[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.
[0023] Please refer to Figures 1-4, the utility model designs an internal support component suitable for the base of an oral cavity CT. This component includes a flange 1, at the center of whose top is fixedly connected a first hollow cylindrical shell 3. The top of this cylindrical shell can be slidably connected to another hollow cylindrical shell 4. There is a wire routing hole 9 in the middle of the top of this cylindrical shell, and there are also four wire passing holes 2 arranged in a rectangle at its top. There are also four such wire passing holes at the top of the flange 1. On one side of the first hollow cylindrical shell 3, there is a rectangular - shaped threaded hole 6 located at the top of the flange 1. In addition, a waterproof bracket 7 is provided at the connection part between the flange 1 and the first hollow cylindrical shell 3. The threaded hole 6 near the top of the hollow cylinder of the inner support plate can be used for the installation of the slip ring 8, and its internal chamber can be used as the wire guiding path for the wire harness coming out of the inner circle of the slip ring 8. The flange 1 at the bottom has a hole for the wire harness coming out of the inner circle of the slip ring 8 to pass through. The internal support component of the utility model provides a stable basic support through the flange 1. The first hollow cylindrical shell 3 fixedly connected to the center of the top of the flange 1 forms a sliding connection structure, allowing the second hollow cylindrical shell 4 at the top to achieve height adjustment through sliding connection, thus providing flexibility for the cable wiring requirements of different heights. There are multiple wire passing holes at the tops of the first hollow cylindrical shell 3 and the second hollow cylindrical shell 4. These holes not only ensure the orderly arrangement and fixation of the cable wire harnesses, but also further optimize the guidance and protection of the cables through the wire routing hole 9 in the middle of the top. There is a rectangular - shaped threaded hole 6 on one side of the first hollow cylindrical shell 3, located at the top of the flange 1, providing a reliable position for the installation of the slip ring 8. A waterproof bracket 7 is provided at the connection part between the flange 1 and the first hollow cylindrical shell 3. This design greatly enhances the waterproof performance of the component, ensuring the safety and reliability of the cable wire harnesses inside the device in a humid environment. The threaded hole 6 near the top of the hollow cylinder of the inner support plate provides convenience for the installation of the slip ring 8, and its internal chamber can effectively guide the wire harness coming out of the inner circle of the slip ring 8 so that it can smoothly pass through the hole opened at the bottom of the flange 1. The slip ring 8 realizes the connection between the device and the external power supply and control system through the wire guiding path of the inner circle, enabling the entire oral cavity CT base system to operate stably and reliably in a complex environment.
[0024] The surface of the waterproof bracket 7 is provided with a number of wire grooves 10. The design of these wire grooves is aimed at providing a neat and reasonable routing path for the cables passing through the waterproof bracket 7, ensuring that the cables will not cross or tangle when passing through the waterproof bracket 7, thereby reducing the risk of cable damage and improving the stability and reliability of the overall system. In addition, the waterproof bracket 7 is made of polytetrafluoroethylene material, which has excellent waterproof performance and chemical corrosion resistance, enabling the waterproof bracket 7 to still maintain good performance in a humid or water-containing environment, providing effective waterproof protection for the cables inserted into it, preventing moisture from seeping into the cable interior and causing electrical system failures or short circuits, and ensuring the stable operation of the oral CT equipment under different environmental conditions. The waterproof bracket 7 not only ensures the orderly routing of the cables in terms of structural design, but also maximizes the waterproof performance and durability in terms of material selection, and is suitable for various harsh usage environments.
