Slide rail fixing device

The invention relates to a slide rail fixing device.

Slide rails are widely used between two items that move relatively, such as drawers and cabinets or tables, and between servers and cabinets.

A common servo slide rail is generally a three-section slide rail, which usually includes an inner rail, a middle rail and an outer rail. The outer rail is fixed on the support frame of the cabinet, and the inner rail is fixed on the side of the server. The middle rail is connected as a load rail between the inner rail and the outer rail to extend the movable range of the server, and the inner rail and the middle rail can slide back and forth relative to the outer rail along the axial direction of the outer rail Therefore, the servo can be freely pulled out or pushed back to the cabinet through the slide rails.

The internal rail and the servo are usually locked by a plurality of screws, and a tool such as a screwdriver is used, and the installation and disassembly operations are complicated.

In view of the above, it is necessary to provide a rail fixing device that is easy to install and disassemble.

A slide rail fixing device is used for fixing a slide rail to a server, and a side of the server is provided with a protruding bolt, the slide rail includes a main body wall and a flange extending from a side edge of the main body wall. The main body wall defines a card slot for receiving the protruding bolt, the edge of the card slot is provided with a diagonal sliding block, and the sliding rail fixing device comprises a pivoting rail a stopper for the main body wall, the stopper member includes a stopper portion and an elastic portion, the elastic portion abuts against the flange of the slide rail for resetting the stopper member, and the stopper member defines a receiving hole The slanting slider for accommodating the slide rail, the latching bolt of the server is received in the slot of the slide rail, and the stopping portion of the stopping member blocks the latching bolt in the slot, so that the sliding rail is fixed to the sliding rail The servo rotates the stop member, and the stopping portion of the stopping member slides along the inclined slider of the sliding rail and elastically deforms until the stopping portion of the stopping member and the main body wall of the sliding rail The distance between the two can cause the bolt to pass, and the servo is moved to release the bolt from the card slot.

Compared with the prior art, the rail fixing device uses the stopper to block the protruding bolt of the servo in the slot of the sliding rail, and can rotate the stopper to make the stopper and the bolt Separating, so that the loading and unloading process of the server relative to the slide rail is convenient and fast.

1 is a perspective exploded view of a preferred embodiment of a slide rail fixing device, a slide rail and a servo of the present invention.

2-5 are perspective assembled views of the components shown in Fig. 1 and indicate different states of use, respectively.

Referring to FIG. 1, a preferred embodiment of the slide rail securing device of the present invention is used to secure a slide rail 20 to a servo 10 that includes a stop member 30.

A protruding bolt 11 is fixed to the side of the server 10. The protruding bolt 11 forms a neck portion 111 and a head portion 112 having a size larger than the neck portion 111. The boss 11 can be riveted to the server 10.

The slide rail 20 is an elongate body having a generally "C" shape in cross section and includes a body wall 22. The body wall 22 includes a first side 222 facing away from the server 10 and a second side (not shown) facing the server 10. The two sides of the body wall 22 extend toward the first side 222 to form a flange 23 , and a groove 232 is formed between each flange 23 and the body wall 22 . The main body wall 22 defines a card slot 24 along the longitudinal direction of the slide rail 20 adjacent to one end thereof. The card slot 24 includes a large end 242 and a small end 244 that communicate with each other. The body wall 22 protrudes from the edge of the large end 242 of the card slot 24 toward the first side 222 by a downwardly rising diagonal slider 25. The main body wall 22 defines a fixing hole 26 near the card slot 24 . The main body wall 22 is further provided with a convex hull 27 in the vicinity of the fixing hole 26.

The stopper 30 is integrally formed by an elastic metal piece, and includes a main body portion 32, an elongated pivot portion 34 extending from an upper portion of one end of the main body portion 32, and extending from the other end of the main body portion 32. The stopper portion 35 and the lower portion from one end of the main body portion 32 surround the elastic portion 36 formed by the pivot portion 34. An upper side edge of the main body portion 32 is convexly formed to form an operating portion 322. The retaining member 30 defines a receiving hole 38 at a position between the main body portion 32 and the stopping portion 35. A through hole 342 is defined in an end of the pivoting portion 34 away from the main body portion 32. The elastic portion 36 has a U shape and is disposed around the pivot portion 34. In this embodiment, the pivoting portion 34 and the elastic portion 36 are formed by punching a U-shaped groove on the stopper 30. A portion of the elastic portion 36 located on the upper side of the pivot portion 34 is bent toward one side to form a resilient piece 362. The end of the elastic piece 362 is bent toward the other side to form a latch 364.

Referring to FIG. 2 , when assembling, a rivet 40 is passed through the through hole 342 of the 30 and fixed to the fixing hole 26 of the sliding rail 20 , and the stopper 30 is pivotally fixed to the sliding rail 20 . And abuts against the first side 222 of the body wall 22 of the slide rail 20. The elastic piece 362 is engaged with a folded edge 23 of the sliding rail 20, and the latch 364 at the end of the elastic piece 362 is inserted into the corresponding groove 232 of the sliding rail 20. The inclined slider 25 of the main body wall 22 of the slide rail 20 is accommodated in the stop The member 30 is received in the hole 38. The convex hull 27 on the main body wall 22 of the slide rail 20 will push against the elastic portion 36 of the stopper 30 in a direction away from the slide rail 20, and the stopper 30 is caused by the repulsive force of the elastic portion 36. The stop portion 35 can abut against the body wall 22 of the slide rail 20.

Referring to FIG. 2 and FIG. 3 together, the server 10 is moved such that the head 112 of the protruding bolt 11 enters the large end 242 of the slot 24 of the sliding rail 20, and the head 112 of the protruding bolt 11 abuts the The stopper portion 35 of the stopper 30 elastically deforms the stopper member 30 such that the stopper portion 35 of the stopper member 30 is away from the first side 222 of the slide rail 20, and the server 10 is pulled to The neck portion 111 of the boss 11 snaps into the small end 244 of the card slot 24 of the slide rail 20. At this time, the stopping portion 35 of the stopping member 30 rebounds in the direction of the first side 222 of the sliding rail 20, and the outer end edge of the stopping portion 35 of the stopping member 30 is engaged with the head of the protruding bolt 11 The latch 11 is fastened into the slot 24 of the slide rail 20 to fix the server 10 to the slide rail 20.

Referring to FIG. 4 and FIG. 5 , when the slide rail 20 needs to be separated from the server 10 , the operation portion 322 of the stopper 30 is pulled upward to deform and wrap the elastic portion 36 of the stopper 30 . The rivet 40 is pivoted upwardly, and the stopping portion 35 of the stopping member 30 is slid upward along the inclined sliding block 25, and the stopping portion 35 of the stopping member 30 is inclined away from the sliding slider 25 The direction of the rail 20 is elastically deformed until the distance between the stop portion 35 of the stop member 30 and the first side 222 of the slide rail 20 allows the head 112 of the bolt 11 to pass through. The servo 10 moves the head 112 of the bolt 10 from the small end 244 of the card slot 24 to the large end 242, thereby separating the slide rail 20 from the server 10.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. The above description is only the preferred embodiment of the present invention, and equivalent modifications or variations made by those skilled in the art will be included in the following claims.
