Design method of triangular key special for triangular lock cylinder and plum blossom triangular key
The invention relates to the technical field of keys, in particular to a design method of a triangular key special for a triangular lock cylinder and a plum blossom triangular key, which comprises the following steps: using a continuous and tangent curved surface as the inner surface of the key, so that the contact between the key and the triangular lock cylinder in an ideal state is linear contact on three contact surfaces of the triangular lock cylinder; when the triangular key is rotated, the triangular key is tightly meshed with the triangular lock cylinder, and compared with the situation that the triangular lock cylinder is rounded and deformed easily when the triangular lock cylinder is rotated by a common triangular key, the contact position of the triangular key and the triangular lock cylinder is transferred, so that the triangular edge of the triangular lock cylinder is prevented from being abraded, and the service life of the triangular lock cylinder is prolonged; the invention further discloses the plum-blossom-triangle key, the plum-blossom-triangle key is designed through the method, appearance details are optimized and improved, and through modeling and finite element simulation, the triangular edges of the triangular lock cylinder are prevented from being abraded, meanwhile, overall torsional deformation of the triangular lock cylinder can be effectively relieved, and the service life of the triangular lock cylinder is prolonged. And the service life is further prolonged.
本发明涉及钥匙技术领域，具体讲是一种三角锁芯专用三角钥匙设计方法及梅花三角钥匙，包括使用连续、相切的曲面作为钥匙内表面，使理想状态下钥匙与三角锁芯的接触为三角锁芯三个接触面上的线接触；转动三角钥匙时，三角钥匙与三角锁芯咬合紧密，与普通三角钥匙转动三角锁芯时易导致三角锁芯磨圆变形的情况相比，通过转移三角钥匙与三角锁芯的接触位置，避免三角锁芯三角棱处磨损，延长三角锁芯使用寿命，本发明还公开一种梅花三角钥匙，该梅花三角钥匙使用上述方法进行设计，并对外观细节进行优化改进，通过建模并进行有限元仿真，在实现避免三角锁芯三角棱处磨损的同时，还能够有效减轻三角锁芯整体扭转变形，进一步延长其使用寿命。
