Referring to fig. 5 and 6, the connection structure of the embodiment of the present invention is used in a cleaning device C which can automatically move for cleaning as shown in the figure, and the cleaning device C is provided with:
a body C1 movable on a work surface F;
a driving unit C2 disposed on the main body C1 for driving the main body C1 to move automatically on the working surface F for advancing, retreating, rotating …, etc.;
a cleaning unit C3 disposed on the body C1 for cleaning the working surface F when the body C1 moves; the cleaning unit C3 has a cleaning assembly C31, such as a brush plate, a driver C32, such as a motor, and a drive shaft C33 for transmitting power from the driver; one side of the transmission shaft C33 is provided with a key part C331; wherein, the connecting seat A is arranged on the cleaning component C31; one end of the transmission shaft C33 can be embedded into the pivot hole B15 of the connection shaft B, so that the connection shaft B is arranged on the transmission shaft C33, the driver C32 outputs rotating power which is transmitted to the connection shaft B through the transmission shaft C33 and drives the connecting seat A to drive the cleaning component C31 to rotate so as to clean the working surface F;
a control unit C4, installed on the main body C1, for executing various data operations and various function controls of the cleaning device C.
In practice, when the user wants to mount the cleaning assembly C31 on the cleaning device C, the user can pick up the connecting seat a with one hand, align the insertion hole a4 with the connecting shaft B, and move the connecting seat a upward toward the connecting shaft B, so that the connecting shaft B axially passes through the insertion hole a 4;
with the upward movement of the connecting seat A, the connecting shaft B sequentially passes through the meshing hole A21, the second through hole A31 and the through hole A16 from top to bottom, so that the meshing piece B2 above the connecting shaft B can axially pass through the meshing hole A21 of the connecting seat A to be meshed with the meshing hole A21 of the connecting seat A in a concave-convex manner so as to limit the movement in the horizontal direction, and when the connecting shaft B rotates, the connecting shaft B can drive the connecting seat A to rotate and cannot idle relative to the connecting seat A;
when the cone part B14 below the connecting shaft B axially passes through the second through hole a31 of the stopper A3, the cone part B14 will touch the stopper a32 at one end of the second through hole a31, so that the stopper a32 slides upwards along the conical surface of the cone part B14, and meanwhile, the stopper A3 is resisted to displace radially towards the first direction, and the elastic element a35 is compressed to accumulate the elastic restoring force of the elastic element a 35;
after the cone part B14 below the connecting shaft B axially passes through the second through hole A31 of the stopper A3, the stopper A32 continues to slide upwards along the outer edge of the stopper B13;
after the stopping portion B13 of the connecting shaft B axially passes through the second through hole a31 of the stopping member A3, the stopping portion a32 reaches the position of the leaning portion B12, and because the outer diameter of the leaning portion B12 is smaller than that of the stopping portion B13, the compression of the elastic element a35 can be extended, so that the stopping member A3 radially returns to displace toward the second direction by the elastic restoring force of the elastic element a35, the stopping portion a32 moves to the upper side of the stopping surface B131 of the stopping portion B13, and the concave surface a321 of the stopping portion a32 presses against the leaning portion B12;
after the stopping portion a32 moves to the upper side of the stopping surface B131, the hand of the user can release the connecting seat a to stop the upward movement of the connecting seat a, at this time, the connecting seat a will move downward due to gravity, so that the stopping member A3 on the connecting seat a also moves downward, as shown in fig. 7, since the stopping portion B13 is located below the stopping member A3, when the stopping member A3 moves downward, the stopping portion a32 of the stopping member A3 will contact the stopping surface B131 of the stopping portion B13 to limit the movement in the vertical direction, thereby limiting the return displacement of the connecting shaft B in the axial direction, and the stopping portion B13 can support the stopping member A3 to limit the connecting seat a from continuing to move downward, so that the connecting seat a is kept on the connecting shaft B;
on the contrary, when the user wants to detach the cleaning assembly C31 from the cleaning device C, as shown in fig. 8, the user only needs to press the pressing portion a36 of the stopper A3 to make the stopper A3 move radially in the first direction, so that the stopper a32 is separated from the upper side of the stopping surface B131, the support of the stopper A3 by the stopping portion B13 is released, and the connecting seat a is kept moving downward without any stop when moving downward due to gravity, and moves to separate from the connecting shaft B.
According to the connecting method, the connecting structure and the cleaning device using the connecting structure, a user only needs to enable the connecting shaft B to axially penetrate through the embedding hole A4 of the connecting seat A, the radial displacement of the stop piece A3 can be used for selectively enabling the stop piece A3 to be stopped by the stop part B13, the return displacement of the connecting shaft B in the axial direction is selectively limited, the connecting seat A can be kept on the connecting shaft B or separated from the connecting shaft B, and the use is quite simple and convenient.
The above description is only a preferred embodiment of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made in the claims and the description of the present invention are within the scope of the present invention.
