[0025] Please refer again Figure 1 、 Figure 2 and Figure 3 The fixing mechanism includes a mounting frame 4 fixed to the top of the base 1 and mounted on the bottom of the lifting plate 3.

The splint 64 is pushed to slide into the interior of the through slot 51 by the extrusion of the extrusion rod 63, and the sealing strip is clamped and fixed by the splint 64 and the inner wall of the through slot 51.

[0026] Please refer again Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5The two ends of the rotating cylinder 5 are fixedly connected to the rotating rod 52, and the rotating cylinder 5 is rotatably connected to the inside of the mounting frame 4 through the two rotating rods 52. The rotating cylinder 5 is rotated inside the mounting frame 4 by the rotating rod 52. The mounting frame 4 is provided with a limiting mechanism that limits the rotation of the rotating cylinder 5. The limiting mechanism includes a side box 7 fixed on the mounting frame 4, one end of a rotating rod 52 extends to the inside of the side box 7, and the rotating rod 52 is fixedly connected to the rotating disk 71. The outer surface of the rotating disk 71 is provided with a circumferential array of slots 72. The side box 7 is fixedly connected to the connecting box 8, and the interior of the connecting box 8 is slidably connected with a pull rod 81, and one end of the pull rod 81 is fixedly connected to the plug block 82. One end of the plug block 82 is inserted into the inside of the slot 72. By inserting one end of the plug block 82 into the inside of the slot 72, the rotating disk 71 is restricted from rotating inside the side box 7, thereby limiting the rotation of the rotating cylinder 5 inside the mounting frame 4.

A tension sensor 9 is inlaid on the top of the lifting plate 3, and the detection end of the tension sensor 9 is fixedly connected to a mounting bracket 4. The tension sensor 9 is used to understand the size of the tension on the seal, and the tension sensor 9 and the driving motor 23 are electrically connected to the controller 10, which is convenient for controlling it through the provided controller 10.

[0029] Working principle: Install the device in a suitable position and connect it to the municipal power supply. The two ends of the sealing strip to be tested are respectively inserted into the two through slots 51. By driving the turntable at one end of the bidirectional screw 61, the two sliding blocks 62 are made to slide close to each other. Under the extrusion action of the extrusion rod 63, the splint 64 is pushed close to the sealing strip inside the through slot 51. The sealing strip is clamped and fixed by the splint 64 and the through slot 51. Finally, the handwheel at one end of the rotating rod 52 is driven to drive the rotating drum 5 to rotate inside the mounting frame 4. The sealing strip is wound by the rotating drum 5. When the plane of the insert block 82 is tightly pressed against the plane of the slot 72, the reverse rotation of the rotating disk 71 is restricted, so that the rotating rod 52 forms a one-way rotation, so that one end of the sealing strip is stably wound on the rotating drum 5. By starting the drive motor 23 to drive the adjusting screw 21 to rotate, the lifting plate 3 is raised between the two slideways 2 to test the tensile strength of the sealing strip.
