Description

Technical Field

[0001] This utility model relates to the field of liquid chromatography column storage, and more specifically to a liquid chromatography column storage box. Background Technology

[0002] In existing technologies, liquid chromatography is widely used in pharmaceutical research and development and product testing. The demand for liquid chromatography columns is increasing in laboratories of various R&D and manufacturing companies. From the early stage of method development, screening of different quality standards, method optimization, to the mid-to-late stage of durability and stability testing under different conditions, there is a huge demand for chromatography columns. When the chromatography column is not in use for a period of time, it needs to be stored for a long time. However, the size of liquid chromatography columns is such that even with the same diameter, there are different lengths.

[0003] Existing storage boxes typically have a fixed depth for the storage compartments, making it impossible to adjust for different lengths of liquid chromatography columns. For example, when storing shorter columns, an excessively deep compartment wastes space; while with longer columns, the compartment may not fit completely or may become unstable after placement.

[0004] Therefore, how to provide a new liquid chromatography column storage box, in which the depth of each storage tank can be adaptively adjusted according to the length of the liquid chromatography column, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a liquid chromatography column storage box, which aims to solve the technical problem that the storage tank depth of the above-mentioned traditional storage boxes is fixed and cannot be adaptively adjusted according to liquid chromatography columns of different lengths.

[0006] A liquid chromatography column storage box, comprising:

[0007] The box body includes a main body with an opening at the top and a top cover that fits over the opening of the main body.

[0008] The storage component includes a storage block, a support disk, and a limiting component. The storage block is slidably connected to the inner wall of the main body along the height direction of the main body. A storage slot is formed at the top of the storage block, and an elongated hole penetrating the storage slot is formed on the side wall of the storage block. A limiting slot is formed on the side wall of the storage block with the elongated hole, penetrating the inner wall of the elongated hole. The number of limiting slots is multiple and arranged in an array along the length direction of the elongated hole. The support disk is located inside the storage slot. The limiting component includes a rotating shaft and a limiting block. The rotating shaft is fastened to the cylindrical surface of the support disk. The limiting block is fixedly connected to the cylindrical surface of the rotating shaft and rotatably connected to the limiting slot. The limiting block is arranged at an angle to the axis of the support disk. The maximum width of the limiting block along the circumference of the rotating shaft is less than the width of the elongated hole.

[0009] Through the above technical solution, this utility model limits the maximum width of the limiting block along the circumference of the rotating shaft to be less than the width of the elongated hole, so that the limiting block can slide along the length direction of the elongated hole after rotating into it. The limiting block is fixedly connected to the side wall of the rotating shaft and rotatably connected to the limiting groove, so that the support plate can only rotate at the limiting groove. After the upper plate surface of the support plate contacts and abuts against the bottom end of the liquid chromatography column, under the pressure of the liquid chromatography column, the plate surface of the support plate is perpendicular to the opening direction of the storage tank. Because the limiting block and the axis of the support plate are arranged at an angle, the limiting block is located in the limiting groove while the plate surface of the support plate is perpendicular to the opening direction of the storage tank, thereby locking the position of the support plate. It has the characteristics of adjustable depth and automatic locking of the limiting block after the liquid chromatography column is placed.

[0010] Preferably, there are two limiting blocks and two limiting grooves, which are arranged symmetrically about the axis of rotation. The limiting grooves are arranged perpendicular to the height direction of the main body along the circumferential side wall of the rotating shaft.

[0011] Preferably, the box has a front end and a rear end arranged opposite to each other, the storage slot is a cylindrical slot, the number of limiting components is two sets, and they are arranged symmetrically about the center of the support plate. The elongated hole is arranged opposite to the axis of the storage slot and penetrates the front and rear walls of the storage block. Limiting slots are opened on both the front and rear walls of the storage block.

[0012] Preferably, two limiting grooves symmetrically arranged about the axis of the rotating shaft constitute a limiting groove group, and multiple limiting groove groups are arranged in an array along the length direction of the elongated hole.

