Detailed description of the invention
With reference to Fig. 1, Fig. 4, this utility model provides a kind of collapsible concrete test die, including base plate and side plate, its latus inframedium has four pieces, it is followed successively by the first side plate the 1, second side plate the 2, the 3rd side plate 3 and the 4th side plate 4 in the direction of the clock, side plate all with base plate chain connection, the first side plate 1 is provided with first determines mechanism for what fix the second side plate 2, and the 3rd side plate 3 is provided with the second locking mechanism for fixing the 4th side plate 4. The structure of the two locking mechanism is the same, and the first locking mechanism by one of them illustrates:
First locking mechanism includes the first card body 11 and is located on the second side plate 2 and first draw-in groove 21 suitable with described first card body 11, described first side plate 1 is provided with, near the one side of the second side plate 2, the first through hole 12 placing the first card body 11, the aperture place of the first through hole 12 is provided with the first limited block 121, the first spring 15 it is provided with between the other end and the first card body 11, first card body 11 is released the first through hole 12 by the first spring 15 in its natural state, thus, when holding up the first side plate 1 and the second side plate 2, first card body 11 can be retracted in the first through hole 12 owing to touching the second side under the effect of the first spring 15, until two blocks of side plates are completely in vertical state, now the first card body 11 is relative with the first draw-in groove 21 position, first card body 11 sticks into again in the first draw-in groove 21 under the action of the spring, owing to the first card body 11 closely engages with the first draw-in groove 21, will not rock, cement casting is entered after die trial without by spreading, unless the first card body 11 is pressed back in the first through hole 12, 3rd side plate 3 and the 4th side plate 4 in like manner pin.
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 5, this collapsible concrete test die is folding, smooth to be folded, then need two blocks of side plates of correspondence to base plate folded inside, other two blocks of side plates fold to plate outer side, then side plate maximum demand rotates 270 degree, and general articulated structure is extremely difficult to this requirement, is then provided with structure with double rotating shafts. And the height of this die trial not can exceed that the half of baseplate width, the phenomenon overlapped otherwise can be produced; And because to allow connector play a role, namely two boards folding after distance be less than the length namely height of connector, so this is highly greater than 1/3rd of floor length. About this structure with double rotating shafts, being provided with mean for, at bottom panel side, the first axis hole that the first rotating shaft 51 is inserted, the first rotating shaft 51 two ends are provided with the connection sheet 5 with jack, and side plate is provided with second rotating shaft 52 suitable with jack. When this die trial installed by needs, floor level being placed, side plate needs vertical with base plate, then first by the first rotating shaft 51, connection sheet 5 is gone to vertical direction, then also by the second rotating shaft 52, side plate is gone to vertical direction.
When folding, directly two blocks of side plates folded inward are continued laminating inside 90-degree rotation and base plate, the side plate of other two pieces of folded outwards then needs first around the first rotating shaft 51, connection sheet 5 to be revolved turnback i.e. vertical direction down, is rotated further by side plate until fitting with plate outer side. Side plate after folding easily rocks, and is fixed by plate so needing to arrange locking mechanism. Assuming that the first side plate 1 and the 3rd side plate 3 are to base plate folded inside, the second side plate 2 and the 4th side plate 4 fold to plate outer side, then arrange the 3rd locking mechanism between the first side plate 1 and the 3rd side plate 3 and prevent side plate from rocking; It is also provided with for preventing the 4th locking mechanism rocked between the second side plate 2 and the 4th side plate 4. Owing to the structure of the two locking mechanism is the same with usage, the 3rd locking mechanism by one of them illustrates:
3rd locking mechanism includes one end and sets first screw 31 corresponding with head rod 14 of threaded head rod 14 and the upper surface being arranged on the 3rd side plate 3, the upper surface of the first side plate 1 is provided with the third through-hole 13 for placing head rod 14, the aperture of third through-hole 13 is provided with the 3rd limited block 131, head rod 14 is being provided with the first conflict block away from first screw thread 141 one end, so head rod 14 that is just prevented from skids off, the length of head rod 14 is more than the degree of depth of third through-hole 13, namely under naturalness, head rod 14 stretches out aperture, such design is not only without influence on the molding of test specimen but also be arranged in die trial by this fixture, it is not easy to lose. after so, after the first side plate 1 and the 3rd side plate 3 fold into same plane, with hands, the first connector being pulled out through hole, until encountering the first screw 31, then it is fixed with the first screw 31 and is connected by rotation head rod 14, in like manner connect the second side plate 2 and the 4th side plate 4. after so, whole die trial builds up three layers altogether, reduces parking space, without injuring people, equipment safety in moving process by a crashing object because plate rocks.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model. It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
