DETAILED DESCRIPTION

[0018] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0019] like Figure 1-6 As shown, a PVC film thermal insulation performance testing device comprises a box body 1, a simulation lamp 2 is arranged at the upper end of the box body 1, a thermal insulation rate detector 5 is arranged at the lower end of the box body 1, a through groove 6 is opened in the middle of the box body 1, and fixed rails 7 are arranged on both sides of the through groove 6, and a fixing clamp 8 is also included. The fixing clamp 8 can slide in the fixed rail 7, and a PVC film 9 is clamped on the fixing clamp 8. A feeding box 10 and a receiving box 11 are respectively arranged on both sides of the box body 1, and a connecting groove that penetrates the through groove 6 is opened on one side of the bottom of the feeding box 10 and the receiving box 11. The upper ends of the feeding box 10 and the receiving box 11 are both open, and the side of the feeding box 10 away from the box body 1 is opposite to the feeding box 10. It is said that it is provided with a sliding groove and also includes a push-pull rod 12 that can slide on the outer surface of the box body 1, a hook rod 13 is provided at one end of the push-pull rod 12, a support block 14 is provided on the side of the hook rod 13 away from the box body 1, and an arc block 15 is provided at the other end of the push-pull rod 12. A through hole is provided inside the material receiving box 11, and a mounting plate 16 that matches the arc block 15 is provided at the outer bottom of the material receiving box 11. A support rod 17 that can slide in the through hole is provided on the upper surface of the mounting plate 16. A spring 18 is sleeved on the support rod 17, and the spring 18 is located between the mounting plate 16 and the bottom of the material receiving box 11, and the two ends of the spring 18 are fixedly connected to the mounting plate 16 and the material receiving box 11 respectively.

[0020] The outer surface of the box 1 is coated with insulation material, and the box 1 is in an opaque state to reduce the impact of external temperature on the thermal insulation performance of the PVC film 9. The simulation lamp 2 is an infrared lamp used to simulate a heat source. The distance between the simulation lamp 2 and the thermal insulation rate detector 5 is always kept the same to improve the accurate detection of PVC films 9 with different formulas. A screen 4 is also provided on the outer surface of the box 1 to display the experimental data of the thermal insulation rate detector 5.

[0021] The fixing clip 8 is divided into two parts, the upper and lower parts can be buckled together to clamp the PVC film 9 in the middle of the fixing clip 8, and when the fixing clip 8 is completely placed in the through groove 6, the outer surfaces of both ends of the fixing clip 8 are respectively in the same plane with the outer surfaces of both sides of the box body 1.

[0022] The interior of the feeding box 10 is used to place the fixing clip 8 with the PVC film 9. The size of the feeding box 10 is roughly equal to that of the fixing clip 8 to reduce the shaking of the fixing clip 8 in the feeding box 10, so as to facilitate the stable pushing of the fixing clip 8 in the feeding box 10 through the through slot 6 into the fixing rail 7 of the box body 1, and the fixing clip 8 in the feeding box 10 leaves the feeding box 10 from the bottom of the feeding box 10; when the fixing clip 8 in the feeding box 10 needs to enter the box body 1, the fixing clip 8 in the feeding box 10 is pushed into the box body 1 by moving the push-pull rod 12 and then the hook rod 13 on the push-pull rod 12 1, the fixing clip 8 originally existing in the box body 1 passes through the through slot 6 and enters the material receiving box 11. When the fixing clip 8 begins to exist in the material receiving box 11, the fixing clip 8 will affect the fixing clip 8 in the subsequent box body 1 to enter the material receiving box 11. Therefore, by setting the support rod 17, the end of the fixing clip 8 close to the through slot 6 can be tilted, and the tilted height of one end of the fixing clip 8 is greater than the thickness of the fixing clip 8, so that the fixing clip 8 that comes in later can enter under the previous fixing clip 8. Specifically, when the push-pull rod 12 moves, the arc block 15 moves with the push-pull rod 12. , and the mounting plate 16 will not move with the push-pull rod 12. When the mounting plate 16 lacks the support of the arc block 15, the mounting plate 16 is pushed downward under the reaction of the spring 18. After being pushed by the spring 18, the height of the lower end of the mounting plate 16 is still higher than the lower surface of the arc block 15, so that the arc block 15 continues to enter under the mounting plate 16. After the mounting plate 16 moves downward under the thrust of the spring 18, the upper end of the support rod 17 moves downward from the material receiving box 11, so that the inner bottom of the material receiving box 11 is not blocked, which is convenient for pushing the fixing clip 8 in the box body 1 into the material receiving box 11. Then, the push-pull rod 12 is pushed in the opposite direction, and the push-pull rod 12 drives the arc block 15 to move, and the arc block 15 re-enters under the mounting plate 16, and compresses the spring 18, so that the upper end of the support rod 17 re-enters the material receiving box 11, and the support rod 17 lifts the end of the fixing clamp 8 located above, which is close to the box body 1, so as to realize the conveying of the fixing clamp 8 from the bottom of the material receiving box 11 to the material receiving box 11. Since the fixing clamp 8 needs to be tilted in the material receiving box 11, the length of the material receiving box 11 is slightly longer than the fixing clamp 8, so that the fixing clamp 8 can rise and fall in a small range in the material receiving box 11.

