A built-in hidden thimble connecting rod type mechanical switch structure

Abstract

The invention discloses a built-in concealed thimble connecting-rod-type mechanical switch structure that comprises a base, a lock core connecting rod, a lock core push rod, a lock core pin, a repositioning unit and a pre-tightening unit and that can be used for opening or closing the upper cover of a device. By means of a connecting rod structure, vertically upward movement is converted into the rotation of the lock core pin via the rotation of a horizontal connecting rod. Thus, the lock core pin is displaced in the horizontal direction and is switched from a stationary closed state to an open state, thereby achieving the function of a mechanical switch. Compared with other mechanical structures such as magnetic buckles and door contacts, the thimble connecting-rod-type mechanical switch structure is larger in attraction force. The required opening and closing force can be adjusted by modifying the arm of force on both sides of the lock core connecting rod, and the lengths and the intersection angle of the two arms of the lock core pin. The opening and closing force and attraction force can be set differently so that a leverage effect can be achieved which is difficult to achieve in a traditional mechanical structure.

Description

technical field [0001] The invention relates to the technical field of mechanical technology and instrumentation, and more specifically relates to a built-in hidden thimble link type mechanical switch structure. Background technique [0002] In the design of scientific instruments and medical equipment, it is often necessary to take into account both aesthetics and practicality, such as the integrity and simplicity of the appearance of the instrument under normal use, and the safety and convenience of opening the instrument under adjustment and maintenance. Desktop medical equipment for users of clinical hospitals and scientific research institutions also put forward specific requirements for this. These medium-sized equipment generally involve more system components, and require users to periodically replace reagent consumables and set equipment parameters, so it involves opening The mechanical structure of an instrument's front panel, top cover, or side cover.

Problems solved by technology

[0006] In order to solve the problem that in the prior art, it is usually necessary to set obvious force-applying components such as door locks, screws, handles, switches, etc. on the surface of the instrument, and the built-in locking structures provided on the market either require equipment power supply or cannot combine safety and simplicity. , the object of the present invention is to provide a thimble link type mechanical switch structure that is easy to operate, has a large locking force and can be hidden inside the instrument
