By turning on the power supply circuit, the power supply supplies power to the power-consuming equipment. By turning off the power supply circuit, the power supply stops supplying power to the power-consuming equipment, thereby realizing power control of the power-consuming equipment. The electrical operation box is a supporting equipment for the light high-voltage test transformer. It has superior performance, multiple functions, small size, light weight, reliable use, beautiful appearance, and convenient operation and maintenance.

[0003] The electrical operation box is usually closed with a five-protection padlock. The door cannot be opened without authorization. However, the operator may forcibly dismantle the door and bypass the five-protection lock to perform forced operations. In view of this situation, it is necessary to prevent the operator from forcibly dismantling the operation box door. In addition, there are many equipment points that need to be monitored on site, and it is impossible to monitor them all by manpower. Therefore, it is necessary to provide a cabinet door anti-dismantling device to promptly remind the operator and operating personnel of violations. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides a cabinet door anti-disassembly device.

[0016] The beneficial effects of the utility model are:

[0017] The alarm body of the utility model is installed on the operating box through a mounting base. When the operator violently disassembles the cabinet door, the alarm must be removed before operation. When the two alarm bodies are relatively displaced, the locking connector will be deformed. The deformed locking connector contacts the conductive ring, thereby generating current in the detection circuit, thereby controlling the alarm to perform an alarm operation. The alarm device automatically alarms when it is dismantled, thereby achieving the purpose of reminding the on-site personnel.

[0018] The utility model provides a locking mechanism in the alarm body, which can be locked with the latch on the mounting seat, so that the two alarm bodies can be installed on the operation box through the mounting seat, and the alarm body and the mounting seat can be locked and connected through the electromagnet on the alarm body, so that the two alarm bodies can be removed conveniently, which is convenient for normal cabinet door opening operations.

[0019] The alarm body of the utility model can be fixed on the operating box by screws, etc., so that the alarm body and the mounting base form a firm and non-detachable structure.

[0032] like Figure 2 , 3 As shown in FIG. 4 , the cabinet door anti-disassembly device includes two alarm bodies 3, which are connected by a locking connector 4. The locking connector 4 is an aluminum rod, a copper rod or an iron rod. Each alarm body 3 is also provided with a mounting seat 2, on which a latch 21 is provided. The latch 21 is provided with an arc groove. The alarm body 3 is provided with a latch hole 31 and a receiving cavity 32 that cooperate with the latch 21. The latch hole 31 and the receiving cavity 32 are connected. The connection between the latch hole 31 and the receiving cavity 32 is provided with an arc portion that cooperates with the steel ball 33. The receiving cavity 32 is provided with a locking mechanism that cooperates with the latch 21. The alarm body 3 is provided with a socket 36 for installing the locking connector 4. The locking connector 4 is threadedly connected to the mounting ring 7. The locking connector 4 is fixed in the socket 36. A conductive ring 37 is fixed in the socket 36. The jack 36 includes a small diameter section 361 and a large diameter section 362. The small diameter section 361 is threadedly connected to the locking connector 4, and the conductive ring 37 is fixed on the inner wall of the large diameter section 362. The inner diameter of the conductive ring 37 is clearance-matched with the outer diameter of the locking connector 4. The conductive ring 37 and the locking connector 4 are connected in series in the circuit. In normal state, the conductive ring 37 and the locking connector 4 are in a short-circuit state.

