[0002] A dental grinder is a grinding device used for grinding and polishing dentures. It can be used to repair the wear on the surface of dentures. After grinding the worn parts, the worn parts can be repaired again to make the denture surface more beautiful and the denture can be used normally.

[0003] The existing dental grinder is generally composed of a grinding component and a hand rest. The grinding component is used to grind dentures, and the hand rest is used to support the operator's arm. During the operation, one hand is required to hold the denture and the other hand to use the grinding component to work. The comfort level felt by different human bodies is not the same. Most of the existing hand rests can only support the operator's arm at a fixed angle. During long-term work, the operator's arms are easily sore and tired, thereby affecting the actual production efficiency. In this regard, the present application provides a dental grinder to solve the above problems. Utility Model Content

[0004] In response to the deficiencies in the prior art, the present application provides a dental grinder having the advantages of being able to support the operator's arm at different angles, thereby overcoming the shortcoming that the hand rest of the existing dental grinders is mostly at a fixed angle and cannot meet the operator's adjustment needs.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a dental grinder, comprising a grinder body, a grinding mechanism for grinding dentures is installed on the top of the grinder body, and a hand support assembly for supporting an arm is installed on the outer side of the grinder body;

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0029] See also Figure 1-3The present application provides a technical solution: a dental grinder, comprising a grinder body 1, a grinding mechanism 200 for grinding dentures is installed on the top of the grinder body 1, and a hand rest assembly 300 for supporting the arm is installed on the outside of the grinder body 1; through the coordinated use of the grinding mechanism 200 on the top of the grinder body 1 and the hand rest assembly 300 on the outside, the operator's arm can be supported at different angles, and the horizontal position can be adjusted, thereby further improving the adaptability space of the arm load, allowing most operators to perform denture grinding work in a relatively comfortable posture, reducing the soreness and swelling of the arms after long-term work, thereby indirectly improving production efficiency, and effectively improving the practical performance of the dental grinder.

[0030] In this embodiment, the hand rest assembly 300 is a structure used to support the arm during work.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the hand support assembly 300 includes two support plates 301 respectively fixed on both sides of the grinder body 1, a raising plate 302 fixed on the top of the support plate 301, a fixed block 303 fixed on the top of the front of the raising plate 302, a rotating rod 304 rotatably connected to the top of the fixed block 303 through a bearing, a hand screw 305 threadedly connected to the front side of the fixed block 303, a rotating block 306 fixed to the top of the rotating rod 304, an adjustment slot 307 opened at the top of the rotating block 306, an adjustment rod 308 rotatably connected to the inner side of the adjustment slot 307 through a bearing, a disc block 309 fixed to the outside of the adjustment rod 308, a hand support plate 310 fixed to the top of the disc block 309, a plurality of limiting slots 311 opened on the back side of the outer side of the disc block 309, an elastic member 312 fixed to the back of the rotating block 306, a connecting plate 313 fixed to the back side of the elastic member 312, and a limiting rod 314 fixed to the front side of the connecting plate 313.

[0032] It should be noted that one end of the back side of the hand screw 305 passes through the front side of the corresponding fixed block 303 and abuts against the outer side of the corresponding rotating rod 304, so that the hand screw 305 can apply pressure to the rotating rod 304 to position it, and the adjustment groove 307 allows the corresponding disc block 309 to rotate. The hand support plate 310 is located above the rotating block 306, so that the hand support plate 310 can drive the disc block 309 to rotate normally.

[0033] In addition, the bottom of the rotating block 306 fits with the top of the corresponding fixed block 303, and both the bottom of the rotating block 306 and the top of the fixed block 303 are smooth. The bottom end of the rotating rod 304 passes through the bottom of the corresponding fixed block 303, so that the rotating block 306 can rotate stably under the action of the rotating rod 304.

