Description

Technical Field

[0001] The utility model relates to the technical field of slide rails, in particular to a slide rail structure for a server. Background Art

[0002] A slide rail is a device used to support and guide the movement of an object, and plays an important role in sliding support in various servo sliding modules.

[0003] A server slide rail structure disclosed in the patent with the publication number CN219981347U includes an outer rail and an inner rail that moves along its length direction inside the outer rail. A chute is provided inside the outer rail, and side grooves are provided on the inner walls of the vertical ends on both sides of the chute. An elastic support assembly that contacts the bottom of the inner rail is suspended on the inner walls of the vertical ends of the side grooves. The elastic support assembly includes a flat support plate and a smooth arc-shaped plate. In the utility model, through the suspended elastic support assembly, when the server slides and exerts a large pressure on the inner rail, the inner rail can squeeze the elastic support assembly downward, squeezing the arc-shaped part of the elastic support assembly downward to cause it to deform, which can play an elastic buffering role for the inner rail, thereby avoiding the phenomenon that the inner rail bulges locally under the action of a large pressure and cannot slide in the outer rail, effectively improving the sliding flexibility of the slide rail. However, in actual use, the elastic support assembly has an up-and-down undulating phenomenon, which is likely to cause poor sliding smoothness.

[0004] Therefore, it is necessary to provide a new server slide rail structure to solve the above technical problems. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a server slide rail structure with smoother sliding.

[0007] Limiting slide rods, there are two groups, and the two groups of limiting slide rods are respectively installed in the semi-circular arc grooves on both sides of the chute. Limiting clamping plates are inserted at both ends of the two groups of limiting slide rods, and the limiting clamping plates are detachably installed at one end of the outer rail through screws. A plurality of dovetail grooves are evenly opened on the outer sides of the two groups of limiting slide rods, and graphite slide bars are inserted in each of the plurality of dovetail grooves;

[0008] An inner rail is slidably installed in the chute, grooves that are slidably matched with the limiting slide rods are opened on both sides of the inner rail, and a supporting and sliding assembly is installed on the inner rail.

[0009] Preferably, the limiting clamping plate is provided with a counterbore that is inserted and matched with the limiting slide rod.

[0010] Preferably, a plug rod inserted and matched with the limit slide rod is installed in the counterbore, and jacks inserted and matched with the plug rod are opened at both ends of the limit slide rod.

[0011] Preferably, the support and slide assembly includes a threaded tube. There are two threaded tubes, and the two threaded tubes are symmetrically installed on the inner rail. A support rod is threadedly installed on the two threaded tubes. A first ball is installed at the bottom end of the support rod through the threaded tube, and a first arc groove slidably matched with the first ball is opened at the bottom end of the chute.

[0012] Preferably, second balls are embedded on both sides of the top end of the inner rail, and a second arc groove slidably matched with the second balls is opened at the top end of the outer rail.

[0013] Compared with the related art, the server slide rail structure provided by the present utility model has the following beneficial effects:

[0014] 1. The present utility model provides a server slide rail structure.

It should be understood that the specific embodiments described herein are only used to explain the present utility model, and are not used to limit the present utility model.

[0024] The following describes in detail the specific implementation of the present utility model with reference to specific embodiments.

[0025] Please refer to Figures 1 to 6 , a server slide rail structure provided by an embodiment of the present utility model, the server slide rail structure includes:

[0026] An outer rail 1, the outer rail 1 is provided with a chute 101, and semi-circular grooves 102 are symmetrically provided on both sides of the chute 101;

[0027] Two limit slide bars 2, and the two limit slide bars 2 are respectively installed in the semi-circular grooves 102 on both sides of the chute 101, and limit clamping plates 4 are inserted at both ends of the two limit slide bars 2, and the limit clamping plates 4 are detachably installed at one end of the outer rail 1 by screws. A plurality of dovetail grooves 201 are evenly provided on the outer sides of the two limit slide bars 2, and graphite slide bars 21 are inserted in the plurality of dovetail grooves 201;

[0028] An inner rail 3, which is slidably installed in the chute 101, and grooves 301 that are slidably matched with the limit slide bars 2 are provided on both sides of the inner rail 3, and a support and slide assembly 5 is installed on the inner rail 3.