[0033] like Figure 5 As shown, the locking mechanism includes a plurality of steel balls 33, a push plate 34 and a reset spring 35. The steel balls 33, the push plate 34 and the reset spring 35 are sequentially arranged in the accommodating chamber 32 from top to bottom. The steel balls 33 are preferably arranged at three locations. The push plate 34 is provided with a push plate hole that cooperates with the latch 21, and the push plate hole and the latch 21 are clearance-matched. In normal state, the plurality of steel balls 33 are located near the arc portion under the action of the reset spring 35 and the push plate. When the latch 21 is inserted into the latch hole 31 and the accommodating chamber 32, the arc-shaped groove on the latch 21 is engaged with the steel balls 33, thereby fixing the latch 21. The alarm body 3 is fixed on the mounting seat 2 through the cooperation of the locking mechanism and the latch 21. The alarm body 3 is also provided with an electromagnet 6 that cooperates with the steel balls 33, and the electromagnet 6 is arranged on the side opposite to the position of the accommodating chamber 32. With remote control or mobile terminal control, the locking mechanism is unlocked by using the electromagnet 6, so that the alarm body 3 can be easily removed from the mounting base 2. A sealing plate 5 is also provided at the bottom of the alarm body 3, and the sealing plate 5 is welded and fixed to the alarm body 3. One side of the sealing plate 5 is provided on the alarm body 3, so that one side of the accommodating cavity 32 is hollowed out, so that the locking mechanism in the accommodating cavity 32 is easy to install.

[0034] like Figure 5As shown, two radial support members 39 are also provided in the jack, and the radial support members 39 are respectively provided at the two ends of the conductive ring 37, and the radial support members 39 are foam sleeves or rubber rings. The radial support members 39 are used to limit the radial positions of the two ends of the locking connector 4. In normal state, the ends of the locking connector 4 are not in contact with the conductive ring 37. When the positions of the two alarm bodies move, the locking connector 4 is deformed and bent, and the ends of the locking connector 4 and the conductive ring 37 are bent, thereby connecting the locking connector 4 and the current detection circuit where the conductive ring 37 is located, so that it is convenient for the control module to control the alarm to perform the alarm operation.

[0035] Each alarm body 3 is also provided with a battery, a control module and an alarm, and the battery is electrically connected to the control module, the alarm and the electromagnet 6. The control module is connected in series in the current detection circuit, and the control module detects the current of the current detection circuit, thereby controlling the alarm to perform an alarm operation.

[0036] like Figure 6 As shown, the mounting base 2 is provided with a plurality of screw holes 23, and the plurality of screw holes 23 are countersunk holes. The mounting base 2 is fixed to the operation box 1 through the screw holes 23 and screws. The screw holes need to be pre-opened on the operation box 1. This installation method is safer. The mounting base 2 can also be fixed to the operation box 1 by pasting. The pasting needs to be firm. This method is more convenient.

[0037] Working process and principle: Figure 1 As shown, when installing the cabinet door anti-disassembly device, a screw hole can be pre-opened on the operation box 1, the mounting seat 2 is fixed on the operation box 1 by screws, and then the two alarm bodies 3 are connected by the locking connector 4, and then the pin 21 of the mounting seat 2 is inserted into the jack 36, and fixed by the locking mechanism in the accommodating cavity 32, so as to complete the installation of the cabinet door anti-disassembly device. When the two alarm bodies 3 rotate under the action of external force, the locking connector 4 is deformed under the action of the two alarm bodies 3, and the end of the locking connector 4 is deformed and contacts the conductive ring 37, so that the detection circuit of the locking connector 4 and the conductive ring 37 is connected, and the control module detects the current and controls the alarm to perform the alarm operation. When the locking connector 4 is an aluminum rod or a copper rod, the material of the aluminum rod and the copper rod is relatively soft. When the positions of the two alarm bodies 3 move relatively, the aluminum rod and the copper rod are radially deformed, thereby contacting the conductive ring 37, so that a current is generated in the detection circuit, and the control module detects the current and controls the alarm to alarm. When the locking connector 4 is an iron rod, the middle part of the iron rod can be replaced with a steel wire rope, and the two ends of the iron rod are threadedly connected to the small diameter section 361 of the socket 36. When the positions of the two alarm bodies 3 move relative to each other, the steel wire rope part radially deforms and moves to contact the conductive ring 37, so that current is generated in the detection circuit. The control module detects the current and controls the alarm to sound an alarm.
