Description
Technical Field
[0001] The invention relates to the technical field of distribution boxes, in particular to a distribution cabinet with a grounding locking mechanism. Background Art
[0002] A power distribution cabinet with a grounding locking mechanism is a special power distribution equipment. It is specially designed with a grounding locking mechanism to ensure that the equipment can be safely grounded when the power distribution cabinet is repaired or inspected, thereby preventing electric shock and other potential safety risks. The grounding locking mechanism of this power distribution cabinet usually includes one or more locking devices, which can automatically start the grounding process when the power distribution cabinet door is opened. After the grounding process is completed, the locking device will lock the power distribution cabinet door to prevent the power distribution cabinet from being closed without releasing the ground. Only after the grounding is completely released, the locking device will be unlocked to allow the power distribution cabinet door to be closed. The main purpose of this design is to improve the safety of the staff and the stability of the power distribution system; by ensuring that the power distribution cabinet is always grounded during maintenance or inspection, the grounding locking mechanism can effectively prevent electric shock injuries caused by accidental contact with live parts. At the same time, it also helps to prevent equipment damage or system failure caused by ungrounded.
[0003] The grounding locking mechanism is mainly composed of a locking device, a grounding wire, a sensor, an actuator and a control system. The locking device is the core of the grounding locking mechanism. It locks the distribution cabinet door mechanically or electronically to prevent the distribution cabinet from being closed without grounding. The mechanical component of the grounding locking mechanism is more commonly a connecting mechanism, which can effectively control the grounding of the equipment. In actual application, the connecting rod mechanism often uses a screw as a connecting piece, mainly because the screw connection can provide a reliable fixing effect, ensuring the stability and accuracy of the connecting rod structure, and the use of a screw connection can facilitate the assembly and disassembly of the connecting rod structure. At the same time, by adjusting the tightness of the screw, the degree of connection of the connecting rod structure can be fine-tuned; thus, the screw plays a transmission role in the connecting rod mechanism. However, in the actual grounding process, the design of the grounding locking mechanism usually includes multiple movement stages, such as initial contact, gradual locking and final locking, and each stage has different speed requirements. For example, the initial contact stage may require a slower speed to ensure smooth contact, while the final locking stage may require a faster speed to improve work efficiency. During each grounding locking action, the screw is susceptible to certain vibrations and impact forces during the final locking stage, which makes the screw prone to bending and deformation, and then the connection strength of the screw will be reduced. During long-term use, the screw is prone to breakage, which will lead to grounding failure and increase the risk of electric shock. For this reason, we propose a distribution cabinet with a grounding locking mechanism. Summary of the invention

DETAILED DESCRIPTION
[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0034] See also Figure 1-14 The present invention provides a technical solution: a power distribution cabinet with a grounding locking mechanism. The present invention makes corresponding improvements to the technical problems in the background technology, including a cabinet 1, a grounding mechanism 2 fixedly installed inside the cabinet 1, a power mechanism 3 fixedly installed inside the cabinet 1, and a connecting hinge 4 fixedly installed on the power mechanism 3 and the grounding mechanism 2, and each connecting hinge 4 is connected to an articulated seat 5 through a pin 8, and the two articulated seats 5 are fixedly connected by bolts 6, wherein the angle difference between the articulated seats 5 is 90°, combined with the attached Figure 1-2As shown, the power mechanism 3 drives the connecting hinge rod 4 fixedly connected thereto to rotate, and under the action of the pin shaft 8, the articulated seat body 5 and the bolt 6, the grounding mechanism 2 is rotated, thereby achieving the purpose of regulating and locking the grounding mechanism 2; combined with the technical problems in the background technology, it can be known that the bolt 6 is prone to bending and deformation during long-term use. If it is not handled in time, the bolt 6 is prone to breakage during the subsequent locking work. In view of this, the present invention is designed as follows: each articulated seat body 5 is symmetrically fixedly installed with a fixed plate frame 