Technical Field

[0001] The utility model relates to the technical field of biological equipment, in particular to an auxiliary 96-well plate sample adding base with adjustable slope. Background Art

[0002] 96-well plates are widely used in laboratories due to their high throughput. They are widely used in life sciences, medical research, and clinical diagnostics, primarily for handling trace amounts of liquids and various types of biochemistry, cytology, and molecular biology experiments.

[0003] When existing laboratory personnel add reagents or samples to a 96-well plate, due to the large number of wells in the 96-well plate and the large amount of experimental samples, and due to the height of the 96-well plate itself and the visual angle of the human eye, if the 96-well plate is placed flat, it will affect the experimenter's observation of the reagent addition, which may easily lead to wrong addition, omission or over-addition, resulting in inaccurate experimental data. If the experimenter wants to observe the addition of reagents or samples, he or she often needs to pick up the 96-well plate to check for confirmation. This operation affects both experimental efficiency and experimental safety, and is still prone to wrong addition, omission or over-addition, affecting the accuracy of the experimental data.

[0004] To this end, we propose an auxiliary 96-well plate sample loading base with adjustable slope to solve the above-mentioned technical problems existing in the prior art. Utility Model Content

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: an auxiliary 96-well plate loading base with adjustable slope, comprising a base plate and a 96-well plate bracket, the 96-well plate bracket being hingedly connected to the base plate, and the opposite end of the 96-well plate bracket connected to the base plate being hinged with a connecting piece, the connecting piece being connected to the adjustment component so as to be movably connected up and down, and being fixedly supported on the base plate by the adjustment component; the adjustment component comprises a screw and a rotating wheel fixedly arranged on the rod body of the screw, the screw being threadedly connected to the connecting piece, and the screw being located at the upper part of the rotating wheel and being provided with a range for the connecting piece to move up and down, the base plate is provided with a plurality of linearly distributed plug holes at the lateral movement position of the screw, and the plug holes are plugged into and matched with the bottom end of the screw.

[0007] Furthermore, the outer surface of the rotating wheel is provided with a concave-convex texture.

[0008] Furthermore, anti-slip pads are bonded and fixed at the four corners of the bottom surface of the base plate.

[0009] Furthermore, a 96-well plate clamping assembly is provided on the 96-well plate bracket.

[0010] Furthermore, the 96-well plate clamping assembly includes upper and lower clamping plates arranged opposite to each other and a gear rotatably connected to the upper center of the 96-well plate bracket. The two clamping plates are respectively connected to a serrated skateboard. The two serrated skateboards are respectively located on both sides of the gear and arranged in parallel and are respectively engaged with the gear. A spring is fixedly connected between the clamping plate and the central axis of the gear, and the serrated skateboard slides on the 96-well plate bracket.

[0011] Furthermore, the 96-well plate bracket is provided with an open groove for relative sliding of the two splints, the side of the serrated slide relative to the gear has a convex edge protruding outward, and the bottom side wall of the open groove is provided with a limiting groove that slides with the convex edge.

[0024] 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 in conjunction with the 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.

[0025] In view of the problems existing in the prior art, the present invention provides an auxiliary 96-well plate sample loading base with adjustable slope. The present invention is described in detail below with reference to the accompanying drawings.

[0026] See Figures 1-8 As shown, the technical solution adopted in this specific embodiment is: an auxiliary 96-well plate loading base with adjustable slope, comprising a base plate 1 for placing on a desktop and a 96-well plate bracket 2, the 96-well plate bracket 2 is hinged on the base plate 1 at an angle, and the opposite end of the 96-well plate bracket 2 connected to the base plate 1 is hinged with a connecting piece 3, the connecting piece 3 can be connected to the adjustment component 4 so as to be movable up and down, and is fixedly supported on the base plate 1 through the adjustment component 4, the adjustment component 4 adjusts its connection position on the base plate 1 as the connecting piece 3 moves up and down. Specifically, a plurality of fixed points are provided on the base plate 1 for the adjustment component 4 to move laterally.

