Description

Technical Field

[0001] This utility model belongs to the field of computer equipment assembly technology, and specifically relates to a retractable assembly component for computer equipment guide rails. Background Technology

[0002] When installing computer equipment (such as servers and switches), it is necessary to use guide rail components to cooperate with the cabinet to achieve pull-out assembly, so as to facilitate later maintenance.

[0003] CN202444722U describes an adjustable-depth rack rail. This component can adjust the installation depth of the entire rail within a certain range. However, this component does not have a pre-mounting function and requires screws to be fixed before the equipment can be placed. This will occupy the space where the server screws are fixed, making installation inconvenient and not universal.

[0004] US6578939B1 discloses a telescopic rail assembly that achieves length adjustment through the nesting of inner and outer rails, and uses positioning holes and elastic pins to fix the telescopic position, adapting to racks of a certain depth. However, the overall installation process of this assembly is cumbersome, its hooks only emphasize "removability" to adapt to width, resulting in poor suspension stability during installation, and the fixation relies solely on screws, lacking a secure fixation guarantee.

[0005] This application has a pre-attachment function, and during pre-attachment, it can automatically fit and clamp the cabinet beam, providing good anti-detachment effect and easy installation. Utility Model Content

[0006] The purpose of this invention is to provide a retractable assembly for computer equipment guide rails to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0008] A retractable guide rail assembly for computer equipment includes:

[0009] The L-shaped support plate includes an integrally formed base plate and a side plate; the upper end of the side plate opposite to the base plate has an integrally formed U-shaped wide groove, and the lower end has an integrally formed U-shaped narrow groove; four limiting holes are spaced apart along the length of one side of the side plate.

[0010] The telescopic plate is slidably assembled in the U-shaped wide groove and U-shaped narrow groove of the side plate. The upper end of the telescopic plate is integrally formed with a U-shaped limiting block embedded in the U-shaped wide groove to limit the lateral displacement of the telescopic plate. The telescopic plate has a sliding groove extending along its own length in the middle. The sliding groove is provided with a semi-hollow rivet that passes through the limiting hole and is used to limit the sliding stroke of the telescopic plate.

[0011] Fixed pre-mounted plate and movable pre-mounted plate, the fixed pre-mounted plate and the movable pre-mounted plate are symmetrically arranged and have the same structure, both are L-shaped and the bending direction is opposite to the width direction of the bottom plate. The fixed pre-mounted plate is integrally formed on one end of the side plate and is pre-mounted on the computer cabinet. The movable pre-mounted plate is integrally formed on the end of the telescopic plate opposite to the fixed pre-mounted plate and is pre-mounted on the computer cabinet after telescopic movement.

[0012] Both the fixed pre-hanging plate and the movable pre-hanging plate have an L-shaped groove in the middle, and screw holes are symmetrically opened on both sides of the L-shaped groove. Both have a pre-hanging hook integrally formed towards the inner wall of the L-shaped groove. The bending direction of the pre-hanging hook is vertically downward, and a spring plate mounting seat is integrally formed at the bending point. A miniature spring plate is fixedly assembled in the spring plate mounting seat. The elasticity of the miniature spring plate ensures that the bending point of the pre-hanging hook always has a pre-tightening force towards the inner wall of the corresponding pre-hanging plate. During pre-hanging, it can automatically fit and lock into the crossbeam of the cabinet frame. The contact end of the pre-hanging hook is provided with anti-slip teeth.

[0013] Optionally, the portion of the semi-hollow rivet located within the sliding groove is fitted with an annular wear-resistant pad to reduce frictional loss during the sliding process.

[0014] Optionally, the length of the pre-hook is 12.5mm, and the length of its vertical bend is 3.5mm.

[0015] Optionally, the base plate has a length of 470mm and a width of 69mm; the fixed pre-hanging plate has a height of 43mm and a width of 19mm.

[0016] Optionally, the minimum center-to-center distance between the fixed pre-mounted plate and the movable pre-mounted plate is 530mm when the telescopic plate is in the retracted state, and the center-to-center distance is 812mm when the telescopic plate is in the maximum extended state.