[0013] Preferably, it also includes a knob, which is coaxially arranged with the rotating shaft and fixedly connected to the rotating shaft.

[0014] Preferably, it also includes a protective pad, which is fixedly connected to the side wall of the storage tank.

[0015] Preferably, it also includes a handle, which is fixedly connected to the upper surface of the storage block.

[0016] Preferably, it also includes a second protective pad, which is fixedly connected to the upper surface of the support plate.

[0017] Preferably, it also includes a slide rail and a slider, the slide rail being fixedly connected to the side wall of the storage block, the slider being fixedly connected to the inner side wall of the main body, and the slide rail and the slider being slidably connected.

[0018] Preferably, there are two sets of slide rails and sliders, arranged symmetrically on the side of the storage block.

[0019] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a liquid chromatography column storage box with the following beneficial effects: by setting a storage block, a support plate, and a limiting component, the depth of the storage tank is adjustable. The storage block is slidably connected to the main body, and the limiting block cooperates with the limiting groove. Rotating the limiting block into the limiting groove fixes the position of the support plate, thereby fixing the depth of the storage tank. In this way, the depth of the storage tank can be adjusted according to liquid chromatography columns of different lengths, avoiding space waste and preventing shorter columns from being unstable when placed inside, thus improving the versatility and practicality of the storage box.

Detailed Implementation

[0031] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0032] See appendix Figures 1-10 This utility model discloses a liquid chromatography column storage box, including: a box body and a storage component 2;

[0033] The box includes a main body 1 with an opening at the top and a top cover 3 that covers the opening of the main body 1. The main body 1 has a front end and a rear end that are arranged opposite to each other.

[0034] Storage component 2 includes storage block 21, support disk 22, and limiting component 23. Storage block 21 is slidably connected to the inner wall of main body 1 along the height direction of main body 1. Storage slot 211 is formed at the top of storage block 21, and elongated hole 212 penetrating storage slot 212 is formed on the wall of storage block 21. Limiting slot 213 penetrating the inner wall of elongated hole 212 is formed on the side wall of storage block 21 with elongated hole 212. The number of limiting slots 213 is multiple and extends along the elongated hole. The holes 212 are arranged in an array along their length. The support plate 22 is located inside the storage slot 211. The limiting component 23 includes a rotating shaft 231 and a limiting block 232. The rotating shaft 231 is fastened to the cylindrical surface of the support plate 22. The limiting block 232 is fixedly connected to the cylindrical surface of the rotating shaft 231 and rotatably connected to the limiting slot 213. The limiting block 232 is arranged at an angle to the axis of the support plate 22. The maximum width of the limiting block 232 along the circumference of the rotating shaft 231 is less than the width of the elongated hole 212.

[0035] Specifically, the top cover 3 is hinged to the body 1 at the edge of its opening end.

[0036] Specifically, the lower end face of the top cover 3 is provided with an installation groove, and a buffer pad 9 is installed in the installation groove to buffer and protect the top of the liquid chromatography column.

[0037] More specifically, a buffer platform 91 is fixedly connected to the position of the buffer pad 9 corresponding to the storage tank 211, which is used to provide a certain preset pressure to the top of the liquid chromatography column located in the storage tank 211, so that it is more stable in the storage tank 211.

[0038] Specifically, there are multiple storage components 2, which are arranged in an array along the front and back direction of the main body 1.

[0039] More specifically, the number of storage components 2 is 5.

[0040] In some embodiments, there are two limiting blocks 232 and two limiting grooves 213, which are arranged symmetrically about the axis of the rotating shaft 231. The limiting grooves 213 are arranged perpendicularly to the height direction of the main body 1 along the circumferential sidewall of the rotating shaft 231. This makes the rotation of the rotating shaft 231 more stable.

[0041] Specifically, the limiting block 232 is fan-shaped and coaxially arranged with the rotating shaft 231. The limiting groove 213 is arranged correspondingly to the limiting block 232. The arc surface of the limiting block 232 is slidably connected to the arc side wall of the limiting groove 213. When the limiting block 232 and the opposite side wall of the limiting groove 213 come into contact, the axis of the support plate 22 is parallel to the height direction of the main body 1.

[0042] In other embodiments, the housing has a front end and a rear end arranged opposite to each other, the storage slot 211 is a cylindrical slot, the number of limiting components 23 is two sets, and they are arranged symmetrically about the center of the support plate 22. The elongated hole 212 is arranged opposite to the axis of the storage slot 211 and penetrates the front and rear walls of the storage block 21. Limiting slots 213 are provided on both the front and rear walls of the storage block 21. Thus, the provision of limiting slots 213 and the arrangement of limiting components 23 on both the front and rear walls of the storage block 21 further enhance the rotational stability of the rotating shaft 231.

[0043] In one embodiment, two limiting grooves 213 arranged symmetrically about the axis of the rotating shaft 231 constitute a limiting groove group, and multiple limiting groove groups are arranged in an array along the length direction of the elongated hole 212.

[0044] In one embodiment, a knob 230 is also included, which is coaxially arranged with and fixedly connected to the rotating shaft 231. Thus, by providing a knob 230 and a fixed connection to the rotating shaft 231, it is convenient for the operator to rotate the rotating shaft 231, thereby adjusting the position of the support plate 22 more easily and conveniently, and thus quickly adjusting the depth of the storage slot 211.

[0045] In some embodiments, a protective pad 4 is also included, which is fixedly connected to the side wall of the storage slot 211.

[0046] In some embodiments, a handle 5 is also included, which is fixedly connected to the upper surface of the storage block 21.

[0047] Specifically, there are two handles 5, which are arranged symmetrically along the center of the top of the storage block 21.

[0048] In this embodiment, a second protective pad 6 is also included, which is fixedly connected to the upper surface of the support disk 22. Thus, the fixed connection between the second protective pad 6 and the upper surface of the support disk 22 protects the bottom of the liquid chromatography column, preventing it from directly contacting the support disk 22 and causing wear or damage.

[0049] In some specific embodiments, a slide rail 7 and a slider 8 are also included. The slide rail 7 is fixedly connected to the side wall of the storage block 21, and the slider 8 is fixedly connected to the inner side wall of the main body 1. The slide rail 7 and the slider 8 are slidably connected. Thus, the arrangement of the slide rail 7 and the slider 8 makes the sliding between the storage block 21 and the main body 1 smoother and more stable.

[0050] In other specific embodiments, there are two sets of slide rails 7 and sliders 8, arranged symmetrically on the side of the storage block 21. Therefore, having two sets of slide rails 7 and sliders 8 arranged symmetrically further improves the stability and reliability of the sliding of the storage block 21, making the force on the storage block 21 more uniform during sliding and avoiding problems such as tilting and jamming that may occur during sliding.

[0051] Specifically, it also includes a latch, which is used to lock the front ends of the main body 1 and the top cover 3.

[0052] The specific principle and usage of the liquid chromatography column storage box provided in this embodiment are as follows:

[0053] When placing a liquid chromatography column, first open the top cover, hold handle 5 and lift the storage block 21 out of the main body 1. According to the length of the liquid chromatography column, manually rotate the knob 230 so that the limiting block 232 rotates out of the limiting groove 213 and into the elongated hole 212. Since the width of the limiting block 232 is smaller than the width of the elongated hole 212, the support plate 22 can be adjusted up and down along the length of the elongated hole 212. After adjusting the support plate 22 to a suitable height, screw the limiting block 232 into the limiting groove 213 to lock the position of the support plate 22 along the length of the elongated hole 212. After placing the liquid chromatography column in the storage tank 211, the support plate 22 remains horizontal under the pressure of the liquid chromatography column and the axial restriction of the liquid chromatography column by the inner wall of the storage tank 211, locking the rotation of the rotating shaft 231. It has the characteristics of adjustable depth and automatic locking of the limiting position after the liquid chromatography column is placed.

[0054] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