[0029] It should be noted that: during use, when the inner rail 3 slides along the chute 101 of the outer rail 1, the grooves 301 on both sides thereof slide synchronously on the limit slide bars 2, and the graphite slide bars 21 inserted on the limit slide bars 2 slide synchronously with the grooves 301, so as to utilize the wear-resistant and lubricating characteristics of graphite to make the inner rail 3 slide more smoothly. The support and slide assembly 5 is further provided to increase the support strength of the inner rail 3, so as to facilitate better carrying of heavy objects and sliding along the outer rail 1.

[0030] In an embodiment of the present utility model, please refer to Figure 1 , Figure 3 and Figure 4, the limit clamping plate 4 is provided with a counterbore 401 which is inserted and matched with the limit sliding rod 2. An inserting rod 41 which is inserted and matched with the limit sliding rod 2 is installed in the counterbore 401. Both ends of the limit sliding rod 2 are provided with inserting holes 202 which are inserted and matched with the inserting rod 41;

[0031] It should be noted that: after the two limit sliding rods 2 are stuck in the semi-circular arc grooves 102, the limit clamping plate 4 is inserted into the inserting holes 202 opened on the limit sliding rods 2 by using the inserting rod 41, and then the limit clamping plate 4 is installed on the outer rail 1 by using screws, so as to fix the two limit sliding rods 2 in the semi-circular arc grooves 102. The graphite sliding strip 21 on the limit sliding rod 2 is wrapped and limited by using the counterbore 401 to prevent it from sliding out. When the graphite sliding strip 21 needs to be replaced, the limit clamping plate 4 can be disassembled from the outer rail 1.

[0032] In the embodiment of the present utility model, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 , the supporting and sliding assembly 5 includes threaded pipes 51. There are two threaded pipes 51, and the two threaded pipes 51 are symmetrically installed on the inner rail 3. A support rod 52 is threadedly installed on the two threaded pipes 51. A first ball 53 is installed at the bottom end of the support rod 52 after passing through the threaded pipe 51. An arc groove one 103 which is slidably matched with the first ball 53 is opened at the bottom end of the sliding groove 101;

[0033] Two second balls 31 are embedded on both sides of the top end of the inner rail 3. An arc groove two 104 which is slidably matched with the second ball 31 is opened at the top end of the outer rail 1.

[0034] It should be noted that: when the supporting and sliding assembly 5 is used, by screwing the support rod 52, the first ball 53 at the bottom end of the support rod 52 contacts the arc groove one 103, so as to further support the inner rail 3. While strengthening the support by using the first ball 53, it will not affect its normal sliding. The second balls 31 are similarly arranged on both sides of the inner rail 3 to further strengthen the support strength of the inner rail 3.

[0035] The working principle of the server slide rail structure provided by the present utility model is as follows:

[0036] During use, when the inner rail 3 slides along the chute 101 of the outer rail 1, the grooves 301 on both sides thereof slide synchronously on the limit slide bar 2. A graphite slide bar 21 is inserted on the limit slide bar 2 and slides synchronously with the groove 301. Thus, by utilizing the wear-resistant and lubricating characteristics of graphite, the inner rail 3 slides more smoothly. Then, a support and slide assembly 5 is provided to increase the support strength of the inner rail 3, facilitating better carrying of heavy objects and sliding along the outer rail 1. When the support and slide assembly 5 is in use, by turning the support rod 52, the ball one 53 at the bottom end of the support rod 52 contacts the arc groove one 103, thereby realizing further support for the inner rail 3. While using the ball one 53 to strengthen the support, it does not affect its normal sliding. Similarly, balls two 31 are provided on both sides of the inner rail 3 to further enhance the support strength of the inner rail 3;

[0037] Further, after the two limit slide bars 2 are stuck in the semi-circular arc grooves 102, the limit clamping plate 4 is inserted into the jacks 202 opened on the limit slide bars 2 by means of the insertion rods 41, and then the limit clamping plate 4 is installed on the outer rail 1 by means of screws, realizing the fixation of the two limit slide bars 2 in the semi-circular arc grooves 102. The graphite slide bar 21 on the limit slide bar 2 is wrapped and limited by the counterbore 401 to prevent it from sliding out. When the graphite slide bar 21 needs to be replaced, the limit clamping plate 4 is removed from the outer rail 1, which is convenient for later disassembly and replacement.

[0038] The circuits and controls involved in the present utility model are all prior arts and will not be elaborated herein.

[0039] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included in the patent protection scope of the present utility model.
