[0019] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0020] like Figures 1-3 As shown, this utility model discloses a quick-assembly lock, a lock housing 1, and a threaded transmission structure disposed inside the lock housing 1.

[0021] The locking end of the threaded transmission structure passes through the lock housing 1, and the lock housing 1 is provided with an adjustment hole 2, which is connected to the adjustment end of the threaded transmission structure; wherein, the lock housing is fixed inside the equipment.

[0022] In order to drive the screw to rotate and perform linear transmission, in this embodiment, the screw transmission structure includes a screw gear 3 and a screw 4;

[0023] The lead screw gear 3 meshes with the threaded lead screw 4, and a locking screw 5 is installed at the front end of the threaded lead screw 4, which passes through the lock housing 1; the lead screw gear 3 is provided with a hexagonal hole 6, and the position of the hexagonal hole 6 corresponds to the position of the adjustment hole 2 on the housing. By rotating the lead screw gear, the threaded lead screw is driven to drive the locking screw 5 to be threadedly connected to the nut of another device.

[0024] Among them, the threaded screw 4 has twelve independent threads. For each revolution of the threaded screw 4, the lead of the screw gear 3 or nut is twelve times that of the threaded screw. At the same rotation speed, the threaded screw 4 moves faster.

[0025] Lead is the distance a lead screw travels per revolution; a 12-start lead screw has a larger lead, meaning it travels a longer distance per revolution, thus achieving a faster speed at the same rotational speed.

[0026] This invention reduces the load on each thread through a multi-start design, thereby reducing friction and wear, and enabling the lead screw to maintain high efficiency and stability even at high speeds.

[0027] One end has a 12-threaded screw with a diameter of 11.2mm, and the other end has a locking screw with a diameter of 8mm.

[0028] For a 12-start screw, the pitch is \( P_{12} = 12 \times p \), where \( p \) is the pitch per start.

[0029] For a single-head locking screw, the pitch is \( P_{1} = 1 \times p \).

[0030] The rotational speed \( N \) is inversely proportional to the pitch \( P \), i.e. \( N \propto \frac{1}{P} \).

[0031] Therefore, the relationship between the rotational speed \(N_{12} \) of the 12-start screw and the rotational speed \(N_{1} \) of the 1-start screw is as follows:

[0032] \[

[0033] \frac{N_{12}}{N_{1}} = \frac{P_{1}}{P_{12}} = \frac{1 \times p}{12 \times p} = \frac{1}{12}

[0034] \]

[0035] The rotational speed of the 12-head screw is 12 times that of the 1-head screw; that is, the rotational speed of the 1-head screw is 12 times that of the 12-head screw.

[0036] Among them, the lock case 1 includes an upper shell 7 and a lower shell 8;

[0037] The upper shell 7 and the lower shell 8 are spliced ​​together, and the splice of the upper shell 7 and the lower shell 8 is located in the gear receiving cavity and the transmission rod receiving cavity 14; the lead screw gear 3 is placed in the gear receiving cavity, and the threaded lead screw 4 is placed in the transmission rod receiving cavity.

[0038] The other end of the threaded screw 4 is provided with a spring groove 9, and a compression spring 10 is provided in the spring groove 9; the other end of the compression spring 10 is in contact with the spring baffle 11 on the upper shell 7.

[0039] In this embodiment, a locking screw 12 is provided on the upper shell 7 for splicing the upper shell and the lower shell 8, and the upper shell 7 and the lower shell 8 are locked and fixed together by the locking screw 12.

[0040] The user rotates the lead screw gear through the adjustment hole, the position of the adjustment hole corresponding to the hexagonal hole; rotating the lead screw gear causes the meshing threaded screw to rotate accordingly, thereby realizing the linear transmission of the locking screw; as the threaded screw moves, the locking screw extends outward and locks with the nut of another device, ensuring the stable splicing of the equipment.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
