In the present application, the rotation central angle of the predetermined trajectory is equal to or greater than 30 degrees and equal to or less than 50 degrees. Like this, through the rotation central angle of optimizing the predetermined orbit, and the corner scope of installation or dismantlement signal control box 20 has been injectd, that is to say, optimize the trompil radian scope of joint hole 21, avoid the rotation central angle undersize of predetermined orbit and be unfavorable for the installation or the dismantlement of signal control box 20, still avoid the rotation central angle of predetermined orbit too big simultaneously and make the distance between two adjacent joint holes 21 less, ensure that the periphery of the joint hole 21 of signal control box 20 has sufficient structural strength.

Preferably, the predetermined trajectory has a rotation central angle of 40 degrees.

It should be noted that, in the present application, as shown in fig. 2 to 8, the width of the snap-in hole 21 is gradually reduced along a predetermined trajectory and in a direction in which the signal control box 20 moves from the free movement position to the locking position. Thus, the width of the catching hole 21 at the freely moving position is larger than that at the locking position. Referring to fig. 5 and 7, when the maintenance personnel need to disassemble and maintain the signal control box 20, the maintenance personnel rotate the signal control box 20 clockwise from the locking position to the free movement position, so that the clamping column 11 is withdrawn from the clamping hole 21, and the signal control box 20 is conveniently disassembled from the installation box 10; after the maintainer accomplished the maintenance operation, when needing to install signal control box 20 on installation box 10, the maintainer corresponded joint hole 21 of signal control box 20 with joint post 11 on the installation box 10, so that joint post 11 stretches into joint hole 21, later maintainer along anticlockwise rotatory signal control box 20, in order to rotate it to the locking position by the free shift position, correspondingly, joint post 11 is by the width broad position department of joint hole 21 to the narrower position department of width of joint hole 21 removal, until the inside wall chucking of joint post 11 and joint hole 21, realize signal control box 20 and the stable erection joint of installation box 10.

As shown in fig. 3, the snap-in post 11 includes a cylindrical section 111 and a chuck section 112 connected together, and an inner wall surface of the snap-in hole 21 at a small width end thereof is an arc surface adapted to an outer wall surface of the cylindrical section 111. Thus, by arranging the clamping column 11 to include the connected cylindrical section 111 and the clamping head section 112, when the signal control box 20 is in the locking position, the clamping head section 112 can be ensured to be clamped at the small width end of the clamping hole 21 so as to effectively limit the signal control box 20, so that the signal control box 20 is prevented from falling off from the installation box body 10, and the installation reliability of the signal control box 20 is improved; in addition, the inner wall surface of the clip hole 21 at the small width end thereof is an arc surface adapted to the outer wall surface of the cylindrical section 111, so that the adaptability of the inner wall surface of the clip hole 21 at the small width end thereof to the clip hole 21 is improved.

As shown in fig. 1 to 3 and 8, the mounting box 10 includes a back plate 12 and a mounting plate 13, the mounting plate 13 is connected to the back plate 12, the plurality of clamping posts 11 are arranged on the mounting plate 13 at intervals around the ring, and the signal control box 20 has a plurality of clamping holes 21 which are matched with the plurality of clamping posts 11 in a one-to-one correspondence manner. Like this, through setting up a plurality of joint posts 11 on mounting panel 13 around annular interval, and offer on the signal control box 20 with a plurality of joint holes 21 of a plurality of joint post 11 one-to-one complex, ensure that signal control box 20 can be rotatory around a plurality of joint posts 11 of one-to-one complex through a plurality of joint holes 21, increased the connection stress point between signal control box 20 and the installation box 10 simultaneously, further promoted the installation stability of signal control box 20 on installation box 10.

It should be noted that, in the present application, a portion of the back plate 12 is recessed to form the mounting groove 121, the mounting plate 13 is a U-shaped plate disposed in the mounting groove 121, and at least a portion of the signal control box 20 is located in the mounting groove 121. Like this, mounting panel 13 is for setting up the U-shaped board in mounting groove 121, and the U-shaped board encloses into an dodge space with backplate 12 for dodge the bottom of a plurality of joint posts 11, avoid seting up the mounting hole of a plurality of joint posts 11 on backplate 12, ensure that backplate 12 has sufficient intensity, can also realize the hidden installation to signal control box 20 simultaneously, be favorable to promoting installation space utilization, realize the ultra-thin design of display screen module.

In the illustrated alternative embodiment of the present application, as shown in fig. 8, the signal control box 20 includes a box body 22 and a box cover 23 covering the box body 22, and the fastening hole 21 is formed on a surface of the box body 22 facing the side where the box body 10 is installed. Like this, directly set up joint hole 21 on the surface of box body 22, can also reduce the manufacturing difficulty of signal control box 20 when saving the consumptive material.

In an alternative embodiment of the present application, which is not shown in the drawings, a boss structure is formed on the surface of the case 22 facing the side where the case 10 is installed, and the engaging hole 21 is formed on the boss structure. Like this, through setting up the boss structure to make joint hole 21 be located the boss structure, the surface contact of the surface of seting up joint hole 21 of boss structure and mounting panel 13 has reduced the area of contact of signal control box 20 with mounting panel 13, thereby has reduced the frictional action between the two, makes maintainer be convenient for carry out the turn-knob operation to signal control box 20.
