The structure of tradition topside cylinder mainly comprises motor, swing span, cylinder.Adopt coupler to be connected between swing span and the cylinder, require the non-gun iron link that is connected between them, permission can have slight swing in the junction, therefore present employed coupler generally adopts gimbal coupling.But the gimbal coupling manufacturing cost is higher, is unfavorable for the production in enormous quantities of product, in addition also very inconvenience of assembling.

Summary of the invention

For the deficiencies in the prior art, the utility model provides a kind of topside cylinder, and the cheap and processing of this topside cylinder and assembling be very convenience all.

The utility model is achieved by following technical proposals: the topside cylinder, comprise swing span and cylinder, be equipped with the drum drive axle in the described swing span, be connected with connecting bushing on the described drum drive axle, described connecting bushing one end is equipped with adapter shaft, be provided with some projections on the sidewall of described adapter shaft, described connecting bushing is provided with the first groove that matches with described projection corresponding to these described high spots, and described adapter shaft is fixed on the described cylinder.

In the technique scheme, described projection is along having arcwall face on the adapter shaft axial direction.

In the technique scheme, offer the second groove at described adapter shaft, offer the first tapped bore that is communicated with the second groove at the adapter shaft sidewall, be provided with installation shaft on the cylinder, described installation shaft is sheathed in the second groove, twist in described the first tapped bore and be provided with the first bolt, described the first bolt leans installation shaft.

In the technique scheme, be provided with dust protecting cap in the junction of described swing span and cylinder.

In the technique scheme, be provided with on the described connecting bushing in three-flute corresponding to drum drive axle, described drum drive axle sleeve is located in the described three-flute.

In the technique scheme, be provided with fourth hole at described connecting bushing, described fourth hole is communicated with the first through hole and three-flute, the drum drive axle is provided with the second tapped bore corresponding to the fourth hole position, also comprise the second bolt, described the second bolt is twisted by fourth hole and is located in the second tapped bore.

The utility model compared with prior art has following beneficial effect: solved the drawback that adopts the gimbal coupling high cost between swing span and the cylinder, saved greatly manufacturing cost, and assembling is also more convenient.
