Description

Technical Field

[0001] The invention belongs to the technical field of cell counters, and more specifically, particularly relates to a cell counter that is stably placed. Background Art

[0002] During the use of the cell counter, its stability and protection performance are crucial. However, the existing cell counters have many problems in practical applications.

[0003] Typically, cell counters lack effective stable connection measures and are prone to displacement or even tipping over when subjected to large shakes or external forces, affecting the accuracy of counting and the normal operation of the instrument.

[0004] For some portable cell counters, their fixing devices often occupy a large external space when not in use, which brings inconvenience to carrying and storing, and the fixing operation is relatively cumbersome and not convenient enough.

[0005] In terms of protection, existing cell counters have insufficient anti-fall protection measures on the front and back sides. When the instrument accidentally falls forward, there is a lack of effective blocking mechanism, which can easily cause damage to the instrument. There is also a lack of flexible and effective protective devices on the back of the instrument, making it difficult to cope with tilts and collisions at different angles. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a cell counter with stable placement to solve the above problems.

[0007] A stably placed cell counter comprises a cell counter, wherein a cross slot is penetrated through a side wall of the cell counter near the bottom, a gear is rotatably mounted on the top of the cross slot, bar gears are meshed on both sides of the gear, a fixing frame is fixedly mounted on the end of each bar gear, two bar gears and the fixing frame face oppositely, lower pressure plates are slidably mounted inside the two fixing frames, and suction cups are fixedly mounted below the two lower pressure plates.

[0008] Preferably, both side walls of the cross slide are provided with L-shaped slides, the side walls of the two bar gears are fixedly installed with L-shaped sliding frames, the two L-shaped sliding frames are installed in the L-shaped slide, the side walls of each L-shaped sliding frame and the end of the inner wall of the L-shaped slide are fixedly installed with a second spring, a first spring is fixedly installed between the top of each fixed frame and the bottom of the lower pressure plate, an insert rod is embedded in the interior of the L-shaped sliding frame located on the front side of the cell counter, and a third spring is fixedly installed between the end of the insert rod and the inside of the L-shaped sliding frame.

[0009] Preferably, a convex frame is installed on the front side wall of the cell counter, a fourth spring is fixedly installed between the side wall of the convex frame and the side wall of the cell counter, the end of the convex frame is in contact with the insertion rod, and the insertion rod is inserted into the cell counter, and a rotating shaft is fixedly installed inside the gear, and the upper and lower ends of the rotating shaft are rotatably connected to the inner wall of the cross slide.

[0010] Preferably, a magnetic protection frame is magnetically installed on the back of the cell counter, an L-shaped driving groove is opened at the lower part of the front side of the cell counter, and side sliding grooves are opened on the inner walls on both sides of the L-shaped driving groove, a first trapezoidal slider is installed vertically inside the L-shaped driving groove, and a second trapezoidal slider is installed horizontally inside the L-shaped driving groove, and side sliding plates are fixedly installed on the side walls of the first trapezoidal slider and the second trapezoidal slider, and each end of the side sliding plate is fixedly connected to the inner wall of the L-shaped driving groove.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In the present invention, the movement of the convex frame pushes the insertion rod at the end of the second spring backward. When the insertion rod moves out of the cell counter, the two second springs drive the two bar gears to slide through elastic force. The movement of the two bar gears drives the fixed frames at the ends to move. After the two fixed frames move out of the cell counter, the user presses the lower pressure plate downward, and the lower pressure plate drives the suction cup to move downward. The two suction cups are magnetically attracted to the desktop. At this time, the cell counter is stably connected to the desktop, and the cell counter can withstand greater shaking and external thrust, thereby greatly improving its own stability.

[0013] In the present invention, the movement of the two bar gears will drive the gear to rotate. Since the gear is meshed with the two bar gears, the two bar gears move the same distance and move synchronously, so that the forces on both sides of the cell counter can be kept the same. After the two fixing frames are moved outside the cell counter, the user presses down the lower pressure plate with force, and the lower pressure plate moves downward to compress the first spring to deform. When the suction cup is not in use, the first spring can maintain the height of the lower pressure plate, so that it is convenient for the fixing frame to drive the lower pressure plate and the suction cup to retract. The fixing frame and the suction cup are designed to be retractable into the cell counter, thereby improving the portability of the cell counter and reducing the external space occupied by the fixing frame and the suction cup when not in use.

