Technical Field

[0001] This utility model relates to the field of bag accessories technology, specifically a detachable bag wheel. Background Technology

[0002] Traditional luggage wheels are usually fixed to the bottom of the luggage, and they are prone to wear or damage during use. For example, when the luggage travels over uneven ground, the wheels are subjected to impact and friction, leading to wear and necessitating wheel removal and replacement. A search revealed Chinese patent publication number CN221678424U, which discloses a detachable luggage wheel, including a mounting plate and a swivel wheel fixing mechanism. The mounting plate has multiple sets of bolt holes, and the bottom of the mounting plate has an installation and removal mechanism. This mechanism works in conjunction with the swivel wheel fixing mechanism to allow for the installation and removal of the wheels.

[0003] While the above-mentioned technical solutions enable quick replacement and repair of bag wheels, and improve the ease of use and durability of bag wheels, the operation is cumbersome because it requires pulling the buckle and pressing the limiting piece inward to remove the caster when disassembling and installing the wheel mounting parts. Furthermore, the pulley mounting plate used to install the wheel is fixedly connected to the mounting parts, and the whole assembly needs to be replaced when damaged, which increases maintenance costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detachable bag wheel, comprising an mounting plate for mounting on the outer surface of the bag, a fixing plate fixedly connected to the lower surface of the mounting plate, the bottom of the fixing plate being hollow, a boss inserted into the bottom of the fixing plate, a snap-fit ​​mechanism cooperating with the boss being installed inside the fixing plate, a release mechanism cooperating with the snap-fit ​​mechanism being installed on the outer surface of the fixing plate, a vertical shaft rotatably connected to the bottom of the boss, a connecting plate fixedly connected to the bottom end of the vertical shaft, side plates fixedly connected to both sides of the connecting plate, and a movable wheel rotatably mounted between the two side plates;

[0006] The locking mechanism includes a ring array of J-shaped locking plates that are slidably connected around the outer surface of the fixed plate. The top of the boss has a groove, and the inside of the groove has a slot that matches the J-shaped locking plate. A protrusion is fixedly connected to the inner bottom of the fixed plate, and a spring is fixedly connected between the outer surface of the protrusion and the J-shaped locking plate.

[0007] Preferably, the top of the boss is rectangular, and the bottom of the fixing plate is slidably connected to the top of the boss, which can limit the boss after it is installed and increase its stability.

[0008] Preferably, the release mechanism includes an annular frame rotatably connected to the outer surface of the fixed plate. An annular groove is provided inside the annular frame. Multiple wedge blocks that cooperate with the J-shaped clamping plates are fixedly connected in an annular array inside the annular groove. Rotating the annular frame can drive the wedge blocks to rotate, thereby squeezing each J-shaped clamping plate and realizing the disassembly of the boss.

[0009] Preferably, the outer surface of the side plate is symmetrically connected by two screws through it, and the side plate is fixedly connected to the connecting plate by the screws. The side plate connected by screws is easy to disassemble and replace.

[0010] Preferably, a bolt is used to fix the two side plates through them, and the movable wheel is rotatably connected to the bolt via a bearing. The movable wheel connected by the bolt is easy to disassemble and replace.

[0011] Preferably, the upper surface of the mounting plate has multiple sets of mounting holes to facilitate mounting the mounting plate on the bag.

[0012] This utility model provides a detachable bag wheel. It has the following advantages:

[0013] 1. This detachable bag wheel, through its locking and releasing mechanisms, allows for easy removal of the fixed plate by simply rotating the annular frame to rotate multiple wedge blocks, which in turn squeezes the J-shaped locking plate, causing one end of the J-shaped locking plate to move out of the slot, thus allowing the protrusion to be removed. The operation is simple and requires no complicated procedures, thereby solving the problem of cumbersome operation caused by existing bag wheels requiring both pulling the buckle and pressing the limiting piece inward to remove the caster when disassembling the installation parts.

