Abstract
The utility model relates to a moving forward and backward control handle device which is mainly used for a non-driving type scrubber capable of moving forwards and backwards. A left control handle (1), a right control handle (2) and a middle connecting rod (3) are connected, and an extension rod (4) is arranged in the middle of the middle connecting rod. One end of a reset spring (5) is connected with a mounting plate (8), and the other end of the reset spring (5) is connected with the extension rod (4). An upper microswitch (6) and a lower microswitch (7) are mounted on a mounting plate and extend out of the two sides of the extension rod respectively. The moving forward and backward control handle device has the advantages that the occupied space is reduced, the machining cost is saved, the dismounting, mounting and maintaining time is shortened, and the like.
Description
Technical field
The utility model relates to a kind of non-driving-type floor-cleaning machine manipulation device, relates in particular to a kind of forward-reverse control crank device.
Background technology
Along with expanding economy, society's improving constantly the requirement of keeping a public place clean, employed labor force's cost constantly increases and the technology of keeping a public place clean constantly perfect, nowadays to floor, ceramic tile, there are various floor-cleaning machines in the area of maintenance of keeping a public place clean of the various hard grounds such as marble, its operation principle is generally in head part, to be furnished with a motor to drive brush to rotate, ground is rotated to formula clean, in brush rotation, there is clear water to flow to brush central hole, brush rotation limit side washing is brushed like this, make the spot on ground, greasy dirt, impurity cleans cleaner, then reclaim the sewage of washing ground, to guarantee the cleaning effect on ground, in order to increase work efficiency, therefore automatic hand-pushing type ground washing machine is born, and the forward-reverse control crank device indispensable important composition parts that are automatic hand-pushing type ground washing machine.But on a lot of floor-cleaning machines, the structure of forward-reverse control crank device, installation, maintenance, dismounting and operation are all not fully up to expectations.
Structure is varied on the market at present, having a kind of is button structure, need to click the key that advances, and then righting machine direct of travel, machine could be advanced by your desirable direction, and this structure exists, in button, hand need leave machine, now machine is also on-stream, easily makes machine sideslip, occurs dangerous, also have a kind of relatively simple forward-reverse control crank device to be and our the same being mounted on control box of utility model forward-reverse handle apparatus, first this device has gone out to be connected a complicated cam mechanism at intermediate connecting rod, when machine moves forward, cam mechanism rotates forward half-turn, when machine moves backward, cam mechanism rotates half-turn backward, and cam mechanism volume is large, be fixed by bolts on installing plate, secondly, installing plate need have a certain degree with intermediate connecting rod, only be adjusted to certain angle, operation is just light, this device takes up room greatly, complex structure, manufacturing cost is high, mounting or dismounting trouble, and our this utility model forward-reverse control crank device, difference due to structure and design concept, these problems have all obtained good solution.
Utility model content
The technical problem that the utility model solves is to overcome above-mentioned defect, and a kind of forward-reverse control crank device is provided, and is meeting on the basis of its function, reduces to take up room, cost-saving, while shortening loader.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of forward-reverse control crank device, be mainly used in non-driving-type, have forward on mobile backward floor-cleaning machine, comprise left control crank, right control crank, intermediate connecting rod, extension bar, back-moving spring, upper microswitch, lower microswitch, installing plate, wherein left control crank, right control crank are connected with intermediate connecting rod, the middle part of intermediate connecting rod is provided with extension bar, back-moving spring one end is connected with installing plate, one end is connected with extension bar, upper microswitch, lower microswitch are arranged on installing plate, lay respectively at the both sides of extension bar.Intermediate connecting rod and extension bar can be one, can separately be fixedly connected with.
When rotating operation handle, when the extension bar of intermediate connecting rod and upper microswitch are closed, machine moves to a direction, when counter-rotation operating grip, when the extension bar of intermediate connecting rod and lower microswitch are closed, machine moves in the opposite direction, i.e. direction of retreat of a direction of advance.
Described forward-reverse control crank device, left control crank, right control crank one side all have semi-circular recesses, make finger by the comparative comfort that gets on.
Described forward-reverse control crank,, all there is an outer larger than installation shaft at left control crank, right control crank circular hole installation shaft place, and this outer can directly contact fixing with installation control crank interface.
Described forward-reverse control crank device, left control crank, its installation shaft one side of right control crank are square, insert in intermediate connecting rod groove, in lever operated process, left control crank, right control crank can not changed with respect to intermediate connecting rod position.
Described forward-reverse control crank device, left control crank, its installation shaft one side of right control crank are square, and on a square opposite, have a runway slotted hole, for regulating forward-reverse control crank mounting distance.
The utility model beneficial effect is: meeting on the basis of its structure function, reducing to take up room, saving processing cost, shortening handling and maintenance man-hours.
