Detailed Description

The following describes the embodiments of the present invention in detail. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

In the present invention, the use of the terms of orientation such as "upper and lower" in the case where no description is made to the contrary generally means the orientation in the assembled and used state. "inner and outer" refer to the inner and outer contours of the respective component itself.

The utility model provides a reciprocating type reversing mechanism of straight line, as shown in fig. 1 and fig. 2, this reciprocating type reversing mechanism of straight line, including two sets of switching-over subassemblies, switching-over groove 2, switching-over shifting block 3 and pole 4, two sets of switching-over subassembly bilateral symmetry sets up and all is located switching-over groove 2 is interior, switching-over shifting block 3 is located two sets of between the switching-over subassembly, the switching-over subassembly can be along under the drive of external force the axis direction motion of pole 4 is in order to stir in turn switching-over shifting block 3. Specifically, the reversing assembly comprises a spring block hook 11, a spring block 12, a compression spring 13, a stop 14 and a tension spring 15; the elastic block 12, the compression spring 13 and the stop block 14 are all sleeved on the rod 4 and can move along the axial direction of the rod 4; the compression spring 13 is positioned between the elastic block 12 and the stop block 14, one end of the compression spring is connected with the elastic block 12, and the other end of the compression spring is connected with the stop block 14; one end of the tension spring 15 is connected with the elastic block hook 11, and the other end of the tension spring is connected with the reversing groove 2.

Preferably, the spring block hook 11 is hinged to the reversing slot 2, the tension spring 15 is connected to the hook portion of the spring block hook 11, and the tension spring 15 has a tendency that the spring block hook 11 hooks the spring block 12. In this way, the movement of the tension spring 15 and the latch hook 11 provides a certain resistance. The outer side of the hook part of the elastic block hook 11 is provided with an inclined plane 7 which is used for preventing the elastic block hook 11 from stopping the reset of the elastic block 12.

Further, the linear reciprocating reversing mechanism also comprises a driving mechanism 5 for driving the linear reciprocating reversing mechanism. Preferably, the drive mechanism 5 is a hydraulic cylinder. The piston rod of the hydraulic cylinder is fixedly connected with the stopper 14. In this way, the stop 14 can move with the piston rod of the hydraulic cylinder.

The utility model discloses a theory of operation: as shown in fig. 1 and 2, when the hydraulic cylinder drives the stopper 14 to move, the spring block 12 cannot move to the right due to the restriction of the spring block hook 11, and the compression spring 13 therebetween is compressed. When the stop 14 continues to move to the right until contacting the elastic block hook 11 and pushing it, the elastic block hook 11 will release the restriction on the elastic block 12, so that the elastic block is ejected by the compression spring 13 and pushes the reversing block 3 to shift to the right to complete the reversing. Because the reversing valve 6 is connected with the hydraulic cylinder, after the reversing assembly on the left side reverses the reversing valve 6, a piston rod of the hydraulic cylinder moves in the opposite direction, namely moves leftwards, the elastic block 12 is pulled leftwards to reset, and meanwhile, the reversing assembly on the right side reverses according to the steps to shift the reversing shifting block 3 leftwards. The steps are alternately carried out in such a way, and the direction is changed in a circulating way. Then the linear motion of the hydraulic cylinder is converted into rotary motion through a power conversion mechanism, and then the brush head of the pot brushing device is connected, so that the brush head of the pot brushing device can rotate in a variable direction, and the pot brushing is cleaner. The above-mentioned "left" and "right" refer to the orientations in the state of fig. 1 and 2.

The power conversion mechanism can adopt a simple gear and rack structure, and the brush head of the pot brushing device adopts the common brush head of the pot brushing device on the market. Because the innovative part of the utility model is not in the power conversion mechanism and the brush head, and both belong to the prior art, the specific structure is not described herein again.

The above detailed description describes the preferred embodiments of the present invention, but the present invention is not limited to the details of the above embodiments, and the technical idea of the present invention can be within the scope of the present invention, and can be right to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.

It should be noted that the various features described in the above embodiments may be combined in any suitable manner without departing from the scope of the invention. In order to avoid unnecessary repetition, the present invention does not separately describe various possible combinations.

In addition, various embodiments of the present invention can be combined arbitrarily, and the disclosed content should be regarded as the present invention as long as it does not violate the idea of the present invention.
