Description

Technical Field

[0001] This utility model belongs to the technical field of electronic product testing equipment, and more specifically, it relates to a mobile phone airtightness tester. Background Technology

[0002] With the development of science and technology, various industries have higher requirements for the airtightness of electronic products. Good airtightness can make electronic products have better waterproof and dustproof performance. Airtightness testing is an important means to ensure product quality and safe waterproof performance. Therefore, airtightness testing of electronic products, that is, airtightness testing of electronic product components (specifically referring to the casing of electronic products), is quite necessary. Mobile phones are electronic devices used by people every day. During the repair of mobile phones, it is also necessary to test the airtightness of mobile phones. Traditional mobile phone airtightness testing devices are bulky, the airtightness testing process is cumbersome, the airtightness testing efficiency is low, and the portability is poor.

[0003] Currently, a portable mobile phone airtightness testing device with Chinese patent publication number CN222231996U includes an air outlet pipe, a movable air pump, a first positioning block, a second positioning block, and a positioning connector mounted on the first positioning block. The air outlet pipe is connected to the positioning connector and the movable air pump at its two ends respectively. An adjusting screw with an adjusting knob at one end is hinged to the second positioning block, and the other end of the adjusting screw is screwed to the first positioning block. By inserting the positioning connector into the mobile phone SIM card tray slot and rotating the adjusting knob, the mobile phone is clamped between the first and second positioning blocks. The device is then used to test the airtightness of a mobile phone by moving the air pump. The pump inflates the phone through the outlet pipe, and the pressure display screen shows the change in air pressure to determine whether the phone passes the airtightness test. Although the above-mentioned testing device improves the portability of the device, it can only be used for the airtightness test of the phone, which is a single function. It still needs to be powered by electronic equipment, resulting in high usage, maintenance and replacement costs. In addition, because the air holes and outlet pipe of the positioning connector are exposed, the outlet pipe is prone to bending and damage, resulting in air leakage and dust accumulation on the air holes. This can lead to blockage of the air holes or the introduction of dust from the air into the phone during the test, affecting the airtightness test results. Utility Model Content

The purpose of this system is to prevent the existing air supply pipe from being damaged due to exposure, which would affect the testing results. The pressure gauge is used to observe the pointer changes; if the pointer slowly returns, the airtightness is acceptable; if the pointer quickly falls back, the airtightness is unacceptable. After testing, the valve on the vent pipe is opened to release air. The support rod and angle adjustment device are then used to adjust the angle between the support rod and the base, thus realizing the function of a phone holder. The entire system integrates storage, support, and dust protection, preventing air leakage due to the easily bent and damaged exposed air supply pipe, and preventing dust from entering the phone through the vent during testing. It has the advantages of being multifunctional, reducing maintenance and replacement costs, and ensuring airtightness testing results. Attached Figure Description

Detailed Implementation

[0027] To explain the technical content, objectives, and effects of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings. It should be noted that the terms "upper" and "lower" used in the following description refer to the attached drawings. Figure 2 The direction in the middle, the words "bottom" and "top" refer to the attached Figure 2 The direction towards the geometric center of a specific component.

[0028] Reference Figures 1 to 5 The first embodiment provided by this utility model is as follows:

[0029] A mobile phone airtightness tester includes a base 1. Pressure gauges 2 and manual inflation devices 8 are respectively installed on opposite sides of the base 1. The base 1 contains a first inflation channel 3 and a second inflation channel 4. The two ends of the first inflation channel 3 are connected to the outlet of the manual inflation device 8 and the inlet of the pressure gauge 2, respectively. A detection block 5 is located on one side of the upper end of the base 1. An inflation hole 6 is opened on one side of the detection block 5, and the inflation hole 6 is connected to the first inflation channel 3 via the second inflation channel 4. The other side of the upper end of the base 1 is connected along both sides of the base 1. A clamping block 7 is slidably connected in the direction of the connection line. A spring 31 is connected between the clamping block 7 and the base 1 to push the clamping block 7 to slide towards the detection block part 5. A dustproof box 9 is detachably connected to one side of the detection block part 5. The dustproof box 9 has a storage cavity 10 for storing detection and maintenance auxiliary tools. A support rod 28 and an angle adjustment component for adjusting the angle between the support rod 28 and the base 1 are hinged around the bottom of the base 1 around the connection line between the opposite sides of the base 1. A groove 11 is opened at the bottom of the base 1 for the support plate 27 and the angle adjustment component to be stored.

