Abstract
The invention discloses the wire spool device of a kind of electric garden tool, the particularly pedal wire spool device of a kind of electric garden tool, rotate the drive mechanism adopted including wire spool support, wire spool, pedal and pedal-driven wire spool, user pushes down on the pedal and drives wire spool to rotate coiling by drive mechanism.Which solving people keeps stance to use wire spool device to complete the technical problem of take-up, and in prior art of comparing, user generally requires and keeps half crouch or posture a period of time of bending over can complete whole take-up process, and it is more laborsaving, easily.
Description
Technical field
The present invention relates to the wire spool device of a kind of electric garden tool, particularly the pedal wire spool device of a kind of electric garden tool.
Background technology
Along with being on the increase of greenbelt in city, the continuous expansion of greenbelt area, the requirement of the electric garden tool of finishing greenbelt is also increasingly higher.The particularly wire spool device of electric garden tool, owing to greenbelt area is excessive, it requires that wire spool device can the longer power line of folding and unfolding.
The structure of existing above-mentioned wire spool device is relatively simple, generally comprises wire spool support arm, wire spool and handle-driving mechanism, and wherein wire spool has been hinged on wire spool support arm, and handle-driving mechanism and wire spool are in transmission connection.The wire spool of said structure is in specifically used, user by hand fixed handle driving mechanism thus driving wire spool to complete take-up, consider the whole height of wire spool support arm, people generally requires maintenance half crouch or posture a period of time of bending over can complete whole take-up process, therefore easily allowing user produce tired out, take-up is inefficient.
Summary of the invention
The pedal wire spool device that the invention aims to solve above-mentioned the deficiencies in the prior art and provide a kind of electric garden tool.Have employed above-mentioned pedal wire spool device, user may stand in whole take-up process.
nullTo achieve these goals，The pedal wire spool device of a kind of electric garden tool designed by the present invention，Including wire spool support and wire spool，Wire spool is actively socketed in the rotating shaft of wire spool support，It is provided with case in the side of wire spool，The center of this case is formed with axle sleeve，And on the external port edge of axle sleeve, it is provided with spacing back-off，Rotating shaft runs through above-mentioned axle sleeve，On described axle sleeve, movable sleeve is connected to the toothed disc being positioned at case successively、Wind spring、Position-arresting disk and drive plate，Drive plate therein is provided with the first accommodation chamber and is distributed in the switch pad of this first accommodation border, chamber，This switch pad runs through and draws this case，Switch pad is socketed with reset ring spring，Its strength force coefficient is less than the strength force coefficient of above-mentioned wind spring，The described first bottom surface periphery uniform ring holding chamber has a groove，Position-arresting disk and wind spring are respectively positioned on this first accommodation intracavity，Drive plate entirety slidably reciprocates between position-arresting disk and spacing back-off，And mutually link with wire spool in rotating shaft direction of rotation，The inner termination of wind spring is fixed on the center of position-arresting disk，Described toothed disc is grouped into by gear parts and disk body section，Disk body part therein is fastened on above-mentioned first and holds intracavity，Its bottom surface periphery is provided with the boss being engaged mutually with above-mentioned groove，The external end head of wind spring is connected with disk body part，Gear parts is engaged with tooth bar，This tooth bar is provided with joint pin，Described case is additionally provided with gathering sill，Above-mentioned joint pin runs through gathering sill and connects upper footboard，Above-mentioned rotating shaft is also socketed with driving lever，Driving lever arranges high bottom surface coordinate with above-mentioned switch pad；When the eminence of bottom surface high on driving lever is crimped on switch pad, the groove on above-mentioned middle drive plate is separated with the boss on toothed disc.
The pedal wire spool device of above-mentioned a kind of electric garden tool, when the eminence of bottom surface high on shifting block is not crimped on switch pad, namely driving lever is in take-up position, the now boss occlusion corresponding with the groove on drive plate in the disk body part of toothed disc, then step on pedal, when pedal down moves can the motion of band carry-over bar, tooth bar again can driven gear disc spins, toothed disc drives wire spool to rotate by drive plate, thus playing the effect of take-up；Having a wind spring on toothed disc, when toothed disc rotates, wind spring can be tightened up accumulation of energy.When pedal is floored, then somewhat unclamping foot, be tightened up now wind spring due to wind spring and will flick thus driven gear dish opposite direction rotates, toothed disc is replied by rack drives pedal.In the process that above-mentioned pedal is replied, owing to toothed disc and drive plate are by spring compression, owing to the strength force coefficient of wind spring is less than the strength force coefficient of above-mentioned wind spring, so toothed disc will depart from drive plate, toothed disc just can rotate and drive pedal to reply, drive plate is motionless simultaneously, thus can reach pedal and move back and forth.
When the eminence of bottom surface high on shifting block is crimped on switch pad, namely driving lever is in unwrapping wire position, driving lever withstands switch pad inward, switch pad withstands drive plate, so that drive plate separates with toothed disc, now rotating wire spool again, toothed disc would not move therewith, it is achieved thereby that the function of unwrapping wire.
As further preferably, above-mentioned drive plate is made up of the pressing plate of center disk body and be evenly distributed on disk body border, center more than two pieces, and every block pressur plate Jun Yu center disk body is mutually twisted, center therein disk body is provided with the first accommodation chamber, has all been at least connected with a switch pad on every block pressur plate.In this preferred version, installation relation between drive plate and miscellaneous part is reasonable, and the production materials of drive plate are relatively economized simultaneously, and it is strong for economic rationality.
As further technological improvement, the slot cross-section of the above-mentioned first groove holding the bottom surface periphery annular arrangement in chamber is wedge shaped, and groove from shallow to deep consistent towards the take-up anglec of rotation with wire spool.When driving lever is in take-up position, when user steps on pedal, the transmission stability between toothed disc and the drive plate in said structure is high, it is not easy to slip phenomenon occur；Being in the process of reply at pedal, the frictional resistance of toothed disc convex platform is reduced by said structure further groove, under the reset force effect of wind spring simultaneously so that toothed disc and drive plate are easier to overcome the elastic force of reset ring spring to realize relatively rotating between the two.
So that driving lever possesses object of reference when being adjusted, and promote the adjustment stability of driving lever, above-mentioned driving lever is positioned at the outside of case, the outer surface of described case is additionally provided with gib block and stop bit block, described driving lever is provided with the guiding groove being interlocked with above-mentioned gib block, and when this driving lever and gib block mutually keep off and connecing, the eminence of its high bottom surface is crimped on switch pad.
For the pedal allowing user more smoothly trample in this wire spool device, promote its job stability, above-mentioned wire spool support is further fixed on retractable support pedal.
Have employed the pedal wire spool device of a kind of electric garden tool that the present invention obtains, user can stand whole take-up process, in prior art of comparing, user generally requires and keeps half crouch or posture a period of time of bending over can complete whole take-up process, it is more laborsaving, easily.
