Description

Technical Field

[0001] This application relates to the field of X-ray grid fixing devices, and more particularly to an X-ray grid fixing and indicating handle device. Background Technology

[0002] X-ray grids are specialized equipment components used in X-ray imaging. Their main function is to filter out stray rays and improve image quality. X-ray grid fixing devices are used to install the grids on X-ray imaging equipment to ensure that the grids do not move or deform during use, making the grids filter rays more efficiently and making X-ray images clearer. In addition, different grids may be needed or the grids may need to be removed due to different SIDs or the needs of children.

[0003] For example, patent application number 202322606972.2 discloses a filter grid fixing device, but it still has the following shortcomings in actual use:

[0004] The device consists of a frame, a hinged locking element, and a filter grid assembly. It is fixed by engaging the locking element with the toothed groove on the side of the fixing plate. When disassembling, press the locking element to unlock it and pull the assembly directly out along the guide groove. During use, it is necessary to press the locking element and pull out the fixing plate at the same time. In an emergency, it is difficult to operate quickly with one hand, which is inefficient and inconvenient to replace filter grids of different specifications. Utility Model Content

[0005] To address the issues of difficulty in quickly replacing X-ray grid fixing devices and their adaptability to different specifications, this application provides an X-ray grid fixing and indicating handle device.

[0006] The X-ray filter grid fixing and indicating handle device provided in this application adopts the following technical solution:

[0007] An X-ray filter grid fixing and indicating handle device includes a filter grid frame and a slide rail fixed inside the filter grid frame. An adjustment mechanism is slidably arranged on the inner side of the slide rail, and a locking mechanism for locking the adjustment mechanism is fixed at one end of the inner side of the slide rail. The adjustment mechanism includes a fixed plate, a bidirectional screw is rotatably arranged inside one end of the fixed plate, an adjustment shaft is fixedly sleeved on the outer side of the middle part of the bidirectional screw, and clamping blocks are threaded on both ends of the bidirectional screw. A bidirectional screw is rotatably arranged inside the fixed plate at the end adjacent to the bidirectional screw, and clamping blocks are threaded on both ends of the bidirectional screw.

[0008] By adopting the above technical solution, the device enables the rapid insertion of the filter grid through the slide rail and adjustment mechanism. The bidirectional screw drives the clamping block to move and fix filter grids of different sizes, which improves the adaptability of the device to filter grids of different specifications. The locking mechanism locks the adjustment mechanism, which improves the stability of the structure.

[0009] Preferably, the end of the bidirectional screw one near the bidirectional screw two is fixed with a bevel tooth one, and the end of the bidirectional screw two near the bidirectional screw one is fixed with a bevel tooth two that meshes with the bevel tooth one.

[0010] By adopting the above technical solution, the meshing of bevel gear one and bevel gear two causes bidirectional screw one and bidirectional screw two to rotate in tandem, thereby achieving synchronous adjustment of clamping block one and clamping block two.

[0011] Preferably, the two clamping blocks 2 are provided with limiting grooves at both ends for the two clamping blocks 1 to slide inside the clamping blocks 2.

[0012] By adopting the above technical solution, the design of the limiting groove allows the first clamping block to slide inside the second clamping block, enhancing the flexibility of the adjustment mechanism.

[0013] Preferably, locking blocks are fixed at both ends of the fixed plate on the side away from the adjusting shaft.

[0014] By adopting the above technical solution, the locking block facilitates the subsequent fixing of the adjustment mechanism.

[0015] Preferably, the locking mechanism includes a rotating shaft, a second locking clip is movably sleeved in the middle of the rotating shaft, and a first locking clip is movably sleeved at both ends of the rotating shaft located outside the second locking clip.

[0016] By adopting the above technical solution, the locking mechanism connects locking clamp one and locking clamp two through a rotating shaft, which facilitates the fixing of the adjusting mechanism.

[0017] Preferably, a fixing block is fixed on the opposite side of both locking clamp one and locking clamp two, and a compression spring is fixed on the bottom end of both fixing blocks near the slide rail.

[0018] By adopting the above technical solution, the design of the fixing block and compression spring provides the locking mechanism with the power to reset after being squeezed, which facilitates the quick insertion or disengagement of the locking block into or out of the locking mechanism.

[0019] Preferably, a fixed post is movably provided on the back of the filter grid frame, and a fixed seat that slides on the fixed post is fixedly provided on the side of the filter grid frame near the fixed post. A handle is rotatably provided inside the fixed seat.

[0020] By adopting the above technical solution, the filter grid frame slides and is fixed on the fixed column through the fixed seat and the handle, which makes it easy to adjust the height of the device as needed.

[0021] An indicator handle, applied to the aforementioned X-ray filter grid fixing device, includes a handle fixed to one side of a fixing plate.

