Description

Technical Field

[0001] This utility model relates to the field of diving mask testing technology, specifically a whole-machine testing device for surface-supplied diving masks. Background Technology

[0002] The surface-supplied air diving mask is suitable for regular and saturation diving with air and mixed air. The mask is supplied with air by a diving umbilical tube or a self-contained air cylinder and can be used with dry, wet or heated diving suits as needed.

[0003] According to the publicly disclosed testing device and method for surface-supplied diving masks (Announcement No.: CN118758644B), the aforementioned application enables integrated testing of surface-supplied diving masks without disassembly. The artificial lung allows for regulation of breathing frequency and volume. The valve assembly integrates opening and closing functions as well as pressure monitoring, thereby controlling the opening and closing of the flow channel and monitoring the pressure within the channel with greater accuracy.

[0004] However, the head mold, housing, and artificial lung of the testing device are fixedly connected structures. If different sizes or models of masks need to be tested, the entire head mold needs to be replaced, rather than just the facial fitting parts, resulting in poor compatibility. Utility Model Content

[0005] The purpose of this invention is to provide a whole-machine testing device for a surface-air-supply diving mask, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a whole-machine testing device for a water-surface air-supply diving mask, comprising a housing and a head mold. A base is fixedly connected to the bottom surface of the head mold. The base is placed on the surface of the housing. A connection port is opened on the surface of the base. Multiple arrayed positioning grooves are opened on the side wall of the base. A sliding groove corresponding to the number of positioning grooves is opened on the surface of the housing. An installation component is arranged inside the sliding groove. The installation component includes a movable plate. The movable plate is slidably connected inside the sliding groove. A pressing plate is fixedly connected to one side of the movable plate. The pressing plate is inserted into the positioning groove. The other side of the movable plate is elastically connected to the inner wall of the sliding groove through a return spring. A through hole is opened on the side wall of the movable plate, and a guide rod is slidably connected in the through hole. The end of the guide rod is fixedly connected to the inner wall of the sliding groove.

[0007] Preferably, a mounting groove is formed on the surface of the housing, and a connecting component is provided inside the mounting groove. The connecting component includes a corrugated pipe, one end of which is fixedly connected to the inner wall of the mounting groove, and a connecting end is fixedly connected to the outer wall of the other end of the corrugated pipe. The connecting end is inserted into the inside of the connecting port, and the connecting end is elastically connected to the inner wall of the mounting groove by a support spring.

[0008] Preferably, the bottom surface of the connecting end is fixedly connected to multiple sets of arrayed telescopic rods, and the bottom end of the telescopic rods is fixedly connected to the inner wall of the mounting groove.

[0009] Preferably, a sealing gasket is fixedly connected to the surface of the connecting end.

[0010] Preferably, a ring is rotatably connected to the surface of the housing, and a traction plate is hinged to the surface of the ring. The end of the traction plate is hinged to the side wall of the moving plate.

[0011] Preferably, the inner wall of the positioning groove is inclined.

[0012] Compared with the prior art, this utility model provides a whole-machine testing device for a surface-air-supply diving mask, which has the following beneficial effects:

[0013] 1. This surface-mounted air-supplying diving mask whole-machine testing device can drive all moving plates and extrusion plates to simultaneously disengage from or engage with the positioning groove by rotating the ring, eliminating the need to adjust the fixing components one by one, thus simplifying the installation and disassembly process of the head mold; at the same time, the inclined surface fitting design of the positioning groove and the extrusion plate can apply downward clamping force while fixing the horizontal position of the head mold, effectively preventing the head mold from moving up and down, ensuring the relative position stability of the head mold and the mask during the testing process, and laying the foundation for the accuracy of the test data.

[0014] 2. This surface-supply type diving mask whole-machine testing device features a bellows that can adaptively extend and retract with the connection end as it moves up and down, avoiding the air circuit breakage or sealing failure problems that are easily caused by rigid connections. The telescopic rod can strictly limit the movement direction of the connection end, preventing it from deviating or tilting, and ensuring that the connection end and the head mold connection port are accurately aligned. The support spring continuously provides upward pressure to the connection end, ensuring that the sealing gasket on the surface of the connection end is always tightly attached to the inner wall of the connection port, effectively preventing air circuit leakage, ensuring the integrity of the testing air circuit, and thus improving the reliability of the whole-machine testing results of the diving mask.

Detailed Implementation

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a surface-supply type diving mask whole-machine testing device, including a housing 1 and a head mold 2. A base 21 is fixedly connected to the bottom surface of the head mold 2. The base 21 is placed on the surface of the housing 1. A connection port 22 is opened on the surface of the base 21. The head mold 2 is used to wear the diving mask, and a gas channel communicating with the connection port 22 is opened on the head mold 2. By setting the base 21, the head mold 2 can be stably placed on the surface of the housing 1. The connection port 22 cooperates with the connection end 62 in the connection component 6, so that the detection air path inside the housing 1 can enter the closed space formed by the head mold 2 and the mask. The side wall of the base 21 has multiple sets of arrayed positioning grooves 23. The inner wall of the positioning groove 23 is set to be inclined. By fitting with the inclined surface of the extrusion plate 42, the base 21 is prevented from shifting horizontally and its vertical movement is restricted, ensuring the stability of the head mold 2.

