Description
TECHNICAL FIELD
[0001] The utility model relates to bolt technical field, specifically a kind of anti-inclination bolt. BACKGROUND
[0002] Various bolts are needed in the assembly link of automobile, when installing bolt, some installation positions are open type, and some assembly positions are hidden type or not friendly to human engineering, when fastening, it is easy to be off-center, damage accessory, even sometimes scratch vehicle body etc., bring high repair cost. It needs to prevent bolt from being inclined during installation, and the bolt is convenient to use. SUMMARY
[0003] To solve the problems in the above background art, the utility model aims at providing an anti-inclination bolt, which comprises a bolt head, a bolt rod and a guide end, the bolt head is connected to the bolt rod, the bolt rod is a cylindrical body with external threads, the bolt rod is connected to the guide end, and the guide end is provided with external threads.
[0004] The guide end is a triangular prism structure, and the cross section is a convex three-sided arc with equal arc length.
[0005] The guide end is a cylindrical structure, and the cross section is a circle.
[0006] The guide end and the bolt rod are concentrically arranged.
[0007] The longest distance from the center of the cross section of the guide end to the arc is less than or equal to the radius of the cross section of the bolt rod.
[0008] Compared with the prior art, the utility model can quickly adjust the inclination angle to the correct angle when the bolt is inclined and screwed into the internal thread, effectively prevents the bolt from being inclined and the subsequent problems, is more convenient to use, and improves the assembly efficiency. BRIEF DESCRIPTION OF DRAWINGS
[0009] Fig. 1 It is a structural schematic view of the utility model embodiment one.
[0010] Fig. 2 It is an inclined side view of the utility model embodiment one.
[0011] Fig. 3 It is an inclined side view of the utility model embodiment two. DETAILED DESCRIPTION
[0012] The utility model will be further described below according to the drawings. Embodiment one
[0013] As Figs. 1-2As shown, the bolt head 1 is connected to the bolt shank 2, which is a cylinder with external threads. The bolt shank 2 is connected to the guide end 3, which is provided with external threads 4. The threads make it easier to install the bolt.
[0014] The guide end 3 is a triangular prism structure, and its cross section is a circular arc convex triangle with three arc-shaped sides and equal arc lengths.
[0015] The guide end 3 and the bolt shank 2 are concentrically arranged. The longest distance from the center of the section of the guide end 3 to the arc is less than or equal to the section radius of the bolt shank, so that the force transmission of the bolt is uniform.
[0016] During use, the anti-tilt bolt is screwed into the accessory. If a tilt angle occurs, the guide end 3 assists in adjusting the angle so that the anti-tilt bolt returns to the correct angle and does not get stuck with the internal threaded hole, thereby improving assembly efficiency. Example 2
[0017] like Fig. 3 As shown, this embodiment only describes the differences from the first embodiment, and the similarities are not repeated.
[0018] The difference between this embodiment and the first embodiment is that the guide end 3 is a cylindrical structure, and its cross section is circular.
