The terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0027] like Figure 1-4 As shown, this utility model provides a technical solution: an airport checked baggage anti-collision device, including a base 1, with multiple threaded holes on the corresponding side of the two bases 1, the two bases 1 cooperating, and a first threaded rod 2 connected to the inside of the threaded hole, so as to realize the splicing between the two bases 1 through the first threaded rod 2, which makes it easier to clean the inside of the base 1 and maintain the overall structure during long-term use.

[0028] A fixing component is fixedly installed on the top of the base 1. A fixing steel pipe 3 is set on the side of the fixing component away from the base 1. The fixing steel pipe 3 has a fixing groove inside. A connector 4 is movably connected to the top of the fixing steel pipe 3. The connector 4 is adapted to the fixing groove. A fixing hole is opened inside the connector 4. A fixing buckle 5 is set inside the fixing hole. An anti-collision sponge 18 is fixedly installed on the top of the connector 4. The two bases 1 are spliced ​​and fixed through the threaded holes on the corresponding sides and the first threaded rod 2. The spacing can be flexibly adjusted according to the size of the suitcase. The fixing steel pipe 3 provides the installation position for the connector 4. After the connector 4 is inserted into the fixing groove, the fixing buckle 5 is inserted into the fixing hole to firmly fix the connector 4 on the fixing steel pipe 3. When the top of the suitcase is hit, the anti-collision sponge 18 contacts the impact object first. Its elasticity can absorb and buffer the impact energy, reduce the direct impact on the suitcase, and protect the items in the suitcase.

[0029] The base 1 contains multiple shock-absorbing components. A buffer block 6 is located on the side of the shock-absorbing components away from the base 1. Multiple first springs 7 are fixedly installed on the side of the buffer block 6 away from the shock-absorbing components. A buffer pad 8 is fixedly connected to the end of the first spring 7 away from the buffer block 6. The outer surface of the buffer pad 8 has anti-slip textures. When the suitcase is subjected to a side impact or vibration, the buffer pad 8 first contacts the external object. The anti-slip textures on its surface increase friction, preventing the suitcase from sliding. After being subjected to force, the buffer pad 8 compresses the first springs 7. The elastic deformation of the first springs 7 absorbs and buffers part of the impact energy, while simultaneously transferring the force to the buffer block 6. The buffer block 6 then transfers the force to the shock-absorbing components, providing initial cushioning and reducing the degree of vibration in the suitcase. The fixing components include a fixing seat 9, a fastening block 10, a second threaded rod 11, and a knob 12. The bottom of the fixing seat 9 is fixedly connected to the top of the base 1. The inner surface of the fixing seat 9 has a "wave-shaped" structure. The side of the fixing seat 9 away from the "wave-shaped" structure is threaded... A second threaded rod 11 is connected, and a fastening block 10 is rotatably connected to the end of the second threaded rod 11 near the "wave-shaped" structure. The side of the fastening block 10 away from the second threaded rod 11 is also a "wave-shaped" structure. The fastening block 10 and the fixing seat 9 cooperate with each other. A knob 12 is coaxially fixed to the end of the second threaded rod 11 away from the fastening block 10. Rotating the knob 12 drives the second threaded rod 11 to rotate. Since the second threaded rod 11 is rotatably connected to the fastening block 10, the fastening block 10 will not rotate with the second threaded rod 11, but will move towards or away from the fixing seat 9 under the push of the second threaded rod 11. When the fastening block 10 moves closer to the fixing seat 9, the two "wave-shaped" structures gradually clamp the fixing steel pipe 3. The friction is increased by the contact between the "wave-shaped" structure and the outer circumference of the fixing steel pipe 3, so as to achieve a stable fixation of the fixing steel pipe 3. When it is necessary to adjust or disassemble the fixing steel pipe 3, the knob 12 is rotated in the opposite direction, the fastening block 10 moves away from the fixing seat 9, and the clamping of the fixing steel pipe 3 is released.

