[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] like Figure 1-Figure 2 As shown, the separable dual-energy bone densitometer comprises an upper chassis 1 and a lower trolley 5. In the present embodiment, the dual-energy bone densitometer realizes measurement by adopting the prior art; the chassis 1 is detachably connected to the trolley 5, a threaded hole 2a is provided at the bottom of the chassis 1, an upper and lower fixing bolt 3 connected to the threaded hole 2a is provided at the top of the trolley 5, a positioning ring 6 is provided at the top of the trolley 5, and a positioning pin 7 matched with the positioning ring 6 is provided at the bottom of the chassis 1; in the present embodiment, the number of the upper and lower fixing bolts 3, the positioning ring 6, the positioning pin 7 and the stud 2 is four.

[0020] The upper and lower fixing bolts 3 are provided with a handle 4; specifically, the handle 4 is a plum blossom-shaped handle. Of course, the shape of the handle 4 can also be other forms, as long as the upper and lower fixing bolts 3 can be conveniently rotated by hand.

[0021] The bottom of the chassis 1 has a stud 2 , and a threaded hole 2 a is arranged on the stud 2 .

[0022] An opening 5a is provided on the top of the trolley 5. Specifically, the opening 5a is a strip-shaped hole, which allows the upper and lower fixing bolts 3 to have a certain amount of back and forth adjustment space; the upper and lower fixing bolts 3 pass through the opening 5a and are threadedly connected to the threaded holes 2a to fix the chassis 1 and the trolley 5 together.

[0023] The chassis 1 includes a housing 1a and a base 1b. Specifically, the housing 1a is provided with a handle 1c, so as to facilitate taking and placing the chassis 1; the positioning pin 7 and the stud 2 are both installed on the base 1b.

[0024] The trolley 5 is a movable trolley, and the movable structure of the movable trolley adopts the existing technology.

[0025] The dual-energy bone densitometer is divided into an upper and lower structure. The upper case 1 and the lower trolley 5 can be quickly disassembled and assembled for use through the modified structure; the base 1b on the case 1 and the trolley 5 determine their ranges through the positioning pins 7 and the positioning rings 6, and the upper and lower fixing bolts 3 are rotated by using the handle 4 inside the trolley 5 to quickly and accurately fix the upper and lower structures; the device can be used as a whole or separately.

[0026] Traditional dual-energy bone densitometers are generally used indoors and cannot be used outdoors or in a portable manner. That is, the device is an integrated structure for transportation and use. This patented dual-energy bone densitometer can be used in both fixed and outdoor environments.

[0027] The conventional fixed structure cannot be disassembled. In the present invention, the upper and lower fixing bolts 3 can be rotated by the handle 4, that is, the upper and lower fixing bolts 3 can be disassembled to separate the chassis 1 and the trolley 5. The two can be quickly separated for disassembly and use.

[0028] 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.

[0029] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
