Description

Technical Field

[0001] The utility model relates to the field of thermal insulation testing, in particular to a thermal insulation material performance testing device. Background Art

[0002] Thermal insulation materials refer to materials that can block the transfer of heat flow, also known as thermal insulation materials, such as glass fiber, asbestos, rock wool, silicate, etc., new thermal insulation materials, such as aerogel felt, vacuum panels, etc., which are used for building enclosures or thermal equipment, materials or material composites that resist heat flow transfer, including both thermal insulation materials and cold insulation materials.

[0003] Publication No.: CN211697601U discloses a detection device for building material thermal insulation experiment. In order to solve the problem that most of the equipment for testing the thermal insulation of building materials are fixed and the light intensity cannot be adjusted to test their thermal insulation performance, a supporting base plate is set, a U-shaped card plate is welded on the top of one end of the supporting base plate, a material sample is vertically installed in the inner cavity of the U-shaped card plate, a positioning nut is welded in the middle of the side wall of the U-shaped card plate, and a fixing screw is installed in the inner cavity of the positioning nut; the position of the positioning slider on the top of the supporting base plate is adjusted by rotating the positioning screw, and the distance between the inspection lamp body and the material sample is adjusted. The farther the inspection lamp body is from the material sample, the weaker the light, and the closer the inspection lamp body is to the material sample, the stronger the light. The staff touches the side of the material sample that is not illuminated by the light with their hands, records the heating time, and realizes the test of the thermal insulation performance of the material sample under different light intensities, so that the staff or customers can intuitively feel the thermal insulation performance of the material sample.

[0004] In the above-mentioned prior art, the distance between the test lamp body and the material sample is adjusted to achieve the test of the thermal insulation performance of the material sample under different light intensities. However, in the device, only one group of material performance tests can be completed at the same time. When multiple groups of materials are tested at the same time, multiple groups of devices need to be used, or the tests need to be rotated, which is inefficient. For this reason, we propose an insulation material performance testing device. Utility Model Content

[0024] Specifically, the driving mechanism 7 includes a driving shaft 8, which is rotatably connected to the inside of the plate body 1. One end of the driving shaft 8 extends from one end of the plate body 1 and is fixedly connected to a handwheel 9; the handwheel 9 is used to facilitate the control of the rotation of the driving shaft 8.

[0025] The forked plate 4 is internally rotatably connected with a driven shaft 10 , and one end of the driven shaft 10 is meshed with the outer wall of the driving shaft 8 , so that the driven shaft 10 can be driven to rotate by the rotation of the driving shaft 8 .

[0027] It should be noted that the outer walls of the driving shaft 8 and the driven shaft 10 are provided with opposite threads, so that the driving shaft 8 and the driven shaft 10 with different rotation directions can move the upper material sample 6 in the same direction when rotating.

[0028] Specifically, the outer wall of the driving shaft 8 and the end of the driven shaft 10 are both provided with gear rings 12 of matching sizes for the driving shaft 8 and the driven shaft 10 to mesh with each other.
