the utility model provides an electrical cabinet of in-band lock structure, includes electrical cabinet body 1 and preceding side articulated cabinet door 2 thereof, and articulated department is installed to the medial surface of cabinet door 2 and keeps away from and turn over tongue lock 3. An arc-shaped lug 30 is welded on one side of the rotating tongue lock 3, an unlocking column 4 is arranged right above the rotating tongue lock 3, an inner lock column 5 is fixed on the inner side of the top of the electrical cabinet body 1 and right above the unlocking column 4, and the shape of the lug 30 is beneficial to propping the unlocking column 4 to slide on the lug 30 and propping the inner lock column 5 upwards so as to separate from the limiting sleeve. The top end and the middle section of the unlocking column 4 are sleeved with a limiting sleeve 40. A rack 41 is welded on one side of the inner side surface of the cabinet door 2, which is positioned on the upper limiting sleeve 40. The outer side of the inner lock column 5, which is close to the bottom, is provided with a limiting table 50, a spring 51 is sleeved above the limiting table 50, and the outer diameter of the limiting table 50 is larger than the major diameter of the spring 51. The top of the inner lock column 5 is sleeved with a fixed sleeve 52, and the top end of the inner lock column 5 is in threaded connection with a nut, so that the inner lock column 5 is prevented from slipping from the fixed sleeve 52. A through groove 53 is formed in one side of the bottom of the inner lock cylinder 5, and a retractable positioning pin 6 is arranged right behind the through groove 53. The side of the front half section of the positioning pin 6 is engaged with a toothed column 60, one side of the toothed column 60 is also engaged with the toothed column 60, the toothed column 60 far away from the positioning pin 6 can be engaged with a rack 41, when the cabinet door 2 is closed, the rack 41 can contact the toothed column 60 far away from the positioning pin 6, so that the toothed column 60 with one side rotates at the same time, finally, the positioning pin 6 can be driven to retreat to be separated from the through groove 53, and the inner locking column 5 pushes against the limiting table 50 to move downwards to abut against the top end of the unlocking column 4 under the elastic force of the spring 51. The middle of the positioning pin 6 is provided with a boss 62, a compression spring 63 is sleeved on one side of the boss 62 and positioned at the rear half section of the positioning pin 6, and the toy of the boss 62 is larger than the major diameter of the compression spring 63. The rear end of the positioning pin 6 is sleeved with a guide sleeve 64, a convex column is arranged at the top of the guide sleeve 64 and is welded with the top of the electrical cabinet body 1, and therefore the positioning pin 6 is stably hung.

Further, the position-limiting sleeve 40 is welded to the inner side of the cabinet door 2, so that the unlocking column 4 is pressed against the lug 30 to stably move vertically.

Specifically, the top outside of the inner lock cylinder 5 is provided with threads, and the fixing sleeve 52 is welded on the top inside of the electrical cabinet body 1, so that the inner lock cylinder 5 is stably suspended. Interior lock post 5 can with the cooperation of pegging graft of top stop collar 40 to interior lock post 5 blocks the inner wall of regulator cubicle body 1 and cabinet door 2, makes the unable outside pulling in top of cabinet door 2.

Specifically, the positioning pin 6 may be inserted into the through groove 53, so that the positioning pin 6 does not interfere when the cabinet door 2 is closed. The side surface of the front half section of the positioning pin 6 is provided with a tooth groove with the same structure as the rack 41.

In addition, the suspension post 61 has been cup jointed to the inside of column 60, and the ring has all closely been cup jointed in the upper and lower end that the outside of suspension post 61 just is located column 60, and suspension post 61 top and 1 top welding of regulator cubicle body are makeed the column 60 to hang steadily.

It should be added that a pin is inserted through the rear end of the positioning pin 6 and the length of the pin is greater than the width of the guide sleeve 64, so as to prevent the positioning pin 6 from slipping out of the guide sleeve 64.

The utility model discloses an electrical cabinet with internal lock structure is when opening, insert supporting key through the front end at lock 3, rotate lock 3 ninety degrees again, make the horizontality turn to vertical state, simultaneously, unlock post 4 can slide and the rebound along lug 30 side along with the rotation of lock 3, the top until unlock post 4 flushes with the stop collar 40 top of top, at this moment, interior lock post 5 just by in the ejecting stop collar 40 of unlock post 4, along with shifting up of interior lock post 5, make logical groove 53 be close to locating pin 6 until the coincidence, it makes the 6 front ends of locating pin insert logical groove 53 to push up boss 62 under the spring action of pressure spring 63, make interior lock post 5 not downwards protrusion, interfere with the stop collar 40 of top when avoiding closing cabinet door 2, outwards pull open cabinet door 2 again and can open. When the cabinet door 2 is closed, the rack 41 contacts the toothed column 60 far away from the positioning pin 6 first, so that the rack rotates while the toothed column 60 with one side rotates, and finally the positioning pin 6 can be driven to retreat to be separated from the through groove 53, the inner lock column 5 pushes the limiting table 50 to move downwards under the action of the elastic force of the spring 51 to push against the top end of the unlocking column 4, at the moment, the rotating key enables the rotating tongue lock 3 to rotate to be in a horizontal state, the unlocking column 4 moves downwards due to the self weight and the elastic force of the spring 51, and meanwhile, the inner lock column 5 is pushed by the spring 51 to be inserted into the limiting sleeve 40 above, so that the top of the cabinet door 2 is limited by the inner lock column 5 to be locked.

The foregoing shows and describes the general principles, essential features, and advantages of the invention.
