Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-9, the technical solution adopted by the present invention is as follows: a misoperation prevention locking mechanism for a low-voltage power distribution cabinet comprises a cabinet body 1. A cabinet door 2 is installed on one side of the cabinet body 1, and a switch button 4 is installed on the upper surface of the cabinet body 1. The upper surface of the cabinet body 1 is provided with a square through hole, and a baffle 3 is arranged inside the cabinet body 1. The baffle 3 is arranged in the square through hole in a sliding mode. The cabinet door 2 is in transmission connection with the baffle 3 through a transmission mechanism, and drives the baffle 3 to slide up and down in the square through hole.

The transmission mechanism comprises a slide block 15, a ball screw pair, a gear 17, a rack 18 and the like.

A sliding block 15 is installed on one side of the cabinet door 2, a sliding groove 14 is formed in one side of the cabinet body 1, and the sliding block 15 is located in the sliding groove 14. The cabinet is characterized in that a ball screw 12 is installed on the inner wall of the cabinet body 1, and a nut 13 is fixedly installed on one side of the cabinet door 2. Balls are provided between the ball screw 12 and the nut 13. The ball screw 12, the nut 13, and the balls constitute a ball screw pair. The inner wall of the cabinet body 1 is provided with a rolling column 6, the ball screw 12 is in transmission connection with the rolling column 6 through a transmission belt 5, and a gear 17 is fixed on the rolling column 6. A rack 18 is fixedly arranged on one side of the baffle 3, and the gear 17 is meshed with the rack 18.

The lower portion of the baffle 3 is provided with clamping grooves 22 on two sides, the control mechanism comprises two groups of control components, and each group of control components is respectively matched with the corresponding clamping grooves 22. Each set of control components comprises a limit plate 19, a clamping plate 11, an elastic element, a magnetic element and the like. The two sets of control assemblies operate simultaneously and cooperate with the card slot 22.

The cabinet body 1 is internally provided with two limiting plates 19 which are respectively arranged corresponding to the two sides of the baffle 3. The limiting plate 19 is provided with a first limiting groove 20 and a second limiting groove 21 in an up-and-down symmetry manner. Two rotating shafts 10 are fixedly arranged on the inner wall of the cabinet body 1. Each rotating shaft 10 is rotatably connected with a rotating block 9, and two clamping plates 11 are fixedly mounted at one end of each rotating block 9 and respectively arranged corresponding to the corresponding limiting plates 19.

The clamping plate 11 is a U-shaped structure, and two ends of the clamping plate are respectively disposed toward the first limiting groove 20 and the second limiting groove 21.

The inner wall of the cabinet body 1 is provided with an elastic part connected with the upper end of the clamping plate 11. The resilient member comprises a spring 7. Two fixed columns 8 are installed on one side of the inner wall of the cabinet body 1, and the two fixed columns 8 are respectively arranged correspondingly to the corresponding limiting plates 19. The fixing column 8 is fixedly connected with the upper part of the clamping plate 11 through a spring 7, and the fixing column 8 is arranged corresponding to the first limiting groove 20.

The inner wall of the cabinet body 1 is provided with a magnetic part which is matched with the lower end of the clamping plate 11. The magnetic member comprises an electromagnet 16. Two electromagnetism pieces 16 are installed to the inner wall one side of the cabinet body 1, electromagnetism piece 16 corresponds to the setting of second spacing groove 21. The two electromagnetic blocks 16 are respectively arranged corresponding to the corresponding limit plates 19. The lower end of the clamping plate 11 is a magnetic body.

The working principle is as follows:

when in use, the electromagnetic block 16 is electrified by controlling the switch button 4. The electromagnetic block 16 adsorbs the lower end of the clamping plate 11, so that the lower end of the clamping plate 11 is separated from the clamping groove 22 and the second limiting groove 21. The card board 11 is located in the first limiting groove 20, and the card board 11 always abuts against one side of the baffle 3 through the first limiting groove 20. The cabinet door 2 is pushed, and the sliding block 15 enables the cabinet door 2 to slide and open through the sliding groove 14. The cabinet door 2 drives the screw 13 to move. The nut 13 moves to drive the ball screw 12 to rotate, thereby driving the rolling post 6 to rotate through the transmission belt 5. The rotation of the rolling post 6 drives the gear 17 to rotate, so that the baffle 3 is moved upwards through the rack 18. When the baffle 3 moves upwards to a certain position, the upper end of the clamping plate 11 enters the clamping groove 22 of the baffle 3 through the first limiting groove 20 for limiting. When the baffle 3 is applied with downward force, the gear 17 and the rack 18 can be prevented from being damaged due to excessive force by the clamping plate 11. The catch plate 11 serves to protect the gear 17 and the rack 18 and to stabilize the position of the shutter 3 after it has been lifted.

When baffle 3 rises and fixes baffle 3 through cardboard 11, can be divided into two parts with the upper surface of cabinet body 1, maintenance of equipment can be placed to partly, and another part sets up control button 4. Too much maintenance equipment is piled up, and in order to avoid bumping into control button 4, baffle 3 has played the effect of blockking that maintenance equipment bumped control button 4 by mistake.

When the electromagnetic block is used, the electromagnetic block 16 is powered off, the upper end of the clamping plate 11 is separated from the clamping groove 22, and the lower end of the clamping plate 11 is inserted into the second limiting groove 21 and is abutted to the baffle 3. At this time, the door 2 is closed, and the slider 15 slides and closes the door 2 through the slide groove 14. The cabinet door 2 drives the screw 13 to move, the screw 13 moves to drive the ball screw 12 to rotate, and therefore the rolling column 6 is driven to rotate through the transmission belt 5. The rotation of the rolling post 6 drives the gear 17 to rotate, so that the baffle 3 is moved downwards through the rack 18. When the clamping groove 22 at the lower part of the baffle 3 is aligned with the second limiting groove 21, the clamping plate 11 passes through the second limiting groove 21 and is inserted into the clamping groove 22, so that the baffle 3 is clamped by the clamping plate 11.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
