Description

Sliding retractable cover

The present invention relates to a mechanical accessory, and more particularly to a telescopic cover that can slide smoothly.

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 sliding unit that is mounted on a telescopic cover, such as the TW certificate No. M447280 patent, has a sliding wheel pivotally connected to each other on both sides of a body, and the sliding wheels can be respectively sleeved in the receiving space of a sliding rail. Although the telescopic cover can be slid along the slide rails when the telescopic cover is extended or folded, when the guide rails are flexed and deformed, the slide wheels can easily interfere with the guide rails. Even the card is stuck, which affects the smooth operation of the telescopic cover.

Another track device (TW certificate number M482342 patent For example, a rail shaft portion is disposed on a base portion, and a plurality of fixing members connected to a shielding unit are slidably sleeved on the rail shaft portions. This type of track device still has the above problems.

Therefore, the object of the present invention is to provide a smoothly slidable telescopic cover which is simple in structure and can improve the smoothness of operation.

Therefore, the present invention can smoothly slide the telescopic cover, and includes 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 across the top surfaces, at least one pair of inner guiding wheels respectively coupled to the positioning members and connected to the inner side surfaces, at least one pair connected thereto a locating member and a pair of outer guide wheels relative to the outer sides, a pair of sliding members that are slidable along the second axial direction perpendicular to the first axial direction, and a pair of sliding members coupled to the sliding member An elastic member between the positioning members, one of the inner guide wheel and the outer guide wheel of each sliding unit is coupled to the sliding member, and is movable relative to the positioning member, and the elastic force of the elastic member is constant for the inner guide a tendency of the wheel and the outer guide wheel to abut against the corresponding inner side surface and the outer side surface, the shielding unit is disposed between the sliding rails and connected to the sliding unit, and is extendable along the first axial direction or condensation.

The effect of the present invention is that the elastic members are connected between the sliding members and the positioning members, and one of the inner guiding wheels and one of the outer guiding wheels is connected to the sliding members, even if Equal deflection of the guide rail The sliding units can still slide smoothly along the guide rails, and the shielding unit can smoothly expand or condense.

With reference to FIG. 3 and FIG. 4 , the sliding units 20 each have a pair of positioning members 21 slidably disposed across the top surfaces 13 , at least one pair being coupled to the positioning members 21 and opposite to the inner side surfaces 11 . Inner guide wheel 22, at least a pair of outer guide wheels 23 connected to the positioning member 21 and opposite to the outer side surfaces 12, and a pair of sliding members 24 which are slidable along the second axial direction Y in the positioning members 21, and a pair of the sliders 24 are connected thereto. The elastic member 25 between the sliding member 24 and the positioning member 21, a support rod 26 extending along the second axial direction Y and respectively connected between the two opposite positioning members 21, and a plurality of the support rods 26 are respectively mounted on the same The cushioning member 27 of the support rod 26.

The positioning members 21 extend in a plate shape along the second axial direction Y, and Each of the openings 211, a top wheel 212 disposed in the opening 211, a fixing plate 213 fixed to one side of the opening 211, and a pair of fixing plates 213 are located on the side of the opening 211. The through holes 214 and the second holes 215 corresponding to the sliding members 24 and extending along the second axial direction Y, the top wheels 212 abut against the top surfaces 13 .

The number of inner guide wheels 22 in this embodiment is a pair, and the outer guide wheel 23 The number is two pairs, but the number of outer guide wheels 23 can also be set to one pair, and the number of inner guide wheels 22 can be set to two pairs (not shown). The inner guide wheels 22 respectively correspond to the fixing plates 213 and abut against the corresponding inner side faces 11 and each have an inner wheel shaft 221 axially disposed on the holes 214, and the inner wheel shafts 221 are opposite to the inner wheel shafts 221 The positioning members 21 produce a positioning.

The outer guide wheels 23 abut against the corresponding outer side 12, and each The outer wheel shaft 231 is connected to the sliding member 24, and the outer wheel shaft 231 of the outer conductive wheel 23 is movably disposed in the second axial direction Y and is movable relative to the positioning member 21 mobile.
