DETAILED DESCRIPTION

[0028] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in one embodiment, a lifting connection structure 100 is provided, including a first lifting lock module 110 and a second lifting lock module 120. The first lifting lock module 110 includes a first connecting member 111, and a locking portion 1111 is provided at one end of the first connecting member 111. The second hanging lock module 120 includes a second connecting member 121 and a locking member 122. The second connecting member 121 is provided with a mounting through hole 1211. The locking member 122 can be movably installed in the mounting through hole 1211. The locking member 122 is provided with a locking cavity 1222 with a first opening 1221 at one end close to the locking portion 1111. When the locking member 122 is in a released state, along the axial direction of the first opening 1221, the projection area of ​​the locking portion 1111 is located within the projection area of ​​the first opening 1221, so that the locking portion 1111 can extend into or move out of the locking cavity 1222. When the locking member 122 is in a locked state, along the axial direction of the first opening 1221, the projection area of ​​the locking portion 1111 is partially located outside the projection area of ​​the first opening 1221, so that the locking portion 1111 can be locked in the locking cavity 1222.

[0030] When the hoisting connection structure 100 in the above embodiment is used, the first connection member 111 and the second connection member 121 are respectively installed on the two connection bodies 130. When the two connection bodies 130 need to be connected as one, first, the two connection bodies 130 are placed correspondingly so that the first connection member 111 and the locking member 122 are correspondingly arranged. Then, the locking member 122 is driven to move relative to the second connection member 121 so that along the axial direction of the first opening 1221, the projection area of ​​the locking portion 1111 is located within the projection area of ​​the first opening 1221, ensuring that the locking portion 1111 can extend into or move out of the locking cavity 1222. Finally, after the locking portion 1111 is extended into the locking cavity 1222, the locking member 122 is driven again to move relative to the second connecting member 121, so that along the axial direction of the first opening 1221, the projection area of ​​the locking portion 1111 is partially located outside the projection area of ​​the first opening 1221, so that the locking portion 1111 can be locked in the locking cavity 1222, so that the first connecting member 111, the locking member 122 and the second connecting member 121 can cooperate to connect the two connecting bodies 130 into one. Compared with the threaded quick connection lock in the prior art, the present application locks the locking portion 1111 in the locking cavity 1222 by means of the locking portion 1111 and the inner wall of the locking member 122 to limit the position, thereby ensuring that the locking portion 1111 cannot pass through the first opening 1221 to move out of the locking cavity 1222 when the locking member 122 is in the locked state, thereby avoiding the problem of the locking member 122 falling off due to fatigue failure of the thread, and improving the reliability of the lifting connection structure 100.

[0031] Specifically in this embodiment, the cross section of the locking cavity 1222 perpendicular to its own axis is a full circle, and the cross section of the first opening 1221 perpendicular to its own axis is a non-full circle. The inner contour of the first opening 1221 is adapted to the outer contour of the locking portion 1111. The outer side wall of the locking portion 111 includes arc surfaces arranged opposite to each other, and both arc surfaces are slidably matched with the inner side wall of the locking cavity 1222.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, further, the hoisting connection structure 100 also includes a connection body 130, the first connection member 111 is fixed on the connection body 130, and the second hanging lock module 120 also includes a third connection member 123, and the third connection member 123 is sleeved on the second connection member 121 and is used to fix the second connection member 121 on the connection body 130. In this way, each connection body 130 is provided with a first hanging lock module 110 and a second hanging lock module 120, so that two adjacent connection bodies 130 can be connected as a whole through the first hanging lock module 110 and the second hanging lock module 120, so as to realize the rapid splicing and assembly of multiple connection bodies 130.

[0033] The connection body 130 may be configured as a connection frame or a box. The first connection member 111 may be installed on the top of the connection body 130 by plugging, snapping, screwing or other fixed connection methods. The third connection member 123 may be installed on the bottom of the connection body 130 by plugging, snapping, screwing or other fixed connection methods to correspond to the second connection member 121.

[0034] like Figure 4 and Figure 5 As shown, optionally, the third connecting member 123 is provided with a stepped hole 1231, and the second connecting member 121 is provided with a flange 1212 at one end close to the connecting body 130, and the flange 1212 is located in the stepped hole 1231, so that the stepped surface 1232 of the stepped hole 1231 can cooperate with the connecting body 130 to clamp and fix the flange 1212. In this way, the second connecting member 121 can be fixed to the connecting body 130 through the third connecting member 123, thereby improving the convenience of hoisting the connecting structure 100.

[0035] Specifically in this embodiment, the second connecting member 121 can be configured as a hanging lock seat, the third connecting member 123 can be configured as a mounting cover plate, and the locking member 122 can be configured as a hanging lock pull pin.

