Technical Field

[0001] This utility model relates to the field of condom production and testing technology, specifically a device for testing the tensile strength of condoms. Background Technology

[0002] A condom is a barrier device that can be used during sexual intercourse to reduce sexually transmitted infections. It is one of the simplest ways to prevent pregnancy without medication. The raw materials of condoms are mainly latex, plastic or sheepskin membrane, so their strength and elasticity vary greatly. Before each batch of condoms is produced, a sample is made in advance, and its performance is determined by testing.

[0003] However, current condom performance testing devices are difficult to support condoms of different sizes and are inconvenient to perform lateral and vertical tensile tests, causing inconvenience in use. Therefore, we propose a condom tensile performance testing device. Utility Model Content

The movable frame 406 is connected, and the second slide groove 407 is opened on the surface of the frame 1. The connecting plate 408 is slidably connected to the second slide groove 407. One end of the connecting plate 408 passes through the second slide groove 407 and is connected to the tension rod 409. The second motor 401 drives the threaded rod 402 to rotate, causing the third threaded cylinder 403 to move. In conjunction with the slide rail 404 and the third slider 405, the movable frame 406 moves, thereby causing the connecting plate 408 to move inside the second slide groove 407, causing the tension rod 409 to move. One end of the tension rod 409 is inserted into the condom for a vertical tensile test.

[0023] Specifically, the clamping mechanism 3 includes a first motor 301, which is mounted on the surface of the support frame 2. A bidirectional threaded rod 302 is mounted on the output end of the first motor 301. A first threaded cylinder 303 and a second threaded cylinder 310 are mounted on the surface of the bidirectional threaded rod 302. The first threaded cylinder 303 and the second threaded cylinder 310 are symmetrically threaded and mounted on the surface of the bidirectional threaded rod 302. The clamping mechanism 3 includes a first sliding groove 304. A first slider 305 and a second slider 311 are slidably mounted inside the first sliding groove 304. The first slider 305 and the second slider 311 are... Symmetrically installed, one end of the first slider 305 is connected to the first threaded cylinder 310, and one end of the second slider 311 is connected to the second threaded cylinder 310. The clamping mechanism 3 includes a first connecting frame 306, which is mounted on the surface of the first threaded cylinder 303. A first electric push rod 307 is mounted on the surface of the first connecting frame 306, and one end of the first electric push rod 307 passes through the first connecting frame 306 and is welded to a first clamping plate 308. A first support plate 309 is provided on the surface of the first connecting frame 306. The clamping mechanism 3 also includes a second connecting frame 312.

A second support plate 315 is welded to the surface of the second connecting frame 312. The first support plate 309 and the second support plate 315 are symmetrical. The condom to be tested is inserted into the surfaces of the first support plate 309 and the second support plate 315. The first electric push rod 307 moves the first clamping plate 308, causing the first clamping plate 314 to move. 08. When the condom comes into contact, the second electric push rod 313 moves the second clamping plate 314, making the second clamping plate 314 contact the condom, thereby fixing the condom. The first motor 301 drives the bidirectional threaded rod 302 to rotate, causing the first threaded cylinder 303 and the second threaded cylinder 310 to move. In conjunction with the first sliding groove 304, the first slider 305, and the second slider 311, the first connecting frame 306 and the second connecting frame 312 move, thereby causing the first support plate 309 and the second support plate 315 to move away from each other, and performing a lateral tensile test on the condom.

[0024] All electrical devices in this invention are powered by an external power source;

[0025] Working principle and usage procedure: The condom to be tested is inserted into the surfaces of the first support plate 309 and the second support plate 315. The first electric push rod 307 moves the first clamping plate 308, bringing it into contact with the condom. The second electric push rod 313 moves the second clamping plate 314, bringing it into contact with the condom, thus securing it. The first motor 301 drives the bidirectional threaded rod 302 to rotate, causing the first and second threaded cylinders 303 to move. This, in conjunction with the first sliding groove 304, the first slider 305, and the second slider 311, moves the first connecting frame 306 and the second connecting frame 312, thereby moving the first support plate 309 and the second support plate 315 away from each other. A lateral tensile test is performed on the condom. The second motor 401 drives the threaded rod 402 to rotate, causing the third threaded cylinder 403 to move. This, in conjunction with the movement of the slide rail 404 and the third slider 405, moves the moving frame 406, thereby causing the connecting plate 408 to move inside the second slide groove 407. This causes the tension rod 409 to move, and one end of the tension rod 409 is inserted into the condom for a vertical tensile test. The surface of the bidirectional threaded rod 302 has two symmetrically arranged threads in opposite directions. The first motor 301 drives the bidirectional threaded rod 302 to rotate, causing the first threaded cylinder 303 and the second threaded cylinder 310 to move closer to or further away from each other, thereby causing the first connecting frame 306 and the second connecting frame 312 to move closer to or further away from each other.
