[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0029] Reference Figures 1 to 3 The utility model discloses a mop device with a clamping and locking function, comprising: a mop rod 100 and a mop body 200 connected to one end of the mop rod 100, the mop body 200 is provided with a flat plate 500, the mop body 200 is movably provided with two first clamping plates 300 respectively extending from opposite sides of the flat plate 500, the first clamping plates 300 are connected with a first elastic member 310 for driving the first clamping plates 300 away from the corresponding side of the flat plate 500, the first clamping plates 300 are connected with a switch operating member 320, the two switch operating members 320 are arranged face to face, the mop body 200 is provided with a locking mechanism 400, the locking mechanism 400 can lock the two switch operating members 320 that are brought close to each other so that the two first clamping plates 300 keep clamping the wiping object, or the locking mechanism 400 can release the switch operating member 320 so that the two first clamping plates 300 are away from each other to unload the wiping object.
[0030] When the mop device of the above structure is disassembled and replaced with a wiping object, it is only necessary to act on the locking mechanism 400 to release the switch operating member 320, and the first clamping plates 300 can move away from each other under the action of the first elastic member 310 to remove the wiping object; when installing the wiping object, the two switch operating members 320 are forced to move closer to each other, thereby driving the first clamping plates 300 to approach the side of the corresponding flat member 500 to clamp the wiping object, and the locking mechanism 400 locks the positions of the two switch operating members 320 to maintain the clamping effect on the wiping object.
[0031] See also Figure 2 and Figure 3In some embodiments of the utility model, the two first clamping plates 300 are relatively slidably arranged on the flat member 500, and the locking mechanism 400 includes two first clamping members 410 respectively arranged on the two switch operating members 320, a second clamping member 420 movably arranged on the mop body 200 and matched with the two first clamping members 410, and a second elastic member 430 connected to the second clamping member 420, the two first clamping members 410 are arranged face to face, and the second elastic member 430 can drive the second clamping member 420 to clamp with the two first clamping members 410. It is understandable that when the two switch operating members 320 are forced to move closer to each other, the two first clamping members 410 move closer to each other so as to be able to be combined with the second clamping member 420, and the second elastic member 430 is used to drive the second clamping member 420 and the two first clamping members 410 to maintain a state of being clamped; when it is necessary to unlock this state, it is only necessary to drive the second clamping member 420 to move in the direction of overcoming the elastic force of the second elastic member 430, so that the second clamping member 420 and the first clamping member 410 can be separated, and under the action of the first elastic member 310, the switch operating member 320 and the first clamping plate 300 move together as a whole to release the wipe. The structure of the locking mechanism 400 is simple, and the removal and installation of the wipe are very fast. Of course, in other embodiments, the locking mechanism 400 can also be replaced by a latch member, and accordingly, the mop body 200 and the switch operating member 320 are both provided with a positioning hole for inserting the latch member, but the convenience of the locking mechanism 400 is poor relative to the above scheme.
[0032] See also Figure 2 and Figure 3 In some embodiments of the present invention, the second clamping member 420 is a lifting block located between the two switch operating members 320 and movable up and down relative to the mop body 200, a slot 421 is provided inside the lifting block, and a first through hole 422 communicating with the slot 421 is transversely penetrated through the lifting block, the first clamping member 410 is a hook provided at the end of the switch operating member 320 and capable of entering the slot 421 along the first through hole 422, and the second elastic member 430 is used to drive the lifting block to move upward or downward so that the hook abuts against the side wall of the slot 421, thereby preventing the hook from separating from the slot 421. It can be understood that when the lifting block overcomes the action of the second elastic member 430 and moves to the first through hole 422 to align with the hook, the hook can enter the slot 421 along the first through hole 422, and when the second elastic member 430 is not affected by external force, the lifting block resets and moves so that the hook portion of the hook is located inside the slot 421, and under the action of the first elastic member 310, the first clamping plate 300 and the switch operating member 320 have a tendency to move away from the lifting block, and the hook portion of the hook can abut against the side wall of the slot 421, thereby keeping the wipe clamped.
[0033] See also Figure 2 and Figure 3 In some embodiments of the utility model, the flat plate 500 is provided with a longitudinal guide sleeve 510 for the lifting block to slide, the second elastic member 430 is a compression spring with two ends respectively abutting against the bottom of the longitudinal guide sleeve 510 and the bottom surface of the lifting block, a limiting structure 423 is provided between the mop body 200 and the lifting block to prevent the lifting block from escaping upward, and a side portion of the longitudinal guide sleeve 510 is provided with a clearance hole 520 connected to the inside thereof, and when the lifting block moves downward to the first through hole 422 and the clearance hole 520, the hook can be pulled out along the first through hole 422 and the clearance hole 520. Specifically, the limiting structure 423 is a circle of anti-slip rings provided on the outer periphery of the lifting block, the mop body 200 is provided with a guide hole for the upper part of the lifting block to extend, and the anti-slip ring can abut against the outer peripheral edge of the guide hole to prevent the lifting block from escaping upward from the mop body 200 under the action of the compression spring. When the wipe needs to be removed, the user only needs to apply pressure on the lifting block to move it downward a certain distance, and the hook can be disengaged from the slot 421 and pulled out along the first through hole 422 and the clearance hole 520. The operation is very convenient, and the user does not even need to bend over to operate, but only needs to apply pressure with his feet.
