Technical Field

[0001] The utility model relates to the technical field of cell culture fluid samplers, in particular to a sampler capable of preventing a culture dish from deflecting. Background Art

[0002] Pet stem cell culture medium is a liquid medium used to promote the growth and proliferation of pet stem cells. These media typically contain essential nutrients, growth factors, and other bioactive substances to support cell proliferation and differentiation. During experiments, samplers are used to extract samples from the culture medium for analysis or further processing. Common samplers include sterile syringes, sampling tubes, and cell separation tubes.

[0003] However, the existing samplers have the following disadvantages: since some samplers are provided with a rotatable disc, some circular holes are opened in the disc for placing culture dishes, and the diameter of the circular holes is fixed, but the diameter of the culture dishes may be different. When the culture dishes are placed in the circular holes, they may be offset due to the rotation of the disc, affecting the subsequent sampling work. Therefore, the existing samplers need to be improved. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. A limiting mechanism is set up, and the clamping block can be pushed to both sides first, so that the clamping block pushes the connecting rod and the slider to slide to one side on the outside of the slide rod. Then the slider squeezes the support spring, causing the support spring to contract. Then the culture dish is placed in the placement slot, and the support spring rebounds to drive the slider to slide on the slide rod.

First, pull the lifting plate to both sides so that the lifting plate drives the extension block to slide in the built-in groove of the fixed block and squeeze the reset spring, and extend the sampling tube from top to bottom into the round hole of the side frame. Then rotate the sampling tube clockwise so that the protrusions on both sides of the sampling tube are stuck in the arc groove. Then the reset spring rebounds and drives the extension block to retract into the built-in groove of the fixed block, so that the lifting plate is located below the piston rod. Then the No. 2 motor drives the screw rod to rotate, and the movable frame and the screw rod are threadedly engaged, so that the movable frame drives the lifting plate to move upward, and the piston rod can be lifted and pulled, which is convenient and fast for vertical sampling, thereby improving the practicality of the sampler.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1-6 The utility model provides a technical solution: a sampler with anti-drift culture dish, comprising a base 1 and a placement slot 8, a turntable 2 is installed above the base 1 through a bearing, a No. 1 motor 14 connected to the turntable 2 through a coupling is installed in the built-in slot of the base 1, the placement slot 8 is annularly opened on the upper surface of the turntable 2, one end of the base 1 is connected to a stand 4 through an electric push rod 3, a side frame 5 is fixed to the side of the stand 4 close to the turntable 2, a sampling cylinder 12 is movably sleeved on the inner side of the side frame 5, and a piston rod 10 is slidably sleeved on the inner side of the sampling cylinder 12.

[0024] See also Figure 1 、 Figure 2 and Figure 4 , the upper surface of the turntable 2 on both sides of the placement slot 8 is provided with a reserved slot, and a limiting mechanism 7 is provided in the reserved slot, and the limiting mechanism 7 includes a supporting spring 701, a slider 702, a connecting rod 703, a clamping block 704 and a slide rod 705. A slide rod 705 is installed in the reserved slot, and the outer side of the slide rod 705 is slidably sleeved with a supporting spring 701 and a slider 702. A connecting rod 703 is fixed on one side of the slider 702, and the end of the connecting rod 703 away from the slider 702 is connected to the clamping block 704, and a triangular notch is opened on one side of the clamping block 704.

[0025] During specific implementation, since some samplers are provided with a rotatable disc, some circular holes are opened in the disc for placing culture dishes, and the diameter of the circular hole is fixed, but the diameter of the culture dish may be different. When the culture dish is placed in the circular hole, it may be offset due to the rotation of the disc, affecting the subsequent sampling work. The clamping block 704 can be pushed to both sides first, so that the clamping block 704 pushes the connecting rod 703 and the slider 702 to slide to one side on the outside of the slide rod 705, and then the slider 702 squeezes the support spring 701, causing the support spring 701 to contract, and then the culture dish is placed in the placement slot 8. The support spring 701 rebounds and drives the slider 702 to slide on the slide rod 705. The slider 702 causes the connecting rod 703 to drive the clamping block 704 to clamp on the outside of the culture dish, stably clamping the culture dish, preventing the culture dish from deflecting, and improving the working stability of the sampler.

[0026] See also Figure 1 、 Figure 2 and Figure 5-Figure 7 A screw rod 13 is installed in the built-in groove of the stand 4 through a bearing, and a No. 2 motor 11 connected to the screw rod 13 through a coupling is installed above the stand 4. The outer thread of the screw rod 13 is sleeved with a movable frame 9, and the movable frame 9 is installed with a sampling mechanism 6 on both sides close to the piston rod 10. The sampling mechanism 6 includes a lifting plate 601, an extension block 602, a return spring 603 and a fixed block 604. The movable frame 9 is installed with a fixed block 604 on both sides close to the piston rod 10, and the inner side of the fixed block 604 is slidably sleeved with an extension block 602, and the outer side of the extension block 602 close to the fixed block 604 is sleeved with a return spring 603, and a lifting plate 601 is fixed to one side of the extension block 602. A circular hole is provided at one end of the side frame 5, and an arc groove is provided on the inner side of the circular hole.

[0027] During specific implementation, since the sampler requires the staff to pull the piston rod 10 to sample the culture dish, which is rather troublesome, the lifting plate 601 can be pulled to both sides first, so that the lifting plate 601 drives the extension block 602 to slide in the built-in groove of the fixed block 604 and squeeze the return spring 603, and the sampling tube 12 is extended from top to bottom into the circular hole of the side frame 5, and then the sampling tube 12 is rotated 90 degrees clockwise so that the protrusions on both sides of the sampling tube 12 are stuck in the arc groove, and then the return spring 603 rebounds and drives the extension block 602 to retract into the built-in groove of the fixed block 604, so that the lifting plate 601 is located below the piston rod 10, and then the No. 2 motor 11 drives the screw rod 13 to rotate, and the movable frame 9 is threadedly engaged with the screw rod 13, so that the movable frame 9 drives the lifting plate 601 to move upward, which can lift and pull the piston rod 10, facilitate and quickly take vertical samples, and improve the practicality of the sampler.

[0028] Working principle: When using the sampler with anti-drift culture dish, first install the sampling tube 12 on the side frame 5, and the electric push rod 3 drives the vertical frame 4 to move upward, and then place multiple culture dishes in the placement slot 8, and limit the position of the culture dishes by the limit mechanism 7, and then the No. 1 motor 14 drives the turntable 2 to rotate, and the turntable 2 drives the culture dishes to rotate, so that the culture dishes can be rotated to the bottom of the sampling tube 12, and the electric push rod 3 drives the vertical frame 4 to move downward, and then the No. 2 motor 11 and the screw rod 13 are used to adjust the height of the movable frame 9, so that the sampling mechanism 6 lifts the piston rod 10, and the sampling tube 12 takes samples in the culture dish, which improves the practicality and working stability of the sampler.
