Technical Field

[0001] This utility model relates to the field of porcelain crown restoration technology, specifically a grinding device for porcelain crown restoration. Background Technology

[0002] Porcelain crowns are restorative crowns used to restore damaged teeth and meet functional and aesthetic requirements. After the porcelain crown is initially shaped, the staff needs to polish it to adjust its shape and other aspects, so that subsequent painting and color fixing can be carried out smoothly.

[0003] When porcelain crowns are being prepared, a grinding device is often used to polish them. Currently, some porcelain crowns are polished by placing the crown in one hand and holding a grinding machine in the other. This process generates a lot of dust, which not only affects the working environment of the workers, but also affects their health if they inhale too much of it. Utility Model Content

[0004] The purpose of this invention is to provide a grinding device for porcelain crown restoration, so as to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for porcelain crown restoration, comprising a handle and a connecting rod, and further comprising:

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 As shown, a grinding device for porcelain crown restoration includes a handle 1 and a connecting rod 2. A drive device is installed inside the handle 1. One end of the connecting rod 2 rotatably passes through the handle 1 and is fixedly connected to the output shaft of the drive device inside. When the drive device is started, the connecting rod 2 rotates with the output shaft of the drive device. This is existing mature technology and is well known to those skilled in the art, so it will not be described in detail here. A protective cover 4 is fixedly connected to the surface of the handle 1. The other end of the connecting rod 2 passes through the protective cover 4 and is fixedly connected to a grinding disc 3. A dust collection frame 5 is fixedly inserted inside the protective cover 4. One side of the dust collection frame 5 is movably mounted... The device has a movable cover 6, and a limiting structure 9 is provided between the movable cover 6 and the dust collection frame 5. The dust collection frame 5 has a groove 8 inside, and a filter plate 7 is detachably connected inside the groove 8. A flexible hose 10 passes through the right side of the movable cover 6. A round cover 11 is fixedly connected to the surface of the protective cover 4. The other end of the flexible hose 10 passes through the surface of the round cover 11. A round cover 12 is provided on the surface of the round cover 11. A threaded structure 13 is provided between the round cover 12 and the round cover 11. Several fan blades 14 are fixedly connected to the surface of the connecting rod 2, and the fan blades 14 are inside the round cover 11. Several exhaust holes 15 are provided on the surface of the round cover 12.

[0024] The limiting structure 9 includes two pressing blocks 92, which are respectively located at the top and bottom of the movable cover 6. Both the top and bottom of the movable cover 6 have pressing grooves 91, and springs 95 are fixedly connected between the pressing grooves 91 and the pressing blocks 92. Limiting frames 93 are fixedly connected to both sides of the surface of the dust collection frame 5, and limiting grooves 94 are formed inside the limiting frames 93. The surface of the pressing block 92 contacts the inner wall of the limiting groove 94. Through the setting of the limiting structure 9, when there is excessive dust on the surface of the filter plate 7 inside the dust collection frame 5 and the movable cover 6, the pressing block 92 will automatically release pressure. The operator applies force to the two pressing blocks 92, causing them to move in the same direction within the two pressing grooves 91. Then, the operator pulls the cover 6 to the right, thereby releasing the relationship between the limiting groove 94 and the pressing blocks 92, making it easier for the operator to remove the filter plate 7 for replacement. After replacing the filter plate 7, the operator applies force to the pressing blocks 92, causing them to re-enter the limiting groove 94. When the pressing blocks 92 are in contact with the inside of the limiting groove 94, the spring 95, due to its elasticity, fixes the pressing blocks 92 inside the limiting groove 94.

[0025] The threaded structure 13 includes an inner groove 131, which is formed on the surface of the round cover 11. The inner wall of the inner groove 131 is provided with an internal thread 132. A threaded sleeve 133 is fixedly connected to the surface of the round cover 12. With the setting of the threaded structure 13, when there is too much dust on the inner wall of the round cover 11 and the surface of several fan blades 14, the internal thread 132 fixedly connected to one side of the inner groove 131 is used to rotate the threaded sleeve 133 fixedly connected to the surface of the round cover 12. When the threaded sleeve 133 has rotated completely, the round cover 12 can be disassembled from the inside of the round cover 11, so that the staff can clean the dust inside the round cover 11 and the surface of several fan blades 14.

[0026] Several resistance blocks 16 are fixedly connected to the outer ring surface of the round cover 12. The surface of the resistance blocks 16 is arc-shaped. By setting the resistance blocks 16, the resistance on the round cover 12 can be increased when the operator rotates the round cover 12, so that the operator can apply force to rotate the round cover 12. At the same time, the arc-shaped setting of the resistance blocks 16 makes it easier for the operator to apply force to the round cover 12.

[0027] A fixing block 17 is fixedly connected to the right side of the protective cover 4, and the hose 10 is fixedly passed through the fixing block 17. The fixing block 17 provides support and fixation for the hose 10 during use.

[0028] The movable cover 6 has a storage slot 18 inside, and the area of ​​the longitudinal section of the storage slot 18 is larger than the area of ​​the longitudinal section of the groove 8. The storage slot 18 can fix the filter plate 7 when it is placed in the storage slot 18.

[0029] It should be noted that the handle 1, connecting rod 2 and grinding disc 3 mentioned in this solution are all existing technologies. The specific structure, working principle and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0030] Working Principle: When using this polishing device, the output shaft of the drive device inside the handle 1 rotates, which in turn drives the connecting rod 2 to rotate, causing the polishing disc 3, which is fixedly connected to the surface of the connecting rod 2, to rotate as well, thereby polishing the porcelain crown. During the polishing process, the rotation of the connecting rod 2 drives several fan blades 14 on its surface to rotate. At this time, several exhaust holes 15 opened on the surface of the round cover 12 drive the airflow inside the round cover 11. As the fan blades 14 rotate, a negative pressure is generated inside the round cover 11, and dust can be sucked in through the groove 8 inside the dust collection frame 5. In order to reduce dust entering the interior of the round cover 11 through the hose 10, a removable filter plate 7 is placed in the storage slot 18 inside the movable cover 6, thereby reducing dust entering the interior of the round cover 11 through the hose 10 during the dust absorption process. When too much dust is sucked in, this... When the operator applies force to the two pressing blocks 92, the two pressing blocks 92 move in the same direction within the two pressing grooves 91. Then, the operator pulls the cover 6 to the right, thereby releasing the relationship between the limiting groove 94 and the pressing blocks 92, making it easier for the operator to remove the filter plate 7 for replacement. After replacement, the pressing blocks 92 can be pressed again to enter the interior of the limiting groove 94. When the pressing blocks 92 are in contact with the interior of the limiting groove 94, the elasticity of the spring 95 fixes the pressing blocks 92 inside the limiting groove 94. When there is too much dust inside the round cover 11 and the fan blade 14, the operator needs to rotate the round cover 12. At this time, the resistance block 16 fixedly connected to the outer ring of the round cover 12 makes it easy for the operator to apply force to the round cover 12. Then, through the threaded structure 13 between the round cover 12 and the round cover 11, the round cover 12 can be easily removed for cleaning of the internal dust.
