Abstract
The utility model relates to a doubly sealed leak-proof connector, which is used for water taps without connection threads in water outlet and for the connection of a hard water pipe and a hose. The doubly sealed leak-proof connector is composed of a connector body with a passage in the middle, a pinch nut and an elastic sealed sleeve, wherein, the upper part of the connector body at least has three clamping flaps; perforated external threads are arranged from the combined part of the hose connector and the clamping flaps to the upper part of the clamping flaps; the middle part of the inner bottom of the elastic sealed sleeve is provided with a flange with an upturning edge. S-shaped structural form between the elastic sealed sleeve and the connector is in interference fit and dilates outwards the clamping flaps. The internal thread of the pinch nut and the external thread of the connector body form into a screw pair. The utility model has doubly sealed and leak-proof actions.
Description
The utility model belongs to a kind of pipe joint, is specifically related to the device that a kind of flexible pipe connects with firm element.
Traditional jointing in the prior art mostly is socket joint type greatly, is characterized in easy to use, but seals badly, and it is also unreliable to connect, and ducted pressure has increase slightly, just often by towards taking off.Chinese patent has been announced the patent application that application number is 91209923.2 " water pipe (water tap) water outlet connector assembly ", aspect sealability be connected reliable aspect and be enhanced than traditional jointing, but need when being to use turnbuckle is upwards revolved, again the water outlet of joint and water pipe (water tap) is pegged graft and exerts oneself to go up to push up, and then with turnbuckle to backspin, till clamping.Obviously, use is not too easily, must bimanualness can finish; Moreover " straight section " length of faucet outlet external diameter is limited, during grafting since on the obstruction of the turnbuckle that revolves, the grafting of water outlet and joint is difficult to put in place, thereby sealing must be subjected to bigger influence with the reliability that is connected.
The double-sealing Matheson and Dresser joint that the purpose of this utility model provides a kind of easy to use, good seal performance, firm and reliable connection, outer wall and its end face of effluent pipe mouth all had seal action.
The technical solution of the utility model is: the top that the lower end is provided with the joint body of hose coupling is provided with three lobes clamping limb at least, the centre of joint body is provided with passage, is shaped on the outside thread of perforation to the top that clamps limb from hose coupling and the connecting part that clamps limb.The middle part at the end is provided with the flange to upper overturning in the elastic seal cartridge, and the collar external diameter of flange is less than the internal diameter of corresponding pipeline outlet, will clamp limb and outwards strut for S type structural type is interference fit between elastic seal cartridge and the joint body.The internal thread of locking nut and the outside thread of joint body are formed screw pair.
During use, if earlier with locking nut to backspin, again the corresponding pipeline outlet is inserted in the elastic seal cartridge, and upwards pushes up to the end face of corresponding pipeline outlet and the flange outer wall cambered surface place in the elastic seal cartridge and match, and then locking nut rotated up get final product.
Positive effect of the present utility model is simple in structure, good seal performance, firm and reliable connection, can be under the pressure more than the 1MP proper functioning and do not have leakage, do not dash and take off.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the plan view of Fig. 1.
Below in conjunction with drawings and Examples the utility model is further described:
The top that the lower end is provided with the joint body 1 of hose coupling 5 is provided with pintongs clamping limb 4, and the centre of joint body 1 is provided with passage, from hose coupling 5 and the outside thread 7 of the connecting part that clamps limb 4 to the perforation of the top system that clamps limb 4.The middle part at the ends is provided with the flange 6 to upper overturning in the elastic seal cartridge made from rubber 3, is that S type structural type is interference fit and will clamps limb 4 and outwards strut between elastic seal cartridge 3 and the joint body 1.The internal thread 8 of locking nut 2 is formed screw pair with the outside thread of joint body 17.
