Abstract
Disclosed is a joining piece of a screw cap locking type pipe, used for fast jointing of pipe, wherein, one end of the pipe 1 is fixed on the inner wall of the pipe body 6; a seal ring 5, a gasket 4, a locking ring 8 and a locking screw cap 2 are arranged in turn on the two end surfaces of the pipe body 6 and the outer column surface of the pipe 1; the internal screw thread of the locking screw cap is engaged with the external screw thread of the pipe body to form a screw thread connection; a gap7is arranged on the circumference of the locking ring 3, a cone 10 which is positioned at one side of the locking ring 3 is provided with a plurality of evenly distributed flexible teeth 8, a cone 11 is positioned at one side of the gasket 4. The utility model, which has the advantages of simple structure, strong sealing ability and no leakage, does not need to process the screw thread at the two ends of the pipe and can be assembled and disassembled rapidly without any other assistant tool, and the joining piece is tight, the anti-pull ability is strong. The joining piece can be connected with various pipes, such as a straight pipe, a three-way pipe, a bend pipe and a pipe with variable diameter.
Description
Technical field: the utility model is the link that pipe connects usefulness fast.
Background technique: at present the pipe connection kind is a lot, but deficiencies of various degrees all.Link as the imperforation lock ring is very difficult in the dismounting of fastening back, and the pipe termination of making the link connection of pipe joint all needs machining screw, not only connect trouble, and sealing effect is also bad, occurs the seepage phenomenon easily.
Summary of the invention: the utility model is a kind of nut fastening-type pipe connection of development, it can be mounted and dismounted fast and easily, and can prevent seepage.The utility model is made up of fastening nut 2, lock ring 3, packing ring 4, seal ring 5, main pipe body 6.One end of pipe 1 is fixed on the inwall of main pipe body 6, is disposed with seal ring 5, packing ring 4, lock ring 3, fastening nut 2 on the external cylindrical surface of the both sides of main pipe body 6 end face and pipe 1; Outside thread engagement on internal thread on the fastening nut 2 and the main pipe body 6, formation is threaded.Have a breach 7 on the circumference of lock ring 3, lock ring 3 has the conical surface 10 in the face of on the side of main pipe body 6, evenly is provided with Elastic Teeth 8 on the conical surface 10, has the conical surface 11 on the relative side of packing ring 4 and the conical surface 10.Its working principle is: when screwing fastening nut 2, seal ring 5, packing ring 4, lock ring 3 be extruding forward successively, the conical surface 11 interaction under sheds 7 on the conical surface on the lock ring 3 10 and packing ring 4 tighten, Elastic Teeth 8 is shunk, and forces lock ring 3 with pipe 1 locking, because the opening on the lock ring 3 and the structural feature of Elastic Teeth 8, make the joint can discrepancy not take place because of the effect of interior pressure or external force, when unclamping fastening nut 2, opening 7 on the lock ring 3 and Elastic Teeth 8 distendings can be dismantled easily.The utility model is simple in structure, and sealing is strong, non-leakage, and the pipe termination does not need machining screw, do not need other assistant tool just can realize fast assembling-disassembling, and be connected firmly, resistance to tension is strong, and this link can be connected with the pipe of various ways such as straight-through, threeway, bend pipe, reducer pipe.
Description of drawings: Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the structural representation of lock ring 3 in the embodiment one, and Fig. 3 is the right elevation of Fig. 2, and Fig. 4 is the structural representation of lock ring 3 in the embodiment two, and Fig. 5 is the A-A sectional view of Fig. 4.
Embodiment one: present embodiment is made up of fastening nut 2, lock ring 3, packing ring 4, seal ring 5, main pipe body 6.One end of pipe 1 is fixed on the inwall of main pipe body 6, is disposed with seal ring 5, packing ring 4, lock ring 3, fastening nut 2 on the external cylindrical surface of the both sides of body main body 6 end face and pipe 1; Outside thread engagement on internal thread on the fastening nut 2 and the main pipe body 6, formation is threaded.Have a breach 7 on the circumference of lock ring 3, lock ring 3 has the conical surface 10 in the face of on the side of main pipe body 6, has Elastic Teeth 8 on the conical surface 10 of lock ring 3.Has the conical surface 11 on the relative side of packing ring 4 and the conical surface 10.
Embodiment two: what present embodiment and embodiment one were different is to be embedded with Elastic Teeth 8 on the conical surface 10 of lock ring 3.Other composition is identical with embodiment one with annexation.
Embodiment three: present embodiment and embodiment one are different be packing ring 4 with seal ring 5 relative sides on have concave arc 9.Other composition is identical with embodiment one with annexation.
