Description

Technical Field

[0001] This utility model relates to the field of testing equipment, and in particular to a device for testing the water tightness of a high-sealing water filter cup. Background Technology

[0002] High-sealing water filter cups are widely used in outdoor adventures, emergency rescue, and home water purification. Their water tightness directly affects the filtration effect and safety of use. As a key device to ensure the quality of water filter cups, the water tightness testing device ensures that the water filter cups do not leak under different pressure environments through scientific testing methods and precise control technology. The sealed testing chamber is made of corrosion-resistant material and has high pressure resistance. It is used to place the water filter cup to be tested and form a closed space. The inner wall of the chamber is smooth to avoid scratching the surface of the water filter cup. It is customized according to the shape and size of the water filter cup. It can quickly clamp and position through pneumatic or electric drive to ensure that the water filter cup and the chamber are sealed and fit together, preventing additional leakage points during the testing process. The pressure interface and pipeline include air inlet, air outlet, pressure sensor interface, etc. The pipeline uses high-pressure hoses and the joints use precision seals to reduce leakage errors. The water cup airtightness testing platform mainly includes a testing platform base, a testing chamber, a chamber sealing cover, a water cup clamping device, and a pressurizing pump body. The testing platform base supports the entire device. The testing chamber is fixed to the top of the base and contains a water cup clamping device composed of multiple clamping rods. These rods are connected by components such as sliding rods, connecting rod platforms, and connecting rod fixing platforms. Springs are installed on the sliding rods, causing the clamping rods to tend to converge towards the center, thus clamping and fixing the water cup. The chamber sealing cover is mounted on the testing platform via a shaft. At the top of the chamber, the main body of the pressurizing pump is installed on the front of the outer wall of the test chamber. Its pressurizing pipe runs through the inside of the test chamber. The sealed water cup is placed upside down inside the test chamber and clamped and fixed by the water cup clamping device to prevent the water cup from tipping over due to the buoyancy of the water. Then, water is passed into the test chamber until the water covers the water cup's sealing cover. The chamber's sealing cover is then closed, and the main body of the pressurizing pump pressurizes the inside of the test chamber. After a period of time, the test chamber cover is opened to check whether there is any water ingress in the cup, thus realizing the test of the water cup's sealing performance. Problems with existing clamping mechanisms: In the design of existing water filter cup water tightness testing devices, there are common problems such as unstable power output, insufficient adaptability, and poor operational stability, which directly affect the testing efficiency and accuracy. Existing clamping mechanisms mostly use spring drive or manual adjustment to achieve clamping action. The elasticity of the spring gradually decreases with the number of uses, resulting in a continuous decrease in the clamping force on the water filter cup, making it impossible to maintain a stable clamping effect for a long time. Especially in high-pressure testing environments, the water filter cup is prone to displacement or shaking due to insufficient clamping force. Therefore, a high-sealing water filter cup water tightness testing device is proposed to solve the above problems. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a high-sealing water filter cup water tightness testing device, which aims to improve the problems of unstable power output, insufficient adaptability and poor operation stability of the clamping mechanism in the prior art, which affect the testing efficiency and accuracy.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a water tightness testing device for a high-sealing water filter cup, comprising a water tank, a clamping mechanism fixedly connected to the inner side of the water tank, a support base fixedly connected to the top of the water tank, and a disassembly and adjustment mechanism fixedly connected to the bottom of the support base. The clamping mechanism includes a pneumatic cylinder, the bottom of which is fixedly connected to the inner side of the water tank, a fixing component fixedly connected to the top of the pneumatic cylinder, a moving plate fixedly connected to the driving end of the pneumatic cylinder, a transmission rod slidably connected to the outer side of the moving plate, a sliding rod slidably connected to the top of the transmission rod, a slider fixedly connected to the outer side of the sliding rod, a slide rail slidably connected to the bottom of the slider, a clamping arm fixedly connected to the top of the slider, and a placement platform fixedly connected to the bottom of the clamping arm. As a further description of the above technical solution: The disassembly and adjustment mechanism includes a second pneumatic cylinder. The bottom of the second pneumatic cylinder is fixedly connected to the top of the support base. A pipe is fixedly connected to the drive end of the second pneumatic cylinder. A locking pin is slidably connected to the outside of the pipe. A spring is slidably connected to the inside of the locking pin. A steel ball is slidably connected to the inside of the pipe. A replacement air nozzle is slidably connected to the inside of the pipe. A limit ring is fixedly connected to the bottom of the pipe. As a further description of the above technical solution: The fixing component includes a base, the outer side of which is fixedly connected to the inner wall of the pool, a support fixedly connected to the top of the base, and a fixing plate fixedly connected to the top of the support. As a further description of the above technical solution: The outer side of the steel ball is slidably connected to the outer side of the replacement air nozzle, and the outer side of the steel ball is slidably connected to the inner side of the locking pin. As a further description of the above technical solution: The inner side of the spring is slidably connected to the outer side of the pipe, and the outer side of the limiting ring is slidably connected to the inner side of the locking pin. As a further description of the above technical solution: The bottom of the movable plate is fixedly connected to the top of the base, and the top of the movable plate is fixedly connected to the bottom of the fixed plate.

