Abstract
The utility model relates to the technical field of detection equipment, and in particular relates to a smoke density testing device. The smoke density testing device comprises a box body, wherein a grid frame is arranged in the box body; a sample is placed on the grid frame. The smoke density testing device is characterized in that a fixing device which is used for preventing the sample from moving is pressed against the sample; a laser is arranged above the sample; a flame temperature sensor is arranged on the lower part of the grid frame. The smoke density testing device has the beneficial effects that the fixing device is lightly pressed against the sample to prevent the sample from moving; the laser is arranged on the upper part in the box body, and a laser beam is emitted to the grid frame and is used for positioning the sample; the flame temperature sensor is arranged, on the lower part of the grid frame, below the sample and is used for determining the flame temperature. The smoke density testing device is simple in structure and convenient to use.
Description
(1) technical field
The utility model relates to checkout equipment technical field, particularly a kind of smoke density test device.
(2) background technology
When the smoke density that detects building materials burning or decompose, smoke density sample should be placed on the square-shaped frame groove of length of side 64mm, square is by 6 * 6 * 0.9(mm) Stainless steel mesh formation.The length of smoke density sample * wide * thick is for 25.4mm * 25.4mm * (former thick and be less than 25mm) so sample is very little, very light, and the standard-required flame 4min that will burn under sample measures its smoke density grade.There are the following problems for existing smoke density checkout equipment; Because Fire Radiation impulse force often makes sample, move, impact detects data.If flame-thrower nozzle is motionless, before igniting, sample should be placed on to center, there is no convenient and reliable location measure.Combustion gas is the propane of 276ka pressure and the combination gas of air, and the flame temperature of sample below can affect detection data, but flame temperature sensor is not set.
(3) summary of the invention
The utility model, in order to make up the deficiencies in the prior art, provides a kind of smoke density test device simple in structure, easy to use.
The utility model is achieved by the following technical solution:
A test device, comprises casing, and grid frame is installed in casing, above grid frame, place sample, its special character is: on sample, have pressure holding to prevent the stationary installation that sample moves, laser instrument is installed in top, flame temperature sensor is installed below grid frame.
Smoke density test device of the present utility model, stationary installation comprises fire-resistant pin, lifts depression bar, supporting seat, pressure pin, fire-resistant pin is arranged on to be lifted on depression bar, and it is hinged with supporting seat and be connected with pressure pin by extension spring that this lifts depression bar, and supporting seat is fixed on casing by pressure pin.
Smoke density test device of the present utility model, laser instrument is cross structure, and it is positioned at grid frame top, and on casing Nei top, flame temperature sensor faces sample.
Smoke density test device of the present utility model, flame temperature sensor is connected with display, and casing also arranges burner.
The beneficial effects of the utility model are: the light stationary installation of pressing above sample, prevents that sample from moving.Laser instrument is installed above casing, and laser beam is beaten in grid frame, be used for locating placing sample, and under grid frame, be, below sample, flame temperature sensor is installed, be used for measuring flame temperature, simple in structure, easy to use.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 2 is schematic top plan view of the present utility model;
