[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figures 1 to 8 As shown, this embodiment of the invention provides an angle-adjustable lock, which includes a first connecting component 10 and a second connecting component 20. The first connecting component 10 includes a first connecting seat 11 and a plurality of first limiting structures 12. The first connecting seat 11 has an arc-shaped surface, and the plurality of first limiting structures 12 are disposed on the arc-shaped surface and spaced apart along its extension direction. A first fixing surface 112 is provided on the front side of the first connecting seat 11. The second connecting component 20 includes a second connecting seat 21 and an arc-shaped rotating rod 22. A second fixing surface 211 is provided on the front side of the second connecting seat 21. The curvature of the arc-shaped rotating rod 22 is related to the arc shape. The surfaces have the same curvature. The first end of the arc-shaped rotating rod 22 is hinged to the second connecting seat 21. The second end of the arc-shaped rotating rod 22 is provided with a second limiting structure 23. The arc-shaped rotating rod 22 is rotated with its first end as the fulcrum so that the arc-shaped rotating rod 22 can be in the connection position where its inner arc surface is close to the arc surface, and in the storage position where its inner arc surface is close to the second connecting seat 21. When the arc-shaped rotating rod 22 is in the connection position, the second limiting structure 23 can selectively cooperate with different first limiting structures 12 to adjust the angle between the first fixed surface 112 and the second fixed surface 211.

[0037] The first connecting assembly 10 and the second connecting assembly 20 of the angle adjustment lock are used to be respectively installed at the rear side of two adjacent LED display units 30, and specifically connected with the rear surface of the two LED display units 30 through the first fixing surface 112 and the second fixing surface 211 respectively. Therefore, the "front side" of some structures of the angle adjustment lock mentioned herein refers to the side of the structure facing the LED display unit 30 after the angle adjustment lock is installed at the rear of the LED display unit 30. In addition, "curvature" is used to represent the bending degree of the arc-shaped structure.

[0038] According to the technical scheme of the present application, the angle adjustment lock includes the first connecting assembly 10 and the second connecting assembly 20, and the first connecting assembly 10 and the second connecting assembly 20 are respectively installed on two adjacent LED display units 30. When it is necessary to adjust the angle between the two LED display units 30, the arc-shaped rotating rod 22 is operated to flip relative to the second connecting seat 21 with the first end as the fulcrum, and the arc-shaped rotating rod 22 is switched from the storage position to the connecting position. At this time, the inner arc surface of the arc-shaped rotating rod 22 is close to the arc surface, that is, the arc-shaped rotating rod 22 and the arc surface bend in the same direction. Then, the second limiting structure 23 at the second end of the arc-shaped rotating rod 22 is located at a proper position to limit and cooperate with one or more first limiting structures 12, so that the angle between the first fixing surface 112 and the second fixing surface 211 reaches a preset angle, and the angle between the two adjacent LED display units 30 reaches a preset angle. Compared with the way of adjusting the angle between two adjacent LED display units 30 by using the angle adjustment lock in the related art, the present application has the advantage of simple operation.

[0039] The first end of the arc-shaped rotating rod 22 is hingedly connected with the second connecting seat 21, and the axis around which the arc-shaped rotating rod 22 flips can be perpendicular to the extension direction of the arc-shaped rotating rod 22 or parallel to the extension direction of the arc-shaped rotating rod 22. Specifically, taking the arc-shaped rotating rod 22 as an example, when the arc-shaped rotating rod 22 is switched from the storage position to the connecting position, the arc-shaped rotating rod 22 is flipped backward around the first end as the fulcrum, and then the arc-shaped rotating rod 22 is rotated around the fulcrum. Then, the arc-shaped rotating rod 22 is flipped forward around the fulcrum, so that the inner arc surface of the arc-shaped rotating rod 22 is close to the arc surface, so that the second limiting structure 23 selectively limits and cooperates with the first limiting structure 12. Figure 4 When the arc-shaped rotating rod 22 is switched from the connecting position to the storage position, the arc-shaped rotating rod 22 is flipped backward around the fulcrum, and then the arc-shaped rotating rod 22 is rotated around the fulcrum. Then, the arc-shaped rotating rod 22 is flipped forward around the fulcrum, so that the inner arc surface of the arc-shaped rotating rod 22 can be close to the second connecting seat 21, facilitating storage.

[0040] It should be noted that the first limiting structure 12 can be arranged on the outer surface of the first connecting seat 11, or the first limiting structure 12 can be arranged in the first connecting seat 11. When the first limiting structure 12 and the second limiting structure 23 are limited and matched, the first limiting structure 12 is exposed. Preferably, the arc-shaped rotating rod 22 can freely rotate with the first end as the fulcrum.

