DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figures 1 to 5 When the cabinet door 2 is opened, the locking mechanism 21 of the ring network cabinet is unlocked, and the locking mechanism 22 of the ring network cabinet is unlocked.

[0024] The locking assembly includes a rotating unit and a second locking block 7, the second locking block 7 is fixedly connected to the rotating block 6, a locking groove 8 is opened on one side of the second locking block 7, and a limit block 9 is fixedly connected to the locking groove 8 by a spring. When working, the second locking block 7 is provided with a limit block 9 fixed by a floor spring, so that the first locking block 4 can be automatically locked when the cabinet door 2 is pushed. When the cabinet door 2 needs to be opened, it only needs to drive the second locking block 7 to rotate through the rotating unit, so that the limit block 9 can be located in the sliding groove 5, and then the cabinet door 2 can be pulled. The operation is convenient and convenient for the staff to carry out maintenance.

[0025] The rotating unit includes a circular plate 10, which is fixedly connected to the side wall of the second positioning block 7. A handle 11 is fixedly connected to the circular plate 10. When working, the staff can rotate the handle 11 to drive the circular plate 10 to rotate, thereby driving the second positioning block 7 to rotate, thereby driving the limiting block 12 to rotate, so that the limiting block 9 is located in the sliding groove 5, and the cabinet door 2 can be pulled to open, which is easy to operate.

[0026] A limiting block 12 is fixedly connected to the cabinet door 2, a fixing rod 13 is fixedly connected to the cabinet door 2, a first hook 14 is fixedly connected to the fixing rod 13, a second hook 15 is fixedly connected to the second blocking block 7, and an elastic band 16 is connected to the first hook 14 and the second hook 15. During operation, the first hook 14 and the second hook 15 are connected by the elastic band 16, so that after the staff turns the handle 11 to drive the second blocking block 7 to rotate, the position of the second blocking block 7 can be automatically restored by the elastic force of the elastic band 16, and the position is limited by the setting of the limiting block 12, so that when the staff closes the cabinet door 2 again, they only need to push the cabinet door 2.

[0027] The contact surface between the first locking block 4 and the limiting block 9 is an arc surface 17. During operation, by setting the contact surface between the first locking block 4 and the limiting block 9 as the arc surface 17, when the staff closes the cabinet door 2, the limiting block 9 can be locked more smoothly, thereby achieving a closing effect.

[0028] One end of the limit block 9 is an inclined surface 18. During operation, the limit block 9 has an inclined surface 18, so that when the staff closes the cabinet door 2, the inclined surface 18 of the limit block 9 can contact the arc surface 17 of the first locking block 4, thereby enabling smoother buckling.

[0029] Working principle: The first locking block 4 is locked by the locking component arranged in the rotating block 6 connected to the cabinet body 1 through rotation, so that the cabinet door 2 can be closed and opened more conveniently, so as to solve the problem that the traditional locking mechanism is generally unlocked by a key, but when rainwater enters the keyhole and causes rust inside, it is difficult to open the cabinet door 2 and carry out maintenance, which poses a serious safety hazard. The mechanical locking does not require the use of auxiliary operations such as keys during operation. For the sake of safety, a locking mechanism of the ring network cabinet is needed to meet people's needs. A limit block 9 fixedly connected to a floor spring is arranged in the second locking block 7, so that the first locking block 4 can be automatically locked when the cabinet door 2 is pushed. When the cabinet door 2 needs to be opened, it is only necessary to drive the second locking block 7 to rotate through the rotating unit, so that the limit block 9 can be located in the sliding groove 5, and then the cabinet door 2 can be pulled. It is easy to operate and convenient for the staff to carry out maintenance. The staff can drive the circular door 2 to rotate the handle 11. The shaped plate 10 rotates, thereby driving the second positioning block 7 to rotate, thereby driving the limiting block 12 to rotate, so that the limiting block 9 is located in the sliding groove 5, and the cabinet door 2 can be pulled to open. The operation is convenient. The first hook 14 and the second hook 15 are connected by the elastic band 16, so that after the staff turns the handle 11 to drive the second positioning block 7 to rotate, the orientation of the second positioning block 7 can be automatically restored by the elastic force of the elastic band 16, and the orientation is limited by the setting of the limiting block 12, so that when the staff closes the cabinet door 2 again, they only need to push the cabinet door 2. The contact surface of the first positioning block 4 and the limiting block 9 is an arc surface 17, so that when the staff closes the cabinet door 2, the limiting block 9 can be more smoothly positioned, thereby achieving the closing effect. The limiting block 9 has an inclined surface 18 at one end, so that when the staff closes the cabinet door 2, the inclined surface 18 of the limiting block 9 can contact the arc surface 17 of the first positioning block 4, so that it can be buckled more smoothly.
