The to-be-solved technical problem of the utility model is that current staple bolt is and fixes a pipe fitting and do not have and connect two pipe fittings and become a holistic effect, in order to improve its weak point, the utility model provides a staple bolt for connecting two welded pipe fittings.
In order to achieve the purpose, the utility model is realized by the following technical proposal:
the utility model provides a staple bolt for connecting two welded pipe fittings, including the double-phase semicircle casing that sets up relatively, two halves circular arc casing draws the joint to enclose through the peripheral hardware bolt and closes cyclic annular staple bolt structure, the semicircle casing is including segmental arc and the linkage segment of connection at the segmental arc both ends, all offers the through-hole that is used for alternate peripheral hardware bolt on each linkage segment, the interval is provided with the supporting shoe of being connected with peripheral hardware on the segmental arc outer wall, be provided with screw hole and locating hole on the supporting shoe, the interval is provided with the joint groove along segmental arc radian direction on the segmental arc inner wall, and arbitrary joint groove on the semicircular arc casing and the corresponding joint groove on the second half circular arc casing enclose and close cyclic annular spacing ring.
When the utility model works, a clamping groove of a semicircular arc shell is clamped with a welding pipe fitting, and the other semicircular arc shell is clamped with the same welding pipe fitting in a corresponding clamping groove, and at the moment, two semicircular arc shells fix a welding pipe fitting; the same another joint groove with half circular arc casing and another welding pipe fitting joint, correspond joint groove and same welding pipe fitting joint with another half circular arc casing simultaneously, two half circular arc casings are fixed with another welding pipe fitting this moment, will install the peripheral hardware on the supporting shoe that the arc section outer wall corresponds after fixed accomplishing.
Compared with the prior art, because the interval is provided with the joint groove along segmental arc radian direction on this staple bolt segmental arc inner wall for this staple bolt can carry out the joint with two coaxial welding pipe fittings respectively, makes two welding pipe fittings connect into a whole, and the device simple structure, convenient operation is applicable to in the industrial production, has very strong practicality.
Each clamping groove is a V-shaped groove. The V-shaped groove enables the welded pipe fitting to be more firm in clamping.
The arc-shaped section of each semi-arc shell is provided with a pin hole, and the pin hole on the arc-shaped section of one semi-arc shell and the pin hole on the arc-shaped section of the other semi-arc shell are coaxially arranged. The pin hole is arranged to enable the contact surface of the two welded pipe joints to have a wire gap, and to limit the relative rotation between the two welded pipe joints.
Each pin hole is positioned at the top of the corresponding arc-shaped section, and the supporting blocks are symmetrically arranged by taking the pin holes as centers.
And a limiting groove matched with the peripheral gasket is formed in the outer wall of the connecting section positioned on the side surface of the through hole.

Fig. 2 is a schematic view of the inner wall of the semi-arc shell.
Fig. 3 is a schematic view of the outer wall of the semi-arc shell.
In the figure: 1 semi-circular arc casing, 101 arc section, 102 linkage segment, 2 through-holes, 3 supporting shoes, 301 screw hole, 302 locating hole, 4 joint grooves, 5 pinhole, 6 spacing grooves.
Detailed Description
The technical solution of the present application will be further described and explained with reference to the accompanying drawings and embodiments.
As shown in fig. 1-3, the hoop for connecting two welded pipe fittings comprises two opposite half-arc shells 1, the two half-arc shells 1 are drawn and connected through an external bolt to form an annular hoop structure, each half-arc shell 1 comprises an arc segment 101 and connecting segments 102 connected to two ends of the arc segment 101, through holes 2 for inserting the external bolt are formed in each connecting segment 102, supporting blocks 3 connected with the external part are arranged on the outer wall of the arc segment 101 at intervals, threaded holes 301 and positioning holes 302 are formed in the supporting blocks 3, clamping grooves 4 along the arc direction of the arc segment 101 are formed in the inner wall of the arc segment 101 at intervals, and an annular limiting ring is formed by enclosing any clamping groove 4 on one half-arc shell 1 and a corresponding clamping groove 4 on the other half-arc shell 1.
