Description

Technical Field

[0001] The invention relates to the field of mops, and in particular to a clamping component and a cloth-clamped mop. Background Art

[0002] Cleaning tools are widely used in people's daily life, such as mops, window wipers, etc. The cleaning tool has the advantage of replaceable wiping materials.

[0003] For example, Chinese patent CN201310227871.2 relates to a dust mop, which has a mounting mechanism on the mop board to mount a dust cloth or dust paper, and the mounting mechanism includes a clamping device, which is hollow and has a plurality of clamping grooves on the surface, and the four corners of the dust cloth or dust paper are inserted into the clamping grooves for clamping and mounting. However, the dust cloth needs to be touched by hand when installing and removing the dust cloth.

[0004] Another example is Chinese patent CN202221557784.4, which relates to a flat mop with automatic mop changing function. The flat mop uses a handle to drive the gear to rotate and control the activity of the driving plate. The driving plate and the connecting plate automatically clamp the mop during the folding process, and the mop automatically detaches from the mop plate when opening. There is no need to touch the mop when changing the mop. However, the flat mop does not hold the mop stably enough, and the mop is easy to fall off when mopping the floor.

[0005] Therefore, the installation and disassembly structure of the wiper needs to be further optimized. Summary of the invention

[0006] An object of the present invention is to provide a clamping assembly and a cloth-clamped mop that solve the above-mentioned problems.

[0007] To achieve the above-mentioned purpose, the present invention is implemented by the following technical solutions: A clamping assembly includes a movably matched clamping seat and a first clamping member, the outer end of the first clamping member is provided with a first clamping claw, the first clamping claw is movably connected to the first clamping member, a first elastic member is provided between the first clamping claw and the first clamping member, the clamping seat is provided with a first clamping tooth, the first clamping claw is provided with a second clamping tooth, the first clamping member can move towards or away from the clamping seat to change the distance between the first clamping tooth and the second clamping tooth, the first clamping tooth and the second clamping tooth clamp a wipe when they are close to or meshed, the thickness of the wipe changes the clamping distance between the first clamping tooth and the second clamping tooth, the elastic force of the first elastic member keeps the first clamping tooth and the second clamping tooth maintaining a tendency to move towards each other to clamp the wipe. The gap or distance between the two groups of clamping teeth of the existing clamping assembly cannot be adjusted. If the distance between the two groups of clamping teeth increases due to wear and tear, and the thickness of the wipe is smaller than the distance between the two groups of clamping teeth, the wipe is clamped only by inserting or hooking the tip of the clamping teeth onto the wipe, and the installation stability of the wipe is poor. The present invention adds a group of elastically retractable first clamping jaws. Under the original clamping gap, the elastic force of the first elastic member is used to make the first clamping teeth and the second clamping teeth approach and squeeze the wipe, so as to increase the installation firmness of the wipe. When installing a thicker wipe, the existing clamping assembly cannot adjust the distance between the clamping teeth, so the tip of the clamping teeth will pierce the wipe. The wipe is also difficult to separate from the clamping teeth during the expansion of the clamping assembly, and it is necessary to The wiper needs to be torn off by hand, or when the wiper is thick, the clamping assembly cannot move to the preset clamping position and lock the position due to the obstruction of the wiper, and the thicker wiper cannot be installed. The elastically retractable arrangement between the first clamping jaw and the first clamping member in the present invention expands the movable range of one of the clamping teeth. When the wiper is thick, the clamping assembly moves to the preset clamping position and locks. The thickness of the wiper pushes the first clamping jaw to overcome the elastic force of the first elastic member and move to a position away from the first clamping tooth. The elastic force released by the first elastic force and restored to the static state provides the first clamping jaw with a force to approach the first clamping tooth to clamp the wiper, thereby allowing the clamping assembly to clamp wipes with a wider thickness range to meet different cleaning needs.

[0008] Preferably, the first clamping jaw comprises a first clamping section and a first telescopic section, the first clamping section is provided with second clamping teeth, each of the first clamping teeth and each of the second clamping teeth are arranged along the side of the clamping seat, and the first clamping section can be guided to be installed on the first clamping member, so that the first clamping teeth and the second clamping teeth remain parallel when the first clamping jaw moves. Through the guidable connection between the first clamping section and the first clamping member, the activity state and position of each first clamping tooth are unified, and each first clamping tooth simultaneously clamps the wipe and moves away from and releases the wipe.

[0009] Preferably, the first clamping member includes a first sliding section and a first guide groove, the first guide groove and the first sliding section are fixedly connected or the first guide groove is arranged on the first sliding section, the first guide groove is provided with a first stopper, the first telescopic section is provided with a first telescopic hole, the first telescopic hole is provided with a second stopper, the first stopper is inserted into the first telescopic hole for installation, the first stopper and the second stopper are respectively located on opposite sides of the first telescopic hole, and the gap between the first stopper and the second stopper is used to install the first elastic member. The first sliding section is inserted into the first guide groove, and the first sliding section is movable and limited by the inner walls of the first guide groove. The first telescopic hole, the first stopper and the second stopper are arranged, and the first stopper and the second stopper are intersected to extend the length of the first elastic member or the telescopic length of the first elastic member, and the first clamping claw moves outward to drive the second stopper to move outward to squeeze the first elastic member to change the elastic force.

