[0023] Specifically, the cleaning and sterilization device 4 includes an electric lifting rod 41, a lifting frame 42, a collection box 43, a fan 45, a filter cloth 46 and a sterilization component 47. A lifting frame 42 is arranged on the outside of the detection support component 3, and the lifting frame 42 is connected to the detection support component 3 through the electric lifting rod 41. A collection box 43 is installed at the bottom of the detection support component 3 and at a position on the side of the detection support component 3 away from the electric lifting rod 41. A filter cloth 46 is installed on the inner side of the collection box 43. A plurality of fans 45 are installed on the side of the collection box 43 away from the detection support component 3. A sterilization component 47 is installed at the bottom of the lifting frame 42, close to the side of the detection support component 3 and at a position obliquely below the collection box 43.

[0024] By adopting the above technical solution, the bone densitometer can clean the surface of the detection support assembly 3 to a certain extent through the cooperation of the fan 45 and the filter cloth 46 when necessary, so as to better meet the working needs in different situations.

[0025] Specifically, the cleaning and sterilizing device 4 further includes a threaded block 44 , and the threaded block 44 is threadedly mounted on the top of the collecting box 43 .

[0026] By adopting the above technical solution, the staff can unscrew the threaded block 44 to remove the dust and other debris in the collection box 43 when needed, thereby reducing the difficulty of removing the dust and other debris in the collection box 43 and alleviating the labor burden of the staff.

[0027] Specifically, the sterilization component 47 includes a sterilization lamp 471 , and a plurality of sterilization lamps 471 are installed at a bottom of the lifting frame 42 , close to one side of the detection support component 3 and obliquely below the collection box 43 .

[0028] By adopting the above technical solution, the bone densitometer can sterilize the surface of the detection support assembly 3 through the sterilization lamp 471 when necessary, so as to better meet the working needs in different situations.

[0029] Specifically, the sterilization component 47 further includes a quartz glass shell 472 , and the quartz glass shell 472 is installed at a position on the bottom of the lifting frame 42 close to one side of the detection support component 3 and outside the multiple sterilization lamps 471 .

[0030] By adopting the above technical solution, the bone densitometer can protect each germicidal lamp 471 to a certain extent through the quartz glass shell 472, thereby reducing the possibility of accidental damage to each germicidal lamp 471.

[0031] When the present embodiment is used, when it is necessary to use a bone densitometer to detect the bone density of the arm, the bone densitometer is pushed, and the bone densitometer is moved to the working position through each moving assembly 8, and the electric hydraulic cylinder 5 on the base 1 is operated to drive the detection support assembly 3 to rise to the required height, and then the user places the arm on the detection support assembly 3, and then the detection is performed through the detection support assembly 3. After the detection is completed, the user takes off the arm, starts the electric lifting rod 41 in the cleaning and sterilization device 4, thereby driving the collection box 43 and other structures to move up and down through the lifting frame 42, and starts each fan 45. Under the action, dust and other debris on the detection support assembly 3 are sucked into the collection box 43, and then blocked by the filter cloth 46 and remain in the collection box 43. After cleaning, the electric lifting rod 41 is operated to drive the sterilization assembly 47 and other structures to the required height, and then each sterilization lamp 471 is started. The ultraviolet rays emitted by each sterilization lamp 471 pass through the quartz glass shell 472 to sterilize the detection support assembly 3. After the work is completed, the staff can unscrew the threaded block 44 when necessary to take out the dust and other debris in the collection box 43. The drawer 6 plays the role of storing items, and the sealing device 2 plays the role of blocking dust and other objects.

[0032] Example 2

[0033] The difference between this embodiment and embodiment 1 is that the limiting fixing device 7 includes a limiting plate 71, a limiting rod 72, a pedal 73 and a tension spring 74, the limiting plate 71 is installed on one side of the drawer 6, a pedal 73 is arranged between the multiple moving components 8, the limiting rod 72 is installed above the pedal 73 and on the inner side of the limiting plate 71, and multiple tension springs 74 are installed between the pedal 73 and the base 1 and on one side of the limiting rod 72.

[0034] By adopting the above technical solution, the bone densitometer can limit and fix the position of the drawer 6 to a certain extent through the cooperation of structures such as the limit plate 71 and the limit rod 72, thereby preventing the drawer 6 from accidentally sliding and reducing the possibility of item loss.

