[0001] The invention belongs to the technical field of earphone plugs, and in particular relates to a testing device for earphone plugs with fluororubber surface protection UV glue and protective oil. Background Art

[0002] Earphones are a widely used electronic product. The part of the earphones on the market that comes into closest contact with the human body is the earphone plug. The size and shape of the earphone plug directly affect the user experience.

[0003] Earphone plugs are usually made of soft materials. However, due to the different shapes of users' ear cavities, even using soft materials still has certain limitations, such as not being able to match the shape of the ear cavity well, causing pressure on the ear cavity, and causing a feeling of squeezing and soreness. Therefore, a fluororubber surface protected UV glue protective oil earphone plug has been developed. It uses the property of UV glue to cure under ultraviolet light, so that the earphone plug can change the curing according to the shape of the ear cavity. In order to understand its actual application effect, it needs to be tested.

[0004] Therefore, it is necessary to invent a fluororubber surface protection UV glue protection oil earphone plug testing device to solve the above problems. Summary of the invention

[0005] In view of the above problems, the present invention provides a testing device for fluororubber surface protection UV glue protective oil earphone plugs to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions: a testing device for fluororubber surface protection UV glue protection oil earphone plugs, comprising a base, the top of the base is sealed and clamped with a transparent cover;

[0007] Inside the transparent cover, a test tube structure and a vertical plate are fixedly installed on both sides of the top of the base respectively;

[0008] A polarization structure is fixedly installed inside the test cylinder structure, an adjustment structure is fixedly installed on the top of the test cylinder structure facing the vertical plate, and an end of the adjustment structure away from the test cylinder structure is used for fixed connection with the earphone plug body;

[0009] The side of the vertical plate facing the test tube structure is slidably connected with a mounting plate, the top of the mounting plate is snap-fitted with a simulation test board, and the side of the simulation test board facing the test tube structure is provided with a simulation ear canal matching the earphone plug body.

[0010] Optionally, the test cylinder structure includes an outer cylinder, the middle part of the inner side and the top end of the inner side of the outer cylinder are both fixedly connected with elastic soft rings, and the outer cylinder is fixedly embedded with an inner cylinder through the elastic soft ring; the top end of the inner cylinder extends out of one side of the top surface of the outer cylinder and is fixedly connected to the adjustment structure.

[0011] Optionally, the adjustment structure includes an outer rod fixedly connected to the outer side of the inner tube, and a gear rod is slidably inserted inside the outer rod; an end of the gear rod away from the inner tube passes through an end surface of the outer rod away from the inner tube, and is fixedly connected to a connecting rope; an end of the connecting rope away from the gear rod is fixedly connected to a mounting rod matching the earphone plug body, and the top end of the gear rod is meshedly connected to a gear rod for adjusting the penetration length of the gear rod, and one end of the gear rod passes through the outer side wall of the outer rod.

[0012] Optionally, the polarization structure includes a motor, a top end of the motor is fixedly connected to an eccentric block, and one side of the eccentric block is in contact with the inner side of the inner cylinder.

[0013] Optionally, a metal soft light board is fixedly mounted on one side of the top of the base, and an ultraviolet lamp is fixedly mounted on one side of the metal soft light board facing the earphone plug body.

[0014] Optionally, an exhaust pipe is fixedly opened on the other side of the top of the base, and one end of the exhaust pipe passes through the outside of the base and is connected to an external exhaust device.

[0015] Optionally, an inner cavity structure for filling fluororubber surface protection UV glue protection oil is opened inside the earphone plug body.

[0017] Optionally, the simulation test plate is a silicone plate, and the silicone plate is filled with reinforcing ribs prepared to simulate the shape of auricular cartilage.

