[0002] The dental mirror is one of the commonly used instruments in dentistry. Dentists generally need to use a dental mirror when diagnosing and treating oral diseases for patients. It is usually composed of a magnifying lens, a guide rod, etc. When conducting an oral examination, the reflection principle of the lens can effectively increase the inspection field of view, and the disease condition in the patient's mouth can be seen through the dental mirror. The emergence of the dental mirror has brought a new model for oral examination and treatment. When the patient's lesions are displayed in front of the patient, the patient can understand the urgency of treatment without more description or professional knowledge.

[0003] Currently, most dental mirrors on the market cannot be adjusted in length. Due to the non-adjustable length, doctors may encounter problems with limited field of view and depth of field when using dental mirrors. Moreover, they are usually integrated structures. If a certain part is damaged, the damaged part cannot be replaced separately, which increases the cost of replacement. Therefore, a multifunctional dental mirror is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 A multifunctional oral mirror in this embodiment includes a lens 1 and a handheld part 2. A connecting block 3 is fixedly installed on the top of the lens 1, and a disassembly mechanism 4 is provided on the left and right sides of the connecting block 3.

[0024] The handheld part 2 includes a grip rod 201 , an adjusting rod 202 is installed through the top of the grip rod 201 , a lifting cylinder 203 is threadedly connected to the outer surface of the adjusting rod 202 , and a fixing block 204 is fixedly installed at the bottom of the lifting cylinder 203 .

[0025] A limit block located on the outer surface of the adjusting rod 202 is fixedly installed on the inner top wall of the grip rod 201, and the adjusting rod 202 is rotatably installed with the limit block. An anti-slip knob is fixedly installed on the top of the grip rod 201. The lifting cylinder 203 is slidably connected to the inner wall of the grip rod 201, and the lifting cylinder 203 passes through the bottom of the grip rod 201 and extends to the top of the fixed block 204.

[0026] The gripping rod 201 is the main part of the handheld part 2 and is used for holding. The adjusting rod 202 can rotate under the constraint of the limit block. The anti-slip knob is used to help rotate the adjusting rod 202 to provide better grip and operation. The outer surface of the adjusting rod 202 is connected to the lifting cylinder 203 by a thread, and the lifting cylinder 203 is slidably connected to the inner wall of the gripping rod 201, so the lifting cylinder 203 can be moved up and down by rotating the adjusting rod 202. The fixing block 204 is fixedly installed at the bottom of the lifting cylinder 203 and moves with the movement of the lifting cylinder 203, thereby changing the position of the lens 1 by changing the length of the handheld part 2. While obtaining a clear and magnified field of view, while maintaining a sufficient field of view and depth of field, the overall structure is compact, making the oral mirror easier to store and carry.

[0027] The disassembly mechanism 4 includes mounting blocks 401 fixedly mounted on the left and right sides of the connecting block 3, a slide plate 402 being movably mounted inside the two mounting blocks 401, a spring 403 being fixedly mounted between the inner walls of the two mounting blocks 401 and the side walls of the slide plate 402, an insert rod 404 being fixedly mounted on the other side of the two slide plates 402, a rotating cylinder 405 being rotatably mounted inside the two connecting blocks 3, and a driven rod 406 being fixedly mounted on the outer surfaces of the two rotating cylinders 405.

[0028] A mounting groove is provided on the top of the connecting block 3 , and the mounting groove is matched with the fixing block 204 .

[0029] The connecting block 3 is designed to cooperate with the fixing block 204 in the hand-held part 2. Specifically, the mounting groove designed on the top of the connecting block 3 is to accommodate and fix the fixing block 204 in the hand-held part 2, so as to connect the lens 1 and the hand-held part 2 together.

[0030] The left and right sides of the fixing block 204 are both provided with insertion holes adapted to the insertion rod 404 .

[0031] The size and shape of the insertion hole match the insertion rod 404 to ensure that the insertion rod 404 can be smoothly inserted and maintain appropriate connection strength, thereby achieving locking and disassembly between the fixing block 204 and the connecting block 3.

