The second guide portion 12 is guided and matched with the second transmission member 33. When the operating member 31 moves, the operating member 31 can drive the second lock seat 40 to move along the preset arc direction through the second transmission member 33, so that the first lock seat 20 and the second lock seat 40 are close to each other or away from each other along the preset arc direction, so as to adjust the angle between the first mounting surface and the second mounting surface. Two adjacent display units are respectively mounted on the first mounting surface and the second mounting surface. When the operating member 31 moves, the operating member 31 can drive the first lock seat 20 to move along the preset arc direction through the first transmission member 32, and the operating member 31 can drive the second lock seat 40 to move along the preset arc direction through the second transmission member 33, so that the first lock seat 20 and the second lock seat 40 are close to each other or away from each other along the preset arc direction, so as to adjust the angle between the first mounting surface and the second mounting surface, thereby adjusting the angle between the two adjacent display units.

[0046] like Figure 2 and Figure 3 As shown, the first transmission member 32 includes a first sliding rod 321 and a first transmission rod 322, the first sliding rod 321 is connected to the first lock seat 20, the first end of the first transmission rod 322 is sleeved on the first sliding rod 321, the second end of the first transmission rod 322 is rotatably connected to the operating member 31, and the first guide portion 11 is guided and matched with the first sliding rod 321. The first guide portion 11 is guided and matched with the first transmission member 32, so that the first sliding rod 321 is slidably arranged on the lock body 10 along the preset arc direction, and the second transmission member 33 includes a second sliding rod 331 and a second transmission rod 332, the second sliding rod 331 is connected to the second lock seat 40, the first end of the second transmission rod 332 is sleeved on the second sliding rod 331, the second end of the second transmission rod 332 is rotatably connected to the operating member 31, and the second guide portion 12 is guided and matched with the second sliding rod 331. The second guide portion 12 is guided and matched with the second transmission member 33, so that the second sliding rod 331 is slidably arranged on the lock body 10 along the preset arc direction.

[0047] Among them, when the operating member 31 moves, the operating member 31 can drive the first sliding rod 321 to move along the preset arc direction through the first transmission rod 322, and the operating member 31 can drive the second sliding rod 331 to move along the preset arc direction through the second transmission rod 332, so that the first lock seat 20 and the second lock seat 40 are close to or away from each other along the preset arc direction to adjust the angle between the first mounting surface and the second mounting surface.

[0048] like Figure 2 , Figure 3 as well as Figure 5As shown, the first guide portion 11 includes an arc groove 111 provided on the lock body 10, the center line of the arc groove 111 extends along a preset arc direction, and the first sliding rod 321 can be movably extended into the arc groove 111. When the operating member 31 drives the first sliding rod 321 to move through the first transmission rod 322, the arc groove 111 guides the moving path of the first sliding rod 321.

[0049] like Figure 2 , Figure 3 as well as Figure 5 As shown, the first guide portion 11 further includes a stopper 112 disposed on the lock body 10, the stopper 112 is located on a side of the first transmission member 32 away from the second transmission member 33, the stopper 112 has a matching curved surface 1121, the middle portion of the matching curved surface 1121 protrudes toward the first transmission rod 322, and the side wall of the first transmission rod 322 slidably cooperates with the matching curved surface 1121. When the operating member 31 drives the first sliding rod 321 to move through the first transmission rod 322, the side wall of the first transmission rod 322 slidably cooperates with the matching curved surface 1121 to guide the moving path of the first end of the first transmission rod 322, thereby guiding the moving path of the first sliding rod 321.

