Concrete parts of the present utility model are described

A, door leaf 1 are hollow structure (seeing Fig. 1, Fig. 2 and Fig. 3), and door leaf 1 evenly has four arc grooves near four jiaos of places, in the middle of the groove through hole is arranged, and the slot opening direction inwardly;

Totally four groups of b, door-opening mechanisms are installed on four jiaos of (see figure 1)s of holding about the door leaf both sides symmetrically;

C, every group of door-opening mechanism device comprise: hinge 2, sliding axle 3 (seeing Fig. 1 and Fig. 2).

Hinge 2: be fixed on the doorframe 8, be installed on doorframe 8 outsides symmetrically near four jiaos of places.The structure (see figure 6) of hinge 2, the back-moving spring 2.3 behind the preload make the rebound 2.7 of hinge compress doorframe 8, and the fixed head 2.1 of hinge has screw 2.4, is screwed on doorframe 8.Have wedge shape square hole 2.6 on the arc 2.2, the angle of wedge is less.

Sliding axle 3: be fixedly installed in for a short time in the door leaf 1, be subjected to the restriction of slideway 10 (see figure 1) that can only horizontally slip.The structure (see figure 7) of this sliding axle 3; Front end is that voussoir 3.1 (angle of wedge is very little) equates with the angle of wedge of wedge shape square hole 2.6, the centre is a cylindrical section 3.2, end is thin cylindrical end 3.3, cylindrical section 3.2 is hinged by pin 3.4 and connecting rod 6, thin cylindrical end 3.3 is set with compression spring 7, compression spring 7 one ends and cylindrical section 3.2 offset, and the other end is fixed on the door leaf.

D, handle 5 have two groups, about each one group be symmetrically distributed in door leaf about 1 middle part position (seeing Fig. 1, Fig. 8) on the upper side;

E, unidirectional anti-reverse mechanism have two groups, and left and right symmetrically is distributed in the inner (see figure 1) of door leaf.

F, every group of unidirectional anti-reverse mechanism device comprise as the lower member (see figure 3).

Pinion gear mechanism 4 (see figure 9)s: be movably installed in the door leaf 1, pinion 4.4 can slide up and down and can rotate along self circular shaft 4.2 under the restriction of the shrinkage pool on the door leaf wall; Cylinder-shaped compression spring 4.3 props up the boss at pinion 4.4 end faces and door leaf wall shrinkage pool place, makes pinion 4.4 that the trend of downward motion always be arranged.

Gear wheel 11: be installed on the handle 5, can rotate with handle 5 and (see Fig. 1, Fig. 3).

Ratchet mechanism 9: be installed in the door leaf 1, there is round boss ratchet 9.1 lower ends, and boss is stuck in the groove on the door leaf wall, can only rotate along himself center.

The structure of ratchet mechanism 9 is seen Fig. 4, Fig. 5; Have square opening in the middle of the ratchet 9 and match, make pinion 4.4 and the ratchet 9.1 can be, but can not relatively rotate in axial relative slip with square shaft 4.1; Reseting shrapnel 9.3 behind the preload makes ratchet 9.2 and ratchet 9.1 realize one way engagement, and pinion 4.1 is realized unidirectional rotation; (annotate: about two groups of vertical center lines of the relative door leaf of unidirectional anti-reverse mechanism be symmetrical distribution, two groups of ratchet mechanism rotation directions are opposite).

Transmission process of the present utility model is described below:

When door leaf was in closed condition: hinge 2 compressed doorframe 8 (see figure 2)s under back-moving spring 2.3 effects; Sliding axle 3 presses down and fits leaf 2 in the pressure effect of compression spring 7, because the angle of wedge is very little, causes the outside thrust of wedge shape square hole on 3 pairs of hinges of sliding axle 2.6 very big, and hinge arc 2.2 is cooperated with door leaf closely; Doorframe 8 props up the end face of square shaft 4.1, makes pinion 4.4 be in state shown in Figure 3, and the gear wheel 11 on pinion 4.4 and the handle 5 does not mesh, and both are in released state.

When door leaf when open in the left side: rotate counterclockwise left side handle 5 as shown in Figure 1, effect lower link 6 drive sliding axles 3 compressing compression springs 7 at trundle 5.3 move to the right, thereby the wedge shape square hole 2.6 on sliding axle voussoir 3.1 and the hinge 2 is broken away from, door leaf 1 left side and doorframe 8 break away from, door leaf 1 rotates along right side hinge rotating shaft, and promptly door leaf 1 is finished unlatching from the left side.

Because door leaf 1 is opened defensive position and no longer handle 5 is applied twisting resistance, the trend of clockwise motion is arranged at the effect lower handle 5 of compression spring 7 at this moment, pinion 4.4 can only unidirectionally turn clockwise under the effect of ratchet rotating mechanism; When open in door leaf 1 left side, doorframe 8 disengages gradually with pinion 4.4, pinion 4.4 is in the effect lower edge of cylinder-shaped compression spring 4.3 glides downward, square shaft 4.1 stretches out door leaf 1 end face by the through hole on the door leaf 1, pinion 4.1 contacts with gear wheel 11 on the handle 5, realize engagement, thereby handle 5 can not be along turning clockwise, compression spring 7 is in impaction state, realizes one-way locking.

When closing the left side door leaf: the lower surface of doorframe 8 compressing square shafts 4.1, pinion 4.4 is slided vertically, thereby pinion 4.4 and gear wheel 11 disengagings on the handle 5 are meshed, realize release; After the release, compress the wedge shape square hole 2.6 on the hinge 2 on the left of the door leaf at the pressure effect downslide moving axis 3 that compresses spring 7, handle 5 dextrorotations go to position shown in Figure 1.
