Description

Technical Field

[0001] The utility model relates to the technical field of oscillators, in particular to a cell culture oscillator. Background Art

[0002] An oscillator is an electronic component used to generate a repetitive electronic signal (usually a sine wave or square wave). The circuit it forms is called an oscillator circuit. An electronic circuit or device that converts direct current into an alternating current signal with a specific frequency is called an oscillator. There are many different types of oscillators. Based on the oscillation excitation method, they can be categorized as self-excited oscillators and externally excited oscillators; based on the circuit structure, they can be divided into RC oscillators, LC oscillators, crystal oscillators, and tuning fork oscillators; and based on the output waveform, they can be categorized as sine, square, and sawtooth waves. Oscillators are widely used in the electronics industry, medical care, scientific research, and other fields.

[0003] For example, Chinese utility model patent No. CN211246323U discloses a cell culture medium oscillator, comprising a bottom fixing frame, a drive motor, a rotating disk, a collision rod, a U-shaped frame, a positioning frame, a rectangular positioning block, a tightening spring, a longitudinal support rod, a transverse storage plate, a side support, a transverse protective frame structure, an auxiliary clamping frame structure, and a storage bucket. A buffer spring is positioned in the middle of the transverse sleeve and contacts the inner side of the limit plate at its left and right ends, thereby tightening the culture medium container inserted into the storage tube. The shaft of the protective cover is connected to the left and right sides of the upper portion of the transverse plate, thereby conveniently protecting the upper end of the container stored in the storage tube during use, thereby preventing the ingress of external dust or the escape of internal liquid.

[0004] The above patent can tighten the culture medium container inserted in the storage tube through the coordinated use of a buffer spring, a limit rod and a tightening rod. However, when the culture medium container is placed in the storage tube, the staff needs to manually bend the tightening rod to one side to facilitate the placement of the culture medium container in the storage tube. As a result, when the staff stores the culture medium container, they need to bend the tightening rod with one hand and use the other hand to take and place the culture medium container. It is impossible to take and place the culture medium container with both hands at the same time, which affects the efficiency of taking and placing the culture medium container. In addition, the above patent is not convenient for adjusting the oscillation amplitude of the culture medium container, and it is difficult to adjust the oscillation amplitude according to specific experimental requirements and cell types. There are certain limitations and it needs to be improved. Utility Model Content

[0026] 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.

[0027] Reference Figure 1-6 The utility model provides a cell culture oscillator: it includes a box body 1, two parallel guide rods 2 are fixedly connected between the two sides of the inner wall of the box body 1, an oscillation plate 3 is slidably sleeved between the outer surfaces of the two guide rods 2, and a driving mechanism for driving the oscillation plate 3 to move back and forth is further provided inside the box body 1, a storage rack 4 is fixedly connected to the top of the oscillation plate 3, a plurality of storage cavities 5 distributed in a rectangular array are opened on the top of the storage rack 4, a device slot is opened on the top of the storage rack 4 and on both sides of each storage cavity 5, and a clamping mechanism is provided inside the device slot;

[0028] The clamping mechanism includes a device box 6 embedded in the device slot, an electromagnet 7 is fixedly connected to the side of the device box 6 away from the storage cavity 5, and a permanent magnet 8 is slidably connected to the inside of the device box 6, a telescopic rod 9 is fixedly connected to the side of the permanent magnet 8 away from the electromagnet 7, the other end of the telescopic rod 9 is movable through the device box 6 and is fixedly connected to a splint 10, and buffering rubber pads 11 are fixedly connected to both sides of the permanent magnet 8. The setting of the buffering rubber pads 11 can play a buffering role when the permanent magnet 8 moves, preventing the permanent magnet 8 from violently colliding with the electromagnet 7 or the inner wall of the device box 6, thereby causing damage.

[0029] The driving mechanism includes a driving motor 13 and a nut 14 fixedly mounted on the box body 1. The output end of the driving motor 13 is fixedly connected to a rotating shaft 15. An oscillation wheel 16 is hingedly mounted on the outer surface of the rotating shaft 15. An oscillation ball 17 is movably inserted inside the oscillation wheel 16. The top of the oscillation ball 17 is fixedly connected to the middle position of the bottom of the oscillation plate 3 through a connecting block. The outer surface of the rotating shaft 15 is also fixedly connected to a limiting bar 18. An adjusting wheel 19 is slidingly sleeved between the outer surfaces of the rotating shaft 15 and the limiting bar 18. The setting of the limiting bar 18 can limit the adjusting wheel 19, so that the adjusting wheel 19 can only move along the axial direction of the rotating shaft 15. A connecting rod 20 is hingedly mounted between the adjusting wheel 19 and the oscillation wheel 16.

