Further, the positioning structure includes a locking screw, which is threadedly connected to the handle rod, and one end of the locking screw is in contact with the telescopic rod.

Further, the handle bar, telescopic bar, fixed plate and movable plate are all aluminum alloy parts.

Further, the bristles include soft bristles and hard bristles with different hardness, and the soft bristles and hard bristles are arranged separately.

The beneficial effects of the present invention are: the retractable toilet brush provided by the present invention can expand the brush head of the toilet brush by changing the distance between the movable plate and the fixed plate, and then change the outer diameter of the brush head to adapt to The bristles on the brush head are divided into hard bristles and soft bristles according to the aperture requirements of different sewage outlets.

Detailed ways

As shown in Figures 1 to 9, the present invention includes a hand-held rod 1, a handle 2, a fixed plate 3, a movable plate 4, an expansion keel 5, a bristle keel 6, a bristle 61, a telescopic rod 7 and a handle 71. The figures describe the invention.

As shown in Figure 1, the hand-held rod 1 is the main body of the present invention, which can be made of aluminum alloy, stainless steel or plastic material. A handle 2 is provided at the rear end of the hand-held rod, and a rubber sleeve is provided on the handle to increase the grip. Comfort when gripping. The handle is provided with a hollow hole 21 to facilitate hanging. The front end of the hand-held rod is a hollow structure, as shown in Figure 7, a spring 8 is arranged in the inner chamber of the hand-held rod, and the installation end of the spring is fixed on the inner chamber wall of the hand-held rod. The front end of the hand-held rod is provided with a long hole 11, the long hole runs through the outer wall of the hand-held rod, and the front end of the hand-held rod is also provided with some positioning holes 12 arranged in parallel, and one end of the positioning hole communicates with the long hole. A telescopic rod 7 is slidably installed in the inner cavity of the hand-held rod, and a handle 71 is provided on the outer wall of the telescopic rod. Sliding horizontally, when the handle is placed in a certain positioning hole, the relative position of the telescopic rod and the handle rod is fixed. The handle is T-shaped, and the handle and the telescopic rod are axially vertically arranged, and the handle can be integrally formed with the telescopic rod. One end of the telescopic rod is fixedly connected with the spring, and changing the relative position of the telescopic rod and the handle rod can realize the extension or contraction of the spring. A movable plate 4 is fixedly installed on the free end of the telescopic rod, and the movable plate is circular and can be a stainless steel part, an aluminum alloy part or a plastic part. A fixed plate 3 is fixedly installed at the front end of the hand-held bar, and the fixed plate is an annular stainless steel part, an aluminum alloy part or a plastic part, and the telescopic rod passes the circular hole of the fixed plate and extends to the side where the movable plate is at. As shown in Figure 4, a number of expansion keels 5 evenly arranged along the circumferential direction are arranged between the fixed plate and the movable plate. The movable plate is fixedly connected, and when the movable plate moves to the side where the fixed plate is located, it will press the expansion keel to change from a straight line to an arc shape, and the middle part of each expansion keel protrudes to the side away from the telescopic rod. The expansion keel has elasticity, and when the movable plate is away from the fixed plate, as shown in Figure 5, the expansion keel will return to its original shape under the action of its own elasticity.

As shown in Figure 3, a number of bristle keels 6 located at the periphery of the expansion keel are also provided between the fixed plate and the movable plate. to expand the number of keels. The bristles 61 are fixed on the bristle keel, and the bristles are densely arranged on the bristle keel. The bristles are used to rub against the toilet for cleaning. In order to increase the cleaning effect, the bristles are divided into two types, namely soft bristles and hard bristles. The two kinds of bristles have different hardness. As shown in Figure 9, the soft bristles with low The stiff bristles are separated from each other. When the handle is located in the lowermost positioning hole, the expansion keels and the bristle keels are in a natural state. At this time, some expansion keels form a cylindrical shape, and some bristle keels enclose another cylindrical shape. As shown in Figure 2, when the telescopic rod is moved upward so that the handle is placed in the upper positioning hole, the expansion keel and the bristle keel can be compressed into an arc shape under pressure. At this time, the entire toilet brush is in a working state and can be used For cleaning the sewage outlet. According to the hole diameter of the sewage outlet, the adjustment handle is placed in different positioning holes, which can change the compression degree of the expansion keel and the bristle keel, so as to change the outer diameter of the brush head. At this time, the bristles can be in close contact with the inner wall of the sewage outlet to Ensure the friction between the bristles and the inner wall of the sewage outlet. The arrangement of the expansion keel is to provide internal support for the bristle keel, so as to avoid the large deformation of the bristle keel caused by the extrusion between the bristle keel and the sewage outlet.

The positioning hole, the elongated hole and the handle constitute a positioning structure for realizing relative fixing between the telescopic rod and the handle rod. The positioning structure can also be a locking screw, which is threadedly connected with the hand-held rod, and one end of the locking screw is pressed against the telescopic rod to realize relative fixing of the two.
