Abstract

The utility model relates to a pipe connector, which solves the problem of good sealing property. A clamp forms an open type and is unfolded to form a stainless steel band, both ends of the stainless steel band are provided with slotted holes, both sides of the stainless steel band are provided with wrap edges and wrap angles, and the stainless steel band is surrounded on the outer circular wall of a gum cover, both the two ends of the stainless steel band are respectively wound outwards to form an ear ring, and a rolling shaft with a screw hole and a rolling shaft with a perforating hole are respectively penetrated into the ear ring. A screw bolt is screwed in the screw hole of the rolling shaft with a screw hole through the perforating hole of the rolling shaft with a perforating hole to tightly hoop the hoop on the gum cover for connecting pipes.

Description

Stainless steel lathe dog formula pipe connecting device

The utility model relates to pipe connecting component.

The inventor once had " flexible hooped type drain cast iron pipe spare connection set " in design in 1996, and application has obtained Chinese patent, this design has advantages such as sealing, antidetonation and easy accessibility, through application in recent years, the inventor on the basis that keeps original advantage, mainly is that portability, versatility and sealing aspect have been done further improvement again to this design.For example, existing procucts as shown in Figure 1, clip C when clip C two ends locks, is meeting the A of inner edge place of subsides by locking element B, to the coupling mechanism force of cushion rubber D weakness relatively, the dead point promptly occurs, it is not enough that sealing is still disliked.

The purpose of this utility model provides a kind of stainless steel lathe dog formula pipe connecting device of better tightness.

The purpose of this utility model is achieved in that stainless steel lathe dog formula pipe connecting device, it is by gum cover, clip, the perforation axis of rolling, the screw axis of rolling and bolt constitute, it is characterized in that: clip is a Stainless Steel Band when being the open type expansion, its two end part are provided with slotted hole, both sides are provided with bound edge and cornerite, and on gum cover cylindrical wall, then outwards reel respectively and constitute the ear circle in its two ends, the screw axis of rolling and the perforation axis of rolling penetrate the ear circle respectively, bolt through the perforation axis of rolling perforation be screwed into the screw axis of rolling screw and with the clip lock ring on gum cover, the bound edge of clip encases the gum cover dual-side, and cornerite encases each two ends of the screw and the perforation axis of rolling.

Above-mentioned design, when each end of two pipe fittings inserts gum cover respectively and remains on the same axis, tight a bolt, the two pipe fittings lock ring can be coupled together, and the screw axis of rolling has the function of nut, and itself and the perforation axis of rolling can be adjusted movement angle automatically in the ear volume that clip constitutes when tighting a bolt, can make so-called " dead angle " to eliminate bottom line, thereby reach the effect of better tightness.

Be described further again below by accompanying drawing, embodiment.

Fig. 1 has the fastening schematic representation of hooped type pipe connecting device;

Fig. 2 the utility model composite construction schematic representation;

Organigram when Fig. 3 the utility model clip partly launches;

Fig. 4 the utility model gum cover organigram;

Fig. 5 the utility model screw socket axis of rolling organigram;

Fig. 6 is the side view of Fig. 5;

Fig. 8 is the side view of Fig. 7.

As Fig. 2, shown in 3: the utility model is by gum cover 1, clip 2, the perforation axis of rolling 3, the screw axis of rolling 4 and bolt 5 constitute, it is characterized in that: clip 2 is a Stainless Steel Band when launching for open type, its two end part are provided with slotted hole 6, both sides are provided with bound edge 7 and cornerite 8, and on gum cover 1 cylindrical wall, then outwards reel respectively and constitute ear circle 9 in its two ends, 9 ', the screw axis of rolling 4 and the perforation axis of rolling 3 penetrate ear circle 9 respectively, 9, bolt 5 through the perforation axis of rolling 3 perforation 10 be screwed into the screw axis of rolling 3 screw 11 and with clip 2 lock rings on gum cover 1, the bound edge 7 of clip 2 encases gum cover 1 dual-side, cornerite 8 encases the screw and the perforation axis of rolling 4, each two ends of 3, wherein, clip 2 inner edges are provided with liner plate 12, are provided with beading 13 on the liner plate 12 again.So that to gum cover 1 fastening applying more, stressed better, guarantee that so-called " dead angle " reaches elimination.

As shown in Figure 4: wherein, gum cover 1 inwall central authorities are provided with the positioning table 14 of two connection pipe fitting end faces, and positioning table 14 is upper and lower respectively to be provided with double-deck water seal line 15.

Shown in Fig. 5～8: wherein, screw rolls hole axle 4 and establishes two screws 11, and the perforation axis of rolling 4 is established two perforation 10, and respectively with bolt 5 locking clips 2.Screw, the perforation axis of rolling 4,3 are all established longitudinal hole 16, with weight reduction.

Therefore the utility model is better tightness not only, and in light weight, easy accessibility not only can be used for cast iron tube or other pipe fittings, comprises that the connection of pipe fittings such as straight tube, elbow, threeway all can be used, have bigger versatility, have bigger shock resistance again, be applicable to various buildings.
