Description

Technical Field

[0001] This utility model belongs to the field of mop technology, and in particular relates to a cloth-clamping mop. Background Technology

[0002] Flat mops are common household cleaning tools, mainly consisting of a mop handle and a mop head for wiping floors. A wiping cloth, usually flat, is attached to the bottom of the mop head. Clip-on mops are a type of flat mop, and some on the market currently feature a clip-on cloth function.

[0003] For example, Chinese Patent Application No. 202322533280.6 discloses a simple mop head structure for a flat mop with a cloth clamp, including an upper cover, a first telescopic plate, a second telescopic plate, an elastic element, and a base plate; the first telescopic plate and the second telescopic plate are each provided with an action part extending from the upper end face of the upper cover, a sliding part located between the upper cover and the base plate, and a clamping part located on one side of the base plate; the elastic element connects the sliding part of the first telescopic plate and the second telescopic plate, and the elastic element elastically acts to make the clamping part of the first telescopic plate and the clamping part of the second telescopic plate fit against the side of the base plate.

[0004] In the aforementioned patent usage, the user squeezes the actuating parts of the first and second telescopic plates with both hands to open the clamping part. Releasing the clamping parts then allows for clamping. However, the device lacks a locking mechanism, leading to some operational inconveniences: maintaining the open clamping part requires continuous squeezing of the actuating parts, necessitating one hand to hold the actuating part while the other adjusts the cleaning cloth position, making it impossible to flatten the cloth with both hands, which is cumbersome. Replacing the cleaning cloth requires multiple attempts at alignment, each adjustment necessitating squeezing the button again, increasing operation time. Furthermore, the clamping part rebounds too quickly during use, posing a certain risk, especially when the user is in a hurry, potentially pinching their hand while adjusting the cleaning cloth; squeezing the actuating parts can also cause finger pain, particularly noticeable for users with weaker strength (such as the elderly or children) or those with hand discomfort. Utility Model Content

[0005] To address the shortcomings of existing technologies, a cloth-clamping mop that can lock the clamping part is provided.

[0006] This utility model is achieved by the following technical solution: a cloth-clamping mop, comprising:

[0007] substrate;

[0008] Two sets of clamping mechanisms are symmetrically arranged on both sides of the substrate. Each set includes a plate body that slides inside the substrate. One end of the plate body extends to the outside of the substrate and is provided with a clamping part for clamping a cleaning cloth. The plate body is also provided with a first toothed rack that extends along the sliding direction of the plate body.

[0009] The gear is rotatably disposed within the base plate and meshes between two first racks, and can drive the first racks to slide, so that the clamping part can perform clamping or releasing movements.

[0010] A driving component is used to drive the clamping part to perform a releasing motion. It includes a driving part located inside the substrate and a pressing part located outside the substrate. The driving part is provided with a second rack that meshes with a gear. The driving part can slide in the horizontal direction to drive the gear to rotate.

[0011] The first elastic element is used to realize the resetting and clamping movement of the clamping part; and

[0012] The locking mechanism includes a locking part, an unlocking part, and a second elastic member that are linked together. The locking part is located on the sliding path of the driving part and is located at the lower end of the driving part. A first wedge-shaped locking protrusion and a slot are provided between the two to achieve locking between them. When the driving part slides to the locking area of ​​the locking part, the second elastic member applies an upward reset force to the locking part and the unlocking part, causing the first wedge-shaped locking protrusion to engage in the slot. The unlocking part is located on the outside of the base plate. When the unlocking part is pressed down, the first wedge-shaped locking protrusion disengages from the slot.

[0013] In use, the user first presses the pressing part, causing the driving part to slide horizontally. The second rack of the driving part drives the gear to rotate, which in turn causes the first rack to slide. The sliding of the first rack causes the plates on both sides to move outward, thus releasing the clamping part of the clamping mechanism. Simultaneously, the driving part slides to the locking area of ​​the locking part. The inclined surface of the first wedge-shaped locking protrusion creates a vertical distance between the driving part and the locking part, causing the first wedge-shaped locking protrusion to gradually slide into the slot. Then, the second elastic element applies an upward reset force to the locking and unlocking parts, thus locking the first wedge-shaped locking protrusion with the slot. At this point, the driving part cannot reset, thus maintaining the released state of the clamping part. The user can then adjust the position of the cleaning cloth with both hands, and then press the unlocking part, creating a vertical distance between the locking part and the driving part, causing the first wedge-shaped locking protrusion and the slot to separate. At this point, the reset force of the first elastic element causes the clamping part to clamp tightly, and the driving part resets and retracts, moving away from the locking area of ​​the locking part.

