The technical solution of the utility model is: the clamp device of a kind of pipe joint, described pipe joint include with The annular outer cover of opening and be located at the sealing ring in this annular outer cover, the clamp device bag of described pipe joint Including the lug being respectively arranged on the annular outer cover of described opening both sides a pair, described lug is by annular outer cover certainly Opening part is outwards bent to form, and the end of bending part is fixedly welded on annular outer cover；Each lug curved Being symmetrically arranged with the hole, location of two axially spaced-aparts at folding respectively, hole, described location is width dimensions uniform The strip hole caused, and the length two ends of described strip hole are semicircular structure, wear respectively in each lug There is a steel pipe, wherein offer two corresponding with hole, location accordingly on a steel pipe and cross keyhole, another root Offer and position accordingly two screwed holes that hole is corresponding, described keyhole and the axially bored line of screwed hole excessively on steel pipe Be arranged vertically with the pipe axis of described steel pipe, two bolts be horizontally through the hole, location of correspondence and cross keyhole and with Described screwed hole is threaded, thus by two fastener for connection together, described steel pipe is 304 stainless steels Matter.

This utility model, on the basis of technique scheme, also includes following preferred version:

Described steel pipe is pipe.

Described bolt is the hexagon socket head cap screw of socket cap.

Described bolt and annular outer cover are steel.

Described sealing ring is quality of rubber materials.

The utility model has the advantages that: owing to the clamp device of this pipe joint of this utility model mainly uses spiral shell Bolt and round steel pipe with threaded hole are made, and its simple in construction makes and use the most very convenient, cost Relatively low.

Accompanying drawing explanation

In order to be illustrated more clearly that the technical scheme of this utility model embodiment, in embodiment being described below The required accompanying drawing used is briefly described, and the accompanying drawing in describing below is only some enforcements of the present invention Example, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to root Other accompanying drawing is obtained according to these accompanying drawings.

Fig. 1 is the structural representation of clamp device in this utility model embodiment；

Fig. 2 is the exploded view of clamp device in this utility model embodiment；

Fig. 3 be in this utility model embodiment fastener application in the overall structure schematic diagram of pipe joint；

Wherein: 1-annular outer cover, 1a-opening, 2-clamp device, 21-lug, 22-positions hole, 23-steel pipe, 24-bolt, 25-screwed hole, 26-crosses keyhole, 3-sealing ring.

Detailed description of the invention

Below in conjunction with specific embodiment, such scheme is described further.Should be understood that these embodiments are to use It is not limited to limit scope of the present utility model in explanation this utility model.The implementation condition used in embodiment Can do adjustment further according to the condition of concrete producer, not marked implementation condition is usually in normal experiment Condition.

Fig. 1～Fig. 3 shows a specific embodiment of the clamp device of this pipe joint of this utility model, institute The pipe joint stated is for the connection of two pipelines, and it includes the annular outer cover 1 with opening 1a and is located at this Sealing ring 3 in annular outer cover.

The key improvements of embodiment is: the clamp device 2 of this pipe joint of the present embodiment includes a pair respectively Being arranged at the lug 21 on described opening 1a both sides annular outer cover 1, described lug 21 is by annular outer cover 1 Outwards being bent to form from opening part, the end of bending part is fixedly welded on annular outer cover.Each lug Bending place is symmetrically arranged with the hole, location 22 of two axially spaced-aparts respectively, and hole, described location 22 is width dimensions The strip hole of uniformity, and the length two ends of described strip hole are semicircular structure, in each lug 21 It is equipped with a steel pipe 23 (having two lugs, so has two steel pipes 23), a wherein steel respectively Offer two corresponding with hole, location accordingly on pipe 23 and cross keyhole 26 (smooth inner wall), another root steel pipe Offer two screwed holes 25 corresponding with hole, location accordingly on 23, cross the aperture of keyhole 26 slightly larger than screw thread The aperture in hole 25, the described vertical cloth of pipe axis crossing keyhole and the axially bored line of screwed hole 25 with described steel pipe 23 Putting, two bolts 24 are horizontally through the hole, location 22 of correspondence and cross keyhole and connect with described screwed hole 25 screw thread Connect, thus two steel pipes 23 are linked together.And described steel pipe 23 uses 304 stainless steels, Its corrosion resistance is strong, and structural strength is high, it is possible to ensure that the internal thread of its upper screwed hole 25 uses for a long time complete Property.
