Description

Technical Field

[0001] The utility model generally relates to the technical field of medical devices, and in particular to a locking mechanism for a dental mirror. Background Art

[0002] Dental mirrors are common medical devices in dentistry. During an oral examination, doctors can use the reflection from the mirror on the top of the mirror to clearly and intuitively examine the various surfaces of the patient's teeth, thereby providing a more accurate diagnosis of the patient's oral condition. However, the lens and handle of traditional dental mirrors are fixed together, making it impossible to remove and replace the lens. This not only makes it difficult to clean and disinfect the lens, but also, for children with smaller mouths, the larger lens may cause oral discomfort, making examination difficult.

[0003] To address these issues, dental mirrors with detachable lenses and handles are now available on the market. For example, a patent for a dental mirror for oral examinations (application number: CN202121002286.9) describes a disassembly lever fixed to the bottom end of the mirror body. A reducing seat is located at the end of a connecting sleeve, and an annular reducing ring with external threads and corresponding internal threads is located at the top end of the reducing seat. To install the mirror body, the end of the disassembly lever is passed through the reducing cap, the reducing ring, and the reducing seat, and the reducing cap is rotated to shorten the reducing ring, thereby securely locking the disassembly lever to the reducing seat and, consequently, the mirror body to the connecting sleeve. Reversing this process allows disassembly.

[0004] Although the above solution realizes a detachable connection between the oral mirror body and the connecting sleeve, and the locking method is relatively reliable, there are the following problems: during the process of replacing and disassembling the oral mirror body, it is necessary to repeatedly rotate the reducing cap to lock or unlock the oral mirror body, which is cumbersome and not simple enough.

[0005] Therefore, how to make the dental mirror body detachably arranged on the connecting sleeve while making the locking operation between the two simple and portable has become a major problem that needs to be solved at present. Summary of the Invention

[0006] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a dental mirror locking mechanism. A first cantilever on the rear side of the dental mirror body is connected to the inner wall of the grip portion via a snap-fit structure, allowing the dental mirror body to be detachably connected to the grip portion and a relatively simple connection structure between the two. Furthermore, a locking member is provided between the first cantilever arms on both sides. Simply sliding the locking member back and forth can constrain or prevent deformation of the first cantilever arms, thereby adjusting the dental mirror body and the grip portion to lock or separate with each other, making the locking operation between the two very simple and convenient.

[0007] The effect of the utility model is achieved in this way:

[0008] The present application provides a dental mirror locking mechanism, comprising a dental mirror body and a gripping portion, the gripping portion being a hollow shell-like structure, wherein the hollow portion forms a first connecting cavity, the front end of the gripping portion being hollowed out with a plug hole, the plug hole being connected to the first connecting cavity; the rear end of the dental mirror body is protruded with two left-right symmetrical first cantilevers, the two first cantilevers penetrate into the first connecting cavity through the plug holes; the two first cantilevers are close to the left and right inner walls of the gripping portion, and the first cantilevers and the inner wall of the gripping portion are connected by a snap-fit structure, the snap-fit structure comprising a first hook and a first slot, the first hook being arranged at one of the top end of the first cantilever and the inner wall of the gripping portion, the first slot being recessed at the other of the top end of the first cantilever and the inner wall of the gripping portion; the first cantilever has elastic deformation capability, and the space between the two first cantilevers A first sliding area is formed at the interval, and a locking piece is connected to the first sliding area, and the left and right ends of the locking piece abut against the first cantilevers on the left and right sides and the locking piece can slide back and forth along the length direction of the first cantilever; the first cantilever has a switchable locking state and an active state. In the active state, the locking piece slides forward to a position close to the oral mirror body, and the front end of the first cantilever can be deformed under the influence of external force, and drives the first hook to disengage from the first bayonet, so that the oral mirror body and the gripping part can be separated from each other; in the locked state, the locking piece slides backward to a position close to the gripping part, and the left and right ends of the locking piece abut against the front ends of the two first cantilevers, so that the first cantilever cannot be deformed, and the first hook cannot be disengaged from the first bayonet, thereby making the oral mirror body and the gripping part relatively fixed.

[0009] Furthermore, the dental mirror body is a hollow shell-like structure, wherein the hollow portion forms a second connecting cavity. A first escape opening is defined at the rear end of the dental mirror body, through which the locking member passes and slides within the first and second connecting cavities. By also providing the dental mirror body with a hollow structure, the locking member can be designed to be larger, occupying a larger space, thereby making adjustment easier.

