[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0034] It should be noted that when a component is referred to as being "fixed on" or "disposed on" another component, it may be directly or indirectly located on the other component. When a component is referred to as being "connected to" another component, it may be directly or indirectly connected to the other component. The directions or positions indicated by the terms "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the directions or positions shown in the accompanying drawings and are only for the convenience of description and cannot be understood as limitations on the present technical solution. The terms "first" and "second" are only used for the convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0035] The following describes the PLC automation control cabinet of the embodiment of the present application in conjunction with the accompanying drawings. It can be understood that a variety of components and circuits are placed in the PLC automation control cabinet. Once the internal circuits are messy, the operator needs to comb the circuits many times during maintenance. In addition, the entangled circuits are prone to cause electric fires after aging. For this reason, the present embodiment provides a PLC automation control cabinet that is convenient for limiting circuits.

[0036] See also Figure 1 , Figure 1 A three-dimensional diagram of the PLC automation control cabinet of the present application is shown, which includes a protective cabinet 1 and a wiring harness 2. The protective cabinet 1 is used to place various components and lines, and the wiring harness 2 is used to limit the lines. The lines can be placed in the protective cabinet 1 in an orderly manner.

[0037] Specifically, see Figure 1-Figure 3 The protective cabinet 1 is provided with an inner cavity 11, and the components and connecting lines are placed in the inner cavity 11. The wiring harness part 2 is provided on the cavity wall of the inner cavity 11, and a wiring harness groove 21 and a slide groove 22 are provided on the wiring harness part 2. A slider 23 suitable for reciprocating sliding in the slide groove 22 is provided in the slide groove 22, and a shift lever 24 is rotatably connected to the slider 23. When the slider 23 reciprocates in the slide groove 22, the shift lever 24 blocks or avoids the notch of the wiring harness groove 21, and when the shift lever 24 rotates relative to the slider 23, it blocks or avoids the notch of the wiring harness groove 21.

[0038] When arranging the wires in the protective cabinet 1 , it is necessary to open the notch of the wire harness trough 21 , place the wires into the wire harness trough 21 , and then block the notch of the wire harness trough 21 , so that the wires can be limited in the wire harness trough 21 .

[0039] To this end, the present application provides two different limit adjustment methods: adjustment of the slider 23 and adjustment of the lever 24 .

[0040] When the slider 23 is used for adjustment, the slider 23 is moved to move in the slide groove 22, and the slider 23 drives the lever 24 to move synchronously. The lever 24 opens the notch of the cable trough 21 during the movement, and then the line is placed in the cable trough 21. The slider 23 is moved in the opposite direction, and the lever 24 moves synchronously and blocks the notch of the cable trough 21, thereby limiting the line in the cable trough 21.

[0041] When the lever 24 is used for adjustment, there is no need to move the slider 23. The lever 24 is rotated to avoid the notch of the cable trough 21, and then the line is placed in the cable trough 21. The lever 24 is then rotated in the opposite direction. The lever 24 blocks the notch of the cable trough 21 and limits the line in the cable trough 21.

[0042] Therefore, the present application can realize two different limit adjustment methods, namely, adjustment of the slider 23 and adjustment of the lever 24. The staff can choose to use the two limit adjustment methods to realize the binding and organization of the lines, avoid disorder of the lines, and make the operation convenient and efficient.

[0043] Furthermore, when the lines in the protective cabinet 1 are sorted, they are divided into two situations according to the number of lines: a large number of lines and a small number of lines. When the number of lines to be placed in the cable trough 21 is large, the line group consisting of multiple lines is thicker, and the notch of the cable trough 21 needs to be opened as much as possible to quickly place the line group in the cable trough 21. When the number of lines to be placed in the cable trough 21 is small, the line group consisting of multiple lines is thinner, and the notch of the cable trough 21 does not need to be completely open, and the line group can also be quickly placed in the cable trough 21.

[0044] The present application provides two different limit adjustment methods, which are respectively suitable for the cases of many lines and few lines.

[0045] Specifically, when a large number of lines need to be placed in the cable trough 21, the slider 23 is used to adjust the line. By moving the slider 23, the lever 24 is driven to move until the slot of the cable trough 21 is completely open, so that relatively thicker line groups can be placed in the cable trough 21. Then the slider 23 is returned to the initial position, and the lever 24 blocks the slot of the cable trough 21 to complete the arrangement of the line groups.

[0046] When the number of lines that need to be placed in the cable trough 21 is small, the lever 24 is used to adjust the line group, and the lever 24 is pushed from the outside of the cable trough 21 to rotate the lever 24 into the cable trough 21. After the lever 24 rotates a certain angle, a certain gap will be formed between the lever 24 and the notch of the cable trough 21. At this time, although the notch of the cable trough 21 is not completely open, the line group can directly enter the cable trough 21 through the gap. Then the lever 24 is adjusted back to the initial position to block the notch of the cable trough 21. The arrangement of the line group is completed, and there is no need to adjust the slider 23, and the staff can complete the arrangement of the line group with one hand.

