Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation material detection, and particularly relates to a detection device for the heat insulation performance of building thermal insulation materials. Background Technique

[0002] Thermal insulation materials generally refer to materials with a thermal coefficient less than or equal to 0.12. The development of thermal insulation materials is very fast. Adopting good thermal insulation technologies and materials in industry and construction can often achieve twice the result with half the effort. For every ton of mineral wool thermal insulation products used in buildings, and during the building construction process, it is necessary to conduct heat insulation detection on thermal insulation materials to know whether the materials used meet the specified standards, which requires the use of detection devices for detection operations.

[0003] When the detection device detects thermal insulation materials, it can only detect one thermal insulation material at a time, and its detection efficiency is low. Moreover, when detecting materials with different widths, gaps will appear at the original detection positions due to different material sizes, which will affect the detection. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a detection device for the heat insulation performance of building thermal insulation materials, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A detection device for the heat insulation performance of building thermal insulation materials includes a base and a heating device. The heating device is fixedly installed in the middle of the upper surface of the base. Moving plates are movably installed on the upper surface of the base near both sides. Limiting plates are movably installed on the upper surface of the moving plates near both sides. Closing plates are movably installed on the front and rear sides of the two side surfaces of the heating device. Lever plates are movably installed on one side of the closing plates on both sides of the heating device.

[0007] Preferably, a knob is movably installed on one side surface of the moving plate. A double-headed threaded rod is fixedly installed on the rear surface of the knob. One end of the double-headed threaded rod extends into the inside of the moving plate. A threaded sleeve block is fixedly installed on the lower surface of the moving plate. The threaded sleeve block is sleeved on the surface of the double-headed threaded shaft.

[0008] Preferably, moving grooves are opened on the front and rear sides near the two side surfaces of the heating device. Guide rods are fixedly installed inside the moving grooves. Springs are sleeved on the surfaces of the guide rods. Heating strips are fixedly installed inside the heating device.

[0009] Preferably, a groove is provided on one side surface of the closing plate near the rear, and a sliding sleeve is fixedly installed on the other side surface of the closing plate at the rear, the sliding sleeve is sleeved on the surface of the guide rod, one end of the spring is fixed to the sliding sleeve, and the other end of the spring is fixed to an inner end surface of the movable groove.

[0010] Preferably, a baffle is fixedly installed on one side surface of the limit plate and located in the front, a pressure plate is movably embedded in the rear surface of one side of the limit plate, a limiting groove is provided on the front surface of the limit plate, a threaded sleeve is fixedly installed on the lower surface of the limit plate, and the threaded sleeve is arranged on the surface of the double-headed threaded rod.

[0011] Preferably, a support rod is fixedly installed on one side surface of the seesaw, and a flip axis is fixedly installed on the upper and lower surfaces of the support rod. A torsion spring is sleeved on the surface of the flip axis, one end of the torsion spring is fixed to the heating device, and the other end of the torsion spring is fixed to the support rod, and the rear end of the seesaw is embedded in the groove.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, by arranging the heating device, the limit plate, the seesaw plate and the closing plate in a manner that cooperate with each other, when it is necessary to test the thermal insulation performance of thermal insulation materials of different widths, the pressure plate of the limit plate is pulled to a position where it can press the seesaw plate. When the movable plate moves to a certain position, the pressure plate will press the seesaw plate, so that the rear end of the seesaw plate tilts up from the groove of the closing plate. At this time, the closing plate moves toward the inside of the heating device under the tension of the spring until the closing plate is blocked by the baffle. At this time, the thermal insulation material between the limit plates and the limit plates block both sides of the heating device, thus avoiding heat dissipation, thereby ensuring the accuracy of the detection. In addition, two thermal insulation materials can be tested simultaneously during the detection process, thereby improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] As Figures 1-5 shown, a detection device for the heat insulation performance of a building thermal insulation material includes a base 1 and a heating device 2. The heating device 2 is fixedly installed on the upper surface of the base 1 and in the middle. The moving plates 3 are movably installed on the upper surface of the base 1 and near both sides. The limiting plates 4 are movably installed on the upper surface of the moving plates 3 and near both sides. The closing plates 6 are movably installed on the front and rear sides of the two side surfaces of the heating device 2. The seesaws 5 are movably installed on one side of the two sides of the heating device 2 and on one side of the closing plates 6. The rotating motor 7 is fixedly installed on one side surface of the base 1. The output end of the rotating motor 7 is fixedly installed with a double-headed threaded shaft 8.

