Utility model content
The utility model provides a kind of stability in use better and use more conveniently drum muffler for above problem.
The utility model overcomes the above problems technical scheme used: provide a kind of drum muffler with following structure, it comprises fixed mount, adjuster bar, silencing pad and support, described adjuster bar is rotatably connected on fixed mount, described silencing pad is fixedly connected with support, described support is provided with screw, screw mandrel is combined with in described screw, described screw mandrel is connected with adjuster bar by gear train, and gear train is fixed on fixed mount, described support is provided with pilot hole, described gear train is provided with the guide pole coordinated with pilot hole, and guide pole and screw mandrel be arranged in parallel.
After adopting above structure, compared with prior art, the spacing of the utility model owing to adopting screw mandrel screw mechanism to regulate silencing pad and drum surface, then because of the characteristic of screw mandrel and screw, do not have originally too much pin joint, make the impact that silencing pad is not easily vibrated, the stability of position is better, in use do not need frequent adjustment, use easier; The precision simultaneously regulated is also relatively high, is convenient to the use of user.Therefore the utility model has stability in use better and use more conveniently feature.
As improvement, described gear train comprises holder and end cap, and holder is fixedly connected with end cap, and described holder and end cap are formed in cavity and be provided with gear-driven assembly, the input end of described gear-driven assembly is connected with adjuster bar, and the output terminal of gear-driven assembly is connected with screw mandrel; Then the stability of gear-driven assembly transmission is better, and precision is also higher, also relatively laborsaving during adjustment, and then degree of regulation of the present utility model and stability in use are improved further.
As further improvement, described gear-driven assembly comprises the first umbrella shape tooth and the second umbrella shape tooth, the first described umbrella shape tooth and the second umbrella shape tooth are all rotatably connected in holder, the first described umbrella shape tooth engages with the second umbrella shape tooth, and the axis of the first umbrella shape tooth is mutually vertical with the axis of the second umbrella shape tooth, the first described umbrella shape tooth is connected with screw mandrel, and the second described umbrella shape tooth is connected with adjuster bar; The then drive mechanism of this umbrella shape tooth, parts are less, are convenient to installation and maintenance, advantage of lower cost, and stability when simultaneously running is also better.
As improving further, the first described umbrella shape tooth is provided with columniform projection away from one end of screw mandrel again, the axis of described projection and the dead in line of the first umbrella shape tooth, and the described bearing that projects through is connected with holder inwall; After then arranging like this, bearing significantly can reduce resistance suffered when the first umbrella shape tooth rotates, and dirigibility when the first umbrella shape tooth is rotated is better, the use of the user that is more convenient for.
As further improving, described gear-driven assembly comprises worm gear and worm screw, and worm gear and worm screw are all rotatably connected in holder, and described worm gear is connected with screw mandrel, and described worm screw is connected with adjuster bar; Then the parts of worm gear structure are less, are convenient to installation and maintenance, advantage of lower cost, and stability when simultaneously running is also better.。
