Detailed Description

The following describes the embodiments of the present utility model in further detail with reference to the accompanying drawings.

As shown in fig. 1-5, the novel mixing device comprises a base 1 and a moving block 2, wherein the base 1 is provided with a groove 11, the bottom of the groove 11 is a first inclined surface, the moving block 2 is provided with a plurality of placing grooves 21 for placing sampling pipes 3, the bottom of the moving block 2 is provided with a second inclined surface corresponding to the first inclined surface, one side of the moving block 2 is provided with a hand-held part 22, and the hand-held part 22 penetrates through the base 1 to be exposed.

Therefore, in the actual use process, the hand-held part 22 is moved to drive the moving block 2 to move in the base 1 so as to mix the objects in the sampling tube 3 uniformly. Compared with a pipetting gun, the pipetting gun disclosed by the utility model has the advantages that the time and the labor can be saved, the thickness of the movable block 2 is larger than that of the pore plate, so that the position is better limited, and further, larger force can be applied, so that the time is saved, and secondly, the liquid in the sampling tube can be ensured to be horizontal due to the forward and backward movement of the inclined plane, so that the sprinkling condition is avoided, and meanwhile, the forward and backward movement and the up and down movement are simultaneously considered, so that the uniform mixing is ensured.

And if manual movement is adopted, the top of the hand-held part 22 is slotted, so that fingers can be placed and pulled more conveniently, and due to the forward and backward movement of the inclined plane, all manual movement can be performed by only applying a backward movement force, and then the moving block 2 can be moved forward due to gravity, so that labor can be saved.

And for the hand-held part 22, the side wall of the base 1 is provided with an opening 12, and the caliber of the opening 12 is larger than that of the hand-held part 22, so that the hand-held part 22 can move back and forth and up and down in the opening 12.

In the practical use process, the sampling tube 3 is generally about 100mm, and when one half or two thirds of the sampling tube 3 is positioned in the moving block 2, the condition that the sampling tube 3 is inclined due to movement is rarely generated, so that the height difference of one end of the inclined plane is less than or equal to 30mm, and the height of the moving block 2 is 80-90 mm, thereby ensuring that most of the sampling tube 3 is positioned in the moving block 2, and the condition that the sampling tube 3 is inclined due to movement is not generated.

As shown in fig. 3, four corners of the bottom of the base 1 are provided with suction cups 4, and the movement of the base 1 is avoided by suction of the suction cups 4.

Therefore, in the actual use process, the base 1 is limited to move through the arrangement of the sucker 4, and the situation that the moving block 2 moves and drives the base 1 to move is avoided.

As shown in fig. 1 and 2, the groove 11 is provided with a buffer plate 5 at both front and rear sides of the moving block 2, and a spring is provided between the buffer plate 5 and an inner wall of the groove 11.

Wherein the buffer plate 5 is made of a flexible and elastic material.

As shown in fig. 1 and 2, in order to avoid abrasion of the sampling tube 3 by the moving block 2, a flexible pad 61 is provided on the inner wall of the placement groove 21.

In order to avoid collision between the sampling tubes 3, a mounting groove 23 is formed in the top of the moving block 2, a second flexible pad 62 is arranged in the mounting groove 23, and a through hole 63 is formed in the second flexible pad 62 corresponding to the placement groove 21.

Thus, the sampling tube 3 is protected during actual use by the provision of the flexible pad.

Therefore, in the actual use process, the convex strips 111 are matched with the sliding grooves 24 so as to guide and limit the movement of the moving block 2.

As shown in fig. 4 and 5, the present utility model may be automatic, and the specific structure is that the two sides of the hand-holding part 22 are provided with the rods 221, and the base 1 is provided with the motor 7 and the rotating rod 71 at the side close to the hand-holding part 22, and the motor 7 is used for driving the rotating rod 71 to rotate.

Meanwhile, the rotating rod 71 and the rod 221 are connected through the push rod 72, and the push rod 72 is provided with a strip hole 721 corresponding to the rod 221, so that the rod 221 can move up and down in the strip hole 721 when the push rod 72 drives the rod 221 to move.

Therefore, in the actual use process, the motor 7 drives the rotating rod 71 to rotate and drives the push rod 72 to swing, so that the hand-held part 22 is driven to move forwards and backwards.

And the rod 221 is provided with the limiting piece 25, and the push rod 72 can be prevented from being separated from the rod 221 through the limiting piece 25. While the diameter of the rotating rod 71 between the push rods 72 is larger than the diameter of both ends of the rotating rod 71, thereby limiting the side not limited by the limiting member 25.