[0041] The first connecting seat 11 comprises a first plate body and a first arc-shaped seat body connected with each other, the first fixed surface 112 is arranged on the first plate body, the curvature of the first arc-shaped seat body is the same as the curvature of the arc-shaped rotating rod 22, and the first limiting structure 12 is arranged on the first arc-shaped seat body. The second connecting seat 21 comprises a second plate body and a second arc-shaped seat body connected with each other, the second fixed surface 211 is arranged on the second plate body, and the arc-shaped rotating rod 22 is hingedly arranged on the second arc-shaped seat body.

[0042] As shown in Figure 2 and Figure 4 , the arc-shaped rotating rod 22 comprises a spherical part 222 and an arc-shaped rod body part 223 connected with each other, the second connecting seat 21 has a spherical groove 212 and an arc-shaped receiving groove 213 connected with each other, the spherical groove 212 is located on the side of the arc-shaped receiving groove 213 facing the first connecting seat 11, the spherical part 222 is movably arranged in the spherical groove 212, the curvature of the arc-shaped rod body part 223 is the same as the curvature of the arc-shaped receiving groove 213, and when the arc-shaped rotating rod 22 is in the receiving position, the arc-shaped rod body part 223 is at least partially located in the arc-shaped receiving groove 213. By using the above-mentioned structure of the arc-shaped rotating rod 22, the spherical part 222 can be arranged in the spherical groove 212, so that the arc-shaped rotating rod 22 is hingedly arranged on the second connecting seat 21. By using the arc-shaped receiving groove 213, the arc-shaped rod body part 223 is received, so that the arc-shaped rod body part 223 does not protrude from the second connecting seat 21.

[0043] In the embodiment, the curvature of the arc-shaped receiving groove 213 is the same as the curvature of the arc-shaped rod body part 223, and the spherical groove 212 and the arc-shaped receiving groove 213 are arranged on the second arc-shaped seat body.

[0044] As shown in Figure 2 , the second connecting seat 21 comprises a containing seat 214 and two spaced-apart pressing plates 215, the two pressing plates 215 are both arranged on the containing seat 214, the containing seat 214 and the two pressing plates 215 together enclose the spherical groove 212, the arc-shaped receiving groove 213 is arranged on the containing seat 214, and the gap between the arc-shaped receiving groove 213 and the two pressing plates 215 corresponds. By using the above-mentioned structure of the second connecting seat 21, the spherical part 222 can be limited on the containing seat 214 by the pressing plate 215, so that the spherical part 222 can move in the spherical groove 212.

[0045] The spherical groove 212 can be arranged on the accommodating seat 214, or part of the spherical groove 212 is arranged on the accommodating seat 214, and part of the spherical groove is arranged on the two pressing plates 215.

[0046] As shown in Figure 1 and Figure 2 The first limiting structure 12 includes a first limiting groove 121, and the second limiting structure 23 includes a limiting rod 231. When the arc-shaped rotating rod 22 is in the connected position, the limiting rod 231 is limitedly matched with the first limiting groove 121, and the arc-shaped cover 114 is used to press the arc-shaped rotating rod 22. The limiting mode of the first limiting groove 121 matched with the limiting rod 231 has the advantages of simple limiting structure and convenient operation.

[0047] The second end of the arc-shaped rotating rod 22 has three limiting rods 231 arranged at intervals along the extension direction of the second end. The three limiting rods 231 are respectively located in the three first limiting grooves 121. The three limiting rods 231 respectively located in the three first limiting grooves 121 can enhance the limiting effect of the first connecting seat 11 on the arc-shaped rotating rod 22.

[0048] In this embodiment, the limiting rod 231 is arranged on the opposite side of the arc-shaped rotating rod 22. The first limiting groove 121 extends to the opposite side walls of the first connecting seat 11, thereby enhancing the limiting effect of the first connecting seat 11 on the arc-shaped rotating rod 22.

[0049] Specifically, the two adjacent first limiting grooves 121 can realize the angle adjustment of 2.5° between the first fixed surface 112 and the second fixed surface 211.

[0050] As shown in Figure 1 The first connecting seat 11 includes an adjusting seat 113 and an arc-shaped cover 114. The first fixed surface 112 is arranged on the front side of the adjusting seat 113. The rear surface of the adjusting seat 113 includes an arc-shaped surface. The arc-shaped cover 114 is arranged on the rear surface of the adjusting seat 113 in an openable and closable manner. The arc-shaped cover 114 and the adjusting seat 113 together form a containing groove for containing the arc-shaped rotating rod 22. The first connecting seat 11 with the above structure can use the arc-shaped cover 114 to limit the arc-shaped rotating rod 22, so as to limit the limiting rod 231 of the arc-shaped rotating rod 22 in the first limiting groove 121, and prevent the limiting rod 231 from being pulled out of the first limiting groove 121.

