Description

Technical Field

[0001] The utility model belongs to the technical field of microbial culture and relates to a culture medium loader. Background Art

[0002] Microbial sample cultivation is an important task in healthcare, inspection and quarantine, disease control, and food safety. Currently, culture medium loaders are commonly used for microbial inoculation, cultivation, separation, and detection and cultivation. For example, a Chinese patent discloses a microbial culture medium device [authorization announcement number CN204474670U, wherein the culture medium comprises a box body, a box lid, a spring, a buckle, and a holder. The box body and the box lid are used in conjunction with each other and are connected by a hinge. A spring is installed at the hinged joint of the hinge connection. The spring keeps the box lid open when it is opened. The buckle has a tooth, which engages with the holder through the tooth to keep the box lid closed.

[0003] The above-mentioned device requires the box body and lid to be assembled together during production, resulting in a complex structural design, cumbersome assembly, and low assembly efficiency. During vaccination, the lid flips outward around the hinge, taking up a large amount of space. To address this problem, a split-type loader is designed with a detachable connection structure between the upper cover and the loading seat. This not only prevents the loaded items from falling, but also reduces the space occupied after the lid is opened. However, this requires using different devices to first open and then remove the lid, which increases production assembly parts and procedures, and increases costs. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems in the existing technology and to provide a culture medium loader in which the opening and removal of the cover can be operated by the same device.

[0005] The purpose of this utility model can be achieved through the following technical solutions:

[0006] The culture medium loader includes a loading seat and an upper cover, wherein the loading seat is provided with a storage cavity, and the upper cover is provided with an annular retaining edge. When the cover is closed, the annular retaining edge rests on the loading seat and is arranged around the storage cavity. The annular retaining edge has two oppositely arranged openings, and springs are provided in the openings. The loading seat is provided with two buckles arranged one-to-one corresponding to the springs, and a clamping structure is provided between the buckles and the springs for limiting the upper cover from falling off and circumferential rotation. When the springs are elastically deformed inward, the clamping structure can be disengaged.

[0007] Two springs are symmetrically arranged along the vertical centerline of the upper cover, and two latches are symmetrically arranged along the vertical centerline of the storage cavity. This locking structure not only prevents the upper cover from falling off and the contents from dropping, but also prevents the upper cover from rotating circumferentially relative to the loading base, ensuring stability. When the cover needs to be opened, the grippers of the robot simultaneously grasp the two opposing springs, causing them to elastically deform inward and disengage the latches. The robot then further transfers the upper cover. This means that both opening and removing the cover are performed by the same robot, reducing production assembly components and procedures, thereby saving costs.

[0008] A notch is formed between the spring piece and the annular retaining edge, which is beneficial to improving the elasticity of the spring piece.

[0009] In the above-mentioned culture medium loader, the snap-fit ​​structure includes a limiting boss arranged on the outside of the spring sheet, and two limiting stops extending outward are provided on the limiting boss, and a limiting opening is formed between the two limiting stops. When the cover is closed, the buckle is pressed on the limiting boss and the buckle is limited in the limiting opening.

[0010] Two stoppers, located on different sides, are symmetrically arranged along the vertical midline of the upper cover. Their width is slightly larger than the width of the buckle. By restraining the buckle through the stoppers, the upper cover can effectively limit circumferential rotation relative to the loading base. The upper surface of the stopper boss is parallel to the upper surface of the loading base. When the cover is closed, the two buckles simultaneously press against the upper surfaces of the corresponding stopper bosses, effectively preventing the upper cover from falling off.

[0011] In the above-mentioned culture medium loader, a clamping surface is provided at the outer end of the limit stop.

[0012] The gripping surfaces are vertically extending planes. When opening the cover, the robot's gripping jaws are positioned on either side of the gripping surfaces. When the gripping jaws close, the two springs elastically deform inward. The gripping surfaces increase the contact area between the gripping jaws and the cover, preventing the cover from slipping out of the gripping jaws during transfer.

[0013] In the above-mentioned culture medium loader, the clamping surfaces on different limit stops on the same side are located in the same plane, and the depth of the limit opening is greater than the length of the buckle.

