Description
Technical Field
The invention relates to the logistics turnover industry, in particular to a box body device for bearing, loading, unloading and transporting turnover of nonmetal raw material blocks such as rubber, chemical fiber and the like.
Background
The folding box or the logistics box is generally used for bearing, loading, unloading and transporting non-metal material blocks such as rubber, chemical fiber and the like, and generally comprises a chassis, a front door, a rear door, a left door and a right door.
Among the prior art, the front and back door is when installing with the chassis, and every front and back door lower extreme all needs two bolts to paint the binder after, and manual operation screws up the bolt, because of the front and back door is heavier, because of the bolt setting is in the bottom simultaneously, needs two at least people to accomplish, wastes time and energy, and during the maintenance, after more needing the binder that the heating is baked and is solidified, reverse operation, one screws down the bolt, the front and back door can be taken off.
In the prior art, the left door and the right door are connected with the chassis through the fork shafts and the bolts, due to the structural size, the diameters of the fork shafts are very small, even though a high-strength material is adopted, the opening and closing actions are operated all year round, the deformation is serious in the practical situation, the service life is influenced, and the left door panel and the right door panel need to be subjected to pressure forming at the joint of the fork shafts, so that the protective effect of preventing rubber scraps from entering is achieved, but the pressure forming processing process is complex, and labor and time are wasted.
In the prior art, the chassis adopts a Z-shaped profiled strip with the thickness of 3.0mm in four dimensions, although a high-strength material is adopted, the structural size is larger and easy to deform, so that a plurality of vertical pipes are adopted for reinforcement, the design is rigid and complicated, the upper part of the Z shape is still a single-piece non-reinforced support, the large left door and the large right door are blocked by the high-strength plate with the thickness of 3mm, and the slightly obvious force is insufficient.
Among the prior art, this kind of metal box no matter is folding back pile, still carries the thing back pile, because the pile spare is too little, during operating personnel operates, the degree of difficulty is fairly big. Due to the limitation of the inner and outer sizes of the box body, the size of the stacking piece cannot be increased by the stacking piece design, the stacking piece design becomes a big problem in the industry, and the feedback and modification willingness of a user is strong.
In the prior art, the operation is extremely complicated to accomplish the erection of the folding box. Under fold condition, when the artificial upright state of lifting of door by fold condition around with, the front and back door is not vertical location and is standing up, because of its location structure's reason, need lean out certain angle, treat to open the upright back of left and right sides door, need hold in the palm left and right sides door on one hand, the door rotates inwards around dragging with the other hand, hold in the palm that the door will open the rotation padlock on the left and right sides door about simultaneously, the front and back door closes behind the left and right sides door, loosen and adjust the hand of controlling the door padlock, the operation of one side can be ended to the buckleing rear. Then, when the lock on the other side of the left door and the right door and the front door and the rear door on the other side are locked, the other side of the left door and the right door needs to be pushed inwards for a distance because the left door and the right door are dislocated, the lock cannot be released by forcibly opening the lock, the other front door and the rear door are pulled inwards by the other hand to be closed, and the lock can be locked after the lock is aligned.
When the left door and the right door on the other side are locked, the locking is doubled, and at the moment, the two front doors and the two rear doors are locked with the first left door and the first right door to be upright, the latches at the two ends need to be forced to be turned over and opened, and then the latches are aligned and fastened. Since it is substantially impossible to operate two locks simultaneously, only one lock can be operated, but this is the problem: when the second left and right doors are turned to be close to the upright state, a front and back door with one hand and a left and right door with the other hand are needed; when a second lock of a second left door and a second right door is locked, the lock is in a 'no leg' state, the left door and the right door need to be pushed inwards by one hand, the lock buckle needs to be lifted by the other hand, the hand which needs to be lifted needs to be exchanged at this time, then the front door and the rear door are righted by the other hand, and the lock is locked after alignment. The visualization process is very complex.

The advantages of all the above technical solutions over the prior art are:
1. the folding is convenient:
for the left door and the right door, the left door and the right door can be laid down in the box by rotating only by pulling the left door lock and the right door lock inwards. The pin shaft is designed for special function, penetrates into two coaxial sleeves of the left door, the right door and the chassis, and is characterized in that two groups of bosses in the vertical direction are punched at the position where the pin shaft penetrates into one sleeve, and two bosses in each group are formed. When the anti-blocking sleeve is installed, the pin shaft is embedded from one end, the front end of the pin shaft can smoothly enter the sleeve without a boss, and the rear end of the pin shaft is in interference fit with the sleeve when reaching the boss, namely, one sleeve is locally deformed and expanded after being extruded by the boss, so that the anti-blocking effect is achieved. The hinge has the characteristics of ingenious structure, simple installation, firm connection, convenient disassembly and convenient maintenance.