[0010] Preferably, both ends of the first clamping member are provided with a first guide groove, and both ends of the first clamping jaw are provided with a first telescopic section. The two groups of the first guide grooves and the first telescopic section are telescopically movable at the same time to make each of the second clamping teeth move synchronously. The two first guide grooves are fixedly connected by a first connecting beam, and the first sliding section is fixedly connected to the first connecting beam. The outer end of the connecting beam is supported by the inner side of the first clamping jaw. The symmetrical arrangement of the two groups of first guide grooves and the first telescopic section makes the elastic force of the two first elastic members more balanced, so that the first clamping jaw can move inward and outward in a translational manner as a whole. After the first clamping section moves inward to a preset position, it is supported by the first connecting beam to prevent the middle part of the first clamping section from being deformed and bent by the elastic force at both ends.

[0011] Preferably, the first connecting beam is provided with auxiliary teeth, which can cooperate with the second clamping teeth to clamp the wiping object. During the clamping and fixing process, the wiping object is moved and rolled up by the movement of the first clamping section from the flat unfolded state, and the rolled-up part of the wiping object is clamped by the first clamping teeth and the second clamping teeth. The auxiliary teeth are arranged so that when the first clamping jaw moves outward due to the thickness of the wiping object, the gap after the movement can be used to clamp the top of the rolled-up wiping object between the second clamping teeth and the auxiliary teeth, so that the clamping of the wiping object is more stable.

[0012] A cloth mop, comprising a handle and the clamping assembly described above, wherein the clamping seat is provided with a hinge seat movably connected to the handle, the first clamping piece is movably mounted on one of the side edges of the clamping seat, the clamping seat is further provided with a movable second clamping piece on the other side edge relative to the first clamping piece, the second clamping piece is provided with a movable second clamping claw, the first clamping piece is connected to a first connecting rod, the second clamping piece is connected to a second connecting rod, the first connecting rod and the second connecting rod are both rotatably mounted on the hinge seat, the hinge seat can move up and down relative to the clamping seat, at least one guide rod is provided between the clamping seat and the hinge seat, the The guide rod prevents the hinge seat from rotating relative to the first link or the second link. When installing the wiper, the first clamp and the second clamp are in the unfolded state. By pressing the handle or the hinge seat, the guide rod guides the hinge seat to move downward in the vertical direction and simultaneously drives the first link and the second link to move, so that the first clamp and the second clamp move toward each other. The first clamp moves telescopically relative to the first clamp, and the second clamp moves telescopically relative to the second clamp to clamp wipers of different thicknesses. A switch assembly is also provided on the clamp seat, and the switch assembly positions the first clamp and the second clamp in the clamping state. By pressing the handle or the hinge seat to drive the first and second links to move downward and rotate to drive the first and second clamps to move toward each other to clamp the wiper. When installing and removing the wiper, there is no need to directly touch the wiper with hands, which is more hygienic and provides a better experience.

[0013] Preferably, the upper end of the first connecting rod and the upper end of the second connecting rod are rotatably connected to the hinge seat along the first axis, the lower end of the first connecting rod is rotatably connected to the first sliding section along the second axis, and the lower end of the second connecting rod is rotatably connected to the second sliding section on the second clamping member along the third axis. The first clamping member and the second clamping member move from a deployed state to a clamped state, the first axis reduces the height difference with the second axis or the third axis, and when the first clamping member and the second clamping member are in the clamped state, the first axis is located above the second axis or the third axis, so that the first connecting rod and the second connecting rod remain in a pre-deployed state. When the rotation axis between the hinge seat and the first connecting rod and the second connecting rod is different, if the mop rod is not perpendicular to the mop head or pressed on the eccentric position of the mop head, the force on one side of the hinge seat is greater, the force on the first connecting rod and the second connecting rod is uneven, the synchronization between the first connecting rod, the second connecting rod, the first clamping member and the second clamping member is poor, and it is easy for one of the clamping members to move while the other clamping member does not move. The first connecting rod and the second connecting rod are coaxially rotated to make the synchronization of the first connecting rod and the second connecting rod better, and always maintain a state of simultaneous movement or stillness; if the first axis, the second axis and the third axis are located at the same height, when the clamping member is pulled, the forces between the clamping member and the connecting rod, and between the connecting rod and the hinge seat are on the same plane, the hinge seat and the connecting rod are not subjected to upward force, and it is difficult for both to move or rotate upward. The pre-expansion setting of the first connecting rod and the second connecting rod allows the first connecting rod and the second connecting rod to transmit force upward when the cloth mop is switched from the clamping state to the expanded state, so that the activities of the various components of the cloth mop are smoother.

[0014] Preferably, the first sliding section and the second sliding section are stacked up and down, and a second elastic member is connected between the first sliding section and the second sliding section. The elastic force of the second elastic member can drive the first clamping member and the second clamping member to move synchronously in opposite directions to the unfolded state, or by pressing any one of the first clamping member and the second clamping member, the second elastic member can pull the other clamping member, so that the first clamping member and the second clamping member can move synchronously toward each other to the clamping state. The two clamping members are automatically unfolded by the second elastic member. Compared with separately setting the elastic members, setting the second elastic member between the two clamping members can achieve better synchronization between the two clamping members. Even if one of the connecting rods or the clamping members is stuck, the activity of the other connecting rod or the clamping member can be transmitted to the connecting rod or the clamping member through the elastic member to drive its activity, and the activity state between the two clamping members is always kept synchronized.

[0015] Preferably, the first clamping member is further provided with a third sliding section, and the second clamping member is further provided with a fourth sliding section. Both sides of the first connecting rod are rotatably connected to the first sliding section and the third sliding section respectively, so that a connecting ring is formed between the first clamping member and the first connecting rod, and both sides of the second connecting rod are rotatably connected to the second sliding section and the fourth sliding section respectively, so that a connecting ring is formed between the second clamping member and the second connecting rod. During installation, the first sliding section is affixed to the top of the second sliding section, and the third sliding section is affixed to the bottom of the fourth sliding section. The first connecting rod and the second connecting rod are rotatably connected along the first axis, so that the first clamping member, the second clamping member, the first connecting rod, the second connecting rod and the second elastic member are connected into an integral clamping module. The rotationally symmetrical installation structure of the first clamping member and the second clamping member does not need to be deliberately distinguished from the first clamping member and the second clamping member during production and assembly. That is, after the two first clamping members are installed with each other, the first clamping member and the second clamping member are formed by their relative positions, thereby avoiding the situation where two different clamping members are taken or installed incorrectly, and the assembly efficiency is higher; the first clamping member, the second clamping member, the first connecting rod, and the second connecting rod are cross-connected in the form of two connecting rings, so that the two groups of components form an O-shaped chain, which has a simple structure and can be stably connected even without the assistance of screws or snap-on structures. The components are first installed as an integral module and then installed on the clamping seat, which is convenient for assembly on the assembly line and can improve the assembly efficiency of workers.

[0016] Preferably, a movable hole is provided at the center of the clamping seat, and the first connecting rod and the second connecting rod can move up and down in the movable hole, and at least part of the first connecting rod and the second connecting rod is located directly below the handle. When the handle is pressed, the force is directly transmitted to the hinge seat and the connecting rod along the same straight line, the force directions of the two connecting rods are more consistent, and the linkage effect is better.

[0017] The advantages of the present invention are: A set of elastically retractable first clamping claws is added. Under the original clamping gap, the elastic force of the first elastic member is used to make the first clamping teeth and the second clamping teeth approach each other and press toward the wiping object, so as to increase the installation firmness of the wiping object.

[0018] The elastically retractable setting between the first clamping jaw and the first clamping member expands the movable range of one of the clamping teeth. When the wiping material is thicker, the clamping assembly moves to a preset clamping position and is locked. The thickness of the wiping material pushes the first clamping jaw to overcome the elastic force of the first elastic member and move to a position away from the first clamping tooth. The elastic force released by the first elastic force and restored to a static state provides the first clamping jaw with a force to approach the first clamping tooth to clamp the wiping material, thereby allowing the clamping assembly to clamp wiping materials with a wider thickness range to meet different cleaning needs.

[0019] By pressing the handle or the hinged seat, the first connecting rod and the second connecting rod are driven to move downward and rotate to drive the first clamping member and the second clamping member to move toward each other to clamp the wiping object. When installing and removing the wiping object, there is no need to directly touch the wiping object with hands, which is more hygienic and provides a better experience.

[0020] The first connecting rod and the second connecting rod are coaxially rotated to achieve better synchronization between the first connecting rod and the second connecting rod, so that they always maintain a state of simultaneous movement or stillness; the first clamping member and the second clamping member are stacked and connected up and down so that the moving paths of the two have overlapping parts, thereby shortening the length required for the movement of the two, and facilitating linkage in the narrow space of the clamping seat.

[0037] The following describes the embodiments of the present invention in detail in conjunction with the accompanying drawings, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

Example

[0039] like Figure 1-6A clamping assembly 1 includes a clamping seat 2 and a first clamping member 3 that are movably matched. A first clamping jaw 4 is provided at the outer end of the first clamping member 3. The first clamping jaw 4 is movably connected to the first clamping member 3. A first elastic member 5 is provided between the first clamping jaw 4 and the first clamping member 3. The clamping seat 2 is provided with a first clamping tooth 6. The first clamping jaw 4 is provided with a second clamping tooth 7. The first clamping member 3 can move in a direction close to or away from the clamping seat 2 to change the distance between the first clamping tooth 6 and the second clamping tooth 7. When the first clamping tooth 6 and the second clamping tooth 7 are close to or meshed with each other, a wiper 8 is clamped. The thickness of the wiper 8 changes the clamping distance between the first clamping tooth 6 and the second clamping tooth 7. The elastic force of the first elastic member 5 keeps the first clamping tooth 6 and the second clamping tooth 7 in a tendency to move close to each other to clamp the wiper 8.

[0040] In this embodiment, the clamping seat 2 is set to be square, and the bottom is roughly flat. The inner side of the first clamping member 3 is movably connected to the clamping seat 2 and can move closer to or away from one of the side edges of the clamping seat 2 to achieve clamping and unfolding. The up and down directions, vertical directions, lateral directions and horizontal directions in this embodiment can refer to Figure 4 direction shown.

[0041] The existing clamping assembly 1 cannot adjust the distance between the clamping teeth, so the tip of the clamping teeth will pierce the wipe 8. When the clamping assembly 1 is unfolded, the wipe 8 is difficult to detach from the clamping teeth, and the wipe 8 needs to be torn off by hand. Or when the wipe 8 is thick, the clamping assembly 1 cannot move to the preset clamping position and lock the position due to the obstruction of the wipe 8, and the thicker wipe 8 cannot be installed. Due to the provision of the elastically retractable first clamping jaw 4, the types of wipes 8 that are suitable for use are more extensive, and the thickness range of the wipe 8 is also larger. The wipe 8 in this embodiment can be a non-woven fabric, wet wipes, paper towels, rags, mops and other soft sheet items. The clamping assembly 1 clamps wipes 8 of different types and thicknesses according to different cleaning needs.

