Abstract

A middle and low voltage pipeline the contact site of a connecting piece and a hoop sheet is a plane, and the upper part end head surface of the connecting piece bears traction force to press the lower part end head surface by the traction force. A screw is arranged in the connecting piece, and the end head part is made into coniform to match with a bevel of the connecting piece. A circular hoop sheet is punched with a spiral line, and one end of the spiral line penetrates through the connecting piece to contact a bottom plate to engage with the screw. The utility model has the advantages that an original force bearing sheet is cancelled, the material is saved, the cost is reduced, the screw is engaged with the hoop sheet tightly, the engagement number of the screw and the hoop sheet is added, and the torque force born by each teeth is decreased. Traction force suffering points at both end head surfaces of the connecting piece are exchanged, even a weld spot is broken, and the chucking action of the throat hoop for a pipe joint is not influenced.

Description

Arrangement for connecting hoses

The utility model relate to a kind of in, soft on the low pressure pipeline, when hard tube is connected the chucking usefulness the larynx hoop.

In known technology, this case claimant once on May 25th, 90 to Patent Office of the People's Republic of China applied for application number that name is called the larynx hoop be 9020688.3 and authorize utility model patent on April 3rd, 91, its structure is made up of screw, hoop sheet, link and load sheet.The patented product has passed through and has been installed in on-the-spot the use, to machinery, traffic, irrigate, soft on the pipeline in the industry such as fire-fighting and air-conditioning, chucking has shown the advantage that is proposed as in the application documents significantly after the connection between the hard tube, but practice shows, also there is certain deficiency in the patented product, because the load termination of screw is the plane, with the engagement of hoop sheet the time, stressed back and influence the intermeshing degree of depth, because link is a circular arc with hoop sheet contact position, screw has only seldom several teeth with the total number of teeth in engagement of hoop sheet, so the stressed tooth portion stressing conditions that particularly binds round sheet of tooth portion is bad; Because the two ends women's head-ornaments of link, termination, its underpart face is subjected to pulling force, therefore snaps in weldering place of two ends millet cake, and the patented product just can not play snap action, and will more renew.

The purpose of this utility model is to overcome the deficiency of known technology and a kind of follow-on larynx hoop of providing.

The purpose of this utility model realizes by following measure:

The bottom of link and hoop sheet contacted position change the plane into by circular arc, the two ends women's head-ornaments of link are subjected to pulling force to change the upper end women's head-ornaments into by the lower end women's head-ornaments and prolong that end to termination, the top face hook that is shaped on hook mouthful, lower end women's head-ornaments on the plane is only located, the two ends millet cake is welded into one; The threaded termination of screw is made taper shape for being complementary with the link inclined-plane into by tack; Cancellation load sheet.

Advantage of the present utility model is to cancel original load sheet, has saved raw material and has reduced cost; Because screw head coning, with after link contact reinforcing, screw has a downforce at screw, makes screw and the engagement of binding round sheet more fit; Link changes the plane with hoop sheet contact position into by circular arc, has increased the total number of teeth in engagement of hoop sheet and screw, has reduced the torsion that bears of each tooth; Changed the design of the two ends women's head-ornaments of link, make the upper end women's head-ornaments be subjected to pulling force and can be stressed after compressing the lower end surface, both be the weldering of two ends millet cake unsolder, do not influence the utility model to connecting the snap action of tube head yet.

Description of drawings:

Fig. 1 is embodiment's general assembly schematic representation provided by the utility model;

Fig. 2 is that the A of Fig. 1 is to schematic representation;

Fig. 3 is the larynx hoop embodiment with three hoop formulas.

In conjunction with the accompanying drawings the embodiment who is provided is described in further detail:

The bottom that is bent into similar trapezoid shaped housing with sheet metal becomes the termination face on the women's head-ornaments top, two ends on plane to prolong to have on the plane 4 hook mouthful, the end of lower end women's head-ornaments 5 is to upper tip face hook mouthful place, have gap 6 on the housing one end inclined-plane that the two ends millet cake is welded into one, the other end near the inclined-plane of bottom plane be shaped on the link 3 of opening 7, screw thread one termination is housed in the housing of link makes the conical screw 1 that is complementary with the housing inclined-plane, making a circular end punching out with sheet metal has helical, and pass the link opening, horizontal its termination, back that is meshed with screw on the bottom plane is exposed another termination outside the housing gap and is made hook solid and be articulated in hoop sheet 2 on the hook mouth of link.

The utility model can be made 1,2,3,4 or 5 hoop sheet, has and bind round corresponding screw of quantity that sheet is complementary and the link that corresponding quantity screw can be housed.

Accompanying drawing 3 provides the larynx hoop embodiment that 3 hoop sheets are arranged, and its structure just repeats no more.

Claims

1, a kind of larynx hoop, it is made up of screw, hoop sheet and link, the bottom that it is characterized in that link and the contacted position of hoop sheet are the plane, the two ends women's head-ornaments upper end women's head-ornaments of link prolong the face hook mouthful place, end to termination, top that is shaped on hook mouth, lower end women's head-ornaments on the plane, the two ends millet cake is welded into one, and the taper shape that is complementary with the link inclined-plane is made in the threaded termination of screw.
