DETAILED DESCRIPTION

[0035] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0036] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0037] Example 1:

[0038] like Figures 1-10As shown, a quick locking structure applied to a perfusion transfer box includes a perfusion transfer box body, the perfusion transfer box body includes a main base 100 and a box cover 200, the main base 100 includes a first positioning portion 6 and a limiting groove 7, and the box cover 200 includes a second positioning portion 8 and a pressure block roller component 5; the main base 100 and the box cover 200 cooperate through the first positioning portion 6 and the second positioning portion 8, and the pressure block roller component 5 and the limiting groove 7 to achieve locking or opening of the perfusion transfer box body.

[0039] The first positioning portion 6 includes a locking groove 61 and a limiting protrusion 62 , and the second positioning portion 8 includes a locking tongue 81 and a horizontal notch 82 . The locking tongue 81 is inserted into the locking groove 61 , and the limiting protrusion 62 is inserted into the horizontal notch 82 .

[0040] The box cover 200 includes an upper cover 1 and an inner lining part 2. A knob 3, a push rod part 4 and a pressure block roller part 5 are sequentially arranged between the upper cover 1 and the inner lining part 2 from top to bottom. The push rod part 4 and the pressure block roller part 5 are symmetrically arranged on both sides of the knob 3 with the knob 3 as the center. Accordingly, two push rod parts 4 and two pressure block roller parts 5 are respectively arranged between the upper cover 1 and the inner lining part 2. The knob 3 includes an elliptical part 31. When the knob 3 is rotated, the long axis of the elliptical part 31 contacts the push rod part 4 and drives the push rod part 4 and the pressure block roller part 5 to press down in sequence, thereby realizing the contact between the pressure block roller part 5 and the limiting groove 7.

[0041] Specifically, the lock tongue 81 is inserted into the lock groove 61, and the limiting protrusion 62 is inserted into the horizontal notch 82. The lock groove 61 and the lock tongue 81 cooperate with each other, and the horizontal notch 82 and the limiting protrusion 62 cooperate to limit the vertical movement between the main base 100 and the box cover 200; further, the pressure block roller component 5 is pressed into the limiting groove 7, and the pressure block roller component 5 conflicts with the limiting groove 7, generating a large friction force in the horizontal direction, thereby limiting the horizontal movement between the main base 100 and the box cover 200; so that the box cover 200 is locked on the main base 100.

[0042] Compared with the prior art, the present invention realizes the locking or opening of the perfusion transfer box body through the cooperation of the first positioning part 6, the second positioning part 8, the pressure block roller component 5 and the limiting groove 7, which is simpler and more convenient to operate, and also ensures the sealing of the perfusion transfer box.

[0043] In order to ensure that the knob 3 can be rotated to the specified position and does not deflect in the event of an accidental touch, thereby ensuring the sealing between the main base 100 and the box cover 200, the upper cover 1, the lining component 2 and the knob 3 are structured as follows:

[0044] The upper cover 1 includes a stepped hole 11 and a limiting ring 12, wherein the limiting ring 12 is located inside the upper cover 1 and is arranged around the stepped hole 11; the knob 3 includes a stepped portion 32 and a stopper 33, wherein the stepped portion 32 is adapted to the stepped hole 11, and the stopper 33 is limited by the limiting ring 12.

[0045] The lining component 2 includes a compression spring 21, a lining pin 22 and a lining 23. The lining 23 includes a support column 231 at the top and a long pin hole 232 symmetrically arranged on the support column 231. The compression spring 21 is located in the support column 231, and the lining pin 22 is located in the long pin hole 232. The top of the compression spring 21 conflicts with the bottom of the lining pin 22.

[0046] The elliptical portion 31 includes a latching position 311 that can accommodate the lining pin 22. The latching position 311 limits the lining pin 22. In this embodiment, there are four latching positions 311, two of which correspond to the long axis of the elliptical portion 31 and two correspond to the short axis of the elliptical portion 31.

[0047] Specifically, the stepped portion 32 of the knob 3 is inserted into the stepped hole 11 , and the elliptical portion 31 of the knob 3 covers the support column 231 , so that the knob 3 is fixed between the upper cover 1 and the lining component 2 .

[0048] Further, the knob 3 is rotated 90° clockwise, and the short axis of the elliptical portion 31 toward the push rod component 4 is converted into the long axis of the elliptical portion 31, and the lining pin 22 is locked from the locking position 311 opposite to the short axis of the elliptical portion 31 into the locking position 311 opposite to the long axis of the elliptical portion 31, wherein the compression spring 21 at the lower end of the lining pin 22 applies a reaction force to the lining pin 22, so that the lining pin 22 is completely locked in the locking position 311.

[0049] Similarly, the knob 3 rotates 90° counterclockwise, and the long axis of the elliptical portion 31 facing the push rod component 4 is converted into the short axis of the elliptical portion 31, and the lining pin 22 is locked from the locking position 311 opposite to the long axis of the elliptical portion 31 to the locking position 311 opposite to the short axis of the elliptical portion 31.

[0050] In the present invention, due to the coordinated use of the latch 311, the lining pin 22 and the compression spring 21, the knob 3 can be accurately rotated to the specified position, and will not be easily rotated due to accidental external force, resulting in the main base 100 and the box cover 200 opening.