[0032] Slide blocks are fixedly mounted on both sides of the two slide plates 402 , and slide grooves matching the two slide blocks are formed on the inner walls of the two mounting blocks 401 , and the four slide blocks are slidably connected to the slide grooves.

[0033] With the sliding cooperation of the slider and the slide groove, the slide plate 402 can be stably moved horizontally left and right inside the mounting block 401, thereby ensuring that the insertion rod 404 can smoothly enter or exit the insertion hole of the fixed block 204. The spring 403 is fixedly installed between the inner wall of the mounting block 401 and the side wall of the slide plate 402. The spring 403 provides elastic force, which can push the slide plate 402 and the insertion rod 404 to reset.

[0034] The two insertion rods 404 are both fixedly mounted with convex rods, and the two follower rods 406 are both provided with sliding openings located on the outer surfaces of the convex rods, and the two sliding openings are both adapted to the convex rods.

[0035] Under the cooperation of the sliding opening and the protruding rod, when the driven rod 406 rotates, the insertion rod 404 can be moved left and right through the cooperation of the protruding rod and the sliding opening, so that it can enter or exit the insertion hole.

[0036] One end of the two rotating drums 405 penetrates through the side wall of the mounting block 401 and extends to the outside of the mounting block 401 , and a pressure rod is fixedly installed on the outer surface of the two rotating drums 405 .

[0037] The pressure rod is used to operate the rotation of the rotating drum 405, so as to realize the installation and disassembly between the fixed block 204 and the connecting block 3. The lens 1 and the hand-held part 2 are set as two detachable independent parts. When damaged, only the corresponding part needs to be replaced. In addition, the hand-held part 2 is set to be adjustable in length, which solves the problem that most of the lengths of the dental mirrors on the market cannot be adjusted. Due to the non-adjustable length, doctors may encounter problems with limited field of view and depth of field when using the dental mirror. Moreover, it is usually an integrated structure. If a part is damaged, the damaged part cannot be replaced separately, which increases the cost of replacement. Therefore, a multifunctional dental mirror is proposed to solve the above problem.

[0038] When implementing, follow these steps:

[0039] 1) When adjusting the length of the handheld part 2, firstly, the adjusting rod 202 is rotated by the anti-slip knob. The rotation of the adjusting rod 202 drives the lifting cylinder 203 to move up and down. The lifting cylinder 203 drives the fixing block 204 to move up and down, thereby driving the lens 1 to move up and down;

[0040] 2) When the lens 1 needs to be replaced, the pressure rod is first pressed, and the pressure rod drives the rotating cylinder 405 to rotate, and the rotating cylinder 405 drives the driven rod 406 to rotate. Under the cooperation of the convex rod and the sliding mouth, the driven rod 406 drives the surface of the convex rod to squeeze the inner wall of the sliding mouth when rotating, thereby driving the insertion rod 404 and the sliding plate 402 to move in the direction close to the spring 403, squeezing the spring 403;

[0041] 3) As the spring 403 contracts, the insertion rod 404 moves out of the insertion hole, releasing the lock on the fixing block 204;

[0042] 4) Finally, the fixing block 204 is withdrawn from the interior of the installation groove, and the lens 1 can be removed.

[0043] In summary, the multifunctional oral mirror, by setting the hand-held part 2 to an adjustable length structure, the doctor can adjust the position of the lens 1 according to the needs of himself and the patient, while obtaining a clear and magnified field of view, maintaining a sufficient field of view and depth of field, so as to better observe and deal with problems inside the oral cavity. Moreover, this design is more compact and easy to store, making the oral mirror easier to store and carry, which solves the problem that most of the oral mirrors on the market cannot be adjusted in length. Due to the non-adjustable length, the doctor may encounter the problem of limited field of view and depth of field when using the oral mirror.

[0044] Furthermore, by providing a disassembly mechanism 4, the fixing block 204 and the connecting block 3 can be easily separated, so that the lens 1 and the hand-held part 2 can be independently disassembled. In the case that the oral mirror is damaged, it is not necessary to replace the entire part, but only the damaged specific parts need to be replaced, thereby saving replacement costs and solving the problem that the oral mirrors on the market are usually an integrated structure. If a part is damaged, the damaged part cannot be replaced separately, which increases the replacement cost.
