Description

Technical Field

[0001] This utility model relates to the field of controller installation structure technology, specifically a controller fixing structure and a controller. 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. It consists of a program counter, instruction register, instruction decoder, timing generator, and operation controller. It is the "decision-making body" that issues commands, that is, it coordinates and directs the operation of the entire computer system. Controllers are divided into combinational logic controllers and microprogrammed controllers, each with its own advantages and disadvantages. Combinational logic controllers are difficult to design and have a complex structure; once designed, they cannot be modified or expanded, but they are fast. Microprogrammed 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, only the corresponding microprogram needs to be rewritten; to add a machine instruction, only a microprogram needs to be added to the control memory, but it is done by executing a microprogram. A detailed comparison is as follows: Combinational logic controllers, also known as hardwired controllers, are composed of logic circuits and rely entirely on hardware to implement the functions of instructions.

[0003] The existing controllers are installed on the controller bracket with multiple bolts, so the disassembly and assembly of the controllers require the removal and installation of multiple screws, which makes the disassembly, assembly and maintenance of the controllers inconvenient.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] Example 1:

[0030] This utility model provides a controller fixing structure. Please refer to [link / reference]. Figure 1-6The system includes a controller 1, which has a frame 11. The frame 11 is mounted on a controller bracket 2, which serves as a support for the controller 1. Therefore, the controller bracket 2 is mounted on a corresponding device, and the frame 11 and the controller bracket 2 are fixed together by a fastener. Both the frame 11 and the controller bracket 2 have through holes for the fastener to pass through, and the end of the fastener is elastically locked onto the controller bracket 2.

[0031] The frame 11 is provided with a first through hole 111 and a first rectangular through hole 112. There are two first rectangular through holes 112, and the two first rectangular through holes 112 are symmetrical about the first through hole 111. Both first rectangular through holes 112 are connected to the first through hole 111.

[0032] The fastener includes a rod body, which is configured as a first rod body 31. The limiting plate 32 and the embedding block 34 are respectively welded to both ends of the first rod body 31. The limiting plate 32 is welded to the top end of the first rod body 31, and the embedding block 34 is welded to the other end of the first rod body 31. A spring 33 is sleeved on the rod body.

[0033] The controller bracket 2 is provided with a second through hole 21, a second rectangular through hole 22 and a rectangular groove 23. There are two of each of the second rectangular through hole 22 and rectangular groove 23. The diameter of the first rod 31 is equal to the diameter of the second rectangular through hole 22, and the diameter of the first rod 31 is equal to the diameter of the first through hole 111.

[0034] The two second rectangular through holes 22 are symmetrical about the second through hole 21, and both second rectangular through holes 22 are connected to the second through hole 21. During the process of the first rod 31 passing through the first through hole 111 and the second through hole 21, the embedded block 34 can pass through the first rectangular through hole 112 and the second rectangular through hole 22.

[0035] The two rectangular grooves 23 are symmetrical about the second through hole 21, and both rectangular grooves 23 are connected to the second through hole 21.

[0036] The rod passes through the first through hole 111 and the second through hole 21. The embedded block 34 is inserted into the rectangular groove 23. The spring 33 is in a compressed state, so that the spring 33 has the function of a top limiting plate 32, thereby the embedded block 34 is stably inserted into the rectangular groove 23.

[0037] In practical use, the frame 11 of the controller 1 is aligned and fitted with the controller bracket 2, so that the first through hole 111 is aligned with the second rectangular through hole 22. At this time, the first rectangular through hole 112 and the second rectangular through hole 22 are aligned. The embedding block 34 is passed through the first rectangular through hole 112 and the second rectangular through hole 22. At this time, the first rod 31 passes through the first through hole 111 and the second rectangular through hole 22. The first rod 31 is rotated until the embedding block 34 is aligned with the rectangular groove 23. Under the elastic force of the spring 33, the embedding block 34 enters the rectangular groove 23, thereby enabling the controller to be installed and fixed.

[0038] Example 2:

[0039] See attached document Figure 7 Unlike Embodiment 1, the rod body is composed of an internally threaded tube 311 and an internally threaded rod 312. The internally threaded tube 311 is threadedly connected to the internally threaded rod 312. The limiting plate 32 is welded to the end of the internally threaded tube 311, and the embedded block 34 is welded to the end of the internally threaded rod 312. At this time, the outer diameter of the internally threaded tube 311 is equal to the diameter of the first rectangular through hole 112 and the second rectangular through hole 22.

[0040] In practical use:

[0041] Align and fit the frame 11 of controller 1 with the controller bracket 2 so that the first through hole 111 is aligned with the second rectangular through hole 22. At this time, the first rectangular through hole 112 and the second rectangular through hole 22 are aligned. Pass the embedded block 34 through the first rectangular through hole 112 and the second rectangular through hole 22. At this time, the rod body composed of the internal thread tube 311 and the internal thread rod 312 passes through the first through hole 111 and the second rectangular through hole 22. Rotate the rod body until the embedded block 34 is aligned with the rectangular groove 23. Under the elastic force of the spring 33, the embedded block 34 enters the rectangular groove 23, thereby installing and fixing the controller. At this time, it is necessary to increase the elastic force of the spring 33. The internal thread tube 311 can be rotated so that the internal thread rod 312 is inserted more into the internal thread tube 311.

[0042] A controller is fixed and installed using the aforementioned controller fixing structure.
