Abstract
The utility model discloses a self-positioning structure for threaded connection of plastics with metal. The self-positioning structure for threaded connection of the plastics with the metal is high in precision, strength and reliability, comprises a plastic part, a connector and a bolt, and is characterized in that a tapered guide opening is arranged on the upper surface of the plastic part, a hole with the hole size smaller than the outer diameter of a thread of the bolt is connected below the guide opening, the plastic part is fixedly connected on the connector, and a thread groove on the connector is concentric to the hole. The interference magnitude of the hole size of the hole and the bolt is one half of the thread height. The self-positioning structure is mainly used as a fan bolt connection structure.
Description
Technical field
The utility model relates to the self positioning structure that is threaded, and relates in particular to a kind of plastics and the metal threaded self positioning structure that is connected.
Background technique
The hole that the bolt in working of plastics of the prior art hole is connected to working of plastics is greater than the bolt diameter and is connected fastening with other accessory, there are many defectives in this bolton Placement, working of plastics aperture degrees of freedom is large, and size can't screw in bolt again, may cause connecting the precision disappearance.Plastics are low yielding with respect to its hardness of bolt in addition, and freely may occur greatly being out of shape plastic breakage causes Joint failure because of it.
Summary of the invention
The utility model discloses a kind of plastics and the metal threaded self positioning structure that is connected, in order to solve the deficiencies in the prior art.
For addressing the above problem, technical solution of the present utility model is:
A kind of plastics and the metal threaded self positioning structure that is connected, comprise working of plastics, link, bolt, it is characterized in that: described working of plastics upper surface is provided with the taper targeting port, be connected with the aperture under the targeting port less than the hole of bolt thread external diameter, working of plastics is fixed on the link, and the thread groove on the link is concentric with the hole.
The aperture in described described hole and bolt magnitude of interference be tooth high 1/2.
The beneficial effects of the utility model are: by the setting of above-mentioned working of plastics, can effectively avoid may causing connecting precision disappearance because plastics endoporus degrees of freedom is large, and working of plastics and bolt gapless, thus greatly improve precision, intensity, the reliability of working of plastics.
Description of drawings
Fig. 1 is the structural representation that is not spirally connected of the present utility model;
Fig. 2 is the structural representation of the utility model when being spirally connected;
Fig. 3 is that the utility model connects the structural representation after finishing;
Among the figure: 1-working of plastics, 2-bolt, 3-link, 4-targeting port, 5-hole.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Referring to accompanying drawing, the utility model comprises working of plastics 1, link 3, bolt 2, it is characterized in that: described working of plastics 1 upper surface is provided with taper targeting port 4, targeting port is connected with the aperture for 4 times less than the hole 5 of bolt 2 major diameter of threads, working of plastics is fixed on the link 3, and the thread groove on the link 3 is concentric with hole 5.
The aperture in described described hole 5 and bolt magnitude of interference be tooth high 1/2.
Endoporus upper end at working of plastics 1 when connecting is provided with taper targeting port 4, and the hole 5 less than major diameter of thread is arranged below the targeting port, and bolt 2 penetrates targeting port 4, draws to screw in the working of plastics hole 5, and is fastening to link 3.
Take above-mentioned improvement structure, effectively prevent tilt bolt, connect precision and reliability thereby greatly improve.
Above-mentioned embodiment is preferred embodiment of the present utility model; can not limit the utility model; other any change that does not deviate from the technical solution of the utility model and make or other equivalent substitute mode are included within the protection domain of the present utility model.