For the front and rear doors, the front and rear doors can be laid down in the box by slightly lifting the front and rear doors. Generally, the fitting bodies at the bottoms of the front and rear doors are not easy to be separated from the fixing grooves, so that the front and rear doors can be prevented from being separated accidentally. But through rotating the chimera to specific angle, can also with front and back door separation chassis to can maintain front and back door. In a word, the front and back door can be erect, can fall down, can abduct and stand to one side, more can take off from the chassis, convenient loading and unloading and maintenance.
2. The tool to lock is fixed convenient effective:

The top edges of the front door leaf 133, the rear door leaf, the left door leaf 231 and the right door leaf are all located on the same horizontal plane; the tops of the rear left upright column 411, the rear right upright column 412, the front left upright column 111 and the front right upright column 112 are all higher than the horizontal plane, and the upper surface of the tops of the front left upright column, the front right upright column 111 and the front right upright column 112 is provided with a first stacking groove 61; a stacking positioning block 6 is further fixed below each fixing groove on the chassis 5; a second stacking groove 62 is formed in the bottom surface of each stacking positioning block 6, and a stacking protrusion block 63 which is aligned with the first stacking groove 61 in the vertical direction is arranged at each second stacking groove 62; the top of each fixing groove is also provided with a fixing groove stacking projection 64 vertically aligned with the second stacking groove 62.
The two fixing grooves (the rear left fixing groove 53 and the rear right fixing groove 54) positioned at the rear part are in mirror symmetry, the two fixing grooves (the front left fixing groove 51 and the front right fixing groove 52) positioned at the front part are also in mirror symmetry, and mirror symmetry planes are vertical planes which face the left and right directions and penetrate through the center of the chassis 5;
the two fixing grooves (the rear left fixing groove 53 and the front left fixing groove 51) positioned on the left side are in mirror symmetry, the two fixing grooves (the rear right fixing groove 54 and the front right fixing groove 52) positioned on the right side are also in mirror symmetry, and mirror symmetry planes are vertical planes which face the front and back direction and penetrate through the center of the chassis 5;
the chimeras (front left chimera 151, front right chimera 152, rear left chimera 451, rear right chimera 452) corresponding to each fixing groove all satisfy the completely same mirror image relationship. In addition, the left door 2 and the right door 3 are arranged in a mirror symmetry mode, and a symmetry plane is a vertical plane which faces the front-back direction and penetrates through the center of the chassis 5;
we illustrate the connection and function of the left fixation groove 51 and the left chimera 151, and the connection of the other three groups of fixation grooves and chimeras is completely determined by mirror image:
as shown in fig. 27, during installation, the front left fitting body 151 needs to be rotated by an angle (the angle can be 45 °, that is, the angle between the front left fitting body 151 and the horizontal plane is 45 °) so that an inclined plane of the front left bottom boss 1512 cut off is located in the vertical direction, and therefore, when the horizontal width of the inclined plane and the top width of the front left sliding chute 515 are the same length value of d1, the front left bottom boss 1512 can be inserted into the front left sliding chute 515. After the insertion, the front left bottom boss 1512 enters the middle of the front left sliding groove 515 so as to rotate the front left insertion body 151, and at this time, the front left insertion body 151 can be rotated to the vertical direction and continuously moved downward, so that the front left bottom boss 1512 can be inserted into the bottom of the front left sliding groove 515, the front left top boss 1511 can be inserted into the top of the front left sliding groove 515, and at this time, the front left insertion body 151 is completely fixed to the front left sliding groove 515, as shown in fig. 28 to 29.
When the front left fitting body 151 and the front left upright 111 connected to the upper portion thereof need to be rotated to a lying state (at this time, the front door 1 can be laid down), the front left fitting body 151 can be lifted to make the front left top boss 1511 separate from the front left sliding groove 515, and then the front left fitting body 151 is rotated to be horizontal, as shown in fig. 30.
