After the polytetrafluoroethylene cloth is wrapped, the edge fit is poor and the edge coverage is not neat. Furthermore, after the copper plate is covered, it is easy for the copper plate to misalign due to gravity. Summary of the Invention

[0004] In view of this, the present invention provides a coil device for nuclear magnetic resonance tomography to solve the problem that, when using existing coil devices, local loosening and detachment of copper wires are prone to occur.

[0005] This invention provides a coil device for nuclear magnetic resonance tomography, specifically comprising: a main body; the main body is the coil device body, made of epoxy resin fiberglass, and has a cylindrical tubular structure. The outer side of the main body has evenly arranged embedding grooves, and auxiliary components are installed inside the embedding grooves. These auxiliary components have a U-shaped structure and are made of elastic plastic. The inner and outer ends of the auxiliary components are inclined. Each auxiliary component has two contact elements on its inner sides, each contact element having an arc-shaped structure and being made of rubber. Side components, each side component having a ring-shaped structure, are provided in pairs. Located on both sides of the main body, each side component has a ring-shaped slot on its inner side. Each slot contains an L-shaped insert plate made of elastic plastic. Each insert plate has a rectangular pressure block made of rubber on its inner side. The mounting components are rectangular in structure, and there are four mounting components in total. These four mounting components are installed at the upper and lower ends of the main body. Between every two mounting components are two pressure rods, and between every two pressure rods are evenly arranged inner plates. Each inner plate has a contact plate at its bottom, which is an H-shaped plate made of rubber.

[0006] Optionally, the embedding groove is an annular structure with a rectangular cross-section. Each embedding groove has an auxiliary groove on each of its two inner sides. The auxiliary groove is also an annular structure with a cylindrical cross-section. The main body has two pressing grooves on its upper and lower sides. The pressing grooves are rectangular and communicate with the interior of the embedding groove. Each pair of pressing grooves has a locking slot at each end. The locking slot is rectangular. Each locking slot has a locking block on its inner side. The locking block is wedge-shaped. Each auxiliary component has an inner component on each of its two inner sides. The inner component is arc-shaped with a cylindrical cross-section and is made of rubber. Each inner component has a V-shaped groove on its outer side and is embedded in the interior of the auxiliary groove.

[0007] Optionally, the slot is a rectangular structure, and each side piece has a limiting groove at its upper and lower inner ends. The limiting groove is rectangular.

Each inner plate has a force-bearing groove with a rectangular structure on its inner side. A contact plate is embedded inside the force-bearing groove. Each contact plate has a connecting block with an L-shaped structure at its corner, and the connecting block contacts the side of the inner plate at the included angle.

[0009] Beneficial effects

[0010] 1. By setting auxiliary components and contact components, this device allows the auxiliary components to be easily embedded into the embedding groove during use, so that the interior of the auxiliary components can come into contact with the epoxy resin. At the same time, when assembling copper wires, the copper wires can be controlled to be embedded into the interior of the auxiliary components, so that the sides of the copper wires can come into contact with the contact components, allowing the contact components to be squeezed. The auxiliary components can be freely adjusted in installation position according to usage requirements. After installation, they can automatically clamp the copper wires under force, so that the copper wires can be fixed and prevent the copper wires from becoming loose in some areas.

[0011] 2. By setting up the mounting component, when the copper wire is embedded in the embedding groove, the installation of the mounting component can be controlled so that the top of the mounting component can contact the locking block, and the pressure rod can be driven to install and use together. The pressure rod can be positioned on the side of the copper wire connection, thereby initially positioning and fixing the copper wire. At the same time, the contact rod uses its own elasticity to continuously press the copper wire connection position, thereby preventing slippage and fixing, improving the connection effect, and preventing the copper wire from loosening.

[0012] 3. By setting up a movable component, after the copper wire is embedded and epoxy resin is applied during use, the installation of the copper plate can be controlled, allowing the copper plate to contact the contact block and contact rod. At the same time, the plastic spring continuously pushes the movable component to move, so that the movable component is continuously subjected to force and moves, so that the contact rod is fixedly contacted and limited with the copper plate. At the same time, the contact block can be used to prevent the copper plate from slipping and limiting the contact. After the copper plate contacts the epoxy resin, the connection and fixation effect can be improved, and the copper plate can be prevented from moving and misaligning due to gravity.

[0013] 4. By setting up the insert plate, when the copper plate is covered, the device can control the coverage of the PTFE cloth. After the copper plate is covered, the PTFE cloth can be evenly covered. After the cloth is covered, the insert plate can be manually controlled to insert into the slot, thereby driving the pressure block to be installed. The insert plate and the pressure block use their own elasticity to continuously push the PTFE cloth, so that the edges of the PTFE cloth can be pressed neatly, and the adhesion effect of the PTFE cloth can be improved.
