Description

Bond ring of two-way wedge joining

The utility model relates to a kind of device of tightening that is used to connect tubing, relates to a kind of bunching ring or rather.

Traditional bunching ring that is used to connect tubing, the general wedge joint mode that adopts makes up, promptly mold the jointing end face that protrudes out in the locking part both sides, then correspondence is offered the yi word pattern slotted eye on the connecting end of bunching ring body, directly finishes wedging with body in-line slotted eye from the Vertical direction bending with the jointing end face of locking part bilateral.Wedging sectional structure as shown in Figure 1, among the figure 1 be locking part, 2 for body, 3 for bolt part, 11,11 ' be respectively the bilateral jointing end face of locking part.Above-mentioned wedging result forms unidirectional wedge system.

As everyone knows, general tubing mostly is rectilinear stressed greatly, as the up-down vibration of tubing or be subjected to impact of external force etc., because the wedging direction of bunching ring is laterally to clamp, therefore vertical oppositely button is made effect in the time of can't presenting two-way wedge system under unidirectional wedge system, be that unidirectional wedge system does not tackle the wedge system combined effect that vertical external force is done the time spent, thereby the situation generation that wedging is tight so that disengaging is disintegrated is often arranged.

In addition, relatively poor because of the steadiness of the unidirectional wedge joint, the off plumb state often appears during the wedge joint, also need be adjusted, also increased the complexity of operation.

The purpose of this utility model is the bunching ring of a kind of two-way wedge joint of design, the simple in structure and wedge joint effectively firmly.

Two-way wedge joint bunching ring of the present utility model, two-way correspondence is left-hand thread mutually, even there is twin shaft also can not break away from disintegration to the effect of vertical external force.

The bunching ring of the two-way wedge joint of the present utility model comprises a bolt part, a locking part and a body, and bolt part is a bolt body of rod, is screwed in the locking part, and the in-line slotted eye is arranged on the body connecting end, it is characterized in that:

Respectively upwards extend a wedge stopping tappet on the described locking part bilateral jointing end face; Corresponding locking part wedge stopping tappet intersects vertically and offers a vertical wedge groove on the in-line slotted eye of described body connecting end.

Improvement structure of the present utility model is improved to multidirectional wedge system combination with two-way corresponding wedging, this wedge stopping tappet can form two section wedge systems space of not equal altitude and flute profile again simultaneously, connect face and interior system face and define resistance, wherein resistance connects face and also can prevent slippage in restriction wedge joint mode, and interior system face has limited the wedge stopping tappet of not equal altitude, can buckling into also simply for the convex clip orientation, wedge be formed in the wedge slot space of top adjacency, behind the complete wedging of both-end, can not disintegrate, promptly two wedge stopping tappets pin down mutually, if an end angle is arranged when being subjected to powerful external force deformation, promptly can be subjected to adjacent two jiaos crowded pining down, and the steadiness and the Security that improve the wedge joint realize the effect of tightening that easy snapping need not weld.

Further specify technology of the present utility model below in conjunction with embodiment's accompanying drawing

Address before Fig. 1 illustrates, repeat no more

Referring to Fig. 2, two-way wedge joint bunching ring comprises locking part 1, body 2 and bolt part 3.

Locking part 1 bilateral jointing end face 11,11 ' on respectively mold upwardly extending wedge stopping tappet 110,110 '.Intersect vertically on the in-line slotted eye 21 of body 2 connecting ends and offer a vertical wedge groove 22, define a resistance by the space parallax of in-line slotted eye 21 and vertical wedge groove 22 and meet system face 22B in face 22A and, make the simple and easy and restriction wedge joint mode of the wedge joint.

The wedge joint process of above-mentioned bunching ring is: at first with locking part 1 bilateral jointing end face 11,11 ' bend inwards into the vertical plane state, wedge stopping tappet 110,110 ' relative corresponding with vertical wedge groove 22 on body 2 connecting ends, when locking part 1 bilateral jointing end face 11,11 ' when inwardly clamping, two wedge stopping tappets 110,110 ' in vertical wedge groove 22 become complementary fill wedge system (referring to Fig. 3 by being embedded in outward and inwardly, Fig. 4), be different from traditional directly vertical wedge joint mode, promptly connect face 22A and wedge stopping tappet 110 by vertical wedge groove 22 formed resistances, 110 ' the height potential difference, proper vertical wedging capable of blocking, simultaneously, improving wedge joint steadiness can slippage, and forms bi-directional synchronization wedging state.Not only under horizontal force, can not disintegrate, and solid each under active force, all can not disintegrate, this be because two wedge stopping tappets 110,110 ' can blocking by the left-hand thread of vertical wedge groove 22, and when being subjected to the Vertical direction active force, resistance meets face 22A and interior system face 22B to its left-hand thread blocking, and when traditional bunching ring is made unidirectional wedging, always have the disintegration situation under directions X or Y directive effect power to take place.

Improvement structure of the present utility model is when the both-end wedging is 2-way state, when even a certain angle is slightly departed from by brute force, the variation of its angle is reacted to adjacent two jiaos rapidly, produce the tight drag of compressing of wedge system and pin down mutually, moreover because of two wedge stopping tappets 110,110 ' the wedging mode by level in abutting connection with turnover wedging when vertical, can behind four jiaos of wedge joints, become four end plumbnesss, and the problem that issuable non-perpendicular distortion and needing is adjusted in addition when getting rid of the traditional unidirectional wedge joint.

The utility model is simple in structure, and the wedge joint is convenient and firm.
