Abstract
The utility model discloses a connection structure of a bend pipe and an exhaust pipe in an exhaust pipe inflow-prevention device. The upper end of the bend pipe is connected with the exhaust pipe through a location device which comprises an inner ring and an outer ring. The outer ring is fixedly installed in a pipe opening of the exhaust pipe, the inner diameter of the outer ring and the outer diameter of the inner ring are gradually reduced along the bend pipe insertion direction, the inner ring is sleeved on the bend pipe, and the inner ring and the bend pipe are inserted in the outer ring and firmly clamped by the outer ring. Due to the fact that the location device comprises the inner ring and the outer ring which are provided with conical faces which are matched, the inner ring and the bend pipe are firmly clamped by the outer ring when inserted in the outer ring, and installation and location of the bend pipe are achieved. The connection structure is convenient.
Description
Technical field
The utility model relates to a kind of Water-in proof device of automobile discharge pipe, particularly the bend pipe in the anti-water feed apparatus of a kind of outlet pipe and the linkage structure 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.But how bend pipe being linked to each other with outlet pipe is the problem that needs solve.
The model utility content
The utility model has overcome above-mentioned the deficiencies in the prior art, provide a kind of easy to connect, the firmly linkage structure of bend pipe and outlet pipe is installed.
The technical solution of the utility model is achieved in that
Bend pipe in the anti-water feed apparatus of a kind of outlet pipe and the linkage structure of outlet 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, and inner ring, bend pipe are inserted in the outer ring and by the outer ring and tighten.
In order bend pipe to be inserted in the outlet pipe and realize further location, as preferably, also cover has locking nut on bend pipe, and locking nut is threaded with bend pipe, and the front end of locking nut props up inner ring.
Loosening in order to prevent that locking nut from producing, as preferably, be provided with stopper ring in the locking nut rear end, stopper ring is threaded with bend pipe.
Adopted the beneficial effects of the utility model of technique scheme to be:
Positioning device of the present utility model comprises inner ring, outer ring, and inner ring, outer ring have the conical surface that matches, and inner ring and bend pipe are tightened by the outer ring in inserting the outer ring time, have realized installation, the location of bend pipe, and be very convenient.
Description of drawings
Fig. 1 is the linkage structure schematic diagram of bend pipe of the present utility model and outlet pipe.
Embodiment
Embodiment of the present utility model is as follows:
Embodiment: the bend pipe in the anti-water feed apparatus of a kind of outlet pipe and the linkage structure 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.
Also cover has locking nut 8 on bend pipe 9, and locking nut 8 is threaded with bend pipe 9, and the front end of locking nut 8 props up inner ring 16.Be provided with stopper ring 4 in locking nut 8 rear ends, stopper ring 4 is threaded with bend pipe 9 equally.
