Description

Dustproof test box structure Technical Field The utility model relates to the technical field of dustproof test boxes, in particular to a dustproof test box structure. Background A dust proof test chamber is a device for simulating a climatic environment. The apparatus helps to evaluate the ability of the equipment to resist the effects of dust that may clog openings, infiltrate crevices, bearings and joints, without degrading performance, reliability and maintainability due to the abrasive or obstructive effects of large grit with sharp edges. For evaluation of all mechanical, optical, electrical, electronic, electromechanical and electrochemical devices that may be exposed to dry blowing, dusting atmosphere or dust conditions. When the existing dustproof test box is used, dust blown out by the dust outlet pipe is easily concentrated to be blown to the inner box top, so that the dust diffusion effect is general, the state that the dust diffusion falls to tested equipment is influenced, the test effect is influenced, meanwhile, when the existing test box is used, the dust collection opening of the dust collection pipe in the dust collection hopper is upward, the dust is easily blocked by the dust collection opening under the action of gravity, and the dust blowing effect is influenced. Disclosure of utility model The utility model aims to overcome the existing defects, and provides a dustproof test box structure, and through the dust dispersing ball, dust blown out of a dust outlet pipe can uniformly diffuse and fall when encountering the dust dispersing ball, so that the dust can uniformly fall on a tested object, the test effect is ensured, and the problems in the background technology can be effectively solved. The dustproof test box structure comprises an outer box body, wherein an inner box is arranged on the inner side of the outer box body, dust dispersing balls are arranged on the inner top side of the inner box, dust outlet pipes are arranged on the inner side surfaces of the inner box, air outlets of the dust outlet pipes are aligned to the positions of the dust dispersing balls, dust collecting hoppers are arranged on the lower portions of the inner box, dust collecting pipes transversely penetrate through the inner bottom sides of the dust collecting hoppers, dust collecting openings are formed in the lower side surfaces of the dust collecting pipes at equal intervals, and vibration motors are arranged on the lower side surfaces of the dust collecting hoppers. Further, a box door is arranged on one side face outside the outer box body, a compression nut is arranged on one side face of the box door, and a threaded rod is arranged in the center of the compression nut in a penetrating mode.
