Abstract
The utility model discloses a bend pipe screwing mechanism in an inflow-prevention device of an exhaust pipe. Outer threads are arranged on the periphery of a bend pipe, a locking nut abutting against an inner ring is sleeved on the bend pipe, and the locking nut is connected with the threads of the bend pipe. Due to the fact that the locking nut is sleeved on the bend pipe, users can rotate the locking nut to push the inner ring which cannot sway or swing, and connection stability of assemblies is ensured.
Description
Technical field
The utility model relates to a kind of Water-in proof device of automobile discharge pipe, particularly the bend pipe screwing mechanism 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.
And bend pipe is fixed by positioning device with outlet pipe and links to each other, 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.Inner ring, bend pipe are inserted in the process of outer ring, because finger dynamics is uneven, so inner ring can occur, the phenomenons such as not tight are installed, causing the result is that installation is insecure.
The model utility content
The utility model has overcome above-mentioned the deficiencies in the prior art, provide a kind of in the assembling process of bend pipe, inner ring and outer ring uniform force application, stable bend pipe screwing mechanism, this bend pipe screwing mechanism belongs to the constituent element of the anti-water feed apparatus of outlet pipe, has played the effect of steady installation bend pipe.
The technical solution of the utility model is achieved in that
Bend pipe screwing mechanism in the anti-water feed apparatus of a kind of outlet pipe is provided with outside thread in the bend pipe periphery, at the bend pipe cover locking nut that props up inner ring is arranged, and locking nut is threaded with bend pipe.
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 and stopper ring props up locking nut.
Adopted the beneficial effects of the utility model of technique scheme to be:
The utility model is sheathed locking nut on bend pipe, advances inner ring by the rotation lock nut, inner ring can not produced wave, rock, and has guaranteed the stability that each assembly connects.
Description of drawings
Fig. 1 is the use view of the utility model rotary-tightening device.
Embodiment
Embodiment of the present utility model is as follows:
Embodiment: the bend pipe screwing mechanism in the anti-water feed apparatus of a kind of outlet pipe, as shown in Figure 1, be provided with outside thread in bend pipe 9 peripheries, at bend pipe 9 covers locking nut 8 is arranged, locking nut 8 is threaded with bend pipe 9, the front end of locking nut 8 props up inner ring 16, is provided with stopper ring 4 in locking nut 8 rear ends, and stopper ring 4 is threaded with bend pipe 9
During installation, bend pipe 9 is inserted in inner ring 16, then is inserted in the outer ring 5, constantly screw locking nut 8 again, to advance inner ring 16, the continuous propelling along with inner ring 16 and bend pipe 9 is tightened by outer ring 5 gradually.
After being in place, tighten again stopper ring 4, prevent that locking nut 8 from producing loosening.
Claims (2)
1. the bend pipe screwing mechanism in the anti-water feed apparatus of an outlet pipe, it is characterized in that: be provided with outside thread in the bend pipe periphery, at the bend pipe cover locking nut that props up inner ring arranged, locking nut is threaded with bend pipe.
2. outlet pipe according to claim 1 is prevented the bend pipe screwing mechanism in the water feed apparatus, and it is characterized in that: be provided with stopper ring in the locking nut rear end, stopper ring is threaded with bend pipe and stopper ring props up locking nut.
