Description

Technical Field

[0001] This utility model relates to the field of controller installation technology, and in particular to a controller installation and fixing structure. Background Technology

[0002] A controller is a master control device that controls the starting, speed regulation, braking, and reversing of a motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to a predetermined sequence. Controllers are divided into combinational logic controllers and microprogram controllers. Each type of controller has its own advantages and disadvantages. The installation and fixing structure of the controller is the key part to ensure the stable and reliable operation of the controller during the working process.

[0003] Combinational logic controllers are difficult to design and have complex structures. Once the design is completed, they cannot be modified or expanded. However, they are fast. Microprogrammed controllers are easy to design and have simple structures. They are easy to modify or expand. To modify the function of a machine instruction, you only need to rewrite the corresponding microprogram. To add a machine instruction, you only need to add a microprogram to the control memory.

[0004] In existing technical solutions, the module is usually positioned on the mounting plate by hooks on the back cover and grooves on the mounting plate, and then fixed by screws. However, after the controller is fixed by drilling holes with screws, the outer shell needs to be disassembled before maintenance is required, which makes the maintenance work cumbersome and the maintenance space is limited, thus affecting the maintenance of the controller.

[0005] Therefore, a mounting and fixing structure for the controller is proposed. Utility Model Content

A second swing rod is movably connected to the front end of the first swing rod. A connecting plate is fixedly connected between the second swing rod and the operating panel.

[0009] Preferably, a torsion spring is movably connected between the first and second rocker arms, rollers are movably connected to the opposite ends of the two sliders, and a spring is fixedly connected to the rear end of the telescopic cylinder.

[0010] Preferably, the machine body has round holes at both the top and bottom ends, and a fixing component is provided inside the machine body and at the rear end. There are two fixing components, and the two fixing components are symmetrically distributed vertically. Each fixing component includes a rotating pin movably connected inside the round hole. A first bevel gear is fixedly connected to the rear end of the rotating pin, and a second bevel gear is fixedly connected to the rear end of the first bevel gear.

[0011] Preferably, the fixing component further includes a mounting base fixedly connected to the rear end of the machine body. The number of mounting bases is four, and the four mounting bases are symmetrically distributed. Each of the four mounting bases has a threaded pin movably connected inside, and a third bevel gear is fixedly connected to one end of each of the four threaded pins that is close to each other.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1 to 4 This utility model provides a technical solution:

[0029] A controller mounting and fixing structure includes a body 1, a protective sleeve 11 movably connected to the front end of the body 1, a control board 21 movably connected inside the body 1, an operation board 2 fixedly connected to the front end of the control board 21, a pull ring 22 movably connected to the outside of the operation board 2, support components 3 provided at both the upper and lower ends inside the body 1, the support components 3 including a fixed cylinder 312 fixedly connected to the upper and lower ends inside the body 1, a telescopic cylinder 311 movably connected to the outside of the fixed cylinder 312, an outer cylinder 31 movably connected to the outside of the telescopic cylinder 311, sliders 32 fixedly connected to both the left and right ends of the outer cylinder 31, grooves 321 provided at both the upper and lower ends of the sliders 32, sliding rods 33 movably connected to the ends of the two grooves 321 that are far apart from each other, a first swing rod 331 movably connected to the front end of the sliding rod 33, a second swing rod 332 movably connected to the front end of the first swing rod 331, and a connecting plate 334 fixedly connected between the second swing rod 332 and the operation board 2;

[0030] A torsion spring 333 is movably connected between the first swing arm 331 and the second swing arm 332. Rollers 322 are movably connected to the ends of the two sliders 32 that are far apart from each other. A spring 313 is fixedly connected to the rear end of the telescopic cylinder 311. The slide rod 33 slides against the inside of the slide groove 321. The roller 322 slides against the end of the first swing arm 331 that is far away from the fixed cylinder 312. The limit angle between the first swing arm 331 and the second swing arm 332 is 60 degrees. The elastic force of the torsion spring 333 is greater than the resistance of the first swing arm 331 to the roller 322. The protective sleeve 11 can be removed. The control plate 21 slides against the inside of the machine body 1.

