Description

Technical Field

[0001] This utility model relates to the technical field of trolley bags, specifically trolley bags with concealed trolley handles. Background Technology

[0002] A rolling suitcase is a type of luggage with a pull handle and wheels, and it is widely used because of its ease of use.

[0003] A search revealed a Chinese patent publication number CN219762671U, which discloses a trolley bag with a concealed pull rod. The bag's outer wall is equipped with multiple cushioning components, each including a positioning ring and a base. The positioning ring is fixed to the outer wall of the bag, and the base has a cushioning groove inside. A cushioning spring is located inside the cushioning groove, with one end fixed to the groove and the other end fitted with a cushioning block. When the bag experiences bumps during transport, the cushioning block compresses the spring within the groove, causing it to rise and fall within the groove. This provides cushioning during transport, preventing hard resonance between the bag and the transport vehicle and protecting the contents from damage due to excessive vibration. The design is highly practical.

[0004] However, when using the trolley handle, the user needs to pull out the upper part of the handle, and sometimes needs to tilt or move the trolley handle upright. This will cause friction between the hand and the handle. Long-term use will cause wear and tear on the upper part of the trolley handle and make the user's hand uncomfortable. Utility Model Content

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. Example 1:

[0016] Please see Figure 1-4This utility model provides a concealed pull rod luggage, including a luggage 1 and a pull rod 3. A groove 2 is provided inside the upper front side wall of the luggage 1. A pull rod 3 is symmetrically slidably connected inside the lower end of the groove 2. A rotating roller 4 connects the two pull rods 3. A moving groove 5 is provided on the side wall of each of the two pull rods 3. A pressing plate 8 is slidably connected inside the moving groove 5. A limiting post 9 is fixedly installed on one side wall of each pressing plate 8, and a first tension spring 6 is symmetrically fixedly installed between the other side wall and the side wall of the moving groove 5. The limiting post 9 penetrates the side wall of the moving groove 5 and extends to the outside of the pull rod 3. Limiting holes 11 are provided inside the side walls of both ends of the rotating roller 4, and the limiting post 9 is slidably connected inside the limiting holes 11. A telescopic rod 7 is symmetrically fixedly installed between the side wall of the pressing plate 8 and the side wall of the moving groove 5. The retractable rods 7 are symmetrically arranged at both ends of the first tension spring 6. The diameter of the limiting post 9 matches the diameter of the limiting hole 11. The top surface of the retracted pull rod 3 is horizontal with the bottom of the bag 1. When using the main body of the trolley case, pull the rotating roller 4 upward to move the pull rod 3 upward, which can easily remove the pull rod 3. The user holds the rotating roller 4, and the position of the pull rod 3 does not require an unlocking function. The position of the pull rod 3 is moved entirely by the sliding force between the pull rod 3 and the bag 1, which is convenient to extend and shorten according to the length of the user's arm. When tilting the main body of the trolley case, simply hold the rotating roller 4 normally and tilt the main body of the trolley case. The main body of the trolley case can be tilted easily without causing friction between the rotating roller 4 and the palm, thus protecting the hand. Example 2:
