Abstract
Description
Technical Field
[0001] The utility model relates to a loading tool, in particular to a catalyst box and a soft film isolation bin. Background Art
[0002] Microorganisms need a specific growth environment during the experiment, so they need to be placed in a soft film isolation chamber to facilitate the control of their growth environment; when microorganisms need to grow in an anaerobic environment, catalysts are needed to accelerate the consumption of oxygen in the chamber, and catalysts as consumables need to be replaced frequently, so catalysts are usually placed in a loading tool that is detachable from the soft film isolation chamber, usually a drawer. Conventional drawers require a large installation space and are difficult to adapt to the working environment of the soft film isolation chamber when the soft film isolation chamber is in a relatively narrow environment.
[0003] There is also a foldable storage box in the prior art, such as the Chinese patent with announcement number CN216135457U, which includes a box body and a pull-out box movably installed in the box body; the box body is provided with a pull-out opening, and the pull-out box is movably installed in the pull-out opening; the bottom plate of the box body is provided with an opening for cooperating with the pull-out box to fold.
[0004] Although the foldable storage box disclosed in the above patent can be folded relative to the box body on which it is installed, the storage box is still an integral unit and cannot be completely pulled out in a narrow environment. At the same time, if such a storage box structure is used to store catalyst, it is obvious that leakage will occur and it will be difficult to clean. Utility Model Content
[0005] In order to solve the problems existing in the prior art, the utility model discloses a catalyst box.
[0006] A catalyst box comprises a handle and a box body, wherein the box body comprises a plurality of accommodating chambers which are rotatably connected in sequence, and each accommodating chamber is provided with a plurality of through holes;
[0007] The handle is movably connected to a storage bin located at the edge of the box body, and the opening direction of the storage bin farthest from the handle faces the handle; it also includes a bin cover corresponding to the opening of the storage bin one by one, and the bin cover is detachably connected to the corresponding opening.
[0008] Specifically, the storage bin is filled with a catalyst, and the structure of the bin cover can prevent the catalyst from leaking out of the storage bin. The structure of the handle facilitates the pulling and drawing of the catalyst box. At the same time, air enters the storage bin from the through hole to react with the catalyst (consuming unnecessary gas). When the catalyst box is used, it is necessary to place the catalyst box in the cavity. The catalyst box is arranged into a structure of multiple storage bins connected in sequence and rotated to realize the foldable function of the catalyst box. Under this structure, even if the depth of the catalyst box is deep, when the catalyst box is pulled out of the cavity, there is no need to set up a large space. It is only necessary to ensure that a single storage bin can be completely pulled out of the cavity to complete the replacement of the catalyst.
[0009] In addition, since the opening direction of the storage chamber farthest from the handle is toward the handle, when replacing the catalyst in the storage chamber farthest from the handle, the catalyst can be replaced without completely pulling out the storage chamber. This structure facilitates the pulling and pulling of the catalyst box in the cavity and effectively shortens the installation time.
[0010] Preferably, it further comprises a plurality of first hinges for movably connecting two adjacent storage bins, and the two hinge pieces of each of the first hinges are respectively fixed on the bottom plates of the two adjacent storage bins.
[0011] Specifically, the first hinge connection structure is adopted between adjacent storage bins, which can ensure that there is a larger rotation angle between adjacent storage bins and an obvious gap between adjacent storage bins, thereby ensuring that there will be no interference after the bin covers are set at the bin openings.
[0012] Preferably, it further comprises a second hinge, and the handle is movably connected to a storage bin located at the edge via the second hinge; and a convex strip for easy gripping is provided at one end of the handle away from the storage bin.
[0013] Specifically, the handle is provided with a convex strip structure, which is convenient for the operator to grasp on the one hand, and convenient for the operator to apply pulling force and pushing force to the handle on the other hand, thereby making the catalyst box more convenient to move in the cavity.
[0014] A soft membrane isolation chamber includes a catalyst module, using a catalyst box as described in any of the above items, the catalyst module includes a cavity for accommodating the catalyst box and having an opening on the side, a limit plate is provided in the cavity, and the limit plate is used to limit the depth to which the catalyst box can be pushed into the cavity.
