Description

A folding frame of an X-ray machine

technical field

The invention relates to a foldable frame, in particular to a foldable frame applied to medical X-ray machines.

Background technique

With the advancement of science and technology and the improvement of medical conditions, a variety of existing medical equipment is playing an extremely important role in various fields. Injuries and illnesses, and help doctors make scientific diagnoses. Therefore, X-ray machines are widely used in both central hospitals in urban areas and field hospitals in the field.

In particular, portable and mobile X-ray machines are responsible for the important tasks of treating the wounded, diagnosing traumatic fractures and other emergencies such as field wars or disaster relief. Therefore, how to transport and move the X-ray machine conveniently and quickly is particularly important.

In the existing technology, most of the X-ray machines in application are installed on the frame to facilitate the comprehensive and multi-angle diagnosis of patients. After the diagnosis is completed, they are disassembled from the frame for packaging and handling. Due to the frequent assembly and disassembly of the method, the work efficiency will undoubtedly be reduced, and what's more, the life of the patient will be endangered because of the delayed rescue time.

In the prior art, some designers have designed a movable frame of a portable X-ray machine to solve the problem that the X-ray machine can be moved without being disassembled from the frame, as shown in Figure 1a and Figure 1b, Portable X-ray machine movable support 1, it is mainly made up of the upper support 11 that is inverted U shape, two L-shaped bent pipes and is equipped with the lower support 12 of wheel 13, is arranged between this upper and lower support 11,12 The telescopic support device 14 is composed of a cantilever 15 pivotally connected to one end of the upper bracket 11, a telescopic brace device 16 arranged between the cantilever 15 and the upper bracket 11, and two load-bearing legs 17 connected to the forward end of the lower bracket 12, When moving the movable support 1, it is necessary to retract the cantilever 15 downwards, fold up the two load-bearing legs 17, and then tilt the movable support 1 as a whole to push and move.

However, as shown in Figure 1a, since one end of the telescopic brace device 16 is arranged on the upper bracket 11, the distance that the upper bracket 11 shrinks downward is limited, so that the overall bracket 1 cannot

Can achieve maximum folding; secondly, since the two load-bearing legs 17 are flexibly connected with the forward end of the lower bracket 12, the placement of the whole bracket 1 is unstable, especially when it is placed on an uneven ground It is easier to dump when it is on; finally, as shown in Figure 1b, because the overall frame 1 adopts a symmetrical double-frame structure, it is bulky and heavy and difficult to move, and its relatively complicated structure is also unsightly.

Therefore, how to design a frame for X-ray machines so as to avoid various shortcomings in the prior art is an urgent problem to be solved by those in the related field.
