The micro linear rail 1000 includes a guide rail 100, a sliding module 200 slidably disposed on the guide rail 100, and two end cap modules 300 respectively disposed at two opposite ends of the sliding module 200 and slidably sleeved on the guide rail 100.

It should be noted that, in the embodiment, two end cap modules 300 are combined with the above-mentioned components for illustration, but in other embodiments not shown in the present invention, each end cap module 300 can also be applied separately (for example, sold) or combined with other components for use, and is not limited to the embodiments. The structure of each component of the micro wire track 1000 and the connection relationship thereof will be described below.

Referring to fig. 1 to fig. 3, the guide rail 100 is elongated, and a length direction of the guide rail 100 is defined as a sliding direction S. Two rolling grooves 11 parallel to the sliding direction S are formed in the upper half of the guide rail 100 on opposite sides thereof.

The sliding module 200 is slidably arranged to the above-mentioned rail 100 and the sliding module 200 has two mating ends 201 on opposite sides.

More specifically, the sliding module comprises a circulating seat 21, a sliding block 22, two sets of rolling elements 23 and two retainers 24. The circulation base 21 is a one-piece structure formed integrally, and the circulation base 21 includes two circulation portions 211 and two connecting pieces 212 connected to opposite ends of the two circulation portions 211, respectively, and the two mating ends 201 are located on surfaces of the two connecting pieces 212 away from each other.

Further, each of the circulating portions 211 has a receiving tube 2111 and two turning rails 2112 respectively connected to opposite ends of the receiving tube 2111. The path of the turning track 2112 is substantially semicircular.

The slider 22 is substantially rectangular and the length of the slider 22 is less than the length of the guide rail 100. More specifically, the slider 22 is concavely formed with a fitting groove 221, that is, the cross section of the slider 22 perpendicular to the length direction thereof is substantially pi-shaped, and the slider 22 is slidably disposed on the guide rail 100 with the fitting groove 221. Further, the fitting groove 221 of the slider 22 has two guide surfaces 222 facing each other, and the two guide surfaces 222 are adjacent to the two circulating portions 211, respectively. Wherein each set of mutually adjacent guide surfaces 222 and circulation portions 211 can form a circulation channel C together with two of the connecting sheets 212. That is, the slide module 200 of the present embodiment has two circulation paths C (see fig. 11).

More specifically, as shown in fig. 7 and 9, a rolling section 2221 is formed on each of the two guide surfaces 222 of the engagement groove 221 at a position facing each of the rolling grooves 11, and each of the rolling grooves 11 and the opposite rolling sections 2221 thereof are substantially circular in cross section perpendicular to the sliding direction S (as shown in fig. 9), but the present invention is not limited thereto.

With reference to fig. 2, fig. 3, fig. 6, and fig. 7, the sliding block 22 is inserted into the circulating seat 21, so that the sliding block 22 and the circulating seat 21 are slidably disposed on the guide rail 100. The two circulating portions 211 are respectively located at opposite sides of the guide rail 100, and the two accommodating tube bodies 2111 are located at the outer side of the engaging groove 221 (or the slider 22) and the length direction thereof is parallel to the sliding direction S. Furthermore, in each of the circulation portions 211, one end of each of the two turning rails 2112 is connected to the two ends of the accommodating tube 2111, and the other end of each of the two turning rails 2112 is connected to the two ends of the corresponding rolling section 2221.

Furthermore, as shown in fig. 11, two sets of rolling members 23 are respectively rollably received in the two circulation passages C. In the present embodiment, each group of the rolling elements 23 includes a plurality of balls 231, and the plurality of balls 231 are adjacent to each other and rollably disposed in the corresponding circulation channel C, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the rolling elements 23 may also include a chain belt and a plurality of balls or rollers disposed on the chain belt.

In the present embodiment, the above-mentioned matching manner between the slider 22 and the guide rail 100 is to take the example that the rolling member 23 is rollably clamped between the slider 22 and the guide rail 100, but the present invention is not limited thereto. Wherein the length direction of the slider 22 is parallel to the length direction of the guide rail 100 (i.e., the sliding direction S).

Further, the two guide surfaces 222 of the slider 22 are a plurality of balls 231 each sandwiching two sets of rolling elements 23 with the stopper sections 241 of the two retainers 24. As shown in fig. 9, the center point of each ball 231 clamped between the sliding block 22 and each limiting segment 241 is located on a plane P where the two limiting segments 241 are located. Therefore, the sliding block 22 and the retainer 24 can generate a good positioning effect on the rolling element 23, so as to avoid the situation that the ball 231 is easy to shake or fall off the micro-linear rail 1000.

Referring to fig. 1 to 5, two end cap modules 300 are respectively mounted at the two mating ends 201 of the sliding module 200 and slidably sleeved on the guide rail 100. Each of the end cap modules 300 includes a cap 31, a dust cap 32, and two screws 33.

As shown in fig. 11, the two circulating portions 211 of the circulating seat 21, together with the guide rail 100, the slider 22 and the two covers 31, can define two circulating channels C. Further, each cover 31 is recessed with two substantially U-shaped turning portions 316 (please refer to fig. 5) at a portion facing the slider 22 (or the circulation seat 21), and the two turning rails 2112 and the accommodating tube 2111 of each circulation portion 211 can be matched with the corresponding rolling section 2221 of the slider 22, the corresponding rolling groove 11 of the guide rail 100, and the corresponding turning portions 316 of the two covers 31, thereby forming one circulation channel C.

Referring to fig. 4 and 5, in each of the end cap modules 300, the dust cap 32 is shaped like a sheet, and the dust cap 32 is disposed in the receiving groove 313 of the cover 31 to seal the outer end surface 312 of the cover 31, so as to reduce the dust from the outside entering the inside of the micro wire track 1000. In addition, in the present embodiment, the shape of the dust cover 32 corresponds to the shape of the receiving groove 313 of the cover 31, so that the dust cover 32 can be fixedly embedded in the receiving groove 313, but the present invention is not limited thereto.

In the present embodiment, two of the screws 33 are flat cross self-tapping screws, but the present invention is not limited thereto. Furthermore, each of the end cap modules 300 preferably does not include any screws other than the two screws 33.

According to the above configuration, the two end cap modules 300 of the micro wire rail 1000 of the present embodiment can be respectively assembled to the two mating ends 201 of the sliding module 200 by two screws 33 without any other screws besides the two screws 33, thereby reducing the complexity of device assembly and the cost of device assembly.

More specifically, in each of the end cover modules 300, two screws 33 are inserted through the corresponding connecting sheet 212 and locked on the sliding block 22, and two positioning pillars 314 are located outside the two screws 33. As shown in fig. 4, the distance D1 between the two positioning posts 314 is 120% to 150% of the distance D2 between the two screws 33, and more preferably, the distance D1 between the two positioning posts 314 is 130% to 140% of the distance D2 between the two screws 33. Therefore, the miniature linear rail 1000 can have better structural strength and bearing effect.
