Description

Technical Field

[0001] The utility model relates to a cleaning tool, in particular to a connecting structure of a cotton swab mop head. Background Art

[0002] At present, there are mainly two ways for the water squeezing mechanism of a cotton swab mop. One is folding water squeezing, and the other is squeezing water. In the folding water squeezing method, two mounting plates are symmetrically arranged above the cotton swab head. The cotton swab head is detachably mounted on the water squeezing clamping plate of the mop through the mounting plates. During installation, the cotton swab head is squeezed from both ends to the middle, so that the two mounting plates on the cotton swab head move towards the middle. Then, the tongue of the mounting plate is aligned with the card slot on the water squeezing clamping plate. After the tongue is in place, the tongue is expanded towards both ends by the tension of the cotton swab head to achieve clamping. Since there is no locking mechanism for the detachable structure between the existing mounting plate and the water squeezing clamping plate, when the cotton swab head is axially stressed and squeezed, the mounting plate moves axially, and there is a phenomenon that one side of the mounting plate is separated from the water squeezing clamping plate, thus affecting the use effect. Content of the Utility Model

[0003] The purpose of the utility model is to provide a connecting structure of a cotton swab mop head. The mounting plate and the water squeezing clamping plate adopt a clamping structure with a locking mechanism. During installation, it is not necessary to squeeze the cotton swab head from both sides to the middle, and it has the characteristics of convenient installation and reliable connecting structure.

[0004] To achieve the above purpose, the following technical solutions are adopted:

[0005] A connecting structure of a cotton swab mop head includes a cotton swab head 2, a mop handle 1 and a water squeezing mechanism. The water squeezing mechanism includes a water squeezing seat 31, water squeezing clamping plates 32 and a connecting seat 33. The water squeezing seat 31 is fixedly connected to the lower end of the mop handle 1. Two water squeezing clamping plates 32 are respectively hinged on both sides of the connecting seat 33. The two water squeezing clamping plates 32 are respectively hinged to the water squeezing seat 31 through connecting rods. The connecting seat 33 is connected to the mop handle 1 through a water squeezing driving mechanism 4. Two mounting plates 5 are arranged at the top of the cotton swab head 2. The mounting plates 5 are mounted on the corresponding water squeezing clamping plates 32 through a detachable clamping structure. The characteristics are as follows: The detachable clamping structure includes a plurality of upwardly protruding tongues 51 and an upwardly protruding elastic locking piece 52 arranged at the top of the mounting plate 5. A card slot 61 is arranged at the position of the water squeezing clamping plate 32 corresponding to the tongue 51, and a locking slot 62 is arranged at the position of the water squeezing clamping plate 32 corresponding to the elastic locking piece.

[0017] As Figures 1-3 shown, a connecting structure of a cotton swab mop head includes a cotton swab head 2, a mop handle 1 and a water squeezing mechanism. The water squeezing mechanism includes a water squeezing seat 31, water squeezing clamping plates 32 and a connecting seat 33. The water squeezing seat 31 is fixedly connected to the lower end of the mop handle 1. Two water squeezing clamping plates 32 are respectively hinged on both sides of the connecting seat 33. The two water squeezing clamping plates 32 are respectively hinged to the water squeezing seat 31 through connecting rods. The connecting seat 33 is connected to the mop handle 1 through a water squeezing driving mechanism 4. Two mounting plates 5 are provided at the top of the cotton swab head 2. The mounting plates 5 are installed on the corresponding water squeezing clamping plates 32 through a detachable clamping structure.

