Description

Technical Field

[0001] This utility model relates to the field of dental instrument technology, and in particular to a converter head for a dental light curing machine. Background Technology

[0002] Dental light-curing technology uses blue light of a specific wavelength to irradiate photosensitive resin, causing it to undergo a rapid free radical polymerization reaction and solidify. Photoinitiators such as camphorquinone absorb light energy to initiate monomer cross-linking, forming a structure with high compressive strength. This technology, thanks to the high energy penetration of blue light, can complete resin curing in a short time and is widely used in scenarios such as layered filling of caries, precise bonding of orthodontic brackets, and three-dimensional sealing of root canals. Traditional dental light-curing machines use a tail structure to connect to a light guide rod for the conversion head, and then perform the curing operation on the tooth, which is convenient for medical staff to replace and for daily protection.

[0003] Traditional dental light-curing machine adapters are usually one-piece molded. When curing teeth, they usually need to be inserted deep into the oral cavity. However, due to the one-piece molding, it is not convenient to cure teeth deep inside the oral cavity. The angle cannot be adjusted arbitrarily. In addition, the installation of oral support is usually not secure enough, and it needs to be adjusted repeatedly, which affects the efficiency of operation. Therefore, an adapter for dental light-curing machines is used to solve these problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a conversion head for a dental light curing machine, which aims to improve the problems of inconvenient angle adjustment and loose installation of oral support devices that require repeated adjustments due to the one-piece molding of the conversion head in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A conversion head for a dental light-curing machine includes a main rod, a gear block fixedly connected to the right side of the main rod, a rotating shaft rotatably connected inside the gear block, a connecting rod fixedly connected to the outer periphery of the rotating shaft, a rotating groove on the left side of the connecting rod, a telescopic groove on the top of the connecting rod, a fixed block slidably connected inside the left side of the connecting rod, a telescopic rod fixedly connected front and rear to the right side of the fixed block, an installation groove on the left side of the connecting rod, a spring fixedly connected to the right side of the telescopic rod, and an adjusting sleeve fixedly connected to the top of the telescopic rod.

[0007] As a further description of the above technical solution:

[0008] The connecting rod has a threaded groove on its right side, a magnetic base is fixedly connected to the right side of the connecting rod, a threaded rod is threadedly connected to the right side of the connecting rod, a magnetic block is slidably connected to the outer periphery of the threaded rod, an oral support is fixedly connected to the outer periphery of the magnetic block, and an installation hole is provided on the left side of the magnetic block.

[0009] As a further description of the above technical solution:

[0010] A lighting rod is fixedly connected to the left side of the main rod, and a lighting head is installed at the bottom of the lighting rod;

[0011] As a further description of the above technical solution:

[0012] The threaded rod is threaded in the threaded groove and slidably connected in the mounting hole;

[0013] As a further description of the above technical solution:

[0014] The right side of the magnetic base abuts against the left side of the magnetic block;

[0015] As a further description of the above technical solution:

[0016] The gear block is rotatably connected in the rotating groove, and the outer periphery of the gear block is meshed with the left side of the fixed block;

[0017] As a further description of the above technical solution:

[0018] The fixed block is slidably connected within the telescopic groove, and the telescopic rod is slidably connected within the telescopic groove;

[0019] As a further description of the above technical solution:

[0020] The other end of the spring is fixedly connected to the right side of the mounting groove, and the inner side of the adjusting sleeve is slidably connected to the outer periphery of the connecting rod.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the rotating connection structure of the gear block and the rotating shaft, combined with the sliding design of the rotating groove and the fixed block on the connecting rod, enables the conversion head to achieve multi-directional angle adjustment, which solves the problem that the traditional one-piece molded structure cannot flexibly adjust the light angle. It can accurately align with the teeth deep in the oral cavity, and through the elastic locking mechanism of the telescopic rod and the spring, it ensures that there is no loosening or displacement after the angle is adjusted, which significantly improves the accuracy and convenience of the curing operation.

