Abstract

The utility model universal joint, comprise plastic casing, large silica gel ring, little silica gel ring, larynx hoop, step is done bottom little silica gel ring, groove is done bottom large silica gel ring, limited step is done at plastic casing top, by plastic casing and large silica gel ring and mutually spacing between large silica gel ring and little silica gel ring, reaches the slip that each accessory causes because of hydraulic pressure effect, locking intensity is high, long service life.

Description

Novel universal joint

Technical field

The utility model provides a kind of water purifier and is installed on a kind of locking method without threaded water faucet.

Background technique

Universal joint is commonly used in current water purifier field two kinds: the first silica gel universal joint, comprise plastic casing 1, silica gel ring 2, silica gel ring 3, this four part of larynx hoop 4 forms, silica gel ring 3 is installed to inside silica gel ring 2, then installs in plastic casing together, then be installed to without locking throat hoop on threaded water faucet 4, when hydraulic pressure is higher, silica gel ring 3 and silica gel ring 2, silica gel ring 2 slides because frictional force is not enough outward with plastic casing inwall, causes leaking even using product to fall down; The second rubber universal joint, comprise band copper mold insert rubber ring 5 and rubber ring 6, larynx hoop 4 forms, when hydraulic pressure is higher, bulging is there will be bottom rubber ring 5, occur rubber ring 5 and the division of copper mold insert time serious and leak, simultaneously also there is friction and slides outward not in rubber ring 6 and rubber ring 5, and the even use product that causes leaking falls down.

Model utility content

The purpose of this utility model is locking intensity and the working life of improving universal joint.

The structure of model utility is as follows:

The utility model universal joint structure, comprise plastic casing, large silica gel ring, little silica gel ring, larynx hoop four part composition, do step bottom little silica gel ring, do groove bottom large silica gel ring, limited step is done at plastic casing top.The beneficial effects of the utility model are: large silica gel ring limits little silica gel ring and slides, and plastic casing restriction large silica gel ring slides, and prevents the slip because of hydraulic pressure effect generation between each accessory, improves locking intensity and the working life of universal joint.
