The fire retardancy test case
Technical field
The utility model relates to a kind of burning pick-up unit, relates in particular to a kind of fire retardancy test case of automotive upholstery.
Background technology
Use existing fire-retardant case to carry out the automotive upholstery burning test and be mainly the 3 kinds of situations that test out, once being not burn the first graticule flame to extinguish, the 2nd, extinguish after burning first graticule, the 3rd, burn second graticule and also do not extinguish, judge the flame retardant effect of institute's testing automobile inside gadget by the standard that these three kinds of situations occur.Existing fire retardancy test case is when the third situation occurring, and flame can not extinguish automatically, needs the people for extinguishing, and does both inconveniences like this, and the safety of testing crew is had certain harmfulness.
Chinese patent notification number CN101464452A has announced a kind of testing apparatus of yarn fire resistance June 24 2009 day for announcing, belongs to the Textile Engineering field.Testing apparatus comprises the burning test case, be provided with sample holder along 45 ° of directions of base plate angle in the burning test case with the burning test case, be provided with lighter between sample holder and the base plate, the sample holder middle part is provided with openwork part, the openwork part upside is provided with back-up block, the back-up block middle part is provided with Yarn clamper, also is provided with tensioner in the burning test case.The to be measured yarn beam of method of testing for being connected with tensioner with the Yarn clamper clamping, the sample holder that clips yarn beam to be measured is placed in the burning test case, treat the igniting of survey yarn beam with time set reference mark firearm, measure afterflame and glow the time, under yarn beam clamped condition to be measured, directly measure char length.This device is directly tested the yarn anti-flammability, better, simple with other method of testing correlativity, quick and precisely, be widely used, cost is lower.But this device is after finishing test, and sample does not burn down and can not extinguish automatically, needs the people for extinguishing, and both does inconveniently like this, and the safety of testing crew is had certain harmfulness, waits it to burn down fully and loses time.
Summary of the invention
The purpose of this utility model is to provide a kind of fire retardancy test case, after having solved existing fire-retardant case and finishing the automotive upholstery burning test, and the problem that flame can not extinguish automatically.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of fire retardancy test case comprises casing, and the casing front is provided with glass door, and the middle part is hung with the clamping plate carriage in the described casing, is pressed with the sample clamping plate on the clamping plate carriage, respectively has the oval groove of an identical end opening on clamping plate carriage and the pressure sample clamping plate.Accompany the exemplar of automotive upholstery between clamping plate carriage and pressure sample clamping plate, rationally offer the oval groove on clamping plate carriage and the pressure sample clamping plate, making oval channel opening end is firing tip, oval groove other end end is the second graticule place, because the exemplar of automotive upholstery is burned to test behind second graticule and finishes, the utilization method of dinching is put out a fire, flame can't not burn in having the environment of oxygen, after part is burned to second graticule, because exemplar is clipped in the clamping plate carriage and presses in the sample clamping plate, no blow vent, flame extinguishes automatically.
As preferably, be fixedly connected with some register pins on the described clamping plate carriage, press the sample clamping plate to be provided with some pilot holes, register pin and pilot hole cooperate.Press some alignment pin position fixing on some pilot holes and the clamping plate carriage on the sample clamping plate corresponding, when place exemplar on the clamping plate carriage, when pressing the sample clamping plate, pilot hole penetrates the register pin that is mated, location pressure sample clamping plate, accurate cramping exemplar.
As preferably, described casing one side is provided with side door, and the side door inner face is fixed with combustion lamp.Close the upper box side door, the combustion lamp socket is over against firing tip, and the combustion lamp switch is connected on the casing outside, can control combustion lamp duration of ignition outside casing, conveniently at the trial exemplar is lighted a fire.
As preferably, described tank floor is provided with roller, and the casing another side is provided with pull bar.When shifting casing, be convenient to the transhipment of fire retardancy test case.
The beneficial effects of the utility model are: (1), finish test back auto extinguishing, improve the testing crew security; (2), accelerated test replaces the saving test period.

Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is a kind of structural representation that the utility model is pressed the sample clamping plate.
Among the figure: 1, casing, 2, side door, 3, the clamping plate carriage, 4, register pin, 5, press the sample clamping plate, 6 combustion lamps, 7, pilot hole, 8, glass door, 9, roller, 10, pull bar.
Embodiment
Below by specific embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described specifically:
Embodiment 1: as shown in Figure 1, a kind of fire retardancy test case, comprise casing 1, casing 1 is a rectangular parallelepiped, casing 1 front is furnished with glass door 8, casing 1 left side has side door 2, side door 2 inner faces are fixed with combustion lamp 6, respectively there is a roller 9 casing 1 bottom surface for four jiaos, casing 1 right flank middle part is fixedly connected with pull bar 10, the middle part is hung with clamping plate carriage 3 in the casing 1, have the oval groove of an end opening on the clamping plate carriage 3, the even stationary arrangement in clamping plate carriage 3 upper surface oval groove both sides has two each three register pin 4 of row, is pressed with sample clamping plate 5 on the clamping plate carriage 3, as shown in Figure 2, press have on the sample clamping plate 5 with clamping plate carriage 3 on the oval groove of an identical end opening, press the even stationary arrangement in sample clamping plate 5 upper surface oval groove both sides that two each three pilot hole 7 of row are arranged, register pin 4 and pilot hole 7 match on the clamping plate carriage 3, be the first graticule place of combustion standard from nearest register pin 4 places of oval channel opening end on the clamping plate carriage 3, oval groove other end end is the second graticule place on the clamping plate carriage 3.
Use the fire retardancy test case that the exemplar of automotive upholstery is tested, open casing face glass door 8, take off and press the sample clamping plate, on clamping plate carriage 3, place exemplar, put and press sample clamping plate 5 to press exemplar, shut glass door 8, check the combustion lamp 6 in the side door 2, shut side door 2 after checking well, light exemplar by external switch control combustion lamp 6, observe the exemplar burning, three kinds of situations might appear in burning test, once being not burn the first graticule flame to extinguish, the 2nd, extinguish after burning first graticule, the 3rd, burn second graticule and also do not extinguish, extinguish automatically after crossing second graticule, according to different situations, judge the flame retardant effect of this automotive upholstery.
Above-described embodiment is a kind of preferable scheme of the present utility model, is not that the utility model is done any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim puts down in writing.