Generally, for example, in the vertical state, as shown in fig. 31, the front left fitting body 151 is not easily detached from the front left fixing groove 51, and can be detached only by manually adjusting the angle until the inclined plane of the front left bottom boss 1512 is in the vertical direction, which is determined by the relationship of d1 < d4 < d5 < d3 < d2, so that the front left fitting body 151 can be prevented from being accidentally detached from the front left fixing groove 51. With such a connection, inward folding of the front door 1 can be achieved. When the front door 1 needs to be replaced and the front door is worn or has a fault, the front left mosaic body 151 can be separated from the front left fixing groove 51, so that the parts can be maintained or replaced independently.
The installation and folding process of the front door 1 is described above, and the installation and folding process of the rear door 4 is completely determined by symmetry.
For the whole folding box (logistics box), when the folding box needs to be folded, the lockset on the left door 2 is pulled inwards, so that the left door 2 can be released from the rear left upright column 411 and the front left upright column 111, and the bottom of the left door is hinged to the chassis 5, so that the left door can be laid inside the folding box through rotation; in exactly the same way, the right door 3 can be laid down inside the folding box; then, the mosaic bodies of the front door 1 and the rear door 4 can be folded in the folding box after being lifted; thus, the whole folding box can be folded.
Stacking of a plurality of folded folding boxes is possible, and specifically, as shown in fig. 32, the stacking projection 63 at the bottom of the folding box located above is fitted into the fixing groove located below, and due to the cooperation of the second stacking groove 62 and the fixing groove stacking projection 64, the stacking can be tightly achieved. Four angles all pile up respectively according to above-mentioned mode can. In addition, the stacking can be repeated to form multi-layer stacking, so that the storage space of the folding box can be greatly saved;
when the folding box is needed to be used for storing articles, the front door 1 and the rear door 4 are lifted firstly and then are installed in the fixing grooves, then the left door 2 is lifted, the left door 2 is limited by the left door limiting plate 56, the rear left limiting plate 461 and the front left limiting plate 161 so as not to be overturned, the rear left protruding block 261 and the front left protruding block 262 are respectively embedded into the rear left limiting opening and the front left limiting opening 171, and meanwhile, due to the arrangement of the sliding inclined planes at the end parts of the left rear lock upper locking rod 251 and the left front lock upper locking rod 252, the lock can retreat through the contact of the sliding inclined planes with the rear left upright column 411 and the front left upright column 111 in the moving process so as to be embedded into the openings arranged on the upright columns. The configuration of the sliding ramp is shown in fig. 26. The lifting and fixing process of the right door 3 is exactly the same as that of the left door 2.
When storing articles, the front door leaf 133 can be detached separately to facilitate the insertion or removal of the objects, as follows: the front door leaf 133 can be separated from the front left upright post 111 and the front right upright post 112 by pulling the lockset of the front door 1 inwards, and at the moment, the front door leaf 133 is lifted, so that the front door leaf fixing strip 18 can be separated from the front upper embedded strip 19, and the front door leaf 133 is detached; in the above process, due to the arrangement of the left and right stoppers 131 and 132, the front door leaf 133 will not fall into the folding box, so as to prevent the inner surfaces of the left and right doors 2 and 3 from being scratched by the protruding front left and right lock locking rods 1413 and 1423 pushed by the spring. When the front door 133 is installed, the process may be performed in the reverse direction. In the state of storing articles in the folding boxes, stacking can be achieved, specifically, one folding box is placed above the other folding box, the stacking convex block 63 of the upper folding box is embedded into the first stacking groove 61 of the lower folding box, and stacking can be achieved by embedding all four corners, as shown in fig. 33.
Fig. 34 shows a schematic connection diagram of the first left connecting sleeve 28 and the second left connecting sleeve 55, during installation, the left pin is forcibly hammered into the two sleeves from left to right, the outer diameter of the left pin is slightly smaller than the inner diameters of the first left connecting sleeve 28 and the second left connecting sleeve 55, but a left pin boss is arranged on one side, for example, the left side in the drawing, so that the right side of the left pin can smoothly enter the second left connecting sleeve 55 through the first left connecting sleeve 28, and the two left pin bosses can be embedded into the first left connecting sleeve 28 and fixed by forcibly hammering the left pin, so that the hinging is realized. The connection of the first left adapter sleeve to the second left adapter sleeve is exactly the same as described above.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
