Slide rail fixing device

The present invention relates to a 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, and generally 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, and the slide rail is provided with a mounting groove for receiving the protruding bolt of the server, and the slide rail is fixed The device includes a resilient positioning member and an unlocking member, the first end of the positioning member is fixed to the sliding rail, and the unlocking member is rotatably assembled to the second end of the positioning member, and the positioning member is provided with a The protruding bolt is blocked to the latch body of the mounting slot, and the sliding is fixed When the servo is in the server, the latching bolt of the server is received in the mounting slot of the server, and the latching body of the positioning component blocks the latching bolt in the mounting slot, so that the sliding rail is fixed to the server. When the slide rail is disassembled, the unlocking member is rotated, and one side of the unlocking member abuts the slide rail to move the second end of the positioning member away from the server, thereby moving the latch body of the positioning member away from the The slide rail separates the latch body from the boss.

Compared with the prior art, the rail fixing device fixes the protruding bolt of the server by using the positioning member, and separates the positioning member from the protruding bolt by rotating the unlocking member mounted on the positioning member, thereby The loading and unloading process of the server relative to the slide rail is convenient and fast.

Referring to FIG. 1, a preferred embodiment of the slide rail fixing device of the present invention is used to fix a slide rail 20 to a servo 10. The slide rail fixing device includes a positioning member 30 and an unlocking member 40.

The side of the server 10 is provided with a protruding bolt 11 which forms a neck and a head having a size larger than the neck.

The slide rail 20 is provided with a J-shaped mounting groove 21, and the mounting groove 21 includes a guiding portion 211 perpendicular to the sliding direction of the sliding rail 20 and a fixing portion 213 parallel to the sliding direction of the sliding rail 20. A side surface of the slide rail 20 protrudes from the mounting groove 21 to form a plurality of connecting portions 23 . The end of the slide rail 20 is formed with a projection 25, and the projection 25 forms an inclined surface toward a side of the mounting groove 21.

The positioning member 30 is a long elastic body. The first end is provided with a plurality of connecting holes 34. The second end of the positioning member 30 has a pivoting portion 32 and a shoulder is formed adjacent to the two ends of the pivoting portion 32. a portion 33, the pivoting portion 32 is provided with a pivot Hole 322. The positioning member 30 is provided with a first avoiding hole 36 and a second avoiding hole 38 adjacent to the pivoting portion 32 thereof. A latch body 39 is obliquely outwardly inclined at an edge of the first avoidance hole 36.

The unlocking member 40 is formed by bending a wire and is substantially rectangular, and has a top portion 41 formed on one side thereof, and an operating portion 43 is formed on a side opposite to the abutting portion 41. The unlocking member 40 further includes a pair of connecting portions. The arm portion 45 at one end of the operating portion 43 and the other arm portion 47 extending perpendicularly from the other end of the operating portion 43 extend from the free end of the arm portion 47 to a central portion of the rectangle to form a pivot 49.

Referring to FIG. 2 and FIG. 3 together, the pivoting member 49 of the unlocking member 40 is inserted into the pivot hole 322 of the positioning member 30, so that the unlocking member 40 is rotatably mounted to the second positioning member 30. The connecting hole 34 of the positioning member 30 is sleeved on the corresponding connecting portion 23 of the sliding rail 20 and fixed to fix the first end of the positioning member 30 to the sliding rail 20. The first escaping hole 36 of the positioning member 30 is facing the fixing portion 213 of the mounting groove 21, the latching body 39 of the positioning member 30 is facing the guiding portion 211 of the mounting groove 21, and the abutting portion 41 of the unlocking member 40 Abutting against the inclined surface of the projection 25 of the slide rail 20, the operating portion 43 of the unlocking member 40 is facing the second avoiding hole 38 of the positioning member 30 to facilitate the operation.

The servo 10 is moved such that the neck of the boss 11 slides downward from the guiding portion 211 of the mounting groove 21 of the sliding rail 20 and then slides horizontally into the fixing portion 213 of the mounting groove 21, thereby loading the sliding rail 20 It is provided in the server 10. When the protruding bolt 11 of the servo 10 slides downward in the guiding portion 211 of the mounting groove 21, the head of the protruding bolt 11 is deformed in a direction away from the sliding rail 20 by the latching body 39 of the positioning member 30. , the protruding bolt 11 is slid into the fixing portion 213 of the mounting groove 21 and protrudes into the first avoiding hole 36 of the positioning member 30; When the latch 11 is slid into the fixing portion 213, the head of the latch 11 is no longer pushed against the latch body 39, and the positioning member 30 is deformed. The latching body 39 of the positioning member 30 blocks the latch 11 The head portion fixes the boss 11 of the server 10 in the mounting groove 21 of the positioning member 30 to fix the slide rail 20 to the server 10.

Referring to FIG. 4 and FIG. 5 , when the slide rail 20 needs to be separated from the server 10 , the operating portion 43 of the unlocking member 40 is pulled away from the servo 10 to rotate the unlocking member 40 . The abutting top portion 41 of the 40 slides along the inclined surface of the protrusion 25 of the sliding rail 20 to abut the sliding rail 20, so that the second end of the positioning member 30 is elastically deformed away from the sliding rail 20, so that the card is folded. The body 39 is separated from the boss 11; the unlocking member 40 is further rotated until the arms 45 and 47 abut against the corresponding shoulders 33 of the positioning member 30. At this time, the plane of the unlocking member 40 and the sliding rail 20 are The side surface is at an angle of less than 90 degrees, so that the positioning member 30 is in a stable unlocked state, and the servo 10 can be conveniently moved to slide the bolt 11 horizontally out of the fixing portion of the mounting groove 21 of the sliding rail 20. 213, and then slides out the guiding portion 211 of the mounting groove 21, thereby separating the sliding 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.
