Description

Technical Field

[0001] The utility model relates to the technical field of sample storage, and particularly discloses a sample storage device. Background Art

[0002] Environmental protection is increasingly valued in modern society. Environmental monitoring is the process of monitoring and measuring indicators that reflect environmental quality to determine the status of environmental pollution and the level of environmental quality. The main monitoring media include water quality monitoring, air testing, soil monitoring, etc.

[0003] The sample storage device for environmental testing is an indispensable equipment in environmental monitoring work. It is mainly used to store and protect the collected environmental samples to ensure the integrity and accuracy of the samples.

[0004] The existing sample storage device collects samples into sample tubes, and then stores the sample tubes in the sample storage device for storage. Since the sample storage device lacks a clamping function for the sample tubes, this may cause the sample storage device to be bumpy during transportation, causing the sample tubes to break. In addition, due to the different heights of the existing sample tubes, it is not very convenient to put them in and out of the device. Utility Model Content

[0005] In order to solve the above problems, the present invention discloses a sample storage device, which is implemented through the following technical solutions.

[0006] A sample storage device comprises a box body, an inner lining block, a lifting base plate, a screw and a clamping plate, the top of the box body is rotatably connected to a box cover, the bottom center of the box body is rotatably connected to a screw, the top of the screw is fixedly connected to a disc, the top of the disc is fixedly connected to a rocker, the bottom of the box body is symmetrically fixed to a guide rod, the screw is meshed with a lifting base plate, the lifting base plate is slidably connected to the guide rod, the top of the guide rod is fixedly connected to the inner lining block, a plurality of placement holes are opened on the inner lining block, a plurality of springs are evenly fixed to the inner wall circumference of the placement hole, and the clamping plate is fixed to the inner lining block through the spring.

[0018] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figure 1-4 As shown, the utility model provides a technical solution: a sample storage device, comprising a box body 1, an inner lining block 2, a lifting base plate 3, a screw rod 4 and a clamping plate 5, the top of the box body 1 is rotatably connected to a box cover 11, the bottom center of the box body 1 is rotatably connected to a screw rod 4, the top of the screw rod 4 is fixedly connected to a disc 41, the top of the disc 41 is fixedly connected to a rocker arm 42, the bottom of the box body 1 is symmetrically fixed to a guide rod 12, the lifting base plate 3 is engaged with the screw rod 4, the lifting base plate 3 is slidably connected to the guide rod 12, the top of the guide rod 12 is fixedly connected to the inner lining block 2, a plurality of placement holes 21 are opened on the inner lining block 2, a plurality of springs 22 are evenly fixed to the inner wall circumference of the placement hole 21, and the clamping plate 5 is fixed to the inner lining block 2 through the spring 22.

[0020] Preferably, a sealing gasket 13 is fixed to the bottom of the box cover 11 , and a fixing hole 14 corresponding to the disc 41 is opened on the sealing gasket 13 , and the size of the sealing gasket 13 matches the caliber of the box body 1 .

[0021] The sealing gasket 13 at the bottom of the box cover 11 fits in with the liner block 2 , which can fix the sample tube and prevent it from shaking up and down.

[0022] Preferably, a first magnetic strip 15 is fixedly connected to the bottom of the box cover 11 in a bilaterally symmetrical manner, and a second magnetic strip corresponding to the first magnetic strip 15 is fixedly connected to the top of the box body 1. The first magnetic strip 15 and the second magnetic strip 16 are magnetically attracted to each other.

[0023] When the box cover 11 is engaged with the box body 1 , the mutual magnetic attraction between the first magnetic strip 15 and the second magnetic strip 16 can maintain the stability of the interior of the box body 1 , thereby better protecting the storage of samples.

[0024] Preferably, a cylinder 31 corresponding to the placement hole 21 is fixedly connected to the lifting base plate 3 , and the diameter of the cylinder 31 is smaller than the aperture of the placement hole 21 .

[0025] By fixing a cylinder 31 having a diameter smaller than the placement hole 21 on the lifting base plate 3, when a sample tube is too low, the sample tube can be conveniently taken out by controlling the height of the lifting base plate 3. When a sample tube is too high, the sample tube can be easily stored by controlling the height of the lifting base plate 3.

[0026] Preferably, connecting shafts 17 are symmetrically fixed to the left and right sides of the box body 1 , and a handle 18 is rotatably connected to the connecting shaft 17 .

[0027] By providing a handle 18 on the box body 1, it is possible for staff to use the device more conveniently.

[0028] A specific embodiment of the present invention is as follows:

[0029] When the sample is stored, the staff puts the sample tube filled with the sample into the placement hole 21 on the inner lining block 2. During the placement process, the clamping plate 5 fixed with the spring 22 on the inner wall of the placement hole 21 will clamp the sample tube, avoiding the possibility of the sample tube being shaken during transportation and causing spillage or breakage. When encountering sample tubes of different heights, it is easier to store the sample tube in the placement hole 21 for the sample tube of lower height. When facing the sample tube of higher height, the storage of the sample tube will cause the sample tube to be too high and the box plate cannot be covered. At this time, the rocker 42 can be rotated to drive the screw 4 to rotate. Under the action of the guide rod 12, the lifting bottom plate 3 will fall downward, and the staff will be able to store the sample tube more easily. After storing the sample tube, the box cover 11 is closed. With the cooperation of the first magnetic strip 15 and the second magnetic strip 16, the box cover 11 and the box body 1 are integrated. The handle 18 is rotated to a vertical state, which can be more convenient to carry and store the device. When taking out the sample tube, it is difficult to take out the sample tube that is relatively low because the top of the tube is located in the placement hole 21. At this time, the rocker 42 can be rotated to drive the screw 4 to rotate. Under the action of the guide rod 12, the lifting base 3 will rise upward, squeezing the lower sample tube out of the placement hole 21, so that the staff can take out the sample tube more easily.

[0030] The preferred embodiments of the present invention disclosed above are intended only to help illustrate the present invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the present invention to specific embodiments. Obviously, numerous modifications and variations are possible based on the contents of this specification. These embodiments are selected and described in detail in this specification to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention. The present invention is limited only by the claims and their full scope and equivalents.
