Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and more specifically to a handheld adhesive roller. Background Technology

[0002] Sticky rollers, also known as adhesive rollers or cleaning rollers, are cleaning tools specifically designed to remove surface dust, hair, fibers, and other tiny particles. They are widely used in electronics manufacturing, printing, photography, laboratories, and home cleaning, and are particularly suitable for cleaning fine particles and electrostatically attracted impurities that are difficult to remove using traditional methods.

[0003] In existing adhesive rollers, the cleaning cylinder and the connecting cylinder are detachably connected, which facilitates the replacement of the cleaning cylinder. However, in existing adhesive rollers, the cleaning cylinder and the connecting cylinder are directly and tightly connected. Although this connection method has high stability, it makes the assembly of the cleaning cylinder and the connecting cylinder difficult and cumbersome. Summary of the Invention

[0004] The first objective of this invention is to address the aforementioned problems in the existing technology by providing a handheld adhesive roller that is easy to load and unload and has a compact structure.

[0005] The second objective of this invention is to provide a storage box for the aforementioned handheld adhesive roller.

[0006] To achieve the first objective mentioned above, this utility model can be implemented through the following technical solutions:

[0007] A handheld adhesive roller includes a handle, a shaft frame, and a cylindrical connecting cylinder. The connecting cylinder is connected to the upper end of the shaft frame, and the handle is connected to the lower end of the shaft frame. The roller further includes a pressure cylinder and a spring. The connecting cylinder has a through hole on its side, and a sheet-like, elastic pressure plate is located at the through hole. The upper end of the shaft frame has a transversely arranged connecting section, which is coaxially aligned with and fixedly connected to the connecting cylinder. The pressure cylinder is located inside the connecting cylinder and is sleeved on the connecting section. The two ends of the spring act on the pressure cylinder and the connecting cylinder, respectively. A contact assembly is provided between the pressure cylinder and the pressure plate. Initially, under the elastic force of the spring, the contact assembly is in a separated state, with the outer side of the pressure plate extending outwards from the connecting cylinder. When an external force is applied to move the pressure cylinder, the contact assembly can be in a connected state, and the outer side of the pressure plate can retract into the connecting cylinder.

[0008] In the aforementioned handheld adhesive roller, the through hole is a strip-shaped hole, the pressure plate is located inside the through hole and one end of the pressure plate is fixedly connected to the connecting cylinder, and there are gaps between the other end of the pressure plate and both sides of the pressure plate and the through hole wall of the connecting cylinder.

[0009] In the aforementioned handheld adhesive roller, the pressing plate and the connecting cylinder are an integral structure.

[0010] In the aforementioned handheld adhesive roller, the connecting cylinder includes an upper shell with an internal cavity and an open bottom, and a lower shell with an internal cavity and an open top. The upper shell and the lower shell are connected to form a cylindrical connecting cylinder.

[0011] The aforementioned handheld adhesive roller also includes a positioning cylinder located inside the connecting cylinder. The outer diameter of the positioning cylinder matches the inner diameter of the connecting cylinder. The connecting section is inserted and connected to the positioning cylinder, and the two ends of the spring act on the positioning cylinder and the pressure cylinder ends, respectively.

[0012] In the aforementioned handheld adhesive roller, the end of the pressure cylinder has a protruding guide section, the outer diameter of which matches the inner diameter of the connecting cylinder, and the spring is sleeved on the connecting section with its two ends acting on the positioning cylinder and the guide section respectively.

[0013] In the aforementioned handheld adhesive roller, the contact assembly includes a first contact piece protruding from the inner side of the pressure plate and a second contact piece protruding from the outer side of the pressure cylinder. Under the elastic force of the spring, the first contact piece tends to move away from the second contact piece. When an external force is applied to push the pressure cylinder, the second contact piece can push the first contact piece and cause the pressure plate to retract into the side of the connecting cylinder.

[0014] In the aforementioned handheld adhesive roller, the end of the connecting cylinder has a through positioning hole, and the end of the pressure cylinder has a protruding button. The button is embedded in the positioning hole, and under the elastic force of the spring, the button tends to extend out of the end of the connecting cylinder.

[0015] In the aforementioned handheld adhesive roller, one end of the contact piece has an inclined contact surface one, and the other end of the contact piece has an inclined contact surface two. During the gradual contact between the second contact surface and the first contact surface, the pressure plate can gradually retract into the connecting cylinder.

[0016] In the aforementioned handheld adhesive roller, the outer side of the pressure plate has several protruding ribs along its length.

