Description
Technical Field
[0001] This utility model relates to the field of mop technology, and in particular to a cleanroom-specific mop board with a friction device. Background Technology
[0002] Mops, as common floor cleaning tools, play an important role in people's daily lives. With continuous technological advancements and rising demands for quality of life, higher requirements are being placed on mop performance. Among these, the flexibility and stability of the mop head's rotation have become key considerations. Currently, there are various types of mops on the market, each with a different method of head rotation. Some traditional mops use a simple hinge between the mop head and handle. While this hinge allows the mop head to rotate, this rotation is achieved by pressing the mop head against the ground and applying force to the mop handle. This method is highly dependent on the tightness of the hinge. If the hinge is too loose, the mop head will easily rotate uncontrollably on the handle, making it unusable. If the hinge is too tight, it is difficult to rotate the mop head precisely to the desired angle. Furthermore, with repeated use, the hinged part between the mop head and handle is prone to wear and deformation, rendering the entire mop unusable. Utility Model Content
[0003] To address the aforementioned shortcomings, the purpose of this utility model is to provide a cleanroom-specific mop board with a friction device. By setting a friction ring at the rotating connection between the movable clamp and the connecting round head, the friction ring distributes the rotational force of the movable clamp, making the pressure applied by the screw on the movable clamp more even. This effectively reduces bending and deformation at the connection during use and provides even and precise pressure to the movable clamp, allowing the movable clamp to rotate and be fixed stably, which is beneficial for daily use.
[0004] The technical solution adopted by this utility model to achieve the above objectives is as follows:
[0005] A cleanroom-specific mop with a friction device includes a movable clamp at the lower end of a mop handle and a slide plate hinged to the movable clamp. The lower end of the movable clamp has a downwardly extending first clamp plate and a downwardly extending second clamp plate symmetrical to the first clamp plate. The slide plate has an upwardly extending connecting head inserted between the first and second clamp plates. The mop plate also includes a friction assembly passing through the movable clamp and the connecting head. The friction assembly includes a friction ring embedded in the first clamp plate, an adjusting elastic element with one end pressing against the friction ring, and a screw passing through the adjusting elastic element, the friction ring, the first clamp plate, the connecting head, and the second clamp plate in sequence.
[0006] As a further improvement of this utility model, the friction assembly further includes a washer that presses against the other end of the adjusting elastic member and is sleeved on the screw.
[0007] As a further improvement of this utility model, the outer ring diameter of the gasket is larger than the outer ring diameter of the friction ring, and the inner ring diameter of the gasket is larger than the inner ring diameter of the friction ring but smaller than the outer ring diameter of the friction ring.
[0008] As a further improvement of this utility model, a first mounting groove is formed on the first clamping plate for inserting the friction ring, the adjusting elastic element, and the shim; a second mounting groove is formed on the second clamping plate for inserting the screw, and an internal thread matching the screw is formed on the inner wall of the second mounting groove.
[0009] As a further improvement of this utility model, a through hole is formed on the connecting round head for the screw to pass through, and the diameter of the through hole is smaller than the diameter of the friction ring.
[0010] As a further improvement of this utility model, it also includes a rotating base disposed on the slide, the connecting round head being hinged to the rotating base, and the direction of rotation of the connecting round head on the rotating base being different from the direction of rotation of the movable clamp on the connecting round head.
[0011] As a further improvement of this utility model, a fixing plate extending outward is formed on each side of the rotating base, a fixing screw hole is formed on the fixing plate, and a sliding plate screw hole matching the fixing screw hole is formed on the sliding plate.
[0012] As a further improvement of this utility model, the upper end of the movable clamp is a hollow cylinder, and a through fixing hole is formed on the outer wall of its upper end.
[0013] As a further improvement of this utility model, the adjusting elastic element is a spring.
[0014] As a further improvement of this utility model, the connecting round head is a connecting round head made of carbon limiting material, and the slide plate is a slide plate made of carbon fiber material.