[0014] The first elastic element can apply a reset elastic force to the driving element and / or the plate, thereby enabling the clamping part to perform clamping motion.

[0015] This design incorporates a locking mechanism, allowing users to maintain the clamping part in a relaxed state simply by pressing the pressing part. At this time, users can adjust the position, angle, or flatten the cleaning cloth with both hands. Then, a single press of the unlocking part unlocks the cloth, allowing the clamping part to grip it securely. This simplifies use, eliminates the need for continuous pressing of the pressing part, reduces finger strain, and enhances safety.

[0016] Preferably, the first wedge-shaped locking protrusion is disposed at the lower end of the driving part, and the slot is disposed in the locking area of ​​the locking part; or

[0017] The slot is located at the lower end of the drive unit, and the first wedge-shaped locking protrusion is located in the locking area of ​​the locking unit; or

[0018] The first wedge-shaped locking protrusion is disposed at the lower end of the drive part, and the locking area of ​​the locking part is provided with an upwardly extending second wedge-shaped locking protrusion, and the second wedge-shaped locking protrusion and the surface of the locking part enclose and form the slot.

[0019] A second wedge-shaped locking protrusion is provided on the locking area of ​​the locking part, so that the inclined surfaces of the first wedge-shaped locking protrusion and the second wedge-shaped locking protrusion can contact each other, making it easy for the driving part and the locking part to move away from each other in the vertical direction when the driving part slides to the locking area.

[0020] Preferably, the number of the second wedge-shaped locking protrusions is at least two, and they are spaced apart along the sliding direction of the drive part, and the first wedge-shaped locking protrusion can selectively abut against a certain second wedge-shaped locking protrusion.

[0021] By providing at least two second wedge-shaped locking protrusions, the first wedge-shaped locking protrusion can selectively abut against a certain second wedge-shaped locking protrusion, allowing the clamping part to be locked in different release positions. This gives the locking mechanism multiple adjustable positions, making it suitable for different users. For example, the elderly or children with less strength can lock the clamping part at the first position, while men or those with greater strength can press the second or third position.

[0022] Preferably, the upper side of the base plate is provided with a hinge seat for connecting the connector of the mop handle, and the unlocking part is provided in the hinge seat. The unlocking part has an insertion groove for the hinge shaft to be inserted, so that the unlocking part can be hingedly connected to the connector of the mop handle.

[0023] By placing the unlocking part inside the hinge seat, and by hingedly connecting the unlocking part to the joint of the mop handle, the mop handle can be directly pressed when the unlocking part is pressed, thereby unlocking the mop. This makes it more convenient for users and also makes the structure more compact.

[0024] Preferably, the unlocking part is provided with a downwardly extending rotating shaft, on which the gear is rotatably connected, and the second elastic member is disposed at the lower end of the gear, with both ends of the second elastic member abutting against the inner wall of the gear and the base plate, respectively.

[0025] The above-mentioned arrangement can optimize the position of the gears, make the structure more compact, and allow the substrate to be made thinner overall.

[0026] Preferably, the drive unit is hollowed out and has a frame structure, the unlocking part is located inside the frame structure, the drive unit has a downward-opening through groove, and the locking part extends from the unlocking part side to the through groove side and passes through the through groove.

[0027] A through slot is provided on the drive unit so that the locking part passes through the slot. This method can reduce the space occupied by both in the vertical direction, thereby making the entire substrate thinner and allowing the mop to clean narrow areas better.

[0028] Preferably, one of the hinge seats is provided with a lateral opening in the horizontal direction and forms a cavity between it and the upper side wall of the substrate, allowing the pressing part to move. The first elastic member is disposed in the cavity and applies a force to the pressing part.

[0029] By setting the pressing part on the hinge seat of the handle for hinged mops, the structure is more compact. The first elastic element is set in the hinge seat to apply force to the pressing part, so that the pressing part can move in the opposite direction of the pressing direction, thereby allowing the driving part to slide in the opposite direction, causing the gear to rotate in the opposite direction, thereby enabling the first rack to slide in the opposite direction, thereby indirectly applying force to the clamping mechanism, causing the clamping part to perform clamping movement.

