Technical Field

The invention belongs to the technical field of machinery, and relates to a composite slide rail.

Background

The slide rail is used for installing between the cabinet body and the drawer, enables the smooth and stable removal of drawer for the cabinet body under the effect of slide rail.

The existing sliding rail generally comprises two parts, namely a first body fixedly connected to the cabinet body and a second body fixedly connected to the drawer, wherein the second body is embedded in the first body, and the first body and the second body have a guiding effect, so that the drawer can stably and smoothly move relative to the cabinet body.

However, in the existing slide rail, the first body and the second body are directly based, and the friction resistance is large, the abrasion is also large, and the stability is poor.

Disclosure of Invention

The present invention is directed to solve the above problems in the prior art, and an object of the present invention is to provide a composite slide rail with high stability and compact structure.

The purpose of the invention can be realized by the following technical scheme:

the utility model provides a combined type slide rail, its characterized in that, is including being rectangular form body one and body two, and above-mentioned body one side portion has concave guide way and has convex fender edge in guide way port department, and above-mentioned body two inlays in guide way department with guide way phase-match and body two, two lateral parts of body still have and are used for linking firmly at connecting portion and connecting portion stretch out the guide way with the drawer, and above-mentioned body two and keep off and have the contact structure that can reduce both frictional resistance between the edge.

The contact structure is creatively arranged between the first body and the second body, the friction resistance between the first body and the second body is reduced under the action of the contact structure, and finally the second body can smoothly move relative to the first body.

The first body is used for being fixedly connected to the cabinet body, the second body is used for being fixedly connected to the drawer, the drawer can be stably connected to the cabinet body finally through the combined type sliding rail, and the drawer can be stably and smoothly translated relative to the cabinet body.

In the composite slide rail, the two ends of the first body are respectively provided with a convex shoulder, and the second body can abut against the convex shoulders after moving along the guide groove of the first body.

Because both ends of the first body are provided with the convex shoulders, the second body cannot move continuously after being abutted against the convex shoulders, and finally the second body is ensured to move within a set stroke range.

In foretell combined type slide rail, the contact structure includes the connecting hole that runs through on the body two, have ball one, ball two and spring in the connecting hole, above-mentioned spring is located between ball one and the ball two and ball one has the trend that supports and lean on keeping off along under the spring action of spring, and ball two has the trend that supports and lean on in guide way bottom department.

Under the action of the elastic force of the spring, the first ball and the second ball respectively extend out of two sides of the second body, the first ball abuts against the blocking edge, and the second ball abuts against the bottom of the guide groove.

In the composite slide rail, the two ends of the body are fixedly connected with flexible buffer blocks.

The second body can be prevented from being in rigid contact with the second body under the action of the buffer block.

In the above-mentioned composite slide rail, the buffer block is square and made of rubber material.

In the composite slide rail, the two end parts of the body are provided with concave positioning seats, the buffer block is embedded in the positioning seats, and the buffer block is tightly matched and connected with the two end parts of the body.

The structure enables the buffer block to be stably connected to the second body.

In the composite slide rail, the connecting hole, the first ball, the second ball, the spring and the blocking edge form a contact unit, the number of the contact units is two, and the two contact units are symmetrically distributed on two sides of the body.

The arrangement of the two contact units can further improve the connection stability of the second body and the first body.

In the above-mentioned composite slide rail, the blocking edge and the body are of an integral structure.

In the above-mentioned composite slide rail, the connecting portion is block-shaped, and the connecting portion is located between two adjacent retaining edges.

The connecting part is stably connected with the second body, and certainly, the second body is provided with enough positions for being fixedly connected with the side parts of the drawer.

Compared with the prior art, the composite slide rail has the advantages that the second body is stably limited in the first body, so that the second body can stably move within a set stroke range, and the stability is high.

Meanwhile, the contact structure is positioned between the first body and the second body, so that the contact structure does not occupy too much space, is more compact in structure and has high practical value.
