The second rail 26 can be longitudinally displaced relative to the first rail 22. The first The second rail 26 has a first end and a second end away from the first end, such as a front end 26a and a rear end 26b. It is worth mentioning that in this embodiment, the X-axis direction is the longitudinal direction (or the length direction or the displacement direction of the slide rail), the Y-axis direction is the transverse direction (or the lateral direction of the slide rail), and the Z-axis direction is the vertical direction ( Or the height direction of the slide rail).

The lock device 28 is arranged adjacent to the second rail 26, and the lock device 28 includes a lock base 40 and a lock element 42.

Preferably, the locking device 28 is arranged at the front end 26a of the second rail 26.

Preferably, adjacent to the inner side of the front end portion 26a of the second rail 26 is connected a fixed base 50, when the second rail 26 is in a folded position, the fixed base 50 is positioned beyond the front bracket 24 The end plate 46 (shown in Figure 1); the fixed base 50 has a hole H (also can be regarded as the second rail 26 has the hole H), the lock base 40 has a connecting section 52 passing through the fixed base The hole H of the base 50 connects the lock base 40 (for example, movably connected) to the fixed base 50. On the other hand, the lock member 42 is arranged on the lock seat 40.

As shown in FIGS. 3 to 5, the lock base 40 is operably in one of an open state K1 (as shown in FIG. 3) and a closed state K2 (as shown in FIG. 5) relative to the second rail 26. Here, the lock base 40 can be rotated relative to the second rail 26 from the open state K1 to the closed state K2; or the lock base 40 can be rotated relative to the second rail 26 from the closed state K2 to the open state Take K1 as an example.

For example, the fastener 62 pivots through a shaft 64 Connected to the front bracket 24, the fastener 62 can move between a locked position C (as shown in FIG. 3) or an unlocked position (not shown). Wherein, when the fastener 62 is in the locking position C, a fastener portion 65 of the fastener 62 is adjacent to the front of the end plate 46 of the front bracket 24. Preferably, the fastener 62 can be held in the locked position C by the elastic force of an elastic part. Since the fastener 62 is a technical category that can be understood by those familiar with the field, for the sake of brevity, it will not be added here. Go into details.

As shown in Figs. 6 and 7, the two slide rail assemblies 20 are mounted to a rack. Specifically, the frame includes at least a pair of machine columns, such as a pair of front machine columns 66a and a pair of rear machine columns 66b, and each front machine column 66a and each rear machine column 66b are installed with a corresponding slide rail assembly. The first rail 22 of the slide rail assembly 20 is installed to the front pillar 66a and the rear pillar 66b through the front bracket 24 and the rear bracket 30, respectively, and the second rail 26 can A carrier 68, such as an electronic device, is carried. The second rail 26 is at the folded position P1 relative to the first rail 22. Wherein, the principle of the front bracket 24 being mounted to the front column 66a and the rear bracket 30 being mounted to the rear column 66b are substantially the same. For example, the front column 66a includes a plurality of mounting holes (for example, a A mounting hole 70a, a second mounting hole 70b, and a third mounting hole 70c are located between the first mounting hole 70a and the second mounting hole 70b), the front bracket 24 can pass through the two mounting members 48 Installed to the first mounting hole 70a and the second mounting hole 70b of the front machine column 66a, and the fastener 62 is in the locking position C and can be locked in front of the front machine column 66a by means of the buckle 65 (as shown in FIG. 7 ). Wherein, the lock base 40 is operatively in the open state K1 relative to the second rail 26. At this time, the second rail 26 can move from the folded position P1 to a first direction relative to the first rail 22. D1 displacement.

As shown in FIG. 8, when the second rail 26 is in the folded position P1 relative to the first rail 22, the lock base 40 is operatively in the closed state K2, so that the threaded portion 56 of the lock 42 can be locked. The lock portion 38 of the front bracket 24 is inserted to keep the load 68 in the frame and cannot move outside the frame arbitrarily. Furthermore, once the lock base 40 is operatively in the closed state K2 relative to the second rail 26, when the threaded portion 56 of the lock 42 is locked into the lock portion 38 of the front bracket 24, the second rail 26 cannot be displaced relative to the first rail 22 from the folded position P1 to the first direction D1. That is, the carrier 68 is fixed at the folded position P1.

As shown in FIG. 9, once the lock seat 40 is no longer in the closed state K2 relative to the second rail 26 (for example, in the open state K1), the second rail 26 can be retracted from the first rail 22. The closing position P1 is displaced in the first direction D1 to an extended position P2 and is located outside the frame. It is worth mentioning that the second rail 26 can be displaced relative to the first rail 22 from the extended position P2 to a second direction D2 opposite to the first direction D1 to the retracted position P1 and return to the rack. .

