Abstract
Description
Technical Field
[0001] This utility model relates to the field of trolley case technology, specifically a hand-held trolley case. Background Technology
[0002] A rolling suitcase is a type of luggage equipped with a pull handle and wheels. It is widely used due to its convenience. Rolling suitcases are further categorized by the pull handle: single-tube and double-tube handles are available. The handle itself can also be square or round, making it easier to drag while walking and significantly reducing the burden. Rolling suitcases can be carried by hand or pulled.
[0003] A search revealed Chinese patent CN211747478U, which discloses a shockproof and easy-to-carry trolley case. The case includes a main body, with casters installed at the four corners of the bottom of the main body. Each caster has a pushrod, and a mounting base is provided between the casters and the main body. The mounting base includes a sleeve, a pushrod, a shock-absorbing rubber sleeve, and a shock-absorbing spring.
[0004] The device works by mounting the casters on the inserts inside the mounting base and installing shock-absorbing rubber sleeves at the bottom periphery of the inserts. A shock-absorbing spring is installed at the top of the inserts. This allows the vibration force generated by the casters rolling on the ground to be slowed down and absorbed by the shock-absorbing rubber sleeves and springs, thereby reducing the vibration of the suitcase body.
[0005] However, the device still has the following problems. The top of the device is equipped with a main handle and a pair of auxiliary handles to improve the convenience of pulling or carrying the device. However, in actual use, suitcases are tools used for travel or business trips and often need to go through security checks. Some security checkpoints have conveyor belts designed to be positioned high, making it difficult for users with less strength to lift the device using the main handle or auxiliary handles, which makes the device inconvenient to use.

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example: Figure 1 As shown, a hand-held trolley case includes an outer shell 1, with a lid 2 hinged to one end of the outer shell 1, and a zipper installed between the lid 2 and the outer shell 1. Both the outer shell 1 and the lid 2 are made of composite organic materials, which have the characteristics of high compressive strength and good support, thereby improving the overall structural strength of the device and reducing the weight of the device. It also includes a support component and a protective component set at the other end of the outer shell 1.
[0026] like Figures 1-3As shown, in one embodiment, to improve the ease of use of the device, the support assembly includes an inner box 4 fixedly connected to the inner wall of the outer shell 1. A sliding frame 5 is slidably connected to the outer wall of the inner box 4. A telescopic membrane 6 is fixedly connected between the sliding frame 5 and the outer shell 1, wherein the telescopic membrane 6 serves to seal and improve aesthetics. A rotating shaft 8 is fixedly connected to one side of the outer wall of the sliding frame 5. A pair of support rods 9 are rotatably connected to both ends of the rotating shaft 8. A support foot 11 is hinged to one end of each support rod 9. A pair of support folding rods 10 are installed between the outer wall of each support rod 9 and the outer wall of the sliding frame 5, wherein the support folding rods 10 serve to lock the support rod 9 and the sliding frame 5. A pair of support folding rods 10 are installed between the outer wall of each support foot 11 and the outer wall of the support rod 9. Rod 2 12, through the cooperation between support rod 9 and support foot 11, facilitates lifting the device with less effort, improving the convenience of the device. A handle 15 is fixedly connected to the top side of the sliding frame 5, and a second handle 20 is fixedly connected to the outer wall side of the box cover 2. One end of a pair of support rods 9 is fixedly connected to a reinforcing frame 13, which enhances the stability of the support rods 9. Multiple lining bags 14 are fixedly connected to the inner wall of the reinforcing frame 13. The lining bags 14 facilitate the placement of small items, improving the space utilization and practicality of the device. A first handle 3 is fixedly connected to the top side of the outer shell 1. A pair of universal casters with brakes 16 are mounted on the bottom of both the outer shell 1 and the bottom of the sliding frame 5. The universal casters with brakes 16 enhance the mobility of the device.
[0027] like Figure 3 and Figure 4 As shown, in one embodiment, to further improve the convenience of the device, the protective component includes a buffer net 7 fixedly connected to one end of the inner wall of the sliding frame 5. One end of the buffer net 7 is fixedly connected to a plurality of guide rods 18. The outer wall of the inner box 4 is fixedly connected to a plurality of guide sleeves 17 adapted to the guide rods 18, and one end of the guide sleeve 17 is slidably connected to one end of the guide rod 18. A spring 19 is sleeved between the outer peripheral wall of each guide rod 18 and the guide sleeve 17. Through the mutual cooperation between the guide rod 18, the guide sleeve 17 and the spring 19, it is easy to drive the buffer net 7 and the sliding frame 5 to move, absorb part of the potential energy of the device tipping over, and ensure the safety of the objects placed inside the device.
[0028] Working principle: In use, pull the device by handle 15 or handle 3, and the universal wheel with brake 16 will move the device to the security checkpoint. Then pull the support rod 9, causing it to rotate around the rotating shaft 8 to a specified angle, locking the folding support rod 10. Then pull the support foot 11, locking the folding support rod 12. Finally, pull the handle 15 and handle 20 to slowly tilt the device towards the support rod 9, causing the support foot 11 to touch the ground. Utilizing the lever principle, the device tilts between the support rod 9 and the support foot 11. The coordinated action of the two parts lifts the handle 20, causing the device to rotate around the rotating shaft 8, making it easier to lift the device. This allows even users with less strength to easily place the device on the security conveyor belt, effectively improving the ease of use of the device. When the supporting folding rod 10 or the supporting folding rod 22 is damaged, there is a risk of the device tipping over. Through the coordination between the guide rod 18, the guide sleeve 17, and the spring 19, the buffer net 7 and the sliding frame 5 slide, absorbing part of the potential energy of the device tipping over and ensuring the safety of the objects placed inside the device.
