Technical Field
[0001] This utility model relates to the field of daily necessities technology, specifically to a lint roller that allows for easy replacement of the lint roller. Background Technology
[0002] A lint roller is a tool used to remove fine fibers, hair, debris, and dust from the surfaces of objects such as sofas, sheets, blankets, clothing, carpets, curtains, chairs, and mats. Its structure generally includes a handle, a U-shaped front end connected to the handle, and a paper roll rotating on the U-shaped front end. The paper roll has an adhesive surface, and pushing or pulling the handle causes the paper roll to roll across the surface of the object being linted, thus cleaning it. Existing rollers often require frequent paper roll replacements. However, most existing lint rollers are one-piece structures, requiring the mounting parts on both sides of the bracket to be forcibly pried open during replacement. The paper roll can only be detached from the handle by the elastic deformation of the bracket, or it can only be inserted or removed from the bracket by squeezing and deforming the paper roll. Each disassembly requires considerable force, making the removal and installation of the paper roll very inconvenient. Alternatively, the U-shaped front end bracket may be a detachable structure, but the shaft connecting the rotating paper roll is usually installed inside the U-shaped front end bracket. Replacing the paper roll requires opening the side covers on both sides of the U-shaped front end bracket to remove the shaft and take out the paper roll, making the disassembly process cumbersome. Utility Model Content
[0003] The purpose of this invention is to provide a lint roller that allows for easy replacement of the lint roller without disassembling the lint roller's structure.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A lint roller with easy replacement of the lint roller includes a handle, a U-shaped bracket, and a lint roller. The U-shaped bracket includes a crossbar and side plates on both sides of the crossbar. The two side plates and the crossbar are integrally U-shaped. The handle is connected to the crossbar. The side plates are coaxially provided with shaft holes. At least one side plate has a guide ramp on its inner wall. One end of the guide ramp is connected to the shaft hole, and the other end of the guide ramp is inclined towards the outer wall of the side plate and extends to the edge of the side plate to form a notch. The two ends of the lint roller are detachably provided with connecting seats. The connecting seats are provided with rotating shafts, and at least one rotating shaft is an elastic shaft. By pressing the elastic shaft through the guide ramp, the rotating shaft can be inserted into the shaft hole and the lint roller can be rotated freely, or the rotating shaft can be removed from the shaft hole to replace the lint roller.
[0006] Preferably, the guide ramp extends along the length direction of the side plate or along the width direction of the side plate.

Detailed Implementation
[0023] The present invention will be further described below with reference to the accompanying drawings:
[0024] like Figures 1 to 6 As shown, a lint roller with a convenient replaceable roller includes a handle 1, a U-shaped bracket 2, and a lint roller 9. The U-shaped bracket 2 includes a crossbar 21 and side plates 3 located on both sides of the crossbar. The two side plates 3 and the crossbar 21 are U-shaped as a whole. The handle 1 is connected to the crossbar 21. The lint roller 9 is rotatably connected to the two side plates 3. When in use, hold the handle and push the lint roller 9 to rotate on the item to be cleaned. The sticky layer on the surface of the lint roller 9 will stick and remove the debris or lint on the item to be cleaned. The side plate 3 is provided with a shaft hole 31, and at least one inner wall of the side plate 3 is provided with a guide ramp 34. One end of the guide ramp 34 is connected to the shaft hole 31, and the other end of the guide ramp 34 is inclined towards the outer wall 33 of the side plate and extends to the edge of the side plate 3 to form a notch 35. The two ends of the lint roller 9 are detachably provided with connecting seats 4. The connecting seats 4 are provided with rotating shafts 10, and at least one rotating shaft is an elastic shaft 62. By pressing the elastic shaft 62 through the guide ramp 34, the rotating shaft 10 can be installed into the shaft hole 31 and the lint roller 9 can be rotated freely, or the rotating shaft 10 can be removed from the shaft hole 31 to replace the lint roller 9.
[0025] When the lint roller 9 needs to be replaced, press the elastic shaft 62 to retract it towards the connecting seat 4 to the shaft hole 31, and at the same time pull the lint roller 9 outward so that its end tilts towards the guide slope 34. In this way, the elastic shaft 62 will disengage from the shaft hole 31 and enter the guide slope 34 connected to the shaft hole 31. At this time, the elastic shaft 62 will restore its deformation and push outward towards the connecting seat 4, which will push the elastic shaft 62 to slide along the guide slope 34 to the notch 35. Then the elastic shaft 62 will separate from the side plate 3, making it easy to remove the lint roller 9 from the U-shaped bracket 2. Then remove the connecting seat 4 from both ends of the lint roller 9 to complete the disassembly of the lint roller 9.