[0030] Furthermore, a support part 12 for supporting the mobile phone is provided on one side of the upper end of the base 1. The support part 12 is located between the detection block part 5 and the clamping block 7. The base 1, the support part 12 and the detection block part 5 are integrally formed. The clamping block 7 is connected to a set of guide rods 13, all of which are T-shaped. A guide groove 14 is provided on the side of the support part 12 away from the detection block part 5 for the guide rods 13 to slide in the direction of the detection hole. A retaining ring part 15 is provided at the opening of the guide groove 14. The spring 31 is located in the guide groove 14 and is sleeved on the outside of the vertical end of the guide rod 13. The spring 31 is located between the retaining ring part 15 and the horizontal end of the guide rod 13.

[0031] Furthermore, the dust box 9 includes a set of internal threaded sleeves 16 and a box body 17 sandwiched between the clamping block 7 and the detection block 5. One side of the box body 17 has a sealing groove 18 for sealing the inflation hole 6. A side dust cover 20 is detachably connected to one side of the box body 17. A first sealing ring 19 is connected to the outside of the groove of the sealing groove 18, which contacts one side of the detection block 5 or the side dust cover 20. An upper dust cover 21 for sealing the storage cavity 10 is detachably connected to the upper end of the box body 17. Connecting rings 22 are connected to both sides of the detection block 5. Threaded rods 23 with nuts and threaded to the internal threaded sleeves 16 are threadedly connected to the connecting rings 22. A set of internal threaded sleeves 16 are respectively connected to both sides of the box body 17. The storage cavity 10 has a mobile phone needle groove 24, a sealing sticker groove 25, and a cleaning cloth groove 26. The storage cavity 10 may also have a placement groove for storing the side dust cover 20 (not shown in the figure, the same throughout the text).

[0032] As described above, the side dust cover 20 and the top dust cover 21 provide dust protection for the sealing groove 18 and the storage cavity 10 when they are not in use. When it is necessary to use the sealing groove 18 or to retrieve items from the storage cavity 10, the corresponding side dust cover 20 and top dust cover 21 can be detached and opened. The detachable connection between the side dust cover 20 and the top dust cover 21 and the box body 17 can be a plug-in or snap-fit ​​connection, but is not limited to these two methods; other detachable connection methods are also acceptable. A cleaning cloth tray 26 is provided to hold a cleaning cloth. To clean the phone or the testing block 5 before or after testing, the cleaning cloth can be a disposable cloth or a reusable cleaning cloth. After use, the user can wash and dry it. When it is necessary to remove the box 17, rotate the nut and unscrew the threaded rod 23 out of the inner thread sleeve 16. To ensure the connection stability of the dust box 9, straps can also be provided on both sides of the bottom of the box 17 to tie the box 17 to the support part 12 and the base 1 (not shown in the figure, the same throughout the text). The two straps are detachably connected by Velcro.

[0033] Furthermore, the angle adjustment component is a support plate 27. One end of the support plate 27 and one end of the support rod 28 are both hinged to the bottom of the base 1. The support plate 27 and the support rod 28 are located on the other opposite sides of the base 1. A connecting rod 30 is connected between the other ends of the support rod 28. The support plate 27 has several positioning grooves 29 for placing the connecting rod 30 along its two ends. The upper surface of the support plate 27 has a clearance groove 32 for placing the support rod 27 and the connecting rod 30.

[0034] As can be seen from the above description, when the whole is used for mobile phone support function and the angle between the support rod 28 and the base 1 needs to be adjusted, simply rotate the support rod 28 and place the other end of the support rod 28 into the corresponding positioning groove 29 to achieve the function of adjustable angle between the support rod 28 and the bottom surface of the base 1; through the clearance groove 32, it is easy for the support plate 27 and the support rod 28 to be completely closed in the groove 11.