[0030] The internal thread of the nut 14 is connected to a threaded adjustment rod 21, one end of the threaded adjustment rod 21 movably passes through the box body 1 and is rotatably connected to an adjustment wheel 22, which is movably inserted into the interior of the adjustment wheel 19;

[0031] By rotating the threaded adjustment rod 21 to make it move inside the nut 14, the adjustment wheel 2 22 is driven to move, thereby pushing the adjustment wheel 1 19 to move through the movement of the adjustment wheel 22, and driving the oscillation wheel 16 to rotate through the connecting rod 20, thereby adjusting the inclination angle of the oscillation wheel 16, and the inclination angle of the oscillation wheel 16 is proportional to the oscillation amplitude of the vibration plate, thereby realizing the adjustment of the oscillation amplitude according to specific experimental requirements and cell types, thereby improving the adaptability of the device.

[0032] One end of the threaded adjustment rod 21 away from the second adjustment wheel 22 is fixedly connected to a hand wheel 23 , and the hand wheel 23 is provided to facilitate the user to screw the threaded adjustment rod 21 .

[0033] A door 24 is hingedly installed on the front of the box body 1, and a transparent observation window 25 is embedded in the door 24. A folding light-proof curtain 26 is also provided at the position corresponding to the transparent observation window 25 on the door 24. One end of the folding light-proof curtain 26 is fixedly connected to a moving rod 27. The setting of the transparent observation window 25 makes it convenient for the staff to observe the internal situation of the box body 1. By unfolding the folding light-proof curtain 26, the position of the transparent observation window 25 on the door 24 can be blocked to facilitate the light-proof culture of cells.

[0034] A control panel 12 is further provided on the front of the box body 1 , and the control panel 12 is electrically connected to the electromagnet 7 and the drive motor 13 respectively.

[0035] Working principle: During use, when it is necessary to take or place the culture solution container in the storage chamber 5, the user first opens the box door 24, and then turns off the power of all electromagnets 7 through the control panel 12. After the power is turned off, the magnetism of the electromagnet 7 disappears, and thus the repulsive force on the permanent magnet 8 disappears. At this time, the electromagnet 7 is attracted by the magnetic force of the permanent magnet 8 itself, and the electromagnet 7 is fixedly connected to the device box 6, so that the permanent magnet 8 moves to the side close to the electromagnet 7, and the clamping plate 10 is driven by the telescopic rod 9 to move toward the inside of the device slot, that is, to exit the storage chamber 5 and release the clamping fixation of the culture solution container, so that the user can take or place the culture solution container in the storage chamber 5. Through the setting of the automatic clamping mechanism, there is no need for manual operation by the user, freeing both hands, and it is convenient for the user to take or place the culture solution container with both hands. The operation is simple and convenient, saving time and effort, and effectively improving the efficiency of taking or placing the culture solution container.

[0036] When the culture medium container that needs to be oscillated is placed in the storage chamber 5, the electromagnet 7 is energized through the control panel 12, and the electromagnet 7 generates magnetism. The opposite magnetic poles of the electromagnet 7 and the permanent magnet 8 are the same. According to the principle of like magnetic poles repelling each other, a repulsive force is generated on the permanent magnet 8, causing the permanent magnet 8 to move to the side away from the electromagnet 7, and the splint 10 is driven by the telescopic rod 9 to move to the side close to the culture medium container stored in the storage chamber 5, so that the culture medium container is clamped and fixed by the splint 10, thereby improving the stability of the culture medium container;

[0037] Then, the door 24 is closed. If light-shielded culture is required, the user holds the moving rod 27 and moves it, thereby unfolding the folded light-shielding curtain 26 to block the position of the transparent observation window 25 on the door 24, so as to facilitate light-shielded culture of cells.

[0038] Next, the user adjusts the oscillation amplitude of the oscillation plate 3 (i.e., adjusts the tilt angle of the oscillation wheel 16) according to specific experimental requirements and cell types. The user holds the handgrip 23 and twists it, driving the threaded adjustment rod 21 to rotate and move inside the nut 14. The movement of the threaded adjustment rod 21 drives the adjustment wheel 2 22 to move, thereby driving the adjustment wheel 1 19 to move, and driving the oscillation wheel 16 to rotate through the connecting rod 20, thereby adjusting the tilt angle of the oscillation wheel 16. The tilt angle of the oscillation wheel 16 is proportional to the oscillation amplitude of the vibration plate.

[0039] When the inclination angle of the oscillation wheel 16 is adjusted, the drive motor 13 is started through the control panel 12, and the output end of the drive motor 13 rotates, driving the rotating shaft 15 to rotate, and then driving the oscillation wheel 16 to rotate. Since the oscillation wheel 16 is in a tilted state, it will drive the oscillation ball 17 to move left and right during its rotation, thereby driving the vibration plate to move back and forth left and right, thereby realizing the oscillation of the culture medium container placed on the storage rack 4.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
