DETAILED DESCRIPTION

[0032] In order to make the personnel of the prior art better understand the utility model scheme, below will combine the drawings in the utility model embodiment, and the technical scheme in the utility model embodiment is clearly and completely described, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor should belong to the scope of the protection of the utility model.

[0033] As Figures 1-6 The utility model provides a wiping article clamping mechanism, including carousel 1, first clamping piece 2, second clamping piece 3 and the bottom plate 4 that can be held with first clamping piece 2, second clamping piece 3 cooperation clamps wiping article, in this embodiment, in order to limit carousel 1, still be provided with cover plate 5, this cover plate 5 and bottom plate 4 upper and lower confrontation, first clamping piece 2 and second clamping piece 3 are located between cover plate 5 and bottom plate 4. Certainly, in other embodiments, also can not set up cover plate 5, but utilizes other structure to limit carousel 1, guarantees the cooperation between carousel 1 and first clamping piece 2, second clamping piece 3, and specific limitation is not made.

[0034] The lower surface of carousel 1 and first clamping piece 2, the lower surface of carousel 1 and second clamping piece 3 are provided with drive convex part 11 and movable track 21, the specific setting position of drive convex part 11 and movable track 21 is not limited here, drive convex part 11 can be provided in carousel 1, movable track 21 is set in first clamping piece 2, second clamping piece 3 at this time, drive convex part 11 can also be provided in first clamping piece 2, second clamping piece 3, movable track 21 is set in carousel 1 at this time.

[0035] The rotating disc 1 can rotate circumferentially under the action of external force, and the driving protrusions 11 and the movable tracks 21 slide against each other, so that the first clamping member 2 and the bottom plate 4 are close to or away from each other, and the second clamping member 3 and the bottom plate 4 are close to or away from each other. When the first clamping member 2 and the second clamping member 3 are away from the bottom plate 4, the wiping material can be placed between the first clamping member 2 and the bottom plate 4 and between the second clamping member 3 and the bottom plate 4. When the first clamping member 2 and the second clamping member 3 are close to the bottom plate 4, the wiping material is firmly clamped by the first clamping member 2 and the bottom plate 4 and the second clamping member 3 and the bottom plate 4.

[0036] Specifically, in the embodiment, as shown in Figure 8 The rotating disc 1 is a circular rotating disc, the driving protrusions 11 are arranged on the lower surface of the rotating disc 1, and the number of the driving protrusions 11 is at least two, which are symmetrically arranged along the radial direction of the rotating disc 1, and the driving protrusions 11 are located on the lower surface close to the outer edge of the rotating disc 1, that is, the driving protrusions 11 are arranged away from the center of the rotating disc 1.

[0037] The movable track 21 is a groove arranged on the first clamping member 2 and the second clamping member 3, and the driving protrusion 11 falls into the groove. In the embodiment, the movable track 21 is a runway-shaped straight groove, which extends along the length direction of the first clamping member 2 and the second clamping member 3. In the drawing of the embodiment, the first clamping member 2 and the second clamping member 3 are arranged on both sides of the length direction of the bottom plate 4, at this time, the movable track 21 extends along the length direction of the first clamping member 2 and the second clamping member 3. Of course, in other embodiments, the first clamping member 2 and the second clamping member 3 can also be arranged on both sides of the width direction of the bottom plate 4, at this time, the movable track 21 can extend along the width direction of the first clamping member 2 and the second clamping member 3.

[0038] It should be noted that the movable track 21 extends along the length direction of the first clamping member 2 and the second clamping member 3, which does not limit that the movable track 21 is parallel to the outer edge of the first clamping member 2, but only describes the general trend of the movable track 21. In other embodiments, the movable track 21 is not necessarily a straight line, which can be arc-shaped, and the movable track 21 is not necessarily a groove, which can be a sliding track defined by a side wall protruding from the surface of the first clamping member 2, which is not limited in particular.

