Description

Make things convenient for rapid pipe joint

The utility model relates to a kind of quick-acting joint of rakish connecting joint, particularly a kind of low pressure, is applicable to that automatic washing machine supplies water or similar water supply supply air line.

Existing washing machine inflow is that the washing machine inflow pipe collar is pricked on water tap, this Placement, not only connecting hoop pricks inconvenient, also can bring the trouble of leaking, for this reason, the Chinese patent name is called quick loading and unloading washing machine inflow device, the patent No. is ZL 91201645.0, solution has been proposed, it is made up of the second portion that the first portion that links to each other with water tap links to each other with intake pipe of washing machine, the last Coupling of first portion is used for this device is screwed at water tap, its sealing gasket is in order to protect the sealing of first portion and water tap, external member has a tubular configured joint to be used for cooperating with second portion under it, second portion is established a upper coarse and lower fine cylinder and an outer sleeve, the thin part in bottom links to each other with intake pipe of washing machine, four holes are evenly established along periphery in cylinder top, the outside is arranged against the overcoat bead in the hole, also has seal ring in the cylinder, during use, only need tubular configured joint to insert cylinder top and reach quick loading and unloading purpose, but still there is following point in this structure: utilize water tap, radially push up affixed head with screw, not only mounting or dismounting are extremely inconvenient, owing to axially do not tighten up power, even seal washer is arranged, still easily produce water leakage phenomenon, its outer little spherical structure must pull down earlier when mounted up to be lifted and can fix, and also makes troubles to use, in order to solve loading and unloading inconvenience, the washing machine special-purpose tap that supplies water is set on pipeline, but this measure again can increase expense expenditure, product needs through adopting more metal parts in order to install, also can increase the product cost, and Mechanical Builds shows attractive in appearance inadequately.

The purpose of this utility model is that a kind of improved rapid pipe joint that makes things convenient for will be provided, its loading and unloading and easy to use, and good airproof performance, and moulding is lightly attractive in appearance.

Model utility is achieved in that establishes the valve of often opening in the joint coupled condition in connection block, establishing on the connection block in the joint coupled condition can the blocking joint and the pedestal of SEALING FITTING internal channel; Establish fittings body on the joint, fittings body upper end is established joint and is unloaded cover, and fittings body and joint unload inner room and establish outer spring, and the inner chamber that fittings body and joint unload cover is established pipe and connect, and pipe connects the lower end and the fittings body lower end is fixed, and pipe connects to hold establishes several steel balls, and pipe connects inner chamber and establishes resilient sleeve.

The advantage of the utility model said structure is: if with joint gently pushing tow go into connection block, just intake pipe of washing machine and running water pipe can be connected, it is extremely convenient to pack into, and the sealing engagement face that pushed by spring force of sealing and being guaranteed really; When dismantling, if with joint unload cover gently one by, joint rapidly with the connection block disengagement, also extremely convenient; Connection block is connected on the tap water pipe line with thread seal, and after joint unloaded, the valve of connection block cut out automatically, and not only good airproof performance also keeps the complete and attractive in appearance of whole pipeline; And whole quick coupling structure compactness, handsome in appearance.
