Abstract
The utility model provides a clamping and pressing type pipe fitting, which comprises a joint body and a clamping sleeve, wherein the rear end of the sheathing and connecting part of a pipe of the joint body is provided with an axial groove; the connecting end of the joint body is in the shape of a straight pipe; the outer surface on the connecting end is provided with a plurality of circular inserted teeth; the outer surface on the connecting end is also provided with a plurality of ring grooves; elastic-rubber sealing rings are sheathed in the ring grooves; closing rings are also arranged in the arrangement region of the circular inserted teeth of the joint body; an anti-rotation rolling tooth is arranged on each of the closing rings; the closing rings can be arranged on the rear parts of the ring grooves; a spacing washer can be arranged in the axial groove. The utility model has high anti-drawing performance and high corresponding rotation-prevention performance of pipe materials and pipe fittings. Because the spacing washer is arranged in the joint body, the sealing effect can be further improved and the electric corrosion of different metals can be prevented.
Description
Technical field
The utility model relates to a kind of pipe fitting, relates in particular to a kind of pipe fitting that flexible pipe is used that connects.
Background technique
Traditional connection pipe fitting is adopted in the connection of flexible pipes such as PEX pipe, aluminium-plastic composite pipe, connects very easily to get loose, thereby causes seepage.There is kind of solution to adopt at present and sealed groove is set, wedge shape sealing ring is housed on groove on the surface, pipe belled part of fittings body.This pipe fitting is connected with composite pipe by nut, complex structure, and construction and installation are loaded down with trivial details, use inconvenience.Another kind of solution is also arranged; it has the body of connection, core pipe, hold-down ring, seal ring, nut; through hole is arranged in the joint body; connecting end has the outside thread that cooperates with nut; be provided with the inner cone nipple orifice at an end that matches with nut; step is arranged in the joint body; be used to install aluminium-plastic composite pipe and other similar body; the core pipe is the metal thin-wall sleeve pipe; insert composite pipe connecting end inwall during connection; hold-down ring is a metal spring, is sleeved in the inner cone nipple orifice of band protecting jacket, and the structural complexity of this pipe fitting is conspicuous.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of have higher anti-drawing ability and reliable sealing effect and can prevent pipe fitting and tubing clamp-press type pipe in relative rotation more.For this reason, the utility model is by the following technical solutions: it comprises fittings body and chucking cover, the rear end, pipe belled part of fittings body is provided with axial notch, the connecting end of fittings body is straight tube shape, the connecting end outer surface is provided with many ring-type pawls, and the connecting end outer surface also is provided with several annular grooves, sheathed elastic rubber sealing ring in the annular groove, also be provided with stop ring in the zone that the ring-type pawl is set of described fittings body, stop ring is provided with rotation inhibiting and rolls tooth.
The utility model also can adopt following further technological scheme simultaneously:
Described stop ring is located at the rear portion of described annular groove.
The utility model is provided with two annular grooves, and stop ring is located between two annular grooves.
In the described axial notch spacer ring is housed.
The utility model adopts the pressurization ways of connecting, by the personality card press tool chucking cover is applied enough clamping forces and makes it produce nonvolatil plastic deformation, is connected thereby tubing is reached with pipe fitting.Owing in the zone of ring-type pawl, be provided with stop ring, the flexible pipe inner wall section is clamp-oned on the pawl of connecting end and the stop ring rolls in the tooth, make pawl and roll tooth more effectively to cooperate, thereby make the ability in relative rotation that the utlity model has higher anti-drawing ability and prevent tubing and pipe fitting.Spacer ring is housed in fittings body, sealing effect is further improved, and prevent the electro erosion of different metal.
Description of drawings

Fig. 2 is a STRUCTURE DECOMPOSITION schematic representation of the present utility model.
Embodiment
With reference to accompanying drawing.The utility model comprises fittings body 1 and chucking cover 7, the rear end, pipe belled part of fittings body 1 is provided with axial notch 9, the connecting end of fittings body is straight tube shape, the connecting end outer surface is provided with many ring-type pawls 3, the connecting end outer surface also is provided with several annular grooves 6, sheathed elastic rubber sealing ring 4 in the annular groove 6 also is provided with stop ring 5 in the zone that the ring-type pawl is set of described fittings body, and stop ring is provided with rotation inhibiting and rolls tooth.
The pipe fitting connecting end is provided with two annular grooves 6, and stop ring is located at the intermediate portion of two annular grooves.Like this, when guaranteeing to reach effect of the present utility model, make that structure of the present utility model is simpler.
In the described axial notch 9 spacer ring 2 is housed.
The utility model can be applicable to any end or the above pipe fittings such as the above demultplexer joint of straight joint, elbow connection, three-way union, threeway that connect flexible pipe of an end.
During installation, install elastic rubber sealing ring 4 and spacer ring 2 earlier, chucking cover 7 is enclosed within on the flexible pipe 8 that matches, directly insert the connecting end of fittings body 1, will tighten cover with special-purpose card pressing tongs at last and compress ne-leakage phenomenon during pressure testing.
The utility model is applicable to the connection of flexible pipes such as PEX pipe, aluminium-plastic composite pipe.
