Description

Technical Field

[0001] This invention relates to the field of climate simulation experimental equipment technology, specifically to a convenient climate simulation experimental chamber with intelligent control. Background Technology

[0002] Climate simulation chambers, also known as environmental test chambers or climate test chambers, are core experimental devices that can precisely control environmental parameters such as temperature, humidity, light, and air pressure in a sealed space to artificially reproduce various natural climate conditions. They are widely used in many scientific research and industrial fields, including materials performance testing, reliability verification of electronic components, crop breeding, microbial culture, and aquatic organism stress experiments. A typical climate simulation chamber mainly consists of a temperature control system, a humidity control system, a circulation system, and an intelligent control system working together. Intelligent control technology is a mature existing technology in this field, enabling precise parameter setting and automatic closed-loop control.

[0003] With the increasing demand for on-site experiments and mobile testing, the market demand for small portable climate simulation test chambers continues to grow. Such equipment needs to be able to switch between fixed laboratory use and multi-point field experiments, which puts forward higher requirements for portability, site adaptability and ease of operation.

[0004] Most existing small-scale climate simulation test chambers use a fixed chamber structure. To accommodate different operating table heights and on-site placement requirements, they typically require additional independent supports for elevation and support. The separate design of the supports and the chamber not only increases the number of handling parts but also makes on-site assembly time-consuming and labor-intensive. Furthermore, the limited height adjustment options make it difficult to flexibly adapt to the height requirements of different experimental scenarios. Regarding mobility and transport, most equipment only has casters fixed to the bottom of the chamber. When idle, the casters are prone to deformation due to prolonged load, and the protruding caster structure makes it impossible to stack the chamber stably. Equipment without casters requires transport as a whole, which is labor-intensive and extremely inconvenient for short-distance relocation. In addition, the handles of existing equipment are mostly fixed and protruding, which not only increases the overall storage volume of the chamber but also makes the protruding handles susceptible to damage during transport. Equipment without handles requires manual carrying by hugging, resulting in unreasonable force distribution and a high risk of slippage.

[0005] In general, existing small climate simulation test chambers mostly employ independent structures for support, movement, and carrying, requiring separate openings at different locations within the chamber for installation. This results in low structural integration, high component redundancy, increased manufacturing costs and equipment weight, and cumbersome operation when switching between different usage scenarios, necessitating additional tools for disassembly and adjustment. Furthermore, the inability to reuse the same mounting base for each functional structure leads to low utilization of side wall space, numerous protruding components when not in use, poor stacking stability, and multiple additional openings can negatively impact the chamber's insulation and sealing performance, reducing the accuracy of temperature and humidity control. For applications requiring frequent relocation, such as aquatic research and field electronic testing, the portability and adaptability of existing equipment are insufficient to meet the demands. Currently, there is no solution that integrates all three functions into a single side wall sliding structure. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a convenient climate simulation test chamber with intelligent control, which solves the technical problems of existing small climate simulation test chambers, such as separate support, movement, and carrying functions, low structural integration, cumbersome operation switching, large storage volume, and multiple side wall openings affecting the thermal insulation performance of the chamber.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A portable climate simulation test chamber with intelligent control includes a test chamber body, which has a built-in intelligent temperature and humidity control system. The side wall of the test chamber body is provided with a limiting mechanism, and a sliding mechanism is vertically slidably arranged on the limiting mechanism. A support mechanism is fixedly connected to the sliding mechanism, and the chamber also includes a detachable and fixed moving mechanism. The limiting mechanism includes a vertically formed sliding groove on the side wall of the simulation experimental box body, and a plurality of screw holes are distributed vertically at intervals on one side of the sliding groove. The sliding mechanism includes a slide plate that is slidably embedded in the slide groove. The slide plate has two screw holes two vertically arranged on its upper edge. A screw is threaded into the screw holes two. The screw can be screwed into the screw hole one at a corresponding height to lock the slide plate in different vertical positions of the slide groove. The support mechanism includes a fixed rod that is fixedly connected between the tops of two sliding plates on the same side, and an anti-slip sleeve is fitted on the outside of the fixed rod; The moving mechanism includes a fixed plate with a screw threaded through it. A roller is rotatably connected to the outside of the fixed plate via a support shaft. When the moving mechanism is fixed in the slide groove by the screw and screw hole and is located above the slide plate, the bottom end of the roller abuts against the top of the slide plate to limit the upward movement of the slide plate. When the moving mechanism is fixed to the lower part of the slide plate by the screw and screw hole, the roller is positioned downward and protrudes from the bottom of the simulation experimental box body to support the horizontal movement of the box body.