[0017] Optionally, the L-shaped support plate is made of 1.5mm thick cold-rolled steel plate Q235A, and the telescopic plate is made of 2.0mm thick cold-rolled steel plate Q235A.

[0018] Optionally, the clearance between the U-shaped limiting block and the wide U-shaped groove is ≤0.5mm, and the clearance between the telescopic plate and the narrow U-shaped groove is ≤0.8mm, to improve sliding stability.

[0019] Optionally, the surfaces of both the L-shaped support plate and the telescopic plate are treated with black electrophoresis to improve rust prevention and surface wear resistance.

[0020] This utility model has the following beneficial effects:

[0021] 1. Wide adaptability: The distance between the fixed pre-mounted plate and the movable pre-mounted plate can be adjusted within the range of 530-812mm, which is compatible with various depth specifications of cabinets. There is no need to replace different models of guide rails, and the versatility is significantly improved.

[0022] 2. Stable and reliable sliding: The dual-rail guide with U-shaped wide groove and U-shaped narrow groove, combined with U-shaped limit block and small gap design, reduces lateral offset, ensures smooth sliding without jamming, and improves the operating feel;

[0023] 3. Pre-attached for high efficiency and secure fastening: The pre-attached hooks, combined with miniature spring plates, can automatically fit and lock onto the cabinet beams. Anti-slip teeth enhance friction and prevent loosening. Pre-attached positioning is quick and convenient, and it has strong stability under vibration.

[0024] 4. High durability: The ring-shaped wear-resistant pad reduces sliding friction loss. The cold-rolled steel plate material combined with black electrophoretic treatment provides excellent rust prevention and wear resistance, extending the service life of the component.

[0025] 5. Easy installation: The one-piece molded structure reduces scattered parts, and the dual fixing method of pre-hanging + bolt fastening allows a single person to complete the assembly. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses a retractable assembly for a guide rail of a computer device, including an L-shaped support plate 1, a telescopic plate 2, a fixed pre-mounted plate 3, and a movable pre-mounted plate 4.

[0034] The L-shaped support plate 1 includes an integrally formed base plate 11 and side plates 12, made of 1.5mm thick cold-rolled steel plate Q235A with a black electrophoretic coating, which provides both good rust resistance and surface wear resistance. The base plate 11 is 470mm long and 69mm wide, providing a stable support surface for computer equipment. The upper end of the side plate 12, opposite to the base plate 11, has an integrally formed U-shaped wide groove 13, and the lower end has an integrally formed U-shaped narrow groove 14, forming a double-rail sliding guide structure to provide a precise sliding trajectory for the telescopic plate 2. Four limiting holes 15 are spaced apart along the length of one side of the side plate 12 to limit the telescopic stroke of the components.

[0035] The telescopic plate 2 is made of 2.0mm thick cold-rolled steel plate Q235A, and its surface is also treated with black electrophoresis. It is slidably assembled in the U-shaped wide groove 13 and U-shaped narrow groove 14 of the side plate 12. A U-shaped limiting block 21 is integrally formed at the upper end of the telescopic plate 2. The U-shaped limiting block 21 is embedded in the U-shaped wide groove 13, and the fit clearance between the telescopic plate 2 and the U-shaped wide groove 13 is ≤0.5mm. At the same time, the fit clearance between the telescopic plate 2 and the U-shaped narrow groove 14 is ≤0.8mm. The double limiting design effectively restricts the lateral displacement of the telescopic plate 2 during sliding and ensures sliding stability. A sliding groove 22 extending along its own length is opened in the middle of the telescopic plate 2. A semi-hollow rivet 23 is provided in the sliding groove 22. The semi-hollow rivet 23 passes through the limiting hole 15 on the side plate 12, which does not affect the sliding of the telescopic plate 2, but can limit its sliding stroke. The part of the semi-hollow rivet 23 located in the sliding groove 22 is fitted with an annular wear-resistant pad, which can reduce friction loss during sliding and extend the service life of the component.

