[0031] 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.
[0032] like Figures 1 to 5As shown, a removable luggage corner wheel with locking function for easy installation includes: a connecting seat 2 for connecting to a luggage, a movable wheel 3, a limiting piece 4, a switch 5, a cover plate 6, and a first compression spring 7. 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 bottom wall 3111 of the connecting seat 2. The movable wheel 3 has a connecting rod 31 that can pass through the connecting hole 22. The connecting rod 31 has an annular limiting groove 311. The annular limiting groove 311 has a bottom wall 3111 and a first guide wall 3112. The bottom wall 3111 is connected to the first guide wall 3112. The end of the connecting rod 31 has a second guide wall 312. Both the first guide wall 3112 and the second guide wall 312 force the first limiting part. 41 moves away from connecting rod 31; one end of limiting plate 4 is rotatably connected to connecting post 23 so that limiting plate 4 rotates around connecting post 23. Limiting plate 4 has a first limiting part 41 and a limiting hole 42. Limiting plate 4 can switch between a limiting state and an unlocking state; switch 5 is slidably disposed at through hole 24 and passes through limiting hole 42. Switch 5 has a second limiting part 51. In the limiting state, the second limiting part 51 enters the limiting hole 42 and the first limiting part 41 enters the annular limiting groove 311; in the unlocking state, the second limiting part 51 disengages from the limiting hole 42 so that limiting plate 4 is released from the limiting state, and the first guide wall 3112 can force the first limiting part 41 to disengage from the annular limiting groove 311; cover plate 6 is fixed on base, and first compression spring 7 is disposed between switch 5 and cover plate 6 so that switch 5 moves away from cover plate 6.
[0033] In this application, the connecting seat 2 is connected to the bag through the connecting hole 22. The connecting rod 31 on the moving wheel 3 can pass through the connecting hole 22 and be fixed to the connecting seat 2. The moving wheel (3) can be locked or unlocked by rotating the limiting plate (4). The limiting plate 4 is provided with a first limiting part 41. By rotating the connecting post 23 and the limiting plate 4, the limiting plate 4 can be positioned in a specific position. When the second limiting part 51 of the switch 5 enters the limiting hole 42, the first limiting part 41 will be fixed in the annular limiting groove 311 to ensure that the wheel will not be easily disassembled.
[0034] When switch 5 is in the unlocked state, the second limiting part 51 disengages from the limiting hole 42, and the limiting piece 4 is unlocked. At this time, when the user pulls the moving wheel 3 outward, the first guide wall 3112 will force the first limiting part 41 to disengage from the annular limiting groove 311, so that the wheel can be removed. The first compression spring 7 applies elastic force to make switch 5 move away from the cover plate 6, ensuring that when the external force is released, the second limiting part 51 of switch 5 can automatically enter the limiting hole 42.
[0035] Moreover, during installation, it is only necessary to insert the connecting rod 31 of the movable wheel 3 into the connecting hole 22, and the second guide wall 312 forces the limiting piece 4 to move away from the connecting rod 31 until the first guide part of the limiting piece 4 enters the annular limiting groove 311. When it is necessary to remove the movable wheel, simply press the switch 5. When the second limiting part 51 on the switch 5 disengages from the limiting hole 42, the user can easily pull out the movable wheel. The first guide wall 3112 forces the limiting piece 4 to move away from the connecting rod 31, making the entire disassembly and installation process more convenient.
[0036] Specifically, it also includes a second compression spring 8, one end of which is connected to the limiting plate 4 and the other end is connected to the inner wall of the accommodating space 21, so that the limiting plate 4 rotates toward the connecting rod 31.
[0037] The second compression spring 8 increases the locking force of the limiting plate 4 by pushing the limiting plate 4 closer to the connecting rod 31. Without external force, the first limiting part 41 of the limiting plate 4 can always remain in the annular limiting groove 311. Even after the first guide wall 3112 and the second guide wall 312 are squeezed, it will reset when there is no squeezing.
[0038] Specifically, the second limiting part 51 protrudes toward the connecting rod 31.
[0039] This design allows for increased thickness in this direction, thereby increasing its resistance to compression.
[0040] Specifically, the cover plate 6 is provided with a receiving groove 61, and the second limiting part 51 can enter the receiving groove 61 after disengaging from the limiting hole 42.
[0041] The design of the receiving groove 61 provides an additional physical space to ensure that the second limiting part 51 can be firmly inserted into the groove after unlocking, which increases the stability of the second limiting part 51 after it is separated from the limiting hole 42. As a fixed space, the receiving groove 61 restricts the range of movement of the second limiting part 51 and prevents it from being excessively offset or misaligned.
[0042] Specifically, the switch 5 is provided with a third limiting part 52, the size of which is larger than the through hole 24, and the bottom of the connecting seat 2 is provided with a guide slide 25, and the third limiting part 52 is slidably assembled in the guide slide 25.
[0043] The third limiting part 52 is larger than the through hole 24, which prevents the switch 5 from coming out of the through hole 24. The sliding assembly of the third limiting part 52 ensures that the movement trajectory of the switch 5 is precisely controlled. Due to the guiding effect of the guide slide 25 on the third limiting part 52, the instability of the switch 5 during operation is avoided, the safety of the overall structure is increased, and the failure or damage caused by improper operation or external force is reduced.