[0008] Furthermore, the slide is a convex horizontal cross-section structure, and there are four sets of slides, which are symmetrically distributed in pairs on the opposite side walls of the simulation experimental box body. The vertical length of the slide is equal to the height of the side wall of the simulation experimental box body.

[0009] Furthermore, the slide plate has an I-shaped horizontal cross-section structure, the cross-sectional shape of the slide plate is adapted to the cross-sectional cavity of the slide groove, the vertical length of the slide plate is less than the vertical length of the slide groove, and the diameter of the second screw hole is the same as the diameter of the first screw hole.

[0010] Furthermore, the first screw and the second screw are exactly the same in size and are both knurled head hand-tightening screws. The length of the first screw is greater than the thickness of the slide plate, and the length of the second screw is greater than the thickness of the fixing plate.

[0011] Furthermore, a locking block is provided on the lower part of the outer side of the slide plate, and a slot adapted to the shape of the locking block is opened on the lower part of the fixed plate facing the slide groove; when the moving mechanism is fixed to the lower part of the slide plate, the locking block is embedded in the slot to restrict the fixed plate from rotating circumferentially around the axis of the second screw.

[0012] Furthermore, the fixing rod is an aluminum alloy round rod, with both ends fixedly connected to the opposite sidewalls of the two sliding plates on the same side; the anti-slip sleeve is made of nitrile rubber and is bonded to the outer surface of the fixing rod with adhesive.

[0013] Furthermore, the roller is a load-bearing rubber roller with an internal rolling bearing, and the diameter of the roller is smaller than the vertical length of the fixed plate.

[0014] Furthermore, the front and rear width of the fixed plate is less than or equal to the groove width of the slide, so that the fixed plate can be embedded in the slide and slide vertically; in the stored state, the entire moving mechanism is located within the vertical range of the slide and does not exceed the upper and lower end faces of the simulation experiment box body.

[0015] Furthermore, the slide plate can slide upward along the slide groove, so that the top of the slide plate extends out of the top of the simulation experiment box body, driving the support mechanism to move upward in sync to form a handle structure that can be gripped.

[0016] Furthermore, the slide plate can slide downwards along the slide groove, so that the bottom end of the slide plate extends out of the bottom of the simulation experiment box body. It can be locked by screw one cooperating with screw holes of different heights, so that the ground support height of the simulation experiment box body can be adjusted.

[0017] Technical principle of the invention: The core inventive concept of this invention is as follows: using an integrated sliding groove on the side wall of the housing as a common mounting base, and through the vertical displacement switching of a single set of sliding components, combined with the dual-station reuse of moving components, four functions—support height adjustment, mobile transfer, manual handling, and idle storage—are integrated on the same mechanical structure, avoiding the problems of redundant parts and excessive openings in the housing caused by multiple separate structures. Its core technical principle can be divided into four parts: First, the principle of sliding guidance and anti-detachment. This invention adopts a mating structure of a convex-shaped groove and an I-shaped sliding plate, which is an optimized form of groove-type sliding pair: the two flanges of the I-shaped sliding plate are embedded in the wide cavity inside the convex-shaped groove, and the neck extends from the groove opening. This ensures that the sliding plate can slide freely vertically along the groove, while the abutment between the flanges and the inner wall of the groove restricts the lateral detachment and forward and backward deflection of the sliding plate. It has high guiding accuracy and strong anti-tipping ability. This mating structure does not require additional anti-detachment components. It can achieve the dual functions of sliding guidance and axial anti-detachment by relying on the cross-sectional shape. The structure is simple and highly reliable. At the same time, the mating surface can evenly transmit vertical loads and avoid local stress concentration.

