Description

Technical Field

[0001] This utility model belongs to the field of dental drilling technology, specifically a dental drilling device. Background Technology

[0002] Dental drills, also known as dental burs, are instruments used in dental surgery to remove material attached to teeth. They come in various shapes and sizes to suit the needs of different surgeries. In dental surgery, dental drills are used to drill open teeth so that subsequent treatments can be performed. Round drills are suitable for most teeth, while horn drills and diamond twist drills are suitable for handling special cases, such as curved teeth or deep holes.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 4As shown, a dental drilling device according to an embodiment of the present invention includes a barrel 1, with an end cap 3 fixedly connected to one end of the barrel 1; a motor 2 fixedly connected inside the barrel 1; a transmission rod 6 provided at the output end of the motor 2; a first transmission block 7 fixedly connected to the end of the transmission rod 6 away from the motor 2; a third transmission block 10 rotatably connected inside the first transmission block 7; a second transmission block 8 rotatably connected to the side wall of the third transmission block 10, and the second transmission block 8 is correspondingly arranged to the first transmission block 7; a drill barrel 11 rotatably connected to the side wall of the second transmission block 8; a drill bit 14 fixedly connected to the end of the second transmission block 8 away from the first transmission block 7; the barrel 1... A first fixing block 9 is fixedly connected to the side wall; a second fixing block 12 is fixedly connected to the side wall of the drill barrel 11, and the second fixing block 12 is correspondingly arranged to the first fixing block 9; a hydraulic rod 13 is rotatably connected inside the first fixing block 9, and the end of the hydraulic rod 13 away from the first fixing block 9 is rotatably connected to the inside of the second fixing block 12; during operation, the operator can change the angle between the drill barrel 11 and the machine barrel 1 by driving the hydraulic rod 13, thereby adjusting the angle of the drill bit 14. During the process, whenever the hydraulic rod 13 is driven, that is, when the total length of the hydraulic rod 13 begins to increase, since the two ends of the hydraulic rod 13 are respectively connected to the first fixing block 9, the angle of the drill bit 14 is adjusted. A first fixed block 9 and a second fixed block 12 are rotatably connected, and the first fixed block 9 and the second fixed block 12 are respectively fixed to the side walls of the barrel 1 and the drill barrel 11. A first transmission block 7 and a second transmission block 8, rotatably connected inside the barrel 1 and the drill barrel 11, are connected by a third transmission block 10. As the hydraulic rod 13 extends, the drill barrel 11 will rotate relative to the barrel 1, and the second transmission block 8 inside the drill barrel 11 will rotate relative to the first transmission block 7. The operator can continuously drive the hydraulic rod 13 until the angle of the drill bit 14 reaches a predetermined value. Whenever drilling is required, the operator can drive the hydraulic rod 13 located in the barrel. The internal motor 2, due to the connection between the output end of the motor 2 and the transmission rod 6, can transmit the power of the motor 2 to the first transmission block 7 through the transmission rod 6, and finally realize the rotation of the drill bit 14. The end cap 3 fixed to the end of the barrel 1 serves to connect the wires and seal the end of the barrel 1. This step, by setting up a transmission assembly composed of the transmission rod 6, the first transmission block 7, the second transmission block 8, and the third transmission block 10, enables the drill bit 14 to rotate relative to the barrel 1, improving the flexibility and applicability of the dental drilling device, helping to solve the problem of drilling inconvenience in the process of gingival drilling, and improving the efficiency of gingival drilling.

[0025] like Figure 3As shown, a first fixing protrusion 15 is fixedly connected to the side wall of the barrel 1; a second fixing protrusion 16 is fixedly connected to the side wall of the drill barrel 11, and the first fixing protrusion 15 and the second fixing protrusion 16 are correspondingly arranged; a clamping screw 17 is fixedly connected to the side wall of the first fixing protrusion 15, and the second fixing protrusion 16 and the clamping screw 17 are rotatably connected; a clamping nut 18 is threadedly connected to the side wall of the clamping screw 17; during operation, whenever the angle of the drill bit 14 needs to be adjusted, the operator can first loosen the two clamping nuts 18, and then adjust the angle of the drill bit 14 through the hydraulic rod 13. After completion, the workers can tighten the two clamping nuts 18 respectively. When the clamping nuts 18 are tightened on the side wall of the second fixing protrusion 16, the second fixing protrusion 16 will be in close contact with the side wall of the first fixing protrusion 15 under the action of the clamping nuts 18. This step fixes the machine barrel 1 and the drill barrel 11 by setting up a fixing assembly composed of the first fixing protrusion 15, the second fixing protrusion 16, the clamping screw 17, and the clamping nuts 18, thereby limiting the angle of the drill bit 14, preventing the drill bit 14 from shaking violently during drilling, improving the stability of the device and enhancing its safety.

[0026] like Figure 2 As shown, a speed-changing block 4 is provided between the barrel 1 and the transmission rod 6, and the speed-changing block 4 is fixed to the inner wall of the barrel 1; a speed-changing slide 5 is provided on the top of the speed-changing block 4; a sliding groove is opened on the top of the barrel 1, and the size of the sliding groove is set according to the speed-changing slide 5; during operation, the operator can control the rotation speed of the drill bit 14 through the speed-changing slide 5. During the process, whenever the speed-changing slide 5 moves in the sliding groove at the top of the barrel 1, the contact relationship of each gear inside the speed-changing block 4 will change, and at this time, the rotation of the transmission rod 6 will change; this step adjusts the rotation speed of the transmission rod 6 by setting the speed-changing block 4 and the speed-changing slide 5, thereby controlling the rotation speed of the drill bit 14, improving the practicality and convenience of the device, and helping to solve the problem of the single drilling speed of the drilling device.

