Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis processing technology, specifically a zirconia dental prosthesis grinding device. Background Technology

[0002] Zirconia dentures are dental restorations made from zirconia. Zirconia, with the chemical formula ZrO2, is widely used in dentistry due to its excellent mechanical properties, biocompatibility, and aesthetics. It possesses high strength and wear resistance, while its color closely resembles natural teeth, providing a very natural appearance.

[0003] The zirconia denture polishing device is a specialized device for fine adjustment and polishing of zirconia restorations. Due to the extremely high hardness of zirconia, ordinary polishing tools are insufficient for effective processing. Therefore, a specially designed polishing device and tools are required to ensure the restoration achieves the desired shape, fit, and aesthetics. Existing handheld polishing devices require manual holding of the handle to polish the denture. However, this method of holding the handle excessively can easily cause excessive bending and damage to the connecting wires. Furthermore, placing the denture directly on a table after polishing can easily cause the handle to fall and be damaged. Therefore, we propose a zirconia denture polishing device.

[0016] 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.

[0017] Please see Figures 1-3 This utility model provides a technical solution: a zirconia denture grinding device, including a work box 1, a number of support bases 3 made of rubber material fixedly connected to the bottom of the work box 1, a protective frame 2 fixedly installed on the outside of the work box 1, a connection interface 4 provided on one side of the work box 1, an anti-bending mechanism 5 for preventing bending and damage to the grinding handle connection harness threadedly connected to one side of the connection interface 4, and a grinding handle bearing mechanism 6 for bearing the grinding handle fixedly installed on the top of the protective frame 2.

[0018] The rubber support base 3 prevents the work box 1 from shifting during use. The connecting harness of the external grinding handle is inserted into the connection interface 4. The anti-bending mechanism 5 is set outside the connecting harness and threaded onto the outside of the connection interface 4. This design prevents the connecting harness from bending excessively when the handle is held and pulled, and also prevents the connecting harness from detaching from the connection interface 4. The grinding handle bearing mechanism 6 can store the grinding handle and can tilt the grinding handle, making it easier to pick up and put down the grinding handle.

[0019] Please see Figure 1 and Figure 2 The anti-bending mechanism 5 includes an external threaded sleeve 7, a connecting piece 8, an internal threaded sleeve 9, and a locking head 10. The external threaded sleeve 7 is fixedly installed on the outside of the connecting interface 4. The internal threaded sleeve 9, which is threadedly connected to the external threaded sleeve 7, is rotatably connected to one side of the connecting piece 8. An elastic connector 20 is fixedly connected to the side of the connecting piece 8 away from the internal threaded sleeve 9. The locking head 10 is fixedly connected to one end of the elastic connector 20.

[0020] The locking head 10 is installed on the outside of the connecting wire harness, and then the internal threaded sleeve 9 and the external threaded sleeve 7 are threaded together. This arrangement allows the connecting wire harness to be guided by the elastic connector 20 when it is pulled, thus protecting the connecting wire harness from detaching from the connecting interface 4 when it is pulled, and preventing the connecting wire harness from being damaged by excessive bending.

[0021] Please see Figure 1 and Figure 3The grinding handle support mechanism 6 includes a positioning post 11, a base plate 12, a first support frame 14, and a second support frame 15. Two sets of positioning posts 11 are fixedly installed on the top of the protective frame 2. Positioning grooves 13 are opened on the base plate 12 at positions corresponding to the positioning posts 11. The first support frame 14 and the second support frame 15 with different heights are fixedly installed on the top of the base plate 12. Placement grooves 16 are opened on both the first support frame 14 and the second support frame 15. A first blocking plate 17 is fixedly installed on one side of the second support frame 15.

[0022] The first support frame 14 and the second support frame 15, which are of different heights, can be tilted when the grinding handle is placed inside the placement slot 16, making it easier to pick up and put in the grinding handle. The first blocking plate 17 can limit the bottom of the grinding handle. When the base plate 12 is installed, it can be positioned by interlocking the positioning pin 11 and the positioning slot 13. This installation method can change the left and right positions of the first support frame 14 and the second support frame 15 according to the user's usage habits.

[0023] Please see Figure 1 A winding seat 18 is fixedly installed on one side of the protective frame 2, and a second blocking piece 19 is fixedly connected to the side of the winding seat 18 away from the protective frame 2. Both sides of the winding seat 18 are set to be arc-shaped.

[0024] When placing the grinding handle, excess connecting wires can be collected by winding them around the outside of the winding seat 18. The second blocking piece 9 prevents the connecting wires from detaching from the surface of the winding seat 18. The curved sides of the winding seat 18 prevent excessive bending and deformation of the connecting wires during installation.

[0025] Please see Figure 1 The protective frame 2 is made of aluminum. A frustum-shaped guide boss is fixedly installed on the top of the positioning post 11. The aluminum protective frame 2 can provide rigidity while allowing the heat generated by the working box 1 to dissipate quickly. The frustum-shaped guide boss above the positioning post 11 can facilitate the insertion of the positioning post 11 into the positioning groove 13.

[0026] In use, firstly, the rubber support base 3 prevents the work box 1 from shifting during use. The external grinding handle's connecting harness is inserted into the connection interface 4. An anti-bending mechanism 5 is located outside the connecting harness and threaded onto the connection interface 4. This design prevents excessive bending of the connecting harness when the handle is pulled and prevents it from detaching from the connection interface 4. The grinding handle support mechanism 6 stores the grinding handle and allows it to be tilted for easier handling. A locking head 10 is installed outside the connecting harness, and then the internal threaded sleeve 9 and external threaded sleeve 7 are threaded together. This design allows the connecting harness to be guided by the elastic connector 20 when pulled, thus protecting the connecting harness from strain. The grinding handle connecting harness is disconnected from the connecting interface 4, preventing excessive bending and damage to the connecting harness. The first support frame 14 and the second support frame 15, which are of different heights, can be tilted when the grinding handle is placed inside the placement slot 16, making it easier to pick up and place the grinding handle. The first blocking plate 17 can limit the bottom of the grinding handle. When the base plate 12 is installed, it can be positioned by interlocking the positioning pin 11 and the positioning slot 13. This installation method can change the left and right positions of the first support frame 14 and the second support frame 15 according to the user's usage habits. When placing the grinding handle, excess connecting harness can be collected by winding it around the outside of the winding seat 18. The second blocking plate 9 can prevent the connecting harness from detaching from the surface of the winding seat 18. The curved sides of the winding seat 18 can prevent excessive bending and deformation of the connecting harness during installation.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