As shown in FIGS. 10 and 11, the above-mentioned fastener 62 is omitted, wherein the fixed base 50 has a thickness T (as shown in FIG. 10), and the connecting section 52 of the lock seat 40 defines a boundary The connecting space S has a width greater than the thickness T, so that the lock base 40 can be adjusted horizontally relative to the fixed base 50 of the second rail 26. For example, the lock base 40 can be adjusted and displaced from a first lateral position Y1 (as shown in FIG. 10) to a second lateral position Y2 (as shown in FIG. 11).

Preferably, when the lock base 40 is located at the second lateral position Y2 and in the closed state K2, so that the lock 42 is locked into the lock portion 38 of the front bracket 24 (as shown in FIG. 11), the lock One side of the seat 40 and one side of the second rail 26 are substantially located on the same longitudinal plane L. Such an advantage is, for example, that when the second rail 26 is in the folded position P1 relative to the first rail 22, it can be ensured that the lock seat 40 will not be blocked in front of the load 68, for example, the lock seat 40 will not The electronic joints, cables, warning lights, or related signs of the load, etc., arranged in front of the load 68 are blocked, thereby facilitating related maintenance operations of the load 68 or the slide rail by the on-site personnel. Alternatively, the lock base 40 is located at the second lateral position Y2 to facilitate the alignment or locking of the lock member 42 to the lock portion 38 of the front bracket 24. Preferably, the bent section 58 of the lock base 40 can be correspondingly fixed to the front surface of the machine column (for example, the front machine column 66a) (as shown in FIG. 11), which facilitates the installation of the front bracket 24 to the machine column. The tightening effect of the machine column is improved.

Figures 12 to 14 show the configuration of another embodiment of the present invention. The implementation is roughly the same as the previous embodiment. The main difference is that the lock portion 202 of the front bracket 200 is arranged on the buckle portion of the fastener 204, and the lock device 206 is arranged On the second rail 208, the lock base 210 is in the open state K1 at this time, and the lock member 212 is far away from (not corresponding to) the lock portion 202. On the other hand, the figure also shows that when the front bracket 200 is installed on a machine column 214, the lock portion 202 is located in front of the end plate 201 or the machine column 214. Compared with the foregoing embodiment, for example, when the front bracket 24 shown in FIG. 7 is installed on the front cylinder 66a, the lock portion 38 is located at the rear side of the front cylinder 66a. Therefore, the lock 42 of the foregoing embodiment Relative to the position of the lock portion 38 is slightly farther. And this example By moving the lock portion 202 forward to be located in front of the end plate 201 or the machine column 214, the position of the threaded portion of the lock member 212 relative to the lock portion 202 can be shortened.

If the lock member 212 of the lock device 206 is to be locked, the lock base 210 can be manually operated to move, for example, the lock base 210 is pushed by an external force F (as shown in FIG. 14) to make the lock base 210 from the open state K1 Displace laterally to the closed state K2. At this time, the threaded portion of the lock 212 corresponds to the lock 202 (as shown in FIGS. 15 and 16), and the lock 212 can be locked to the lock 202 to be fixed (as shown in FIG. 17). Preferably, the connecting section 211 of the lock base 210 passes through the hole H'of the second rail 208 (as shown in FIG. 15), and the lock base 210 is provided with a feature 216 (for example, a bent portion). When the lock 212 is locked to or corresponds to (not yet locked) in the fixed position of the lock portion 202, the feature 216 of the lock base 210 abuts against the front end 208a of the second rail 208, and the connecting section of the lock base 210 211 abuts against the inner wall of the hole H'of the second rail 208, thereby forming a front and rear blocking relationship; or, even if the lock base 210 and the second rail 208 do not abut, the feature 216 can also shorten the The gap between the lock base 210 and the front end 208a of the second rail 208 makes the second rail 208 extend and displace relative to the front bracket 200, so that the lock base 210 does not have a front end relative to the second rail 208. The gap (or longitudinal gap) of the rear displacement causes the front and rear displacement of the lock seat 210 relative to the second rail 208.

As shown in FIG. 18 and FIG. 19, the configuration of another embodiment of the present invention is substantially the same as the foregoing embodiment, and the main difference lies in the structural configuration relationship between the second rail and the lock device. Specifically, the second rail 300 includes a first wall 302a, a second wall 302b, and a longitudinal wall 304 connected to the first wall of the second rail 300. Between a wall 302a and a second wall 302b, the longitudinal wall 304 of the second rail 300 has a first side M1 and a second side M2 in opposite positions. On the other hand, the lock seat 306 of the lock device is movably installed on the second rail 300, and the lock member 308 is arranged on the lock seat 306.

Preferably, the longitudinal wall 304 of the second rail 300 has a predetermined space 309 connecting the first side M1 and the second side M2, and the lock base 306 can be opposed to the longitudinal direction of the second rail 300 through the predetermined space 309 The wall 304 is displaced laterally, wherein the predetermined space 309 is a hole, but the implementation is not limited.

