Abstract
The utility model discloses an inserted tube type connector comprising a tubular connector body. Spring sheets are evenly and peripherally arranged at two ends of an inner hole of the tubular connector body. The parts, outside the spring sheets, of the inner hole of the tubular connector body form stepped holes. Z-shaped ferrules are fitted into the stepped holes. Tube adapters are fitted into the ferrules. The outer periphery of each tube adapter is provided with a cylindrical step. The outer periphery of one end of each tube adapter is tapered. The motion range of the tube adapters on the connector body is limited, the tapered structure ejects off the spring sheets, and accordingly, insert tubes to be connected can be inserted into the connector and clamped by resetting force of the spring sheets; the tube adapters are used to prevent the excessive resetting force of the spring sheets from damaging the insert tubes, so that the service life of the connector is prolonged and the inserted tube type connector is highly convenient to use.
Description
Technical field
The utility model relates to a kind of tracheae pipeline connecting part, specifically a kind of tube-inserted type jointing.
Background technique
The gas circuit of using at gaspipe line, big-load trailer at present all needs to use joint to connect in connecting.Existing jointing mostly utilizes the rubber property of tracheae, by interference fit, connect and then use buckle fastening, this kind of Placement be because rubber expands with heat and contract with cold and the natural characteristic such as aging, often working life not long, cause the technological deficiencies such as tracheae gas leakage.Certainly also there are some to adopt spring sheet technology clamp by spring sheet the joint that the mode of insertion tracheae connects tracheae, but this joint is extracted difficulty after existing and inserting, and lower working life owing to lacking good seal means in using process, easily gas leakage.
Chinese utility model patent patent No. ZL201120409609.6 discloses a kind of gas-tpe fitting, comprise inflator joint and tracheae female joint, tracheae female joint is provided with tracheae female joint passage, in tracheae female joint passage, be provided with one-way valve, one-way valve comprises valve seat, spool and stage clip, install in tracheae female joint passage valve base sealing, on valve seat, offer the valve opening of conducting tracheae female joint passage, spool is inserted in valve opening, on spool, compared with the end of inflator joint far-end, convex with seal ring, the diameter of seal ring is greater than the diameter of valve opening, compression spring sleeve be located on spool with respect to seal ring place end compared with far-end, one end of stage clip and valve seat are inconsistent fixing, the other end and spool are connected and fixed.This kind of its structure relative complex of joint, does not propose relative cost technological scheme lower, easy to use.
Summary of the invention
The utility model provides the tube-inserted type jointing that a kind of simple in structure, easy to use, life-span is long, prevent gas leakage.
A kind of tube-inserted type jointing, comprise tubular configured joint body, the even circumferential at joint body endoporus two ends is distributed with spring sheet, the endoporus of the joint body in described spring sheet outside is step hole, step hole inner side is combined with zigzag cutting ferrule, the cutting ferrule inner side intubate seat that is connected, intubate seat periphery is provided with cylindric step; Described intubate seat end periphery is coniform.This kind is middle hole, bridge connected unit rank and intubate seat by zigzag cutting ferrule, limited the range of movement of intubate seat at joint body, cone-shaped structure by intubate seat end periphery backs down spring sheet and makes to need the Inserting Tube connecting to enter easily in joint, there is the ability of freeing in and out, as long as then loose one's grip, spring sheet reposition force can clamp Inserting Tube, because intubate seat props up spring sheet at the limited cone-shaped structure of range of movement of joint body, can prevent the working life that the excessive damage for Inserting Tube of spring sheet reposition force has improved joint, there is higher property easy to use.
The inner hole wall of the joint body of described spring sheet inner side is provided with annular shrinkage pool, in annular shrinkage pool, seal ring is installed; As being provided with pore in the preferred described seal ring of structure, by air hole structure, increase the elasticity of seal ring, prevent the gas leakage problem causing because seal ring is aging.
Described joint body axial centre is provided with inwardly protruded flange, and this kind of flange has polarization, and its flange sidewall contact props up the Inserting Tube that needs connection, has effectively realized the accurate location for Inserting Tube.
The utility model is the range of movement at joint body by restriction intubate seat, by cone-shaped structure, backing down spring sheet makes to need the Inserting Tube connecting to enter in joint, spring sheet reposition force clamping Inserting Tube, and prevent by intubate seat the working life that the excessive damage for Inserting Tube of spring sheet reposition force has improved joint, there is higher property easy to use.
Accompanying drawing explanation
Be illustrated in figure 1 the utility model tube-inserted type jointing sectional structure schematic diagram;
Be illustrated in figure 2 the utility model tube-inserted type jointing perspective view.
Embodiment
A kind of tube-inserted type jointing as shown in Figure 1, 2, comprise tubular configured joint body 5, the even circumferential at joint body 5 endoporus two ends is distributed with spring sheet 3, the endoporus of the joint body 5 in spring sheet 3 outsides is step hole, step hole inner side is combined with zigzag cutting ferrule 2, the cutting ferrule 2 inner sides intubate seat 1 that is connected, intubate seat 1 periphery is provided with cylindric step; Intubate seat 1 end periphery is coniform, has the ability of the spring sheet 3 that is connected.In order to improve stationkeeping ability joint body 5 axial centre of Inserting Tube, be provided with inwardly protruded flange 7.
Inner hole wall as the joint body 5 of the preferred spring sheet of structure 3 inner sides is provided with annular shrinkage pool, and seal ring 4 is installed in annular shrinkage pool, is provided with pore 6 in sealed picture 4.
