Description
Technical field
The utility model relates to floor-cleaning machine technical field more particularly to a kind of control switch structures for floor-cleaning machine.
Background technique
Currently, the control handle of floor-cleaning machine is generally two, the two sides of floor-cleaning machine handle are placed in, operator is using
When, it usually wants two hands to mediate two control handles to start machine together, makes machine operation.It, can if controlling handle to loosen
It causes floor-cleaning machine flame-out, can not work on.The hand of operator cannot rest always in this way, operator easy to increase
Labor intensity.
To solve the above-mentioned problems, Authorization Notice No. is that the Chinese patent of CN2508688Y discloses a kind of control of floor-cleaning machine
Structure processed, technical solution be, the center of handle is equipped with through-hole, and two guide rods are socketed on two pillars of handle rear shell, and
One end of guide rod is contacted with the boss on center control handle, and the other end is oppressed respectively at the both ends of elastic slice.Boss on elastic slice
With the engaging portion contacts of control handle.Center control handle is placed in through-hole, and both ends are embedded in handle.It can be realized list
Hand control, operation floor-cleaning machine.
But in practical applications, above-mentioned technical proposal can only realize that two hands are alternately mediated, and cannot liberate completely double
Hand, operator still need to mediate always control handle when using floor-cleaning machine, and the labor intensity of operator is still very
It is high.
Utility model content
The purpose of the utility model is to provide a kind of control switch structures for floor-cleaning machine, always without operator
Control handle is mediated, the labor intensity of operator is reduced.
The above-mentioned technical purpose of the utility model has the technical scheme that
A kind of control switch structure for floor-cleaning machine, including be mounted on the intracorporal host of floor-cleaning machine shell and connect with host
The control handle connect, the control handle are rotatably installed in handle side, and the host is equipped with elastic contact blade, the control hand
Connecting rod straight down is fixedly connected on handle, the connecting rod is hinged with hinge bar far from one end of control handle；The host
It is rotatably equipped with driving wheel on side wall, arc notch and arc bayonet are symmetrically arranged on the side wall of the driving wheel；It is described hinged
Bar is hinged on driving wheel edge, and its hinge joint is located on the line of symmetry of arc notch and arc bayonet；It is sliding on the host
Dynamic to be equipped with the abutting block along the setting of hinge bar length direction, the abutting block is supported close to one end of driving wheel with driving wheel side wall
