Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a waterproof coiled material puncture resistance testing device. Background Art

[0002] Waterproof membranes are mainly used in building walls, roofs, tunnels, roads, landfills, etc. They are a kind of flexible building material product that can be rolled into a roll to prevent the leakage of external rainwater and groundwater. As a leak-proof connection between the project foundation and the building, it is the first barrier to waterproofing the entire project and plays a vital role in the entire project. Before being put into use, the waterproof membrane needs to be tested with testing equipment for its puncture resistance.

[0003] However, the existing testing equipment requires the waterproof membrane to be fixed on the top of the test bench during testing. The method of squeezing and fixing by means of a pressure plate and bolts is cumbersome in operation, which increases the time required for replacing the membrane and thus reduces the detection efficiency of the equipment. Therefore, a waterproof membrane puncture resistance testing device is proposed. Utility Model Content

[0029] Reference Figures 1 to 6The utility model provides a puncture resistance testing device for waterproof coiled materials: it includes a chassis 1, an interactive terminal 2 is provided on the front of the chassis 1, a test chamber 3 is provided in the chassis 1, a chamber door 4 is provided on the front of the chassis 1, a puncture push rod 5 is fixedly provided on the top inner wall of the test chamber 3, and a puncture needle 6 is fixedly provided on the output end of the puncture push rod 5, a test seat 7 is fixedly provided on the bottom inner wall of the test chamber 3, a groove 8 is provided on the top of the test seat 7, a pressure plate 12 is movably provided on the top of the test seat 7, a plurality of circular holes 9 are provided on the top of the test seat 7, a first spring 10 is fixed in each of the plurality of circular holes 9, a plurality of sliding rods 11 are fixedly provided on the bottom of the pressure plate 12, the bottom of the sliding rod 11 is fixedly connected to the first spring 10, and the sliding rod 11 is slidably connected to the circular hole 9.

[0030] The locking mechanism 136 is fixed on one side of the mounting box 131 , and the locking mechanism 136 is connected to the mounting box 131 by rotating the locking mechanism 136 and the like.

[0031] A push rod 138 is movably provided on the inner wall of one side of the installation box 131, and a third spring is sleeved on the push rod 138. A through hole is provided on the inner wall of one side of the installation box 131, and a sealing ring is provided in the through hole. The inner wall of the sealing ring fits with the push rod 138. By pressing the pressure plate 12, the vertical rod 132 can drive the block 134 to move downward, and the block 134 squeezes the lock frame 136 to rotate it. When the inclined surfaces of the block 134 and the lock frame 136 are separated, the second spring 137 pushes the lock frame 136 to reset it, and the lock frame 136 is stuck on the block 134 to achieve the positioning of the vertical rod 132.

[0032] After the hemispherical body 142 at the bottom of the bottom pad 141 fits with the surface of the coil and fixes it, you can stop pressing the pressure plate 12 to achieve the positioning of the coil. When the coil needs to be taken out, squeeze the top rod 138 inward, and the top rod 138 causes the locking frame 136 to rotate and separate from the block 134. At this time, multiple first springs 10 push the sliding rod 11 upward, thereby separating the bottom pad 141 from the coil, and finally the coil can be taken out, replacing the traditional positioning mode, simplifying the operating steps when fixing and removing the coil, reducing operation time, and improving the working efficiency of the equipment.

[0033] In order to achieve the purpose of anti-slip, an anti-slip structure 14 is provided at the bottom of the pressure plate 12. The anti-slip structure 14 includes a bottom pad 141 fixedly connected to the bottom of the pressure plate 12. A plurality of hemispheres 142 are fixedly provided at the bottom of the bottom pad 141. The hemispheres 142 and the bottom pad 141 are both made of rubber. The bottom pad 141 and the hemispheres 142 can not only enhance the friction between the coil and achieve the purpose of anti-slip, but also the bottom pad 141 and the hemispheres 142 are both compressible and can complement the gaps between adjacent blocks 134 to improve the locking performance of the locking structure 13.

[0034] Working principle: When the test material needs to be fixed, first place the coil on the top of the test seat 7, then press the pressure plate 12 downward, the pressure plate 12 drives the slide bar 11 and the vertical rod 132, the slide bar 11 squeezes the first spring 10, the vertical rod 132 drives the block 134 on one side, the block 134 squeezes the lock frame 136 to make it rotate, and the lock frame 136 then squeezes the second spring 137 on one side.

[0035] When the locking block 134 and the inclined surface of the locking frame 136 are separated, the second spring 137 pushes the locking frame 136 to reset, and the locking frame 136 is stuck on the locking block 134 to achieve the positioning of the vertical rod 132. At this time, the vertical rod 132 can only be pressed down and cannot be pulled upward. When the hemisphere 142 at the bottom of the bottom pad 141 is in contact with the surface of the coil and fixed, the pressing plate 12 can stop being pressed. The bottom pad 141 and the hemisphere 142 not only enhance the friction between the coil and achieve the purpose of anti-slip, but also the bottom pad 141 and the hemisphere 142 are compressible and can complement the gap between the adjacent locking blocks 134, thereby improving the locking performance of the locking structure 13. When the coil needs to be removed, the top rod 138 is squeezed inwardly, and the top rod 138 causes the locking frame 136 to rotate and separate from the locking block 134. At this time, multiple first springs 10 push the sliding rod 11 upward, thereby separating the bottom pad 141 from the coil, and finally the coil can be taken out.