[0051] The first limiting groove 121 can be arranged on the adjusting seat 113, or the first limiting groove 121 can be arranged on the arc-shaped cover 114. Part of the first limiting groove 121 can be arranged on the adjusting seat 113, and part of the first limiting groove 121 can be arranged on the arc-shaped cover 114.

[0052] In the embodiment, the curvature of the accommodating groove is the same as that of the arc-shaped rotating rod 22, and the two sides of the accommodating groove are provided with first limiting grooves 121, and the limiting rods 231 on the opposite sides of the arc-shaped rotating rod 22 are in limiting cooperation with the first limiting grooves 121 on the two sides of the accommodating groove.

[0053] Specifically, the first limiting structure 12 further comprises second limiting grooves 122, which are formed on the front surface of the arc-shaped cover 114, and correspond to the first limiting grooves 121 when the arc-shaped cover 114 is covered on the adjusting seat 113, and the limiting rods 231 are in limiting cooperation with the second limiting grooves 122. The limiting mode of cooperation between the first limiting grooves 121 and the second limiting grooves 122 can improve the limiting effect of the limiting rods 231, and make the limiting rods 231 more stable and less likely to move.

[0054] As shown in Figure 1 , one end of the arc-shaped cover 114 away from the second connecting seat 21 is hingedly connected with one end of the adjusting seat 113 away from the second connecting seat 21, and the first connecting seat 11 further comprises a locking wrench 115, which is hingedly arranged at one end of the arc-shaped cover 114 close to the second connecting seat 21, and has a locking position connected with the adjusting seat 113 and an open position separated from the adjusting seat 113. The locking wrench 115 can lock the arc-shaped cover 114 to the adjusting seat 113, thereby preventing the arc-shaped cover 114 from sliding off the adjusting seat 113, so as to prevent the arc-shaped rotating rod 22 from being separated from the adjusting seat 113.

[0055] In the embodiment, one end of the arc-shaped cover 114 is hingedly connected with the adjusting seat 113, and the other end of the arc-shaped cover 114 is locked by the locking wrench 115, thereby enabling the arc-shaped cover 114 to rotate relative to the adjusting seat 113 when the locking wrench 115 is in the open position, so that the arc-shaped rotating rod 22 is pulled out of the accommodating groove.

[0056] As shown in Figure 1 , the first connecting seat 11 further comprises a hinge shaft 116 and a torsional spring 117, the sidewall of the arc-shaped cover 114 is provided with a first hinge hole, the sidewall of the locking wrench 115 is provided with a second hinge hole penetratingly arranged, the hinge shaft 116 is inserted into the first hinge hole and the second hinge hole, and the torsional spring 117 is sleeved on the hinge shaft 116, and the two ends of the torsional spring 117 are connected with the locking wrench 115 and the arc-shaped cover 114 respectively, so as to keep the locking wrench 115 in the locking position. The torsional spring 117 can automatically switch the arc-shaped cover 114 from the open position to the locking position, which has the advantages of simple structure and easy operation.

[0057] As shown in Figure 1As shown, the front end of the locking wrench 115 is provided with a hook 1151, and the side wall of the adjusting seat 113 is provided with a clamping boss 1131, when the locking wrench 115 is in the locking position, the hook 1151 is clamped in the clamping boss 1131, and when the locking wrench 115 is in the open position, the hook 1151 is separated from the clamping boss. By using the limiting mode of clamping the hook 1151 in the clamping boss 1131, the arc-shaped cover 114 can be locked to the adjusting seat 113, which has the advantages of simple structure and easy operation.

[0058] As shown in the drawings, Figure 1 As shown, the first connecting seat 11 further comprises a filling sheet 118 arranged in the accommodating groove, and the filling sheet 118 is arranged between the side wall of the arc-shaped rotating rod 22 and the inner wall of the accommodating groove. By using the filling sheet 118, the gap between the arc-shaped rotating rod 22 and the accommodating groove can be filled, and the rotation of the arc-shaped rotating rod 22 in the accommodating groove can be prevented, so that the limiting of the first limiting groove 121 to the limiting rod 231 is more stable.

[0059] Among them, the filling sheet 118 can be attached to the adjusting seat 113, or the filling sheet 118 can be attached to the arc-shaped cover 114, as long as it can fill the gap between the arc-shaped rotating rod 22 and the accommodating groove.