[0034] At the same time, the top opening of the limit slot 311 is arc-shaped, and the end of the limit rod 314 close to the disc block 309 passes through the outer side of the corresponding rotating block 306 and is inserted into the inner side of the corresponding limit slot 311. The front end of the top of the limit rod 314 is an inclined surface, and the bottom of the limit rod 314 is a plane, so that when the limit slot 311 rotates downward, it can push the inclined surface of the limit rod 314 under the action of the arc-shaped opening to move the limit rod 314, which is convenient for the angle adjustment work. Under the action of the bottom plane of the limit rod 314, when the limit slot 311 moves toward the front side, the bottom of the limit slot 311 abuts against the bottom of the limit rod 314, which plays a limiting role, so that the hand support plate 310 cannot be pressed down, thereby providing good support for the arm.

[0035] In addition, the limiting rod 314 is located at the inner side of the corresponding elastic member 312 , and the elastic member 312 is a spring, so that the elastic member 312 can be stably stretched under the action of the limiting rod 314 .

[0036] In this embodiment, the grinding mechanism 200 is a structure for grinding the denture.

[0037] like Figure 1 As shown, the grinding mechanism 200 includes a mounting rod fixedly mounted on the top of the grinder body 1, a positioning slider sleeved on the outside of the mounting rod and used for installation, a slide cylinder hinged to the front of the positioning slider through a pin, a mounting piece hinged to the front of the slide cylinder through a pin, and a grinder fixedly mounted on the front of the mounting piece.

[0038] It should be noted that the grinder includes a square block fixedly connected to the front of the mounting piece, a driving motor fixedly mounted on the top of the square block, a grinding rod fixedly mounted on the output shaft of the driving motor and passing through the top of the square block, the top of the grinding rod is rotatably connected to the bottom of the square block through a bearing, and the grinding rod is located directly above the grinder body 1, so that the driving motor can drive the grinding rod to rotate. At the same time, under the rotational movement of the two hinges of the slide and the mounting piece, the position of the grinding rod can be changed, which is convenient for the normal grinding work. The grinding mechanism 200 is an existing public technology, so it will not be described in detail.

[0039] The working principle of the above embodiment is:

[0040] When performing denture grinding, the hand support plate 310 is lifted upward, so that the disc block 309 rotates through the adjusting rod 308, and the position of the corresponding limiting groove 311 is changed, so that the top of the limiting rod 314 is pushed, and the elastic member 312 is stretched. Under the elastic force recovery action of the elastic member 312, the limiting rod 314 is driven to be inserted into the inner side of the adjacent limiting groove 311 through the connecting plate 313, and the hand support plate 310 is adjusted to an angle convenient for working. When the arm is placed on the top of the hand support plate 310 and pressed down, the limiting groove 311 is driven to move. 11 moves toward the front side so that the inner wall of the limiting groove 311 abuts against the bottom of the limiting rod 314. Under the limiting effect of the bottom of the limiting rod 314, the hand support plate 310 cannot be pressed down, which can provide good support for the arm. Loosen the hand screw 305 and rotate the hand support plate 310 to change the lateral position of the hand support plate 310. Tighten the hand screw 305 to apply pressure on the outer side of the rotating rod 304 to position the hand support plate 310. Start the grinding mechanism 200 to grind the denture.

[0041] Compared with the prior art, the dental grinder, through the coordinated use of the grinding mechanism 200 on the top of the grinder body 1 and the hand rest assembly 300 on the outside, can support the operator's arm at different angles and can also adjust the position laterally, thereby further improving the adaptability of the arm load, allowing most operators to perform denture grinding work in a relatively comfortable posture, reducing the soreness of the arms after long-term work, thereby indirectly improving production efficiency, and effectively improving the practical performance of the dental grinder, solving the problem that the hand rest part of the existing dental grinder is mostly fixed at a fixed angle and cannot meet the adjustment needs of the operator.

[0042] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The provision of power supply is common knowledge in the field. The main controller can be a conventional known device for control such as a computer, which can be realized through simple programming by technicians in the field. They are all existing public power connection technologies and will not be described in detail in the article.
