Description

[0002] With the development of molecular biology, heterologous protein expression technology has gradually matured and been widely used. The expression of exogenous proteins requires the selection of appropriate expression hosts and expression elements, which requires the construction of a huge expression library from which to select the best expression toolbox. Cell culture plates can use less culture medium for high-throughput cell culture and screening of strains, cell lines and expression libraries, so they are widely used in the operation of constructing expression libraries.

[0003] Specifically, during the use of the cell culture plates, when multiple layers of cell culture plates are stacked, a pressing structure is required to press the multiple layers of stacked cell culture plates to ensure good sealing conditions between the multiple layers of stacked cell culture plates. However, when the current pressing structure is used specifically, it lacks necessary limiting support structures on both sides, causing the multiple layers of stacked cell culture plates to easily tilt sideways after being pressed, which not only fails to achieve a sealing effect, but also easily causes the multiple layers of stacked cell culture plates to topple over and be damaged.

The purpose of such a setting is that the movable seat 501 of the side limiting assembly 5 slides along the slide groove 401 and the clamping studs 503 are tightened to move the limiting baffle 505 to abut against the side parts of the multi-layered cell culture plate bodies 7. The moving method of the limiting baffle 505 is simple and easy to operate. At the same time, since the distance between the limiting baffles 505 at the two side positions is adjustable, it can adapt to the use of cell culture plate bodies 7 of different widths.

[0037] See also Figure 1-Figure 5As shown, the four corners of the top surface of the storage bottom plate 4 are vertically fixed with support rods 3 through connecting sleeves 301, and the top ends of the support rods 3 at the same side are horizontally fixed with the top plate 2 along the longitudinal direction through the connecting sleeves 301, and the top surfaces of the top plates 2 at both sides are installed with disassembly and assembly components 8. Specifically, the disassembly and assembly components 8 include a matching seat 807 and a fixing sleeve 801. Matching seats 807 are vertically fixed on both sides of the bottom surface of the mounting plate 1. The outer end surfaces of the matching seats 807 at the two sides are away from each other and limit holes 806 are horizontally provided. The top plates 2 at the two sides are A fixing sleeve 801 is vertically fixed in the middle of the top surface, and a matching groove 808 is vertically opened on the top surface of the fixing sleeve 801. The matching groove 808 corresponds to the matching seat 807 one by one and is vertically slidably matched. The outer end surfaces of the fixing sleeves 801 at both sides that are away from each other are horizontally opened with mounting holes 805. The mounting holes 805 are vertically connected with the corresponding matching grooves 808, and the mounting holes 805 are horizontally coaxially matched with the corresponding limiting holes 806. The mounting holes 805 are horizontally coaxially slidably matched with the limiting rods 803, and the limiting rods 803 at the two sides are The inner ends close to each other are lateraly slidably matched with the corresponding limiting holes 806, and the outer ends of the limiting rods 803 at the two side positions, which are far away from each other, extend out of the outer end faces of the corresponding fixing sleeves 801 and are coaxially fixed with handles 802. The part of the limiting rod 803 located between the corresponding handles 802 and the outer end faces of the fixing sleeves 801 is coaxially gap-matched with springs 804, and the two ends of the springs 804 are respectively fixedly connected with the corresponding handles 802 and the outer end faces of the fixing sleeves 801. The effect of such a setting is to vertically slide and match with the matching seat 807 and the matching groove 808. The horizontal sliding cooperation between the limiting rod 803 and the limiting hole 806 can removably fix the mounting plate 1 and the top pressing assembly 6 between the top plates 2 at the two side positions and above the multi-layered cell culture plate body 7. At the same time, the limiting rod 803 only needs to be pulled out of the limiting hole 806 to make the matching seat 807 vertically disengage from the matching groove 808, so that the mounting plate 1 and the top pressing assembly 6 can be removed from between the top plates 2 at the two side positions. The fixing combination and disassembly method of the mounting plate 1 and the top pressing assembly 6 between the top plates 2 at the two side positions is simple and easy to operate.