[0027] like Figure 1 and Figure 2 As shown, a control lever 19 is fixed to the side wall of the barrel 1, and the control lever 19 is set according to the size of the barrel 1; a sleeve 21 is provided on the side wall of the control lever 19, and the sleeve 21 is made of plastic; during operation, the operator can operate the device with the help of the control lever 19. The sleeve 21 on the side wall of the control lever 19 can increase the coefficient of friction by itself to avoid slippage; this step increases the contact area of ​​the device surface by setting the control lever 19 and the sleeve 21, which provides convenience for the operator to drill the gums, helps to avoid the device slipping, and reduces safety hazards.

[0028] like Figure 2As shown, a limiting piece 20 is fixedly attached to the side wall of the control lever 19, and the two limiting pieces 20 are positioned corresponding to the sleeve 21. During operation, the two limiting pieces 20 fixed to the side wall of the control lever 19 contact the top and bottom of the sleeve 21 respectively, and the two limiting pieces 20 can restrict the position of the sleeve 21 by contact. This step restricts the relative position of the sleeve 21 by setting the limiting pieces 20, thereby preventing the sleeve 21 from shifting or detaching during the drilling process of the device, enhancing the stability of the device and reducing safety hazards.

[0029] like Figure 3 As shown, a fixing plate 22 is fixedly connected to the side wall of the clamping nut 18, and the fixing plate 22 is threadedly connected to the clamping screw 17. During operation, the operator can rotate the clamping nut 18 with the help of the fixing plate 22, thereby more conveniently fixing the first fixing protrusion 15 and the second fixing protrusion 16. This step increases the torque on the clamping nut 18 by setting the fixing plate 22, which facilitates the operator's rotation of the clamping nut 18, improves the operator's drilling efficiency, and reduces patient discomfort.

[0030] like Figure 4 As shown, the first transmission block 7, the second transmission block 8, and the third transmission block 10 are made of titanium alloy. During operation, the titanium alloy materials of the first transmission block 7, the second transmission block 8, and the third transmission block 10 can leverage their high strength and corrosion resistance to maintain the structural stability of the components over a long period of time. This step enhances the structural strength of the device components by using titanium alloy materials for the first transmission block 7, the second transmission block 8, and the third transmission block 10, thereby maintaining the functional stability of the components, extending the service life of the device, and reducing maintenance requirements.

[0031] During operation, the operator can change the angle between the drill barrel 11 and the machine barrel 1 by driving the hydraulic rod 13, thereby adjusting the angle of the drill bit 14. During this process, whenever the hydraulic rod 13 is driven, i.e., when the total length of the hydraulic rod 13 begins to increase, since both ends of the hydraulic rod 13 are rotatably connected to the first fixed block 9 and the second fixed block 12 respectively, and the first fixed block 9 and the second fixed block 12 are respectively fixed to the side walls of the machine barrel 1 and the drill barrel 11, and the first transmission block 7 and the second transmission block 8, rotatably connected inside the machine barrel 1 and the drill barrel 11, are connected by the third transmission block 10, as the hydraulic rod 13 extends, the drill barrel 11 will move relative to the machine barrel... The rotation of the first transmission block 7 causes the second transmission block 8 inside the drill barrel 11 to rotate relative to the first transmission block 7. The operator can continuously drive the hydraulic rod 13 until the angle of the drill bit 14 reaches the predetermined value. Whenever drilling is required, the operator can drive the motor 2 located inside the barrel 1. Since the output end of the motor 2 is connected to the transmission rod 6, the power of the motor 2 can be transmitted to the first transmission block 7 through the transmission rod 6, ultimately realizing the rotation of the drill bit 14. The end cap 3 fixed to the end of the barrel 1 serves to connect the wires and seal the end of the barrel 1. Whenever the angle of the drill bit 14 needs to be adjusted, the operator can first loosen the two clamping nuts 1. 8. Then, adjust the angle of the drill bit 14 using the hydraulic rod 13. After the angle of the drill bit 14 is adjusted, the operator can tighten the two clamping nuts 18 respectively. When the clamping nuts 18 are tightened onto the side wall of the second fixing protrusion 16, the second fixing protrusion 16 will be in close contact with the side wall of the first fixing protrusion 15 under the action of the clamping nuts 18. The operator can control the rotation speed of the drill bit 14 through the speed change vane 5. During the process, whenever the speed change vane 5 moves in the groove at the top of the barrel 1, the contact relationship of the gears inside the speed change block 4 will change. At this time, the rotation of the transmission rod 6 will change. The operator can control the rotation speed using the control lever. 19 The device is operated, wherein the sleeve 21 set on the side wall of the control lever 19 can increase the friction coefficient by itself to avoid slippage. Two limiting pieces 20 fixed to the side wall of the control lever 19 contact the top and bottom of the sleeve 21 respectively. The two limiting pieces 20 can limit the position of the sleeve 21 by contact. The operator can use the fixing piece 22 to rotate and clamp the nut 18, thereby more conveniently completing the fixing of the first fixing protrusion 15 and the second fixing protrusion 16. The first transmission block 7, the second transmission block 8, and the third transmission block 10, which are made of titanium alloy, can give full play to their advantages of high strength and corrosion resistance, and maintain the structural stability of the components for a long time.