[0010] Furthermore, sliding support portions protrude from the left and right side walls of the dental mirror body near the first avoidance opening, and sliding grooves extending in the front-to-back direction are recessed on the left and right sides of the locking member. The sliding support portions snap into the sliding grooves, allowing the locking member to slide back and forth relative to the sliding support portions. As the locking member slides back and forth, its left and right sides are supported by the sliding support portions, thereby maintaining the locking member relatively fixed to the dental mirror body in the vertical direction, and making the sliding adjustment operation of the locking member smoother.

[0011] Furthermore, a second escape opening is hollowed out at the bottom of the dental mirror body, communicating with the first escape opening. The locking member includes an adjustment portion at the bottom that extends downwardly beyond the second escape opening and is configured to allow the user to adjust the locking member. The user can directly control the locking member through the adjustment portion exposed at the bottom of the dental mirror body, further simplifying the adjustment operation.

[0012] Furthermore, a limiting piece is provided in the second connecting cavity, and a middle recess of the limiting piece is provided with a second sliding area that passes through the front and back, and a limiting portion is provided in the second sliding area; the locking piece includes an abutting portion at the top for abutting the first cantilever on both sides, and a plurality of second cantilevers protrude from the rear side of the abutting portion, the second cantilever penetrates the second sliding area and fits the limiting portion; the second cantilever has elastic deformation ability, and a limiting mechanism is provided between the second cantilever and the limiting portion. The limiting mechanism includes a second hook arranged at the front end of the second cantilever and a second slot correspondingly recessed and arranged in the limiting portion; when the first cantilever is in the locked state, the second hook is engaged with the second slot, so that the second cantilever is positioned in the limiting portion, thereby driving the locking piece and the limiting piece to remain relatively fixed; when the second cantilever is switched to the active state, the second cantilever is deformed under the influence of external force, so that the second hook disengages from the second slot, and thereby the locking piece can slide back and forth relative to the limiting piece again. The locking part cannot slide easily in the locked state, and the connection stability between the dental mirror body and the grip is higher; and when it needs to be switched to the active state, the locking part can be unlocked by simply pushing it forward with force, which is easy to operate.

[0013] Furthermore, a second avoidance opening is hollowed out at the bottom end of the oral mirror body, the second avoidance opening being connected to the first avoidance opening, and two symmetrical positioning parts are provided near the second avoidance opening in the second connecting cavity; the limiting member includes a support portion provided horizontally at the bottom, the left and right sides of the support portion both extend upward to form a connecting portion, the interval between the connecting portions on both sides forms a second sliding area, and the front ends of the two connecting portions both extend in the left and right directions to form a stop portion; the front end of the support portion abuts against the front side wall of the second avoidance opening, and the rear end faces of the stop portions on both sides abut against the front end faces of the positioning parts on both sides, thereby keeping the limiting member relatively fixed to the oral mirror body in the front-to-back direction. This increases the connection strength between the limiting member and the oral mirror body; and, since the limiting member does not need to be detachably provided with the oral mirror body, the assembly of the oral mirror body is simpler.

[0014] Furthermore, the top of the positioning portion is connected to a cover plate, the top of the stopper abuts against the cover plate, and the bottom of the stopper abuts against the dental mirror body, so that the limiter and the dental mirror body remain relatively fixed in the vertical direction, further improving the connection strength between the limiter and the dental mirror body.

[0015] Furthermore, a horizontal gap exists between the connecting portions on both sides and the left and right side walls of the second avoidance opening, forming an avoidance zone. The locking member includes an adjustment portion disposed horizontally at the bottom, the adjustment portion abuts the bottom end of the support portion, and both left and right sides of the adjustment portion extend upward to form transition portions. The transition portions on both sides pass through the avoidance zone into the second connecting cavity and connect to the abutment portion. The adjustment portion extends downward beyond the second avoidance opening, and the adjustment portion is configured to allow the user to adjust the locking member. When the user slides the adjustment portion back and forth, the transition portion is driven to slide back and forth within the avoidance zone, thereby driving the abutment portion at its top to slide back and forth within the first sliding zone, further enhancing the ease of adjustment of the locking member.

[0016] Furthermore, the first hook is provided at the top of the first cantilever, and the first bayonet recess is provided on the left and right inner walls of the grip portion. The first cantilever is relatively narrow, and by providing the first hook at the first cantilever, the strength of the first cantilever is prevented from being affected by the groove.

[0017] Furthermore, the top ends of the left and right first cantilevers extend toward the first sliding area to form abutment limiters configured to prevent the locking member from separating from the first cantilever when sliding backward, thereby further improving the stability of the sliding adjustment operation of the locking member.