[0015] Specifically, when the catalyst box is placed in the cavity of the catalyst module of the soft membrane isolation chamber, the relative stability of its position needs to be ensured. The relative stability includes the ability to accurately push the catalyst box back to its original position after each catalyst replacement. The utility model provides a limit plate structure. After each catalyst replacement, the catalyst box only needs to be pushed until it hits the limit plate to ensure that the catalyst box is pushed back to its original position.
[0016] Preferably, a positioning device is further provided in the cavity, and the positioning device is used to limit the position of the handle in the cavity.
[0017] Specifically, the relative stability of the position of the catalyst box in the cavity of the catalyst module also includes ensuring that the position of the catalyst box remains unchanged during use. Therefore, a positioning device is provided to limit the position of the handle in the cavity, and the handle is connected to each containing chamber. Therefore, after the position of the handle is limited, the position of each containing chamber is also limited.
[0018] Preferably, the positioning device is a screw detachably connected to the bottom plate of the cavity, and the handle and the bottom plate of the cavity are both provided with positioning holes adapted to the screw.
[0019] Specifically, during use, the catalyst box containing the catalyst is first pushed into the cavity until it hits the limit plate. At this time, the positioning hole of the handle is matched with the positioning hole of the bottom plate of the cavity, and the handle is positioned with screws; when the catalyst box needs to be pulled out of the cavity, the screws are first removed, and then the catalyst box can be pulled out.
[0020] Preferably, the limiting plates are two L-shaped plates arranged opposite to each other, the placement direction of the longer sections of the two L-shaped plates is parallel to the pulling direction of the catalyst box, and the shorter sections of the two L-shaped plates are arranged facing each other.
[0021] Specifically, under this structure, the shorter end of the L-shaped plate is used to abut against the catalyst box, and the longer end of the L-shaped plate is used to guide the pulling out of the catalyst box. The structure in which the two L-shaped plates are relatively arranged can further limit the position of the catalyst box. Combined with the structure of the positioning device, the catalyst box can be effectively placed in the cavity to prevent displacement in any direction.
[0022] Preferably, the catalyst module further comprises a cover plate, and the cover plate is detachably and sealingly connected to the opening of the cavity.
[0023] Specifically, the soft film isolation chamber needs to be isolated from the external environment during use, so it is appropriate to provide a cover plate that is detachably and hermetically connected to the opening of the cavity.
[0024] Preferably, it also includes a blower, and the blower is used to blow gas into the catalyst box.
[0025] Compared with the prior art, the utility model is beneficial in that:
[0026] The catalyst box is arranged to be a plurality of receiving chambers connected in rotation in sequence, so that the catalyst box can be folded, thereby realizing the small space installation of the catalyst box; the opening direction of the receiving chamber farthest from the handle is toward the handle, and when replacing the catalyst in the receiving chamber farthest from the handle, the catalyst can be replaced without completely pulling out the receiving chamber, and the structure of the limit plate is provided, so that the catalyst box can be installed in place at one time without multiple adjustments. This structure facilitates the pulling and drawing of the catalyst box in the cavity, and effectively shortens the installation time. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0032] like Figure 1 As shown, a catalyst box includes a handle 10 and a box body, the box body includes a plurality of accommodating chambers 20 that are rotatably connected in sequence, and each accommodating chamber 20 is provided with a plurality of through holes 21;
[0033] The handle 10 is movably connected to a storage bin 20 located at the edge of the box body, and the opening direction of the storage bin 20 farthest from the handle 10 is toward the handle 10; it also includes a bin cover 22 corresponding to the openings of the storage bin 20 one by one, and the bin cover 22 is detachably connected to the corresponding opening.
[0034] The storage bin 20 is filled with a catalyst, and the structure of the bin cover 22 can prevent the catalyst from leaking out of the storage bin 20. The structure of the handle 10 facilitates the pulling and drawing of the catalyst box. At the same time, air enters the storage bin 20 from the through hole 21 to react with the catalyst (consume unnecessary gas). When the catalyst box is used, it is necessary to place the catalyst box in the cavity. The catalyst box is arranged into a structure of multiple storage bins 20 connected in rotation in sequence to realize the foldable function of the catalyst box. Under this structure, even if the depth of the catalyst box is deep, when the catalyst box is pulled out of the cavity, there is no need to set up a large space. It is only necessary to ensure that a single storage bin 20 can be completely pulled out of the cavity to complete the replacement of the catalyst.
