Description

Technical Field

[0001] This application relates to the field of protective enclosures, and more specifically, to an explosion-proof heat dissipation protective enclosure for PLC equipment. Background Technology

[0002] A PLC distribution box is a programmable enclosure, which refers to a complete control cabinet that can control motors and switches. PLC distribution boxes have protection functions such as overload, short circuit, and phase loss protection. Specifically, the control system is the brain of mechanical equipment. A series of purposeful, sequential, and rhythmic actions of the machine are all accomplished by the system.

[0003] Currently, PLC components are usually installed directly inside the chassis, with each component in direct contact. When one component malfunctions and explodes, it can severely affect other components. Furthermore, the dustproof mesh of the chassis is usually fixed to the side wall of the chassis. During long-term use and heat dissipation, dust can easily clog the mesh holes, making it difficult to remove and clean. Summary of the Invention

[0004] To overcome the shortcomings of the existing system, this application provides an explosion-proof heat dissipation protection enclosure for PLC equipment. This enclosure can solve the problem that when various components are in direct contact, a failure or explosion of one component can seriously affect other components. In addition, the dustproof mesh of the enclosure is usually fixed to the side wall of the enclosure. During long-term use and heat dissipation, dust can easily clog the mesh and make it difficult to remove and clean.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] An explosion-proof heat dissipation protective enclosure for a PLC device includes explosion-proof components and heat dissipation components.

[0007] The explosion-proof component includes a housing, a door, a mounting plate, a pad, and a connecting plate. The door is rotatably disposed on one side of the housing. The mounting plate is fixedly connected to the housing and has a partition groove. The pad is disposed on the other side of the housing. The connecting plate is slidably disposed on the side of the pad, and one end of the connecting plate is engaged with the pad.

[0008] The heat dissipation assembly includes a dustproof mesh, a retaining rod, and an elastic element. The side of the housing has a heat dissipation vent and a connecting groove. The dustproof mesh is disposed in the heat dissipation vent, the elastic element is disposed in the connecting groove, and the retaining rod is fixedly connected to the elastic element and is engaged with the dustproof mesh.

[0009] In one specific implementation, a wiring groove is provided at the bottom of the mounting plate, and the wiring groove is connected to the partition groove.

[0010] In the above implementation process, wiring channels that are connected to the partition channels are used to place the wiring for connecting components.

[0011] In one specific implementation, a fixing rod is provided on the side of the pad, and the connecting plate is slidably sleeved on the fixing rod.

[0012] In the above implementation process, a fixed rod is set for slidingly connecting the connecting plate, so that the position of the connecting plate can be adjusted by sliding.

[0013] In one specific implementation, the pad has a positioning opening, and a positioning block is provided on one side of the connecting plate. The positioning block and the positioning opening are adapted to be inserted into each other.

[0014] In the above implementation process, by opening multiple positioning ports, adjusting the position of the connecting plate by sliding, and then rotating the connecting plate to drive the positioning block to be inserted into the positioning port to achieve positioning.

[0015] In one specific implementation, the connecting plate is L-shaped and has through holes.

[0016] In one specific implementation, the elastic element includes a spring and a push plate, the spring is disposed in the communicating groove, the push plate slides through the communicating groove, and the locking rod is fixedly connected to the push plate.

[0017] In the above implementation process, by setting a spring and a push plate, the spring's elastic recovery action is used to push the push plate, which in turn drives the locking rod to engage and position the dustproof net.

[0018] In one specific implementation, the dustproof net has a slot at its bottom, and the locking rod is slidably inserted into the slot.

[0019] In the above implementation process, a card slot is opened, and when the card rod is inserted into the card slot, a locking action is achieved.

[0020] In one specific implementation, a wire-passing hole is provided at the bottom of the box.

[0021] In the above implementation process, multiple wire holes are opened so that the wires can pass through the wire holes into the box.

[0022] The advantages of this embodiment are: by setting up a box, box door, mounting plate, pad, and connecting plate, and opening a partition groove, each component is installed in the partition groove, which effectively prevents the explosion of one component from damaging other components. At the same time, the pad raises the box and the mounting surface, preventing the back of the box from being completely pressed together, which is conducive to heat dissipation. By setting up a dustproof net, clamps, and elastic elements, the dustproof net can be easily disassembled and installed, improving the efficiency of disassembling and cleaning the dustproof net.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with embodiments.