[0034] See also Figure 3 In some embodiments of the utility model, the lower edges of both ends of the first through hole 422 are provided with side plates 424, and the slot 421 is defined between the two side plates 424 and the inner wall of the lifting block. The outer side surface of the side plate 424 is inclined from bottom to top toward the slot 421, and the hook is provided with a first inclined surface 411 matched with the outer side surface of the side plate 424. The first inclined surface 411 can push against the outer side surface of the side plate 424 to drive the lifting block to move downward and make the hook enter the slot 421. When the two switch operating members 320 move closer to each other, the first inclined surface 411 of the hook abuts against the outer side surface of the side plate 424 to drive the lifting block to move downward. After the hook passes over the side plate 424, the lifting block moves upward under the action of the second elastic member 430, and the hook is stabilized in the slot 421, so that the wiping object can be clamped without pressing the lifting block, which is convenient for users to use.
[0035] See also Figure 2 and Figure 3In some embodiments of the utility model, in order to limit the wiping article from being pulled out of the gap between the first clamping plate 300 and the flat member 500 and to improve the clamping force on the wiping article, a second clamping plate 600 opposite to the adjacent first clamping plate 300 is respectively provided on opposite sides of the flat member 500, and the first clamping plate 300 has a first serrated protrusion 330 arranged toward the second clamping plate 600, and the second clamping plate 600 has a second serrated protrusion 610 protruding from the side edge of the flat member 500 and cooperating with the first serrated protrusion 330.
[0036] See also Figure 2 In some embodiments of the present invention, the second clamping plate 600 is connected to a third elastic member 620 that drives it to move toward the corresponding first clamping plate 300 to clamp the wipe. It can be understood that after the locking mechanism 400 locks the position of the first clamping plate 300, the gap between the first clamping plate 300 and the second clamping plate 600 is completely fixed, and there are many types of wipes, such as towels and oil-absorbing papers, and the thickness of the wipes is also different. In this case, the second clamping plate 600 can move slightly along the direction of compressing the third elastic member 620 to better adapt to wipes of different thicknesses and sizes, so as to expand the scope of use.
[0037] See also Figure 2 In some embodiments of the utility model, the flat plate 500 is rectangular, the first clamping plate 300 is extended along the length direction of the flat plate 500, and the first sliders 700 are slidably arranged at both ends of the flat plate 500 along its width direction. The two first sliders 700 are arranged on one flat plate to facilitate smooth sliding. The first clamping plate 300 is rotatably connected to one end of the first slider 700 through a horizontal pivot 710 so as to be able to swing up and down. The first elastic member 310 abuts between the other end of the first slider 700 and the mop body 200. The pivot 710 is provided with a torsion spring member 720 for driving the first clamping plate 300 to swing downward. This design has the effect of swinging downward to clamp the wipe, which is beneficial to improving the stability of clamping the wipe.
[0038] See also Figure 2 and Figure 3In some embodiments of the utility model, the two first sliders 700 on the same first clamping plate 300 are connected by a cross bar 800, the switch operating member 320 is connected to the middle of the cross bar 800 and can move relative to the mop body 200 along the sliding direction of the first slider 700, so as to avoid the switch operating member 320 being located at one end of the first clamping plate 300 and causing the switch operating member 320 to move unsmoothly, and the two switch operating members 320 are provided with a convex strip 321 protruding upward on one side close to each other, and the two convex strips 321 can be grasped by one hand to approach each other so that the locking mechanism 400 locks the relative position of the two first clamping plates 300. It should be noted that the user's thumb is against the outside of one of the convex strips 321, and the four fingers are against the outside of the other convex strip 321. When the user's palm makes a grasping action, the two convex strips 321 can be close to each other, thereby realizing the function of installing the wiping object with one hand, which greatly improves the convenience of use.
[0039] See also Figure 2 and Figure 4 In some embodiments of the utility model, the mop body 200 has a cavity with an opening facing downward, the flat member 500 closes the opening of the cavity to accommodate the first slider 700 and the cross bar 800, the cross bar 800 is provided with a plurality of insertion holes 810, the mop body 200 is provided with a first elongated hole 210 opposite to the insertion hole 810 and extending along the sliding direction of the first slider 700, the switch operating member 320 is provided with a mounting column 322 inserted downward into the insertion hole 810, the mop body 200 is further provided with a second elongated hole 220 parallel to the first elongated hole 210, and the switch operating member 320 is provided with an elastic hook portion 323 that can be inserted downward into the second elongated hole 220 and reciprocate along the second elongated hole 220. It should be noted that openings are provided on opposite sides of the cavity for the first clamping plate 300 to be telescopically moved. The mounting column 322 of the switch operating member 320 passes through the first elongated hole 210 and is inserted into the insertion hole 810 of the cross bar 800. The switch operating member 320 is moved along the sliding direction of the first slider 700 with a simple structure. The elastic hook 323 of the switch operating member 320 is passed through the second elongated hole 220 to prevent the switch operating member 320 from detaching upward from the mop body 200, and also does not affect the normal movement of the switch operating member 320. The above structure is conducive to reducing the difficulty of production, processing and assembly of parts.
[0040] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0041] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
