Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following describes the car wash brush of this utility model in detail with reference to the embodiments and accompanying drawings.

[0024] <Example>

[0025] This embodiment proposes a car wash brush 10, which includes a handle 1 and a base 2. The bottom of the base 2 is used to install a cleaning cloth or cleaning brush, and the middle is provided with a handle shaft 25 for installing the handle 2. A connecting rod 26 is inserted into the bottom of the handle shaft 25. A pair of mounting sleeves 27 are formed on the top of the base 2 for inserting the two ends of the connecting rod 26. The handle shaft 25 is disposed between the two mounting sleeves 27 through the connecting rod 26.

[0026] The handle has a first connecting seat 11 at the end near the handle shaft 25, and a second connecting seat 21 at the end of the handle shaft 25 near the handle 1. Figure 1 The first connecting seat 11 and the second connecting seat 21 are both annular and correspond to each other. They can be folded together by an adjustment component. The first connecting seat 11 can be rotated and folded relative to the second connecting seat 21 to adjust the angle between the handle 1 and the base 2 for user convenience.

[0027] like Figure 2 and Figure 3 As shown, the adjustment assembly includes a knob 3, a rotating component 4, and a locking component 5. The rotating component 4 is fixed to the knob 3, and the locking component 5 is sleeved on the outer periphery of the rotating component 4, and has a locked state and an unlocked state. When the locking component 5 is in the locked state, the first connecting seat 11 and the second connecting seat 21 are fixed together by the locking component 5. When the locking component 5 is in the unlocked state, the first connecting seat 11 and the second connecting seat 21 can rotate relative to each other. The rotating component 4 can be made of metal.

[0028] The rotating part 4 has an external thread 41 on its outer circumference, and the locking part 5 has an internal thread 51 that matches the external thread 41 on its inner side. Through the screw connection of the internal and external threads, the locking part 5 can move relative to the rotating part 4 when the rotating part 4 rotates. The outer side of the locking part 5 is provided with several connecting keys 52, the inner side of the first connecting seat 11 is provided with several first keyways 12, and the inner side of the second connecting seat 21 is provided with several second keyways 22. When in the locked state, one end of the connecting key 52 is embedded in the first keyway 12, and the other end is embedded in the second keyway 22 (e.g., ...). Figure 3 (as shown); when in the unlocked state, the connection key 52 leaves the first key slot 12 or the second key slot 22 (in this embodiment, it is in the unlocked state when it leaves the second key slot 22).

[0029] As shown in the figure, in this embodiment, the knob 3 is mounted on the first connecting seat 11. By rotating the knob 3, the knob 3 rotates along with the rotating component 4, which in turn drives the locking component 5 to move axially. When the locking component 5 moves toward the side where the connecting seat 11 is located, the connecting key 52 gradually leaves the second keyway 22. When the connecting key 52 completely leaves the second keyway 22, it is in the unlocked state. At this time, the handle 1 can rotate and fold relative to the base 2. After rotating to a certain angle, the other second keyway 22 can be aligned with the connecting key 52. ​​At this time, rotating the knob 3 in the opposite direction will drive the locking component 5 to move in the opposite direction until the connecting key 52 moves into the second keyway 22, which will change to the locked state. At this time, the handle 1 can be fixed relative to the base 2. Therefore, the locking component 5 can be switched between the locked and unlocked states simply by rotating the knob 3. This method of using keyways and connecting keys in combination to achieve locking and unlocking avoids the handle from rotating relative to the base due to accidental touch when the knob is in the locked state, thus ensuring that it can be stably kept in the locked state.

[0030] like Figure 6As shown, the end of the connecting key 52 (the end facing the second keyway 22 in this embodiment) has a first guide slope 53, and the side of the first keyway 12 or the second keyway 22 (the second keyway 22 in this embodiment) facing the connecting key 52 has a second guide slope 23 that cooperates with the first guide slope 53. The setting of the two guide slopes can make the connecting key 52 enter more smoothly.

[0031] In this embodiment, the car wash brush 10 also includes a fastener 6, and a knob 3 is disposed on the first connecting seat 11, such as... Figure 2 and Figure 3 As shown, fastener 6 is mounted on the second connecting seat 21. One end of fastener 6 passes through the rotating member 4 and is inserted into the knob 3, while the other end is mounted on the second connecting seat 21 via a washer 61. Specifically, a mounting seat 24 is formed in the middle of the second connecting seat 21 protruding towards the first connecting seat 11. A recessed groove 241 is formed on the outer side of the mounting seat 24. One end of the rotating member 4 is inserted into the mounting seat 24, and the other end is for the knob 3 to be inserted. Fastener 6 is mounted on the recessed groove 241 of the mounting seat 24 via the washer 61. This allows the knob 3 to be stably mounted on the first connecting seat 11, preventing the knob 3 from falling off and enhancing stability. In this embodiment, fastener 6 can be a bolt, which can be directly tightened with a screwdriver to achieve installation with the knob 3.

[0032] The knob 3 is rotatably mounted on the outside of the first connecting seat 11, with a rotating shaft 31 formed in the middle. The rotating part 4 has an insertion hole 42 for the rotating shaft 31 to be inserted on the side facing the knob 3. Several limiting strips 32 are formed on the outer periphery of the rotating shaft 31, and a limiting groove 43 for the limiting strips 32 to be embedded in the inner wall of the insertion hole 42. The cooperation between the limiting strips 32 and the limiting grooves 43 enables the knob 3 to form a firm connection with the rotating part 4, so that the rotating part 4 can be driven to rotate synchronously when the knob 3 rotates, thereby strengthening the connection and tightness between the knob 3 and the rotating part 4.

[0033] The above embodiments are merely illustrative of specific implementations of the present invention, and the present invention is not limited to the scope of the above embodiments. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents. For example, in the above embodiments, the knob 3 is disposed on the first connecting seat 11; in actual situations, the knob 3 can also be mounted on the second connecting seat 21.
