However, thieves may carry screwdrivers or other torque tools when stealing, so that the box door can be opened normally without sounding an alarm. Therefore, the above junction box has hidden dangers in terms of anti-theft. Utility Model Content

[0005] The utility model aims to provide an electrical junction box with an anti-disassembly alarm function, so as to solve the problem that the existing junction box has poor practicality due to the existence of anti-theft hidden dangers due to comprehensive anti-theft measures during use.

[0006] In order to achieve the above-mentioned purpose, the basic solution provided by the utility model is: an electrical junction box with an anti-dismantling alarm function, comprising a box body, a door panel is hinged on one side of the box body, a lock body mechanism is arranged in the door panel, a sealing mechanism for hiding the opening end of the lock body structure is arranged on the door panel, the sealing mechanism comprises a handle, a groove is arranged in the door panel, a baffle is slidably connected in the groove, two straight slots are arranged on one side of the door panel, the upper and lower ends of the handle respectively pass through the straight slots and are fixedly connected to the baffle, an alarm component is arranged on the inner wall of the box body, and one end of the lock body mechanism abuts against the alarm component.

[0007] The principle of the utility model is as follows: when the technician opens the door normally, he first slides the handle to one side, thereby driving the baffle to move, and then releasing the seal of the lock body mechanism, and then inserts the key into the lock body mechanism to make the lock body mechanism abut against one end of the alarm component and shrink, and then open the door panel. When it needs to be closed, first turn the door panel inward to completely close the door panel, and then turn the key clockwise to make one end of the lock body mechanism abut against the alarm component, and then slide the handle to the opposite direction to make the baffle completely block the position of the lock body mechanism.

[0008] When a thief opens the door, since the baffle seals the lock mechanism in the initial state, it is difficult for the thief to find the position of the lock mechanism, so the thief directly pulls the handle. While the handle drives the door panel to move, one end of the lock mechanism presses the alarm component, causing the alarm component to sound an alarm.

[0009] The beneficial effects of the utility model are as follows: by arranging the lock body mechanism and the alarm component, the device has a good anti-theft effect; the lock body mechanism is sealed by the baffle in the initial state, thereby preventing thieves from finding the position of the lock cylinder; when the handle is directly pulled, the handle drives the door panel to rotate, and the door panel drives the lock tongue to move, thereby causing the lock tongue to squeeze the alarm component, thereby causing the alarm component to sound an alarm, effectively preventing thieves from picking the lock.

[0011] Option three is a preferred option of option two. A spring rod is fixedly connected inside the moving block, and one end of the spring rod is fixedly connected to the lock tongue. The spring rod is arranged inside the moving block so that the lock tongue can bounce back to its original position when the door is closed.

[0012] Option 4 is a preferred option of Option 2, wherein the alarm assembly includes a second spring, and a telescopic part and an alarm switch are fixedly connected to the inner walls of the box body, respectively. The alarm switch is located inside the telescopic part, and the second spring is sleeved on the outer wall of the alarm switch. The two ends of the second spring are fixedly connected to the inner wall of the box body and the inner wall of the telescopic part, respectively, and the lock tongue abuts against the outer wall of the telescopic part.

[0013] Option 5 is a preferred option of Option 2, in which one side of the lock tongue is curved; setting a curved surface at one end of the lock tongue makes it easier for the lock tongue to retract and return to its original position when the door is closed.

[0014] Option six, which is a preferred option of the basic option, is that a base is provided at the bottom of the box; providing a base at the bottom of the box facilitates the secure placement of the box. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figures 1 to 6 As shown: an electrical junction box with an anti-dismantling alarm function, comprising a box body 1, a base 18 is fixedly connected to the bottom of the box body 1, a door panel 2 is hinged on one side of the box body 1, a lock body mechanism is movably connected inside the door panel 2, the lock body mechanism comprises a lock core 3, a tooth plate 5 and a moving block 7, a gear 4 is fixedly connected to the outer wall of the lock core 3, the gear 4 is meshed with the tooth plate 5, one end of the tooth plate 5 is fixedly connected to a first spring 6, the first spring 6 is fixedly connected to the inner wall of the door panel 2, a protrusion 17 is fixedly connected to the side wall of the tooth plate 5, a straight notch 15 is opened on the inner wall of the door panel 2, the protrusion 17 is slidably connected to the straight notch 15, the protrusion 17 is fixedly connected to the moving block 7, a lock tongue 8 is movably connected inside the moving block 7, a spring rod 9 is fixedly connected inside the moving block 7, one end of the spring rod 9 is fixedly connected to the lock tongue 8, and one side of the lock tongue 8 is curved.

[0024] A sealing mechanism for hiding the open end of the lock body structure is movably connected to the door panel 2, and the sealing mechanism includes a handle 10. A groove is opened in the door panel 2, and a baffle 11 is slidably connected in the groove. Two straight slots 16 are opened on one side of the door panel 2, and the upper and lower ends of the handle 10 respectively pass through the straight slot 16 and are fixedly connected to the baffle 11. An alarm component is fixedly connected to the inner wall of the box body 1, and the alarm component includes a second spring 13. A telescopic part 12 and an alarm switch 14 are respectively fixedly connected to the inner wall of the box body 1, and the alarm switch 14 is located in the telescopic part 12. The second spring 13 is sleeved on the outer wall of the alarm switch, and the two ends of the second spring 13 are respectively fixedly connected to the inner wall of the box body 1 and the inner wall of the telescopic part 12, and the lock tongue 8 abuts against the outer wall of the telescopic part 12.

[0025] The implementation method of this embodiment is as follows: when the technician opens the door normally, he first slides the handle 10 to one side, thereby driving the baffle 11 to move, and then releasing the seal of the lock cylinder 3, and then inserts the key into the lock cylinder 3 and rotates it counterclockwise, and the lock cylinder 3 drives the gear 4 to rotate, and the gear 4 drives the tooth plate 5 to move toward the first spring 6, and the tooth plate 5 drives the moving block 7 to move in the same direction, and the lock tongue 8 in the moving block 7 moves in the same direction, so that the lock tongue 8 and the telescopic member 12 are released from the abutment. Therefore, when the door panel 2 is opened normally, the alarm switch 14 will not be pressed. When it needs to be closed, the door panel 2 is first rotated inward. When the lock tongue 8 contacts the box body, the curved surface at one end of the lock tongue 8 is compressed inward until the door panel 2 is completely closed and then bounces back to its original position. Then the handle 10 is slid to the opposite side to make the baffle 11 completely block the position of the lock cylinder 3.

[0026] When a thief opens the door, since the baffle 11 seals the lock cylinder 3 in the initial state, it is difficult for the thief to find the position of the lock cylinder 3, and the thief directly pulls the handle 10. While the handle 10 drives the door panel 2 to move, the lock tongue 8 squeezes the telescopic member 12, so that the telescopic member 12 contacts and presses the alarm switch 14, and then the alarm switch 14 sounds an alarm. At the same time, the lock tongue 8 abuts against the telescopic member 12, making it impossible to open the door panel 2.

[0027] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
