Description

Technical Field

[0001] The utility model relates to the technical field related to a PLC control cabinet, in particular to a pressure-resistant structure of a PLC control cabinet. Background Art

[0002] PLC control cabinet refers to a programmable control cabinet. In order to increase the service life of the control cabinet, its pressure resistance needs to be improved. However, the existing PLC control cabinet pressure resistance structure still has certain defects when used, such as;

[0003] For example, a PLC control cabinet compression-resistant structure with publication number CN218420881U has a shock-absorbing plate arranged between the box body and the protective shell. When the box body is squeezed by external force, the shock-absorbing plate is bent by the external force, which buffers the force transmitted to the box body, reduces the deformation of the box body due to squeezing, and thus reduces damage to components in the control cabinet.

[0004] However, the PLC control cabinet pressure-resistant structure still has the following disadvantages in actual use:

[0005] By setting a shock-absorbing plate between the box body and the protective shell for buffering, in actual use, installing the shock-absorbing plate between the box body and the protective shell not only greatly increases the overall installation cost, but also when maintenance or replacement is required, the entire structure may need to be disassembled, which increases the difficulty and cost of maintenance. Moreover, if only the shock-absorbing plate is used for buffering, the shock-absorbing plate will transmit external force, resulting in poor overall stability, thereby causing damage to the internal components of the control cabinet and reducing the overall service life.

[0006] In view of the above problems, it is urgent to carry out innovative design based on the original PLC control cabinet pressure-resistant structure. Therefore, we proposed that the PLC control cabinet pressure-resistant structure can solve the above problems well. Utility Model Content

[0033] Embodiment 1:

[0034] In this embodiment, in order to improve the overall stability, the inner buffer component is used in conjunction with the outer buffer component, the purpose of which is to reduce the problem of low stability caused by using only the shock-absorbing sheet for buffering, such as Figure 1 , Figure 3 and Figure 4The technical solution shown includes a cabinet 1, which is connected to a controller 8 through an internal buffer component. The internal buffer component includes a support seat 2 installed in the cabinet 1, and a first slider 4 is connected to the inside of the support seat 2. The first slider 4 is symmetrically arranged, and a first spring 3 is connected to the inner side of the first slider 4. A tilt rod 5 is installed on the first slider 4, and a second slider 6 is arranged at the other end of the tilt rod 5. The second slider 6 is connected to the inside of a sliding seat 7, and the sliding seat 7 is installed on the controller 8. The external force is buffered by the cooperation between the first spring 3 and the tilt rod 5. An external buffer component is provided at the bottom of the cabinet 1, and the external buffer component includes a sleeve 9 installed at the bottom of the cabinet 1. A buffer member 10 is arranged inside the sleeve 9, and a support rod 11 is installed at the bottom of the buffer member 10. The support rod 11 passes through the inside of a base 14, and the base 14 is arranged at the bottom of the sleeve 9. A first pressing plate 12 is installed at the bottom of the support rod 11, and a first airbag 13 is arranged at the lower end of the first pressing plate 12. The first airbag 13 is installed in the inside of the base 14 through a support column 15, and cooperates with the first airbag 13 through the buffer member 10. Buffering is performed, and the cabinet 1 is supported by the base 14. When the cabinet 1 is subjected to external pressure, the first slider 4 inside the support seat 2 drives the first spring 3 to buffer through the cooperation of the tilting rod 5. At this time, the second slider 6 at the bottom of the tilting rod 5 slides in the sliding seat 7, so that the controller 8 is supported more stably inside the cabinet 1, reducing the damage problem caused by external pressure. The overall structure is simple and convenient for installation operation, reducing the problem of increased installation and maintenance costs caused by being set between shells, and the sleeve 9 at the bottom of the cabinet 1 is buffered by the internal buffer 10, and the buffer 10 is pressed downward by the bottom support rod 11. At this time, the first pressure plate 12 squeezes the first airbag 13 and supports it through the first airbag 13, so that the overall stability is improved, thereby greatly improving the pressure resistance of the overall cabinet 1, and the first airbag 13 is supported by the support column 15 inside the base 14, so that the overall stability is improved, reducing the problem of low stability caused by only using shock-absorbing plates for buffering, and greatly improving the overall service life.

