Description

Technical Field

[0001] The utility model relates to the field of daily necessities, in particular to a mop clamping device. Background Art

[0002] Mops are a widely used cleaning tool. However, since mops are often wet after cleaning, how to position them is a major problem. People usually place the mop cloth on the ground and the mop handle against the wall. However, this method does not allow the mop to dry easily and easily breeds bacteria. Alternatively, people may hang the mop from a nail on the wall. Although this method solves the problem of bacteria breeding on the mop cloth, it damages the wall surface and is not aesthetically pleasing, which does not meet people's usage requirements. There are also some mop clamps on the market that can effectively save indoor space by placing the mop vertically. However, these clamps are generally fixed to the wall with double-sided tape or strong glue. However, after the glue ages and becomes brittle, the mop clamp easily falls off, and the glue left on the wall is difficult to clean, which affects the re-fixing and installation of the mop clamp. In addition, the clamping portion of the mop clamp is usually exposed, which affects the appearance of the product and is easily damaged. In addition, these clamps are fixed to the wall with double-sided tape, which is very inconvenient to remove. Utility Model Content

DETAILED DESCRIPTION

[0036] The present invention will be further described below with reference to the accompanying drawings:

[0037] like Figures 1 to 12As shown, a mop clamping device includes a mop clamp 1, which is fixedly connected to a base plate 2. A top cover 3 is connected to the front side of the base plate 2. The top cover 3 is provided with a cavity for accommodating the mop clamp 1, and a notch 31 is provided on the front side of the top cover 3, corresponding to the clamping space 11 of the mop clamp 1. A receiving portion 21 is provided on the back side of the base plate 2, and a suction cup 4 is connected to the receiving portion 21. The mop clamp 1 is fixed to the wall via the suction cup 4. In this way, the top cover 3 covers the structure of the mop clamp 1 to provide protection and prevent the clamping arm from being exposed, thereby slowing the aging and brittleness of the mop clamp 1 structure and extending the service life of the mop clamp 1. At the same time, the mop clamp is fixed to the wall via the suction cup, which allows for easy movement and change of the installation position. The operation is simple and convenient and will not damage the wall.

[0038] In a preferred case, the mop clip 1 has two elastic clamping arms 5 for clamping the mop rod, and a clamping space 11 of the mop clip 1 is formed between the two elastic clamping arms 5; one end of the two elastic clamping arms 5 is fixedly connected to the bottom plate 2 and the other ends are close to each other to form a clamping opening 12. The mop rod is squeezed from the clamping opening 12 to one side of the clamping space 11, passes through the clamping opening 12 and reaches the clamping space 11, and the elastic clamping arms 5 clamp the mop rod to prevent the mop from falling downward. The width of the clamping opening is 10-30 mm, that is, the size of the clamping opening can be adjusted. The width of the clamping opening can be any value of 10mm, 11mm, 12mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 23mm, 25mm, 28mm, 29mm, or 30mm, or the width of the clamping opening can be any two values ​​from 16-30mm as endpoint values, for example, 10-20mm, 16-30mm, 18-28mm, 20-28mm, etc.; in this way, mop rods of different sizes can be clamped.

[0039] Furthermore, rollers 6 are provided on both sides of the clamping opening 12; a hinged seat 52 is provided on the side of the elastic clamping arm 5 near the clamping opening 11, and pivots 61 are provided at the upper and lower ends of the roller 6. The pivots 61 are rotatably connected within the hinged seat 52. Thus, when the mop rod passes through the clamping opening 12, the rollers 6 rotate accordingly, allowing the mop rod to easily enter the clamping space. Furthermore, the mop clamp 1 also includes an elastic fastening plate 7, which is preferably made of silicone or rubber. The fastening plate 7 is arranged between the roller 5 and the base plate 2 and is parallel to the base plate 2. After the mop rod enters the clamping space 11, the fastening plate 7 presses the mop rod outward, thereby squeezing the mop rod between the elastic clamping arm 5 and the fastening plate 7, thereby more stably fixing the mop rod. Hanging holes 71 are provided at both ends of the fastening piece 7, and hooks 51 that cooperate with the hanging holes 71 are provided on the outer side of the elastic clamping arm 5. The two ends of the fastening piece 7 pass through between the roller 6 and the elastic clamping arm 5 and are fixed on the hooks 51. In this way, the distance between the fastening piece 7 and the roller 6 is relatively small, and the fastening piece 7 has a greater squeezing force on the mop rod, making the mop rod less likely to fall off.

