Detailed Implementation

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] Example: This embodiment discloses a chassis lock.

[0023] like Figure 1 As shown, a chassis lock is used for chassis 3, and nails 31 are provided on both sides of chassis 3. For example, chassis 3 is a server chassis 3, which is rectangular in shape.

[0024] like Figure 2 As shown, the chassis lock includes a slide rail 1 and a lock assembly 2.

[0025] In this example, the first side is the side away from chassis 3, and the second side is the side closer to chassis 3. The first end is the end closer to the pull-out direction of chassis 3, and the second end is the end away from the pull-out direction of chassis 3.

[0026] The slide rail 1 has a first through hole 12 and a slot 11, with the slot 11 located at the first end of the first through hole 12. For example, the slide rail 1 is an inner rail.

[0027] The lock assembly 2 includes a fixing part 22, a locking part 21, and an unlocking part 24.

[0028] The fixing part 22 is fixed to the first surface of the slide rail 1. For example, an extension part 121 extends from the first end of the slide rail 1 into the second end within the first through hole 12. A rivet block 122 is provided on the first surface of the extension part 121. A rivet hole 221 is provided on the fixing part 22. The rivet block 122 is pressed into the rivet hole 221 to realize the riveting of the locking assembly 2 and the slide rail 1.

[0029] The locking part 21 is connected to the first end of the fixing part 22, and a second through hole 211 is formed in the locking part 21. The unlocking part 24 is connected to the second end of the fixing part 22, and its position corresponds to the first through hole 12. The rod of the nail part 31 is inserted into the slot 11, the nail head of the nail part 31 passes through and protrudes from the first surface of the slide rail 1, and the nail head is inserted into the second through hole 211 to prevent the nail part 31 from moving out of the slot 11.

[0030] like Figure 2 As shown, exemplarily, the slot 11 includes a first slot 111 and a second slot 112. The first slot 111 is formed on the slide rail 1, through which the head of the nail part 31 passes. The second slot 112 is formed on the slide rail 1, connecting to the second end of the first slot 111, through which the rod of the nail part 31 passes. The inner diameter of the second slot 112 is smaller than the outer diameter of the nail head. After the rod is engaged in the second slot 112, it prevents the nail head from disengaging from the slide rail 1. The first end of the nail head abuts against the first end inside the second through hole 211 to restrict the nail part 31 from moving out of the slot 11 toward the first end. Preferably, the nail head of the nail part 31 is circular, and the first end inside the second through hole 211 is arc-shaped to cooperate with the nail head.

[0031] like Figure 2 As shown, the fixing part 22, locking part 21, and unlocking part 24 are integrally formed. The fixing part 22 is connected to the middle of the second end of the locking part 21, and the upper and lower ends of the unlocking part 24 and the locking part 21 are connected by a connecting rod 23. Specifically, an arc-shaped groove 25 is formed on the lock assembly 2, with the opening of the arc-shaped groove 25 facing the first end. The inner side of the arc-shaped groove 25 corresponds to the fixing part 22, the second end of the arc portion of the arc-shaped groove 25 corresponds to the unlocking part 24, and the outer side of the straight edge of the arc-shaped groove 25 corresponds to the connecting rod 23.

[0032] like Figure 2 As shown, further, the first surface of the locking part 21 is provided with a first protrusion 212 at the first end of the second through hole 211, and a concave block 213 is provided at the middle of the second end of the first protrusion 212. The second end of the concave block 213 abuts against the nail head of the nail part 31. The contact area between the nail head and the concave block 213 is small, which reduces the friction force when unlocking.

[0033] like Figure 2 As shown, further, the first surface of the unlocking part 24 is provided with a second protrusion 241, which facilitates pressing to unlock.

[0034] In this embodiment, as Figure 3 As shown, during installation, after the locking assembly 2 is fixed to the slide rail 1 by the fixing part 22, the nail part 31 is passed through the slot 11, and the nail head of the nail part 31 passes through the first groove 111 and protrudes from the first surface of the slide rail 1, thus opening the locking part 21. Figure 4 As shown, the rod of the nail part 31 then engages with the second groove 112, and the locking part 21 resets under its own elastic force, causing the nail head to engage with the second through hole 211 of the locking part 21, restricting the movement of the nail part 31 relative to the groove 11, thereby fixing the slide rail 1 to the side of the chassis 3. To unlock, press the unlocking part 24 to lift the locking part 21, allowing the nail part 31 to be removed from the groove 11, thus separating the chassis 3 from the slide rail 1.
