[0023] See also Figure 1 The surface of the movable plate 4 is threadedly connected with a tightening bolt 3, one end of which is in close contact with the surface of the fixed block 6. By setting the tightening bolt 3, it can be tightened with the fixed block 6 in the screwed-in state to prevent the movable plate 4 from rotating at will;

[0024] See also Figure 3 There are two movable rods 203, both of which are movably connected to the inner wall of the fixed frame 1, and a driving motor 201 is bolted to the back surface of the fixed frame 1;

[0025] See also Figure 3 The output end of the driving motor 201 is fixedly connected to the connection of the movable rod 203, and the two gears 202 are meshed. By setting the gears 202, the two gears 202 can cooperate to play a role of meshing transmission. Under the drive of the driving motor 201, the two rotating blocks 204 can be rotated outward or inward at the same time;

[0026] See also Figure 3 , a connecting sleeve 206 is fixedly connected to the top of the rotating block 204, and a sliding rod 205 is slidably installed in the inner cavity of the connecting sleeve 206;

[0027] See also Figure 3A mounting seat 208 is provided on the top of the fixed frame 1, a protrusion 207 is fixedly connected to the front surface of the mounting seat 208, and the surface of the slide bar 205 is movably connected to the connection between the protrusion 207 and the surface of the slide bar 205. By providing the slide bar 205, the connecting sleeve 206 and the protrusion 207, the connection state can be ensured when the rotating block 204 rotates forward and backward, so that the mounting seat 208 synchronously produces left and right displacement;

[0028] See also Figure 3 and Figure 4 , an electric push rod 209 is bolted at the top center of the mounting seat 208. By setting the electric push rod 209, the displacement plate 702 can be pressed in the extended state. The fixed plate 701 is located in the mounting seat 208. The surfaces of the fixed plate 701 and the mounting seat 208 are fixedly inlaid with magnetic blocks 706. By setting the magnetic blocks 706, when the fixed plate 701 is installed, the magnetic blocks 706 on the mounting seat 208 can contact and magnetically attract the magnetic blocks 706 on the fixed plate 701, thereby improving the installation stability of the fixed plate 701;

[0029] See also Figure 3 and Figure 4 A guide rod 703 is fixedly connected to the rear side of the top of the fixed plate 701, and a guide hole 704 used in conjunction with the guide rod 703 is provided on the surface of the displacement plate 702. By providing the guide rod 703 and the guide hole 704, the displacement of the displacement plate 702 can be guided to ensure the stability of the up and down movement of the displacement plate 702;

[0030] See also Figure 3 and Figure 4 A positioning rod 707 is fixedly connected to the front surface of the fixed plate 701, and a spring 705 is fixedly connected to the front side of the top of the displacement plate 702. The other end of the spring 705 is fixedly connected to the surface of the fixed plate 701. By setting the spring 705, the displacement plate 702 can be elastically connected, and the displacement plate 702 can be kept at a high position above the fixed plate 701 without external force.

[0031] The bottom of the mounting seat 208 is fixedly connected with a T-block used in conjunction with the T-slot 5. The T-block and the T-slot 5 can ensure the left-right sliding stability of the mounting seat 208.

[0032] The surface of the displacement plate 702 is in sliding contact with the connection of the fixed plate 701;

[0033] A concave hole for use with the positioning rod 707 is formed through the front side of the mounting seat 208 . The positioning rod 707 cooperates with the concave hole to quickly and accurately mount the fixing plate 701 on the mounting seat 208 .

[0034] When in use, all components are in the initial installation state. When it is necessary to perform a fracture tensile test on the tape, first move the fixed plate 701. Under the cooperation of the positioning rod 707 and the concave hole, the fixed plate 701 is quickly and accurately docked with the mounting seat 208. The two magnetic blocks 706 magnetically attract to ensure the installation stability of the fixed plate 701. First, control the electric push rod 209 to extend and press the displacement plate 702. The spring 705 is stretched. With the assistance of the guide rod 703 and the guide hole 704, the displacement plate 702 is stably moved down and cooperates with the fixed plate 701 to clamp the tape. Then control the drive motor 201 to work. Under the meshing transmission of the gear 202, the two movable rods 203 rotate outward in opposite directions, and the rotating block 204 rotates synchronously. 06. With the cooperation of the slide bar 205 and the protrusion 207, the two mounting seats 208 are displaced outward at the same time to achieve the purpose of tensile testing of the clamped tape. In actual application, when the tape needs to be subjected to a long-distance tensile test, the movable plate 4 is rotated to a horizontal state, and the tightening bolts 3 are screwed in to tighten with the fixed block 6 to ensure the stability of the position of the movable plate 4. At this time, during the stretching process, the mounting seat 208 is displaced and placed above the movable plate 4 to extend the overall stretching distance; after long-term use, the glue on the surface of the tape remains on the fixed plate 701 and the displacement plate 702. The staff can replace the detachable clamping assembly 7 to meet the normal fracture tensile test requirements, and then use the degumming liquid to centrally degumming multiple detachable clamping assemblies 7.

[0035] To sum up: the fracture stretching device for detecting waterproof foam tape solves the problem that the fracture stretching device does not have the function of folding and storing by arranging a displacement stretching component 2, a tightening bolt 3, a movable plate 4, a T-slot 5, a fixing block 6 and a detachable clamping component 7. Its overall length is relatively large. When used in the actual testing process, it often requires a larger installation and use space, which has certain restrictions.
