The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. As will be apparent to those of ordinary skill in the art, embodiments described herein can be combinable with other embodiments.

[0022] The utility model embodiment provides a kind of cell counter, as shown in Figures 1-5 The cell counter includes: base box 1, the top of the base box 1 is provided with cell counter main body 2;Liftable adjusting protective shell 3 is arranged on the base box 1, and the protective shell 3 is used to cover the cell counter main body 2;Symmetrically arranged mounting frame 4 in the base box 1 is height-adjustable;Roller 5 is rotatably installed on the mounting frame 4 for moving;Adjusting mechanism is arranged in the base box 1 for controlling the lifting of the protective shell 3.

[0023] In the embodiment, the cell counter is placed in a suitable position, and if it needs to be moved, the height of the mounting frame 4 in the base box 1 can be adjusted so that the roller 5 contacts the ground and moves through the roller 5.After use, the adjusting mechanism in the base box 1 is used to control the lifting of the protective shell 3 to cover the cell counter main body 2, and when used, the adjusting mechanism is used to lower the protective shell 3;The protective shell 3 is liftable and adjustable, and when the cell counter is not used, the cell counter main body 2 can be covered to effectively block the invasion of dust, microorganisms and other pollutants, avoid the contamination of the sample, ensure the accuracy of cell counting, reduce the possibility of deviation of experimental results, and solve the problem of insufficient protection design of the traditional cell counter;The mounting frame 4 is symmetrically arranged in the base box 1 and is height-adjustable, and the roller 5 is rotatably installed on the mounting frame 4, so that when the cell counter needs to be moved, the height of the mounting frame 4 is adjusted so that the roller 5 contacts the ground, the cell counter is conveniently moved, the mobility of the cell counter is improved, and the experimental operation is more flexible.

[0024] The adjusting mechanism comprises: a double-shaft motor 6 fixedly installed in the base box 1, an output shaft of the double-shaft motor 6 is fixedly provided with a transmission rod 7 through a shaft coupling; a screw rod 8 is symmetrically and rotatably installed in the base box 1 through bearings, an assembly block 9 is threadedly sleeved on the screw rod 8, one end of the assembly block 9 is fixedly connected with the protective shell 3; a first bevel gear 10 and a second bevel gear 11 are respectively fixedly installed on the transmission rod 7 and the bottom end of the screw rod 8, the first bevel gear 10 is engaged with the second bevel gear 11 for transmission.

[0025] In the embodiment, when it is needed to adjust the lifting of the protective shell 3, the double-shaft motor 6 fixedly installed in the base box 1 is started. The output shaft of the double-shaft motor 6 drives the transmission rod 7 to rotate through the shaft coupling, and the first bevel gear 10 at the bottom end of the transmission rod 7 rotates accordingly. Since the first bevel gear 10 is engaged with the second bevel gear 11 at the bottom end of the screw rod 8, the screw rod 8 is driven to symmetrically rotate in the base box 1 through the bearings. The assembly block 9 threadedly sleeved on the screw rod 8 moves up and down along the screw rod 8 with the rotation of the screw rod 8, and since one end of the assembly block 9 is fixedly connected with the protective shell 3, the lifting of the protective shell 3 is realized; the adjusting mechanism realizes the automatic lifting of the protective shell 3 through the cooperation of the double-shaft motor 6, the transmission rod 7, the screw rod 8 and the bevel gears. Compared with the manual adjusting mode, the operation convenience is greatly improved, the researchers do not need to manually and laboriously lift the protective shell, time and energy are saved, and the related operation of cell counting can be more efficiently performed; the threaded connection mode of the screw rod 8 and the assembly block 9 and the symmetrically arranged structure make the protective shell 3 more stable during lifting. The unstable conditions such as shaking and tilting of the protective shell 3 during lifting are avoided, the protective shell 3 can accurately cover or move away from the cell counter main body 2, so that the protective effect is better, the cell counter main body 2 is protected from external pollution, and the accuracy of cell counting is further ensured.

[0026] In the further preferred embodiment of the utility model, electric telescopic rods 12 are symmetrically and fixedly installed in the base box 1, recessed blocks 13 for assembling the mounting racks 4 are fixedly installed on output rods of the electric telescopic rods 12, and bolts 14 for limiting the mounting racks 4 are arranged on the recessed blocks 13.