[0031] By adopting the above technical solution, when a problem occurs during the use of the controller after it has been installed and fixed, and maintenance is required, the protective cover 11 is first removed, and then the pull ring 22 is flipped. By pulling the pull ring 22, the operating plate 2 and the control plate 21 are pulled out from the inside of the body 1. As the operating plate 2 moves forward, the connecting plate 334 at the rear end moves along with it. The connecting plate 334 moves forward, causing the second rocker arm 332 and the first rocker arm 331 inside the slider 32 to move. The first rocker arm 331 moves, causing the slide rod 33 to move inside the slide groove 321. When the first rocker arm 331 and the slide rod 33 move to the front end position inside the slide groove 321, the torsion spring 333 causes the first rocker arm 331 and the second rocker arm 332 to flip to the left and right sides of the outer cylinder 31, so that the first rocker arm 331 and the slider 32 form a 60-degree angle. At the same time, as the first rocker arm 331 continues to move, the slider 32 and the outer cylinder... The outer cylinder 31 moves together with the outer cylinder 31, which continues to move, extending the first swing rod 331 and pulling out the spring 313 at the rear end of the telescopic cylinder 311. When the control plate 21 is fully pulled out, the protruding first swing rod 331 contacts the front end of the machine body 1, making the first swing rod 331 at a 90-degree angle to the front end of the machine body 1, thus preventing the slider 32 and the outer cylinder 31 from returning to the inside of the machine body 1. At this time, maintenance work is carried out on the control plate 21. After the maintenance work is completed, the pull ring 22 is pulled, and the operating plate 2 and the control plate 21 are pulled forward and slowly pushed towards the inside of the machine body 1, so that the roller 322 presses the first swing rod 331 back to the initial position. After the slider 32, the outer cylinder 31 and other components have all returned to the inside of the machine body 1, the maintenance work on the controller is completed, so as to achieve the purpose of supporting the pulled-out control plate 21 through the support component 3, thereby facilitating the maintenance work on the control plate 21 and ensuring the stable operation of the control plate 21.

[0032] Specifically, such as Figure 4 As shown, the machine body 1 has circular holes 12 at both the top and bottom ends. A fixing component 4 is provided inside the machine body 1 and at its rear end. There are two fixing components 4, symmetrically distributed vertically. Each fixing component 4 includes a rotating pin 41 movably connected inside the circular hole 12. A first bevel gear 42 is fixedly connected to the rear end of the rotating pin 41, and a second bevel gear 421 is fixedly connected to the rear end of the first bevel gear 42. The fixing component 4 also includes four mounting seats 43 fixedly connected to the rear end of the machine body 1. These four mounting seats 43 are symmetrically distributed, and each of the four mounting seats 43 has a threaded pin 44 movably connected inside. A third bevel gear 441 is fixedly connected to one end of each of the four threaded pins 44 that is close to the other. The number of teeth on the first bevel gear 42 is twice the number of teeth on the second bevel gear 421. The third bevel gear 441 meshes with both the first bevel gear 42 and the second bevel gear 421.

[0033] By adopting the above technical solution, when installing and fixing the controller, the main body 1 and the rear-end components are first placed together in the reserved mounting hole. At this time, the rotating pin 41 inside the round hole 12 is rotated by a screwdriver. The rotating pin 41 rotates, causing the first bevel gear 42 and the second bevel gear 421 at the rear end to rotate together. The rotation of the second bevel gear 421 causes the threaded pin 44 inside the mounting base 43 to rotate through the third bevel gear 441. As the threaded pin 44 continues to enter the wall, the third bevel gear 441 moves away from the second bevel gear 421. Then, by applying force to the rotating pin 41 towards the rear end of the main body 1, the third bevel gear 441 slides to the outside of the first bevel gear 42 and fits tightly against the first bevel gear 42. After the threaded pin 44 is completely rotated and fixed into the wall, the fixing component 4 can avoid leaving holes in the wall when installing the control board 21, thereby achieving the purpose of hiding the mounting round hole and ensuring the smoothness of the mounting wall.

[0034] Working principle: First, the protective cover 11 is removed. Then, the pull ring 22 is flipped over. Pulling the pull ring 22 pulls the operation plate 2 and control plate 21 out of the machine body 1. As the operation plate 2 moves forward, it moves the connecting plate 334 at the rear end. The connecting plate 334 moves forward, causing the second rocker arm 332 and the first rocker arm 331 inside the slider 32 to move. The first rocker arm 331 moves, causing the slide rod 33 to move inside the slide groove 321. When the first rocker arm 331 and the slide rod 33 move to the front end position inside the slide groove 321, the torsion spring 333 causes the first rocker arm 331 and the second rocker arm 332 to move together. 2. The outer cylinder 31 is flipped to the left and right sides, so that the first swing rod 331 and the slider 32 form a 60-degree angle. At the same time, as the first swing rod 331 moves, it moves the slider 32 and the outer cylinder 31 together. The movement of the outer cylinder 31 continues to extend the first swing rod 331 and pull out the spring 313 at the rear end of the telescopic cylinder 311. When the control plate 21 is fully extended, the protruding first swing rod 331 contacts the front end of the machine body 1, so that the first swing rod 331 and the front end of the machine body 1 form a 90-degree angle, thereby preventing the slider 32 and the outer cylinder 31 from returning to the inside of the machine body 1. At this time, maintenance work is carried out on the control plate 21.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
