[0036] The following reference Figures 1 to 5 The waterproof inspection device provided by this utility model will be described.

[0037] Reference Figures 1 to 4 The waterproof inspection device includes a housing 1, a control module 2, and an image acquisition module 3. The housing 1 is generally cylindrical. The image acquisition module 3 is located inside the housing 1, near one end of the housing 1. A viewing window 15 is provided at one end of the housing 1 corresponding to the position of the image acquisition module 3. The image acquisition module 3 is configured to acquire images of the inspected area through the viewing window 15. The control module 2 and the image acquisition module 3 are electrically connected, and the control module 2 is used to control the operation of the image acquisition module 3 to acquire the corresponding images as needed for the inspection.

[0038] Specifically, the outer casing 1 includes a first casing 11 and a second casing 12. The second casing 12 covers and is positioned on the opening side of the first casing 11, forming a receiving cavity 13 between the first casing 11 and the second casing 12. The connection between the first casing 11 and the second casing 12 is sealed by a sealing part 4. The sealing part 4 seals the joint between the first casing 11 and the second casing 12 to prevent liquid from seeping into the receiving cavity 13 through the joint of the outer casing 1, thereby improving the waterproof effect of the joint of the outer casing 1.

[0039] Regarding the positioning method of the first housing 11 and the second housing 12, in this embodiment, the first housing 11 and the second housing 12 are engaged by the cooperation of buckles and slots. Specifically, the inner wall of the first housing 11 is connected with multiple buckles, and the inner wall of the second housing 12 has slots for each buckle position. Thus, the first housing 11 and the second housing 12 are installed and positioned by engaging, which makes installation more convenient and less prone to loosening. In other embodiments, the first housing 11 and the second housing 12 can also be connected by adhesive or screws.

[0040] It should be noted that in this embodiment, the first shell 11 and the second shell 12 are both integral structures, but in some other embodiments, the first shell 11 and the second shell 12 may also be segmented or spliced.

[0041] For example, the sealing part 4 includes a first sealing ring 41 and a second sealing ring 42, which are arranged sequentially from the inside to the outside of the receiving cavity 13. The first sealing ring 41 is integrally formed on the first housing 11 and abuts against the second housing 12, and the second sealing ring 42 is integrally formed on the second housing 12 and abuts against the first housing 11.

[0042] As described above, by setting the first sealing ring 41 to form a step on the side where the first housing 11 and the second housing 12 mate, and by setting the second sealing ring 42 to form a step on the side where the second housing 12 mates with the first housing 11, a tortuous liquid penetration path is formed at the joint between the first housing 11 and the second housing 12 after assembly, thereby improving the water-proof effect. In addition, the step design can disperse the stress at the joint, preventing the gap from widening due to mechanical deformation or temperature changes, thus maintaining long-term waterproof performance. It should be added that the first sealing ring 41 is integrally formed into the first housing 11, and the second sealing ring 42 is integrally formed into the second housing 12, to improve the working stability of the first sealing ring 41 and the second sealing ring 42, as well as the waterproofness of the outer shell 1.

[0043] Optionally, in some other embodiments, the sealing part 4 may also be sealing teeth disposed on the first housing 11 and the second housing 12, and the sealing teeth on the first housing 11 and the second housing 12 may mesh with each other. The sealing part 4 may also be a sealing gasket.

[0044] Furthermore, a sealing strip 43 is provided between the first sealing ring 41 and the second housing 12. In this embodiment, the sealing strip 43 is made of rubber and is in a compressed state, thereby further sealing the gap between the first sealing ring 41 and the second housing 12 to improve the sealing effect between the first housing 11 and the second housing 12. It should be noted that in some other embodiments, the sealing strip 43 may also be obtained by drying other materials of sealant.

[0045] Optionally, in some other embodiments, the sealing strip 43 may be disposed between the second sealing ring 42 and the first housing 11, or the sealing strip 43 may be disposed between the first sealing ring 41 and the second sealing ring 42.

[0046] Reference Figure 3 and Figure 4 The control module 2 includes a circuit board 21 and at least one button body 22. The circuit board 21 is placed inside the receiving cavity 13 and has control contacts 211. A button window 14 is provided on the housing 1 corresponding to the position of the control contacts 211. The button body 22 is placed at the button window 14. A sealing member 5 is connected inside the receiving cavity 13 to isolate the receiving cavity 13 from the button body 22. The sealing member 5 can transmit the pressure applied to the button body 22 to the control contacts 211. By isolating the receiving cavity 13 from the button window 14 through the sealing member 5, liquid is prevented from seeping into the receiving cavity 13 through the button window 14, thereby improving the waterproof effect at the button window 14 and greatly improving the overall waterproof performance of the waterproof inspection device.

