Handle strength testing device

Abstract

The invention provides a handle strength testing device which comprises a frame, a testing unit and a control unit, the testing unit comprises a vertical rod and a testing assembly installed on the vertical rod, and the two ends of the vertical rod are installed at the top and the bottom of the frame respectively. The testing assembly comprises a hanging piece used for installing a sample, a motorused for driving the hanging piece to vertically move along the vertical rod and a force sensor used for measuring the tensile force borne by the hanging piece, and the force sensor and the motor arein communication connection with the control unit. According to the handle strength test device provided by the embodiment of the invention, a static strength test or a dynamic strength test can be carried out on a handle as required without repeated manual operation, diversified detection requirements are met, the detection efficiency and accuracy are improved, and a force-related curve can be drawn according to measurement data; and accurate and comprehensive data support is provided for the subsequent analysis of the strength of the handle.

Description

technical field [0001] The invention relates to the testing field, in particular to a handle strength test device. Background technique [0002] During the circulation and use of items, it is inevitable that they will be moved, and the handles that come with the items are usually used for handling. How to ensure that the handle of the product can withstand a certain gravity, so that the product has better reliability, is an important direction of product engineering research. The evaluation of the handle performance of existing products is generally achieved through repeated manual operations, the detection efficiency is low, the detection accuracy is poor, and for products with two symmetrical handles, it is impossible to ensure that the two handles are in the same stress state , it is difficult to obtain accurate detection results. In addition, tests conducted by manual operation can usually only obtain a single measurement value, which is difficult to meet diverse testi...