[0042] like Figure 6The first clamping jaw 4 includes a first clamping section 9 and a first telescopic section 10. The first clamping section 9 is provided with a second clamping tooth 7. Each first clamping tooth 6 and each second clamping tooth 7 are arranged along the side of the clamping seat 2. The first clamping section 9 can be guided and installed on the first clamping member 3 so that the first clamping tooth 6 and the second clamping tooth 7 remain parallel when the first clamping jaw 4 moves. Specifically, the first clamping member 3 includes a first sliding section 11 and a first guide groove 12. The first guide groove 12 is fixedly connected to the first sliding section 11 or the first guide groove 12 is arranged on the first sliding section 11. The first guide groove 12 is provided with a first stopper 13. The first telescopic section 10 is provided with a first telescopic hole 14. The first telescopic hole 14 is provided with a second stopper 15. The first stopper 13 is inserted into the first telescopic hole 14 for installation. The first stopper 13 and the second stopper 15 are respectively located on opposite sides of the first telescopic hole 14. The gap between the first stopper 13 and the second stopper 15 is used to install the first elastic member 5. The first sliding section 11 is inserted into the first guide groove 12, and the first sliding section 11 is movably limited by the inner walls of the first guide groove 12. The first telescopic hole 14, the first stopper 13 and the second stopper 15 are arranged, and the first stopper 13 and the second stopper 15 intersect to extend the length of the first elastic member 5 or the telescopic length of the first elastic member 5. The first clamping jaw 4 moves outward to drive the second stopper 15 to move outward to squeeze the first elastic member 5 to change the elastic force.

[0043] It should be noted that, in this embodiment, since the clamping seat 2 is set to a square shape, the first clamping teeth 6 and the second clamping teeth 7 are arranged in a straight line, so the first clamping teeth 6 and the second clamping teeth 7 always remain parallel during the movement. When the clamping seat 2 is set to other shapes, such as when the side of the clamping seat 2 is set to an arc, wave or other shape, the arrangement of the first clamping teeth 6 and the second clamping teeth 7 will also be adjusted accordingly to a shape that is compatible with the arc, wave or other shape, or the first clamping teeth 6 and the second clamping teeth 7 are still arranged in a straight line. When the clamping seat 2 is set to other shapes other than a square, the first clamping teeth 6 and the second clamping teeth 7 remain relatively parallel when the first clamping jaw 4 moves. This relative parallelism can be that the line between any two first clamping teeth 6 and the line between any two second clamping teeth 7 remain parallel.

[0044] The use principle of the clamping assembly 1 in this embodiment is as follows: the first clamping member 3 and the clamping seat 2 have a preset movable stroke and can be positioned after being moved to the position of being expanded and retracted to the end point, such as Figure 1When clamping the wiping object 8, the movable first clamping jaw 4 drives the flat wiping object 8 to roll up and enter the position between the first clamping tooth 6 and the second clamping tooth 7, until the first clamping tooth 6 and the second clamping tooth 7 are staggered and engaged to clamp the wiping object 8. Due to the obstruction of the thickness of the wiping object 8, the first clamping tooth 6 and the second clamping tooth 7 cannot continue to move closer. If the thickness of the wiping object 8 is greater than the preset clamping gap between the first clamping tooth 6 and the second clamping tooth 7, the first clamping member 3 moves to the preset locking position, and the thickness of the wiping object 8 will push the first clamping jaw 4 away from the clamping seat 2, and the elastic force of the first elastic member 5 pulls the first clamping jaw 4 to clamp the wiping object 8.

[0045] According to this principle, the preset clamping gap between the first clamping tooth 6 and the second clamping tooth 7 can be set to the following two types: the first type is, Figure 3 On the lower side, the preset clamping gap between the first clamping tooth 6 and the second clamping tooth 7 is zero, that is, the first clamping tooth 6 and the second clamping tooth 7 are misaligned, fitted or abutted against each other, and the wiping material 8 of any thickness is clamped. The wiping material 8 causes the second clamping jaw 17 to move outward to clamp the wiping material 8. In this way, the elastic force of the first elastic member 5 always increases the tensioning force on the wiping materials 8 of different thicknesses. Even if the first clamping member 3 and the clamping seat 2 are worn or locked, the wiping material 8 can be clamped by the action of the first elastic member 5. The second type is, Figure 3 On the upper side, the preset clamping gap of the first clamping tooth 6 and the second clamping tooth 7 is set to the thickness of conventional paper towels and wet wipes on the market. When clamping thin wiping objects 8 such as paper towels and wet wipes, the first clamping jaw 4 does not move outward, and the first elastic member 5 does not provide a tensioning force. When clamping thick wiping objects 8 such as rags, mops, and multi-layer paper towels, the first clamping jaw 4 moves outward, and the first elastic member 5 provides a tensioning force.

[0046] In the above two methods, the first clamping jaw 4 can adjust the clamping gap between the first clamping teeth 6 and the second clamping teeth 7 according to the thickness of the wipe 8, so that different wipes 8 are clamped stably and will not be pierced or hooked by the clamping assembly 1 and difficult to remove.

[0047] Of course, the range of telescopic activity of the first clamping jaw 4 is determined by the size of the clamping seat 2 and the length of the first telescopic section 10. If the size of the clamping seat 2 is larger, the length of the first telescopic section 10 can be set to be larger, and the thickness range of the wiper 8 that the first clamping jaw 4 can adapt to the telescopic activity is larger.