[0017] To achieve the second objective mentioned above, this utility model can be implemented through the following technical solutions:

[0018] This storage box includes a box body with an internal cavity and an open top, a connecting tube that can be inserted into the box body and a handle located on the outside of the box body.

[0019] Compared with existing technologies, the pressure plate of this handheld sticky roller extends out of the connecting cylinder in the initial state. Therefore, after the cleaning cylinder is fitted onto the connecting cylinder, the connection stability between the cleaning cylinder and the connecting cylinder can be effectively guaranteed.

[0020] Conversely, when an external force is applied to press the cylinder, the pressure plate retracts into the connecting cylinder under the aforementioned external force. At this time, the cleaning cylinder can be easily and stably fitted onto the connecting cylinder. It can be seen that this handheld adhesive roller makes it easy to load and unload the cleaning cylinder.

[0021] Meanwhile, the pressure cylinder and contact components are all located inside the connecting cylinder, so the entire handheld sticky roller structure is relatively compact and has high practical value. Attached Figure Description

[0031] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0032] like Figure 1-7 As shown, this handheld adhesive roller includes a handle 1, a shaft frame 2, and a cylindrical connecting tube 3. The connecting tube 3 is connected to the upper end of the shaft frame 2, and the handle 1 is connected to the lower end of the shaft frame 2.

[0033] It also includes a pressure cylinder 4 and a spring 5. The side of the connecting cylinder 3 has a through hole 3c, and the through hole 3c has a sheet-like and elastic pressure plate 3d. The upper end of the shaft frame 2 has a horizontally arranged connecting section 2a.

[0034] The connecting section 2a is in the shape of a straight rod.

[0035] The connecting section 2a and the connecting cylinder 3 are coaxially aligned and fixedly connected. The pressure cylinder 4 is located inside the connecting cylinder 3 and is sleeved on the connecting section 2a. The two ends of the spring 5 act on the pressure cylinder 4 and the connecting cylinder 3 respectively. There is a contact assembly between the pressure cylinder 4 and the pressure plate 3d. In the initial state, the contact assembly is in a separated state under the elastic force of the spring 5. At this time, the outer side of the pressure plate 3d extends out of the connecting cylinder 3. When an external force is applied to push the pressure cylinder 4 to move, the contact assembly can be in a connected state and the outer side of the pressure plate 3d can retract into the connecting cylinder 3.

[0036] Initially, the contact assembly is in a separated state under the elastic force of spring 5. At this time, the outer side of the pressure plate 3d extends stably outward from the outer side of the connecting cylinder 3, and the cleaning cylinder 9 located outside the connecting cylinder 3 is squeezed by the pressure plate 3d, which enables the cleaning cylinder 9 and the connecting cylinder 3 to have good connection stability.

[0037] Conversely, when an external force is applied to push the compression cylinder 4, the contact assembly is in a connected state. At this time, the pressure plate 3d is retracted into the connecting cylinder 3 under the aforementioned external force. The cleaning cylinder 9 located on the connecting cylinder 3 can be easily disassembled, and a new cleaning cylinder 9 can also be easily and smoothly installed into the connecting cylinder 3.

[0038] In this embodiment, the cleaning tube 9 is a paper tube.

[0039] As can be seen, when using the handheld adhesive roller, the operator simply holds the handle 1. During the cleaning operation, the cleaning cylinder 9 connected to the connecting cylinder 3 is responsible for the main cleaning work, and the cleaning cylinder 9 can be easily and quickly replaced after a long period of operation.

[0040] The through hole 3c is a strip-shaped hole. The pressure plate 3d is located inside the through hole 3c and one end of the pressure plate 3d is fixedly connected to the connecting cylinder 3. There are gaps between the other end of the pressure plate 3d and both sides of the pressure plate 3d and the hole wall of the through hole 3c of the connecting cylinder 3.

[0041] The tablet 3d and the connecting cylinder 3 are an integral structure.

[0042] This structure allows one end of the tablet 3d to be connected to the wall of the through hole 3c. Since the entire connecting cylinder 3 is made of plastic, the above structure also gives the tablet 3d appropriate elasticity.

[0043] The connecting cylinder 3 includes an upper shell 3a with an internal cavity and an opening at the bottom, and a lower shell 3b with an internal cavity and an opening at the top. The upper shell 3a and the lower shell 3b are connected to form a cylindrical connecting cylinder 3.

[0044] This structure allows for easy insertion of components such as the pressure cylinder 4 and spring 5 into the connecting cylinder 3.