[0040] In a preferred embodiment, a scented wood 81 is provided next to the mop clip 1. When air cleanser or perfume is poured onto the scented wood 81, the scented wood 81 absorbs the air and then slowly releases the air, which has the effect of refreshing the air and purifying odors. A downward notch is provided on the upper surface of the scented wood to store the scented liquid so that the scented wood 81 can fully absorb the scented liquid and volatilize the fragrance for a long time. Compared with placing a separate aromatherapy bottle in the bathroom, it saves space and avoids the problem of the aromatherapy bottle being bumped or broken. Furthermore, a placement groove 8 is fixedly connected to the bottom plate 2, and the scented wood 81 is placed in the placement groove 8. An opening 32 corresponding to the placement groove 8 is provided on the upper cover 3 to facilitate the addition of scented liquid to the scented wood 81.

[0041] In a preferred case, a latch tongue 33 is provided inside the upper cover 3, and a slot 22 cooperating with the latch tongue 33 is provided on the bottom plate 2, and the upper cover 3 is snap-fitted and fixed to the bottom plate 2; a fixing plate 1 34 and a fixing plate 2 35 are also provided inside the upper cover 3, and the bottom plate 2 is fixed between the fixing plate 1 34 and the fixing plate 2 35. Furthermore, the side of the fixing plate 2 35 close to the bottom plate 2 is a guide slope, which facilitates the snapping of the bottom plate 2 between the fixing plate 1 34 and the fixing plate 35.

[0042] In a preferred case, the suction cup 4 includes a skeleton 9, a connecting portion 91 is provided on the upper part of the skeleton 9, an elastic colloid 10 is coated on the skeleton 9, and the lower surface of the elastic colloid 10 forms an adsorption cavity 41 which is deep in the middle and shallow on all sides. The middle part of the adsorption cavity 41 is the top surface 42, and the edge of the top surface 42 gradually expands outward and downward to form the side wall 43 of the adsorption cavity 41. A first edge portion 20 is surrounded at one end of the side wall 43 away from the top surface 42, and the bottom surface of the first edge portion 20 is inclined toward the upper surface of the elastic colloid 10, and a first turning line 201 is formed between the first edge portion 20 and the side wall 43. The first turning line 201 is placed against the wall 30, and the elastic colloid 10 is then squeezed through the connecting portion 91, expelling the air in the adsorption chamber 41, thereby adsorbing the elastic colloid 10 against the wall 30. At this point, the skeleton 9 and the elastic colloid 10 have a contraction force that restores their deformation, squeezing the sidewall 43 toward the wall 30 and adhering to it, thereby tightly adsorbing the elastic colloid 10 against the wall 30. After the suction cup hangs an item, the first edge portion 20 prevents the outer edge of the sidewall 43 from curling, thereby ensuring that the suction cup maintains strong adsorption capabilities even after prolonged use.

[0043] In a preferred case, a joint 44 is formed between the top surface 42 and the side wall 43, and the joint 44 is a second turning line or arc transition surface formed between the top surface 42 and the side wall 43 of the adsorption chamber 41; the top surface 42 is a plane or an arc surface, and preferably the top surface 42 is a plane parallel to the wall surface 30.

[0044] In a preferred case, the range of the angle α between the first edge portion 20 and the wall surface 30 is 1°≤α≤74°, such as the angle α can be any one of 1.0°, 2.0°, 2.2°, 3.0°, 3.5°, 4.0°, 5.5°, 6.8°, 7.2°, 8.4°, 9.5°, 10.0°, 12.5°, 15.2°, 16.7°, 17.3°, 27.5°, 28.5°, 29.0°, 30.0°, 31.2°, 34.0°, 40.0°, 50.0°, 62.0°, and 74.0°; the range of the angle β between the side wall 43 and the wall surface 330 is 5°≤β≤20°, such as the angle β can be 5.0°, 5.1°, 6.2°, 7.0°, 7.2°, 8.0 any angle among °, 8.4°, 9.5°, 10.6°, 11.0°, 12.5°, 13.5°, 14.0°, 15.0°, 16°, 16.7°, 17.3°, 18.0°, 18.5°, 19.0°, and 20.0°; the width of the side wall 43 is d1, the width of the first edge portion 20 is d2, 0.01≤d2 / d1≤0.3, that is, d2 / d1 can be any value among 0.01, 0.02, 0.03, 0.04, 0.06, 0.07, 0.08, 0.11, 0.12, 0.13, 0.14, 0.15, 0.16, 0.17, 0.18, 0.19, 0.20, 0.21, 0.28, 0.29, and 0.30.

