Description

Technical Field

[0001] This utility model relates to a clamping structure and a cleaning tool. Background Technology

[0002] Currently, when fixing flexible objects (such as wiping materials) to a base, they are generally secured using clamping devices on the base. During operation, the user needs to manually open the clamping devices, place the object (such as the wiping material) in the open position of the clamping devices, and finally close the clamping devices to hold the object (such as the wiping material). This process is cumbersome and results in a poor user experience. Summary of the Invention

[0003] The purpose of this invention is to provide a clamping structure and a cleaning tool that can solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A clamping structure includes a base, on which a movable cavity with at least a lower opening is provided. A driving member and a clamping member are movably disposed in the movable cavity. One end of the driving member is rotatably disposed relative to the base, and the other end of the driving member is rotatably disposed relative to the head of the clamping member. A pressing part extends from the driving member. When clamping an object, the pressing part of the driving member presses on the object to be clamped. Pressing the base causes the driving member to move into the movable cavity and drive the clamping member to move accordingly. Due to the restriction of the side wall of the movable cavity, the tail of the clamping member is brought close to the driving member, and the clamped part of the object is located between the clamping member and the driving member. Pressing the base continues until the clamping member and the driving member are retracted into the movable cavity, and the clamped part of the object is tightly clamped between the clamping member and the driving member.

[0005] Preferably, the tail of the clamping member and / or the driving member are provided with a plurality of teeth.

[0006] Preferably, a first reset member is provided between any two of the base, the drive member, and the clamping member to move the tail of the clamping member away from the drive member.

[0007] Preferably, one of the driving member and the clamping member is provided with a pivot hole, and the other is provided with a pivot shaft. The pivot shaft is rotatably mounted in the pivot hole, the first reset member is mounted on the pivot shaft, and an anti-detachment structure is provided between the driving member and the clamping member.

[0008] Preferably, the base is provided with a locking structure to lock the driving member and the clamping member in the movable cavity.

[0009] Preferably, the locking structure includes a locking part disposed on the driving member and a movable lock slidably disposed on the base. A second reset member is provided between the movable lock and the base. When the driving member retracts into the movable cavity, the locking part pushes open the movable lock. When the driving member retracts into the position, the movable lock is reset under the action of the second reset member and cooperates with the locking part so that the driving member and the clamping object cannot be dislodged from the movable cavity.

[0010] Preferably, the locking part is a locking protrusion with a triangular cross-section, and the movable lock is provided with a locking position with an inclined surface opposite to the locking protrusion.

[0011] Preferably, the base has a sliding groove for the movable lock to slide in, the base has an extension opening that communicates with the sliding groove, and the movable lock has an operating part that can extend out of the base from the extension opening.

[0012] Preferably, the base is provided with a notch that communicates with the movable cavity and allows the object to be clamped to extend out.

[0013] This utility model also provides a cleaning tool, which has the above-described clamping structure.

[0014] Compared with existing technologies, the advantages of this utility model are as follows: Using the above structure, simply pressing down on the base retracts the driving component and the clamping component into the movable cavity, thus clamping the object between them. Operation is extremely convenient and easy, without jamming, providing a good user experience. The structure is simple and compact, clamping is reliable, the overall appearance is aesthetically pleasing, and the cost is low. Applying this clamping structure to cleaning tools can be used to clean floors, glass, walls, countertops, etc. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] like Figures 1-11As shown, this utility model provides a clamping structure, including a base 1. The base 1 has a movable cavity 2 with at least a lower opening. A driving member 3 and a clamping member 4 are movably disposed in the movable cavity 2. One end of the driving member 3 is rotatably disposed relative to the base 1. The relative rotation arrangement can be as follows: a rotating arm 5 extends from the driving member 3, and the rotating arm 5 is directly or indirectly rotatably connected to the base 1 through a rotating shaft 6 cooperating with a rotating hole 7. Alternatively, the relative rotation arrangement between the driving member and the base can be as follows: the driving member is directly or indirectly rotatably connected to the base through a flexible member. The other end of the driving component 3 is rotatably configured relative to the head of the clamping component 4. This relative rotation can be achieved by having one of the driving component 3 and the clamping component 4 have a pivot hole 8, and the other has a pivot shaft 9. The pivot shaft 9 is rotatably mounted in the pivot hole 8. An anti-detachment structure is provided between the driving component 3 and the clamping component 4. Specifically, the pivot hole 8 is located on the driving component 3, and the pivot shaft 9 is located on the clamping component 4. After the pivot shaft 9 is inserted into the pivot hole 8, the anti-detachment structure is an anti-detachment protrusion 10 on the pivot shaft 9. The anti-detachment protrusion 10 engages with the driving component 3, preventing the pivot shaft 9 from detaching from the driving component 3, thus preventing the driving component and the clamping component from separating. Alternatively, the anti-detachment structure can be an anti-detachment groove on the pivot shaft, with an anti-detachment protrusion on the driving component that cooperates with the anti-detachment groove. The anti-detachment protrusion engages with the anti-detachment groove, preventing the driving component and the clamping component from separating. Other forms of anti-detachment structures are also acceptable, as long as they prevent the driving component and the clamping component from separating. The relative rotation arrangement of the driving component 3 and the clamping component 4 can also be configured as follows: both the driving component 3 and the clamping component 4 are provided with opposing pivot holes, and the driving component and the clamping component are rotated together by a pivot shaft passing through the two pivot holes. Alternatively, the relative rotation arrangement of the driving component and the clamping component can be configured as follows: the driving component is integrated with the clamping component through a flexible component, and because the flexible component has a certain degree of flexibility, the clamping component can rotate relative to the driving component. The driving member 3 has a pressing part 11 extending from it. When clamping an object, the pressing part 11 of the driving member 3 presses on the object to be clamped 12. Pressing the base 1 causes the driving member 3 to move into the movable cavity 2 and drive the clamping member 4 to move accordingly. Due to the restriction of the side wall of the movable cavity 2, the tail of the clamping member 4 is close to the driving member 3, and the clamped part of the object to be clamped 12 is located between the clamping member 4 and the driving member 3. Pressing the base 1 continues until the clamping member 4 and the driving member 3 are closed in the movable cavity 2, and the clamped part of the object to be clamped 12 is clamped between the clamping member 4 and the driving member 3.