[0014] The depth of the stopper extends radially along the upper cover, while the length of the buckle extends radially along the storage chamber. When opening the cover, the manipulator's gripping jaws simultaneously act on two clamping surfaces on the same side, increasing the gripper's contact area and preventing the upper cover from disengaging. Because the depth of the stopper is greater than the length of the buckle, the buckle remains out of contact with the gripper during the deformation of the spring, ensuring effective disengagement. This also allows the force exerted by the manipulator's gripping jaws on the stopper to extend radially along the upper cover, improving grip stability.

[0015] In the above-mentioned culture medium loader, the outer end of the limit stop has an extension portion extending upward, and the clamping surface is located on the extension portion.

[0016] Since the extension portion extends upward, the area of ​​the clamping surface is increased.

[0017] In the above-mentioned culture medium loader, a first guide slope is provided at the lower part of the limiting boss, and the first guide slope is inclined from inside to outside and from bottom to top; a second guide slope is provided on the buckle with the same inclination direction as the first guide slope.

[0018] When the cover is closed, the first guiding inclined surface cooperates with the second guiding inclined surface to guide the buckle, so that the buckle can pass over the limiting boss and press onto the upper surface of the limiting boss.

[0019] The buckle is L-shaped, and a mold opening is provided at the bottom of the buckle to facilitate molding.

[0020] In the above culture medium loader, the upper surface of the loading seat has at least one upwardly extending protrusion, and the protrusion has a printing area for printing an information mark barcode.

[0021] The purpose of setting the protrusion is to increase the height of the printing area, avoid the upper cover from blocking the printing, reduce the distance between the printing area and the printer, and facilitate clear printing of the printer.

[0022] In the above-mentioned culture medium loader, there are two protrusions that are arranged opposite to each other, the printing area is arranged on one of the protrusions, and the inner side of the protrusion has a matching surface that is adapted to the outer periphery of the upper cover.

[0023] Since two oppositely arranged matching surfaces are provided, the upper cover can be radially limited.

[0024] Compared with the existing technology, this culture medium loader has the following advantages: due to the provision of a snap-on structure, it can not only prevent the upper cover from falling off and the loaded items from falling, but also prevent the upper cover from rotating circumferentially relative to the loading seat, thereby ensuring stability; it is conducive to opening and closing the cover, and compared with the traditional action of opening the cover first and then moving the cover, it reduces the production assembly parts and procedures, saves costs, and ensures stability in use.

DETAILED DESCRIPTION

[0032] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0033] like Figure 1 and Figure 2 The culture medium loader shown in the figure comprises a loading seat 1 and an upper cover 2. The loading seat 1 is provided with a storage cavity 11 for storing culture dishes. Figure 1-3 As shown, the upper cover 2 is provided with an annular retaining edge 21. When the cover is closed, the annular retaining edge 21 is against the loading seat 1 and is arranged around the storage cavity 11. The annular retaining edge 21 has two oppositely arranged openings 22, and a spring piece 23 is provided in the opening 22. A gap is formed between the spring piece 23 and the annular retaining edge 21.

[0034] like Figure 1 and Figure 2 As shown, the loading seat 1 is provided with two clips 12 corresponding to the spring pieces 23, and a snap-fit ​​structure for limiting the upper cover 2 from falling off and circumferential rotation is provided between the clips 12 and the spring pieces 23. When the spring pieces 23 are elastically deformed inward, the snap-fit ​​structure can be disengaged.

[0035] The two spring pieces 23 are symmetrically arranged along the vertical center line of the upper cover 2, and the two buckles 12 are symmetrically arranged along the vertical center line of the storage cavity 11. Due to the provision of the snap-fit ​​structure, it can not only prevent the upper cover 2 from falling off and the loaded items from falling, but also prevent the upper cover 2 from rotating circumferentially relative to the loading seat 1, thereby ensuring stability.

[0036] When the cover needs to be opened, the two oppositely arranged spring pieces 23 are clamped by the clamping claws of the robot at the same time, so that the two spring pieces 23 are elastically deformed inward at the same time and disengaged from the clamping of the buckle 12. Then, the upper cover 2 is further transferred by the robot, that is, the opening and removal of the cover are both operated by the same robot, which reduces the production assembly parts and procedures and saves costs.

