[0002] Arc splicing technology is an important technology in the field of splicing screens. It arranges and splices multiple display screens in a certain arc to achieve a wider and more immersive visual effect.

Since the slide groove also has a great limiting effect on the angle lock block, only one screw is needed to fix the angle lock block well on the frame, and since the angle lock block is pre-positioned by using the positioning bead, there is no need to hold the angle lock block by hand to align it with the screw hole before screwing in the screw, so the installation efficiency is greatly improved.

[0004] When performing arc splicing technology, an angle is formed between two adjacent groups of LED splicing screens, but the above technical solution cannot control the formation of a specified angle between the two groups of LED splicing screens. The existing arc angle lock is in the application, and the angle range that can be locked is limited, making it difficult to adjust the angle between the splicing screens according to needs.

[0005] To this end, we propose a splicing screen angle lock. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment: A splicing screen angle lock, such as Figure 1-Figure 3As shown, it includes a splicing frame 1 and multiple groups of angle locking mechanisms 3 arranged on the back of the splicing frame 1. A mounting plate 2 is fixedly laid inside the splicing frame 1. Multiple groups of mounting holes 200 are provided on the mounting plate 2. The splicing screen is installed in the splicing frame 1 through the mounting holes 200. The side walls of the splicing frame 1 are provided with multiple groups of hooks and hook holes for splicing.

[0027] When multiple groups of splicing frames 1 are spliced, the hooks and the hook holes are used to make preliminary connections between the multiple groups of splicing frames 1. The angle locking mechanisms 3 are distributed at the corresponding corners of the splicing frames 1. When multiple groups of splicing frames 1 are horizontally laid and spliced, the horizontal splicing between the multiple groups of splicing frames 1 can be quickly completed through the cooperation of the hooks and the hook holes and the tightening of the screws. However, when an angle needs to be set between two adjacent groups of splicing frames 1, the angles of the two groups of splicing frames 1 to be spliced ​​are positioned by the angle locking mechanisms 3.

[0028] Furthermore, the angle locking mechanism 3 includes a first fixing seat 301 and a second fixing seat 302, both of which are fixedly mounted on the back of the splicing frame 1, and a spacing is set between the first fixing seat 301 and the second fixing seat 302, a sliding arm 304 is slidably mounted in the first fixing seat 301, and a screw rod 303 is internally threadedly mounted on the second fixing seat 302, an end of the screw rod 303 close to the sliding arm 304 is rotatably connected to the sliding arm 304, and an end of the screw rod 303 away from the sliding arm 304 is provided with a control handle 305, by rotating the control handle 305, the control handle 305 controls the screw rod 303 to move left and right, and the screw rod 303 will push the sliding arm 304 to move left and right, and an eccentric locking disk 306 is movably mounted on the end of the sliding arm 304 away from the screw rod 303 through a rotating shaft, and a plurality of groups of locking holes 307 are penetrated through the eccentric locking disk 306, and the plurality of groups of locking holes 307 are evenly arranged on the eccentric locking disk 306. The eccentric locking disk 306 is adjusted to overlap with each other on the two groups of splicing frames 1, and the eccentric locking disk 306 is controlled to rotate eccentrically so that the two groups of eccentric locking disks 306 close to each other form an overlapping surface, and the locking bolt 309 passes through the overlapping eccentric locking disk positioning hole 308 and the locking hole 307, thereby locking the position of the eccentric locking disk 306, and then a group of locking bolts 309 is used to pass through the locking holes 307 corresponding to the upper and lower overlapping surfaces of the two groups of eccentric locking disks 306, so as to facilitate locking of the two groups of eccentric locking disks 306 close to each other. When the two groups of splicing frames 1 are spliced ​​at an angle, the angle locking mechanism 3 is set to increase the angle range between the two groups of splicing frames 1 to be spliced.

[0029] Furthermore, an avoidance groove 4 is opened on the back of the splicing frame 1 at the position of the corresponding angle locking mechanism 3. When the two groups of splicing frames 1 only need to be spliced ​​horizontally, the sliding arm 304 is controlled to slide inward, so that the sliding arm 304 and the corresponding eccentric locking plate 306 retract inward along the avoidance groove 4 and are distributed on the rear side of the splicing frame 1, thereby facilitating the control of the two groups of splicing frames 1 to have no obstruction in the splicing surfaces with each other, and facilitating the two groups of splicing frames 1 to complete horizontal splicing.

[0030] The working principle of this utility model:

[0031] When two groups of splicing frames 1 are spliced, the angle between the two groups of splicing frames 1 is first adjusted. After adjusting to the specified angle, the extension length of the sliding arms 304 on the two groups of splicing frames 1 is controlled, and then the two groups of eccentric locking disks 306 on the two groups of splicing frames 1 that are close to each other are adjusted to overlap up and down. By controlling the eccentric locking disks 306 to rotate eccentrically, the two groups of eccentric locking disks 306 that are close to each other form an overlapping surface, and the locking bolts 309 pass through the overlapping eccentric locking disk positioning holes 308 and locking holes 307, thereby locking the positions of the eccentric locking disks 306. Then, a group of locking bolts 309 is used to pass through the locking holes 307 corresponding to the upper and lower overlapping surfaces of the two groups of eccentric locking disks 306, so as to facilitate locking of the two groups of eccentric locking disks 306 that are close to each other. When the two groups of splicing frames 1 are spliced ​​at an angle, the angle range between the two groups of splicing frames 1 to be spliced ​​is increased by the angle locking mechanism 3 that is set.

[0032] When the two groups of splicing frames 1 only need to be spliced ​​horizontally, the sliding arm 304 is controlled to slide inward, so that the sliding arm 304 and the corresponding eccentric locking plate 306 retract inward along the avoidance groove 4 and are distributed on the rear side of the splicing frame 1, thereby facilitating the control of the two groups of splicing frames 1 to have no obstruction on the splicing surfaces with each other, and facilitating the two groups of splicing frames 1 to complete horizontal splicing.