51, and each fixed plate frame 51 is fixedly installed on one side with two support rod frames 52, one of which is close to the middle area of the bolt 6, and the other is close to the end of the bolt 6. Figure 3-7 , and a limit frame 53 is fixedly installed at the end of each support rod frame 52, wherein an arc-shaped rubber 54 is installed inside the limit frame 53, and the arc-shaped rubber 54 contacts the outer wall of the bolt 6; combined with the attached Figure 5 As shown, the arc rubber 54 is in close contact with the bolt 6, and because the angle difference between the hinged seat body 5 is 90°, when the bolt 6 is bent and deformed, it will act on the arc rubber 54. A connecting piece 7 is also provided on the arc rubber 54, and three sensing elements 521 are provided inside the support rod frame 52. The sensing elements 521 are located on the movement trajectory of the connecting piece 7, so that the bolt 6 is deformed to apply a force to the arc rubber 54, and the arc rubber 54 applies a force to the sensing elements 521 through the connecting piece 7; wherein an extension rod frame 55 is fixedly connected between the support rod frames 52, and the interiors of the support rod frames 52 and the extension rod frames 55 are in a connected state, and combined with the attached Figure 7 As shown, there are two sensing elements 521 inside the support rod frame 52 near the middle area of the bolt 6, and there is one sensing element 521 inside the support rod frame 52 near the end of the bolt 6. The degree of bending deformation of the bolt 6 can be effectively known according to the number of sensing elements 521 that are touched;
[0035] As a further limitation of the present invention, the connecting member 7 includes an action shaft 71 fixedly mounted on the arc rubber 54, and the end of the action shaft 71 sequentially penetrates the limit frame 53 and the inner wall of the support rod frame 52 and extends to the inside of the support rod frame 52, wherein a buffer spring 74 is also connected between the arc rubber 54 and the inner wall of the limit frame 53, and a connecting bracket 72 is fixedly mounted on one end of the action shaft 71, and a telescopic rod frame 73 is also fixedly mounted on the connecting bracket 72 near the middle area of the bolt 6, the first sensing element 521 is located on the movement trajectory of the telescopic rod frame 73, and a magnetic component 721 is also fixedly mounted on the connecting bracket 72 near the end of the bolt 6, as well as a The force-applying shaft 722, the second sensing element 521 is located on the movement trajectory of the force-applying shaft 722, and a force-applying rod frame 723 slidably connected to the inner wall thereof is also installed on the connecting bracket 72 close to the middle area of the bolt 6, and one end of the force-applying rod frame 723 is a magnetic surface. When the magnetic component 721 is located directly below the force-applying rod frame 723, a repulsive force is generated on the end of the force-applying rod frame 723. It should be noted that in the initial state, the magnetic component 721 is not located directly below the force-applying rod frame 723, and the third sensing element 521 is fixedly installed on the top of the support rod frame 52, and the support rod frame 52 is close to the middle area of the bolt 6, and the third sensing element 521 is located on the movement trajectory of the force-applying rod frame 723;
[0036] Further explanation, it is known from common sense that since there is no external supporting force in the middle area of the bolt 6, the middle area of the bolt 6 first appears bending deformation relative to the two ends. Then, when the middle area of the bolt 6 appears bending deformation, the first sensing element 521 inside the support rod frame 52 (close to the middle area of the bolt 6) will first be subjected to the force of the telescopic rod frame 73. At this time, it means that the bolt 6 has been bent and deformed, but it is in a controllable state. The staff can replace the bolt 6 during the next maintenance. When the degree of bending deformation of the bolt 6 increases, the second sensing element 521 inside the support rod frame 52 (close to the end of the bolt 6) Component 521 will be touched by the force-applying shaft 722. At this time, the power distribution cabinet (i.e., the cabinet 1 of the present invention) can continue to work, but the staff needs to replace the bolt 6 as soon as possible. When the bending degree of the bolt 6 continues to increase, the arc-shaped rubber 54 near the end of the bolt 6 will drive the connecting bracket 72 to continue to move through the action shaft 71, and then the magnetic component 721 on the connecting bracket 72 will move to the bottom of the force-applying rod frame 723. The magnetic component 721 generates a repulsive force on the force-applying shaft 722, so that the third induction element 521 is triggered. At this time, it is necessary to stop working to avoid the bolt 6 from breaking and causing grounding failure.
