[0026] Reference Figure 1-3In one embodiment, a splicing locking device for splicing adjacent first spectator lights 1 and second spectator lights 4 includes a locking shaft structure 100. The locking shaft structure 100 includes a shaft 101 and a pin hole 102. The shaft 101 is a cylindrical structure. The shaft 101 passes through the bottom wall of the indexing pin handle 200 and the spring 300 and is fixedly connected to the fixing plate 400. Part of the fixing plate 400 is located inside the indexing pin handle 200. The fixing plate 400 is provided with a first locking block 401 and a second locking block 402. The side of the indexing pin handle 200 away from the bottom wall is open. The indexing pin handle 200 is provided with a first locking groove 201 and a second locking groove 202, and the first locking groove 201 and the second locking groove 202 are respectively connected to the open side. The opening is connected, the first slot 201 and the first block 401 cooperate, the second slot 202 and the second block 402 cooperate, the indexing pin handle 200 is provided with multiple mounting blocks 203 on the bottom wall away from the spring 300, each mounting block 203 is set one-to-one with each mounting slot 2 of the first audience light 1, the multiple mounting slots 2 form an adjustment position, the locking shaft structure 100 where the shaft 101 is located is located in the first placement cavity 3 of the first audience light 1, the locking shaft structure 100 where the pin hole 102 is located can rotate relative to the shaft 101 so that the locking shaft structure 100 where the pin hole 102 is located is located in the second placement cavity of the second audience light 4, and the pin 600 passes through the through hole of the second audience light 4 and cooperates with the pin hole 102. In use, manually move the indexing pin handle 200 toward the fixing plate 400, forcing the spring 300 to deform under compression. Since the first locking block 401 engages with the first locking groove 201 and the second locking block 402 engages with the second locking groove 202, the indexing pin handle 200 moves in a directional manner. When the mounting block 203 on the bottom wall of the indexing pin handle 200 disengages from the mounting groove 2, rotate the indexing pin handle 200 so that the fixing plate 400 and the locking shaft structure 100 also rotate. When the pin hole 102 of the locking shaft structure 100 reaches the second placement cavity of the second spectator light 4, insert the pin 600 into the through hole and pin hole 102 of the second spectator light 4, and then release the indexing pin handle 200 so that the mounting block 203 of the indexing pin handle 200 engages with the mounting groove 2 of the first spectator light 1, and the spring 300 returns to its deformed state, completing the assembly. When disassembly is required, simply pull out the pin 600 and then rotate in the opposite direction. In this embodiment, the locking shaft structure 100, the fixing plate 400, the indexing pin handle 200 and the spring 300 cooperate with each other. The rotation of the locking shaft structure 100 enables the locking shaft structure 100 with pin hole 102 to rotate relative to the shaft 101 so that the locking shaft structure 100 with pin hole 102 is located in the second placement cavity of the second audience light 4, thereby facilitating the assembly of the first audience light 1 and the second audience light 4. The structure is simple and achieves the requirement of tight assembly under the condition of small space.

[0027] Continue to refer to Figure 2Furthermore, the locking shaft structure 100 also includes a shaft block 103.

The shape of the second limiting groove matches the shape of the second bushing 105 and the second limiting groove is located on the other side of the first placement cavity.

[0029] In one embodiment, multiple mounting blocks 203 are arranged in a circle, and the adjustment position formed by multiple mounting grooves 2 is also circular. That is to say, relative to the shaft 101, the shaft block 103 and the pin hole 102 of the shaft block 103 can be rotated to different positions.

[0030] In one embodiment, there are four mounting blocks 203, so that the shaft 101 can be fixed in four different positions after rotation. Preferably, the four mounting blocks 203 are evenly arranged, that is, the angle between adjacent mounting blocks 203 and the center of the circle is 90 degrees.

[0031] Furthermore, in one embodiment, the shaft 101 and the fixing plate 400 are connected by bolts 500.

[0032] Furthermore, in one embodiment, the shaft block 103 where the pin hole 102 is located has chamfers at both ends to facilitate the insertion and removal of the pin 600, and the pin 600 and the pin hole 102 can be an interference fit.
