Description

Technical Field

[0001] The utility model relates to the technical field of sample preservation, in particular to a device for preserving wastewater detection samples. Background Technique

[0002] Wastewater detection is the process of detecting the concentration of pollutants in wastewater and provides an important basis for sewage treatment and water quality management. During the process of wastewater detection, containers are needed to collect the wastewater, and multiple bottles of containers filled with wastewater are placed in a storage box. The storage box can store the wastewater detection samples. However, there are still certain defects in the existing sample preservation devices when in use.

[0003] In the prior art, the overall structure of the sample preservation device is relatively simple. Multiple groups of sample containers can be placed inside it. Usually, the sample preservation device is transported by a vehicle. During the driving of the vehicle, it is inevitable that there will be bumps, which may cause the sample containers inside the sample preservation device to shake and collide easily, making the sample containers prone to damage. Content of the Utility Model

[0004] The purpose of the utility model is to provide a device for preserving wastewater detection samples to solve the problem that the sample containers inside the existing sample preservation devices on the market are prone to shake and collide as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A device for preserving wastewater detection samples, comprising: a box body, a box cover, a placement seat and sample containers. The top of the box body is connected with the box cover through a hinge. A placement seat is installed inside the box body, and sample containers are placed inside the placement seat.

[0006] Preferably, a sealing foam is bonded to the inner wall of the box cover. A connecting block is connected to the top of the box cover. A lead screw is connected inside the connecting block through a bearing. A moving block is threadedly connected to the outside of the lead screw. Pressure plates are connected to both sides of the moving block.

[0007] Preferably, a sliding rod is connected to the bottom of the pressure plate. The ends of the two sliding rods are commonly connected to a cross plate. A limiting seat is installed at the bottom of the cross plate. A rubber plate is bonded to the inner wall of the limiting seat. Rubber protrusions are bonded to the inner wall of the placement seat.

[0008] Preferably, a sliding structure is formed between the sliding rod and the box cover. The inner wall size of the limiting seat matches the end size of the sample container.

[0009] Preferably, fixing blocks are welded to both sides of the box body. A sliding column is slidably connected inside the fixing block. A card slot is opened inside the sliding column.

[0010] Preferably, the ends of the two sliding columns are jointly connected with a cross bar, the outer sides of the two fixed blocks are jointly welded with a mounting block, and a latch is slidably connected inside the mounting block and the fixed block.

[0011] Preferably, a spring is connected between the latch and the mounting block, and the ends of the two latches are jointly connected with a connecting plate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: for this wastewater detection sample preservation device, when all the sample containers are placed inside the placement seat, the rubber protrusions can assist in limiting the sample containers. When the lead screw rotates, it can drive the moving block to perform threaded sliding. When the moving block performs threaded sliding, it can drive the two groups of pressing plates to move towards the direction of the box cover. When both groups of cross bars move to the specified height, at this time, two people can respectively hold the two groups of cross bars to lift the box body, thereby carrying the box body. The box body can be simply and conveniently carried through the two groups of cross bars, and the two people can apply force better during the carrying process.

[0013] 1. The sample preservation device can accommodate and place the sample containers. When the box body shakes due to external factors, it is easy to cause the sample containers to shake and collide, making the sample containers easily damaged. When all the sample containers are placed inside the placement seat, the rubber protrusions can assist in limiting the sample containers. When the lead screw rotates, it can drive the moving block to perform threaded sliding. When the moving block performs threaded sliding, it can drive the two groups of pressing plates to move towards the direction of the box cover. When the sliding rod slides, it can drive the cross plate and the limit seat to move towards the end of the sample container. When the bottom of the pressing plate moves to the surface of the box cover, the limit seat can move to the end of the sample container. At this time, the end of the sample container is located inside the limit seat, and the rubber plate will be pressed against the surface of the end of the sample container, so that the limit seat can stably limit the sample container. When the box body shakes, the limit seat and the rubber protrusions can limit the sample container, making the sample container not easy to shake and collide.

[0014] 2. The overall weight of the sample preservation device and the sample containers placed inside it is relatively heavy, and two people are required to carry it together. Since there is usually only one handle on the box cover, it is difficult for the two people to lift the box body during the carrying process. When the connecting plate moves, it can drive the latch to move. When the latch moves, it can squeeze the spring. When the end of the latch slides out of a group of card slots, it can pull the cross bar. When the connecting plate is released, the latch can be reset by the spring. When the latch is reset, its end can be inserted into another group of card slots. At this time, the latch can limit the sliding column. When both groups of cross bars move to the specified height, at this time, two people can respectively hold the two groups of cross bars to lift the box body, thereby carrying the box body. The box body can be simply and conveniently carried through the two groups of cross bars, and the two people can apply force better during the carrying process. Description of the Drawings

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figure 1 and Figure 2 It can be seen that the present utility model provides a technical solution: a waste water detection sample preservation device, including: box body 1, box cover 2, placing seat 3 and sample container 4. The top of the box body 1 is connected with the box cover 2 through a hinge. A placing seat 3 is installed inside the box body 1, and a sample container 4 is placed inside the placing seat 3. A sealing foam 5 is bonded to the inner wall of the box cover 2. A connecting block 6 is connected to the top of the box cover 2. A lead screw 7 is connected to the inside of the connecting block 6 through a bearing. A moving block 8 is threadedly connected to the outside of the lead screw 7. Pressing plates 9 are connected to both sides of the moving block 8. A sliding rod 10 is connected to the bottom of the pressing plate 9. Cross plates 11 are commonly connected to the ends of the two sliding rods 10. A limiting seat 12 is installed at the bottom of the cross plate 11. A rubber plate 13 is bonded to the inner wall of the limiting seat 12. A rubber protrusion 14 is bonded to the inner wall of the placing seat 3. The sliding rod 10 and the box cover 2 form a sliding structure. The inner wall size of the limiting seat 12 matches the end size of the sample container 4.

