Description

Technical Field

[0001] This utility model belongs to the field of dental prosthesis testing technology, and specifically relates to a dental prosthesis testing fixture. Background Technology

[0002] Dentures, also known as prostheses, are a general term in medicine for restorations made after partial or complete loss of the upper and lower jaws. Dentures achieve retention and stability with the help of retainers and bases, and are used to restore missing teeth and adjacent soft and hard tissues. It is a method of tooth restoration. After the denture is completed, a special instrument is needed to test the position of the denture. Only after the test is passed can the denture be used.

[0003] Existing patent CN 210009167U discloses a rapid denture testing fixture, including a base, a support rod disposed on the base, and a testing part for testing the molar position of the denture. The base is provided with a clamping device, and a clamp for fixing the denture is fixed on the clamping device. The clamp includes a rotating disk one and a rotating disk two disposed on the upper surface of the rotating disk one and rotatably connected to the rotating disk one. The upper surface of the rotating disk two has a plurality of fixing holes arranged in a circle and used in conjunction with the testing part.

[0004] Although the aforementioned denture testing fixture can perform continuous testing for a period of time, it is still necessary to pause the testing process after all the dentures on the turntable have been tested, and place the next batch of dentures to be tested on the turntable. Therefore, it cannot achieve truly continuous testing operations.

[0005] Therefore, it is necessary to provide a dental prosthesis testing fixture to address the aforementioned technical problems.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] The purpose of this invention is to provide a dental prosthesis testing fixture that can solve the problem that existing dental prosthesis testing fixtures cannot achieve continuous testing operations.

[0008] To achieve the above objectives, a specific embodiment of this utility model provides the following technical solution: a denture testing fixture, comprising: an operating table, a testing mechanism, a denture placement device, and an upward pushing mechanism.

[0009] A support column is fixed to the operating platform, and a rotating arm is rotatably mounted on the support column. The detection mechanism is installed at the end of the rotating arm away from the support column. The denture placement device is installed on the operating platform on one side of the support column. The denture placement device includes: a main turntable, multiple denture placement slots, a denture ejection assembly, and a material storage assembly. A main shaft is fixed to the bottom of the main turntable and rotates on the operating platform. The multiple denture placement slots are evenly carved on the main turntable, and the denture ejection assembly is slidably disposed within the denture placement slots. The material storage assembly is located on one side of the main turntable, with one end of it positioned above one of the denture placement slots.

[0010] The denture ejection assembly includes a slide rod and an upper pusher. The slide rod slides on the denture placement slot, and the denture placement slot has a groove adapted to the slide rod. The upper pusher is rotatably mounted on one end of the slide rod located within the denture placement slot. The upper pusher mechanism is slidably mounted on the operating table and is located directly below one of the denture placement slots.

[0011] In one embodiment of this utility model, the material storage assembly includes: a receiving head, a conveying chute, and a storage box. The receiving head is located above one of the denture placement slots and the upper end of the pushing mechanism, and a through hole corresponding to the pushing head is drilled on the bottom wall of the receiving head. The pushing head pushes the denture that has been inspected into the receiving head, and then it slides down into the storage box through the conveying chute.

[0012] In one embodiment of this utility model, a rotating head is fixed to the bottom of the upper push head, and the rotating head is rotatably connected to the slide rod. The upper push head is rotatably connected to the slide rod through the rotating head.

[0013] In one embodiment of this utility model, the upper push head is provided with a circular protrusion, and the through hole is provided with a groove that matches the circular protrusion. By providing the circular protrusion and the groove, when the slide rod drives the upper push head to move upward, the upper push head will not pass through the through hole, thereby allowing the upper push head to rotate.

[0014] In one embodiment of this utility model, the pushing mechanism includes a push rod, an auxiliary turntable, and a control component. The push rod is slidably mounted on the operating table. The auxiliary turntable is fixed to one end of the main shaft located at the bottom of the operating table. The control component is fixed to the outside of the auxiliary turntable and corresponds to the positions of multiple denture placement slots. The main shaft drives the auxiliary turntable to rotate, and the auxiliary turntable drives the push rod to move up and down via the control component.

[0015] In one embodiment of this utility model, a top head is fixed to the upper end of the push rod, and a spring is installed on the push rod between the top head and the operating table. A plurality of sliding rods are each fixed to a corresponding fixing block at one end of the bottom of the main turntable. The spring force pushes the top head and push rod upwards, and the top head pushes the sliding rods upwards through the fixing blocks.

