Abstract

The invention relates to a pipeline joint, and in particular relates to a self-locking type quick joint. The self-locking type quick joint comprises a female joint and a male joint; a concave ring groove is formed in the upper part of the male joint; a pair of lug seats which pass through a cavity is symmetrically arranged on the sidewall of the cavity of the female cavity; a lug I is mounted on the lug seats through a rotating shaft I; an eccentric pressing head is arranged at the lower end of the lug I, and the top end of the eccentric pressing head passes through the sidewall of the cavity. The self-locking type quick joint is characterized in that the lower end of a lug II is mounted to the inner side of the lug I through a rotating shaft II; a convex clamping buckle is arranged at the lower part of the lug II, and a spring is arranged at the inner side of the medium part of the lug II; a clamping groove is formed in the upper part of the lug seat. The self-locking type quick joint is simple in structure, convenient to use, quick to connect, and firm and reliable to connect; the falling preventing rate is increased by more than 200%; the accident rate is reduced to be within 0.1%.

Description

Self locking quick connector
Technical field
The present invention relates to a kind of pipe coupling, especially relate to a kind of self locking quick connector.
Background technique
Often rapid pipe joint will be used when liquid, gas or lubricating fluid are carried.At present, but the potential safety hazards such as existing rapid pipe joint existence connection is insecure, easily get loose, mainly because the frictional force of its circular arc concave surface connected in the main arc convex surface leaning on female joint two hanger and the tool joint pin of docking with it is connected and fixed, and the size of two hanger frictional force incomplete same, in case of sharp pounding or external force just may get loose and ability of losing the job.In real work, the accident rate that gets loose of existing rapid pipe joint can reach about 35%.
Summary of the invention
Technical problem to be solved by this invention is, the defect existed for prior art and provide a kind of safe and reliable, self locking quick connector of being connected firmly.
The technical solution adopted in the present invention is: self locking quick connector, it comprises female joint and tool joint pin, the top of described tool joint pin is provided with spill annular groove, the symmetrical lifting eye seat establishing an opposed through cavity on the cavity wall of described female joint, hanger I is arranged on lifting eye seat by rotating shaft I, the lower end of hanger I is provided with eccentric pressure head, eccentric pressure head top through cavities sidewall, it is characterized in that, the lower end of hanger II is arranged on the inner side of hanger I by rotating shaft II, the bottom of hanger II is provided with outstanding buckle, the inner side at middle part is provided with spring, lifting eye seat top is provided with draw-in groove.
Circular shape packing ring is provided with in described cavity.
There are two parallel baffle plates the inner side of described hanger I, and the gap of two baffle plates is not less than the thickness of hanger II.
There is circular hole described hanger II upper end, and circular hole is built with annulus.
Described tool joint pin bottom is provided with some annular anticreep ribs.
The invention has the beneficial effects as follows: structure of the present invention is simple, easy to use, can realize connecting fast, joint connects solid and reliable, and anticreep rate improves more than 200%, and accident rate drops within 0.1%.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Wherein, 1-female joint, 2-cavity, 3-circular hole, 4-annulus, 5-hanger I, 6-hanger II, 7-baffle plate, 8-spring, 9-buckle, 10-rotating shaft II, 11-draw-in groove, 12-eccentric pressure head, 13-rotating shaft I, 14-spill annular groove, 15-lifting eye seat, 16-tool joint pin, 17-anticreep rib, 18-packing ring.
Embodiment
The embodiment provided below in conjunction with accompanying drawing further illustrates concrete structure of the present invention.
As shown in drawings, self locking quick connector of the present invention, it comprises female joint 1 and tool joint pin 16, the top of described tool joint pin 16 is provided with spill annular groove 14, the symmetrical lifting eye seat 15 establishing an opposed through cavity 2 on cavity 2 sidewall of described female joint 1, hanger I 5 is arranged on lifting eye seat 15 by rotating shaft I 13, the lower end of hanger I 5 is provided with eccentric pressure head 12, eccentric pressure head 12 top through cavities 2 sidewall, it is characterized in that, the lower end of hanger II 6 is arranged on the inner side of hanger I 5 by rotating shaft II 10, the bottom of hanger II 6 is provided with outstanding buckle 9, the inner side at middle part is provided with spring 8, lifting eye seat 15 top is provided with draw-in groove 11, circular shape packing ring 18 is provided with in described cavity 2, the inner side of described hanger I 5 has the gap of two parallel baffle plate 7, two baffle plates 7 to be not less than the thickness of hanger II 6, there is circular hole 3 described hanger II 6 upper end, and circular hole 3 is built with annulus 4, described tool joint pin 1 bottom is provided with some annular anticreep ribs 17.
Using method and principle: when connecting pipe or pipe, be first fixedly connected with tool joint pin 16 and female joint 1 respectively by pipe fitting, pinch hanger II 6 and hanger I 5 with hand, buckle 9 contracts from draw-in groove 11, pulls hanger I 5 and it is opened to both sides; The spill annular groove 14 of tool joint pin 16 inserts in the cavity 2 of female joint 1, and with hand, it is merged to centre by inside for hanger I 5 pressure, eccentric pressure head 12 is pressed in spill annular groove 14, and tool joint pin 16 is firmly clamped; Hand pinches hanger II 6 and hanger I 5 again, buckle 9 is snapped in draw-in groove 11 and pins.When unloading tool joint pin and female joint, contrary operation can be carried out.The present invention improves in existing rapid pipe joint, by installing a hanger II 6 on hanger I 5, hanger II 6 designs buckle 9, hanger I 5 firmly can be fixed on the both sides of female joint when pipe fitting connects, prevent the generation that gets loose, serve the effect of insurance, the more existing raising more than 200% of anticreep, accident rate drops within 0.1%.In cavity, silicagel pad is set, seals.
