Abstract
The utility model relates to a loose joint for sheathing, jointing, sealing and fastening tubes, which belongs to connecting devices for tubes. The utility model is composed of a connecting body 1, snap washers 3 and nuts 2. The connecting body is a symmetrical structure and is formed by integrating an inner cylinder sleeve 7 and an outer cylinder sleeve 6. The height of the inner cylinder sleeve is higher than that of the outer cylinder sleeve, and the difference of the inner radius of the outer cylinder sleeve and the outer radius of the inner cylinder sleeve is equal to or is a bit larger than the wall thickness of a connecting tube. The outer cylinder sleeve is provided with outer screw threads used for matching the nuts. The snap washers are placed outside the connecting tube 4 and in the nuts. The utility model can realize fastening and sealing connection without processing screw threads to the tubes.
Description
The loose joint that socket seals fastening pipe belongs to pipe connection device.
Shen Qing pipe itself loose joint that just can couple together pipe in recent years without machining screw, though overcome the trouble of installing, but still have complex structure, especially the connection of nonmetallic pipe is not reached the shortcoming of sealing effect.
The purpose of this utility model is a kind of loose joint of design, when pipe itself not machining screw just can realize the connection of pipe way, especially can reach the effect of fit sealing to the connection of nonmetallic pipe.
The utility model is made up of connecting body, open washer, nut.Connecting body is a symmetrical structure, and being combined as a whole by cylindrical column sleeve 6 and interior cylindrical sleeve 7 forms.The cylindrical column sleeve has outside thread, so that and nut cooperation.The post height of interior cylindrical sleeve is longer than cylindrical column sleeve, the external diameter of interior cylindrical sleeve is littler than the internal diameter of cylindrical column sleeve, the inside radius of cylindrical column sleeve will equal or be slightly larger than the wall thickness that will be connected pipe with the difference of the outer radius of interior cylindrical sleeve, the external diameter of interior cylindrical sleeve is the internal diameter that will connect pipe, be processed with several groove in interior cylindrical sleeve than the outside that cylindrical column sleeve grows the position, help the fastening of non-metal tube and sealing, open washer 3 is placed on the outside of connection pipe and the inside of nut, and pipe is inserted between the inside and outside circle column sleeve.
The utility model can not reach when connecting nonmetallic pipe just can conveniently be realized being fastened and connected to the body machining screw, simple to operate, saves man-hour, and easy accessibility is without special tool.Also can reach above-mentioned effect as long as add an O-ring seal when metal tube is connected.The loose joint of adopting this structure to can be made into threeway, curved logical, reducing, four-way, be connected with valve.
Fig. 1 is an overall structure schematic representation of the present utility model.
Fig. 2 is the structural representation of connecting body 1.
Fig. 3 is the structural representation of open washer 3.
Fig. 4 is an overall structure schematic representation of the present utility model when connecting metal tube.
Fig. 5 is the structural representation of rubber washer 9.
Embodiment one: present embodiment is made up of connecting body 1, nut 2, open washer 3.Connecting body 1 is a bilateral symmetry formula structure, and the centre is a hexahedron 5, respectively is a cylindrical column sleeve 6 about hexahedron, and cylindrical column sleeve 6 has outside thread, so that and nut cooperation.Comprised an interior cylindrical sleeve 7 in the cylindrical column sleeve 6 again.The post height of interior cylindrical sleeve is longer than cylindrical column sleeve, the external diameter of interior cylindrical sleeve is littler than the internal diameter of cylindrical column sleeve, the inside radius of cylindrical column sleeve is the wall thickness that will be connected pipe with the difference of the outer radius of interior cylindrical sleeve, the external diameter of interior cylindrical sleeve is an internal diameter of wanting connecting tube, is processed with two road grooves 8 in interior cylindrical sleeve than the outside that cylindrical column sleeve grows the position.Respectively one on nut about 2.Pipe 4 is inserted between the inside and outside circle column sleeve.Open washer 3 also be about each one, packing ring 3 is enclosed within the inside of the top and nut 2 of nonmetallic pipe 4, reaches packing washer 3 gradually by the screwing of cylindrical column sleeve 6 of nut 2 and connecting body 1, and being tightly connected between fastening pipe 4 and the interior cylindrical sleeve 7.
Embodiment two: present embodiment and embodiment's one difference is to have increased a rubber washer 9, rubber washer 9 is placed on the outside of metal tube, below the open washer 3, utilize this loose joint still can reach to metal body itself not machining screw with regard to the salable effect that is fastenedly connected.