[0026] When installing the lint roller, connect the connecting seat 4 to both ends of the lint roller. When one of the shafts is an elastic shaft, first insert the other shaft into the shaft hole 31, and place the elastic shaft at the notch 35. Then press the lint roller along the direction of the guide ramp 34. The guide ramp 34 squeezes and guides the elastic shaft 62 to move towards the shaft hole 31. When the elastic shaft 62 reaches the shaft hole 31, it recovers its deformation and springs into the shaft hole 31. That is, the elastic shaft 62 is fixed in the shaft hole 31 and can rotate in the shaft hole 31, thus completing the installation of the lint roller. Alternatively, when both shafts are elastic shafts, guide ramps 34 are provided on the inner walls of both side plates. The two elastic shafts are placed at the notch 35, and then the middle of the lint roller is pressed along the direction of the guide ramps 34. The guide ramps 34 compress and guide the elastic shafts 62 towards the shaft hole 31. When the elastic shafts 62 reach the shaft hole 31, they recover their deformation and spring into the shaft hole 31. That is, the elastic shafts 62 are fixed in the shaft hole 31 and can rotate within it, completing the installation of the lint roller. The process is simple and easy to operate.
[0027] In one embodiment, the guide ramp 34 extends along the length direction of the side plate 3 or along the width direction of the side plate 3. Preferably, the guide ramp 34 extends along the length direction of the side plate 3, that is, the guide ramp 34 is perpendicular to the crossbar 21. In this way, when installing the lint roller, the crossbar 21 provides a fixed support for pressing the lint roller, which makes it convenient to press with force, while avoiding improper force that could cause the lint roller to come off.
[0028] In one embodiment, the surface of the elastic shaft 62 is arc-shaped. The arc shape facilitates the elastic shaft 62's disengagement from the shaft hole 31 and its sliding into the guide ramp 34, preventing interference or jamming between the elastic shaft 62 and the edge of the shaft hole 31. When the elastic shaft 62 is pressed near the edge of the shaft hole, it can disengage from the shaft hole 31 due to the force of the lint roller 9 tilting towards the guide ramp 34. This avoids having to press the elastic shaft 62 down below the edge of the shaft hole 31 to disengage it, saving effort and making operation convenient.
[0029] In one embodiment, a pressing groove 8 is provided on the outer wall 33 of the side plate, and a shaft hole 31 is provided at the bottom of the pressing groove 8. The pressing groove 8 is a tapered groove with a smaller inner diameter and a larger outer diameter. This reduces the depth of the shaft hole 31, thereby reducing the force required to press the elastic shaft 62. At the same time, the pressing groove 8 with a larger outer diameter and a smaller inner diameter allows the fingers to press the elastic shaft 62 at a comfortable angle, further increasing the comfort and convenience of operation.
[0030] In one embodiment, the width of the guide ramp 34 matches the diameter of the shaft hole 31, and guide walls 36 are formed on both sides of the guide ramp 34 to prevent the elastic shaft 62 from dislodging from the guide ramp.
[0031] In one embodiment, for ease of processing and manufacturing, the side plate 3 includes a body 37 and a clamping plate 38. The crossbar 21, handle 1 and body 37 are integrally formed. The body 37 is provided with a mounting groove that conforms to the shape of the clamping plate 38. The clamping plate 38 is snapped or plugged into the mounting groove. The guide ramp 34 and the pressing groove 8 are provided on the clamping plate 38.
[0032] In one embodiment, the connecting seat 4 includes a housing 41, the outer diameter of the housing sidewall 44 of which matches the inner diameter of the lint roller 9, facilitating a detachable connection between the connecting seat 4 and the lint roller 9. A rotating shaft 10 is mounted on the top cover 42 of the housing. When one rotating shaft 10 is an elastic shaft, the other rotating shaft is fixedly connected to the top cover 42. When the rotating shaft is an elastic shaft 62, a shaft rod 6 and a return spring (not shown in the figures) are provided inside the housing 41. A first through hole 43 is provided in the middle of the top cover 42 of the housing. One end of the shaft rod 6 passes through the first through hole 43 to form the elastic shaft 62. A raised edge 61 is provided circumferentially in the middle of the shaft rod 6. The return spring is sleeved on the shaft rod 6 and is located between the raised edge 61 and the bottom wall 5 of the housing. The return spring pushes the elastic shaft 62 out of the first through hole 43. Pressing the elastic shaft 62 retracts it into the housing 41, and the protruding edge 61 moves downward to compress the return spring. After releasing the elastic shaft 62, the restoring force of the return spring pushes the elastic shaft 62 out of the housing and ejects it. At the same time, the protruding edge 61 prevents the shaft rod 6 from disengaging from the first through hole 43. Furthermore, the edge of the top cover 42 protrudes from the side wall 44 of the housing, inserting the side wall 44 into both ends of the lint roller. The edge of the top cover 42 contacts the edge of the lint roller to prevent the connecting seat 4 from being over-inserted into the lint roller 9 and affecting its use.
