Description

[Technical Field]

[0001] The improved slider structure of the telescopic cover of the present invention is mainly applied to the sealing and protection technology of the telescopic cover, so as to reduce the entry of processing iron chips and improve the performance stability of the telescopic cover. [Previous Technology]

[0002] The applicant hereby applies for and obtains approval for the utility model patent application "Slider Structure of Telescopic Cover" under certificate number M426460. Please refer to the first figure, which is a three-dimensional combination schematic diagram of the first type. The main feature is that the telescopic cover is composed of a plurality of cover plate bodies 50 stacked and rearranged from small to large. The plurality of cover plate bodies 50 are neatly arranged above the base 80 of the processing machinery (including integrated cutting machine or grinding machine, etc.). Two guide rails 81 (including linear slide rails or hard rails) are provided on the left and right sides of the base 80. Two horizontally arranged side plates 51 are integrally formed by bending inward on the left and right sides below the cover plate body 50. A base plate 52 is provided between the two side plates 51. Two sliders 90 are inserted on the left and right sides of the base plate 52 corresponding to the two guide rails 81, so that when the telescopic cover moves, the two sliders 90 can be driven to abut against the two guide rails 81.

[0003] However, regarding the above-mentioned "slider structure of telescopic cover" new patent application, please refer to Figure 2 for actual operation and application: it is a cross-sectional combination schematic diagram of the first conventional use. Currently, the two sliders 90 are only beneficial for sliding on the surface of the two guide rails 81 and removing iron filings, but the sealing degree of the two sliders 90 is not perfect. Iron filings generated during the processing can easily enter from the edge gaps, causing damage to the internal parts. This is an existing problem and deficiency that needs to be overcome and resolved.

[0004] To improve the poor sealing effect of the aforementioned "slider structure of telescopic cover" novel patent, the current method uses a locking mechanism combined with Teflon or copper sheet as the bearing interface. Please refer to Figure 3: a three-dimensional exploded view of the second type. The main difference is that the telescopic cover is formed by stacking and rearranging a plurality of cover plate bodies 50 from small to large. These plurality of cover plate bodies 50 are neatly arranged above the base 80 of the processing machinery (including integrated cutting machines or grinding machines, etc.). Two guide rails 81 (including linear slide rails or rigid rails) are provided on the left and right sides of the base 80. Two horizontally arranged side plates 51 are integrally formed by bending inwards on the left and right sides below the cover plate body 50. Two L-shaped side plates 51 are welded to the lower inner side of the two side plates 51. The positioning pieces 60 extend inwardly and have two locking surfaces 61. The two locking surfaces 61 have a plurality of screw holes 62, which can be used by a plurality of screws P to lock together. Two Teflon or copper sheets 70 are provided. The two Teflon or copper sheets 70 have a plurality of fish-eye holes 71 corresponding to the plurality of screw holes 62, so that the plurality of screws P can pass through the plurality of fish-eye holes 71 from bottom to top and be directly locked into the plurality of screw holes 62. When the telescopic cover moves, it can drive the two sliders 90 to abut against the two guide rails 81.

[0005] The aforementioned conventional telescopic cover currently uses two Teflon or copper sheets 70 as the support interface. In actual operation, the two Teflon or copper sheets 70 must be machined with multiple fish-eye holes 71 to allow the multiple screws P to be embedded in the multiple fish-eye holes 71, thus preventing the multiple screws P from wearing down the two guide rails 81. However, due to the problem of burrs from drilling and insufficient depth of drilling the multiple fish-eye holes 71, the multiple screws P are prone to protruding and wearing down the two guide rails 81, resulting in unstable quality. This is an existing problem and defect that needs to be overcome and resolved. [Summary of the Invention]

[0006] The inventor is currently engaged in the manufacturing and design of related products. With many years of practical experience and insights, the inventor has actively invested in innovation and improvement in response to the existing problems and deficiencies of the first and second types of traditional telescopic covers.
