DETAILED DESCRIPTION

[0044] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0045] Example 1

[0046] A hearing test device for ENT examination, such as Figure 1-Figure 10 As shown, it includes an installation frame 1, a first connecting member 2 is arranged on the top of the installation frame 1, the first connecting member 2 has a lifting ring, the first connecting member 2 is used for lifting connection, a driving motor 3 is arranged in the installation frame 1, a rotating frame 4 is connected to the output shaft of the driving motor 3, the rotating frame 4 is rotatably connected to the installation frame 1, a first driving motor 5 is installed on the right side of the rotating frame 4, a screw rod 6 is connected to the output shaft of the first driving motor 5, the screw rod 6 is rotatably connected to the rotating frame 4, a moving frame 7 is slidably connected in the rotating frame 4, the moving frame 7 is threadedly connected to the screw rod 6, and the lower side of the moving frame 7 is rotatable. A rotating plate 10 is connected in a fixed manner, a second driving motor 8 is installed on the upper front side of the moving frame 7, a first gear 9 is connected to the output shaft of the second driving motor 8, and a first gear 9 is also connected to the rotating plate 10. The two first gears 9 are meshed with each other. A first spring 11 is connected to the lower left side of the rotating plate 10, and a bell 12 is connected to the bottom end of the first spring 11. An adjusting mechanism 13 is provided on the mounting frame 1, and the adjusting mechanism 13 is used to adjust the working height position of the mounting frame 1. A sliding contact mechanism 14 is provided on the rotating frame 4, and the contact mechanism 14 is used to contact with the patient's head.

[0047] It should be noted that when conducting an ENT physical examination, the device can be used to perform a hearing test. First, the first connecting member 2 is used to complete the connection and lifting of the device. After the lifting is completed, the contact mechanism 14 is used to contact the patient's head to fix the overall shape of the device. Then the first drive motor 5 is started. The rotation of the output shaft of the first drive motor 5 will drive the screw rod 6 to rotate. The rotation of the screw rod 6 will drive the moving frame 7 to move. The movement of the moving frame 7 will drive the rotating plate 10 to adjust the position, so that the bell 12 can move to a suitable position. When the bell 12 moves to a suitable position, the first drive motor 5 is turned off, and then the drive motor 3 is started to drive the rotating frame to move, so that the bell 12 moves to a position closer to the test person's ear. Then the second drive motor 8 is started, so that the rotating plate 10 starts to rotate back and forth, thereby driving the first spring 11 to make the bell 12 start to shake, thereby achieving the effect of testing hearing.

[0048] The adjusting mechanism 13 includes a fixed column 131, and the upper sides of the left and right parts of the installation frame 1 are connected to the fixed columns 131. The fixed columns 131 are slidably and rotatably connected to the rotating sleeve columns 132. Two arc-shaped limit blocks are provided on the fixed column 131, and a plurality of blocking blocks are provided inside the rotating sleeve columns 132. The top of the rotating sleeve columns 132 is rotatably connected to the second connecting member 133, and the second connecting member 133 is also provided with a hanging ring. A pulley assembly 134 is connected between the rotating sleeve columns 132, and the pulley assembly 134 consists of a pulley and a transmission belt.

[0049] It should be noted that due to the different body shapes of different testers, the position of the device from the tester's head is also different. In order to improve the rigor and adaptability of the test, medical staff can rotate the rotating sleeve 132 on one side so that the blocking block no longer blocks the limit block. With each rotation, the fixed column 131 will move downward once, thereby achieving the effect of stage-by-stage adjustment of the height of the device, making the device more fit the patient's body shape and improving the accuracy of the test.

[0050] The contact mechanism 14 includes a sleeve 141. The sleeves 141 are arranged on both the front and rear sides of the right side of the rotating frame 4. A sliding frame 143 is slidably connected between the sleeves 141. The lower part of the sliding frame 143 is also slidably connected to two sleeves 141. A contact pad 142 is connected between the lower sides of the left parts of the lower sleeves 141.