[0023] And when the push-pull rod 12 pushes the fixed clip 8 in the feeding box 10 through the hook rod 13, in order to prevent the fixed clip 8 located above the feeding box 10 from hindering the reset of the push-pull rod 12, a support block 14 is set up so that the subsequent fixed clip 8 can fall onto the support block 14, so that the push-pull rod 12 can move freely in the feeding box 10.

[0024] Furthermore, a slot 19 is provided at the lower end of the material receiving box 11 , and the push-pull rod 12 can move horizontally in the slot 19 . The slot 19 is used to improve the stability of the movement of the push-pull rod 12 .

[0025] Furthermore, the outer surfaces of the feeding box 10 and the receiving box 11 are symmetrically provided with notches 20, through which it is convenient to put the fixing clip 8 into the feeding box 10, and it is also convenient to take out the fixing clip 8 and PVC film 9 after the experiment from the receiving box 11.

[0026] Furthermore, a support foot 21 is provided at the lower end of the box body 1 , and an anti-slip member 22 is provided at the bottom of the support foot 21 . The anti-slip member 22 may be a rubber gasket or a suction cup, which is used to increase the friction with the work surface and reduce the shaking of the box body 1 .

[0027] Furthermore, a limit block 3 is provided on one side of the push-pull rod 12 , and the limit block 3 facilitates rapid and accurate resetting of the push-pull rod 12 .

[0028] Working principle: After the PVC film 9 on the fixing clip 8 in the box body 1 has completed the experiment, the push-pull rod 12 is quickly moved, and the fixing clip 8 at the bottom in the feeding box 10 is pushed into the fixed rail 7 in the box body 1 through the hook rod 13, and the fixing clip 8 originally located in the box body 1 is squeezed and moved into the receiving box 11. After the pushing of the fixing clip 8 in the box body 1 is completed, the push-pull rod 12 is controlled to move in the opposite direction, and through the cooperation of the arc block 15 and the mounting plate 16, the support rod 17 on the mounting plate 16 lifts one end of the fixing clip 8, so that the subsequent fixing clip 8 can enter the receiving box 11 from the bottom of the receiving box 11.

[0029] The device can push the fixing clip 8 and the PVC film 9 in the feeding box 10 into the box body 1 by controlling the pulling and pushing actions of the push-pull rod 12, and push the fixing clip 8 already in the box body 1 into the receiving box 11. The fixing clip 8 enters from the bottom of the receiving box 11, which can improve the storage stability of the fixing clip 8 in the receiving box 11 and prevent it from colliding. The PVC film 9 sample can be replaced quickly and conveniently, and the detection efficiency is significantly improved.
