[0017] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0018] like Figure 1-8 As shown, an arc-shaped lock assembly for a display screen is used to splice two adjacent display screens and adjust the connection angle between the two adjacent display screens. It includes an arc-shaped lock body 1 and an arc-shaped lock seat 2 for locking with the arc-shaped lock body 1. The arc-shaped lock body 1 includes a first frame fixing seat 3, a clamping plate 4 fixedly connected to the top of the first frame fixing seat 3, an arc-shaped slide 5 limited between the first frame fixing seat 3 and the clamping plate 4 and slidably along the arc of the first frame fixing seat 3, and a toggle-type locking mechanism 6 that passes through the clamping plate 4 and the arc-shaped slide 5 and extends into the first frame fixing seat 3. The toggle-type locking mechanism 6 is used to lock the arc-shaped slide 5. The arc-shaped lock seat 2 is a snap-lock seat. The outer arc surface of the arc-shaped slide 5 has a snap groove 7 for engaging with the arc-shaped lock seat 2.

[0019] The display screen uses an arc-shaped lock assembly for splicing two adjacent display screens and adjusting the connection angle between the two adjacent display screens. It adopts an arc-shaped lock body 1 and an arc-shaped lock seat 2 for locking and engaging with the arc-shaped lock body 1. The arc-shaped lock body 1 includes a first frame fixing seat 3, a clamping plate 4 fixedly connected to the top of the first frame fixing seat 3, an arc-shaped slide 5 limited between the first frame fixing seat 3 and the clamping plate 4 and slidably along the arc of the first frame fixing seat 3, and a toggle-type locking mechanism 6 that passes through the clamping plate 4 and the arc-shaped slide 5 and extends into the first frame fixing seat 3. The toggle-type locking mechanism 6 is used to lock the arc-shaped slide 5. The arc-shaped lock seat 2 is a snap-lock seat, and the outer arc surface of the arc-shaped slide 5 has a snap groove 7 for engaging with the arc-shaped lock seat 2. When two displays are used in an arc splicing configuration, the arc slide 5 of one display slides along the arc of the first frame fixing seat 3 to adjust the position angle of the arc slide 5. Then, the toggle locking mechanism 6 is used to lock the arc slide 5 to prevent it from shifting. Finally, the arc lock seat 2 of the adjacent display is fastened to the locking groove 7. This avoids the need to use bolts, nuts and other locking parts to adjust the connection angle of the arc lock assembly, making it more convenient and faster, and improving the efficiency of display splicing.

[0020] Furthermore, the toggle-type locking mechanism 6 includes a locking wrench 61, a limiting seat 62 that is positioned on the top of the clamping plate 4, and a pull rod shaft 63 that passes through the limiting seat 62, the clamping plate 4, and the arc-shaped slide 5 and extends into the first frame fixing seat 3. One end of the pull rod shaft 63 is hinged to the locking wrench 61, and the other end of the pull rod shaft 63 extends to a boss 9 with a locking rod 8 on the side. The first frame fixing seat 3 has a clearance boss 9 and a clearance groove 10 for the locking rod 8. The bottom surface of the arc-shaped slide 5 has multiple arc-shaped locking grooves 11 for locking with the locking rod 8. In use, pull the locking wrench 61 upward to move the pull rod shaft 63 downward, causing the boss 9 with the locking rod 8 to move downward, thus releasing the locking rod 8 from the locking groove 11, and thus adjusting the arc-shaped slide 5; pull the locking wrench 61 downward to move the pull rod shaft 63 upward, causing the boss 9 with the locking rod 8 to move upward, thus locking the locking rod 8 from the locking groove 11, thus locking the arc-shaped slide 5 and preventing it from loosening.

