Abstract
The utility model provides a sonic tube connecting mechanism. The sonic tube connecting mechanism comprises an inner gear ring and an outer gear ring, wherein the inner gear ring is arranged at one end of an upper sonic tube or a lower sonic tube, the outer gear ring is arranged at one end of the lower sonic tube or the upper sonic tube, and the upper sonic tube and the lower sonic tube are connected through the combination of the inner gear ring and the outer gear ring; gear teeth are processed in part of the outer diameter periphery of the inner gear ring, and the gear teeth are meshed with an outer gear mechanism. The inner gear ring is combined with the outer gear ring through the utilization of the meshing transmission of part of the gear teeth, on the outer diameter of the inner gear ring, with the outer gear mechanism, thereby realizing the rapid combination and separation of the sonic tube mechanism. The sonic tube connecting mechanism has the characteristics of simplicity in operation, rapidness and convenience in connection and convenience in the repair and the exchange of parts.
Description
Technical field
The utility model relates to sound pipe and connects field, and what relate to specifically is a kind of easy sound pipe coupling mechanism.
Background technique
Existing upper and lower sound pipe joining method is all to adopt scyewed joint, its subject matter is to make in the connection place of upper and lower sound pipe two flange plate that diameter is larger, and then with the bolt being distributed on flange plate, upper lower flange is linked together, could realize the connection of sound pipe.Because the operation of scyewed joint is all manually to carry out, install and remove very time-consuming, efficiency is low, labor intensity is large, bring adverse effect not only to the sealing effect of sound pipe, also give maintenance and change parts and bring very big inconvenience, and causing damage likely in operating process upper and lower sound pipe body, being unfavorable for very much applying.
Chinese patent CN201120305736.1 discloses a kind of muffler pipe connection structure, the locking of one end of its hush tube and metal tube, and the other end is locked with anti-shake apparatus, in the outer cover of metal tube and hush tube, has sebific duct and metallic sheath.This complex structure, waste material, manufacturing procedure are many, increase cost of production, and easily occur hush tube obscission.
Summary of the invention
In order to overcome the deficiency of above-mentioned existing sound pipe connecting mode, the utility model provides a kind of easy sound pipe coupling mechanism, and it is simple and compact for structure, easy to operate, can realize automation mechanized operation.
In order to reach foregoing invention object, the utility model provides following technical solution:
A sound pipe coupling mechanism, comprises ring gear and external toothing.Ring gear is arranged on one end of sound pipe or lower sound pipe, and external toothing is arranged on one end of lower sound pipe or upper sound pipe, and the connection between upper sound pipe and lower sound pipe realizes by the combination of ring gear and external toothing; In described ring gear external diameter circumference subrange (30 degree), process the gear teeth, the gear teeth are meshed with outer gear mechanism.
Described ring gear and external toothing are direct and sound pipe is integrally welded.The internal tooth of ring gear has identical modulus and the number of teeth with the external tooth of external toothing.
Further, the internal tooth spacewidth of ring gear is greater than the external tooth transverse tooth thickness of external toothing.
The beneficial effects of the utility model are: the gear teeth on (1) external toothing can pass the teeth groove of ring gear, quick combination and the disengaging of sound pipe and lower sound pipe in realization easily; The local gear teeth on ring gear external diameter are externally realized quick rotation under the drive of gear mechanism, the angular range rotating can be completed by automatic detection and control system as required, the docking time of greatly having saved upper and lower sound pipe mechanism, has alleviated labor strength, has improved working efficiency.(2) sound pipe connects closelyr, and the reliability connecting is strengthened, and reduces the sound pipe probability that comes off.(3) compare with other existing linkage structures, can complete in the short period of time the processing that sound pipe connects, realized with low cost, have simple to operate, rapid and convenient, maintenance and change component feature easily.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of sound pipe coupling mechanism of the utility model.As shown in drawings, 1 is upper sound pipe, and 2 is ring gear, and 3 is external toothing, and 4 is lower sound pipe.
Fig. 2 is that gear ring is in conjunction with figure.
Embodiment
In Fig. 1, the external diameter of the internal diameter of ring gear 2 and upper sound pipe 1 one end is welded as a whole, the external diameter of the internal diameter of external toothing 3 and lower sound pipe 4 one end is welded as a whole; According to modulus and the completely equal principle of the number of teeth, process the internal tooth of ring gear 2 and the external tooth of external toothing 3; After processing, the internal tooth spacewidth of ring gear 2 is greater than the external tooth transverse tooth thickness of external toothing 3, and object is in order to make the gear teeth on external toothing 3 can pass easily the teeth groove on ring gear 2, quick combination and the disengaging of sound pipe and lower sound pipe in realization.In the scope at ring gear 2 external diameter circumference 30 degree angles, process the gear teeth, to realize engagement driving with outer gear mechanism (not shown in FIG.).
As Fig. 2, when connecting sound pipe, gear teeth meshing in outer gear mechanism (not shown in FIG.) and ring gear 2 external diameter circumference subranges, externally under the drive of gear mechanism, ring gear 2 is by the angular turn of setting in advance, the gear teeth of external toothing 3 are just in time pressed in the groove above ring gear 2 gear teeth, realize the combination of ring gear 2 and external toothing 3, thereby realize the quick connection of upper sound pipe 1 and lower sound pipe 4.
Claims (5)
