Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, specifically to a distribution box door lock device. Background Technology

[0002] Distribution boxes play a central role in power distribution, distributing power from the main line to multiple branches and controlling the current through main switches, circuit breakers, or fuses to meet diverse power demands. This distribution method not only ensures the safety of power supply but also improves the efficiency of power resource utilization. Distribution box doors must be locked to ensure personnel safety and prevent electric shock accidents caused by direct contact with exposed wires, especially when there are exposed wires inside the distribution box. Furthermore, distribution boxes and switch boxes should be managed and used by certified electricians; non-electrical personnel are strictly prohibited from operating and managing them. Existing door lock devices have poor security and their internal structures are prone to rust, leading to difficulty in opening and closing the doors and requiring regular manual lubrication, which is cumbersome. In view of these issues, this case was developed through in-depth research. Utility Model Content

[0003] The purpose of this utility model is to provide a distribution box door lock device to solve the problem mentioned in the background art that the existing distribution box door lock device does not have high security and self-lubrication.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a distribution box door lock device, comprising a box body, an oil hole, and a mounting hole. A door is movably mounted on one side of the box body via a hinge, and a control panel is mounted on one end of the door body. A fingerprint recognition module is mounted below one end of the control panel. A mounting rod is movably mounted on the inner wall of the door body via a bearing. A moving block is mounted on the outer side of the mounting rod, and a mounting hole is provided on the inner side of the moving block. A welding seat is mounted on the inner wall of the box body below the moving block. A second servo motor is mounted on the inner wall of the door body. An oil cavity is provided on the inner side of the door body, and an oil hole is provided below the oil cavity. An oil plug is mounted on the inner side of the oil hole, and a sealing gasket is mounted on the outer wall above the oil plug.

[0005] Preferably, a first servo motor is installed on the inner wall of one end of the welding seat, and the output end of the first servo motor is connected to a lead screw through a drive shaft. A movable sleeve is threaded on the outer wall of the lead screw, and the top end of the movable sleeve is fixedly connected to the movable block.

[0006] Preferably, a locking block is connected to the outer wall of one end of the mounting rod, and a locking groove that mates with the locking block is provided on the outer wall of one end of the movable block.

[0007] Preferably, the output end of the second servo motor is connected to a drive gear via a drive shaft, and a driven gear is installed on the outer wall of one end of the mounting rod, forming a meshing transmission structure between the driven gear and the drive gear.

[0008] Preferably, a rotating rod is movably mounted on the inner wall of the door above the drive gear via a bearing, and one end of the rotating rod is connected to a pressing block.

[0009] Preferably, the top of the oil plug is connected to a top plate, and dampers are installed on both sides of the bottom end of the top plate, and a return spring is installed on the outer wall of each damper.

[0010] Preferably, sprockets are mounted on the outer walls of the second servo motor drive shaft and the rotating rod, and a chain is driven between the outer walls of the sprockets.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model provides a second servo motor, a chain, and an oil plug. The second servo motor drives the chain to rotate the rotating rod, which rotates the extrusion block to the top to extrude the oil plug, causing the sealing gasket to move upward. Then, the lubricating oil in the oil chamber flows downward through the gap between the oil plug and the oil hole. The lubricating oil then lubricates the drive gear and the driven gear, making the door opening and closing smoother and solving the problem of not having a self-lubricating structure.

[0013] This utility model provides a fingerprint recognition module, a first servo motor, and a second servo motor. Personnel information is identified by pressing their fingers on the fingerprint recognition module. After successful identification, the staff can operate the control panel to open the door. The first servo motor rotates the lead screw, which, through threaded engagement, moves the moving sleeve and moving the moving block to the right, displacing the locking block from the slot. Then, the second servo motor rotates the drive gear, which meshes with the driven gear, causing the mounting rod to rotate simultaneously, aligning one end of the mounting rod with the mounting hole. The first servo motor then reverses direction, causing the moving sleeve and moving block to the left, removing the mounting rod from the moving block. The door can then be opened for internal maintenance, thus solving the problem of poor security. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figures 1-5 A distribution box door lock device includes a box body 4, an oil hole 16 and a mounting hole 25. A door body 5 is movably installed on one side of the box body 4 via a hinge, and a control panel 9 is installed at one end of the door body 5. A fingerprint recognition module 27 is installed below one end of the control panel 9. An installation rod 3 is movably installed on the inner wall of the door body 5 via a bearing. A moving block 11 is installed on the outer side of the installation rod 3, and a mounting hole 25 is provided on the inner side of the moving block 11. A welding seat 13 is installed on the inner wall of the box body 4 below the moving block 11. A second servo motor 8 is installed on the inner wall of the door body 5. An oil cavity 6 is provided on the inner side of the door body 5, and an oil hole 16 is provided below the oil cavity 6. An oil plug 17 is installed on the inner side of the oil hole 16, and a sealing gasket 19 is installed on the outer wall above the oil plug 17.