[0018] Furthermore, the rear side of the dental mirror body extends to form a docking portion with a U-shaped cross-section. The upper end and left and right ends of the grip are recessed to form docking grooves. When the dental mirror body is inserted into the grip, the first cantilever is guided by the docking portion and the docking groove to align with the insertion hole, making docking between the dental mirror body and the grip even easier.

[0019] Furthermore, a camera module is integrated into the oral mirror body, configured to capture images reflected by a reflective mirror on the oral mirror body. A first PCB board is also provided at the rear end of the oral mirror body, configured to store information captured by the camera module. A second PCB board is also provided within the first connecting cavity, and an electrical connection port is hollowed out at the front end of the grip portion, the electrical connection port facing the second PCB board. When the oral mirror body is connected to the grip portion, the first PCB board docks with the second PCB board via the electrical connection port, and the second PCB board is configured to receive and store information stored on the first PCB board. The provision of the camera module allows the user to observe the interior of the oral cavity more clearly and intuitively through the images captured by the camera module, thereby improving practicality. Furthermore, the first PCB board on the rear side of the oral mirror body can dock with the second PCB board on the grip portion via the electrical connection port, thereby transmitting and storing data. This ensures that even if the oral mirror body and the grip portion are disassembled, the storage of data captured by the camera module will not be affected, thereby making the use of the oral mirror more convenient.

[0020] Furthermore, the grip portion can be detachably connected to the tongue depressor. Two third cantilevers are symmetrically protruding from the rear end of the tongue depressor. The two third cantilevers penetrate into the first connecting cavity through the plug hole. The two third cantilevers are close to the left and right inner walls of the grip portion, and the third cantilever and the inner wall of the grip portion are connected by a snap-fit structure. The snap-fit structure includes a third hook and a third slot. The third hook is provided at the top of the third cantilever and one of the inner walls of the grip portion, and the third slot is recessed at the top of the third cantilever and the other of the inner walls of the grip portion. The third cantilever has elastic deformation ability, so that the third hook can be snapped into or out of the third slot by means of the elastic deformation of the third cantilever, thereby making the tongue depressor detachable to the grip portion. This allows the user to replace the tongue depressor or the oral mirror body according to the usage, expand the function, and improve practicality. In addition, the third cantilever on the rear side of the tongue depressor is detachably connected to the inner wall of the grip portion through the snap-fit structure, making the connection structure between the two simple and easy to install and remove.

[0021] Furthermore, a third hook is provided at the top of the third cantilever, and a third notch is correspondingly provided on the inner wall of the grip portion. Furthermore, the third notch is a through hole, so that the third hook is engaged with the third notch and is exposed on the side wall of the grip portion. This allows the user to deform the third cantilever by pulling on the third hook exposed on the grip portion, thereby disengaging the third hook from the third notch and removing the tongue depressor from the grip portion, further enhancing the convenience of installing and removing the tongue depressor.

[0022] The oral mirror locking mechanism provided in the present application is characterized in that the first cantilever on the rear side of the oral mirror body is connected to the inner wall of the gripping part through a snap-fit structure, so that the oral mirror body can be detachably connected to the gripping part and the connection structure between the two is relatively simple; and a locking piece is provided between the first cantilever on both sides, and the locking piece only needs to be slid back and forth to restrain or avoid deformation of the first cantilever, thereby adjusting the oral mirror body and the gripping part to lock or separate with each other, making the locking operation between the two very simple and convenient.

DETAILED DESCRIPTION

[0039] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0040] Please refer to the attached Figure 1-14The embodiment of the present application provides a dental mirror locking mechanism, comprising a dental mirror body 1 and a gripping portion 2. The gripping portion 2 is a hollow shell-like structure, wherein the hollow portion forms a first connecting cavity 201. A plug hole 202 is hollowed out at the front end of the gripping portion 2, and the plug hole 202 is connected to the first connecting cavity 201. Two first cantilevers 110 are protruding from the rear end of the dental mirror body 1, and the two first cantilevers 110 penetrate into the first connecting cavity 201 through the plug hole 202. The two first cantilevers 110 are inserted into the first connecting cavity 201 through the plug hole 202. The arm 110 is close to the inner walls of the left and right sides of the gripping portion 2, and the first cantilever 110 and the inner wall of the gripping portion 2 are connected by a snap-fit structure, which includes a first hook 111 and a first bayonet 203. The first hook 111 is set at one of the top of the first cantilever 110 and the inner wall of the gripping portion 2, and the first bayonet 203 is recessed and set at the other of the top of the first cantilever 110 and the inner wall of the gripping portion 2; the first cantilever 110 has elastic deformation ability, and the two first bayonet The interval between the cantilevers 110 forms a first sliding area 112, and a locking piece 3 is connected to the first sliding area 112. The left and right ends of the locking piece 3 abut against the first cantilevers 110 on the left and right sides, and the locking piece 3 can slide back and forth along the length direction of the first cantilever 110; the first cantilever 110 has a switchable locking state and an active state. In the active state, the locking piece 3 slides forward to a position close to the oral mirror body 1, and the front end of the first cantilever 110 can be deformed under the influence of external force, and drives the first hook 111 to disengage from the first bayonet 203, so that the oral mirror body 1 and the gripping part 2 can be separated from each other; in the locked state, the locking piece 3 slides backward to a position close to the gripping part 2, and the left and right ends of the locking piece 3 abut against the front ends of the two first cantilevers 110, so that the first cantilever 110 cannot be deformed, and the first hook 111 cannot be disengaged from the first bayonet 203, thereby making the oral mirror body 1 and the gripping part 2 relatively fixed.