[0047] For example, in this embodiment, the circuit board 21 has four control contacts 211 to receive four different commands, and the button body 22 is provided for each control contact 211, that is, there are also four button bodies 22. In this embodiment, there are two button windows 14, one button window 14 has three button bodies 22 inside, and the other button window 14 has one button body 22 inside; in some other embodiments, only one button window 14 may be provided.

[0048] Furthermore, to limit the movement of the seal 5, multiple limiting posts 131 are arranged circumferentially around the seal 5 inside the receiving cavity 13 to form a limiting area for the seal 5. In this embodiment, the limiting posts 131 are integrally formed with the outer shell 1 to improve the working stability of the limiting posts 131. A limiting groove 511 is provided on the seal 5 corresponding to the position of each limiting post 131, with a portion of the limiting post 131 located inside the limiting groove 511.

[0049] With the above settings, the sealing element 5 is limited by the limiting post 131, making the relative position of the sealing element 5 and the button window 14 less prone to change, thereby improving the stability of the sealing element 5 during operation. Optionally, in some other embodiments, the limiting groove 511 may be omitted.

[0050] It is worth noting that the circuit board 21 is connected to the limiting post 131 via a connector. In this embodiment, the connector is a screw, meaning that the circuit board 21 is directly fixed to the limiting post 131 by screws, thus securing the circuit board 21. Optionally, in some other embodiments, the circuit board 21 can also be glued to the limiting post 131.

[0051] Reference Figure 3 and Figure 5 For example, the sealing element 5 includes a window sealing ring 51 and a spacer 52. The window sealing ring 51 is sealed to the inner wall of the housing 1, and the button window 14 is located in the inner ring of the window sealing ring 51. In this embodiment, the window sealing ring 51 is bonded to the inner wall of the housing 1. The limiting post 131 is disposed in the outer ring of the window sealing ring 51. The spacer 52 is integrally formed on one side of the window sealing ring 51 and closes the opening of the window sealing ring 51. The spacer 52 is elastic. By setting the spacer 52 at the opening of the window sealing ring 51, the window sealing ring 51 is used as the mounting base of the spacer 52, and the thinner spacer 52 deforms to transmit pressure, so that the window sealing ring 51 itself does not need to undergo large deformation, thereby improving the working stability of the sealing ring 51. Optionally, in some other embodiments, the sealing element 5 can also be directly set as a sheet and cover the button window 14.

[0052] Furthermore, the inner ring of the window sealing ring 51 is spaced apart from the button window 14, and the isolation plate 52 is also spaced apart from the button window 14. A limiting part 221 is provided on the periphery of the button body 22. The limiting part 221 is located between the isolation plate 52 and the inner wall of the outer shell 1. In this embodiment, the limiting part 221 is integrally formed on the flange of the button body 22. By limiting the button body 22 by the limiting part 221 extending between the isolation plate 52 and the inner wall of the outer shell 1, the button body 22 can be prevented from detaching from the button window 14. Optionally, in some other embodiments, the limiting part 221 may also be a limiting block.

[0053] It should be added that in some other embodiments, the limiting part 221 may not be necessary, and the button body 22 may be directly bonded to the isolation sheet 52, which can also achieve the limiting of the button body 22.

[0054] In addition, the isolating plate 52 is provided with a protrusion 521 facing the button body 22 for each button body 22. The protrusion 521 abuts against the back of the button body 22. The protrusion 521 is provided to increase the strength of the isolating plate 52 itself, and the elastic protrusion 521 can assist the button body 22 to reset after being pressed. In this embodiment, the back of the button body 22 is connected to an abutment post 222, and the abutment post 222 extends out of the button body 22. The protrusion 521 abuts against the abutment post 222. The abutment post 222 is used to accurately align the position of the contact point to prevent invalid operation when the button body 22 is pressed.

[0055] Preferably, the seal 5 in this embodiment is made of silicone. Silicone can resist the corrosion of various chemical media, including acids, alkalis, and salt water, so it is not easily corroded after long-term contact with liquids, thus ensuring that the seal 5 can work normally. In addition, silicone also has good electrical insulation properties, which can prevent leakage from the circuit board 21.

[0056] Optionally, the image acquisition module 3 can be any existing image acquisition module, as long as it can be installed inside the receiving cavity 13, and its specific form is not limited. Specifically, in this embodiment, the image acquisition module 3 includes a fixing bracket 31 and a camera. The fixing bracket 31 is connected to the receiving cavity 13, the camera is fixed on the fixing bracket 31 and faces the viewing window 15, and the camera is electrically connected to the circuit board 21 through wires.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
