Description

Technical Field

[0001] The utility model relates to the technical field of logistics and transportation, in particular to a packing wooden box for logistics and transportation. Background Art

[0002] With the highly developed logistics industry today, it is becoming more and more common to use packaging boxes to transport goods. Since squeezing and collision are inevitable during the transportation of goods, some precision instruments and fragile items need to be protected from shock during transportation. Traditional packaging boxes are usually filled with small particles of foam plastics for shock protection. Since the deformation of small particles of foam plastics is small, the shockproof effect is poor, and it is easy to cause foam to fly when taking out items. In addition, filling other shockproof materials in the packaging box is troublesome, occupies a large space, and is difficult to recycle.

[0003] For example, publication number CN218578538U discloses an earthquake-resistant packaging wooden box for logistics transportation, including a base, characterized in that: a first shock-absorbing component is provided on the top surface of the base, a protective partition is provided on the outside of the first shock-absorbing component, an outer box is installed above the first shock-absorbing component, a box cover is installed on the top of the outer box, an insulation layer is installed on the inner wall of the outer box, a fixed frame component is installed on one side of the insulation layer, an inner box is installed inside the fixed frame component, and a second shock-absorbing component is installed between the inner box and the insulation layer. The application has a simple structure and a low failure rate. It uses double protection of the inner box and the outer box to protect items from damage. By arranging a damping spring shock absorber between the inner box and the outer box and arranging the first shock-absorbing component at the bottom of the outer box, double shock absorption reduces the impact caused by left and right collisions during transportation, and also reduces the probability of transported items being damaged by impact during loading and unloading.

[0004] However, in the prior art, when conventional wooden boxes encounter bumpy roads during transportation, the objects will shake slightly with the bumps, and the positioning plates on both sides cannot adjust the degree of clamping on both sides of the objects in real time, resulting in friction between the objects and the positioning plates on bumpy roads, causing damage to the objects, thereby limiting the practicality of the device to a certain extent.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a packaging wooden box for logistics transportation, comprising a main body, an inner bottom wall of the main body is symmetrically fixedly connected with a pressure sensor, the outer side of the pressure sensor is fixedly connected with an airbag assembly, the airbag assembly comprises an air tank, the inner side of the pressure sensor is fixedly connected with a connecting sleeve, the connecting sleeve and the pressure sensor are fixedly connected via a contact block, a reset spring is fixedly connected to the side of the contact block away from the pressure sensor, one end of the reset spring is fixedly connected to a grinding block, the output end of the air tank is fixedly connected to a sealing sleeve via a U-shaped tube, and the sealing sleeve is fixedly connected to the inner side wall of the main body, the inner cavity of the sealing sleeve is movably connected with a movable rod, and one end of the movable rod is fixedly connected to a positioning plate.

[0007] As a preferred implementation, a top cover plate is fixedly connected to the upper surface of the main body, and a protective cover is symmetrically fixedly connected to the outer side wall of the main body.

[0009] As a preferred embodiment, the inner wall of the main body is fixedly connected to a placement plate via a shock-absorbing spring, and the lower surface of the placement plate is symmetrically fixedly connected to a trapezoidal block.

[0010] As a preferred implementation, a fixing block is symmetrically fixedly connected to one side of the inner bottom wall of the main body close to the pressure sensor, and the two fixing blocks are fixedly connected via a fixing rod.

[0011] As a preferred implementation, a second damping spring is fixedly connected to the inner side of the fixed block and the outer surface of the fixed rod, and a movable block is slidably connected to the middle part of the fixed rod.

[0012] As a preferred implementation, a contact rod is fixedly connected to the outer side of the movable block above the second damping spring, and one end of the fixed rod away from the fixed block is fixedly connected to the movable block.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:
