Description

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 servo. The side of the servo rail is provided with a protruding bolt. The slide rail includes a main body wall, and the main body wall defines a card slot for receiving the protruding bolt. The rail fixing device includes a stopping member, the stopping member includes a main body portion extending from one end of the main body portion and bent away from the sliding rail An operating portion, a stopping portion extending from the other end of the main body portion, and a fixing portion extending from the operating portion toward the sliding rail direction, wherein the fixing portion of the stopper is fixed to the sliding rail and the stopping portion The main body of the member is in close contact with the main body wall of the slide rail. The latch of the servo is received in the slot of the slide rail, and the stop portion of the stop member blocks the latch bolt in the slot, so that the slide rail Fixed to the server, the operating portion pressing the stopper causes the main body portion of the stopper to be elastically deformed away from the sliding rail, and the stopping portion of the stopping member is disengaged from the protruding bolt, and moves The servo causes the bolt to escape 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 press the operating portion of the stopping member to make the stopper The stopping portion is disengaged from the protruding bolt, so that the loading and unloading process of the servo relative to the sliding rail is convenient and quick.

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

Figures 2-4 are perspective assembled views of the components shown in Figure 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 side edges of the main body wall 22 respectively extend toward the first side 222 thereof to form a folded edge 23. The main body wall 22 defines a J-shaped card slot 24 from a folded edge 23 toward the middle of the main body wall 22 adjacent to one end thereof. The card slot 24 includes an entrance 242 perpendicular to the sliding direction of the slide rail 20 and parallel to the slide rail 20 . a fixing portion 244 in the sliding direction. The main body wall 22 defines a fixing hole 26 near the card slot 24 .

The stopper member 30 is integrally formed by an elastic metal piece, and the peripheral edge of the elastic metal piece is obliquely bent toward the same side to form a U-shaped inclined flange 31. The stopper 30 includes a main body portion 32. One end of the main body portion 32 is bent away from the slide rail 20 to form an operation portion 33. An end of the operating portion 33 remote from the main body portion 32 extends in a direction close to the sliding rail 20 to form an elongated fixing portion 34. In the present embodiment, the fixing portion 34 is attached to the operating portion 33 of the stopper 30. A tab formed by a U-shaped groove is formed on the side. The end of the fixing portion 34 is located on the same plane as the main body portion 32, and a through hole 342 is defined in the same. The stopper 30 defines a through hole 35 at the other end of the main body portion 32. A side wall of the through hole 35 adjacent to the main body portion 32 forms a stopper portion 352.

Referring to FIG. 2 , the rivet 40 is inserted into the through hole 342 of the stopper 30 and fixed to the fixing hole 26 of the sliding rail 20 , and the stopper 30 is fixed to the sliding rail 20 . The main body portion 32 of the stopper 30 is abutted against the main body wall 22 of the slide rail 20, and the inclined flange 31 of the stopper member 30 is opposite to the inlet 242 of the slot 24 of the slide rail 20, the stopper The through hole 35 of the 30 is opposite to the fixing portion 244 of the card slot 24 of the slide rail 20.

Referring to FIG. 3, the server 10 is moved so that the head 112 of the latch 11 enters the slot 24 of the slide rail 20 from the opening 242 of the slide rail 20. In the process, the latch 11 The head portion 112 abuts against the body portion 32 of the stop member 30 and is elastically deformed away from the first side 222 of the slide rail 20. An inclined flange 31 at the periphery of the stopper 30 is used for the The head 112 of the bolt 11 is guided to slide the head 112 of the bolt 11 along the inclined flange 31 of the stopper 30 to facilitate pushing the stopper away from the first side 222 of the rail 20 The body portion 32 of the 30 is elastically deformed. The servo 10 is pulled, and the neck portion 111 of the boss 11 is engaged with the fixing portion 244 of the card slot 24 of the slide rail 20. At this time, the head 112 of the bolt 11 is opposite to the through hole 35 of the stopper 30, and the main body portion 32 of the stopper 30 rebounds toward the first side 222 of the slide rail 20, and the bolt 11 is The head 112 is received in the through hole 35 of the stopper 30. The stopper 352 of the stopper 30 is engaged with the head 112 of the bolt 11 to clamp the latch 11 to the card of the slide rail 20. The fixing portion 244 of the groove 24 further fixes the servo 10 to the slide rail 20 as shown in FIG.

Referring to FIG. 4 together, when the slide rail 20 needs to be separated from the servo 10, the operation portion 33 of the stopper 30 is pressed to attach the operation portion 33 to the first side 222 of the slide rail 20, so that The main body portion 32 of the stopping member 30 is elastically deformed away from the first side 222 of the sliding rail 20 until the stopping portion 352 of the stopping member 30 is disengaged from the head portion 112 of the protruding bolt 11 . The servo 10 can be moved to remove the head 112 of the bolt 10 from the card slot 24, thereby separating the slide rail 20 from the servo 10.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law.
