The invention relates to a hoop connector which comprises two semicircular hoops. The two semicircular hoops are opposite and wrapped on the periphery of a pipe orifice. One ends of the two semicircular hoops are hinged with each other. A connecting block is fixed at each of the other ends of the two semicircular hoops. A groove with an upper opening is reserved on each connecting block. The openings of the grooves are opposite. The hoop connector further comprises a connecting bolt and a nut. One end of the connecting bolt is disposed in any one of the grooves of the connecting blocks and is in rotatable connection with the any one of the connecting blocks. The other end of the connecting bolt is connected with the nut in a threaded manner. The connecting bolt penetrates the two opposite grooves from the rotatably connected end with any one of the connecting block and extends to connect with the nut in a threaded manner. One ends of the two semicircular hoops are hinged with each other, the other ends of the two semicircular hoops are in threading fit by the aid of the nut and the connecting bolt in rotatable connection with the connecting blocks and disposed in the grooves, and accordingly, the two semicircular hoops are wrapped on the periphery of a pipe orifice, airtightness is high, and the hoop connector is convenient to mount and demount.
Description
Technical field
The present invention relates to a kind of link for being connected pipeline, it is particularly related to a kind of shroud ring link.
Background technique
At present, in Chemical Manufacture, connection between the pipeline connects more with flange basically, yet flange connects can only be with pipeline opening and pipeline opening docking, and area of contact is little, sealing is poor, but also needing a plurality of bolt connection pieces to be fixed connection, dismounting and installation are very inconvenient, therefore, in some special equipment, for example, in the NF membrane separator, flange seal can't reach requirement, directly affect the filtration of NF membrane separator and separate rear effect, simultaneously, because the deficiency of sealing increases cost of production.Therefore, the shroud ring link is widely used, for example, Chinese utility model patent ZL03278805.3 discloses a kind of Water pump shroud ring, it has comprised two and half circles, ear by two and half circle both sides interconnects, and wherein two round-meshed ears of tool on one side interconnect by inserting two axles in the ear circular hole; Two ears with elliptical aperture of another side utilize nut to connect and tighten up by inserting the screw rod in two ear elliptical apertures.Two and half circles, one end of this Water pump shroud ring adopts positioning shaft to connect, the other end adopts bolt to fix, the former obvious Shortcomings, two and half circles to break angle into two with one's hands very little, be unfavorable for the installation and removal of some special occasions shroud ring link, simultaneously in the long-term operation of breaking off with the fingers and thumb with closing, cause the loosening of this end, and the latter need to be take the former as benchmark, if the former has produced and has become flexible, two attachment holes on two ears of the latter's two and half circles are difficult to overlap, if with bolts, this end is fixedly connected with, then two and half circles are difficult to be wrapped in fully the periphery of pipeline opening, so easy formation slit causes sealing relatively poor.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, and a kind of shroud ring link is provided, and improves the sealing of pipeline joining place.
For solving above technical problem, the present invention takes following technological scheme:
A kind of shroud ring link, it comprises two semicircle shroud rings that are oppositely arranged and are used for being wrapped in the pipeline opening periphery, one end chain connection of two semicircle shroud rings, particularly, the other end of two semicircle shroud rings is fixed with respectively contiguous block, be equipped with the groove of opening upwards on two contiguous blocks, and the notch of groove arranges in opposite directions, the coupling bar that the shroud ring link comprises also that an end is arranged in the groove of any one contiguous block and is rotationally connected with contiguous block, with the nut that the coupling bar the other end is threaded, end passes two grooves that are oppositely arranged to coupling bar and extension is threaded with nut from being rotationally connected with contiguous block.
Preferably, the two opposite side walls of the groove that is rotationally connected with coupling bar one end is provided with positioning hole, and coupling bar is provided with the locating column that matches with positioning hole, and coupling bar rotates around the center line of locating column and is arranged in the groove.
Preferably, described nut comprises the attachment cap that is threaded mutually with coupling bar and is fixed on the other end of attachment cap for the regulating handle of convenient adjusting attachment cap and coupling bar degree of tightness.
Further, described regulating handle is provided with and is convenient to the adjustment hole that regulating handle is regulated.
Because the enforcement of above technological scheme, the present invention compared with prior art has following advantage:
Two semicircle shroud ring one ends of shroud ring link of the present invention adopt chain connection, the other end is by being arranged on the coupling bar that is rotationally connected with contiguous block in the groove and the screw-thread fit of nut, two semicircle shroud rings are wrapped in the periphery of pipeline opening, sealing is strong, and mounts and dismounts very convenient.
Description of drawings
The present invention will be further described in detail below in conjunction with accompanying drawing and concrete mode of execution.
Fig. 1 looks schematic diagram for the master according to shroud ring link of the present invention;
Fig. 2 is according to looking schematic diagram in the left side of shroud ring link of the present invention;
Wherein: 1, semicircle shroud ring; 2, contiguous block; 20, groove; 200, positioning hole; 3, coupling bar; 30, locating column; 4, nut; 40, attachment cap; 41, regulating handle; 410, adjustment hole.
Embodiment
Such as Fig. 1 and shown in Figure 2, the shroud ring link of the present embodiment comprises two semicircle shroud rings 1 that are oppositely arranged and are used for being wrapped in the pipeline opening periphery, one end hinge of two semicircle shroud rings 1 is connected, the other end of two semicircle shroud rings 1 is fixed with respectively contiguous block 2, be equipped with the groove 20 of opening upwards on two contiguous blocks 2, and the notch of groove 20 arranges in opposite directions, and the shroud ring link also comprises for the link that connects two semicircle shroud rings 1.
The above-mentioned link that is used for connecting two semicircle shroud rings 1 mainly comprises and is arranged on the coupling bar 3 that is rotationally connected with contiguous block 2 in the groove 20 and the nut 4 that is threaded with coupling bar 3 the other ends, wherein coupling bar 3 has much with the mode that contiguous block 2 is rotationally connected, be provided with positioning hole 200 by the groove 20 at contiguous block 2 in this example and coupling bar 3 ends are provided with the locating column 30 that matches with positioning hole 200, end with coupling bar 3, by cooperating of locating column 30 and positioning hole 200, so that coupling bar 3 is arranged in the groove 20 rotationally around the hole heart line of two positioning holes 200; In addition, the nut 4 that is threaded with coupling bar 3 the other ends, in this example, the nut 4 that adopts comprises the attachment cap 40 that is threaded with coupling bar 3, the regulating handle 41 that is fixedly connected with attachment cap 40 the other end, attachment cap 40 wherein adopts the most frequently used nut in related domain, regulating handle 41 is to be located on the coupling bar 3 for more convenient attachment cap 40 is twisted, the regulating handle 41 that adopts in this example is provided with adjustment hole 410, like this so that under special circumstances, for example, in the equipment of complexity, adopt and to tighten equipment can't smooth and easy work the time, pass adjustment hole 410 by simple hitching post, can regulate two elasticities between the semicircle shroud ring 1.
