Description

Technical Field

[0001] This utility model belongs to the field of sample storage box technology, and specifically relates to a portable sample storage box. Background Technology

[0002] In fields such as food and environment, it is often necessary to collect both solid and liquid samples. After sampling, the samples need to be brought back to the laboratory for testing. When collecting liquid samples, test tubes are typically used for storage, and multiple sets of samples of the same sample are stored in multiple test tubes to conduct parallel tests and ensure the validity of the test results. Since sampling operations often need to be carried out in the countryside or on the client's factory premises, and multiple test tubes need to be carried for sampling and storage, sample storage boxes are often used as storage devices.

[0003] Existing sample storage boxes typically employ a side-opening or top-opening structure, with multiple support frames inside the box. Each support frame has multiple slots for securing test tubes. However, current sample storage boxes have the following problems:

[0004] 1. When carrying test tubes outside, since they are only positioned by the placement slot, they are easily dislodged from the slot due to vibration during transportation. Therefore, it is necessary to deliberately avoid shaking during carrying, which brings inconvenience to field operations.

[0005] 2. When placing / retrieving test tubes deep into the chamber through the top or side opening, the narrow operating space makes the process difficult and affects sampling efficiency. Utility Model Content

[0006] This utility model provides a portable sample storage box to solve at least one of the problems in the background art.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A portable sample storage box includes a base and a box cover. A support column is provided near the center of the upper surface of the base. Multiple sets of support components are spaced apart along the axial direction of the support column. The box cover is connected to the base by multiple quick-release fasteners. The support column and the support components are both covered inside the box cover. The support components include multiple top frames mounted on the support column and a base frame rotatably mounted on the support column and located below the top frames. The top frames are arranged radially along the circumference of the support column. Screws are threaded through the top frames at intervals. A plug is provided near the end of the screw near the base frame. The outer edge of the base frame extends radially outward along the radial direction of the support column to form an extension. The extension has multiple placement holes. By rotating the base frame, the placement holes can be rotated to align with the plugs or rotated between two adjacent top frames.

[0009] Furthermore, the plugs and placement holes within the same group are of the same size and match, while the plugs and placement holes in different groups are of different sizes.

[0010] Furthermore, the two sides of the base are connected to the two sides of the box cover by quick fasteners. The quick fasteners include a fastener seat at the bottom of the side wall of the box cover and a buckle on the side wall of the base. A buckle ring is rotatably inserted on the fastener seat and the buckle ring matches the buckle.

[0011] Furthermore, a sealing ring matching the bottom of the box cover is provided at the outer edge of the upper surface of the base.

[0012] Furthermore, the plug includes a frustum-shaped plug block and a rubber layer on the outer surface of the plug block, the plug block being connected to the screw.

[0013] Furthermore, a knob is provided on the top of the screw.

[0014] Furthermore, the base frame has a through hole in the middle for the support column to pass through. Two ball grooves are provided opposite each other on the side wall of the hole. The support column has multiple slots spaced apart along its circumference. A ball is provided in the ball groove. A spring is accommodated between the ball and the inner end wall of the ball groove. When the base frame is rotated so that the placement hole is aligned with the plug or the extension is located between two adjacent top frames, the spring pushes the ball into the slot.

[0015] Furthermore, the top of the box cover is provided with a first handle and / or the top of the support column is provided with a second handle.

[0016] Furthermore, there are four top frames and four extensions, which are equally spaced.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By setting up multi-layered shelving components, the number of test tubes that can be placed can be increased, making it suitable for carrying around. After rotating the base frame, the placement hole is moved between two adjacent top frames, making it convenient to put the test tubes into the placement hole from above.

[0019] 2. After placing the test tube, the plug can be pressed against the top of the test tube or the test tube cap by rotating the screw. This can prevent the test tube from falling off due to vibration during carrying or transportation, making it convenient to carry when going out.

[0020] 3. The box cover with a lower opening cooperates with the base. The box cover and the base are quickly connected by quick fasteners, which makes it easy to open or close the box cover quickly.

Detailed Implementation

[0028] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0029] Example 1

[0030] See Figures 1 to 5 This utility model provides a portable sample storage box, including a base 1 and a box cover 6. A support column 17 is fixedly and vertically installed on the upper surface of the base 1 near the middle. Multiple sets of shelf components are evenly spaced along the axial direction of the support column 17. The box cover 6 is connected to the base 1 by multiple quick-release fasteners. When the box cover 6 is closed on the base 1, the support column 17 and the shelf components are both covered inside the box cover 6. The shelf components include multiple top frames 16 fixed on the support column 17 and a base frame 12 rotatably sleeved on the support column 17 and located below the top frames 16. Multiple top frames 16 are arranged radially around the support column 17. Screws 10 are threaded through the top frames 16 at equal intervals. The screws 10 are threaded to the support column 17. A plug is provided at the end of the screw 10 near the base frame 12. The outer edge of the base frame 12 extends radially outward along the support column 17 to form an extension 161. Multiple placement holes 13 are provided on the extension 161. The placement holes 13 are adapted to the plugs above them. By rotating the base frame 12, the placement holes 13 can be rotated to align with the plugs or rotated between two adjacent top frames 16.

[0031] When sampling is required outside, the box cover 6 is lifted from the base 1 by opening the quick-release fasteners. Then, by rotating the base frame 12, the placement holes 13 are moved between two adjacent top frames 16. Empty test tubes 7 can be placed downwards into the placement holes 13 between the two top frames 16. This design allows for a smaller distance between the top frames 16 and the base frame 12, while also facilitating the retrieval and placement of test tubes 7, thus reducing the design height of the sample storage box. After placing the test tubes 7 into the placement holes 13, the base frame 12 is rotated so that the placement holes 13 align with the top of the box. The plug is pressed against the top of the test tube 7 by rotating the screw 10. It should be noted that most test tubes 7 used for sampling or storage will have a test tube cap 8, so the plug will press against the test tube cap 8. Of course, for some sampling with less stringent requirements, the test tube cap 8 can be omitted. In this case, the plug will directly press against the top of the test tube 7 and act as the test tube cap 8. This will fix the test tube 7 in the placement hole 13. After the box cover 6 is closed on the base 1, it is connected to the base 1 by the quick fastener.

