Problems solved by technology
[0003] This kind of sliding guide rail can only support and slide objects with a small mass. When the load of the guide rail is large, the friction between the guide rail bushing and the base is relatively large, and it is difficult to realize the sliding between the guide rail and the base. When the load on the guide rail is large, the balls in the guide rail bushing fit on the base, the contact surface between the ball and the base is small, and the contact surface between the base and the ball is prone to deformation and damage.

Embodiment Construction
[0021] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0022] Such as figure 1 and 3 As shown, a new type of linear sliding guide rail 1 includes a guide rail 1 and a support seat 2 slidingly sleeved on the guide rail 1. The guide rail 1 is fixedly arranged on the mounting plate 4 through the connecting plate 3, and the inside of the support seat 2 A cavity 5 for accommodating the guide rail 1 is opened, and an annular bush 6 is fixedly arranged in the cavity 5 .
[0023] The side wall of one side of the cavity 5 is provided with an air hole 7 connected to the outside world, and the outer surface of the bush 6 is provided with an arc-shaped groove 8 along the circumference of the bush 6, and the air hole 7 is connected to the outside. The arc-shaped grooves 8 are located on ...

The invention provides a novel linear sliding guide rail. The novel linear sliding guide rail solves the problems that when a load on an existing sliding guide rail is too large, a ball in a guide rail bush is attached to a base, the contact face between the ball and the base is too small, and the contact face between the base and the ball is likely to deform to be damaged. According to the novellinear sliding guide rail, an air cushion is formed between the bush and the guide rail through an air pump, friction between a supporting base and the guide rail is greatly reduced, and abrasion to the supporting base is reduced. The supporting base is supported doubly through a ball channel arranged between the supporting base and the rail, and friction force between the supporting base and theguide rail is further reduced. The novel linear sliding guide rail can be suitable for workpieces with different loads by changing the power of the air pump, and use is convenient.
Description
technical field [0001] The invention belongs to the technical field of sliding guide rails, in particular to a novel linear sliding guide rail. Background technique [0002] Sliding guide rails are widely used in daily life. The existing sliding guide rails usually have a guide rail bushing in the guide rail, which is in contact with the base through the guide rail bushing, and is fixed by installing balls in the guide rail bushing or using low friction materials The way to make the guide rail bushing is to reduce the friction between the guide rail and the base. [0003] This kind of sliding guide rail can only support and slide objects with a small mass. When the load of the guide rail is large, the friction between the guide rail bushing and the base is relatively large, and it is difficult to realize the sliding between the guide rail and the base. When the load on the guide rail is large, the balls in the guide rail bushing fit on the base, the contact surface between ...
