Description

Technical Field

[0001] This utility model belongs to the field of thermal insulation material testing technology, specifically a device for testing the thermal insulation performance of thermal insulation materials. Background Technology

[0002] After the insulation material is produced, its insulation performance is often tested to ensure that the design performance meets the standards. After the test, defective products can be rejected, thus avoiding rework costs caused by substandard performance.

[0003] A Chinese patent publication number, CN222838022U, discloses a device for testing the thermal insulation performance of thermal insulation materials. This device relates to the field of thermal insulation material performance testing equipment. The base has a heating wire and a support cone at its top, connecting ears on both sides, a sleeve shaft inside the connecting ears, a rotating rod at the top of the sleeve shaft, a fixing nut on the outside of the rotating rod, a limiting ear at the bottom of the fixing nut, a pressure cap on the other side of the limiting ear, a heat dissipation grid on the top of the pressure cap, a thermal insulation pad covering the surface of the heat dissipation grid, and a slot on the surface of the pressure cap. Heat is released through the heating wire at the top of the base, and the temperature generated by the heating wire is transferred to the interior of the thermal insulation material. If the thermal insulation material is insufficient, the temperature passes through the thermal insulation material to the other side. A temperature measuring probe located in the slot senses the temperature and displays it directly, allowing the operator to quickly observe and determine the current thermal insulation performance of the material. During the testing process, interference from the external environment is unlikely to affect the temperature measuring probe located inside the slot.

[0004] The aforementioned thermal insulation performance testing device, when clamping the thermal insulation material in the testing chamber, can only install materials of a specific size due to the spatial constraints between the heating element and the fixed area, requiring additional cutting, which affects work efficiency; therefore, a thermal insulation performance testing device for thermal insulation materials is proposed to address the above problems.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0018] Specific implementation examples are given below.

[0019] like Figure 1-5As shown, a thermal insulation performance testing device for thermal insulation materials includes a test chamber 1; multiple sets of fixing screws 11 are arranged on the outside of the test chamber 1; a closed top cover 12 is provided on the top of the test chamber 1; a test groove 13 is opened on the side wall of the closed top cover 12; a heating tube 14 is fixedly connected to the inside of the test chamber 1; multiple sets of connecting rods 15 are slidably connected to the side wall of the closed top cover 12; a limiting wheel 16 is rotatably connected to the end of the connecting rod 15; a threaded rod 17 is threadedly connected to the side wall of the end of the connecting rod 15; the end of the threaded rod 17 is located inside the limiting wheel 16; multiple sets of connecting curved plates 18 are slidably connected to the inside of the limiting wheel 16; an extrusion plate 19 is fixedly connected to one end of the multiple sets of connecting curved plates 18 close to each other; a connecting plate 110 is fixedly connected to both side walls of the extrusion plate 19; the side wall of the connecting plate 110 is connected to the inner side wall of the limiting wheel 16. During operation, when it is necessary to fix the insulation material, the insulation material can be made to fit against the inner top of the closed top cover 12. The operator can push multiple sets of connecting rods 15 into the closed top cover 12 and rotate the threaded rod 17 so that the other end of the threaded rod 17 enters the inner side of the limiting wheel 16, and simultaneously compresses multiple sets of extrusion plates 19, thereby causing multiple sets of connecting curved plates 18 to expand outward simultaneously. This allows the outer walls of multiple sets of connecting curved plates 18 to simultaneously compress and fix the insulation material. After the insulation material is fixed, the closed top cover 12 is sealed to the top of the test chamber 1 by the fixing screw 11. The operator can then install the measuring equipment. The device can directly detect the temperature of the space above the insulation material through the test slot 13. After the test is completed, the connecting rod 15 can be pulled outwards, and the multiple sets of connecting curved plates 18 will rotate accordingly, thereby releasing the fixing of the insulation material. When the threaded rod 17 is not pressing the extrusion plate 19, the multiple sets of connecting plates 110 can simultaneously drive the connecting curved plates 18 to reset. The entire device can push the connecting rod 15 according to the size of different insulation materials, so that the connecting curved plates 18 always press and fix the insulation material, thereby effectively improving the adaptability of the entire device to fixing insulation materials of different sizes and effectively improving work efficiency.

[0020] Furthermore, such as Figure 3 As shown, a sealing sleeve 2 is fixedly connected to the inner wall of the test groove 13; a connecting cylinder 21 is rotatably connected to the outermost end of the test groove 13; the sealing sleeve 2 and the connecting cylinder 21 are interconnected; multiple sets of ratchet teeth 22 are fixedly connected to the outer wall of the connecting cylinder 21; a second set of ratchet teeth 23 is rotatably connected to the side wall of the closed top cover 12; the second set of ratchet teeth 23 meshes with the first set of ratchet teeth 22; a locking block 24 is fixedly connected to the side wall of the closed top cover 12; the locking block 24 fits against the second set of ratchet teeth 23; a second connecting plate 25 is fixedly connected to the side wall of the second set of ratchet teeth 23; the side wall of the second connecting plate 25 is interconnected with the closed top cover 12. During operation, ratchet 22, ratchet 23, locking block 24 and connecting plate 25 cooperate with each other to restrict the rotation direction of the connecting drum 21. When the testing equipment enters the test tank 13 to test the internal space of the closed top cover 12, the connecting drum 21 can be rotated directly, causing the sealing sleeve 2 to deform and adhere tightly to the outside of the testing equipment, thereby reducing the possibility of external cold air entering the test tank 13 and causing a decrease in testing accuracy.

