[0037] The following is in conjunction with the appendix Figures 1-8 The present invention will be described in further detail below.

[0038] Example 1: A control cabinet for a bending machine, referring to... Figure 1 The machine includes the body 7 of the bending machine, with metal uprights on both sides of the body 7, and a control cabinet installed on the uprights; the control cabinet is a stainless steel cabinet 1, with electrical components installed inside; the cabinet 1 includes a cabinet door, and the cabinet 1 has an overall rectangular structure. Figure 5 In the middle, after cabinet 1 is opened, there are through holes on the back panel of cabinet 1 for screws to be inserted and fixed. Figure 1 In the middle, after the cabinet door of cabinet 1 is opened, the back panel of cabinet 1 is suspended and fixed to the upright plate of the body 7 by screws.

[0039] Reference Figures 2-3 A support rod 2 is rotatably connected to the bottom plate of cabinet 1;

[0040] Reference Figure 3 and Figure 4 The support rod 2 is a telescopic rod, which includes a main pipe 21 and a support rod 22. The support rod 22 slides inside the main pipe 21 and telescopically slides inside the main pipe 21.

[0041] The outer wall of the main pipe 21 is threaded with a locking fastener 24, which is a No. 2 bolt.

[0042] The support rod 22 is provided with a locking hole 23 for inserting a No. 2 bolt. There are two locking holes 23, which are arranged one above the other.

[0043] When the support rod 22 slides out of the main pipe 21 for support, such as Figure 4 The second bolt is inserted into the upper locking hole 23 to secure the two.

[0044] When the support rod 22 slides laterally into the main pipe 21 for storage, as Figure 3 The second bolt is inserted into the lower locking hole 23 to secure the two.

[0045] Reference Figure 2 and Figure 3 In order to enable the support rod 2 to rotate as a whole, the support rod 2 and the cabinet 1 are connected by a hinge 5, which is fixed to the end of the support rod 2 and the bottom of the cabinet 1.

[0046] When the support rod 2 is rotated to the lateral position, the support rod 2 is in a retracted state, and the main tube 21 is a square tube, the support rod 22 is a square rod, and the outer wall of the main tube 21 is in contact with the bottom plate of the cabinet 1.

[0047] When the support rod 2 is rotated to the vertical position, the support rod 2 is in the extended state, and the support rod 22 extends downward to touch the ground.

[0048] In order to ensure that the cabinet 1 has a good fastening ability to support the support rod 2 when it is stored and supported, the support rod 2 is locked by the No. 1 bolt 32 connected by the locking plate 31 at the bottom of the cabinet 1.

[0049] The locking plate 31 is a concave metal plate; the locking plate 31 is welded to the bottom plate of the cabinet 1, and the concave opening of the locking plate 31 faces the support rod 2.

[0050] The locking plate 31 is threadedly connected to a bolt 32, which points towards the support rod 2.

[0051] The top of the support rod 2, that is, the top of the main tube 21, has an upper hole 41 through which the connecting piece of the hinge 5 passes.

[0052] like Figure 2 When the support rod 2 is rotated to the horizontal storage position, the No. 1 bolt 32 is inserted into the upper hole 41 to keep the support rod 2 horizontally locked at the bottom of the cabinet 1. Due to the blocking effect of the No. 1 bolt 32, that is, the side of the No. 1 bolt 32 and the hole wall of the upper hole 41 block and limit the movement, the support rod 2 cannot rotate downward, thus achieving the purpose of storage and locking.

[0053] Then as Figure 3 Loosen bolt 32, and support rod 2 can rotate freely vertically.

[0054] The side of the support rod 2, that is, the top of the main pipe 21, is provided with a side hole 42. When the support rod 2 is rotated to the vertical support position, the No. 1 bolt 32 is inserted into the side hole 42 to keep the support rod 2 vertical and locked. At this time, the side of the No. 1 bolt 32 and the hole wall of the side hole 42 act as a barrier and limit, restricting the vertical rotation of the support rod 2. Therefore, the support rod 2 can be stably kept in the vertical position, and at this time, the top of the main pipe 21 and the bottom plate of the cabinet 1 achieve abutment support.

[0055] Further optimization is that, since the locking plate 31 is a concave plate, elastic blocks 6 are provided on the two opposite sides of the concave surface of the locking plate 31. The elastic blocks 6 are hot-melt rubber plates. When the support rod 2 is erected, the side of the support rod 2 is embedded into the concave surface of the locking plate 31, and the two sides of the support rod 2 compress the elastic blocks 6.

[0056] The working principle is that the No. 1 bolt 32 can be used to insert and lock the support for both horizontal storage and vertical standing.

[0057] When cabinet 1 is running normally in the bending machine, support rod 2 is horizontally stored at the bottom of cabinet 1.

[0058] When the control cabinet needs to be dismantled in the production workshop, the support rod 2 can be set vertically, with the bottom of the extended support rod 2 touching the ground. The support rod 2 supports the cabinet 1. After the workers remove the cabinet 1 from the bending machine, the cabinet 1 can be slowly laid down due to the supporting effect of the support rod 2. Its advantage is that no other workers need to be arranged to lift the cabinet 1 by hand during the dismantling process.

[0059] Example 2, a control cabinet for a bending machine, differs from Example 1 in that, see below. Figures 6-7 There are two support rods 2. The rotation points of the two support rods 2 are located at both ends of the bottom of the cabinet 1, that is, the two hinges 5 are located at both ends of the bottom of the cabinet 1. When the two support rods 2 are vertical, their span at the bottom of the cabinet 1 is large, so that the two support rods 2 can support the cabinet 1 more stably.

[0060] Example 3, a control cabinet for a bending machine, differs from Example 1 in that, see below. Figure 8 There are three support rods 2. The rotation point of the middle support rod 2 and the rotation points of the two outer support rods 2 are located at the two ends of the bottom of the cabinet 1, respectively. This design ensures that the three hinges 5 are not on the same straight line, meaning that the three support rods 2 are not on the same straight line when vertical.

[0061] This design allows the three support rods 2 to provide more stable vertical support for the cabinet 1.

[0062] Example 4, a control cabinet for a bending machine, differs from Example 1, Example 2, or Example 3 in that the outer wall of the support rod 2 is provided with rollers 81; the lower surface of the main pipe 21 is welded with a bushing 82, a rotating shaft is inserted into the bushing 82, and rollers 81 are installed at both ends of the rotating shaft, so that the rollers 81 are located on both sides of the main pipe 21.

[0063] Two bushings 82 are installed on one main tube 21, and there are a total of four rollers 81.

[0064] When the support rod 2 is set horizontally, the lower surface of the roller 81 is the lowest surface of the cabinet 1. After the cabinet 1 is disassembled, place the cabinet 1 on the ground, and then store the vertical support rod 2 in the horizontal position. Then straighten the cabinet 1 with the bottom facing the ground. At this time, the lower surface of the roller 81 is lower than the lower surface of the support rod 2, and the roller 81 is in contact with the ground. This design allows the user to directly push the cabinet 1, so that the cabinet 1 can move smoothly on the ground, making it easy to move the cabinet 1.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