[0014] In the present invention, both L-shaped sliding frames slide inside the L-shaped sliding groove. When the L-shaped sliding frame located at the front side of the cell counter moves to the convex frame, the third spring on the side wall of the L-shaped sliding frame drives the insertion rod to move forward through elastic force. At this time, the insertion rod is stuck in the cell counter. At this time, the two fixed frames are fixed. By using gears to link the two bar gears, the retraction operation can be facilitated, which greatly improves the convenience of operation. At the same time, the bar gear is designed to be fixable, so as to avoid falling during movement, thereby improving the safety of the equipment.

[0015] In the present invention, the first trapezoidal slider at the bottom of the cell counter will contact the desktop. Since the cell counter has weight, the cell counter is pressed down, and the first trapezoidal slider will gradually move upward. The first trapezoidal slider moves upward to squeeze the end of the second trapezoidal slider, and the second trapezoidal slider moves horizontally outward. At the same time, multiple fifth springs on the side walls of the first trapezoidal slider and the second trapezoidal slider are compressed, and the second trapezoidal slider moves outward beyond the cell counter. At this time, the second trapezoidal slider can play an anti-falling role for the front side of the cell counter. After the cell counter tilts forward at a certain angle, it will be stopped by the second trapezoidal slider, thereby improving the safety of the cell counter.

[0016] In the present invention, a plurality of magnetic protection frames are magnetically mounted on the back of the cell counter, and the magnetic protection frames can be magnetically attracted at any position on the back of the cell counter, thereby protecting the cell counter from tilting backwards and improving the safety of the cell counter from tilting backwards.

When the insertion rod 23 moves out of the cell counter 1, the two second springs 2 drive the two bar gears 15 to slide through the elastic force, and the two bar gears 15 move to drive the fixing frames 16 at the ends to move. After the two fixing frames 16 move out of the cell counter 1, the user presses the lower pressure plate 17 downward, and the lower pressure plate 17 drives the suction cup 19 to move downward. The two suction cups 19 are magnetically attracted to the desktop, and the two bar gears 15 and the fixing frames 16 face opposite directions. The lower pressure plates 17 are slidably installed inside the two fixing frames 16, and the suction cups 19 are fixedly installed below the two lower pressure plates 17.

[0026] L-shaped slide grooves 12 are provided on both side walls of the cross slide groove 11, and L-shaped slide frames 21 are fixedly installed on the side walls of the two bar gears 15. The two L-shaped slide frames 21 are installed in the L-shaped slide groove 12. The side walls of each L-shaped slide frame 21 and the end of the inner wall of the L-shaped slide groove 12 are fixedly installed with a second spring 2, so that the force on both sides of the cell counter 1 can be kept the same. After the two fixed frames 16 are moved to the outside of the cell counter 1, the user presses down the lower pressure plate 17 with force, and the lower pressure plate 17 The first spring 18 is compressed and deformed by moving downward. When the suction cup 19 is not in use, the first spring 18 can maintain the height of the lower pressure plate 17, thereby facilitating the fixing frame 16 to drive the lower pressure plate 17 and the suction cup 19 to retract. A first spring 18 is fixedly installed between the top of each fixing frame 16 and the bottom of the lower pressure plate 17. An insertion rod 23 is embedded in the interior of the L-shaped sliding frame 21 located on the front side of the cell counter 1, and a third spring 22 is fixedly installed between the end of the insertion rod 23 and the interior of the L-shaped sliding frame 21.

The end of the convex frame 24 fits with the insertion rod 23, and the insertion rod 23 is inserted into the inside of the cell counter 1. The two L-shaped sliding frames 21 both slide inside the L-shaped slide groove 12. When the L-shaped sliding frame 21 located on the front side of the cell counter 1 moves to the convex frame 24, the third spring 22 on the side wall of the L-shaped sliding frame 21 drives the insertion rod 23 to move forward through elastic force. At this time, the insertion rod 23 is stuck in the inside of the cell counter 1. At this time, the two fixed frames 16 are fixed, and the two bar gears 15 are linked by using the gear 14. The interior of the gear 14 is fixedly installed with a rotating shaft 13, and the upper and lower ends of the rotating shaft 13 are rotatably connected to the inner wall of the cross slide groove 11.

