Description
Technical field
The utility model relates to the test of touch-screen strength of glass, particularly relates to the steel ball fall-down test device that is used for the test of touch-screen strength of glass, is a kind of proving installation of simple and easy practicality.
Background technology
China's utility application 200410000638.1 discloses a kind of strength of glass warranty test method, and it may further comprise the steps: 1, for glass to be measured, and the intensity guarantee value σ that a given expectation reaches
s, the pressure ball of selected known radius and elastic constant is according to the corresponding relation between critical load and the glass local strength, by desired intensity guarantee value σ
sObtain corresponding intensity and guarantee load p
s2, by loading equipemtn described spherical indenter vertically is pressed in tested glass surface, and is loaded on desired intensity assurance load p gradually
s, unload after the stop several seconds; 3, observe tested glass surface and a hertz crackle whether occurred,, illustrate that the local strength of tested glass is higher than desired intensity guarantee value σ if a hertz crackle do not occur
sIf a hertz crackle occurs, illustrate that the local strength of tested glass is lower than desired intensity guarantee value σ
sThis method not only can be carried out block-by-block to glass and be detected, and can protect detected glass under non-destructive situation, knows that definitely which piece is qualified, and which piece is defective.Even in a glass product, can measure which position intensity height, which position intensity is low.This utility model is applicable to glass component on-line testing and the monitoring under the service state, and different glass relatively and estimate.But this method need be determined intensity guarantee value σ
s, and need loading equipemtn and determine to add load P
s, the test relative complex, cost is higher.
Existing simple and easy touch-screen strength of glass steel ball proving installation as shown in Figure 1, comprise test platform 1, support 2, have the cross bar 3 of through hole, during test, touch-screen glass is placed on the platform, steel ball falls from the through hole 3 that is arranged in support 2 and has the cross bar 3 of through hole, determines that by estimating steel ball falls the position of hitting glass.Steel ball fall-down test important problem point is to guarantee that steel ball will drop on the testing sample center position, locking ball falls the position of hitting glass because by estimating accurately, fall glass by the hole that falls from test ball with eyes range estimation steel ball from testing jig top and must location put and have bigger error, retrodeviate from test point thereby cause steel ball to fall.
The utility model content
At the deficiencies in the prior art, the utility model proposes a kind of steel ball that guarantees and accurately drop on the steel ball fall-down test device that is used for the test of touch-screen strength of glass of test point.
The purpose of this utility model is achieved through the following technical solutions:
A kind of steel ball fall-down test device that is used for touch-screen strength of glass test comprises test platform, support and has the cross bar of through hole that the support lower end is arranged on the test platform or is arranged on test platform one side, and the cross bar that has through hole is fixed on the support upper end; This device also comprises hollow straight tube; The hollow diameter of straight tube use steel ball size greater than test, the through hole flexible connection in straight tube and the cross bar that has through hole.
For further realizing the purpose of this utility model, described hollow straight tube is preferably transparent hollow straight tube.
Described hollow straight tube is preferably the hollow straight tube that plastics are made.
Described hollow straight tube is preferably transparent plastic hollow straight tube.
The cross bar that described band forms through hole evenly is provided with a plurality of threaded holes in the periphery of through hole, and a plurality of threaded holes are connected with screw respectively.
Compared with prior art, the utlity model has following advantage:
The utility model device aligns with through hole owing to straight tube one end, the other end and touch-screen glass test point center-aligned to be measured, test ball is fallen from through hole, because the guide effect of hollow straight tube, thereby guarantee that steel ball meets touch-screen glass test point central point to be measured.Whole device is simple, and practicality has stronger practicality.
Description of drawings
Fig. 1 is existing simple and easy touch-screen strength of glass steel ball proving installation structural representation;
Fig. 2 is used for the steel ball fall-down test apparatus structure synoptic diagram of touch-screen strength of glass test for the utility model.
Specific implementation method
Below in conjunction with drawings and embodiments the utility model is further described, but embodiment does not constitute the restriction to the claimed scope of the utility model.
As shown in Figure 2, the steel ball fall-down test device that is used for the test of touch-screen strength of glass, comprise test platform 1, support 2 and have the cross bar 3 of through hole, the support lower end is arranged on the test platform or is arranged on test platform one side, and the cross bar 3 that has through hole is fixed on the support upper end; This device also comprises hollow straight tube 4; The hollow diameter of straight tube use steel ball size greater than test, through hole 3 flexible connections in straight tube and the cross bar that has through hole.This flexible connection can be evenly to be provided with a plurality of tapped through holes in the through hole periphery of being with the cross bar 3 that forms through hole, preferred 3 tapped through holes, each tapped through hole is connected with screw thread respectively, be fixed on straight tube 4 in the through hole by screw, this movable connection method can pass through to adjust the degree of depth of screw in through hole, and then can select the straight tube 4 of different-diameter for use.This flexible connection can also directly be threaded straight tube 4 with through hole in the cross bar that has through hole 3, even straight tube 4 is placed in the through hole in the cross bar 3 that has through hole with hand by the user.