[0016] In one embodiment of this utility model, a pulley is installed at one end of the push rod at the bottom of the operating table. The pulley slides on the control component. By sliding the pulley on the control component, when the auxiliary turntable drives the control component to rotate, the pulley drives the push rod to move downward.

[0017] In one embodiment of this utility model, a limiting groove is chiseled on the push rod, and a limiting block adapted to the limiting groove is fixed on the operating table. The push rod slides on the limiting block through the limiting groove, thereby preventing the push rod from rotating.

[0018] In one embodiment of this utility model, a damping mechanism is also fixed on the operating table around the push rod. The damping mechanism plays a damping role, and when the spring force pushes the top and the push rod to move upward, it moves upward slowly to prevent the instantaneous release of the spring force from making the denture in the denture placement slot fly out.

[0019] In one embodiment of this utility model, a transmission wheel is fixed at the end of the main shaft away from the main turntable. The transmission wheel is used to connect with an external drive device and drive the main shaft to rotate.

[0020] Compared with the prior art, the dental prosthesis testing fixture of this utility model, by setting an automatic material discharge structure, realizes continuous operation of the dental prosthesis testing fixture, effectively improving the testing efficiency. Attached Figure Description

Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0033] like Figures 1 to 8 As shown, a denture testing fixture in one embodiment of the present invention includes: an operating table 1, a testing mechanism 103, a denture placement device 2, and an upward pushing mechanism.

[0034] A support column 101 is fixed on the operating table 1, and a rotating arm 102 is rotatably mounted on the support column 101. A detection mechanism 103 is installed at the end of the rotating arm 102 away from the support column 101. A denture placement device 2 is installed on the operating table 1 and located on one side of the support column 101. The denture placement device 2 includes: a main turntable 201, multiple denture placement slots 206, a denture ejection assembly, and a material storage assembly 205. A main shaft 202 is fixed to the bottom of the main turntable 201 and rotates on the operating table 1. The multiple denture placement slots 206 are evenly carved on the main turntable 201, and the denture ejection assembly is slidably disposed within the denture placement slots 206. The material storage assembly 205 is located on one side of the main turntable 201, and one end of it is located on the upper end of one of the denture placement slots 206.

[0035] The denture ejection assembly includes a slide rod 209 and an upper pusher 208. The slide rod 209 slides on the denture placement slot 206, and the denture placement slot 206 has a groove 207 adapted to the slide rod 209. The upper pusher 208 is rotatably mounted on one end of the slide rod 209 located in the denture placement slot 206. The upper pusher mechanism is slidably mounted on the operating table 1 and is located directly below one of the denture placement slots 206.

[0036] In use, the denture to be tested is placed into the denture placement slot 206, and then the main shaft 202 is rotated by an external drive device. The main shaft 202 drives the main turntable 201 to rotate intermittently. When the main turntable 201 rotates the denture to the bottom of the testing mechanism 103, the denture is tested by the testing mechanism 103. After the test is completed, the main turntable 201 moves the denture to the bottom of the receiving head 212, and pushes the slide rod 209 upward by the push rod 216. The slide rod 209 pushes the denture out of the denture placement slot 206 and into the storage assembly 205 through the upper push head 208. During the operation, only one operator needs to place the dentures to be tested one by one into the denture placement slot 206 to achieve continuous testing.

[0037] The slide 207 is a rectangular slide perpendicular to the axis of the main turntable 201. By setting the slide 207 as a rectangular slide, rotation is prevented when the slide rod 209 drives the upper push head 208 to move upward. In addition, because the slide 207 is perpendicular to the axis of the main turntable 201, after the slide rod 209 drives the upper push head 208 to move up and down and contact the receiving head 212, the direction of rotation of the upper push head 208 is on the same vertical horizontal plane as the oblique direction of the conveying slide 213, so that the denture that has been inspected slides into the storage box 214 along the conveying slide 213.

[0038] like Figures 4 to 6As shown, the storage assembly 205 includes a receiving head 212, a conveying chute 213, and a storage box 214. The receiving head 212 is located at the upper end of one of the denture placement slots 206 and the pushing mechanism, and a through hole 215 corresponding to the pushing head 208 is drilled on the bottom wall of the receiving head 212. The pushing head 208 pushes the inspected denture into the receiving head 212, and then it slides down into the storage box 214 through the conveying chute 213.

