[0002] Thermally insulated aluminum alloy profiles (commonly known as "broken bridge aluminum") are based on ordinary aluminum alloy profiles, with PA66 nylon thermal insulation strips or polyurethane foam materials added to disconnect the inner and outer aluminum profiles, forming a "cold and hot bridge" structure that blocks heat conduction.34 This structure reduces the heat transfer coefficient of the profile to below 0.96 W / (m²·K), improving thermal insulation performance by more than 60% compared to ordinary aluminum alloys.710 According to GB / T 28289-2012 standard, its shear strength is a core quality indicator, and the reliability of the interface bonding between the thermal insulation layer and the metal profile must be verified through longitudinal shear tests.

The contact testing mechanism 8 includes a pressure sensor 22, and a contact plate 23 is fixedly connected to the lower end of the pressure sensor 22. The pressure sensor 22 is electrically connected to the test data display 5. During the test, the pressure sensor 22 is used to detect the force between the aluminum alloy profile to be tested and the contact testing mechanism 8, and the test data is displayed on the test data display 5.

The rear end of the clamping screw 26 passes through the front wall of the clamping adjustment frame 24 and the two limiting blocks 25 in sequence and is rotatably connected to the rear inner wall of the clamping adjustment frame 24. The clamping screw 26 is a bidirectional screw. The thread direction of the connection between the two limiting blocks 25 and the clamping screw 26 is opposite.

At the same time, the setting of the abutting spring 18 above the sliding plate 19 ensures that when the device detects multiple aluminum alloy profiles, all of them can receive sufficient detection pressure.

[0019] Both limit blocks 25 have clamping grooves 33 on their adjacent side walls, with the upper end of the clamping grooves 33 being open. When testing the longitudinal shear strength of the aluminum alloy profile to be tested, the sample to be tested is placed in the clamping grooves 33, and the clamping screw 26 is rotated by rotating the clamping knob 27, which in turn causes the two limit blocks 25 to move closer to each other and clamp and fix the aluminum alloy profile to be tested.

[0020] Two clamping grooves 33, located away from each other on their sidewalls, each have a placement hole 32. The lower inner wall of the placement hole 32 is located above the lower inner wall of the clamping groove 33. The lower inner wall of the placement hole 32 is located above the upper end faces of the front and rear side walls of the clamping adjustment frame 24. The front end of the front limiting block 25 is fixedly connected to an upper fixing plate 29 and a lower support plate 30.

When it is necessary to test the transverse shear strength of the aluminum alloy profile to be tested, the shear strength tester passes through the two placement holes 32 and tightens the screw 31. The screw 31 is used to clamp and fix the shear strength tester. Then, the lifting plate 6 is pushed down by the testing cylinder 4, and the aluminum alloy profile to be tested is tested by the contact testing mechanism 8.

[0021] A protective window 10 is provided inside the support frame 1. The protective window 10 is L-shaped, and its longitudinal sidewall is made of transparent material. A lifting motor 13 and two limiting slide rods 15 are fixedly connected to the lower inner wall of the support frame 1. The upper end of the limiting slide rods 15 passes through the transverse sidewall of the protective window 10 and is fixedly connected to the upper inner wall of the support frame 1. The limiting slide rods 15 are slidably connected to the transverse sidewall of the protective window 10. A lifting screw 14 is fixedly connected to the output end of the lifting motor 13. The upper end of the lifting screw 14 passes through the transverse sidewall of the protective window 10 and is rotatably connected to the upper inner wall of the support frame 1. The lifting screw 14 is threadedly connected to the transverse sidewall of the protective window 10. One side of the upper end of the longitudinal sidewall of the protective window 10 passes through the upper sidewall of the support frame 1 and the lower sidewall of the detection frame 2 and extends to the inside of the operation window 3. During detection, the lifting motor 13 drives the lifting screw 14 to rotate. With the cooperation of the lifting screw 14 and the protective window 10, the protective window 10 moves up and down, thereby completing the closing and opening of the operation window 3. Both the lower side wall of the test frame 2 and the upper side wall of the support frame 1 are provided with through holes 12. The through holes 12 are located in front of the clamping and fixing mechanism 9. A protective plate 16 is fixedly connected to the upper end of the transverse side wall of the protective window 10. The upper end of the protective plate 16 passes through the two through holes 12 and extends to the inside of the test frame 2. The protective plate 16 is used to shield the aluminum alloy profile to be tested during the test process, further ensuring the safety of the test personnel. A reflector 11 is provided on the inner side of the detection frame 2. The left and right ends of the reflector 11 are fixedly connected to the inner walls of the left and right sides of the detection frame 2, respectively. The upper end of the reflector 11 is tilted to the rear. The reflector 11 is used to facilitate the operator to observe the detection status of the aluminum alloy profile to be tested on the rear side of the protective plate 16.

[0022] Working principle: During use, the clamping lifting motor 13 drives the lifting screw 14 to rotate, moving the protective window 10 into the support frame 1. The operating window 3 is then opened, and the clamping fixing mechanism 9 is used to fix the position of the aluminum alloy profile to be tested. When testing the longitudinal shear strength of the aluminum alloy profile, the sample to be tested is placed in the clamping groove 33, and the clamping knob 27 is rotated to drive the clamping screw 26 to rotate, thereby driving the two limit blocks 25 to move closer together to clamp and fix the aluminum alloy profile to be tested. The lifting motor 13 and the lifting screw 14 work together to move the protective window 10 into the support frame 1. The lifting plate 6 moves upward, using the protective window 10 to close the operating window 3. Simultaneously, the protective plate 16 extends to the front of the clamping and fixing mechanism 9, forming a protective wall structure. Then, the detection cylinder 4 pushes the lifting plate 6 downward, using the abutment detection mechanism 8 to detect the aluminum alloy profile to be tested. During testing, the lower end of the abutment plate 23 abuts against the upper end of the aluminum alloy profile to be tested. As the detection cylinder 4 pushes the lifting plate 6 downward, the pressure detection sensor 22 detects the force between the aluminum alloy profile to be tested and the abutment detection mechanism 8, and the detection data is displayed on the detection data display 5. When it is necessary to test the transverse shear strength of the aluminum alloy profile to be tested, the shear strength tester passes through the two placement holes 32 and tightens the fixing screw 31. The fixing screw 31 clamps and fixes the shear strength tester. Then, the detection cylinder 4 pushes the lifting plate 6 downward, using the abutment detection mechanism 8 to test the aluminum alloy profile to be tested. The detection data is displayed on the detection data display 5.
