Referring to fig. 1 to 8, the present embodiment provides a linear guide 100. As shown in fig. 1 and 2, the linear slide 100 comprises an elongated rail 1, a slider module 2 slidably disposed on the elongated rail 1, and two dust-proof modules 3 mounted on opposite ends of the slider module 2 and slidably disposed on the elongated rail 1.

As shown in fig. 1 and 2, the long rail 1 has a longitudinal direction LD, and the long rail 1 has one end face S11 at each of opposite ends of the longitudinal direction LD. Further, the long rail 1 includes a plurality of contact side surfaces S12 each parallel to the longitudinal direction thereof, the plurality of contact side surfaces S12 being located between the two end surfaces S11, and the plurality of contact side surfaces S12 being located on opposite sides of the long rail 1, respectively, two by two. Furthermore, the linear guide 100 further includes a plurality of balls (not shown) for rolling between the slider module 2 and the long rail 1, but the balls are not modified in this embodiment, and thus the description thereof is omitted.

It should be noted that, although the above-mentioned long rail 1, the slider module 2 and the two dust-proof modules 3 are collectively defined as the linear guide 100 in the present embodiment, the present utility model is not limited thereto. For example, the dust-proof module 3 may be used alone (e.g., in practice, manufacture, vending, etc.) or in combination with other components.

Further, since the two dust-proof modules 3 are substantially identical or symmetrical in configuration in the present embodiment, only the configuration of a single dust-proof module 3 will be described below for convenience of explanation. However, in other embodiments of the utility model not shown, the two dust-proof modules 3 may also be configured differently from each other.

Referring again to fig. 1, 3 and 4, the dust-proof module 3 includes a main body 31 fixed on the slider module 2 and a flexible member 32 connected to the main body 31. The main body 31 has an inner side surface facing the long rail 1, and the main body 31 substantially covers one end surface of the slider module 2 (in the longitudinal direction LD). The main body 31 further has three grooves G31 in the present embodiment, two of the grooves G31 are located on opposite sides (left and right sides in fig. 1) of the main body 31, the other groove G31 is located on a side of the main body 31 away from the elongated rail 1, and a fixing hole (not shown) is further formed in each groove G31 for a locking member (not shown) to pass through, so that the dust-proof module 3 is fixed on the slider module 2, but the utility model is not limited thereto. For example, in other embodiments, not shown, three grooves G31 may be omitted.

Next, as shown in fig. 4 to 6, the main body 31 is made of flexible material in the present embodiment, and the main body 31 is integrally connected to the flexible member 32 at the inner side surface, that is, the main body and the flexible member 32 have flexible material characteristics in the present embodiment, but the present utility model is not limited thereto. For example, in other implementations not shown, the body 31 may be made of other materials (e.g., non-flexible materials) that are different from the physical properties of the flexible member 32.

As shown in fig. 4 to 6, the flexure 32 is adjacent to three of the grooves G31 in the present embodiment, and the flexure 32 can contact the plurality of contact sides S12 of the elongate rail 1 in a non-rigid manner. Specifically, the flexible member 32 has an interference lip 321, a line contact lip 322 disposed at a distance from the interference lip 321, and a dust receiving space SP (as shown in fig. 8) between the interference lip 321 and the line contact lip 322. The flexible member 32 can form a plurality of lines of protection against external dust on the long rail 1 through the interference lip 321, the line contact lip 322, and the dust receiving space SP.

Wherein the interference lip 321 is located on a side of the body 31 (in the length direction LD) remote from the slider module 2, and an inner edge of the interference lip 321 geometrically mates with the end face S11, i.e., a side of the interference lip 321 facing the elongate rail 1 has a contour substantially similar to that of the elongate rail 1. In more detail, as shown in fig. 6, the inner edge of the interference lip 321 extends obliquely from the main body 31 along one side of the length direction LD, such that the end portion of the interference lip 321 is far away from the slider module 2, and a first angle θ1 is formed between the inner edge of the interference lip 321 and an imaginary plane (not labeled) parallel to the contact side S12 (when the dust-proof module 3 is not in contact with the elongated rail 1). In addition, as shown in fig. 8, when each of the dust-proof modules 3 is disposed on the elongated rail 1 by the slider module 2, the interference lip 321 can interfere with the plurality of contact sides S12, that is, the interference lip 321 extends long enough to interfere with the plurality of contact sides S12.

Wherein when the interference lip 321 interferes with the plurality of contact side surfaces S12, the tip portion of the interference lip 321 slidably contacts each of the contact side surfaces S12. That is, the friction force generated by the interference lip 321 and each contact side S12 during the interference does not affect the movement of the slider module 2.

In a practical application, the width W321 of the end portion of the interference lip 321 along the length direction LD of each contact side S12 is preferably between 0.4 mm and 0.8 mm (as shown in fig. 8), so as to provide the best dust-proof effect without affecting the movement of the slider module 2. In addition, when the interference lip 321 has not contacted the contact sides S12 (i.e., the dust module 3 is not mounted on the dust module 3 yet), the end portion of the interference lip 321 has a height HS as an interference amount, which is preferably between 0.2 mm and 0.6 mm (as shown in fig. 8), so as to be a flexible margin and a reasonable loss portion of the interference lip 321.

