[0019] like Figures 1 to 4 As shown, a drawer unit of the utility model that can realize the emergency unlocking function includes a drawer unit body 1 and a door panel 2 installed in front of the drawer unit body 1. The drawer unit body 1 is assembled by two side panels, a bottom panel and a rear side panel through rivets. The two side panels are a first side panel 4 and a second side panel 6. The left side of the door panel 2 is hinged to the first side panel 4. Specifically, a hinge 3 is welded on the left side of the door panel 2, and the other end of the hinge 3 is fixed to the first side panel 4 to form a hinged structure. A locking mechanism for locking and unlocking the door panel 2 is provided between the right side of the door panel 2 and the second side panel 6.

[0020] In this embodiment, the locking mechanism includes a buckle 5, a bolt 7, an axle pin 8 and a spring 9. The buckle 5 is welded on the right side of the door panel 2, that is, the welded parts of the drawer door panel 2 include a hinge 3 and a buckle 5, which are integrated and welded on the door panel 2 to provide rotation and buckle locking functions. The front end of the second side panel 5 has an outwardly bent edge 11, and a through hole is opened on the edge 11. The bolt 7 is in the shape of a folded plate, and one side of it has an opening, and the opening and the through hole overlap to form a locking hole 12 for locking the buckle 5. The other side of the bolt 7 is provided with a vertical long hole 13. A slide post 14 is provided at the front end of the second side panel 6. The slide post 14 is located in the long hole 13 and can slide relatively along the long hole 13 when the bolt 7 moves up and down. A vertical axle pin 8 is provided at the lower part of the front end of the second side panel 6. The bottom end of the bolt 7 has a horizontal fold 16. The axle pin 8 is sleeved in the spring 9 and passes through the horizontal fold 16 of the bolt 7 upward.

[0021] A through emergency unlocking hole 15 is provided on the door panel 2, in which a plastic plug cap 10 is detachably installed. The emergency unlocking hole 15 corresponds to the transverse folding edge 16 of the door bolt 7 so that a tool inserted into the emergency unlocking hole 15 can drive the door bolt 7 to move downward and unlock by pressing down the transverse folding edge 16.

[0022] The working principle of the utility model is:

[0023] When the drawer unit is located at the cabinet connection position, the buckle 5 is engaged with the door latch 7, that is, the buckle 5 is engaged in the engagement hole 12, and the door latch 7 is fastened under the elastic force of the spring 9 installed on the axle pin 8. At this time, the door panel 2 is in a locked state, ensuring the protection level of the drawer unit.

[0024] When emergency unlocking is required, take out the plastic plug cap 10 set in the emergency unlocking hole 15 on the door panel 2, insert an electrician's screwdriver into the emergency unlocking hole 15, press the horizontal folding edge of the bolt 7 on the shaft pin 8, and the spring 9 installed on the shaft pin 8 is shortened by force, and the clamping relationship between the bolt 7 and the buckle 5 fails. At this time, the door panel 2 can be opened. The emergency unlocking function can be realized when the drawer unit is in the connection position, and electrical debugging, device reset, and circuit breaker electrical and mechanical faults can be eliminated, providing convenient and efficient operation and maintenance.

[0025] The implementation methods of the present invention are not limited to this. According to the above content of the present invention, in accordance with the common technical knowledge and customary means in the field, without departing from the above basic technical ideas of the present invention, the locking mechanism of the present invention also has other implementation methods. Therefore, the present invention can also make other various forms of modifications, replacements or changes, all of which fall within the scope of protection of the present invention.
