Embodiment
Below in conjunction with accompanying drawing, technological scheme of the present invention is elaborated.
Embodiment 1
Be gripping jaw type pipeline connection fastener of the present invention as Figure 1-4, comprise joint 10 and compressing member 20, several jaws 12 that joint 10 comprises annular base 11 and is distributed on annular base 11; It is round table-like that the several jaws 12 be distributed on annular base 11 arrange formation; The longitudinal cross-section of jaw 12 is right-angled trapezium, and the outer side surface of jaw is with externally threaded plane of inclination 13, leaves gap 14 between adjacent two jaws.
Compressing member 20 is a pipe fitting, and the outer wall of this pipe fitting is cylinder A21, and inwall includes the conical surface 22 of the internal thread adapted with the outside thread of jaw outer side surface.
The gradient of the described conical surface is greater than described plane of inclination gradient.
Gripping jaw type pipeline connection fastener of the present invention, jaw 12 outer side surface is with outside thread, jaw is arranged in truncated conical shape, compressing member 20 is enclosed within the round platform that jaw 12 is arranged in, internal thread is provided with in compressing member 20, screw with the outside thread of jaw 12 outer side surface, when compressing member 20 is enclosed within joint 10, as shown in Figure 5, the lower end of the inwall of compressing member 20 contacts with the top line of jaw 12, then joint 10 maintains static, rotatably compress part 20, compressing member 20 is close to joint 10 one end, now, owing to being greater than the gradient of jaw plane of inclination by the gradient of compressing member 20 inwall, the sidewall of compressing member 20 gives jaw 12 inside pressure, jaw 12 is sloped inwardly, along with compressing member 20 is to the increase of joint 10 end motion distance, the intilted degree of jaw 12 is also larger, jaw 12 is also transitioned into face by linear contact lay with compressing member 10 and contacts, the head end of jaw 12 is brought to together gradually, thus play the effect of fastening pipeline.
The present invention is connected and fixed pipe fitting by jaw 12, the diameter of the pipe fitting that jaw 12 can be fixed is (the upper bottom surface diameter of the round platform that jaw 12 is arranged in deducts the thickness of the jaw 12 of 2 times), and by rotatably compressing part 20, make compressing member 20 to joint 10 end close or away from, the upper bottom surface diameter of the round platform that adjustable jaw 12 is arranged in, thus the pipe fitting adapting to different-diameter.Gripping jaw type pipeline connection fastener highly versatile of the present invention.
In the present embodiment, jaw 12 is one-body molded with annular base 11, jaw 12 is equidistantly arranged in the upper surface of annular base 11, jaw 12 and the one-body molded mechanical strength enhancing joint of annular base 11, joint 10 structure is simple, production technology is simple, is convenient to produce in enormous quantities, and cost of production is low.
In the present embodiment, annular base 11 upper surface is distributed with 12 jaws 12.
In the present embodiment, the inwall of compressing member 20 comprises the cylinder B23 of upper end and the conical surface B22 of lower end; A step surface 24 is provided with between cylinder B23 and conical surface B22.
Embodiment 2
In the present embodiment, annular base 11 upper surface is distributed with 8 jaws 12, and the two bottom sides of jaw 12 is also provided with symmetrical arc groove 15(as shown in Figure 6).After the bottom of jaw 12 arranges arc groove 15, compressing member 20 applies less pressure then can make jaw 11 slope inwardly, and operation of being more convenient for, but open arc connected in star 15, add the complexity that joint is produced, increase cost of production.
Device of the present invention also comprises the fastening workpiece 30 be anchored on by compressing member 20 on joint 10; One end of fastening workpiece 30 is provided with the opening 31 adapted with cylinder A21, and opening 31 place and compressing member 20 are provided with anti-skidding assembly.Fastening workpiece 30 can be spanner etc.; Anti-skidding assembly can for being arranged at the locking teeth 32(of opening as shown in Figure 9) and be arranged at socket 25(that compressing member 20 is arranged as shown in FIG. 7 and 8).Locking teeth 32 is placed in socket 25, prevents fastening workpiece 30 from producing Relative sliding, rotating spanner 30 with compressing member, compressing member 20 can be driven easily to rotate.
In the present embodiment, compressing member 20 circumference is evenly provided with 4 sockets 25.
More than show and describe basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