[0035] In addition, since the opening direction of the storage chamber 20 farthest from the handle 10 is toward the handle 10, when replacing the catalyst in the storage chamber 20 farthest from the handle 10, the catalyst can be replaced without completely pulling out the storage chamber 20. This structure facilitates the pulling and pulling of the catalyst box in the cavity and effectively shortens the installation time.
[0036] It also includes a plurality of first hinges 30 for movably connecting two adjacent storage bins 20 , and two hinge pieces of each first hinge 30 are respectively fixed on the bottom plates of the two adjacent storage bins 20 .
[0037] The structure in which adjacent storage bins 20 are connected by the first hinge 30 can ensure that there is a larger rotation angle between adjacent storage bins 20 and an obvious gap between adjacent storage bins 20, thereby ensuring that there will be no interference after the bin cover 22 is set at the bin opening of the storage bin 20.
[0038] It also includes a second hinge 40, through which the handle 10 is movably connected to a receiving compartment 20 located at the edge; a convex strip 11 for easy gripping is provided at one end of the handle 10 away from the receiving compartment 20.
[0039] The structure of the convex strip 11 provided on the handle 10 facilitates the operator's grip on the one hand, and facilitates the operator to apply pulling force and pushing force to the handle 10 on the other hand, thereby making it more convenient for the catalyst box to move in the cavity.
[0040] like Figure 2-4 As shown, the soft membrane isolation chamber includes a catalyst module 50, which adopts the aforementioned catalyst box. The catalyst module 50 includes a cavity 51 for accommodating the catalyst box and having an opening on the side. A limiting plate 52 is provided in the cavity 51, and the limiting plate 52 is used to limit the depth to which the catalyst box can be pushed into the cavity 51.
[0041] When the catalyst box is placed in the cavity 51 of the catalyst module 50 of the soft membrane isolation chamber, the relative stability of its position needs to be ensured. The relative stability includes being able to accurately push the catalyst box back to its original position after each catalyst replacement. The present embodiment provides a structure of a limiting plate 52. After each catalyst replacement, the catalyst box only needs to be pushed until it hits the limiting plate 52 to ensure that the catalyst box is pushed back to its original position.
[0042] A positioning device 53 is also provided in the cavity 51 , and the positioning device 53 is used to limit the position of the handle 10 in the cavity 51 .
[0043] The relative stability of the position of the catalyst box in the cavity 51 of the catalyst module 50 also includes ensuring that the position of the catalyst box remains unchanged during use. Therefore, a positioning device 53 is provided to limit the position of the handle 10 in the cavity 51, and the handle 10 is connected to each containing chamber 20. Therefore, after the position of the handle 10 is limited, the position of each containing chamber 20 is also limited.
[0044] The positioning device 53 is a screw detachably connected to the bottom plate of the cavity 51 , and the handle 10 and the bottom plate of the cavity 51 are both provided with positioning holes adapted to the screw.
[0045] During use, the catalyst box containing the catalyst is first pushed into the cavity 51 until it hits the limit plate 52. At this time, the positioning hole of the handle 10 is matched with the positioning hole position of the bottom plate of the cavity 51, and the handle 10 is positioned with screws; when the catalyst box needs to be pulled out of the cavity 51, the screws are first removed, and then the catalyst box can be pulled out.
[0046] The limiting plates 52 are two L-shaped plates arranged opposite to each other. The placement direction of the longer sections of the two L-shaped plates is parallel to the pulling direction of the catalyst box, and the shorter sections of the two L-shaped plates are arranged to face each other.
[0047] In this structure, the shorter end of the L-shaped plate is used to abut against the catalyst box, and the longer end of the L-shaped plate is used to guide the pulling out of the catalyst box. The structure of the two L-shaped plates arranged relatively to each other can further limit the position of the catalyst box. Combined with the structure of the positioning device 53, the catalyst box can be effectively placed in the cavity 51 to avoid displacement in any direction.
[0048] The catalyst module 50 further includes a cover plate 60 , which is detachably and hermetically connected to the opening of the cavity 51 .
