Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, specifically to a soil testing sample storage device. Background Technology

[0002] Soil testing is an important process in environmental monitoring and is key to determining whether the environment is polluted. Therefore, in order to understand whether the environment is polluted, it is necessary to take soil samples from the environment and transfer the soil samples to the laboratory for relevant component testing. At this time, the transfer of soil samples needs to be achieved with the help of sample storage devices.

[0003] Currently, commercially available containers for soil sampling are typically test tubes, with the soil sample placed inside and the opening sealed. Furthermore, a sample storage device is needed to transfer these soil sampling containers. The industry typically uses a large box with several shelves inside, each shelf having several placement holes. Test tubes containing coarse soil samples are placed in their corresponding holes, allowing for the simultaneous transfer of multiple soil samples. While this sample storage device meets the transfer requirements, its internal shelves are arranged vertically. During use, all shelves must be removed from the box first, and the next shelf must be placed after the bottom shelf is installed, and so on until the last shelf is installed. In laboratory testing, the top shelf must be removed first, and all shelves must be removed from top to bottom to retrieve all the test tubes containing soil samples. This limitation prevents direct placement of test tubes on any shelf, thus restricting its use. Summary of the Invention

[0004] To address the aforementioned problems in existing technologies, this invention aims to provide a soil testing sample storage device. This device incorporates a retractable lifting frame within a housing. The side of the lifting frame features a bracket with several shelves, exposing each shelf on both sides for easy access to soil samples from all shelves. An inclined connecting rod connects the side of the bracket to the side of the lifting frame, and a push spring connects the connecting rod to the lifting frame. Folding the connecting rod and compressing the push spring allows the bracket to be stored within the housing. Pulling the lifting frame upwards raises the bracket and moves it outside the housing, while the connecting rod unfolds under the action of the push spring, pushing the bracket towards both sides of the housing. This provides sufficient space on both sides of the bracket for accessing all soil samples, making the device more convenient and reducing usage limitations.

[0005] The specific technical solution is as follows: A soil testing sample storage device includes a box, and further includes a lifting frame, a bracket, a connecting rod, and a push spring. The lifting frame is arranged vertically and slidably mounted on the inner wall of the box. A bracket is provided inside the box and located on the side of the lifting frame. Several layers of shelves are arranged vertically on the bracket, and each shelf has several storage holes. The two sides of the bracket are open surfaces. An inclined connecting rod is provided between the end of the bracket and the lifting frame. The two ends of the connecting rod are respectively hinged to the bracket and the lifting frame. A compressed push spring is provided between the lifting frame and the connecting rod.

[0006] In the aforementioned soil testing sample storage device, a lifting frame is located in the middle of the box, and brackets are provided on both sides of the lifting frame. The lifting frame includes a slider and a pull rod. A groove is provided on the inner side wall of the box along the vertical direction. The slider is slidably disposed in the groove. The pull rod is connected to the upper part of the slider. A connecting rod is hinged to the slider. One end of a push spring is connected to the slider.

[0007] In the aforementioned soil testing sample storage device, each connecting rod is tilted upwards on the lifting frame, and the point where the connecting rod is connected to the bracket is higher than the point where it is connected to the lifting frame.

[0008] In the aforementioned soil testing sample storage device, two sets of lifting frames are provided. The two sets of lifting frames are symmetrically arranged inside the box and respectively located at both ends of the bracket. An upper connecting rod is provided between the top of the pull rods of the two sets of lifting frames, and a lower connecting rod is provided between the bottom of the sliders of the two sets of lifting frames.

[0009] In the aforementioned soil testing sample storage device, the bottom surface of each bracket is an inclined guide surface, and the lowest point of the guide surface is located on the side close to the lifting frame.

[0010] In the aforementioned soil testing sample storage device, clearance grooves are provided on both sides of the slider, one end of the push spring connected to the slider extends into the clearance groove, and a notch is provided on the side of the connecting rod near the slider, one end of the push spring connected to the connecting rod extends into the notch.

[0011] In the aforementioned soil testing sample storage device, positioning holes are provided on both the slider and the pull rod. At the same time, a locking hole penetrating into the slide groove is provided on the side wall of the box. When a pin is inserted into a positioning hole, it is also simultaneously inserted into the locking hole.

[0012] In the aforementioned soil testing sample storage device, pulleys are provided at the bottom and top of the bracket, on the side opposite to the lifting frame, and the inner edge of the upper opening of the box is provided with a rounded chamfer.

[0013] The aforementioned soil testing sample storage device has wheels installed at the bottom of the container.

[0014] In the aforementioned soil testing sample storage device, when sealing is required, a flip-top is provided at the upper opening of the box, and when the lifting frame is in its lowest position, the upper end of the pull rod is below the upper opening of the box; or when there is no sealing requirement, the upper end of the pull rod extends beyond the upper opening of the box.