[0036] The fixed pre-mounted plate 3 and the movable pre-mounted plate 4 are symmetrically arranged and have the same structure, both being L-shaped with a bending direction opposite to the width direction of the base plate 11. The fixed pre-mounted plate 3 is integrally formed on one end of the side plate 12 and is used for pre-mounting and fixing to the computer rack; the movable pre-mounted plate 4 is integrally formed on the end of the telescopic plate 2 opposite to the fixed pre-mounted plate 3, and can be pre-mounted in the rack after telescopically moving with the telescopic plate 2, achieving adaptation to racks of different depths. In this embodiment, the limiting hole 15 is provided on the side plate near the movable pre-mounted plate 4.

[0037] Both the fixed pre-hanging plate 3 and the movable pre-hanging plate 4 have L-shaped grooves 31 in the middle, and screw holes 32 are symmetrically provided on both sides of the L-shaped grooves 31 for further tightening after pre-hanging. Both have pre-hanging hooks 33 integrally formed, facing the inner wall of their own L-shaped grooves 31. The bending direction of the pre-hanging hooks 33 is vertically downward, with a total length of 12.5mm, of which the length of the vertical bending section is 3.5mm. A spring plate mounting seat is integrally formed at the bending point of the pre-hanging hooks 33. The spring plate mounting seat contains a 0.3mm thick stainless steel miniature spring plate 34. The elasticity of the miniature spring plate 34 ensures that the bending point of the pre-hanging hooks 33 always has a pre-tightening force facing the inner wall of the corresponding pre-hanging plate, so that it can automatically fit and lock into the crossbeam of the cabinet frame during pre-hanging. The contact end of the pre-hanging hooks 33 has three anti-slip teeth 35 with a tooth height of 0.8mm to further enhance the friction after pre-hanging and prevent vibration from loosening. The fixed pre-mounted plate 3 has a height of 43mm and a width of 19mm. Its minimum center distance with the movable pre-mounted plate 4 when the telescopic plate 2 is in the retracted state is 530mm, and its center distance when the telescopic plate 2 is in the extended state is 812mm, which can adapt to the needs of cabinets of different depths.

[0038] It should be noted that unspecified tolerances shall conform to GB1804 Grade M, and unspecified tolerances for welded structures shall conform to GB19804 Grade A. Sharp edges shall be deburred.

[0039] Assembly and use process: 1. Fixed end pre-hanging: Align the L-shaped groove 31 of the fixed pre-hanging plate 3 with the crossbeam on one side of the cabinet. The pre-hanging hook 33 automatically attaches to the crossbeam and is locked under the pre-tightening force of the micro spring plate 34. The anti-slip teeth 35 bite the surface of the crossbeam to prevent slippage.

[0040] 2. Telescopic adjustment: According to the depth of the rack, pull the telescopic plate 2 along the U-shaped wide groove 13 and U-shaped narrow groove 14 until the pre-mounted plate 44 reaches the position of the crossbeam on the other side of the rack;

[0041] 3. Pre-hanging on the mobile end: Align the pre-hanging hook 33 of the mobile pre-hanging plate 4 with the crossbeam of the cabinet on the other side, and it will automatically lock in place under the action of the spring sheet;

[0042] 4. Fastening and reinforcement: By screwing in bolts through the screw holes 32 of the fixed pre-mounted plate 3 and the movable pre-mounted plate 4, the components are firmly fixed to the cabinet;

[0043] 5. Equipment installation: The computer equipment can be fixed to the component through the mounting holes on the base plate 11, which enables the equipment to be installed and maintained by pulling out.

[0044] Actual testing shows that this component can stably adapt to cabinets with a depth of 600-900mm, and the wear after 1000 sliding cycles is ≤0.1mm. It can withstand 24 hours of continuous vibration in a 5-50Hz environment without loosening or shifting. Installing a single set of components only takes 2-3 minutes, fully meeting the efficiency and stability requirements of computer equipment cabinet assembly.

[0045] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
