Embodiment
In order to make objects and advantages of the present invention clearly understand, below in conjunction with embodiment, the present invention is specifically described.Should be appreciated that following word only in order to describe one or more concrete embodiments of the present invention, considered critical is not carried out to the protection domain that the present invention specifically asks.
The present invention adopts as Fig. 1, 2, 3, 4, 5, technical scheme shown in 6 is implemented, a kind of portfire for cone calorimetry, cone calorimetry comprises screen layer 15 and lighter, screen layer 15 is connected with its driving mechanism carrying out movement of regulation and control, frame is provided with the first control handle 21 that check point firearm carries out movement, the transmission component that driving mechanism comprises the second control handle 22 and arranges between the second control handle 22 and screen layer 15, first, two control handles are articulated and connected with the frame of cone calorimetry respectively, the firing circuit of lighter 16 has been arranged in series first, two microswitches, 32, first, two control handles are respectively with first, two microswitches, 32 are connected.
Concrete scheme is, as shown in Figure 4,5, first and second microswitch, 32 model be cherry d45u-vd.Cone calorimetry comprises radiant cone 14, screen layer 15, lighter 16, sample box 13, weighing instrument 12 and casing 11.Specifically acting as of each parts: be provided with electric elements in casing 11, casing 11 covers as workbench and supporting spokes pencil 14 assembly, and platform is laid weighing instrument 12, weighing instrument 12 is laid sample box 13, sample box 13 is built with test specimen; Radiant cone 14 is equipped with heater element, and heating makes test specimen burn, and lighter 16 is auxiliary firing combustion; Screen layer 15 is the heat transmission of radiation-inhibiting cone 14 before the test.
Screen layer 15 is first and second plate composition of two halves circle, first and second plate is separately fixed at the upper end of first and second rotating shaft 151 that two vertical shapes are arranged, the lower end of first and second rotating shaft 151 is connected as a single entity by synchrodrive assembly, one end of second control handle 22 is connected with the first rotating shaft or the second rotating shaft and both are arranged vertically, second microswitch 32 is arranged on the side of the second operating grip 22 link, and synchrodrive assembly comprises the synchrodrive belt 152 arranged between gear and gear that first and second rotating shaft 151 is arranged respectively.Lighter 16 is fixed on the lower end of the 3rd rotating shaft that vertical shape is arranged, the first operating grip 21 is connected with the upper end of the 3rd rotating shaft, and the first microswitch is arranged on the side of the first operating grip 21 link.
By rotating the second control handle 22, making the positive and negative rotation of first and second rotating shaft, driving folding and closedown, as shown in Figure 3,4, depressing the second microswitch when the second control handle 22 goes to the left side, connect ignition circuit; Leave the second microswitch when the second control handle 22 goes to the right, disconnect ignition circuit, first and second plate only moves horizontally.Handle lighter 16 by the first control handle 21 to swing, when lighter 16 is put to sample box 13 center, first control handle 21 depresses the first microswitch, connect ignition circuit, when lighter 16 is put to sample box 13 outer fix, first control handle 21 leaves the first microswitch, disconnects ignition circuit.
