[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0028] like Figures 1 to 5 As shown, a detachable luggage corner wheel includes: a connecting seat 2 for connecting to the luggage, a movable wheel 3, and a limiting piece 4. The connecting seat 2 has a receiving space 21 and a connecting hole 22 communicating with the receiving space 21. A connecting post 23 is provided at the bottom of the receiving space 21. A through hole 24 communicating with the receiving space 21 is opened on the side wall of the connecting seat 2, and a button 25 is slidably provided on the through hole 24. The movable wheel 3 has a connecting rod 31 and an annular limiting groove 311 is provided on the connecting rod 31. The connecting rod 31 can pass through the connecting hole 22, and the annular limiting groove 311 is located in the receiving space 21. One end of the limiting piece 4 is rotatably connected to the connecting seat 2. On the column 23, the limiting piece 4 rotates around the connecting column 23. The limiting piece 4 has a limiting part 41. The inner end of the button 25 abuts against the other end of the limiting piece 4. The button 25 drives the limiting piece 4 to move between a first position and a second position. In the first position, the limiting part 41 is located in the annular limiting groove 311. In the second position, the limiting part 41 is disengaged from the annular limiting groove 311. A protrusion 42 is provided at the end of the limiting piece 4 away from the connecting column 23. A compression spring 43 is sleeved on the protrusion 42. The other end of the compression spring 43 abuts against the limiting wall 211 of the accommodating space 21. The compression spring 43 is used to keep the limiting part 41 inserted into the annular limiting groove 311.
[0029] In this application, the connecting rod 31 of the movable wheel 3 is inserted into the connecting hole 22 of the connecting seat 2, so that the annular limiting groove 311 enters the accommodating space 21. At this time, due to the action of the compression spring 43, the limiting part 41 of the limiting piece 4 is pushed towards the annular limiting groove 311 and locked in it. One end of the compression spring 43 abuts against the protrusion 42 of the limiting piece 4, and the other end abuts against the limiting wall 211 of the accommodating space 21. Its elasticity makes the limiting part 41 fit tightly in the annular limiting groove 311, thereby fixing the movable wheel 3. The inner end of the button 25 contacts the other end of the limiting piece 4. When pressed by external force, button 25 does not function, and the entire structure is in a stable installation state. When it is necessary to disassemble the movable wheel 3, button 25 is pressed, and button 25 slides outward along the through hole 24. Its inner end pushes the limiting piece 4 to rotate around the connecting post 23, overcoming the elastic force of the compression spring 43, so that the limiting part 41 gradually comes out of the annular limiting groove 311. When button 25 is pressed for a sufficient stroke, the limiting part 41 completely disengages from the annular limiting groove 311, and the connecting rod 31 of the movable wheel 3 is no longer constrained by the limiting part. The movable wheel 3 can then be pulled out from the connecting hole 22 to complete the disassembly.
[0030] This detachable structure allows users to quickly replace the corner wheels themselves when they are damaged or depending on the usage scenario, without the need for complicated tools or professional repairs, greatly improving ease of use and flexibility.
[0031] Specifically, the limiting part 41 has a recessed surface 411 that adapts to the bottom surface of the annular groove, and the recessed surface 411 can fit the bottom surface of the annular groove.
[0032] The fit between the concave surface 411 and the bottom surface of the annular groove increases the contact area between the limiting part 41 and the annular limiting groove 311, thereby increasing the portion of the limiting part 41 that is engaged in the annular limiting groove 311. During the use of the bag, even if it is subjected to a large external impact, vibration or frequent turning force, the moving wheel 3 can be more stably connected to the connecting seat 2, effectively reducing the possibility of the moving wheel 3 shaking, displacing or even detaching relative to the connecting seat 2, thereby ensuring the stability and safety of the bag's movement.
[0033] Specifically, the inner end of the button 25 is provided with a ball part 251, which can abut against the limiting piece 4.
[0034] When the ball part 251 contacts the limiting piece 4, it is a point contact or a small area contact. Compared with other contact methods, the friction between the two can be significantly reduced during the process of the button 25 sliding and driving the limiting piece 4 to rotate. This not only makes the operation of the button 25 smoother and less strenuous, but also effectively reduces the wear of the parts caused by long-term friction, and extends the service life of the button 25 and the limiting piece 4. Furthermore, the ball part 251 can be made of metal.
[0035] Specifically, it also includes a limiting plate 5, which covers the connecting seat 2 to limit the height of the accommodating space 21.
[0036] The limiting plate 5 covers the connecting seat 2, which plays a role in encapsulating and integrating the internal structure of the entire corner wheel. It tightly binds the connecting seat 2, the limiting plate 4 and other components together, making the relative position between the components more stable and reducing the possibility of components becoming loose or misaligned due to external forces during the use of the bag.
[0037] Specifically, the connector 2 is provided with a receiving groove 26 for receiving the outer end of the button 25. In the first position, the outer end of the button 25 is located in the receiving groove 26.
[0038] When button 25 is in the first position, that is, when it is not pressed in the normal installation state, the outer end of button 25 is hidden in the receiving groove 26, so that the outer surface of the connector 2 remains flat and simple, and there are no protruding parts exposed.
[0039] Specifically, a limiting hole 51 is provided on the limiting plate 5, and the connecting rod 31 of the moving wheel 3 can be inserted into the limiting hole 51.
[0040] The limiting hole 51 on the limiting plate 5 provides precise positioning guidance for the connecting rod 31 of the moving wheel 3. During installation, it ensures that the moving wheel 3 is accurately installed in the predetermined position, making the relative positional relationship between the moving wheel 3 and the connecting seat 2 more accurate and stable. The limiting hole 51 plays an effective constraining role on the connecting rod 31, preventing the moving wheel 3 from displacing in the axial direction.
[0041] Specifically, the lower part of the limiting plate 5 is provided with a guide groove 52, and the inner end of the button 25 is located in the guide groove 52 and can slide along the guide groove 52.
[0042] The guide groove 52 provides a precise path guide for the sliding of the inner end of the button 25. During the process of pressing the button 25 to remove or install the moving wheel 3, the inner end of the button 25 can only move along the direction defined by the guide groove 52, which avoids the button 25 deviating from the predetermined trajectory due to external force or manufacturing errors of the parts.
[0043] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture, as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.
[0044] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the word "and / or" throughout the text means including three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
