Technical Field

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

[0002] "Bags and bags" is a general term encompassing all kinds of bags used to carry things, including general shopping bags, handbags, clutches, wallets, backpacks, shoulder bags, shoulder bags, waist bags, and various types of rolling suitcases. Since rolling suitcases are currently the most common type of travel bag, "bags and bags" often directly refers to rolling suitcases. Rolling suitcases are equipped with swivel wheels at the bottom, and together with a retractable handle, they allow for easy movement of heavier suitcases, making them popular.

[0003] Most bags have wheels at the bottom for easy movement, but currently the wheels and bags are all one piece, which limits their use and causes great inconvenience. The wheels are also prone to damage and replacement during use, so there is a need for bags with easily detachable wheels. Utility Model Content

[0004] The purpose of this invention is to provide a bag with detachable wheels to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bag with detachable wheels, comprising a bag body, the bottom of which is welded and fixed to a support base, the support base being rotatably connected to the outer side of a rotating shaft, an insertion hole being opened on the outer side of the rotating shaft, an insertion rod being provided on the support base, the outer side of which is welded and fixed to a limiting plate, a spring being sleeved on the outer side of the insertion rod, one end of which is welded and fixed to a pull plate, the outer side of the rotating shaft being welded and fixed to a fixing plate, a slot being opened on the fixing plate, the fixing plate abutting against a mounting plate, a roller being provided on the mounting plate, a moving groove being opened on the mounting plate, a spring being provided inside the moving groove, one end of which is welded and fixed to a locking plate, and the locking plate being welded and fixed to one end of a push plate.

[0006] Preferably, a circular through hole is provided on the side of the support base, and the support base is slidably connected to the outside of the insertion rod through the circular through hole, with one end of the insertion rod being movably inserted into the insertion hole.

[0007] Preferably, one end of the rotating shaft extends into the interior of the support base, and the insertion hole is located inside the support base.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses a fixed plate, a slot, a mounting plate, a moving slot, a spring, a locking plate, and a push plate. By pressing the push plate, the locking plate moves within the moving slot and the slot until the triangular protrusion on the locking plate is moved into the slot. Then, the locking plate can be moved downwards and disengaged from the slot, enabling convenient disassembly of the roller. This effectively reduces the difficulty of disassembling bag rollers, makes it easier for operators to replace bag rollers, and enhances the actual use effect.

[0013] 2. This utility model also incorporates a support base, a rotating shaft, an insertion hole, an insertion rod, a limiting plate, a spring, and a pull plate. By moving the pull plate, the insertion rod is disengaged from the insertion hole. Then, the rotating shaft is rotated so that the roller rotates around the shaft until it is in contact with the bottom surface of the case. This allows for convenient storage of the roller. When the roller is needed, it can be easily removed. This prevents the case from shifting or sliding due to the roller at the bottom during storage. Attached Figure Description

[0019] 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.

[0020] See also Figure 1-4 This utility model provides a technical solution: a bag with detachable wheels, including a bag body 1, the bottom of which is welded and fixed to a support base 2. A through rectangular slot is provided on the support base 2. The support base 2 is rotatably connected to the outer side of a rotating shaft 3. An insertion hole 4 is provided on the outer side of the rotating shaft 3. An insertion rod 5 is provided on the support base 2. The outer side of the insertion rod 5 is welded and fixed to a limiting plate 6. A spring 7 is sleeved on the outer side of the insertion rod 5. One end of the insertion rod 5 is welded and fixed to a pull plate 8. The outer side of the rotating shaft 3 is welded and fixed to a fixing plate 9. A slot 10 is provided on the fixing plate 9. The fixing plate 9 abuts against a mounting plate 11. The mounting plate 11 is rotatably connected to a connecting shaft on the side of a roller 12. A moving groove 13 is provided on the mounting plate 11. One end of a spring 14 is fixedly connected to the inner wall of the moving groove 13. One end of the spring 14 is welded and fixed to a locking plate 15. The locking plate 15 is welded and fixed to one end of a push plate 16.

[0021] A circular through hole is provided on the side of the support base 2. The support base 2 is slidably connected to the outside of the insertion rod 5 through the circular through hole. One end of the insertion rod 5 is movably inserted into the insertion hole 4. There are four support bases 2, which are symmetrically distributed at the bottom of the box body 1. One end of the insertion rod 5 extends to the outside of the support base 2 and is fixedly connected to the pull plate 8. The side of the pull plate 8 is fixedly connected to two symmetrical insertion rods 5. This effectively reduces the number of times the insertion rods 5 are pulled, further improving the efficiency of the rollers 12 in storage and unfolding adjustment.

[0022] One end of the rotating shaft 3 extends into the interior of the support base 2. The insertion hole 4 is located inside the support base 2. The limiting plate 6 is located inside the support base 2. The spring 7 is located between the inner wall of the support base 2 and the limiting plate 6. The insertion holes 4 are located at both ends of the rotating shaft 3. Two insertion holes 4 are opened at each end of the rotating shaft 3. The included angle between the two insertion holes 4 is 90 degrees. In this way, the elasticity of the spring 7 can push the insertion rod 5 into the insertion hole 4. The two insertion holes 4 correspond to the two working states of the roller 12, namely the unfolded and the retracted state, to ensure the stability of the roller 12 in the two working states.

[0023] The movable groove 13 is slidably connected to the outer side of the clamping plate 15. The top of the clamping plate 15 is welded and fixed to the triangular protrusion. The outer side of the movable groove 13 is also slidably connected to the clamping groove 10. The mounting plate 11 is a U-shaped plate. The side of the mounting plate 11 is slidably connected to the outer side of the push plate 16 through a rectangular through groove. Pressing the push plates 16 on both sides causes the clamping plate 15 to move inside the clamping groove 10 and the movable groove 13. While compressing the second spring 14, the triangular protrusion on the side of the clamping plate 15 is completely moved into the clamping groove 10. After that, the mounting plate 11 is moved downward until the clamping plate 15 is disengaged from the clamping groove 10, thus realizing the convenient disassembly of the roller 12.

[0024] Working principle: When in use, the rollers 12 facilitate the movement and handling of the box 1. When placing the box 1, the pull plate 8 is moved outward to disengage the insertion rod 5 from the insertion hole 4, allowing the rollers 12 to rotate and fit against the bottom of the box 1. The support base 2 supports and fixes the entire box 1, preventing the box 1 from slipping due to the rollers 12 during placement. When the rollers 12 need to be disassembled and replaced after long-term use, the push plates 16 on both sides are pressed simultaneously to move the locking plate 15 inside the locking groove 10 and the moving groove 13. While compressing the spring 14, the triangular protrusion on the side of the locking plate 15 is completely moved into the locking groove 10. After that, the mounting plate 11 is moved downward until the locking plate 15 disengages from the locking groove 10, thus achieving convenient disassembly of the rollers 12 and effectively reducing the difficulty of disassembling the rollers 12.
