Description

Shock absorption structure of small engine

Technical Field

The utility model relates to a small-size engine technical field, concretely relates to small-size engine shock-absorbing structure.

Background

The small engine has the characteristics of large power per liter, small volume, simple structure, low cost and the like, and is widely used in portable tools. The engine can produce continuous rocking in the motion process, need install the shock attenuation foot and carry out the shock attenuation, protect the engine. The shock absorption foot is installed through the bolt mostly, and at the in-process of twisting bolt installation shock absorption foot, the shock absorption foot can rotate along with the rotation of bolt, leads to shock absorption foot offset, can't be in best operating position for the shock attenuation effect descends.

Disclosure of Invention

An object of the utility model is to overcome prior art not enough, provide a small-size engine shock-absorbing structure.

In order to achieve the above object, the present invention provides the following technical solutions:

the utility model provides a small-size engine shock-absorbing structure, including installing the shock attenuation foot between engine housing and base, the shock attenuation foot is including consecutive last shock attenuation shell fragment, rubber pad and lower shock attenuation shell fragment, it is connected with engine housing to go up the shock attenuation shell fragment, lower shock attenuation shell fragment is connected with the base, engine housing is equipped with top barrier strip and first side barrier strip with the junction of last shock attenuation shell fragment, top barrier strip and first side barrier strip are connected and perpendicular mutually, the position that the top barrier strip was corresponding with the top of last shock attenuation shell fragment, the position that first side barrier strip was corresponding with a side of last shock attenuation shell fragment.

Preferably, one end of the top end blocking strip, which is far away from the first side edge blocking strip, is connected with a second side edge blocking strip, and the position of the second side edge blocking strip corresponds to the other side edge of the upper shock absorption elastic sheet.

Preferably, the outer side of the joint of the top barrier strip and the first side barrier strip is provided with a limiting piece.

Preferably, the connection part of the lower damping elastic sheet and the base is provided with a limiting frame.

Compared with the prior art, the beneficial effects of the utility model are that: the structure for blocking the rotation of the upper damping elastic sheet is formed by the top blocking strip and the first side blocking strip, so that the situation that the upper damping elastic sheet is knocked to influence the final fixed position of the upper damping elastic sheet in the installation process is avoided, the shock absorption effect is prevented from being deteriorated due to the fact that the upper damping elastic sheet is not installed in place, and the service life of the upper damping elastic sheet is prolonged.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1-6, a small-size engine shock-absorbing structure, including installing shock attenuation foot 1 between engine housing 3 and base 2, shock attenuation foot 1 is including consecutive last shock attenuation shell fragment 4, rubber pad 5 and lower shock attenuation shell fragment 6, it is connected with engine housing 3 and base 2 through the bolt respectively to go up shock attenuation shell fragment 4 and lower shock attenuation shell fragment 6, the junction of engine housing 3 and last shock attenuation shell fragment 4 is equipped with top barrier strip 8 and first side barrier strip 9, top barrier strip 8 and first side barrier strip 9 are connected and mutually perpendicular, the position of top barrier strip 8 is corresponding with the top of last shock attenuation shell fragment 4, the position of first side barrier strip 9 is corresponding with a side of last shock attenuation shell fragment 4.

One end of the top side blocking strip 8, which is far away from the first side blocking strip 9, is connected with a second side blocking strip 10, and the position of the second side blocking strip 10 corresponds to the other side of the upper shock absorption elastic sheet 4. The top end stop strip 8, the first side stop strip 9 and the second side stop strip 10 form a door-shaped frame, so that the position of the upper damping elastic piece 4 can be better limited.

The outer side of the joint of the top barrier rib 8 and the first side barrier rib 9 is provided with a limiting piece 11. The limiting piece 11 can prevent the upper shock absorbing elastic piece 4 from being separated outwards, and further fix the position of the upper shock absorbing elastic piece 4.

The connection part of the lower damping elastic sheet 6 and the base 2 is provided with a limit frame 12. The limiting frame 12 is 7-shaped, and the limiting frame 12 is used for limiting the position of the lower damping elastic sheet 6 connected with the base 2.

The lower damping elastic sheet 6 is connected with a positioning hook 7, and the base 2 is provided with a positioning hole corresponding to the positioning hook 7.

The shock absorption elastic piece fixing device has the advantages that the structure for blocking the rotation of the upper shock absorption elastic piece 4 is formed by the top end blocking strip 8 and the first side edge blocking strip 9, the situation that the final fixed position of the upper shock absorption elastic piece 4 is affected due to the fact that the upper shock absorption elastic piece 4 rotates in the installation process is avoided, the situation that the shock absorption effect is poor due to the fact that the upper shock absorption elastic piece 4 is not installed in place is avoided, and the service life of the upper shock absorption elastic piece 4 is prolonged.

When the damping pin 1 is installed, relative displacement cannot be generated between the upper damping elastic sheet 4 and the lower damping elastic sheet 6, the rubber pad 5 cannot be torn, and the service life of the rubber pad 5 is prolonged.

The mounting positions of the upper damping elastic sheet 4 and the lower damping elastic sheet 6 are limited, so that the mounting consistency of each damping foot 1 is good.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