[0039] More specifically, in the embodiment, the driving protrusion 11 is cylindrical, and the outer diameter thereof is substantially equal to the width of the runway-shaped straight groove, or the outer diameter of the driving protrusion 11 is slightly smaller than the width of the groove. As shown in Figure 5As shown, a limiting protrusion 211 is arranged on the inner wall of the movable track 21, which is located on the side wall of the movable track 21 away from the rotating disc 1. When the driving protrusion 11 is moved to the position between the limiting protrusions 211 at the end of the movable track 21, and an external force is applied to pull the first clamping piece 2 and the second clamping piece 3 away from each other, the driving protrusion 11 is subjected to a transverse force, which can be decomposed into a component force along the radial direction towards the center of the rotating disc 1 and another component force perpendicular to the component force. Under the action of the limiting protrusion 211, the other component force is cancelled, leaving only the component force towards the center of the rotating disc 1. Therefore, the rotating disc 1 will not be easily driven to rotate, effectively avoiding the situation that the first clamping piece 2 and the second clamping piece 3 move away from each other, resulting in that the wiping material cannot be stably clamped. In other words, the above-mentioned limiting protrusion 211 plays a good self-locking role when the first clamping piece 2 and the second clamping piece 3 clamp the wiping material.

[0040] In order to illustrate the specific arrangement position of the movable track 21 on the first clamping piece 2 and the second clamping piece 3, as shown in Figure 11 As shown, a part of the first clamping piece 2 extends towards the second clamping piece 3 to form a first side wing 22, and the first side wing 22 is provided with a movable track 21. A part of the second clamping piece 3 extends towards the first clamping piece 2 to form a second side wing 31, and the second side wing 31 is provided with a movable track 21. In other words, the movable track 21 on the first clamping piece 2 is arranged at a position corresponding to the second clamping piece 3, and the movable track 21 on the second clamping piece 3 is arranged at a position corresponding to the first clamping piece 2.

[0041] In order to increase the structural firmness and provide stable support for the translation of the first side wing 22 and the second side wing 31, as shown in Figure 9 As shown, a second supporting portion 32 is formed on the second clamping piece 3 at a position corresponding to the first side wing 22, which provides an upward supporting action for the first side wing 22 and increases the firmness of the second clamping piece 3. A first supporting portion 24 is formed on the first clamping piece 2 at a position corresponding to the second side wing 31, which provides an upward supporting action for the second side wing 31 and increases the firmness of the first clamping piece 2.

[0042] In order to reduce the volume of the wiping material clamping mechanism and ensure the assembly stability of the rotating disc 1, the first clamping piece 2 and the second clamping piece 3 are both provided with a recessed portion 23, and the rotating disc 1 is just fitted into the recessed portion 23, so that the top surface of the rotating disc 1 can be flush with the top surfaces of the first clamping piece 2 and the second clamping piece 3.

[0043] In the process of moving the first clamping piece 2 and the second clamping piece 3 away from or towards the bottom plate 4, in order to ensure that they can translate in the entire length direction without deviation, which may cause the first clamping piece 2 and the second clamping piece 3 not to be in alignment, as shown in Figure 5 , Figure 10As shown, the first clamping piece 2 is provided with a long strip-shaped positioning groove 25 extending along the width direction thereof, which is parallel or tends to be parallel to the width direction side edge of the bottom plate 4, and the cover plate 5 is provided with a positioning protruding rib 51 which can be inserted into the positioning groove 25, so that when the first clamping piece 2 and the second clamping piece 3 move relative to the bottom plate 4, the positioning protruding rib 51 translates and slides in the positioning groove 25, at this time, the positioning protruding rib 51 and the positioning groove 25 form a stable positioning effect, which ensures the translation of the first clamping piece 2.

[0044] The number of the long strip-shaped positioning grooves 25 can be multiple, which are arranged in parallel and at intervals along the length direction of the first clamping piece 2, that is, the positioning grooves 25 can be arranged at the middle position and the two side positions of the first clamping piece 2. In the embodiment, at least one long strip-shaped positioning groove 25 is arranged at the position of the first side wing 22, so that the length of the long strip-shaped positioning groove 25 is increased as much as possible.

