Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0026] In the embodiments of this application, reference is made to Figure 1 , Figure 2 , Figure 3 and Figure 4This application provides a watertightness testing device 100 for testing the watertightness of a rubber part 200, thereby overcoming the problem of low testing efficiency of existing testing devices.

[0027] Specifically, the watertightness testing device 100 has a first direction X, a second direction Z, and a third direction Y that intersect each other. For example, the watertightness testing device 100 also has a first direction X, a second direction Z, and a third direction Y that are perpendicular to each other. Here, "perpendicular" refers to a state where the angle formed by two lines, a line and a surface, or a surface is 89° to 91°.

[0028] Specifically, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The watertightness testing device 100 includes: a base frame 110, a water tank 120, and a fixing unit 130. The water tank 120 is rotatably mounted on the base frame 110, and the water tank 120 is provided with a receiving cavity 121 having an opening 122, the receiving cavity 121 containing a liquid medium; the fixing unit 130 is installed on the side of the water tank 120 near the opening 122, and the fixing unit 130 is used to fix the rubber part 200 to be tested.

[0029] The liquid medium can be any one of pure water, tap water, simulated seawater, or dyed water, but is not limited to these.

[0030] Specifically, under the drive of an external force, the water tank 120 rotates around the base frame 110 at a certain angle to control the liquid medium to immerse the rubber part 200 to be tested. For example, in this application, under the drive of an external force, the water tank 120 rotates 180° around the base frame 110 to control the water tank 120 to be in an inverted state, thereby immersing the rubber part 200 to be tested for water tightness.

[0031] The external force can be provided manually or by mechanical equipment. This application does not make specific limitations and the choice can be made according to the actual situation.

[0032] Understandably, when a water tightness test is required on the rubber part 200, the staff first injects a certain amount of liquid medium into the water storage tank 120 according to the test requirements. Then, the staff installs the rubber part 200 to be tested on the fixing unit 130. After installation, the staff drives the water storage tank 120 to rotate 180° around the base frame 110 to control the water storage tank 120 to be in an inverted state so that the liquid medium can immerse the rubber part 200 to be tested. After standing for a period of time, the staff observes whether the rubber part 200 leaks liquid medium to determine the water tightness of the rubber part 200. After the test is completed, the staff drives the water storage tank 120 to rotate 180° around the base frame 110 again to control the water storage tank 120 to be in an upright state. The rubber part 200 that has been tested is removed from the fixing unit 130, and the above operation is repeated for another rubber part 200 to be tested.

[0033] This application controls the water tank 120 to rotate around the base frame 110 by a certain angle, thereby controlling the immersion of the rubber part 200 to be tested by the liquid medium. This allows the water tank 120 to perform multiple water tightness tests on the rubber part 200 with a single injection of liquid medium, eliminating the need for repeated injection and discharge of liquid medium. This improves the testing efficiency of the water tightness testing device 100 while ensuring the accuracy of the test results, thus improving the working efficiency of the water tightness testing device 100. At the same time, this application has a simple structure, is easy to manufacture and assemble, and reduces production costs.

[0034] In some embodiments, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 In order to further improve the testing efficiency of the watertightness testing device 100, in this application, at least two water storage tanks 120 and fixing units 130 are provided. Each water storage tank 120 and the previous fixing unit 130 are spaced apart in the first direction X, and each water storage tank 120 can be rotatably installed on the base frame 110. Each fixing unit 130 is installed on the side of the corresponding water storage tank 120 near the opening 122.

[0035] This application improves testing efficiency by setting up multiple water storage tanks 120 and multiple fixing units 130 to simultaneously conduct water tightness tests on multiple rubber parts 200 to be tested.

[0036] In some embodiments, multiple water storage tanks 120 and multiple fixing units 130 can simultaneously perform water tightness tests on multiple rubber parts 200 of the same type, or simultaneously perform water tightness tests on multiple rubber parts 200 of different types. This application does not make specific limitations, and the appropriate method can be selected according to the actual situation.

[0037] In some embodiments, refer to Figure 1 and Figure 2 The fixing unit 130 includes a first fixing member 131 and a second fixing member 132. The first fixing member 131 is installed on the side of the water storage tank 120 near the opening 122, and the first fixing member 131 has a receiving groove 1311. The receiving groove 1311 communicates with the receiving cavity 121 and is used to receive the rubber part 200. The second fixing member 132 is movably installed on the side of the first fixing member 131 away from the water storage tank 120 and is used to position and fix the rubber part 200 located in the receiving groove 1311.

[0038] Understandably, after the rubber part 200 to be tested is placed in the receiving groove 1311, the operator can drive the second fixing member 132 to move towards the first fixing member 131, so as to control the second fixing member 132 to press and fix the rubber part 200 located in the receiving groove 1311, thereby positioning and fixing the rubber part 200 to prevent the rubber part 200 from moving randomly during the rotation of the water tank 120, thereby further improving the testing efficiency of the water tightness testing device 100; at the same time, it reduces the influence of other factors on the test results and improves the accuracy of the test results of the water tightness testing device 100.

