Abstract
The utility model relates to pipe accessories, concretely an anti-leaking anti-cracking internal-connection screw head with water leakage proof and anti-cracking function of the pipe accessories, comprising a metal connection-piece sleeve, a socket pipe segment and an external connection pipe segment, wherein the metal connection piece imbedded into the internal-connection screw head near to one end of the socket pipe segment and an annular L-shaped groove extends along the pipe center line direction and an annular elastic gasket is imbedded between the groove and the metal connection piece. The advantages of the utility model are that: the groove part and elastic gasket are added on the internal-connection screw head, so as to effectively prevent the embedding piece in the accessories from cracking, avoid water leakage and prolong the service life; in addition, the external connection is prolonged to be a long pipe segment and the internal-connection screw head is changed from the pipe accessories into pipe.
Description
Technical field
The utility model relates to a kind of pipe fitting accessory, specifically refer to a kind of have anti-leak, anti-pipe fittings cracking function in connect screw terminal.
Background technique
Connect screw terminal in the prior art as shown in Figure 1, be usually used in being connected being connected of pipeline and metallic conduit etc., but in the actual using process, because influences such as the various factors such as the temperature difference, hydraulic pressure, corrosion, in when connecing screw terminal and being connected with the external pipe accessory, happen occasionally connect not firm, leak even cracking phenomena.
In addition, it is excessive to produce between required linking pipeline and the metallic conduit distance sometimes, and it is not enough to connect screw terminal length in causing, thereby pipeline is connected and will increases accessory, causes the wasting of resources, and cost improves.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, provides in a kind of leakproof anticracking and connects screw terminal.
The purpose of this utility model realizes being finished by following technological scheme:
Connect screw terminal in a kind of leakproof anticracking, by metal connecting piece sleeve pipe, bellmouth pipeline section with outreach pipeline section and form, in this, connect the embedded metal connecting piece of screw terminal near bellmouth pipeline section one end, stretch out a ring-type " L " type draw-in groove toward the pipe centerline direction, between described draw-in groove and metal connecting piece, be embedded with an annular resilient pad.
Above-mentioned annular resilient pad is higher than described ring-type " L " type draw-in groove at the height of pipe centerline direction.
In connect screw terminal the pipeline section that outreaches be a long tube section, described long tube section connects the bellmouth pipeline section and is integrative-structure.
The utility model has the advantages that connecing screw terminal in the utility model has increased draw-in groove part and resilient pad, can effectively prevent the inserts cracking in the accessory, stop to leak, increase the service life; To outreach in addition pipeline section elongate be a long tube section after, in connect screw terminal and can become tubing from pipe fittings and use.
Description of drawings
Fig. 1 connects the screw terminal sectional view in the prior art;
Fig. 2 connects the screw terminal sectional view in the utility model.
Embodiment
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
Label 1-7 representative is to outreach pipeline section 1, bellmouth pipeline section 2, metal connecting piece sleeve pipe 3, metal connecting piece 4, long tube section 5, draw-in groove 6, resilient pad 7 among the accompanying drawing 1-2.
Connect screw terminal in the prior art as shown in Figure 1, be usually used in being connected being connected of pipeline and metallic conduit etc. as pipe fittings.In connect screw terminal mainly by metal connecting piece sleeve pipe 3, bellmouth pipeline section 2 with outreach pipeline section 1 three parts and form, the internal thread by embedded metal link 4 is connected with the external pipe accessory.
In the actual using process because influences such as various factors such as the temperature difference, hydraulic pressure, corrosions, in when connecing screw terminal and being connected by metal connecting piece 4 internal threads with the external pipe accessory, the time have connection not firm, leak even the cracking phenomena generation.
Accompanying drawing 2 connects the screw terminal sectional view in the utility model.In the present embodiment, as shown in Figure 2,, go out a cross section toward pipe centerline direction stretching, extension shape and be the circular draw-in groove 6 of " L " type, between draw-in groove 6 and metal connecting piece 4, be embedded with an annular resilient pad 7 end of metal connecting piece 4 near bellmouth pipeline section 2.
When the external pipe accessory is connected with the metal connecting piece internal thread, first contact resilient pad 7 in the precession process, resilient pad 7 is squeezed, and makes firm, the tight connection between metal connecting piece 4 and external pipe accessory and the draw-in groove 6.The precession of external pipe accessory then connects and puts in place after contact " L " type draw-in groove 6.
During design, annular resilient pad 7 should be a little more than ring-type " L " type draw-in groove 6 at the height of pipeline water (flow) direction, leaves the certain extrusion space of resilient pad 7.The pipe fittings contact that connects of design closely and because the existence of " L " type draw-in groove 6, has been strengthened the muscle position of metal connecting piece, more resistance to compression like this; The existence of " L " type draw-in groove 6 has then played the buffer function when to a certain degree being stressed, make connect in the utility model screw terminal connect firm, anti-ly leak, anti-cracking.
In addition in actual use, it is excessive to produce between required linking pipeline and the metallic conduit distance sometimes, and in to connect screw terminal length not enough, thereby pipeline is connected and just needs to increase accessory, causes the wasting of resources, cost improves.As seen from Figure 2, in the present embodiment, the bellmouth of conventional pipelines accessory partly elongated become tubing, connecing screw terminal in just will be very short, to outreach that pipeline section 1 elongates be a long tube section 5, and long tube section 5 connects bellmouth pipeline sections 2 and is integrative-structure.Like this, in connect screw terminal and just can use to become and be used as tubing and use by being used as pipe fittings, make it in family's fitting-out work, according to the free cutting use of size of required length, reduced with other accessory and be connected and labor hour.Reduced cost thereupon.