[0045] In a preferred embodiment, the side portion of the lower surface of the elastic colloid 10 is formed by splicing together a plurality of first inclined surfaces 101, preferably four first inclined surfaces 101. Adjacent first inclined surfaces 101 are connected by arc transitions to form sidewalls 43. This allows the elastic colloid 10 to fit more closely to the wall 30, allowing air in the adsorption chamber 4 to be more thoroughly discharged. The outer edge of the lower surface of the elastic colloid 10 is cut obliquely upward to form a first edge portion 20.

[0046] In a preferred embodiment, the skeleton 9 is in the shape of a bowl with a high center and low sides. An annular protrusion 93 and several strip-shaped protrusions 92 are provided on the outer edge of the skeleton 9. The strip-shaped protrusions 92 are evenly arranged on the skeleton 9 around the circumference. The strip-shaped protrusions 92 can extend radially or be arc-shaped and bend in the same direction. The annular protrusion 93 penetrates and connects the strip-shaped protrusions 92, thereby increasing the strength of the skeleton 1 and strengthening the connection between the elastic colloid 10 and the skeleton 9, thereby preventing the elastic colloid 10 from falling off the skeleton 9. Several strip-shaped holes 94 are provided between the connecting portion 91 and the annular protrusion 93. Several strip-shaped slits 95 are provided on the edge of the skeleton 9. The strip-shaped slits 95 and the strip-shaped holes 94 can extend radially or be arc-shaped and bend in the same direction. The strip-shaped slits 95 are evenly arranged on the edge of the skeleton 1 around the circumference, and the strip-shaped holes 94 are evenly arranged on the skeleton around the circumference. The provision of the strip-shaped slits 95 and the strip-shaped holes 94 makes deformation of the skeleton 1 more convenient and labor-saving.

[0047] In a preferred embodiment, the receiving portion 21 is snap-connected or screw-connected to the connecting portion 91; a boss 96 is provided in the middle of the frame 9, and the connecting portion 91 is disposed on the upper surface of the boss 96. Furthermore, the connecting portion 91 is a hollow connecting block 97, on which a protruding snapping edge 98 is provided. The receiving portion 21 is provided with a snapping groove 23 that matches the shape of the connecting block 97, and a retaining edge 24 is provided within the snapping groove 23. When the snapping groove 23 is aligned with the connecting block 97 and pressed, the snapping edge 98 deforms through the snapping groove 23, reaches the retaining edge 24, and then recovers its deformation and clamps onto the retaining edge 24, thereby securing the mop clip to the suction cup. Furthermore, the snapping groove 23 is a through hole, and the connecting block 97 protrudes from the upper surface of the base plate 2. This shortens the distance between the mop clip and the wall, making the mop clip more secure.

[0048] In a preferred embodiment, the base plate 2 is fixedly connected to a plurality of mop clips 11, which are arranged in a horizontal sequence, preferably four in number, so that multiple mops or brooms can be clamped, making the overall space more tidy. Furthermore, the back side of the base plate 2 is provided with at least two receiving portions 21 connected to the suction cups 4, which can increase the load-bearing capacity of the mop clips and prevent them from falling.

[0049] In the above embodiment, after attaching the suction cup to the wall at a suitable location, the engaging groove 23 is aligned with the connecting block 97 and pressed so that the engaging edge 98 engages the limiting edge 24, thereby completing the concealed rotation and fixation of the mop clamp. The mop rod is then squeezed inward from between the two rollers 6 at the notch 31. After passing through the rollers 6, the mop rod enters the clamping space 11 and contacts the fastening piece 7. The fastening piece 7 squeezes the mop rod between the fastening piece and the roller, thereby clamping the mop rod and preventing it from falling. During use, the mop rod is grasped and pulled outward, and the mop rod is released from between the two rollers 6 for sanitary cleaning. The scented wood 6 slowly releases the scented liquid to purify the air.