[0015] The beneficial effects of this utility model are as follows:
[0016] This cleanroom-specific mop board is designed with a movable clamp at the lower end of the mop handle and a slip plate hinged to the movable clamp. The lower end of the movable clamp has a downward-extending first clamp and a downward-extending, symmetrical second clamp. The slip plate has an upward-extending connecting head inserted between the first and second clamps. It also includes a friction assembly passing through the movable clamp and the connecting head. The friction assembly includes a friction ring embedded in the first clamp, an adjusting elastic element with one end pressing against the friction ring, and a screw passing through the adjusting elastic element, the friction ring, the first clamp, the connecting head, and the second clamp in sequence. A conventional mop handle is fixed to the movable clamp. The lower end of the slip plate has cleaning components such as cotton cloth or cotton swabs. When the slip plate needs to be rotated, force is applied to the mop handle, causing the movable clamp to rotate around the connecting head, thus rotating the slip plate on the connecting head. This allows the slip plate to be adjusted to a specific angle for cleaning narrow or irregular areas such as corners and furniture edges. When the movable clamp rotates around the connecting round head, the friction ring embedded in the first clamping plate distributes the rotational force of the movable clamp, making the pressure applied by the screw on the movable clamp even. This effectively reduces bending and deformation at the connection between the movable clamp and the connecting round head during use, and provides even and precise pressure to the movable clamp. This ensures stable rotation of the movable clamp while maintaining a stable connection with the connecting round head. Furthermore, an adjusting elastic element is provided between the friction ring and the screw. This adjusting elastic element further adjusts the pressure applied by the screw to the friction ring, so that the pressure of the screw on the movable clamp during rotation can be adjusted to a suitable pressure. This prevents the screw from excessively squeezing the movable clamp, causing it to be unable to rotate, or from being too loose, causing the movable clamp to rotate arbitrarily. This effectively ensures the smoothness of the movable clamp's rotation and its stability when not rotating, improving the user experience, facilitating daily use, reducing wear and tear on the movable clamp from the screw, and ensuring the service life of this cleanroom-specific mop board.

[0024] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods of this utility model will be described in detail below with reference to the accompanying drawings and preferred embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0028] Please refer to Figures 1 to 5This utility model provides a cleanroom-specific mop board with a friction device, including a movable clamp 1 disposed at the lower end of the mop handle, and a drag plate 2 hinged to the movable clamp 1. The lower end of the movable clamp 1 forms a downwardly extending first clamp 11 and a downwardly extending second clamp 12 symmetrical to the first clamp 11. The drag plate 2 is provided with an upwardly extending connecting round head 3 inserted between the first clamp 11 and the second clamp 12. It also includes a friction assembly 4 passing through the movable clamp 1 and the connecting round head 3. The friction assembly 4 includes a friction ring 41 embedded in the first clamp 11, an adjusting elastic element 42 with one end pressing against the friction ring 41, and a screw 43 passing through the adjusting elastic element 42, the friction ring 41, the first clamp 11, the connecting round head 3, and the second clamp 12 in sequence.
[0029] The mop handle is fixed to the movable clamp 1. The lower end of the mop plate 2 is equipped with cleaning components such as cotton cloth or cotton swabs. When the mop plate 2 needs to be rotated, force is applied to the mop handle, causing the movable clamp 1 to rotate around the connecting round head 3. This causes the mop plate 2, mounted on the connecting round head 3, to rotate relative to the connecting round head 3, allowing the mop plate 2 to be adjusted to a specific angle for cleaning narrow or irregular areas such as corners and furniture edges. When the movable clamp 1 rotates around the connecting round head 3, the friction ring 41 embedded in the first clamp 11 distributes the rotational force of the movable clamp 1, ensuring even pressure from the screw 43. This achieves precise screw pressure, effectively reducing bending and deformation at the connection between the movable clamp 1 and the connecting round head 3 during use, and providing balanced and precise pressure to the movable clamp 1. On the chuck 1, the movable chuck 1 ensures stable connection with the connecting round head 3 while also achieving stable rotation. Furthermore, an adjusting elastic element 42 is provided between the friction ring 41 and the screw 43. This adjusting elastic element 42 further adjusts the pressure exerted by the screw 43 on the friction ring 41, ensuring that the pressure on the movable chuck 1 from the screw 43 during rotation can be adjusted to a suitable level. This prevents the screw 43 from excessively squeezing the movable chuck 1, causing it to be unable to rotate, or from being too loose, causing the movable chuck 1 to rotate arbitrarily. This effectively ensures the smoothness of the movable chuck 1's rotation and its stability when not rotating, improving the user experience, facilitating daily use, reducing wear and tear on the movable chuck 1 from the screw 43, and guaranteeing the service life of this cleanroom-specific mop board. The mop handle, cotton strips, and cotton pads are conventional components in this field and will not be described in detail in this embodiment.
