[0002] The electric control cabinet is filled with various switchgear, measuring instruments, protective electrical appliances and auxiliary equipment. Among them, only the circuit breaker needs daily operation. The rest of the equipment can be viewed through the transparent observation window on the electric control cabinet or directly displayed on the display screen on the electric control cabinet door. In the prior art, when operating the circuit breaker, it is necessary to open the cabinet door, operate the circuit breaker, and then close the cabinet door. The inconvenience of this operation is that, on the one hand, a large number of circuit devices are exposed after opening the cabinet door, which brings potential risks to safety management. On the other hand, it is necessary to open and close the cabinet door, which requires many steps.

[0021] See also Figure 1-5 The utility model provides an embodiment: an external switch device for an electric control cabinet door, comprising a fixed seat 1 for fixing on the inner side of a cabinet door 10, a movable seat 2 arranged inside the fixed seat 1, and a clamping mechanism 3 for clamping the movable seat 2 at the inner center of the fixed seat 1. In this embodiment, the fixed seat 1 is a cubic structure with one end open, and the movable seat 2 inside the fixed seat 1 is a cubic structure with a cylindrical groove arranged horizontally inside. The circuit breaker switch 9 can rotate freely inside. The fixed seat 1 is provided with a plurality of mounting holes 101, and the mounting holes 101 can be fixed on the inner side of the cabinet door 10 of the electric control cabinet by bolts. The mounting position corresponds to the circuit breaker switch 9. When the cabinet door 10 is closed, the circuit breaker switch 9 can be directly inserted into the movable seat 2.

[0022] One end of the movable seat 2 extends to the outside of the fixed seat 1 and is provided with a flared section 201. The flared section 201 is specifically a truncated cone structure whose inner diameter gradually increases along the axial direction from the open end of the movable seat 2, so that the circuit breaker switch 9 can be inserted into the inside of the movable seat 2 when the cabinet door 10 is closed.

[0023] The clamping mechanism 3 includes clamping plates 301 respectively arranged at four sides of the fixed seat 1 and first springs 302 respectively pushing the clamping plates 301 to move closer to the center of the fixed seat 1. The four clamping plates 301 are respectively fitted with the four side walls of the movable seat 2 to realize elastic clamping and limiting of the movable seat 2. When the installation position of the fixed seat 1 is not accurate and slightly offset, it can be automatically guided under the guidance of the flared section 201, so that the circuit breaker switch 9 can be accurately inserted into the inside of the movable seat 2.

[0024] A driving disk 4 is rotatably arranged inside the movable seat 2 through a slide rail, and the driving disk 4 matches the circuit breaker switch 9. Specifically, mutually matching protrusions and slots are arranged on opposite sides of the driving disk 4 and the circuit breaker switch 9. When the protrusion is inserted into the slot, the driving disk 4 and the circuit breaker switch 9 can rotate synchronously. A rotating shaft 401 is arranged at the center of one end of the driving disk 4 away from the flared section 201, and the rotating shaft 401 extends to the outside of the fixed seat 1 and is fixed with a knob 7.

[0025] A connecting rod 202 is fixed at the center of one end of the movable seat 2 near the rotating shaft 401, and a limiting plate 6 is fixed on the connecting rod 202. The limiting plate 6 and the fixed seat 1 clamp the cabinet door 10 in the middle. The fixed seat 1 and the cabinet door 10 are both provided with a clearance hole 5 whose size is larger than the connecting rod 202. The size of the limiting plate 6 is larger than the size of the clearance hole 5. A through hole is provided in the middle of the connecting rod 202 to accommodate the free rotation of the rotating shaft 401. When assembling, the connecting rod 202 passes through the clearance holes 5 on the fixed seat 1 and the cabinet door 10 and then extends to the outside of the cabinet door 10. The limiting plate 6 A mounting ring 601 is fixed in the middle of one side, and the limit plate 6 abuts against the outside of the cabinet door 10. The mounting ring 601 is then fixed to the connecting rod 202 by bolts to play the role of axial limit. The limit plate 6 can also block the clearance hole 5. The rotating shaft 401 then passes through the central through hole of the connecting rod 202 and extends to the outside of the cabinet door 10, and then is fixedly connected with the knob 7. Specifically, it can be fixedly connected by bolts. When working, the knob 7 is rotated to drive the drive disk 4 to rotate through the rotating shaft 401, and then drive the circuit breaker switch 9 to rotate, so as to realize the switch of the circuit breaker outside the door;

[0026] In one embodiment, a sealing gasket is provided at one end of the limit plate 6 close to the cabinet door 10 to improve the sealing type of the connection. For an electric control cabinet with low sealing requirements, the sealing gasket can be replaced with a ball bearing, which is rollingly connected to the cabinet door 10, so that the limit plate 6 can move synchronously with the movable seat 2.

[0027] In one embodiment, a limiting mechanism 8 is provided on the knob 7, and the limiting mechanism 8 includes two slide seats 801 provided on the knob 7 for radial sliding along the knob 7, a second spring 802 that pushes the two slide seats 801 to move away from the center of the knob 7, and a slide rod 803 fixed to one end of the slide seat 801 near the limiting plate 6, the slide rod 803 extends to the outside of the knob 7, and a bar-shaped through hole is provided on the knob 7 to accommodate the radial movement of the slide rod 803 along the knob 7, and a plurality of slide grooves 804 corresponding to the slide rod 803 are provided on the limiting plate 6, and the slide grooves 804 include an arc groove 8041 accommodating the slide rod 803 to rotate with the rotating shaft 401 as the center and respectively provided on the inner side of the slide rod 803. The limiting grooves 8042 at both ends of the arc groove 8041 are located on the side of the arc groove 8041 away from the center of the knob 7. Under normal conditions, under the elastic support of the second spring 802, the two slide bars 803 are inserted into the limiting grooves 8042. When the circuit breaker switch 9 needs to be adjusted, the two slide seats 801 are gently pinched toward the middle to compress the second spring 802, and the two slide bars 803 are separated from the limiting grooves 8042. The slide seat 801 is then rotated to rotate the slide bar 803 in the arc groove 8041. After the rotation is in place, the slide seat 801 is released, and the two slide bars 803 are automatically inserted into the limiting grooves 8042 at the other end under the elastic action of the second spring 802.

[0028] The slide bar 803 is a cylindrical structure, and the slide bar 803 is rotatably connected to the slide seat 801, so that the slide bar 803 and the slide groove 804 are rollingly connected to reduce wear.

[0029] Working principle: When in use, close the cabinet door 10, and the circuit breaker switch 9 is inserted into the interior of the movable seat 2 through the flared section 201. The size of the flared section 201 is larger than the size of the movable seat 2. During the plug-in process, when the installation position of the fixed seat 1 is offset, the circuit breaker switch 9 can be accurately inserted into the interior of the movable seat 2 by squeezing different first springs 302, and the protrusions on the driving disk 4 are inserted into the grooves on the circuit breaker switch 9. The driving disk 4 and the circuit breaker switch 9 can rotate synchronously. When in use, rotate the knob 7 outside the door to drive the driving disk 4 to rotate through the rotating shaft 401, and then realize the switching of the circuit breaker switch 9.