[0023] 2. In this utility model, the connection structure between the magnetic base and the threaded rod provides mechanical locking force by screwing the threaded rod into the threaded groove. At the same time, the magnetic attraction between the magnetic block and the magnetic base further enhances stability and installation efficiency, so that the oral support can withstand the external force generated by the patient's swallowing action after installation, without the need for repeated adjustments, effectively avoiding the risk of the support falling off, and greatly improving the efficiency of clinical operation.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-5This utility model provides an embodiment of a conversion head for a dental light-curing machine, including a main body rod 1, which is a supporting frame of the overall structure. A gear block 2 is fixedly connected to the right side of the main body rod 1. The gear block 2 is used to transmit adjustment torque and achieve angle locking. A rotating shaft 3 is rotatably connected inside the gear block 2, and a connecting rod 4 is fixedly connected to the outer periphery of the rotating shaft 3. A rotating groove 5 is opened on the left side of the connecting rod 4, and the gear block 2 is rotatably connected in the rotating groove 5. Through the linkage between the rotating shaft 3 and the connecting rod 4, the rotational motion of the gear block 2 is converted into multi-angle swing of the connecting rod 4 to adapt to the light angle requirements of different treatment sites in the oral cavity. A telescopic groove 8 is opened at the top of the connecting rod 4, and a fixed block 6 is slidably connected in the telescopic groove 8. A telescopic rod 7 is slidably connected in the telescopic groove 8. The telescopic groove 8 provides sliding guidance for the fixed block 6 and the telescopic rod 7, ensuring the stability of the structure and the coaxiality of the movement during the adjustment process. A fixed block 6 is slidably connected inside the left side of the connecting rod 4, and the outer periphery of the gear block 2 is meshed with the left side of the fixed block 6. By meshing with the gear block 2 through the toothed surface, when the fixed block 6 slides along the telescopic groove 8, the rotation state of the gear block 2 can be locked or released, realizing mechanical locking after angle adjustment. The right side of the fixed block 6 is fixedly connected to the front and rear of the telescopic rod 7. The left side of the connecting rod 4 has an internal installation groove 9. The right side of the telescopic rod 7 is fixedly connected to the spring 10. The other end of the spring 10 is fixedly connected to the right side of the installation groove 9. The telescopic rod 7 completes the telescopic action through the elasticity of the spring 10 to drive the fixed block 6 to move, thereby controlling the locking and unlocking state of the gear block 2. The top of the telescopic rod 7 is fixedly connected to the adjusting sleeve 11. The inner side of the adjusting sleeve 11 is slidably connected to the outer periphery of the connecting rod 4. Medical staff can drive the telescopic rod 7 to slide by pulling the adjusting sleeve 11 backward, realizing the switching of the locking state of the gear block 2. The left side of the main rod 1 is fixedly connected to the light rod 18. The bottom of the light rod 18 is equipped with a light head 19. The light rod 18 transmits the light source energy to the light head 19. The blue light of the light head 19 ensures the light intensity in the deep oral cavity and meets the energy requirements for resin curing.

[0034] Reference Figures 4-6In one embodiment of this utility model: a threaded groove 12 is provided on the right side of the connecting rod 4, and a magnetic base 14 is fixedly connected to the right side of the connecting rod 4. A threaded rod 13 is threadedly connected to the right side of the connecting rod 4, and the threaded rod 13 is threaded into the threaded groove 12. A magnetic block 15 is slidably connected to the outer periphery of the threaded rod 13. The threaded groove 12 and the threaded rod 13 cooperate to form a mechanical locking structure. The magnetic base 14 is made of neodymium iron boron permanent magnet material, providing an initial attraction force with the magnetic block 15 to assist in the rapid positioning of the oral cavity support 16. The right side of the magnetic base 14 abuts against the left side of the magnetic block 15. The oral support 16 is fixedly connected to the outer periphery of the 15. When the threaded rod 13 is screwed into the threaded groove 12, the magnetic block 15 is tightly pressed onto the magnetic base 14, forming a dual fixing structure of "mechanical thread locking + magnetic adsorption", which improves the support stability. The magnetic block 15 has an installation hole 17 on the left side, and the threaded rod 13 is slidably connected in the installation hole 17. The clearance fit between the threaded rod 13 and the installation hole 17 not only ensures the installation freedom of the magnetic block 15, but also eliminates the gap through the axial pressure after the thread is tightened, so that the oral support 16 can avoid repeated adjustments during the operation after installation, thus improving the operation efficiency.

[0035] Working principle:

[0036] When the light angle needs to be adjusted, medical staff pull the adjusting sleeve 11 backward, causing the telescopic rod 7 to slide in the telescopic groove 8 against the elastic force of the spring 10. This, in turn, pulls the fixing block 6 out of engagement with the gear block 2. At this time, the gear block 2 can rotate freely around the rotating shaft 3 in the rotating groove 5, causing the connecting rod 4 to achieve horizontal swing adjustment. After the angle is adjusted to the correct position, the adjusting sleeve 11 is released, the spring 10 pushes the telescopic rod 7 to reset, and the fixing block 6 re-engages with the gear block 2 through the toothed surface. The connecting rod 4 is then fixed in place by mechanical locking. The position is marked so that the light head 19 is accurately aligned with the deep treatment site in the oral cavity. When installing the oral support 16, the magnetic block 15 is first put on the threaded rod 13 through the mounting hole 17, so that the left side of the magnetic block 15 is magnetically attracted to the magnetic base 14 to achieve initial positioning. Then, the threaded rod 13 is rotated to screw it into the threaded groove 12. As the threaded rod 13 moves axially, the magnetic block 15 is tightly pressed onto the magnetic base 14, forming a double fixation to ensure that the oral support 16 stably supports the cheek tissue without the need for repeated adjustments during the operation.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
