In the embodiment of the present invention, the hinge structure 41 may be a hinge, the supporting plate 40 may be divided into a main supporting plate 40a and a plurality of auxiliary supporting plates 40b, the main supporting plate 40a is rotatably connected to the groove wall of the accommodating groove 30 through a rotating shaft 40c, and each auxiliary supporting plate 40b is hinged to each other through a hinge.
The utility model discloses in the embodiment, each backup pad 40 all includes plate body 400 and a plurality of fixed connection in the antislip strip 401 on each plate body 400 terminal surface, each antislip strip 401 all include two fixed connection in on the plate body 400 and interconnect and be obtuse antislip strip components of a whole that can function independently 4010.
In the embodiment of the present invention, the sharp corners C of the anti-slip strips 4010 face the bottom rod 20.
By adopting the technical scheme: the utility model adopts the support module to form an inclined plane for the fork truck to move, when the airtight door is closed, the support module is contracted in the holding tank, which can not only ensure the smooth movement of the fork truck, but also can not influence the sealing effect of the airtight door;
in more detail:
referring to fig. 2-4, the principle of the present embodiment is:
when the door is closed, the supporting modules are all positioned in the accommodating groove, referring to fig. 2, the length of the supporting plate can be smaller than the depth of the accommodating groove, the auxiliary supporting plates are folded through hinges between the adjacent auxiliary supporting plates, and finally the rotating shaft is rotated, so that the main supporting plate and the auxiliary supporting plates are folded and are contracted in the accommodating groove;
it should be noted that: in order to avoid the fork truck in-process of traveling to skid, set up the antislip strip in each backup pad for improve the frictional force of fork truck and backup pad, not only so, still with each antislip strip closed angle towards bottom plate, its purpose: because the orientation of antislip strip closed angle is all signaling the upslope, and should set up the relatively straight line shape antislip strip, its fork truck upslope of being convenient for to reach convenient and laborsaving purpose.
Example 2 is different from example 1 in that
As shown in fig. 6-8, in the embodiment of the present invention, the base 1 is provided with a plurality of grooves 50 corresponding to the holding grooves 30 one by one and extending to two sides of the base 1, a cylinder cavity 51 recessed into the bottom of each groove 50 near the bottom of the bottom rod 20, a driving cylinder 52 installed in the cylinder cavity 51, and a damping plate 53 hinged to the groove wall of the groove 50 far from the bottom rod 20 and having the other end lifting and lowering through the driving cylinder 52 and contacting with each supporting plate 40.
In the embodiment of the present invention, the damping plate 53 may be rotatably connected to the groove wall of the groove 50 through a hinge shaft 53 a.
The utility model discloses in the embodiment, be equipped with the blind hole 530 that a plurality of rows of intervals set up on the shock attenuation board 53, the bottom of the hole of each blind hole 530 all exposes the snubber block 532 of blind hole 530 through a plurality of parts of compression spring 531 fixedly connected with, and the equal fixedly connected with rubber layer 533 of a side end face that compression spring 531 was kept away from to each snubber block 532.
In the embodiment of the present invention, the adjacent blind holes 530 are disposed in a staggered manner.
In the embodiment of the present invention, the bottom of each blind hole 530 is set to be a slant plane 5300 corresponding to the slant plane 4000.
By adopting the technical scheme: because the article weight upper limit and the lower limit that exist in the warehouse are all higher, when some heavier article of weight consigns via fork truck, very easily damage the backup pad, consequently, this embodiment has adopted the shock attenuation board for the auxiliary stay board, its principle is:
referring to fig. 6, when the supporting plates are scattered and form an inclined plane, the driving cylinder may drive the damping plate in the groove to ascend and descend, that is: the damping plate is driven to lift at one end close to the bottom rod, and the damping plate is in contact with the supporting plate, so that the supporting upper limit of the supporting plate is improved, the supporting plate is prevented from being damaged, and when the damping plate is not used, the damping plate is driven to fall through the driving air cylinder, and the normal use of the airtight door is further ensured;
it should be noted that: in order to further improve the damping effect of the embodiment, the damping plate is provided with blind holes, and damping blocks connected through compression springs are arranged in the blind holes, so that the damping effect of the support plate can be provided through the matching of the damping blocks and the compression springs (the damping blocks can be in contact with the support plate), the damage of the support plate is avoided, and furthermore, in order to further improve the damping effect of the damping blocks, the blind holes are distributed in a staggered manner, so that the damping blocks can assist the support plate at different positions, in addition, the damping blocks are also provided with rubber layers for improving the flexibility of the stress surface of the damping blocks and reducing the abrasion loss between the damping blocks and the support plate; the hole bottom of blind hole establishes to the laminating degree that the inclined plane can improve "stress surface" and the backup pad of snubber block, promptly: the blind holes on the two sides of the bottom rod respectively correspond to the inclined planes on the two sides of the bottom rod.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
