DETAILED DESCRIPTION

[0030] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0031] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] See also Figure 1 , Figure 2 and Figure 3 The present embodiment provides a safety protection device for an electrical cabinet, including a cabinet body 10, a cabinet door 20, an unlocking knob 30, an indicating assembly 40, a box body 50, a lock pin 60 and a driving assembly 70. The cabinet door 20 is hingedly arranged on one side of the cabinet body 10. The cabinet door 20 is provided with a first slide groove 201. The box body 50 is fixedly installed on the inner wall of the cabinet door 20. The box body 50 is provided with a second slide groove 501 corresponding to the first slide groove 201. One end of the lock pin 60 extends to the inside of the box body 50, and the other end extends to the outside of the box body 50. The inner wall of the cabinet body 10 is provided with a lock hole (not shown in the figure) that matches the lock pin 60. The unlocking knob 30 is arranged on the inner wall of the cabinet body 10. On the outside of the cabinet door 20, one end of the unlocking knob 30 extends from the first slide groove 201 and the second slide groove 501 to the inside of the box body 50, and a dial 301 is provided on the side of the unlocking knob 30 away from the cabinet door 20, and a certain scale of the dial 301 is an unlocking scale. One end of the indicating component 40 extends to the side of the unlocking knob 30 away from the cabinet door 20, and the other end passes through the unlocking knob 30 and extends to the inside of the box body 50. The driving component 70 is installed in the inside of the box body 50. When the unlocking knob 30 slides down along the first slide groove 201 and the second slide groove 501, the driving component 70 is used to drive the indicating component 40 to rotate.

[0033] When the cabinet door 20 is closed on one side of the cabinet body 10, one end of the lock pin 60 is inserted into the lock hole on the inner wall of the cabinet body 10, thereby locking the cabinet door 20. When it is necessary to open the cabinet door 20 to inspect and maintain the parts inside the cabinet body 10, the staff can push the unlocking knob 30 downward, and the unlocking knob 30 slides downward along the first slide groove 201 and the second slide groove 501. At the same time, the driving component 70 drives the indicating component 40 to rotate. When the unlocking knob 30 slides down to a certain position, the indicating component 40 rotates to a certain angle and points to the unlocking scale. At this time, the unlocking knob 30 slides down to the unlocking position, and then the staff twists the unlocking knob 30, and the unlocking knob 30 drives the lock pin 60 to move into the box body 50, and then withdraws from the lock hole, thereby releasing the locked state of the cabinet door 20. The staff can pull the unlocking knob 30, thereby driving the cabinet door 20 to rotate, thereby opening the cabinet body 10, and the staff enters the cabinet body 10 to inspect and maintain the parts.

[0034] See also Figure 2 and Figure 3 In one embodiment, a first rotating sleeve 302 is fixedly provided on a side of the unlocking knob 30 facing the cabinet door 20, and an end of the first rotating sleeve 302 away from the unlocking knob 30 passes through the first sliding groove 201 and the second sliding groove 501 and extends into the box body 50. A vertically distributed paddle 303 is fixedly provided on the circumferential side wall of the first rotating sleeve 302, and the paddle 303 is tangent to the first rotating sleeve 302. The lock pin 60 is located at one end of the box body 50. A connecting plate 601 is fixedly provided at one end, a notch 602 is opened on one side of the connecting plate 601, a guide shaft 603 is fixedly provided at the end of the connecting plate 602 away from the locking pin 60, a guide sleeve 502 is fixedly provided on the inner wall of the box body 50, the guide shaft 603 extends to the inside of the guide sleeve 502 at one end away from the connecting plate 602 and is connected to the inner wall of the guide sleeve 502 through a second elastic member 604, and the second elastic member 604 is used to provide elastic support for the guide shaft 603.

[0035] When it is necessary to open the cabinet door 20 to inspect and maintain the internal parts of the cabinet body 10, the staff will turn the unlocking knob 30 downward, and the unlocking knob 30 drives the rotating sleeve 301 to slide downward along the first slide groove 201 and the second slide groove 501, thereby driving the paddle 303 to move downward. During this process, the driving component 70 drives the indicating component 40 to rotate. When the indicating component 40 rotates to a certain angle and points to the unlocking scale represented by the dial 301, the unlocking knob 30 slides down to the unlocking position. At this time, the lower end of the paddle 303 extends into the notch 602, and then the unlocking knob 30 is turned. The unlocking knob 30 drives the first rotating sleeve 302 and the paddle 303 to rotate. When the paddle 303 rotates, it acts on the inner wall of the notch 602, thereby pushing the connecting plate 601 to pull the locking pin 60 so that the locking pin 60 moves When the box body 50 moves inside, one end of the lock pin 60 withdraws from the lock hole when the box body 50 moves, thereby releasing the locked state between the cabinet door 20 and the cabinet body 10. During the above process, the connecting plate 601 pushes the guide shaft 603 so that the guide shaft 603 moves toward the inside of the guide sleeve 502, and the second elastic member 604 is compressed by force; when the unlocking knob 30 passes through the unlocking position, the indicating assembly 40 rotates from the unlocking scale position. At this time, the paddle 303 and the first rotating sleeve 302 can pass through the notch 602 as a whole. At this time, the unlocking knob 30 is rotated again, and the unlocking knob 30 drives the paddle 303 to rotate. The paddle 303 cannot act on the inner wall of the notch 602, and thus cannot push the connecting plate 601 to move, that is, it cannot take one end of the lock pin 60 away from the lock hole, thereby preventing the cabinet door 20 from being opened for no reason and achieving the anti-theft purpose.

