Abstract
The utility model discloses a novel pipe fitting connector with low probabilities of ageing and water leakage. The novel pipe fitting connector comprises a body, wherein the body comprises an arc-shaped section and straight pipe sections located at two ends of the arc-shaped section; a circular boss is arranged inside each straight pipe section; a piston ring is arranged on one side, close to each end part of the body, of each circular boss; the outer wall of each piston ring is matched with the inner wall of each straight pipe section; the diameter of a through-hole in the center of each piston ring is smaller than that of a through-hole in the center of each circular boss; an internal thread is arranged on the inner wall of each the straight pipe section between each circular boss and one end of the body; and the outer wall of each internal thread is coated with a rubber layer. According to the utility model, one circular boss is arranged inside each straight pipe section; the piston ring is arranged on one side, close to each end part of the body, of each circular boss; when a pipe fitting stretches into the straight pipe sections, the end parts of the pipe fitting are in contact with the piston rings; the piston rings receive and limit the circular bosses to avoid displacement, so that the piston rings are clamped into the end parts of the pipe fitting, and the pipe fitting is prevented from leaking water from the end parts; and the outer wall of each internal thread is coated with the rubber layer, so that water leakage from a side surface can be avoided.
Description
Technical field
The utility model relates to a kind of connecting head of pipe fitting, relates in particular to a kind of aging and novel pipe fitting connecting head that leak of being difficult for.
Background technique
the connecting head of pipe fitting is very common in daily life, be used for connecting two tubes, or pipe is turned to, if but that process the joint of connecting head is bad, situation about can leak, present connecting head is all generally to be made of arcuate segment and straight length, the straight length inwall is provided with internal thread, when being connected with pipe fitting, it is generally the outside thread place's winding raw meal belt at pipe fitting, raw meal belt itself is solid not, when internal and external threads coordinates rotation, easily because of extruding and distortion damage, and the time has been grown, raw meal belt also can be aging, in addition, the raw meal belt waterproof that only is wound around by the side between pipe fitting and connecting head, waterproofing effect is bad.
Summary of the invention
The purpose of this utility model just is that providing a kind of addresses the above problem, and is difficult for aging and novel pipe fitting connecting head that leak.
to achieve these goals, the technical solution adopted in the utility model is such: a kind ofly be difficult for aging and novel pipe fitting connecting head that leak, comprise body, described body is made of arcuate segment and the straight length that is positioned at arcuate segment two ends, be provided with an annular boss in described straight length, annular boss is provided with a piston ring near a side of body end, the outer wall of described piston ring and straight length inwall coupling, the through-hole diameter at piston ring center is less than the through-hole diameter at annular boss center, straight length inwall between annular boss and body two ends is provided with internal thread, described internal thread outer wall is coated with rubber layer.
As preferably: the coaxial setting of described annular boss, piston ring and straight length.
As preferably: described piston ring adopts the spiral piston ring.
compared with prior art, the utility model has the advantage of: be provided with an annular boss in straight length, a side in the close body end of annular boss is provided with a piston ring, after pipe fitting stretches into straight length, the end of pipe fitting contacts with piston ring, and piston ring is received making of annular boss, can not be shifted, like this, just sticked into the end of pipe fitting, pipe fitting can not leaked from the end, the inwall of pipe fitting and straight length is to be threaded, so, straight length inwall between annular boss and body two ends is provided with internal thread, and the internal thread outer wall is coated with rubber layer, has certain stretchability, can avoid from the side leaking, when pipe fitting is connected defective tightness with piston ring, the water that flows out from piston ring also can be intercepted by rubber layer, the utility model waterproofing effect is fine, the through-hole diameter at piston ring center is less than the through-hole diameter at annular boss center, mainly to avoid the end of pipe fitting and the joint of piston ring to leak, the utility model is simple in structure, convenient and practical.
Description of drawings
Fig. 1 is sectional view of the present utility model;
Fig. 2 is the A partial enlarged drawing of Fig. 1.
In figure: 1, arcuate segment; 2, straight length; 3, annular boss; 4, piston ring; 5, internal thread; 6, rubber layer.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
embodiment 1: referring to Fig. 1, Fig. 2, a kind ofly be difficult for aging and novel pipe fitting connecting head that leak, comprise body, described body is made of arcuate segment 1 and the straight length 2 that is positioned at arcuate segment 1 two ends, be provided with an annular boss 3 in described straight length 2, annular boss 3 is provided with a piston ring 4 near a side of body end, the outer wall of described piston ring 4 and straight length 2 inwall couplings, the through-hole diameter at piston ring 4 centers is less than the through-hole diameter at annular boss 3 centers, straight length 2 inwalls between annular boss 3 and body two ends are provided with internal thread 5, described internal thread 5 outer walls are coated with rubber layer 6, described annular boss 3, piston ring 4 and the coaxial setting of straight length 2, described piston ring 4 adopts the spiral piston ring.
be provided with an annular boss 3 in straight length 2, a side in annular boss 3 close body end is provided with a piston ring 4, after pipe fitting stretches into straight length 2, the end of pipe fitting contacts with piston ring 4, and piston ring 4 is received making of annular boss 3, can not be shifted, like this, just sticked into the end of pipe fitting, pipe fitting can not leaked from the end, the inwall of pipe fitting and straight length 2 is to be threaded, so, straight length 2 inwalls between annular boss 3 and body two ends are provided with internal thread 5, and internal thread 5 outer walls are coated with rubber layer 6, has certain stretchability, can avoid from the side leaking, when pipe fitting is connected defective tightness with piston ring 4, the water that flows out from piston ring 4 also can be intercepted by rubber layer 6, the utility model waterproofing effect is fine, the through-hole diameter at piston ring 4 centers is less than the through-hole diameter at annular boss 3 centers, mainly to avoid the end of pipe fitting and the joint of piston ring 4 to leak, the spiral piston ring can increase and decrease the spiral number of turns as required, the pipe fitting that is fit to different length uses.
