Description
Technical field
This utility model, by the novel adjusting means relating to chain saw, particularly relates to the saw chain adjusting means of chain saw.
Background technology
Current chain saw mainly has two kinds, and a kind of is the gasoline chain saw with electromotor as power, and another kind is the electric chain saw with motor as power, and these two kinds of chain saws are all that the saw chain by high-speed motion realizes cutting function.If in use saw chain is crossed pine and may be jumped out of guide plate, cause the injury to operator, and the saw chain of tension may cause high temperature fault due to the excessive friction between saw chain and guide plate, causes damage chain saw.Therefore chain saw is before use it is generally required to be adjusted saw chain, and existing chain saw is typically all tensioning degree and the compression degree being regulated saw chain by hold down gag and front-and-back adjusting device respectively during regulation, waste time and energy during causing regulation, and tensioning degree and the compression degree of saw chain are all not quite similar when regulating every time, cannot unify, it is difficult to ensure the safety during chain saw use.Therefore some producers start to research and develop and reach tensioning simultaneously and compress the structure of purpose by once rotating regulation, but current this structure be mostly required for being coordinated by numerous parts realize, relatively costly, it is impossible to carry out marketing.
Summary of the invention
This utility model is for the adjusting part spare and accessory parts of saw chain are more, relatively costly present in prior art, cannot be carried out the defects such as marketing, it is provided that the saw chain adjusting means of a kind of new chain saw.
In order to solve above-mentioned technical problem, this utility model is achieved through the following technical solutions:
The saw chain adjusting means of chain saw, including chain saw housing, knob assembly, saw chain guide plate assembly, adjusting part, it is provided with screw on described chain saw housing, described adjusting part includes pushing component, unilateral bearing, torsion spring, described unilateral bearing one end is connected with knob assembly, the unilateral bearing other end is locked on the top of torsion spring, the bottom of described torsion spring is connected with pushing component, described pushing component is connected with saw chain guide plate assembly, described screw passes saw chain guide plate assembly, adjusting part is also threadeded with knob assembly, described knob assembly is moved up and down by screw and passes through unilateral bearing, torsion spring, pushing component promotes saw chain guide plate assembly to move forward and backward.
nullScrew on chain saw housing is for unified location saw chain guide plate component、Adjusting part、Knob assembly，Wherein screw is threadeded with knob assembly，Knob assembly can be moved up and down by screw in rotary course forward or backwards，Thus compress or loosen adjusting part、Saw chain guide plate assembly，During knob assembly rotates forward，Unilateral bearing inner ring and outer ring are because of locked at forward，Unilateral bearing entirety is caused to rotate forward also with knob assembly，Thus drive torsion spring to rotate forward，Torsion spring promotes saw chain guide plate assembly to move forward by pushing component while rotating，So that saw chain gradually tensioning，When knob assembly moves down and puts in place，Saw chain guide plate assembly is also pushed forward and puts in place，I.e. compress the tensioning regulation also synchronizing to achieve saw chain while having operated，Wherein torsion spring can not only play the effect of middle connection，And there is certain elasticity，When compression puts follow-up continuous rotation in place, torsion spring will produce certain elastic deformation，Thus feed back to user，Promote Consumer's Experience.And when knob assembly rotates backward, reversely can be freely rotatable between unilateral bearing inner ring and outer ring, so that unilateral bearing entirety will not rotate along with the rotation of knob assembly, torsion spring i.e. will not be driven to rotate from without promoting saw chain guide plate assembly to move by pushing component, ensure that the tensioning degree of chain saw will not change while knob assembly screws out, safer.This utility model is by unilateral bearing, both torsion springs and coordinating between knob assembly, pushing component, promotion saw chain guide plate assembly, achieve the adjusted in concert compressed with tensioning dexterously, the most simple to operate, and parts are few, greatly reduce production cost, be more beneficial for the popularization operation in market.
As preferably, the saw chain adjusting means of chain saw described above, described pushing component includes push pedal, drive, regulation mold insert, it is provided with flat thread bottom described drive, described push pedal top is equipped with boss, being connected with drive bottom described regulation mold insert, regulation mold insert top is locked on the bottom of torsion spring, and described push pedal is connected with saw chain guide plate assembly.
During regulation, drive can be driven to rotate by regulation mold insert during torsion spring rotates, the then also concomitant rotation of the flat thread bottom drive the boss at push pedal top is produced outside pressure, thus promote push pedal to move forward and drive saw chain guide plate assembly to move forward, thus realize the tensioning to saw chain and regulate.
As preferably, the saw chain adjusting means of chain saw described above, described pushing component also includes positioning sleeve, pad, La Quan, it is additionally provided with positioning table bottom described drive, it is provided with elongated hole in described push pedal, described positioning table stretches in the elongated hole of push pedal, described positioning sleeve, pad, draws snare on positioning table and inconsistent with the inner side of elongated hole.Positioning sleeve, pad, La Quan enable to be accurately positioned between drive and push pedal so that more accurate during regulation.
As preferably, the saw chain adjusting means of chain saw described above, it is additionally provided with clamping bench bottom described regulation mold insert, described drive is also equipped with fastener hole, described clamping bench stretches in fastener hole.Making to regulate mold insert can drive drive to rotate when rotating accurately, it is to avoid swiping phenomenon occur, safer during use.
