Abstract

The utility model relates to a rolling guide, including guide rail, slider and three group's rollers, the roller is located between guide rail and the slider, and first group's roller and second group's roller are located relative both sides, and the roller includes that a plurality of balls and ball keep ware, is equipped with the roller passageway in the slider, and the roller passageway includes inside passage, outside passageway and interface channel, and inside passage and outside passageway are sharp passageway, and the interface channel is the arc passageway, and interface channel is passed through at inside passage and outside passageway's both ends and is connected, and outside passageway is equipped with the opening. The utility model has the advantages that: the rolling guide rail adopts three groups of rollers, wherein two groups of rollers are opposite, the other group of rollers are positioned on the other side, the sliding blocks and the guide rail are stably contacted without other rollers, so that the number of the rollers of the rolling guide rail is reduced, and the production cost is reduced.

Description

Rolling guide rail

Technical Field

The utility model relates to a guide rail especially relates to a rolling guide.

Background

The guide rail is a common mechanism that can limit the movement of the slider along the guide rail. The prior art guide rails are typically rolling guide rails. The rolling guide rail is internally provided with a ball, so that the abrasion of the sliding block and the guide rail is reduced. However, the rolling guide rail in the prior art is lack of a sufficient and effective mode for the ball arrangement mode, and the working efficiency of the balls is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide a rolling guide, make the ball more high-efficient.

The utility model discloses a realize through following technical scheme:

the utility model provides a rolling guide, includes guide rail, slider and three roller of group, the roller is located between guide rail and the slider, first roller of group and the second roller of group are located relative both sides, the roller includes that a plurality of balls and ball keep ware, be equipped with the roller passageway in the slider, the roller passageway includes inside passageway, outside passageway and interface channel, inside passageway and outside passageway are sharp passageway, interface channel is the arc passageway, the both ends of inside passageway and outside passageway are passed through interface channel and are connected, outside passageway is equipped with the opening.

According to the above technical solution, preferably, the ball retainer is composed of a plurality of retainers, the retainers include a ring for fixing the balls and hooks on both sides of the ring, and the retainers are connected by the hooks.

The utility model has the advantages that: the rolling guide rail adopts three groups of rollers, wherein two groups of rollers are opposite, the other group of rollers are positioned on the other side, the sliding blocks and the guide rail are stably contacted without other rollers, so that the number of the rollers of the rolling guide rail is reduced, and the production cost is reduced.

Drawings

Fig. 1 shows a schematic cross-sectional structure of an embodiment of the present invention.

Fig. 2 shows a schematic longitudinal sectional structure diagram of an embodiment of the present invention.

In the figure: 1. guide rail, 2 slide block, 3 balls, 4 ball retainer, 5 internal channel, 6 external channel, 7 connecting channel.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figure, the utility model relates to a rolling guide, including guide rail 1, slider 2 and three group's rollers, the roller is located between guide rail and the slider, first group roller and second group roller are located relative both sides, the roller includes that a plurality of balls 3 and ball keep ware 4, be equipped with the roller passageway in the slider, the roller passageway includes inside passage 5, outside passage 6 and interface channel 7, inside passage and outside passage are sharp passageway, interface channel is the arc passageway, interface channel connects is passed through at inside passage and outside passage's both ends, outside passage is equipped with the opening.

Example (b):

generally, the guide rail has a pair of opposing faces and another face, the other face being non-parallel to the opposing faces. The slide block can be contacted with the opposite surface of the guide rail through two groups of rollers, and the other group of rollers is contacted with the other surface of the guide rail. Through the connection mode, the slide block and the guide rail are kept in firm contact, and the number of the rollers is minimized.

According to the above embodiment, preferably, the ball retainer is composed of a plurality of retainers including a ring for fixing the balls and hooks on both sides of the ring, and the retainers are connected by the hooks. The retainer prevents collision between the balls and reduces noise.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.

Claims
