DETAILED DESCRIPTION

[0021] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0022] Example 1

[0023] PLC control cabinet, such as Figure 1-3 As shown, it includes: a cabinet body 1, a cabinet door 2, a placement plate 3, a card plate 4, a pull block 5, a support plate 6, a stopper 7 and a torsion spring 8. The cabinet door 2 is rotatably installed on the front side of the cabinet body 1, and the placement plate 3 is rotatably installed on the inner side of the cabinet door 2. The support plate 6 is installed on the inner side of the cabinet door 2 through bolts. The support plate 6 is located below the placement plate 3. When the placement plate 3 rotates from a vertical state to a horizontal state, it contacts the support plate 6. The support plate 6 supports the placement plate 3. The top of the placement plate 3 is connected with the card plate 4 and the pull block 5 (as shown in FIG. Figure 2 As shown), a stopper 7 is rotatably connected to the inner side of the cabinet door 2, and the stopper 7 is located above the placement plate 3. When the placement plate 3 is in a vertical state, the stopper 7 can clamp the card plate 4, thereby fixing the position of the placement plate 3. A torsion spring 8 is connected between the stopper 7 and the cabinet door 2. Under the action of the torsion spring 8, the stopper 7 can stably resist the card plate 4.

[0024] like Figure 1 , 2 As shown in 4 , it also includes: a groove sealing strip 9, a raised sealing strip 10 and a stop strip 11. The side edge of the cabinet door 2 on one side is connected to the groove sealing strip 9, and the side edge of the cabinet door 2 on the other side is connected to the raised sealing strip 10 that cooperates with the groove sealing strip 9, and the stop strip 11 is connected to the raised sealing strip 10.

[0025] like Figure 1 As shown, it also includes: a handle 12 and an anti-skid pad 15. The handles 12 are installed on the outer sides of the cabinet doors 2 on both sides. The anti-skid pad 15 is arranged on the handle 12. The cabinet doors 2 can be opened conveniently by the handle 12. The anti-skid pad 15 has an anti-skid effect.

[0026] like Figure 1 and 3 As shown, it also includes: a placement box 13, and six placement boxes 13 are evenly spaced and slidably embedded on the placement plate 3.

[0027] like Figure 1 As shown, it also includes: adjustable supporting feet 14. Adjustable supporting feet 14 are installed at the four corners of the bottom of the cabinet 1. When the ground is uneven, the cabinet 1 can be adjusted by adjusting the supporting feet 14 so that the cabinet 1 can be placed stably.

[0028] When the staff needs to repair the internal circuits or equipment of the PLC control cabinet, they open the cabinet door 2 through the handle 12 and then rotate the stopper 7. At this time, the torsion spring 8 is deformed, the stopper 7 rotates to release the card plate 4, and the pull block 5 is pulled downward to rotate, thereby driving the placement plate 3 to rotate. When the placement plate 3 rotates to contact the support plate 6, the support plate 6 can support the position of the placement plate 3 so that the placement plate 3 remains in a horizontal state. The staff can now place the tools and accessories used in the maintenance process in the placement box 13. In this way, the staff can easily take or place the tools during the maintenance process. If the tools or accessories are small, the placement box 13 can be taken out of the placement plate 3, and then tilted. The tools and accessories are taken out in an upside-down manner. After the maintenance is completed, the tools and accessories are taken out from the placement box 13, and then the placement plate 3 is rotated upwards. The stopper 7 is used to resist the card plate 4, so that the placement plate 3 can be kept in a vertical state. Under the action of the torsion spring 8, it is ensured that the stopper 7 can stably resist the card plate 4 to prevent the placement plate 3 from rotating abnormally. Then the cabinet door 2 can be closed, and the raised sealing strip 10 is inserted into the groove sealing strip 9 to ensure the sealing inside the cabinet body 1, and the stopper 11 can further block the gap between the raised sealing strip 10 and the groove sealing strip 9, so as to prevent dust from entering the cabinet body 1 from the door gap during work, thereby affecting the service life of the internal circuits or equipment of the PLC control cabinet.

[0029] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
