Description
Technical field:
The utility model belongs to agricultural machinery technological field, specifically, more particularly to a kind of hand handle with shock-damping structure
Fixed device.
Background technique:
Hand handle fixed block is the essential structure of clipping operation handle on shoulder-hanging brush saw, existing shock mitigation system because
Structure is complicated, causes hand handle fixed block to have bigger volume, while weight is also followed by increase；It is not equipped with shock mitigation system
Although hand handle fixed block possesses lesser volume, but because thus machine vibration is transmitted to arm, will lead to operator's body not
It is suitable, so that machine can not be used for a long time.
Summary of the invention:
In order to solve the disadvantage that weight is big or vibration is big existing for traditional hand handle fixed block in the prior art, the utility model
A kind of handle fixing device with shock-damping structure being different from the prior art is provided, can reduce shoulder-hanging brush saw makes
The vibration that used time generates is injured caused by human body.
To achieve the goals above, the utility model adopts the following technical solutions realization:
On a kind of handle fixing device with shock-damping structure, including hand handle upper press cover, hand handle lower cover, shock absorber part, aluminum pipe
Gland and aluminum pipe lower cover, the hand handle upper press cover are connect with hand handle lower cover, and aluminum pipe upper press cover is connect with aluminum pipe lower cover, institute
It states and is equipped with gap between hand handle lower cover and aluminum pipe upper press cover, and the hand handle lower cover and aluminum pipe upper press cover are connected by shock absorber part
It connects.
Further, the width in the gap between the hand handle lower cover and aluminum pipe upper press cover is 1~5mm.
Further, the shock absorber part is damping spring.
Further, the damping spring is equipped with four to the six roots of sensation.
Further, the steel wire diameter of the damping spring is 2.5mm.
Compared with prior art, the utility model has the beneficial effects that
1, existing fixed block is small in size without damping, and the volume with damping is excessive, and weight is big；The utility model both guaranteed
Most of vibrations can be filtered out, obtain preferable feel, but can guarantee it is small in size, it is light-weight；
2, structure is simple, highly reliable, good damping effect.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram that the utility model is installed and used.
In figure: 1, hand handle upper press cover；2, hand handle lower cover；3, damping spring；4, aluminum pipe upper press cover；5, aluminum pipe lower cover；
6, aluminum pipe；7, hand handle；8, little spring；9, big spring.
Specific embodiment:
Below by specific embodiment and in conjunction with attached drawing, the utility model is described in further detail.
Embodiment 1:
As shown in Figure 1, a kind of handle fixing device with shock-damping structure, including hand handle upper press cover 1, hand handle lower cover 2, subtract
Shake part, aluminum pipe upper press cover 4 and aluminum pipe lower cover 5, the hand handle upper press cover 1 are connect with hand handle lower cover 2, aluminum pipe upper press cover 4 and
Aluminum pipe lower cover 5 connect, between the hand handle lower cover 2 and aluminum pipe upper press cover 4 be equipped with gap, and the hand handle lower cover 2 with
Aluminum pipe upper press cover 4 is connected by shock absorber part.
Embodiment 2:
The shock absorber part is yielding rubber or damping spring 3, and yielding rubber is similar with the mounting means of damping spring 3, this
Embodiment is illustrated by taking damping spring 3 as an example.
A kind of handle fixing device with shock-damping structure, the hand handle upper press cover 1 are connected with hand handle lower cover 2 by screw
It connects, the aluminum pipe upper press cover 4 is connected by screw to aluminum pipe lower cover 5；The outer diameter of the damping spring 3 be it is up-small and down-big, subtract
Shaking spring 3 includes little spring 8 and big spring 9, and little spring 8 is structure as a whole with big spring 9, the outer diameter of the little spring 8 with greatly
The outer diameter ratio of spring 9 is 2:3~6:7." convex " word slot, big spring 9 are equipped between hand handle lower cover 2 and aluminum pipe upper press cover 4
It penetrates in slot and fixes from side, little spring 8 is fixedly connected by screw with hand handle lower cover 2.
The width in the gap between the hand handle lower cover 2 and aluminum pipe upper press cover 4 be 1~5mm (i.e. hand handle lower cover 2 with
The distance between aluminum pipe upper press cover 4 is 1~5mm)；Preferably 2~3mm, can proof strength be avoided that vibration again, comfort compared with
It is high.
The damping spring 3 is equipped with four to the six roots of sensation；Preferably four, can proof strength be avoided that vibration, installation side again
Just.
The steel wire diameter of the damping spring 3 is 2.5mm；Both the effect that can guarantee damping, but also with enough intensity.Its
His part is same as Example 1.
The working principle that the utility model is installed and used are as follows:
As shown in Fig. 2, hand handle 7 is fixed by hand handle upper press cover 1 and hand handle lower cover 2, aluminum pipe 6 passes through aluminum pipe upper press cover
4 and aluminum pipe lower cover 5 fix, aluminum pipe 6 connects engine and gear-box, and gear-box, engine, the hard axis inside aluminum pipe are shakes
Dynamic source, vibration can reach aluminum pipe lower cover 5 and aluminum pipe upper press cover 4 by aluminum pipe 6, but due to hand handle lower cover 2 and aluminum pipe
Gap is equipped between upper press cover 4, hand handle 7, there is no directly contacting, has eliminated 90% by four damping springs 3 with aluminum pipe 6
Above vibration, therefore the vibration very little that when staff holds hand handle 7 can experience, comfort are higher.