[0025] A first insulating pad 5 is laid on the top end of the second hollow cylindrical shell 4. This insulating pad can not only effectively isolate the electrical connection between the electrical equipment and its supporting components, but also provide additional mechanical support and buffering during the operation of the entire system, preventing damage to the internal electrical circuits of the equipment caused by mechanical vibration or other external factors. At the same time, a second insulating pad 14 is also laid at the connection between the bottom end of the first hollow cylindrical shell 3 and the flange 1. This design enables the electrical system to be fully insulated at every key node of the physical connection, preventing current leakage or electrical short - circuit. These insulating pads are all made of rubber material. The rubber material has good electrical insulation performance and heat - resistant performance, can maintain its physical properties unchanged within a wide temperature range, and can also resist external chemical corrosion. This enables the insulating pads to not only provide electrical insulation protection stably for a long time, but also improve the overall durability and safety of the system to a certain extent. The insulating pads provide insulation protection for the cables passing through the first hollow cylindrical shell 3 and the second hollow cylindrical shell 4. Such a design takes into account various interferences that the cables may be subjected to when operating in a complex electromagnetic environment. By adding insulating pads at key nodes, it not only effectively isolates the electrical connection between the electrical equipment and the supporting components, avoids equipment failures caused by electrical leakage, but also reduces the influence of external electromagnetic interference on the internal circuit to a certain extent, further improving the stability and reliability of the system operation. In addition, the flexibility and elasticity of the rubber material enable the insulating pads to effectively buffer external vibrations and impacts during equipment operation, preventing these mechanical stresses from being transmitted to the internal electrical circuits, thereby protecting the electrical components and connectors from damage. The waterproof property of the insulating pads also ensures that the electrical system is not eroded by external moisture or dirt when used in a humid or dusty environment, thus extending the service life and maintenance cycle of the equipment. Overall, the design of the insulating pads not only enhances the electrical safety of the equipment, but also provides multiple guarantees in terms of mechanical protection, waterproofing and durability, enabling the entire dental CT system to operate efficiently and reliably under various complex working conditions.
[0026] A limiting ring 11 is provided at the top of the outer side of the first hollow cylindrical shell 3. The surface of the limiting ring 11 is threadedly connected with four bolts 12 arranged in a rectangle. The four bolts 12 are threadedly connected to the four threaded holes 6 respectively. When the user twists the bolts 12, the threads on the surface of the bolts 12 match the threads on the inner walls of the threaded holes 6, so that the limiting ring 11 is fixed to the first hollow cylindrical shell 3. This design ensures that the limiting ring 11 can be firmly fixed to the top of the first hollow cylindrical shell 3, thereby effectively preventing it from loosening or shifting during use. The presence of the limiting ring 11 provides additional stability for the first hollow cylindrical shell 3, especially in the case of various mechanical stresses and vibrations that may be suffered during the operation of the equipment. The limiting ring 11 is tightly connected with the bolts 12 and the threaded holes 6 to ensure that it is stable on the first hollow cylindrical shell 3 without displacement, which not only helps to improve the mechanical properties of the entire system Mechanical stability, but also to a certain extent prevents equipment damage caused by vibration or stress. In addition, the design of the limit ring 11 also takes into account the convenience of installation and maintenance. Through the connection between the bolt 12 and the threaded hole 6, the user can easily install or remove the limit ring 11, thereby providing great convenience during equipment maintenance and maintenance. This design not only improves the reliability of the equipment, but also simplifies the operating process, making the equipment more efficient and safe in actual use. At the same time, the close connection between the limit ring 11 and the first hollow cylindrical shell 3 also ensures that the cables and other electrical components distributed inside can remain stable and not be disturbed by the outside world, thereby further improving the overall performance and service life of the equipment. Such a design embodies comprehensive considerations in terms of structural stability, ease of use and equipment safety, so that the equipment can operate more reliably and extend its service life in actual applications.