[0030] The shock-absorbing assembly includes a support sleeve 13, a second spring 14, and a third spring 15. One end of the support sleeve 13 is fixedly connected to the interior of the base 1. The second spring 14 is installed inside the support sleeve 13, and one end of the second spring 14 is fixedly connected to the interior of the base 1. The third spring 15 is installed inside the support sleeve 13 and is fixedly connected to the end of the support sleeve 13 away from the second spring 14. The support sleeve 13 provides installation space and support for the second spring 14 and the third spring 15. When the suitcase is subjected to vibration or impact, the force is transmitted to the shock-absorbing assembly through the buffer block 6. The second spring 14 and the third spring 15 are compressed, and their elastic deformation can absorb and buffer the impact energy, reducing the impact of the impact on the suitcase and playing a shock-absorbing role. At the same time, the shock-absorbing assembly works in conjunction with the function of fixing the steel pipe 3 to ensure the safety of the suitcase during transportation. The shock-absorbing assembly also includes a shock-absorbing head 16 and a buffer plate 17. The shock-absorbing head 16 is slidably connected inside the support sleeve 13. One end of the shock absorber 16 is fixedly connected to the end of the second spring 14 away from the base 1. The third spring 15 is sleeved on the outer periphery of the shock absorber head 16. The end of the shock absorber head 16 away from the support sleeve 13 is fixedly connected to a buffer plate 17. The side of the buffer plate 17 away from the shock absorber head 16 is fixedly connected to the side of the buffer block 6. When the shock absorber head 16 slides inside the support sleeve 13, the third spring 15 will also be compressed or stretched. When the suitcase is subjected to impact, the second spring 14 and the third spring 15 work together to absorb and disperse the impact energy. The third spring 15 is sleeved on the outer periphery of the shock absorber head 16, which can limit the sliding range of the shock absorber head 16 and prevent it from falling out of the support sleeve 13, ensuring the normal operation of the shock absorber assembly. At the same time, the third spring 15 can also increase the elastic recovery ability of the shock absorber assembly, so that the shock absorber head 16 can quickly return to the initial position after being impacted, preparing for the next shock absorption. The fixed assembly provides a solid foundation for the entire shock absorption and anti-collision structure by fixing the fixed steel pipe 3, ensuring that the suitcase is fully protected during transportation.

[0031] The working process of this utility model:

[0032] Step 1: According to the size of the suitcase, place the two bases 1 correspondingly, aligning the threaded holes on their corresponding sides. Then, screw the first threaded rod 2 into the threaded hole to fix the two bases 1 together. Adjust the spacing of the bases 1 to fit the suitcase. Place the fixing steel pipe 3 on the fixing component position at the top of the base 1. The inner side of the fixing seat 9 of the fixing component has a "wave-shaped" structure, which initially fits against the outer circumference of the fixing steel pipe 3. Rotate the knob 12 on the fixing component to drive the second threaded rod 11 to rotate. Since the second threaded rod 11 is rotatably connected to the fastening block 10, the fastening block 10 will not rotate with the second threaded rod 11, but will move towards the fixing seat 9 under the push of the second threaded rod 11. When the fastening block 10 approaches the fixing seat 9, the "wave-shaped" structure on the fastening block 10 and the "wave-shaped" structure on the fixing seat 9 gradually clamp the fixing steel pipe 3. By using the fit between the "wave-shaped" structure and the outer circumference of the fixing steel pipe 3, the friction is increased, thereby firmly fixing the fixing steel pipe 3 on the base 1.

[0033] Step 2: Align the connector 4 with the fixing groove inside the fixing steel pipe 3, insert the connector 4 into the fixing groove, and after the connector 4 is inserted into the fixing groove, insert the fixing buckle 5 into the fixing hole inside the connector 4 to make the connector 4 firmly fixed on the fixing steel pipe 3. At this time, the anti-collision sponge 18 fixedly installed on the top of the connector 4 is located above the suitcase, providing anti-collision protection for the top of the suitcase.

[0034] Step 3: When the suitcase is subjected to a side impact or vibration, the cushioning pad 8 first comes into contact with the external object. The anti-slip texture on the outer surface of the cushioning pad 8 increases friction and prevents the suitcase from sliding. After being subjected to force, the cushioning pad 8 compresses the first spring 7, causing the first spring 7 to undergo elastic deformation, absorbing and buffering part of the impact energy, while simultaneously transferring the force to the buffer block 6. The buffer block 6 then transfers the force to the shock-absorbing assembly. The buffer plate 17 in the shock-absorbing assembly pushes the shock-absorbing head 16 to slide within the support sleeve 13. During the sliding process of the shock-absorbing head 16, the second spring 14 and the third spring 15 are compressed or stretched. Working together, they absorb and disperse impact energy, reducing the impact on the suitcase and playing a shock-absorbing role. The third spring 15 is sleeved on the outer periphery of the shock absorber head 16, which can limit the sliding range of the shock absorber head 16 and prevent it from falling out of the support sleeve 13, ensuring the normal operation of the shock-absorbing component. At the same time, it increases the elastic recovery ability of the shock absorber component, so that the shock absorber head 16 can quickly return to the initial position after being impacted, preparing for the next shock absorption. The fixed component stably fixes the fixed steel pipe 3, providing a solid foundation for the entire shock absorption and anti-collision structure, ensuring that the suitcase is fully protected during transportation.
