Abstract
The utility model discloses a chain saw which comprises a power device, a support and a shock absorption block. A supporting arm is arranged on the support, the power device is arranged on the supporting arm, one end of the power device and the support are fixed through flexible connection, the other end of the power device and the supporting arm are fixed through flexible connection, the shock absorption block is arranged between the power device and a gap of the supporting arm, and the shock absorption block is used for buffering collisions between the power device and the supporting arm. According to the chain saw, the collisions between the power device and the supporting arm can be avoided, vibrations are effectively reduced, the comfort level is improved, and labor intensity is reduced.
Description
Technical field
The utility model relates to the chain saw field, specifically relates to a kind of chain saw of damping.
Background technology
Chain saw is the abbreviation of " gasoline chain saw " or " petrol power saw ".Power saw in order to lumbering and producing material.Because it is easy to carry, operates the simple and easy outdoor study that is widely used in.
Chain saw is by gasoline engine driven, because the motion of gasoline engine casing inside crank all can make gasoline engine produce vibration, the particularly gasoline engine of single cylinder, because the change of center of gravity during motion, vibration is big than multi-cylinder usually.In order to reduce this vibrations for the influence of artificial handle, general gasoline engine and corresponding power set and handle directly can adopt and flexibly connect.This structure can effectively reduce the vibrations of handle, but flexible assembly must have certain relative displacement, and when the power set of chain saw and fuel tank relative displacement, handle also can produce rigid collision with power set.
The utility model content
(1) technical problem that will solve
At the deficiency that prior art exists, the utility model provides a kind of chain saw that can reduce vibrations.
(2) technical scheme
For achieving the above object, the utility model provides a kind of chain saw, it is characterized in that, comprise power set, support and snubber block, described support is provided with support arm, handle and fuel tank, described power set place on the described support arm, one end and the described support of described power set are fixing by flexibly connecting, the other end of described engine and described support arm are fixing by flexibly connecting, be provided with snubber block between described power set and the described support arm slit, be used for the collision of buffering power set and described support arm.
Further, described support arm is provided with plural installing hole, and described snubber block is provided with the erection column of respective numbers, and described erection column is installed in the described installing hole, and described erection column is provided with bulge loop, and described bulge loop and described installing hole are interference fit.
Further, described snubber block is acrylonitrile-butadiene rubber.
Further, described snubber block is provided with several circular holes.
(3) beneficial effect
The utility model chain saw can prevent the collision of power set and support, effectively reduces vibrations, improves comfort level, reduces labour intensity.
Description of drawings
Fig. 1 is the part-structure schematic diagram of the utility model chain saw;
Fig. 2 is the structural representation of the snubber block of the utility model chain saw;
Fig. 3 is the partial structurtes schematic diagram after the utility model chain saw support, power set and the snubber block assembling.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
The part-structure of a kind of chain saw of the present utility model as depicted in figs. 1 and 2, described chain saw comprises power set 1, support 3 and snubber block 2, described support 3 is provided with support arm 4, described power set 1 place on the described support arm 4, one end and the described support 3 of described power set 1 are fixing by flexibly connecting, the other end of described power set 1 and described support arm 4 are fixing by flexibly connecting, be provided with snubber block 2 between described power set 1 and described support arm 4 slits, be used for the collision of buffering power set 1 and described support arm 4.
In above structure, support arm 4 is conducive to the installation of power set 1, fixing, location, can make to have a plurality of contact between power set 1 and support 3 and the support arm 4, thereby guarantee the firm installation of power set 1, this structure be widely used with chain saw in the middle of.But when reality is used, because gasoline engine drives the vibrations of power set 1, can cause the collision of power set 1 and support arm 4, snubber block 2 is installed between support arm 4 and power set 1 in order to cushion this collision.Grabbing the handle of taking in fuel tank in the chain saw and the work in addition also is installed on the support 3.
Described support arm 4 is provided with plural installing hole 41 in addition, and described snubber block 2 is provided with the erection column 21 of respective numbers, in the present embodiment, is preferably two installing holes 41.Described erection column 21 is installed in the described installing hole 41, and described erection column 21 is provided with bulge loop 22, and described bulge loop 22 is interference fit with described installing hole 41.
Fig. 3 is the partial structurtes schematic diagram after the utility model chain saw support, power set and the snubber block assembling.One end and the described support arm 4 of described power set 1 are fixing by flexibly connecting, wherein said snubber block 2 is installed on the described support arm 4, this snubber block 2 is not used in support arm 4 and is connected with power set 1, snubber block 2 does not contact with power set 1 in the ordinary course of things, and just prevents the direct collision of power set 1 and support arm 4 when in use.Flexibly connect with other and to compare, this snubber block is 2 easy for installation, cost is low, conveniently uses repair demolition.
The beneficial effects of the utility model: prevent the collision of power set and support, effectively reduce vibrations, improve comfort level, reduce labour intensity.Use the yielding rubber piece can be with the damping of foregrip by original according to experiment showed,
Be reduced to
The damping of back handle is by original
Be reduced to
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
