Description

TECHNICAL FIELD

[0001] The present invention relates to a slide rail, in particular to a tool-free quick-mount slide rail. BACKGROUND

[0002] A conventional tool-free quick-mount slide rail for a server rack includes a bracket and two multi-stage cylindrical joints arranged on the bracket. The two multi-stage cylindrical joints are arranged in two holes of the bracket. Each of the multi-stage cylindrical joints has a plurality of cylindrical segments with a gradually decreasing diameter from back to front. The cylindrical segments with different diameters are capable of being inserted into the holes with different sizes. However, when the tool-free quick-mount slide rail is applied to a server rack with small holes, the cylindrical segments at the front ends of the two multi-stage cylindrical joints are inserted into the holes. In this case, the server rack and the tool-free quick-mount slide rail form an excessively long force arm, which easily leads to poor stability between the server rack and the tool-free quick-mount slide rail, or even insufficient assembly strength to support the weight of the server. SUMMARY

[0003] One object of the present invention is to provide a tool-free quick-mount slide rail that can improve at least one problem in the prior art.

[0004] In some embodiments, the tool-free quick-mount slide rail of the present invention is suitable for being arranged on a rack. The rack has a plate body and a plurality of holes formed on the plate body. The tool-free quick-mount slide rail includes a bracket and a joint sliding module. The bracket has side plates extending in a front-rear direction and an up-down direction, and a front plate extending from the front edges of the side plates in a left-right direction and capable of abutting against the plate body of the rack. The front plate has two through holes arranged in the up-down direction. The joint sliding module is arranged on the bracket and is capable of moving in the front-rear direction relative to the side plates between a plurality of locking positions. The joint sliding module includes a joint sliding block having a block body and two multi-stage cylindrical joints extending forward from the block body and capable of respectively passing through the two through holes of the front plate. Each of the multi-stage cylindrical joints has a plurality of cylindrical segments with a gradually decreasing diameter from back to front. When the joint sliding module is in any one of the locking positions, one of the cylindrical segments of each of the multi-stage cylindrical joints protrudes forward from the front plate by at least a predetermined distance to be inserted into a hole of the plate body.

[0005] In some embodiments, the bracket further has two positioning plates extending from the side plates in the left-right direction and positioned above and below the block of the joint sliding block, respectively, each of the positioning plates having a curved positioning slot with a plurality of positioning slot portions, the block of the joint sliding block having a sliding slot extending in the up-down direction and in the left-right direction, the joint sliding module further comprising a positioning rod extending in the up-down direction and slidably disposed in the sliding slot in the left-right direction, both ends of the positioning rod being slidably disposed in the positioning slots of the two positioning plates, when the joint sliding module is in any one of the locking positions, the positioning rod is positioned in one of the positioning slot portions of the positioning slots of the two positioning plates, and the two positioning plates abut against the positioning rod from behind.

[0006] In some embodiments, the joint sliding module further comprises at least one positioning elastic member disposed in the sliding slot, the positioning elastic member being configured to push the positioning rod in the left-right direction to position the positioning rod in each of the positioning slot portions of the positioning slots.

[0007] In some embodiments, the side plates of the bracket have at least one guide slot extending in the front-back direction, and the joint sliding block further has at least one guide column protruding from the block and slidably disposed in the at least one guide slot in the front-back direction.

[0008] In some embodiments, the joint sliding module further comprises two sliding sleeve cylindrical joints slidably sleeved on the two multi-stage cylindrical joints, respectively, and two first elastic members interposed between the two sliding sleeve cylindrical joints and the block of the joint sliding block, each of the sliding sleeve cylindrical joints having a cylindrical joint portion and a first abutting portion located behind the cylindrical joint portion, the two first elastic members driving the two sliding sleeve cylindrical joints to move forward so that the first abutting portions of the two sliding sleeve cylindrical joints abut against the rear side surface of the front plate from the front, and the cylindrical joint portions of the two sliding sleeve cylindrical joints protrude from the two through holes by at least the preset distance, respectively.

[0009] In some embodiments, the joint sliding module further comprises two sliding sleeve square column joints slidably sleeved on the two multi-stage cylindrical joints, respectively, and two second elastic members interposed between the two sliding sleeve square column joints and the block of the joint sliding block, each of the sliding sleeve square column joints having a square column joint portion and a second abutting portion located behind the square column joint portion, the two second elastic members driving the two sliding sleeve square column joints to move forward so that the second abutting portions of the two sliding sleeve square column joints abut against the rear side surface of the front plate from the front, and the square column joint portions of the two sliding sleeve square column joints protrude from the two through holes by at least the preset distance, respectively.