[0035] Furthermore, the manual inflation device 8 is a squeeze-type inflatable ball. The air outlet b of the squeeze-type inflatable ball is connected to one end of the first inflation channel 3 in a sealed manner through an air pipe connector. Both the air inlet a and the air outlet b of the squeeze-type inflatable ball are equipped with one-way valves (not shown in the figure, the same throughout the text). The air outlet b of the squeeze-type inflatable ball is connected to a vent pipe 33 with a valve. Alternatively, the manual inflation device 8 can also be an air pump, but a squeeze-type inflatable ball is preferred. The squeeze-type inflatable ball is a spherical object with a cavity made of silicone or rubber, which is a common type of squeeze-type inflatable ball.

[0036] As described above, when manual inflation is required, the operator simply needs to hold and squeeze the hand-operated inflation ball, then flatten it, and then release it. During the release process, the hand-operated inflation ball will spring back to its spherical shape. By repeatedly flattening and releasing, inflation can be achieved into the first inflation channel 3. Since both the inlet and outlet ends of the hand-operated inflation ball are equipped with one-way valves, outside air continuously enters the hand-operated inflation ball and enters the inflation channel along the air pipe connector. Through the inflation channel, it enters the pressure gauge 2 and the detection block 5 respectively. The gas in the detection block 5 enters the SIM card tray through the inflation hole 6. After the test is completed, the operator opens the valve on the vent pipe 33, and the excess gas in the second inflation channel 4 and the pressure gauge 2 is discharged from the first inflation channel 3 through the vent pipe 33.

[0037] Furthermore, in another embodiment of this example: a protective cover 34 is fitted on the outside of the pressure gauge 2, a housing 35 is connected to the bottom of the base 1 and the pressure gauge 2, the bottom inner side of the protective cover 34 is threadedly connected to the outer side of the housing 35, and a hanging ring 36 with a hanging rope is provided on the top of the protective cover 34.

[0038] As can be seen from the above description, by setting up a protective cover 34, the pressure gauge 2 is prevented from being damaged by external forces when not in use, thus protecting the protective cover 34. The protective cover 34 is threadedly connected to the housing 35, which facilitates the disassembly of the protective cover 34. By setting a hanging rope and a hanging ring 36 on the top of the protective cover 34, it is convenient for the user to wear the whole thing on their body.

[0039] Example 2 differs from Example 1 in that, as Figure 6 and Figure 7 As shown, a set of guide rods 13 are connected to a connecting plate 37 at their vertical ends. The connecting plate 37 is connected to a screw 38 with a nut. The bottom of the clamping block 7 is provided with a first threaded hole 39 for the screw 38 to pass through. An extension plate 41 is provided in the storage cavity 10. The extension plate 41 is provided with a second threaded hole 40 for the screw 38 to pass through and communicate with the first threaded hole 39. The screw 38 is threaded with a nut that abuts against the side of the connecting plate 37 away from the support part 12. The support part 12 is provided with a clearance groove 42 for the screw 38 to pass through. In this embodiment, in order to avoid the manual inflation device 8 from affecting the use of the extension plate 41, there is a sufficient distance between the top of the manual inflation device 8 and the bottom of the support part 12 for the user to use the manual inflation device 8 manually.

[0040] As described above, when it is necessary to perform airtightness testing on tablet computers or wide foldable screen phones, the screw 38 can be unscrewed from the clearance groove 42 first, and then the extension plate 41 can be taken out from the storage cavity 10. The screw 38 first passes through the first threaded hole 39 of the clamping block 7, then passes through the second threaded hole 40 of the extension plate 41, and then passes through the connecting plate 37 and the nut again. After that, the screw 38 passes through the clearance groove 42 until the screw 38 is screwed into the extension plate 41 and the clamping block 7 clamped between the connecting plate 37 and the nut of the screw 38. Finally, the nut is tightened. This allows for airtightness testing of larger electronic devices such as tablet computers or wide foldable screen phones, thereby further improving the overall applicability.

[0041] Example 3 differs from Example 1 in that, as Figure 8 As shown, the detection block 5 includes a fixed block 43 and a detection head 44. The fixed block 43 is mounted on the base 1, and the detection head 44 is detachably mounted on the fixed block 43. An air inlet 6 is located on the detection head 44. The part of the detection head 44 that contacts the mobile phone is made of a flexible material, such as silicone. This design is to prevent the detection block 5 from damaging the mobile phone and to ensure a tight fit with the surface of the mobile phone, preventing air leakage and stabilizing the airtightness detection effect. The detection head 44 and the fixed block 43 are detachably connected, and a more suitable detection head 44 can be replaced according to the edge type of the mobile phone to be tested.

