[0020] See also Figures 1 to 4 An embodiment of the tool-free quick-install slide rail 100 of the utility model is suitable for being installed in 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 can be, for example but not limited to, a server rack 200. The tool-free quick-install slide rail 100 includes a bracket 1, a joint sliding module 2, a leaf spring 3, and a joint buckle 4. It should be noted that only a partial portion of the bracket 1 is shown in the accompanying drawings, and the tool-free quick-install slide rail 100 also includes a plurality of slide rail members (not shown) connected to the bracket 1, which will not be described in detail here.

[0021] The bracket 1 has a side plate 11 extending along a front-to-back direction D1 and an up-to-down direction D2, a front plate 12 extending from the front edge of the side plate 11 along a left-to-right direction D3 and used to abut against the plate body 201 of the frame 200, and two positioning plates 13 extending from the side plate 11 along the left-to-right direction D3 and facing each other up and down. The side plate 11 of the bracket 1 has two guide grooves 111 penetrating along the left-to-right direction D3 and extending along the front-to-back direction D1. The front plate 12 has two through holes 121 arranged along the up-to-down direction D2. Each of the positioning plates 13 has a curved positioning groove 131, and the positioning groove 131 has a plurality of positioning groove portions 131a. The number of the positioning groove portions 131a is, for example, three, but is not limited thereto.

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

[0023] The joint sliding block 21 has a body 211, two multi-step cylindrical joints 212 extending forward from the body 211 and corresponding to the two through holes 121 of the front plate 12, and two guide posts 213 protruding from the body 211 and respectively slidably disposed in the two guide grooves 111 along the front-back direction D1. The 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 body 211 of the joint sliding block 21. The body 211 of the joint sliding block 21 has two protrusions 211a relatively located at the rear and arranged along the up-down direction D2, and two slide grooves 211b formed through 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 sections 212a whose outer diameters gradually decrease from the back to the front. In this embodiment, the number of the cylindrical sections 212a corresponds to the number of the locking positions, which is three. Through the cooperation between the guide groove 111 and the guide column 213, the joint sliding module 2 can slide relative to the side plate 11. For example, the guide column 213 can be locked with a gasket and a screw. It should be noted that the number of the guide groove 111 and the guide column 213 can also be one or more than three, and is not limited to this embodiment.

[0024] The positioning rod 22 extends along the up-down direction D2 and can be slidably disposed in the two slide grooves 211b along the left-right direction D3. Both ends of the positioning rod 22 can be slidably disposed in the positioning grooves 131 of the two positioning plates 13. The two positioning elastic members 23 are respectively disposed in the two slide grooves 211b, and the two positioning elastic members 23 are used to push the positioning rod 22 in the left-right direction D3 so that the positioning rod 22 is positioned in each of the positioning groove portions 131a of the positioning groove 131.

[0025] When the joint sliding module 2 is in any of the locking positions, the two positioning elastic members 23 position the positioning rod 22 in one of the positioning groove portions 131a of the positioning grooves 131 of the two positioning plates 13, and at this time, the two positioning plates 13 provide a backing for the positioning rod 22 to lean against. In addition, one of the cylindrical sections 212a of each of the multi-step 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 can be, for example, the thickness of the plate body 201 in the front-to-back direction. Since the two positioning plates 13 provide a backing for the positioning rod 22 to lean against when the joint sliding module 2 is in any of the locking positions, the two multi-step cylindrical joints 212 of the joint sliding module 2 can be prevented from retreating backward. By adjusting the positions of the two multi-step cylindrical joints 212 of the joint sliding module 2 in the front-to-back direction D1, any of the cylindrical sections 212a of each of the multi-step cylindrical joints 212 can be used to lean against the front plate 12 of the plate body 201 of the rack 200 and protrude forward by at least the preset distance, so as to be inserted into the setting hole 202 of the plate body 201. In this way, it is possible to avoid an excessively long force arm between the rack 200 and the tool-free quick-install slide rail 100, and to improve the stability of the assembly between the rack 200 and the tool-free quick-install slide rail 100.

[0026] The two sliding sleeve cylindrical joints 24 are respectively slidably mounted on the two multi-step cylindrical joints 212, and the two first elastic members 25 are mounted on the two multi-step cylindrical joints 212 and sandwiched between the two sliding sleeve cylindrical joints 24 and the block body 211 of the joint sliding block 21. Each of the sliding sleeve cylindrical joints 24 has a cylindrical joint portion 241 and a first abutting portion 242 located behind 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 forward against the rear side surface of the front plate 12, and the cylindrical joint portions 241 of the two sliding sleeve cylindrical joints 24 protrude forward from the two through holes 121 by at least the preset distance.