[0029] Working principle:

[0030] When using the cell counter 1, the user places the cell counter 1 on the desktop. In order to improve the stability of the cell counter 1 when in use, the user presses the convex frame 24 with his hand, and the convex frame 24 is forced to move and compress the fourth spring 25 to deform. The convex frame 24 moves to push the insertion rod 23 at the end of the second spring 2 backward. When the insertion rod 23 moves out of the cell counter 1, the two second springs 2 drive the two bar gears 15 to slide through the elastic force. The movement of the two bar gears 15 drives the fixed frame 16 at the end to move. After the two fixed frames 16 move out of the cell counter 1, the user presses the lower pressure plate 17 downward, and the lower pressure plate 17 drives the suction cup 19 to move downward. The two suction cups 19 are magnetically attracted to the desktop. At this time, the cell counter 1 is stably connected to the desktop, and the cell counter 1 can withstand large shaking and external thrust, which greatly improves its own stability.

[0031] When the two bar gears 15 move, the movement of the two bar gears 15 will drive the gear 14 to rotate. Since the gear 14 is meshed with the two bar gears 15, the two bar gears 15 move the same distance and move synchronously, so that the forces on both sides of the cell counter 1 can be kept the same. After the two fixing frames 16 are moved outside the cell counter 1, the user presses down the lower pressure plate 17 with force, and the lower pressure plate 17 moves downward to compress the first spring 18 to deform. When the suction cup 19 is not in use, the first spring 18 can maintain the height of the lower pressure plate 17, so that it is convenient for the fixing frame 16 to drive the lower pressure plate 17 and the suction cup 19 to retract. The fixing frame 16 and the suction cup 19 are designed to be retractable into the cell counter 1, so that the portability of the cell counter 1 can be improved and the external space occupied by the fixing frame 16 and the suction cup 19 when not in use can be reduced.

[0032] When the fixing frame 16 is not in use, the user pushes any one of the fixing frames 16 with force, and the movement of the fixing frame 16 drives the bar gear 15 to move, and the movement of the bar gear 15 drives the L-shaped sliding frame 21 of the side wall to move, and both L-shaped sliding frames 21 slide inside the L-shaped slide groove 12. When the L-shaped sliding frame 21 located at the front side of the cell counter 1 moves to the convex frame 24, the third spring 22 on the side wall of the L-shaped sliding frame 21 drives the insertion rod 23 to move forward through elastic force, and the insertion rod 23 is stuck in the cell counter 1. At this time, the two fixing frames 16 are fixed. The two bar gears 15 are linked by the gear 14, so that the retraction operation can be convenient, which greatly improves the convenience of operation. At the same time, the bar gear 15 is designed to be fixed, so as to avoid falling during movement, thereby improving the safety of the equipment;

[0033] When the cell counter 1 is placed on the desktop, the first trapezoidal slider 29 at the bottom of the cell counter 1 will contact the desktop. Since the cell counter 1 has weight, the cell counter 1 is pressed down, and the first trapezoidal slider 29 will gradually move upward. The first trapezoidal slider 29 moves upward to squeeze the end of the second trapezoidal slider 32, and the second trapezoidal slider 32 moves horizontally outward. At the same time, the plurality of fifth springs 31 on the side walls of the first trapezoidal slider 29 and the second trapezoidal slider 32 are compressed, and the second trapezoidal slider 32 moves outward beyond the cell counter 1. At this time, the second trapezoidal slider 32 can play a role in preventing the front side of the cell counter 1 from falling. After the cell counter 1 tilts forward at a certain angle, it will be stopped by the second trapezoidal slider 32, thereby improving the safety of the cell counter 1.

[0034] A plurality of magnetic protection frames 33 are magnetically mounted on the back of the cell counter 1. The magnetic protection frames 33 can be magnetically attracted at any position on the back of the cell counter 1, thereby protecting the cell counter 1 from tilting backwards and improving the safety of the cell counter 1 from tilting backwards.
