Description

Technical Field

[0001] The utility model relates to the technical field of earphone hooks, in particular to a double-type hook that can be used for pure tone audiometry air conduction earphones. Background Art

[0002] At present, pure tone audiometry is a basic examination in ear, nose and throat examination. When patients feel discomfort in their ears, hearing tests are routinely performed.

[0003] Currently, hearing tests are performed with headphones, with the left and right headphones connected by a headband. A narrow headband will increase the pressure on the top of the head, affecting comfort and making it difficult to keep the left and right headphones balanced on the head. A headband that is too wide will increase the weight of the entire headset, affecting the patient's experience and not conducive to cost control. Currently, the width of the general headband is basically controlled at around 2.8-3.0cm.

[0004] During the pure tone audiometry test, depending on the patient's condition, some patients may also need to be equipped with air conduction headphones or bone conduction headphones (when the patient has air conduction problems, a bone conduction test is required). The overall structure of the bone conduction headphones is relatively small, so the headband is generally narrow.

[0005] In actual use, adhesive hooks are generally used to hang the headphones. These hooks can adapt to bone conduction headphones, but cannot adapt to headphones with a wider width. As a result, the headphones are prone to falling off when being hung, and the hooks may also crush the cotton blocks on the headphones. Summary of the invention

[0006] In view of the above problems, the utility model provides a double hook that can be used for pure tone audiometry air conduction earphones. Users can choose an appropriate hook according to actual usage requirements. It has the advantages of strong adaptability and high flexibility of use.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A double hook for pure tone audiometry air conduction earphones, comprising:

[0009] A mounting block, one side of which is a wall-adhesive surface;

[0010] A hanging plate, the bottom of which is hinged to the mounting block, and a first limiting member is provided at the bottom of the hanging plate, and when the hanging plate is flipped to a horizontal state, the first limiting member contacts the mounting block to limit the hanging plate from flipping downward; and

[0011] The bottom of the hanging rod is also hinged to the mounting block, and a second limiting member is provided at the bottom of the hanging rod. When the hanging rod is flipped to a horizontal state, the second limiting member contacts the mounting block to limit the hanging rod from flipping down.

[0012] In one embodiment, a first receiving groove is formed on the mounting block, and when the hanging plate is flipped to a vertical state, the hanging plate sinks into the first receiving groove.

[0013] In one embodiment, a second receiving groove is provided on the hanging plate, and when the hanging rod is flipped to a vertical state, the hanging rod sinks into the second receiving groove.

[0014] In one embodiment, a rotating shaft is provided at the bottom of the first receiving groove, and the bottoms of the hanging plate and the hanging rod are rotatably connected to the rotating shaft.

[0015] In one embodiment, the hanging plate comprises:

[0016] a fixed section, the bottom of which is fixedly connected to the first limiting member; and

[0017] The soft rubber segment is provided with two soft rubber segments, and the two soft rubber segments are respectively extended outwardly on both sides of the fixed segment.

[0018] In one embodiment, the hanging plate further includes an anti-slipping strip, which is disposed at a distal end of the fixing section. When the hanging plate is flipped to a horizontal state, the anti-slipping strip is disposed to protrude upward.

[0019] In one embodiment, the hanging plate and the hanging rod are both provided with ball columns on the side facing away from the mounting block.

[0023] The utility model adopts the above technical solution, which has the following advantages:

[0024] When using this double hook, the mounting block is pasted and fixed on the wall. When the earphone needs to be hung, a hanging plate or a hanging rod can be selected according to the width of the headband of the earphone for hanging. Among them, the hanging plate is wider as a whole, which can adapt to the hanging of earphones with wider headbands, while bone conduction earphones with narrower headbands can be hung by the hanging rod. When the hanging rod is selected, the hanging rod is rotated and pulled out until the second limiter contacts the mounting block. At this time, the hanging rod is rotated to a horizontal state, and then the earphone can be hung on the hanging rod. When the hanging plate is selected, the hanging plate is also rotated and pulled out until the first limiter contacts the mounting block.

