Abstract
The utility model relates to a fastener field especially relates to a threaded connection hole, including the connecting hole main part, the connecting hole inner wall is equipped with the internal thread, connecting hole inner wall symmetry is equipped with a plurality of recesses, the degree of depth of recess is no longer than the internal thread degree of depth, be equipped with the bead on the internal thread of recess both sides. The utility model discloses beneficial effect lies in, simple structure, and the technique is reasonable, the bead forms when passing through drift suppression recess, it is very convenient to make, in the threaded connection who does not influence screw and threaded connection hole, makes the internal thread and the face of being connected of external screw thread to be the mat surface through the bead to increase the friction between internal thread and the external screw thread, makeed threaded connection hole more firm with the threaded connection of screw.
Description
Technical field
This utility model relates to fastener areas, particularly relates to a kind of threaded connection hole.
Background technology
Threaded is a kind of common connected mode, and this connected mode facilitates the installation and removal between all parts. During connection, it is common that be attached by screw and suitable screwed hole, owing to the external screw thread of screw is suitable with the size of the female thread of screwed hole, during connection, external screw thread is mutually chimeric with female thread. So at equipment long-play, being under the environment of vibrations, it is possible that loosen the phenomenon even come off between screw and screwed hole.
Utility model content
This utility model is in order to solve defect and the deficiency existed in above-mentioned prior art, it is provided that a kind of threaded connection hole, is connected more firm with screw thread.
The technical solution of the utility model: a kind of threaded connection hole, including connecting hole main body, described connecting hole inwall is provided with female thread, and described connecting hole inwall is arranged with some grooves, the degree of depth of described groove is less than depth of internal thread, and the female thread of described groove both sides is provided with fin.
Formed when fin described in this utility model is by drift press flute, make very convenient, so that female thread and externally threaded joint face are matsurface, thus the friction added between female thread and external screw thread so that threaded connection hole is more firm with threadeding of screw.
As preferably, the length of described fin is 0.5mm to 1mm.
As preferably, the width of described groove is 1mm to 1.5mm.
This utility model has the beneficial effects that, simple in construction, technology is reasonable, formed when described fin is by drift press flute, make very convenient, while not affecting the threadeding of screw and threaded connection hole, make female thread and externally threaded joint face be matsurface by fin, thus the friction added between female thread and external screw thread so that threaded connection hole is more firm with threadeding of screw.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail, but is not the restriction to this utility model protection domain.
Embodiment 1
A kind of threaded connection hole, as depicted in figs. 1 and 2, including connecting hole main body 2, described connecting hole inwall is provided with female thread 1, described connecting hole inwall is arranged with some grooves 3, and the degree of depth of described groove 3 is less than female thread 1 degree of depth, and the female thread of described groove 3 both sides is provided with fin 4.
Wherein, formed when described fin 4 is by drift press flute 3, make very convenient, so that female thread 1 and externally threaded joint face are matsurface, thus the friction added between female thread 1 and external screw thread so that threaded connection hole is more firm with threadeding of screw.
Embodiment 2
The length of described fin 4 is 0.5mm to 1mm, and the width of described groove 3 is 1mm to 1.5mm.
Wherein, other structures of embodiment 2 are identical with the structure in embodiment 1, do not carry out concrete elaboration herein.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the premise without departing from principle described in the utility model; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
Claims (3)