[0018] Technical effects and advantages of the present invention:

[0019] When the present invention is used, after the earphone plug body is installed on the adjustment structure, the earphone plug body is placed in the simulated ear canal of the simulation test board, and then the ultraviolet lamp is turned on to irradiate the earphone plug body, so that the earphone plug body is cured and changed according to the shape of the simulated ear canal. After the curing is completed, the height of the simulation test board can be adjusted through the installation plate to make the connecting rope present a desired angle. After the adjustment is completed, the polarization structure is started, and the polarization structure knocks the test tube structure through the eccentric block to make the inner tube vibrate. The inner tube drives the adjustment structure to pull the connecting rope, simulating the pulling force of the earphone plug body in normal use, and then testing the anti-pulling function of the earphone plug body. After the test is completed, the earphone plug body is taken out for observation, and the conditions of the earphone plug body irradiated with the ultraviolet lamp for different times are observed, so as to obtain the optimal ultraviolet irradiation time of the earphone plug body.

[0020] Since the earphone plug body of the present invention has an inner cavity structure and is injected with high-comfort fluororubber surface protection UV glue protection oil, oil leakage may occur if the sealing process is not done well during processing. Therefore, before testing the anti-pull function, the earphone plug body and the mounting rod are first put into the simulated ear canal, and then the transparent cover is sealed and engaged. The air in the transparent cover is then extracted through the exhaust pipe to put the inside of the transparent cover in a low-pressure state. After a period of time, the transparent cover is opened and the earphone plug body is removed to observe whether there is oil leakage, so as to calculate the product yield.

[0030] The present invention provides Figure 1-4 The shown device is a test device for earphone plugs with fluororubber surface protection UV glue and protective oil, comprising a base 1, a test tube structure 2 is fixedly connected to one side of the top of the base 1, a polarization structure 3 is fixedly installed inside the test tube structure 2, an adjustment structure 4 is fixedly installed on the top of one side of the test tube structure 2, an earphone plug body 5 is fixedly connected to one end of the adjustment structure 4, a vertical plate 6 is fixedly installed on one side of the test tube structure 2, a mounting plate 7 is slidably connected to one side of the vertical plate 6, a simulation test board 8 is clamped and installed on the top of the mounting plate 7, a simulation ear canal is opened on one side of the simulation test board 8, the earphone plug body 5 matches the simulation ear canal, and a transparent cover 9 is sealed and clamped on the top of the base 1.

[0031] Refer to the instruction manual Figure 2-3 A metal soft light board 10 is fixedly installed on one side of the top of the base 1 , and an ultraviolet lamp 11 is fixedly installed on one side of the metal soft light board 10 , and one side of the ultraviolet lamp 11 faces the direction of the earphone plug body 5 .

[0032] The present invention provides a metal soft lamp plate 10 for adjusting the irradiation direction of the ultraviolet lamp 11 so that the ultraviolet lamp 11 always irradiates the simulated ear canal position.

[0033] Refer to the instruction manual Figure 1-3 An exhaust pipe 12 is fixedly provided on the other side of the top of the base 1. One end of the exhaust pipe 12 passes through one side of the base 1 and extends to the outside, and the end thereof is fixedly connected to an external exhaust device.

[0034] After the transparent cover 9 is engaged, the present invention uses an external air extraction device to extract air from the air extraction pipe 12 to keep the inside of the transparent cover 9 in a negative pressure state.

[0035] Refer to the instruction manual Figure 2-3 The test cylinder structure 2 includes an outer cylinder 201, the middle part of the inner side and the top of the inner side of the outer cylinder 201 are fixedly connected with an elastic soft ring 202, the outer cylinder 201 is fixedly embedded with an inner cylinder 203 through the elastic soft ring 202, and the top of the inner cylinder 203 extends out of the outer cylinder 201, and the polarization structure 3 includes a motor 301, the top of the motor 301 is fixedly connected with an eccentric block 302, and one side of the eccentric block 302 is in contact with the inner side of the inner cylinder 203.

[0036] The present invention starts the motor 301, and drives the eccentric block 302 to rotate through the motor 301, so as to strike the inner wall of the inner cylinder 203. Since the inner cylinder 203 is connected to the outer cylinder 201 through the elastic soft ring 202, the inner cylinder 203 will vibrate when struck.