[0005] This utility model has the following beneficial effects: 1. In this utility model, the pneumatic cylinder in the clamping mechanism serves as the core power source, driving the linkage structure to work. The movement of the moving plate is transmitted to the transmission rod that is slidably connected to it, causing the transmission rod to slide. This, in turn, transmits the power to the sliding rod that is slidably connected at the top, causing the sliding rod to move synchronously. The movement of the sliding rod causes the slider that is fixedly connected to the outside to slide smoothly along the slide rail. The clamping arm at the top of the slider opens and closes under the drive of the slider, thereby achieving a stable clamping effect on the water filter cup.

[0006] 2. In this utility model, in the disassembly and adjustment mechanism, the pneumatic cylinder 2 acts as a structural component for the adjustment action. The locking pin, which is slidably connected to the outside of the pipe, cooperates with the spring, which is slidably connected to the inside. The locking pin can be engaged in a preset position under the action of the spring force to lock the pipe and related components. When the position needs to be adjusted, the external force can make the locking pin overcome the spring force and slide, releasing the locking state. This allows the adjustment action to achieve precise control, and the position is firmly and reliably fixed after adjustment. This solves the problems of easy loosening of components, unstable position, and cumbersome operation during the adjustment process. Attached Figure Description

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0010] Reference Figures 1 to 3 This utility model provides an embodiment of a high-sealing water filter cup water tightness testing device, including a water tank 1. The water tank 1 provides a water storage space for the testing process, allowing the water filter cup to be completely immersed in water to observe the sealing condition. A clamping mechanism 2 is fixedly connected to the inner side of the water tank 1. The clamping mechanism 2 can stably fix water filter cups of different specifications, preventing the water filter cups from shaking during testing and affecting the accuracy of the test. A support base 3 is fixedly connected to the top of the water tank 1. The support base 3 provides a stable installation support for the disassembly and adjustment mechanism 4 above, ensuring the stability of the mechanism during operation. The disassembly and adjustment mechanism 4 is fixedly connected to the bottom of the support base 3. The disassembly and adjustment mechanism 4 can flexibly adjust the relative position with the water filter cup, facilitating the testing operation of water filter cups of different heights and sizes. The clamping mechanism 2 includes a pneumatic cylinder 21, which provides power output for the operation of the clamping mechanism 2, driving the relevant components to complete the clamping action.

[0011] The bottom of the pneumatic cylinder 21 is fixedly connected to the inside of the water tank 1, ensuring a firm installation and stable power output. A fixing component 22 is fixedly connected to the top of the pneumatic cylinder 21, which helps to fix the water filter cup and enhances the stability of the clamping. A moving plate 23 is fixedly connected to the drive end of the pneumatic cylinder 21, which can move under the drive of the pneumatic cylinder 21. A transmission rod 24 is slidably connected to the outside of the moving plate 23, which can convert the movement of the moving plate 23 into its own sliding, thus realizing power transmission. A sliding rod 25 is slidably connected to the top of the transmission rod 24, which can slide under the drive of the transmission rod 24, further transmitting power to the clamping component. A slider 26 is fixedly connected to the outside of the sliding rod 25, which can move together with the sliding rod 25 to provide moving support for the clamping arm 28. A slide rail 27 is slidably connected to the bottom of the slider 26, which provides guidance for the movement of the slider 26 and ensures that the slider 26 moves smoothly.