[0048] In this embodiment, the first elastic member 5 is configured as an elastic member that generates elastic force by compression, such as a compression spring or an elastic block. In other cases, the connection structure between the first telescopic section 10 and the first guide groove 12 can also be adjusted to use an elastic member that generates elastic force by tension, such as a tension spring or a rubber band.

[0049] like Figure 5 and6 In this embodiment, the first sliding section 11 is arranged at the middle of the first clamping member 3, and the first guide groove 12 is arranged at the end of the first clamping member 3. In order to make the elastic force of the first elastic member 5 more balanced, the first guide grooves 12 are arranged at both ends of the first clamping member 3, and the first telescopic sections 10 are arranged at both ends of the first clamping jaw 4. The two groups of first guide grooves 12 and the first telescopic sections 10 are telescopically movable at the same time to make each second clamping tooth 7 move synchronously. The two first guide grooves 12 are fixedly connected by the first connecting beam 16, and the first sliding section 11 is fixedly connected to the first connecting beam 16. The outer end of the first connecting beam 16 is supported by the inner side of the first clamping jaw 4. The symmetrical arrangement of the two groups of first guide grooves 12 and the first telescopic section 10 makes the elastic force of the two first elastic members 5 more balanced, and realizes the first clamping jaw 4 to move inward and outward in a translational manner as a whole. After the first clamping section 9 moves inward to a preset position, it is supported by the first connecting beam 16 to prevent the middle part of the first clamping section 9 from being deformed and bent by the elastic force at both ends.

[0050] Preferably, the first connecting beam 16 is provided with auxiliary teeth (not shown in the figure), which can cooperate with the second clamping teeth 7 to clamp the wiping material 8. The auxiliary teeth can refer to the first clamping teeth 6, and their orientation and usage are similar to the first clamping teeth 6. During the clamping and fixing process, the wiping material 8 is driven by the movement of the first clamping section 9 from the flat unfolded state to move and roll up, and the rolled-up part of the wiping material 8 is clamped by the first clamping teeth 6 and the second clamping teeth 7. The auxiliary teeth are arranged so that when the first clamping jaw 4 moves outward due to the thickness of the wiping material 8, the gap after the movement can be used to clamp the rolled-up top of the wiping material 8 between the second clamping teeth 7 and the auxiliary teeth, so that the clamping of the wiping material 8 is more stable. Example

[0051] like Figure 6-16 A cloth mop comprises a handle 20 and a clamping assembly 1, a clamping seat 2 is provided with an articulated seat 21, a first clamping member 3 and a second clamping member 22, the first clamping member 3 and the second clamping member 22 are respectively movably mounted on opposite sides of the clamping seat 2, the first clamping member 3 is connected to a first connecting rod 23, the second clamping member 22 is connected to a second connecting rod 24, the first connecting rod 23 and the second connecting rod 24 are both rotatably mounted on the articulated seat 21, the articulated seat 21 can move up and down relative to the clamping seat 2, and the clamping At least one guide rod 25 is provided between the seat 2 and the hinge seat 21, and the guide rod 25 prevents the hinge seat 21 from rotating relative to the first connecting rod 23 or the second connecting rod 24. When the wiper 8 is installed, the first clamping member 3 and the second clamping member 22 are in the unfolded state, and the handle 20 or the hinge seat 21 is pressed, and the guide rod 25 guides the hinge seat 21 to move downward in the vertical direction and simultaneously drives the first connecting rod 23 and the second connecting rod 24 to move, so that the first clamping member 3 and the second clamping member 22 move toward each other to clamp the wiper 8.

[0052] like Figure 7 and8 In this embodiment, the clamping seat 2 is rectangular and includes an upper cover 26 and a lower cover 27 , a cavity is formed between the upper cover 26 and the lower cover 27 , and a first clamping member 3 and a second clamping member 22 are formed. The first connecting rod 23 and the second connecting rod 24 are installed in the cavity, and the first clamping member 3 and the second clamping member 22 are installed in the long side direction of the clamping seat 2 to fix the wiping object 8 on the long side of the clamping seat 2. The hinged seat 21 is indirectly installed at the center position of the clamping seat 2 through the first connecting rod 23 and the second connecting rod 24. The lower end of the handle 20 is movably installed at the center position of the hinged seat 21 through the hinge 28. There are two guide rods 25, which are respectively arranged on both sides of the clamping seat 2 relative to the handle 20. When the handle 20 is pressed to install the wiping object 8, the two guide rods 25 can jointly limit and prevent the hinged seat 21 from deflecting relative to the first connecting rod 23 and the second connecting rod 24. In other embodiments, only one guide rod 25 can be set at the center of the hinged seat 21, or four can be set at the corners of the hinged seat 21, or other numbers can be set, so that each guide rod 25 can achieve a stable support and limiting guiding function between the hinged seat 21 and the clamping seat 2.

[0053] It should be noted that the relative movement in the present invention refers to the active movement of one object with reference to another object, the other object being a reference object and assumed to be in a stationary state. For example, the articulated seat 21 in this embodiment can move up and down relative to the clamping seat 2, which means that the articulated seat 21 actively moves up and down relative to the clamping seat 2, and the clamping seat 2 is stationary during the movement. For another example, the guide rod 25 prevents the articulated seat 21 from rotating relative to the first connecting rod 23 or the second connecting rod 24, and the guide rod 25 limits the articulated seat 21 so that it cannot actively rotate relative to the first connecting rod 23 or the second connecting rod 24. The first connecting rod 23 or the second connecting rod 24 remains stationary, and the articulated seat 21 is also stationary or slightly swung due to the assembly gap between the articulated seat 21 and the guide rod 25. On the contrary, when the articulated seat 21 remains stationary, the first connecting rod 23 and the second connecting rod 24 can actively rotate relative to the articulated seat 21.

