1345035 VI. Description of the Invention: [Technical Field of the Invention] The present invention relates to a "linear slide return system" for linear sliding, and more particularly to a linear sliding handle for lightweight and micro-small use. The design is improved for the cover and end cover of the reflow system fitted on the slider. [Prior Art] A linear slider for moving the slider is provided, which reduces the friction coefficient of the slider movement and reduces the noise generated when the slider moves, so that a back turbulence system is provided between the slider and the slide rail to provide ball circulation scrolling. The reflow system includes two return ends disposed at two ends of the slider, a plurality of load paths are located between the slider and the sliding block, and a plurality of no-load return paths pass through the slider, and the return end cover is disposed on the cover The surface reflow path is connected to each of the load path and each non-load return path to form a one-dimensional circulation path, and the slider and the slide are metal designs due to the necessary load. There are three main designs for the surface recirculation path on the recirculating path and the design of each reflow path: ° US Patent No. US59115G9, as shown in Figure 15, the curved path of the circulation path and the return path The method is formed by a buried injection method, and the injection molding machine is formed on the outer side of the bottom 4 of the slider 61, and the curved surface return path and the return path 62 are formed on the slider μ directly in the injection molding die, and then slipped. The ends of the block 61 are combined with the end cover of the <IL path, and the design of the structure has the following disadvantages: each metal slider 61 needs to be embedded in the mold for injection molding, so the slider 1 The processing precision must be improved and the mold is matched. The reliance * is not covered by the domain. 4 1345035. In the assembly portion 21C, the outer reflow block 42C is provided with a semi-return path continuing the second curved surface return path 41C. 43C, the one end cover 4〇c❾ outer reflow block 42c is a second-surface reflow path batch combination of the cover 4GC, the combination is a bump 44C and a groove 45C_, and the inner reflow block 32c and the The outer reflow block 42C is combined to make it located The two-half return path 33c on the outer side of the slider 2 〇{] is divided into two ends in the assembly portion 21C, and the two ends of the contact path and the two ends of the load path are respectively connected And forming a 裒 裒 path with the return path, the load path and the two curved surface return path, and the end surface of the end cover 40C is provided with a positioning hole 3C corresponding to the positioning hole 3 盖板 of the cover plate 3 〇 c, The positioning hole 37C is traversed by the locking member 47C, so that the locking member 47c f is locked to the two ends of the slider 20c. The plurality of reflow elements 50C are arranged to circulate in the respective circulation paths. The end cover 40 (or 40A or 40B or 40C) of each of the above embodiments is provided with an oil hole 48' for the injection hole 48 to provide oil injection into the oil can or oil pipe and the end cover 40 (or 40A) Or the inner portion of the oil hole 48 is provided with an oil passage 49 to each of the curved surface return paths for supplying the oil originally injected through the oil hole or the oil pipe to the respective reflow elements 5 of the curved return path ( Or 5 (10) or 5 (10) or 50C) to increase the lubrication of the reflow element 50 (or 5 〇 A or 5 〇 β or 5 〇〇 with the circulation path, and reduce the friction coefficient, increasing the service life of each element. The structure of the present invention has the following creasibility: (1) The cover plate 30 and the end cover 40 of the present invention are generally plastic injection, and the processing method can reduce the processing cost and facilitate rapid mass production. 15 1345035 (2) Providing a no-load return path in the circulating path in which the reflow element 50 rolls, the combination of the cover plate 30 and the end cap 40 is such that the inner reflow block 32 and the outer reflow block 42 between the cover plates 40 are in a semi-return path. 33, 43 form a return path, the resulting return path For the plastic material, when the roller element of the reflow element is provided, the contact noise between the metal and the metal can be avoided, and the use is quieter. (3) The slider of the present case utilizes the cover 30 and the end cover. The combination of 40, and the inner reflow block 32 and the outer reflow block 42 are disposed on the cover plate 30 and the end cover 4, and are formed by a method of embedding and setting out, that is, a return path of a plastic material, so the slider The general precision can be manufactured without increasing the precision matching with the mold, which can reduce the processing cost of the slider. 16 1345035 [Simplified description of the drawings] Fig. 1 is a three-dimensional combination diagram of an embodiment of the present invention Fig. 2 is a perspective exploded view of an embodiment of the present invention.