[0015] The positive effects of the above technical solution are: The aforementioned soil sample storage device features a vertically mounted lifting frame inside the housing, with a shelf containing multiple shelves located beside the lifting frame. The shelf has open sides, allowing operators to easily access soil samples from any shelf, enhancing usability. A connecting rod and a push spring connect the lifting frame and the connecting rod. When the shelf moves outside the housing, the push spring deflects the connecting rod, pushing the shelf outwards. This provides space on both sides of the shelf for soil sample access, further simplifying operation and reducing limitations. Conversely, when the lifting frame is depressed, the shelf retracts towards the lifting frame, folding the connecting rod and compressing the push spring, allowing the shelf to retract inwards and move back into the housing, fulfilling transport requirements.

[0018] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 5 The technical solution provided by this utility model is described in detail, but the following content is not intended to limit this utility model.

[0019] Figure 1 This is a structural diagram of a soil testing sample storage device of the present invention in its recovery state. Figure 2 This is a partial cross-sectional view of a soil testing sample storage device according to an embodiment of the present invention in its recovery state; Figure 3 for Figure 2 An enlarged view of part A in the image. (See image below.) Figure 1 and Figure 2 As shown, the soil sample storage device provided in this embodiment includes: a housing 1, a lifting frame 2, a bracket 3, a connecting rod 4, and a pushing spring 5. In this case, the housing 1, as the outermost protective structure, enables the storage and transfer of all soil samples.

[0020] Figure 4 This is a structural diagram of an embodiment of a soil testing sample storage device of the present invention, showing the bracket moved upwards to be flush with the upper opening of the box; Figure 5 This is a structural diagram of the tray after it has been pushed outwards in an embodiment of a soil testing sample storage device according to this utility model. Figures 1 to 5As shown, the lifting frame 2 is arranged vertically and slidably mounted on the inner wall of the housing 1, allowing the operator to change the position of the lifting frame 2 within the housing 1 by pulling or pressing it down. This facilitates the subsequent inward retraction and outward extension of the bracket 3. Furthermore, a bracket 3 is located inside the housing 1 and on the side of the lifting frame 2. Several layers of spaced shelves 31 are arranged vertically on the bracket 3, each shelf 31 having several storage holes 311. This allows test tubes containing soil samples to be stably placed on the bracket 3 through the storage holes 311, meeting the soil sample storage requirements. Additionally, the sides of the bracket 3 are open, directly exposing both sides of each shelf 31, allowing the operator to easily access soil samples from any shelf 31 from either side of the bracket 3, simplifying its use and reducing limitations. Furthermore, an inclined connecting rod 4 is provided between the end of the bracket 3 and the lifting frame 2. The two ends of the connecting rod 4 are respectively hinged to the bracket 3 and the lifting frame 2. The connecting rod 4 connects the bracket 3 and the lifting frame 2, thus providing conditions for the subsequent raising or lowering of the bracket 3 inside the box 1 by the lifting frame 2, as well as for pushing it outward or retracting it inward after it is moved outside the box 1. In addition, a compressed push spring 5 is provided between the lifting frame 2 and the connecting rod 4, so that the push spring 5 can push the connecting rod 4 to deflect on the lifting frame 2. After the bracket 3 is moved outside the box 1, the push spring 5 extends and pushes the connecting rod 4 to unfold, pushing the bracket 3 outward through the connecting rod 4. This provides sufficient space on both sides of the bracket 3, making it convenient for operators to pick up and put down soil samples on any shelf 31 on the bracket 3, thus reducing usage restrictions. It is worth noting that each bracket 3 has two sets of connecting rods 4, which are respectively hinged to the upper and lower parts of the bracket 3. That is, the lifting frame 2, the two sets of connecting rods 4 and the bracket 3 can form an approximately parallelogram structure, which makes the bracket 3 move more smoothly relative to the lifting frame 2 and the structural design more reasonable.

[0021] More specifically, the lifting frame 2 is positioned in the middle of the housing 1, providing space on both sides for the brackets 3. With brackets 3 on both sides, the lifting frame 2 can simultaneously control both brackets 3, improving structural utilization and maintaining balance on both sides, facilitating lifting operations. Furthermore, the lifting frame 2 includes a slider 21 and a pull rod 22. A vertical groove 11 is formed on the inner wall of the housing 1, within which the slider 21 slides. The pull rod 22 is connected to the upper part of the slider 21, allowing the operator to control the slider 21's movement within the groove 11, making it more convenient to use. Simultaneously, a connecting rod 4 is hinged to the slider 21, and one end of a push spring 5 is connected to the slider 21.

[0022] More specifically, each link 4 is tilted upwards on the lifting frame 2. The point where the link 4 is connected to the bracket 3 is higher than the point where it is connected to the lifting frame 2. This allows the link 4 to push the bracket 3 upwards with an upward force when the bracket 3 moves upwards inside the housing 1. Furthermore, when the bracket 3 reaches the top, it will push outwards. At this time, the link 4 can follow the outward movement of the bracket 3. At the same time, it also allows the link 4 to pull the bracket 3 downwards when it moves downwards, which better follows the direction of movement of the bracket 3 and makes the structural design more reasonable.

