Abstract
The utility model discloses an automobile special bolt with a straight grain structure, relating to an improved technology of a bolt structure. The automobile special bolt comprises a bolt head (1) and a threaded rod (2), wherein a cylinder (3) is connected between the bolt head (1) and the threaded rod (2); the outer surface of the cylinder (3) is provided with longitudinal ribs (4) along a circumferential direction; and the section of each rib (4) is in a shape of a closed angle. The automobile special bolt solves the problem that potential safety hazard is caused because the conventional automobile special bolt is easy to loosen and break when used. The ribs are formed on the surface of the cylinder between the threaded rod and the bolt head and have an anti-skidding effect, so that the loosening of the bolt caused by bumping is prevented when an automobile is acted; and additionally, the longitudinal ribs have a strengthening effect, prevents the bolt from being broken and ensures the safety when the automobile runs.
Description
Technical field
The utility model relates to the improvement technology of bolt arrangement.
Background technique
At present the structure of bolt is that connection part at screw rod and bolt head is provided with one section cylindrical body, with the packing ring of bolt matching etc. be to be set in this above cylindrical body.The automobile upper-part is general at present uses above-mentioned bolt to connect.But when this type bolt uses on automobile, owing to jolt during automobilism, cylindrical body and packing ring contact position smoother on the bolt, the as easy as rolling off a log bolt looseness that causes, and also to receive shearing force bigger in the cylindrical body position, and bolt fractures easily, has potential safety hazard.
The model utility content
The utility model provides a kind of automobile bolt of straight burr structure, and it is loosening easily in use with bolt that the utility model has solved existing automobile, and bolt fractures easily, causes the problem of potential safety hazard.
For addressing the above problem, the utility model adopts following technological scheme: a kind of automobile bolt of straight burr structure, comprise bolt head 1 and screw rod 2, and between bolt head 1 and screw rod 2, be connected with cylindrical body 3; Along circumferencial direction the fin 4 of vertical setting is arranged at the outer surface of cylindrical body 3, the cross section of said fin 4 is pointed shape.
The utility model is because periphery between screw rod and bolt head is provided with fin, and fin plays anti-skidding effect, when preventing the automobile action because the bolt looseness that jolts and cause; The fin that vertically is provided with in addition plays reinforing function, prevents that bolt from being fractureed, the safety when guaranteeing automobilism.
