[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a foldable cushioning EPE pearl cotton, including pearl cotton sheet 1 and pearl cotton sheet 2, low-density polyethylene (LDPE) as the main raw material, through the physical foaming process to produce countless independent bubbles, the right side of the pearl cotton sheet 1 and the right side of the pearl cotton sheet 2 are hinged, the pearl cotton sheet 1 and the pearl cotton sheet 2 are connected by a connecting mechanism, the EPE pearl cotton material is light and has a certain flexibility, can be easily folded and stored, reducing storage space occupancy, easy to transport and carry, the connecting mechanism The connection includes a connecting box 3, a Velcro mother tape 4 and a Velcro father tape 5. The connecting box 3 is fixedly installed on the front of the pearl cotton sheet 1, and the Velcro mother tape 4 is arranged inside the connecting box 3. One end of the Velcro father tape 5 is fixedly connected to the back of the pearl cotton sheet 2 2. The Velcro mother tape 4 and the Velcro father tape 5 cooperate with each other. The other end of the Velcro father tape 5 and the Velcro mother tape 4 are detachably connected. Through the cooperation of the Velcro mother tape 4 and the Velcro father tape 5, the pearl cotton sheet 1 1 and the pearl cotton sheet 2 2 can be rotated, folded and fixed. A control mechanism is provided inside the connecting box 3.

[0032] Reference Figure 3 、 Figure 4 The control mechanism includes a reel 6 for rewinding the Velcro tape 4. The surface of the reel 6 is fixedly connected to the end of the Velcro tape 4 away from the Velcro tape 5. The Velcro tape 4 is wrapped around the circumferential surface of the reel 6. By controlling the number of rotations of the reel 6, the length of the Velcro tape 4 extending out of the reel 6 can be conveniently controlled. The control mechanism also includes a rotating shaft 7 arranged in a vertical state. The rotating shaft 7 is rotatably mounted on the inner wall of the connecting box 3. The reel 6 is fixedly mounted on the circumferential surface of the rotating shaft 7. The surface of the rotating shaft 7 is elastically connected to the inner wall of the connecting box 3 through a spiral spring 8. By setting the spiral spring 8, the rotating shaft 7 has a tendency to rotate clockwise, so that the reel 6 can tighten the Velcro tape 4.

[0033] Reference Figure 3 、 Figure 4The control mechanism also includes a disc 9, which is fixedly mounted on the circumferential surface of the rotating shaft 7. A control groove 10 and a control groove 2 11 are provided on the circumferential surface of the disc 9. The inner walls of the control groove 10 and the control groove 2 11 are both provided with inclined surfaces. The number of control grooves 10 and control grooves 2 11 is set to multiple, and multiple control grooves 10 and multiple control grooves 2 11 are arranged in a ring shape at equal angles on the circumferential surface of the disc 9. The control mechanism also includes a pull ring 12, and a control block 13 is connected to the left side of the pull ring 12. The end of the control block 13 away from the pull ring 12 is provided with an arc-shaped dome surface. The control block 13 is slidably mounted on the inner wall of the connecting box 3. The sliding direction of the control block 13 is left and right sliding. The control block 13 is elastically connected to the inner wall of the connecting box 3 through a reset spring 14, and the reset spring 14 applies an elastic force toward the left to the control block 13.

[0034] Reference Figure 1 、 Figure 2 The front of the pearl cotton sheet 1 and the back of the pearl cotton sheet 2 are fixedly connected with a cushioning airbag 15, and the interior of the pearl cotton sheet 1 and the interior of the pearl cotton sheet 2 are both provided with honeycomb holes 16. The number of honeycomb holes 16 is set to multiple. These honeycomb holes 16 can effectively disperse and absorb energy when impacted by external force, and have a good cushioning and protective effect. The side where the pearl cotton sheet 1 and the pearl cotton sheet 2 are close to each other is provided with a cavity 17, which can soundproof and heat-insulate, reduce noise and heat transfer, and make it have excellent cushioning, protection and heat-insulating properties.

[0035] Working principle: When in use, fold the pearl cotton sheet 1 and the pearl cotton sheet 2, and then pull the pull ring 12 to the right. The movement of the pull ring 12 drives the control block 13 to overcome the elastic force of the reset spring 14 and move to the right, thereby making the control block 13 break away from the contact with the disk 9. At this time, the rotating shaft 7 can rotate freely, and then pull out the Velcro mother tape 4, extend the length of the Velcro mother tape 4 extending outside the connecting box 3, and then fit the Velcro mother tape 4 on the surface of the Velcro father tape 5, so that the pearl cotton sheet 1 and the pearl cotton sheet 2 2 are fixed, thereby improving the stability of the connection between the pearl cotton sheet 1 and the pearl cotton sheet 2 2.

[0036] After fixing the pearl cotton sheet 1 and the pearl cotton sheet 2, release the pull ring 12, so that the control block 13 moves to the left under the elastic force of the reset spring 14, and then the control block 13 is inserted into the inside of the control groove 2 11, preventing the retractor 6 from rotating counterclockwise, which can prevent the Velcro mother tape 4 from extending too long from the connection box 3, causing the pearl cotton sheet 1 and the pearl cotton sheet 2 2 to separate from each other, thereby improving the stability of the connection.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