[0012] A clamping arm 28 is fixedly connected to the top of the slider 26. The clamping arm 28 opens and closes under the action of the slider 26, thereby clamping or releasing the water filter cup. A placement platform 29 is fixedly connected to the bottom of the clamping arm 28. The placement platform 29 provides a support surface for the water filter cup, so that the water filter cup remains in a stable placement state during testing.

[0013] Reference Figure 1 , Figure 2 and Figure 4 The disassembly adjustment mechanism 4 includes a second pneumatic cylinder 41. The second pneumatic cylinder 41 serves as the power source for adjustment and can achieve precise control of the adjustment action through telescopic drive. The bottom of the second pneumatic cylinder 41 is fixedly connected to the top of the support base 3. This fixing method ensures that the second pneumatic cylinder 41 can maintain a stable support state during operation, providing a solid foundation for the adjustment operation. The drive end of the second pneumatic cylinder 41 is fixedly connected to a pipe 42. The pipe 42 serves as a carrier for power transmission and component connection, and can effectively transmit the driving force of the second pneumatic cylinder 41. A locking pin 43 is slidably connected to the outside of the pipe 42. The locking pin 43 can slide on the outside of the pipe 42, thereby realizing the locking and unlocking functions of related components and ensuring the position is fixed during the adjustment process. A spring 44 is slidably connected to the inside of the locking pin 43. The elasticity of the spring 44 can make the locking pin 43 automatically reset when no external force is applied, ensuring the reliable realization of the locking function.

[0014] The pipe 42 has a sliding connection of steel balls 45 inside. When the steel balls 45 slide inside the pipe 42, they can reduce the friction between the parts and make the movement of the relevant parts smoother and more flexible. The pipe 42 has a sliding connection of a replacement air nozzle 46 inside. The sliding connection design between the replacement air nozzle 46 and the inside of the pipe 42 facilitates the quick replacement and maintenance of the air nozzle and improves the ease of use of the equipment. The bottom of the pipe 42 is fixedly connected to a limit ring 47. The limit ring 47 can limit the movement range of the sliding parts inside the pipe 42 and prevent the parts from deviating from the preset trajectory due to excessive sliding.

[0015] Reference Figure 1 , Figure 3 and Figure 4 The fixing component 22 includes a base 221, the outer side of which is fixedly connected to the inner wall of the pool 1. This connection method allows the base 221 to be firmly anchored inside the pool 1, providing a solid foundation support for the entire fixing component 22 and ensuring that subsequent components will not shift or shake due to external forces after installation. A support 222 is fixedly connected to the top of the base 221. Through the fixed connection between the base 221 and the support 222, the support 222 can be stably supported, placing the support 222 at a preset working height and providing a suitable installation platform for the components connected to its top. This ensures that the positional relationship between the components meets the design requirements. A fixing plate 223 is fixedly connected to the top of the support 222. The support 222 supports and fixes the fixing plate 223, allowing the fixing plate 223 to remain horizontal and stable. This provides a flat and firm reference surface for components installed above or penetrating it, which is conducive to the coordinated work of the components.

[0016] The outer side of the steel ball 45 is slidably connected to the outer side of the replacement air nozzle 46. This slidable connection allows the steel ball 45 to move flexibly on the outer side of the replacement air nozzle 46, facilitating accurate engagement of the steel ball 45 with the locking pin 43 during subsequent locking operations, thus effectively locking or unlocking the replacement air nozzle 46. The outer side of the steel ball 45 is slidably connected to the inner side of the locking pin 43. The sliding of the steel ball 45 on the inner side of the locking pin 43 transmits force. When the locking pin 43 moves, its position can be adjusted by the rolling of the steel ball 45, thereby achieving the locking function of the relevant components and ensuring that the components do not accidentally disengage during operation. The inner side of the spring 44 is slidably connected to the outer side of the pipe 42. The spring 44 slides with the pipe 42 as a guide, ensuring that the spring 44 does not shift laterally during extension and retraction, and that the spring 44 can stably apply elastic force along the axial direction of the pipe 42, providing a continuous and stable force for the reset or locking of the relevant components.

