It refer to shown in Fig. 1-4, in embodiment, a kind of run-resistant conduit coupling, including tube body 100, cushion rubber 200 and pressure
Tight part 300.One end of the tube body 100 is provided with contraction flow region 110, several notches 111 are offered on the contraction flow region 110,
111 spaced set of notch balances the intensity between the two neighboring contraction flow region 110 on the contraction flow region 110.It keeps away
Exempt from intensity unevenness occur, cause the situation of part partial intensities surplus easy to break.The contraction flow region 110 is close to the tube body 100
One side is provided with first connecting portion 120.
In embodiment, the compressing member 300 is the tubular of both ends open, and the internal diameter of the compressing member 300 is away from described
It is gradually reduced on the direction of tube body 100,300 madial wall of compressing member is provided with second connecting portion 310.
In actual use, during docking, the cushion rubber 200 is sheathed on one end of pipeline X to be docked, the pipeline to be docked
One end that X is arranged with the cushion rubber 200 is inserted into inside the contraction flow region 110, and the compressing member 300 is sheathed on the contraction flow region
On 110, the cooperation of the first connecting portion 120 and the second connecting portion 310 realize described in pipeline X to be docked fixation.Due to
The internal diameter of the compressing member 300 is gradually reduced on the direction away from the tube body 100, in the first connecting portion 120 and institute
When stating the cooperation of second connecting portion 310, the small one end of 300 internal diameter of compressing member can compress the contraction flow region 110, the contraction flow region
110 increase the frictional force to the pipeline X to be docked, after the completion of preventing docking, the pipe by squeezing the cushion rubber 200
The slippage of body 100 and the pipeline X to be docked.
It please refers to Fig.4, in embodiment, several ring packing teeths 210 is provided on the inner surface of the cushion rubber 200.Institute
Ring packing teeth 210 is stated for when the contraction flow region 110 squeezes the cushion rubber 200, can increase the cushion rubber 200 with it is described
The contact area of pipeline X to be docked, and then increase frictional force of the cushion rubber 200 with the pipeline X to be docked.The annular is close
Sealing tooth 210 includes first surface 211 and second surface 212, and the first surface 211 is tilted towards the direction of the tube body 100
It sets, the second surface 212 is perpendicular to the inner surface of the cushion rubber 200.
The direction of the first surface 211 towards the tube body 100 is obliquely installed, and can facilitate the pipeline X to be docked
It is inserted into inside the cushion rubber 200.The second surface 212 is used to support described first perpendicular to the inner surface of the cushion rubber 200
Surface 211 makes the first surface 211 fit closely in the surface of the pipeline X to be docked, and the pipeline X to be docked is produced
Raw certain pressure, plays the role of increasing friction force.The close tooth 210 of annular can also prevent the water in the tube body 100
Leakage and odor dispersion.
In embodiment, the cushion rubber 200 is provided with the first annular projection 220, and first annular projection is arranged on institute in 220 weeks
The outer surface of cushion rubber 200 is stated, and is set close to the pipeline X to be docked, the outer diameter of first annular projection 220 is more than described
The internal diameter of contraction flow region 110 and the outer diameter for being less than the contraction flow region 110.During docking, first annular projection 220 can be stuck in
The edge of the contraction flow region 110, plays the role of /V, such as the 100 rectangular shape of tube body, then first annular projection
220 can prevent that the pipeline X insertions the to be docked tube body 100 is too deep, and influence the circulation area of other passages.As described in
Tube body 100 does not have turning, then first annular projection 220 can prevent the pipeline X to be docked to be inserted into the tube body 100
Situation too deep, that piping cost is caused to waste.
In embodiment, the cushion rubber 200 is provided with the second annular projection 230, and second annular projection is arranged on institute in 230 weeks
The outer surface of cushion rubber 200 is stated, and is set close to first annular projection 220.Second annular projection 230 is used to increase institute
State the outer diameter of cushion rubber 200 so that the contraction flow region 110 can be squeezed preferably and fix the cushion rubber 200.Increase the glue
The outer diameter of circle 200 is the opposing force increased between the cushion rubber 200 and the contraction flow region 110, that is, increases the contraction flow region
The pressure of pipeline X to be docked, increasing friction force described in 110 pairs.
It please refers to Fig.1, in embodiment, several reinforcing ribs is equidistantly provided on the madial wall of the contraction flow region 110
112.The reinforcing rib 112 is used to enhance the intensity of pipeline between two neighboring notch 111, and it is too low and occur to avoid the occurrence of intensity
It is easy to the situation for fractureing or deforming.In the present embodiment, the thickness of the reinforcing rib 112 is along close to the pipeline X's to be docked
Direction is gradually reduced.The reinforcing rib 112 of thickness change can ensure the reinforcing rib 112 close to the one of the tube body 100
The intensity at end, and can guarantee elasticity of the reinforcing rib 112 close to one end of the pipeline X to be docked so that the contraction flow region
110 are easy to tighten, and facilitate installation.
It please refers to Fig.1 and Fig. 3, in embodiment, the first connecting portion 120 is the outer spiral shell being arranged on the tube body 100
Line, the second connecting portion 310 are the internal thread for the madial wall for being arranged at the compressing member 300, pass through thread fitting, Ke Yijing
The relative position of the compressing member 300 and the contraction flow region 110 is really controlled, i.e., accurately controls the contraction journey of the contraction flow region 110
It is excessive and pipeline X dock is made to occur rupturing or pressure is too small and pipeline X to be docked described in making to avoid the occurrence of pressure for degree
The situation of slippage is susceptible between the tube body 100.
Above description is merely a prefered embodiment of the utility model, is not intended to limit the utility model, for
For those skilled in the art, various modifications and changes may be made to the present invention.It is all in the spiritual and former of the utility model
Within then, any modifications, equivalent replacements and improvements are made should be included within the scope of protection of this utility model.
