[0002] The controller is a main command device that changes the wiring of the main circuit or control circuit and the resistance value in the circuit in a predetermined order to control the start, speed regulation, braking and reversal of the motor. It is composed of a program counter, an instruction register, an instruction decoder, a timing generator and an operation controller. It is the "decision-making body" that issues commands, that is, it coordinates and directs the operation of the entire computer system.

[0003] Controllers are divided into combinational logic controllers and microprogram controllers, each with its own strengths and weaknesses. Combinational logic controllers are difficult to design and have a complex structure. Once designed, they cannot be modified or expanded, but they are fast. Microprogram controllers are easy to design and have a simple structure. They are easy to modify or expand. To modify the function of a machine instruction, you only need to reprogram the corresponding microprogram.

[0004] When the controller is in use, the controller is installed and fixed by matching the threaded holes and threads on the mounting plate. The use angle of the fixed controller is restricted, especially when the controller is installed in a relatively small space. This makes it inconvenient to install and connect the controller with signal lines and connecting lines in different directions, which brings inconvenience to the operation and use of the controller.

[0005] Therefore, a controller is urgently needed to solve the above problems. Utility Model Content

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.

[0021] See also Figure 1-4 The utility model provides a controller, including a controller body 101 and a mounting plate 102 arranged below the controller body 101, the mounting plate 102 is provided with a threaded hole 103 for installing the controller body 101, and also includes a sleeve 2 fixed at the lower end of the controller body 101, and an adjustment limit component is provided between the sleeve 2 and the mounting plate 102 for using an angle adjustment limit after the controller body 101 is threadedly installed.

[0022] The adjustment and limiting assembly includes a mounting cavity 301 disposed inside the sleeve 2, a conical groove 302 is provided on the inner wall of the mounting cavity 301, a limiting rod 303 is connected to the mounting cavity 301 through a connecting assembly and a pulling assembly, and a conical surface 304 matching the conical groove 302 is provided on the outer side of the limiting rod 303;

[0023] It should be noted here that: by adjusting the limit assembly, the use angle of the controller body 101 after threaded installation is adjusted and limited, so that the controller body 101 can still be used at different use angles after installation, which facilitates the quick connection and disassembly of the controller body 101 with signal lines and connecting lines at different positions, and facilitates the operation and use of the controller body 101.

[0024] The pulling assembly includes a rotating circular plate 401, which is rotatably connected to the inside of the installation cavity 301 through the rotating assembly. The rotating circular plate 401 and one end of the limiting rod 303 located inside the installation cavity 301 are connected to a pulling spring 402. The conical surface 304 on the limiting rod 303 is set against the conical groove 302 under the pulling action of the pulling spring 402.

[0025] It should be noted here that: after the use angle adjustment of the controller body 101 is completed, the pulling spring 402 on the pulling assembly pulls the rotating circular plate 401, the sleeve 2 and the controller body 101, so that the controller body 101 is reset toward the mounting plate 102. During the reset movement of the controller body 101, the conical groove 302 on the sleeve 2 is abutted against the conical surface 304 on the limit rod 303.

[0026] The connecting assembly includes a sleeve 501 fixed on the rotating circular plate 401, a slide rod 502 is slidably connected to the sleeve 501, the other end of the slide rod 502 is fixed to the upper end of the limit rod 303, and the pull spring 402 is sleeved on the outer side of the sleeve 501 and the slide rod 502;

[0027] It should be noted here that: during the movement of the sleeve 2, the slide bar 502 is driven to slide on the sleeve 501 under force, and the sliding of the slide bar 502 on the sleeve 501 facilitates the stable pulling of the sleeve 2.

[0028] The rotating assembly includes a mounting groove 601 provided inside the mounting cavity 301, an annular groove 602 is provided on the inner wall of the mounting groove 601, an annular plate 603 is rotatably connected to the annular groove 602, and the annular plate 603 is fixed to the outer side of the rotating circular plate 401;

[0029] It should be noted here that the annular groove 602 and the annular plate 603 facilitate the rotational connection between the rotating circular plate 401 and the mounting cavity 301 .

[0030] The conical groove 302 and the conical surface 304 are provided with anti-slip protrusions;

[0031] It should be noted here that: by providing the anti-slip protrusion, the friction force between the conical groove 302 and the conical surface 304 is increased, thereby improving the limiting effect of the controller body 101 after rotation adjustment.

[0032] Working principle: When the controller is in use, in order to facilitate the stable operation of the controller, the mounting plate 102 and the controller are limitedly installed through the cooperation between the multiple threaded holes 103 and the bolts;

[0033] After the controller is installed, in order to facilitate the connection of the controller with signal lines and connecting lines at different positions, the use angle of the controller is adjusted. During the adjustment process, the controller body 101 is pulled away from the mounting plate 102. During the pulling process, the conical groove 302 on the sleeve 2 is no longer against the conical surface 304 of the limit rod 303. After the pulling is completed, the controller body 101 is rotated. By rotating the controller body 101, the use angle of the controller body 101 is adjusted;

[0034] After the use angle adjustment of the controller body 101 is completed, the pulling spring 402 on the pulling assembly pulls the rotating circular plate 401, the sleeve 2 and the controller body 101, so that the controller body 101 is reset toward the mounting plate 102. During the reset movement of the controller body 101, the conical groove 302 on the sleeve 2 is abutted against the conical surface 304 on the limiting rod 303. The abutment between the conical groove 302 and the conical surface 304 limits the rotation-adjusted controller body 101, and the angle of the controller body 101 after rotation is kept stable for use, so that the controller body 101 can still be used at different use angles after installation, which facilitates the quick connection and disassembly of the controller body 101 with signal lines and connecting lines at different positions, and facilitates the operation and use of the controller body 101.
