DETAILED DESCRIPTION

[0021] The following will be combined with the attached embodiment of the present utility model Figure 1-5, clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] like Figures 1 to 5 As shown, the utility model discloses a shock-absorbing and cushioning packaging bag, comprising a bag body 1, wherein a cushioning sleeve 2 is fixedly connected inside the bag body 1, and a plurality of sliding tubes 21 are fixedly connected to the lower end of the cushioning sleeve 2, and the lower ends of the sliding tubes 21 penetrate and extend to the bottom of the bag body 1. Furthermore, a chassis 3 is provided below the cushioning sleeve 2, and a plurality of cushioning mechanisms are movably connected between the chassis 3 and the sliding tubes 21. Furthermore, an intermediate plate 4 is fixedly connected to the lower end of the bag body 1, and a plurality of stabilizing air bags 41 for stabilizing the bag body 1 are fixedly connected between the lower end surface of the intermediate plate 4 and the upper end surface of the chassis 3.

[0024] The side wall of the buffer sleeve 2 is made of high-density polyethylene, and a plurality of air-filled buffer balloons 22 are fixedly connected to the inner wall of the buffer sleeve 2. The high-density polyethylene has good wear resistance and toughness, low permeability to water vapor and air, and poor water absorption. Together with the buffer balloons 22, the dry goods in the bag body 1 can bear most of the impact force. In addition, a plurality of shock-absorbing airbags 12 are fixedly connected to the outer wall of the bag body 1 to assist the buffer balloons 22 in reducing the external impact force on the dry goods in the bag body 1.

[0025] Furthermore, the bottom material of the buffer sleeve 2 is low-density polyethylene. Low-density polyethylene has good softness and extensibility, and can also resist a certain impact force for the dry goods in the bag body 1 during transportation. The above structure protects the dry goods from being broken due to side collision during transportation.

[0026] Furthermore, the buffer mechanism includes a sliding rod 31 and a return spring 32 (compression spring), the sliding rod 31 is fixedly connected to the upper end of the chassis 3, the sliding tube 21 is slidably connected to the sliding rod 31, and the return spring 32 is fixedly connected between the sliding rod 31 and the sliding tube 21.

[0027] Furthermore, the intermediate plate 4 has an air cavity 42 at the upper end of the stabilizing airbag 41, an air inlet pipe 43 at the upper end of the air cavity 42, and a connecting pipe 44 at the upper end of the air inlet pipe 43. Both ends of the connecting pipe 44 pass through the intermediate plate 4 and are connected to the atmosphere.

[0028] When the bag body 1 encounters bumps in the cardboard box, the bag body 1 drives the sliding tube 21 to move on the sliding rod 31, and relies on the return spring 32 for buffering, thereby protecting the dry goods from being damaged by the up and down bumps caused by the bumpy journey. When the buffer mechanism buffers, since there is a certain gap between the sliding rod 31 and the sliding tube 21, the air in the sliding tube 21 will be squeezed out when the sliding rod 31 moves downward, thereby playing a certain role in stabilizing the sliding rod 31;

[0029] In addition, the stabilizing airbag 41 in the utility model acts as a damping mechanism of the buffer mechanism. When the stabilizing airbag 41 is compressed and reset, air enters and exits the connecting pipe 44 through the air inlet pipe 43. The stabilizing airbag 41 in the utility model is mainly used to stabilize the bag body 1. During the slow compression process of the stabilizing airbag 41, the bag body 1 is stabilized to prevent the bag body 1 from shaking drastically.

[0030] In addition, the upper end of the bag body 1 is provided with a plurality of holes 11 for threading ropes, so that the packing personnel can thread ropes to close the upper end of the bag body 1 after the dry goods are packed, so as to prevent the dry goods from spilling out of the upper end of the bag body 1. In actual transportation, after each bag body 1 is sealed, the packing personnel will put the packed dry goods into a cardboard box. A cardboard box usually contains 5-10 bags, and each bag of dry goods is separated by a partition. After the dry goods are packed, the packing personnel will seal the cardboard box. It should be noted here that the cardboard boxes should be transported with the front side facing up (that is, the bottom plate 3 facing down) and placed and stacked neatly.

[0031] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
