Abstract

The utility model discloses a hard tube hoop. The hard tube hoop comprises a toothed belt, a worm, a shell and V-shaped grooves. The toothed belt is a rectangular strip belt, and a buckle inserted into the shell is formed at one end of the toothed belt; the surface of the other end of the toothed belt is fixedly connected with the inner side of the shell into a whole; the worm is inserted into the shell and makes contact with the buckle on the toothed belt to form a closed outer circle; the V-shaped grooves are two or three arcs, are evenly placed on the inner circumference of the outer circle and are fixedly connected with the toothed belt into a whole to form an inner circle. The hard tube hoop has the advantages that due to the fact that the outer circle is a worm transmission type hoop body, the V-shaped grooves of the inner circle can be held tightly in a 360-degree mode, and the V-shaped grooves enable stress of the hoop body to be evener; particularly, the hard tube connecting parts at the two ends are clamped, the performance is stable, it is guaranteed that no gas leaks, and the hard tube hoop is suitable for clamping of automobile gas circuit hard tube connection positions; the structure can be assembled overall and the hard tube hoop is simple and convenient to use.

Description

Hard tube clip

Technical field

The utility model relates to a kind of hard tube clip, particularly relates to a kind of hard tube clip that is applicable to connect automobile air path pipe fitting.

Background technique

Existing V-type groove clip is annular monomer, by bolt and nut one-way locking; When assembling, bolt need be backed out, open clip angle in accordance with regulations and be enclosed within interface.There is following defect in this clip, owing to there being angle to require screw when assembling bolt to be difficult for aligning, can cause the reject rate of 10-20%, and efficiency of assembling is low, is not suitable for production line and uses; In addition, bolt one-way locking, coupling mechanism force is inhomogeneous, and X axis power is large, and Y-axis power is little, can not realize 360 ° of evenly functions of clamping.

Summary of the invention

Technical problem to be solved in the utility model is, a kind of strong locking ability is provided, and firm stable is suitable for hard tube and is connected the hard tube clip using with hard tube connector place.

The technological scheme that the utility model adopts is: a kind of hard tube clip, comprises cingulum, worm screw, housing and V-type groove; Described cingulum is rectangular strip, and one end of cingulum is formed with the buckle inserting in housing; The other end surface and the inner side of described housing of cingulum fix as one; Described worm screw inserts in housing and contacts with the buckle on cingulum, forms the outer ring of a closed loop; Described V-type groove is two or three circular arcs, and V-type groove is evenly placed in the interior week of outer ring, and fixes as one with cingulum, forms inner ring.

Inner side welding, plug-in mounting or the riveted of described cingulum and housing are integrated.

Buckle on described cingulum is concave-convex shape, rectangular small opening or crescent shape small opening.

The material of described cingulum, worm screw, housing and V-type groove is stainless steel or straight carbon steel.

Described housing is standard, inclined to one side head and headkerchief.

The beneficial effects of the utility model are: because outer ring is scroll drive type clip, while therefore locking, can hold inner ring V-type groove tightly by 360 degree, multiple V-type grooves make clip stressed more even; Particularly clamp two ends hard tube connection part, stable performance, guarantees gas ne-leakage, is applicable to automobile air path hard tube joint clamping; This structure can realize entirety assembling, simple and convenient.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:

As shown in Figures 1 to 8, the utility model hard tube clip is to be combined by scroll drive type hoop and V-type groove, comprises, material is cingulum 10, worm screw 20, housing 30 and the V-type groove 40 of stainless steel or straight carbon steel; Described cingulum 10 is rectangular strip, and one end is formed with buckle, inserts in housing 30; The other end of cingulum 10 is smooth surface, i.e. one end of anodontia button is integrated with inner side welding, plug-in mounting or the riveted of described housing 30; Described worm screw 20 inserts in housing 30 and contacts with the buckle on cingulum 10, forms the outer ring of a closed loop; Described V-type groove 40 is two or three circular arcs, and V-type groove 40 is evenly placed in the interior week of outer ring, and is welded as a whole with cingulum 10, forms inner ring.

It is worthy of note, the buckle on the cingulum 10 in scroll drive type hoop is concave-convex shape 41, rectangular small opening 42 or crescent shape small opening 43, and different buckle structures and housing can be effectively fastening.

In working order time, hoop sleeve, on the dome of two hard tube connection parts, is turned to worm screw with inner hexagon spanner, drive cingulum to tighten up inner ring V-type groove, be clamped on the joint that hard tube two ends are dome.Worm screw is applied and tightened, and moment of torsion reaches while guaranteeing torque setting value, and V-type groove is just by the dome clamping of two hard tube connection parts, and locking leak resistance is reliable, is applicable to production line, uses pneumatic or electric fixed-torque spanner assembling, swift and convenient to operate.

The utility model hard tube clip, having solved prior art is that the locking of monomer clamp bolt can not guarantee the even locking problem in 360 °, hard tube connector place, this clip adopts double layer construction, by monomer V-type groove clip, be assembled in scroll drive type clip, 360 ° of outer rings are held V-type groove inner ring tightly, reach monomer clip 2-3 performance doubly, are more suitable at the hard tube of pipeline vibrations, high pressure, hot environment and connect and sealing.