[0018] The detachable clamping structure includes a plurality of upwardly protruding tongues 51 provided at the top of the mounting plate 5 and upwardly protruding elastic locking pieces 52 provided on the front and rear sides of the mounting plate 5. A hollow portion 53 is provided between the inner side and one end of the elastic locking piece 52 and the mounting plate. A card slot 61 is provided at the position corresponding to the tongue 51 on the water squeezing clamping plate 32. A lock groove 62 is provided on the front and rear side walls of the water squeezing clamping plate 32 corresponding to the elastic locking piece. When the mounting plate 5 is clamped with the water squeezing clamping plate 32, the tongue 51 is inserted into the card slot 61, and the front and rear elastic locking pieces 52 are accommodated in the lock groove 62. The card slot 61 includes a mutually communicating inlet slot 611 and a clamping slot 612. The clamping slots 612 of the card slots on the two water squeezing clamping plates 32 are all located on the same side of the inlet slot 611. The lock groove 62 includes an inlet 621 and a locking groove 622 located on one side of the inlet. Both the inlet 621 and the locking groove 622 are grooves that penetrate the water squeezing clamping plate from bottom to top. The inlet 621 and the locking groove 622 are transitioned through a locking step 623. A transition inclined surface is provided between the locking step and the inlet. The locking grooves 622 of the lock grooves on the two water squeezing clamping plates 32 are all located on the same side of the inlet 621. When the elastic locking piece 52 corresponds to the inlet 621, the tongue 51 just corresponds to the inlet slot 611. When the elastic locking piece 52 corresponds to the locking groove 622, the tongue 51 just corresponds to the clamping slot 612. When the mounting plate 5 is clamped on the water squeezing clamping plate 32, the upper end of the elastic locking piece 52 is slightly higher than the top surface of the water squeezing clamping plate 32.

[0019] When assembling the present utility model, the elastic locking pieces 52 on both sides are made to correspond to the inlet 621, and the tongues 51 correspond to the inlet slots 611. Then, the cotton swab head 2 and the water squeezing clamping plate 32 are brought together, so that the tongues 51 enter the inlet slots 611, and the elastic locking pieces 52 are inserted into the inlets 621 to clamp the water squeezing clamping plate 32 from both sides;

[0020] Then, the mop head 2 is axially moved relative to the wringing splint 32. Since there is a hollow setting 53 between the inner side and one end of the elastic locking piece 52 and the mounting plate, the two outer expansions of the elastic locking piece 52 smoothly pass through the locking step 623 and enter the locking groove 622. At this time, the tongue 51 also enters the clamping groove opening 612. The buckle at the end of the tongue 51 hooks the upper edge of the clamping groove opening 612 to limit the up-and-down position of the mop head 2. At the same time, the tongue 51 and the clamping groove opening 612 limit the front-and-back position of the mop head. The elastic locking piece 52 is blocked by the locking step 623 and locked in the locking groove 622, thereby limiting the axial position of the mop head. The axial, front-and-back, and up-and-down positions are all restricted, so that the mop head is locked, which has the characteristics of convenient installation and reliable connection structure.

[0021] When the mop head needs to be disassembled, since the upper end of the elastic locking piece 52 is slightly higher than the top surface of the wringing splint 32, the elastic locking piece 52 can be easily bent outward with a little force. At this time, the axial movement of the mop head causes the tongue to retract from the clamping groove opening 612 back into the entry groove 611, and then the mop head can be easily removed from the wringing splint 32.

[0022] As Figure 3 、 4 shown, the entry port 621 of the locking groove 62 of the present utility model is an inclined surface opened at the lower edge of the side wall of the wringing splint 32, and an inclined surface 54 is provided on the inner side of the upper end of the elastic locking piece 52 for cooperation. This structure is simpler and the assembly is also convenient.

[0023] In the present utility model, due to the elastic locking pieces and locking grooves which are arranged on the front and back sides of the mounting plate and the wringing splint and cooperate with each other, the positional relationship between the entry groove opening and the clamping groove opening of the mop head clamping grooves on the left and right sides is kept consistent, and there is no need for symmetrical setting. The tongue of the mop head can be inserted into the clamping groove and pushed to one side, which makes the installation more convenient. Due to the additional locking structure, there is no need to worry about the problem of the mop head falling off during use.
