[0023] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0024] Combine the following Figures 1 to 4 The utility model is described in detail.
[0025] A jaw support device for ophthalmic examination includes a main body 1, a bracket 101 is arranged on the top of the main body 1, a jaw support groove 1011 is arranged in the middle of the top of the bracket 101, a connecting frame 102 is arranged on the top of the main body 1, a head support 103 is arranged in the middle of the connecting frame 102, slide grooves 1012 are arranged on both sides of the opening of the jaw support groove 1011, a bonding layer 2 is arranged in the middle of the jaw support groove 1011, connecting layers 201 are arranged at both ends of the bonding layer 2, the connecting layer 201 cooperates with the slide groove 1012, a limiting component is arranged at one end of the connecting layer 201, the limiting component moves along the slide groove 1012, the slide groove 1012 also includes a guide wheel 1013, the guide wheel 1013 is arranged at one end of the middle of the slide groove 1012, the guide wheel 1013 is bonded to the connection between the two ends of the bonding layer 2 and the connecting layer 201, and the bonding layer 2 and the connecting layer 201 are made of rubber material.
[0026] First, the person who needs to undergo an eye examination puts his head into the bracket 101, and then places the lower jaw on the jaw bracket 1011 to support the head, while the forehead rests on the headrest 103, thereby providing certain support and stability for the head.
[0027] When the lower jaw is placed in the jaw bracket 1011, it will first contact the fitting layer 2. Then, due to the downward pressure of the weight of the human head, the fitting layer 2 will be forced to shrink and deform toward the jaw bracket 1011, thereby adapting to the lower jaws of people of different body shapes and avoiding the lower jaw being unable to adapt to the jaw bracket 1011, causing discomfort when supporting it and causing the human head to shake.
[0028] At the same time, when the bonding layer 2 is deformed due to the downward pressure of the weight, the connecting layers 201 on both sides will be pulled to adapt to the downward pressure deformation of the bonding layer 2. When the connecting layer 201 is pulled to move, it moves along the slide groove 1012. When the connecting layer 201 is pulled and moved, the slider 202 connected at one end will be driven to move together. At the same time, the slider 202 is limited and cooperated with the slide groove 1012 through the limiting blocks 2021 on both sides, so that the slider 202 will only translate along the slider 202 without separation, and the connecting layer 201 is also limited to move.
[0029] Furthermore, the limiting component includes a slider 202, a limiting block 2021, a displacement block 203 and a supporting layer 204. The slider 202 is arranged at one end of the connecting layer 201, the limiting blocks 2021 are arranged on both sides of the slider 202, the displacement blocks 203 are arranged on the top of the limiting blocks 2021, and the supporting layer 204 is arranged on one side of the displacement block 203. The limiting blocks 2021 are long strip-shaped protrusions on both sides of the slider 202, and the limiting blocks 2021 cooperate with the grooves on both sides of the middle of the slide groove 1012. The displacement block 203 is a plate arranged upright on the top of the slider 202, and the supporting layer 204 is an arc-shaped rubber layer arranged on the opposite side of the two displacement blocks 203. One side of the slider 202 is connected to one end of the middle of the slide groove 1012 through a spring.
[0030] When the slider 202 is pulled to move, the displacement block 203 will also be driven toward the center until the supporting layer 204 on one side fits against the two sides of the human head. The elastic setting of the supporting layer 204 enables it to fit softly against the two sides of the human head, and the weight generated by the falling head will also apply force to the clamping of the supporting layer 204, so that when the lower jaw is fitted and lifted, the supporting layer 204 can also be pressed and clamped to stabilize the human head and prevent the head from shaking and affecting the examination of the eyes. Finally, one side of the slider 202 is connected to one end of the slide groove 1012 through a spring, so that the slider 202 can be reset by the spring after being pulled and moved, and the fitting layer 2 can also be reset and pulled.
[0031] The following is a specific implementation process of the utility model. First, the person who needs to undergo an ophthalmic examination puts his head into the bracket 101, and then places the lower jaw on the jaw bracket 1011 to support the person's head, and at the same time the forehead rests on the head support 103, so as to provide a certain degree of support and stability for the person's head. When the lower jaw is placed on the jaw bracket 1011, it will first contact the bonding layer 2. Then, due to the downward pressure of the weight of the person's head, the bonding layer 2 will be forced to shrink and deform toward the jaw bracket 1011, so as to adapt to the lower jaw of people of different body shapes, so as to avoid the lower jaw being unable to adapt to the jaw bracket 1011, causing discomfort during support, causing the person's head to shake, and at the same time, when the bonding layer 2 is deformed due to the downward pressure of the weight, the connecting layers 201 on both sides will be pulled to adapt to the downward pressure deformation of the bonding layer 2, and when the connecting layer 201 is pulled to move, it moves along the slide groove 1012, and when the connecting layer 201 is pulled and moved, it will drive the slider 2 connected at one end 02 moves together, and at the same time, the slider 202 is limited and matched with the slide groove 1012 through the limiting blocks 2021 on both sides, so that the slider 202 can only translate along the slider 202 without separation, and at the same time, the connecting layer 201 is limited and moved. When the slider 202 is pulled to move, the displacement block 203 will also be driven to move closer to the center until the supporting layer 204 on one side is fitted to the two sides of the person's head. The elastic setting of the supporting layer 204 makes it possible to gently fit to the two sides of the person's head, and the weight generated by the falling head will also apply force to the clamping of the supporting layer 204, so that when the lower jaw is fitted and lifted, the supporting layer 204 can also be pressed and clamped to stabilize the person's head and prevent the head from shaking and affecting the examination of the eyes. Finally, one side of the slider 202 is connected to one end of the slide groove 1012 through a spring, so that the slider 202 can be reset by the spring after being pulled and moved, and the fitting layer 2 can be reset and pulled.