[0039] like Figures 4 to 6 As shown, a rotating head 210 is fixed to the bottom of the upper push head 208, and the rotating head 210 is rotatably connected to the slide rod 209. The upper push head 208 is rotatably connected to the slide rod 209 through the rotating head 210. The upper push head 208 is provided with a circular protrusion, and a groove adapted to the circular protrusion is provided at the through hole 215. By providing the circular protrusion and the groove, when the slide rod 209 drives the upper push head 208 to move upward, the upper push head 208 will not pass through the through hole 215, thereby allowing the upper push head 208 to rotate.

[0040] like Figures 5 to 7 As shown, the pushing mechanism includes a push rod 216, an auxiliary turntable 204, and a control component 219. The push rod 216 is slidably mounted on the operating table 1. The auxiliary turntable 204 is fixed to one end of the main shaft 202 located at the bottom of the operating table 1. The control component 219 is fixed to the outside of the auxiliary turntable 204 and corresponds to the positions of multiple denture placement slots 206. The main shaft 202 drives the auxiliary turntable 204 to rotate, and the auxiliary turntable 204 drives the push rod 216 to move up and down via the control component 219.

[0041] like Figures 5 to 7 As shown, a top head 217 is fixed to the upper end of the push rod 216. A spring 223 is installed on the push rod 216 between the top head 217 and the operating table 1. Multiple sliding rods 209 are located at one end of the bottom of the main turntable 201, and each end is fixed with a fixing block 211 corresponding to the top head 217. The elastic force of the spring 223 pushes the top head 217 and the push rod 216 upward, and the top head 217 pushes the sliding rods 209 upward through the fixing blocks 211.

[0042] like Figures 3 to 7As shown, a pulley 218 is installed at one end of the push rod 216 at the bottom of the operating table 1. The pulley 218 slides on the control component 219. By sliding the pulley 218 on the control component 219, when the auxiliary turntable 204 drives the control component 219 to rotate, the pulley 218 drives the push rod 216 to move downward. A limiting groove 220 is carved on the push rod 216. A limiting block 221 that matches the limiting groove 220 is fixed on the operating table 1. The limit rod 216 slides on the limiting block 221 through the limiting groove 220, thereby preventing the push rod 216 from rotating. A damping mechanism 222 is also fixed on the operating table 1 around the push rod 216. The damping mechanism 222 acts as a damper. When the spring force of the spring 223 pushes the top head 217 and the push rod 216 to move upward, the push rod 216 moves upward slowly, preventing the instantaneous release of the spring force from knocking the denture in the denture placement slot 206 out.

[0043] like Figures 2 to 5 As shown, a transmission wheel 203 is fixed at one end of the main shaft 202 away from the main turntable 201. The transmission wheel 203 is used to connect with an external drive device and drive the main shaft 202 to rotate.

[0044] Working Principle: In use, the transmission wheel 203 is connected to an external drive device, driving the main shaft 202 to rotate. The main shaft 202 drives the main turntable 201 to rotate intermittently. When the main turntable 201 rotates the denture to the bottom of the detection mechanism 103, the denture is detected. After detection, the main turntable 201 moves the denture to the bottom of the receiving head 212. Simultaneously with the rotation of the main shaft 202, the auxiliary turntable 204 drives the control component 219 to rotate. The rotation of the control component 219 drives the push rod 216 downwards via the pulley 218. After the push rod 216 moves downwards, the upper push head 208 and the sliding rod 209 move downwards due to their own gravity, causing the upper push head 208 to slide back into the denture placement slot 206.

[0045] When the next denture placement slot 206 moves directly below the receiving head 212, the pulley 218 moves to the top of the control component 219. At this time, due to the elastic force of the spring 223, the push rod 216 and the top head 217 move upward. The top head 217 drives the slide rod 209 to move upward through the fixing block 211. The slide rod 209 pushes the denture out of the denture placement slot 206 through the upper push head 208, so that the denture passes through the through hole 215 and moves into the receiving head 212. After the upper push head 208 contacts the bottom wall of the receiving head 212, it rotates, causing the denture on it to slide downward along the conveying chute 213 into the storage box 214.

[0046] During the operation, only one operator needs to place the dentures to be tested one by one into the denture placement slot 206 to achieve continuous testing.

[0047] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this disclosure. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0048] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
