The automobile parts processed by the industrial aluminum profiles are fixed by screws, and the safety factor required by the automobile is very high, so that the connection between the parts needs to be firm. Because the automobile needs to be maintained and repaired frequently, the bolt and the aluminum profile need to be disassembled and then assembled, the fixing force of the common bolt is gradually weakened when the common bolt is reassembled after being disassembled for many times, and the safety performance of the automobile can be threatened; and purchase supporting screw again, difficult assurance quality on the one hand, on the other hand is comparatively extravagant former material.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a fixed screw of using of automobile industry aluminium alloy, this kind of fixed screw of using of automobile industry aluminium alloy is fixed effectual to the aluminium alloy, but moreover a lot of recycle not only improves the utilization ratio to the screw, but also can improve the security performance of car.
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a fixed screw of using of automotive industry aluminium alloy, includes screwhead, the screw body, screw rod and screw cap, screwhead, the screw body, screw rod and screw cap integrated into one piece, the screw body surface is equipped with screw thread and clamping face, screw rod diameter size is no longer than screw body external diameter size. The locking surface can reduce the locking moment between the screw and the aluminum profile, increase the withdrawing moment between the screw and the aluminum profile and enhance the fixing effect of the screw on the aluminum profile.
Further, the screw head is in a cone shape. The screw is conveniently pushed into the aluminum profile.
Preferably, the locking surface is arranged on two adjacent groups of threads in a penetrating manner and is formed by cutting threads in a staggered tooth layout formed by arranging two diamonds. The staggered tooth layout can ensure that the disconnected thread group forms staggered threads, and the fixing effect of the screw on the aluminum profile is enhanced.
Furthermore, a groove is formed in the locking surface, and the depth of the groove is the distance between the disconnected thread groups. The groove enables the depth of the thread with the locking surface disconnected to be deep, so that the aluminum profile is not easy to move with the screw, and the fixing effect of the screw on the aluminum profile can be further enhanced.
Preferably, the locking surface is arranged between two groups of adjacent threads, and the two groups of adjacent threads are respectively combined into a curved surface by two sections of circular arcs at the bottom after being expanded outwards. Two corners of the curved surface formed by the outward expansion of the adjacent threads can form a locking surface with the surface of the aluminum profile, so that the fixing effect of the screw on the aluminum profile is enhanced.
Furthermore, a fixing groove is formed in the center of the screw cap, and the depth of the fixing groove is smaller than that of the screw cap. The fixing groove facilitates operation of the screw.
Further, the fixing groove is hexagonal.
Further, the screw still includes the gasket, the outside of the screw pole is located to the gasket cover, the external diameter size of gasket equals the diameter size of screw cap. The gasket can increase the fixing effect of the screw on the aluminum profile.
Further, the gasket is made of copper metal. Good sealing effect, wide source and abrasion resistance.
Has the advantages that: compared with the prior art, the utility model has the advantages of it is following: the utility model provides a screw for fixing aluminum section bar in automobile industry, which can reduce the locking torque between the screw and the aluminum section bar, increase the withdrawal torque between the screw and the aluminum section bar, and enhance the fixing effect of the screw to the aluminum section bar; the groove deepens the depth of the broken thread of the locking surface, so that the aluminum profile is more difficult to move with the screw, and the fixing effect of the screw on the aluminum profile can be further enhanced; the staggered tooth layout can ensure that the disconnected thread group forms staggered threads, and the fixing effect of the screw on the aluminum profile is enhanced; two corners of a curved surface formed by the outward expansion of the adjacent threads can form a locking surface with the surface of the aluminum profile, so that the fixing effect of the screw on the aluminum profile is enhanced; the gasket can increase the fixing effect of the screw on the aluminum profile.