[0054] In this embodiment, the first clamping member 3 and the second clamping member 22 have the same structure, and only the installation direction is different. Specifically, the second clamping member 22 is further provided with a second clamping jaw 17, and the structure of the second clamping jaw 17 is the same as that of the first clamping jaw 4, and also includes a clamping section and a telescopic section, and is telescopically connected to the second clamping member 22 to tighten the wiping object 8 on the other side through the elastic force of the elastic member. The specific connection structure of the second clamping member 22 and the second clamping jaw 17 is the same as that of the first clamping member 3 and the first clamping jaw 4, and will not be repeated in this embodiment.

[0055] The first connecting rod 23 and the articulated seat 21 rotate along the first axis A, and the second connecting rod 24 and the articulated seat 21 also rotate along the first axis A. The first connecting rod 23 and the second connecting rod 24 can be rotatably connected with the articulated seat 21 at the same position, or can be rotatably connected with the articulated seat 21 at different positions along the first axis A. In this embodiment, the first axis A is set on the vertical plane where the midline of the length direction of the clamping seat 2 is located. The first connecting rod 23 and the second connecting rod 24 are both rotatably set along the first axis A. When the handle 20 or the articulated seat 21 is pressed, The forces applied to the first connecting rod 23 and the second connecting rod 24 are closer, and the activity synchronization of the first connecting rod 23 and the second connecting rod 24 is better. If the first connecting rod 23 and the second connecting rod 24 are arranged in a symmetrical manner with the center line of the clamping seat 2, when the handle 20 and the clamping seat 2 are tilted, when the handle 20 is pressed or when the eccentric position of the hinge seat 21 is pressed, one of the first connecting rod 23 and the second connecting rod 24 is subjected to a large force and the other side is subjected to a small force, and the activity synchronization of the two connecting rods is poor, and the hinge seat 21 may even tilt toward the side with greater force and get stuck.

[0056] In this embodiment, the connection points of the first connecting rod 23, the second connecting rod 24 and the articulated seat 21 are located directly below the connection points of the handle 20 and the articulated seat 21, or there is an overlapping area in the horizontal projection between the connection points of the first connecting rod 23, the second connecting rod 24 and the articulated seat 21 and the connection points of the handle 20 and the articulated seat 21. When the handle 20 is pressed, the force is directly transmitted to the articulated seat 21 and the two connecting rods along the same straight line, the force directions of the two connecting rods are more consistent, and the linkage effect is better.

[0057] Preferably, the size of the hinge seat 21 is smaller than that of the upper cover 26 , and the hinge seat 21 covers the middle position of the upper cover 26 .

[0058] The first connecting rod 23 can be a single connecting rod, whose two ends are connected to the hinge seat 21 and the first clamping member 3, or it can be a connecting rod assembly, that is, the first connecting rod 23 includes two or more movably connected connecting rods, and the two connecting rods located at the ends are respectively connected to the hinge seat 21 and the first clamping member 3. The second connecting rod 24 can also adopt the above-mentioned method. In this embodiment, the first connecting rod 23 and the second connecting rod 24 are both configured as a single connecting rod.

[0059] In the above embodiment, both long sides of the clamping seat 2 are provided with openings, and the first clamping member 3 and the second clamping member 22 can respectively move telescopically inward and outward along the openings. The lower end of the first connecting rod 23 is provided with a second rotating shaft 31 which is rotatably connected to the first sliding section 11, and the second rotating shaft 31 extends along the direction of the second axis B. The second clamping member 22 includes a second sliding section 32, and the lower end of the second connecting rod 24 is provided with a third rotating shaft 34 which is rotatably connected to the second sliding section 32, and the third rotating shaft 34 extends along the direction of the third axis C. Fig.10, the first axis A, the second axis B and the third axis C are all distributed in parallel, and the second axis B and the third axis C are located at symmetrical positions on both sides of the first axis A, the first sliding section 11 and the second sliding section 32 are cross-overlappingly arranged, when the first clamping member 3 and the first connecting rod 23 move, the distance between the first axis A and the first clamping jaw 4 is always greater than the distance between the first axis A and the second clamping jaw 17, when the second clamping member 22 and the second connecting rod 24 move, the distance between the second axis B and the second clamping jaw 17 is always greater than the distance between the second axis B and the first clamping jaw 4, the width of the clamping seat 2 is narrow, and the movable path is limited, the first connecting rod 23, the second connecting rod 24, the first sliding end and the second sliding section 32 require a certain movable stroke, and the first connecting rod 23 and the second connecting rod 24 or the first sliding section 11 and the second sliding section 32 are cross-mounted and movable, which can shorten the movable stroke of each component, that is, there are overlapping sections in the stroke of each component, which is convenient for realizing linkage in the width direction of the clamping seat 2.

