Description

Technical Field

[0001] The utility model belongs to the field of sealing performance testing, and specifically relates to a jig for testing the sealing performance of a mobile phone. Background Art

[0002] A mobile phone is essentially a communication tool, which is a portable telephone terminal that can be used within a relatively wide range. Before leaving the factory, a mobile phone must undergo a sealing performance test to prevent a lot of dust or water vapor from entering the interior of the mobile phone due to insufficient sealing, which will affect the service life of the mobile phone.

[0003] Chinese Patent with the application number CN202320059224.4 discloses an adjustable jig for testing the sealing performance of a mobile phone, which relates to the field of mobile phone testing equipment. This jig for testing the sealing performance of a mobile phone aims to solve the technical problem that the existing jig for testing the sealing performance of a mobile phone cannot position the mobile phone, which easily leads to poor testing accuracy. This jig for testing the sealing performance of a mobile phone includes a tester body, a test bench installed at the upper end of the tester body, and an outer cover shell arranged above the test bench. A test cavity for placing a mobile phone is arranged inside the test bench. Vertical frames are symmetrically installed on the left and right sides at the upper end of the tester body. A horizontal oil cylinder is fixedly installed between the bottom ends of the vertical frames facing each other and the test bench. Two groups of positioning pieces are symmetrically arranged on the left and right sides inside the test cavity. This jig for testing the sealing performance of a mobile phone uses the method of driving the positioning pieces by a hydraulic oil cylinder to position and lock mobile phones with different structural dimensions, and prevent the mobile phone from sliding during the inflation test, resulting in fluctuations in air pressure and poor testing accuracy.

[0004] However, the above-mentioned prior art does not have a good sealing effect, resulting in large test errors. At the same time, it cannot buffer both ends of the tested mobile phone, and it is not convenient to disassemble, assemble and clean the inside of the test bench.

[0005] In view of this, the present utility model is specifically proposed. Summary of the Utility Model

Specific Embodiments

[0027] Now, the present utility model will be further described in detail in conjunction with the accompanying drawings.

[0028] Please refer to Figures 1-4As shown in the figure, in this embodiment, a mobile phone sealing test fixture is provided, which includes a tester body 1, a test bench 2 and a fixing frame 3. The bottom of the test bench 2 is fixedly installed on the top of the tester body 1, and the fixing frame 3 is fixed on the top of the tester body 1. The fixing frame 3 is located outside the test bench 2 and can fix the mobile sealing component 4. The inner wall of the top of the fixing frame 3 is fixedly installed with the mobile sealing component 4. A lower sealing ring 6 is arranged inside the test bench 2. Limiting frames 7 are fixedly arranged on both sides inside the test bench 2. A detachable fixing component 8 is clamped between the two limiting frames 7, which is convenient for quickly disassembling and assembling the detachable fixing component 8. A connecting pipe 5 is fixedly installed on the tester body 1, and the other end of the connecting pipe 5 is installed on the front side of the test bench 2. The connecting pipe 5 can connect the tester body 1 and the test bench 2 together.

[0029] One application aspect of this embodiment is as follows: The tester clamps the detachable fixing component 8 inside the test bench 2 and places the mobile phone to be tested inside the detachable fixing component 8. The detachable fixing component 8 can clamp and fix mobile phones of different models, improving the stability during mobile phone testing. Then, the mobile sealing component 4 moves downward and contacts the top of the lower sealing ring 6. The mobile sealing component 4 and the test bench 2 form a test space with good sealing effect. An air pump and a pressure sensor are arranged inside the tester body 1. The air pump can pump a certain amount of gas into the test space through the connecting pipe 5 and use the pressure sensor to detect the pressure in the test space. If the air pressure in the test space remains unchanged, it indicates that the mobile phone has good sealing performance. If the air pressure in the test space changes, it indicates that the mobile phone has poor sealing performance.

[0030] The mobile sealing component 4 includes an electric push rod 401 and an outer housing 402. The top of the electric push rod 401 is fixedly installed on the inner wall of the top of the fixing frame 3, and the top of the outer housing 402 is fixed to the bottom of the electric push rod 401. The outer housing 402 is located inside the test bench 2. An upper sealing ring 403 is fixed on the inner wall of the top of the outer housing 402, and the outer side of the upper sealing ring 403 contacts the inner wall of the test bench 2, further improving the sealing effect of the test space.

[0031] When this embodiment is in use, the stretching of the electric push rod 401 can drive the outer housing 402 to move downward into the test bench 2. The bottom of the outer housing 402 contacts the top of the lower sealing ring 6, forming a closed test space between the test bench 2 and the outer housing 402, reducing the detection error. After the detection is completed, the contraction of the electric push rod 401 can drive the outer housing 402 to move upward, facilitating the tester to take and place the mobile phone.

[0032] The detachable fixing component 8 includes a clamping block 801 and a handle 802. The clamping block 801 is clamped inside the limit frame 7. Both ends of the handle 802 are fixed to the top of the clamping block 801. An installation frame 803 is fixedly installed between the two clamping blocks 801, which facilitates the quick disassembly, installation and cleaning of the installation frame 803. Telescopic rods 804 are installed on both sides inside the installation frame 803. The other end of the telescopic rod 804 is fixed with an L-shaped support frame 805. An anti-slip pad 806 is fixed to the inner wall of the bottom of the L-shaped support frame 805. A buffer airbag 807 is fixed to one side inside the L-shaped support frame 805. A gasket 808 is arranged on the inner wall of the bottom of the installation frame 803. The gasket 808 is located below the L-shaped support frame 805. The gasket 808 can prevent the mobile phone from being damaged due to accidental dropping.

[0033] When this embodiment is in use, the tester uses the handle 802 to clamp the clamping block 801 inside the limit frame 7, so that the installation frame 803 can be quickly installed. Then, the mobile phone is placed on the top of the anti-slip pad 806. Anti-slip protrusions are arranged on the top of the anti-slip pad 806, which increases the friction between the bottom of the mobile phone and the inner wall of the bottom of the L-shaped support frame 805. The stretching of the telescopic rod 804 can drive the L-shaped support frame 805 to move, which is convenient for clamping and fixing mobile phones of different models. The buffer airbag 807 has a buffering effect on both ends of the mobile phone to prevent the mobile phone from being deformed by clamping.

[0034] The present utility model is not limited to the above embodiments. Anyone should know that structural changes made under the inspiration of the present utility model, as long as they have the same or similar technical solutions as the present utility model, all fall within the protection scope of the present utility model. The technologies, shapes and structures not described in detail in the present utility model are all well-known technologies.