[0041] In this embodiment, the first cantilever 110 on the rear side of the oral mirror body 1 is connected to the inner wall of the gripping part 2 through a snap-fit structure, so that the oral mirror body 1 can be detachably connected to the gripping part 2 and the connection structure between the two is relatively simple; and a locking member 3 is provided between the first cantilevers 110 on both sides, and the locking member 3 only needs to be slid back and forth to restrain or avoid deformation of the first cantilever 110, thereby adjusting the oral mirror body 1 and the gripping part 2 to lock or separate with each other, so that the locking operation between the two is very simple and convenient.

[0042] Please refer to the attached Figure 2-3 In some embodiments of the present application, the oral mirror body 1 is a hollow shell-like structure, wherein the hollow portion forms a second connecting cavity 101, and a first avoidance opening 102 is opened at the rear end of the oral mirror body 1. The locking member 3 passes through the first avoidance opening 102 and slides in the first connecting cavity 201 and the second connecting cavity 101.

[0043] In this embodiment, the first cantilever 110 is relatively short. If the locking member 3 as a whole can only slide in the first sliding area 112, the structure of the locking member 3 is relatively small and inconvenient for the user to operate. By setting the oral mirror body 1 as a hollow structure and the locking member 3 sliding in the first connecting cavity 201 and the second connecting cavity 101, the locking member 3 can be designed as a larger structure and occupy a larger space, thereby making the adjustment operation easier.

[0044] Please refer to the attached Figure 9 In some embodiments of the present application, sliding support portions 103 protrude from the left and right side walls of the dental mirror body 1 near the first avoidance opening 102, and sliding grooves 301 extending in the front-to-back direction are recessed on the left and right sides of the locking member 3. The sliding support portions 103 snap into the sliding grooves 301, allowing the locking member 3 to slide back and forth relative to the sliding support portions 103. During the forward and backward sliding process of the locking member 3, the left and right sides are supported by the sliding support portions 103, thereby keeping the locking member 3 relatively fixed to the dental mirror body 1 in the vertical direction, and the sliding adjustment operation of the locking member 3 is more stable.

[0045] Please refer to the attached Figure 7-8 In some embodiments of the present application, a second escape opening 104 is hollowed out at the bottom of the dental mirror body 1, which communicates with the first escape opening 102. The locking member 3 includes an adjustment portion 310 at the bottom, which extends downwardly beyond the second escape opening 104. The adjustment portion 310 is configured to allow the user to adjust the locking member 3. The user can directly control the locking member 3 through the adjustment portion 310 exposed at the bottom of the dental mirror body 1, further simplifying the adjustment operation of the locking member 3.

[0046] Please refer to the attached Figure 5-6In some embodiments of the present application, the second connecting cavity 101 is provided with a limiting member 4, and the middle part of the limiting member 4 is recessed to provide a second sliding area 401 that passes through the front and back, and a limiting portion 410 is provided in the second sliding area 401; the locking member 3 includes an abutting portion 320 at the top for abutting the first cantilevers 110 on both sides, and a plurality of second cantilevers 321 protrude from the rear side of the abutting portion 320, and the second cantilevers 321 penetrate into the second sliding area 401 and fit the limiting portion 410; the second cantilever 321 has elastic deformation ability, and a limiting mechanism is provided between the second cantilever 321 and the limiting portion 410, and the limiting mechanism The structure includes a second hook 322 arranged at the front end of the second cantilever 321 and a second slot 411 correspondingly recessed and arranged in the limiting portion 410; when the first cantilever 110 is in a locked state, the second hook 322 is engaged with the second slot 411, so that the second cantilever 321 is positioned at the limiting portion 410, thereby driving the locking member 3 and the limiting member 4 to remain relatively fixed; when the second cantilever 321 is switched to an active state, the second cantilever 321 is deformed under the influence of external force, so that the second hook 322 is disengaged from the second slot 411, thereby allowing the locking member 3 to slide back and forth relative to the limiting member 4 again.