[0035] When the present embodiment is used, when the drawer 6 needs to be used, the staff steps on the pedal 73 in the limit fixing device 7, thereby driving the limit rod 72 to disengage from the limit plate 71 on the drawer 6, and then pulls out the drawer 6 to take out the items therein, and then pushes the drawer 6 back to its original position and releases the pedal 73. Under the action of each tension spring 74, the pedal 73 rises, thereby driving the limit rod 72 to insert into the limit plate 71, thereby preventing the limit plate 71 and the drawer 6 from moving, and the use is completed.

[0036] The structure and principle of the base 1 and the structure thereon, the sealing device 2, the detection support assembly 3 composed of a detection mechanism, a support mechanism and a locking mechanism, the electric hydraulic cylinder 5, the drawer 6, and the moving assembly 8 composed of a rotating seat and a moving wheel in the utility model have been disclosed in a dual-energy X-ray bone densitometer device disclosed in Chinese patent application No. 202022230684.8. Its working principle is that when checking the bone density of a person's arm, the detection mechanism is first adjusted by the electric hydraulic cylinder in the groove at the top of the base. After adjusting to a suitable position, the arm is placed on the support arm rod, and the plug on the fixing belt is inserted into the slot. The lock is clamped in the slot by the action of the spring to fix the arm and will not loosen. Then, the sliding rod slides in the inner cavity of the sliding seat to enable the arm to move left and right. The arm is positioned by a laser locator and X-rays are irradiated at the part to be detected. After the irradiation is completed, the lock is moved inward by pressing the left and right sides of the plug to unlock it. After unlocking, the arm is taken out, and the bone density test of the arm is completed.

[0037] The structure and principle of the sterilization lamp 471 in the utility model have been disclosed in an electric laparoscopic stapler power transmission mechanism disclosed in Chinese patent application number 202122604755.0. Its working principle is to use a lower mercury vapor pressure to emit two ultraviolet rays that are invisible to the naked eye. Its spectral lines mainly have two, one with a wavelength of 253.7 nanometers and the other with a wavelength of 185 nanometers. After the cells absorb the ultraviolet rays, they act on the genetic material in the cells. Through photochemical action, the energy of the ultraviolet rays can cause the genetic material to mutate, causing the bacteria to die immediately or be unable to reproduce, thereby achieving the purpose of sterilization.

[0038] The working principle and use process of the utility model are as follows: when it is necessary to use a bone densitometer to detect the bone density of the arm, the bone densitometer is pushed and moved to the working position through each moving component 8, and the electric hydraulic cylinder 5 on the base 1 is operated to drive the detection support component 3 to rise to the required height, and then the user places the arm on the detection support component 3, and then the detection is performed through the detection support component 3. After the detection is completed, the user takes off the arm, starts the electric lifting rod 41 in the cleaning and sterilization device 4, thereby driving the collection box 43 and other structures to move up and down through the lifting frame 42, and starts each fan 45. Under the action of each fan 45, dust and other debris on the detection support component 3 are sucked into the collection box 43, and then blocked by the filter cloth 46 and remain in the collection box 43. After the cleaning is completed, the electric lifting rod 41 is operated to drive the sterilization component 47 and other structures The structure moves to the required height, and then each sterilization lamp 471 is started. The ultraviolet rays emitted by each sterilization lamp 471 pass through the quartz glass shell 472 to sterilize the detection support assembly 3. After the work is completed, the staff can unscrew the threaded block 44 when necessary to take out the dust and other debris in the collection box 43. The drawer 6 plays the role of storing items, and the sealing device 2 plays the role of blocking dust and other objects; when the drawer 6 needs to be used, the staff steps on the pedal 73 in the limit fixing device 7, thereby driving the limit rod 72 to disengage from the limit plate 71 on the drawer 6, and then pulls out the drawer 6 to take out the items therein, and then pushes the drawer 6 back to its original position, releases the pedal 73, and under the action of each tension spring 74, the pedal 73 rises, thereby driving the limit rod 72 to insert into the limit plate 71, thereby preventing the limit plate 71 and the drawer 6 from moving, and the use is completed.
