Abstract

The utility model discloses a joint of pipeline. An inner core pipe is arranged inside a main body. A screw thread is opened at the inner wall of the main body near to the end, while the inner end of the main body takes a taper table type inclined plane which shrinks inwards. A fastening bolt is arranged at the end which is opened with a screw thread. A sealing element is arranged on the taper table type inclined plane. A gap is remained between the inner hole wall of the sealing element and the inner core pipe. When the utility model is used for connecting pipe, the jointed pipe is arranged between the inner core pipe and the sealing element. When the fastening bolt and the main body are screwed tightly, the jointed pipe is pressed towards to the inner core pipe, and is fixed and sealed. With the above structure, the utility model makes the jointed pipe bear relatively little outside force, without deformation, and also prevents the jointed pipe from aging and leaking.

Description

A kind of pipe coupling
The utility model metal conduit connection set relates in particular to a kind of pipe coupling.
Existing assembling pipe joint is threaded and is connected two kinds with non-threaded, for the pipe that can not open screw thread as aluminium-plastic composite pipe etc., the pipe joints that adopt with O RunddichtringO more, this kind pipe joint must apply external force the O RunddichtringO is pressed on realization sealing on the body when connecting, but in order to compress the O RunddichtringO, body is deformed, the plastics of extrusion are aging easily, and aging stratification will take place the aluminium-plastic composite pipe of heat processing and forming, cause the body seepage.
The purpose of this utility model is intended to overcome above-mentioned shortcoming, a kind of O of need not RunddichtringO is provided and can make the pipe coupling of the aging seepage of body.
For achieving the above object, the utility model adopts following solution: comprise main body, Sealing and lock bolt, it is characterized in that: inner core tube is set in main body; Near the end, have screw thread on the inwall of main body, and the inside end is and receives little truncated cone inclined-plane inwards; In two ends that have screw thread lock bolt is set; The tapering and the corresponding Sealing of inclined-plane tapering of outer side surface are set at place, truncated cone inclined-plane, leave between the inner hole wall of Sealing and the inner core tube and hold the slit of waiting to take over body.
Above-mentioned pipe coupling is characterized in that: described lock bolt is a threaded sleeve, offers the corresponding screw thread of screw thread with main body inner wall upper tip place on this threaded sleeve outer side wall.
Above-mentioned pipe coupling is characterized in that: described Sealing is the truncated cone cover of blooming, and a leakproof circle is established in its bottom, and the interior ring place of leakproof circle is provided with the mouth of hook, and inner hole wall is provided with the boss that a circle protrudes.
Compared with prior art, the utlity model has following advantage:
1, since the utility model when connecting body, body to be taken over is in inner core tube and Sealing is bloomed between the cover, when lock bolt and main body screw, the lock bolt squeeze sealing member cover of blooming, make it to wait to take over and press to inner core tube and fixing and sealing, it is less to wait to take over the external force of bearing like this, more need not distortion, does not wait to take over aging seepage so can not make.
2, because a leakproof circle is established in the bottom of the utility model Sealing, and the interior ring place of leakproof circle is provided with the mouth of hook, inner hole wall is provided with boss, so the utility model good airproof performance.
Below in conjunction with drawings and Examples the utility model is done and to be described in further detail.
Fig. 1, the utility model embodiment's 1 structural representation.
The sectional drawing of Fig. 2, the utility model Sealing.
Fig. 3, the utility model embodiment's 2 structural representation.
Fig. 4, the utility model embodiment's 3 structural representation.
1, main body 2, inner plastic 3, Sealing 4, inner core tube
5, lock bolt 6, wait to take over body 7, boss 8, leakproof foundation ring
Embodiment 1: as shown in Figure 1 and Figure 2, the main body 1 of present embodiment, lock bolt 5, Sealing 3 are all made of plastic, and inner core tube 4 is made with stainless steel; Be provided with screw thread near the port on main body 1 inwall, inner hole wall then is receives little truncated cone inwards, is convenient to processing when making, and main body 1 can be made the assembly parts of the outer and non-toxic plastic internal layer 2 of common plastics; Sealing 3 is the truncated cone cover of blooming, its endoporus is cylindrical and outer side surface is taper type, its size of frustum is corresponding with the circular cone of tapering and main body 1 inner hole wall, in order better to seal leakage proof, a leakproof foundation ring 8 can be established in Sealing cover 3 the bottom of blooming, and there is the mouth of hook at the interior ring place of leakproof foundation ring 8, in order to increase frictional force, bloom and also establish the boss 7 that a circle protrudes on cover 3 the inner hole wall, offer on the outer side surface of lock bolt 5 with main body 1 inwall on to open screw thread near the port place corresponding.When connection is waited to take over body 6, wait to take over body 6 and insert Sealings and bloom in the endoporus of cover 3, wait that with what be with that Sealing blooms cover 3 taking over body 6 inserts between inner core tube 4 and the main body 1, is placed in lock bolt 5 and waits to take over outside 6, and be tightened on the main body 1; When lock bolt 5 screwed and be mobile inwards, the squeeze sealing member cover 3 of blooming moved inwards, and the bloom outer side wall of cover 3 of Sealing is inwardly pressed by the extruding of main body 1 madial wall to wait to take over body 6, make it tightly to be pressed on the outer side wall of inner core tube 4, realize fastening and anti-leak.
Embodiment 2 is the pipe coupling (see figure 3) of threeway, and remaining part is with embodiment 1.
Embodiment 3 is the pipe coupling (see figure 4) of elbow, and remaining part is with embodiment 1.

Claims (3)

1, a kind of pipe coupling comprises main body, Sealing and lock bolt, it is characterized in that: inner core tube is set in main body; Near the end, have screw thread on the inwall of main body, and the inside end is and receives little truncated cone inclined-plane inwards; In two ends that have screw thread lock bolt is set; The tapering and the corresponding Sealing of inclined-plane tapering of outer side surface are set at place, truncated cone inclined-plane, leave between the inner hole wall of Sealing and the inner core tube and hold the slit of waiting to take over body.
2, a kind of pipe coupling according to claim 1 is characterized in that: described lock bolt is a threaded sleeve, offers the corresponding screw thread of screw thread with main body inner wall upper tip place on this threaded sleeve outer side wall.
