Technical Field

[0001] The utility model belongs to the technical field of imaging plate fixing, and in particular relates to a DR imaging plate fixing device. Background Art

[0002] X-ray digital imaging systems generally include X-ray sources, imaging boards, data acquisition, transmission processing units, computer image software processing, data storage and image display, etc. The imaging board is made of special materials and mainly consists of a scintillator layer, an amorphous silicon layer, a thin film transistor array and a readout circuit. The board thickness varies from 20mm to 40mm, and the imaging area is about 1000cm 2 The imaging plate is relatively heavy. In a complex working environment, it is difficult to achieve the expected effect and the quality is difficult to meet the requirements. Therefore, solid measures are needed to ensure the reception of X-rays.

[0003] At present, the three-dimensional controllable movable platform of the imaging plate detector of the X-ray scatterer and the light scatterer with the announcement number CN102628791B on the market includes a base, a dovetail groove slide, a lifting platform, a translation platform, a right-angle block and an imaging plate holder; the dovetail groove slide is arranged on the upper part of the base, the base is provided with a dovetail boss, the dovetail boss is provided with a scale, and the dovetail boss is slidably matched with the dovetail groove of the dovetail groove slide; the top of the dovetail groove slide is fixedly connected to the lifting platform; the top of the lifting platform is fixedly connected to the translation platform; the right-angle block is fixedly arranged on the table of the translation platform, and the side wall of the right-angle block is fixedly connected to the imaging plate holder. This invention is an accessory of a small-angle X-ray scatterer or a light scatterer, and its structure is compact and reasonable, and the loading and unloading of the imaging plate is convenient and quick, and it is easy to calibrate, so that the distance between the imaging plate and the fixed sample is precisely adjustable, so that it can be precisely adjusted for different measurement ranges of the sample to obtain the required data and improve the analysis accuracy.

[0004] But there is also a problem: the imaging plate of the device is exposed to the air and easily accumulates dust, resulting in poor imaging effects. Utility Model Content

[0005] The present invention provides a DR imaging plate fixing device, which is used to solve the problem that dust is easily adhered to the imaging plate.

[0006] The present invention provides a DR imaging plate fixing device, comprising a base; a lifting platform: the lifting platform is fixedly connected to the base, and the lifting platform is used to control the movement of the imaging plate; the imaging plate: the imaging plate cooperates with the lifting platform; a protective shell: the protective shell wraps the imaging plate, and the protective shell is provided with a detachable cover, the cover cooperates with the imaging plate, and the cover is a cover made of X-ray transparent material.

[0007] The principle of this solution is that the operator removes the cover plate, which is made of plastic, and then places the imaging plate in the protective shell so that the imaging plate and the cover plate are parallel, and then installs the cover plate to complete the installation. When the imaging plate needs to be moved, it only needs to start the lifting platform, and the lifting platform drives the protective shell to move to the set position.

[0008] The beneficial effect of this solution is that: this solution protects and isolates the imaging plate through the protective shell, preventing dust in the air from adhering to the imaging plate and affecting the imaging effect.

[0009] Furthermore, the protective shell is provided with a heat sink, which is located behind the imaging board and helps the imaging board to dissipate heat through heat dissipation holes, thereby preventing the imaging board from overheating and causing a short circuit.

[0010] Furthermore, it also includes an air circulation mechanism, which includes a cylinder and a blocking plate, and the cylinder includes a cylinder body, a spring, a piston and a push rod. The cylinder body is fixedly connected to a protective shell, and the cylinder body is provided with an air inlet and an air outlet. The air inlet and the air outlet are both provided with a one-way valve, and the air outlet is communicated with the protective shell. The piston is sealingly and slidably connected to the inside of the cylinder body, the blocking plate is fixedly connected to the top of the lifting platform, one end of the push rod is fixedly connected to the piston, and the other end cooperates with the blocking plate, and one end of the spring is fixedly connected to the cylinder body, and the other end is fixedly connected to the piston.

[0011] When the device completes one imaging, the operator can control the lifting platform to start, so that the protective shell moves up to the top as a whole. The upward movement of the protective shell will drive the cylinder to move up, and the upward movement of the cylinder will drive the push rod to move up. The push rod will touch the top blocking plate, causing the push rod to move down, and the push rod will move down. The piston will move down, causing the cylinder outlet to spray into the protective shell, speeding up the internal air flow, dissipating the heat, keeping the internal temperature normal, and preparing for the next imaging. When imaging is needed, the protective shell will move down again, and the push rod will reset under the action of the spring to ensure the next exhaust.

[0012] Furthermore, it also includes a cleaning mechanism, which includes a cleaning plate and a cleaning ball. The protective shell is provided with a cleaning port. One end of the cleaning plate is fixedly connected to the top rod, and the other end is slidably connected to the cleaning port. The cleaning ball is fixedly connected to the cleaning plate, and the cleaning ball cooperates with the imaging plate.

