[0035] At present, when conducting pure tone audiometry, in order to ensure the accuracy of the audiometry results, it is necessary to provide a good environment, that is, to isolate external noise interference. There are special soundproof rooms for examinations in hospitals. When going out for physical examinations, people generally choose to conduct screening in a relatively quiet room. If the screening results are abnormal and need to be re-examined, they will go to the hospital audiometry room for further examination. Since there are many people queuing for physical examinations, the opening and closing of doors and the movement of people will affect the examination results. In view of the above problems, the utility model provides a soundproof screen for outdoor pure tone audiometry examinations, which has the advantages of being easy to carry and install. The specific plan is as follows.

[0036] Reference Figure 1 , Figure 2 as well as Figure 3 As shown, the utility model relates to a soundproof screen for outdoor pure tone audiometry inspection, comprising a first soundproof board 1, a mounting base 2, a second soundproof board 3 and a third soundproof board 4. The mounting base 2 is fixedly arranged at the bottom of the first soundproof board 1, and a clamping groove 5 for mounting a triangular bracket is arranged at the bottom of the mounting base 2. One side of the second soundproof board 3 is hinged to one side of the first soundproof board 1, and the third soundproof board 4 is hinged to one side of the first soundproof board 1, and the third soundproof board 4 is located on the opposite side of the second soundproof board 3. Among them, when the second soundproof board 3 and the third soundproof board 4 are flipped and folded, the first soundproof board 1, the second soundproof board 3 and the third soundproof board 4 are laminated in sequence.

[0037] It should be noted that in this embodiment, in order to allow the second sound insulation board 3 and the third sound insulation board 4 to be stacked in a close fit when folded, the lengths of the hinge assembly of the second sound insulation board 3 and the hinge assembly of the third sound insulation board 4 are adaptively set to avoid structural interference between the second sound insulation board 3 and the third sound insulation board 4 during the flipping process. In addition, the clamping groove 5 located at the bottom of the mounting base 2 is matched with the clamping assembly of the tripod, and the clamping groove 5 can be adapted to the clamping assembly of, for example, a camera tripod.

[0038] For example, when the soundproof screen is used outdoors, the mounting base 2 can be fixedly mounted on a tripod as a whole through the snap-in slot 5, and then the third soundproof board 4 and the second soundproof board 3 can be gradually turned out, so that the second soundproof board 3 and the third soundproof board 4 are perpendicular to the first soundproof board 1. At this time, the soundproof screen presents a three-sided soundproof structure. During the inspection process, medical staff can guide the person to be inspected to enter the space formed by the soundproof screen for inspection. Even in an outdoor environment, the soundproof screen as a whole can rely on the first soundproof board 1, the second soundproof board 3 and the third soundproof board 4 to achieve excellent sound insulation effect. At the same time, the soundproof screen as a whole can also be flipped and folded for storage, so that the first soundproof board 1, the second soundproof board 3 and the third soundproof board 4 are stacked on each other, so that the soundproof screen can be carried outside, and has the advantage of convenient installation.

[0039] In one embodiment, the installation structure of the first sound insulation board 1 and the second sound insulation board 3 is further refined, wherein a first hinge assembly 6 is provided on the side of the first sound insulation board 1, and the second sound insulation board 3 is hinged to the first sound insulation board 1 through the first hinge assembly 6, and the first hinge assembly 6 includes a first fixing member 61, a first hinge member 62, and a first hinge shaft 63. The first fixing member 61 is fixedly connected to the first sound insulation board 1, the first hinge member 62 is fixedly connected to the second sound insulation board 3, and one end of the first hinge shaft 63 is connected to the first fixing member 61, and the other end is hinged to the first hinge member 62.

[0040] Furthermore, the installation structure of the first sound insulation board 1 and the third sound insulation board 4 is further refined. A second hinge assembly 7 is provided on the side of the first sound insulation board 1. The third sound insulation board 4 is hinged to the first sound insulation board 1 through the second hinge assembly 7. The second hinge assembly 7 includes a second fixing member 71, a second hinge member 72 and a second hinge shaft 73. Among them, the second fixing member 71 is fixedly connected to the first sound insulation board 1, the second hinge member 72 is fixedly connected to the third sound insulation board 4, and one end of the second hinge shaft 73 is connected to the first fixing member 61, and the other end is hinged to the second hinge member 72.

[0041] In this embodiment, specifically, the overall thickness of the first sound insulation board 1 , the second sound insulation board 3 and the third sound insulation board 4 are the same, and the difference between the length of the second hinge shaft 73 and the first hinge shaft 63 is the thickness value of the second sound insulation board 3 .

[0042] It should be noted that by controlling the length dimensions of the first hinge shaft 63 and the second hinge shaft 73, the folding and storage fit of the entire sound insulation screen can be optimized. At the same time, the problem of active interference between the second sound insulation board 3 and the second sound insulation board 3 can be avoided.

[0043] Specifically, in order to enhance the installation strength between components, in this embodiment, three first hinge assemblies 6 and three second hinge assemblies 7 are provided, and are spaced apart along the length direction of the side edge of the first sound insulation board 1 .

[0044] In this embodiment, it is more preferable that an auxiliary sound insulation strip 8 is provided on the first sound insulation board 1, and the auxiliary sound insulation strip 8 is correspondingly arranged on a side close to the third sound insulation board 4, and when the second sound insulation board 3 is folded, the second sound insulation board 3 and the auxiliary sound insulation strip 8 are arranged flush.

[0045] When the sound insulation screen is in the storage state, the second sound insulation board 3 is located between the first sound insulation board 1 and the third sound insulation board 4. When it is flipped to the use state, due to the length difference between the first hinge axis 63 and the second hinge axis 73, there will be a gap between the third sound insulation board 4 and the first sound insulation board 1. The setting of the auxiliary sound insulation strip 8 can make up for the gap, thereby optimizing the sound insulation effect between the first sound insulation board 1 and the third sound insulation board 4.

[0046] When conducting the test, earphones are generally used, and in order to facilitate hanging of the earphones, a hook 9 can be provided on the side of the third sound insulation board 4 or the second sound insulation board 3 , and in this embodiment, the hook 9 is fixedly mounted on the third sound insulation board 4 .

[0047] Specific implementation process:

[0048] When the soundproof screen is used outdoors, the mounting base 2 is fixedly mounted on the tripod as a whole through the snap-fitting groove 5, and then the third soundproof board 4 and the second soundproof board 3 are gradually turned out, so that the second soundproof board 3 and the third soundproof board 4 are perpendicular to the first soundproof board 1. During the inspection process, the medical staff can guide the person to be inspected to enter the space formed by the soundproof screen for inspection;

[0049] After the test is completed, the second sound insulation board 3 and the third sound insulation board 4 are flipped over to make the whole sound insulation screen in a folded and stacked state, and then the tripod is disassembled. At this time, the whole sound insulation screen is in a storage state, so that the sound insulation screen can be carried outside, and has the advantage of easy installation.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
