Detailed Embodiments
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0021] Embodiment 1
[0022] Please refer to Figures 1 - 5 , an oral examination mirror shown in the figure, including a frame 101 and a handle 102 provided on one side of the frame 101. A lens 103 is provided in the frame 101, and further includes an installation component provided on the frame 101 for installing the lens 103;
[0023] The installation component includes an installation groove 201 opened on the inner wall of the frame 101. The installation groove 201 is matched with the lens 103. A through hole 202 is opened on the side of the installation groove 201 away from the handle 102. An installation plate 203 is provided in the through hole 202. A rubber protection pad is provided on the side of the installation plate 203 close to the lens 103. One end of the installation plate 203 is connected to the through hole 202 through a rotating shaft 204, and the other end of the installation plate 203 is connected to the through hole 202 through a limiting component;
[0024] It should be noted here that: through the setting of the installation component, under the action of the limiting component and the driving component, it is convenient to install and fix or release the fixation of the lens 103, further facilitating the separate replacement of the lens 103. Thus, while ensuring the use stability of the lens 103, the replacement convenience of the lens 103 is improved, and further the maintenance and use cost of the oral mirror is reduced.
[0025] Please refer to Figure 4 and Figure 5 , the limiting component shown in the figure includes a fixing hole 301 opened on the installation plate 203. Two symmetrically arranged limiting plates 302 are slidably connected in the fixing hole 301. Two limiting holes 303 are opened on the two opposite side walls of the through hole 202. The two limiting holes 303 are matched with the limiting plates 302. The installation plate 203 is provided with a driving component for driving the two limiting plates 302;
[0026] It should be noted here that: through the setting of the limiting component, it is convenient to limit the installation plate 203.
[0027] Please refer to Figure 4 and Figure 5 , inclined surfaces 304 are opened on the sides of the two limiting plates 302 close to the frame 101;
[0028] It should be noted here that: through the setting of the inclined surface 304, when the limiting plate 302 abuts against the side wall of the through hole 202, under the mutual acting force of the inclined surface 304 and the guiding action of the telescopic assembly, the limiting plate 302 will be pushed to contract into the fixing hole 301.
[0029] Working principle: When the oral endoscope is in use, first install the lens 103. During the installation process of the lens 103, the limiting effect between the mounting plate 203 and the through hole 202 is released by using the driving assembly. Then, the lens 103 is inserted into the mounting groove 201 from the through hole 202;
[0030] After the lens 103 is inserted into the mounting groove 201, rotate the mounting plate 203 so that the mounting plate 203 coincides with the through hole 202. And during the process of the mounting plate 203 coinciding with the through hole 202, when the limiting plate 302 abuts against the side wall of the through hole 202, under the mutual acting force of the inclined surface 304 and the guiding action of the telescopic assembly, the limiting plate 302 will be pushed to contract into the fixing hole 301. With the continuous pushing of the mounting plate 203, when the mounting plate 203 coincides with the through hole 202, the limiting plate 302 will coincide with the limiting hole 303. Thus, under the elastic action of the telescopic assembly, the limiting plate 302 will be pushed into the limiting hole 303 and abut against the bottom wall of the limiting hole 303. Thus, through the abutting action of the limiting plate 302, the installation and fixation of the mounting plate 203 are realized. Further, under the limiting action of the mounting groove 201 and the abutting action of the rubber pad on the side wall of the mounting plate 203, the installation and fixation of the lens 103 are realized;
[0031] When the lens 103 is damaged due to being knocked during use or after long-term use, and the clarity of the field of view decreases due to problems such as the lens 103 turning yellow or having scratches, the lens 103 needs to be replaced. During the replacement process of the lens 103, the connection limit between the mounting plate 203 and the through hole 202 is released by using the driving assembly, and then the mounting plate 203 can be rotated, so that the lens 103 is moved out from the through hole 202. Then, a new lens 103 is inserted from the through hole 202 and limited by the limiting assembly, and the replacement of the lens 103 is completed. The operation is simple and the implementation is convenient. While ensuring the use stability of the lens 103, the replacement convenience of the lens 103 is improved, so that it is convenient to replace the lens 103 alone, and the maintenance and use cost of the oral endoscope is reduced.
[0032] Embodiment 2
[0033] Please refer to Figure 4, This embodiment further illustrates Example 1. The drive assembly shown in the figure includes a drive rod 401 rotatably connected to the mounting plate 203. A gear 402 is fixedly connected to the side wall of the drive rod 401 located inside the fixing hole 301. Two racks 403 are slidably connected to the fixing hole 301. The two racks 403 are meshed with the gear 402. One end of the two racks 403 facing away from each other is fixedly connected to a drive plate 404. One end of the two drive plates 404 away from the racks 403 is connected to the limiting plate 302. The fixing hole 301 is provided with a telescopic assembly for telescoping the two racks 403. One end of the drive rod 401 away from the gear 402 is matched with the outer side wall of the lens frame 101, and a drive hole 405 provided in a regular hexagon shape is formed;
[0034] It should be noted here that: through the setting of the drive assembly, when it is necessary to release the connection limit between the mounting plate 203 and the through hole 202, use an Allen wrench to rotate the drive rod 401. During the rotation of the drive rod 401, the gear 402 is driven to rotate. Thus, under the meshing transmission action of the gear 402 and the two racks 403 and the guiding action of the telescopic assembly, the two limiting plates 302 will be driven to move closer to each other, so that the two limiting plates 302 are moved out of the limiting holes 303, thereby releasing the connection limit between the mounting plate 203 and the through hole 202.
[0035] Please refer to Figure 4 and Figure 5 , The telescopic assembly shown in the figure includes a fixing plate 501 fixedly connected to the inner wall of the fixing hole 301. Two T-shaped rods 502 are provided on one side of the fixing plate 501 close to the rack 403. A telescopic plate is slidably connected to the side walls of the two T-shaped rods 502. One side of the two telescopic plates facing each other is connected to the rack 403. Springs 503 are sleeved on the side walls of the two T-shaped rods 502. Two ends of the two springs 503 are respectively connected to the fixing plate 501 and the telescopic plate;
[0036] It should be noted here that: through the setting of the telescopic assembly, it provides a guiding and resetting function for the movement of the rack 403.
