Description

Technical Field

[0001] The invention relates to the technical field of electric equipment guide rails, in particular to a server cabinet slide rail. Background Art

[0002] The servers in the data center are generally placed in a cabinet. The front and rear ends of the server rails are connected to the front and rear ends of the cabinet through mounting brackets. The server chassis is installed in the cabinet through the server rails, so that the chassis can be pulled out or returned from the cabinet through the rails. The existing rail mounting brackets and how to install them in the cabinet can be seen in the attached patent with publication number CN103945671A. Figure 4 , the figure only shows the mounting bracket on one side. In actual use, the slide rails and the mounting brackets are generally symmetrically installed on both sides of the server. The mounting bracket includes a guide column for inserting into the positioning hole of the cabinet rack and a locking spring plate rotatably connected to the mounting bracket. During installation, the locking spring plate is first opened, and then the guide column is inserted into the positioning hole while ensuring that the opened locking spring plate passes over the cabinet rack. Then the locking spring plate is released and reset to hook the cabinet rack under the action of the spring, so that the mounting bracket is installed on the cabinet. After the slide rails on both sides are installed in this way, the server chassis is installed on the inner rails of the slide rails on both sides. In actual operation, the distance between the slide rails on both sides is fixed after they are fixed on the rack, and it is difficult to adjust the width between the two slide rails. Summary of the invention

[0003] In order to solve the problem that it is difficult to adjust the width between the two side rails after the rail mounting bracket is installed, the present invention provides a server cabinet rail, which can still appropriately adjust the distance between the two rails after the rail mounting bracket is installed on the cabinet racks on both sides.

[0004] Its technical solution is as follows: a server cabinet slide rail, which includes a mounting bracket and a slide rail body connected to the mounting bracket. The slide rail body includes an inner rail that can be pulled out forward. The mounting bracket is used to connect to the cabinet rack and includes a bracket body, a guiding column located at the front end of the bracket body, and a locking elastic piece rotatably connected to the bracket body. A spring is also connected between the locking elastic piece and the bracket body. It is characterized in that: a bent spring piece is connected to one side of the guiding column facing away from the inner rail or facing the inner rail. The bent spring piece includes a connecting piece and an elastic piece. A connecting screw hole is opened at the front end of the guiding column, and a connecting hole is opened in the middle of the connecting piece. A connecting bolt passes through the connecting hole and is connected to the connecting screw hole. The elastic piece is V-shaped and one end of it is connected to the connecting piece. The guiding column is square, and a limiting groove is provided on one side where the bent spring piece is installed. The width of the limiting groove corresponds to the width of the bent spring piece to prevent the bent spring piece from rotating. When the bent spring piece is arranged on the side of the guiding column facing away from the inner rail, it bends and extends in the direction away from the inner rail. When the bent spring piece is arranged on the side of the guiding column facing the inner rail, it bends and extends in the direction of the inner rail.

[0005] Its further features are as follows:

[0006] When the slide rail body is a three-section rail, a guiding member is provided between its inner rail and the middle rail. The guiding member includes a connecting section located between the inner rail and the middle rail and a guiding section extending from one end of the connecting section to the front end of the middle rail. The guiding section includes an upper guiding portion located above, a lower guiding portion located below, and a connecting portion for connecting the upper guiding portion and the lower guiding portion. The upper guiding portion includes a top guiding inclined surface and a side guiding inclined surface I. One side of the top guiding inclined surface is connected to the connecting portion, and the other side extends downward to form the side guiding inclined surface I. The lower guiding portion includes a bottom guiding inclined surface and a side guiding inclined surface II. One side of the bottom guiding inclined surface is connected to the connecting portion, and the other side extends upward to form the side guiding inclined surface II. Along the direction from front to back, the top guiding inclined surface slopes downward from top to bottom, the bottom guiding inclined surface slopes upward from bottom to top, and the side guiding inclined surface I and the side guiding inclined surface II incline towards the connecting portion.

[0007] A clamping groove is opened on the middle rail, and a clamping block is provided on the guiding member. The clamping block is clamped into the clamping groove.

[0008] When the slide rail body is a two - section rail, a guiding member is provided between its outer rail and inner rail; the guiding member includes a connecting section located between the inner rail and the outer rail and a guiding section extending from one end of the connecting section to the front end of the outer rail. The guiding section includes an upper guiding part located above, a lower guiding part located below, and a connecting part for connecting the upper guiding part and the lower guiding part. The upper guiding part includes a top guiding inclined surface and a first side guiding inclined surface. One side of the top guiding inclined surface is connected to the connecting part, and the other side extends downward to form the first side guiding inclined surface; the lower guiding part includes a bottom guiding inclined surface and a second side guiding inclined surface. One side of the bottom guiding inclined surface is connected to the connecting part, and the other side extends upward to form the second side guiding inclined surface; along the front - to - rear direction, the top guiding inclined surface slopes downward from top to bottom, the bottom guiding inclined surface slopes upward from bottom to top, and the first side guiding inclined surface and the second side guiding inclined surface slope towards the connecting part.

[0009] A clamping groove is formed on the outer rail, and a clamping block is provided on the guiding member. The clamping block is clamped into the clamping groove.

[0010] The other end of the connecting section is used to abut against the ball cage.