Preferably, the slide rail assembly further includes an auxiliary member 310 movably installed on the first side M1 of the longitudinal wall 304 of the second rail 300, and the auxiliary member 310 has a supporting portion 312 adjacent to the predetermined space 309, And the supporting portion 312 of the auxiliary member 310 has a thickness T'; on the other hand, the lock base 306 has a connecting section 314, and the connecting section 314 of the lock base 306 defines a connecting space S'with a boundary for accommodating The supporting part 312 of the auxiliary member 310, wherein the width in the connecting space S'is greater than the thickness T', so that the lock base 306 can be transversely relative to the auxiliary member 310 (or the longitudinal wall 304 of the second rail 300) Adjust position.

Preferably, the position of the connecting section 314 of the lock seat 306 corresponds to the predetermined space 309 of the longitudinal wall 304 of the second rail 300.

Preferably, the auxiliary member 310 and the longitudinal wall 304 of the second rail 300 can move longitudinally relative to each other within a limited range through the combination of at least one first connection feature 316 and the second connection feature 318. Here, the auxiliary member 310 has a first connection feature 316, and the first connection feature 316 has a boundary, for example. On the other hand, the second connecting feature 318 is, for example, a protrusion (such as a pin, rivet, or bolt) that can penetrate a part of the longitudinal feature and connect to the second rail The first side M1 of the longitudinal wall 304 of 300 is used to install the auxiliary member 310 to the second rail 300.

The edge walls 324 block each other to keep the lock base 306 in the closed state (as shown in FIG. 20), so that the lock base 306 cannot move from the closed state to the open state.

As shown in Figure 22 and Figure 23, when an external force F'is applied to the lock base 306, the lock base 306 can move from the above-mentioned second rail 300 to the longitudinal wall 304 of the second rail 300. The lateral position Y2' moves laterally to the first lateral position Y1'. Furthermore, the lock base 306 can be displaced from the second lateral position Y2' to the first lateral position Y1' through the predetermined space 309. When the lock base 306 is located at the first lateral position Y1', the side 320 of the lock base 306 extends beyond the second side M2 of the longitudinal wall 304 of the second rail 300. At this time, the connecting section of the lock base 306 The bending feature 322 of 314 no longer blocks each other with the edge wall 324 of the predetermined space 309 of the longitudinal wall 304 of the second rail 300 (as shown in FIG. 23).

The edge walls 324 of the predetermined space 309 block each other, and the lock base 306 can be operated from the closed state to rotate in a predetermined direction R'to the open state (as shown in FIG. 25). Furthermore, when the lock base 306 moves from the closed state to the open state, a part 317 of the connecting section 314 of the lock base 306 (for example, the wall surface in the connecting space S'of the connecting section 314) The auxiliary member 310 is driven from the first longitudinal position L1 (as shown in FIG. 24) to a second longitudinal position L2 (as shown in FIG. 25).

As shown in FIG. 26, the second side M2 of the second rail 300 can be loaded with a load 328. When the second rail 300 is located at a predetermined position relative to the first rail 326, such as a folded position, the lock base 306 is operatively located at the second lateral position Y2' and in the closed state, wherein, due to the lock base The side portion 320 of the 306 does not exceed the second side M2 of the longitudinal wall 304 of the second rail 300. Therefore, the side portion 320 of the lock seat 306 is not in contact with a side surface of the load 328 carried by the second rail 300. 330 interferes. The advantage of this is, for example, that the side surface 330 of the carrying object 328 can be as flat as possible with the second side M2 of the longitudinal wall 304 of the second rail 300, so as to avoid the side surface 330 of the carrying object 328 and the second side M2. There is a lateral gap between the second side M2 of the longitudinal wall 304 of the second rail 300. Therefore, when the carrying object 328 is to be installed on the second rail 300, it is advantageous for a fastener (such as a screw or bolt) to lock the side surface 330 of the carrying object 328 to the longitudinal wall of the second rail 300. The second side of 304 M2.

Furthermore, when the second rail 300 is located in the folded position relative to the first rail 326, and the lock base 306 is in the closed state, the lock member 308 (the threaded part) can be correspondingly locked into the front support The lock portion of the frame 332 (because this part has been disclosed in the first two embodiments, for the sake of brevity, it will not be repeated here). If the carrier 328 is to be pulled out from the front cylinder 340, the locking relationship between the lock 308 and the lock portion of the front bracket 332 is released, and the carrier 328 can be pulled out.

Preferably, the fastener 334 of the slide rail assembly is movably mounted on the front bracket 332. When the fastener 334 is in the locked position, the fastener 336 of the fastener 334 is adjacent to the end of the front bracket 332. The plate 338 or the front of the front pillar 340 can be used to lock the front pillar 340.