[0060] like Fig.11 and 12 , the second axis B and the third axis C are located at the same height, and the distance between them and the first axis A is always the same, the first clamping member 3 and the second clamping member 22 move from the expanded state to the clamped state, the first axis A reduces the height difference with the second axis B or the third axis C, and when the first clamping member 3 and the second clamping member 22 are in the clamped state, the first axis A is located above the second axis B or the third axis C, so that the first connecting rod 23 and the second connecting rod 24 maintain the pre-expanded state, in which the first axis A is slightly higher than the second axis B or the third axis C, so that the first connecting rod The inner sides of the rod 23 and the second connecting rod 24 are slightly arched. If the first axis A, the second axis B and the third axis C are located at the same height, when the clamping member is pulled, the forces between the clamping member and the connecting rod, and between the connecting rod and the hinge seat 21 are on the same plane. The hinge seat 21 and the connecting rod are not subjected to upward force, and it is difficult for both to move or rotate upward. The pre-expansion setting of the first connecting rod 23 and the second connecting rod 24 can transmit force upward when the cloth mop is switched from the clamping state to the expanded state, thereby making the movement of various components of the cleaning tool smoother.

[0061] In this embodiment, a third sliding section 35 is also provided on the first clamping member 3, and a fourth sliding section 36 is also provided on the second clamping member 22. The first sliding section 11 and the second sliding section 32 are stacked up and down, and a second elastic member 37 is connected between the first sliding section 11 and the second sliding section 32. The third sliding section 35 and the fourth sliding section 36 are stacked up and down, and a second elastic member 37 is also connected between the third sliding section 35 and the fourth sliding section 36. The elastic force of the second elastic member 37 can drive the first clamping member 3 and the second clamping member 22 to move synchronously back to back to the unfolded state, or press any one of the first clamping member 3 and the second clamping member 22, and the second elastic member 37 can pull the other clamping member, so that the first clamping member 3 and the second clamping member 22 can move synchronously toward each other to the clamping state. The two clamping members are automatically unfolded by the second elastic member 37. Compared with separately arranging the elastic members, arranging the elastic member between the two clamping members can improve the synchronization between the two clamping members. Even if one of the connecting rods or the clamping members is stuck, the movement of the other connecting rod or the clamping member can be transmitted to the connecting rod or the clamping member through the elastic member to drive its movement, and the activity state of the two clamping members always remains synchronized.

[0062] Specifically, Fig. 9 and 10 The first sliding section 11 and the third sliding section 35 are symmetrically arranged along the first connecting rod 23, and the second sliding section 32 and the fourth sliding section 36 are symmetrically arranged along the second connecting rod 24. The two sides of the first connecting rod 23 are rotatably connected with the first sliding section 11 and the third sliding section 35 respectively, so that a connecting ring is formed between the first clamping member 3 and the first connecting rod 23, and the two sides of the second connecting rod 24 are rotatably connected with the second sliding section 32 and the fourth sliding section 36 respectively, so that a connecting ring is formed between the second clamping member 22 and the second connecting rod 24. During installation, the first sliding section 11 is attached to the top of the second sliding section 32, and the third sliding section 35 is attached to the bottom of the fourth sliding section 36, so that the first clamping member 3, the second clamping member 22, the first connecting rod 23 and the second connecting rod 24 are connected into an integral clamping module. The rotationally symmetrical installation structure of the first clamping member 3 and the second clamping member 22 does not need to be deliberately distinguished between the first clamping member 3 and the second clamping member 22 during production and assembly, that is, after the two first clamping members 3 are installed with each other, the first clamping member 3 and the second clamping member 22 are formed by their relative positions, thereby avoiding the situation where two different clamping members are taken or installed incorrectly, and the assembly efficiency is higher; the first clamping member 3, the second clamping member 22, the first connecting rod 23, and the second connecting rod 24 are cross-connected in the form of two connecting rings, so that the two groups of components form an O-shaped chain, which has a simple structure and can be stably connected even without the assistance of screws or snap-on structures. The components are first installed as an integral clamping module and then installed on the clamping seat 2, which is convenient for assembly on the assembly line and can improve the assembly efficiency of workers.

[0063] In this embodiment, the first sliding section 11 is provided with a first slide 38, and the end of the first slide 38 away from the first clamping section 9 is provided with a first sinker 39 and a first hook 40, the second sliding section 32 is provided with a second slide 41, and one end of the second slide 41 is provided with a second hook 42, the first sinker 39 is inserted into the second slide 41 and can move along the second slide 41, the two ends of the second elastic member 37 are respectively installed on the first hook 40 and the second hook 42, the two ends of the second elastic member 37 are at the same height, and the direction of the elastic force released by the second elastic member 37 is parallel to or on the same straight line with the moving direction of the first sliding section 11 and the second sliding section 32.

[0064] Similarly, the fourth sliding section 36 is provided with a third slide 43, one end of the third slide 43 is provided with a second sinker 44 and a third hook 45, the third sliding section 35 is provided with a fourth slide 46, the end of the fourth slide 46 away from the first clamping section 9 is provided with a fourth hook 47, the second sinker 44 is inserted into the fourth slide 46 and can move along the fourth slide 46, the two ends of the second elastic member 37 are respectively mounted on the third hook 45 and the fourth hook 47, the two ends of the second elastic member 37 are located at the same height, and the direction of the elastic force released by the second elastic member 37 is parallel to or on the same straight line with the moving direction of the third sliding section 35 and the fourth sliding section 36. The direction of the elastic force of the second elastic member 37 is parallel to or on the same straight line with the moving direction of each sliding section, so that the force transmission effect is better, the movement of each sliding section is smoother, and the situation that the inclined elastic force of the second elastic member 37 makes the upper and lower sliding sections fit more tightly and increase friction is avoided. At the same time, a guide track is formed between the sinker and the slide, and each sliding section can move along a preset direction.

