Abstract

The invention provides an adjustable pressing test bar, comprising a seat tube, a press bar, a spring, a press piece, an upper cover and a lower cover, wherein, screw threads are arranged on the outer surface at the two ends of the seat tube; a through hole is arranged at the center of the seat tube; the upper cover and the lower cover are respectively combined on the screw threads at two ends of the seat tube; the upper cover and the lower cover are respectively provide with a bearing hole; the press bar is supported by the bearing holes of the upper cover and the lower cover, can be accommodated in the hole of the seat tube in a sliding manner, is provided with a bump, and the surface of the press bar is provided with a scale; the spring is sheathed on the press bar; the press piece is combined at one end of the press bar. The pressing force of the adjustable pressing test bar can be adjusted according to the change of the position of the seat tube relative to the cover.

Description

technical field [0001] The invention relates to an adjustable pressing test rod, in particular to an adjustable pressing test rod which can adjust the pressing force, display the pressing force with a scale, and can calibrate the error of the pressing force. Background technique [0002] Electronic products such as hand-held phones, calculator keyboards, portable electronic devices, etc. have many buttons. During the manufacturing process or the finished product must pass the test to ensure the quality of the buttons. The test method is usually to use a drive-test A button testing machine with a reciprocating head, which performs fatigue testing or life testing on the buttons, such as the invention patent of "button testing machine" published in China No. CN101236147A, and the utility model patent of "button testing machine" published in China No. CN2906582Y, which is driven by air pressure The piston of the cylinder is pushed out to press the button of the electronic produc...
