Abstract
The utility model discloses a connection piece. The connection piece comprises two screwed joints and a flexible connecting piece for connecting the two screwed joints. Both ends of the flexible connecting piece are provided with grooves for holding the screwed joints, and an outer side of each of the grooves projects into an annular projection. Each screwed joint is provided with a protection part at the outer side near the flexible connecting piece, and a groove cooperating with one of the annular projections is formed between the protection part and the screwed joint, wherein the annular projection is embedded into the groove which effectively fastens the flexible connecting piece with the screw joint. The flexible connecting piece and the screw joints do not separate or fall off during usage.
Description
Technical field
The utility model relates to a kind of link.
Background technique
Link is a kind of widely used being fixedly connected with, or dismountable being fixedly connected with, have simple in structure, connect reliable, the advantages such as mounting or dismounting are convenient, in actual production, there are two threaded joints, as on automobile for the link between vehicle motor and the inlet pipe connection on it, and by rigid pipe, connect between this two threaded joints, when this kind of link is used for the connection between accessory, due to rigid pipe bending, reverse, therefore require two positions between accessory to have and the precision of link itself very high, if any deviation, can not complete two assemblings between accessory, this link is inconvenient in actual applications, flexibility ratio is low, in prior art, this being rigidly connected transformed, if any China Patent No., be 201120139494.3 to disclose a kind of link model utility, comprise two screwed joints (1), it is characterized in that: two described screwed joints connect by flexible member.Adopt said structure, owing to adopting flexible member to connect between two screwed joints, at this link, be used for connection and the assembly process between two parts, just can realize the arbitrarily angled cooperation of upper and lower regioselective, more flexible while making to assemble, convenient, this link left-right and front-back flexibility ratio can reach 15 ~ 20mm, up and down the angle of location can be in 360 ° arbitrary disposition.This technology also exists following not enough in application, although flexible connecting member can be realized certain cooperation of upper and lower regioselective, flexible connecting member and inipple are fixing bad, and both are separated, landing easily.
Model utility content
In order to overcome the defect of above-mentioned prior art, the utility model provides a kind of link, and this link can effectively prevent that flexible connecting member and inipple are fixing bad, during use both can be not separated, come off, thereby reach the effect being fastenedly connected.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of link, comprise two inipples with for being connected the flexible connecting member of two inipples, described flexible connecting member two ends are equipped with the groove of accommodating inipple, it is characterized in that: the groove outside of described flexible connecting member raises into an annular convex; Two inipples are provided with protection portion near the outside of flexible connecting member one end, form the groove matching with described annular convex between protection portion and inipple, and described annular convex embeds in described groove.
The outside of described protection portion is provided with screw, and screw is fastening by inipple and flexible connecting member through screw.
Described screw is sunk screw.
The utlity model has following advantage:
1, in the utility model, the groove of flexible connecting member outside raises into an annular convex; Two inipples are provided with protection portion near the outside of flexible connecting member one end; between protection portion and inipple, form the groove matching with described annular convex; described annular convex embeds in described groove; the annular convex of flexible connecting member embeds between protection portion and inipple and forms in groove; groove is effectively fixed flexible connecting member and inipple; in use, flexible connecting member and inipple can be not separated, come off for this link.
2, in the utility model, the outside of protection portion is provided with screw, and screw is fastening by inipple and flexible connecting member through screw, by reinforcing by screw by the fixing flexible connecting member of groove and inipple, makes fastening better effects if again.
3, in the utility model, screw is used sunk screw, and screw can not protrude the outside of protection portion, and work is convenient, better effects if.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present utility model;
Mark 1, inipple in figure, 2, flexible connecting member, 3, annular convex, 4, protection portion, 5 screws.
Embodiment
As shown in Figure 1, a kind of link, comprise two inipples 1 with for being connected the flexible connecting member 2 of two inipples 1, described flexible connecting member 2 two ends are equipped with the groove of accommodating inipple 1, the groove of described flexible connecting member outside raises into an annular convex 3; Two inipples 1 are provided with protection portion 4 near the outside of flexible connecting member one end, form the groove matching with described annular convex 3 between protection portion 4 and inipple 1, in the described groove of described annular convex 3 embedding.In the party's peace, the annular convex 3 of flexible connecting member 2 embeds between protection portion 4 and inipple 1 and forms in groove; groove is effectively fixed flexible connecting member 2 and inipple 1; therefore this link in use, flexible connecting member 2 and inipple 1 both easily separated, come off.
In order to make flexible connecting member 2 and the fastening better effects if of inipple 1, in the outside of described protection portion 4, be provided with screw, screw 5 is fastening by inipple 1 and flexible connecting member 2 through screw.
For making screw can not protrude the outside of protection portion, work is convenient, better effects if, and described screw 5 is sunk screw.
Claims (1)