[0022] By adopting the above technical solution, a handle is used to lift and adjust the device, which facilitates the quick installation and replacement of the adjustment device.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By rotating the adjusting shaft, the bidirectional screw one and bidirectional screw two are driven to rotate, which in turn drives the two clamping blocks one and two clamping blocks two to move in opposite or relative directions, thereby realizing bidirectional synchronous and precise adjustment of the filter grid, which facilitates the quick installation, disassembly or replacement of the filter grid and improves the adaptability of the device to filter grids of different specifications.

[0025] 2. This device, through the cooperation of the locking mechanism and the locking block, enables the locking block to automatically lock the moment it is inserted into the locking mechanism and quickly unlock when it is pulled out. The operation is simple and quick. In an emergency, the user can quickly replace the filter grid with one hand, which improves work efficiency and brings users a more convenient and efficient user experience.

[0037] The following is in conjunction with the appendix Figure 1 - Figure 7 This application will be described in further detail.

[0038] This application discloses an X-ray filter grid fixing and indicating handle device.

[0039] Reference Figure 1 - Figure 2 An X-ray filter grid fixing and indicating handle device includes a filter grid frame 1 and a slide rail 7 fixed inside the filter grid frame 1. An adjustment mechanism 2 is slidably arranged on the inner side of the slide rail 7, and the inner side of the slide rail 7 provides a sliding path for the adjustment mechanism 2. Both the slide rail 7 and the adjustment mechanism 2 are made of plastic materials such as nylon that are not easily deformed. The adjustment mechanism 2 is used to adapt to filter grids of different specifications and materials, such as wood chips, plastic and other hard non-metallic low-density materials. A fixing post 4 is movably arranged on the back of the filter grid frame 1. A fixing seat 9 is fixed on the side of the filter grid frame 1 near the fixing post 4. A sliding rail is provided on the side of the fixing post 4 facing the filter grid frame 1. The fixing seat 9 slides in the sliding rail. A handle 5 is rotatably arranged inside the fixing seat 9. The handle 5 is used to lock the filter grid frame 1 when it slides longitudinally. The filter grid frame 1 can be unlocked when the handle 5 is flipped downward.

[0040] Before use, the device is fixed by fixing the filter grid frame 1 to the fixed base 9, and the fixed base 9 is installed on the sliding rail reserved on one side of the fixed column 4. By flipping the handle 5 downward to the unlock position, the lock on the filter grid frame 1 is released, allowing the filter grid frame 1 to move freely on the sliding rail of the fixed column 4. The slide rail 7 is embedded inside the filter grid frame 1, and the locking mechanism 8 is fixed inside the slide rail 7. The locking mechanism 8 is in the ready-to-trigger state.

[0041] Reference Figure 3 - Figure 5The adjusting mechanism 2 includes a fixed plate 201. A bidirectional screw 207 is rotatably mounted inside one side of the fixed plate 201. Rectangular slots 203 are formed at the upper and lower ends of the fixed plate 201 where the bidirectional screw 207 is located. An adjusting shaft 204 is fixedly sleeved on the outer side of the middle part of the bidirectional screw 207. The adjusting shaft 204 is located at the rectangular slot 203, which exposes the upper and lower sides of the adjusting shaft 204 to the air. The adjusting shaft 204 is rotated through the rectangular slot 203. Adjusting slots 22 are symmetrically formed at both ends of the fixed plate 201. 13. Both ends of the bidirectional screw 207 are threaded with clamping blocks 206. The two ends of the clamping blocks 206 slide through the four adjusting slots 213. The fixed plate 201 is rotatably provided with a bidirectional screw 210 on the side adjacent to the bidirectional screw 207. The two ends of the inner walls of the fixed plate 201 and the rectangular slot 203 are symmetrically provided with adjusting slots 212. Both ends of the bidirectional screw 210 are threaded with clamping blocks 205. The two ends of the clamping blocks 205 slide through the four adjusting slots 212.

[0042] When installing the filter grid, place the filter grid between two clamping blocks 205 and two clamping blocks 206. By rotating the adjusting shaft 204, drive the bidirectional screw 207 to rotate the bevel gear 208. Since the bevel gear 208 meshes with the bevel gear 209 at the top of the bidirectional screw 210, the bidirectional screw 210 rotates, causing the clamping blocks 206 to move in opposite directions at both ends of the bidirectional screw 207. At the same time, the clamping blocks 206 move in opposite directions at both ends of the bidirectional screw 210, thereby fixing the filter grid in the middle of the adjusting mechanism 2.

[0043] A bevel tooth 208 is fixed at one end of the bidirectional screw 207 near the bidirectional screw 210, and a bevel tooth 209 is fixed at one end of the bidirectional screw 210 near the bidirectional screw 207. The teeth on the surface of the bevel tooth 208 mesh with the teeth on the surface of the bevel tooth 209. Limiting grooves 211 are symmetrically opened at both ends of the two clamping blocks 206, and the two clamping blocks 205 move through the interior of the two pairs of limiting grooves 211.