[0010] The joint sliding module of the present invention is capable of moving between multiple locking positions relative to the side panels along the front-to-back direction. This allows the positions of the two multi-step cylindrical joints of the joint sliding module to be adjusted in the front-to-back direction, so that each cylindrical segment of each multi-step cylindrical joint can protrude forward from the front panel of the rack body by at least a predetermined distance to be inserted into the mounting hole of the rack body. This prevents an excessively long moment arm from forming between the rack and the tool-less quick-release rails, and improves the stability of the assembly between the rack and the tool-less quick-release rails.

[0020] See Figures 1 to 4 An embodiment of the tool-free quick-install slide rail 100 of the present invention is suitable for being installed on a rack 200 (see Figure 7), the rack 200 has a plate body 201 and a plurality of setting holes 202 formed in the plate body 201, and the rack 200 is exemplarily but not limitatively a server rack 200. The tool-free quick-mount slide rail 100 comprises a bracket 1, a joint sliding module 2, a leaf spring 3, and a joint buckle 4. It is to be noted that the bracket 1 is only partially shown in the drawings, and the tool-free quick-mount slide rail 100 further comprises a plurality of slide rail pieces (not shown in the drawings) connected with the bracket 1, which will not be described herein.

[0021] The bracket 1 has a side plate 11 extending along a front-rear direction D1 and an up-down direction D2, a front plate 12 extending from a front edge of the side plate 11 along a left-right direction D3 and used for abutting against the plate body 201 of the rack 200, and two positioning plates 13 extending from the side plate 11 along the left-right direction D3 and oppositely arranged in the up-down direction D2. The side plate 11 of the bracket 1 has two guide grooves 111 penetrating along the left-right direction D3 and extending along the front-rear direction D1. The front plate 12 has two through holes 121 arranged along the up-down direction D2. Each of the positioning plates 13 has a positioning groove 131 in a curved shape, and the positioning groove 131 has a plurality of positioning groove portions 131a, and the number of the positioning groove portions 131a is exemplarily but not limitatively three.

[0022] Referring to Figures 3 to 6 The joint sliding module 2 is arranged in the bracket 1 and can move along the front-rear direction D1 relative to the side plate 11 between a plurality of locking positions. The number of the locking positions corresponds to the number of the positioning groove portions 131a and is three. The joint sliding module 2 comprises a joint sliding block 21, a positioning rod 22, two positioning elastic pieces 23, two sliding sleeve cylindrical joints 24, two first elastic pieces 25, two sliding sleeve square column joints 26, and two second elastic pieces 27.

[0023] The joint sliding block 21 has a block body 211, two multi-stage cylindrical joints 212 extending forwardly from the block body 211 and respectively corresponding to the two through holes 121 of the front plate 12, and two guide columns 213 protruding from the block body 211 and respectively slidably arranged in the two guide slots 111 along the front-rear direction D1. The block body 211 is located between the two positioning plates 13 of the bracket 1, that is, the two positioning plates 13 are respectively located above and below the block body 211 of the joint sliding block 21. The block body 211 of the joint sliding block 21 has two protrusions 211a located rearward and arranged along the up-down direction D2, and two sliding grooves 211b penetratingly formed in the two protrusions 211a along the up-down direction D2 and extending along the left-right direction D3. Each of the multi-stage cylindrical joints 212 has a plurality of cylindrical segments 212a with a gradually reduced outer diameter from rear to front, and in the present embodiment, the number of the cylindrical segments 212a is three corresponding to the number of the locking positions. The joint sliding block 2 can slide relative to the side plate 11 through the cooperation of the guide slots 111 and the guide columns 213, for example, the guide columns 213 can be locked with washers and screws, and it should be noted that the number of the guide slots 111 and the guide columns 213 can also be one or more than three, which is not limited by the present embodiment.