[0050] like Figure 2 and Figure 3 As shown, the operating member 31 includes an operating rod 311 and a connecting rod 312. The operating rod 311 is rotatably arranged on the lock body 10, and the connecting rod 312 is movably arranged on the lock body 10 along a preset straight line direction. The preset straight line direction, the rotation axis of the operating rod 311, and the axis direction of the first sliding rod 321 are arranged perpendicularly in pairs. The operating rod 311 is drivingly connected to the connecting rod 312, and the connecting rod 312 is drivingly connected to the first transmission rod 322 and the second transmission rod 332 respectively. The operating member 31 of the above structure is swung to make the operating rod 311 drive the connecting rod 312 to move along the preset straight line direction, so that the connecting rod 312 drives the first transmission rod 322 and the second transmission rod 332 to drive the first sliding rod 321 and the second sliding rod 331 to move along the second preset arc direction. When the operating member 31 is used to adjust the angle between the first mounting surface and the second mounting surface, the operating resistance can be reduced, so that the adjustment operation is convenient, fast, and labor-saving.

[0051] It should be noted that the preset straight line direction, the rotation axis of the operating rod 311 and the axial direction of the first sliding rod 321 are arranged perpendicular to each other, which means that the preset straight line direction is perpendicular to the rotation axis of the operating rod 311, the rotation axis of the operating rod 311 is perpendicular to the axial direction of the first sliding rod 321, and the preset straight line direction is perpendicular to the axial direction of the first sliding rod 321.

[0052] like Figures 2 to 4As shown, the first end of the connecting rod 312 is provided with a driving column 3121, and the first transmission rod 322 is provided with a first strip hole 3122, and the driving column 3121 is movably inserted into the first strip hole 3122. With the above structure, the smoothness of the movement of the first transmission rod 322 driven by the connecting rod 312 can be improved, and the movement of the driving column 3121 in the first strip hole 3122 can be used to prevent the first end of the connecting rod 312 and the first transmission rod 322 from being stuck.

[0053] like Figures 2 to 4 As shown, the first end of the operating rod 311 is the operating end, the second end of the operating rod 311 is provided with a connecting hole, the second end of the connecting rod 312 is provided with a second strip hole 3123, and the operating member 31 further includes a connecting pin 313 disposed in the connecting hole and the second strip hole 3123.

[0054] like Figures 2 to 5 As shown, a guide structure 50 is provided between the lock body 10 and the connecting rod 312, and the guide structure 50 guides the moving direction of the connecting rod 312. Specifically, the guide structure 50 includes a guide hole provided on the lock body 10, the guide hole extends along a preset straight line direction, and the driving column 3121 is movably provided in the guide hole.

[0055] like Figures 2 to 5 As shown, the adjustment assembly 30 further includes a first clamping plate 34, a second clamping plate 35, a matching plate 36 and a positioning structure. The first clamping plate 34 and the second clamping plate 35 are both arranged perpendicular to the rotation axis of the operating member 31. The first clamping plate 34 and the second clamping plate 35 are arranged on the lock body 10 at intervals in the direction of the rotation axis of the operating member 31. The matching plate 36 is arranged on the operating rod 311. The matching plate 36 extends into the interval between the first clamping plate 34 and the second clamping plate 35. The positioning structure is arranged between the first clamping plate 34 and the matching plate 36. The positioning structure is arranged between the second clamping plate 35 and the matching plate 36 to limit the movement of the matching plate 36 relative to the first clamping plate 34 and the second clamping plate 35. After the angle between the first mounting surface and the second mounting surface is adjusted to the right position, the positioning structure is used to limit the swing of the matching plate 36 and the operating rod 311.

[0056] like Figure 1 and Figure 2As shown, the positioning structure includes a fastener 37, which is rotatably inserted into the first clamping plate 34, and the fastener 37 is threadedly matched with the second clamping plate 35. When adjusting the angle between the first mounting surface and the second mounting surface, the fastener 37 is loosened, and the operating rod 311 is swung to drive the matching plate 36 to swing. After the angle between the first mounting surface and the second mounting surface is adjusted to the right position, the fastener 37 is locked to make the first clamping plate 34 and the second clamping plate 35 clamp the matching plate 36, thereby limiting the swing of the matching plate 36 and the operating rod 311.

