[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] A mechanical interlocking mechanism for a high current socket, such as Figure 1-Figure 10 As shown, the mechanical interlocking mechanism is applied in the electrical box 1, and the mechanical interlocking mechanism includes a female socket 2 and a male plug 3. The female socket 2 is fixedly installed at one end of the electrical box 1. A joystick 11 is rotatably provided in the electrical box 1. The joystick 11 is connected to the switch in the electrical box 1 to control the opening and closing of the switch. The joystick 11 is a rectangular structure, and a handle 12 is fixedly connected to the upper end of the joystick 11 to control the rotation of the joystick 11.

[0022] A cover shell 13 is fixedly mounted on the electrical box 1 , and an operating rod 11 passes through the cover shell 13 , and the operating rod 11 is rotatably disposed on the cover shell 13 , and a guide hole is opened on one side of the cover shell 13 .

[0023] A dust cover 21 is rotatably installed at one end of the female socket 2, and a mounting plate 28 is fixedly installed at the other end. The mounting plate 28 is fixedly connected to the electrical box 1, and a rectangular groove 29 is provided on the mounting plate 28. An arc shell 22 is fixedly provided on the female socket 2. The inner wall of the arc shell 22 is an arc structure, and a mounting groove 23 is provided in the arc shell 22. A mounting shaft 26 is fixedly provided in the mounting groove 23. A limiting claw 24 is rotatably provided on the mounting shaft 26. One end of the limiting claw 24 is rotatably connected to the mounting shaft 26, and a chamfer 27 is provided on the outer side of the other end.

[0024] A torsion spring 25 is mounted on the mounting shaft 26, and two ends of the torsion spring 25 are respectively connected to the arc shell 22 and the limiting claw 24 for supporting the limiting claw 24. A locking rod 4 and a locking rod 2 5 are arranged on one side of the limiting claw 24. The locking rod 4 is located above the locking rod 2 5, and the locking rod 4 and the locking rod 2 5 horizontally penetrate the rectangular groove 29. The locking rod 4 and the locking rod 2 5 are slidably connected to the electrical box 1, one end of the locking rod 4 moves horizontally above the limiting claw 24, and the other end is rotatably connected to a connecting piece 15, and a connecting rod 41 is fixedly provided on the connecting piece 15, and the connecting rod 41 is rotatably connected to the end of the locking rod 4.

[0025] The connecting piece 15 is fixedly connected to the operating rod 11, and a connecting piece 2 14 is arranged below the connecting piece 15. A limiting groove 10 is provided on one side of the connecting piece 2 14, and a U-shaped piece 51 is provided on the other side. The U-shaped piece 51 is slidably connected to the guide hole, and the limiting groove 10 is engaged with the operating rod 11 to limit the operating rod 11. The U-shaped piece 51 is fixedly connected to the locking rod 2 5, and a spring 52 is sleeved on the U-shaped piece 51. One end of the spring 52 is fixedly connected to the inner wall of the cover shell 13, and the other end is fixedly connected to the locking rod 2 5. The elastic force of the spring 52 makes the locking rod 2 5 maintain the tendency to move in the direction of the limiting claw 24.

[0026] One end of the locking rod 5 away from the spring 52 is located below the limiting claw 24 , and the locking rod 5 is fixedly connected to the connecting member 14 .

[0027] The male plug 3 includes a plug body 31, which is connected to the female socket 2 in a plug-in manner. A protrusion 32 is fixedly provided on the plug body 31, and the protrusion 32 is slidably connected to the inner wall of the arc shell 22. When the protrusion 32 moves to the inside of the mounting groove 23, one end of the protrusion 32 will push the locking rod 25 to move toward the cover shell 13, compressing the spring 52. At this time, the protrusion 32 is located below the limiting claw 24, and the limiting claw 24 contacts the other end of the protrusion 32 to block the protrusion 32 from being pulled out, locking the protrusion 32, so that the male plug 3 is tightly connected to the female socket 2 to avoid loosening.

[0028] Here’s how it works: Before using the device, the externally connected male plug 3 is inserted into the female socket 2. When the protrusion 32 on the male plug 3 slides into the arc shell 22, the locking rod 25 is pushed up to make the locking rod 25 slide on the cover shell 13, so that the spring 52 is compressed. At this time, the limiting groove 10 on the connecting member 14 is disengaged from the joystick 11. At this time, the limit on the joystick 11 is released, and then the handle 12 on the rotating electrical box 1 is operated. The handle 12 and the joystick 11 are rotated 90 degrees to turn on the current in the electrical box 1, so that the components in the electrical box 1 can be opened and work normally.

[0029] When the operating lever 11 rotates, the connecting member 15 is driven to rotate, and the connecting member 15 pushes the locking rod 4 connected thereto to slide into the female socket 2, so that the end of the locking rod 4 away from the connecting member 15 moves to the top of the limiting claw 24, so that the locking rod 4 contacts the upper surface of the limiting claw 24, and the locking rod 4 slides on the upper surface of the limiting claw 24 and presses the limiting claw 24, so that the limiting claw 24 rotates on the mounting shaft 26. Figure 8 Rotate clockwise as shown, so that the limit claw 24 blocks the protrusion 32. At this time, the locking rod 4 is located on the limit claw 24, blocking the limit claw 24 from rotating upward, preventing the male plug 3 from being pulled out of the female socket 2, which helps to lock the male plug 3 in the female socket 2 and ensure stable operation of the equipment.

[0030] When the handle 12 is closed, the locking rod 1 4 is removed from the limiting claw 24, and the male plug 3 can be pulled out at this time to disconnect the connection between the male plug 3 and the female socket 2. When the male plug 3 is pulled out, the spring 52 will push the locking rod 2 5 to move until the limiting groove 10 on the connecting piece 2 14 is connected with the operating rod 11, fixing the operating rod 11 to prevent the handle 12 from being opened by mistake, affecting the next connection of the male plug 3, causing abnormal power-on, avoiding damage to the components in the electrical box 1, and improving the safety of use.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
