Embodiment
The explanation of following examples is graphic with reference to what add, can be in order to the specific embodiment of implementing in order to illustration the present invention.The direction term that the present invention mentioned, for example " on ", D score, " preceding ", " back ", " left side ", " right side ", " top ", " end " etc., only be direction with reference to annexed drawings.Therefore, the direction term of use is in order to explanation and understands the present invention, but not in order to restriction the present invention.
For allowing above-mentioned purpose of the present invention, feature and advantage become apparent, preferred embodiment of the present invention cited below particularly, and conjunction with figs. are described in detail below:
Please also refer to Fig. 1 and Fig. 2, Fig. 1 is the exploded perspective view of press testing rod capable of finely adjusting error preferred embodiment of the present invention; Fig. 2 is the assembled sectional view of press testing rod capable of finely adjusting error preferred embodiment of the present invention; Press testing rod capable of finely adjusting error 10 of the present invention comprises pipe 20, one depression bar 30, a contact block 40.Seat pipe 20 is a body, which kind of shape external diameter is not restricted to, and it can be installed in one and push on the test machine, by push test machine drive to the touch screen or the button of electronic goods push, test such as friction, its driving back and forth be configured to common mechanical mechanism, will not describe in detail in this.
The two ends outside surface of seat pipe 20 is provided with screw thread, and the center is provided with the through hole 21 of perforation, and through hole 21 voltage supply bars 30 and a spring 24 are inserted.The upper/lower terminal of seat pipe 20 is screwed into cap 22 on, cap 23 once with screw-in version respectively, and 22,23 of upper and lower caps are not provided with dead eye 221,231, and depression bar 30 can slide in through hole 21 smoothly by the support of dead eye 221,231.Upper and lower cap 22,23 the bests are made by copper, plastics, pottery or the materials such as alloy with capillary through holes.Length the best of the upper end screw thread of seat pipe 20 outside surfaces is stated 1/3rd to 1/4th of a length of tube, relative, length the best of last cap 22 also is 1/3rd to 1/4th of seat pipe 20 length, so goes up cap 22 and manages 20 relatively the bigger adjustment distance that moves can be arranged.Hold-doun nut 25 can not shaken cap 22 and displacement arbitrarily in order to the fixing last cap of adjusting after finishing 22 in test is carried out.
One end of depression bar 30 combines with contact block 40, and contact block 40 is made for rubber-like materials such as rubber, silica gel, and it can scratch product to be measured in order to contact with button or screen to be tested.Depression bar 30 is provided with a projection 31.
Please refer to the assembled sectional view of Fig. 2 press testing rod capable of finely adjusting error preferred embodiment of the present invention.Spring 24 is placed in the through hole 21 of seat pipe 20, and the upper end stays on the inner bottom of cap 22, the projection 31 of lower end pushing and pressing depression bar 30, and when spring 24 was upheld fully, projection 31 relied on down the inner bottom of cap, made depression bar 30 can not break away from seat pipe 20.
Please refer to Fig. 3, Fig. 3 is the action synoptic diagram of Fig. 2.Test is the below that electronic product to be measured is placed test machine when carrying out, press testing rod capable of finely adjusting error 10 is adjusted in alignment with directly over the electronic goods button to be measured, start after the test machine, driving whole press testing rod capable of finely adjusting error 10 pumps, or translation about, about, the mode of the drawing a circle touch screen that rubs, make the quality and the life-span of contact block 40 continuous repeated presses or friction testing product to be measured.When the contact of contact block 40 repetitions is tested, contact block 40 is pushed by the product reacting force, pushing tow depression bar 30 upwards, and by projection 31 compression springs 24, the strength that spring 24 is accumulated answer promptly equals the size of pressing force, and after a period of time was carried out in test, spring 24 produced flexible tired, and then the pressing force that makes original setting then must be adjusted when producing error.
The pressing force that the please refer to Fig. 4 press testing rod capable of finely adjusting error preferred embodiment of the present invention synoptic diagram that calibrates for error.After through long test, spring 24 produces elastic fatigue, make the pressing force of original setting produce error, loosen fixed screw 25 during calibration error earlier, away from last cap 22 1 segment distances, rotation is gone up cap 22 and is adjusted the relative position of cap 22 and projection 31 in the change then, can change the spread length of spring 24, make it consistent by the testing tool calibration again with predefined pressing force.
Press testing rod capable of finely adjusting error of the present invention can be installed in the test machine of various types easily, carries out the test of life-span or quality with screen or button to electronic product.When the elastic fatigue phenomenon appears in spring 24, can finely tune the calibration pressing force, press testing rod capable of finely adjusting error simple structure of the present invention, maintenance easily and can be finely tuned correction error, guarantee that test obtaining result accurately.
Certainly, more than only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.In addition to the implementation, the present invention can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the present invention's scope required for protection.