[0024] The positioning rod 22 extends along the up-down direction D2 and is slidably arranged in the two sliding grooves 211b along the left-right direction D3, and both ends of the positioning rod 22 are respectively slidably arranged in the positioning slots 131 of the two positioning plates 13. The two positioning elastic members 23 are respectively arranged in the two sliding grooves 211b, and the two positioning elastic members 23 are used to push the positioning rod 22 in the left-right direction D3 to position the positioning rod 22 in the positioning slot part 131a of the positioning slot 131.

[0025] When the joint sliding module 2 is in any of the locking positions, the two positioning elastic members 23 position the positioning rods 22 in one of the positioning groove sections 131a of the positioning grooves 131 of the two positioning plates 13, at which time the two positioning plates 13 allow the positioning rods 22 to abut against the rear side. Moreover, one of the cylindrical sections 212a of each of the multi-stage cylindrical joints 212 protrudes forward from the front plate 12 by at least a preset distance to be inserted into the setting hole 202 of the plate body 201. The preset distance may, for example, be the thickness of the plate body 201 in the front-rear direction. Since the two positioning plates 13 allow the positioning rods 22 to abut against the rear side when the joint sliding module 2 is in any of the locking positions, the two multi-stage cylindrical joints 212 of the joint sliding module 2 can be prevented from retracting rearward. By adjusting the positions of the two multi-stage cylindrical joints 212 of the joint sliding module 2 in the front-rear direction D1, any of the cylindrical sections 212a of each of the multi-stage cylindrical joints 212 can protrude forward from the front plate 12 abutting against the plate body 201 of the rack 200 by at least the preset distance to be inserted into the setting hole 202 of the plate body 201. In this way, the rack 200 and the tool-free quick-mounting slide rail 100 can be prevented from forming an excessively long force arm, and the stability of the assembly of the rack 200 and the tool-free quick-mounting slide rail 100 can be improved.

[0026] The two sliding sleeve cylindrical joints 24 are respectively slidably sleeved on the two multi-stage cylindrical joints 212, and the two first elastic members 25 are sleeved on the two multi-stage cylindrical joints 212 and clamped between the block body 211 of the joint sliding block 21 and the two sliding sleeve cylindrical joints 24. Each of the sliding sleeve cylindrical joints 24 has a cylindrical joint portion 241 and a first abutting portion 242 located rearward of the cylindrical joint portion 241. The two first elastic members 25 drive the two sliding sleeve cylindrical joints 24 to move forward, so that the first abutting portions 242 of the two sliding sleeve cylindrical joints 24 abut against the rear side of the front plate 12, and the cylindrical joint portions 241 of the two sliding sleeve cylindrical joints 24 respectively protrude forward from the two through holes 121 by at least the preset distance.

[0027] The two sliding sleeve square column joints 26 are respectively slidably sleeved on the two multi-stage cylindrical joints 212, and the two second elastic members 27 are sleeved on the two multi-stage cylindrical joints 212 and clamped between the two sliding sleeve square column joints 26 and the block body 211 of the joint sliding block 21. The width of the two second elastic members 27 is greater than that of the two first elastic members 25 to avoid interference with the two first elastic members 25. Each of the sliding sleeve square column joints 26 has a square column joint portion 261 and a second abutting portion 262 located behind the square column joint portion 261. The two second elastic members 27 drive the two sliding sleeve square column joints 26 to move forward, so that the second abutting portions 262 of the two sliding sleeve square column joints 26 abut against the rear side of the front plate 12, and the square column joint portions 261 of the two sliding sleeve square column joints 26 protrude forward from the two through holes 121 by at least the preset distance. Specifically, the width of the square column joint portion 261 of each of the two sliding sleeve square column joints 26 is greater than that of the cylindrical joint portion 241 of the two sliding sleeve cylindrical joints 24, and the square column joint portion 261 of each of the two sliding sleeve square column joints 26 is formed with a receiving groove 261a for accommodating the cylindrical joint portion 241 of the corresponding sliding sleeve cylindrical joint 24. The tool-free quick-mount sliding rail 100 can be provided on more types of racks 200 through the two sliding sleeve cylindrical joints 24 and the two sliding sleeve square column joints 26.

[0028] The joint buckle 4 is provided on the side plate 11 of the bracket 1 through the plate spring 3, and is used for buckling on the rack 200 to generate an auxiliary fixing effect.

[0029] The following describes the assembly situation of the tool-free quick-mount sliding rail 100 and various racks 200 with different size setting holes 202.