[0021] During specific implementation, the sample storage device can accommodate and arrange the sample container 4. When the box body 1 shakes due to external factors, it is easy to cause the sample container 4 to shake and collide, making the sample container 4 prone to damage. When all the sample containers 4 are placed inside the placement seat 3, the rubber protrusions 14 will undergo compressive deformation. The rubber protrusions 14 can assist in limiting the position of the sample container 4 and close the box cover 2. At this time, the lead screw 7 can be rotated forward. When the lead screw 7 rotates, it can drive the moving block 8 to perform threaded sliding. When the moving block 8 performs threaded sliding, it can drive two groups of pressing plates 9 to move towards the box cover 2. When the pressing plates 9 move, they can drive the sliding rods 10 to move. When the sliding rods 10 move, they can slide through the box cover 2 and the sealing foam 5. When the sliding rods 10 slide, they can drive the cross plate 11 and the limiting seat 12 to move towards the end of the sample container 4. When the bottom of the pressing plate 9 moves to the surface of the box cover 2, the limiting seat 12 can move to the end of the sample container 4. At this time, the end of the sample container 4 is located inside the limiting seat 12, and the rubber plate 13 will be pressed against the surface of the end of the sample container 4, enabling the limiting seat 12 to stably limit the position of the sample container 4.

[0022] Referring to Figure 1 and Figure 2 it can be seen that when the box body 1 shakes, the limiting seat 12 and the rubber protrusions 14 can limit the position of the sample container 4, making the sample container 4 not prone to shaking and collision.

[0023] Referring to Figure 1 , Figure 2 and Figure 3 it can be seen that fixed blocks 15 are welded on both sides of the box body 1. A sliding column 16 is slidably connected inside the fixed block 15. A clamping groove 17 is formed inside the sliding column 16. The ends of the two sliding columns 16 are jointly connected to a cross bar 18. Mounting blocks 19 are jointly welded on the outer sides of the two fixed blocks 15. A clamping pin 20 is slidably connected inside the mounting blocks 19 and the fixed blocks 15. A spring 21 is connected between the clamping pin 20 and the mounting block 19. The ends of the two clamping pins 20 are jointly connected to a connecting plate 22. Two groups of connecting plates 22 are symmetrically arranged about the center of the box body 1.

[0024] During specific implementation, the overall weight of the sample storage device and the sample containers 4 placed inside it is relatively heavy, and two people are required to carry it together. Since there is usually only one handle on the box cover 2, it is difficult for the two people to lift the box body 1 during the carrying process. For this reason, the connecting plate 22 can be pulled in a direction away from the sliding column 16. When the connecting plate 22 moves, it can drive the pin 20 to move. When the pin 20 moves, it can squeeze the spring 21. When the end of the pin 20 slides out of a set of clamping grooves 17, the cross bar 18 can be pulled. When the cross bar 18 moves, it can drive the two sliding columns 16 to slide upward. When the sliding columns 16 slide to the maximum distance, the connecting plate 22 can be released. When the connecting plate 22 is released, the pin 20 can be reset by the spring 21. When the pin 20 is reset, its end can be inserted into another set of clamping grooves 17. At this time, the pin 20 can limit the sliding column 16. When both cross bars 18 move to the specified height, the two people can respectively hold the two cross bars 18 to lift the box body 1, so as to carry the box body 1.

[0025] Referring to Figure 1 , Figure 2 and Figure 3 it can be seen that the box body 1 can be carried simply and conveniently through the two cross bars 18, and the two people can apply force better during the carrying process.

[0026] To sum up, when using this wastewater detection sample storage device, the sample container 4 containing wastewater is placed inside the placement seat 3, and the box cover 2 is closed and fixed. At this time, the box body 1 can store the wastewater sample. The sample storage device is an existing technology and will not be described in detail here. When the bottom of the pressing plate 9 moves to the surface of the box cover 2, the limiting seat 12 can move to the end of the sample container 4. At this time, the end of the sample container 4 is located inside the limiting seat 12, and the rubber plate 13 will be pressed against the surface of the end of the sample container 4, so that the limiting seat 12 can stably limit the sample container 4. When the box body 1 shakes, the sample container 4 can be limited by the limiting seat 12 and the rubber protrusions 14, so that the sample container 4 is not easy to shake and collide. When both cross bars 18 move to the specified height, the two people can respectively hold the two cross bars 18 to lift the box body 1, so as to carry the box body 1. The box body 1 can be carried simply and conveniently through the two cross bars 18, and the two people can apply force better during the carrying process. The content not described in detail in this specification belongs to the existing technology well-known to those skilled in the art.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