[0027] The two sliding square column joints 26 are respectively slidably mounted on the two multi-step cylindrical joints 212, the two second elastic members 27 are mounted on the two multi-step cylindrical joints 212 and sandwiched between the two sliding square column joints 26 and the block body 211 of the joint sliding block 21, and the width of the two second elastic members 27 is greater than the two first elastic members 25 to avoid interference with the two first elastic members 25. Each of the sliding 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 square column joints 26 to move forward, so that the second abutting portions 262 of the two sliding square column joints 26 abut against the rear side surface of the front plate 12, and the square column joint portions 261 of the two sliding 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 the two sliding square column joints 26 is greater than the cylindrical joint portion 241 of the two sliding cylindrical joints 24, and the square column joint portion 261 of each sliding square column joint 26 is formed with a receiving groove 261a for accommodating the cylindrical joint portion 241 of the corresponding sliding cylindrical joint 24. The two sliding cylindrical joints 24 and the two sliding square column joints 26 enable the tool-free quick-install slide rail 100 to be installed in more types of racks 200.

[0028] The connector buckle 4 is disposed on the side plate 11 of the bracket 1 through the leaf spring 3 , and the connector buckle 4 is used to buckle on the frame 200 to produce an auxiliary fixing effect.

[0029] The following describes the assembly scenarios of the tool-free quick-install slide rail 100 and various racks 200 having holes 202 of different sizes.

[0030] See also Figure 7 and Figure 8 First, when the tool-free quick-release slide rail 100 is set on the rack 200 whose setting hole 202 is a larger square hole (for example, a 9.5 mm square hole), the front plate 12 of the bracket 1 is pressed forward against the plate body 201 of the rack 200, and the square column joint portion 261 of each sliding square column joint 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] See also Fig. 9When the tool-free quick-install slide rail 100 is installed in the rack 200 whose setting hole 202 is a relatively large round hole (e.g., a 7.1 mm round hole), the front plate 12 of the bracket 1 is pressed forward against the plate body 201 of the rack 200, and each of the sliding sleeve square column joints 26 is blocked by the plate body 201 and retracts backward. Each of the sliding sleeve cylindrical joints 24 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.

[0032] See also Fig.10 When the tool-free quick-install slide rail 100 is installed in the rack 200 whose setting hole 202 is a second-large circular hole (e.g., a 4.8 mm circular hole), the front plate 12 of the bracket 1 is pressed forward against the plate body 201 of the rack 200, and each of the sliding square column joints 26 and each of the sliding cylindrical joints 24 are blocked by the plate body 201 and retract backward. 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 locking position located at the front, so that the rearmost cylindrical section 212a (the cylindrical section 212a with the largest outer diameter) of each of the multi-stage cylindrical 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.

[0033] See also Fig.11 When the tool-free quick-install slide rail 100 is installed in the rack 200 whose setting hole 202 is a secondary round hole (e.g., a 4.2 mm or 4.0 mm round hole), the front plate 12 of the bracket 1 is pressed forward against the plate body 201 of the rack 200, and each of the sliding square column joints 26 and each of the sliding cylindrical joints 24 are blocked by the plate body 201 and retract backward. 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 locking position located in the middle in the front-to-back direction, so that the cylindrical section 212a (the cylindrical section 212a with the second largest outer diameter) located in the middle of each of the multi-step cylindrical 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.

[0034] See also Fig.12When the tool-free quick-install slide rail 100 is installed in the rack 200 whose setting hole 202 is the smallest circular hole (e.g., a 3.8 mm circular hole), the front plate 12 of the bracket 1 is pressed forward against the plate body 201 of the rack 200, and each of the sliding square column joints 26 and each of the sliding cylindrical joints 24 are blocked by the plate body 201 and retract backward. 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 cylindrical section 212a (the cylindrical section 212a with the smallest outer diameter) of each of the multi-step cylindrical 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 utility model can move between multiple locking positions along the front-to-back direction D1 relative to the side plate 11, thereby adjusting the positions of the two multi-step cylindrical joints 212 of the joint sliding module 2 in the front-to-back direction D1, so that any of the cylindrical sections 212a of each of the multi-step cylindrical joints 212 can be used to lean against the front plate 12 of the plate body 201 of the rack 200 and protrude forward by at least a preset distance, so as to be inserted into the setting hole 202 of the plate body 201. In this way, it is possible to avoid the formation of an excessively long force arm between the rack 200 and the tool-free quick-install slide rail 100, and to make the assembly stability between the rack 200 and the tool-free quick-install slide rail 100 better.