[0035] In actual use, adhesive hooks are generally used to hang headphones. These hooks can adapt to bone conduction headphones, but cannot adapt to headphones with a wider width, resulting in the headphones being easily detached when hung, and the hooks also have the problem of crushing the cotton blocks on the headphones. In view of the above problems, the utility model provides a double hook that can be used for pure tone audiometry air conduction headphones. Users can choose an appropriate hook according to actual use needs. It has the advantages of strong adaptability and high flexibility of use. The specific solution is as follows.

[0036] Reference Figure 1 , Figure 2 as well as Figure 3 As shown, the utility model relates to a double-type hook that can be used for pure tone audiometry air conduction earphones, comprising a mounting block 10, a hanging plate 20 and a hanging rod 30, wherein one side of the mounting block 10 is attached to the wall. The bottom of the hanging plate 20 is hinged to the mounting block 10, and a first limiter 21 is provided at the bottom of the hanging plate 20. When the hanging plate 20 is flipped to a horizontal state, the first limiter 21 contacts the mounting block 10 to limit the hanging plate 20 from flipping down. The bottom of the hanging rod 30 is also hinged to the mounting block 10, and a second limiter 31 is provided at the bottom of the hanging rod 30. When the hanging rod 30 is flipped to a horizontal state, the second limiter 31 contacts the mounting block 10 to limit the hanging rod 30 from flipping down.

[0037] It should be noted that, in this embodiment, the wall-adhesive surface of the mounting block 10 is mainly used for pasting the adhesive layer, and the mounting block 10 is subsequently pasted and installed on the wall as a whole through the adhesive layer to achieve the function of installation and fixing. In addition, in order to facilitate the hanging of wider headband headphones, the overall width of the hanging plate 20 can be set to 3-5 cm, and in this embodiment, the overall width of the hanging plate 20 is set to 4 cm.

[0038] For example, when using the double hook, the mounting block 10 is pasted and fixed on the wall. When the earphone needs to be hung, the hanging plate 20 or the hanging rod 30 can be selected according to the width of the headband of the earphone for hanging. Among them, the hanging plate 20 is wider as a whole, which can adapt to the hanging of earphones with wider headbands, while the bone conduction earphones with narrower headbands can be hung by the hanging rod 30. When the hanging rod 30 is selected, the hanging rod 30 is rotated and pulled out until the second limiter 31 contacts the mounting block 10. At this time, the hanging rod 30 rotates to a horizontal state, and then the earphone can be hung on the hanging rod 30. When the hanging plate 20 is selected, the hanging plate 20 is also rotated and pulled out until the first limiter 21 contacts the mounting block 10. At this time, the hanging plate 20 rotates to a horizontal state. Through the coordinated setting of the hanging rod 30 and the hanging plate 20, the user can select an appropriate hook according to the actual use needs, which has the advantages of strong adaptability and high flexibility of use.

[0039] In one embodiment, the overall structure of the mounting block 10 is further refined, and a first receiving groove 11 is provided on the mounting block 10 . When the hanging plate 20 is flipped to a vertical state, the hanging plate 20 sinks into the first receiving groove 11 .

[0040] The coordinated arrangement of the first storage groove 11 and the hanging plate 20 can facilitate storage. When the double hook does not need to hang the earphones, the hanging plate 20 can be flipped upward and sunk into the first storage groove 11. Specifically, in this embodiment, when the hanging plate 20 is sunk into the first storage groove 11, the entire hanging plate 20 is flush with the surface of the mounting block 10, thereby optimizing the flatness of its appearance.

[0041] In this embodiment, further, a second receiving groove 22 is provided on the hanging plate 20 , and when the hanging rod 30 is flipped to a vertical state, the hanging rod 30 sinks into the second receiving groove 22 .

[0042] Specifically, the hanging rod 30 is integrally embedded in the hanging plate 20 structure. Since the overall structural size of the hanging rod 30 is relatively small, the arrangement of this structure can further optimize the overall structural rationality of the double-type hook and make it more compact.

