Description

Linear slide with dustproof sheet

This creation is a kind of accessories for linear slides, especially a dustproof sheet for linear slides, which can prevent the dust-proof sheets from being deformed due to locking.

The linear slide rail is generally composed of a long strip, a slider module and a plurality of rolling members, and the slider module is sleeved on the rail, and the plurality of rolling members are disposed on the slider module and the rail Between the strips, as the transmission medium between the slider module and the rail, in order to prevent the foreign matter from invading the slider module and causing the rolling member to operate, the dustproof sheet is added to the slider module. The dustproof sheet is provided with a lip that is attached to the surface of the rail to seal the slider module to isolate the inside from the outside to prevent foreign matter from invading the inside, and the dustproof piece is usually screwed to the The slider module, but the dustproof sheet is often too large, and the dustproof sheet is deformed to cause the lip to fit the rail, thereby reducing the sealing of the slider module. The effect also increases the possibility that the foreign matter invades the inside of the slider module, so it is necessary to improve the improvement.

In view of the above problems, the main purpose of the present invention is to develop a dustproof sheet locking structure capable of avoiding deformation of the lip of the dustproof sheet due to the locking force of the screw.

In order to achieve the above purpose, the present invention is a linear slide with a dustproof sheet, comprising: a rail, which is a long strip structure; a slider module is sleeved on the rail and can be opposite The rail is reciprocating, and the direction of the reciprocating operation of the slider module is defined as an axial direction, and both end faces of the slider module are respectively provided with locking holes; two dustproof sheets are respectively disposed on the sliding block mold The two end faces of the group are provided with perforations opposite to the locking holes, and an isolation groove surrounding the perforations is disposed at a distance from the perforations, and the dustproof sheet is disposed on the surface of the rail. a plurality of screws are screwed into the locking hole and locked to the locking hole to fix the dustproof piece to the end surface of the slider module.

Therefore, when the screw is applied with a locking force to the dustproof piece, the locking force usually causes deformation around the perforation, but the isolation groove is designed to prevent the deformation from being transmitted to the lip. Therefore, deformation of the lip can be avoided, and the problem of the prior art is improved.

The first figure is a system diagram for creating a linear slide with a dustproof sheet.

The second picture is a combination of the linear slides with dust-proof sheets.

The third figure is an enlarged view of the isolation groove of the dustproof sheet for creating a linear slide with a dustproof sheet, which shows the state in which the screw is not locked.

The fourth figure is an enlarged view of the isolation groove of the dustproof sheet for creating a linear slide rail with a dustproof sheet. The figure shows the state of the screw locking, and the locking groove is prevented from being transmitted outward by the arrangement of the isolation groove.

Referring to the first to second figures, the present invention is a linear slide with a dustproof sheet, comprising: a rail (1) which is a long strip structure; a slider module (2) , the sleeve is set on the rail (1), and can reciprocate relative to the rail (1), and the direction of the reciprocating operation of the slider module (2) is defined as an axial direction (X), the slider module ( 2) Both ends of the axial direction (X) are respectively provided with locking holes (21); two dustproof sheets (3) are respectively disposed on the two end faces of the slider module (2), and the two dustproof sheets ( 3) a through hole (31) opposite to the locking hole (21), and a spacing groove (33) surrounding the through hole (31) is provided at a distance from the hole (31), and the dustproof piece (3) is provided a lip portion (32) attached to the surface of the rail (1); a plurality of screws (4) are threaded and locked with the locking hole (21) after being inserted through the through hole (31) to The dustproof piece (3) is fixed to an end surface of the slider module (2).

The above describes the configuration of each component. The following describes the implementation of this creation:

Please refer to the third to fourth figures, which are the combined sectional view of the dustproof piece (3) assembled to the slider module (2), and the third figure is the state in which the screw (4) is not locked yet, and assembled. When the person further tightens the screw (4), the periphery of the perforation (31) of the dustproof piece (3) is deformed by the locking force (F) of the screw (4), as shown in the fourth figure, in order to avoid The deformation is transmitted to the lip (32), and the creation is blocked by the arrangement of the isolation groove (33) to prevent the deformation from being transmitted to the lip (32) to prevent the lip (32) from being attached to the rail ( 1) The surface is attached to improve the sealing degree of the dustproof piece (3) sealing the slider module (2).

In view of the above, the "industry availability" of this creation should be unquestionable. In addition, the characteristic techniques revealed in the examples in this case have not been seen in publications before, and have not been disclosed. The use, not only has the fact that the effect is improved as described above, but also has additional functions that cannot be neglected. Therefore, the "novelty" and "progressiveness" of the creation have been in compliance with the patent regulations, and the application for creating a patent is proposed according to law. Please give us a review and grant a patent as soon as possible.

The above description of the embodiments is intended to illustrate the present invention and is not intended to limit the present invention. Therefore, variations of numerical values and substitution of equivalent elements are still within the scope of the present invention.
