A more detailed technical solution of the present invention is as follows: A portable generator, comprising a housing, a handle provided on the housing, and a generator set fixed in the housing; the handle is fixed at the lower part to a link span in the housing; a cylinder head cover of the generator set is provided with an installation slice extending toward both ends; the installation slice is sheathed with a shock-absorbing sleeve and fixed and connected to the link span; the generator set is connected at the bottom with the housing through a shock-absorbing mat; the shock-absorbing sleeve is provided on a side with a slot, into which is one end of the installation slice inserted; the installation slice and the shock-absorbing sleeve are provided with a connecting hole; the shock-absorbing sleeve is provided on the underside with a concave pressing block, which is fixed with a nut; the link span and the installation slice are provided through them with a bolt, which together with the nut fixes and connects the installation slice to the link span in a screwing manner; the pressing block is provided on the upper surface with a bulge, corresponding to which on the bottom surface is the shock-absorbing sleeve provided with a groove; the generator set is provided at the bottom with a base plate; the shock-absorbing mat is provided with an upper bolt extending upward to be connected with the base plate and provided with a lower bolt extending downward to be connected with the housing; the housing is provided at the bottom with shock-absorbing feet, which are provided with female thread; and the lower bolt is fixed and connected to the shock-absorbing feet through the bottom of the housing.
The present invention has the following advantages:
1. The present invention fixes the generator set to the link span and the casing through the shock-absorbing sleeve, the shock-absorbing mat and the shock-absorbing feet, which is better in shock-absorption effect and can prolong service life of the generator.
2. The present invention is simpler in structure, and more convenient for handling and maintenance.
3. The generator set of the present invention is fixed inside the housing through the link span and the base plate, which is advantageous to heat dissipation of the generator set and reduces the overall weight.
The present invention will be further described below according to drawings and embodiments.
