Figure 1 , including a test machine body 1, a positioning member 2 installed on a fixture of the test machine body 1, and a positioning fixture 3 installed on the positioning member 2 and used to clamp and position the thermal insulation strip. The positioning member 2 includes a stabilizing block 21 clamped by the fixture of the test machine body 1 and a connecting screw 22 installed on the fixture of the test machine body 1. The stabilizing block 21 is trapezoidal in the embodiment of the present application, which is convenient for clamping by the fixture and improves the stability of the initial state of the positioning fixture 3. The stabilizing block 21 is provided with a through groove 8 along the height direction, and the through groove 8 is used for the connecting screw 22 to pass through the stabilizing block 21 and connect with the fixture. A positioning seat 9 threadedly connected to the end of the connecting screw 22 is fixedly installed on the test machine body 1. The positioning seat 9 of the present application is installed on the fixture of the test machine body 1. A protrusion 10 is fixedly installed on the outer wall of the positioning seat 9. A groove 11 for positioning the protrusion 10 is provided on the stabilizing block 21. The protrusion 10 and the groove 11 improve the connection strength between the positioning seat 9 and the stabilizing block 21, thereby further improving the stability of the positioning fixture 3.

[0028] Reference Figure 1 and Figure 2The positioning fixture 3 includes a connecting block 31 installed on the positioning member 2, positioning clamps 32 installed on both sides of the length direction of the connecting block 31, and a control member 33 for controlling the two positioning clamps 32 to approach each other. The connecting block 31 includes a fixing portion 311 installed at one end of the connecting screw 22, a tapered portion 312 installed on the fixing portion 311, and a pressing portion 313 installed at the end of the tapered portion 312 away from the fixing portion 311. A threaded hole is provided at the bottom of the fixing portion 311 to facilitate the connection between the fixing portion 311 and the connecting screw 22. The width of the tapered portion 312 gradually decreases away from the fixing portion to adapt to the width of the thermal insulation strip, so that the pressing portion 313 can position one side of the thermal insulation strip. In the embodiment of the present application, the fixing portion 311, the tapered portion 312 and the pressing portion 313 are integrally formed to improve the strength of the connecting block 31.

[0029] Reference Figure 1 and Figure 2 The clamping surface of the positioning clamp block 32 extends along the shape of the side wall of the connecting block 31, thereby improving the adaptability of the positioning clamp block 32 to the thermal insulation strip. A fixing groove 4 is formed between the clamping end of the positioning clamp block 32 and the pressing portion 313. The shape of the fixing groove 4 is consistent with the shape of the clamping end of the thermal insulation strip, thereby improving the clamping and positioning effect of the positioning clamp block 32 on the thermal insulation strip.

[0030] Reference Figure 2 , the connection block 31 is provided with a positioning groove 6, and the positioning clamp block 32 is fixedly installed with a positioning block 7. In the present application, the positioning block 7 is integrally formed with the positioning clamp block 32. The control member 33 is used to control the positioning clamp blocks 32 on both sides to clamp the ends of the heat insulation strip. In the present application, the control member 33 uses an adjusting bolt. The connection block 31 is provided with a through hole 1 for the control member 33 to pass through along the width direction. Among the two positioning clamp blocks 32, one of the positioning clamp blocks 32 is provided with a through hole 2 connected to the through hole 1; the other positioning clamp block 32 is provided with a threaded hole connected to the through hole 1. After one end of the control member 33 passes through the through hole 1 and the through hole 2, it is screwed and positioned with the positioning clamp block 32 through the threaded hole, so that the control member 33 can control the two positioning clamp blocks 32 to approach each other.

[0031] The implementation principle of a thermal insulation strip testing device in an embodiment of the present application is: insert the two ends of the thermal insulation strip into a fixing groove 4, and then turn the control part 33 to allow the positioning clamps 32 on both sides to clamp and position the thermal insulation strip. The present application improves the clamping and positioning effect of the device on the thermal insulation strip through the positioning clamp 3, thereby improving the stability of the thermal insulation strip during testing.