[0021] Furthermore, the toggle locking mechanism 6 also includes a first return spring 64 sleeved on the pull rod shaft 63 and clamped between the boss 9 and the clamping plate 4; the top of the clamping plate 4 is provided with an insert groove 12, the bottom surface of the insert groove 12 is recessed with a limiting groove 13, and the bottom of the limiting seat 62 extends with a limiting post 14 that cooperates with the limiting groove 13 to prevent the limiting seat 62 from rotating.

[0022] Furthermore, the first frame fixing seat 3 has a spring mounting groove 15 near the locking rod 8. The toggle locking mechanism 6 also includes a second return spring 65 inserted into the spring mounting groove 15 and a damping ball 66 disposed on the top of the second return spring 65 for abutting against the locking groove 11, so as to prevent the arc-shaped slide 5 from sliding easily and being difficult to position. Moreover, the spring mounting groove 15 is located near the locking rod 8 of the first frame fixing seat 3. After the damping ball 66 abuts against the locking groove 11, if the toggle locking mechanism 6 locks the arc-shaped slide 5, the locking rod 8 can also abut against the locking groove 11 and lock, which is more convenient for adjustment.

[0023] Furthermore, the first frame fixing seat 3 is provided with an arc-shaped guide rail 16, and the bottom of the arc-shaped slide seat 5 is provided with an arc-shaped slide groove 17 that is limited and matched with the arc-shaped guide rail 16.

[0024] Furthermore, the top surface of the arc-shaped slide block 5 is provided with an arc-shaped limiting guide groove 18 and an arc-shaped clearance guide groove 19, both of which are connected to the arc-shaped slide groove 17. The end of the arc-shaped guide rail 16 away from the toggle locking mechanism 6 has a protruding limiting shaft 20 for limiting and cooperating with the arc-shaped limiting guide groove 18 to prevent the arc-shaped slide block 5 from detaching from the first frame fixing seat 3. The arc-shaped clearance guide groove 19 is used to make way for the toggle locking mechanism 6. The arc-shaped clearance guide groove 19 facilitates the adjustment and movement of the arc-shaped slide block 5 to avoid interference from the toggle locking mechanism 6.

[0025] Furthermore, the arc-shaped slide block 5 protrudes from the outer arc-shaped top surface of the clamping plate 4 and is provided with multiple arc-shaped scale marks 21. The clamping plate 4 is provided with an indicator mark 22 on the side near the scale marks 21. By using fixed indicator marks 22 to correspond to multiple scale marks 21, the operator can accurately adjust the corresponding angle of the arc-shaped slide block 5 by relying on the scale marks 21.

[0026] Furthermore, the arc-shaped lock base 2 includes a second frame fixing base 23, a handle 24 hinged to the second frame fixing base 23, a latch 25 hinged to the handle 24, and a button 26 hinged to the handle 24 for controlling the opening and closing of the handle 24. The latch 25 is used to engage with the latch groove 7. When two adjacent displays are spliced, the latch 25 on one display engages with the latch groove 7 on the other display, facilitating quick splicing.

[0027] Furthermore, the first receiving groove 27 and the second receiving groove 28 are respectively provided at the first and second ends of the second frame fixing base 23. A clearance through hole 29 is connected between the first receiving groove 27 and the second receiving groove 28. The arc-shaped lock base 2 also includes a headed rod 30 that passes through the first receiving groove 27 and the clearance through hole 29 and extends into the second receiving groove 28, a limiting cap 31 fixedly connected to the tail end of the headed rod 30, and a sleeve on the headed rod 30 and clamped to the headed rod 30. The third return spring 32 is located between the first end of the handle 24 and the first receiving groove 27. The bottom of the handle 24 near the second frame fixing seat 23 has a top block 33 for pushing the head rod 30. The arc-shaped slide 5 has a limit hole 34 on the side away from the toggle locking mechanism 6. When the buckle 25 is fastened with the buckle groove 7, the top block 33 pushes the head rod 30 to make the limit cap 31 protrude out of the second receiving groove 28 and engage with the limit hole 34, which helps to improve the connection stability.

[0028] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