[0051] The knob 3 of the utility model realizes the locking or opening of the perfusion transfer box body through two opposite-direction actions, and is not prone to misoperation.

[0052] The lining 23 includes a push rod installation groove 233 and a pressure block roller groove 234 . A tension spring limiting column 235 is provided at the upper end of the push rod installation groove 233 .

[0053] The push rod component 4 includes a push rod pin 41, a tension spring 42 and a push rod 43. The push rod pin 41 is fixed on the push rod 43. One end of the tension spring 42 is connected to the push rod pin 41, and the other end of the tension spring 42 is connected to the tension spring limiting column 235.

[0054] Specifically, the middle part of the push rod 43 is hollowed out, and the push rod 43 is set in the push rod installation groove 233. The push rod pin 41 and the tension spring 42 are both located in the hollow part of the middle part of the rod 43. When the push rod 43 is subjected to the downward pressure of the long axis of the elliptical part 31, the push rod 43 is pressed down, and at the same time, the tension spring 42 is stretched.

[0055] Similarly, when the major axis of the elliptical portion 31 is converted into the minor axis of the elliptical portion 31 , the push rod 43 returns to its original position under the reaction force of the tension spring 42 .

[0056] The push rod mounting groove 233 of the present invention plays a role in positioning and guiding the push rod 43, which not only enables the push rod 43 to be stably fixed between the upper cover 1 and the lining component 2, but also enables the push rod 43 to be pressed downward along the direction of the push rod mounting groove 233.

[0057] Due to the coordinated use of the push rod pin 41, the tension spring 42 and the push rod 43, the push rod 43 can be pressed down to a specified position under the action of an external force, and the push rod 43 can return to its original position after the external force disappears, making it convenient to repeatedly lock or open the perfusion transfer box body.

[0058] The pressing block roller groove 234 includes a first notch 2341 , a second notch 2342 and a column 2343 . The column 2343 is located between the first notch 2341 and the second notch 2342 , and the column 2343 protrudes toward the main base 100 .

[0059] The pressure block roller component 5 includes a pressure block 51, a rotating wheel 52, an anti-slip ring 53 and a spring 54. The pressure block 51 includes a hook 511, a protrusion 512, an inner groove 513 and an arc groove 514. The hook 511 is engaged with the first notch 2341, so that the pressure block roller component 5 can be fixed on the pressure block roller groove 234. The protrusion 512 passes through the second notch 2342, which facilitates the up and down movement of the protrusion 512 after being subjected to external force. The rotating wheel 52 is arranged in the arc groove 514, and the anti-slip ring 53 is arranged on the outer surface of the rotating wheel 52. The anti-slip ring 53 prevents the rotating wheel 52 from slipping in the limiting groove 7, thereby increasing the friction between the rotating wheel 52 and the limiting groove 7. A spring 54 is also arranged between the inner groove 513 and the column 2343.

[0060] Specifically, when the pressure block roller component 5 is subjected to the downward pressure of the push rod 43, the pressure block 51, the driving wheel 52, and the anti-slip ring 53 are pressed down in sequence. At the same time, the spring 54 is stretched, and the bottom of the pressure block roller component 5 contacts the bottom of the limiting groove 7, thereby limiting the horizontal movement of the box cover 200 on the main base 100.

[0061] Similarly, when the major axis of the elliptical portion 31 is converted into the minor axis of the elliptical portion 31 , the pressing block 51 , the rotating wheel 52 and the anti-slip ring 53 return to their original positions under the reaction force of the spring 54 .

[0062] The utility model adopts elastic wire components such as the tension spring 42 and the spring 54, so that the parts connected thereto can be quickly reset under the reaction force of the tension spring 42 and the spring 54, thereby facilitating the opening of the infusion transfer box body.

[0063] Working principle: The lock tongue 81 of the box cover 200 is inserted into the lock groove 61 of the main base 100. At the same time, the limiting protrusion 62 of the main base 100 also enters the horizontal notch 82 of the box cover 200; the knob 3 is rotated 90° clockwise, and the short axis of the elliptical portion 31 facing the push rod 43 is converted into the long axis of the elliptical portion 31. The long axis of the elliptical portion 31 presses down the push rod 43, and the push rod 43 presses down the pressure block 51, and then the rotating wheel 52 and the anti-slip ring 53 enter the limiting groove 7 and conflict with the limiting groove 7, thereby realizing the connection between the main base 100 and the box cover 200, ensuring the locking and sealing of the perfusion transfer box body;

[0064] Furthermore, the knob 3 is rotated 90° counterclockwise, and the long axis of the elliptical portion 31 facing the push rod 43 is converted into the short axis of the elliptical portion 31. The push rod 43 is reset under the tension of the tension spring 42, and the pressure block 51 is reset under the reaction force of the spring 54. Then, the rotating wheel 52 and the anti-slip ring 53 are disengaged from the limiting groove 7, and the main base 100 and the box cover 200 are separated, so that the infusion transfer box body is opened.

[0065] A number of bolts are provided between the upper cover 1 and the lining component 2 to achieve a fixed connection between the two.
