Description

Technical Field

[0001] This utility model relates to the field of luggage wheel technology, and more specifically, to a luggage wheel that is easy to disassemble and replace to prevent foreign objects from entering. Background Technology

[0002] Luggage wheels refer to the wheels that can rotate freely 360 degrees and are installed on the bottom of suitcases, travel bags, and handbags. This allows the luggage to move flexibly in different directions, improving the convenience and stability of carrying. Through a special bearing structure (such as ball bearings or bushings), omnidirectional rotation is achieved. Users can easily drag the luggage in any direction without tilting the luggage. This is especially helpful for turning in narrow spaces (such as airports and subways). The materials need to be both lightweight and wear-resistant to adapt to different surfaces.

[0003] Chinese Patent Announcement No. CN222040144U discloses a conveniently foldable swivel wheel for bags. This design utilizes semi-circular grooves on both sides of the swivel wheel to contact the spherical surfaces of two limiting connecting rods. The two limiting connecting rods then enter the semi-circular grooves on both sides of the swivel wheel, thereby securing the swivel wheel with a certain force. The folding and securing method is relatively simple, allowing for flexible folding of the swivel wheel. Furthermore, the swivel wheel can be directly pulled out for reuse after folding, thus facilitating user use and further improving the practicality of the bag swivel wheel.

[0004] During daily use, the casters on a suitcase are the parts that are most easily damaged. If they are damaged and cannot be used, the casters in the above-mentioned solutions, as well as traditional suitcases, are fixed with rivets or screws. This fixing method requires users to use professional tools or send the suitcase to after-sales service for repair, which causes inconvenience in repair.

[0005] Therefore, a new type of anti-foreign object wheel for bags is proposed to address the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-7 A type of easy-to-disassemble and replaceable anti-foreign-object luggage wheel includes a universal wheel 1 and a fixed plate 2. Connecting plates 5 are installed on both sides of the universal wheel 1. A mounting base 6 is fixedly connected to the end of the connecting plate 5 away from the universal wheel 1. A mounting component 3 is provided at the top of the mounting base 6. A cleaning component 4 is provided on the outside of the universal wheel 1. The fixed plate 2 is fixedly installed on the bottom of the luggage. The universal wheel 1 is detachably connected to the fixed plate 2 through the mounting component 3. The mounting component 3 includes a movable block 39 and multiple annularly distributed limiting blocks 37. Multiple inclined surfaces 315 are provided on the outer end of the movable block 39. An inclined surface 314 matching the inclined surface 315 is provided on the outer end of each of the multiple limiting blocks 37. A connecting block 313 is fixedly connected to the outer end of the inclined surface 315. A drive groove 312 is provided on the outer end of the inclined surface 314. The connecting block 313 is slidably connected to the drive groove 312. When the movable block 39 moves up and down, the connecting block 313 drives the limiting block 37 to move laterally through the drive groove 312.

[0034] Compared to traditional fixing methods, the device in this solution allows for quick replacement without the aid of tools. Bearings are installed inside the caster wheel 1, and two connecting plates 5 are mounted on both sides of the caster wheel 1. Mounting seats 6 are fixed to the ends of the two connecting plates 5, and the mounting seats 6 are also mounted on the caster wheel 1. A cleaning component 4 is also installed on the outside of the two connecting plates 5, i.e., on the caster wheel 1. The cleaning component 4 is mainly used to clean the surface of the caster wheel 1 to prevent foreign objects from damaging its surface.

[0035] Mounting assembly 3 is located on the top of mounting base 6, while fixed plate 2 is fixed to the bottom of the bag with bolts or rivets and cannot be removed. When a new caster wheel 1 needs to be installed, simply press mounting assembly 3 down so that movable block 39 moves limit block 37 into housing 31 through the cooperation of connecting block 313 and inclined surface 314. Then, insert the top of housing 31 into slot 7 until limit plate 35 abuts against the bottom of fixed plate 2, and then release mounting assembly 3. The caster wheel 1 can then be installed on fixed plate 2 through mounting assembly 3. This allows users to quickly replace the caster wheel 1 without tools, improving the convenience of maintenance.

[0036] Please see Figures 1-3 The cleaning component 4 includes two clamping plates 41, which are respectively fixed to the outside of two connecting plates 5. A fixing frame 42 is fixedly installed between the two clamping plates 41, and a movable frame 43 is rotatably connected to the outer end of the fixing frame 42.

[0037] A brush 44 is fixedly installed on the inner side of the movable frame 43. The movable frame 43 rotates to make the brush 44 stick to the outer surface of the universal wheel 1 to clean foreign objects on the outer surface.

[0038] In this design, two clamping plates 41 are fixed to the outer sides of two connecting plates 5 respectively. A fixing frame 42 is fixed to the top of the two clamping plates 41, so that the fixing frame 42 is mounted on the outside of the caster wheel 1. A movable frame 43 is rotatably installed at the outer end of the fixing frame 42. The movable frame 43 can rotate on the fixing frame 42. A brush 44 is fixedly installed on the inner side of the movable frame 43. By rotating the movable frame 43, when it is necessary to clean the caster wheel 1, the brush 44 can be rotated downwards so that the brush 44 is in close contact with the surface of the caster wheel 1. When the caster wheel 1 is pushed to rotate, the brush 44 can clean the caster wheel 1. When rolling on a gravel road, the surface of the caster wheel 1 can be cleaned to prevent gravel from adhering to the surface of the caster wheel 1 and causing damage.

