Abstract
The utility model discloses a crack control fastening components, it is used for connecting at least two and treats the connecting piece, it includes the screw, set up the screw hole on the connecting piece the farthest away of the spiral shell head apart from the screw, the screw hole has including the screw section of coaxial setting and platform section, the platform section is held to the bottom of platform section with the crossing face place of screw thread section, the diameter of screw thread section is less than the diameter of platform section, the screw includes the spiral shell head, establish the portion with screw thread section assorted screw thread portion and with platform section assorted load, screw thread portion establishes a coaxial coupling with the load, the screw thread section degree of depth is greater than screw thread minister degree, the platform section degree of depth is less than or equal to the length that the portion was established to the load. The utility model discloses utilize the load portion of establishing to support tightly in the bottom of platform section, prevent that screw thread portion from too going deep into the screw thread section and leading to treating that the connecting piece rises splits.
Description
Technical field
This utility model relates to auto-parts field, particularly to a kind of anticracking fastening assembly.
Background technology
The fastening assembly that existing bolt-hole coordinates, when screw screws in part to be connected, if conference of exerting oneself causes that part to be connected is split up, causes unnecessary loss.
Summary of the invention
The purpose of this utility model is to provide a kind of anticracking fastening assembly.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of anticracking fastening assembly, it is used for connecting at least two part to be connected, it includes screw, it is opened in the screwed hole on the connector that the screw head from described screw is farthest, described screwed hole has the thread segment and platform section that include being coaxially disposed, the intersection place end of described platform section and described thread segment is the bottom of platform section, the diameter of described thread segment is less than the diameter of platform section, described screw includes screw head, the threaded portion matched with described thread segment and the load matched with platform section set portion, it is coaxially connected that described threaded portion and described load set portion, the described thread segment degree of depth is more than flighted length, the described platform section degree of depth sets the length in portion less than or equal to described load.
Optimizing, the diameter of the screw head of described screw sets the diameter in portion more than described load.
Owing to technique scheme is used, this utility model compared with prior art has the advantage that this utility model utilizes the load portion of setting to be pushed against the bottom of platform section, it is prevented that threaded portion is excessively goed deep into thread segment and caused that part to be connected is split up.