[0017] The outer side of the limiting ring 47 is slidably connected to the inner side of the locking pin 43. The sliding of the limiting ring 47 on the inner side of the locking pin 43 can limit the movement range of the locking pin 43, preventing the locking pin 43 from moving excessively and exceeding the preset working position, thereby ensuring the normal operation of the entire locking mechanism. The bottom of the moving plate 23 is fixedly connected to the top of the base 221. The moving plate 23 obtains stable support through its fixed connection with the base 221, enabling it to stand vertically and provide guidance or limitation for subsequent moving parts, ensuring that the moving parts move according to the predetermined trajectory. The top of the movable plate 23 is fixedly connected to the bottom of the fixed plate 223. The upper and lower ends of the movable plate 23 are fixed to the base 221 and the fixed plate 223 respectively, which further enhances the structural rigidity of the entire fixed assembly 22, making the base 221, the movable plate 23 and the fixed plate 223 form a stable overall frame, improving the component's resistance to deformation. The bottom of the slide rail 27 is fixedly connected to the top of the support 222. The fixed connection between the slide rail 27 and the support 222 ensures the installation stability of the slide rail 27, enabling the slide rail 27 to provide precise guidance for the sliding parts.

[0018] The bottom of the slide rail 27 is fixedly connected to the top of the fixed plate 223. The slide rail 27 is also fixed to both the support 222 and the fixed plate 223, further reinforcing the installation of the slide rail 27. This ensures that the slide rail 27 can withstand the force brought by the sliding components, preventing it from loosening or deforming during long-term use and maintaining the stability of the guiding function. The outer side of the transmission rod 24 is slidably connected to the inside of the fixed plate 223. The transmission rod 24 slides with the fixed plate 223 as support. The fixed plate 223 provides stable guidance for the transmission rod 24, enabling it to move accurately along the preset direction, thereby effectively transmitting power and realizing the linkage operation between various components. The bottom of the placement platform 29 is fixedly connected to the top of the fixed plate 223. The placement platform 29 obtains stable support through its fixed connection with the fixed plate 223, allowing it to smoothly support the items or components to be placed. This ensures that the placed objects will not easily shake or fall during operation, ensuring the safety and stability of the operation.

[0019] Working principle: In the water tightness testing process of the high-sealing water filter cup, the clamping mechanism 2 inside the water tank 1 is the core component for achieving precise fixation. The pneumatic cylinder 21 at the bottom of the mechanism serves as a power source, which can stably output driving force to drive the moving plate 23 to complete the up-and-down reciprocating motion. This reciprocating motion is achieved through a clever mechanical transmission structure. The transmission rod 24 has a groove inside, and the outer edge of the moving plate 23 is precisely embedded in the groove at the bottom of the transmission rod 24, forming a tight sliding fit. When the moving plate 23 moves up and down under the drive of the pneumatic cylinder, the transmission rod 24 will move synchronously, realizing the longitudinal transmission of power. After the power is transmitted to the top, the sliding rod 25 in the groove of the transmission rod 24 will be displaced, thereby driving the connected slider 26 to slide smoothly on the surface of the slide rail 27. The slide rail 27 adopts a high-precision linear guide design to ensure that the slider 26 moves without jamming or deviation. As the slider 26 slides laterally, the clamping arm 28 connected to its top will complete the opening and closing action.

[0020] When the slider 26 slides inward, the clamping arms 28 move closer together, forming a stable clamp on the filter cup on the placement platform 29. This ensures that the filter cup will not shift due to water flow impact or air pressure changes during the testing process, providing a reliable fixed foundation for subsequent water tightness testing. For testing needs of filter cups with different diameters, a disassembly and adjustment mechanism 4 is specially designed on the top of the equipment. When the air nozzle 46 needs to be replaced, the operator only needs to slide the locking pin 43 upward. At this time, the spring 44 inside the locking pin 43 is subjected to axial compression, causing elastic deformation. The positioning end of the locking pin 43 moves away from the steel ball 45. After losing the radial constraint of the locking pin 43, the steel ball 45 will pop outward under the action of the inclined surface of the outer wall of the air nozzle, releasing the fixed limit on the replacement air nozzle 46. At this time, the old air nozzle can be easily pulled out. The operator can select a matching new air nozzle for installation according to the diameter of the filter cup to be tested. This design achieves rapid replacement and precise adaptation of the air nozzle, effectively improving the equipment's testing compatibility and operational convenience for filter cups of different specifications.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