[0044] Reverse rotation of the adjusting shaft 204 causes the bidirectional screw 207 to drive the two clamping blocks 205 to move in opposite directions, while simultaneously causing the bidirectional screw 210 to drive the clamping block 206 to move in opposite directions. At this time, the filter grid can be removed from the adjusting mechanism 2.

[0045] Locking blocks 202 are fixed on both ends of the fixed plate 201 away from the adjusting shaft 204. The locking block 202 is composed of a plastic sphere and a plastic wedge. The locking block 202 is used to be inserted into the locking mechanism 8 simultaneously when the adjusting mechanism 2 is inserted into the filter wire grid 1 to lock the filter wire grid 1. The inner wall of the slide rail 7 is provided with locking grooves 10 symmetrically on both ends of the side near the locking block 202. The locking mechanism 8 is fixed in the interior of the two locking grooves 10 respectively.

[0046] In use, the locking block 202 is inserted into the locking mechanism 8 by inserting the adjusting mechanism 2 into the center of the slide rail 7 along the inner wall of the two guide plates 6 on opposite sides.

[0047] Reference Figure 6 , Figure 7 The locking mechanism 8 includes a rotating shaft 801. All parts of the locking mechanism 8 are made of plastic materials such as nylon. The two ends of the rotating shaft 801 are fixed to the inner top surface and the inner bottom surface of the locking groove 10, respectively. A second locking clamp 803 is movably sleeved in the middle of the rotating shaft 801. The second locking clamp 803 is a semi-circular plastic gripper. Locking clamps 802 are movably sleeved at both ends of the rotating shaft 801. The lower ends of the first locking clamp 802 are located on both sides of the second locking clamp 803. The first locking clamp 802 is formed by splicing two second locking clamps 803. When the first locking clamp 802 and the second locking clamp 803 approach each other, they combine to form a gripper for holding the locking block 202. Fixing blocks 804 are fixed on the opposite side of the second locking clamp 803 and the first locking clamp 802. The two fixing blocks 804 are close to the lock... Compression springs 805 are fixed on one side of the inner bottom surface of the stop groove 10. The formula for calculating the spring force of the compression spring is F = kx, where F represents the spring force, k represents the spring constant (the magnitude of the spring force generated by the spring under force per unit length), and x represents the spring compression (the displacement distance of the spring from its original state to its compressed state). The spring force of the compression spring 805 can be calculated using this formula. The two ends of the compression spring 805 are fixed to the fixing block 804 and the inner bottom surface of the locking groove 10, respectively. A sliding groove is provided on the inner side of the slide rail 7. The sliding groove allows the fixing plate 201 to slide quickly inside the slide rail 7. Guide plates 6 are symmetrically fixed on both ends of the slide rail 7 near the adjusting shaft 204. The guide plates 6 are used to guide the fixing plate 201 when it is inserted into the filter grid frame 1.

[0048] Due to the compression of locking clip 1 802 and locking clip 2 803 by locking block 202, locking clip 1 802 and locking clip 2 803 rotate in opposite directions around the rotation shaft 801. At this time, the two compression springs 805 are compressed. When the surface of locking block 202 is in contact with the inner wall of locking clip 1 802 and locking clip 2 803, the compression springs 805 rebound and drive locking clip 1 802 and locking clip 2 803 to rotate in opposite directions, thereby fixing locking block 202 in locking clip 1 802 and locking clip 2 803, and locking adjustment mechanism 2 in slide rail 7. When it is necessary to unlock adjustment mechanism 2, pull adjustment mechanism 2 outward to make locking clip 1 802 and locking clip 2 803 rotate in opposite directions again, and at the same time, locking block 202 is released from the restriction of locking clip 1 802 and locking clip 2 803.

[0049] The implementation principle of the X-ray filter grid fixing and indicating handle device in this application embodiment is as follows: The filter grid is placed between two clamping blocks 205 and two clamping blocks 206. By rotating the adjusting shaft 204, the fixing plate 201 and the bidirectional screw 210 are rotated, causing the two clamping blocks 205 and 206 to move in opposite or opposite directions, thereby fixing and releasing the filter grid. In use, the adjusting mechanism 2 is inserted into the slide rail 7 along the guide plate 6, and at the same time, the locking block 202 is inserted into the locking clamp 802 and the locking clamp 803, so that the locking block 202 is locked in the locking mechanism 8. Pulling the adjusting mechanism 2 outward causes the locking block 202 to be released from the restriction of the locking mechanism 8, thereby unlocking the adjusting mechanism 2.

[0050] An indicator handle is applied to the aforementioned X-ray filter grid fixing device, including a handle 3 fixed to one side of the fixing plate 201. The handle 3 is used to lift the entire adjustment mechanism 2, so that the adjustment mechanism 2 can be inserted into the filter grid frame 1.

[0051] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