[0027] Gaskets 13 are laid at the joints of the four bolts 12 and the limit ring 11. The gaskets 13 are made of rubber material. The gaskets 13 provide anti-friction protection for the joints between the bolts 12 and the limit ring 11. This design not only increases the durability of the joints, but also effectively reduces the metal fatigue or wear that may be caused by the tightening of the bolts, ensuring that the limit ring 11 can remain stable and firm during long-term use. At the same time, a slip ring 8 is installed at the bottom end of the outer side of the first hollow cylindrical shell 3. A part of the wire harness leading out from the inner circle of the slip ring 8 can be led out of the device through the opening of the bottom flange 1 of the inner support plate and connected to the mains power, computer, etc. outside the CT device, so as to realize the introduction of external power and signals. Another part of the wire harness can be led to the electrical box inside the device through the inner cavity of the hollow cylinder of the inner support plate to provide power and signal connections for the electrical components inside the device. This design can ensure that each electrical component of the device obtains stable power support during operation. At the same time, the wire harness on the outer circle of the slip ring 8 can be led to the radiation source and detector ends through the bottom wire groove to connect relevant electrical components. In this way, through the design of the slip ring, not only can functions such as power-on and information transmission between external facilities and the CT device be realized, but also the reasonable layout and protection of the internal lines of the device can be ensured, avoiding potential problems caused by messy lines. Through this structural form of the inner support plate, with the slip ring as the medium, the organic combination of the electrical system of the CT device and external facilities is realized, ensuring the stability and reliability of the electrical connection of the entire system. This design not only improves the operation efficiency of the device, but also simplifies the installation and maintenance process of the device to a certain extent, avoiding cumbersome line layout and wiring operations, making the device more convenient and efficient in actual use. In addition, this design also fully considers the safety of the device. Through reasonable wire harness leading-out and layout, electrical short circuits or signal interference problems caused by messy cables are effectively avoided, further improving the operation stability and service life of the device. This carefully designed connection method and structural configuration ensure the reliability and safety of the CT device in various working environments, enabling it to stably and efficiently perform various imaging tasks in medical places and meet the high standards of clinical applications.
[0028] The bottom end of the flange 1 is provided with a base 16. The top end of the base 16 is fixedly installed with an outer support frame 15. The bottom end of the inner wall of the outer support frame 15 is connected to the bottom end of the flange 1. This design ensures the stability and durability of the entire structure, forming a firm connection between the flange and the base, thereby enhancing the overall stability of the equipment during operation. In a floor-standing dental CT system, the inner support plate is installed below the outer support frame 15 and above the base 16, and is used to support the relatively earth-stationary objects such as the outer support frame 15, the seat, and the electrical box above it and the patient. Thus, when performing dental imaging, a stable and comfortable sitting environment is provided for the patient, and the accuracy and reliability of the equipment during shooting are ensured. The design of the base 16 takes into account the overall load-bearing capacity of the equipment. It not only needs to support the weight of the equipment itself but also be able to bear the weight of the patient. Therefore, careful calculations are made in both material selection and structural design to ensure that its strength and stiffness meet the actual usage requirements. At the same time, the design of the outer support frame 15 also fully considers its cooperation with the inner support plate, enabling the center of gravity of the equipment to remain stable during the dynamic process, avoiding image blurring or equipment failure caused by the center of gravity deviation. The reasonable design of this overall structure not only improves the operation safety of the equipment but also enhances the patient's usage experience, making the entire dental CT system show higher efficiency and reliability in practical applications, providing more accurate imaging results for clinical use, and thus better serving the doctor's diagnosis and treatment work.
