Abstract
The utility model discloses an eye shield impact test device, which comprises a clamp seat, a scale frame and a cross beam, wherein the clamp seat is used for fixing eye shields, the scale frame is in vertical arrangement, the cross beam is hung on the scale frame, an electromagnet with a switch and an impact ball capable of being magnetically sucked under the electromagnet are fixedly arranged on the cross beam, and in addition, a vertically downward laser lamp is arranged under the electromagnet. The test device has the advantages that the structure is simple, the accuracy of the impact intensity and the impact position can be ensured, and parameters of tests in many times become identical.
Description
Technical field
The utility model relates to the apparatus for impact testing technical field, specifically is meant a kind of apparatus for impact testing of cover glass.
Background technology
The security protection series products must carry out the anti-impact force test before dispatching from the factory.Yet; For the cover glass product; Its impact resistance requires the product much smaller than one type of safety helmet, and therefore from practical application and cost angle, its anti-impact force testing apparatus need not to accomplish complicacy and high automation degree as safety helmet shock resistance testing apparatus; On the other hand,, do not represent that its requirement for measuring accuracy is also low, therefore need to guarantee to reach each item testing standard equally though simple testing apparatus is adopted in the shock resistance of cover glass test; In the practical application, the shock resistance testing apparatus of cover glass is often too simple, can't strictly control each item testing standard, and especially in key indexs such as impact dynamics and impact position, the consistance control of accuracy control and repeatedly test is difficult to realize.
The utility model content
The utility model technical matters to be solved provides a kind of simple in structure and can guarantee accurately and the repeatedly consistent cover glass apparatus for impact testing of test of impact dynamics and impact position.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is following:
A kind of cover glass apparatus for impact testing comprises in order to the fixing clamping fixture seat of cover glass, vertically disposed calibrating jig and hang on the crossbeam on the calibrating jig; But the electromagnet and the magnetic that are fixed with belt switch on the said crossbeam invest the impact ball of electromagnet below, and this electromagnet below is provided with vertically downward a laser lamp.
Further, said crossbeam can be fixed in the arbitrary height of calibrating jig.
The beneficial effect of the utility model is: ball is impacted in the absorption of switch control electromagnet; Make that the initial velocity when impacting ball falls is zero; And the height of crossbeam has guaranteed to impact the distance of fall of ball; Impact the weight of ball in addition and confirm, therefore impact the dynamics of pellet impact cover glass to be measured and confirm also can calculate; And the electromagnet below is provided with laser lamp vertically downward, can begin front irradiation to the cover glass relevant position in test, and the light path of laser lamp is parallel with impact ball whereabouts route, can confirm to impact the accurate position of pellet impact cover glass thus; At the crossbeam height and impact under the constant situation of ball, the parameter of repeatedly measuring reaches unanimity.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explanation:
Fig. 1 is the structural representation of the utility model cover glass apparatus for impact testing.
Embodiment
With reference to figure 1, a kind of cover glass apparatus for impact testing comprises in order to the fixing clamping fixture seat 1 of cover glass, vertically disposed calibrating jig 2 and hang on the crossbeam 3 on the calibrating jig 2; But be fixed with the electromagnet 5 of belt switch 4 and the impact ball 6 that magnetic invests electromagnet 5 belows on the said crossbeam 3, and these electromagnet 5 belows are provided with vertically downward a laser lamp 7.
Further, said crossbeam 3 can be fixed in the arbitrary height of calibrating jig 2 through the switch 8 of screwing.
Certainly; Above embodiment just is explanation rather than restriction the utility model; The above only is the preferred embodiment of the utility model, so all equivalences of being done according to the described scheme of the utility model patent claim change or modify, includes in the utility model patent claim.
Claims (2)
1. cover glass apparatus for impact testing; Comprise in order to the fixing clamping fixture seat of cover glass; Vertically disposed calibrating jig and hang on the crossbeam on the calibrating jig; It is characterized in that: but the electromagnet and the magnetic that are fixed with belt switch on the said crossbeam invest the impact ball of electromagnet below, and this electromagnet below is provided with vertically downward a laser lamp.
2. a kind of cover glass apparatus for impact testing according to claim 1, it is characterized in that: said crossbeam can be fixed in the arbitrary height of calibrating jig.