[0018] Second, the principle of multi-station function switching. This invention uses the vertical sliding displacement of the slide plate as the core variable. By adjusting the position of the slide plate within the groove, three core working stations are formed: when the lower end of the slide plate extends beyond the bottom of the groove, it forms a support station, with the extension length being the height of the box from the ground. Multiple height adjustments are achieved through locking different screw holes; when the upper end of the slide plate extends beyond the top of the groove, it forms a carrying station, with the fixing rod moving upwards with the slide plate to form a carrying handle; when the slide plate is completely retracted into the groove, it forms a storage station, with the entire structure not exceeding the contours of the upper and lower end faces of the box. Simultaneously, the moving mechanism has two independent installation stations: when installed in the groove above the slide plate, it is a limiting station, with the lower end of the roller abutting against the top of the slide plate to restrict the slide plate from moving upwards under load; when installed below the slide plate with the roller facing downwards, it is a moving station, with the roller acting as a traveling wheel to support the movement of the box. Both stations share the same moving mechanism, achieving functional reuse through changes in installation position, avoiding the duplication of independent limiting components and independent rollers.

[0019] Third, the principle of threaded locking and auxiliary limiting. This invention uses the axial locking force of a hand-tightened screw to achieve relative fixation between the slide plate and the slide groove. After the screw is tightened, the end abuts against the bottom of the slide groove, and the static friction force generated by the positive pressure of the contact surface counteracts the sliding tendency under vertical load. With the help of multiple sets of equally spaced screw holes, reliable locking at multiple height levels can be achieved. In the moving position, an auxiliary limiting structure of locking block and locking slot is added. After the locking block is embedded in the locking slot, it can limit the circumferential rotation of the fixed plate around the screw axis, ensuring that the roller axis is always perpendicular to the side of the box, avoiding roller deflection and jamming during movement, and improving the stability of the movement process. This auxiliary limiting does not require additional locking parts, and circumferential positioning can be achieved by the structural locking, making operation convenient.

[0020] Fourth, the principle of load transfer and force balance. At the support station, the weight of the container is transferred to the sliding plate via the sidewall of the chute, and then from the bottom of the sliding plate to the placement surface. The load is evenly distributed vertically, with all four sliding plates bearing the load, resulting in balanced force and preventing the container from tilting. At the moving station, the load is transferred to the fixed plate via the sliding plate, then to the rollers via the support shaft, and finally to the ground via the rollers. The force transmission path is clear, and the components are subjected to reasonable force. At the hand-held station, the lifting force is transferred to the sliding plate via the anti-slip sleeve and the fixed rod, and then from the mating surface of the sliding plate and the chute to the container. The symmetrically arranged support mechanism on both sides ensures that the container remains level during lifting, preventing it from tilting and spilling.

[0021] Compared with the prior art, the present invention has the following technical advantages: 1. This invention utilizes the sliding cooperation between the sliding plate and the sliding groove to flexibly adjust the length of the sliding plate extending from the bottom of the chamber, achieving multi-level adjustable height of the simulation experiment chamber body above the ground. This adapts to experimental operating tables of different heights and uneven placement sites, eliminating the need for additional independent supports. Simultaneously, the moving mechanism can be repositioned to act as an upper limit component for the sliding plate in the supported state, preventing the chamber from falling under load during experiments. In the moving state, it functions as a wheel assembly to support the chamber's movement. One component performs both limiting and moving functions. This design effectively reduces the number of independent parts, avoids space waste caused by separate support and moving structures, simplifies the chamber's sidewall structure, reduces the overall weight of the equipment, and significantly improves transportation and deployment efficiency.

[0022] 2. The sliding plate of this invention can be completely retracted into the slide groove, and the moving mechanism can also be stored entirely within the vertical range of the slide groove. In the idle state, all supporting components do not exceed the upper and lower end contours of the simulation experiment box body, and the overall height of the box does not increase additionally. The shape is regular, facilitating stacking and bulk transportation, effectively reducing warehousing and logistics space costs. At the same time, when the sliding plate slides upward, it can drive the supporting mechanism to extend out of the top of the box body, forming a handle structure that can be gripped. There is no need to set additional fixed protruding handles, avoiding the risk of bumps and collisions caused by protruding handles and the increase in storage volume. The three functions of support, movement, and carrying are all realized by the same sliding mechanism. The structure has strong linkage when switching between functions, no need to disassemble or assemble additional parts, the operation logic is unified, and the operator can quickly master the use method.