[0032] When sampling is required, after opening the quick-release fasteners, lift the box cover 6 from the base 1, select the shelf layer where the sample needs to be stored, and rotate the screw 10 of the rotating layer to raise all the plugs, so that the base frame 12 can be rotated. Rotating the base frame 12 will move the test tube 7 between the two adjacent top frames 16 above it, making it easy to take out the test tube 7. After storing the sample in the test tube 7, put the test tube cap 8 on the test tube 7 or directly put the test tube 7 into the placement hole 13. Rotate the base frame 12 to align the test tube 7 with the plug, and rotate the screw 10 to lower the plug and press it against the test tube cap 8 or the top of the test tube 7 to complete the fixation of the test tube. When carrying is required, close the box cover 6 on the base 1 and connect it to the base 1 using the quick-release fasteners.

[0033] Specifically, the plugs and placement holes 13 within the same group are of the same size and match, while the plugs and placement holes 13 between different groups are of different sizes. This arrangement is to ensure that the test tubes 7 placed in the same layer are of the same specification and are used to sample or store the same sample, which is convenient for classified storage; while different layers can store and fix test tubes of different specifications, which can be used to sample or store different types of samples, thus improving the applicability of sample storage. It should be noted that those skilled in the art can also set the test tubes and plugs of each layer to be the same, which should also fall within the protection scope of this utility model application.

[0034] Specifically, the base 1 and the box cover 6 are connected by quick-fasteners on both sides. The quick-fasteners include a fastener 4 fixed at the bottom of the side wall of the box cover 6 and a buckle 2 fixed on the side wall of the base 1. The buckle 2 has a locking groove on its lower side. A buckle ring 3 is rotatably inserted on the fastener 4 and matches the buckle 2. When the box cover 6 is closed on the base 1, the box cover 6 can be locked on the base 1 by rotating the buckle ring 3 into the locking groove.

[0035] Specifically, the plug includes a frustoconical plug 92 and a rubber layer 91 on the outer surface of the plug 92. The plug 92 is connected to the screw 10. Through the rotational connection between the screw 10 and the top of the plug 92, when the rubber layer 91 is against the inside of the top of the test tube cap 8 or the test tube 7, the screw 10 can rotate relative to the plug 92, causing the plug to descend. This prevents the rubber layer 91 from rotating on the top of the test tube cap 8 or the test tube 7, which helps to reduce the wear of the rubber layer. The plug 92 is designed in a frustoconical shape so that when the test tube 7 is not using the test tube cap 8, the rubber layer 91 can be inserted and against the top of the test tube 7, providing a good seal. When the test tube cap 8 is used, the rubber layer 91 rests against the test tube cap 8, providing a good limiting and fixing function.

[0036] Specifically, a knob 11 is fixedly provided on the top of the screw 10, and the screw 10 can be rotated on the top frame 16 by rotating the knob 11.

[0037] Specifically, a first handle 15 is fixedly provided on the top of the box cover 6. When the box cover 6 is connected to the base 1, it is convenient to lift the box cover 6 and the base 1 for carrying. A second handle 14 is fixedly provided on the top of the support column 17, which is convenient to lift and carry the shelf component and the base 1 through the support column 17.

[0038] Specifically, there are four top frames 16 and four extensions 161, which are equally spaced. The number of holes 13 on each side of the screw 10 and extension 161 in the same group is two.

[0039] Example 2

[0040] The difference from Example 1 is as follows:

[0041] refer to Figures 1 to 5 The outer edge of the upper surface of the base 1 is provided with a sealing ring that matches the bottom of the box cover 6. The sealing ring is made of elastic material. The sealing ring is used to improve the sealing between the box cover 6 and the bottom, and its elasticity can also be used to make it easy to snap the buckle 3 into the locking groove.

[0042] Example 3

[0043] The difference from Example 1 is as follows:

[0044] refer to Figures 1 to 5The base frame 12 has a through hole in the middle for the support column 17 to pass through. Two ball grooves 19 are provided opposite each other on the side wall of the through hole. The support column 17 has eight slots 21 spaced apart around its circumference. A retaining bead 20 is provided in each ball groove 19. A spring 18 is accommodated between the retaining bead 20 and the inner end wall of the ball groove 19. When the base frame 12 is rotated so that the placement hole 13 is aligned with the plug or the extension 161 is located between two adjacent top frames 16, the spring 18 pushes the retaining bead 20 into the slot 21. The purpose of this design is that when the extension 161 is rotated between two adjacent top frames 16, the retaining bead... The spring 18 pushes the 20 into the slot 21. At this time, without a large torsional force, the base frame 12 will remain in the current position and will not rotate. This can prevent the extension 161 from rotating below the top frame 16, which would cause the top frame 16 to block the removal or insertion of the test tube 7. When the extension 161 rotates directly below the top frame 16 (when the plug is aligned with the placement hole 13), the ball 20 is locked between the ball groove 19 and the slot 21. This can prevent the base frame 12 from rotating when the screw 10 is turned, thus preventing the plug from accurately pressing against the top of the test tube 7, and making the locking operation convenient.

[0045] Additionally, it should be noted that bearings are provided on both the upper and lower sides of the ball groove 19, and the bearings are used to connect the support column 17 and the base frame 12.

[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