[0013] Due to the existence of the heat sink, some dust will still enter through the heat dissipation holes and adhere to the imaging plate, and wiping the imaging plate requires removing the cover plate, which is very troublesome. In this solution, when the imaging plate is completed, the operator can control the lifting platform to start, so that the protective shell moves up to the top as a whole. The upward movement of the protective shell will drive the cylinder to move up, and the upward movement of the cylinder will drive the push rod to move up. The push rod will touch the blocking plate, causing the push rod to move down relative to the cylinder body. At the same time, the cleaning plate will also move down, and the cleaning ball will also move down, and the cleaning ball will wipe the surface of the imaging plate. This mechanism can wipe the imaging plate after each imaging is completed to prevent dust from adhering to the imaging plate.

[0014] Furthermore, it also includes a fixing frame, which is fixed inside the protective shell by bolts, and the imaging plate is detachably fixedly connected to the fixing frame by bolts.

[0015] The fixing bracket can fix the imaging plate in the protective shell to prevent the imaging plate from shaking. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] This solution provides a DR imaging plate fixing device, including a base 1, the base 1 is an existing anti-slip base 1, the lifting platform 2 is an existing medical electric lifting platform 2, the lifting platform 2 is fixed on the base 1, and a blocking plate 3 is horizontally fixed at the bottom of the lifting platform 2. The lifting device of the lifting platform 2 is fixedly connected to the protective shell 8 through a connecting column 9, and the protective shell 8 is driven to rise and fall through the connecting column 9. The protective shell 8 is made of a light and thin material as a whole, a cleaning port is provided on the top of the protective shell 8, and a heat dissipation plate 13 is provided at the lower left side of the protective shell 8.

[0022] Two cylinders 15 are provided, symmetrically arranged on both sides with the protective shell 8 as the center. The cylinder 15 includes a cylinder body, a piston 11 and a push rod 4. The cylinder body is fixedly connected to the protective shell 8. The cylinder body is provided with an air inlet and an air outlet. The air inlet and the air outlet are both provided with a one-way valve. The air outlet is connected to the protective shell 8. The piston 11 is sealed and slidably connected to the inside of the cylinder body. The blocking plate 3 is fixedly connected to the top of the lifting platform 2. One end of the push rod 4 is fixedly connected to the piston 11, and the other end is located below the blocking plate 3. One end of the spring 10 is fixedly connected to the cylinder body, and the other end is fixedly connected to the piston 11.

[0023] As attached Figure 1 , Figure 3 As shown:

[0024] It also includes a cleaning mechanism, which includes a cleaning plate 5 and a cleaning ball 7. The protective shell 8 is provided with a cleaning port. One end of the cleaning plate 5 is fixedly connected to the top rod 4, and the other end is slidably connected to the cleaning port. The cleaning ball 7 is fixedly connected to the cleaning plate 5. The cleaning ball 7 is located at the front end of the imaging plate 12. When the top rod 4 does not touch the blocking plate 3, the cleaning ball 7 is located above the imaging plate 12 and will not block the imaging plate 12. The working range of the imaging plate 12 is also within the area not touched by the top rod 4. The imaging plate 12 is fixed to the fixing frame 14 by bolts, and the fixing frame 14 is fixed to the inside of the protective shell 8 by bolts. The fixing frame 14 can fix the imaging plate 12 in the protective shell 8 to prevent the imaging plate 12 from shaking.

[0025] As attached Figure 1 , Figure 2 , Figure 3 As shown:

[0026] The principle of this solution is that the operator removes the cover plate 6, which is made of plastic, and then places the imaging plate 12 on the fixing frame 14 in the protective shell 8, and then fixes it with bolts so that the imaging plate 12 is parallel to the cover plate 6, and then installs the cover plate 6 to complete the installation. When the imaging plate 12 needs to be moved, it only needs to start the lifting platform 2, and the lifting platform 2 drives the protective shell 8 to move to the set position.

[0027] When the device completes one imaging, the operator can control the lifting platform 2 to start, so that the protective shell 8 moves up to the top as a whole. The upward movement of the protective shell 8 will drive the cylinder 15 to move up, and the upward movement of the cylinder 15 will drive the push rod 4 to move up. The upward movement of the push rod 4 will touch the top blocking plate 3, causing the push rod 4 to move down. The downward movement of the push rod 4 will cause the piston 11 to move down, causing the air outlet of the cylinder 15 to spray into the protective shell 8, speeding up the internal air flow, dissipating the heat, and maintaining the internal temperature normal, ready for the next imaging. At the same time, the cleaning plate 5 also moves down, and the cleaning ball 7 also moves down, and the cleaning ball 7 will wipe the surface of the imaging plate 12. This mechanism can wipe the imaging plate 12 after each imaging is completed to prevent dust from adhering to the imaging plate 12.

[0028] When imaging is required, the protective shell 8 will move down again, and the ejector rod 4 and the cleaning ball 7 will be reset under the action of the spring 10 to ensure the next exhaust.

[0029] The beneficial effects of this solution are: 1. This solution protects and isolates the imaging plate 12 through the protective shell 8 to prevent dust in the air from adhering to the imaging plate 12 and affecting the imaging effect. 2. The airflow circulation mechanism improves the heat dissipation problem inside the protective shell 8 to prevent the imaging plate 12 from overheating.
