Abstract

The invention discloses a mechanical lifting device capable of being expanded and adjusted. The device comprises a lifting main body, a ratchet wheel handle and a supporting frame, wherein the liftingmain body comprises a lifting base, a base, a screw rod, hinge plates and contraction blocks, the lifting base and the base are oppositely arranged, the screw rod is located between the lifting baseand the base, the screw rod is in threaded connection with the two contraction blocks, four hinge plates are arranged on each of the left side and the right side of the lifting base and the base, theupper ends of the first hinge plate and the second hinge plate in the four hinge plates are hinged to the lifting base, the lower ends of the third hinge plate and the fourth hinge plate in the four hinge plates are hinged to the base, the lower ends of the first hinge plates and the upper ends of the third hinge plates are hinged to one contraction block, and the lower ends of the second hinge plates and the upper ends of the fourth hinge plates are hinged to the other contraction block; and the ratchet wheel handle is installed at the end of the screw rod and can drive the screw rod to rotate, and when the screw rod rotates, the two contraction blocks move close to each other or away from each other, so that the lifting base ascends and descends relative to the base. According to the device, uniform lifting force can be applied to the periphery of a daughter board.

Description

technical field [0001] The invention relates to the technical field of connector insertion, in particular to an expandable and adjustable mechanical lifting device. Background technique [0002] With the continuous advancement of science and technology, the requirements for miniaturization of equipment are getting higher and higher. The printed boards inside many equipment adopt the installation form of the main board and the sub-board. The sub-board and the main board are usually directly connected through multiple multi-core connectors. Plug connection to reduce the size. But this will cause a problem, that is, when the number of connectors and the number of cores of the connector are large, the friction of the connector is relatively large, and the connector is difficult to unplug. damage. Contents of the invention [0003] The purpose of the present invention is to provide an expandable and adjustable mechanical lifting device, which can apply a uniform lifting force...
