Abstract
A novel rapid sealing mechanism for acoustic tubes comprises an upper acoustic tube, a lower acoustic tube, an upper spline, a lower spline and an O type seal ring, wherein the upper spline and the lower spline are directly connected with the upper acoustic tube and the lower acoustic tube, respectively; and the O type seal ring is arranged in a groove inside the joint of the upper and the lower acoustic tubes. The novel rapid sealing mechanism is characterized by the further inclusion of an inner spline gear sleeve that is sleeved on the outer diameters of the upper and the lower acoustic tubes. In the utility model, the rapid sealing of the acoustic tube mechanism is realized by the engagement of the gear teeth on the outer diameter of the inner spline gear sleeve and an external gear mechanism; and the novel rapid sealing mechanism has the characteristics of simple operation, quick speed, convenience and high sealing precision.
Description
Technical field
The utility model relates to the sound pipe field of sealing technology, and what relate to specifically is a kind of novel sound pipe quick-sealing mechanism.
Background technique
Existing sound pipe sealing configuration generally all adopts bolt connection mode, and the Bolt Connection sealing all is manually to carry out, install and remove very time-consumingly, efficient is low, and labor intensity is big, sealing configuration is short working life, brings very big inconvenience for maintenance and replacing parts, and might damage the sound pipe body.
Summary of the invention
In order to overcome the deficiency of above-mentioned existing sound pipe sealing configuration, the utility model provides a kind of novel quick-sealing mechanism, and it is simple and compact for structure, good seal performance, can realize automation mechanized operation.
For the attainment of one's purpose, the utility model provides following technical solution:
A kind of novel sound pipe quick-sealing mechanism, comprise sound pipe and following sound pipe, respectively with last sound pipe, the following upper spline, time spline that directly link to each other of sound pipe, O RunddichtringO about being arranged in the internal recess of sound pipe junction, it is characterized in that, comprise that also sky is enclosed within the inner spline gear cover on the sound pipe external diameter up and down.
Feature of the present utility model is that also described upper spline is directly integrally welded with last sound pipe.
Feature of the present utility model is that also described spline down is directly integrally welded with following sound pipe.
Feature of the present utility model is that also described inner spline gear cover only at one end processes spline.
Feature of the present utility model is that also described inner spline gear cover external diameter processes the gear teeth.
The beneficial effects of the utility model are that the spline tooth about the spline that inner spline gear puts can pass easily on the spline is realized the quick mounting or dismounting of inner spline gear cover; The gear teeth on the inner spline gear cover external diameter externally drive of gear mechanism are realized quick rotation down, the angular range that rotates can be finished by automatic detection and control system as required, saved the Butt sealing time of sound pipe mechanism up and down greatly, alleviate labor strength, improved working efficiency and sealed precision.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the novel sound pipe quick-sealing of the present invention mechanism.
As shown in drawings, 1 is upper spline, and 2 is the O RunddichtringO, and 3 is last sound pipe, and 4 are following sound pipe, and 5 is the inner spline gear cover, and 6 are following spline.
Embodiment
In Figure of description 1, the external diameter that the internal diameter of upper spline (1) and last sound pipe (3) have groove one end is welded as a whole, and following spline (6) is welded as a whole with the external diameter that following sound pipe (4) has groove one end; O RunddichtringO (2) is embedded in the groove of sound pipe (3) and following sound pipe (4) joint; End at the inner spline gear cover processes spline, and the spline tooth on the number of teeth of spline and size and upper spline and the following spline is just the same; The internal diameter sky of inner spline gear cover (5) is enclosed within on the external diameter of sound pipe (3) and following sound pipe (4), processes the gear teeth on inner spline gear cover (5) external diameter, so that realize engagement driving with outer gear mechanism (not drawing among the figure).
Claims (5)
1. novel sound pipe quick-sealing mechanism, comprise sound pipe and following sound pipe, respectively with last sound pipe, the following upper spline, time spline that directly link to each other of sound pipe, O RunddichtringO about being arranged in the internal recess of sound pipe junction, it is characterized in that, comprise that also sky is enclosed within the inner spline gear cover on the sound pipe external diameter up and down.
2. novel sound pipe sealing mechanism according to claim 1 is characterized in that: described upper spline is directly integrally welded with last sound pipe.
3. novel sound pipe sealing mechanism according to claim 1 is characterized in that: described spline down is directly integrally welded with following sound pipe.
