped long strip; a slide rail middle strip, which is in the shape of a U-shaped long strip; a steel ball slide rail bead rack, which is placed in the slide rail middle strip, and includes a bow-shaped slide rail sheet rack and steel balls rotatably connected to the two sides of the slide rail bead rack. In the utility model, an M-shaped plastic block for fixing the bead rack is added to the original M-shaped plastic part of the middle strip, so that the bead rack is fixed to the front of the middle strip. When installing the inner strip of the slide rail, the position of the inner strip of the slide rail entering the slide rail bead rack can be clearly seen, which greatly improves the installation speed and can also avoid inferior waste products caused by the damage of the slide rail strips due to blind installation.

Description

Technical Field

[0001] The utility model relates to the technical field of steel ball slide rails, in particular to a device for fixing a bead frame of a steel ball slide rail. Background Art

[0002] Slide rails are hardware connection parts fixed to the cabinet body of furniture to allow the drawers or cabinet panels of furniture to move in and out. Slide rails are suitable for connecting drawers of wooden and steel drawers in cabinets, furniture, document cabinets, bathroom cabinets and other furniture.

Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that the bead rack of the steel ball slide rail moves irregularly, which results in the position of the bead rack being invisible during installation, causing the inner strip of the slide rail to often push and damage the bead rack, resulting in frequent generation of inferior and waste products, and proposes a device for fixing the bead rack of the steel ball slide rail.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A device for fixing a steel ball slide rail bead rack, comprising a slide rail outer strip, which is in the shape of a U-shaped long strip; a slide rail middle strip, which is in the shape of a U-shaped long strip; a slide rail bead rack, which is arranged in the slide rail middle strip and comprises a bow-shaped slide rail bead rack and steel balls rotatably connected to the upper and lower sides of the slide rail strip; a slide rail inner strip; an M-shaped plastic block, which is arranged at the front end of the slide rail middle strip and comprises an installation block that is buckled in a slot opened in the slide rail middle strip and a plastic limit block integrally arranged with the installation block, and the installation block is in the shape of an M.

[0007] In a possible design, the slide rail bead rack is clamped on the front end of the middle bar of the slide rail through steel balls on both sides and connected thereto.

[0008] In a possible design, the slide rail bead rack is automatically pushed to the front end of the middle bar of the slide rail by a pneumatic push rod provided on the slide rail assembly machine.

[0009] In a possible design, the outer rail strip, the middle rail strip and the rail bead frame are all formed by bending steel plates.

[0010] In a possible design, the plastic limit block is located on a side of the mounting block close to the slide rail bead rack, and a bead rack limit block is added to the front end of the plastic limit block, and the bead rack is fixedly limited by the bead rack lock tongue.

[0011] In a possible design, an operating protrusion is provided on the top inner wall of the installation block, and side spring plates are provided on both sides of the installation block.

[0012] In one possible design, the plastic limit block is located on one side of the installation close to the middle bar of the slide rail, and a bead rack lock tongue is integrally formed on the inner wall of one side of the plastic limit block, one end of the bead rack lock tongue is inclined, and side fixing springs are provided on both sides of the top of the installation block, and a bead rack fixing device is added near the bead rack position, and the bead rack is fixed to the front part of the middle bar of the slide rail by the bead rack lock tongue, so that the bead rack position can be clearly seen during installation, avoiding the previous blind installation, improving installation efficiency, and reducing the phenomenon of small strips damaging the bead pieces due to the inability to see the bead piece position during installation.

[0013] In this application, first in the production process:

[0014] 1. The middle rail, bead rack and steel ball are automatically assembled together on the rail assembly machine through the pneumatic push rod. At the same time, the plastic limit block is automatically installed at the front end of the middle rail through the vibration plate.

[0015] 2. Assemble the outer rail of the slide rail and the middle rail of the slide rail with the bead rack and plastic limit block installed.

[0016] 3. A specially designed pneumatic device pushes the bead rack installed in the middle bar of the slide rail into the bead rack lock tongue of the plastic limit block, thereby fixing the position of the bead rack of the slide rail.

[0017] Beneficial effects:

[0018] In the utility model, the device for fixing the steel ball slide rail bead frame can clearly see the position where the slide rail inner strip enters the slide rail bead frame when installing the slide rail inner strip, which greatly improves the installation speed and can also avoid the inferior waste caused by the damage of the slide rail strip due to blind installation;

[0019] In the utility model, the plastic limit block is located at the installation block near the front end of the middle bar of the slide rail, and a supporting spring sheet is arranged inside the plastic limit block, so that when the installation block is fixed on the middle bar of the slide rail, the plastic limit block can be inserted into the gap between the slide rail bead rack and the middle bar of the slide rail, thereby further increasing the stability of the fixation of the slide rail bead rack.
