[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0032] like Figures 1 to 6As shown, the technical solution of this embodiment is applied, and the angle adjustment lock includes: a first lock seat 10, a second lock seat 20, a driving member 30 and an arc guide member 40. The second lock seat 20 is located at one side of the first lock seat 10. The driving member 30 is connected between the first lock seat 10 and the second lock seat 20, and the driving member 30 includes a driving rod 31 and a pendulum block 32 swingably arranged on the first lock seat 10. The driving rod 31 is telescopically arranged on the pendulum block 32, and one end of the driving rod 31 is movably connected to the second lock seat 20. The driving rod 31 is telescopic and drives the pendulum block 32 to move so that the first lock seat 10 and the second lock seat 20 are close to each other or away from each other. The second lock seat 20 is provided with a guide hole 21. The first end of the arc guide member 40 extends into the guide hole 21 and cooperates with the guide hole 21 for guidance, and the second end of the arc guide member 40 is connected to the first lock seat 10.

[0033] In this way, when the driving rod 31 is extended and retracted on the swing block 32, the length of the driving rod 31 between the swing block 32 and the second lock seat 20 changes, so that the swing block 32 and the second lock seat 20 are close to each other or away from each other, so that the first lock seat 10 can be close to each other or away from each other. When the first lock seat 10 can be close to each other or away from each other, the guiding cooperation between the arc guide 40 and the guide block enables the relative movement between the first lock seat 10 and the second lock seat 20 to move along the guiding direction of the arc guide 40, so as to drive the change of the angle between the front surfaces of the two adjacent display modules 62. In addition, the setting of the swing block 32 and the setting that one end of the driving rod 31 is movably connected to the second lock seat 20 can avoid the movement of the first lock seat 10 and the second lock seat 20 along the guiding direction of the arc guide 40, so that the first lock seat 10 and the second lock seat 20 can move more smoothly along the guiding direction of the arc guide 40. By driving the driving rod 31, the angle between the first lock seat 10 and the second lock seat 20 can be adjusted to adjust the angle between the two adjacent boxes 61 and the angle between the front surfaces of the two adjacent display modules 62. This operation is simple and fast, and the work efficiency is improved. Therefore, the technical solution of this embodiment effectively solves the problem of troublesome operation when adjusting the angle between the front surfaces of the two adjacent display modules in the related art.

[0034] like Figures 1 to 6 As shown, the driving rod 31 is a screw rod, and a threaded hole matched with the screw rod thread is provided in the pendulum block 32. The screw rod rotates along its axis so that the screw rod drives the pendulum block 32 to move. The structure of the screw rod and the threaded hole is simple and easy to process. The screw rod is rotated so that the length of the screw rod between the pendulum block 32 and the second lock seat 20 can be adjusted to drive the pendulum block 32 to approach or move away from the second lock seat 20.

[0035] In this embodiment, a driving handle is provided on one end of the screw rod which is away from the second lock seat 20 , and an operator controls the rotation of the screw rod by rotating the driving handle.

[0036] In other embodiments, a rack portion is provided on the driving rod 31, and a rotatable gear is provided in the swing block 32. The driving gear rotates to drive the rack portion to extend and retract in the swing block 32, so that the swing block 32 moves relative to the second lock seat 20.

[0037] like Figures 1 to 6 As shown, the driving member 30 further includes a connecting seat 33 detachably disposed on the second lock seat 20, and one end of the driving rod 31 is movably connected to the connecting seat 33. The arrangement of the connecting seat 33 facilitates the connection and separation of the driving member 30 and the second lock seat 20. The connecting seat 33 is separated from the second lock seat 20, so that one end of the driving rod 31 can be separated from the second lock seat 20, so that the two adjacent boxes 61 can be separated.

[0038] like Figures 1 to 6 As shown, a ball head 34 is provided at one end of the driving rod 31, and a joint is provided on the connecting seat 33. The ball head 34 is rotatably arranged in the joint and cooperates with the joint stop. The structure of the ball head 34 and the joint is simple and easy to process. In addition, the cooperation between the ball head 34 and the joint facilitates the rotation of one end of the driving member 30 relative to the connecting seat 33, so that when the angle between the first lock seat 10 and the second lock seat 20 is adjusted, the driving rod 31 can rotate relative to the connecting seat 33 to adapt to the swing of the first lock seat 10 and the second lock seat 20.

[0039] like Figures 1 to 6 As shown, the driving member 30 also includes a connecting rod 35 connected between the connecting seat 33 and the second lock seat 20. The swing block 32 drives the driving rod 31 to swing so that the axis of the driving rod 31 forms a swing plane, and the axis of the connecting rod 35 is arranged at an angle to the swing plane. A positioning hole 22 is arranged on the second lock seat 20. The connecting rod 35 can be floatingly arranged on the connecting seat 33 to have a connecting position extending outside the connecting seat 33 and a retracted position retracted into the connecting seat 33. When the connecting rod 35 is in the connecting position, the connecting rod 35 extends into the positioning hole 22 and is positioned and matched with the positioning hole 22. When the connecting rod 35 is in the retracted position, the connecting rod 35 retracts into the connecting seat 33 so that the connecting seat 33 can be separated from the second lock seat 20. In this way, the connection or separation of the connecting seat 33 and the second lock seat 20 can be controlled by controlling the floating of the connecting rod 35, and the operation is simple and quick, which further improves the work efficiency.

