Description

Technical Field

[0001] The present application relates to the technical field of cleaning tools, and in particular to a swimming pool cleaning brush with adjustable angle. Background Art

[0002] In the daily maintenance and cleaning of swimming pools, the importance of pool cleaning brushes as a core tool is self-evident. Especially when facing the corners, edges and uneven bottom areas of the swimming pool, traditional fixed-angle cleaning brushes often perform poorly because they cannot adapt to changing cleaning needs, and may even damage the surface of the swimming pool. In order to solve this problem, a variety of cleaning brushes with adjustable angles have emerged on the market.

[0003] Among them, the cleaning brush described in Chinese patent announcement number CN219894957U provides users with a convenient operating experience with its unique angle adjustment structure and clamping structure design. The user only needs to turn the handle to drive the rotating rod to rotate through the transmission of the worm and the worm wheel, thereby realizing flexible adjustment of the angle of the connecting block, thereby meeting the multi-angle cleaning needs of the medicine cabinet or other cleaning objects.

[0004] However, in scenarios where the brush needs to withstand greater resistance, such as pool cleaning, the design of this cleaning brush also exposes some problems. Because the connection structure between the worm gear and the worm gear may not be stable enough when subjected to greater pressure, it is easy to lose teeth, which not only affects the cleaning efficiency, but also may shorten the service life of the cleaning brush.

[0005] The above contents are only used to assist in understanding the technical solution of the present application, and do not constitute an admission that the above contents are the closest prior art to the present application. Summary of the invention

[0008] In some embodiments, a shaft is provided at the axis center of the worm wheel, the shaft passes through the second connecting part and is rotatably connected to the first connecting part, the second connecting part and the shaft are fixedly connected, and the worm wheel and the shaft are fixedly connected.

[0009] In some embodiments, the worm screw passes through the handle, is disposed in the first groove and meshes with the worm wheel, and a knob is fixedly disposed at one end of the worm screw.

[0010] In some embodiments, the sliding plate is slidably disposed in the mounting groove, and a second groove for accommodating the dial button is provided on a side wall of the mounting groove.

[0011] In some embodiments, there are two locking rods, which are symmetrically distributed on one surface of the sliding plate. A spring is installed on the other surface of the sliding plate, and the other end of the spring is fixed to the second connecting portion.

[0012] In some embodiments, the sliding plate and the dial button are rotationally connected via a damping shaft, and the dial button can be placed in the second groove to temporarily fix the locking mechanism.

[0013] In some embodiments, the first connecting portion is in an arc shape, and a plurality of locking holes are symmetrically provided on the arc, and the diameter of the locking holes matches the diameter of the locking rod for cooperative locking.

[0014] The beneficial effects of the present application are: the angle adjustment function of the handle and the brush is achieved through a worm gear, and the connection between the handle and the brush head is further strengthened by a locking mechanism installed in the mounting groove, and the locking mechanism is temporarily fixed by a button that can be offset in the second groove, which is simple to operate and has a stable structure.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to achieve. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that the combination of such technical solutions does not exist and is not within the scope of protection of this application.

[0027] In the embodiments of this application, please refer to Figure 1-9 As shown, the angle-adjustable swimming pool cleaning brush mainly comprises: a handle 1, one end of which is provided with a first connecting portion 2 and a first groove 3 for holding operation; a brush head 4, on which is provided a second connecting portion 5, and the first connecting portion 2 and the second connecting portion 5 are hinged; an adjusting mechanism, including a worm gear 6 and a worm 7, for adjusting the angle between the handle 1 and the brush head 4; a locking mechanism, which is arranged in a mounting groove 14 opened on the second connecting portion 5, and includes a sliding plate 8, a locking rod 9, a dial button 10 and a spring 11, for locking or unlocking the handle 1 and the brush head 4.

[0028] Some preferred / improved embodiments based on the above embodiments will be described below. Any one of the following embodiments may be selected, or multiple embodiments may be selected and combined.

[0029] like Figure 1-3As shown, a shaft 12 is provided at the axis center of the worm wheel 6, the shaft 12 passes through the second connecting part 5 and is rotatably connected to the first connecting part 2, the second connecting part 5 and the shaft 12 are fixedly connected, the worm wheel 6 and the shaft 12 are fixedly connected, and when the knob 13 is rotated, the worm 7 rotates synchronously and drives the shaft 12 to rotate, and the rotation of the shaft 12 drives the second connecting part 5 fixed on the shaft 12 to achieve angle adjustment of the brush head 4.

[0030] Specifically, the worm 7 passes through the handle 1 and is disposed in the first groove 3 and meshes with the worm wheel 6. A knob 13 is fixedly disposed at one end of the worm 7. The knob 13 is disposed to facilitate the rotation of the worm 7 and facilitate operation.

[0031] like Figure 4-5 As shown, the sliding plate 8 is slidably disposed in the mounting groove 14 , and a second groove 15 for accommodating the dial button 10 is provided on a side wall of the mounting groove 14 .

[0032] Furthermore, there are two locking rods 9 symmetrically distributed on one surface of the sliding plate 8. A spring 11 is installed on the other surface of the sliding plate 8. The other end of the spring 11 is fixed on the second connecting portion 5 for resetting the locking mechanism.

[0033] like Figure 5-6 As shown, the sliding plate 8 and the dial button 10 are rotationally connected via a damping shaft 16, which is used to slow down the rotation speed between the sliding plate 8 and the dial button 10 and maintain the stability of the components in a specific position. The dial button 10 can be placed in the second groove 15 to temporarily fix the locking mechanism.

[0034] like Figure 7 As shown, the first connecting portion 2 is in an arc shape, and a plurality of locking holes 17 are symmetrically opened on the arc. The diameter of the locking hole 17 matches the diameter of the locking rod 9 , and locking is achieved by inserting the locking rod 9 into the locking hole 17 .

[0035] like Figure 7-9 As shown, when the spring 11 is not compressed, under the limiting action of the spring 11, the locking mechanism is inserted into the first connecting part 2 to achieve locking. When the angle needs to be adjusted for cleaning, the locking mechanism needs to be toggled to disengage from the first connecting part 2, and then the dial button 10 is rotated at the position of the second groove 15 and placed in the second groove 15 to achieve temporary fixation of the locking mechanism. Then the knob 13 is rotated to adjust the adjustment mechanism. After reaching the specified position angle, the dial button 10 is adjusted to drive the sliding plate 8 to move under the reaction force of the spring 11, and then the locking rod 9 is driven to move and insert into the locking hole 17, thereby locking the handle 1 and the brush head 4 at this angle.