[0045] Similarly, the second clamping piece 3 is also provided with a long strip-shaped positioning groove extending along the width direction thereof, and the cover plate 5 is provided with a positioning protruding rib at the corresponding position, and the number of the positioning grooves 25 can be multiple, which are arranged in parallel and at intervals along the length direction of the second clamping piece 3.

[0046] In order to realize the assembly connection of the cover plate 5 and the first clamping piece 2 and the second clamping piece 3, the positioning protruding rib 51 can be formed with an anti-falling buckle 511, which is used to form an anti-falling cooperation with the first clamping piece 2 or with the second clamping piece 3, that is, to prevent the first clamping piece 2, the second clamping piece 3 and the cover plate 5 from separating upward and downward.

[0047] In order to facilitate the stable grasping of the wiping material, as shown, Figure 10 As shown, the lower surface of the cover plate 5 is provided with two rows of downward pressing ribs 52, which are arranged close to the outer edge of the cover plate 5, and the lower surface of the downward pressing rib 52 is inclinedly arranged, specifically, the height of the downward pressing rib 52 gradually increases from inside to outside, so that when the first clamping piece 2 moves away from the bottom plate 4, the outer side of the first clamping piece 2 away from the second clamping piece 3 protrudes downward compared to the bottom plate 4 under the action of the downward pressing rib 52, that is, a height difference is formed between the lower surface of the first clamping piece 2 and the bottom plate 4, which is more conducive to clamping the wiping material. Of course, the lower surface of the downward pressing rib 52 can also be a horizontal plane, as long as the first clamping piece 2 can move while tilting downward when moving away from the bottom plate 4. Similarly, when the second clamping piece 3 moves away from the bottom plate 4, the outer side of the second clamping piece 3 away from the first clamping piece 2 protrudes downward compared to the bottom plate 4 under the action of the downward pressing rib 52, that is, a height difference is formed between the lower surface of the second clamping piece 3 and the bottom plate 4, which is conducive to clamping the wiping material.

[0048] As shown, Figure 7As shown, the side walls of the first clamping member 2 and the bottom plate 4, and the side walls of the second clamping member 3 and the bottom plate 4 are both provided with engaging teeth 26, so as to clamp the wipe more firmly. Figure 1 、 Figure 7 As shown, the lower surfaces of the first clamping member 2 and the second clamping member 3 are provided with conical protrusions 27, which are also more conducive to the firm gripping of the wipe.

[0049] The working process of the wipe clamping mechanism is to Figure 3 Taking the direction shown as an example, apply external force to rotate the turntable 1 counterclockwise (the specific transmission structure is not limited at this time, as long as the rotation of the turntable 1 can be achieved), and the driving protrusion 11 passes over the limiting protrusion 211 and moves in the movable track 21, so that the first clamping member 2 and the second clamping member 3 move away from each other, thereby forming a clamping gap between the first clamping member 2 and the base plate 4, and between the second clamping member 3 and the base plate 4, and the wiping object can be extended into the clamping gap; then rotate the turntable 1 clockwise, and the driving protrusion 11 enters the limit of the limiting protrusion 211 and the end face of the movable track 21, and the first clamping member 2 and the second clamping member 3 respectively act on the base plate 4 to firmly clamp the wiping object.

[0050] like Figure 12 、 Figure 13 As shown, a mop includes a mop rod 6 and a wiping material clamping mechanism of the above structure. The mop rod 6 has a transmission shaft 61 connected to the turntable 1. The transmission shaft 61 is provided with a dial button 611. The dial button 611 protrudes from the outer wall of the mop rod 6. When an external force is applied to the dial button 611 to drive the transmission shaft 61 to rotate around its own axis, the turntable 1 can be driven to rotate circumferentially.

[0051] The above specific implementation methods are used to illustrate the present invention rather than to limit the present invention.
