Description

Technical Field

[0001] The utility model relates to the technical field of DR equipment, in particular to an anti-falling structure of a foldable mobile DR equipment. Background Art

[0002] As is known to all, DR equipment is an advanced X-ray machine formed by combining computer digital image processing technology with X-ray radiation technology. On the basis of direct film imaging of the original diagnostic X-ray machine, a flat-panel detector is fixed on a vertical chest stand or a photographic flat bed. During exposure, the X-ray image information received by the flat-panel detector is directly transmitted. Therefore, DR equipment is widely used in the medical field.

[0003] Through A / D and D / A conversion, the computer system performs real-time digital image processing without the need for a dark box, thereby making the image digitized. Medical drx breaks the concept of traditional X-ray machines and realizes the long-desired transformation from analog X-ray images to digital X-ray images.

[0004] The portable DR device is easy to move via rollers and can be used in various scenarios. The head and frame of the DR device are usually installed through threaded connections. However, during long-term use, the vibration generated when the DR moves will cause the threads used to connect the head and frame to gradually loosen, causing the head and frame to fall, which brings certain shortcomings to the DR device.

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] See also Figure 1-3 The anti-fall structure of the foldable mobile DR equipment is used to solve the problem that the convenient DR equipment is easy to move through rollers and can be applied to various scenarios. The head and frame of the DR equipment are usually installed by threaded connection. During long-term use, the vibration generated when the DR moves will cause the threads used to connect the head and the frame to gradually loosen, causing the head and the frame to fall, which brings certain problems to the DR equipment.

[0023] As a further technical solution proposed by the present invention, the frame 1 and the head 3 are included, and further include: a frame 2, which is arranged on the frame 1; a bracket 3.1, which is connected to the head 3 and is located on the frame 2, a first connecting member 3.2 is rotatably arranged on the bracket 3.1, the first connecting member 3.2 is connected to the second connecting member 3.4 through an elastic reset member 3.3, and a clamping rod 3.5 is relatively arranged on the second connecting member 3.4; a clamping block 2.2 is arranged on the frame 2 to be clamped and matched with each clamping rod 3.5. Specifically, when the frame 1 and the head 3 are installed, as shown in FIG. Figure 2 and Figure 3 As shown in the state, the bracket 3.1 on the machine head 3 is first placed in the frame 2, and then the second connecting piece 3.4 is rotated down to engage with the clamping block 2.2 on the frame 2. At this time, the machine head 3 is fixedly installed on the frame 2 of the rack 1 through the bracket 3.1, which is easy to operate. The device installs the rack 1 and the machine head 3 by a clamping connection, which weakens or even avoids the vibration generated when the DR moves during long-term use, which will cause the threaded parts used to connect the machine head and the rack to gradually loosen, causing the machine head and the rack to fall.

[0024] In this embodiment, the first connecting member 3.2 is slidably connected to the second connecting member 3.4, and an elastic return member 3.3 is provided between the two. The elastic return member 3.3 is specifically a spring, which improves the stability of the clamping rod 3.5 and the clamping block 2.2 when they are clamped together. It should be noted that when the clamping rod 3.5 and the clamping block 2.2 are clamped together, the spring is in a stretched state, thereby increasing the strength of the clamping connection between the two and improving the stability.

[0025] In another embodiment of the utility model, preferably, a protrusion 2.1 is provided on the frame 2, and a concave space is formed between the protrusion 2.1 and the frame 2, and the card holder 3.1 is located in the concave space. Figure 2 As shown in the state, the protrusion 2.1 is specifically a rectangular structure. After it is connected to the frame 2, the two form a concave space. During installation, the head 3 is placed in the concave space through the bracket 3.1. The stability of the head 3 after installation is improved through the limitation of the concave space.

[0026] In another embodiment of the utility model, each clamping block 2.2 is provided with a wedge-shaped portion 2.3, and each wedge-shaped portion 2.3 is wedge-matched with each clamping rod 3.5, such as Figure 3 As shown in the state, during the process of the second connecting member 3.4 rotating and descending to cooperate with the clamping block 2.2, it will first cooperate with the wedge-shaped portion 2.3 in a wedge shape, so that the second connecting member 3.4 and the first connecting member 3.2 move away from each other (that is, the second connecting member 3.4 slides on the former), and at the same time the elastic reset member 3.3 is stretched, thereby improving the strength of the clamping rod 3.5 and the clamping block 2.2 after being clamped by the elastic reset member 3.3, as shown in FIG. Figure 2 Status shown.

[0027] In another embodiment of the utility model, preferably, a slide groove is provided on the second connecting member 3.4, and the first connecting member 3.2 is slidably engaged with the slide groove through a convex rod. The slide groove enables the second connecting member 3.4 to slide on the first connecting member 3.2 when the second connecting member 3.4 is wedge-fitted with the wedge-shaped portion 2.3 through the clamping rod 3.5, that is, adaptive adjustment is performed, so that the elastic reset member 3.3 can be stretched.

[0028] In another embodiment of the utility model, preferably, each clamping block 2.2 is further provided with a limiting portion 2.4, each limiting portion 2.4 is specifically an arc-shaped structure, each clamping rod 3.5 is engaged with each limiting portion 2.4, and further, during the subsequent rotation and descent process of the clamping rod 3.5 and the wedge-shaped portion 2.3 wedge-shaped cooperation stretching the elastic reset member 3.3, the clamping rod 3.5 will be stuck in the limiting portion 2.4, such as Figure 2 As shown in the state, the mounting of the frame 1 and the machine head 3 is completed by the engagement of the clamping rod 3.5 with the clamping block 2.2 and the clamping frame 3.1 being located in the frame 2.

[0029] In another embodiment of the utility model, a through groove 2.5 is formed on the protruding portion 2.1, and the through groove 2.5 is specifically a rectangular structure, and the second connecting member 3.4 is located in the through groove 2.5. Further, as Figure 3 and Figure 2 As shown in the state, the through groove 2.5 prevents the second connecting member 3.4 and the protruding portion 2.1 from interfering with each other.

[0030] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
