[0025] The present application embodiment discloses a new type of EP tube. Figure 1 and Figure 2 A novel EP tube includes a tube body 1, a tube cover 2 and a moving ring 3. The tube cover 2 covers the top opening of the tube body 1. The moving ring 3 is sleeved on the outer wall of the tube body 1. The moving ring 3 is provided with a cover opening component 7. The moving ring 3 is pushed to slide along the tube body 1, and then the tube cover 2 is opened by using the cover opening component 7, so that the cover can be easily opened by one-handed operation, thereby improving work efficiency.

[0026] Reference Figure 1 One end of the tube cover 2 extends outward to the top of the tube body 1. The tube cover 2 and the tube body 1 are integrally formed. A buckle 21 is fixedly arranged at the bottom of the other end of the tube cover 2. The buckle 21 is engaged with a groove corresponding to the top opening of the tube body 1. When the buckle 21 is in the engaged state, a gap is left between the outer wall of the tube body 1. Figure 2A first positioning block 5 is fixedly arranged on the outer wall of the tube body 1 near the opening, the bottom of the tube body 1 is conical, and a second positioning block 6 is fixedly arranged on the outer wall at the top position of the conical part of the tube body 1, and the straight line where the second positioning block 6 and the first positioning block 5 are located is parallel to the central axis of the tube body 1, and a positioning strip is also arranged on the straight line between the first positioning block 5 and the second positioning block 6, the positioning strip is fixedly connected to the outer wall of the tube body 1, and the two ends of the positioning strip are respectively abutted against the first positioning block 5 and the second positioning block 6 and connected as a whole.

[0027] Reference Figure 1 The movable ring 3 is annular, and both end faces of the movable ring 3 are arranged perpendicular to the central axis of the tube body 1, and the movable ring 3 fits the outer wall of the tube body 1; in order to facilitate the movable ring 3 to be quickly positioned to the opening position, refer to Figure 2 and Figure 3 A first positioning groove 11 is provided on the moving ring 3 corresponding to the first positioning block 5, and the first positioning groove 11 is inserted into the first positioning block 5. A second positioning groove 12 is provided on the moving ring 3 corresponding to the second positioning block 6, and the second positioning groove 12 is inserted into the second positioning block 6. A strip groove is provided on the moving ring 3 corresponding to the positioning strip, and the strip groove is inserted into the positioning strip. The first positioning groove 11, the second positioning groove 12 and the strip groove are all provided on the inner wall of the moving ring 3. The first positioning groove 11 passes through the end face of the moving ring 3 close to the top of the tube body 1, and the second positioning groove 12 passes through the end face of the moving ring 3 close to the bottom of the tube body 1. The two ends of the strip groove pass through the first positioning groove 11 and the second positioning groove 12 respectively.

[0028] When in use, force is applied to the moving ring 3, and the moving ring 3 moves along the direction of the positioning strip. When the moving ring 3 moves to the top of the tube body 1, the first positioning block 5 is inserted and abutted with the first positioning groove 11, so that the cover opening component 7 is aligned with the buckle 21 of the tube cover 2, and the moving ring 3 is quickly positioned to the position of the buckle 21, reducing unnecessary adjustment work; when the EP tube needs to be placed on the foam board for storage, the moving ring 3 is pushed to move to the bottom of the vertebral body of the tube body 1, and the second positioning block 6 is inserted and abutted with the second positioning groove 12, so as to prevent the moving ring 3 from sliding off the tube body 1 after reaching the vertebral part of the tube body 1, thereby realizing the limitation of the moving range of the entire moving ring 3.

[0029] The movable ring 3 is between the tube body 1 and the foam board, and the outer wall of the movable ring 3 abuts against the foam board. In order to increase the friction between the movable ring 3 and the foam board, anti-slip grooves are provided on the outer wall of the movable ring 3 to reduce the possibility of the EP tube slipping or scattering during operation.

[0030] During the entire movement of the mobile ring 3, since the inner wall of the mobile ring 3 is in contact with the outer wall of the tube body 1, the label paper 4 on the outer side of the tube body 1 can be compacted to prevent the label paper 4 from falling off, thereby reducing the probability of information loss and sample confusion. In addition, in order to facilitate viewing of the information on the label paper 4, an RFID reader or a QR code scanner can be installed on the mobile ring 3, which can wirelessly communicate with the RFID chip or QR code tag inside the EP tube.

[0031] Reference Figure 2 and Figure 4 The cover opening assembly 7 is located in the moving ring 3, and the cover opening assembly 7 includes a push rod 71, a force rod 72, a connecting rod 73 and a pressing piece 74 in sequence. The cover opening assembly 7 utilizes the principle of a lever, and the push rod 71 is fixedly connected to the force rod 72, and the push rod 71 is a short arm of the lever, and the force rod 72 is a long arm of the lever. The connection point between the push rod 71 and the force rod 72 serves as a lever support point, and the end of the push rod 71 away from the force rod 72 is inserted into the gap between the buckle 21 and the tube body 1. The push rod 71 applies an outward pushing force to the buckle 21, and the push rod 71 rotates in the direction of the principle tube body 1 with the connection point with the force rod 72 as the axis; the force rod 72 is arranged to be inclined to the central axis of the tube body 1, and the force rod 72 is inclined downward in the direction away from the tube body 1, leaving space for the rotation of the force rod 72.

[0032] Reference Figure 2 and Figure 4 The pressing piece 74 is located on the outer wall of the moving ring 3, and the pressing piece 74 does not protrude from the outer wall of the moving ring 3. The pressing piece 74 is arranged in a direction parallel to the central axis of the tube body 1. The pressing piece 74 fits with the operator's finger, and the pressing piece 74 and the moving ring 3 are connected by radial sliding along the moving ring 3, and the position of the moving outer wall corresponding to the pressing piece 74 is set into a concave structure; the connecting rod 73 is located between the pressing piece 74 and the force rod 72, and the two ends of the connecting rod 73 are respectively hinged to the pressing piece 74 and the force rod 72. The operator pushes the moving ring 3 to the opening position with one hand, at which time the push rod 71 has been inserted into the gap of the buckle 21, and then presses the pressing piece 74 with the finger, and drives the force rod 72 to rotate toward the direction close to the tube body 1 through the connecting rod 73, and then drives the push rod 71 to push the buckle 21 out. Through the lever operation, the experimenter can easily open the EP tube cover 2 with one hand without using both hands or applying too much force.

[0033] Working principle: When using the EP tube to absorb the chromosome suspension, first take the tube body 1, stick the label paper 4 with recorded information on the outer wall of the tube body 1, push the moving ring 3 with one hand to gradually move toward the top of the tube body 1. During the movement, the moving ring 3 presses the label paper 4 and the tube body 1 tightly. When it moves to the top of the tube body 1, continue to apply force to the pressing piece 74 with one hand. The pressing piece 74 easily pushes out the buckle 21 on the tube cap of the tube body 1 through the lever principle, releases the locking state between the tube cap and the tube body 1, and the tube cap opens; after the chromosome suspension is filled, put the tube cap back on, push the moving ring 3 away from the top of the tube body 1, and after the moving ring 3 reaches the position, take the tube body 1 and place it in the foam board for storage.