[0030] Referring to Figure 7 and Figure 8 , first, when the tool-free quick-mount sliding rail 100 is provided on the rack 200 with a larger square hole (for example, a 9.5 mm square hole) setting hole 202, the front plate 12 of the bracket 1 abuts against the plate body 201 of the rack 200, and the square column joint portion 261 of each of the sliding sleeve square column joints 26 protrudes forward from the corresponding through hole 121 by at least the preset distance to be inserted into the setting hole 202 of the plate body 201.

[0031] Referring to Figure 9When the tool-less quick-mount slide rail 100 is set in the rack 200 with the setting holes 202 being larger round holes (for example, 7.1 mm round holes), the front plate 12 of the bracket 1 is abutted against the plate body 201 of the rack 200 in the front direction, and each of the slide sleeve square column joints 26 is retracted in the rear direction due to the blockage of the plate body 201. Each of the slide sleeve column joints 24 protrudes in the front direction from the corresponding through hole 121 by at least the preset distance to be inserted into the setting hole 202 of the plate body 201.

[0032] Referring to Figure 10 When the tool-less quick-mount slide rail 100 is set in the rack 200 with the setting holes 202 being smaller round holes (for example, 4.8 mm round holes), the front plate 12 of the bracket 1 is abutted against the plate body 201 of the rack 200 in the front direction, and each of the slide sleeve square column joints 26 and each of the slide sleeve column joints 24 is retracted in the rear direction due to the blockage of the plate body 201. The assembler can hold the two ends of the positioning rod 22 by fingers to operate the positioning rod 22, thereby adjusting the joint sliding module 2 to the locking position located in the frontmost position, so that the column segment 212a located in the rearmost position of each of the multi-stage column joints 212 (the column segment 212a with the largest outer diameter) protrudes in the front direction from the corresponding through hole 121 by at least the preset distance to be inserted into the setting hole 202 of the plate body 201.

[0033] Referring to Figure 11 When the tool-less quick-mount slide rail 100 is set in the rack 200 with the setting holes 202 being smaller round holes (for example, 4.8 mm round holes), the front plate 12 of the bracket 1 is abutted against the plate body 201 of the rack 200 in the front direction, and each of the slide sleeve square column joints 26 and each of the slide sleeve column joints 24 is retracted in the rear direction due to the blockage of the plate body 201. The assembler can hold the two ends of the positioning rod 22 by fingers to operate the positioning rod 22, thereby adjusting the joint sliding module 2 to the locking position located in the frontmost position, so that the column segment 212a located in the rearmost position of each of the multi-stage column joints 212 (the column segment 212a with the largest outer diameter) protrudes in the front direction from the corresponding through hole 121 by at least the preset distance to be inserted into the setting hole 202 of the plate body 201.

[0034] Referring to Figure 12When the tool-less quick-mount slide rail 100 is set in the rack 200 with the setting holes 202 being minimum round holes (for example, 3.8 mm round holes), the front plate 12 of the bracket 1 is abutted against the plate body 201 of the rack 200 in front, and each of the slide sleeve square column joint 26 and each of the slide sleeve round column joint 24 is retracted backward by the plate body 201. The assembler can hold the two ends of the positioning rod 22 with fingers to operate the positioning rod 22, thereby adjusting the joint sliding module 2 to the rearmost locking position, so that the frontmost round column segment 212a (the round column segment 212a with the smallest outer diameter) of each of the multi-stage round column joints 212 protrudes forward from the corresponding through hole 121 by at least the preset distance, so as to be inserted into the setting hole 202 of the plate body 201.

[0035] In summary, the joint sliding module 2 in the present application can move along the front-rear direction D1 between the plurality of locking positions relative to the side plate 11, thereby adjusting the positions of the two multi-stage round column joints 212 of the joint sliding module 2 in the front-rear direction D1, so that any of the round column segments 212a of each of the multi-stage round column joints 212 can protrude forward from the front plate 12 abutting against the plate body 201 of the rack 200 by at least a preset distance, so as to be inserted into the setting hole 202 of the plate body 201. In this way, the force arm between the rack 200 and the tool-less quick-mount slide rail 100 can be avoided, and the stability of the assembly between the rack 200 and the tool-less quick-mount slide rail 100 is better.

[0036] The above is only an embodiment of the present application, and cannot limit the scope of the present application. Any simple equivalent changes and modifications made according to the claims and the content of the specification of the present application are still within the scope of the present application.