[0023] More specifically, the lifting frame 2 is provided in two sets, which are symmetrically arranged inside the housing 1 and respectively located at both ends of the bracket 3, so that each end of the bracket 3 is supported by a corresponding lifting frame 2, ensuring the stability of the bracket 3 after installation. In addition, an upper connecting rod 23 is provided between the top of the pull rods 22 of the two sets of lifting frames 2, and a lower connecting rod 24 is provided between the bottom of the sliders 21 of the two sets of lifting frames 2. This allows the two sets of lifting frames 2, the upper connecting rod 23, and the lower connecting rod 24 to form a rectangular structure. This not only ensures that the sliders 21 of the two lifting frames 2 can rise and fall synchronously, improving structural stability and reliability, but also makes it easier for operators to pull or press down the two lifting frames 2 using the upper connecting rod 23, making it more convenient to use.

[0024] More specifically, the bottom surface of each bracket 3 is an inclined guide surface 32, and the lowest point of the guide surface 32 is located on the side close to the lifting frame 2. This allows the bracket 3 to interact with the edge of the container 1 under the action of the guide surface 32 when the lifting frame 2 is pressed down. This allows the bracket 3 to move inward along the guide surface 32 towards the inside of the container 1, that is, the bracket 3 slides towards the side of the lifting frame 2, realizing the inward retraction of the bracket 3. At this time, the connecting rod 4 can follow the movement of the bracket 3, realizing the folding of the connecting rod 4 relative to the lifting frame 2 and the bracket 3, and compressing the push spring 5, providing power for the subsequent outward push of the bracket 3. At the same time, when it is necessary to retract the bracket 3 into the container 1, the operator only needs to press down the lifting frame 2 to complete the task, without any additional operation, making it more convenient to use.

[0025] More specifically, both sides of the slider 21 are provided with clearance grooves 211. One end of the push spring 5 connected to the slider 21 extends into the clearance groove 211. Preferably, the connecting rod 4 is provided with a notch 41 on the side near the slider 21. One end of the push spring 5 connected to the connecting rod 4 extends into the notch 41. The clearance grooves 211 and the notch 41 provide installation and movement space for the push spring 5, so that the push spring 5 can be installed in a hidden manner, avoiding interference with the deflection of the connecting rod 4 caused by the push spring 5. This allows the connecting rod 4 to retract more tightly relative to the slider 21, resulting in a more compact structure. As a result, a larger bracket 3 can be set, and the space utilization is more reasonable.

[0026] More specifically, both the slider 21 and the pull rod 22 are provided with positioning holes 212. At the same time, a locking hole is provided on the side wall of the housing 1, which extends into the slide groove 11. This allows the slider 21 to be inserted into the positioning hole 212 by means of a pin when it moves up or down, and to be inserted into the locking hole at the same time. This achieves temporary fixation of the slider 21, preventing the lifting frame 2 from rising or falling unexpectedly. This also prevents the bracket 3 from retracting inward or pushing outward unexpectedly, thus improving the structural reliability and safety of use.

[0027] More specifically, pulleys 33 are provided at the bottom and top of the bracket 3, on the side opposite to the lifting frame 2. This allows the bracket 3 to contact the inner wall of the box 1 via the pulleys 33 as it moves within the box 1, reducing friction between the bracket 3 and the box 1. This not only makes it easier to use but also prevents structural wear and extends its service life. Simultaneously, the inner edge of the upper opening of the box 1 is rounded, allowing the guide surface 32 of the bracket 3 to contact the guide surface 32 when they mate, facilitating the inward retraction of the bracket 3 and resulting in a more rational structural design.

[0028] More specifically, the bottom of the housing 1 is provided with wheels 6. Preferably, the wheels 6 are omnidirectional wheels, which facilitates the movement of the entire device and makes it more convenient to use.

[0029] More specifically, when sealing is required, a flap is provided at the upper opening of the box 1. When the lifting frame 2 is in its lowest position, the upper end of the pull rod 22 is below the upper opening of the box 1. This means that after the soil sample is stored inside the box 1, the flap can seal the upper opening, achieving a seal on the internal space of the box 1. When sealing is not required, the upper end of the pull rod 22 can extend beyond the upper opening of the box 1, facilitating operation and resulting in a more rational structural design. It is worth noting that when sealing is required, a sealing ring is provided at the opening of the locking hole on the box 1. When the pin is inserted into a positioning hole 212 and the locking hole, the sealing ring ensures a seal with the pin, guaranteeing the sealing effect of the box 1.

[0030] The soil testing sample storage device provided in this embodiment includes a box 1, a lifting frame 2, a bracket 3, a connecting rod 4, and a push spring 5. The lifting frame 2 is arranged vertically inside the box 1. At the same time, a bracket 3 with several layers 31 is hinged to the side of the lifting frame 2 by the connecting rod 4. The two sides of the bracket 3 are open, so that the operator can take soil samples from any layer 31 from both sides of the bracket 3. Furthermore, a push spring is provided between the lifting frame 2 and the connecting rod 4. When the bracket 3 moves to the outside of the box 1, the push spring 5 can push the connecting rod 4 to deflect and push the bracket 3 outward. This provides space on both sides of the bracket 3 for taking soil samples, making it more convenient to use and reducing usage restrictions. When the lifting frame 2 is pressed down, the bracket 3 can be pulled inward and moved down into the box 1 to meet the transportation needs.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