[0043] In this embodiment, the rotation structure of the hanging plate 20 and the hanging rod 30 is further refined, wherein a rotating shaft 40 is provided at the bottom of the first storage groove 11, the bottom of the hanging plate 20 and the hanging rod 30 are both rotatably connected to the rotating shaft 40, and the hanging plate 20 and the hanging rod 30 are both rotatably connected to the mounting block 10 via the rotating shaft 40.

[0044] In one embodiment, preferably, the hanging plate 20 includes a fixed section 201 and a soft rubber section 202, wherein the bottom of the fixed section 201 is fixedly connected to the first stopper 21. Two soft rubber sections 202 are provided, and the two soft rubber sections 202 are respectively extended outwards on both sides of the fixed section 201.

[0045] It should be noted that the extended setting of the soft rubber section 202 can achieve soft support for the headband. When hanging the headphones, the gravity of the headphones will cause the headband to press down the hanging plate 20 as a whole. At this time, the fixed section 201 plays the main support, and the soft rubber section 202 will bend downward under the action of pressure in combination with the curvature of the headband. At this time, the soft rubber section 202 can not only play a role in auxiliary support and positioning, but also protect the headband, thereby further optimizing the hanging stability of the hanging plate 20.

[0046] In this embodiment, it is more preferred that the hanging plate 20 further includes an anti-slipping strip 203, which is arranged at the far end of the fixed section 201. When the hanging plate 20 is turned to a horizontal state, the anti-slipping strip 203 is arranged to protrude upward. The structure of the anti-slipping strip 203 has a limiting effect on the headband, limiting the headband from sliding off at the end of the fixed section 201.

[0047] In one embodiment, in order to facilitate the adjustment of the hanging plate 20 and the hanging rod 30, a ball column 50 is provided on the side of the hanging plate 20 and the hanging rod 30 facing away from the mounting block 10. When the hanging plate 20 or the hanging rod 30 needs to be rotated, the corresponding ball column 50 can be pulled.

[0048] In this embodiment, it is more preferable that the hanging plate 20 and the hanging rod 30 are both arranged with an interference fit with the rotating shaft 40, wherein the interference fit setting allows the rotation of the hanging plate 20 and the hanging rod 30 to produce a damping effect, and when the hanging plate 20 and the hanging rod 30 are in a vertical storage state, the damping can play a positioning role to prevent the hanging plate 20 and the hanging rod 30 from accidentally flipping down.

[0049] In one embodiment, it is more preferred that a winding rod 60 is provided on the mounting block 10, one end of the winding rod 60 is connected to the mounting block 10, and the other end of the winding rod 60 is horizontally extended in a direction away from the mounting block 10.

[0050] Specifically, the winding rod 60 is rotatably connected to the mounting block 10. The winding rod 60 is provided to provide a place for the earphone wires. When hanging the earphones, the earphone wires can be wound around the winding rod 60, so that the earphones can be stored more neatly. Among them, the rotatable connection structure allows the winding rod 60 to be adjusted in a specific position. When the double hook is in an idle storage state, the winding rod 60 can be rotated and recovered.

[0051] Specific implementation process:

[0052] When using the double hook, the mounting block 10 is pasted and fixed on the wall. When the earphone needs to be hung, the hanging plate 20 or the hanging rod 30 can be selected according to the width of the headband of the earphone for hanging. The hanging plate 20 is wider as a whole, and can be used to hang earphones with wider headbands, while the hanging rod 30 can be selected to hang bone conduction earphones with narrower headbands.

[0053] When the hanging rod 30 is selected, the hanging rod 30 is rotated and pulled out through the ball column 50 until the second stopper 31 contacts the mounting block 10. At this time, the hanging rod 30 is rotated to a horizontal state, and then the earphone can be hung on the hanging rod 30;

[0054] When the hanging plate 20 is selected, the hanging plate 20 is rotated and pulled out by the ball column 50 until the first stopper 21 contacts the mounting block 10, and the hanging plate 20 is rotated to a horizontal state;

[0055] After the earphones are hung, the wires of the earphones are wound around the winding rod 60 .

[0056] 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.
