Fig. 3 is the partial enlarged drawing of I part in Fig. 2.
In figure, 1 is main frame, 2, and are time frameworks, 3 are primary and secondary frame attachment plate, 4 to be primary and secondary framework joint pins, 5 be that to fill core, 6 are rubber strips.
Detailed description of the invention
Below in conjunction with accompanying drawing, concrete structure of the present invention and technique effect are described further, to understand application of the present invention fully.
In the present invention, inner side is defined as the side towards high-low-temperature environmental testing box body, then contrary opposite side is outside
As shown in Figure 1, Figure 2 and Figure 3, the external door door leaf of high-low-temperature environmental testing case comprises: main frame 1, secondary framework 2, primary and secondary frame attachment plate 3, primary and secondary framework joint pin 4, filling core 5 and rubber strip 6.Primary and secondary frame attachment plate 3 is made up of the strip plate that four pieces are connected, and it divides with the surrounding edge of time framework 2 with main frame 1 respectively and is connected, thus forms the basic framework of template external door door leaf.The two ends of primary and secondary framework joint pin 4 are connected with main frame 1 and time framework 2 respectively, and primary and secondary framework joint pin 4 is multiple and is installed in the whole space between main frame 1 and secondary framework 2.Fill core 5 to be filled in the confined space that formed by main frame 1, secondary framework 2 and primary and secondary frame attachment plate 3, rubber strip 6, along the bearing of trend of primary and secondary frame attachment plate 3, is installed on primary and secondary frame attachment plate 3.
Main frame 1 is positioned at the inner side of external door door leaf, main frame 1 comprises the rectangle net grating texture be welded into by square steel and the stainless steel curved corrugated sheet be welded and fixed mutually with rectangle net grating texture, and the mesh of fenestral fabric adopts stainless steel curved corrugated sheet to be covered by the mode of welding.Because main frame is positioned at the inner side of external door door leaf, high and low temperature environment when residing environment is test, higher for the requirement of bearing high/low temperature, stainless steel curved corrugated sheet high and low temperature resistance is good, the deformation that high and low temperature environment causes can be born, thus ensure that the sealing function of main frame.
Secondary framework 2 is positioned at the outside of external door door leaf, and secondary framework 2 comprises the rectangle net grating texture be welded into by square steel and the Thin Stainless Steel flat board be welded and fixed mutually with rectangle net grating texture, and the mesh of fenestral fabric covered by Thin Stainless Steel flat board.Because secondary framework is positioned at the outside of external door door leaf, residing environment is extraneous room temperature environment, and for bearing the less demanding of high/low temperature, Thin Stainless Steel is dull and stereotyped just can be met, and then realizes the sealing function of time framework.
Primary and secondary frame attachment plate 3 and main frame 1 divide with the surrounding edge of time framework 2 and are connected, thus and main frame 1, form airtight space between secondary framework 2, furthermore achieved that the sealing function of external door door leaf.Primary and secondary frame attachment plate 3 is fiber glass epoxy sheet material.
According to concrete test conditions, primary and secondary frame attachment plate 3 can arrange heat tape, particularly when being used for doing low-temperature test when high-low-temperature environmental testing case, the cold air leaked out from high-low-temperature environmental testing case can form frost and condensed water at primary and secondary frame attachment plate 3, thus destroy the sealing performance of high-low-temperature environmental testing case, its heat-insulating property of further destruction, and the formation that heat tape can be used to prevent frost and condensed water is set on primary and secondary frame attachment plate 3, thus make the sealing performance of high-low-temperature environmental testing case, heat insulation effect better.
The two ends of primary and secondary framework joint pin 4 are fixedly connected with main frame 1, secondary framework 2 respectively, primary and secondary framework joint pin 4 is multiple and is installed in the whole space between main frame 1 and secondary framework 2 equably, the space that main frame 1, secondary framework 2 are formed with primary and secondary frame attachment plate 3 is divided into several little spaces, the material of primary and secondary framework joint pin 4 is fiber glass epoxy sheet material, and the structure that multiple primary and secondary framework joint pin 4 and main frame 1, secondary framework 2, primary and secondary frame attachment plate 3 are formed makes external door door leaf of the present invention have very high intensity.
Fill core 5 to be filled in the confined space that formed by main frame 1, secondary framework 2 and primary and secondary frame attachment plate 3, filling core 5 is heat insulation glass silk flosssilk wadding, thus makes the heat insulation effect of high-low-temperature environmental testing case better.
Rubber strip 6 is arranged on the primary and secondary frame attachment plate 3 of external door door leaf, and distribute along the primary and secondary frame attachment plate 3 profile surrounding circumference of external door door leaf, rubber strip 6 installs 2-3 road on primary and secondary frame attachment plate 3, rubber strip 6 further enhances sealing effectiveness, thus makes the heat insulation effect of high-low-temperature environmental testing case better.
Relative to the high-low-temperature environmental testing case of existing employing at single-store frame outer application heat insulating material, and its size existed is little, sealing effectiveness and heat insulation effect bad etc. not enough, the invention provides a kind of external door door leaf of high-low-temperature environmental testing case of new design, its main frame, secondary framework and primary and secondary frame attachment plate, the syndeton of many primary and secondarys framework joint pin, and rubber strip, it is large that heat tape and the use of filling core make external door door leaf of the present invention have size relative to prior art, heat-proof quality and favorable sealing property, the advantage that intensity is high, the requirement of the high-low-temperature environmental testing case of development can be met.
More than describe the specific embodiment of the present invention in detail.Should be appreciated that the ordinary skill of this area just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technician in the art, all should by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