[0037] Step 1: During the ground locking operation, if the bolt 6 is bent, its bent area first acts on the arc rubber 54 near the middle area, that is, the arc rubber 54 is acted upon by the force to drive the action shaft 71 to move, and the action shaft 71 drives the connecting bracket 72 to move, and during the movement, the telescopic rod frame 73 on the connecting bracket 72 acts on the first sensing element 521, which indicates that the bending deformation of the bolt 6 is in a controllable state. If the bending deformation of the bolt 6 deepens, that is, the bending deformation area of the bolt 6 increases, the arc rubber 54 near the end of the bolt 6 will be acted upon by the force of the bolt 6 and move in a directional manner. During the movement, the arc rubber 54 drives the connecting bracket 72 and the force-applying shaft on one side thereof through the action shaft 71. 722 moves synchronously, and the force-applying shaft 722 acts on the second sensing element 521, which means that the bending degree of the bolt 6 increases at this time, but it can still continue to work. It is just that the staff needs to replace the bolt 6 as soon as possible to avoid the bolt 6 from breaking due to long-term use; when the bending degree of the bolt 6 continues to increase, the arc-shaped rubber 54 close to the end of the bolt 6 will drive the connecting bracket 72 to continue to move through the action shaft 71, and then the magnetic component 721 on the connecting bracket 72 will move to the bottom of the force-applying rod frame 723, and the magnetic component 721 will produce a repulsive force on the force-applying shaft 722, so that the third sensing element 521 is triggered. At this time, the bolt 6 needs to be replaced immediately to avoid the bolt 6 from breaking and causing grounding failure;
[0038] Furthermore, in actual application, the pin shaft 8 and the connecting hinge rod 4 often wear due to friction problems. When the pin shaft 8 wears, the overall movement of the connecting rod mechanism will be unstable, and the bolt 6 will be subjected to uneven force or impact load. During long-term operation, the bolt 6 is prone to bending and deformation. In view of this, the present invention is designed accordingly: first, a slot 81 is provided on the pin shaft 8 of the present invention, and a plurality of diverter slots 82 are also provided on the slot 81, wherein a limiting sleeve 9 is fixedly installed on the articulated seat body 5, wherein an injection mechanism 91 for storing lubricating oil is fixedly installed inside the limiting sleeve 9, and the injection mechanism 9 The discharge pipe of the injection mechanism 91 is located directly above the slot 81, so that the lubricating oil in the injection mechanism 91 enters and drips into the slot 81 through the discharge pipe of the injection mechanism 91, wherein the slot 81 in the present invention is arranged at an angle to facilitate the circulation of the lubricating oil, and the lubricating oil entering the slot 81 will lubricate the pin 8 and the connecting hinge rod 4 under the action of the diverter groove 82, the injection mechanism 91 is also equipped with a piston rod frame 92, and a plurality of force plate frames 93 are symmetrically fixedly installed on the piston rod frame 92, and a sliding plate frame 94 slidably connected to the inner wall of the limiting sleeve 9 is also installed inside, and a plurality of fixed frames 95 are symmetrically arranged on one side of the sliding plate frame 94, and the fixed frames 95 are arranged between They are connected to each other and fixedly connected to one side of the sliding plate frame 94. Each fixed frame 95 is internally installed with an action plate frame 96 slidably connected to its inner wall. A telescopic shaft 961 is fixedly installed on one side of each action plate frame 96. The action plate frame 96 corresponds to the force plate frame 93 one by one and is in contact with the force plate frame 93. A magnetic shaft 941 is also fixedly installed on one side of the sliding plate frame 94. Two force-applying magnetic plates 21 are also fixedly installed on the grounding mechanism 2. The force-applying magnetic plates 21 correspond to the magnetic shaft 941 one by one and are located on the movement trajectory of the magnetic shaft 941. When the magnetic shaft 941 moves to the corresponding position of the force-applying magnetic plate 21, the force-applying magnetic plate 21 contacts the magnetic shaft. 941 generates a repulsive force, and the inner walls on both sides of the limiting sleeve 9 are symmetrically provided with adjustment grooves 97, the end of the telescopic shaft 961 is located inside the adjustment groove 97 and slides with the inner limit, and the adjustment groove 97 includes a forward action area 971, an inclined rising area 972 connected to the forward action area 971, a return area 973 connected to the inclined rising area 972, a descending area 974 connected to the return area 973 and the forward action area 971, and a guide plate body 975. The side of the guide plate body 975 close to the forward action area 971 is an inclined surface, and the side located at the intersection of the forward action area 971 and the inclined rising area 972 is a right-angle surface.