[0027] It should be specifically explained that the adjustment component 4 includes a screw 41 and a rotating wheel 42 arranged on the rod body of the screw 41. The screw 41 is located on the upper part of the rotating wheel 42 and reserves a range for the connecting piece 3 to move up and down. A screw hole 31 is vertically penetrated on the connecting piece 3 to cooperate with the screw 41. By holding the rotating wheel 42 and rotating the screw 41 in the reverse or forward direction, the connecting piece 3 can be moved up and down on the screw 41, thereby realizing the adjustment of the inclination angle of the 96-well plate bracket 2. The connecting piece 3 always remains parallel to the base plate 1 during the up and down movement.

[0028] As a preferred embodiment of this embodiment, the outer surface of the rotating wheel 42 is provided with a concave-convex texture to increase the friction coefficient and avoid slipping during rotation.

[0029] It should be specifically explained that when the connecting piece 3 moves up and down, the left and right positions of the adjusting component 4 should also change at the same time. Therefore, the base plate 1 is provided with a plurality of linearly distributed plug holes 11 at the lateral movement position of the screw 41, and the plug holes 11 are plugged into and fitted with the bottom end of the screw 41.

[0030] As a preferred embodiment of the present invention, anti-skid pads 12 are bonded and fixed to the four corners of the bottom surface of the base plate 1. The provision of the anti-skid pads 12 improves the anti-skid effect of the base plate 1 and prevents the base plate 1 from sliding easily during use.

[0031] It should be specifically explained that a 96-well plate clamping assembly 5 is provided on the 96-well plate bracket 2, and the 96-well plate clamping assembly 5 includes upper and lower clamping plates 51 arranged opposite to each other and a gear 52 rotatably connected to the upper center of the 96-well plate bracket 2. The two clamping plates 51 are respectively connected to a slide plate 511 with serrations, and the two slide plates 511 with serrations are respectively arranged in parallel on both sides of the gear 52 and are respectively meshed with the gear 52. A spring 53 is fixedly connected between the clamping plate 51 and the center axis of the gear 52.

[0032] It should be specifically explained that the 96-well plate bracket 2 is provided with an open groove 21 for the two clamps 51 to slide relative to each other, the serrated slide 511 has an outwardly protruding convex edge 5111 on the side relative to the gear 52, and the bottom side wall of the open groove 21 is provided with a limiting groove 211 that slides with the convex edge 5111.

[0033] As a preferred embodiment of this embodiment, elastic clamping pads 512 are bonded and fixed to the opposing clamping surfaces of the two clamping plates 51. The provision of the elastic clamping pads 512 can reduce mechanical damage to the 96-well plate while enhancing the clamping effect. Furthermore, the clamping surfaces of the elastic clamping pads 512 are provided with anti-slip grooves.

[0034] Specific working principle: When in use, first adjust the inclination angle of the 96-well plate holder 2 according to the user's usage habits. Specifically, by holding the rotating wheel 42 and rotating the screw 41 forward or reverse, the connection position of the connecting piece 3 on the screw 41 is changed to increase or decrease the inclination angle of the 96-well plate holder 2. When the appropriate angle is adjusted, the lower end of the screw 41 is plugged into the appropriate plug hole 11. After the adjustment is completed, the 96-well plate used in the experiment is installed and fixed on the 96-well plate holder 2. Specifically, by pulling the clamping plate 51, the two clamping plates are changed. The distance between the plates 51, after placing the 96-well plate between the two clamping plates 51, loosen the clamping plates 51, and the spring 53 acts to clamp the two clamping plates 51, thereby fixing the 96-well plate. During the experiment, the user can adjust the inclination angle of the 96-well plate holder 2 according to his or her own usage habits, so as to more clearly view the well positions where reagents or samples are added, thereby improving the experimental efficiency and accuracy. Of course, during use, the user can still continue to adjust the inclination angle of the 96-well plate holder 2 through the screw 41, which is more flexible to use.