[0037] Refer to the instruction manual Figure 2-4 The adjustment structure 4 includes an outer rod 401, one end of which is fixedly connected to the outer side of the inner tube 203, a gear rod 402 is slidably inserted inside the outer rod 401, one end of the gear rod 402 passes through the other end of the outer rod 401, and a connecting rope 403 is fixedly connected to its end, one end of the connecting rope 403 is fixedly connected to a mounting rod 404, the mounting rod 404 matches the earphone plug body 5, the top end of the gear rod 402 is meshedly connected to a gear rod 405, and one end of the gear rod 405 passes through the outer rod 401 and extends to the outside.

[0038] When testing the present invention, the earphone plug body 5 is placed on the mounting rod 404 and inserted into the simulated ear canal. The gear rod 405 can be used to adjust the length of the gear rod 402 extending out of the outer rod 401, so that when the earphone plug body 5 is located in the simulated ear canal of the simulated test board 8, the connecting rope 403 always remains in a straightened state, which can transmit the vibration of the inner tube 203, simulating the situation where the earphone plug body 5 is pulled when in use.

[0039] Refer to the instruction manual Figure 2-3 An inner cavity structure is provided inside the earphone plug body 5, and the inner cavity structure is filled with highly comfortable fluororubber surface protection UV glue protection oil.

[0040] The present invention utilizes the property of high-comfort fluororubber surface protection UV glue protection oil in the inner cavity structure to solidify under ultraviolet radiation, so that the earphone plug body 5 can be solidified and deformed according to the shape of the ear cavity. However, it is also necessary to test the sealing process of the present invention to prevent oil leakage.

[0041] Refer to the instruction manual Figure 2-3 A fastening bolt 701 is threadedly inserted on one side of the mounting plate 7, and one end of the fastening bolt 701 is threadedly connected to the vertical plate 6 for fixing the position of the mounting plate 7 after the position of the mounting plate 7 is adjusted.

[0042] Refer to the instruction manual Figure 2-3 The material of the simulation test board 8 is a silicone material filled with reinforcing ribs, and the reinforcing ribs are set to simulate the shape of the auricle cartilage.

[0043] The simulation test board 8 of the present invention is provided with a simulated ear canal and reinforcing ribs simulating the shape of human auricle cartilage, so that the parameters obtained in the simulation scenario are as close to the actual situation as possible.

[0044] The working principle and working process of the present invention are as follows: when the present invention is used, after the earphone plug body 5 is installed on the adjustment structure 4, the earphone plug body 5 is placed in the simulated ear canal of the simulated test board 8, and then the ultraviolet lamp 11 is turned on to irradiate the earphone plug body 5, so that the earphone plug body 5 is cured and changed according to the shape of the simulated ear canal. After the curing is completed, the height of the simulated test board 8 can be adjusted by the mounting plate 7, so that the connecting rope 403 presents a desired angle. After the adjustment is completed, the polarization structure 3 is started, and the polarization structure 3 knocks the test cylinder structure 2 through the eccentric block 302 to vibrate the inner cylinder 203. The inner cylinder 203 drives the adjustment structure 4 to pull the connecting rope 403, simulating the pulling force on the earphone plug body 5 during normal use, and then testing the anti-pulling function of the earphone plug body 5. After the test is completed, the earphone plug body 5 is taken out for observation, and the conditions of the earphone plug body 5 irradiated with the ultraviolet lamp 11 for different times are observed, so as to obtain the best ultraviolet irradiation time for the earphone plug body 5;

[0045] In addition, since the earphone plug body 5 of the present invention has an inner cavity structure and is injected with high-comfort fluororubber surface protection UV glue protection oil, oil leakage may occur if the sealing process is not done well during processing. Therefore, before testing the anti-pull function, the earphone plug body 5 and the mounting rod 404 are first put into the simulated ear canal, and then the transparent cover 9 is sealed and engaged. The air in the transparent cover 9 is then extracted through the exhaust pipe 12 to put the inside of the transparent cover 9 in a low-pressure state. After a period of time, the transparent cover 9 is opened and the earphone plug body 5 is removed to observe whether there is oil leakage, so as to calculate the product yield.