[0037] like Figure 4 and Figure 5 As shown, the snap-fit ​​structure includes a limiting boss 24 arranged on the outside of the spring piece 23, and two limiting stop edges 25 extending outward are provided on the limiting boss 24, and a limiting opening 26 is formed between the two limiting stop edges 25. When the cover is closed, the buckle 12 is pressed on the limiting boss 24 and the buckle 12 is limited in the limiting opening 26.

[0038] Two limiting openings 26, located on different sides, are symmetrically arranged along the vertical midline of the upper cover 2. The width of the limiting openings 26 is slightly larger than the width of the latch 12. By limiting the latch 12 through the limiting openings 26, the upper cover 2 can effectively limit the circumferential rotation relative to the loading base 1. The upper surface of the limiting boss 24 is parallel to the upper surface of the loading base 1. When the cover is closed, the two latches 12 simultaneously press against the upper surfaces of the corresponding limiting bosses 24, effectively preventing the upper cover 2 from falling off.

[0039] like Figure 5 As shown, the outer ends of the limit stop 25 are provided with clamping surfaces 27. These surfaces are vertically extending planes. When the cover is opened, the gripping jaws of the manipulator are positioned on the outer sides of the two gripping surfaces 27. When the gripping jaws close, the two springs 23 are elastically deformed inward. These gripping surfaces 27 increase the contact area between the gripping jaws and the upper cover 2, preventing the upper cover 2 from easily dislodging from the gripping jaws during transfer.

[0040] In this embodiment, the clamping surfaces 27 on different limiting stops 25 on the same side are located in the same plane, and the depth of the limiting opening 26 is greater than the length of the buckle 12 .

[0041] The depth of the stopper 26 extends radially along the upper cover 2, while the length of the buckle 12 extends radially along the storage chamber 11. When opening the cover, the manipulator's gripping jaws can simultaneously act on two clamping surfaces 27 on the same side, increasing the gripper's contact area and preventing the upper cover 2 from disengaging. Because the depth of the stopper 26 is greater than the length of the buckle 12, the buckle 12 remains out of contact with the gripper during the deformation of the spring 23, ensuring effective disengagement of the spring 23 from the buckle 12. This also allows the force exerted by the manipulator's gripping jaws on the stopper edge 25 to extend radially along the upper cover 2, improving grip stability.

[0042] like Figure 4 and Figure 5 As shown, the outer end of the limit stop 25 has an upwardly extending extension portion 28 , and the clamping surface 27 is located on the extension portion 28 , thereby increasing the area of ​​the clamping surface 27 .

[0043] like Figure 4 As shown, a first guide slope 29 is provided at the lower portion of the limiting boss 24 , and the first guide slope 29 is inclined from inside to outside and from bottom to top; a second guide slope 13 is provided on the buckle 12 in the same inclined direction as the first guide slope 29 .

[0044] When the cover is closed, the first guiding inclined surface 29 cooperates with the second guiding inclined surface 13 to guide the buckle 12 , so that the buckle 12 can pass over the limiting boss 24 and press onto the upper surface of the limiting boss 24 .

[0045] The buckle 12 is L-shaped, and for the convenience of forming, Figure 4 and Figure 6 As shown, a mold opening 2214 is provided at the lower portion of the buckle 12 .

[0046] In this embodiment, Figure 1 As shown, two upwardly extending protrusions 15 are provided on the upper surface of the loading base 1. The two protrusions 15 are arranged opposite each other, and one of the protrusions 15 has a printing area 16 for printing an information mark barcode. The purpose of providing protrusions 15 is to raise the height of the printing area 16 to prevent the upper cover 2 from blocking the printing process, and to reduce the distance between the printing area 16 and the printer, which facilitates clear printing.

[0047] The buckles 12 and the protrusions 15 are arranged alternately, that is, the buckle 12 is located in the space between the two protrusions 15 .

[0048] In order to achieve radial limitation of the upper cover 2, as shown in FIG. Figure 1 As shown, the inner side of the protrusion 15 has a matching surface 17 that matches the periphery of the upper cover 2.

[0049] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