[0029] When the embodiment of this application is in use, the overall shape of the inner support plate is in the form of an inverted "umbrella". This design not only provides good load-bearing capacity but also effectively disperses the pressure from the upper structure, ensuring the stability and safety of the structure under load. There is a hollow cylinder in its center. The design of this hollow cylinder not only reduces the overall weight of the inner support plate but also provides sufficient space for the layout of internal circuits and electrical components, making the layout of the entire system neater and contributing to improving the aesthetics and functionality of the device. The holes near the top of the hollow cylinder are used for the passing of wire harnesses, allowing cables to be introduced from the outside to the internal electrical system. At the same time, this design does not affect the overall stability of the structure, ensuring the safety and reliability of the device during operation. In addition, a circular flange 1 is provided at the bottom. The design of the flange not only provides a stable support foundation but also makes electrical connection more flexible and convenient through the design of the openings. This opening design allows the wire harness to freely enter and exit, reducing the complexity of installation and maintenance. Although the shape of the flange is not limited to circular, the circular design can better disperse the load during stress and connection, ensuring that the material will not suffer fatigue or damage due to stress concentration during high-intensity use. Overall, through the structural design of this inner support plate, combining the inverted "umbrella" shape and the layout of the hollow cylinder, not only effectively improves the support capacity and stability but also optimizes the electrical connection and wire harness management of the device, thus enhancing the functionality and usability of the entire dental CT system.
[0030] A part of the wire harness with the inner ring outgoing line of the slip ring 8 can be led out of the device through the openings of the flange 1 at the bottom of the inner support plate and connected to the mains power, computer, etc. outside the CT device, ensuring a stable connection between the device and the external power supply. In addition, another part of the wire harness is guided through the inner cavity of the hollow cylinder of the inner support plate to the electrical box inside the device to provide the required power supply and signal connection for the internal electrical components. This design fully considers the reasonable layout and protection of the cables, avoiding potential risks caused by chaotic wiring. At the same time, the outer ring wire harness of the slip ring 8 is led to the X-ray source and detector ends through the bottom wire groove to connect relevant electrical components, realizing the effective connection between various parts of the CT device. Through this structural form of the inner support plate, with the slip ring as the medium, not only can the power-on and information transmission functions between external facilities and the CT device be realized, but also the orderly layout and protection of the internal wires of the device can be ensured, improving the overall efficiency and safety of the device.
[0031] A part of the wire harness with the inner ring of the slip ring 8 leading out can be led out of the device through the opening of the bottom flange 1 of the inner support plate, and connected to the mains power, computer, etc. outside the CT device, thus realizing the convenience of external power supply and information transmission. This design greatly simplifies the connection process between the device and the external power supply and signal source, avoids complex wiring, and makes the installation and maintenance of the device more efficient and convenient. Another part of the wire harness can be led to the electrical box inside the device through the inner cavity of the hollow cylinder of the inner support plate. This design not only ensures the integrity and functionality of the internal electrical system of the device, but also provides reliable power support for the device, ensuring the normal operation and efficient operation of electrical components. In addition, the wire harness on the outer ring of the slip ring 8 can be led to the X-ray source and detector ends through the bottom wire groove to connect relevant electrical components. This connection method effectively guarantees the stability and reliability between various electrical components, enables the entire CT system to perform imaging work smoothly during operation, reduces electrical faults or signal interference caused by messy wires, and improves the overall performance and service life of the device. Through such a design, the use of the slip ring gives full play to its advantages in electrical connection and signal transmission, realizes the efficient linkage between the CT device and external facilities, and provides strong support for clinical applications.
[0032] Generally speaking, through this structural form of the inner support plate, with the slip ring as the medium, functions such as power-on and information transmission between external facilities and the CT device can be realized, ensuring the efficiency and stability of the device during operation. This design not only simplifies the connection process between the device and the external power supply and signal source, but also ensures the reasonable layout of the cables, avoiding electrical short circuits or signal interference problems caused by messy wires. In addition, this design also fully considers the convenience of device maintenance, facilitating technicians to quickly access and check the internal electrical system of the device when needed, improving the usage efficiency and reliability of the device. Through quick access, technicians can conduct fault troubleshooting and maintenance more quickly, reducing downtime, and thus showing higher stability and safety in clinical applications. This comprehensive design concept makes the floor-standing dental CT system not only reach an excellent level in performance, but also make significant improvements in user experience and maintenance convenience, ensuring that medical workers can quickly and effectively perform dental imaging in a high-intensity working environment and provide better medical services.
