Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0032] Please refer to Figures 1 - 8 , the present utility model provides the following technical solutions.

[0033] Embodiment 1: In order to solve the problems existing in the prior art, therefore, in this embodiment, through the following technical solutions, a PLC control cabinet with a retractable tray is provided, which is provided with a PLC control cabinet body 1, a fixed rail 2 and a fixed tray 3. Both the left and right ends inside the PLC control cabinet body 1 are fixedly connected with fixed rails 2, and a fixed tray 3 is slidably connected to the middle of the fixed rail 2. At the same time, positioning blocks 18 are fixedly connected to the front and rear sides of the upper end of the fixed rail 2. Through the setting of the fixed tray 3, it is convenient to take and place maintenance tools when performing maintenance operations on the PLC control cabinet body 1.

[0034] Embodiment 2: In the existing PLC control cabinet, there is a lack of a limiting structure between the tray and the cabinet body. Therefore, during the use of the tray, when pulling the tray, it is easy to directly pull the tray out and cause it to fall off from the cabinet body, resulting in the tools stored falling. Therefore, by setting a fixing mechanism 4 and a heat dissipation groove 9, the fixing mechanism 4 includes a fixed rod 5 in a "T" shape, a first spring 6 sleeved on the outer surface of the fixed rod 5, a movable plate 7 fixedly connected to the movable end of the first spring 6, and a pull rod 8 fixedly connected to the upper end of the movable plate 7. A sliding structure is formed between the movable plate 7 and the fixed rod 5, and the fixed rod 5 is fixedly connected to the left and right sides of the rear end of the fixed tray 3. A front-back sliding structure is formed between the fixed rod 5 and the fixed rail 2. The movable plate 7 is snap-fitted with the positioning block 18, as Figure 1 , Figure 2 , Figure 3 , Figure 5and Figure 6 As shown, when the pull rod 8 is pulled upward, the pull rod 8 drives the movable plate 7 to move upward. At this time, the movable plate 7 slides between the fixed rod 5. The movable plate 7 squeezes the first spring 6, causing the first spring 6 to undergo elastic deformation. At this time, the movable plate 7 is separated from the positioning block 18 at the rear side of the upper end of the fixed rail 2, thereby releasing the limit between the fixed tray 3 and the fixed rail 2. Then, when the fixed tray 3 is pulled forward, the fixed tray 3 slides between the fixed rail 2. The fixed tray 3 drives the fixed rod 5 to slide between the fixed rail 2. After the fixed tray 3 is pulled out from the PLC control cabinet body 1, the pull rod 8 is directly released. At this time, the first spring 6 restores elastic deformation, driving the movable plate 7 to slide downward, so that the movable plate 7 engages with the positioning block 18 on the front side of the fixed rail 2, thereby facilitating the limitation between the fixed tray 3 and the fixed rail 2 and preventing the fixed tray 3 from slipping out of the PLC control cabinet body 1, resulting in the tools stored in the fixed tray 3 from falling.

[0035] Embodiment 3: The dust-proof effect of the existing PLC control cabinet body is poor, and external dust easily enters the cabinet body. Therefore, by setting a dust-proof net 10, a connecting plate 11, a convex column 12, an auxiliary block 13, a positioning plate 14, a second torsion spring 15, a movable pin 16 and an auxiliary rod 17, the dust-proof net 10 is inserted in the middle of the connecting plate 11, and the connecting plate 11 is respectively fixedly connected to the front and rear ends of the outer side of the PLC control cabinet body 1. Convex columns 12 are fixedly connected to the left and right sides of the upper end of the PLC control cabinet body 1. An auxiliary block 13 is fixedly connected to the upper end of the PLC control cabinet body 1. The middle part of the positioning plate 14 is hinged to the positioning plate 14. A second torsion spring 15 is arranged inside the positioning plate 14, and the movable end of the second torsion spring 15 is fixedly connected to the movable pin 16. The positioning plate 14 is sleeved outside the auxiliary block 13, and the positioning plate 14 is attached to the upper end of the convex column 12. An auxiliary rod 17 is fixedly connected to the side of the movable pin 16, and both the auxiliary rod 17 and the movable pin 16 form a sliding structure with the positioning plate 14. The movable pin 16 is inserted into the middle of the auxiliary block 13, as Figure 1 、such as Figure 4 、 Figure 7 and Figure 8As shown, the dust-proof net 10 is placed outside the heat dissipation slot 9. Through the setting of the dust-proof net 10, it can prevent dust from the outside from entering the PLC control cabinet body 1 through the heat dissipation slot 9 during the ventilation and heat dissipation process. When it is necessary to clean the dust-proof net 10, the auxiliary rod 17 can be directly pulled. The auxiliary rod 17 drives the movable pin 16 to slide in the positioning plate 14. At this time, the movable pin 16 squeezes the second torsion spring 15, causing the second torsion spring 15 to undergo elastic deformation. The movable pin 16 disengages from the convex post 12, thereby releasing the limit between the positioning plate 14 and the convex post 12. Then, the positioning plate 14 is flipped, and the positioning plate 14 rotates with the auxiliary block 13. The positioning plate 14 disengages from the convex post 12 and the dust-proof net 10, thereby releasing the limit on the dust-proof net 10. Then, the dust-proof net 10 is pulled upward, and the dust-proof net 10 is withdrawn from the connecting plate 11, thereby facilitating the disassembly and cleaning of the dust-proof net 10 and preventing the dust-proof net 10 from being blocked by dust.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
