Abstract
The locking metal insert of gear-like be the utility model is related to solve the technical problem of the junction of plastic parts in the prior art and metal insert easy relative motion in stress.The locking metal insert of gear-like of the present utility model is when in use, plastic parts is formed in the periphery of metal insert by way of injection, and a part of plastic cement is formed in neck and can play a part of preventing plastic parts from rotating on inserts body peripheral face during this.And width difference of the neck in the longitudinal direction at different cross section is even more that can play a part of preventing plastic parts opposing metallic inserts from sliding back and forth.And neck is formed on the annulus of protrusion, the annulus wall thickness of protrusion inserts body is even more the intensity for enhancing metal insert, can further prevent plastic parts opposing metallic inserts from rotating in the circumferential.
Description
Technical field
It the utility model is related to the locking metal insert of gear-like.
Background technology
Plastic cement is widely used in feedwater piping with the compound conduit coupling of metal tube, wherein, plastic cement passes through injection
Mode be enclosed in the outside of metal tube, the metal tube that middle part has the transfusing chamber passed through for fluid is embedded at plastic parts
It is interior, while the attachment structure for connecting pipe is provided with metal insert.But the connection of plastic cement and metalwork in the prior art
Be in by circumference active force when easily relatively rotate, this can influence conduit coupling leakage performance and with pipeline
Switching performance.
Utility model content
The purpose of this utility model is to provide a kind of locking metal insert of gear-like to solve plastic parts in the prior art
With the technical problem of junction easy relative motion in stress of metal insert.
To achieve the above object, the locking metal insert of gear-like of the present utility model uses following technical scheme：
The locking metal insert of gear-like, includes the inserts body of cannula-like, and inserts body has what is extended along the longitudinal direction
Axis, the outer peripheral face of inserts body are provided with annulus with protruding above, and annulus is coaxially disposed with inserts body, is spaced on the annulus
Offer multiple be caught in for plastic parts to prevent neck that plastic parts rotates on the outer peripheral face of inserts body, in the longitudinal direction
The width of neck is different at different cross section.
Annulus described in multi-turn is arranged at intervals with the outer peripheral face of inserts body along the longitudinal direction, the card opened up on every ring band
Groove corresponds in the longitudinal direction.
Also it is arranged at intervals with the fin that multiple tracks extends along the longitudinal direction on the outer peripheral face of the inserts body, fin staggers institute
State neck setting.
The anti-rotating hole being caught in for plastic parts in it is additionally provided with the outer peripheral face of the inserts body.
The anti-rotating hole is arranged on annulus and/or on fin and/or on neck.
The anti-rotating hole is the through hole of insertion inserts body wall thickness.
The beneficial effects of the utility model are as follows：The locking metal insert of gear-like of the present utility model when in use, plastic cement
Part is formed in the periphery of metal insert by way of injection, and a part of plastic cement is formed in neck and can risen during this
To the effect for preventing that plastic parts from rotating on inserts body peripheral face.And the width at different cross section is not in the longitudinal direction for neck
Same is even more that can play a part of preventing plastic parts opposing metallic inserts from sliding back and forth.And neck is formed on the annulus of protrusion,
The annulus wall thickness of protrusion inserts body is even more the intensity for enhancing metal insert, can further prevent that plastic parts opposing metallic is embedding
Part rotates in the circumferential.
Brief description of the drawings
Fig. 1 is the front section view of the locking metal insert of gear-like of the present utility model；
Fig. 2 is the side view of the locking metal insert of Fig. 1 middle gear shapes.
Embodiment
The structure of the locking metal insert of gear-like of the present utility model as depicted in figs. 1 and 2, includes the inserts sheet of cannula-like
Body 1, the middle part of inserts body 1 form the transfusing chamber 2 passed through for fluid, are spaced along the longitudinal direction on the outer peripheral face of inserts body 1
Three ring bands 3 are offered, offers and is caught in for plastic parts to prevent plastic parts in the periphery of inserts body 1 on every ring band 3
The neck 31 rotated on face, the neck 31 on multi-turn annulus 3 are mutually corresponding in the longitudinal direction.
The cell wall 32 of neck 31 is used for block plastic parts circumferentially rotating along the outer peripheral face of inserts body 1.Annulus 3 and inserts sheet
The coaxial line of body 1, the width of neck 31 is different at different cross section in the longitudinal direction, so plastic parts can be prevented with respect to inserts body
1 slides back and forth.
In order to further prevent plastic parts from being rotated relative to inserts body 1, it is additionally provided with the outer peripheral face of inserts body 1
The fin that multiple tracks extends along the longitudinal direction, the fin neck 31 that staggers are set, and multiple tracks fin is along the circumferential uniform of inserts body 1.
The anti-rotating hole 4 of insertion inserts body wall thickness is additionally provided with annulus 3, plastic parts injection molded is in metal insert outer peripheral face, portion
Plastic material is divided to flow into the anti-rotating hole 4 and further rotation stop.Anti-rotating hole 4 can be arranged on neck 31, can also
It is arranged on fin, is arranged on annulus while neck can also be staggered.
Certainly, in other embodiments, anti-rotating hole can also be set with staggering annulus on the outer peripheral face of inserts body；When
So, the anti-rotating hole can also be the blind hole in only outer end connection inserts body peripheral face.
The locking metal insert of gear-like of the present utility model when in use, is surrounded by way of injection outside metal insert
Shape plastic parts, plastic parts together form for connecting pipe to transmit the conduit coupling of fluid with metal insert.In plastic cement
In the forming process of part, it can be filled in the hole, slot structure on inserts body peripheral face by plastic parts material, so this practicality
The locking metal insert anti-rotation effect of new gear-like is good.