[0021] Furthermore, such as Figure 1 and Figure 3 As shown, the outer wall of the connecting cylinder 21 is provided with a toothed groove 3; multiple sets of toothed grooves 3 are provided on the outer side of the connecting cylinder 21; the side wall of the closed top cover 12 is rotatably connected to a connecting column 31; a toothed disc 32 is fixedly connected to the end of the connecting column 31; the toothed groove 3 and the toothed disc 32 mesh with each other. During operation, the operator can directly rotate the gear plate 32 through the connecting column 31, so that the gear groove 3 can directly drive the connecting rotating drum 21 to rotate; the overall device improves the ease of operation of the sealing sleeve 2 and effectively reduces the difficulty of operation.

[0022] Furthermore, such as Figure 3 As shown, the closed top cover 12 has a storage groove 4 on its side wall; a return spring 41 is fixedly connected to the side wall of the storage groove 4; the return spring 41 is connected to the toothed disc 32. When the operator rotates the gear plate 32, it can cause the return spring 41 to deform. The storage groove 4 and the return spring 41 cooperate with each other. When the operator operates the second ratchet 23 to no longer engage with the first ratchet 22, the deformed return spring 41 can drive the connecting rotating cylinder 21 to reset through the gear plate 32 and the tooth groove 3. This improves the ease of operation of the overall equipment.

[0023] Furthermore, such as Figure 4 As shown, each of the multiple sets of connecting rods 15 has a connecting ring 5 fixedly connected to its outer side wall; and a fixing post 51 is fixedly connected to the side wall of the connecting ring 5. During operation, the connecting ring 5 and the fixed column 51 cooperate with each other, and the operator can directly operate the fixed column 51 to achieve the effect of pushing multiple sets of connecting rods 15 to move synchronously, thereby improving the ease of operation of the overall equipment.

[0024] Furthermore, such as Figure 5 As shown, both sides of the extrusion plate 19 are fixed with extended curved plates 6; During operation, when the extrusion plate 19 extrudes the insulation material, the extension curved plate 6 assists in fixing the insulation material, thereby improving the stability of the insulation material when it is extruded and fixed inside the closed top cover 12.

[0025] Furthermore, such as Figure 5As shown, a ball bearing 7 is rotatably connected to one end of the threaded rod 17 near the extrusion plate 19; During operation, when the threaded rod 17 presses against the extrusion plate 19, the rotating ball 7 rotates accordingly. The rotating ball 7 can effectively reduce the friction between the side wall of the threaded rod 17 and the contact surface of the extrusion plate 19, and improve the stability of the threaded rod 17 and the extrusion plate 19 during long-term operation.

[0026] Working principle: During operation, when it is necessary to fix the insulation material, the insulation material can be made to fit against the inner top of the closed top cover 12. The operator can push multiple sets of connecting rods 15 into the closed top cover 12 and rotate the threaded rod 17, so that the other end of the threaded rod 17 enters the inner side of the limiting wheel 16 and simultaneously compresses multiple sets of extrusion plates 19, thereby causing multiple sets of connecting curved plates 18 to expand outward simultaneously. This allows the outer walls of multiple sets of connecting curved plates 18 to simultaneously compress and fix the insulation material. After the insulation material is fixed, the closed top cover 12 is sealed to the top of the test chamber 1 by the fixing screw 11. The operator can then use the measuring equipment to directly detect the temperature of the space above the insulation material through the test slot 13. After the test is completed... After completion, the connecting rod 15 can be pulled out directly, and the multiple sets of connecting curved plates 18 will rotate accordingly, thus releasing the fixing work on the insulation material; when the threaded rod 17 is not pressing the extrusion plate 19, the multiple sets of connecting plates 110 can simultaneously drive the connecting curved plates 18 to reset; the entire device can push the connecting rod 15 according to the size of different insulation materials, so that the connecting curved plates 18 always press and fix the insulation material, thereby effectively improving the adaptability of the entire device to fixing insulation materials of different sizes, and effectively improving work efficiency; the ratchet 1 22, ratchet 23, and locking block 24 cooperate with the connecting plate 25 to limit the rotation direction of the connecting drum 21; when the testing equipment enters the inner side of the test tank 13, the top cover is closed. When testing the internal space of 12, the connecting drum 21 can be rotated directly, causing the sealing sleeve 2 to deform and adhere tightly to the outside of the testing equipment, thereby reducing the possibility of external cold air entering the test tank 13 and causing a decrease in testing accuracy. The operator can directly rotate the gear plate 32 through the connecting column 31, so that the tooth groove 3 can directly drive the connecting drum 21 to rotate. The overall device improves the ease of operation of the sealing sleeve 2 and effectively reduces the difficulty of operation. When the operator rotates the gear plate 32, it can drive the return spring 41 to deform, and the placement slot 4 and the return spring 41 cooperate with each other. When the operator operates the second ratchet 23 to no longer engage with the first ratchet 22, the deformed return spring 41 can pass through the gear plate 32 and the tooth groove. 3. The connecting drum 21 is reset, thereby improving the ease of operation of the overall equipment; the connecting ring 5 and the fixed column 51 cooperate with each other, and the operator can directly operate the fixed column 51 to achieve the effect of pushing multiple sets of connecting rods 15 to move synchronously, thereby improving the ease of operation of the overall equipment; when the extrusion plate 19 extrudes the insulation material, the extension curved plate 6 assists in fixing the insulation material, thereby improving the stability of the insulation material when it is extruded and fixed inside the closed top cover 12; when the threaded rod 17 extrudes the extrusion plate 19, the rotating ball 7 rotates with it, and the rotating ball 7 can effectively reduce the friction between the side wall of the threaded rod 17 and the contact surface of the extrusion plate 19, and improve the stability of the threaded rod 17 and the extrusion plate 19 during long-term operation.