[0021] The surface of the housing 1 is provided with a number of corresponding positioning slots 23. The interior of the sliding slots 3 is provided with an installation component 4, which includes a movable plate 41. The movable plate 41 is slidably connected to the interior of the sliding slot 3. A pressing plate 42 is fixedly connected to one side of the movable plate 41 and is inserted into the interior of the positioning slot 23. The other side of the movable plate 41 is elastically connected to the inner wall of the sliding slot 3 by a return spring 43. A through hole is provided on the side wall of the movable plate 41, and a guide rod 44 is slidably connected in the through hole. The end of the guide rod 44 is fixedly connected to the inner wall of the sliding slot 3. The pressing plate 42 is adapted to the inclined surface of the positioning slot 23. The return spring 43 provides a supporting force for the movable plate 41 and the pressing plate 42 to approach the base 21. After the pressing plate 42 is inserted into the positioning slot 23, it applies downward pressure to the base 21 by fitting with the inclined positioning slot 23, thus fixing the base 21 to the surface of the housing 1.

[0022] A ring 45 is rotatably connected to the surface of the housing 1. A traction plate 46 is hinged to the surface of the ring 45, and the end of the traction plate 46 is hinged to the side wall of the moving plate 41. The ring 45 connects all the moving plates 41 through multiple sets of traction plates 46. When the ring 45 is rotated, the traction plate 46 will drive the moving plate 41 to compress the return spring 43, so that the extrusion plate 42 is separated from the positioning groove 23. This realizes the synchronous action of multiple extrusion plates 42 under single-operation control, simplifies the operation process, and facilitates the replacement of the head mold 2.

[0023] A mounting groove 5 is formed on the surface of the housing 1 to accommodate the connecting component 6. The connecting component 6, including a bellows 61, is installed inside the mounting groove 5. One end of the bellows 61 is fixedly connected to the inner wall of the mounting groove 5. An air passage interface is reserved in the mounting groove 5 to communicate with the bellows 61, allowing the air passage inside the housing 1 to lead to the connecting end 62. The connecting end 62 is fixedly connected to the outer wall of the other end of the bellows 61. The bellows 61 can move up and down with the connecting end 62 to avoid air passage breakage or sealing failure caused by rigid connection. The connecting end 62 is inserted into the inside of the connecting port 22. A sealing gasket 63 is fixedly connected to the surface of the connecting end 62. Through the docking of the connecting end 62 and the connecting port 22, the bellows 61 and the air passage of the head mold 2 are physically docked. The sealing gasket 63 ensures the sealing of the connection between the connecting end 62 and the connecting port 22.

[0024] Multiple arrays of telescopic rods 64 are fixedly connected to the bottom surface of the connecting end 62. The bottom ends of the telescopic rods 64 are fixedly connected to the inner wall of the mounting groove 5. The connecting end 62 and the inner wall of the mounting groove 5 are elastically connected by a support spring 65. The telescopic rods 64 restrict the connecting end 62 to move only in the vertical direction, preventing the connecting end 62 from shifting and failing to align with the connecting port 22. At the same time, they prevent the connecting end 62 from tilting under pressure or the action of the support spring 65, ensuring that the sealing gasket 63 can evenly fit against the connecting port 22. The support spring 65 pushes the connecting end 62 upward with its elastic force, so that the connecting end 62 is tightly inserted into the connecting port 22, providing continuous contact pressure for the sealing gasket 63 and ensuring a sealing effect.

[0025] In this utility model, when in use, firstly by rotating the ring 45 on the surface of the housing 1, the traction plate 46 hinged between the ring 45 and the moving plate 41 drives all the moving plates 41 in the slide groove 3 to slide synchronously away from the base 21. At this time, the moving plate 41 compresses the return spring 43, and the pressing plate 42 on one side of the moving plate 41 disengages from the positioning groove 23, releasing the positioning restriction on the base 21.

[0026] Subsequently, the head model 2, equipped with the diving mask to be tested, along with its base 21, is placed on the surface of the housing 1, and the connection port 22 on the base 21 is initially aligned with the connection end 62 in the mounting slot 5. During placement, the bottom surface of the base 21 contacts the connection end 62 and presses it downwards, compressing the support spring 65. Simultaneously, the telescopic rod 64 on its bottom surface retracts, ensuring that the connection end 62 moves smoothly downwards in the vertical direction and avoiding deviation.

[0027] Once the base 21 is in place, the rotating ring 45 stops rotating. At this time, the return spring 43, under the action of elastic restoring force, pushes the moving plate 41 to slide closer to the base 21. The moving plate 41 drives the pressing plate 42 to re-insert into the positioning groove 23 on the side wall of the base 21. Since the inner wall of the positioning groove 23 is inclined and matches the inclined surface of the pressing plate 42, the pressing plate 42 will exert a downward pressing force on the base 21 during the insertion process, which not only limits the horizontal displacement of the base 21, but also prevents it from moving up and down, thereby stably fixing the head mold 2 on the surface of the box 1.

[0028] Simultaneously, under the elastic restoring force, the support spring 65 pushes the connecting end 62 upward, causing it to be tightly inserted into the connecting port 22. Under the continuous pressure of the support spring 65, the sealing gasket 63 on the surface of the connecting end 62 adheres tightly to the inner wall of the connecting port 22, ensuring the sealing performance of the connection. At this time, the telescopic rod 64 remains extended, limiting the connecting end 62 and preventing it from tilting, further ensuring the uniform adhesion of the sealing gasket 63.

[0029] Finally, the test air path inside the housing 1 is introduced into the bellows 61 through the air path interface reserved in the mounting slot 5. The air is then transported through the bellows 61 to the connecting end 62, and then through the connection end 62 and the connecting port 22 into the gas channel of the head mold 2. Finally, the air enters the closed space formed by the head mold 2 and the diving mask, thus initiating the test program to test the airtightness and air supply stability of the diving mask. After the test is completed, simply rotate the ring 45 again to disengage the extrusion plate 42 from the positioning slot 23, and the head mold 2 can be removed upwards, completing one test operation. The entire process is simple to operate and effectively ensures the sealing of the test air path and the stability of the head mold 2.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