[0023] 3. In this invention, screws one and two use the exact same specifications and dimensions, both being standard hand-tightening screws. This eliminates the need for custom-made fasteners of various specifications, reducing component procurement and management costs and preventing the mixing of fasteners during operation. The slides and slide plates use a unified cross-sectional specification, and the molds for the four sets of slides and corresponding slide plates are interchangeable, reducing mold-making costs. Furthermore, all functional components are modularly installed, and assembly can be completed through the slide's embedding structure, eliminating the need for complex welding or riveting processes and resulting in high production and assembly efficiency. During later maintenance, easily damaged parts such as slide plates, rollers, and fasteners can be individually disassembled and replaced without disassembling the entire housing, resulting in low maintenance costs, high replacement efficiency, and effectively extending the overall service life of the equipment. This makes it suitable for mass production and long-term operation and maintenance.

[0024] 4. All locking structures in this invention use hand-tightening screws. Operators do not need additional tools such as wrenches or screwdrivers; they can complete all operations, including adjusting the slide plate position and switching the installation position of the moving mechanism, simply by hand. The entire function switching process is short, enabling rapid conversion from the storage state to the support state, moving state, or hand-held state. For scenarios such as field experiments and multi-point flow tests, it can significantly shorten the equipment deployment and dismantling time, reducing the workload of operators. At the same time, the operation steps are simple, requiring no professional training, making it suitable for experimental personnel with different knowledge backgrounds. This effectively broadens the scope of application scenarios for the equipment and improves its ease of use.

[0025] 5. This invention employs a sliding structure combining a convex-shaped groove and an I-shaped sliding plate. The large contact area of ​​the mating surfaces ensures high guiding accuracy, effectively preventing lateral deflection and detachment of the sliding plate. Under vertical load, the force is evenly distributed, allowing it to withstand greater box weight and providing strong support stability. In the supported state, the rollers abut against the top of the sliding plate, forming a rigid limit that reliably restricts upward movement of the sliding plate, preventing sudden box drop during experiments. In the moving state, the interlocking structure of the locking block and slot restricts the circumferential rotation of the fixed plate, preventing roller deflection and subsequent jamming. These multiple limiting and guiding structures collectively ensure the structural stability of the equipment under various operating conditions, effectively reducing safety hazards during use and improving the reliability of the experimental process. Even under full load of experimental samples, the structure remains stable. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1: Support and Mobility Working Mode See Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 A portable climate simulation test chamber with intelligent control is disclosed, comprising a test chamber body 1. The test chamber body 1 is formed by bending and welding 1.2mm thick cold-rolled steel plate, with the outer wall treated with powder coating for corrosion protection, the inner wall made of 304 stainless steel, and a polyurethane insulation layer in between; the overall dimensions are 450mm long × 400mm wide × 550mm high. The test chamber body 1 incorporates a conventional temperature and humidity intelligent control system, including a controller, temperature sensor, humidity sensor, cooling and heating module, humidification and dehumidification module, and lighting module. The controller implements closed-loop parameter control based on sensor feedback. This intelligent control system is a mature existing technology in the field, and its specific circuitry and control logic will not be described in detail in this embodiment.

[0030] Limiting mechanisms 2 are provided on both the left and right side walls of the simulation test chamber body 1. The limiting mechanisms 2 provide the mounting and guiding base for the entire support equipment and are used to install the sliding mechanism 310 and the moving mechanism 330. The limiting mechanism 2 includes a vertically opened slide groove 21 on the side wall of the simulation test chamber body 1. A screw hole 22 is opened vertically on one side of the slide groove 21. The horizontal cross section of the slide groove 21 is a convex structure. The width of the groove opening (front and back direction) is 18mm, the bottom width of the groove is 28mm, and the groove depth (left and right direction, from the side wall surface inward) is 10mm. The total vertical length of a single slide groove is 550mm, which is consistent with the height of the side wall of the simulation test chamber body 1. There are four sets of slide grooves 21, with two sets symmetrically arranged on the front and back of each side wall. The screw hole 22 is an M4 internal thread hole with a hole depth of 8mm. There are 10 sets of screw holes, which are equidistantly distributed vertically along the slide groove 21. The center distance between adjacent screw holes is 50mm, which realizes multi-level height adjustment. The slide 21 can be made of aluminum alloy profile and embedded in a pre-set groove on the side wall of the box, or it can be directly stamped on the side wall steel plate, both of which are conventional processing methods in this field.

