Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a teeth grinding device. Background Art

[0002] Teeth are the hardest organs in the human body, but if you do not pay attention to oral hygiene, biofilm will gradually deposit on the surface of the teeth. Biofilm is composed of food residues, saliva, bacteria, etc., which can harden into tartar over time. When the tartar accumulates to a certain thickness, the bacteria inside it close to the surface of the teeth will corrode the mineral components in the enamel, further promoting the formation of caries, thereby causing various dental diseases.

[0003] Some patients need to clean tartar, others need fillings, and the current technology generally uses a tooth grinder to clean the patient's teeth before proceeding with subsequent dental procedures. However, teeth are not always arranged in the same position on the gums, and the existing tooth grinder has a fixed structure, making it difficult to adjust the angle. In addition, the tooth grinder lacks a roll-proof structure, and its cylindrical shape makes it easy for it to roll off the table and onto the ground, causing damage. Utility Model Content

[0004] The utility model aims to provide a teeth grinding device, which can conveniently adjust the angle and prevent the teeth grinding device from rolling.

[0005] To achieve the above objectives, the technical solution of the present utility model is as follows.

[0006] A grinding device comprises a shell, a rubber sleeve is provided on the lower side wall of the shell, a second rotating shaft is rotatably installed in the rubber sleeve, and a grinding column is provided at the outer end of the second rotating shaft; a motor is fixedly installed on the upper inner side wall of the shell, a first rotating shaft is provided inside the shell, one end of the first rotating shaft is connected to the output shaft of the motor, the other end of the first rotating shaft is fixedly connected to a cross-axis universal joint, and the other end of the cross-axis universal joint is connected to the second rotating shaft; a first L-shaped mounting plate is fixedly installed on the side wall of the shell, the first rotating shaft passes through the first L-shaped mounting plate, a second L-shaped mounting plate is provided inside the shell, and the cross-axis universal joint passes through the second L-shaped mounting plate, and an adjustment component is provided inside the shell, which is used to adjust the angle of the cross-axis universal joint, thereby realizing angle adjustment of the grinding column; two fixing seats are symmetrically provided on the outer side wall of the shell, a support block is hinged on the fixing seat, and an outer port of the support block is provided with a plug hole, and a fixing component is provided above the fixing seat on the outer side wall of the shell, and the adjustment fixing component is used to fix the support block when it is not in use.

[0007] It can be seen that when a patient needs to clean his teeth, he holds the shell with his hands, aligns the molar column with the teeth that need to be polished, starts the motor, and the output shaft of the motor drives the first shaft to rotate. The rotation of the first shaft drives the cross-axis universal joint to rotate. The rotation of the cross-axis universal joint drives the second shaft to rotate. The rotation of the second shaft drives the molar column to rotate, thereby polishing the teeth that need to be polished. When it is necessary to polish teeth at different positions, adjust the adjustment component to rotate the cross-axis universal joint, so that the rotation of the cross-axis universal joint drives the second shaft to rotate. At this time, the second L-shaped mounting plate rotates with the second shaft, thereby facilitating the polishing of teeth at different positions. After polishing is completed and the shell is placed on the desktop, adjust the fixing component to cancel the plug-in fixation of the support block, and rotate the two support blocks by hand. The two support blocks support the shell to prevent the shell from rolling on the table and falling to the ground and causing damage.

[0008] Furthermore, the adjustment assembly includes a third rotating shaft and a fourth rotating shaft; the third rotating shaft is rotatably mounted on the first L-shaped mounting plate, and the installation position of the third rotating shaft is relatively perpendicular to the cross-axis universal joint. The third rotating shaft extends to the outside of the shell, and a knob is provided at the outer end of the third rotating shaft. A first half gear is rotatably sleeved on the third rotating shaft between the first L-shaped mounting plate and the cross-axis universal joint; the fourth rotating shaft is rotatably mounted on the second L-shaped mounting plate, and the installation position of the fourth rotating shaft is relatively perpendicular to the cross-axis universal joint. A second half gear is rotatably sleeved on the fourth rotating shaft, and the second half gear is engaged with the first half gear.

[0009] When the angle of the molar column needs to be adjusted, the knob is turned by hand. The rotation of the knob drives the third shaft to start rotating, the rotation of the third shaft drives the first half gear to rotate, the engagement of the first half gear drives the second half gear to rotate, the rotation of the second half gear causes the fourth shaft and the second L-shaped mounting plate to start rotating, the rotation of the second L-shaped mounting plate drives the cross-axis universal joint to rotate, the rotation of the cross-axis universal joint drives the second shaft to rotate, and the rotation of the second shaft drives the molar column to rotate. At this time, the angle of the molar column can be easily adjusted.

