[summary of the invention]
The vibration of sand protection test unit and noise that the purpose of this utility model is to solve are on the market excessive, and serviceable life is too short, the inaccurate deficiency of test result and a kind of novel sand protection test unit that provides.
The utility model is achieved through the following technical solutions: a kind of sand protection test unit, comprise cabinet, sand filter unit, circulating device, control box, described cabinet top is provided with sand filter unit, described sand filter unit right side is provided with circulating device, described circulating device right side is provided with control box, and described control box is electrically connected to described cabinet.
Further, described control box adopts data line clastotype to be connected with described sand protection test unit.
Further, described sand filter unit involving vibrations funnel, screen cloth, vibrating motor, described Vibrating funnel below is provided with screen cloth, and described screen cloth below is provided with vibrating motor.
Further, described cabinet comprises case in casing, test, sealing canvas, spring, bottom support frame, described casing is provided with case in test, in described test, case bottom surrounding is provided with sealing canvas, in described test, case and described bottom support frame adopt bolt directly fixing, described sealing canvas and described Vibrating funnel are connected to form leakage test space, and described bottom support frame top is provided with spring, and described Vibrating funnel and described bottom support frame are fixed with spring.
Further, described circulating device comprises nylon hose, circulating fan, sand and dust circulating line, described nylon hose is positioned at described screen cloth below, described circulating fan is positioned at described nylon hose right side, described Vibrating funnel adopts nylon hose to be connected with described circulating fan, and described sand and dust circulating line is positioned at described circulating fan right side.
Further, in described test, case comprises test specimen, the outlet of sand and dust circulating line, and it is inner that described test specimen is positioned at described test case, and described sand and dust circulating line outlet is positioned at described test case top.
The beneficial effects of the utility model are:
1, the utility model has designed a set ofly by the sand protection test unit that in bracing or strutting arrangement, cabinet, test, case, vibrating device, sand and dust circulating device form, and this device provides the dirt exclusion capabilities test Solution of various electric and electronic products for client.
2, in test, case adopts canvas (also can adopt other flexible material) to be connected sealing with Vibrating funnel, avoid funnel vibration to be delivered to case in test, solved case vibration problem in test, also solved affected by vibration in test specimen test process simultaneously and cause the inaccurate problem of test result.
3, test funnel and bottom support adopt spring to fix, and have solved Vibrating funnel vibration and have been delivered to the problem of bottom support, thereby avoided the package unit shorter problem in serviceable life that causes affected by vibration.
4, Vibrating funnel adopts nylon hose to be connected with circulating fan, has solved Vibrating funnel vibration and has been delivered to the problem of circulating fan, thereby guaranteed circulating fan and sand and dust circulating device normal service life.
5, control box adopts data line to be connected this clastotype with sand protection test unit, even if sand protection test unit has microvibration, but can not be delivered to each control element yet, simultaneously, the airborne dust hiking up when this sand protection test unit being added or remove sand and dust can not invest each element yet, thereby has guaranteed each element normal service life.
