Description

Technical Field

[0001] This utility model relates to the field of luggage technology, specifically to a luggage with detachable wheels. Background Technology

[0002] A rolling suitcase is a type of luggage, specifically a suitcase with a pull handle and wheels. It is widely used due to its convenience. Rolling suitcases are further categorized by the pull handle: single-tube and double-tube handles. The handle tubes also come in square and round shapes to facilitate dragging while walking, greatly reducing the burden. Rolling suitcases can be carried by hand or pulled. The wheels of most rolling suitcases are located at the bottom.

[0003] In existing technologies, common bags have simple structures and incomplete functions. Because the multiple pulleys at the bottom are not detachable, after a long period of use, the pulleys are damaged or broken and cannot be removed and replaced, making the bags unusable, resulting in a waste of resources and low practicality and functionality.

[0004] A search revealed that patent application number 202321854099.2 discloses a bag with detachable wheels. In use, the user pulls the sleeve plate 4a7 upwards, causing the sleeve plate 4a7 to move the guide rods 4a2 on both sides along the grooves of the support base 7. The guide rods 4a2 then move the tapered rod 4a3, which in turn causes the spring 4a6 to stretch along the outer wall of the slide rod 4a4, simultaneously releasing the tapered rod 4a3 from the ball 4a1. Then, the user pulls the bag wheel 8, which causes the sleeve 4a5 to move along the circular groove of the support base 7. Simultaneously, as the sleeve 4a5 moves downwards, the sleeve... The limiting groove of the sleeve 4a5 compresses the corresponding ball 4a1 inward, thereby disassembling the damaged bag wheel 8. Then, the new bag wheel 8 is inserted into the circular groove of the support base 7 through the sleeve 4a5. The sleeve plate 4a7 is then released, and the tapered rod 4a3, under the influence of the spring force of the spring 4a6, compresses the multiple outer balls 4a1 to fit into the limiting groove of the sleeve 4a5, thus installing the bag wheel 8. This allows for individual replacement of the bag wheel 8 when it is damaged, improving the lifespan of the bag. However, this device lacks a protective sleeve plate, making the sleeve plate easily triggered accidentally. This means that during the use or carrying of the bag, if the sleeve plate is accidentally pulled or bumped, the disassembly mechanism may be accidentally activated, causing the bag wheel to be removed when not needed. This not only affects the normal use of the bag but may also cause instability or damage. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a bag with detachable wheels, thus solving the problems mentioned in the background art.

[0006] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0007] A bag with detachable wheels includes a bag body, a pull rod installed at the top of the bag body, a handle installed at the top of the pull rod, a handle installed on one side of the bag body, a mounting base installed at the bottom of the bag body, and a pulley module installed on the bag body via the mounting base;

[0008] The pulley module is provided with a plug-in seat, the pulley module is provided with a fixing frame, the top of the fixing frame is provided with a plug connector, the fixing frame is assembled with the plug-in seat through the plug connector, the plug-in seat is connected and fixed to the mounting base, the plug-in seat is provided with a pipe thread on the outside, a limit ring is installed on the outside of the plug-in seat through the pipe thread, and a sleeve is installed on the outside of the plug-in seat.

[0009] The fixed frame is rotatably mounted with rollers, and the connector is provided with a slot.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the inner side of the limiting ring is provided with threads, and the limiting ring is installed on the plug seat by the threads engaging with the pipe thread.

[0012] The beneficial effects of adopting the above-mentioned further solutions are:

[0013] The interlocking of the threaded wires and pipe threads provides a very robust connection. This connection method can resist forces and vibrations from all directions, ensuring that the retaining ring is stably positioned on the connector and is not easily loosened or dislodged.

[0014] Furthermore, the limiting ring moves up and down on the connector through the interaction of the threads and pipe threads, thereby blocking the sleeve and preventing it from being accidentally triggered, thus ensuring that the sleeve blocks and limits the positioning bead.

[0015] The beneficial effects of adopting the above-mentioned further solutions are:

[0016] Through the precise fit of the threaded and pipe threads, the retaining ring can be accurately adjusted in height on the connector. This adjustment method ensures that the retaining ring accurately blocks the sleeve, effectively preventing accidental triggering of the sleeve. The threaded and pipe thread connection provides high stability and can resist external impacts and vibrations. Therefore, the retaining ring maintains a stable position when blocking the sleeve, and is not prone to loosening or falling off. The retaining ring's blocking action effectively prevents the sleeve from being accidentally triggered during bag use. This design avoids safety issues such as bag wheels loosening or falling off due to misoperation of the sleeve.

[0017] Furthermore, the socket has an internal cavity for receiving, and a positioning bead is movably installed in the cavity. After the connector is inserted into the socket, it is engaged with the positioning bead and the slot to connect and fix the socket and the connector.