[0057] Specifically, in this embodiment, the angle between the first mounting surface and the second mounting surface can be adjusted arbitrarily within the range of an inner arc of 165 degrees to an outer arc of 165 degrees.

[0058] like Figure 2 As shown, the positioning structure also includes a marble, which is arranged on the inner side wall of the first clamping plate 34 and / or the second clamping plate 35. The matching plate 36 is provided with at least two positioning grooves 361 corresponding to the marble, and the at least two positioning grooves 361 are arranged in the rotation direction of the operating rod 311. The marble can selectively extend into one of the at least two positioning grooves 361 and cooperate with the positioning groove 361. When adjusting the angle between the first mounting surface and the second mounting surface, the operating rod 311 is swung to drive the matching plate 36 to swing, and the marble moves between the at least two positioning grooves 361. When the marble extends into one of the at least two positioning grooves 361 and cooperates with the positioning groove 361, the marble and the positioning groove 361 provide precise positioning.

[0059] Specifically, in this embodiment, the included angle between the first mounting surface and the second mounting surface corresponding to two adjacent positioning grooves 361 changes to 5°.

[0060] like Figure 8 and Fig. 9 As shown, the first lock seat 20 includes a seat body 21 and a locking member 22. The seat body 21 is slidably arranged on the lock body 10, and the locking member 22 is movably arranged on the seat body 21. The locking member 22 has a locking state connected to the first transmission member 32 and an unlocking state separated from the first transmission member 32.

[0061] like Figure 8 and Fig. 9 As shown, a through hole 211 is provided on the base body 21, and a lock hole 221 corresponding to the through hole 211 is provided on the locking member 22. The first transmission member 32 also includes a latch 323. When the locking member 22 is in a locked state, the latch 323 is passed through the through hole 211 and the lock hole 221, and the latch 323 is respectively engaged with the through hole 211 and the lock hole 221. When the locking member 22 is in an unlocked state, the latch 323 is respectively separated from the through hole 211 and the lock hole 221.

[0062] Among them, the locking piece 22 is a pulling card piece, and the base 21 is installed on the display box. When disassembling the display box, it is only necessary to pull the locking piece 22 and switch the locking piece 22 to the unlocked state to separate the latch 323 and the base 21. When installing the display box, it is only necessary to pull the locking piece 22 and switch the locking piece 22 to the unlocked state, and place the base 21 on the lock body 10 so that the latch 323 passes through the through hole 211 and the lock hole 221. Then, the locking piece 22 is pulled and switched to the locked state, and the locking piece 22 and the latch 323 are connected, and the lock body 10 and the base 21 are connected, thereby simplifying the disassembly and assembly operations of the installation components and the display box.

[0063] like Figure 7 As shown, the latch 323 is coaxially arranged with the first sliding rod 321 at the upper end of the first sliding rod 321, and the latch 323 is movable relative to the first sliding rod 321 along its circumferential direction. The latch 323 has an upwardly extending engaging position and a downwardly retracted avoiding position. When the latch 323 is in the engaging position, the latch 323 penetrates the seat body 21. When the latch 323 is in the avoiding position, the latch 323 escapes from the seat body 21 and avoids the seat body 21. When installing the display box, the base 21 is installed on the display box, and the pin 323 is moved to the avoidance position so that the base 21 can slide onto the lock body 10 along the preset arc direction. When the through hole 211 is aligned with the pin 323, the locking member 22 is switched to the unlocked state, and the pin 323 is moved to the engaging position so that the pin 323 is inserted into the base 21. The locking member 22 is then switched to the locked state to connect the locking member 22 and the pin 323, and connect the lock body 10 and the base 21, thereby simplifying the disassembly and assembly operations of the installation components and the display box.

[0064] Furthermore, when disassembling the display box, the locking member 22 is switched to the unlocked state, and the latch 323 is moved to the avoidance position, so that the seat body 21 can leave the lock body 10 along the preset arc direction.
