Description
Technical field
The utility model relates to a kind of wire spool device of electric garden tool, particularly a kind of pedal type wire spool device of electric garden tool.
Background technology
Along with being on the increase of green belt in city, the continuous expansion of green belt area, also more and more higher to the requirement of the electric garden tool of finishing green belt.The particularly wire spool device of electric garden tool, because green belt area is excessive, so require that wire spool device can the longer power lead of folding and unfolding.
The structure of existing above-mentioned wire spool device is comparatively simple, and roughly comprise wire spool outer support, wire spool and handle-driving mechanism, wherein wire spool has been hinged on wire spool outer support, and handle-driving mechanism and wire spool are in transmission connection.The wire spool of said structure is in concrete use, user is by hand fixed handle driver train thus drive wire spool completes take-up, consider the whole height of wire spool outer support, people often needs to keep half crouch or posture a period of time of bending over can complete whole take-up process, therefore easily allow user produce tired out, take-up efficiency is not high.
Utility model content
The purpose of this utility model is the pedal type wire spool device providing a kind of electric garden tool in order to solve above-mentioned the deficiencies in the prior art.Have employed above-mentioned pedal type wire spool device, user may stand in whole take-up process.
To achieve these goals, the pedal type wire spool device of a kind of electric garden tool designed by the utility model, comprise wire spool support and wire spool, wire spool is actively socketed in the rotating shaft of wire spool support, case is provided with 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, be 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 is wherein provided with the first container cavity and is distributed in the switch pad of this first container cavity border, 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 bottom surface periphery uniform ring of described first container cavity has a groove, position-arresting disk and wind spring are all positioned at this first container cavity, drive plate entirety slidably reciprocates between position-arresting disk and spacing back-off, and mutually link with wire spool on rotating shaft hand 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 is wherein fastened in the first above-mentioned container cavity, its bottom surface periphery is provided with the boss be engaged mutually with above-mentioned groove, the external end head of wind spring divides with disk body section and is connected, gear parts is engaged with tooth bar, this tooth bar is provided with joint pin, described case is also provided with guide groove, above-mentioned joint pin runs through guide groove and connects upper footboard, above-mentioned rotating shaft is also socketed with driving lever, driving lever is arranged high bottom surface to 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 drive plate and the boss on toothed disc are separated.
The pedal type 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, boss occlusion corresponding with the groove on drive plate in the disk body part of now toothed disc, then step on stretcher, carry-over bar can be with when stretcher down moves to move, tooth bar again can driven gear disc spins, toothed disc drives wire spool to rotate by drive plate, thus plays the effect of take-up; Toothed disc has a wind spring, and when toothed disc rotates, wind spring can be tightened up accumulation of energy.When stretcher is floored, then unclamp pin a little, will flick thus the opposite spin of driven gear dish because wind spring has been tightened up now wind spring, toothed disc is replied by rack drives stretcher.In the process that above-mentioned pedal is replied, because toothed disc and drive plate are by spring application, strength force coefficient due to 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 to drive stretcher to reply, drive plate is motionless simultaneously, so just can reach stretcher crank motion.
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, thus drive plate is separated with toothed disc, now rotate wire spool again, toothed disc would not therewith move, thus achieves the function of unwrapping wire.
As further preferred, above-mentioned drive plate is made up of center disk body and the pressing plate of more than two pieces that is evenly distributed on disk body border, center, and every block pressur plate Jun Yu center disk body is engaged mutually, center disk body is wherein provided with the first container cavity, and every block pressur plate is all at least connected with a switch pad.Installation relation in this preferred version between drive plate and miscellaneous part is reasonable, and the production materials of drive plate are comparatively economized simultaneously, and it is strong for economic rationality.
As further technological improvement, the slot cross-section of the groove of the bottom surface periphery annular arrangement of above-mentioned first container cavity is wedge shape, and groove from shallow to deep towards consistent with the take-up anglec of rotation of wire spool.When driving lever is in take-up position, when user steps on stretcher, the toothed disc in said structure and the transmission stability between drive plate high, be not easy to occur slip phenomenon; Be in the process of reply at pedal, said structure further groove reduces the friction drag of toothed disc convex platform, under the reset force effect of wind spring, makes toothed disc and drive plate more easily overcome the elastic force of reset ring spring between the two and realize relatively rotating simultaneously.
Object of reference is possessed when regulating in order to make driving lever, and promote the modification stability of driving lever, above-mentioned driving lever is positioned at the outside of case, the outside face of described case is also provided with gib block and stop bit block, described driving lever is provided with the guiding groove be interlocked with above-mentioned gib block, and when this driving lever and gib block mutually keep off connect time, the eminence of its high bottom surface is crimped on switch pad.
In order to allow user can trample pedal in this wire spool device more reposefully, promoting its working stability, above-mentioned wire spool support is also fixed with retractable sustain pedal.
Have employed the pedal type wire spool device of a kind of electric garden tool that the utility model obtains, user can stand whole take-up process, in prior art of comparing, user often needs to keep half crouch or posture a period of time of bending over can complete whole take-up process, it is more laborsaving, easily.