[0011] After adopting such a structure, the slide rail can be installed on the cabinet rack through the mounting bracket by referring to the traditional way of installing the server slide rail. When installing the server chassis on the slide rail, if it is necessary to adjust the width of the two - side slide rails, the width change between the two - side slide rails can be realized by squeezing the slide rail so that its guiding column squeezes and bends the spring piece. Thus, the distance between the two slide rails can still be moderately adjusted after the slide rail is installed on the cabinet rack, which is convenient for use. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] As Figure 1The server cabinet slide rail shown includes a mounting bracket 1 and a slide rail body 2 connected to the mounting bracket 1, the slide rail body 2 includes an inner rail 21 that is pulled out forward, the mounting bracket 1 is used to connect to the cabinet rack and includes a bracket body 11, a guide column 12 located at the front end of the bracket body 11, and a locking spring piece 14 rotatably connected to the bracket body 1, a spring is also connected between the locking spring piece 14 and the bracket body 1, and a bent spring piece 13 is connected to a side of the guide column 12 that is away from the inner rail 21 or a side that is facing the inner rail 21. The figure shows the side that is away from the inner rail 21. When the bent spring piece 13 is arranged on the side of the guide column away from the inner rail 21, it bends and extends in the direction away from the inner rail, and when the bent spring piece is arranged on the side of the guide column facing the inner rail, it bends and extends in the direction of the inner rail.

[0017] The installation is similar to the traditional installation method. First, place the guide column 12 into the positioning hole on the cabinet frame and pry open the locking spring sheet 14 to make it pass over the cabinet frame. The width of the positioning hole needs to be slightly larger than the width of the guide column 12 to avoid the bending spring sheet 13 from completely shrinking. At the same time, it cannot be too large to avoid gaps that cause the slide rail to shake after installation. Then, release the locking spring sheet 14 to hook it on the cabinet frame to complete the installation of the slide rail on one side. The slide rail on the other side is symmetrically installed on the frame on the other side. When the spacing between the slide rails on both sides needs to be adjusted, when the spring sheet exists on the side away from the inner rail 21, the spacing can be expanded by squeezing the spring sheet. When the spring sheet exists on the side facing the inner rail 21, the spacing can be reduced by squeezing the spring sheet. In actual use, it is generally installed on the side away from the inner rail.

[0018] Specifically, Figure 1 Combination Figure 2 The bent spring sheet 13 shown includes a connecting sheet 131 and an elastic sheet 132. A connecting screw hole is provided at the front end of the guide column 12, and a connecting hole 133 is provided in the middle of the connecting sheet 131. The connecting bolt 15 passes through the connecting hole 133 and is connected to the connecting screw hole. The elastic sheet 132 is V-shaped and one end thereof is connected to the connecting sheet 131 and can be integrally formed. Its bending angle faces forward to facilitate the guide column to be inserted into the frame. The guide column 12 is square, and a limiting groove is provided on one side of the guide column 12 where the bent spring sheet 13 is installed. The width of the limiting groove corresponds to the width of the bent spring sheet 13 to prevent the bent spring sheet from rotating.

[0019] in addition, Figure 1 Combination Figure 3As shown in the figure, the slide rail body in the figure is a two-section rail. A guiding member 23 is provided between its outer rail 22 and inner rail 21, and it can be a colloid, an injection molded part, etc.; the guiding member 23 includes a connecting section 231 located between the inner rail 21 and the outer rail 22 and a guiding section 232 extending from one end of the connecting section 231 to the front end of the outer rail. The guiding section 232 includes an upper guiding part located above, a lower guiding part located below, and a connecting part 233 for connecting the upper guiding part and the lower guiding part. The upper guiding part includes a top guiding inclined surface 234 and a first side guiding inclined surface 235. One side of the top guiding inclined surface is connected to the connecting part 233, and the other side extends downward to form the first side guiding inclined surface 235; the lower guiding part includes a bottom guiding inclined surface 236 and a second side guiding inclined surface 237. One side of the bottom guiding inclined surface 236 is connected to the connecting part 233, and the other side extends upward to form the second side guiding inclined surface 237; along the front-to-back direction, the top guiding inclined surface 234 slopes downward from top to bottom, the bottom guiding inclined surface 236 slopes upward from bottom to top, and the first side guiding inclined surface 235 and the second side guiding inclined surface 237 are inclined toward the connecting part. The inner rail 21 is effectively guided by the guiding inclined surfaces to facilitate its insertion into the outer rail 22.

[0020] Meanwhile, in combination with Figure 4 , a card slot 221 is formed on the outer rail 22, and a card block 238 is provided on the guiding member 23. The card block 238 is snapped into the card slot 221 to fix it on the outer rail.

[0021] The above-mentioned guiding member is also applicable to a three-section rail. When the slide rail body is a three-section rail, a guiding member is provided between its inner rail and middle rail; the guiding member includes a connecting section located between the inner rail and the middle rail and a guiding section extending from one end of the connecting section to the front end of the middle rail. The remaining structure of the guiding member is similar to that of the guiding member of the above two-section rail. Similarly, a card slot is formed on the middle rail, and a card block is provided on the guiding member. The card block is snapped into the card slot for fixation; in addition, the other end of the connecting section 231 is used to abut against the ball cage 24, which can limit the ball cage 24 between the inner rail and the outer rail / middle rail to prevent the cage from being taken out when the inner rail is pulled out.

[0022] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those familiar with the technology within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
