Abstract

The utility model discloses a linear slide rail with dustproof sheets. The linear slide rail with dustproof sheets comprises a rail bar of a long strip-shaped structure, a slide module, two dustproof sheets and a plurality of screws, wherein the slide module is nested on the rail bar and reciprocates relative to the rail bar, and the direction that the slide module reciprocates is defined as the axis direction, and locking holes are arranged on two end surfaces of the axis direction of the slide module; the two dustproof sheets are arranged on two end surfaces of the slide module respectively, perforations opposite to the locking holes are arranged on the two dustproof sheets, an isolation groove surrounding the perforation is arranged with an interval with the perforation, and each of the dustproof sheets is provided with a lip part attached to the surface of the rail bar; the plurality of screws penetrate through the perforation and then are screwed and locked with the locking holes to fix the dustproof sheet on the end surface of the slide module. With the structure, the deformation of the lip part of the linear slide rail with dustproof sheets caused by the locking force of the screws may be avoided.

Description

The linear slide rail with dustproof sheet

Technical field

The utility model relates to a kind of accessory of linear slide rail, refers in particular to a kind of dustproof sheet of linear slide rail, can prevent dustproof sheet and because of locking, produce distortion.

Background technique

Linear slide rail is conventionally by the rail bar of galleyproof type, slide block module and a plurality of roll piece form, and slide block module is sheathed on this rail bar, a plurality of these roll pieces are arranged between this slide block module and rail bar, as this slide block module and rail bar driving medium between the two, in order to prevent foreign matter from invading slide block module, draw and ring roll piece operation, therefore can install dustproof sheet additional in this slide block module, this dustproof sheet is provided with a lip, the surface laminating of this lip and this rail bar, in order to seal this slide block module, make its inside and external isolation avoid foreign body intrusion inner, and this dustproof sheet is fixed in slide block module with screwed lock conventionally, but the locking power of this screw of this dustproof sheet Chang Yinwei is excessive, and cause this dustproof sheet distortion and then affect this lip and the adaptation of rail bar laminating, and reduced the effect that seals this slide block module, relatively also improved the possibility of the inside of foreign body intrusion slide block module, necessity that historical facts or anecdotes has improvement to progress greatly.

In view of this, the design people is for not attaining perfect caused many disappearances and inconvenience in the design of above-mentioned linear slide rail dustproof construction, and deeply design, and active research improvement has a fling at and development and Design goes out this case.

Model utility content

The purpose of this utility model is to provide a kind of linear slide rail with dustproof sheet, and it can avoid the locking power because of screw, and causes the lip distortion of dustproof sheet.

In order to reach above-mentioned purpose, solution of the present utility model is:

A linear slide rail with dustproof sheet, it comprises: a rail bar, it is strip structure; One slide block module, is sheathed on this rail bar, and this rail bar back and forth moves relatively, and the direction that defines the reciprocal operation of this slide block module is axle direction, and the axial both ends of the surface of this slide block module are respectively equipped with locking hole; Two dustproof sheets, it is arranged at respectively the both ends of the surface of this slide block module, and two these dustproof sheets are provided with the perforation of this locking hole relatively, are provided with an isolation channel around this perforation with this perforation interval one spacing, and this dustproof sheet is provided with the surperficial lip that is attached at this rail bar; A plurality of screws, are arranged in this perforation afterwards and this locking hole screws togather locking, this dustproof sheet is fixed on to the end face of this slide block module.

Adopt after said structure, the utility model is when this screw imposes a locking force to this dustproof sheet, conventionally this locking force can make surrounding's generation distortion of this perforation, but can avoid this distortion to be outwards passed to lip by the design of this isolation channel, therefore can avoid this lip to produce distortion, make the surface laminating of this lip and this rail bar, to avoid the improving tightness that dustproof sheet seals this slide block module, and improved the problem of prior art.

Embodiment

In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.

Refer to shown in Fig. 1 to Fig. 2, the utility model is a kind of linear slide rail with dustproof sheet, comprises: a rail bar 1, and it is strip structure; One slide block module 2, is sheathed on this rail bar 1, and this rail bar 1 back and forth moves relatively, and the direction that defines these slide block module 2 reciprocal operations is axle direction X, and the both ends of the surface of the axle direction X of this slide block module 2 are respectively equipped with locking hole 21; Two dustproof sheets 3, it is arranged at respectively the both ends of the surface of this slide block module 2, two these dustproof sheets 3 are provided with the perforation 31 of this locking hole 21 relatively, are provided with an isolation channel 33 around this perforation 31 with these 31 interval one spacing of boring a hole, and this dustproof sheet 3 is provided with the surperficial lip 32 that is attached at this rail bar 1; A plurality of screws 4, are arranged in this perforation 31 afterwards and this locking hole 21 screws togather locking, this dustproof sheet 3 is fixed on to the end face of this slide block module 2.

The configuration of each element is more than described, the utility model mode of execution is below described:

Refer to shown in Fig. 3 to Fig. 4 B, for dustproof sheet 3 is assembled to the combination section of slide block module 2, Fig. 3, Fig. 3 A, Fig. 3 B is the state that screw 4 is not yet locked, and assembler is while further locking this screw 4, can make the surrounding of the perforation 31 of this dustproof sheet 3 be subject to the locking force F of screw 4 and be out of shape, as Fig. 4, Fig. 4 A, shown in Fig. 4 B, for fear of this distortion is passed to lip 32, the utility model is by the setting of this isolation channel 33, block this distortion and be passed to lip 32, to avoid this lip 32, cannot fit with the surface of this rail bar 1, improve the tightness of dustproof sheet 3 these slide block modules 2 of sealing.

Above-described embodiment and accompanying drawing non-limiting product form of the present utility model and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present utility model.
