Abstract

The invention discloses a thread self-locking type manual clamping fixture which comprises an L-shaped supporting plate, a n-shaped pressing plate, a threaded rod and a compression nut. The middle portion of the L-shaped supporting plate is rotatably connected with the lower end of the threaded rod through a first hinge pin. One end of the L-shaped supporting plate is rotatably connected with one end of the n-shaped pressing plate through a second hinge pin. The upper end of the threaded rod penetrates through an unthreaded hole in the middle of the n-shaped pressing plate and then is provided with the compression nut. An anti-skid gasket is arranged between the compression nut and the n-shaped pressing plate. A first pressure foot is fixedly arranged at the open end of the L-shaped supporting plate. A second pressure foot matched with the first pressure foot is fixedly arranged at the open end of the n-shaped pressing plate. The thread self-locking type manual clamping fixture has the following characteristics of being reasonable in design, simple in structure, convenient to operate, small in size, low in weight, convenient to mount and dismount, reliable in clamping, large in force increasing ratio, good in self-locking performance, low in production cost and convenient to use and popularize.

Description

technical field [0001] The invention relates to a clamping device, in particular to a threaded self-locking manual clamping fixture. Background technique [0002] At present, clamping devices are widely used in all walks of life. Clamping devices generally adopt wedge clamping, eccentric clamping, centering clamping or hinge clamping. The above clamping methods have structures and manufacturing processes. Relatively complex, relatively small boost ratio and other issues. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art and provide a threaded self-locking manual clamping fixture, which has reasonable design, simple structure, convenient operation, small size, light weight, convenient disassembly and assembly, and reliable clamping. The booster ratio is large, the self-locking performance is good, the production cost is low, and it is easy to popularize and use. [0004] In order to ach...