[0042] Example 4 differs from Example 1 in that, as Figure 9 and Figure 11 As shown, the detection block 5 and the base 6 are detachably and sealed. This detachable and sealed connection can be achieved by connecting a threaded connector (not shown in the figure) at the bottom of the detection block 5 to a threaded hole in the base 6. This threaded hole communicates with the second inflation channel 4. To ensure airtightness, a sealing gasket or sealing ring can be placed between the connector of the detection block 5 and the base 6. This is not limited to the detachable and sealed connection method described above; any method that achieves a detachable and sealed connection, such as snap-fit ​​with a sealing ring, is acceptable. The base 6 is a detachable, split structure set along the central axis of the first inflation channel 3. The first inflation channel 3 contains... The device is equipped with a first air pipe 45 and a second air pipe 46. One end of the first air pipe 45 is connected to the air outlet of the manual inflation device 8, and the other end is connected to a three-way connector 47. One end of the three-way connector 47 is connected to the pressure gauge 2 through the second air pipe 46. A third air pipe 48 is provided in the second inflation channel 4. One end of the third air pipe 48 is connected to the other end of the three-way connector 47, and the other end is connected to the bottom of the detection block 5 through an air pipe connector. The air pipe connector can be fixedly or detachably connected to the connector at the bottom of the detection block 5. An air chamber (not shown in the figure) is provided in the detection block 5, which is connected to the inflation hole 6 and the second inflation channel 4.

[0043] In this embodiment, the first air tube 45 and the second air tube 46 are hidden inside the first inflation channel 3 and the second inflation channel 4 to prevent the two air tubes from being exposed and thus easily damaged and leaking air, thereby protecting the two air tubes. The split base 1 in this embodiment can be detachably connected by screws. It is not limited to this detachable connection method. Other methods such as snap-fit ​​are also acceptable, as long as the detection block 5 and the base 1 can be detached and separated, so that the first air tube 45, the second air tube 46 and the third air tube 48 can be installed in the corresponding channels.

[0044] In summary, compared with the prior art, this utility model has the advantages of multifunctionality, low maintenance and replacement costs, and guaranteed airtightness detection effect. Working principle: First, remove the dustproof box 9 from the detection block 5, open the upper dustproof cover 21, remove the phone pin from the storage cavity 10, and use the phone pin to remove the SIM card tray of the phone. Then, pull the clamping block 7 away from the detection block 5. Next, place the phone on the support part 12, and insert one side of the detection block into the phone's SIM card tray slot. Release the clamping block 7. Under the rebound force of the spring 31, the clamping block 7 slides in the guide groove 14 via the guide rod 13 towards the detection block 5 until the clamping block 7 and the detection block 5 together firmly clamp the phone. Compared with the existing rotary adjusting screw clamping, this embodiment clamps faster and more effectively, avoiding over-clamping. Then, manually squeeze and release the inflatable balloon repeatedly until the air... The airflow enters the detection block 5 through the first inflation channel 3 and the second inflation channel 4, and then enters the inside of the phone through the inflation hole 6 of the detection block 5. Observe the change of the pointer on the pressure gauge. If the pointer of the pressure gauge slowly returns, the air tightness is qualified. If the pointer of the pressure gauge falls back quickly, the air tightness is unqualified. To ensure the accuracy of the test or to check for leaks, the sealing sticker in the storage cavity 10 can be used to seal the earpiece hole, headphone hole, etc. in sequence or together, and then the air tightness is retested. After the test is completed, open the valve on the vent pipe 33 to vent the air, and re-detachably clamp the dust box 9 between the detection block 5 and the clamping block 7. Use the sealing groove 18 and the first sealing ring 19 to seal the inflation hole 6 to prevent dust in the air from entering the air inlet. When the phone stand function is needed, open the support rod 28 and the angle adjustment component, and use the angle adjustment component to adjust the angle between the support rod 28 and the base 1.

[0045] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