[0038] See also Figure 1-Figure 5As shown, a mounting plate 1 is fixed across the top of the disassembly assembly components 8 at both sides, and a top pressing component 6 for pressing down the multi-layered cell culture plate bodies 7 is installed in the middle of the mounting plate 1, and the mounting plate 1 and the top pressing component 6 are both detachably fixed between the top plates 2 at both sides through the disassembly assembly components 8. Specifically, the top pressing component 6 includes a lifting stud 602 and a pressure plate 605. The lifting stud 602 is vertically inserted in the middle of the mounting plate 1 in a threaded manner, and the bottom end of the lifting stud 602 is fixed to the top plate 2 at both sides. The shaft is rotatably connected to a bearing seat 604, and a pressure plate 605 is coaxially fixed to the bottom surface of the bearing seat 604, and the pressure plate 605 is located above the multi-layer stacked cell culture plate body 7 and between the limit baffles 505 on both sides. The advantage of this arrangement is that the pressure plate 605 can be driven to vertically lift and lower by screwing the lifting stud 602, and then the multi-layer stacked cell culture plate body 7 can be pressed or loosened by vertically lifting the pressure plate 605, and the pressing and loosening method of the multi-layer stacked cell culture plate body 7 is simple and easy to operate.

[0039] See also Figure 1-Figure 5 As shown, the lateral limiting assembly 5 is optimized as follows: the slide grooves 401 are all dovetail grooves or I-shaped grooves, and the top surfaces of the movable seats 501 are all flush with the corresponding tops of the slide grooves 401, so that the movable seats 501 can only slide laterally along the slide grooves 401, and at the same time, it is convenient to ensure that the top surface of the movable seat 501 will not raise the bottom of the cell culture plate body 7, and at the same time, the optional limiting baffles 505 are all vertically arranged rectangular long strips, and the inner end surfaces of the limiting baffles 505 at both sides facing each other are flush with the inner end surfaces of the corresponding movable seats 501. This arrangement facilitates the limiting baffles 505 to block and limit the multi-layer stacked cell culture plate bodies 7 from the side. Further optionally, the bottom end of the clamping stud 503 is coaxially fixed with an elastic clamping block 506 whose outer diameter is smaller than the aperture of the matching hole 504, and the top end of the clamping stud 503 is coaxially fixed with a handle 802 for easy holding. With such an arrangement, firstly, the elastic clamping block 506 is pressed against the bottom of the slide groove 401 to avoid damage to the bottom of the slide groove 401, and at the same time, the locking stability of the movable seat 501 can be improved by squeezing and deforming the elastic clamping block 506. Moreover, since the hand wheel 502 is coaxially fixed to the top end of the clamping stud 503, the clamping stud 503 can be smoothly turned by applying force by holding the hand wheel 502.

[0040] See also Figure 1-Figure 5As shown, the top pressing component 6 and the disassembly and assembly component 8 are optimized as follows. Specifically, with respect to the top pressing component 6, a rotating arm 601 is radially inserted at the top of the lifting stud 602 for easy holding, and the pressure plate 605 is a circular disc and the bottom end is coaxially covered with a buffer pad 606 fixed with a buffer material. With such an arrangement, it is firstly convenient to drive the lifting stud 602 to perform forward and reverse operations by holding the rotating arm 601, and at the same time, the buffer pad 606 directly contacts the top surface of the multi-layer stacked cell culture plate body 7 to have a certain buffering and protective effect. Further, optionally, the part of the lifting stud 602 extending out of the top surface of the mounting plate 1 is coaxially engaged with a locking nut 603, and the locking nut 603 is a hand-tightened knurled nut. With such an arrangement, it is convenient to lock the lifting stud 602 from rotating freely by twisting the locking nut 603 to press it against the top surface of the mounting plate 1, and at the same time, it is convenient for the locking nut 603 to be directly tightened and loosened by hand.

