Description

Technical Field

[0001] This utility model relates to the field of sealing performance testing technology, and in particular to a sealing performance testing device for a watertight connector. Background Technology

[0002] Watertight connectors are mainly used in scenarios where circuit or signal connections need to be established underwater or in humid environments. They enable power transmission, signal transmission, or data communication between underwater devices, such as underwater detectors, marine engineering equipment, and diving equipment, ensuring that the devices can be powered and receive / send signals normally underwater.

[0003] If a watertight connector has poor sealing performance during use, water or liquid seepage can lead to short circuits, equipment malfunctions, and even electrical leakage, posing safety hazards. To ensure safe operation of the equipment, watertight connectors must undergo sealing performance testing after manufacturing.

[0004] When testing the sealing performance of watertight connectors, the two openings on the left and right sides of the connector are sealed manually, and then the connector is placed in water to observe whether air bubbles are generated around it. This method of testing requires the connector to be air-dried after the test, which prolongs the testing cycle. Furthermore, judging the airtightness of the connector by manual observation has low accuracy. Utility Model Content

[0005] To address the technical problems of long testing cycles for watertight connectors in existing technologies, and the low accuracy of airtightness testing due to manual observation in judging the airtightness performance of watertight connectors, this utility model provides a sealing performance testing device for watertight connectors.

[0006] The sealing performance testing device for a watertight connector provided by this utility model adopts the following technical solution:

[0007] A sealing performance testing device for a watertight connector includes a testing platform and a conveyor chain for transporting the watertight connector. The conveyor chain is rotatably mounted on the upper part of the testing platform. The device is characterized by further including a fixing testing mechanism for fixing and testing the sealing performance of the watertight connector. The fixing testing mechanism is mounted on the conveyor chain. A first arc-shaped guide rod is provided at one end of the conveyor chain to move the fixing testing mechanism in a closing motion, and a second arc-shaped guide rod is provided at the other end of the conveyor chain to unlock the watertight connector. The device also includes an inflation cylinder for inflating and pressurizing the watertight connector, the inflation cylinder being mounted on the upper part of the testing platform.

[0008] By adopting the above technical solution, a fixed testing organization can automatically test the airtightness of watertight connectors, thereby improving the testing efficiency of watertight connectors.

[0009] Furthermore, baffles are welded to the upper positions on both sides of the testing platform, and the conveyor chain is rotatably positioned between the two baffles. A motor that drives the conveyor chain to rotate is fixedly installed at the bottom of the testing platform by bolts.

[0010] By adopting the above technical solution, the conveyor chain is rotated and positioned on the upper part of the testing table, thereby moving the position of the watertight connector.

[0011] Furthermore, the conveyor chain consists of multiple rotatingly connected conveyor plates.

[0012] By adopting the above technical solution, a stable transmission structure can be formed in the transmission chain.

[0013] Furthermore, an installation plate is fixedly installed on one side of the top of the testing platform, and an inflation cylinder is installed on the installation plate.

[0014] By adopting the above technical solution, the inflation cylinder can be installed on the test bench to facilitate inflation of the watertight connector.

[0015] Furthermore, the specific structure of the fixed detection mechanism includes a mounting base fixedly installed on the upper part of the conveyor plate and a fixing plate fixedly installed on the bottom of the conveyor plate. The conveyor plate is provided with a through mounting hole, and the fixing plate is fixedly installed at the bottom of the mounting hole. The upper part of the fixing plate has a sealing plug for sealing the bottom opening of the watertight connector.

[0016] By adopting the above technical solution, the opening at the bottom of the watertight connector can be sealed.

[0017] Furthermore, a sealing test head is rotatably connected to the upper part of the mounting base to seal the top opening of the watertight connector and to test the sealing performance of the watertight connector.

[0018] By adopting the above technical solution, the sealing performance of watertight connectors can be tested.

[0019] Furthermore, a connecting rod is rotatably connected to the top of the mounting base via a connecting arm. One end of the connecting rod is equipped with a sealing detection head, and the other end is fixedly connected to a linkage rod.

[0020] By adopting the above technical solution, the sealing detection head is rotated and positioned on the top of the mounting base.

[0021] Furthermore, the sealing detection head has a through air filling hole, the top of which has a one-way valve, and a pressure display is provided on the side of the sealing detection head to detect the internal gas pressure of the watertight connector.

[0022] By adopting the above technical solution, the watertight connector can be pressurized by adding air, and the internal pressure of the watertight connector can be detected by a pressure display, thereby detecting the sealing performance of the watertight connector.

[0023] In summary, the beneficial effects of this utility model are as follows:

[0024] This invention utilizes a fixed detection mechanism. During use, the watertight connector is mounted on a fixed plate, and a sealing plug seals the opening at the bottom of the connector. A motor-driven conveyor chain moves towards the inflation cylinder. During this movement, a first arc-shaped guide rod moves the sealing detection head towards the top opening of the watertight connector. When the watertight connector moves below the inflation cylinder, the cylinder moves downwards, pressing the sealing detection head into the top opening of the connector and inflating it. After inflation, the connector continues to move forward. A pressure indicator on the side of the sealing detection head detects pressure and checks for leaks. After testing, the connector continues to move forward under the driving force of the conveyor chain. A second arc-shaped guide rod causes the linkage rod to rotate in the opposite direction, removing the sealing detection head from the top opening of the connector and unlocking it. This device eliminates the need to immerse the watertight connector in water during testing, reducing the subsequent drying process and improving the efficiency of sealing performance testing. Furthermore, the use of a pressure display enhances the accuracy of the sealing performance test. Attached Figure Description

[0030] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0031] Example: Figures 1-4 The above describes a sealing performance testing device for a watertight connector.

