Description

Technical Field

[0001] The utility model relates to the technical field of luggage accessories, in particular to a quick-release universal wheel. Background Art

[0002] A caster is a wheel device that can achieve multi-directional free movement on a plane. It usually consists of a wheel, a wheel frame and a rotating mechanism. The wheel can rotate freely 360 degrees in the horizontal direction around the wheel frame, so that the equipment or object equipped with the caster can easily change the direction of movement without being restricted by traditional fixed-direction wheels. Casters are widely used in many fields. In logistics and transportation, carts and pallet trucks with casters can flexibly shuttle between warehouses and transportation channels, facilitating the handling and loading and unloading of goods. On industrial production lines, some small material transportation tools or equipment are also equipped with casters to improve production efficiency and ease of operation.

[0003] The existing universal wheels are fixed with screws, and a screwdriver is needed to disassemble them, which is very troublesome. When the boxes are transported and stacked in the warehouse, the universal wheels need to be disassembled before they can be stacked. Frequent disassembly of the universal wheels greatly reduces work efficiency. Utility Model Content

[0021] The following will be combined with the drawings of the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a quick-release universal wheel, including a box body 1, a quick-release wheel seat 2 is fixedly connected to the bottom of the box body 1, and slide grooves 10 are opened on the left and right sides of the bottom of the quick-release wheel seat 2, a spring piece 4 is fixedly connected to the front side of the quick-release wheel seat 2, and three limit blocks 11 are fixedly connected to the bottom of the rear side of the quick-release wheel seat 2. A fixing part 3 is slidably connected between the two slide grooves 10, and a rotating part 5 is rotatably connected to the bottom of the fixing part 3. Screws 15 are fixedly connected to the front and rear sides of the bottom of the rotating part 5, and a wheel 6 is rotatably connected to the surface of the screw 15. A locking assembly is provided on the right side of the rotating part 5, and the locking assembly is used to lock the wheel 6.

[0023] Specifically, the fixing part 3 presses down the spring piece 4 on the quick-release wheel seat 2, and the fixing part 3 can be pushed into the quick-release wheel seat 2 through the slide groove 10. After the fixing part 3 is pushed into the quick-release wheel seat 2, the spring piece 4 rebounds and is buckled, thereby achieving quick installation. When the universal wheel needs to be removed, the spring piece 4 is pressed down by hand to disengage the spring piece 4 buckled with the fixing part 3. At this time, the fixing part 3 can be quickly removed, and the screw 15 can be quickly removed by turning the screw 15, thereby achieving quick removal of the wheel 6. When the wheel 6 is worn, only the wheel 6 needs to be replaced, and there is no need to replace the entire wheel.

[0024] Reference Figure 3 The locking assembly includes two rotating shafts 16, both of which are fixedly connected to the rotating member 5. The surface of the rotating member 5 on the right is rotatably connected to the foot pedal 7, and the surface of the rotating shaft 16 on the left is rotatably connected to the rotating member 13, and the bottom of the rotating member 13 is fixedly connected to the locking member 14.

[0025] Specifically, by stepping on the pedal 7 and rotating on the rotating shaft 16, the pedal 7 presses against the rotating member 13 and rotates on the rotating shaft 16, so that the locking member 14 and the wheel 6 are tightly fitted, and the wheel 6 is fixed by the friction between the locking member 14 and the wheel 6.

[0026] Reference Figure 1 Four first screw holes 8 are provided at the bottom of the box body 1 .

[0027] Specifically, the first screw hole 8 is used to fix the quick-release wheel seat 2 on the box body 1 .

[0028] Reference Figure 2 Four second screw holes 9 are opened on the top of the quick-release wheel seat 2, and the quick-release wheel seat 2 and the box body 1 are fixedly connected by screws.

[0029] Specifically, the second screw hole 9 corresponds to the first screw hole 8 , and the quick-release wheel base 2 can be fixed to the box body 1 by screws.

[0030] Reference Figure 3 Four third screw holes 12 are opened on the top of the fixing member 3.

[0031] Specifically, the third screw hole 12 on the fixing member 3 can be fixed to the first screw hole 8 on the box body 1 by screws, thereby directly fixing the fixing member 3 on the box body 1.

[0032] Reference Figure 3 , two protrusions are provided on the bottom left side of the foot pedal 7.

[0033] Specifically, the two protrusions on the foot pedal 7 fit tightly with the bend at the bottom of the rotating part 13. When the foot pedal 7 is rotated under force, the protrusions on the foot pedal 7 press against the side surface of the rotating part 13, thereby locking the rotating part 13. At this time, the locking part 14 is forced to fit tightly against the surface of the wheel 6, thereby fixing the wheel 6.

[0034] Reference Figure 2 , the shape of the shrapnel 4 is a triangle.

[0035] Specifically, the triangular spring piece 4 is used to facilitate installation without pressing the spring piece 4 by hand, and the fixing member 3 can be inserted into the quick-release wheel seat 2 by squeezing the fixing member 3 .

[0036] Reference Figure 3 , the locking piece 14 is made of polyurethane.

[0037] Specifically, the locking member 14 made of polyurethane has excellent wear resistance, oil resistance and shock absorption properties, and can effectively absorb the impact during braking and reduce noise.

[0038] Working principle: When in use, the spring piece 4 on the quick-release wheel seat 2 is pressed down by the fixing part 3, and the fixing part 3 can be pushed into the quick-release wheel seat 2 through the slide groove 10. After the fixing part 3 is pushed into the quick-release wheel seat 2, the spring piece 4 rebounds and is buckled, thereby realizing quick installation. When the universal wheel needs to be removed, the spring piece 4 is pressed down by hand to disengage the spring piece 4 buckled by the fixing part 3. At this time, the fixing part 3 can be quickly disassembled, and the screw 15 can be quickly disassembled by turning the screw 15, thereby realizing quick disassembly of the wheel 6. When the wheel 6 needs to be fixed, step on the foot pedal 7. When the foot pedal 7 is rotated under force, the protrusion on the foot pedal 7 presses against the side surface of the rotating part 13, thereby jamming the rotating part 13. At this time, the locking part 14 is forced to fit tightly against the surface of the wheel 6, thereby realizing fixing the wheel 6.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