[0030] Preferred, such as Figures 1 to 4As shown, the friction assembly 4 also includes a washer 44 that presses against the other end of the adjusting elastic element 42 and is sleeved on the screw 43. The washer 44 buffers the pressure applied to the screw 43, achieving a good wear protection effect and bearing frictional wear. In addition, the washer 44 can also buffer vibration and impact. When the movable clamp 1 rotates on an obstacle or uneven ground, the washer 44 can buffer part of the impact force, reducing damage to the movable clamp 1 and connecting round head 3 and other components, further ensuring the service life of this cleanroom-specific mop board and facilitating daily use.
[0031] Preferred, such as Figures 2 to 4 As shown, the outer ring diameter of the gasket 44 is larger than the outer ring diameter of the friction ring 41, and the inner ring diameter of the gasket 44 is larger than the inner ring diameter of the friction ring 41 but smaller than the outer ring diameter of the friction ring 41. This effectively prevents the friction ring 41 from shifting and falling off through the gasket 44 during use, thus ensuring the normal operation of the friction assembly 4.
[0032] Regarding the specific manner in which the friction assembly 4 passes through the movable clamp 1 and the connecting round head 3, as follows: Figures 1 to 5 As shown, the first clamping plate 11 has a first mounting groove 111 for inserting the friction ring 41, the adjusting elastic element 42, and the washer 44. The second clamping plate 12 has a second mounting groove 121 for inserting the screw 43. The inner wall of the second mounting groove 121 has an internal thread 122 that matches the screw 43. The stud of the screw 43 passes through the washer 44, the adjusting elastic element 42, the friction ring 41 in the first mounting groove 111, to the connecting round head 3, and into the second mounting groove 121. The outer side of the stud has an external thread that matches the internal thread 122 on the second mounting groove 121. This allows the stud to be directly bolted into the second mounting groove 121 after passing through the washer 44, the adjusting elastic element 42, the friction ring 41, and the connecting round head 3, saving the cost of nuts and making it easy to assemble and use.
[0033] Preferred, such as Figures 1 to 4 As shown, the diameter of the screw 43's nut is larger than the diameter of the first mounting groove 111, so that the screw 43's nut covers the first mounting groove 111. When tightening the screw 43, external moisture, dust, and other substances will not enter the first mounting groove 111, ensuring the normal use of structures such as the friction ring 41, adjusting elastic element 42, and washer 44, and reducing wear. The outer diameter of the washer 44 can be larger than the diameter of the first mounting groove 111, that is, the washer 44 is installed outside the first mounting groove 111; the diameter of the washer 44 can also be smaller than the diameter of the first mounting groove 111, that is, the washer 44 is installed inside the first mounting groove 111. It can be set according to the actual situation, so it is not limited in this embodiment.
[0034] Preferred, such as Figure 3 As shown, a through hole 31 is formed on the connecting round head 3 for the screw 43 to pass through. The stud of the screw 43 passes through the through hole 31 to reach the second mounting groove 121 for bolt fixing. The diameter of the through hole 31 is smaller than the diameter of the friction ring 41, thereby effectively preventing the friction ring 41 from being pulled through the first mounting groove 111 and falling into the through hole 31 when the stud of the screw 43 passes through the friction ring 41, thus preventing the friction ring 41 from properly distributing the pressure on the movable clamp 1 and allowing the screw 43 to provide precise pressure. This further ensures the normal use of this cleanroom-specific mop board.