[0051] It should be noted that before the operation, the sliding frame 143 is pulled to provide a spatial position for the rotating plate 10 to rotate. When in use, the contact pad 142 can be in contact with the patient's head. At this time, the contact pad 142 can assist the device to complete the most basic positioning processing. At the same time, the contact pad 142 can prevent the device from causing hard squeezing of the patient and reduce discomfort.

[0052] It also includes an anti-diffusion mechanism 15, which includes a fixed ring 151. The lower left side of the rotating plate 10 is connected to the fixed ring 151, and the lower side of the fixed ring 151 is rotatably connected to a rotating disk 152. The rotating disk 152 is provided with a blocking piece 153, which is used to concentrate the sound generated by the bell 12 to prevent the sound from diffusing.

[0053] It should be noted that during the hearing test, the position of the blocking plate 153 is adjusted according to the position of the bell 12 and the ear position of the test person. As the rotating plate 10 moves, the first spring 11 moves, causing the bell 12 to shake and produce sound. At this time, the blocking plate 153 can focus the sound to prevent the sound from diffusing and affecting the test effect.

[0054] Example 2

[0055] It also includes a blocking mechanism 16, which includes a connecting frame 161. The connecting frame 161 is arranged between the right parts of the upper sleeve 141. The front and rear parts of the connecting frame 161 are rotatably connected to the first rotating member 162. The bottom of the first rotating member 162 has a C-shaped block. The C-shaped block is used to block the lower sleeve 141. The front and rear parts of the connecting frame 161 are rotatably connected to the second gear 163. The second gear 163 is connected to the adjacent first rotating member 162. The connecting frame 161 is slidably connected to a rack rack 164. The rack rack 164 and the second gear 163 are meshed with each other. The upper part of the connecting frame 161 is connected to two front-to-back symmetrical fixing plates 165. The fixing plates 165 are used to block and limit the adjacent first rotating member 162.

[0056] It should be noted that in order to prevent the sliding frame 143 from accidentally driving the lower sleeve 141 to move when adjusting, the C-shaped block at the bottom of the first rotating member 162 is used to block the lower sleeve 141, thereby preventing the contact pad 142 from accidentally moving. After the position adjustment of the sliding frame 143 is completed, the first rotating member 162 is flipped upward. At this time, the corresponding second gear 163 will drive the rack frame 164 to move, thereby causing the corresponding second gear 163 on the other side to rotate, allowing the two first rotating members 162 to flip open synchronously.

[0057] It also includes a supporting mechanism 17, which includes a sliding member 171. The sliding member 171 is slidably connected to the rotating plate 10. A second spring 173 is connected between the sliding member 171 and the rotating plate 10. A pull rope 172 is connected between the right side of the sliding member 171 and the left side of the moving frame 7.

[0058] It should be noted that in order to improve the stability of the rotating plate 10 during movement, the pull rope 172 is used to pull the sliding member 171, so that under the action of the sliding member 171 and the second spring 173, the rotating plate 10 is pulled to prevent the left part of the rotating plate 10 from falling due to gravity and causing damage to the device.

[0059] It also includes a connecting mechanism 18, which includes a fixed tube 181. The front and rear sides of the left part of the rotating plate 10 are connected to the fixed tube 181. A second rotating member 182 is rotatably connected in the fixed tube 181. A volute spring 183 is connected between the second rotating member 182 and the adjacent fixed tube 181. A connecting component 184 is connected between the second rotating member 182 and the contact pad 142. The connecting component 184 and the contact pad 142 are a detachable connection structure.

[0060] It should be noted that when the device is not in use, the connection component 184 cooperates with the second rotating member 182 to pull the contact pad 142 to maintain the overall stability of the device. When it is needed to operate, the connection component 184 can be disengaged from the contact pad 142. In the initial state, the volute spring 183 is in a stressed state. When the connection component 184 is disengaged from the contact pad 142, the second rotating member 182 is rotated by the action of the volute spring 183, thereby retracting the connection component 184.

[0061] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
