Detailed Description

Example (b):

referring to figures 1-3 of the drawings,

the double-layer carton with the shock absorption function provided by the embodiment comprises a carton 1, a cover plate 101 and a clamping assembly;

both sides of the top of the carton 1 are provided with cover plates 101, the carton 1 comprises an outer layer 102 and an inner layer 103, the inner layer 103 is attached to the inner wall of the outer layer 102, and a placing plate 3 is arranged inside the carton 1;

the inside centre gripping subassembly that is provided with of carton 1 for carry out the centre gripping to the article of putting into carton 1.

Further, the clamping assembly comprises a clamping plate 2, buffer springs 201 and a pull rod 202, the two clamping plates 2 are arranged in the carton 1, the two buffer springs 201 are arranged between one side of the clamping plate 2 and the inner wall of the inner layer 103, the two sides of the carton 1 are both provided with slots, the pull rod 202 is connected in the slots in a sliding manner, one end of the pull rod 202 penetrates through the slots to be connected with the clamping plates 2, the other end of the pull rod 202 penetrates through the slots to protrude out of one side of the carton 1, when the device is used, the pull rods 202 which grasp the two sides of the paper box 1 apply force to the two sides respectively, so that the pull rods 202 drive the clamping plates 2 to move towards the slotting direction and compress the buffer springs 201, then the articles to be placed are placed on the top of the placing plate 3 in the carton 1 and between the two clamping plates 2, at this time, the force is not applied to the pull rod 202, the clamping plates 2 move towards the object direction through the elasticity of the buffer springs 201 until one side of the clamping plates 2 is attached to the object to clamp the object between the two clamping plates 2.

The clamping plates 2 are made of nitrile rubber materials, and the nitrile rubber materials have good elasticity, so that when the clamping plates 2 clamp and limit articles on the tops of the placing plates 3, the articles can be prevented from being clamped and damaged by the clamping plates 2;

for the material for making the splint 2, a silica gel material with better elasticity should be selected, and then a nitrile rubber material is selected, but the silica gel material has poor resilience, so that the silica gel material is easy to deform after being used for a long time, the clamping is unstable, the resilience of the nitrile rubber material is good, and the elasticity of the nitrile rubber material is enough for the splint 2.

Further, place 3 both sides of board and all be provided with slider 301, spout 302 has all been seted up to inlayer 103 both sides inner wall, slider 301 and spout 302 sliding connection, when carton 1 is in the transportation, carton 1 may receive vibrations, make article in the carton 1 to place board 3 and produce a decurrent power, place board 3 this moment and slide downwards through slider 301 and the cooperation of spout 302, make bracing piece 501 drive movable block 502 to the removal of dead lever 401 both ends, and compress spring 6, reaction force when compressing through spring 6 offsets the effort at movable block 502 to dead lever 401 both ends, thereby reach the effect of shock attenuation buffering.

Further, inner layer 103 inner wall bottom is provided with two fixed plates 4, is connected with dead lever 401 between two fixed plates 4, makes movable block 502 can the parallel slip through being provided with dead lever 401, and can not squint to guarantee the shock attenuation buffering effect.

Further, place 3 bottom both sides of board and all be provided with pivot one 5, 5 one sides of pivot are connected with bracing piece 501, dead lever 401 surface is provided with two movable blocks 502, the movable block 502 top is provided with pivot two 503, two 503 one sides of pivot are connected with bracing piece 501, the through-hole has been seted up to movable block 502 one side, movable block 502 passes through the through-hole and is connected with dead lever 401 sliding, make the support angle that can adjust bracing piece 501 through pivot one 5 and two 503 pivots, thereby guarantee the sliding effect of movable block 502.

Further, be provided with spring 6 between activity piece 502 one side and the fixed plate 4, activity piece 502 bottom is connected with stopper 601, and two spacing grooves 602 have been seted up to inlayer 103 inner wall bottom, and stopper 601 and spacing groove 602 sliding connection provide reaction force through spring 6 to activity piece 502 when sliding to slow down the sliding speed of activity piece 502, and make and place board 3 and obtain the buffering effect.

When the carton is used, the pull rods 202 on the two sides of the carton 1 are grasped to apply force to the two sides respectively, so that the pull rods 202 drive the clamping plates 2 to move towards the slotting direction, the buffer springs 201 are compressed, then an article to be placed is placed on the top of the placing plate 3 in the carton 1 and is positioned between the two clamping plates 2, at the moment, the pull rods 202 are not applied with force any more, the clamping plates 2 move towards the article direction through the elasticity of the buffer springs 201 until one sides of the clamping plates 2 are attached to the article to clamp the article between the two clamping plates 2, so that the article in the carton 1 jumps to cause damage when the carton 1 is transported, then the cover plates 101 are rotated until the top of the carton 1 is attached, then the two cover plates 101 are bonded through the external adhesive tapes, when the carton 1 is transported, the article in the carton may be vibrated to generate a downward force on the placing plate 3, at this time, the placing plate 3 slides downwards through the matching of the sliding block 301 and the sliding groove 302, so that the supporting rod 501 adjusts the supporting angle through the first rotating shaft 5 and the second rotating shaft 503, and drives the movable block 502 to move towards the two ends of the fixed rod 401 through the through hole, and compresses the spring 6, the reaction force generated when the spring 6 is compressed counteracts the action force of the movable block 502 towards the two ends of the fixed rod 401, thereby achieving the effect of shock absorption and buffering, and when the carton 1 is not vibrated, the movable block 502 is pushed to move towards the middle of the fixed rod 401 according to the elastic force of the spring 6, so that the movable block 502 returns the supporting rod 501 to the original position through the second rotating shaft 503 and the first rotating shaft 5 to support the placing plate 3, the device clamps and limits the article on the top of the placing plate 3 through the two clamping plates 2, thereby preventing the article on the top of the placing plate 3 from jumping in transportation, and the spring 6 provides the reaction force to buffer the placing plate 3, thereby ensuring that the article on top of the placing plate 3 obtains a cushioning effect so as to avoid damage to the article.
