[0061] The applicant hereby clarifies that throughout this specification, including the embodiments described below and the claims of the patent application, all directional terms are based on the directions shown in the accompanying drawings. Secondly, in the embodiments and drawings described below, the same reference numerals represent the same or similar elements or structural features thereof.

[0062] Please refer to the following first. Figure 1 and Figure 2The linear transmission module 1 shown in the figure includes a base 2, with a bearing housing 3 connected to each end of the base 2. A timing pulley 4 is installed inside each bearing housing 3, and two timing pulleys 4 are interconnected by a timing belt 5. One of the timing pulleys 4 is connected to a drive source (e.g., a motor, not shown in the figure). Additionally, two parallel slide rails 6 are installed inside the base 2, and a cover belt 7 is installed on the top surface of the base 2 above the timing belt 5. The two ends of the cover belt 7 are fixed to the two bearing housings 3, providing dust protection for the components inside the base 2 (e.g., the timing belt 5).

[0063] Please refer to the following: Figure 3 and Figure 4 The slide 10 provided by this utility model includes a slide body 20, a protective cover 60, and two end caps 70.

[0064] The slide body 20 has an upper seat 30, a lower seat 40, and four sliders 42. The upper seat 30 and the lower seat 40 are assembled together by screws, and the four sliders 42 are assembled to the bottom surface of the lower seat 40 by screws and are arranged in pairs. The upper seat 30 has two side support parts 31, a middle support part 32, and four guide block support parts 33. The two side support parts 31 are arranged in a parallel manner, the middle support part 32 is integrally connected between the two side support parts 31, and the four guide block support parts 33 are located at two opposite ends of the middle support part 32 and are integrally connected between the side support parts 31 and the middle support part 32 in pairs. The inner surfaces of the two side support parts 31 together form a receiving groove 35 (e.g., Figure 7 As shown), the receiving groove 35 extends in a straight line from one end of the two side support portions 31 along the length direction of the slide body 20 to the other end of the two side support portions 31.

[0065] like Figure 4 As shown, the slide body 20 also has four upper guide blocks 44 and four lower guide blocks 46. The four upper guide blocks 44 are assembled to the four guide block support portions 33 of the upper seat body 30 by screws. The four lower guide blocks 46 are assembled to the bottom surface of two lower guide block fixing frames 48 by screws and are arranged in pairs. The two lower guide block fixing frames 48 are then assembled to the two opposite ends of the side support portion 31 by screws.

[0066] like Figure 4 and Figure 6As shown, the slide body 20 also has two belt adjustment seats 50. The two belt adjustment seats 50 are located at two opposite ends of the lower seat body 40 and each has a lower clamp 51, an upper clamp 52, and an adjusting bolt 53. The lower clamp 51 is located on the top surface of the lower seat body 40. The upper clamp 52 is assembled to the top surface of the upper clamp 52 by screws and cooperates with the lower clamp 51 to clamp one end of the timing belt 5 in the middle. The adjusting bolt 53 passes through a through hole 522 of the upper clamp 52 and is screwed into an adjusting screw hole 322 of the middle support part 32 of the upper seat body 30. Therefore, when the adjusting bolt 53 is tightened or loosened, the lower clamp 51 and the upper clamp 52 can be driven to simultaneously tighten or loosen the timing belt 5, thereby achieving the effect of adjusting the tension.

[0067] The two opposite sides of the cover 60 are embedded in the receiving groove 35 of the slide body 20 and cover the upper guide block 44, the lower guide block 46 and the belt adjusting seat 50 of the slide body 20. Figure 6 As shown, the cover 60 has two opposite ends 62, which protrude from the two opposite ends of the slide body 20.

[0068] Two end caps 70 are assembled to the two opposite ends of the two side support portions 31 of the upper body 30 by means of screws. Figure 5 and Figure 6 As shown, each end cap 70 has a positioning groove 72 on one side facing the slide body 20. The positioning grooves 72 of the two end caps 70 respectively position the two ends 62 of the cover 60, so that the cover 60 is fixed to the slide body 20.

[0069] When assembling with other components, such as Figure 2 and Figure 6 As shown, the slide body 20 is mounted on two slide rails 6 with four sliders 42 and the two ends of the timing belt 5 are fixed by two belt adjusting seats 50. In addition, the cover belt 7 passes under the two end caps 70 and is guided by two upper guide blocks 44 and two lower guide blocks 46 to cross over the upper seat body 30. Therefore, when the drive source drives the timing belt pulley 4 connected to it to rotate, the driven timing belt pulley 4 will drive the other timing belt pulley 4 to rotate through the timing belt 5, thereby driving the slide 10 to move back relative to the base 2.

[0070] It is worth mentioning that, such as Figure 7 and Figure 8As shown, the slider body 20 and the cover 60 satisfy the following relational expressions: W / W1=101%~115%, H / H1=101%~115%, H2>H1, wherein W is the width of the accommodating groove 35, W1 is the width of the cover 60, H is the height of the accommodating groove 35, H1 is the height of the cover 60, and H2 is the height of the positioning groove 72. Through the above relational expressions, the accommodating groove 35 and the positioning groove 72 can be adapted to work with covers 60 of different specifications.

[0071] As Figures 3-4 and Figures 6-8 shown, the slider body 20, the cover 60 and the end caps 70 satisfy the following relational expressions: L<L1, and L1<2D+L, and W2≧W1, wherein L is the length of the slider body 20, L1 is the length of the cover 60, D is the depth of the positioning groove 72, W1 is the width of the cover 60, and W2 is the width of the positioning groove 72. Through the above relational expressions, the slider body 20, the cover 60 and the two end caps 70 are staggered and overlapped with each other, so as to improve the sealing effect.

[0072] On the other hand, as Figure 5 shown, a side surface of each end cap 70 facing the slider body 20 is further provided with three cover support portions 74 arranged at intervals below the positioning groove 72 (actually at least one is sufficient), a top surface of each cover support portion 74 is provided with at least one wedge-shaped portion 76. After the end portion 62 of the cover 60 is fitted into the positioning groove 72 of the end cap 70, the wedge-shaped portion 76 of the end cap 70 will upwardly abut against the end portion 62 of the cover 60, so that the cover 60 is compressed and fixed. In this way, on one hand, the sealing performance can be enhanced, and on the other hand, the resonance phenomenon of the cover 60 caused by assembly gaps can be reduced.

[0073] In summary, after removing the end cap 70 on one side, the cover 60 can be pulled out from the accommodating groove 35 of the slider body 20 along the length direction of the slider body 20, so that the belt adjustment seat 50 is exposed. In this way, it is not necessary to remove the workpiece locked on the slider body 20, which facilitates maintenance, upkeep or adjustment of related components (such as the timing belt 5), thereby achieving the purpose of improving maintenance convenience.
