[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-6A household paper roll that is easy to replace includes a winding frame 1, a limiting convex rail 2 5 is installed on one side of the upper part of the winding frame 1 through a mounting groove 51, a limiting wheel 1 7 is rotatably installed below the limiting convex rail 2 5, and a transmission wheel 8 is rotatably installed on the middle part of the upper end of the winding frame 1, and a clamping claw 3 is rotatably installed on the other side of the frame body, and the inner wall of the clamping claw 3 is correspondingly provided with a limiting convex rail 1 4 and a limiting wheel 2 9, wherein a paper roll 2 is limitedly installed between the winding frame 1 and the clamping claw 3;

[0025] Furthermore, shafts are provided at both ends of the paper winding roller 2, a connecting ring 21 is provided at one end of the shaft, a plurality of through holes are provided on the connecting ring 21, and a limiting groove 22 is provided in the middle of the shaft, which respectively fits with the limiting wheel 1 7 and the limiting wheel 2 9.

[0026] Furthermore, a driving assembly is provided inside the winding frame 1 to drive the transmission wheel 8, and the transmission wheel 8 drives the paper roller 2 to rotate for winding.

[0027] Furthermore, a plurality of springs 1 52 are installed in the middle of the installation slot 51 , and the other end of the spring 1 52 is fixedly connected to the limiting convex rail 2 5 , and the limiting convex rail 2 5 is fitted with the limiting slot 22 .

[0028] Furthermore, a rotation groove 6 is provided on one side of the upper portion of the winding frame 1 , and a clamping claw 3 is rotatably installed in the rotation groove 6 , and the paper roller 2 is clamped and limited by the clamping claw 3 .

[0029] Furthermore, a torsion spring 10 is provided at the rotation connection between the clamping claw 3 and the rotation slot 6 .

[0030] Furthermore, when the paper winding roller 2 is connected to the winding frame 1 , the limiting groove 22 is in squeeze and friction contact with the limiting wheel 1 7 , the transmission wheel 8 , and the limiting wheel 2 9 respectively.

[0031] In this embodiment, the shafts at both ends of the paper winding roller 2 are clamped and installed on the upper part of the winding frame 1, and are limited and clamped by the clamping claws 3. During this process, the shafts at both ends of the paper winding roller 2 are respectively docked and clamped into the clamping claws 3, the limiting cam 1 4, and the limiting cam 2 5 set on the winding frame 1, and are squeezed to allow the paper winding roller 2 to pass through. Then the limiting grooves 22 set at both ends of the paper winding roller 2 are respectively in contact with the clamping claws 3, the limiting wheel 2 9, the limiting wheel 1 7, and the transmission wheel 8 set inside the winding frame 1, and are limited by the wheel bodies.

[0032] At the same time, under the torsion action of the torsion spring 10 , the torsion spring 10 drives the clamping claw 3 to always twist clockwise and limit the limiting groove 22 to ensure the installation stability of the paper roller 2 .

[0033] During the later replacement process, the clamping claws 3 are rotated outward to disengage the limiting wheels 29 from the limiting grooves 22 provided on both sides of the paper winding roller 2. At this time, the connecting rings 21 provided on both sides of the paper winding roller 2 are used to lift the entire paper winding roller 2 and slowly rise to the middle of the winding frame 1. At this time, under the action of the limiting cam 1 4 and the limiting cam 2 5, it can effectively guide and fit with the limiting grooves 22 to ensure the stability of the replacement of the paper winding roller 2.

[0034] Among them, the transmission wheel 8 is driven to rotate through the driving component, and the transmission wheel 8 rotates and squeezes and rubs with the limiting groove 22 to drive the paper roller 2 to rotate. The driving principle and driving parts of the specific transmission wheel 8 not described in detail above are all existing technologies and are common knowledge known to those skilled in the art, and no further explanation is given here.

[0035] Among them, in actual use, the limiting cam 4 set on the clamping claw 3 and the limiting cam 2 5 set on the winding frame 1 are the same structural parts. When the limiting groove 22 is connected to the two, the spring 1 52 inside them is squeezed.

[0036] In the present invention, the paper roll is installed on the winding frame 1, and its limit groove is engaged by the setting of the clamping claw 3. At the same time, the paper roll is limited and driven by the multiple limit wheels and transmission wheel assemblies set on the winding frame 1 and the clamping claw 3, and the paper roll can be automatically locked by the setting of the clamping claw 3 to ensure its installation stability.

[0037] At the same time, by rotating the clamping claw 3 and coordinating with the setting of the limiting convex rail, the convenience of disassembling and replacing the paper roller can be effectively improved, without the need to repeatedly disassemble the bolts, thereby effectively improving the replacement efficiency of the paper roller.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