[0039] Step 2: During each locking operation, when the magnetic shaft 941 moves with the hinged seat 5 and other components, the force-applying magnetic plate 21 will generate a repulsive force on the magnetic shaft 941, and the magnetic shaft 941 drives the sliding plate frame 94 to slide within the limiting sleeve 9. During the sliding of the sliding plate frame 94, the fixed frame 95 on one side of the sliding plate frame 94 will drive the action plate frame 96 to move synchronously. In the initial state, the action plate frame 96 is in contact with the force-bearing plate frame 93, and the telescopic shaft 961 on one side of the action plate frame 96 is located at the initial end of the forward action area 971 (i.e., the end of the descending area 974);During each movement of the sliding plate frame 94, the action plate frame 96 applies an action force to the force plate frame 93, and under the action of the force plate frame 93, the piston rod frame 92 squeezes the lubricating oil in the injection mechanism 91, so that the lubricating oil flows out of the discharge pipe of the injection mechanism 91 and drips into the slot 81. It should be noted that during the movement of the telescopic shaft body 961 in the forward action area 971, the telescopic shaft body 961 passes through the inclined surface of the guide plate body 975 and moves to the intersection of the inclined rising area 972 and the forward action area 971. When the magnetic shaft body 941 is away from the action plate frame 941, the action plate frame 96 applies an action force to the force plate frame 93, and then under the action of the force plate frame 93, the piston rod frame 92 squeezes the lubricating oil in the injection mechanism 91, so that the lubricating oil flows out of the discharge pipe of the injection mechanism 91 and drips into the slot 81. When the force magnetic plate 21 is not subjected to the repulsive force, the magnetic shaft 941 and the sliding plate frame 94 return to the initial state under the action of the reset spring 98, and then the fixed frame 95 drives the action plate frame 96 to move in the opposite direction. During the reverse movement of the action plate frame 96, the telescopic shaft 961 on one side of the action plate frame 96 is acted upon by the right-angled surface of the guide plate body 975 and moves along the trajectory of the inclined rising area 972. At this time, the action plate frame 96 makes a corresponding position adjustment. When the telescopic shaft 961 moves to the end of the inclined rising area 972, the action plate frame 96 will move in the reverse direction. In the process, it will not contact with the force-bearing plate frame 93. When the telescopic shaft body 961 moves to the end of the return area 973 (that is, the initial end of the descending area 974), the action plate frame 96 is located above the adjacent force-bearing plate frame 93. The action plate frame 96 moves along the trajectory of the descending area 974 under the action of gravity, that is, it finally moves to the initial end of the forward action area 971. Then, when the action plate frame 96 continues to move, it will continue to act on the adjacent force-bearing plate frame 93. Repeat the above operation, and then during each movement of the magnetic shaft body 941, the action plate frame 96 will apply a force to the force-bearing plate frame 93, and each time The piston rod frame 92 has a certain forward distance, and each movement of the piston rod frame 92 will act on the lubricating oil in the injection mechanism 91, so that the lubricating oil in the injection mechanism 91 drips into the slot 81 along the discharge pipe, thereby playing a lubricating role. Through the structural design of the present invention, the pin shaft 8 can be lubricated during each operation, effectively reducing the friction between the pin shaft 8 and the connecting hinge rod 4, avoiding the pin shaft 8 from being worn due to friction, thereby effectively improving the service life of the bolt 6 and avoiding the bolt 6 from bending and deformation due to uneven force or impact load. ;