[0035] Embodiment 2:

[0036] In this embodiment, in order to increase the overall service life, a cleaning component is provided to perform a cleaning operation, the purpose of which is to reduce the problem of reduced heat dissipation caused by clogging of the filter screen 17. Figure 2 and Figure 5As shown, heat dissipation grooves 16 are provided on both sides of the cabinet 1, and filters 17 are installed inside the heat dissipation grooves 16. A cleaning component is installed inside the cabinet 1, and the cleaning component includes an air delivery member 18 installed inside the cabinet 1. The output end of the air delivery member 18 is connected to a second air bag 20 through a hose. The second air bag 20 is installed inside a storage box 19, and the storage box 19 is installed inside the cabinet 1. The second air bag 20 is connected to the first air bag 13 through a hose. A pipe 21 is connected to the second air bag 20 through a hose. The pipe 21 is installed inside the cabinet 1. A nozzle 22 is provided on the pipe 21. The nozzle 22 is located at the side end of the heat dissipation groove 16. When the controller 8 inside the cabinet 1 is used, heat will be generated. At this time Heat is dissipated through the heat dissipation slots 16 opened on both sides of the cabinet 1, and a filter 17 is arranged inside the heat dissipation slot 16. Therefore, the filter 17 blocks dust in the external environment, reducing the problem of dust entering the cabinet 1 and causing damage to the controller 8. The air delivery piece 18 is opened to deliver gas to the second air bag 20 in the storage box 19. The second air bag 20 delivers the gas through the pipeline 21 and sprays the gas through the nozzle 22. The gas sprayed by the nozzle 22 cleans the dust on the filter 17, reducing the problem of increased labor intensity caused by the need to manually clean the filter 17, and facilitating the heat dissipation operation of the heat dissipation slot 16, greatly improving the overall service life.

[0037] Embodiment three:

[0038] In this embodiment, in order to improve the overall heat dissipation efficiency, the heat dissipation components are set to operate, the purpose of which is to reduce the problem of reduced service life due to heat influence, specifically as follows: Figure 5-Figure 7As shown, a heat dissipation component is installed inside the cabinet 1, and the heat dissipation component includes a motor 23 installed inside the cabinet 1, a rotating shaft 24 is connected to the output end of the motor 23, a fan blade 25 is sleeved on the outer side of the rotating shaft 24, an eccentric wheel 26 is sleeved on the outer side of the rotating shaft 24, and an auxiliary component is arranged on the side end of the eccentric wheel 26, and the auxiliary component includes a movable plate 27 installed on the side end of the eccentric wheel 26, a movable rod 28 is arranged on the side end of the eccentric wheel 26, a second pressure plate 29 is installed on the end of the movable rod 28, and the second pressure plate 29 is installed on the side end of the second airbag 20, and a second spring 30 is arranged on the outer side of the movable rod 28. Turn on the motor 23, and the fan blade 25 is driven to rotate by the rotating shaft 24 of the motor 23, so that the air inside the cabinet 1 circulates, so as to perform heat dissipation operation, and reduce the problem of reduced service life due to heat influence. When the rotating shaft 24 rotates, the eccentric wheel 26 sleeved on its surface rotates, and the eccentric wheel 26 contacts with the movable plate 27. The moving rod 28 at the moving side end moves the second pressure plate 29. At this time, the second spring 30 on the outer side of the moving rod 28 is compressed, and the second pressure plate 29 squeezes the second airbag 20 in the storage box 19, so that the gas pressure in the second airbag 20 changes, thereby causing the gas rate ejected from the nozzle 22 to change, which is convenient for cleaning the dust on the filter screen 17 and greatly improves the overall cleaning efficiency. When the eccentric wheel 26 leaves the surface of the moving plate 27, the second spring 30 rebounds, so that the moving plate 27 returns to its initial position, which is convenient for the moving plate 27 to move again, thereby improving the overall practicality. In addition, since the first airbag 13 is connected to the second airbag 20, it is convenient to transport the air inside the first airbag 13 to the second airbag 20 for operation when the first airbag 13 is pressurized, so that the overall cleaning efficiency is greatly improved.
