Description

A kind of pipe fitting connection component

Technical field

A kind of connection component is the utility model is related to, specifically a kind of pipe fitting connection component.

Background technology

The connection component of pipe fitting is widely used in the every field such as daily life, industrial production, in terms of the people's livelihood It is mainly used in solar energy heat collection engineering pipeline etc., current connection component is substantially added using screwed cap to be held out against ring and add The form design of sealing ring, such a design can solve the problem of pipe fitting connects to a certain extent again, but this form Shorter a period of time can only be used, and bad, the anti-high voltage intensity deficiency of sealing effectiveness be present, anti-vibration resistance is bad etc. lacks Fall into, while the also easily de- mouth when installing and using, cause the permanent damage of connection component, not only wasted component but also labor intensive into This, it is extremely uneconomical.

Utility model content

The utility model is in view of the shortcomings of the prior art, provide a kind of pipe fitting connection component.

The technical scheme that the utility model solves above-mentioned technical problem is as follows：A kind of pipe fitting connection component, including body sheet Body, O-ring, trapezoidal retainer ring, pipe fitting screwed cap, pipe, the O-ring, trapezoidal retainer ring, pipe fitting screwed cap sequentially cover respectively On pipe, the bottom opening and bore dia of the pipe fitting screwed cap are not less than the diameter of pipe, the pipe fitting screwed cap with Body body is fixed together by intermeshing thread set, is set with the pipe between O-ring and trapezoidal retainer ring There is trapezoidal circle, tapered expansion collar, the tapered expansion collar are set between the pipe upper trapezoid retainer ring and pipe fitting screwed cap Small conical surface circular diameter be less than the axis of great circle of trapezoidal retainer ring, the big conical surface circular diameter of the tapered expansion collar is more than trapezoidal solid Determine the axis of great circle of ring；The end of the body body is first to be provided with body body inverted cone surface；The pipe fitting screwed cap is close to waveform bullet The side of piece is provided with conical surface groove.

The beneficial effects of the utility model are：The utility model is simple and convenient, adds trapezoidal circle and conical expansion Enclose two critical components so that pipe fitting screwed cap is sealed to for double containment between body body, enhances sealing effect Fruit, while tapered expansion collar further increases the sealing strength between them, enhances the contact surface between pipe fitting and pipe fitting Product, improves the compressive resistance at pipe connector, while coordinates the design of body body inverted cone surface and conical surface groove, such a pipe fitting component Also further significantly improved for sealing property and anti-shake performance.

Further, waveform splinter is installed between the upper conical distensible ring of the pipe and pipe fitting screwed cap.

Beneficial effect using above-mentioned further scheme is after having installed waveform splinter additional, effectively to prevent from operating De- mouth problem in journey, while expanded with heat and contract with cold according to climate reasons, waveform splinter, for its sealing effectiveness, resistance to compression effect, antidetonation Dynamic effect etc. is more significantly and perfect.

Further, the material of the O-ring and trapezoidal circle is caoutchouc elasticity material.

Beneficial effect using above-mentioned further scheme is that caoutchouc elasticity material is flexible, can be more preferably at sealed interface Gap, sealing effectiveness is more preferable.

Embodiment

Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality It is new, it is not intended to limit the scope of the utility model.

A kind of pipe fitting connection component, including body body 1, O-ring 3, trapezoidal retainer ring 4, pipe fitting screwed cap 5, pipe 6, The O-ring 3, trapezoidal retainer ring 4, pipe fitting screwed cap 5 are sequentially sleeved on pipe 6 respectively, the bottom of the pipe fitting screwed cap 5 Perforate and bore dia are not less than the diameter of pipe 6, and the pipe fitting screwed cap 5 passes through intermeshing thread bush with body body 1 Dress is fixed together, and is set with trapezoidal circle 8, the upper trapezoid of pipe 6 on the pipe 6 between O-ring 3 and trapezoidal retainer ring 4 Tapered expansion collar 9 is set between retainer ring 4 and pipe fitting screwed cap 5, the small conical surface circular diameter of the tapered expansion collar 9 is less than ladder The axis of great circle of shape retainer ring 4, the big conical surface circular diameter of the tapered expansion collar 9 are more than the axis of great circle of trapezoidal retainer ring 4；Institute The end head for stating body body 1 is provided with body body inverted cone surface 2；The pipe fitting screwed cap 5 is provided with cone close to the side of waveform splinter 7 Face groove；Waveform splinter 7 is installed, the O-ring 3 and trapezoidal between the upper conical distensible ring 9 of the pipe 6 and pipe fitting screwed cap 5 The material of circle 8 is caoutchouc elasticity material.

With reference to Fig. 2, when pipe fitting screwed cap 5 is tightened, the stress of waveform splinter 7 extruding taper distensible ring 9, in trapezoidal retainer ring In the presence of 4, tapered expansion collar 9 will be forced taper by a horizontal direction and the power of vertical direction, the power of vertical direction Distensible ring 9 tightly extrudes pipe 6, so as to reach the purpose that stable body body 1 and pipe 6 are not easy to thread off；Trapezoidal fixation Ring 4 extrudes trapezoidal circle 8, and body body inverted cone surface 2 gives trapezoidal circle 8 one power vertically and horizontally, vertical direction Power is used between trapezoidal circle 8 and pipe 6 seal, and the power of horizontal direction is allowed to the trapezoidal sealing enclosed between 8 and body body 1 more Firmly, the sealing that O-ring 3 is formed with body body 1 in addition, so as to generate double containment, so this connection component is more Perfect solves the defects of leak, poorly sealed.

Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in Within the scope of shield.
