[0024] 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.

[0025] like Figure 1-4 As shown, the folding arm locking structure of the mobile DR includes a base 1 fixed on the frame, and also includes a locking slider 2 and a telescopic shaft 4. The telescopic shaft 4 is slidably connected to one side of the base 1, and the locking slider 2 is connected to one end of the telescopic shaft 4. Specifically: the locking slider 2 is connected to one end of the telescopic shaft 4 through a screw, and the locking slider 2 has a countersunk hole 1 that matches the screw to prevent the screw from protruding from the surface of the locking slider 2; the locking slider 2 has a guiding inclined surface 2a that matches the locking handle 7, and the locking slider 2 can abut against the other side of the base 1 to form a locking portion for locking the locking handle 7, and an elastic reset member is also installed between the locking slider 2 and the base 1.

[0026] The locking slide block 2 is provided with a limiting notch 2 b which matches with the locking handle 7 .

[0027] The other end of the telescopic shaft 4 is connected to the hand wheel 6.

[0028] An outer cover 5 is also installed on the base 1. The outer cover 5 not only has an aesthetic effect, but also plays a certain guiding role on the locking slider 2, so that the locking slider 2 can be more reliably stressed and ensure that when it is in the locked position, it does not only rely on the telescopic shaft 4 to bear the force, so that the locking slider 2 slides more smoothly.

[0029] The elastic reset member is a compression spring 3 .

[0030] The locking slide block 2 has a groove for positioning the compression spring 3 , and the position of the compression spring 3 can be fixed by the groove.

[0031] The base 1 has screw holes for fixing the outer cover 5 .

[0032] The base 1 has two countersunk holes for fixing it to the frame. In this embodiment, there are two countersunk holes.

[0033] The locking slider 2 is provided with a guiding inclined surface 2a. When working, the locking handle 7 only needs to be pressed vertically into the locking structure. Due to the force of the inclined surface, the locking slider 2 will move backwards. When the locking handle 7 is pressed into the limiting notch 2b in the locking slider 2, the locking slider 2 will rebound quickly under the action of the compression spring 3 to lock the locking handle 7. The locking handle 7 is installed on the folding arm. It is worth noting that the limiting notch 2b of the locking slider 2 should be slightly larger than the shape of the locking handle 7, so that the locking slider 2 can rebound smoothly, but it should not be too large to avoid large shaking of the locking handle 7 after locking. Usually, this gap is controlled between 1-2mm, and this gap can be selected according to actual needs. When releasing, pull the hand wheel 6 to retract the locking slider 2, and the locking handle 7 can be taken out.

[0034] In summary, the locking structure utilizes a simpler structure to realize the locking of the folding arm of the mobile DR; only two holes are required for installation, and a small space is occupied; the operation is convenient and reliable, and locking and releasing can be achieved by just pressing and pulling.

[0035] 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.

[0036] 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.