[0028] In use, the object to be clamped 12 (such as a wiping material) is placed on the ground or table. Then, the pressing part 11 of the driving member 3 is pressed onto the object to be clamped 12 (such as a wiping material). Then, the base 1 is pressed down, and the driving member 3 moves upward toward the movable cavity 2. One end of the driving member 3 rotates around the base 1, while the other end drives the clamping member 4 to move upward toward the movable cavity 2. Due to the restriction of the side wall of the movable cavity 2, that is, the side wall at the opening of the movable cavity 2 directly or indirectly abuts against the outer wall of the clamping member 4 and slides along the outer wall of the clamping member 4, thereby causing the tail of the clamping member 4 to rotate around its head. At the same time, the tail of the clamping member 4 approaches the driving member 3. The pressing part 11 is used to clamp the object 12 (such as a wiping material). At this time, the upwardly arched clamped portion is located between the pressing part 11 of the driving member 3 and the tail of the clamping member 4. Continuing to press down on the base 1, under the mutual compression of the base 1 and the ground or countertop, the driving member 3 and the clamping member 4 retract together into the movable cavity 2. Because the side wall of the movable cavity 2 directly or indirectly abuts against the outer wall of the clamping member 4, the clamped portion of the object 12 (such as a wiping material) is tightly clamped between the clamping member 4 and the driving member 3. The operation is very convenient and easy, without jamming, providing a good user experience. The structure is simple and compact, the clamping is reliable, the overall appearance is beautiful, and the cost is low. This utility model, after clamping the wiping material, can be used as a cleaning tool for cleaning floors, glass, walls, countertops, etc.

[0029] Preferably, the tail of the clamping member 4 and / or the driving member are provided with a plurality of teeth 13. The teeth 13 on the clamping member 4 are used for picking up and clamping. That is, when the tail of the clamping member 4 moves close to the driving member 3 and upward toward the movable cavity 2, the teeth 13 will pick up the clamped part of the object to be clamped 12 (such as a wiping object) and move it close to the pressing part 11. At the same time, the pressing part 11 will press down on the object to be clamped 12 (such as a wiping object), so that the clamped part of the object to be clamped 12 (such as a wiping object) forms an arch between the driving member 3 and the clamping member 4. When the driving member and the clamping member are closed in the movable cavity, the clamped part of the object to be clamped 12 (such as a wiping object) is clamped between the teeth of the driving member and the clamping member. The teeth on the driving member are used for clamping, which can firmly fix the clamped part of the object to be clamped 12 (such as a wiping object) between the driving member 3 and the clamping member 4. The clamping device has teeth, while the drive unit may or may not have teeth. When the drive unit has teeth, the clamping effect is enhanced, resulting in better clamping and a more secure fixation. It is also more adaptable to objects of varying thicknesses (such as objects to be wiped). Furthermore, during the clamping process, the teeth automatically retract and are not exposed, so they will not damage the surface to be wiped.

[0030] Preferably, a first reset member 14 is provided between any two of the base 1, the drive member 3, and the clamping member 4 to move the tail of the clamping member 4 away from the drive member 3. The first reset member 14 is mounted on the pivot shaft 9. Specifically, the first reset member 14 is preferably a torsion spring, which is fitted onto the pivot shaft 9. One end of the torsion spring abuts against the clamping member 4, and the other end abuts against the drive member 4. When it is necessary to disengage the drive member 3 and the clamping member 4 from the movable cavity 2, the torsion spring can be used to achieve this. That is, the torsion spring can open the tail of the clamping member 4 relative to the drive member 3, and the head of the clamping member 4 rotates around the drive member 3 and is pushed by the side wall of the movable cavity 2, thereby pulling the drive member 3 to rotate around the base 1, so that the clamping member 4 and the drive member 3 disengage from the opening of the movable cavity 2, thus automatically releasing the clamped object 12 (such as a wiping object). The above structure has a first reset member positioned between the driving member and the clamping member. The first reset member can also be positioned between the driving member and the base, or between the clamping member and the base. The position of the first reset member only needs to allow the driving member and the clamping member to disengage from the movable cavity.