[0027] In this embodiment, when it is necessary to adjust the height of the mounting rack 4 in order to control whether the rollers 5 contact the ground to achieve the movement or fixation of the cell counter, the electric telescopic rods 12 symmetrically fixedly installed in the base box 1 are started. The output rods of the electric telescopic rods 12 are extended or retracted, driving the recessed blocks 13 fixedly installed on the output rods to rise or fall. The mounting rack 4 is assembled on the recessed blocks 13 and changes the height along with the movement of the recessed blocks 13. When the mounting rack 4 reaches the appropriate height, the mounting rack 4 is fixedly positioned by tightening the bolts 14 on the recessed blocks 13 to prevent displacement during use. The setting of the electric telescopic rods 12 makes the height adjustment of the mounting rack 4 easy and accurate. The researchers can flexibly control the contact state of the rollers 5 with the ground according to the actual use scene. For example, when the cell counter needs to be moved, the mounting rack 4 is easily raised to make the rollers 5 contact the ground; when the cell counting operation is performed, the mounting rack 4 is lowered to stably place the instrument, greatly improving the flexibility of the use of the instrument and meeting the needs in different experimental environments; the symmetrically fixedly installed electric telescopic rods 12 ensure the stability of the mounting rack 4 during the lifting process. And the mounting rack 4 is further limited by the bolts 14 on the recessed blocks 13, further enhancing the stability of the mounting rack 4. This makes the cell counter maintain good stability in the moving or fixed state, avoids affecting the normal use of the instrument due to the shaking or instability of the mounting rack 4, ensures that the cell counting experiment can be smoothly performed, and improves the reliability of the experimental results.

[0028] In a further preferred embodiment of the utility model, the bottom of the protective shell 3 is fixedly installed with a plug-in block 15, and the top of the base box 1 is symmetrically provided with a plug-in groove matched with the plug-in block 15.

[0029] In this embodiment, when the protective shell 3 is lowered to protect the cell counter main body 2, the plug-in block 15 fixedly installed at the bottom of the protective shell 3 moves downward. The top of the base box 1 is symmetrically provided with a plug-in groove matched with the plug-in block 15, and the plug-in block 15 is accurately inserted into the plug-in groove. When the protective shell 3 rises and leaves the cell counter main body 2, the plug-in block 15 is pulled out of the plug-in groove; the close cooperation between the plug-in block 15 and the plug-in groove effectively improves the sealing between the protective shell 3 and the base box 1. When the protective shell 3 covers the cell counter main body 2, it can better block dust, microorganisms and other external pollutants from entering, provide more reliable protection for the cell counter main body 2, minimize the risk of sample contamination, and ensure the accuracy of the cell counting experimental results; this plug-in structure makes the protective shell 3 more stable when it is in the covering state. By inserting the plug-in block 15 into the plug-in groove, the horizontal displacement of the protective shell 3 is limited, preventing it from shaking or deviating when it is placed or subjected to slight external force, ensuring that the protective shell 3 always firmly protects the cell counter main body 2 and prolonging the service life of the instrument, providing a stable environment for cell counting work.

[0030] The utility model further preferably embodies that the bottom of base box 1 is symmetrically provided with a through hole 18, and the through hole 18 is matched with the mounting rack 4 for the mounting rack 4 to go in and out.

[0031] In the embodiment, when it is necessary to adjust the height of the mounting rack 4 to control whether the rollers 5 contact the ground to realize the movement or fixation of the cell counter, the mounting rack 4 moves up and down along with the extension and retraction of the electric telescopic rod 12. At this time, the through hole 18 symmetrically provided in the bottom of the base box 1 plays a role, and the mounting rack 4 goes in and out of the base box 1 through the through hole 18. In the process of rising of the mounting rack 4, the mounting rack 4 extends out of the base box 1 from the through hole 18; in the process of descending, the mounting rack 4 is retracted into the base box 1 through the through hole 18; the provision of the through hole 18 provides convenience for the height adjustment of the mounting rack 4. It enables the mounting rack 4 to smoothly move in and out of the base box 1, and realizes the free adjustment of the height of the mounting rack 4 in cooperation with the electric telescopic rod 12. The researcher can easily complete the conversion of the cell counter from the fixed state to the movable state without additional disassembly or installation of complex components, improves the convenience of the use of the instrument, and saves the operation time; the through hole 18 is matched with the mounting rack 4, and the rationality and integrity of the overall structure of the base box 1 are ensured. On the premise that the protection and support of the internal parts of the base box 1 are not affected, the movement demand of the mounting rack 4 is met. At the same time, the symmetrically provided through hole 18 ensures the stability and balance of the mounting rack 4 in the process of going in and out, avoids the movement of the mounting rack 4 being blocked or the stress being uneven due to the unreasonable setting of the through hole, and further improves the practicability and reliability of the cell counter as a whole.

