DETAILED DESCRIPTION

[0017] In order to make the above-mentioned purposes, features and advantages of the present application more apparent, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0018] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in other ways that are not consistent with the description, and those skilled in the art can make similar generalizations without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0019] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. In this specification, "in one embodiment" does not mean the same embodiment, nor does it mean an embodiment that is separate or selectively excluded from other embodiments.

[0020] Embodiment 1: Please refer to Figure 1 - Figure 4 , the first embodiment of the present application, The embodiment provides a DCS distributed control system assembled cabinet heat dissipation air duct, which comprises a duct shell 1, a mounting shell 2, a connecting shell 3 and a heat dissipation fan 4, the mounting shell 2 penetrates into the inside of the duct shell 1, the connecting shell 3 is fixedly installed at the front end of the mounting shell 2, the heat dissipation fan 4 is embedded in the inside of the mounting shell 2, and the heat dissipation fan 4 further comprises: a dismounting mechanism 5 and a filtering mechanism 6, the dismounting mechanism 5 is arranged at the top end of the mounting shell 2, and the filtering mechanism 6 is arranged in the inside of the connecting shell 3.

[0021] Specifically, the dismounting mechanism 5 comprises a sliding plate 501, the sliding plate 501 is slidably connected at the top end of the duct shell 1, and a sliding groove 502 is formed in the inside of the sliding plate 501.

[0022] Further, the duct shell 1 is a hollow structure, the inside of the duct shell 1 is used for gas circulation and interaction, so that the gas is introduced to improve the circulation, and the cabinet is cooled.

[0023] Specifically, the inside of the sliding groove 502 penetrates a connecting rod 503, and a rotating chuck 504 is fixedly installed at one end of the connecting rod 503 penetrating into the duct shell 1.

[0024] Further, the rotating chuck 504 is slidably and rotatably connected with the connecting rod 503 through the sliding groove 502, and two groups are arranged, and the top end and the bottom end of the duct shell 1 can be adjusted.

[0025] Specifically, a through groove 505 is formed in the inner wall of the mounting shell 2, and an extension plate 506 is fixedly installed at one end of the sliding plate 501 penetrating into the through groove 505.

[0026] Further, the connecting rod 503 is rotatably connected with the duct shell 1 through the rotating chuck 504, so that the sliding plate 501 can be rotatably or slidably connected, so that the sliding plate 501 is inserted into the through groove 505, and the mounting shell 2 is dismounted.

[0027] Specifically, a spring 507 is fixedly installed at the top end of the extension plate 506, a resisting plate 508 is fixedly installed at the top end of the spring 507, and a supporting rod 509 is fixedly installed in the inside of the spring 507 at the top end of the extension plate 506.

[0028] Further, when the sliding plate 501 drives the extension plate 506 to penetrate out of the through groove 505, the spring 507 is elastically pushed, the resisting plate 508 is pushed to form a clamping form with the through groove 505, and the stability after assembly is further improved.

[0029] In use, firstly, the mounting shell 2 drives the connecting shell 3 to pass through the air duct shell 1. With the cooperation of the connecting rod 503 and the rotating chuck 504, the sliding plate 501 rotates and slides through the sliding groove 502 and is inserted into the through groove 505 of the mounting shell 2 to provide initial positioning. At the same time, with the extension plate 506 fixed, the spring 507 elastically pushes the abutment plate 508 to engage with the through groove 505 to prevent loosening. The support rod 509 is fixed on the extension plate 506 and can be inserted into the abutment plate 508, thereby providing a certain support force for the spring 507 to prevent excessive bending. After fixing, the cooling fan 4 increases airflow for heat dissipation. When disassembling, pressing the abutment plate 508 to compress the spring 507 and the space of the through groove 505 allows for disassembly.

[0030] In summary, the mounting shell 2 can be easily and quickly disassembled and assembled by rotating and sliding the sliding plate 501. The spring 507 pushes the contact plate 508 to abut against one side of the through groove 505 to form a locking structure, which improves the stability after installation. When disassembling or assembling, the contact plate 508 can be pressed to allow it to pass through the through groove 505, so that the entire mounting shell 2 can drive the cooling fan 4 to be assembled quickly, avoiding the troublesome use of bolts and other methods.

[0031] Example 2: Please see Figure 1 , Figure 2 and Figure 5 This is the second embodiment of the present utility model.

[0032] Specifically, the filter mechanism 6 includes an insertion groove 601, which is located at the top of the connecting shell 3. An insertion plate 602 is inserted inside the insertion groove 601, and a pressure plate 603 is fixedly installed at the front end of the extension plate 506.

[0033] Furthermore, when the insertion plate 602 is inserted into the insertion slot 601, the pressure plate 603, driven by the extension plate 506, closes the insertion slot 601 to fix the insertion plate 602, making the insertion plate 602 easy to disassemble and maintain.

[0034] Specifically, limit blocks 604 are fixedly installed on both sides of the inner side of the connecting shell 3, and limit grooves 605 are opened on the outer wall of the insert plate 602 at the positions corresponding to the limit blocks 604.

[0035] Furthermore, the limiting groove 605 of the insert plate 602 slides into the connecting shell 3 along the limiting block 604 to avoid displacement and improve the overall stability of the insert plate 602 after installation.

[0036] Specifically, a first filter screen 606 is embedded at the front end of the insertion plate 602, and a second filter screen 607 is embedded at the rear end of the insertion plate 602.

[0037] Furthermore, the insertion plate 602 forms a double-layer filtration structure by setting a coarse-pore first filter screen 606 and a fine-pore second filter screen 607, which can prevent external dust and impurities from entering and affecting the internal components of the cabinet during heat dissipation.

[0038] In use, the insertion plate 602 drives the first filter screen 606 and the second filter screen 607 to enter the connecting shell 3 through the insertion groove 601. Under the action of the sliding plate 501 and the extension plate 506, the pressure plate 603 closes the insertion groove 601 to seal the insertion plate 602, thereby achieving the effect of quick assembly and disassembly. The stability of the insertion plate 602 can be improved by the engagement of the limiting block 604 and the limiting groove 605.

[0039] In summary, the insertion plate 602, the first filter screen 606, and the second filter screen 607 work together to achieve double-layer filtration to prevent external dust and other contaminants from entering. The limiting block 604 engages with the limiting groove 605, improving the stability of the insertion plate 602 after it is inserted into the connecting shell 3. Under the cover of the pressure plate 603, the insertion plate 602 can be easily disassembled and assembled, allowing for the replacement and cleaning of the first filter screen 606 and the second filter screen 607.