[0018] The beneficial effects of adopting the above-mentioned further solutions are:

[0019] This design allows for a quick and secure connection between the connector and the socket. Once the connector is inserted into the socket, a locating bead engages with a slot on the connector, securing the connection. This connection method is not only fast but also robust and resistant to loosening.

[0020] Furthermore, after the positioning bead is inserted into the slot, the positioning bead is blocked by the sleeve.

[0021] The beneficial effects of adopting the above-mentioned further solutions are:

[0022] After the positioning bead is inserted into the slot, the sleeve prevents it from accidentally dislodging due to external factors such as vibration or impact. This design ensures a more secure connection between the connector and the socket, reducing the likelihood of loosening and improving the overall stability of the luggage wheels. The sleeve's blocking effect also means that the connector will not easily detach due to external forces during normal use. This is crucial for user safety, especially during walking or movement; a stable wheel connection prevents the luggage from accidentally falling off or tipping over, avoiding potential dangers.

[0023] Furthermore, a groove is provided at the bottom end of the sleeve. When the connector and the socket need to be separated, by pushing the sleeve, the sleeve compresses the spring, and the groove of the sleeve moves to the receiving cavity of the socket. At this time, pulling the connector pushes the positioning bead back into the receiving cavity and the groove, thereby facilitating the separation operation of the connector and the socket.

[0024] The beneficial effects of adopting the above-mentioned further solutions are:

[0025] This design allows users to easily separate the connector from the socket with a simple push and pull motion, without the need for additional tools or complicated procedures. This greatly improves user convenience, especially in emergencies or when quick replacement of bag wheels is required. By creating a groove at the bottom of the sleeve that mates with the receiving cavity of the socket, the design achieves a compact structure without compromising connection stability. This compact structure helps save space, making bags lighter and more aesthetically pleasing. The design simplifies the separation process of the connector from the socket, thus reducing maintenance difficulty. Users can easily replace, repair, or clean bag wheels without worrying about complicated disassembly processes.

[0026] This utility model provides a bag with detachable wheels. It has the following advantages:

[0027] The pulley module can be easily connected to or separated from the housing through the plug-in assembly of the connector and socket, and the locking of the positioning bead and slot. This design not only simplifies the installation and disassembly process but also improves operational convenience. The grooved design of the sleeve allows the spring to be compressed by pushing the sleeve when it is necessary to separate the connector and socket, thereby causing the positioning bead to retract into the receiving cavity and groove, thus facilitating separation. This design is not only ingenious but also practical.

[0028] The lifting design of the limit ring effectively prevents the sleeve from being accidentally triggered, thus avoiding the loosening or detachment of the pulley module due to accidental movement of the sleeve during bag use. This design improves the safety of bag use.

[0029] Once the pulley module is installed, the engagement between the limit ring and the pipe thread on the connector, along with the blocking effect of the sleeve on the positioning ball, ensures the stability of the pulley module during the use of the luggage, preventing the luggage from becoming uncontrollable or damaged due to loose pulleys.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0038] Please see Figures 1 to 3 As shown, the embodiments provided by this utility model are as follows: Example 1

[0039] A bag with detachable wheels includes a bag body 4, a pull rod 3 mounted on the top of the bag body 4, a handle 2 mounted on the top of the pull rod 3, a handle 1 mounted on one side of the bag body 4, and a mounting base 6 mounted on the bottom of the bag body 4. A pulley module 5 is mounted on the bag body 4 via the mounting base 6. The pulley module 5 has a connector 506 and a fixing frame 501. A connector 502 is located at the top of the fixing frame 501, and the fixing frame 501 connects to the connector 506 via the connector 502. 06. Plug-in assembly: The plug-in base 506 is connected and fixed to the mounting base 6. The outer side of the plug-in base 506 is provided with a pipe thread 507. A limiting ring 504 is installed on the outer side of the plug-in base 506 through the pipe thread 507. The inner side of the limiting ring 504 is provided with a thread 505. The limiting ring 504 is installed on the plug-in base 506 through the mutual engagement of the thread 505 and the pipe thread 507. The mutual engagement of the thread 505 and the pipe thread 507 provides a very stable connection method. This connection method can resist forces and vibrations from all directions, ensuring the stable position of the limiting ring 504 on the connector 506, preventing it from loosening or falling off. The limiting ring 504 moves up and down on the connector 506 through the interaction of the thread 505 and the pipe thread 507, thereby blocking the sleeve 503 and preventing it from being accidentally triggered. This ensures that the sleeve 503 blocks and limits the positioning bead 513. Through the precise engagement of the thread 505 and the pipe thread 507, the limiting ring 504 can achieve precise up and down adjustment on the connector 506. This adjustment method ensures that the limiting ring 504 accurately blocks the sleeve 503, effectively preventing the sleeve 503 from being accidentally triggered. The connection method of the thread 505 and the pipe thread 507 has high stability and can resist external impacts and vibrations. Therefore, the limiting ring 504 can maintain a stable position when blocking the sleeve 503, preventing it from loosening or falling off. The limiting ring 504 effectively prevents the sleeve 503 from being accidentally triggered during the use of the bag. This design avoids safety issues such as loosening or falling off of the bag wheels due to misoperation of the sleeve 503. The sleeve 503 is installed on the outside of the connector 506. Example 2

