[0004] However, when the vehicle is driven to a specific location for sampling and centrifugation, it is difficult to ensure that the working axis of the on-board centrifuge in the vehicle is vertical when the vehicle is in the specific location. Therefore, the parking position of the vehicle will have a certain impact on the working state of the on-board centrifuge. Utility Model Content

[0005] In response to the technical problem in the prior art that the centrifugal force on a vehicle has a certain impact on its working state due to the parking position of the vehicle, the utility model provides a vehicle-mounted sample centrifuge.

[0040] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0041] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but a person of ordinary skill in the art will recognize the application of other processes and / or the use of other materials.

[0042] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0043] Example:

[0044] like Figure 1 、 Figure 2 and Figure 3 As shown, this embodiment discloses a vehicle-mounted sample centrifuge, including a centrifuge body 10 and a connecting carrier 20, wherein the centrifuge body 10 is installed on the top of the connecting carrier 20, the bottom of the connecting carrier 20 is connected to the vehicle body, and the centrifuge body 10 is installed on the vehicle body through the connecting carrier 20.

[0045] Specifically, the connection carrier 20 includes a rotating portion 21, an adjusting portion 22, a positioning assembly, and a measuring assembly 24. The rotating portion 21 is mounted below the adjusting portion 22, and the centrifuge body 10 is mounted on top of the adjusting portion 22. The rotating portion 21 directly drives the adjusting portion 22 and the centrifuge body 10 to rotate. Furthermore, a positioning assembly is provided on the rotating portion 21 and the adjusting portion 22, and a measuring assembly 24 is provided on top of the adjusting portion 22. The positioning assembly can limit the rotation of the rotating portion 21 and the movement of the adjusting portion 22, while the measuring assembly 24 can directly indicate whether the centrifuge's working axis is in a vertical position.

[0046] In this embodiment, the centrifuge body 10 is mounted on the connection carrier 20 and then rotated by the rotating portion 21. When the centrifuge body 10 is rotated to an appropriate position, the adjusting portion 22 is used to adjust the centrifuge body 10 so that it deflects. The position of the centrifuge body 10 is measured by the measuring component 24, thereby causing the working axis of the centrifuge body 10 to be in a vertical state.

[0047] After adjusting the position of the centrifuge body 10, the positioning assembly constrains the rotating portion 21 and the adjusting portion 22 to prevent movement. This technical solution adjusts the working axis of the vehicle-mounted centrifuge to a vertical position by adjusting the connecting carrier 20, thereby reducing the impact of the vehicle's parking position on the operating state of the vehicle-mounted centrifuge.

[0048] In one specific embodiment:

[0049] like Figure 1 、 Figure 3 and Figure 4 As shown, the rotating portion 21 includes a connecting base plate 211 and a rotating shaft 212. The connecting base plate 211 is mounted on the vehicle body. The top surface of the connecting base plate 211 is flat, and a sunken mounting area is located in the middle of the top surface. Within this mounting area, one end of the rotating shaft 212 is rotatably connected via a bearing. The other end of the rotating shaft 212 is vertically upwardly disposed and connected to the bottom of the adjusting portion 22.

[0050] In this embodiment, a connecting bottom plate 211 is provided to connect with the vehicle body, and a rotating shaft 212 is used to realize 360° rotation of the adjusting portion 22 and the centrifuge body 10 without dead angles.

[0051] In another specific embodiment:

[0052] The adjusting part 22 includes a supporting base plate 221, a movable block 222, a screw 223 and a movable plate 224, wherein the bottom surface of the supporting base plate 221 is fixedly set on the top of the rotating part 21 (in this embodiment, the bottom surface of the supporting plate is fixedly connected to the top of the rotating shaft 212), the top surface of the supporting base plate 221 is also flat, and four movable blocks 222 are slidably arranged on the top surface of the supporting base plate 221.

[0053] Each of the four movable blocks 222 is provided with a threaded hole. Each of the four movable blocks 222 is fitted onto two screw rods 223, so that each screw rod 223 is fitted with two movable blocks 222. When the two screw rods 223 are mated with the four movable blocks 222, the two screw rods 223 are perpendicular to each other, and their axes remain parallel to the top surface of the support base 221. To directly drive the screw rods 223, a concave hexagonal drive portion is provided at each end of the screw rods 223.

[0054] Furthermore, the four movable blocks 222 are positioned at four locations along the working axis of the centrifuge body 10. When the support base 221 is horizontal, the four movable blocks 222 are equidistant from the working axis of the centrifuge body 10. Furthermore, the four ends of the two screws 223 are rotatably mounted on a support base fixedly mounted on the support base 221.

[0055] The movable plate 224 is placed on the top of all the movable blocks 222 , and a downwardly protruding and conical regulating body 225 is provided on the bottom surface of the movable plate 224 . The tops of all the movable blocks 222 mentioned above are in sliding contact with the surface of the regulating body 225 .

