As shown in fig. 2, the locking mechanism is a snap-fit locking mechanism; the buckling type locking mechanism comprises a through hole 9 formed in the middle of the bearing block 5; a locking rod 10 is connected in the through hole 9 in a vertical sliding manner; the upper end of the locking rod 10 is fixed with the lower side of the middle part of the supporting shaft 1; the lower part of the front side of the locking rod 10 is uniformly distributed with clamping grooves 11 from top to bottom; a limiting elastic sheet 12 is fixed at the front end of the through hole 9; the limiting elastic sheet 12 is matched with the clamping groove 11 in a buckling manner; the locking lever 10 is provided with an unlocking mechanism.

As shown in fig. 3 to 4, the unlocking mechanism includes a groove 13 opened at a lower portion of a front side of the locking lever 10; the groove 13 penetrates through the middle part of the clamping groove 11; a push bar 14 is connected in the groove 13 in a sliding manner along the front-back direction; the rear end of the push bar 14 is connected with the rear end of the groove 13 through a tension spring 15; a wedge-shaped stop 16 is fixed at the rear end of the push bar 14; the lower end of the rear side of the locking rod 10 is vertically provided with a slot 17; the slot 17 is internally and slidably connected with an inserting rod 18; the slot 17 is connected with the groove 13 through a through groove 19; a wedge-shaped push block 21 is fixed on the front side of the inserted link 18 through an extension block 20; the extension block 20 passes through the through groove 19 and extends into the groove 13; the wedge-shaped push block 21 is correspondingly matched with the wedge-shaped stop block 16.

Among this technical scheme, at first expand the regulation and the locking effect of fagging 2 scope of opening through locking mechanical system to two, make its width that adapts to space between goods and the packing box, make two expand fagging 2 can contact and support with packing box inner wall and goods lateral wall respectively, can inject the goods in the packing box (can correspond according to the quantity in space and set up a plurality of shock pads) through this process. The buffer sleeve 6 can be made of rubber, and the production process can adopt a rubber coating or gum dipping mode.

Traditional shock pad is not enough because the intensity of self, compressive capacity is not strong, and produced powerful pressure during heavy goods vibrations probably surpasss traditional shock pad's resistance to compression limit, leads to the shock pad to be unable the recovering after shriveled, and more serious probably is crushed even, in case take place this kind of condition, just means the packing support effect of shock pad this moment and is destroyed, can't have the vibration range of effect restriction heavy goods again to make shock attenuation effect greatly reduced.

Different from the traditional shockproof pad, the expanding plate 2 and the supporting spring plate 3 in the technical scheme are made of high-carbon steel, and the high-carbon steel has extremely high strength, hardness and elastic limit. The extremely high strength and hardness of the heavy goods determine that even if the heavy goods generate strong pressure during vibration, the high-carbon steel expanded support plate 2 and the support elastic sheet 3 can bear easily and cannot be damaged; the extremely high elastic limit ensures that even if strong vibration pressure is applied, the expanded supporting plate 2 and the supporting elastic sheet 3 can still restore to the original state after being deformed, and the problem that the supporting function of heavy goods is damaged because the expanded supporting plate cannot restore after being deformed by pressure can not be caused; in addition, compare the elasticity modulus of high carbon steel bigger with the shock pad of traditional material, when receiving the same pressure promptly, the deformation degree is less, compares traditional shock pad promptly, uses the shock pad of this technical scheme can effectively reduce the vibration range of heavy goods to the reinforcing is to the protection effect of heavy goods (the vibration range is big more, the probability that the goods damaged is high more).

Example 1:

in this embodiment, locking mechanical system is screw thread formula locking mechanical system, when adjusting two expansion fagging 2 and opening the range, only need rotate rocker 8 and drive screw rod 7 rotatory, can be through the effect of screw rod 7 with 5 threaded connection of carrier block, change the deformation degree that supports shell fragment 3, change two expansion fagging 2's the range of opening then, stop to screw rod 7's rotation back, two expansion fagging 2 open the range also just can be locked.

Example 2:

the difference between this example and example 1 is: the locking mechanism adopts a buckling type locking mechanism and is provided with an unlocking mechanism. When the opening range of the two expansion supporting plates 2 is adjusted in the embodiment, the unlocking mechanism is firstly utilized to release the fastening state of the limiting elastic sheet 12 and the clamping groove 11, at this time, the opening range of the two expansion supporting plates 2 can be freely adjusted, then, the opening range of the two expansion supporting plates 2 is adjusted in place by utilizing an external tool such as a vice, and then, the effect of the unlocking mechanism is released, so that the limiting elastic sheet 12 is fastened with the corresponding clamping groove 11, and the opening range of the two expansion supporting plates 2 is locked.

The unlocking mechanism in the initial state is shown in fig. 3, at this time, the tension spring 15 is in an unstretched state, and the push bar 14 does not reach the card slot 11; when the buckling state of the limiting elastic sheet 12 and the clamping groove 11 needs to be released, the inserting rod 18 slides in the inserting rod 18, the wedge-shaped pushing block 21 pushes the wedge-shaped stop block 16, the tension spring 15 is stretched, the pushing strip 14 can move forwards along the groove 13, as shown in fig. 4, the pushing strip 14 reaches the front end of the groove 13 at the moment, the limiting elastic sheet 12 is pushed out from the clamping groove 11, the locking relation between the locking rod 10 and the bearing block 5 is released, and the opening amplitude of the two expanding plates 2 can be adjusted; after the adjustment is finished, the external force on the inserting rod 18 is removed, the pushing strip 14 can be pulled back through the elasticity of the tension spring 15, the unlocking mechanism can return to the initial state again, the limiting elastic sheet 12 can be buckled into the corresponding clamping groove 11 again through the elasticity of the limiting elastic sheet, and the opening range of the two expansion supporting plates 2 can be locked.

In this embodiment, the card slot 11 may adopt a saw-tooth shape as shown in fig. 3-4, and the card slot 11 adopting this shape has the advantages that: after the limiting elastic sheet 12 is fastened with the clamping groove 11, only the limiting elastic sheet 12 is limited to slide downwards along the locking rod 10, but the limiting elastic sheet 12 is not limited to slide upwards along the locking rod 10, namely when the locking mechanism does not work, the limiting elastic sheet 12 can automatically slide upwards along the locking rod 10 along the inclined surface of the clamping groove 11 through the elastic action of the supporting elastic sheet 3 during deformation recovery, and the opening amplitude of the two expansion plates 2 can automatically recover to the maximum.

The aforesaid characteristic is used in this technical scheme for when placing the antivrbration pad, only need expand fagging 2 earlier and open the range pressure little, put into in the space between packing box and the goods, later two expand fagging 2 can expand the range of supporting the goods by oneself, because this kind of expansion process is irreversible, so need not to adjust carelessly, can make the antivrbration pad provide abundant support and injecing to the goods, it is more convenient, more reliable when installing the antivrbration pad in the space.
