Detailed Description
In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; may be mechanically coupled, may be electrically coupled or may be in communication with each other; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
In the present application, unless expressly stated or limited otherwise, the first feature may be directly on or directly under the second feature or indirectly via intermediate members. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.
Referring to fig. 1-8, the utility model provides a heterotypic bolt and nut subassembly for car, including bolt 1 and the nut 2 of being connected with 1 screw-thread fit of bolt, wherein:
the bolt 1 comprises a nut 11 and a screw 12 connected with the nut 11, wherein the screw 12 is provided with a protruding part 3; the projection 3 of the screw 12 is in the shape of a truncated cone, the outer diameter of the truncated cone gradually increases from one end to the other end, the large-diameter end of the truncated cone is close to the nut 11, the outer circumference of the truncated cone is provided with external threads, and the threaded projection 3 can be connected with the mounting hole on the first spare part 6 through the external threads.