[0035] Preferred, such as Figures 1 to 4 As shown, to make this cleanroom-specific mop board more practical, it also includes a rotating base 5 mounted on the mop plate 2. The connecting round head 3 is hinged to the rotating base 5, allowing the connecting round head 3 to rotate around the rotating base 5 as an axis. Furthermore, the direction of rotation of the connecting round head 3 on the rotating base 5 is different from the direction of rotation of the movable clamp 1 on the connecting round head 3. This allows the cleanroom-specific mop board to rotate at more angles, flexibly conforming to uneven surfaces, corners, and the bottom of furniture, avoiding the problems of traditional fixed mop heads being "out of reach" and "not cleaning properly." It is suitable for cleaning corners and edges, facilitating daily use and improving the practicality of this cleanroom-specific mop board.
[0036] In order to better fix the rotating base 5 to the slide plate 2 for driving, such as Figures 1 to 4 As shown, a fixed plate 51 extending outward is formed on each side of the rotating base 5. The fixed plate 51 has a fixing screw hole 52, and the drag plate 2 has a drag plate screw hole 21 that matches the fixing screw hole 52. The external screws pass through the fixing screw hole 52 and the drag plate screw hole 21 and are fitted with nuts to firmly fix the rotating base 5 to the drag plate 2, forming a rigid connection. This can effectively resist the impact of external forces generated during the use of this cleanroom-specific mop board (such as dragging, rotating, and collision), and prevent the rotating base 5 and the drag plate 2 from loosening due to long-term stress. Furthermore, the outward extension structure of the fixed plate 51 increases the contact area between the rotating base 5 and the drag plate 2, so that the external force is evenly transmitted to the drag plate 2 through the fixed plate 51, avoiding the deformation or damage of components caused by excessive local stress, such as the breakage of the connection point between the rotating base 5 and the drag plate 2.
[0037] Regarding the specific structural configuration of the movable chuck 1, as follows: Figures 1 to 5As shown, the upper end of the movable clamp 1 is a hollow cylinder, and a through fixing hole 13 is formed on the outer wall of its upper end. The external mop handle can be inserted into the hollow position of the movable clamp 1, and the external mop handle can be fixed in the hollow position of the movable clamp 1 by a screw or shaft through the through fixing hole 13, thus completing the assembly of the mop handle.
[0038] Preferred, such as Figures 2 to 4 As shown, the adjusting elastic element 42 is a spring. Springs are inexpensive and have good elastic potential energy. They can generate force through their own elastic deformation to adjust the pressure of components such as the friction ring 41 and the gasket 44. In addition, they have strong fatigue resistance, which effectively ensures the service life of this friction assembly 4.
[0039] Preferably, the connecting head 3 is made of carbon fiber, and the slide plate 2 is made of carbon fiber. Carbon fiber is a high-strength, high-modulus fiber material with a carbon content of over 90%. Its tensile strength is much higher than that of steel, and it is not easy to break when subjected to great tensile force. It also has a high elastic modulus, so its deformation is minimal when subjected to force, which can maintain the stability and precision of the structure and effectively guarantee the service life of this cleanroom-specific mop board. In addition, its density is low and its overall weight is light, which is conducive to people applying force when using it.
[0040] It should be noted that the cleanroom-specific mop board with friction device disclosed in this utility model is an improvement on the specific structure, but the specific control method is not an innovation of this utility model. The springs, cotton cloth, cotton strips, mop handles, screws, bolts, washers, and other components involved in this utility model can be general standard parts or components known to those skilled in the art. Their structure, principle, and control method are all known to those skilled in the art through technical manuals or conventional experimental methods.
[0041] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, other structures obtained by using the same or similar technical features as the above embodiments of the present utility model are all within the protection scope of the present utility model.
