Description

A kind of rotary swivel link

Technical field

The utility model relates to a kind of fixture of water tap, particularly a kind of rotary swivel link.

Background technique

Usually our position of its water outlet of water tap of using is changeless, can feel inconvenient when using so unavoidably, the water tap that a kind of water outlet can rotate freely has appearred for this reason now, this water tap mainly is that the link that leans against a kind of O of the being equipped with RunddichtringO that is adopted between outlet pipe and the main body is realized its rotation, this link is the tubular structure of single-piece normally, be with seal ring in its outside, the one end is linked to each other with tap main body, outlet pipe directly is enclosed within the outside of link, just be stuck in another groove of link after the outlet pipe outside screws in a screw again, outlet pipe vertically is fixed but still is rotatable like this, because the water shutoff effect of seal ring, the joint can not leak, but be to use the link of this structure still to have some defectives: because outlet pipe is often longer, so can produce bigger swing between outlet pipe inwall and link surface of contact when rotated, thereby cause rotation to have some setbacks, two O RunddichtringOs can produce radial pressure because of this swing simultaneously, be worn easily, influence its sealing, reduction of service life, the friction of screw and groove side more also influences the link life-span in addition.

Summary of the invention

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of swing that reduces outlet pipe, makes its smooth rotation, and helps prolonging the seal ring rotary swivel link in working life.

The technological scheme that its technical problem that solves the utility model adopts is:

A kind of rotary swivel link, it is characterized in that comprising the rotation core and be set on the outer core retainer plate of rotation core, wherein rotating core is hollow tubular structure, the one end is for connecting the joint one of main body, wear-resisting circle one is housed on the step surface of joint more than one, wear-resisting jump ring circle is housed in adjacent jump ring groove, on the shaft shoulder of the rotation core the other end wear-resisting circle two is housed, in the groove between wear-resisting circle one and wear-resisting circle two seal ring is installed, through hole one end of described rotation core has instrument jack one; Core retainer plate is a hollow tubular structure, the one end is for connecting the joint two of outlet pipe, the matching hole that its inwall has the wear-resistant trough that matches with wear-resisting circle one, the jump ring inside groove that matches with wear-resisting jump ring circle successively, matches with seal ring and wear-resisting circle two, inwall one end of described core retainer plate also has instrument jack two.

In the secondary seal groove of core retainer plate one end, the secondary seal circle is housed.

The beneficial effects of the utility model are: because this rotary swivel link is positioned at the both sides of seal ring on the rotation core two wear-resisting circles have been installed respectively also, so wear-resisting effect that has enclosed support and balance when rotating between rotation core and the core retainer plate, just can not produce bigger swing between its surface of contact, make its smooth rotation, even slight swing is arranged, at first Mo Sun meeting is wear-resisting circle, so seal ring has obtained sufficient protection; This link has also increased a core retainer plate, and the joint two on the core retainer plate can be realized being connected with the dismantled and assembled of outlet pipe, and is easy to use; Use wear-resisting jump ring circle instead between rotation core and the core retainer plate and fix the friction that can reduce the joint greatly, increase the service life; Can realize the secondary seal of link in addition after outside core retainer plate the secondary seal circle being installed again, sealing effect is better.

Embodiment

With reference to Fig. 1,2,3,4, a kind of rotary swivel link, comprise rotation core 1 and be set on the core retainer plate 2 that rotates outside the core 1, wherein rotate core 1 and be hollow tubular structure, the one end is for being with externally threaded joint 1, on the step surface 12 of joint more than one 11, wear-resisting circle 1 is housed, wear-resisting jump ring circle 4 is housed in adjacent jump ring groove 13, on the shaft shoulder 14 of rotation core 1 the other end wear-resisting circle 25 is housed, more than two wear-resisting circle surface smoothings, two grooves 15 are arranged between wear-resisting circle 1 and wear-resisting circle 25,15 ', be separately installed with seal ring 6 in it, 6 ', the rotation core 1 through hole 16 1 ends have be in hexagonal instrument jack 1, its feed-water end is provided with guide surface 18; Core retainer plate 2 is a hollow tubular structure, the one end is to be used for connecting the externally threaded joint 2 21 of being with of outlet pipe, its inwall have successively the wear-resistant trough 22 that matches with wear-resisting circle 1, the jump ring inside groove 23 that matches with wear-resisting jump ring circle 4, with seal ring 6,6 ' and the matching hole 24 that matches of wear-resisting circle 25, inwall one end of core retainer plate 2 is interior hexagonal instrument jack 2 25 in addition, in the secondary seal groove 26 of core retainer plate 2 one ends secondary seal circle 7 is housed.

With reference to Fig. 5,6, rotation is with on the core 1 between externally threaded joint 1 and the main body 9 and can be realized dismantled and assembled the connection during use, in wherein being hexagonal instrument jack 1 can ccontaining instrument conveniently to screw, be with on the core retainer plate 2 between externally threaded joint 2 21 and the outlet pipe 10 and also will realize dismantled and assembled the connection, in wherein being hexagonal instrument jack 2 25 can ccontaining instrument so that screw; Wear-resisting jump ring circle 4 is stuck in the jump ring groove 13 and the jump ring inside groove 23 on the core retainer plate 2 that rotates on the core 1 behind rotation core 1 and core retainer plate 2 fits, has so just limited the axial motion between rotation core 1 and the core retainer plate 2, and still can relatively rotate between them; Be installed in two seal ring 6 and 6 ' its external diameter and the core retainer plate 2 interior matching holes 24 of rotation on the core 1 and closely cooperate, played the water shutoff effect; And two wear-resisting circles 1 that are positioned at the seal ring both sides and wear-resisting circle 25 match with the core retainer plate inwall respectively, so two wear-resisting circles have just played the effect of support and balance when rotating between rotation core 1 and the core retainer plate 2, just can not produce bigger swing between its surface of contact, make its smooth rotation, even slight swing is arranged, at first Mo Sun meeting is wear-resisting circle, so two seal rings 6 and 6 ' have just obtained sufficient protection; Outside core retainer plate 2, install again in addition its external diameters of secondary seal circle 7 back with connection outlet pipe 10 inwall closely cooperate, so also can realize the secondary seal of this rotary swivel link, sealing effect is better.

Above-mentioned just the utility model preferred embodiment, it does not constitute restriction of the present utility model.The utility model can also have other constructional variant; the for example wear-resistant trough 22 that distributes successively at the core retainer plate inwall, matching hole 24 etc.; do not stipulate the form that it is concrete; as long as its structure can match with corresponding wear-resisting circle 1, seal ring 6 and wear-resisting circle 25, all belong to protection domain of the present utility model.