As shown in fig. 4 to 6, the line contact lip 322 is located on the side of the main body 31 facing (or adjacent to) the slider module 2, and the inner edge of the line contact lip 322 geometrically engages the end face S11, that is, the profile of the side of the line contact lip 322 facing the long rail 1 is substantially similar to the profile of the long rail 1. In more detail, as shown in fig. 6, the inner edge of the line contact lip 322 extends obliquely from the main body 31 along the other side of the length direction LD, and a second angle θ2 (greater than the first angle θ1) is formed between the inner edge of the line contact lip 322 and the imaginary plane (when the dust-proof module 3 is not in contact with the long rail 1). Furthermore, as shown in fig. 8, when each of the dust-proof modules 3 is disposed on the long rail 1 by the slider module 2, the extending length of the line contact lip 322 is enough to make the distal end of the line contact lip 322 contact with the plurality of contact sides S12 with a minimum area (that is, substantially linearly), that is, the line contact lip 322 contacts the long rail 1 in a line contact manner.

Accordingly, when the slider module 2 moves the dust-proof modules 3, the friction force between the wire contact lip 322 and the contact side surfaces S12 can be minimized, and dust can be ensured to pass through between the wire contact lip 322 and the contact side surfaces S12, that is, the friction force between the wire contact lip 322 and the contact side surfaces S12 is smaller than the friction force between the interference lip 321 and the contact side surfaces S12.

It should be noted that, as used herein, the term "line contact" refers to a contact region having a width W322 of less than 0.06 mm (as shown in fig. 8), i.e., any component having a width greater than 0.06 mm when contacting the track is not a line contact lip 322 of the present utility model.

In actual use, the interference lip 321 interferes with each of the contact sides S12 to serve as a first line of defense. When dust passes through the interference lip 321 carelessly, the dust can be stopped in the dust accommodating space SP by the line contact lip 322 to prevent entering the inside of the slider module 2, i.e., the line contact lip 322 takes line contact as a second line of defense. Preferably, the first angle θ1 is between 10 and 20 degrees, and the second angle θ2 is between 20 and 40 degrees. Accordingly, when each of the dust-proof modules 3 is disposed on the long rail 1 through the slider module 2, the dust-proof effect of each of the dust-proof modules 3 can be optimized.

In order to avoid excessive interference of the interference lip 321 with the contact sides S12 due to unexpected conditions, the flexible member 32 of each dust module 3 can further include a pressure relief structure 323. Specifically, as shown in fig. 8, the interference lip 321 is integrally connected to the main body 31 through the pressure reducing structure 323, and the pressure reducing structure 323 includes a groove 3231 and a slope portion 3232 connecting the groove 3231 and the interference lip 321. The inclined surface portion 3232 is movable toward the groove 3231 so as to be able to return when the interference lip 321 interferes with the plurality of contact side surfaces S12, so that the interference lip 321 can be buffered by the inclined surface portion 3232 of the pressure reducing structure 323.

Viewed more finely, the length L323 of the relief structure 323 along the length direction LD is smaller than the length L321 of the interference lip 321 along the length direction LD, and the area where the relief structure 323 is orthographically projected to the long rail 1 is located in the area where the interference lip 321 is orthographically projected to the long rail 1. That is, the relief structure 323 is located on the same side of the flexure 32 as the interference lip 321, and the relief structure 323 is located at a position not exceeding the interference lip 321. Accordingly, one end of the interference lip 321 adjacent to the line contact lip 322 can be used as a fulcrum, and the other end of the interference lip 321 can be used to link the bevel portion 3232 and buffer with the groove body 3231.

It should be noted that the depth D3231 of the groove 3231 along the length direction LD is preferably substantially equal to the height H3232 of the inclined surface portion 3232 along the length direction LD (i.e. the depth D3231 and the height H3232 are 1:1), and an included angle θ3 between a wall (not labeled) of the groove 3231 parallel to the length direction LD and the inclined surface portion 3232 is 30 to 45 degrees. Accordingly, the relief structure 323 can provide an appropriate cushioning effect without affecting the interference of the interference lip 321 with the contact side S12. Similarly, when the main body 31 is made of flexible material, the three grooves G31 can provide a pressure reducing effect.

In addition, referring again to fig. 8, in order to avoid the occurrence of excessive stress concentration between the interference lip 321 and the wire contact lip 322, the flexible member 32 of each dust module 3 can further include a buffer plate 324. Specifically, the buffer plate 324 is located between the interference lip 321 and the line contact lip 322, and the buffer plate 324 integrally connects the interference lip 321 and the line contact lip 322. The buffer plate 324 has a buffer surface S324 on a side facing the dust receiving space SP, and the buffer surface S324 is non-parallel to the inner edge of the interference lip 321 and the inner edge of the line contact lip 322 to block the inner edge of the interference lip 321 from being directly connected with the inner edge of the line contact lip 322.

Preferably, the buffer surface S324 is parallel to the contact side surface S12 corresponding to the position, and the length L324 of the buffer surface S324 along the length direction LD is preferably between 0.05 mm and 0.2 mm.
