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.

[0025] Refer to the instruction manual Figure 1-6The utility model provides a touch LCD screen control terminal, comprising a control component 2 arranged at the rear end of a touch LCD screen 1, the control component 2 comprising a shell 201 and a control terminal body 202, the control terminal body 202 is fixed inside the shell 201, a sealing plate 203 is provided at the rear end of the shell 201, and a cavity 3 is provided inside the shell 201;

[0026] A connecting assembly 4 connected to the touch LCD screen 1 is provided inside the cavity 3, and the connecting assembly 4 includes a rotating rod 401, and a first bevel gear 402 is fixedly sleeved on the outer wall of the rotating rod 401, and four second bevel gears 403 are meshed on the outer wall of the first bevel gear 402, and a threaded rod 404 is fixedly penetrated inside each second bevel gear 403, and a nut block 405 is threadedly connected to the threaded rod 404, and four movable grooves 7 are opened on the outer wall of the housing 201, and the four nut blocks 405 are respectively arranged in the four movable grooves 7 for accommodating the nut blocks 405;

[0027] Next, a fixing groove 5 is provided at the rear end of the touch LCD screen 1, and four slots 6 adapted to the nut blocks 405 are provided on the inner wall of the fixing groove 5. The four nut blocks 405 are respectively inserted into the four slots 6, so as to facilitate the disassembly of the housing 201. A first gear 8 is fixedly sleeved on the rotating rod 401. The first gear 8 is arranged behind the first bevel gear 402 and the second bevel gear 403. A second gear 9 is meshed with the top of the first gear 8. A torsion bar 10 is fixedly passed through the inside of the second gear 9. The user drives the second gear 9, the first gear 8, the first bevel gear 402, and the second bevel gear 403 with the help of the torsion bar 10 to drive the four threaded rods 404 to rotate, so as to facilitate the adjustment of the positions of the four nut blocks 405.

[0028] In addition, a wire management groove 13 is opened at the front end of the shell 201, and a connector 14 is fixedly passed through the wire management groove 13. The connector 14 is connected to the control terminal body 202 and the touch LCD screen 1. When the connector 14 is connected to the connecting wire on the touch LCD screen 1, the connecting wire can be placed in the wire management groove 13.

[0029] When installing the control component 2, the user first connects the connector 14 at the rear end of the shell 201 with the connecting line on the touch LCD screen 1, then inserts the fixing slot 5 on the touch LCD screen 1, and then twists the torsion bar 10 to drive the second gear 9 to rotate. When the second gear 9 is engaged with the first gear 8, it drives the first bevel gear 402 on the rotating rod 401 to rotate. When the first bevel gear 402 is engaged with the four second bevel gears 403, the second bevel gear 403 drives the threaded rod 404 to rotate, so that the nut block 405 on the threaded rod 404 is moved out of the movable slot 7 and inserted into the slot 6, thereby completing the fixation of the shell 201 and the fixing slot 5, and loosening the torsion bar 10 in the reverse direction can make the four nut blocks 405 re-stored in the movable slot 7, so that the user can take the shell 201 out of the fixing slot 5.