[0033] In one embodiment, a positioning groove 51 is provided in the middle of the bottom wall 5 of the housing, and one side of the return spring is disposed in the positioning groove 51. The positioning groove 51 prevents the return spring from bending and deforming during compression, which would affect its use. A second through hole 52 is provided at the bottom of the positioning groove 51, and the other end of the shaft 6 passes through the second through hole 52. In this way, the return spring is completely sleeved on the shaft 6, further preventing the return spring from bending and deforming. At the same time, when the elastic shaft 62 is pressed, the other end of the shaft 6 passes through the second through hole 52, which does not affect the movement stroke of the elastic shaft 62.
[0034] In another embodiment, the bottom wall 5 of the housing has a circumferential retaining edge 53. The outer diameter of the retaining edge 53 matches the inner diameter of the side wall 44 of the housing, and the retaining edge 53 is inserted into and locked into the side wall 44 of the housing. A thread is provided on the outer side of the retaining edge 53, and an internal thread is provided on the inner side of the side wall 44. The bottom wall 5 is screwed onto the side wall 44 of the housing through the engagement of the internal and external threads. In this embodiment, a protruding retaining strip or block is provided on the outer side of the retaining edge 53, and a retaining groove or hole is provided on the inner side of the side wall 44 of the housing to engage with the retaining strip or block. The bottom wall 5 is fixedly connected to the side wall 44 of the housing through the engagement of the retaining strip / block and the retaining groove / hole. Furthermore, after the retaining edge 53 is inserted into the side wall 44 of the housing, the edge of the bottom wall 5 of the housing is flush with the outer surface of the side wall 44 of the housing, preventing the bottom wall 55 from excessively extending into the side wall 44 and affecting the travel of the shaft 6. Meanwhile, the separate design of the bottom wall 5 and the side wall 44 of the housing facilitates the processing and assembly of the connecting seat 4. Furthermore, the side wall 44 and the top cover 42 of the housing are integrally formed.
[0035] In another embodiment, the edge of the first through hole 43 extends inward to form a first positioning edge 45, and the edge of the second through hole 52 extends into the housing 41 to form a second positioning edge 54. The arrangement of the first positioning edge 45 and the second positioning edge 54 makes the movement of the shaft 6 smoother, and prevents the shaft 6 from interfering with the edges of the first through hole 43 and / or the second through hole 52. Furthermore, a reinforcing rib 63 is provided on the side of the protruding edge 61 near the bottom wall 5, which increases the connection strength between the protruding edge 61 and the shaft 6.
[0036] In the above technical solution, when it is necessary to remove the lint roller 9, hold the handle to fix the U-shaped bracket 2, hold one end of the lint roller 9 with the other hand, and press the elastic shaft 62 with your fingers. At the same time, pull the lint roller 9 outward along the direction of the guide slope 34. The elastic shaft 62 is squeezed out of the shaft hole 31 and stuck on the edge of the shaft hole 31. Then, apply a slight outward pulling force to the lint roller 9 so that the elastic shaft 62 is fully inserted into the guide slope 34. At this time, the return spring pushes the elastic shaft 62 outward. The elastic shaft 62 moves along the guide slope 34 to obtain the ejection space. 4. Slide the roller 9 out to the notch 35, so that the elastic shaft 62 is completely separated from the U-shaped bracket 2. Remove the lint roller 9 diagonally upwards so that the shaft at the other end can be disengaged from the shaft hole 31. This makes it easy to remove the lint roller 9 from the U-shaped bracket 2. When it is necessary to install the lint roller 9, insert the connecting seat 4 and fix it at both ends of the lint roller 9. Then place the elastic shaft 62 at the notch 35 and press the lint roller 9 firmly so that the elastic shaft 62 moves along the guide slope 34 and enters the shaft hole 31. This completes the installation of the lint roller 9. The process is simple and easy to operate.
[0037] The embodiments are merely illustrative of the concept and implementation of this utility model and are not intended to limit it. Under the concept of this utility model, the technical solutions without substantial changes are still within the scope of protection.