[0029] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0030] In the embodiments, unless otherwise specified, all methods used are conventional methods in the art.

[0031] Please see Figures 1-4 This application provides an explosion-proof heat dissipation protection enclosure for a PLC device, including an explosion-proof component 100 and a heat dissipation component 200.

[0032] Please see Figure 1 , 2 3. The explosion-proof component 100 includes a housing 110, a door 120, a mounting plate 130, a pad 140, and a connecting plate 150. The door 120 is rotatably disposed on one side of the housing 110. The mounting plate 130 is fixedly connected to the inside of the housing 110 and has a partition groove 131. The pad 140 is disposed on the other side of the housing 110. The connecting plate 150 is slidably disposed on the side of the pad 140, and one end of the connecting plate 150 is engaged with the pad 140.

[0033] The mounting plate 130 has a wiring groove 132 at the bottom, which is connected to the partition groove 131. The wiring groove 132, which is connected to the partition groove 131, is used to place the wiring of the connecting components.

[0034] Specifically, a fixing rod 141 is provided on the side of the pad 140, and the connecting plate 150 is slidably sleeved on the fixing rod 141. By setting the fixing rod 141, the connecting plate 150 is slidably sleeved on, so that the position of the connecting plate 150 can be adjusted.

[0035] In this embodiment, the pad 140 has a positioning port 142, and the connecting plate 150 has a positioning block 151 on one side. The positioning block 151 and the positioning port 142 are adapted to be inserted into each other. By opening multiple positioning ports 142, the position of the connecting plate 150 is adjusted by sliding, and the connecting plate 150 is rotated to drive the positioning block 151 to be inserted into the positioning port 142 to achieve positioning.

[0036] In one specific implementation, the connecting plate 150 is L-shaped and has through holes.

[0037] In one specific implementation, the bottom of the enclosure 110 is provided with a wire hole 113. By providing multiple wire holes 113, wires can be passed through the wire holes 113 into the enclosure 110.

[0038] Please see Figure 1 , 2 4. The heat dissipation component 200 includes a dustproof net 210, a locking rod 220 and an elastic element 240. The side of the housing 110 is provided with a heat dissipation vent 111 and a connecting groove 112. The dustproof net 210 is disposed in the heat dissipation vent 111, the elastic element 240 is disposed in the connecting groove 112, and the locking rod 220 is fixedly connected in the elastic element 240 and is locked in the dustproof net 210.

[0039] The elastic element 240 includes a spring 241 and a push plate 242. The spring 241 is disposed in the connecting groove 112, and the push plate 242 slides through the connecting groove 112. The locking rod 220 is fixedly connected to the push plate 242. By setting the spring 241 and the push plate 242, the elastic recovery of the spring 241 pushes the push plate 242, so that the push plate 242 drives the locking rod 220 to lock and position the dustproof net 210.

[0040] Specifically, the dustproof net 210 has a slot 211 at the bottom, and the locking rod 220 is slidably inserted into the slot 211. By opening the slot 211, the locking rod 220 is inserted into the slot 211 to achieve locking.

[0041] The working principle of the explosion-proof heat dissipation and protection enclosure for this PLC equipment is as follows: During use, components are individually installed in the partition slot 131, and the connecting wires are placed in the corresponding wiring slots 132. This effectively prevents a single component failure from exploding and damaging other components. For different installation points, the connecting plate 150 can be rotated to rotate the positioning block 151 out of the positioning port 142. Then, the connecting plate 150 can be slid along the axis of the fixing rod 141 to adjust its position, aligning the through hole of the connecting plate 150 with the pre-drilled hole for the installation position. Then, the connecting plate 150 can be rotated in the opposite direction to insert the positioning block 151 into the positioning port 142 for positioning. Finally, screws are used to secure the block. The bolt installation method greatly improves installation adaptability and practicality. After a period of use, pressing the push plate 242 compresses the spring 241, and the push plate 242 moves the locking rod 220 out of the slot 211, allowing the dust filter 210 to be removed and the attached dust to be cleaned. After cleaning, the spring 241's elastic recovery action pushes the push plate 242 back. After releasing the push plate 242, the push plate 242 drives the locking rod 220 to insert into the slot 211, locking and positioning the dust filter 210. This improves the efficiency of disassembling and cleaning the dust filter 210. At the same time, the pad 140 raises the box 110 and the installation position plane, preventing the back of the box 110 from being completely flat, which is beneficial for heat dissipation.

[0042] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