[0030] Preferably, the pressing part is provided with a guide hole for the first elastic element to extend into, and the cavity is also provided with a guide post for the first elastic element to be fitted.

[0031] The guide hole and guide post ensure that the first elastic element does not shift during elastic expansion and contraction.

[0032] Preferably, the plate is provided with hooks, and the first elastic element connects two hooks, the first elastic element applying a force that brings the plate closer together; or

[0033] The plate body is provided with a mating groove extending along the sliding direction of the plate body. The first elastic member is provided in the mating groove. One end of the first elastic member abuts against the inner wall of the substrate, and the other end abuts against the groove wall of the mating groove, so as to apply a force to bring the plate body closer together.

[0034] The above two methods enable the elastic element to directly apply force to the plate of the clamping mechanism in order to achieve the purpose of clamping movement of the clamping part.

[0035] Preferably, the first rack is provided with a guide groove extending along the sliding direction of the plate, and both plates are provided with guide strips that extend into the guide grooves of the first rack of the other plate, and the guide grooves and guide strips are slidably engaged.

[0036] The cooperation of guide grooves and guide bars allows the two plates to be mutually constrained during sliding, ensuring the accuracy of the two clamping mechanisms when clamping or releasing.

[0037] Compared with existing technologies, the advantages of this invention are as follows: This solution, through the setting of a locking mechanism, allows the user to maintain the loosened state of the clamping part simply by pressing the pressing part. At this time, the user can adjust the position, angle, or flatten the cleaning cloth with both hands. Then, simply pressing the unlocking part unlocks the cloth, allowing the clamping part to perform a clamping motion, thereby tightening the cleaning cloth. This makes it simpler to use, eliminating the need for continuous pressing of the pressing part, reducing finger strain, and increasing safety. Attached Figure Description

[0054] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0055] Example 1

[0056] like Figure 1 As shown, this embodiment 1 discloses a cloth-clamped mop, which includes a base plate 1. The base plate 1 is rectangular. The upper side of the base plate 1 is an upper side wall 11. The wall at the center of the upper side wall 11 is raised upward to form a raised portion 111. Two hinge seats 2 are provided on the raised portion 111 at intervals. The two hinge seats 2 can be hinged to the joint 100 of the mop handle through the hinge shaft 712.

[0057] like Figure 6 , Figure 7 , Figures 9 to 12As shown, two sets of clamping mechanisms are provided on the two symmetrical long sides of the substrate 1. The clamping mechanism includes a plate 4 slidably disposed inside the substrate 1. The plate 4 extends along the width direction of the substrate 1 and slides along the width direction. One end of the plate 4 extends to the outside of the substrate 1 and is provided with a clamping part for clamping a cleaning cloth. The clamping part is a first clamping tooth 41 extending along the long side wall of the substrate 1. A second clamping tooth 13 is provided on the long side wall of the substrate 1 to engage with the first clamping tooth 41. The lower end of the first clamping tooth 41 protrudes from the lower surface of the substrate 1.

[0058] The plate 4 is also provided with a first rack 45 extending along its sliding direction. A gear 5 is also rotatably connected at the center of the substrate 1. The gear 5 is located between the two first racks 45 and meshes with the two first racks 45 for transmission. When the gear 5 rotates, it can drive the first racks 45 to slide along the width direction of the substrate 1, so as to realize the movement of the first clamping teeth 41 moving away from or closer to each other, thereby achieving the effect of loosening or clamping.

[0059] A driving member 3 is also provided on the substrate 1. The driving member 3 includes a driving part 32 located inside the substrate 1 and a pressing part 31 located outside the substrate 1. The driving part 32 has a rectangular sheet-like frame structure. A second rack 321 that meshes with the gear 5 is provided on one side wall inside the frame. The second rack 321 is located above the first rack 45. The gear 5 has an axial thickness, so it can mesh with the first rack 45 and the second rack 321 at different height positions. The pressing part 31 is used to be pressed by a horizontal force to drive the driving part 32 to slide, thereby driving the gear 5 to rotate, so that the plate 4 moves outward from the substrate 1 to realize the release movement of the first clamping tooth 41. The pressing and sliding trajectory of the pressing part 31 is along the length direction of the substrate 1.