[0036] See also Figure 2 and Figure 3 In one embodiment, the indicating assembly 40 includes a pointer 401 and a second rotating sleeve 402, one end of the second rotating sleeve 402 extends to the side of the unlocking knob 30 away from the cabinet door 20 and is connected to the pointer 401, and the other end passes through the unlocking knob 30 and the first rotating sleeve 302 and extends to the inside of the box body 50, the pointer 401 and the second rotating sleeve 402 are perpendicular to each other, and the pointer 401 is distributed radially along the unlocking knob 30, the driving assembly 70 includes a rack 701 and a gear 702, the gear 702 is fixedly arranged on the outside of the second rotating sleeve 402, and the rack 701 is fixedly mounted on the inner wall of the box body 50 and meshes with the gear 702.

[0037] When the unlocking knob 30 drives the first rotating sleeve 302 to slide down the first sliding groove 201 and the second sliding groove 501, the unlocking knob 30 can also drive the second rotating sleeve 402 and the gear 702 to move downward as a whole. Through the meshing action of the gear 702 and the rack 701, the gear 702 drives the second rotating sleeve 402 to rotate, and then drives the pointer 401 to rotate on one side of the unlocking knob 30. When the pointer 401 rotates to a certain angle and points to the unlocking scale represented by the dial 301, the lower end of the paddle 303 just extends into the notch 602. The staff can turn the unlocking knob 30, and the unlocking knob 30 drives the first rotating sleeve 302 and the paddle 303 to rotate. The paddle 303 acts on the inner wall of the notch 602 to push the connecting plate 601 to move. The connecting plate 601 pulls the locking pin 60 so that one end of the locking pin 60 withdraws from the lock hole, thereby completing the unlocking of the cabinet door 20.

[0038] See also Figure 3 In one embodiment, a slide rail 503 is fixedly provided on the inner wall of the box body 50, a slider 505 is slidably provided on the slide rail 503, a support shaft 504 is fixedly provided on one side of the slider 505, and one end of the support shaft 504 away from the slider 505 extends to the inside of the second rotating sleeve 402 and rotates with the second rotating sleeve 402.

[0039] When the unlocking knob 30 drives the first rotating sleeve 302 to slide down along the first slide groove 201 and the second slide groove 501, the support shaft 504 drives the slider 505 to slide down synchronously along the slide rail 503. The support shaft 504 provides support for the second rotating sleeve 402, the first rotating sleeve 302 and the unlocking knob 30, thereby ensuring that the unlocking knob 30 can slide down smoothly.

[0040] See also Figure 3 and Figure 4 In one embodiment, a support plate 506 is fixedly provided on one side of the slider 504, and the support plate 506 extends to one side of the first rotating sleeve 302. The support plate 506 is connected to the first rotating sleeve 302 through a first elastic member 507, and the first elastic member 507 is used to provide elastic pulling force to the first rotating sleeve 302.

[0041] After the unlocking knob 30 is turned to drive the locking pin 60 to withdraw from the lock hole, the unlocking knob 30 can be pulled to drive the cabinet door 20 to rotate to open the cabinet body 10. Then the staff releases the unlocking knob 30, and the first elastic member 507 pulls the first rotating sleeve 302 to make the first rotating sleeve 302 rotate in the opposite direction, thereby driving the unlocking knob 30 to rotate in the opposite direction, thereby resetting the unlocking knob 30.

[0042] In one embodiment, the first elastic member 507 and the second elastic member 604 may be springs or metal springs, which are not limited herein.

[0043] In the embodiment of the present invention, when the cabinet door 20 is closed on one side of the cabinet body 10, one end of the lock pin 60 is inserted into the lock hole on the inner wall of the cabinet body 10, thereby locking the cabinet door 20. When the cabinet door 20 needs to be opened to inspect and maintain the components inside the cabinet body 10, the staff can turn the unlocking knob 30 downward, and the unlocking knob 30 slides downward along the first slide groove 201 and the second slide groove 501. At the same time, the driving component 70 drives the indicating component 40 to rotate. When the unlocking knob 30 slides down to a certain position, the indicating component 40 rotates to a certain angle and points to the unlocking scale. At this time, the unlocking knob 30 slides down to the unlocking position, and then the staff twists the unlocking knob 30, and the unlocking knob 30 drives the lock pin 60 to the box. The cabinet 10 is unlocked by rotating the unlocking knob 30, thereby preventing the cabinet door 20 from being opened at will.

[0044] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments.