[0032] In the further preferable embodiment of the utility model, the top of the protective shell 3 is symmetrically provided with a mounting block 16, and a handle 17 for gripping is hinged to the mounting block 16.

[0033] In the embodiment, when the lifting of the protective shell 3 needs to be manually operated, the researchers can hold the handle 17 hinged to the mounting block 16. The mounting block 16 is symmetrically opened at the top of the protective shell 3 to provide a stable mounting base for the handle 17. In operation, the handle 17 is turned to form a suitable angle with the protective shell 3, the force is conveniently applied, and then the protective shell 3 is moved upward or downward by means of the handle 17 to cover or expose the cell counter main body 2. After the operation is completed, the handle 17 can be turned to the position close to the top of the protective shell 3, without occupying additional space. The handle 17 greatly improves the convenience of the operation of the protective shell 3. When the adjusting mechanism fails or needs to be manually assisted, the researchers can easily lift the protective shell 3 through the handle 17, avoiding the inconvenience or damage caused by directly contacting the protective shell 3. Compared with directly pushing the protective shell 3, the force applied by the handle 17 is more uniform and labor-saving, which can effectively improve the operation efficiency. The symmetrically opened mounting block 16 and the hinged handle 17 are a kind of humanized design. The symmetric mounting block 16 ensures the balance of the handle 17 during operation, and no matter which side the researchers operate the handle 17, a stable grip feeling can be obtained. The hinged design allows the handle 17 to be stored when not in use, reducing the impact on the surrounding environment, and also avoiding damage to the handle 17 due to collision during the movement or placement of the instrument, improving the overall use experience of the cell counter.

[0034] In further preferred embodiments of the utility model, one side of the protective shell 3 is provided with an observation port, a visual observation window is arranged in the observation port, and anti-skid blocks 19 are symmetrically and fixedly installed at the bottom of the base box 1.

[0035] In the embodiment, the observation port is located on one side of the protective shell 3, and the visual observation window is arranged in the observation port. When the protective shell 3 covers the cell counter main body 2, the researchers can directly observe the working state of the cell counter main body 2 through the visual observation window without opening the protective shell 3. The anti-skid blocks 19 symmetrically and fixedly installed at the bottom of the base box 1 directly contact the plane when the cell counter is placed on the plane such as a laboratory bench, and play a role in stable support.

[0036] In further preferred embodiments of the utility model, a maintenance opening is arranged on the base box 1, a detachable maintenance plate is arranged in the maintenance opening, screws are arranged on the maintenance plate, and the screws are in threaded connection with the base box 1.

[0037] In the embodiment, when the parts inside the base box 1, such as the double-shaft motor 6, the electric telescopic rod 12 and the like, need to be inspected, repaired or replaced, the screws on the maintenance plate which are screwed with the base box 1 are unscrewed by using a tool. The maintenance plate is detached from the maintenance opening, and at this time, the related parts inside the base box 1 can be directly contacted and operated. After the maintenance work is completed, the maintenance plate is placed back to the position of the maintenance opening, and the screws are used to fix the maintenance plate on the base box 1, so as to ensure that the maintenance opening is closed.

[0038] To sum up, compared with the related art, through the synergistic effect of the protective shell 3, the adjusting mechanism, the electric telescopic rod 12, the plug-in block 15 and the like, the overall performance is improved. The protective shell 3 can be lifted and stably lifted through the plug-in block 15 and the insertion groove, effectively blocks the invasion of pollutants, and guarantees the accuracy of cell counting. The adjusting mechanism realizes the automatic lifting of the protective shell 3 by using the double-shaft motor 6 and the like, and improves the operation convenience. The electric telescopic rod 12 precisely adjusts the height of the mounting frame 4, cooperates with the rollers 5, makes the instrument move flexibly and be placed stably, meets the requirements of different experimental scenes, and solves the problems of insufficient protection and inconvenient operation of the traditional cell counter, and greatly improves the efficiency and reliability of cell counting work.
