In the invention, if the tool cabinet is lifted, but the cabinet door 2 is not closed, at this time, the straight surface on one side of the third inclined surface 77 on the limiting block 7 is already in a state of being matched with the clamping groove 11 on the cabinet door 2, but the second inclined surface 76 is also in a state of being matched with the cabinet door 2, so that when the cabinet door 2 is manually closed, the cabinet door 2 can also make the limiting block 7 move downwards by extruding the second inclined surface 76, and then the cabinet door 2 is closed and limited by the limiting mechanism 10.

According to the swing plate 5 designed by the invention, when the cabinet door 2 is opened, the swing plate 5 can swing downwards relative to the corresponding partition plate 6 to open through gear transmission, so that a user can conveniently take or place objects, and if the cabinet door 2 is closed, the swing plate 5 can be upwards closed relative to the corresponding partition plate 6, so that a heavy object placed on the partition plate 6 can not slide down to damage the cabinet door 2 when the user closes the cabinet door 2 and lifts the tool cabinet to move.

The specific working process is as follows: when the tool cabinet designed by the invention is used, after the tool cabinet is placed on the ground, the internal thread sleeves 67 on the two sides are pushed by the ground to drive the corresponding internal screw rods 64 to move upwards relative to the corresponding external thread sleeves 66 and the corresponding external screw rods 65, the internal screw rods 64 move upwards to drive the mounting plate 50 to move upwards, the mounting plate 50 moves upwards to drive the third toothed plate 49 to move upwards, the third toothed plate 49 moves upwards to drive the tenth gear 48 to rotate, the tenth gear 48 rotates to drive the first toothed plate 38 to move downwards, the first toothed plate 38 moves downwards to drive the connecting rod 14 to move downwards, and the connecting rod 14 moves downwards to drive all the clamping mechanisms 13 to move downwards; so that the blocking mechanism 13 is matched with an avoiding port 78 formed on the swing plate 5; the swinging plate 5 can not be limited by the clamping mechanism 13 in the opening process.

The mounting plate 50 moves upwards on the other hand to drive the fourth toothed plate 51 to move upwards, the fourth toothed plate 51 moves upwards to drive the eleventh gear 52 to rotate, the eleventh gear 52 rotates to drive the fifth toothed plate 80 to move downwards, the fifth toothed plate 80 moves downwards to drive the eighteenth gear 59 to rotate, the eighteenth gear 59 rotates to drive the third rotating shaft 44 to rotate, the third rotating shaft 44 rotates to drive the ninth gear 47 to rotate, the ninth gear 47 rotates to drive the second toothed plate 46 to move downwards, the second toothed plate 46 moves downwards to drive the connecting column 45 to move downwards, the connecting column 45 moves downwards to drive the corresponding limiting mechanism 10 to move downwards, and the limitation of the straight surface on one side of the third inclined surface 77 on the limiting block 7 in the limiting mechanism 10 on the cabinet door 2 is released; meanwhile, the third rotating shaft 44 rotates to drive the thirteenth gear 54 to rotate, the thirteenth gear 54 rotates to drive the fourth gear 35 to rotate, the fourteenth gear 55 rotates to drive the seventeenth gear 58 to rotate, the seventeenth gear 58 rotates to drive the sixteenth gear 57 to rotate, and the sixteenth gear 57 rotates to drive the winding wheel 60 to rotate; if the cabinet door 2 is in a state of being closed and limited by the limiting mechanism 10, the winding wheel 60 rotates to pull one of the two elastic ropes to extend, the elasticity of the elastic rope is increased, and if the cabinet door 2 is manually opened at the moment, the limiting of the limiting mechanism 10 on the cabinet door 2 is removed, then the cabinet door 2 is automatically opened under the tension of the elastic rope after the limiting of the limiting mechanism 10 is lost, and the opened state is kept under the tension of the elastic rope after the cabinet door 2 is opened.

