Has the advantages that:
1. the left box and the right box of the invention can rotate around the right gear and the left gear respectively, and can rotate to the direction parallel to the middle box and also can rotate to the direction vertical to the middle box, when the left box and the right box rotate to the direction parallel to the middle box, the left box and the right box are in an opening rotating state at the same time, when the left box and the right box rotate to the state vertical to the middle box, the left box and the right box are in a closed state, and at the moment, the left box lock hole and the right box lock hole can lock the left box and the right box together, the left gear and the right gear are mutually meshed, so the left box and the right box can be separated and folded at the same time, thus the invention can be opened and closed at any side, the operation is convenient, when the invention is used, the left box and the right box are separated, the mechanism greatly increases the use space of the invention, 3 boxes can be used, each box is divided into, when the medical examination box is used, medical articles can be managed according to hospital bed classification, and can also be managed and stored according to medicine classification, the inside of the right box is divided into 2 parts, the right box container at the lower part can be used for collecting garbage, and the right box container at the upper part can be used for placing large examination equipment.
2. When the left box is closed, the matching gear rolls on the surface of the half gear and rotates in a matching manner with the gear to drive the rack gear to rotate, the rack gear rotates to drive the shifting rod to move towards the rear part of the left box, when the left box is opened, the matching gear rolls on the surface of the half gear in a reverse direction and rotates in a matching manner with the gear to drive the rack gear to rotate in a reverse direction, and the rack gear rotates to drive the shifting rod to move towards the front part of the left box. The first connecting rod, the second connecting rod and the third connecting rod are connected with the second box, the third box and the left box, the first connecting rod, the second connecting rod and the third connecting rod form a parallel connecting rod structure, so that the second box and the third box can move back and forth in a direction parallel to the bottom surface of the left box, when the left box is closed, the deflector rod moves towards the rear part of the left box, the deflector rod drives the fourth connecting rod to rotate, the arc-shaped groove pushes the fourth shaft to move back, the second box and the third box can be vertically aligned and collected in the left box, when the left box is opened, the deflector rod is driven to move towards the front part of the left box, the deflector rod drives the fourth connecting rod to rotate, the arc-shaped groove pushes the fourth shaft to move forward, the second box and the third box can be vertically staggered and unfolded outside the left box, when the left box is opened, the second box and the third box can be simultaneously unfolded, common articles can be conveniently taken, the first box is an independent container and can be manually opened and closed, to prevent some of the less common items.
3. When the left box and the right box are opened relatively, the left gear and the right gear are meshed through the insections and rotate relatively, and the matched gear rolls on the smooth surface of the half gear without insections, so that the second box and the third box cannot be drawn out from the left box in the process of opening the left box and the right box relatively, the drawing-out of the second box and the third box has time delay relative to the opening of the left box and the right box, and the collision between the second box and the right box in the process of opening the left box and the right box is avoided. When the half gear wheel rotates to be meshed with the gear grains of the matching gear, the rack gear pushes the driving rod to slide outwards, so that the second box and the third box are withdrawn outwards, and the relative angle between the right box and the left box cannot cause the collision between the second box and the right box.
4. The fourth shaft is clamped in the arc-shaped groove, the fourth shaft slides in the arc-shaped groove relatively while the fourth connecting rod rotates in the process of drawing the second box and the third box, the interaction speed of the fourth shaft can be reduced by the arc structure of the fourth connecting rod relative to the linear structure, the drawing speed of the second box and the third box is further reduced, the second box and the third box are prevented from colliding with the right box when the left box and the right box are opened relatively, and the situation that articles contained in the second box and the third box are toppled and collided due to the fact that the drawing speed of the second box and the third box is too high is reduced.
5. The first box sliding block is clamped in the first box sliding groove, so that the first box is centered in the left box and cannot collide when being drawn out. A box slides on a box slider, prescribes a limit to a box slip orbit, reduces a box and takes place the card pause in the slip in-process on a box slider, makes a box be difficult for colliding with left incasement wall, No. two boxes at the pull in-process, reduces No. three connecting rods simultaneously, a connecting rod, No. two connecting rods because of a box skew and No. two box collisions cause the possibility of deformation, and then increased No. three connecting rods, a connecting rod, No. two connecting rods at the stationarity of rotation in-process.
6. When the medical box is used, all the articles are classified and stored in different containers according to the medical articles required each time, the middle box, the left box and the right box are folded and locked together, the medical box can be conveniently pushed and moved to a specified place, then the left box or the right box is rotated, and the middle box, the left box and the right box are unfolded to be used.
