Description

Technical Field

[0001] This utility model relates to the field of trolley case technology, specifically to a trolley case with an external hook structure. Background Technology

[0002] A rolling suitcase refers to a suitcase equipped with a pull handle and wheels. It is widely used due to its convenience. The pull handle makes it easy to drag while walking, greatly reducing the burden. Furthermore, for added convenience, many rolling suitcases on the market are designed with external hooks. These hooks can be used to hang shopping bags, clothing, and other small items, preventing them from shifting during travel and ensuring that items inside the suitcase don't scatter due to bumps. In addition, hooks help car owners make better use of the suitcase space, securing irregularly shaped items and making more efficient and organized use of the space.

[0003] A search revealed a trolley case with retractable hooks in application document CN222707725U. This trolley case is designed to be placed vertically with the casters on the ground and the retractable hooks on the side wall of the case erected vertically. To hang items on the retractable hooks, the hook head is pulled upwards, simultaneously moving the telescopic rod upwards. This causes the first slot on the side wall of the telescopic rod to disengage from a locking block, forcing the locking block spring to press against the inner wall of the housing. The upward movement continues until the locking block engages with the second slot on the side wall of the telescopic rod. Simultaneously, the locking block spring relaxes towards the telescopic rod, allowing the locking block to enter the second slot. During this process, the base spring relaxes, providing additional upward force to the telescopic rod, ensuring the upper surface of the limiting support aligns with the protruding part inside the housing for support. Items to be hung can then be placed on the upward-extending hook head.

[0004] However, there are still some defects and shortcomings that need to be optimized, as follows: After the hook head of the trolley case with retractable foot hook pops out, the gap between it and the trolley case is fixed and relatively narrow. At this time, the objects that can be hung are limited, and the practicality is reduced. Therefore, it is necessary to design a trolley case with an external hook structure to solve the problems mentioned in the background technology. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] This utility model embodiment provides a trolley case with an external hook structure. The trolley case with an external hook structure effectively solves the technical problem that in existing trolley cases with retractable foot hooks, the gap between the hook head and the trolley case is fixed and narrow after the hook head pops out, which limits the objects that can be hung and reduces practicality.

[0026] Please see Figures 1-6 This utility model provides a technical solution:

[0027] A trolley case with an external hook structure includes a main body 1 and an external hook structure 2. Lockable casters 11 are movably installed at the four corners of the bottom of the main body 1. A retractable pull rod 12 is movably installed at the center of the back of the main body 1 near the top. The design of the lockable casters 11 and the retractable pull rod 12 facilitates the movement of the main body 1.

[0028] The external hook structure 2 includes a box stand 21 fixedly installed on one side of the main box 1, and a hook body 22 is rotatably installed on the bottom of the box stand 21.

[0029] The hook body 22 includes a horizontal bar 221, a vertical bar 222 fixedly installed at one end of the horizontal bar 221, and a rotating seat 223 fixedly installed at the end of the horizontal bar 221 away from the vertical bar 222. The rotating seat 223 is movably connected to the box stand 21 through an automatic reset component 224. In use, the hook body 22 can be flipped outward from the bottom of the box stand 21. At this time, the hook body 22 rotates around the rotating seat 223 as the axis under the action of the automatic reset component 224. At the same time, the distance between the hook body 22 and the main box 1 can be adjusted according to the object to be hung. After reaching the appropriate distance, the object to be hung can be directly hung on the horizontal bar 221. The vertical bar 222 can limit it to prevent it from falling off. Moreover, the design of the external hook structure 2 makes the distance between the hook body 22 and the main box 1 after it is rotated and unfolded adjustable, which is suitable for hanging different objects, overcomes limitations, and improves practicality.

[0030] Furthermore, in this embodiment, please refer to Figure 2 and Figure 4 The external hook structure 2 is rectangular in shape and has four sets. The four sets of external hook structures 2 are located on one side of the main box 1 near the four corners. The horizontal bar 221 and the vertical bar 222 are L-shaped. By setting the external hook structure 2 in a rectangular shape and having four sets, it can achieve multiple functions. It can not only hang objects for convenient storage and management, but also be used as a support foot for the main box 1, making it highly practical.

[0031] Furthermore, in this embodiment, please refer to Figure 5 and Figure 6The automatic reset assembly 224 includes a rotating shaft 2241 fixedly installed at the center of the top surface of the rotating base 223 and a spring mounting shaft 2242 fixedly installed inside the housing foot base 21. The rotating shaft 2241 is composed of a connecting base 22411 and a shaft body 22412. The shaft body 22412 is fixedly connected to the top surface of the rotating base 223 via the connecting base 22411. The rotating shaft 2241 and the spring mounting shaft 2242 are movably connected via a transmission component 2243. The transmission component 2243 is composed of an annular sleeve 22431 fixedly fitted on the outer surface of the shaft body 22412 and a reset spring 22432 movably fitted on the outer surface of the spring mounting shaft 2242. The reset spring 22432 has a positioning end 22 near the spring mounting shaft 2242. 433, the end of the return spring 22432 away from the annular sleeve 22431 is provided with a movable end 22434, and the movable end 22434 is fixedly connected to the annular sleeve 22431. When unfolded, under the action of the rotating seat 223, the rotating shaft 2241 drives the annular sleeve 22431 to rotate. Then, under the action of the return spring 22432's rotational torque, the rotating seat 223 automatically resets, thereby driving the hook body 22 to reset and close with the box stand 21. This not only gives the hook body 22 the function of automatic reset, but also allows it to clamp and limit the suspended object, further preventing it from falling off, making it more stable and reliable. At the same time, the annular sleeve 22431 can not only transmit power, but also limit the shaft 22412, effectively preventing the rotating seat 223 from detaching.

[0032] Furthermore, in this embodiment, please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The bottom surface of the box stand 21 near the rotating seat 223 has a rotating cavity 211 that matches it. The inside of the box stand 21 near the top of the rotating cavity 211 has a movable shaft groove 212 that matches the rotating shaft 2241. The inner wall of the movable shaft groove 212 has an anti-detachment ring groove 213 that matches the annular sleeve 22431. The inside of the box stand 21 near the movable shaft groove 212 away from the hook body 22 has a spring groove that matches the reset spring 22432. The spring mounting shaft 2242 is located inside the spring groove. The design of the rotating cavity 211, movable shaft groove 212, anti-detachment ring groove 213 and spring groove facilitates the installation of the automatic reset component 224.

[0033] It should be noted that locking casters and retractable rods are existing technologies, and will not be discussed in detail here.

[0034] In this embodiment, the specific implementation scenario is as follows: When in use, the hook body 22 can be flipped outward from the bottom of the box stand 21. At this time, the hook body 22 rotates around the rotating seat 223 as the axis under the action of the automatic reset component 224. At the same time, the distance between the hook body 22 and the main box 1 can be adjusted according to the object to be suspended. After reaching the appropriate distance, the object to be suspended can be directly suspended on the horizontal bar 221. Meanwhile, the vertical bar 222 can limit it to prevent it from falling off. Compared with the existing trolley cases with retractable stand hooks, the design of the external hook structure 2 allows the distance between the hook body 22 and the main box 1 to be adjustable after the hook body 22 is rotated and unfolded, which is suitable for suspending different objects, overcomes limitations, and improves practicality.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