[0065] Preferably, the second elastic member 37 is configured as an accessory for releasing elastic force by stretching, such as a tension spring, an elastic belt, an elastic rope, or a rubber band.

[0066] In the above embodiment, a movable hole 48 is provided in the center of the clamping seat 2 which passes through the upper and lower parts, and the first connecting rod 23 and the second connecting rod 24 can move up and down in the movable hole 48. A third sinker 49 is provided on each side of the clamping seat 2 close to the short side, and a guide rod 25 is provided on the third sinker 49. The lower end of the third sinker 49 forms a first track 50. The first clamping member 3 and the second clamping member 22 can move along the first track 50 close to each other, and the first track 50 limits the up and down movement of the first clamping member 3 and the second clamping member 22. In other embodiments, the third sinker 49 can also be provided on only one of the first clamping member 3 and the second clamping member 22. Any one of the first clamping member 3 and the second clamping member 22 moves along the first track 50 to indirectly drive the other clamping member to move along the direction of the first track 50. The first track 50 limits the up and down movement of any one clamping member, thereby indirectly limiting the up and down movement of the other clamping member.

[0067] The clamping seat 2 is provided with a support column 51 on each side close to the long side, and a second track 52 is provided on the side of the support column 51. The first connecting rod 23 and the second connecting rod 24 are provided with a clearance hole at the position corresponding to the support column 51. The second rotating shaft 31 and the third rotating shaft 34 enter the second track 52 for movement, and the second track 52 limits the up and down movement of the second rotating shaft 31 and the third rotating shaft 34. In other embodiments, only one support column 51 can be provided on one side, and the support seat cooperates with any one of the connecting rods to limit the position, so that any one of the rotating shafts enters the second track 52 for movement.

[0068] Preferably, the third sinker 49 and the support column 51 are fixedly arranged at the lower end of the upper cover 26 and abut against the upper end of the lower cover 27. The third sinker 49 and the support column 51 jointly play a supporting role to prevent the upper cover 26 or the lower cover 27 from deforming toward the middle cavity.

[0069] In the above embodiment, a switch assembly is also provided on the clamping seat 2, and the switch assembly includes a button 53 and a spring. The button 53 can be installed on the hinge seat 21 so as to be laterally movable. A hook 54 is provided at the lower end of the button 53, and a socket for the hook 54 to pass through is provided on the clamping seat 2. The hinge seat 21 and the hook 54 move down to a low position, and the hook 54 can enter the socket downward to cooperate with the clamping seat 2 to limit the position so as to prevent the hinge seat 21 from moving upward. By pressing the button 53, the hook 54 releases the limit, and the second elastic member 37 releases the elastic force to make the hinge seat 21, the first clamping member 3, the second clamping member 22, the first connecting rod 23 and the second connecting rod 24 automatically move to the unfolded state.

[0070] Preferably, a spring is provided between the button 53 and the hinge seat 21, and the elastic force of the spring keeps the button 53 in an outwardly extended state. In this state, the hook 54 cooperates with the clamping seat 2 for positioning. The clamping seat 2 is provided with a guide surface 55 at the edge of the socket. When the hinge seat 21 and the button 53 move downward and pass the socket position, the hook 54 abuts against the guide surface 55. While the hook 54 moves along the guide surface 55, the button 53 overcomes the elastic force of the spring and moves inward, so that the hook 54 passes through the socket and cooperates with the clamping seat 2 for positioning.

[0071] The following describes the steps and principles of using the cloth-clamped cleaning tool of the present invention: When the wiper 8 needs to be removed, the button 53 is pressed and moved inward, the hook 54 and the clamping seat 2 are released from the limit, the elastic member releases the elastic force to pull the first clamping member 3 and the second clamping member 22 to move backwards at the same time, and the first clamping member 3 and the second clamping member 22 drive the lower ends of the first pull rod and the second pull rod to move toward each other and rotate through the second rotating shaft 31 and the third rotating shaft 34, and the upper ends of the first pull rod and the second pull rod move upward and rotate, driving the hinged seat 21 and the handle 20 to move to a high position. At the end of the movement, the first clamping member 3 and the second clamping member 22 extend from the side of the clamping seat 2, the first clamping tooth 6 and the second clamping tooth 7 move away, and the wiper 8 is removed from the clamping seat 2.

[0072] When installing the wiper 8, the wiper 8 is spread flat on the ground, the handle 20 is lifted to align the clamping seat 2 with the position of the wiper 8, the hinged seat 21 is pressed downward or the handle 20 is rotated to an angle roughly perpendicular to the clamping seat 2 and the handle 20 is pressed. The hinged seat 21 moves vertically downward under the limiting and guiding action of the guide rod 25, and drives the first connecting rod 23 and the second connecting rod 24 to move downward and rotate outward. The lower ends of the first connecting rod 23 and the second connecting rod 24 respectively push the first clamping member 3 and the second clamping member 22 to overcome the elastic force of the second elastic member 37 and move toward each other. The first clamping tooth 6 and the second clamping tooth 7 are close to each other, and the hook 54 is against the guide surface 55. The hook 54 moves along the guide surface 55 to make the button 53 move inward to overcome the elastic force of the spring, so that the hook 54 passes through the insertion hole and cooperates with the clamping seat 2 for positioning. At this time, the first clamping tooth 6 and the second clamping tooth 7 are in a cross-engaged position and clamp the two sides of the wiper 8, and the installation of the wiper 8 is completed.

[0073] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
