[0006] In a possible implementation manner, the length of the locking rod is greater than the length of the trigger rod.

[0007] In a possible implementation manner, the locking rod of one locking member is superimposed on the locking rod of another locking member.

[0008] In a possible implementation, a limit block is provided on the fixing frame, and the limit block is located below the locking rod disposed near the mold base and contacts the lower end surface of the locking rod to limit the rotation of the locking member.

[0009] In a possible implementation, the upper end surface of the mold base is provided with a limiting opening corresponding to the two locking members.

[0010] In a possible implementation, the mold base includes two bottom plates and a support plate; the two bottom plates are arranged in parallel and spaced apart; the support plate is arranged above the two bottom plates and fixedly connected to the bottom plates; the limiting opening and the fixing frame are both located on the support plate.

[0022] See also Figures 1 to 7 The self-locking cabinet base provided by the present invention is now described. A self-locking cabinet base includes a mold base 1, a fixing frame 2 and a locking member 3; an electrical cabinet 4 is used to support the mold base 1; the fixing frame 2 is fixedly installed on the mold base 1, and the fixing frame 2 corresponds to the limit opening 41 on the bottom of the electrical cabinet 4, and both ends of the fixing frame 2 are provided with a rotating shaft 22; the number of the locking members 3 is two, both are installed on the fixing frame 2, and respectively correspond to the two rotating shafts 22; the locking member 3 includes a locking rod 31 and a trigger rod 32 installed at the opposite end of the locking rod 31, and the locking rod 31 rotates with the rotating shaft 22. The trigger rod 32 and the locking rod 31 are arranged at an angle and extend upward; the distance between the upper ends of the two trigger rods 32 is greater than the size of the limit opening 41, and the distance between the locking rod 31 and the rotating shaft 22 is greater than the distance between the rotating shaft 22 and the hole wall on one side of the limit opening 41 close to the limit opening 41; the electrical cabinet 4 moves from top to bottom until it contacts the two trigger rods 32, the two trigger rods 32 move downward and drive the two locking rods 31 to move upward, and the ends of the two locking rods 31 away from the trigger rods 32 pass through the limit opening 41 to act on the electrical cabinet 4.

[0023] Compared with the prior art, the self-locking cabinet base provided in the present embodiment has a self-locking cabinet base provided in the present invention. When in use, since the fixing frame 2 is provided on the mold base 1 and the two locking members 3 are both installed on the fixing frame 2, after the electrical cabinet 4 is placed on the mold base 1, the two locking members 3 lock the cabinet body of the electrical cabinet 4, thereby fixing the electrical cabinet 4; since the locking rod 31 on the locking member 3 is rotatably connected with the rotating shaft 22 on the fixing frame 2, and the trigger rod 32 provided at one end away from the locking rod 31 is provided at an angle with the locking rod 31 , and the trigger rod 32 extends upward; at the same time, the distance between the upper ends of the two trigger rods 32 is greater than the size of the limit opening 41, and the distance between the locking rod 31 and the rotating shaft 22 is greater than the distance between the rotating shaft 22 and the hole wall on the side of the limit opening 41 close to the locking rod 31, and the distance between the rotating shaft 22 and the hole wall on the side of the limit opening 41 close to the electrical cabinet 4 after installation is less than the distance between the rotating shaft 22 and the trigger rod 32; therefore, when the locking member 3 is used to lock the electrical cabinet 4, the forklift moves the electrical cabinet 4 to the top of the mold base 1 and makes the limit opening 41 on the bottom surface of the electrical cabinet 4 close to the two limit openings. When the locking pieces 3 correspond to each other, the electrical cabinet 4 is controlled to descend. As the electrical cabinet 4 moves, the bottom surface of the electrical cabinet 4 contacts and squeezes the trigger rod 32. The trigger rod 32 moves downward and drives the locking rod 31 connected to the rotating shaft 22 to rotate, so that the end of the locking rod 31 away from the trigger rod 32 passes through and acts on the electrical cabinet 4, thereby locking the electrical cabinet 4. In this way, the bottom support of the self-locking cabinet body is arranged under the electrical cabinet 4, and the two locking pieces 3 are used to make the electrical cabinet 4 contact and squeeze the locking piece 3 with the help of the gravity of the electrical cabinet 4. The trigger rod 32 on the mold base 1 causes the locking rods 31 on the two locking members 3 to rotate in opposite directions, and then pass through the limit opening 41 to act on the electrical cabinet 4, thereby locking the electrical cabinet 4 to prevent the electrical cabinet 4 from moving freely on the mold base 1; when the electrical cabinet 4 needs to be unlocked, it is only necessary to control the electrical cabinet 4 to move upward, thereby driving the locking rod 31 to rotate in the opposite direction, thereby unlocking the electrical cabinet 4; the self-locking cabinet base has a small size, a simple structure, convenient and flexible installation, and a low cost, and can achieve rapid self-locking and unlocking, greatly improving production efficiency.
