Abstract

The invention relates to a nonlinear curve eccentric cam type quick clamping device. When a handle of a nonlinear curve eccentric cam is closed, the eccentric cam reaches a highest point to realize a clamping function; the curve surface of the cam is a nonlinear curve surface, and a self-locking and anti-falling function is realized; when a spanner is pulled, the eccentric cam reaches a lowest point, and under the action of a tension spring, a fixed slip groove and a movable slip groove are loosened. In the invention, the clamping force is regulated through regulating the connecting threads of a pull rod sleeve and a pull rod shaft, thus the eccentric cam can be used for realizing the functions of quickly assembling and disassembling, quickly clamping, self-locking and preventing loosening. The eccentric cam has the advantages of compact structure, small size, light weight, convenience for operation, and the like and solves the problems of slower mounting, complicated operation and low efficiency of the traditional clamping device.

Description

technical field [0001] The invention relates to a clamping device, in particular to a nonlinear curve eccentric cam type quick clamping device. Background technique [0002] At present, sights, front handles of rifles, etc. are mostly installed by screw tension, and generally need to be equipped with accessories such as wrenches. In actual use, not only is it inconvenient to carry, but also time-consuming and laborious to install and disassemble. There is also a quick clamping through the friction force of the inclined plane, which is actually equivalent to increasing the pitch of the thread. It also requires auxiliary tools to achieve clamping, and the actual efficiency is not high. [0003] In addition, in other similar guide rail installations, screw tensioning installations or screw compression installations are generally used, and accessories such as wrenches must be equipped with tools such as wrenches. The installation is slow, and tools need to be carried at any time...