[0047] In this embodiment, by setting a limiter 4, in the locked state, the second hook 322 is engaged with the second bayonet 411 so that the locking member 3 and the limiter 4 remain relatively fixed, so that the locking member 3 cannot slide easily in the locked state, and the connection stability between the oral mirror body 1 and the gripping part 2 is higher; and when it is necessary to switch to the active state, it is only necessary to forcefully push the locking member 3 forward so that the second cantilever 321 is deformed by the force and the second hook 322 is disengaged from the second bayonet 411, and the locking member 3 can slide freely again, so that the unlocking operation is also relatively simple.

[0048] Among them, preferably, two left-right symmetrical limiting parts 410 are provided in the second sliding area 401, and two left-right symmetrical second cantilevers 321 are correspondingly provided on the rear side of the abutting part 320, so that the connection strength between the locking part 3 and the limiting part 4 is higher and the stability is better.

[0049] Please refer to the attached Figure 5-6In some embodiments of the present application, a second avoidance opening 104 is hollowed out at the bottom end of the oral mirror body 1, and the second avoidance opening 104 is connected to the first avoidance opening 102. The second connecting cavity 101 is provided with two left-right symmetrical positioning parts 105 near the second avoidance opening 104; the limiting member 4 includes a supporting part 420 arranged horizontally at the bottom, and the left and right sides of the supporting part 420 extend upward to form a connecting part 430, and the interval between the connecting parts 430 on both sides forms a second sliding area 401, and the front ends of the two connecting parts 430 extend in the left and right directions to form a stop part 440; the front end of the supporting part 420 abuts against the front side wall of the second avoidance opening 104, and the rear end faces of the stop parts 440 on both sides abut against the front end faces of the positioning parts 105 on both sides, thereby making the limiting member 4 remain relatively fixed with the oral mirror body 1 in the front and back directions.

[0050] In this embodiment, when the locking member 3 slides back and forth, the limiting member 4 can still remain fixed in the front-to-back direction after the locking member 3 is pushed by the locking member 3, so that the connection strength between the limiting member 4 and the oral mirror body 1 is higher; and, the limiting member 4 does not need to be set as an integrated structure with the oral mirror body 1, and the two are detachably set, so that the assembly of the oral mirror body 1 is easier.

[0051] Please refer to the attached Figure 9-10 In some embodiments of the present application, the top of the positioning portion 105 is further connected to the cover plate 120, the top of the stopper 440 abuts against the cover plate 120, and the bottom of the stopper 440 abuts against the dental mirror body 1, so that the limiting member 4 remains relatively fixed to the dental mirror body 1 in the vertical direction, further improving the connection strength between the limiting member 4 and the dental mirror body 1.

[0052] Among them, the cover plate 120 is detachably arranged on the positioning part 105, and the side wall of the positioning part 105 is provided with studs. The left and right sides of the cover plate 120 are provided with connecting holes, so that the cover plate 120 can be connected to the above-mentioned studs through the connecting hole screws, making the installation and disassembly operations of the cover plate 120 easier; and after the cover plate 120 is disassembled, the limiter 4 can be moved at will in the vertical direction, so that the limiter 4 can be removed from the oral mirror body 1.

[0053] The cover plate 120 is an L-shaped plate, the horizontal portion of the cover plate 120 abuts against the positioning portion 105 , and the vertical portion of the cover plate 120 covers the first avoidance opening 102 , making the rear end of the oral mirror body 1 more integrated in appearance.

[0054] Please refer to the attached Figure 5-6In some embodiments of the present application, there is a gap in the horizontal direction between the connecting portions 430 on both sides and the left and right side walls of the second avoidance opening 104, and the gap forms an avoidance area 106; the locking member 3 includes an adjusting portion 310 arranged horizontally at the bottom, the adjusting portion 310 is attached to the bottom end of the supporting portion 420, and the left and right sides of the adjusting portion 310 extend upward to form a transition portion 330, the transition portions 330 on both sides pass through the avoidance area 106 into the second connecting cavity 101 and are connected to the abutting portion 320, the adjusting portion 310 extends downward beyond the second avoidance opening 104, and the adjusting portion 310 is configured for the user to adjust the locking member 3.