[0045] It also includes a positioning cylinder 6 located inside the connecting cylinder 3. The outer diameter of the positioning cylinder 6 matches the inner diameter of the connecting cylinder 3. The connecting section 2a is inserted and connected to the positioning cylinder 6. The two ends of the spring 5 act on the positioning cylinder 6 and the end of the pressure cylinder 4, respectively.

[0046] Since the positioning cylinder 6 matches the connecting cylinder 3, the positioning cylinder 6 is stably connected inside the connecting cylinder 3. The positioning cylinder 6 provides sufficient space for the connecting segment 2a to connect, that is, there is a relatively large contact area between the connecting segment 2a and the positioning cylinder 6, which ultimately ensures the connection stability at the connection point.

[0047] The pressure cylinder 4 has a protruding guide section 4a at its end. The outer diameter of the guide section 4a matches the inner diameter of the connecting cylinder 3. The spring 5 is sleeved on the connecting section 2a, and the two ends of the spring 5 act on the positioning cylinder 6 and the guide section 4a respectively.

[0048] The guide section 4a enables the pressure cylinder 4 to move smoothly within the connecting cylinder 3.

[0049] At the same time, in the initial state, the guide section 4a holds the tablet 3d in place to prevent the tablet 3d from deforming inward.

[0050] The contact assembly includes a contact piece 3d1 protruding from the inner side of the pressure plate 3d and a contact piece 4b protruding from the outer side of the pressure cylinder 4. Under the elastic force of the spring 5, the contact piece 3d1 tends to move away from the contact piece 4b. When an external force is applied to push the pressure cylinder 4, the contact piece 4b can push the contact piece 3d1 and cause the pressure plate 3d to retract into the side of the connecting cylinder 3.

[0051] After the pressure cylinder 4 is translated under the action of external force, the second contact piece 4b located on it also moves until the second contact piece 4b contacts the first contact piece 3d1. The first contact piece 3d1 is pushed, and the entire pressure piece 3d retracts into the connecting cylinder 3.

[0052] The end of the connecting cylinder 3 has a through positioning hole 3e, and the end of the pressure cylinder 4 has a protruding button 4c. The button 4c is embedded in the positioning hole 3e, and under the elastic force of the spring 5, the button 4c tends to extend out of the end of the connecting cylinder 3.

[0053] This structure serves two purposes:

[0054] Firstly, since button 4c is always located at positioning hole 3e, pressure cylinder 4 will not rotate relative to connecting cylinder 3;

[0055] Secondly, button 4c is located in a fixed position, making it easy for operators to apply external force to push and squeeze cylinder 4.

[0056] The end of the first contact piece 3d1 has an inclined contact surface 3d11, and the end of the second contact piece 4b has an inclined contact surface 4b1. During the gradual contact between the second contact surface 4b1 and the first contact surface 3d11, the pressure plate 3d can gradually retract into the connecting cylinder 3.

[0057] Since both contact surface 3d11 and contact surface 4b1 are inclined surfaces, and their inclination directions are the same, contact surface 4b1 and contact surface 3d11 can gradually come into contact, and the tablet 3d can also gradually retract into the connecting cylinder 3.

[0058] The outer side of the compression plate 3d has several protruding ribs 7 along its length.

[0059] The ribs 7 increase the frictional resistance between the tablet 3d and the cleaning cylinder 9, ultimately ensuring that the cleaning cylinder 9 can be stably connected to the connecting cylinder 3.

[0060] This storage box includes a box body 8 with an internal cavity and an open top, a connecting tube 3 that can be embedded in the box body 8 and a handle 1 located outside the box body 8.

[0061] When not in use, the connecting tube 3 is embedded in the box 8 to prevent the connecting tube 3 from being contaminated by the outside.

[0062] In its initial state, the pressure plate of this handheld adhesive roller extends beyond the connecting cylinder. Therefore, after the cleaning cylinder is fitted onto the connecting cylinder, the connection stability between the cleaning cylinder and the connecting cylinder can be effectively guaranteed.

[0063] Conversely, when an external force is applied to press the cylinder, the pressure plate retracts into the connecting cylinder under the aforementioned external force. At this time, the cleaning cylinder can be easily and stably fitted onto the connecting cylinder. It can be seen that this handheld adhesive roller makes it easy to load and unload the cleaning cylinder.

[0064] Meanwhile, the pressure cylinder and contact components are all located inside the connecting cylinder, so the entire handheld sticky roller structure is relatively compact and has high practical value.

[0065] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.

[0066] The technical solutions in the above embodiments have clearly and completely described the content of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