[0014] 2. This type of detachable bag wheel has two side plates fixed to the connecting plate with screws. While ensuring its structural strength, it also allows for the disassembly and replacement of the corresponding side plates according to specific circumstances, thereby solving the problem of increased cost for replacing the wheel mounting frame of the existing device, which is an integrated structure.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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. Example

[0024] like Figures 1 to 7 As shown, a detachable bag wheel includes a mounting plate 1 for mounting on the outer surface of the bag. The upper surface of the mounting plate 1 has multiple sets of mounting holes 16. A fixing plate 2 is fixedly connected to the lower surface of the mounting plate 1. The bottom of the fixing plate 2 is hollow, and a boss 3 is inserted into the bottom of the fixing plate 2. A locking mechanism that mates with the boss 3 is installed inside the fixing plate 2. A releasing mechanism that mates with the locking mechanism is installed on the outer surface of the fixing plate 2. A vertical shaft 4 is rotatably connected to the bottom of the boss 3. A connecting plate 5 is fixedly connected to the bottom end of the vertical shaft 4. Side plates 6 are fixedly connected to both sides of the connecting plate 5, and a movable wheel 7 is rotatably mounted between the two side plates 6.

[0025] The locking mechanism includes a ring array of J-shaped locking plates 8 that slide through the outer surface of the fixed plate 2. A groove is formed on the top of the boss 3, and a slot 9, which mates with the J-shaped locking plates 8, is formed inside the groove. A protrusion 10 is fixedly connected to the inner bottom of the fixed plate 2, and a spring 11 is fixedly connected between the outer surface of the protrusion 10 and the J-shaped locking plates 8. The top of the boss 3 is rectangular, and the bottom of the fixed plate 2 is slidably connected to the top of the boss 3. When installing the protrusion 10, simply insert the top of the protrusion 10 into the bottom of the fixed plate 2; under the action of the spring 11, one end of the J-shaped locking plate 8 will automatically engage in the slot 9, facilitating quick and easy installation of the protrusion 10.

[0026] The release mechanism includes an annular frame 12 rotatably connected to the outer surface of the fixed plate 2. An annular groove is formed inside the annular frame 12, and multiple wedge-shaped blocks 13, which cooperate with the J-shaped locking plate 8, are fixedly connected in a circular array inside the groove. When it is necessary to remove the protrusion 10, simply rotate the annular frame 12. The rotation of the annular frame 12 will cause the multiple wedge-shaped blocks 13 to rotate, which will press against the J-shaped locking plate 8, causing one end of the J-shaped locking plate 8 to move out of the locking groove 9. At this point, the protrusion 10 can be removed. The operation is simple and requires no complicated procedures, thus solving the problem of cumbersome operation caused by the need to pull the buckle and press the limiting piece inward to remove the caster when disassembling and installing existing bag wheels.

[0027] Two screws 14 are symmetrically and rotatably connected to the outer surface of the side plate 6, and the side plate 6 is fixedly connected to the connecting plate 5 by the screws 14.

While ensuring its structural strength, the corresponding side plate 6 can also be disassembled and replaced according to specific conditions, thereby solving the problem of increased cost for replacing the existing device wheel mounting frame, which is an integrated structure.

[0028] A bolt 15 is fixedly connected between the two side plates 6, and the movable wheel 7 is rotatably connected to the bolt 15 via a bearing. The bolt 15 facilitates the installation and removal of the movable wheel 7.

[0029] Working principle: The top of the boss 3 is rectangular, and the bottom of the fixing plate 2 is slidably connected to the top of the boss 3. When installing the protrusion 10, simply insert the top of the protrusion 10 into the bottom of the fixing plate 2. Under the action of the spring 11, one end of the J-shaped locking plate 8 will automatically engage in the slot 9, facilitating quick and easy installation of the protrusion 10. When it is necessary to remove the protrusion 10, simply rotate the annular frame 12. The rotation of the annular frame 12 will cause multiple wedge blocks 13 to rotate. The rotation of the wedge blocks 13 will squeeze the J-shaped locking plate 8, causing one end of the J-shaped locking plate 8 to move out of the slot 9. At this point, the protrusion 10 can be removed. The operation is simple and requires no complicated procedures, thus solving the problem of cumbersome operation caused by the need to pull the buckle and press the limiting piece inward when disassembling and installing the existing bag wheels.

[0030] Both side plates 6 are fixed to the connecting plate 5 by screws 14. While ensuring its structural strength, the corresponding side plates 6 can be disassembled and replaced according to specific circumstances, thereby solving the problem of the existing device wheel mounting frame being an integrated structure and increasing the cost of replacement. Bolts 15 facilitate the installation and removal of the movable wheel 7.
