Description

Technical Field

[0001] This utility model relates to the field of condom quality testing, and in particular to a testing device for finished condoms. Background Technology

[0002] A condom is a barrier contraceptive device that primarily prevents sperm from meeting an egg, thus achieving contraception. After the condoms are manufactured, samples are taken and then tested using a testing device to determine if there are pinholes or leaks.

[0003] Chinese Patent CN220380699U discloses a condom leakage detection device, including a water inlet assembly, a rotating assembly, and multiple clamping assemblies. The rotating assembly includes a sleeve, an upper fixing plate, and multiple connecting cylinders. The water inlet assembly is equipped with a drive assembly for driving the upper fixing plate to rotate. The sleeve is fitted onto the water inlet assembly. The upper fixing plate is mounted on the sleeve. Multiple connecting cylinders are mounted on the bottom surface of the upper fixing plate. Multiple clamping assemblies are mounted on the bottom surface of the upper fixing plate. The detection device uses a drive motor to rotate the upper fixing plate, allowing the user to stand still and place multiple condoms onto the multiple connecting cylinders. The multiple clamping assemblies then press the condoms firmly onto the connecting cylinders. Liquid from a water tank is then injected into the condoms through the connecting cylinders via a connecting pipe, thus performing a water injection test. The rotation of the upper fixing plate also facilitates long-term hanging testing of the installed condoms.

[0004] However, the above technical solution has the following shortcomings: The device uses the elasticity of the telescopic rod to pull the two semi-rings to press the condom into the slot, thereby achieving the clamping and limiting of the condom. However, when water is introduced into the condom, the condom will deform due to the downward acceleration applied by the water, which will pull the semi-rings. This may cause the spring in the telescopic rod to stretch and cause the condom to fall off. Furthermore, when operating the clamping component, it is necessary to use your fingers to support and stretch the spring, which is inconvenient to use. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a testing device for finished condoms, improving the clamping structure of the condoms, and enhancing the convenience of use and the stability of the condoms.

[0006] The present invention provides a testing device for finished condoms, comprising a turntable and a clamping mechanism. A support column is coaxially arranged on the turntable, and a mounting plate is arranged on the top of the support column. The clamping mechanism includes a plurality of fixed frames arranged in a ring array on the mounting plate, a cylinder and a fixed block arranged on the fixed frame, two connecting blocks symmetrically distributed on the fixed blocks, a rotating arm rotatably connected to the connecting blocks at one end, a clamping frame arranged at the end of the rotating arm away from the connecting blocks, a moving rod driven and connected to the cylinder, a fixed plate arranged at the end of the moving rod, and two connecting rods rotatably connected to the fixed plate and the rotating arm at their respective ends. The moving rod is slidably connected to the fixed block, and the rotating arm has a bent portion.

[0015] Example 1, as Figure 1 - Figure 4 As shown, the present embodiment proposes a testing device for finished condoms, including a turntable 1 and a clamping mechanism; a support column 2 is coaxially arranged on the turntable 1, and an installation plate 3 is arranged on the top of the support column 2. Multiple water delivery cylinders 14 are arranged in a ring array on the installation plate 3.

[0016] The clamping mechanism includes multiple fixed frames 4 arranged in a ring array on the mounting plate 3, cylinders 5 and fixed blocks 6 set on the fixed frames 4, two connecting blocks 7 symmetrically distributed on the fixed blocks 6, a rotating arm 8 rotatably connected to the connecting blocks 7 at one end, a clamping frame 9 set at the end of the rotating arm 8 away from the connecting blocks 7, a moving rod 10 driven by the cylinders 5, a fixed plate 11 set at the end of the moving rod 10, and two connecting rods 12 rotatably connected to the fixed plate 11 and the rotating arm 8 at both ends respectively; the moving rod 10 is slidably connected to the fixed block 6, the rotating arm 8 has a bent part, the inner side of the clamping frame 9 is provided with anti-slip ridges 13, and the clamping frame 9 is located on both sides of the water delivery cylinder 14.

[0017] In this embodiment, when a sampled condom needs to be tested, the opening of the condom is first pulled open and placed on the lower end of the water delivery cylinder 14. Then, the cylinder 5 is activated to drive the moving rod 10 to retract in the direction of the cylinder 5. The moving rod 10 drives the fixed plate 11 to move, causing the end of the connecting rod 12 that is hinged to the fixed plate 11 to deflect. Then, the other end of the connecting rod 12 pulls the middle of the rotating arm 8, causing the rotating arm 8 to rotate around the pin that is hinged to the connecting block 7 as the rotation center. Then, the clamping frames 9 on both sides of the water delivery cylinder 14 move closer to each other until the clamping frames 9 clamp the outer surface of the condom onto the outer wall of the water delivery cylinder 14. The elastic anti-slip protrusions 13 not only prevent damage to the clamping surface of the condom, but also improve the stability of the clamping. This avoids the problem of the condom falling off due to impact deformation during water delivery. The operation is simple and convenient, and it has good practicality.

[0018] Example 2, as Figure 1 and Figure 3As shown, this embodiment proposes a testing device for finished condoms. Compared with the first embodiment, in this embodiment, the top of the water delivery cylinder 14 is provided with a funnel 15, and two fitting plates 16 are provided on the water delivery cylinder 14. The fitting plates 16 are engaged with the mounting plate 3. The turntable 1 is provided with multiple receiving grooves 17, and a connecting seat 18 is provided on the turntable 1. A base 19 is provided below the connecting seat 18.

[0019] In this embodiment, the funnel 15 of the water delivery cylinder 14 is used to receive the water delivered from above. The water enters the interior of the condom through the water delivery cylinder 14. The quality of the condom is judged by observing whether there is leakage. The fitting plate 16 is used to fix the water delivery cylinder 14 on the mounting plate 3.

[0020] It should be noted that the device is also equipped with a water delivery device (not shown). The water in the storage tank is pumped into the water delivery cylinder 14 through the pump body and then into the condom. The device is used in conjunction with components such as a solenoid valve and a time controller to achieve the water delivery volume. After the test is completed, the water in the condom is poured into the water tank. The water delivery device is a mature existing technology and this part is not an innovation of this application. The technical effect of this application is achieved entirely through the aforementioned mechanical structure improvement.

[0021] Example 3, as Figure 4 As shown, this embodiment proposes a testing device for finished condoms. Compared with Embodiment 2, in this embodiment, the base 19 is provided with a rotating assembly. The rotating assembly includes a rotating shaft 20 coaxially mounted on a connecting seat 18, a motor 21 mounted inside the base 19, a first gear 22 driven and connected to the motor 21, and a second gear 23 coaxially mounted on the rotating shaft 20. The first gear 22 and the second gear 23 are meshed and connected. The rotating shaft 20 is rotatably connected to the base 19. Four rollers 24 arranged in a circular array are rotatably connected to the connecting seat 18. The rollers 24 are rolled on the base 19.

[0022] In this embodiment, the device can drive the turntable 1 and the mounting plate 3 on it to rotate through the set rotating component, so as to fix and test multiple sampled condoms at the same time. At the same time, the operator does not need to adjust his body position. When rotating, the motor 21 needs to be started to drive the first gear 22 to rotate. The first gear 22 and the second gear 23 mesh and transmit power. Then, the second gear 23 drives the connecting seat 18 and the turntable 1 to rotate through the rotating shaft 20, thereby realizing the adjustment of the work position. After all the condoms are fixed in the work position, the water delivery test can be performed. In addition, the roller 24 can reduce the friction when the connecting seat 18 rotates, thus reducing energy consumption.

[0023] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