[0047] It can be understood that the lever 24 can be flipped into the cable trough 21 or out of the cable trough 21, but many components are placed in the protective cabinet 1, which will cause the operable space of the inner cavity 11 to become smaller. In some cases, if the lever 24 is adjusted to rotate away from the cable trough 21, the lever 24 will be blocked by the components, that is, the lever 24 cannot be flipped outward. In this case, it is still feasible to flip the lever 24 inward. Therefore, the present application is also applicable to the situation where the operable space of the inner cavity 11 is narrow, and has a wider range of applications.

[0048] Furthermore, when there are many lines placed in the cable trough 21, the lever 24 may be squeezed by the lines and flipped outward from the cable trough 21, causing the lines to detach from the cable trough 21. To this end, in some embodiments, a block (not shown) extending to the lever 24 is provided on the slider 23, and when the lever 24 rotates in a direction away from the notch of the cable trough 21, the block stops the lever 24. In other words, through the provided block, the lever blocked in the notch of the cable trough 21 can only rotate into the cable trough 21, and cannot rotate in a direction away from the notch of the cable trough 21. In this way, it is possible to avoid the situation where the group of lines placed in the cable trough 21 squeezes the lever 24, causing the lever 24 to flip outward, and the group of lines detaches from the cable trough 21, thereby improving the stability of line arrangement.

[0049] Furthermore, regarding the structure of the cable trough 21, the cable trough 21 has a notch and two through openings. The cable trough 21 penetrates the cable harness portion 2 along the direction of the two through openings. The line is placed in and out of the cable trough 21 through the notch. Both ends of the line placed in the cable trough 21 extend out of the cable trough 21 through the two through openings.

[0050] In some embodiments, see Figure 1-Figure 3 To facilitate the adjustment of the slider 23, a first reset member 25 is provided in the slide groove 22, and the slider 23 is connected to the first reset member 25. When the slider 23 slides, the first reset member 25 drives the slider 23 to recover and remain in the first position.

[0051] It should be noted that when the slider 23 is in the first position and the lever 24 connected to the slider 23 is not rotated, the lever 24 blocks the notch of the cable trough 21. That is to say, when the first reset member 25 is in a free state, the first reset member 25 drives the slider 23 to remain in the first position, and the notch of the cable trough 21 is blocked by the lever 24. When an external force drives the slider 23 to move, the slider 23 will drive the lever 24 to move and avoid the notch of the cable trough 21. After the external force disappears, the first reset member 25 drives the slider 23 and the lever 24 to move to the first position and blocks the notch of the cable trough 21. Thereby, the slider 23 is automatically reset.

[0052] Further, see Figure 1-Figure 3To facilitate the adjustment of the lever 24, a second reset member 26 is connected between the lever 24 and the slider 23. When the lever 24 rotates, the second reset member 26 drives the lever 24 to return to and remain in the second position.

[0053] Similarly, when the lever 24 is in the second position and connected to the slider 23 in the first position, the lever 24 blocks the notch of the cable trough 21. That is to say, when the second reset member 26 is in a free state, the second reset member 26 drives the lever 24 to remain in the second position, and the notch of the cable trough 21 is blocked by the lever 24. When an external force drives the lever 24 to rotate, the lever 24 will avoid the notch of the cable trough 21. After the external force disappears, the second reset member 26 will drive the lever 24 to move to the second position and block the notch of the cable trough 21. Thereby, the lever 24 is automatically reset.

[0054] Therefore, when the slider 23 and the shift rod 24 are not subjected to external force, the shift rod 24 blocks the notch of the wiring harness trough 21; when the slider 23 is pushed by external force, the slider 23 moves and drives the shift rod 24 to move, and the shift rod 24 avoids the notch of the wiring harness trough 21. After the external force disappears, the first reset member 25 drives the slider 23 to return to the first position, and the shift rod 24 blocks the notch of the wiring harness trough 21; when the slider 23 is pushed by external force and the shift rod 24 is pushed by external force, the shift rod 24 rotates into the wiring harness trough 21, and a certain gap is avoided in the notch of the wiring harness trough 21 for the line to enter the wiring harness trough 21. When the external force disappears, the second reset member 26 drives the shift rod 24 to return to the second position, and the shift rod 24 blocks the notch of the wiring harness trough 21.

[0055] In some embodiments, see Figure 3 The first return member 25 and the second return member 26 are both return springs.

[0056] Further, to facilitate the movement of the slider 23, refer to Figure 2 A shift block 27 is provided on the slider 23 , and the shift block 27 extends out of the slide groove 22 and protrudes from the outer surface of the cable harness portion 2 .

[0057] Since the slider 23 is arranged in the slide groove 22, when the slider 23 needs to be moved, the shifting block 27 located outside the wiring harness portion 2 can be directly shifted, and the slider 23 can be driven to move by the shifting block 27, which makes the operation more convenient.

[0058] Further, regarding the structure of the slide groove 22, the notch of the slide groove 22 is connected to the outside of the cable harness 2, a portion of the shift block 27 is located in the slide groove 22 and connected to the slider 23, and another portion of the shift block 27 extends to the outside of the slide groove 22 through the notch of the slide groove 22. In some embodiments, a slide rail is provided in the slide groove 22, and the slider 23 is slidably connected to the slide rail to enable the slider 23 to slide in the slide groove 22.