In the process of opening the cabinet door 2, the door shaft 12 rotates to drive the fifteenth gear 56 to rotate, the fifteenth gear 56 rotates to drive the third gear 34 to rotate, the third gear 34 rotates to drive the second rotating shaft 33 to rotate, the second rotating shaft 33 rotates to drive the fourth gear 35 to rotate, the fourth gear 35 rotates to drive the fifth gear 36 to rotate, the fifth gear 36 rotates to drive the sixth gear 37 to rotate, the sixth gear 37 rotates to drive the seventh gear 39 to rotate, the fourth gear 35 rotates to drive the eighth gear 40 to rotate, the eighth gear 40 rotates to drive the first rotating shaft 16 to rotate, the first rotating shaft 16 rotates to drive the first gear 15 to rotate, the first gear 15 rotates to drive the corresponding second gear 17 to rotate, and the second gear 17 rotates to drive the corresponding swing shaft 79 to rotate; the swing shaft 79 swings to drive the swing plate 5 to swing open downwards.

When the tool cabinet is lifted, when the cabinet door 2 is automatically closed, the lower side of one end of the cabinet door 2 facing the cabinet body 1 can extrude the third inclined surface 77 on the limiting block 7 in the corresponding limiting mechanism 10, so that the limiting block 7 moves downwards into the corresponding limiting shell 9, when the cabinet door 2 extrudes the limiting block 7 to close, the limiting block 7 in the limiting mechanism 10 can gradually move into the clamping groove 11 on the cabinet door 2 under the action of the corresponding first spring 8 to limit the cabinet door 2, in this state, the limiting is the opening limiting of the limiting block 7 on the cabinet door 2 through the second inclined surface 76 on the limiting block, because the included angle between the second inclined surface 76 and the adjacent side surface on the limiting block 7 is 150 degrees, the second inclined surface 76 is extruded in the opening process of the cabinet door 2, so that the limiting mechanism 10 has a certain limiting function on the opening of the corresponding cabinet door 2 after the cabinet door 2 is closed, if the cabinet door 2 is to be opened, a pulling force for movement needs to be applied to the cabinet door 2. The reason why the angle between the third inclined surface 77 and the adjacent side surface of the limiting block 7 is designed to be 120 degrees is that the resistance between the cabinet door 2 and the corresponding limiting mechanism 10 is reduced in the closing process, and the cabinet door 2 is relatively easy to close. When the cabinet door 2 is opened, the cabinet door 2 is manually pulled, so that the cabinet door 2 is separated from the limit of the corresponding limit mechanism 10, after the limit mechanism 10 loses the limit on the cabinet door 2, the cabinet door 2 can be automatically opened through the tension of the elastic rope, and the cabinet door can be maintained in an open state under the acting force of the elastic rope; according to the analysis, when the tool cabinet designed by the invention is normally placed on the ground and needs to be carried, if the cabinet door 2 is not limited by the limiting mechanism 10, namely when the cabinet door is not closed, the cabinet door 2 is certainly in an open state under the action of the elastic rope and is kept; when the tool cabinet is carried, a worker can clearly recognize that the cabinet door 2 needs to be closed, and after the tool cabinet with steps is closed, the limiting block 7 on the limiting mechanism 10 moves upwards, the straight surface with the third inclined surface 77 can be in contact fit with the clamping groove 11 on the cabinet door 2, the opening of the cabinet door 2 is completely limited, and the cabinet door 2 cannot be opened due to shaking in the carrying process; and traditional tool cabinet, when cabinet door 2 was in the closure state, the unable accurate judgement cabinet door 2 of staff was the lock state or only was in the closure state, if just be in the closure state, appeared rocking then in handling, cabinet door 2 has probably been opened once more, influences the transport. According to the invention, after the tool cabinet is carried to a place and put down, the limiting mechanism 10 moves downwards, the second inclined surface 76 on the limiting block 7 in the limiting mechanism 10 is matched with the clamping groove 11 on the cabinet door 2 again, and a worker can open the cabinet door 2 by exerting force. Make the transport of tool cabinet convenient through such design, need not special lock cabinet door 2, also need not worry cabinet door 2 and open because of rocking, influence the transport.