[0022] On one side surface of the moving plate 3, a knob 301 is movably installed. On the rear surface of the knob 301, a double-headed threaded rod 303 is fixedly installed. One end of the double-headed threaded rod 303 extends into the interior of the moving plate 3. On the lower surface of the moving plate 3, a threaded sleeve block 302 is fixedly installed. The threaded sleeve block 302 is sleeved on the surface of the double-headed threaded shaft 8. The rotating double-headed threaded shaft 8 can control the moving plates 3 to approach and move away from each other; on both side surfaces of the heating device 2 and near the front and rear, moving grooves 202 are opened. Inside the moving grooves 202, guide rods 203 are fixedly installed. On the surface of the guide rods 203, springs 204 are sleeved. Inside the heating device 2, heating strips 201 are fixedly installed. The spring 204 has a pulling force on the sliding sleeve 601 to approach the interior of the heating device 2; on one side surface of the closing plate 6 and near the rear, a groove 602 is opened. On the other side surface of the closing plate 6 and at the rear, a sliding sleeve 601 is fixedly installed. The sliding sleeve 601 is sleeved on the surface of the guide rod 203. One end of the spring 204 is fixed to the sliding sleeve 601, and the other end of the spring 204 is fixed to one end surface of the interior of the moving groove 202; on one side surface of the limiting plate 4 and at the front, a baffle 401 is fixedly installed. On the rear surface of one side of the limiting plate 4, a pressing plate 404 is movably embedded. On the front surface of the limiting plate 4, a limiting groove 402 is opened. On the lower surface of the limiting plate 4, a threaded sleeve 403 is fixedly installed. The threaded sleeve 403 is sleeved on the surface of the double-headed threaded rod 303; on one side surface of the rocker 5, a support rod 501 is fixedly installed. On the upper surface and the lower surface of the support rod 501, rotating shafts 502 are fixedly installed. On the surface of the rotating shafts 502, torsion springs 503 are sleeved. One end of the torsion spring 503 is fixed to the heating device 2, and the other end of the torsion spring 503 is fixed to the support rod 501. The rear end of the rocker 5 is embedded in the groove 602. The rocker 5 can position the closing plate 6 when not in use.

[0023] It should be noted that the present utility model is a device for detecting the heat insulation performance of building thermal insulation materials. When in use, when it is necessary to detect the heat insulation performance of thermal insulation materials with different widths, rotate the knob 301 to move the two limiting plates 4 to the required positions, and then pull the pressing plate 404 of the limiting plate 4 to a position where it can press the rocker 5. At this time, the rotating motor 7 drives the double-headed threaded shaft 8 to rotate under the control of an external device, so that the two moving plates 3 approach each other. When the moving plates 3 move a certain position, the pressing plate 404 will press the rocker 5, causing the rear end of the rocker 5 to lift from the groove 602 of the closing plate 6. At this time, the closing plate 6 moves towards the interior of the heating device 2 under the pulling force of the spring 204 until the closing plate 6 is blocked by the baffle 401. At this time, the thermal insulation material between the limiting plates 4 and the limiting plates 4 block both sides of the heating device 2, thus avoiding heat dissipation and ensuring the accuracy of the detection. And during the detection process, two thermal insulation materials can be detected simultaneously, improving the work efficiency.
