[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] In order to solve the technical problem of low sampling efficiency caused by the existing deep-well plate, which requires one hand to pick up the deep-well plate during the sampling process and can only be sampled with the other hand, the utility model provides a deep-well plate fixing device, which can fix the deep-well plate on the human wrist or arm to free both hands and improve the sampling efficiency.

[0033] See also Figure 1As shown, a deep-well plate fixing device provided by the present invention includes a base 100, a wearable element 200 and a fixing part 300, the upper surface of the base 100 is formed with a placement groove 101 for placing the deep-well plate, and the placement groove 101 is adapted to the bottom surface of the deep-well plate, and the deep-well plate can be just fixed in the placement groove 101; one side of the wearable element 200 is an arc-shaped surface matching the curvature of the human wrist or arm, and the other side thereof is formed with a mounting plane 201 extending away from the wearable element 200, and the lower surface of the base 100 is mounted on the mounting plane 201; the fixing part 300 is fixed to the wearable element 200, and the fixing part 300 is wrapped around the human wrist or arm and fastened so that the deep-well plate is fixed on the human wrist or arm.

[0034] By adopting the technical solution of the present invention, the deep-well plate can be placed in the placement groove 101 of the base 100. Since the base 100 is installed on the wearable element 200, and the wearable element 200 is fixed to the human wrist or arm through the fixing part 300, the deep-well plate can be fixed to the human wrist or arm through the fixing device provided by the present invention. In this way, during the sampling process, both hands can be completely freed, and both hands can perform sampling work at the same time. The deep-well plate does not need to be placed in other positions, avoiding repeated picking up of the deep-well plate, which can greatly improve the sampling efficiency. The present invention is easy to use, and the sample will not fall out even if the wrist is slightly tilted, and it is highly practical.

[0035] In one embodiment, in order to meet the sampling needs of different scenarios and different experimenters, the base 100 and the wearable element 200 are designed to be rotatably connected, that is, the base 100 can be rotated at any angle on the wearable element 200.

[0036] Specifically, such as Figure 2 As shown, the fixing device provided by the present invention also includes a connecting member 400, the two ends of which are respectively connected to the base 100 and the wearable element 200, for realizing horizontal rotation of the base 100 on the wearable element 200.

[0037] In one embodiment, Figure 2As shown, the connecting member 400 includes a turntable 410 and a cover plate 420. The upper surface of the turntable 410 is fixedly connected to the lower surface of the base 100, and the lower surface of the turntable 410 is rotatably connected to the mounting plane 201. A through hole 201a is provided on the mounting plane 201, and a protrusion 421 is formed on one side of the cover plate 420. The protrusion 421 passes through the through hole 201a and is fixedly connected to the turntable 410 by screws. In this way, when the base 100 is rotated under the action of external force, the turntable 410 will be driven to rotate on the mounting plane 201. At the same time, the protrusion 421 moves with the turntable 410 in the through hole 201a, thereby realizing the rotation of the base 100 on the wearable element 200.

[0038] In one embodiment, the connecting member 400 further includes an elastic member (not shown) and a ball 430. Mounting holes 201b are provided on the mounting plane 201 and on both sides of the through hole 201a. The elastic member and the ball 430 are sequentially arranged in the mounting holes 201b from bottom to top, and the ball 430 is rollingly connected to the lower surface of the turntable 410.

[0039] In one embodiment, the combination Figure 3 and Figure 4 As shown, at least one limiting groove 411 is formed at a position on the lower surface of the turntable 410 corresponding to the mounting hole 201b. When the turntable 410 rotates on the mounting plane 201 to a position where the limiting groove 411 just corresponds to one of the mounting holes 201b, the ball 430 just falls into the limiting groove 411, and the turntable 410 drives the base 100 to be locked in the current position.

[0040] In one embodiment, the plurality of limiting grooves 411 are arranged along the circumference of the lower surface of the turntable 410 , and the number of the mounting holes 201 b is at least two, and at most one circle around the mounting plane 201 .

[0041] In one embodiment, Figure 5 As shown, the four sides of the base 100 are each formed with a blocking portion 110 extending upward, and the space surrounded by the four blocking portions 110 constitutes the placement groove 101.

[0042] In one embodiment, in order to make the base 100 more firmly arranged in the placement groove 101, the fixing device described in the present invention also includes at least one clip 500, which is hinged to one of the blocking parts 110, and one end of the clip 500 is clipped to a side surface of the deep-well plate.

[0043] In one embodiment, a pin hole with a slot is provided on the blocking portion 110, and the clamping member 500 is hinged in the pin hole through a pin shaft. The clamping member 500 can rotate along the pin shaft. Since the plastic material of the deep-hole plate is tough, the part protruding inward after the clamping member 500 rotates can clamp the side of the deep-hole plate, further stabilizing the deep-hole plate.

[0044] In one embodiment, one or more of the four blocking portions 110 may be hinged with a snap-fitting member 500 .

[0045] In one embodiment, connection holes 202 are respectively formed at both ends of the wearable element 200, and the fixing member 300 passes through the connection holes 202 and is fastened to the wrist or arm of the human body.

[0046] In one embodiment, the fixing member 300 is one or two straps.

[0047] In summary, the deep-well plate fixing device provided by the utility model can fix the deep-well plate on the human wrist or arm, completely freeing the hands, improving the sampling efficiency, and is easy to use. It is suitable for long-term use in places such as the wild and the field, without any physical burden, and the sample will not fall out even if the wrist is slightly tilted; and the deep-well plate can also be rotated arbitrarily to meet the sampling needs of different scenarios and different experimenters.

[0048] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
