Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring auxiliary equipment technology, and in particular to an environmental monitoring sample storage and transportation device. Background Technology

[0002] In environmental monitoring, the collection and transportation of samples are crucial to ensuring the accuracy of monitoring data. Environmental monitoring samples (such as water, soil, and gas adsorbents) often have stringent requirements for storage environment to avoid pollution, leakage, and volatilization.

[0003] Currently, traditional sample storage and transportation devices mostly use ordinary boxes or single storage spaces, which have the following problems: First, they lack classified storage structures, and the mixing of liquid and solid samples can easily lead to cross-contamination, and it is difficult to provide dedicated protection for the characteristics of different samples (such as volatility and deliquescence); Second, the sealing performance is insufficient, and most devices are only sealed with simple box covers, and gaps can easily allow external dust and moisture to enter, or samples to leak and pollute the environment. The locking structure has poor stability, and bumps during transportation can easily cause the storage chamber door to open accidentally, increasing the risk of sample damage; Third, they lack mobility, and some devices do not have dedicated pull rods or casters, which consumes manpower when transporting long distances.

[0013] Compared with related technologies, the environmental monitoring sample storage and transportation device provided by this utility model has the following beneficial effects:

[0014] 1. By setting up a storage and transportation box, different types of samples such as liquids and solids can be stored separately through two independent storage chambers in the storage and transportation box, avoiding cross-contamination. The sealing cover, together with the sealing rubber ring on the lower surface, can fit tightly against the edge of the storage chamber, effectively filling gaps and blocking the contact between external dust and moisture and the internal samples. At the same time, it prevents the leakage of volatile samples, providing a clean and stable storage environment for the samples and ensuring that their properties are not disturbed during the storage stage.

[0015] 2. By incorporating a locking structure, which achieves automatic locking through the linkage of a sliding block, guide rod, locking tongue, and spring, the spring pushes the locking tongue into the lock hole in the storage chamber wall under normal conditions, ensuring that the sealing cover will not be accidentally opened during transportation. The sliding switch design combines convenient operation with anti-accidental touch function, requiring only a slide to unlock and automatically resetting and locking after releasing the hand, thus solving the problem of unstable locking in traditional devices and improving the safety of sample transportation.

[0016] 3. Equipped with a connecting plate, pull rod, and casters, the four casters at the bottom of the storage and transportation box allow for flexible steering. In conjunction with the pull rod on the upper part of the connecting plate, operators can pull out the pull rod and drag it to easily move the device, significantly reducing the manpower required for long-distance transportation. The arc groove on the upper part of the connecting plate further improves the smoothness of the pull rod, making transportation operations more labor-saving and suitable for short-distance or long-distance movement needs in various scenarios such as laboratories and sampling points.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4The system includes: a storage and transportation box 1, a sealing cover 2, a locking structure 3, a connecting plate 4, and a pull rod 5. The storage and transportation box 1 has two storage chambers inside, which are the direct storage spaces for environmental monitoring samples. This allows for the classified storage of different samples, such as separating liquid and solid samples. Both storage chambers have sealing covers 2 hinged to their inner walls. Each sealing cover 2 has a cavity inside, and each cavity contains a locking structure 3. The locking structure 3 includes a sliding block 6 and a guide rod 7. The locking tongue 8 and the sliding block 6 are slidably connected to the cavity of the sealing cover. One end of the sliding block 6 has a through hole, and a guide rod 7 is slidably connected inside the through hole at one end of the sliding block 6. The locking tongue 8 is fixedly connected to one end of the sliding block 6. A connecting plate 4 is fixedly connected to the outer surface of one side of the storage and transportation box 1. Two cavities are opened at the upper end of the connecting plate 4. A pull rod 5 is set at the upper end of the connecting plate 4. The connecting plate 4 provides an installation carrier for the pull rod 5. The pull rod 5 is inverted "U" shaped. The lower end of the pull rod 5 is slidably connected to the two cavities at the upper end of the connecting plate 4 respectively.

[0024] In the specific implementation process, a box cover 9 is hinged to one side of the storage and transportation box 1. The box cover 9 is hinged to one side of the storage and transportation box 1 and can be flipped open and closed, which plays a sealing role for the entire storage and transportation box 1, preventing external dust, moisture or debris from entering the box and contaminating the sample. Four universal wheels 10 are installed on the lower surface of the storage and transportation box 1. The universal rotation characteristics of the universal wheels 10 make it convenient for operators to push or turn the storage and transportation box 1, reducing the difficulty of handling the sample during transportation. Lock holes are opened in the inner walls of the storage and transportation box 1 at two storage chambers.

