Description

Telescopic cover for improved shielding

The present invention relates to a mechanical accessory, and more particularly to a telescopic cover that can enhance the shielding effect.

In general mechanical or machine tools, in order to prevent the transmission components from being contaminated by chips, cutting fluid, dust, etc., a telescopic cover is often installed between the moving member and the fixed member. In addition, the general gantry machining center machine also installs a telescopic cover in order to prevent oil and gas from spreading to the processing site.

The telescopic cover comprises a pair of rails, a plurality of pairs of sliding units respectively slidable along the rails, and a shielding unit connected to the sliding units and extendable or retractable.

A conventional sliding unit mounted on a telescopic cover, such as the TW certificate number M482342 patent, is provided with a track shaft portion on a base of a track, and a plurality of fixing members connected to a shielding unit are slidably sleeved on the tracks. Shaft section. Although the telescopic cover can be slid along the shaft portions of the rails by the sliding grooves of the fixing members during stretching or folding, and the shielding unit can be extended or condensed, because the side ends of the shielding unit are It is so open that the resulting shading effect is still poor.

Therefore, the object of the present invention is to provide a telescopic cover which has a simple structure and can improve the shielding effect.

Therefore, the novel telescopic cover capable of improving the shielding effect comprises a pair of guide rails, a plurality of sliding units and a shielding unit. The rails respectively extend along a first axial direction and each have an inner side surface, an outer side surface opposite to the inner side surface, and a top surface that is coupled between the inner side top edge and the outer side top edge. The sliding units each have a pair of locating members slidably disposed on the top surfaces, and a supporting member coupled between the positioning members, at least one pair being respectively connected to the positioning members and opposite to the inner portions a side inner guide wheel, at least one pair of outer guide wheels respectively connected to the positioning members and opposite to the outer side surfaces, the shielding unit is disposed between the rails and connected to the sliding unit, along the first Axially extending or condensing, and having a main shielding member connected to the supporting members and a plurality of side covering members connected to the main shielding member, the main shielding member and the side shielding members are made of a flexible material. The side shields respectively correspond to the inner guide wheels and each have an end that approaches the inner side of the rails.

The effect of the present invention is that the side shields of the shielding unit are connected to the main shielding member, and the side shielding members respectively correspond to the inner guiding wheels, and when the sliding units drive the shielding unit to expand or condense, The use of the side shields produces better shielding.

Other features and effects of the present invention will be clearly shown in the embodiments with reference to the drawings, wherein: FIG. 1 is a three-dimensional combination diagram illustrating the extension of the present invention to enhance the shielding effect. FIG. 2 is a partial perspective view of a portion of the above-described embodiment of the present invention; FIG. 3 is a top plan view of the above-described embodiment of the present invention; and FIG. 4 is a line IV-IV along the line of FIG. A section view.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to FIG. 1 and FIG. 2, an embodiment of the telescopic cover capable of improving the shielding effect comprises a pair of guide rails 10, a plurality of sliding units 20 and a shielding unit 30.

The guide rails 10 are long rod-shaped, respectively extending along a first axial direction X, and the second axial direction Y perpendicular to the first axial direction X has a rectangular cross section, and each has an inner side surface 11 and a opposite The outer side surface 12 of the inner side surface 11 and a top surface 13 that is coupled between the top edge of the inner side surface 11 and the top edge of the outer side surface 12.

Each of the sliding units 20 has a pair of locating members 21 slidably disposed across the top surfaces 13 and a pair of top wheels 22 respectively disposed on the positioning members 21, at least one pair of shafts respectively disposed thereon And the inner guide wheel 23 of the inner side surface 11 and the at least one pair of outer guide wheels 24 respectively disposed on the outer side surface 12 and opposite to the outer side wheel 12, along the second axis A support member 25 extending to Y and connected between the two opposite positioning members 21 and a plurality of buffer members 26 respectively mounted to the support members 25 are respectively connected.

In this embodiment, the number of the inner guide wheels 23 on each of the positioning members 21 is one pair, and the number of the outer guide wheels 24 is one, but the outer guide wheels 24 may also be used. The number is set to one pair, and the number of inner guide wheels 23 is set to one (not shown).

The cushioning members 26 each have a fixing base 261 fixed to the supporting members 25 and a cushioning pad 262 which is mounted on the end of the fixing base 261 in the first axial direction and is made of rubber material.

The shielding unit 30 is disposed between the rails 10 and has a main shielding member 31 connected between the supporting members 25 and a plurality of side shielding members 32 connected to the main shielding member 31. The main shielding member 31 is provided. The side cover members 32 are respectively corresponding to the inner guide wheels 23 and have a brush shape, and each has an end 321 which is close to the inner side surface 11 of the guide rails 10. When the support members 25 of the sliding units 20 are separated or abutted along the first axial direction X, the main shielding members 31 can be extended or condensed along the first axial direction X.

As shown in FIG. 1 , FIG. 3 and FIG. 4 , the shielding unit 30 is in an extended state, and the supporting members 25 of the sliding units 20 are separated from each other along the first axial direction X. The main shielding of the shielding unit 30 When the piece 31 extends along the first axial direction X, it can shield the machine or the machine tool (not shown), and the ends 321 of the side cover members 32 respectively correspond to the inner guide wheels 23 and approach. The inner side surface 11 of the guide rails 10 can also have a small gap between the shielding unit 30 and the inner side surface 11 of the guide rails 10, so that the shielding effect is good.

When the cover is to be opened when the machine or the machine tool is to be placed or replaced, the sliding unit 20 can be operated to move along the guide rails 10, and the main shielding member 31 of the shielding unit 30 is interlocked by the sliding units 20. Will be in a condensed state by the extended state operation, and the support members 25 In this case, at this time, the cushioning member 26 attached to the supporting member 25 can abut against the adjacent one of the supporting members 25, that is, the cushioning pad 262 of the cushioning member 26 abuts against the adjacent one of the supporting members. 25, can produce a buffer to avoid impact.

Therefore, by the cooperation of the main shielding member 31 and the side shielding members 32, the gap between the shielding unit 30 and the guide rails 10 can be made small regardless of whether the shielding unit 30 is in an extended state or a condensed state. Improve better shielding. Moreover, the novel structure of the novel is simple, the manufacturing assembly is easy, and the shortcomings of the prior art can be solved, and the object of the present invention can be achieved.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
