Embodiment Construction

[0017] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0018] as attached figure 1 As shown, the present invention provides a manual and automatic integrated locking and unlocking mechanism, including a handle 1, a reduction box 2, a gear diverter 3, a left locking pin 4, a right locking pin 5 and a rack and pinion cylinder 6, wherein , a rack and a gear are arranged in the rack and pinion cylinder 6, the rack is driven by external air pressure or oil pressure in the cylinder, and moves linearly along the axis of the cylinder body, the gear is arranged above the rack, and the rack and pinion cylinder 6 is in the initial state , the gear and the rack are in a non-meshing state;

[0019] There are three bevel gears inside the gear diverter 3, one of which is a transmission gear, and the other two are output gears, and the output gears mesh with the transmission gear at the same time;

[0020] The left locking ...

Abstract

The invention discloses a manual automatic integrated locking and unlocking mechanism and belongs to the technical field of mechanical structures. The manual automatic integrated locking and unlocking mechanism comprises a handle, a reduction box, a gear steering gear, a left locking pin, a right locking pin and a gear rack cylinder. The handle is connected with the input end of the reduction box, the output end of the reduction box is fixedly connected with a transmission gear in the gear steering gear, the transmission gear is fixedly connected with a gear in the gear rack cylinder through a transmission shaft, two output gears in the gear steering gear are in threaded connection with the left locking pin and the right locking pin respectively through screw rods, and rotation of the screw rods is converted into opposite or reverse linear movement of the left locking pin and the right locking pin along the axes of the screw rods. External oil pressure or air pressure is utilized to serve as a power source to drive the left locking pin and the right locking pin to synchronously extend out or retract, a locking or unlocking function is achieved, and the manual automatic integrated locking and unlocking mechanism can simultaneously perform switching of manual operation and automatic operation according to working conditions.

Description

technical field [0001] The invention relates to an unlocking mechanism, in particular to a manual and automatic integrated unlocking mechanism, which belongs to the technical field of mechanical structures. Background technique [0002] For the mechanism that requires locking and unlocking at present, in order to improve the reliability of the mechanism, it is often necessary to have the function of automatically realizing the locking and unlocking, and at the same time, it is also required to be able to realize the above functions manually. The existing mechanism has the problem that the manual operation force is large, and the manual and automatic free switching cannot be realized. Or the above-mentioned functions can be realized but the mechanism is bulky and cannot be installed in a limited space. It is an urgent need to design a mechanism that is small in size, reliable in action, and free to switch between manual and automatic. Contents of the invention [0003] In...