[0039] In some embodiments, refer to Figure 5 and Figure 7 The fixing unit 130 further includes: a plurality of first locking members 133, which are movably installed on the side of the first fixing member 131 away from the water storage tank 120, and each first locking member 133 is arranged sequentially at intervals along the circumference of the second fixing member 132 on the outer periphery of the second fixing member 132. The first locking members 133 are used to lock or release the second fixing member 132.

[0040] Understandably, when testing the rubber part 200, the operator places the rubber part 200 to be tested into the receiving groove 1311, and then drives the second fixing member 132 to move towards the first fixing member 131, so as to control the second fixing member 132 to press and fix the rubber part 200 located in the receiving groove 1311. Then, the operator drives the first locking member 133 to move towards the second fixing member 132, so as to control the first locking member 133 to abut against the second fixing member 132, so as to lock the second fixing member 132, thereby keeping the relative position between the first fixing member 131 and the second fixing member 132 unchanged.

[0041] After the rubber part 200 is tested, the staff drives the first locking member 133 to move away from the second fixing member 132, so as to control the first locking member 133 to release the second fixing member 132. The staff then drives the second fixing member 132 to move away from the first fixing member 131, and then takes out the tested rubber part 200 from the self-accommodating groove 1311.

[0042] This application sets multiple first locking members 133 to lock the second fixing member 132, thereby positioning and fixing the rubber member 200 located in the receiving groove 1311, further preventing the rubber member 200 from moving freely during the rotation of the water storage tank 120, thereby further improving the testing efficiency of the water tightness testing device 100; at the same time, it reduces the influence of other factors on the test results and improves the accuracy of the test results of the water tightness testing device 100.

[0043] In some embodiments, for the convenience of viewing the test results, reference is made in this application. Figure 1 and Figure 2 , Figures 5 to 8 The second fixing member 132 has a through hole 1321, which is connected to the receiving groove 1311.

[0044] The watertightness testing device 100 also includes a detection element 140, which is installed in the through hole 1321 of the second fixing member 132 and is in contact with the side of the rubber part 200 away from the water storage tank 120.

[0045] Specifically, the detection element 140 emits a detection signal upon contact with the liquid medium. This detection signal can be light, sound, image, text, color, etc. For example, in this application, the detection signal is color, meaning that the detection element 140 changes color upon contact with the liquid medium.

[0046] Understandably, if the detection element 140 changes color during the water tightness test of the rubber part 200, it indicates that the rubber part 200 has leaked liquid medium and its water tightness is poor.

[0047] If the detection element 140 does not change color, it indicates that the rubber part 200 has excellent water tightness.

[0048] This application improves the testing efficiency of the watertightness testing device 100 by setting up a detection element 140 so that the detection signal of the detection element 140 can be easily viewed by the staff.

[0049] For example, in this application, the detection element 140 can be a test strip. The test strip will change color after contacting the liquid medium, so that the staff can easily view the water tightness test results of the rubber part 200 to be tested.

[0050] In some embodiments, refer to Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8The watertightness testing device 100 further includes a rotating unit 150, which includes a first rotating component 151 and a second rotating component 152. At least two first rotating components 151 and two second rotating components 152 are provided. Each first rotating component 151 and each second rotating component 152 are located on opposite sides of the water storage tank 120 in the first direction X. The first rotating component 151 is installed on the water storage tank 120, and the second rotating component 152 is installed on the base frame 110. The first rotating component 151 and the second rotating component 152 are rotatably connected.

[0051] This application utilizes the cooperation between the first rotating component 151 and the second rotating component 152 to drive the water storage tank 120 to rotate, thereby facilitating the operation of the watertightness testing device 100 by the staff and further improving the testing efficiency of the watertightness testing device 100; at the same time, this application has a simple structure and reduces production costs.

[0052] In some embodiments, refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 The first rotating member 151 has a first locking hole 1511 and a second locking hole 1512. The first locking hole 1511 and the second locking hole 1512 are respectively located on opposite sides of the first rotating member 151 in the second direction Z, and the first locking hole 1511 is positioned close to the fixing unit 130 relative to the second locking hole 1512.

[0053] The first locking hole 1511 and the second locking hole 1512 can both be of any shape. For example, both the first locking hole 1511 and the second locking hole 1512 are circular holes, but are not limited thereto.

[0054] Specifically, the rotating unit 150 further includes a second locking member 153, which is installed on the base frame 110 near the area of ​​the first rotating member 151, and the second locking member 153 can be selectively embedded in the first locking hole 1511 or the second locking hole 1512. Specifically, when the second locking member 153 is embedded in the first locking hole 1511, it locks the water tank 120 in the upright position; when the second locking member 153 is embedded in the second locking hole 1512, it locks the water tank 120 in the inverted position.

