Description

Technical Field

[0001] The utility model relates to the technical field of detectors, in particular to a handle assembly of a mobile DR filter grid detector. Background Art

[0002] The grid is used to filter out the influence of scattered rays on imaging. It should be placed between the human body and the detector. It can filter out most of the stray rays, reduce the gray fog, and improve the contrast. When the thickness and density of the object being photographed are relatively large, the grid can improve the imaging quality. When the object being photographed is relatively thin, there is no need to use the grid. When the object being photographed is relatively thick, the grid is required.

[0003] The grid detector assembly for mobile DR needs to be integrated into a handheld handle during use, so that doctors can perform diagnostic operations. However, the current mobile DR grid detector assembly is generally divided into a grid detector assembly and a non-grid detector assembly. For the non-grid detector assembly, when the object is thick, the image quality will be greatly affected because the stray scattered rays cannot be filtered out. The current grid detector assembly has the problem of complex grid removal operation, that is, it is impossible to freely switch between the grid and the non-grid. Therefore, in view of the above problems, a mobile DR grid detector handle assembly is proposed, which can effectively solve the above problems. Summary of the invention

[0004] The purpose of the present application is to provide a mobile DR grid detector handle assembly.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a mobile DR filter grid detector handle assembly, comprising a handle shell, characterized in that it also includes a locking card, the locking card is slidably connected to one end of the handle shell, and an elastic member is also installed between the locking card and the one end of the handle shell, the locking card has a locking protrusion, and the other end of the handle shell has a positioning protrusion, and under the joint action of the positioning protrusion and the locking protrusion, the filter grid and the detector can be detachably installed on the handle shell, and one end of the handle shell is also provided with a sliding locking buckle that can lock the locking card.

[0006] An L-shaped groove is provided at one end of the handle housing, a waist-shaped groove is provided on the locking card plate, the lower portion of the sliding locking buckle is slidably connected in the L-shaped groove, and the upper portion of the sliding locking buckle is slidably connected in the waist-shaped groove.

[0007] A magnet is also provided between the sliding locking buckle and the locking clamping plate.

[0008] One end of the L-shaped groove is an unlocking portion, the middle of the L-shaped groove is a locking portion, and the other end of the L-shaped groove is a locking retaining portion.

[0009] The number of the magnets is two, one of which is installed in the slot of the sliding locking buckle, and the other is installed in the slot of the locking card plate.

[0010] The elastic member is a spring, an elastic sheet or an elastic telescopic rod.

[0011] Both sides of the handle housing are also provided with limiting edges.

[0012] In summary, the technical effects and advantages of the utility model are:

[0013] 1. The filter grid can be easily installed and removed, which can adapt to more clinical diagnosis scenarios.

[0014] 2. It is more convenient to install and disassemble the filter grid and detector, and the fixation is more firm and reliable.

[0015] 3. It has fewer components and a small size, and can be well integrated into the handheld handle, making it very suitable for use in mobile DR. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] like Figure 1-Figure 5 As shown, the handle assembly of the mobile DR filter grid detector includes a handle shell 1 and a locking card plate 4. The locking card plate 4 is slidably connected to one end of the handle shell 1. An elastic member 7 is also installed between the locking card plate 4 and one end of the handle shell 1. The locking card plate 4 has a locking protrusion 4a, and the other end of the handle shell 1 has a positioning protrusion 1a. Under the joint action of the positioning protrusion 1a and the locking protrusion 4a, the filter grid 2 and the detector 3 can be detachably installed on the handle shell 1. One end of the handle shell 1 is also provided with a sliding locking buckle 5 that can lock the locking card plate 4.

[0025] An L-shaped groove 1c is provided at one end of the handle housing 1, a waist-shaped groove 4b is provided on the locking card 4, the lower part of the sliding locking buckle 5 is slidably connected in the L-shaped groove 1c, and the upper part of the sliding locking buckle 5 is slidably connected in the waist-shaped groove 4b. Specifically: one end of the L-shaped groove 1c is an unlocking part, the middle part of the L-shaped groove 1c is a locking part, and the other end of the L-shaped groove 1c is a locking retaining part.

[0026] There is also a magnet 6 between the sliding locking buckle 5 and the locking card plate 4. Specifically, there are two magnets 6, one of which is installed in the slot of the sliding locking buckle 5, and the other magnet 6 is installed in the slot of the locking card plate 4.

[0027] The elastic member 7 is a spring, an elastic sheet or an elastic telescopic rod. In this embodiment, the elastic member 7 is a spring, and the number of the springs is two.

[0028] Both sides of the handle housing 1 are also provided with limiting edges 1b, which can prevent the grid 2 and the detector 3 from sliding out from the side of the handle.

[0029] When in use, when it is necessary to install the filter grid 2, it is necessary to manually move the sliding locking buckle 5 toward one end of the L-shaped groove 1c of the handle shell 1, and the sliding locking buckle 5 drives the locking card plate 4 to move backward together. At this time, the elastic member 7 is in a compressed state, and the filter grid detector handle assembly is in an open state; the filter grid 2 and the detector 3 are placed in the handle shell 1 in sequence, so that one end of them is inserted into the positioning protrusion 1a, and then the sliding locking buckle 5 is released, and the elastic member 7 recovers its deformation. At this time, the sliding locking buckle 5 is released to drive the locking card plate 4 to move to the middle of the L-shaped groove 1c of the handle shell 1. At this time, the sliding locking buckle 5 is continued to be pushed to move toward the other end of the L-shaped groove 1c until the magnet 6 in the sliding locking buckle 5 is in an attracted state with the magnet 6 in the locking card plate 4. At this time, the filter grid 2 and the detector 3 are in a fixed locked state; when it is not necessary to install the filter grid 2, the filter grid 2 is taken out, and the rest of the operations are the same as above.

[0030] The above components are all common standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