[0041] Specifically for the disassembly and assembly assembly 8, the horizontal cross-sectional shapes of the mating seat 807 and the mating groove 808 are both rectangular, so that the mating seat 807 has a good positioning and guiding design when it slides vertically along the mating groove 808. At the same time, the mating grooves 808 can be optionally blind grooves in the vertical direction, and the bottom ends of the mating seats 807 are in close contact with the bottom ends of the corresponding mating grooves 808. With this arrangement, in the process of the mating seat 807 sliding vertically along the mating grooves 808, when the limiting hole 806 slides vertically with the mating seat 807 to be coaxial with the limiting rod 803, an obvious prompt can be given by the bottom ends of the mating seat 807 being in close contact with the bottom ends of the corresponding mating grooves 808.

[0042] With the above structure, specifically in the process of pressing and pressing the multi-layered cell culture plate body 7, since the side limit components 5 are installed on both sides of the slide groove 401 of the storage bottom plate 4, the side limit components 5 at the two sides respectively abut against the two sides of the multi-layered cell culture plate body 7, the multi-layered cell culture plate body 7 can be limited and supported from the side, thereby avoiding the multi-layered cell culture plate body 7 from tilting sideways during the pressing process, and preventing the multi-layered cell culture plate body 7 from tipping over and being damaged. Specifically in operation, the movable seat 501 of the side limit component 5 slides along the slide groove 401, and the elastic pressing block 506 is pressed on the slide by screwing the pressing stud 503. The groove 401 bottom can make the limit baffle 505 move to abut against the side of the multi-layered cell culture plate body 7. The movement of the limit baffle 505 is simple and easy to operate, which is convenient for quickly moving the limit baffle 505 to abut against the side of the multi-layered cell culture plate body 7 for limited support. At the same time, since the distance between the limit baffles 505 at the two sides is adjustable, it can adapt to the use of cell culture plate bodies 7 of different widths. It should be noted that the same group of stacked multi-layered cell culture plate bodies 7 should maintain consistent specifications, which improves the general use range of the side limit assembly 5. Specifically, when the mounting plate 1 and the top pressing assembly 6 are combined and disassembled between the top plates 2 at the two sides, when they are combined, the mating seat 80 is used. 7 and the matching groove 808 vertically slidingly cooperate and the limiting rod 803 and the limiting hole 806 horizontally slidingly cooperate so that the mounting plate 1 and the top pressing assembly 6 can be detachably fixed between the top plates 2 at the two side positions and located above the multi-layered cell culture plate body 7. When disassembling, it is only necessary to hold the handles 802 at the two side positions and pull them outwards and make the limiting rods 803 disengage from the limiting holes 806 by the stretching of the springs 804, so that the matching seat 807 can be vertically disengaged from the matching groove 808 and the mounting plate 1 and the top pressing assembly 6 can be disassembled from between the top plates 2 at the two side positions. The fixing combination and disassembly method of the mounting plate 1 and the top pressing assembly 6 between the top plates 2 at the two side positions are simple and easy to operate, which is convenient for the mounting plate 1 and the top pressing assembly 6 to be disassembled. After the pressing assembly 6 is fixed between the top plates 2 at both sides, the multi-layered cell culture plate body 7 is pressed for use, and it is also convenient to remove the mounting plate 1 and the top pressing assembly 6 to smoothly pick up the multi-layered cell culture plate body 7. Specifically, in the use of the top pressing assembly 6, the pressing plate 605 can be driven to move up and down vertically by screwing the lifting stud 602, so that the multi-layered cell culture plate body 7 can be pressed or loosened by the vertical lifting of the pressing plate 605. The pressing and loosening method of the multi-layered cell culture plate body 7 is simple and easy to operate, which is convenient for pressing down the multi-layered cell culture plate body 7 for use, and at the same time, it is convenient for smoothly removing the multi-layered cell culture plate body 7 after loosening.