[0022] The inner wall of one end of the welding seat 13 is equipped with a first servo motor 2, and the output end of the first servo motor 2 is connected to a lead screw 1 through a drive shaft. The outer wall of the lead screw 1 is threaded with a movable sleeve 12, and the top end of the movable sleeve 12 is fixedly connected to the movable block 11.

[0023] A locking block 26 is connected to the outer wall of one end of the mounting rod 3, and a slot 22 that mates with the locking block 26 is provided on the outer wall of one end of the moving block 11.

[0024] The output end of the second servo motor 8 is connected to the drive gear 7 via the drive shaft, and the driven gear 10 is installed on the outer wall of one end of the mounting rod 3, and the driven gear 10 and the drive gear 7 form a meshing transmission structure.

[0025] Specifically, such as Figure 1 , Figure 3 and Figure 5 As shown, when using this structure, staff members can identify their personal information by pressing their fingers on the fingerprint recognition module 27. After successful identification, staff members can operate the control panel 9 to open the door 5. The first servo motor 2 rotates the lead screw 1, which, through threaded engagement, causes the moving sleeve 12 to move the moving block 11 to the right, moving the locking block 26 away from the slot 22. Then, the second servo motor 8 rotates the drive gear 7, which meshes with the driven gear 10, causing the mounting rod 3 to rotate simultaneously, making one end of the mounting rod 3 parallel to the mounting hole 25. Then, the first servo motor 2 reverses its operation, causing the moving sleeve 12 to move the moving block 11 to the left, moving the mounting rod 3 out of the moving block 11. The door 5 can then be opened for internal maintenance, ensuring high security.

[0026] Example 2: A rotating rod 14 is movably mounted on the inner wall of the door body 5 above the drive gear 7 via a bearing, and one end of the rotating rod 14 is connected to a pressing block 15;

[0027] The top of the oil plug 17 is connected to the top plate 20, and dampers 18 are installed on both sides of the bottom of the top plate 20. The outer wall of the dampers 18 is equipped with a return spring 21.

[0028] The second servo motor 8 has sprockets 24 mounted on the outer walls of its drive shaft and rotating rod 14, and a chain 23 is installed between the outer walls of the sprockets 24 for transmission.

[0029] Specifically, such as Figure 1 and Figure 2 As shown, when using this structure, the second servo motor 8 works to drive the chain 23 to rotate the rotating rod 14 at the same time. The squeezing block 15 rotates to squeeze the upper oil plug 17, causing the sealing gasket 19 to move upwards at the same time. Then, the lubricating oil in the oil chamber 6 flows downwards through the gap between the oil plug 17 and the oil hole 16. The lubricating oil then lubricates the drive gear 7 and the driven gear 10, making the door 5 open and close more smoothly.

[0030] Working principle: When using this device, the staff first presses their finger on the fingerprint recognition module 27 to identify the personnel information. After the identification is correct, the staff can operate the control panel 9 to control the door 5 to open.

[0031] Implementation steps for the first innovation point:

[0032] Step 1: The first servo motor 2 is used to rotate the lead screw 1. The threaded engagement causes the moving sleeve 12 to drive the moving block 11 to move to the right, so that the locking block 26 moves away from the slot 22.

[0033] Step 2: Then, the second servo motor 8 is used to make the drive gear 7 rotate. The drive gear 7 meshes with the driven gear 10, making the mounting rod 3 rotate at the same time, so that one end of the mounting rod 3 is parallel to the mounting hole 25. Then, the first servo motor 2 is used to reverse the operation, so that the moving sleeve 12 drives the moving block 11 to move to the left, so that the mounting rod 3 is moved out of the moving block 11. Then the door 5 can be opened to carry out internal maintenance work.

[0034] Implementation steps for the second innovation point:

[0035] The second servo motor 8 drives the chain 23 to rotate the rotating rod 14, which in turn rotates the squeezing block 15 to squeeze the upper oil plug 17, causing the sealing gasket 19 to move upwards. Then, the lubricating oil in the oil chamber 6 flows downwards through the gap between the oil plug 17 and the oil hole 16. The lubricating oil lubricates the drive gear 7 and the driven gear 10, making the door 5 open and close more smoothly.