[0060] A first elastic element 33 is also provided within the substrate 1. The first elastic element 33 can directly or indirectly apply force to the clamping mechanism, causing the first clamping teeth 41 to perform clamping movement. The first elastic element 33 is disposed between two plates 4, and the two plates 4 are provided with two sets of mutually cooperating hooks 42. The two ends of the first elastic element 33 are hooked onto the hooks 42. The first elastic element 33 is a tension spring, which can pull the plates 4 on both sides inward to make the plates 4 move closer to each other, thereby causing the first clamping teeth 41 to perform clamping movement.

[0061] like Figures 1 to 5 As shown, a locking mechanism is also provided on the substrate 1. The locking mechanism includes a locking part 72, an unlocking part 71, and a second elastic member 8 that are linked together. The locking part 72 and the unlocking part 71 are integrally formed. The unlocking part 71 is located inside the frame structure of the driving part 32. The left side of the driving part 32 is provided with a downward-opening through groove 322. The locking part 72 extends in a strip shape from the unlocking part 71 toward the through groove side 322 and passes through the through groove 322.

[0062] The locking part 72 is located on the sliding path of the driving part 32. The locking part 72 is located at the lower end of the driving part 32. The through groove 322 is provided with a first wedge-shaped locking protrusion 91 extending downward. In the locking area of ​​the locking part 72, there are two second wedge-shaped locking protrusions 92 extending upward. The two second wedge-shaped locking protrusions 92 are spaced apart along the sliding direction of the driving part 32, and the two second wedge-shaped locking protrusions 92 and the surface of the locking part 72 enclose each other to form an upwardly opening slot 93.

[0063] When the drive unit 32 slides to the locking area of ​​the locking unit 72, the first wedge-shaped locking protrusion 91 abuts against the second wedge-shaped locking protrusion 92 on the right, increasing the distance between the drive unit 32 and the locking unit 72, allowing the first wedge-shaped locking protrusion 91 to pass over the second wedge-shaped locking protrusion 92 on the right. Then, the second elastic member 8 applies an upward reset force to the locking unit 72, causing the first wedge-shaped locking protrusion 91 to engage in the slot 93, and abut against the second wedge-shaped locking protrusion 92 on the right. At this time, the drive unit 32 cannot reset, thus maintaining the released state of the first clamping tooth 41.

[0064] If the user continues to push the pressing part 31, the driving part 32 can continue to slide to the second wedge-shaped locking protrusion 92 on the left, and the first wedge-shaped locking protrusion 91 can abut against the second wedge-shaped locking protrusion 92 on the left after passing it. This achieves the disengaged state of the first clamping tooth 41 in the second position. At this time, the opening size of the first clamping tooth 41 is larger.

[0065] When the user presses down on the unlocking part 71, the distance between the locking part 72 and the driving part 32 increases, allowing the first wedge-shaped locking protrusion 91 to disengage from the obstruction of the second wedge-shaped locking protrusion 92. At this time, the driving part 32 is reset under the action of the first elastic member 33, causing the first clamping tooth 41 to perform a clamping movement.

[0066] like Figures 1 to 5 As shown, the hinge seat 2 has a hollow chamber 21, and the unlocking part 71 is provided in the hinge seat 2. It has an insertion groove 711 for the hinge shaft 712 to be inserted, so that the unlocking part 71 can be rotatably connected to the joint 100 of the mop handle.

[0067] The lower end of the unlocking part 71 is provided with a downwardly extending rotating shaft 51. The gear 5 is located below the unlocking part 71 and is rotatably connected to the rotating shaft 51. The second elastic member 8 is provided at the lower end of the gear 5 and the two ends of the second elastic member 8 respectively abut against the gear 5 and the lower inner wall of the base plate 1.

[0068] The unlocking part 71 is provided with a guide post 331 extending toward the pressing part 31. The guide post 331 is located inside the chamber 21. A first elastic member 33 is also provided inside the chamber 21, and one end of the first elastic member 33 is sleeved on the guide post 331. The pressing part 31 is provided with a guide hole 311 opening toward the guide post 331, and the other end of the first elastic member 33 extends into the guide hole 311.

