Abstract
The invention discloses a sealing structure for an elbow pipe and an exhaust pipe of an exhaust pipe waterproof device. The sealing structure comprises an elbow pipe, wherein the upper end of the elbow pipe is connected with the exhaust pipe by a locating device; the locating device comprises an inner ring and an outer ring; the outer ring is fixed in an opening of the exhaust pipe; the inner diameter of the outer ring and the outer diameter of the inner ring decrease gradually along the insertion direction of the elbow pipe; the elbow pipe is sleeved with the inner ring; the inner ring and the elbow pipe are inserted in the outer ring and are also tightly clamped by the outer ring; a plurality of annular grooves are formed on the periphery of the inner ring and a sealing ring which is protruded out of each annular groove is arranged in each annular groove; and a plurality of annular grooves are also formed on the periphery of the elbow pipe and a sealing ring which is protruded out of each annular groove is arranged in each annular groove. According to the sealing structure for the elbow pipe and the exhaust pipe of the exhaust pipe waterproof device, the annular grooves are formed on the peripheries of both the inner ring and the elbow pipe, and the sealing rings which are protruded out of the annular grooves are arranged in the annular grooves, so that sealing is realized between the elbow pipe and the inner ring and between the inner and the outer rings, and water is prevented from entering into the exhaust pipe.
Description
Technical field
The present invention relates to a kind of Water-in proof device of automobile discharge pipe, particularly the sealing configuration of bend pipe and outlet pipe in the anti-water feed apparatus of a kind of outlet pipe.
Background technique
Usually the mounting point of automobile exhaust pipe is lower, generally in the automobile chassis bottom, the face depth of water is higher than again the chassis when the casual water route of automobile process, and traditional automobile exhaust pipe can't be kept out the outlet pipe water inlet to stopping working that automobile causes, and serious will cause water inflow of the engine.
When water being arranged or have other erosion to enter in the automobile exhaust pipe, traditional automobile exhaust pipe can only wait for that ponding or erosion to the corrosion of outlet pipe, finally cause outlet pipe to scrap.
A kind of anti-water feed apparatus of ad hoc meter, preliminary imagination is that a bend pipe is set, in bend pipe, be arranged side by side many in order to the tubule of exhaust, the lower end of bend pipe is equipped with the water check valve that is inclined relative to horizontal, water check valve comprises lid and the number ball identical with tubule that is covered with mesh, ball be separately positioned on each tubule mouth of pipe the below and and the tubule mouth of pipe between leave the gap; Ball has lighter weight, can throw off the tubule mouth of pipe under the effect of tail gas air-flow or block the tubule mouth of pipe under the buoyancy of water effect, thereby both prevent that water from entering, and does not hinder again tail gas to discharge.
The bend pipe upper end links to each other with outlet pipe by positioning device, described positioning device comprises inner ring and outer ring, the outer ring is fixed in the outlet pipe mouth of pipe, and the internal diameter of outer ring, the external diameter of inner ring diminish gradually along the bend pipe direction of insertion, and inner ring is enclosed within on the bend pipe, inner ring, bend pipe are inserted in the outer ring and by the outer ring and tighten, but find in the practice that sealing is good not, between bend pipe and the inner ring, have a little gap between inner ring and the outer ring, water still can enter into wherein.
Summary of the invention
The present invention has overcome above-mentioned the deficiencies in the prior art, provides a kind of anti-sealing to enter into the interior bend pipe of outlet pipe and the sealing configuration of outlet pipe, and the sealing structure is the important component part in the anti-water feed apparatus of outlet pipe, has played the effect of water-based sealing.
Technological scheme of the present invention is achieved in that
The sealing configuration of bend pipe and outlet pipe in the anti-water feed apparatus of a kind of outlet pipe, comprise bend pipe, the bend pipe upper end links to each other with outlet pipe by positioning device, described positioning device comprises inner ring and outer ring, the outer ring is fixed in the outlet pipe mouth of pipe, the internal diameter of outer ring, the external diameter of inner ring diminish gradually along the bend pipe direction of insertion, inner ring is enclosed within on the bend pipe, inner ring, bend pipe are inserted in the outer ring and by the outer ring and tighten, be provided with the multiple tracks circular groove in the inner ring periphery, in circular groove, be provided with the seal ring that protrudes from circular groove; Be provided with the multiple tracks circular groove in the bend pipe periphery, in circular groove, be provided with the seal ring that protrudes from circular groove.
As preferably, on inner ring periphery, bend pipe periphery, respectively be provided with three road circular grooves.
Adopted the invention has the beneficial effects as follows of technique scheme:
The present invention is being provided with respectively circular groove on inner ring periphery, bend pipe periphery, be provided with the seal ring that protrudes circular groove in circular groove, has realized between bend pipe and the inner ring, the sealing between inner ring and the outer ring, has prevented that water from entering in the outlet pipe.
Description of drawings
Fig. 1 is the sealed structural representation of bend pipe of the present invention and outlet pipe;
Fig. 2 is the fractionation structural representation of inner ring, outer ring and bend pipe.
Embodiment
The specific embodiment of the present invention is as follows:
Embodiment: the bend pipe in the anti-water feed apparatus of a kind of outlet pipe and the sealing configuration of outlet pipe, as shown in Figure 1, bend pipe 9 upper ends link to each other like this with outlet pipe 1, bend pipe 9 upper ends link to each other with outlet pipe 1 by positioning device, described positioning device comprises inner ring 16 and outer ring 5, and outer ring 5 is installed in the outlet pipe mouth of pipe, and the external diameter of the internal diameter of outer ring 5, inner ring 16 diminishes gradually along the bend pipe direction of insertion, inner ring 16 is enclosed within on the bend pipe 9, and inner ring 16, bend pipe 9 are inserted in the outer ring 5 and by outer ring 5 and tighten.
As shown in Figure 1, 2, be provided with 3 road circular grooves 17 in inner ring 16 peripheries, in circular groove 17, be provided with seal ring 18.In addition, be provided with multiple tracks circular groove 17 in bend pipe 9 peripheries, in circular groove 17, be provided with seal ring 18.