[0032] Reference Figure 1 and Figure 2 As shown, this utility model discloses a sealing performance testing device for a watertight connector, including a testing platform 1 and a conveyor chain 2 for conveying the watertight connector 4. Baffles 11 are welded to the upper positions on both sides of the testing platform 1. The conveyor chain 2 is rotatably disposed between the two baffles 11. A motor for driving the conveyor chain 2 is fixedly mounted at the bottom of the testing platform 1 by bolts. The conveyor chain 2 is composed of multiple rotatably connected conveyor plates 22. It also includes a fixing and testing mechanism 3 for fixing and testing the sealing performance of the watertight connector 4. The fixing and testing mechanism 3 is disposed on the conveyor chain 2. A first arc-shaped guide rod 5 is provided at one end of the conveyor chain 2 to move the fixing and testing mechanism 3 in a closing motion. During the movement of the conveyor chain 2, the first arc-shaped guide rod 5 generates resistance to the fixing and testing mechanism 3, causing one end of the fixing and testing mechanism 3 to move in a closing motion towards the watertight connector 4. A second arc-shaped guide rod 7 is provided at the other end of the conveyor chain 2 to unlock the watertight connector 4 by the fixing and testing mechanism 3. It also includes an inflation cylinder 6 for inflating and pressurizing the watertight connector 4. Preferably, an mounting plate 12 is fixedly installed on one side of the top of the test platform 1, and the inflation cylinder 6 is installed on the mounting plate 12.

[0033] Reference Figure 2 and Figure 3As shown, the specific structure of the fixed detection mechanism 3 includes a mounting base 31 fixedly installed on the upper part of the conveyor plate 22 and a fixing plate 37 fixedly installed on the bottom of the conveyor plate 22. The conveyor plate 22 is provided with a through mounting hole, and the fixing plate 37 is fixedly installed at the bottom of the mounting hole. The upper part of the fixing plate 37 has a sealing plug 371 for sealing the bottom opening of the watertight connector 4. In use, the watertight connector 4 is placed on the fixing plate 37, and the sealing plug 371 on the fixing plate 37 is inserted into the bottom opening of the watertight connector 4 to seal the bottom opening of the watertight connector 4.

[0034] Furthermore, a sealing detection head 36 is rotatably connected to the upper part of the mounting base 31 to seal the top opening of the watertight connector 4 and to test the sealing performance of the watertight connector 4. Preferably, a connecting rod 33 is rotatably connected to the top of the mounting base 31 via a connecting arm 32. One end of the connecting rod 33 is provided with the sealing detection head 36, and the other end is fixedly connected to a connecting rod 34. By contacting the bottom wall of the first arc-shaped guide rod 5, the connecting rod 34 rotates upward, causing the sealing detection head 36 to seal the top opening of the watertight connector 4. By contacting the top wall of the second arc-shaped guide rod 7, the connecting rod 34 rotates downward, thereby removing the sealing detection head 36 from the top opening of the watertight connector 4. The sealing detection head 36 has a through air filling hole with a one-way valve 361 at the top. A pressure display 362 for detecting the internal gas pressure of the watertight connector 4 is provided on the side of the sealing detection head 36.

[0035] In use, the watertight connector 4 is mounted on the fixing plate 37 through the mounting holes in the conveyor plate 22, and the opening at the bottom of the watertight connector 4 is sealed by the sealing plug 371 on the fixing plate 37. Then, the motor is started, driving the conveyor chain 2 to move towards the inflation cylinder 6. During this movement, the first arc-shaped guide rod 5 contacts the bottom wall of the connecting rod 34 in the fixed detection mechanism 3, causing the sealing detection head 36 to move towards the top opening of the watertight connector 4. When the watertight connector 4 moves below the inflation cylinder 6, the inflation cylinder 6 moves downwards, pressing the sealing detection head 36 against the top of the watertight connector 4. The watertight connector 4 is inflated inside the opening. After inflation, the inflation cylinder 6 moves to the initial position, and the watertight connector 4 continues to move forward. The pressure display 362 on the side of the sealing detection head 36 detects the pressure of the watertight connector 4 to check for air leakage. After the test, the watertight connector 4 continues to move forward under the driving force of the conveyor chain 2. Subsequently, the second arc-shaped guide rod 7 contacts the top wall of the linkage rod 34 in the fixed detection mechanism 3, causing the linkage rod 34 to rotate in the opposite direction. At this time, the sealing detection head 36 moves out of the opening at the top of the watertight connector 4, unlocking the watertight connector 4. This device eliminates the need to immerse the watertight connector 4 in water during the testing process, reducing the subsequent drying steps and improving the efficiency of the sealing performance test. Furthermore, the use of the pressure display 362 also improves the accuracy of the sealing performance test.