[0040] In this embodiment, the axis of the connecting rod 35 is perpendicular to the swing plane, that is, the axis of the connecting rod 35 is parallel to the swing axis of the pendulum block 32. In this way, one end of the driving rod 31 can be more reliably connected to the second lock seat 20 through the connecting rod 35 and the connecting seat 33.

[0041] like Figures 1 to 6 As shown, the driving member 30 further includes an elastic member 36 disposed in the connecting seat 33, and the elastic member 36 abuts between the connecting seat 33 and the connecting rod 35. The elastic member 36 applies a force toward the second lock seat 20 to the connecting rod 35 so that the connecting rod 35 can be kept in the connecting position. The setting of the elastic member 36 enables the connecting rod 35 to be kept in the connecting position without being acted upon by an external force, so that the connection between the connecting rod 35, the connecting seat 33 and one end of the driving rod 31 and the second lock seat 20 is more reliable.

[0042] like Figures 1 to 6 As shown, the first lock seat 10 is provided with a first lug 11 and a second lug 12 at intervals, and the swing block 32 is rotatably connected between the first lug 11 and the second lug 12. The arrangement of the first lug 11 and the second lug 12 facilitates the installation of the swing block 32 on the first lock seat 10. Moreover, the swing block 32 is rotatably connected between the first lug 11 and the second lug 12, which can better limit the range of movement of the swing block 32, so that the swing block 32 can better swing in a direction perpendicular to the front surface of the display module 62.

[0043] like Figures 1 to 6 As shown, a connecting hole 41 is provided on the second end of the arc-shaped guide member 40. The angle adjustment lock further includes a first fastener 51 extending into the first lock seat 10. The first fastener 51 extends into the connecting hole 41 to fix the second end of the arc-shaped guide member 40 in the first lock seat 10. The connecting hole 41 and the first fastener 51 have a simple structure, which facilitates the installation and removal of the arc-shaped guide member 40 on the first lock seat 10.

[0044] In this embodiment, the angle adjustment lock further includes a positioning bead that is floatably disposed on the side wall of the guide hole 21, and a plurality of positioning grooves are arranged at intervals on the arc-shaped guide member 40. The positioning bead floats to have a positioning position that is positioned and matched with one of the plurality of positioning grooves and an adjustment position that is separated from the positioning groove. When the positioning bead is positioned and matched with two adjacent positioning grooves, the angle between the front surfaces of two adjacent display modules 62 differs by 5 degrees.

[0045] like Figures 1 to 6As shown, the angle adjustment lock also includes a second fastener 52 that can be telescopically extended into the second lock seat 20, and the second fastener 52 is telescopic to have an abutting position for abutting with the arc-shaped guide member 40 and a avoiding position for avoiding with the arc-shaped guide member 40. The setting of the second fastener 52 facilitates the fixation of the arc-shaped guide member 40 in the guide hole 21. By driving the second fastener 52 to switch between the abutting position and the avoiding position, the movement or fixation of the arc-shaped guide member 40 in the guide hole 21 can be controlled, which is simple to operate and convenient for processing. In addition, the setting of the second fastener 52 enables the arc-shaped guide member 40 to be arbitrarily adjusted in the guide hole 21, so that the angle between the front surfaces of two adjacent display modules 62 can be infinitely adjusted.

[0046] In other embodiments, a guide hole 21 is provided on the first lock seat 10, and the second end of the arc-shaped guide member 40 is connected to the second lock seat 20. The angle adjustment lock further includes a second fastener 52 that can be telescopically extended into the first lock seat 10. The angle adjustment lock further includes a first fastener 51 that extends into the second lock seat 20. The first fastener 51 extends into the connecting hole 41 to fix the second end of the arc-shaped guide member 40 in the second lock seat 20.

[0047] It should be noted that when the angle between the front surfaces of two adjacent display modules 62 is 180 degrees, the LED display device is a flat screen. When the angle between the front surfaces of two adjacent display modules 62 is less than 180 degrees, the LED display device is an inner arc screen. When the angle between the front surfaces of two adjacent display modules 62 is greater than 180 degrees, the LED display device is an outer arc screen. By applying the technical solution of this embodiment, the angle between the front surfaces of two adjacent display modules 62 can be adjusted between 165 degrees and 195 degrees.

[0048] The present application also provides an LED display device, such as Figure 1 As shown, the LED display device includes a display module 62, a box body 61 disposed at the rear side of the display module 62, and an angle adjustment lock disposed on the box body 61, and the angle adjustment lock is the above-mentioned angle adjustment lock. Since the above-mentioned angle adjustment lock can solve the problem of troublesome operation when adjusting the angle between the front surfaces of two adjacent display modules in the related art, the LED display device with the angle adjustment lock can solve the same technical problem.
