Fig. 3 is the schematic diagram of locking system unlocking operation.

The specific embodiment

As shown in Figure 1, collapsible container, for example container comprises the pedestal 8 with rectangular flat structure, wherein

collapsible side plate

1,2,3,4 is connected in the edge of pedestal 8 through hinge component.When

side plate

1,2,3,4 is in the erection position,

side plate

1,2,3,4 through after the locking system stated combine to connect, and then remain on erectility.Alternatively, side plate 4 is provided with a wicket 5, between wicket 5 and the side plate 4 also can through after the locking system stated combine to connect, be in closed condition to keep wicket.

As shown in Figure 2, locking system is installed in the position of side plate 4 adjacent side plates 1, comprises a grip 9 and lock bolt 10.

Upside at Fig. 2 latus inframedium 4 is the outside, and downside is inboard, handle 9 from outside look sideways; The tabular of its body squarely is looked sideways before from Fig. 2, and its upper and lower side walls is leg-of-mutton tabular; Do not illustrate among the figure; But it is understandable that, see that the left side wall of handle is square tabular from the left side of Fig. 2.Therefore as shown in Figure 2, handle 9 is accommodated in the side plate 4, the occupying volume external space not.

Control arm 151 as shown in Figure 4, that lock bolt 10 has tongue 15 and stretches out from the both sides of tongue 15 has the direction recess 17 and the concave surface profile 12 of strip shape on each Control arm 151.Direction recess 17 on the corresponding Control arm 151 has protruding 16 on the two opposite side walls of the recess 40 of side plate 4.Concave surface profile 12 on the corresponding Control arm 151 respectively has protruding pin 11 on the upper and lower sidewall of handle 9.

As shown in Figures 2 and 3, but protruding pin 11 and concave surface profile 12 contact matching and can be carried out transmission forming sliding pair; Therefore handle 9 constitutes lever system with lock bolt 10; This handle 9 is with pivot 13 (as shown in Figure 4) and is the crank of fulcrum and is driving link, and output is rotated, and this lock bolt 10 is a driven member; Linear movement output, the distance of the force application part of handle 9 to this fulcrum is greater than the distance of said sliding pair to this fulcrum.

Continuation also has pivot 13 with reference to Fig. 4 on the upper and lower sidewall of handle 9, correspondingly, on the upper and lower sidewall of recess 40 pin-and-hole 20 is arranged.Pivot 13 is inserted in the pin-and-hole 20, thus handle 9 just with pivot 13 be axis relatively side plate 4 outwards overturn.Simultaneously with reference to Fig. 1, preferably, pivot 13 is perpendicular to pedestal 8.

As shown in Figures 2 and 3, the tongue 15 of lock bolt 9 extend in the groove 14 of side plate 1, and at this moment side plate 1,4th, each other the state of locking.Because handle 9 has pivot 13; When breaking handle 9 around axle 13 rotations off with the fingers and thumb, the protruding pin 11 on the handle 9 and the left end of the concave surface profile 12 on the lock bolt 10 contact and drive lock bolt 10 and be moved to the left, and make its tongue 15 break away from the groove 14 of side plates 1; Thereby remove the mutual locking of 1,4 of side plate.

As shown in Figure 3, when locking system was in released state, handle 9 was broken off with the fingers and thumb the angle (for example about 35 degree) of a setting; The confined planes 18 on the side plate 4 at this time; 19 contact for the face face with lateral surface, the left surface of handle 9, rely on mutually, and handle 9 can't outwards rotate again.Simultaneously with reference to Fig. 1, when people catch the inside folded side plate 4 of handle 9, handle 9 will bear the part side plate from gravity.And the rotating hinge 13 of the confined

planes

18,19 of side plate 4 and handle 9 has effectively been shared these from gravity, is unlikely to handle and damages easily.

Two convexities 16 on the side plate, when lock bolt 10 is inserted in the side plate 4 from the outside, direction recess on the lock bolt 17 is lucky has held protrudingly 16, and like this, lock bolt just can not deviate from from side plate 4 because of the reset force of gravity, general withdrawing power or lock bolt 10 self.

As shown in Figure 4, during assembling, lock bolt 10 at first is inserted into the side plate 4 from the side of side plate 3, and protruding 16 can not deviate from its qualification, are assembled to the side plate 4 from the front with handle 9 then, make rotating hinge 13 enter into the hole 20 of side plate; Anti-operation in tandem gets final product during dismounting.

Lock bolt 10 has spring, two elastomeric blades 21 for example, and it is used for resetting and making it remain on lock-out state of lock bolt 10 between the side and tongue 15 of side plate 4, and promptly tongue 15 is in the state that stretches out.When side plate 4 when folded state changes to running condition, when rotating to certain angle, the tongue 15 of lock bolt 10 will collide with side plate 1, make lock bolt to side plate 4 inner moving.The concave surface profile 12 of lock bolt 10 is microscler profiles, rotates so when it moves inward, can't drive handle 9.

As shown in Figure 3, the force application part of handle 9 (right side edge) has certain distance with respect to pivot 13 and protruding pin 11, and this is apart from having increased the arm of force, and the process of the handle 9 that therefore overturns can be known through lever principle, and is very laborsaving.