[0069] like Figure 8 As shown, or two sets of mating grooves 44 extending along the sliding direction are provided on the plate 4. A first elastic element 33 is provided in the mating groove 44. The first elastic element 33 is a compression spring. One end of the first elastic element 33 abuts against the groove wall at one end of the mating groove 44, and the other end of the first elastic element 33 abuts against the inner wall of the substrate 1, so that an elastic force is applied to the plate 4 to move inward toward the substrate 1, so that the plates 4 on both sides can be brought inward, thereby realizing that the plates 4 move closer to each other, thereby making the first clamping tooth 41 perform a clamping movement.

[0070] In actual production, the first elastic element 33 can be set separately in the hinge seat 2 or set separately on the plate 4 or between the plates 4; or the first elastic element 33 can be set simultaneously in the hinge seat 2 and between or on the plates 4. All three design methods can realize the clamping movement of the first clamping tooth 41.

[0071] like Figure 6 As shown, the substrate 1 has a first groove 12 extending along the sliding direction of the plate 4 on both sides. The side wall of the plate 4 contacts and engages with the groove wall of the first groove 12, so that the plate 4 and the first groove 12 are slidably engaged.

[0072] like Figures 9 to 11 As shown, the first rack 45 is provided with a guide groove 451 extending along the sliding direction of the plate 4, and both plates 4 are provided with guide bars 46 extending into the guide groove 451 of the first rack 45 of the other plate 4, and the guide groove 451 and the guide bar 46 are slidably engaged.

[0073] like Figure 1 and Figure 13 As shown, the raised portion 111 rises upward so that the upper side wall 11 forms a groove 6. The groove wall of the groove 6 is provided with a number of evenly spaced limiting protrusions 61. The limiting protrusions 61 can limit the up and down position of the drive portion 32, so that the limiting protrusions 61 and the groove 6 form a second sliding groove. The second sliding groove extends along the pressing direction of the pressing portion 31, and the drive portion 32 slides in the second sliding groove.

[0074] Example 2

[0075] like Figure 14As shown, the difference between Embodiment 2 and Embodiment 1 is that the locking part 72 does not have a second wedge-shaped locking protrusion 92, but instead has an upward-opening slot 93 directly formed on the wall of the locking part 72. This design can also lock the driving part 32 with the locking part 72.

[0076] Example 3

[0077] like Figure 15 As shown, the difference between Embodiment 3 and Embodiment 1 is that: a downwardly opening slot 93 is provided at the lower end of the driving part 32, and an upwardly extending first wedge-shaped locking protrusion 91 is provided in the locking area of ​​the locking part 72. This design can also achieve the locking part 72 locking the driving part 32.

[0078] In use, the user first presses the pressing part 31, causing the driving part 32 to slide horizontally. The second rack 321 of the driving part 32 drives the gear 5 to rotate. When the gear 5 rotates, it drives the first rack 45 to slide. The sliding of the first rack 45 causes the plates 4 on both sides to move outward, causing the first clamping tooth 41 of the clamping mechanism to release. At the same time, the driving part 32 slides to the locking area of ​​the locking part 72. The inclined surface of the first wedge-shaped locking protrusion 91 contacts the inclined surface of the second wedge-shaped locking protrusion 92, creating a distance between the driving part 32 and the locking part 72 in the vertical direction, allowing it to pass over the second wedge-shaped locking protrusion 92 on the right. Then, the second elastic member 8 applies an upward reset force to the locking part 72, allowing the first wedge-shaped locking protrusion 91 to engage in the slot 93, and the first wedge-shaped locking protrusion 91 to abut against the second wedge-shaped locking protrusion 92 on the right. At this time, the driving part 32 cannot reset, thus maintaining the released state of the first clamping tooth 41.

[0079] At this time, the user can adjust the position of the cleaning cloth with both hands, and then press the mop handle to make the unlocking part 71 drop, so that the locking part 72 and the driving part 32 are separated in the vertical direction, so that the first wedge-shaped locking protrusion 91 is disengaged from the abutment state of the second wedge-shaped locking protrusion 92. At this time, the reset elastic force of the first elastic member 33 will cause the first clamping tooth 41 to clamp, and the driving part 32 will reset and retract, moving away from the locking area of ​​the locking part 72.