[0036] like Figure 4 and Figure 5As shown, in one embodiment, the inner wall of the installation through hole 1211 is provided with an internal thread 1213, and the outer wall of the locking member 122 is provided with an external thread 1223, and the internal thread 1213 is threadedly connected with the external thread 1223. In this way, the locking member 122 can perform a spiral climbing action in the installation through hole 1211 through the external thread 1223 and the internal thread 1213, so that the locking member 122 can move along its own axis relative to the locking portion 1111, ensuring that the side of the locking cavity 1222 provided with the first opening 1221 can be in contact with the locking portion 1111 to tighten the two adjacent connection bodies 130, thereby improving the reliability of the hoisting connection structure 100.

[0037] Specifically in this embodiment, the connection body 130 blocks one end of the installation through hole 1211, and the inner diameter of the other end of the installation through hole 1211 is smaller than the outer diameter of the locking member 122. In this way, when a thread failure occurs between the internal thread 1213 and the external thread 1223, the connection body 130 can cooperate with the second connection member 121 to limit the locking member 122, ensuring that the locking member 122 will not fall out of the installation through hole 1211 directly, avoiding the connection body 130 from falling suddenly, and improving the reliability and safety of the hoisting connection structure 100.

[0038] like Figure 4 and Figure 5 As shown, in one embodiment, the second hanging lock module 120 further includes an operating member 124, which is located at one end of the locking member 122 away from the first connecting member 111, and the operating member 124 is in transmission connection with the locking member 122, and is used to receive the torque that causes the locking member 122 to rotate relative to the second connecting member 121. In this way, the locking member 122 can be driven by the operating member 124 to perform a spiral climbing action in the installation through hole 1211, so as to move the locking member 122 to a locked state, and the locking member 122 is in a position that contacts the inner wall of the side of the locking cavity 1222 provided with the first opening 1221, thereby improving the convenience of the hanging connection structure 100.

[0039] The operating member 124 may be configured as an operating knob, an operating handle or other operating structures.

[0040] like Figure 4 and Figure 5As shown, optionally, the inner wall of the locking cavity 1222 away from the first opening 1221 is provided with a second opening 1225, the operating member 124 is provided with a first threaded hole 1242, and the second hanging lock module 120 further includes a gasket 125 and a first screw 126, the gasket 125 is located in the locking cavity 1222, and is limitedly matched with the inner wall of the locking cavity 1222 on the side where the second opening 1225 is provided, the gasket 125 is provided with a connecting hole 1251 corresponding to the second opening 1225, and the first screw 126 passes through the connecting hole 1251 and the second opening 1225 and is threadedly connected with the first threaded hole 1242, so as to lock and fix the locking member 122 and the operating member 124. In this way, the locking member 122 can be fixed as a whole with the operating member 124 through the cooperation of the first bolt and the gasket 125, ensuring that the locking member 122 can rotate synchronously with the operating member 124, thereby improving the reliability of the hanging connection structure 100.

[0041] like Figure 4 and Figure 5 As shown, optionally, one of the two surfaces of the operating member 124 and the locking member 122 that are matched with each other is provided with a limiting boss 1241, and the other is provided with a limiting groove 1224, and the limiting boss 1241 is limitedly matched with the limiting groove 1224. In this way, the contact area between the operating member 124 and the locking member 122 is increased, ensuring that the operating member 124 can drive the locking member 122 to perform a spiral climbing action in the installation through hole 1211, thereby improving the reliability of the hoisting connection structure 100.

[0042] The number of the limiting bosses 1241 and the limiting grooves 1224 can be flexibly adjusted according to the actual use requirements. Specifically in this embodiment, at least two limiting grooves 1224 are provided on the side of the locking member 122 close to the operating member 124, and each limiting groove 1224 is arranged at intervals around the axis of the locking member 122. At least two limiting bosses 1241 are provided on the side of the operating member 124 close to the locking member 122, and each limiting boss 1241 is arranged corresponding to each limiting groove 1224.

[0043] like Figure 4 and Figure 5 As shown, in one embodiment, a limiting portion 1214 is provided at one end of the second connecting member 121 close to the operating member 124, and the second hanging lock module 120 further includes a locking assembly 127, which is mounted on the operating member 124 and can selectively lock with the limiting portion 1214. In this way, when the locking member 122 is in a locked state, the operating member 124 can be locked as a whole with the second connecting member 121 through the locking assembly 127 and the limiting portion 1214, effectively limiting the rotation of the operating member 124 and improving the reliability of the hanging connection structure 100.