[0055] This application provides a second locking member 153 to lock the water tank 120 in an upright or inverted state by utilizing the cooperation between the second locking member 153 and the first rotating member 151. This facilitates the operation of the watertightness testing device 100 by the operator and helps ensure that the watertightness testing device 100 can efficiently perform watertightness testing on the rubber part 200, thereby improving the testing efficiency of the watertightness testing device 100.

[0056] In some embodiments, the second locking member 153 can be driven manually or mechanically. This application does not make specific limitations, and it can be set according to the actual situation.

[0057] In some embodiments, the watertightness testing device 100 further includes a driver (not shown) installed on the base frame 110 in the area near the first rotating member 151, and the power output end of the driver is connected to the first rotating member 151 in a transmission connection. The driver is used to drive the first rotating member 151 to rotate, thereby driving the water storage tank 120 to rotate. It does not require manual operation, has a high degree of automation, and further improves the testing efficiency of the watertightness testing device 100.

[0058] The driver can be any one of a drive motor, a drive cylinder, or an electromagnet, but is not limited to this.

[0059] In some embodiments, refer to Figure 1 , Figure 2 and Figure 3 The watertightness testing device 100 also includes a measuring element 180 installed in the water storage tank 120. The measuring element 180 is used to measure the liquid level of the liquid medium located in the receiving cavity 121, so that the operator can add an appropriate amount of liquid medium into the receiving cavity 121, which helps to improve the accuracy of the test results of the watertightness testing device 100.

[0060] In some embodiments, refer to Figure 3 Two measuring elements 180 are provided. The two measuring elements 180 are respectively provided on both sides of the water storage tank 120 in the second direction Z, so that the liquid level of the liquid medium in the receiving cavity 121 can be measured by the measuring elements 180 when the water storage tank 120 is in the upright state or the inverted state.

[0061] For example, in this application, the measuring element 180 is a ruler, but it is not limited thereto.

[0062] In some embodiments, refer to Figure 3 and Figure 4 The watertightness testing device 100 also includes a drain tank 160 and a drain valve 170. The drain tank 160 is installed on the base frame 110. Specifically, the drain tank 160 is installed on the side of the base frame 110 away from the water storage tank 120 in the second direction Z. The drain valve 170 is installed on the side of the water storage tank 120 away from the opening 122. The drain valve 170 is used to connect the receiving cavity 121 with the drain tank 160.

[0063] Understandably, when it is necessary to replace the liquid medium in the water storage tank 120, the staff will control the water storage tank 120 to be in the upright position and then open the drain valve 170. The liquid medium in the water storage tank 120 will be discharged into the drain tank 160 through the drain valve 170. After the liquid medium is completely discharged, the staff will close the drain valve 170 and inject the new liquid medium into the water storage tank 120.

[0064] In summary, the working process of the water tightness testing device 100 in this application is as follows: When a water tightness test is required on the rubber part 200, the operator controls the second locking member 153 to be embedded in the first locking hole 1511 to lock the water tank 120 in the upright position; the operator then injects a certain amount of liquid medium into the water tank 120 according to the test requirements and with reference to the scale of the measuring element 180; after the injection is completed, the operator places the rubber part 200 to be tested into the receiving groove 1311, and then drives the second fixing member 132 to move towards the direction of the first fixing member 131, so as to control the second fixing member 132 to press and fix the rubber part 200 located in the receiving groove 1311, and then drives the first locking member 133 to move towards the direction of the second fixing member 132, so as to control the first locking member 133 to abut against the second fixing member 132. Next, the second fixing member 132 is locked, thereby locking the rubber part 200. After installation, the operator controls the second locking member 153 to move out of the first locking hole 1511, and then drives the water tank 120 to rotate 180° around the base frame 110 to control the water tank 120 to be in an inverted state so that the liquid medium immerses the rubber part 200 to be tested. Then, the operator controls the second locking member 153 to be embedded in the second locking hole 1512 to lock the inverted water tank 120. The inverted water tank 120 is left to stand for a period of time, and the color of the detection element 140 is observed. If the color of the detection element 140 changes, it indicates that the rubber part 200 has leaked liquid medium and the water tightness of the rubber part 200 is poor. If the color of the detection element 140 does not change, it indicates that the water tightness of the rubber part 200 is excellent.

[0065] After the test is completed, the staff controls the second locking member 153 to move out of the second locking hole 1512, and then drives the water tank 120 to rotate 180° around the base frame 110 again to control the water tank 120 to be in the upright position. The staff then controls the second locking member 153 to be embedded in the first locking hole 1511 to lock the water tank 120 in the upright position. The staff then drives the first locking member 133 to move away from the second fixing member 132 to control the first locking member 133 to release the second fixing member 132. The staff then drives the second fixing member 132 to move away from the first fixing member 131. The staff then takes out the tested rubber part 200 from the receiving groove 1311 and repeats the above operation on another rubber part 200 to be tested.

[0066] The above steps are provided only to help understand the method, structure, and core ideas of this application. Those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims.