[0056] In this embodiment, the screw rod 223 can be directly driven to rotate by a tool such as a hexagonal wrench, thereby driving the two movable blocks 222 on the same screw rod 223 to move in the same direction, thereby causing the centrifuge body 10 and the movable block 222 to deflect with the tops of the other two movable blocks 222 as support points. Through this deflection and the rotation of the above-mentioned rotating part 21, the purpose of adjusting the working axis direction of the centrifuge body 10 is achieved.

[0057] Preferably, a metal ball 226 is provided on the top of the movable block 222 , and the ball 226 is used to contact the surface of the regulating body 225 at the bottom of the movable plate 224 , thereby reducing the wear of the movable block 222 on the surface of the regulating body 225 .

[0058] In another specific embodiment:

[0059] The measuring assembly 24 includes a support block 241, a crossbeam 242, a suspension rope 243, and a laser pointer 244. Multiple support blocks 241 are provided, all mounted on top of the adjustment portion 22 (in this embodiment, all support blocks 241 are mounted on top of the movable plate 224). Furthermore, the support blocks 241 are evenly distributed around the centrifuge, with gaps between adjacent support blocks 241. Furthermore, all support blocks 241 secure the centrifuge body 10 to the top of the adjustment portion 22.

[0060] A crossbeam 242 is provided between any two adjacent support blocks 241 , with both ends of the crossbeam 242 fixedly provided on the two support blocks 241 , and a hanging rope 243 is provided in the middle of the crossbeam 242 , with one end of the hanging rope 243 away from the crossbeam 242 hanging vertically downward.

[0061] One end of the laser pointer 244 is a light emitting end, and the other end is fixedly arranged on the end of the suspension rope 243 away from the beam 242, so that the light emitting end of the laser pointer 244 is also in a vertical downward state.

[0062] In this embodiment, when the rotating portion 21 and the adjusting portion 22 adjust the position of the centrifuge, it is possible to observe whether the light emitted by the laser pointer 244 is parallel to the working axis of the centrifuge body 10 .

[0063] More specifically, a coordinate sticker 245 is provided on the top surface of the adjustment portion 22. The coordinate sticker 245 is located directly below the laser pointer 244. When the working axis of the centrifuge body 10 is parallel to the light emitted by the laser pointer 244, that is, when the working axis of the centrifuge body 10 is in a vertical direction, the light emitted by the laser pointer 244 is exactly pointed at the center position of the coordinate sticker 245.

[0064] When installing the coordinate sticker 245, it is necessary to keep one coordinate axis of the coordinate sticker 245 parallel to the length direction of one of the screws 223. By setting the coordinate sticker 245, the position of the working axis of the centrifuge body 10 can be intuitively indicated for easy adjustment.

[0065] In another specific embodiment:

[0066] The positioning assembly includes a plurality of bolts 23 respectively provided on the rotating portion 21 and the adjusting portion 22 .

[0067] Among them, there are at least three bolts 23 passing through the aforementioned movable plate 224, and the bottom ends of all the bolts 23 passing through the movable plate 224 can be supported on the top surface of the aforementioned support bottom plate 221. At the same time, all the bolts 23 passing through the movable plate 224 are evenly distributed around the centrifuge body 10.

[0068] In addition, at least one bolt 23 passes through the supporting bottom plate 221 vertically downward, and the bottom end of the bolt 23 passing through the supporting bottom plate 221 can abut against the connecting bottom plate 211 .

[0069] In this embodiment, by providing a plurality of bolts 23 passing through the movable plate 224, the centrifuge body 10 can be supported after the adjustment portion 22 has adjusted its position. The movable plate 224 is fixed in position by resting the bottom ends of the bolts 23 against the support base 221. Similarly, resting the bottom ends of the bolts 23 passing through the support base 221 against the connecting base 211 prevents the adjustment portion 22 and the centrifuge body 10 from rotating.

[0070] In another specific embodiment:

[0071] In summary of the above technical solutions, the operation method of adjusting the position of the centrifuge body 10 in this technical solution is as follows:

[0072] First, the adjusting portion 22 and the centrifuge body 10 are rotated by the rotating portion 21 so that the light emitted by the laser pointer 244 is projected onto the coordinate axis in the coordinate sticker 245 that is parallel to the screw 223 .

[0073] Then, the rotating portion 21 is fixed by means of the bolts 23 passing through the supporting bottom plate 221 so that the adjusting portion 22 and the centrifuge body 10 do not rotate any further.

[0074] Then, the screw 223 parallel to the aforementioned coordinate axis is driven to rotate by a hexagonal wrench to move the two movable blocks 222 on the screw 223, thereby deflecting the movable plate 224 and the centrifuge body 10, and in this way, the light emitted by the laser pointer 244 is adjusted to move to the center position of the coordinate axis.

[0075] Finally, the adjustment portion 22 is fixed by means of the bolt 23 passing through the movable plate 224 to complete the adjustment.

[0076] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