[0040] To facilitate the separation of the connector 502 from the socket 506, for example, as shown... Figures 1 to 3 As shown, the present invention further includes: a roller 509 rotatably mounted on a fixing frame 501; a slot 508 formed on a plug connector 502; a receiving cavity 511 formed inside a plug base 506; a positioning bead 513 movably mounted in the receiving cavity 511; after the plug connector 502 is inserted into the plug base 506, it is engaged with the slot 508 by the positioning bead 513, thereby connecting and fixing the plug base 506 and the plug connector 502. This design allows for a quick and stable connection between the plug connector 502 and the plug base 506. Once the plug connector 502 is inserted into the plug base 506, the positioning bead 513 will engage with the slot 508 on the plug connector 502, thereby achieving a fixed connection between the two. This connection method is not only fast but also secure and not easily loosened. After the positioning bead 513 is inserted into the slot 508, it is blocked by the sleeve 503. This effectively prevents the positioning bead 513 from accidentally coming out of the slot 508 due to external factors (such as vibration, impact, etc.). This design ensures a more secure connection between the connector 502 and the connector base 506, making it less prone to loosening and thus improving the overall stability of the luggage wheels. The blocking effect of the sleeve 503 on the positioning bead 513 also means that the connector 502 will not easily fall off due to external forces during normal use. This is crucial for ensuring user safety, especially during walking or movement. A stable connection between the bag wheels prevents the bag from accidentally falling off or tipping over, avoiding potential dangers. The bottom end of the sleeve 503 has a groove 512. When the connector 502 needs to be separated from the connector base 506, pushing the sleeve 503 compresses the spring 510, moving the groove 512 of the sleeve 503 to the receiving cavity 511 of the connector base 506. At this point, pulling the connector 502 pushes the positioning bead 513 back into the receiving cavity 511 and the groove 512, facilitating the separation of the connector 502 from the connector base 506. This design allows users to separate the connector 502 from the connector base 506 with simple pushing and pulling actions, without the need for additional tools or complicated procedures. This greatly improves the convenience of user operation, especially in emergencies or when quick replacement of bag wheels is required. By creating a groove 512 at the bottom of the sleeve 503 that mates with the receiving cavity 511 of the connector 506, this design achieves a compact structure without compromising connection stability. This compact structure helps save space, making the bag lighter and more aesthetically pleasing. The design also simplifies the separation process of the connector 502 from the connector 506, reducing maintenance difficulty. Users can easily replace, repair, or clean the bag wheels without worrying about complicated disassembly processes.

[0041] Working principle:

[0042] The pulley module 5 is connected to the plug-in seat 506 on the mounting base 6 at the bottom of the housing 4 via its fixed bracket 501 and plug-in connector 502. The plug-in connector 502 can be smoothly inserted into the plug-in seat 506. When the plug-in connector 502 is inserted into the plug-in seat 506, the positioning bead 513 inside the plug-in seat 506 is squeezed by the plug-in connector 502 and moves along its path. Once the slot 508 on the plug-in connector 502 is aligned with the path of the positioning bead 513, the sleeve 503 will block the positioning bead 513 inserted into the slot 508 under the action of the spring 510, thereby achieving a fixed connection between the plug-in connector 502 and the plug-in seat 506. A limit ring 504 is installed on the outside of the plug-in seat 506 through the pipe thread 507. The inner side of the limit ring 504 has threads 505 that mesh with the pipe thread 507. By rotating the limit ring 504, it can be raised and lowered on the plug-in seat 506. When the limit ring 504 descends to a certain position, it will block the sleeve 503 (the sleeve 503 is installed on the fixing bracket 501 and is used to prevent the positioning bead 513 from popping out), thereby ensuring the stability of the positioning bead 513 in the slot 508.

[0043] When it is necessary to separate the pulley module 5 from the housing 4, the sleeve 503 is first moved by pushing it to overcome the elastic force of the spring 510. The bottom end of the sleeve 503 has a groove 512. When the sleeve 503 moves to a certain position, the groove 512 aligns with the receiving cavity 511 of the connector 506. After the groove 512 of the sleeve 503 aligns with the receiving cavity 511, pulling the connector 502 will cause the positioning bead 513 to retract into the receiving cavity 511 under the pressure of the connector 502, and simultaneously enter the groove 512.

[0044] In this way, the positioning bead 513 no longer locks the connector 502, allowing the connector 502 to be smoothly pulled out of the connector socket 506. Continue pulling the connector 502 until it is completely separated from the connector socket 506. At this point, the connection between the roller 509 and the housing 4 is broken, allowing for replacement or maintenance operations.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
