Embodiment
As shown in Figure 1, the cabinet 1 of the folding life-span tester of PDA product of the present utility model is a general square shape, its front and top for open wide so that operation also can be stamped dismountable transparent casing.Admittedly put the bottom that platform 11 is installed in cabinet 1, have on it and put device admittedly, be used for putting admittedly the PDA product.Drive motor 9 and the crank 7 that links to each other with the output shaft of motor, connecting rod 8, renovate anchor clamps 10 and constitute motion parts, anchor clamps 10 are clamped and are renovated during test, this renovates the rocking bar that constitutes crank and rocker mechanism, renovates so just in the action that constantly opens and closes, to realize the purpose of test.Panel 4 is positioned at a side of cabinet, comprises being used to import the importation 3 of motor speed and the display part 5 of rotating speed and number of times.Be used for being positioned at the below of panel 4, with panel and baffle plate control device being covered in usually for consideration attractive in appearance according to the control device (not shown) of input value control motor speed and number of times.
Can show current rotating speed of motor on the panel of this tester, this value is imported by the importation by the operator.In addition, also can demonstrate the number of times that adds up, with as the foundation of judging that this product is whether qualified.All right numerical value reset button 2 after a product test is intact, is pressed reset button, so that the tested product of the next one is counted again on panel.
In order to test the folding life-span of two PDA products simultaneously, can comprise that two are renovated anchor clamps, wherein first anchor clamps link to each other with connecting rod, and second anchor clamps are coupled by parallelogram lindage, are synchronized with the movement to realize renovating for two.
For determining the initial point of motion, this tester can also comprise the connecting rod mounting and fixing support, the position of stationary links when the PDA product is installed, and the motion of connecting rod should not interfered in the position of this fixed mount.
In when test, the PDA product is held device and is fixed on admittedly and puts on the platform.Have mounting groove on the platform admittedly put, the clamper that is used for fixing the PDA product is slidably located in the groove, thereby can regulate clip position according to the physical size of product.
As shown in the figure, clamper comprises nut, the compressing tablet that can slide, the bolt that passes compressing tablet and cooperate with nut in mounting groove, and during test, compressing tablet contacts with the PDA product and is fixed.
Although described the utility model with reference to the accompanying drawings, scope of the present utility model is not limited to specific embodiment, and those of ordinary skill in the art can carry out various distortion and equivalent transformation to the utility model in spirit and scope of the present utility model.
Fig. 3 is the guidance panel figure of this tester.Two switches are arranged on the panel, and one is power switch, and another is system's reset switch.Also have one 4 * 4 film key on the panel, the interface as the parameter setting and the function setting input of tester has 0-9 numerical key on this film key, starts in addition, stops, function keys such as time-out, storage, speed setting, number of times setting.The start key effect is to make tester begin to test; The stop key effect is to stop test; The Pause key effect is the Break-Up System test; The storage key effect is that current testing time and parameter are preserved; The effect of speed setting key is that the tester test frequency is set; The effect of number of times setting key is to preset testing time.Also have 3 groups of light-emitting diode displays on the panel, show respectively and preset testing time, preset test speed, actual testing time.