[0044] like Figure 4 and Figure 5As shown, optionally, the limiting portion 1214 is provided with at least one tooth groove 1215, each tooth groove 1215 is arranged along the circumferential direction of the second connecting member 121, and each tooth groove 1215 includes a first side surface and a second side surface arranged at an angle, and the locking assembly 127 includes a button tongue 1271 and a tension spring 1272, and the button tongue 1271 can be rotatably installed on the operating member 124, one end of the tension spring 1272 is connected to the operating member 124, and the other end is connected to the button tongue 1271, so that the button tongue 1271 can be inserted into the tooth groove 1215 and cooperate with the first side surface and the second side surface in a limiting manner. In this way, the button tongue 1271, the tension spring 1272 and the tooth groove 1215 can cooperate to form a ratchet structure, which can realize the function of rotating the operating member 124 in one direction to lock two adjacent connection bodies 130, and the ratchet structure will not be stuck, the operation is simple and efficient, and it can cope with some scenes with narrow construction space, improving the practicality of the lifting connection structure 100. In addition, the ratchet structure can also provide feedback on the locking state of the operating member 124, that is, the user can judge whether the operating member 124 is in a locked state by whether the button tongue 1271 is stuck in the tooth groove 1215, thereby improving the operating experience of the lifting connection structure 10.

[0045] Specifically in this embodiment, the tooth groove 1215 can be set as a V-shaped tooth opening, and the first side surface and the second side surface are set at 90 degrees. The limiting portion 1214 is set to offset the central axis of the cylinder, so that the button tongue 1271 can be unlocked and escaped from the V-shaped tooth opening. Each V-shaped tooth opening is correspondingly set on the outer side wall of one side of the offset cylindrical central axis. The button tongue 1271 and the tension spring 1272 are correspondingly set on the side of the offset cylindrical central axis where the V-shaped tooth opening is provided.

[0046] like Figure 1 and Figure 2 As shown, in one embodiment, a first mounting hole is provided at one end of the connecting body 130, and the first connecting member 111 is configured as a hanging lock column. An end of the hanging lock column away from the locking portion 1111 extends from the body into the first mounting hole, and is limitedly matched with the first mounting hole along the circumferential direction of the hanging lock column. A second threaded hole is provided at one end of the hanging lock column away from the locking portion 1111, and the first hanging lock module 110 also includes a second screw 112, which extends into the first mounting hole and is threadedly connected to the second threaded hole, so that the connecting body 130 and the hanging lock column are fixed as a whole.

[0047] Specifically in this embodiment, a second mounting hole is provided at one end of the connection body 130 away from the first mounting hole, the first mounting hole on the connection body 130 is arranged correspondingly to the second mounting hole on the adjacent connection body 130, the hanging lock column includes a limiting section 1112 and a cylindrical section 1113, the limiting section 1112, the cylindrical section 1113 and the locking portion 1111 are connected in sequence, when the locking member 122 is in a locked state, the limiting section 1112 extends into the second mounting hole correspondingly, and cooperates with the second mounting hole in a limiting manner along the circumferential direction of the limiting section 1112, and the cylindrical section 1113 passes through the mounting through hole 1211 and the first opening 1221. In this way, the hanging lock column can limit the relative rotation between two adjacent connection bodies 130, thereby improving the reliability and convenience of the hanging connection structure 100.

[0048] In one embodiment, a display screen is provided, comprising the hanging connection structure 100 in any one of the above embodiments.

[0049] When the display screen in the above embodiment is used, the first connecting member 111 and the second connecting member 121 are respectively installed on the two connecting bodies 130. When the two connecting bodies 130 need to be connected as one, first, the two connecting bodies 130 are placed correspondingly so that the first connecting member 111 and the locking member 122 are arranged correspondingly. Then, the locking member 122 is driven to move relative to the second connecting member 121 so that along the axis direction of the first opening 1221, the projection area of ​​the locking portion 1111 is located within the projection area of ​​the first opening 1221, ensuring that the locking portion 1111 can extend into or move out of the locking cavity 1222. Finally, after the locking portion 1111 is extended into the locking cavity 1222, the locking member 122 is driven again to move relative to the second connecting member 121, so that along the axial direction of the first opening 1221, the projection area of ​​the locking portion 1111 is partially located outside the projection area of ​​the first opening 1221, so that the locking portion 1111 can be locked in the locking cavity 1222, so that the first connecting member 111, the locking member 122 and the second connecting member 121 can cooperate to connect the two connecting bodies 130 into one, so as to facilitate the hanging of the display screen. Compared with the threaded quick-connect lock in the prior art, the present application locks the locking portion 1111 in the locking cavity 1222 by means of a limiting contact between the locking portion 1111 and the inner wall of the locking member 122, thereby ensuring that the locking portion 1111 cannot pass through the first opening 1221 to move out of the locking cavity 1222 when the locking member 122 is in a locked state, thereby avoiding the problem of the locking member 122 falling off due to fatigue failure of the thread, and improving the reliability of the display screen.

[0050] Specifically in this embodiment, there are at least two hanging connection structures 100 , and two adjacent connection bodies 130 can be connected as one through the first hanging lock module 110 and the second hanging lock module 120 .
