The angle can be adjusted between them. Compared with the arc lock in the prior art, the angle adjustment member of the connecting mechanism provided by the present application does not need to be matched with the connecting seat as a whole.

[0032] As described in the background technology, with the rapid development of the LED industry, the rental business of LED display screens is also increasing. In order to meet the needs of different usage scenarios, the rental LED display screen needs to be able to display in an arc shape. The arc display of the rental LED display screens on the market is mostly achieved by splicing two adjacent display boxes using an arc lock. The existing arc lock generally includes an arc lock body and a shell provided with an arc cavity, wherein the lock body and the shell are respectively fixedly connected to the two adjacent display boxes, and the arc lock body is movably mounted on the shell through cooperation with the arc cavity, so that the angle between the two display boxes respectively connected to the lock body and the shell can be adjusted. However, since the lock body of the existing arc lock needs to cooperate with the arc cavity as a whole, therefore, in order to enable the lock body to move smoothly in the arc cavity and reduce the processing cost of the lock body and the arc cavity, the existing arc lock often leaves a large matching gap between the lock body and the arc cavity, which causes the arc lock to shake easily during the angle adjustment process.

[0033] See also Figures 1 to 7As shown, in order to solve the above-mentioned problem, according to one aspect of the present application, an embodiment of the present application provides a connecting mechanism, which is used to connect two adjacent display boxes 30 and adjust the angles of the two adjacent display boxes 30.

For angle adjustment, compared with the arc lock in the prior art, the angle adjustment member 22 of the connecting mechanism provided in this embodiment does not need to be matched with the connecting seat 21 as a whole, so the matching gap between the angle adjustment member 22 and the connecting seat 21 (that is, the matching gap between the first arc-shaped limiting structure and the second arc-shaped structure) can be set smaller, thereby effectively avoiding the shaking of the connecting mechanism during the angle adjustment process, and can also effectively reduce the processing cost of the connecting mechanism. In addition, the connecting mechanism provided in this embodiment can also set the arc centers of the first arc-shaped limiting structure and the second arc-shaped limiting structure to coincide with the intersection line of the display surfaces of the two adjacent display boxes 30, so that the angle between the display surfaces on the two adjacent display boxes 30 can correspond to the adjustment angle of the connecting mechanism, thereby improving the angle adjustment effect of the connecting mechanism provided in this embodiment on the display box 30.

[0042] In a specific embodiment, the locking member 231 in this embodiment is provided with a first threaded mounting structure, and the connecting seat 21 is provided with a first threaded mounting hole, the position of the first threaded mounting hole corresponds to the position of the angle adjustment member 22, and the locking member 231 is movably mounted on the connecting seat 21 through the cooperation between the first threaded mounting structure and the first threaded mounting hole. By providing the first threaded mounting structure on the locking member 231 provided in this embodiment and providing the first threaded mounting hole on the connecting seat 21, the locking member 231 provided in this embodiment can be movably mounted on the connecting seat 21 through the cooperation between the first threaded mounting structure and the first threaded mounting hole. At the same time, since the locking member 231 provided in this embodiment is movably mounted on the connecting seat 21 through the cooperation between the first threaded mounting structure and the first threaded mounting hole, the connecting mechanism provided in this embodiment can adjust the position of the locking member 231 relative to the connecting seat 21 by screwing the locking member 231, and then adjust the relative position of the locking member 231 relative to the angle adjustment member 22, so that the locking member 231 provided in this embodiment can be switched between the first state and the second state.

[0043] In a specific embodiment, one of the first driving structure 2311 and the second driving structure in this embodiment is a driving protrusion, and the other of the first driving structure 2311 and the second driving structure is a driving recess, and the driving protrusion is matched with the driving recess. When the driving member 232 is in a driving state, the driving protrusion is inserted into the driving recess so that the locking member 231 is driven and connected with the driving member 232. By setting one of the first driving structure 2311 and the second driving structure provided in this embodiment as a driving protrusion, and setting the other of the first driving structure 2311 and the second driving structure as a driving recess, and making the driving protrusion match with the driving recess, the locking member 231 and the driving member 232 provided in this embodiment can be driven and connected through the cooperation of the driving protrusion and the driving recess.

[0044] In an optional embodiment, the driving recess provided in this embodiment is a hole with a polygonal cross section, and the driving protrusion is a shaft with a polygonal cross section.

[0046] See also Figure 7As shown, in order to enable the driving member 232 provided in this embodiment to maintain the driving state without being acted upon by external forces, the locking assembly 23 in this embodiment further includes an elastic reset member 233, which is arranged on the locking member 231 and abuts against the driving member 232, and is used to apply elastic force to the driving member 232, so that the driving member 232 can maintain the driving state through the elastic force when the driving member 232 is not acted upon by external forces.

[0047] See also Figures 3 to 7 As shown, in a specific embodiment, the driving member 232 provided in this embodiment is a driving handle, and the driving handle provided in this embodiment is movably mounted on the locking member 231. When the rotation space of the driving handle provided in this embodiment is limited and cannot be fully rotated, the driving handle is used to screw the locking member 231. At this time, after the driving handle is rotated to a certain position, it will interfere with the connecting seat 21. At this time, the driving component can be set to an avoidance state. Because the driving connection between the driving handle and the locking member 231 is disconnected when the driving component is in the avoidance state, rotating the driving handle will not move the locking member 231. When the driving component is in the avoidance state, the driving handle can be adjusted to a position where it does not interfere with the connecting seat 21. When the driving handle is adjusted into place, the driving component can be set to the driving state. At this time, the locking member 231 can continue to be screwed by the driving handle, thereby avoiding the problem that the locking member 231 cannot be screwed due to the interference between the driving handle and the connecting seat 21.

At the same time, since the angle adjustment member 22 provided by the present embodiment is movably installed on the connection seat 21 through the cooperation of the first arc-shaped limiting structure and the second arc-shaped limiting structure, the first connection part 10 connected to the angle adjustment member 22 can be adjusted in angle relative to the connection seat 21 through the angle adjustment member 22, thereby making the connection through the connection mechanism provided by the present embodiment The angle between the two adjacent display boxes 30 connected can be adjusted. Compared with the arc lock in the prior art, the angle adjustment member 22 of the connecting mechanism provided in this embodiment does not need to be matched with the connecting seat 21 as a whole. Therefore, the matching gap between the angle adjustment member 22 and the connecting seat 21 (that is, the matching gap between the first arc-shaped limiting structure and the second arc-shaped structure) can be set to be smaller, thereby effectively avoiding the shaking of the connecting mechanism during the angle adjustment process, and can also effectively reduce the processing cost of the connecting mechanism. In addition, the connecting mechanism provided in this embodiment can also set the arc centers of the first arc-shaped limiting structure and the second arc-shaped limiting structure to coincide with the intersection line of the display surfaces of the two adjacent display boxes 30, so that the angle between the display surfaces on the two adjacent display boxes 30 can correspond to the adjustment angle of the connecting mechanism, thereby improving the angle adjustment effect of the connecting mechanism provided in this embodiment on the display box 30.
