Abstract
The utility model relates to a joint structure of a winding pipe, and aims to solve the problems that the connection between conventional winding pipes is complicated, the installation is inconvenient, and the service life is short. The joint structure comprises a joint pipe, wherein sealing rings are sleeved on pipe walls at two ends of the joint pipe. The joint structure of the winding pipe is extreme, good in sealing performance, and long in service life, is convenient to install, and is not influenced by the environment.
Description
Technical field
The utility model relates to a kind of pipe coupling, a kind of specifically entwining tube interpolation type joint structure.
Background technique
The entwining tube of hollow with its lightweight, anti-corrosion, anti-aging, can utilize again and plurality of advantages such as environmental protection, substituted the ideal material that traditional concrete pipe, cast iron tube are just becoming the world, domestic city planting ductwork gradually.All there is application in fields such as of many uses, municipal, civilian, metallurgical, the chemical industry of entwining tube, agricultural etc.Guaranteed performance connects the key point that sealing is again entwining tube using effect and life-span reliably, but its joint problem then can not be well solved always.At present; Realize that the structure that connects between the entwining tube is mainly following several kinds: 1, adopt the butt-end of shrink belt with two entwining tube, heating makes it to shrink and reaches sealing effect to contraction bands then; This method is affected by environment big, and humidity more then sealing effect is poor; 2, utilize the molten technology of electric heating through pipe joint with the end of two entwining tube with it hot melt connect, need to use welding machine, Electric thermal smelting belt, fastening piece etc. in the operating process, complicated operation, environment and personnel hand-manipulated are required height.3. adopt a kind of joint of horn mouth formula to dock; With an end and an entwining tube welding of this joint, the other end is enclosed within on the outer wall of another winding, because the entwining tube external diameter of model varying strength of the same race is different; Even this just makes to same model entwining tube; Also will prepare the joint of multiple size, versatility is bad, and the cost of disposable input is very high.
Summary of the invention
The purpose of the utility model is in order to solve the problems of the technologies described above, and a kind of simple in structure, easy for installation, entwining tube joint structure that versatility is good is provided.
Technological scheme comprises adaptor tube, is with seal ring on the two ends tube wall of said adaptor tube.
The stage casing tube wall of said adaptor tube is provided with the limited ring to outer process.
Said adaptor tube is a hollow tubular, and its two ends can just in time be inserted in the corresponding entwining tube, and seal ring then can play the connection seal action, and it is spacing that the limited ring of center is used to the degree of depth that entwining tube is inserted in.Because the internal diameter of the entwining tube of model of the same race, different rings rigidity specification is unified in actual the use, therefore also can unify with the size of the entwining tube joint of entwining tube internal diameter coupling, versatility is good, is convenient to installation.During installation, directly the connection that can realize two entwining tube in the corresponding entwining tube is inserted at the two ends of adaptor tube.The utility model structure is very simple, easy for installation, good airproof performance, not affected by environment, long service life.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model scheme of installation.
Wherein, 1-pipe joint, 2-seal ring, 3-limited ring, 4-entwining tube, 5-entwining tube.
Embodiment
Below in conjunction with accompanying drawing the utility model is further explained:
With reference to Fig. 1, adaptor tube 1 is a hollow tubular, is with seal ring 2 on its two ends tube wall.The stage casing tube wall of said adaptor tube 1 is provided with the limited ring 3 to outer process.
During installation, the two ends of pipe joint 1 are inserted respectively in entwining tube 4 and the entwining tube 5, till the end of two pipes was withstood limited ring 3 respectively, this moment, seal ring 2 can play good seal action.
Claims (2)
1. an entwining tube joint structure is characterized in that, comprises adaptor tube, is with seal ring on the two ends tube wall of said adaptor tube.
2. entwining tube joint structure as claimed in claim 1 is characterized in that, the stage casing tube wall of said adaptor tube is provided with the limited ring to outer process.