[0025] The upper end of the connecting plate 4 is provided with an arc-shaped groove, which is located below the pull rod 5. The arc-shaped groove makes it convenient for the operator to pull the pull rod 5.

[0026] The sealing cover 2 has a sealing rubber ring 11 fixedly connected to its lower surface. When the sealing cover 2 is closed, the sealing rubber ring 11 fits tightly against the edge of the storage chamber of the storage box 1, filling the gap between the sealing cover 2 and the storage chamber of the storage box 1 and enhancing the sealing performance of the storage chamber of the storage box 1. The upper surface of the sealing cover 2 has a guide groove, and a sliding switch 12 is slidably connected inside the guide groove. The bottom of the guide groove on the upper surface of the sealing cover 2 has a connecting groove, which is connected to the cavity inside the sealing cover 2. The lower end of the sliding switch 12 extends through the bottom connecting groove in the guide groove on the upper surface of the sealing cover 2 and into the cavity inside the sealing cover 2. The lower end of the sliding switch 12 is fixedly connected to the upper end of the sliding block 6. One end of the sealing cover 2 has a through groove, which is connected to the cavity inside the sealing cover 2.

[0027] Among them, a spring 13 is fixedly connected to the end of the sliding block 6 away from the locking tongue 8. The spring 13 is sleeved on the outer surface of the guide slide rod 7. The two ends of the guide slide rod 7 are respectively fixedly connected to the inner wall of the cavity of the sealing cover plate 2. The end of the spring 13 away from the sliding block 6 is fixedly connected to the inner wall of the cavity of the sealing cover plate 2. The sliding switch 12 slides in the guide groove of the sealing cover plate 2, which drives the sliding block 6 to move and compress the spring 13. The locking tongue 8 disengages from the lock hole, realizing the unlocking operation of the locking structure 3. Under normal conditions, the spring 13 pushes the sliding block 6 to drive the locking tongue 8 to insert into the lock hole, keeping the sealing cover plate 2 locked. When unlocking, the spring 13 is compressed. After releasing, the locking tongue 8 automatically resets and locks under the elastic force of the spring 13.

[0028] Among them, the locking tongue 8 extends through the groove of the sealing cover plate 2 at one end away from the sliding block 6 and into the lock hole of the inner wall of the storage chamber. When the locking tongue 8 is in the locked state, it passes through the groove of the sealing cover plate 2 and inserts into the lock hole of the storage chamber wall, directly realizing the mechanical fixation between the sealing cover plate 2 and the storage chamber.

[0029] The working principle of this utility model is as follows: When storing environmental monitoring samples, the operator first opens the hinged cover 9 on one side of the storage box 1 by flipping it open, and then slides the sliding switch 12 in the guide groove on the upper surface of the sealing cover plate 2. The lower end of the sliding switch 12 passes through the connecting groove, causing the sliding block 6 in the cavity of the sealing cover plate 2 to slide along the guide rod 7, so that the spring 13 at the end of the sliding block 6 away from the locking tongue 8 is compressed. At the same time, the locking tongue 8 at the other end of the sliding block 6 is pulled out from the lock hole in the inner wall of the storage chamber and retracted into the through groove of the sealing cover plate 2, thereby unlocking the locking structure 3. Then, the sealing cover plate 2 hinged to the inner wall of the storage chamber can be flipped open to store different types of environmental monitoring samples, including liquids and solids. The specimens are placed in two storage chambers respectively. Then, the sliding switch 12 is operated in reverse. After being released, the spring 13 pushes the sliding block 6 to reset under the action of elastic force, so that the locking tongue 8 passes through the through groove and inserts into the lock hole to complete the locking of the sealing cover 2. At this time, the sealing rubber ring 11 on the lower surface of the sealing cover 2 fits tightly with the edge of the storage chamber to enhance the sealing performance. Finally, the box cover 9 is closed to complete the specimen storage. During transportation, the operator can hold the inverted "U"-shaped pull rod 5 and adjust the height by sliding the lower end of the pull rod 5 inside the cavity of the connecting plate 4. The arc groove on the upper end of the connecting plate 4 can be used for easy pulling. With the help of the four universal wheels 10 on the lower surface of the storage and transportation box 1, the whole can be moved conveniently.
