The sliding part 32 has an arc-shaped structure and is slidably connected within the arc-shaped groove 12. The locking part 31 is connected to the rear end of the sliding part 32. The locking part 31 is located at the bottom... The rear side of the base 1; the adjustment component 4 is installed above the cover plate 2 and connected to the sliding part 32, used to adjust the position of the sliding part 32 in the arc-shaped slide groove 12; the adjustment component 4 is provided with a handle 41 for controlling the locking and unlocking of the sliding part 32; the lock head 3 slides on the arc-shaped slide groove 12 of the base 1 through the sliding part 32, and the position of the sliding part 32 is adjusted by adjusting the adjustment component 4, thereby adjusting the position and orientation of the locking part 31 of the lock head 3. The lock head 3 is installed on one side of the LED display installation box and connected to the lock cylinder of another LED display installation box. By adjusting the position of the lock head 3, the angle between the two LED display installation boxes can be adjusted. The handle 41 in the adjustment component 4 controls the unlocking and locking states, which is convenient for adjustment.
[0025] The cover plate 2 has toothed racks 22 formed on the left and right sides corresponding to the strip hole 21, and scale markings 23 (scale not shown) are provided on the outer sides of the two toothed racks 22 respectively; the sliding part 32 is provided with a first mounting groove 321; the adjusting assembly 4 also includes a locking slider 42, a connecting rod 43 and a mounting shaft 44; the lower end of the connecting rod 43 is fixed to the sliding part 32 by a first screw 431, and the upper end extends above the strip hole 21; the locking slider 42 is sleeved on the outside of the connecting rod 43; the locking slider 42 has a T-shaped structure. The device includes a pressing part 421 and a positioning part 422 connected to the bottom of the pressing part 421; the pressing part 421 is located above the cover plate 2; the bottom surface of the pressing part 421 is provided with a toothed groove 4211 that mates with the rack 22; the upper surface of the pressing part 421 is provided with an arc-shaped groove 4212 arranged in the longitudinal direction at the middle position; the positioning part 422 passes through the strip hole 21 and extends into the first mounting groove 321 of the sliding part 32; one end of the handle 41 is connected to a cam 411; the cam 411 rotates through the mounting shaft 44. The cam 411 is connected to the upper end of the connecting rod 43. The cam 411 contacts the arc-shaped groove 4212. The cam 411 is controlled to rotate around the axis of the mounting shaft 44 by the handle 41. During the rotation of the cam 411, when the part of the outer wall of the cam 411 that is far from the center of the cam 411 abuts against the arc-shaped groove 4212, the locking slider 42 is pressed against the cover plate 2. The toothed groove 4211 at the bottom of the locking slider 42 cooperates with the rack 22 on the cover plate 2 to lock it in place. Since the positioning part 422 of the locking slider 42 extends into the first mounting groove 321 of the sliding part 32, the locking slider 42 is locked in place. Therefore, after the locking slider 42 is fixed, the sliding part 32 is also fixed. When it is necessary to loosen the locking slider 42 for position adjustment, the handle 41 is reset. The part of the outer wall of the cam 411 that is closer to the center of the cam 411 contacts the arc-shaped groove 4212. At this time, the locking slider 42 is not locked. The locking slider 42 can be moved back and forth to adjust the position. Adjusting the position of the locking slider 42 will drive the sliding part 32 to move synchronously, thereby realizing the adjustment of the position of the sliding part 32. After the adjustment is completed, the locking slider 42 is locked and fixed by the handle 41 to complete the adjustment.
[0026] Two cams 411 are arranged in a front-to-back configuration; the upper end of the connecting rod 43 extends between the two cams 411, and this structure provides high connection stability.
[0027] The upper part of the outer wall of the cam 411 near the handle 41 is provided with a triangular limiting protrusion 4111. When the handle 41 is swung, the limiting protrusion 4111 abuts against the locking slider 42 to limit the swing angle.
[0028] In this design, the cam 411 has an elliptical structure. When the outer wall of the long axis of the cam 411 abuts against the arc-shaped groove 4212, it is in a locked state, and when the outer wall of the short axis of the cam 411 abuts against the arc-shaped groove 4212, it is in a released state.
[0029] The inner wall of the first mounting groove 321 is provided with a positioning recess 3211; the outer wall of the positioning part 422 is provided with a positioning protrusion 4211 that cooperates with the positioning recess 3211. By setting the positioning recess 3211 to cooperate with the positioning protrusion 4211, the positioning part 422 is prevented from rotating in the first mounting groove 321.
