Description

Technical Field

[0001] The utility model relates to a control box, in particular to a control box for an automatic control instrument, and belongs to the technical field of industrial automation. Background Art

[0002] In the prior art, for example, the utility model with application number 202221015469.9 discloses a control box for an industrial automation control instrument system. In order to solve the problem that when the internal circuits and electrical components need to be inspected, maintenance personnel need to lean into the box, which is inconvenient for maintenance. The mounting plate for installing the electrical components is sleeved in the cylinder through the through hole. When the electrical components and circuits on the mounting plate need to be inspected, the limit ring is first removed, and then the mounting plate is pulled toward the outside of the control box, so that the mounting plate can be pulled out of the control box by a certain distance, avoiding the maintenance personnel from leaning into the box during maintenance. At the same time, a net bag for placing items is set on the box door through a fixing rod, and some commonly used tools can be placed in the net bag for placing items, avoiding the maintenance personnel from carrying tools with them, making it convenient to take the tools at any time during maintenance.

[0003] Similar to the above application, there are still some shortcomings:

[0004] The design of the mounting plate being stretchable is convenient for maintenance work, but in order to ensure that the mounting plate can be extended and retracted, a longer wire needs to be reserved inside the control box so that the instrument can be extended and retracted with the mounting plate. However, it is inconvenient to hide and retract the wires during the extension and retraction control process, which easily causes the internal wiring of the control box to be messy and has low practicality.

[0005] Therefore, a control box for automatic control instrument is designed to optimize the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0023] like Figure 1-Figure 4 As shown, this embodiment provides a control box for an automation control instrument, including a mounting plate 1 and a cross bar 2 evenly mounted on the inner end surface of the mounting plate 1, the top and bottom ends of the mounting plate 1 are hingedly mounted with end plates 3, both sides of the mounting plate 1 are hingedly mounted with side panels 4, the inner end surfaces of the end plates 3 and the ends of the side panels 4 are plugged into each other, a box door 8 is hingedly mounted on the outer side of one group of side panels 4, a switch lock is provided between the box door 8 and the other group of side panels 4, and an unfolding mechanism 9 for opening the end plates 3 and the side panels 4 outwards is provided on the outer side of the inner end surface of the mounting plate 1.

[0024] The overall working principle: when assembling the control box, first spread out the entire device, then rotate the side panel 4 ninety degrees around the hinge point, and then rotate the end panel 3 ninety degrees around the hinge point. At the same time, the end of the side panel 4 will be inserted into the interior of the end panel 3 to stabilize the position of the end panel 3 and the side panel 4 to form a side frame of the control box. The door 8 is then fixed using the switch lock of the door 8. The control box is assembled and then installed for use. When the interior of the control box needs to be inspected, the side panel 4, end panel 3 and door 8 are unfolded to highlight the interior of the control box, making inspection more convenient.

[0025] In this embodiment, three groups of cross bars 2 are provided, and the cross bars 2 are parallel to each other, and mounting holes are provided on the cross bars 2 .

[0026] Partial working principle: When installing the electrical components, fit the electrical components to the outside of the crossbar 2 and fix the electrical components with bolts passing through the mounting holes.

[0027] In this embodiment, plug blocks 5 are fixed to the top and bottom ends of the side panels 4, slots 6 cooperating with the plug blocks 5 are provided on the inner end faces of the end panels 3, and locking mechanisms 7 for positioning the plug blocks 5 are provided inside the end panels 3.

[0028] Partial working principle: When assembling the control box, after the side panel 4 is flipped over, align the slot 6 on the end panel 3 with the plug 5, insert the plug 5 into the slot 6 to complete the connection between the side panel 4 and the end panel 3, and then use the locking mechanism 7 to reinforce the position of the plug 5 to ensure the plug-in stability of the side panel 4 and the end panel 3.

[0029] In this embodiment, the locking mechanism 7 includes a slide groove 10, an insertion rod 11, a first spring 12 and a drag block 13. The slide groove 10 is opened inside the end plate 3. The insertion rods 11 are slidably provided at both ends of the slide groove 10, and the insertion rods 11 are extended to the inside of the slot 6. The insertion blocks 5 are provided with insertion holes that cooperate with the insertion rods 11. A first spring 12 is provided between the ends of the two groups of insertion rods 11. A drag block 13 is fixed to the end of the insertion rod 11 away from the slot 6, and the drag block 13 extends to the outside of the end plate 3.

[0030] Local working principle: After the plug block 5 is inserted into the slot 6, the first spring 12 controls the two groups of plug rods 11 to move in opposite directions and are inserted into the socket inside the plug block 5 to locate the position of the plug block 5. When the positioning state of the plug block 5 needs to be released, the fingers hold the two groups of drag blocks 13 respectively to control the two plug rods 11 to move toward each other, and the ends of the plug rods 11 are pulled out from the inside of the socket to release the positioning state of the plug block 5.

[0031] In this embodiment, the bottom of the insertion rod 11 at one end inside the slot 6 is in an arc shape, and the top of the insertion rod 11 at one end inside the slot 6 is a horizontal plane.

[0032] Partial working principle: Due to the arc-shaped setting of the bottom end of the insertion rod 11, during the assembly process, the top end of the insertion block 5 can contact the arc-shaped surface of the insertion rod 11, automatically squeezing the insertion rod 11 into the inside of the slide groove 10, making assembly more convenient.

[0033] In this embodiment, the unfolding mechanism 9 includes a guide groove 14, a slider 15, a second spring 16 and a connecting rod 17. The guide groove 14 is evenly arranged at the four sides of the inner end surface of the mounting plate 1. The inside of the guide groove 14 is slidably provided with a slider 15. A second spring 16 is provided between one side of the slider 15 close to the middle of the mounting plate 1 and the inner end of the guide groove 14. A connecting rod 17 is hingedly installed on the outer side of the slider 15, and the end of the connecting rod 17 away from the slider 15 is hingedly installed on the inner end surfaces of the end plate 3 and the side plate 4 respectively.

[0034] Local working principle: After the control box is assembled, the second spring 16 is in a compressed state. After the limiting state of the end plate 4 and the side plate 3 is released, the second spring 16 is reset to apply a thrust to the slider 15, which is applied to the side plate 4 and the end plate 3 through the connecting rod 17, and the end plate 3 and the side plate 4 are expanded outward, making it easier to open them during maintenance.

[0035] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