[0010] Furthermore, the fixing assembly includes a sleeve and a spring; the sleeve is fixedly installed on the outer side wall of the shell, an insertion rod is inserted in the sleeve, a pinching handle is fixedly installed on the outer end of the insertion rod, the spring is sleeved on the insertion rod, one end of the spring is connected to the lower surface of the pinching handle, and the other end of the spring is connected to the upper surface of the sleeve.

[0011] When the housing needs to be used, the pinch handle is pinched and moved away from the sleeve. The movement of the pinch handle drives the insertion rod to move, and the pinch handle extends the spring, rotating the support block so that the support block is close to the side wall of the housing. The insertion rod is aligned with the insertion hole, and the pinch handle is released. The spring contracts under elastic force and drives the pinch handle toward the sleeve. The movement of the pinch handle causes the insertion rod to be inserted into the insertion hole, thereby fixing the support block. At this time, the housing can be held by hand to grind the teeth to be polished. After polishing is completed, the pinch handle is pinched to remove the insertion rod from the insertion hole, canceling the fixation of the support block, and the two support blocks are rotated by hand to support the housing.

[0012] Furthermore, an arc-shaped sliding groove is formed on the inner side wall of the shell and is located adjacent to the fourth rotating shaft. A slider is slidably installed in the arc-shaped sliding groove, and the fourth rotating shaft is rotatably connected to the slider.

[0013] The rotation of the fourth rotating shaft drives the slider to slide in the arc-shaped sliding groove. The arc-shaped sliding groove and the slider have a guiding effect on the fourth rotating shaft, so that the fourth rotating shaft rotates more smoothly.

[0014] Furthermore, the knob is provided with anti-slip grooves.

[0015] The anti-slip grooves on the knob can increase the friction between the fingers, making it easier to turn the knob.

[0016] Furthermore, anti-slip grooves are provided on the outer side of the shell.

[0017] When the user holds the shell by hand to grind the teeth, the anti-slip grooves on the shell can increase the friction between the shell and the hand, so that the hand can hold the shell more firmly. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention is described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, a teeth grinding device includes a shell 1, a rubber sleeve 3 is provided on the lower side wall of the shell 1, a second rotating shaft 52 is rotatably installed in the rubber sleeve 3, and a teeth grinding column 9 is provided at the outer end of the second rotating shaft 52; a motor 5 is fixedly installed on the upper side wall of the interior of the shell 1, a first rotating shaft 51 is provided inside the shell 1, one end of the first rotating shaft 51 is connected to the output shaft of the motor 5, the other end of the first rotating shaft 51 is fixedly connected to a cross-axis universal joint 7, and the other end of the cross-axis universal joint 7 is connected to the second rotating shaft 52; a first L-shaped mounting plate 6 is fixedly installed on the side wall of the shell 1, and the first rotating shaft 51 penetrates The first L-shaped mounting plate 6 is passed through, and a second L-shaped mounting plate 61 is provided inside the shell 1. The cross-axis universal joint 7 passes through the second L-shaped mounting plate 61. An adjustment component 8 is provided inside the shell 1. The adjustment component 8 is used to adjust the angle of the cross-axis universal joint 7, thereby realizing the angle adjustment of the molar column 9; the outer wall of the shell 1 is symmetrically provided with two fixing seats 4, and a support block 41 is hinged on the fixing seat 4. The outer port of the support block 41 is provided with a plug hole 42. A fixing component 2 is provided above the fixing seat 4 on the outer wall of the shell 1. The adjusting fixing component 2 is used to fix the support block 41 when it is not in use.

[0025] When a patient needs to clean his teeth, he holds the shell 1 by hand, aligns the molar column 9 with the teeth that need to be polished, and starts the motor 5. The output shaft of the motor 5 drives the first rotating shaft 51 to rotate. The rotation of the first rotating shaft 51 drives the cross-axis universal joint 7 to rotate. The rotation of the cross-axis universal joint 7 drives the second rotating shaft 52 to rotate. The rotation of the second rotating shaft 52 drives the molar column 9 to rotate, thereby polishing the teeth that need to be polished. When it is necessary to polish teeth at different positions, adjust the adjustment component 8 so that the cross-axis universal joint 7 rotates, so that the rotation of the cross-axis universal joint 7 drives the second rotating shaft 52 to rotate. At this time, the second L-shaped mounting plate 61 rotates along with the second rotating shaft 52, thereby facilitating the polishing of teeth at different positions. After polishing is completed, when the shell 1 is placed on the table, adjust the fixing component 2 to cancel the plug-in fixation of the support block 41, and rotate the two support blocks 41 by hand. The two support blocks 41 support the shell 1 to prevent the shell 1 from rolling on the table and falling to the ground and causing damage.