[0059] In some embodiments, see Figure 3 The slide groove 22 includes a receiving groove 28 arranged therein, the first reset member 25 is arranged in the receiving groove 28, and the first reset member 25 and the slider 23 are connected by a connecting block 29.

[0060] The receiving groove 28 is provided to provide a receiving space for the first restoring member 25. After the first restoring member 25 is placed in the receiving groove 28, it no longer occupies the space in the slide groove 22, thereby simplifying the structure of the slide groove 22 and further achieving the effect of simplifying the structural size of the wiring harness part 2.

[0061] In some embodiments, the slot of the receiving slot 28 is connected to the slide slot 22, and the receiving slot and the slide slot 22 are arranged in a vertical position relationship. For example, see Figure 3 The receiving groove is located below the slide groove 22, and the slider 23 located above is connected to the first reset member 25 located below through the connecting block 29, so as to realize the transmission effect of the slider 23 and the first reset member 25. After such arrangement, compared with the receiving groove and the slide groove 22 being arranged on the same straight line, it saves more space and further simplifies the structural size of the wiring harness part 2.

[0062] In some embodiments, see Figure 2 The wiring harness portion 2 includes a plurality of wiring harness portions 2 connected to form an integrated structure, wherein a plurality represents no less than two.

[0063] When there are many components and lines in the protective cabinet 1, the lines need to be classified while being sorted. The integrated structure formed by multiple wiring harnesses 2 can be conveniently installed in the inner cavity 11 of the protective cabinet 1, and multiple wiring harnesses 2 can meet the needs of sorting multiple lines. After the lines are sorted, the same type of lines can be placed in one wiring harness 2. Multiple wiring harnesses 2 can provide sorting of various types of lines, and the lines in the protective cabinet 1 can be sorted on the wiring harness 2 in a more orderly manner.

[0064] In some embodiments, see Figure 1 and Figure 4 The protective cabinet 1 also includes a protective door 3, which is hinged on the protective cabinet 1 and used to close the inner cavity 11. The protective door 3 is provided with an installation opening 31 that passes through the inner cavity 11, and a radiator (not shown) is provided on the installation opening 31.

[0065] Since there are many components in the protection cabinet 1, it is particularly important to dissipate heat inside the protection cabinet 1. After the radiator is arranged on the installation opening 31, the radiator can exchange the heat in the inner cavity 11 to the outside of the protection cabinet 1, thereby dissipating heat in the inner cavity 11 of the protection cabinet 1. Different from the components arranged in the inner cavity 11, the radiator is arranged on the protection door 3, which is more convenient for disassembly and assembly, and is conducive to the maintenance of the radiator by the staff.

[0066] Further, to improve the stability of the radiator installation, refer to Figure 1 and Figure 4 A limiting groove 32 is provided on the protective door 3, and the notch of the limiting groove 32 faces the installation opening 31. A screw 33 that can rotate in the limiting groove 32 is axially connected to the limiting groove 32. Two screw sleeves 34 are threadedly sleeved on the screw 33. Each screw sleeve 34 is connected to a clamping plate 35 for clamping the radiator. The clamping plate 35 extends to the outside of the limiting groove 32 through the notch of the limiting groove 32. When the screw 33 rotates, the screw sleeve 34 drives the clamping plates 35 to move closer to or away from each other along the length direction of the screw 33.

[0067] After the screw 33 in the limiting groove 32 is rotated, the screw 33 axially connected in the limiting groove 32 rotates, the screw 33 and the screw sleeve 34 perform relative spiral motion, the spiral rotation of the screw sleeve 34 is converted into linear motion, the screw sleeve 34 moves linearly along the length direction of the screw 33, and the screw sleeve 34 drives the clamping plate 35 to move when moving.

[0068] Before the radiator is set on the mounting opening 31, the two screw sleeves 34 are moved away from each other by rotating the screw rod 33. At this time, the two clamping plates 35 are also moved away from each other. Then the radiator is installed on the mounting opening 31. At this time, the two clamping plates 35 are kept on both sides of the radiator. Then, the screw rod 33 is rotated in the opposite direction to make the two screw sleeves 34 approach each other. At this time, the two clamping plates 35 are also approached each other until the two clamping plates 35 are clamped to both sides of the radiator, thereby fixing the radiator and ensuring the structural stability of the radiator after installation.

[0069] Furthermore, the screw 33 is a bidirectional screw having a self-locking property, that is, when the load stops applying force, the friction between the lines on the bidirectional screw prevents the bidirectional screw from automatically loosening or moving, and the bidirectional screw remains in its current position.

[0070] In some embodiments, see Figure 1 and Figure 4 A placement plate 36 for abutting the radiator is provided on the protective door 3. The placement plate 36 and the limiting groove 32 are located on opposite sides of the installation opening 31. The placement plate 36 can support the radiator, offset the gravity of the radiator, and prevent the radiator from falling.

[0071] Further, see Figure 1 A roller 4 is provided at the bottom of the protective cabinet 1.

[0072] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
