Description

Technical Field

[0001] This utility model relates to the field of luggage accessories technology, specifically to a quick-release structure for luggage wheels. Background Technology

[0002] Bag wheels are among the fastest-wearing parts of bags. However, most existing bags have non-removable wheels, making it inconvenient to inspect and replace them. When the main body of the bag is intact, but the wheels are worn out and cannot be used normally, replacing them requires removing them from the bag. This disassembly process is complicated and may damage the appearance of the bag, affecting its aesthetics and causing inconvenience to the user. This makes it difficult for people to continue using the bag and reduces its practicality.

[0003] To address the aforementioned issues, a detachable bag wheel structure, disclosed in publication number "CN220631331U", includes a movable wheel insert base and a movable wheel body. The top of the movable wheel body has a connecting shaft. The movable wheel insert base has a vertically arranged mounting through hole and a horizontally arranged mounting cavity. The upper end of the connecting shaft is inserted into the mounting through hole. The movable wheel insert base has a locking wheel device for detachably connecting the movable wheel body and the movable wheel insert base. The locking wheel device includes a locking wheel plate, a spring, an inner cover, and a button. The locking wheel plate is movably installed within the mounting cavity, and its two sides are connected to the spring and the button, respectively.

[0004] However, during actual use, it was found that the force feedback when pressing the button to unlock and release the lock in the direction of the moving wheel insert was not direct enough, resulting in poor operation smoothness and convenience, which led to a poor user experience. In addition, if the button gets stuck when pressed and does not spring back to reset, it is difficult for the user to pry the button off the moving wheel insert. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a quick-release structure for luggage wheels that can improve the smoothness of operation and enhance the user's operating experience, in order to address the shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-release structure for luggage wheels, including a wheel seat and a wheel frame detachably disposed from the wheel seat. A movable wheel assembly is rotatably disposed at the lower end of the wheel frame, and a connecting shaft is disposed at the top of the wheel frame. A mounting hole is vertically disposed on the wheel seat for mounting the upper end of the connecting shaft. The wheel seat is characterized by: a mounting cavity extending horizontally to one side near the lower end of the mounting hole, communicating with the mounting hole; a locking structure capable of locking or unlocking with the connecting shaft is slidably disposed within the mounting cavity; a toggle button is linked to the lower end of the locking structure; and a sliding groove is provided at the lower end of the wheel seat for the toggle button to slide.

[0007] The above technical solution is as follows: Compared with the existing technology, the force feedback of pressing to unlock and releasing the lock is not direct enough during actual operation, and the smoothness and convenience of operation are poor. The present invention adopts the setting of a toggle button. Simply slide the toggle button left or right to drive the locking structure and the connecting shaft to lock or unlock. This can prevent the switch from getting stuck inside the wheel seat and being unable to be pulled out. At the same time, the toggle setting can improve the smoothness of operation and improve the user's operating experience.

[0008] A further feature of this invention is that: the outer wall of the connecting shaft is provided with an annular groove; the locking structure includes a locking member; one end of the locking member near the connecting shaft is provided with an arc-shaped engaging groove that can engage with the annular groove; the other end of the locking member is provided with an elastic member; the other end of the elastic member is provided with an inner cover; the inner cover can cover the opening of the mounting cavity located on the outer wall of the wheel seat.

[0009] The above technical solution is adopted: by sliding the toggle button, the locking part can be moved away from the connecting shaft, thereby causing the arc-shaped locking groove on the locking part to disengage from the annular groove on the connecting shaft. At this time, the elastic element is compressed, realizing the function of unlocking and quick release. During installation, simply insert the connecting shaft into the mounting hole, release the toggle button, and the elastic potential energy of the elastic element is released, causing the locking part to reset, thereby causing the arc-shaped locking groove to engage with the annular groove, realizing the function of locking.

[0010] A further feature of this invention is that: a toggle part is provided on the end face of the toggle button away from the locking member; two sets of first latching blocks are provided on the end face of the toggle button close to the locking member, and the first latching blocks are arranged in a mirror image; a first latching groove for the first latching blocks to engage is provided in the middle of the locking member; and a long groove for the first latching blocks to slide is provided on the sliding groove.

[0011] The above technical solution facilitates user operation through the setting of the toggle part, while the setting of the first buckle block and the first buckle groove facilitates assembly by the staff during the production process.

[0012] A further feature of this invention is that a protruding positioning post is provided on the end of the locking member away from the connecting shaft, and one end of the elastic member is sleeved on the positioning post, while the other end abuts against the inner cover.

[0013] The above technical solution facilitates the installation of elastic components and improves assembly convenience by using positioning posts.

[0014] A further feature of this invention is that: the inner cover has a second snap block at both ends facing the same side, and the mounting cavity has a second snap groove on its inner wall near the opening of the outer wall of the wheel seat, which engages with the second snap block.

[0015] The above technical solution facilitates the assembly of the inner cover onto the wheel seat by setting the second latching block and the second latching groove, thereby enabling it to cooperate with the locking and elastic components to achieve the effect of unlocking by pushing and releasing the lock.

[0016] A further feature of this invention is that the movable wheel set includes a first rotating wheel and a second rotating wheel, which are located on both sides of the wheel frame, and the first rotating wheel and the second rotating wheel are mounted on the wheel frame via a rotating shaft.

[0017] The above technical solution is adopted so that the first rotating wheel and the second transmission wheel can be installed on the wheel frame to ensure the effect of use.

The lower end of the locking structure 4 is linked to a toggle button 5. The lower end of the wheel seat 1 is provided with a sliding groove 13 for the toggle button 5 to slide.

[0028] like Figure 2-3 The outer wall of the connecting shaft 21 shown is provided with an annular groove 211. The locking structure 4 includes a locking member 41. One end of the locking member 41 near the connecting shaft 21 is provided with an arc-shaped locking groove 411 that can engage with the annular groove 211. The other end of the locking member 41 is provided with an elastic member 42. The other end of the elastic member 42 is provided with an inner cover 43. The inner cover 43 can cover the opening of the mounting cavity 12 located on the outer wall of the wheel seat 1.

[0029] like Figure 3-4 The toggle button 5 shown is provided with a toggle part 51 on the end face away from the locking member 41. The toggle button 5 is provided with two sets of first latching blocks 52 on the end face near the locking member 41, and the first latching blocks 52 are arranged in a mirror image. The locking member 41 is provided with a first latching groove 412 in the middle for the first latching blocks 52 to be latched. The slide groove 13 is provided with a long groove 131 for the first latching blocks 52 to slide.

[0030] like Figure 3 The locking element 41 shown has a protruding positioning post 413 on its end away from the connecting shaft 21. One end of the elastic element 42 is sleeved on the positioning post 413, and the other end abuts against the inner cover 43; as shown Figure 3 , 5 The inner cover 43 shown has a second snap block 431 at both ends facing the same side.