[0026] Specifically, the adjustment assembly 8 includes a third rotating shaft 81 and a fourth rotating shaft 84; the third rotating shaft 81 is rotatably mounted on the first L-shaped mounting plate 6, and the installation position of the third rotating shaft 81 is relatively perpendicular to the cross-axis universal joint 7. The third rotating shaft 81 extends to the outside of the shell 1, and the outer end of the third rotating shaft 81 is provided with a knob 83. The third rotating shaft 81 is rotatably sleeved with a first half gear 82 located between the first L-shaped mounting plate 6 and the cross-axis universal joint 7; the fourth rotating shaft 84 is rotatably mounted on the second L-shaped mounting plate 61, and the installation position of the fourth rotating shaft 84 is relatively perpendicular to the cross-axis universal joint 7. The fourth rotating shaft 84 is rotatably sleeved with a second half gear 85, and the second half gear 85 is engaged with the first half gear 82. When the angle of the molar column 9 needs to be adjusted, the knob 83 is turned by hand. The rotation of the knob 83 drives the third shaft 81 to start rotating. The rotation of the third shaft 81 drives the first half gear 82 to rotate. The first half gear 82 engages to drive the second half gear 85 to rotate. The rotation of the second half gear 85 causes the fourth shaft 84 and the second L-shaped mounting plate 61 to start rotating. The rotation of the second L-shaped mounting plate 61 drives the cross-axis universal joint 7 to rotate. The rotation of the cross-axis universal joint 7 drives the second shaft 52 to rotate. The rotation of the second shaft 52 drives the molar column 9 to rotate. At this time, the angle of the molar column 9 can be easily adjusted.

[0027] Specifically, the fixing assembly 2 includes a sleeve 21 and a spring 24; the sleeve 21 is fixedly installed on the outer wall of the shell 1, an insertion rod 22 is inserted in the sleeve 21, and a pinch handle 23 is fixedly installed on the outer end of the insertion rod 22. The spring 24 is sleeved on the insertion rod 22, one end of the spring 24 is connected to the lower surface of the pinch handle 23, and the other end of the spring 24 is connected to the upper surface of the sleeve 21. When the housing 1 is to be used, the handle 23 is pinched and moved away from the sleeve 21. The movement of the handle 23 drives the insertion rod 22 to move, and the movement of the handle 23 causes the spring 24 to extend, rotating the support block 41 so that the support block 41 is close to the side wall of the housing 1. The insertion rod 22 is aligned with the insertion hole 42. The handle 23 is released. The spring 24 is elastically contracted and drives the handle 23 toward the sleeve 21. The movement of the handle 23 causes the insertion rod 22 to be inserted into the insertion hole 42, thereby fixing the support block 41. At this time, the housing 1 can be held by hand to grind the teeth to be polished. After polishing is completed, the handle 23 is pinched to remove the insertion rod 22 from the insertion hole 42, canceling the fixation of the support block 41. The two support blocks 41 are then rotated by hand to support the housing 1.

[0028] Specifically, an arcuate slot 101 is formed on the inner sidewall of the housing 1, adjacent to the fourth rotating shaft 84. A slider 102 is slidably mounted within the arcuate slot 101, and the fourth rotating shaft 84 is rotatably connected to the slider 102. Rotation of the fourth rotating shaft 84 drives the slider 102 to slide within the arcuate slot 101. The arcuate slot 101 and the slider 102 guide the fourth rotating shaft 84, ensuring smoother rotation of the fourth rotating shaft 84.

[0029] Specifically, anti-skid patterns are provided on the knob 83. The anti-skid patterns on the knob 83 can increase the friction between the fingers and the knob 83, making it easier to turn the knob 83 by hand.

[0030] Specifically, the outer side of the housing 1 is provided with anti-skid grooves. When the user holds the housing 1 by hand to polish the teeth, the anti-skid grooves on the housing 1 can increase the friction between the user and the hand, so that the user can hold the housing 1 more firmly.

[0031] The above is a detailed description of the present invention in conjunction with specific embodiments, and the specific implementation methods of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, if a number of equivalent substitutions or obvious modifications are made without departing from the concept of the present invention and the performance or use are the same, they should be considered to fall within the scope of patent protection of the present invention as determined by the submitted claims.