[0031] Preferably, the base 1 is provided with a locking structure to lock the driving member 3 and the clamping member 4 in the movable cavity 2. Specifically, the locking structure includes a locking part 15 provided on the driving member 3 and a movable lock 16 slidably provided on the base. A second reset member 17 is provided between the movable lock 16 and the base 1. The second reset member 17 is preferably a spring. When the driving member 3 retracts into the movable cavity 2, the locking part 15 pushes open the movable lock 16. When the driving member 3 is retracted into place, the movable lock 16 is reset under the action of the second reset member 17 and cooperates with the locking part 15 so that the driving member 3 and the clamping member 4 cannot be dislodged from the movable cavity 2. When using this invention, pressing down on the base 1 causes the drive member 3 to rotate upwards. The locking part 15 on the drive member 3 moves upwards and opens the movable lock 16. At this time, the spring is in a deformed state. When the drive member 3 retracts into place, the movable lock 16 returns to its original position under the action of the spring and engages with the locking part 15, preventing the drive member 3 from rotating downwards. This prevents the drive member 3 and the clamping part 4 from disengaging from the movable cavity 2 under the action of the torsion spring, thus providing a locking function. This firmly fixes the object to be clamped 12 (such as a wiping object) between the drive member 3 and the clamping part 4. When it is necessary to disassemble the object to be clamped 12 (such as a wiping object), pushing the movable lock 16 removes its engagement with the locking part 15, thus not obstructing the downward rotation of the drive member 3. Due to the action of the torsion spring, the drive member 3 and the clamping part 4 disengage from the opening of the movable cavity 2, completing the disassembly of the object to be clamped 12 (such as a wiping object). Releasing the movable lock 16 causes it to return to its original position under the action of the spring. The aforementioned locking structure is located between the drive component and the base. Alternatively, the locking structure can be located between the clamping component and the base. For example, the locking structure could be a locking block elastically mounted on the base, which can be inserted into the clamping component to lock it in place after the clamping component enters the movable cavity. Other forms of locking structure are also possible, as long as they lock the clamping component and the drive component within the movable cavity.

[0032] Preferably, the locking part 15 is a locking protrusion with a triangular cross-section. The movable lock 16 is provided with a locking position 18, which has an inclined surface opposite to the locking protrusion. When the present invention is in the open state, the locking protrusion is located below the locking position 18. Pressing the base 1 causes the driving member 3 to rotate upward, which can push open the locking position 18 through the locking protrusion, thereby opening the movable lock 16. After the locking protrusion passes the locking position 18 upward, the movable lock 16 returns to its original position under the action of the spring, and the locking position 18 returns to its original position, which is located below the locking protrusion, so that the driving member 3 cannot rotate downward, thus achieving the locking function. When the movable lock 16 is pushed, the locking position 18 is not below the locking protrusion, so it will not hinder the locking protrusion from moving downward with the driving member 3. Due to the action of the torsion spring, the driving member 3 and the clamping part 4 are disengaged from the opening of the movable cavity 2, completing the disassembly. During the rotation of the driving member 3, it can contact the locking protrusion through the inclined surface, which plays a guiding role and ensures smooth movement.

[0033] Preferably, the base 1 is provided with a sliding groove 19 for the movable lock 16 to slide in, and the base 1 is provided with an extension 20 communicating with the sliding groove 19. The movable lock 16 is provided with an operating part 21 that can extend out of the base from the extension 20. A base plate 22 is provided below the base 1. The base plate 22 cooperates with the base 1 to limit the movable lock 16 in the sliding groove 19. The structure is simple, and the movable lock 16 can be operated by pushing the operating part 21, making the unlocking operation convenient.

[0034] Preferably, the base 1 is provided with a notch 23 that communicates with the movable cavity 2 and allows the object to be clamped 12 to extend out. That is, the clamped part of the object to be clamped 12 (such as a wiping object) can extend out from the notch 23, which is suitable for objects to be clamped 12 (such as wiping objects) of various lengths.

[0035] This utility model also provides a cleaning tool with the aforementioned clamping structure. The cleaning tool can be a flat mop, a rotary mop, a handheld mop, a glass cleaner, a countertop cleaner, etc., used for cleaning floors, glass, walls, countertops, etc. The movable cavity 2, the driving component 3, and the clamping component 4 are at least one set; when there are two sets, there are two movable cavities 2 located on both sides of the base 1. Each movable cavity 2 contains one driving component 3 and one clamping component 4, thereby clamping both sides of the object to be clamped 12 (such as a wiping object).

[0036] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