[0039] Please see Figures 4-7 The mounting assembly 3 also includes a housing 31 and a drive plate 32. The bottom end of the housing 31 is rotatably connected to the top of the mounting base 6. Four sliding grooves 36 are provided on the outer end of the housing 31. A movable groove 33 is provided on the inner side of the drive plate 32. The movable groove 33 matches the housing 31.

[0040] A slider 34 is fixedly installed inside the movable groove 33. The slider 34 is arranged in a cross shape. The four sides of the slider 34 are slidably connected to the four sliding grooves 36 respectively, and the slider 34 is located inside the housing 31.

[0041] A telescopic spring 310 is installed inside the housing 31. The top of the telescopic spring 310 is connected to the slider 34. A limit plate 35 is fixedly connected to the outer end of the housing 31. The bottom end of the movable block 39 is fixedly connected to the slider 34. Multiple sliding grooves 38 are opened on the outer end of the housing 31. One end of the limit block 37 extends through the sliding groove 38 into the interior of the housing 31.

[0042] Both sides of the limiting block 37 are fixedly connected with side plates 311. The side plates 311 abut against the inner wall of the housing 31. The outer end of the fixing plate 2 is provided with a slot 7. The top of the housing 31 extends through the slot 7 into the interior. One end of the limiting block 37 extends outward and abuts against the bottom of the slot 7 to form a fixation.

[0043] In this design, the bottom of the housing 31 is rotatably mounted on the top of the mounting base 6, allowing the caster wheel 1 to turn when rotating. The interior of the housing 31 is hollow, and four equally spaced sliding grooves 36 are formed around the outer perimeter of the housing 31. At the same time, a movable groove 33 is formed near the center of the outer perimeter of the drive plate 32. The diameter of the movable groove 33 matches that of the housing 31, allowing the movable groove 33 to slide slidably with the outer perimeter of the housing 31. Meanwhile, a slider 34 is fixed inside the movable groove 33. The slider 34 is cross-shaped. When the drive plate 32 is fitted onto the outer perimeter of the housing 31 through the movable groove 33, the four sides of the slider 34 are inserted into the sliding grooves 36, allowing it to slide within the sliding grooves 36.

[0044] Inside the housing 31, a telescopic spring 310 is installed. The top of the telescopic spring 310 is fixedly connected to the slider 34 located inside the housing 31. Thus, the force of the telescopic spring 310 can drive the drive plate 32 to move and then reset. A limiting plate 35 is fixed at the outer end of the housing 31, which divides the housing 31 into upper and lower parts. In the upper part of the housing 31, four equally spaced annular sliding grooves 38 are opened. Four limiting blocks 37 located inside the housing 31 have one end protruding from the sliding grooves 38, making them protrude from the outer surface of the housing 31. Side plates 311 are fixed on both sides of each limiting block 37. Through the obstruction of the side plates 311, when the limiting block 37 extends outward, the side plates 311 abut against the inner wall of the housing 31 to form a limit, restricting the outward extension stroke of the limiting block 37.

[0045] Each limiting block 37 has a first inclined surface 314 on one end inside the housing 31. A movable block 39 is fixed on the top of the slider 34. The movable block 39 is also located inside the housing 31, and four second inclined surfaces 315 are provided on the top of the movable block 39. These second inclined surfaces 315 match the first inclined surfaces 314 on the limiting block 37 and are always in close contact. A drive groove 312 is provided on the first inclined surface 314, and a connecting block 313 is fixed on the second inclined surface 315. When the second inclined surface 315 is in close contact with the first inclined surface 314, the connecting block 313 will slide and connect with the drive groove 312.

[0046] In a static state, the force of the telescopic spring 310 can push the slider 34 upward. At this time, the movable block 39 will also push the four limit blocks 37 upward. The first inclined plane 314 and the second inclined plane 315 abut against each other, pushing one end of the limit block 37 outward. When it is necessary to install the caster wheel 1, the drive plate 32 needs to be pressed down first, so that the slider 34 drives the movable block 39 to move downward. At the same time, the telescopic spring 310 is compressed. At this time, the downward moving movable block 39 will slide inward in the second slide groove 38 through the sliding connection of the connecting block 313 and the drive groove 312. When the limit block 37 extends outward, one end retracts into the housing 31. At this time, the upper part of the housing 31 is inserted into the slot 7 opened on the fixing plate 2 until the limit plate 35 is against the bottom of the fixing plate 2 and cannot be inserted further. Then, the limit plate 35 is released, and the movable block 39 can be pushed upward again by the force of the telescopic spring 310. Then, by pushing the first inclined plane 314 through the second inclined plane 315, the four limit blocks 37 can be pushed outward again, so that the limit blocks 37 are locked in the slot 7, thereby completing the installation. This allows the user to replace the universal wheel 1 by himself, improving the convenience of maintenance.

[0047] Working principle: When using this device to replace a damaged caster wheel 1, the damaged wheel must first be removed. First, press the drive plate 32 downwards, causing the slider 34 to move the movable block 39 downwards, while simultaneously compressing the telescopic spring 310. At this time, the downward-moving movable block 39 will slide inwards within the sliding groove 38 through the sliding connection between the connecting block 313 and the inclined surface 314. The end of the limiting block 37 extending outwards will retract into the housing 31, allowing the damaged wheel to be removed. Then, press the drive plate 32 downwards in the same way, and insert the upper part of the housing 31 into the slot 7 until the limiting plate 35 abuts against the bottom of the fixed plate 2. Finally, release the limiting plate 35, and the force of the telescopic spring 310 will push the movable block 39 upwards again, resetting the limiting block 37 and locking it in the slot 7, thus completing the installation.