[0031] A sliding mechanism 310 is vertically slidably mounted on the limiting mechanism 2. The sliding mechanism 310 is used to install the support mechanism 320 and the moving mechanism 330, and to support the main body 1 of the simulation experiment box and adjust its height from the ground. The sliding mechanism 310 includes a sliding plate 311 that is slidably embedded in the sliding groove 21. The sliding plate 311 is an I-shaped horizontal cross-section structure made of 6061-T6 aluminum alloy profile, with a total width (front and back direction) of 27mm, a middle neck width of 17mm, and a thickness (left and right direction) of 9mm. The total vertical length of a single sliding plate is 500mm. The side walls of the sliding plate 311 near the top and bottom are provided with screw holes 312. The screw holes 312 are M4 through thread holes, and the vertical distance between the centers of the two screw holes 312 is 400mm. A rectangular block of 5mm×5mm×3mm is integrally provided 5mm below the lower set of screw holes 312. The screw hole 312 is internally threaded with screw 313. Screw 313 is an M4×12mm knurled stainless steel hand screw with an effective thread length of 10mm and a head diameter of 12mm. After tightening, the end of the screw presses against the bottom of the slide groove 21, and the position of the slide plate 311 is locked by the static friction generated by the positive pressure.

[0032] A support mechanism 320 is fixedly connected to the sliding mechanism 310. The support mechanism 320 is used to assist the operator in lifting the main body 1 of the simulation experiment box. The support mechanism 320 includes a fixing rod 321 connecting two sliding plates 311 on the same side. The fixing rod 321 is a 6061 aluminum alloy round rod with a diameter of 20mm and a length of 360mm. Both ends are fixed to the opposite side walls of the two sliding plates 311 near the top by riveting, and the connection point is 30mm from the top of the sliding plate. The fixing rod 321 is covered with an anti-slip sleeve 322. The anti-slip sleeve 322 is made of nitrile rubber with a Shore hardness of 60A, a wall thickness of 3mm, and a length of 220mm. The inner wall is coated with environmentally friendly structural adhesive and is tightly bonded to the fixing rod 321. The surface has a diamond-shaped anti-slip texture to improve grip friction.

[0033] It is also equipped with a movable mechanism 330 that can be disassembled and reassembled in two positions. The movable mechanism 330 is used to support the movement of the simulation experimental box body 1, and at the same time can restrict the vertical movement of the sliding mechanism 310. The movable mechanism 330 includes a fixed plate 331, which is made of 6061 aluminum alloy plate with a thickness (left and right direction) of 5mm, a vertical length of 85mm, and a front and back width of 16mm, which is smaller than the groove width of the slide 21, so it can be embedded in the slide 21 and slide vertically. A screw 332 is threaded through the side wall of the fixed plate 331 near the top. The screw 332 is exactly the same as the screw 313, which is an M4×12mm knurled head hand screw. A 5mm×5mm×3mm rectangular slot adapted to the locking block is opened at the lower end of the fixed plate 331 facing the slide. A support shaft 333 is fixedly connected to the lower part of the outer side wall of the fixed plate 331 away from the box. The support shaft 333 is made of 304 stainless steel, with a diameter of 8mm and a length of 15mm. The axis is set horizontally in the left and right direction. The free end of the support shaft 333 is rotatably connected to a roller 334 through a rolling bearing. The roller 334 is a load-bearing rubber roller, with the wheel body covered with natural rubber and a double ball bearing inside. It has a diameter of 50mm and a wheel width of 20mm. The axis of the roller is coaxial with the support shaft and can rotate in the vertical plane, supporting the horizontal movement of the box in the front and back direction.

[0034] The working process of this embodiment is as follows: When it is necessary to support the main body 1 of the simulation experiment box and adjust its height above the ground, push the slide plate 311 downward in the slide groove 21 so that the bottom end of the slide plate 311 extends out of the bottom of the main body 1 of the simulation experiment box. When the extension length of the slide plate 311 meets the target height above the ground, stop moving the slide plate 311, turn the screw 313 to connect the screw hole 312 at the higher position with the screw hole 22 at the same height, and complete the position locking of the slide plate 311. Then, insert the fixing plate 331 from the upper end of the slide groove 21 so that the roller 334 faces downward and is located above the slide plate 311. Adjust the height of the fixing plate 331 so that the bottom end of the roller 334 abuts against the top surface of the slide plate 311. After aligning the screw holes, turn the screw 332 to cooperate with the screw hole 22 at the corresponding height, and fix the fixing plate 331 on the slide groove 21. At this time, the roller 334 forms a rigid limit, restricting the slide plate 311 from moving upward under load. The bottom end of the slide plate 311 contacts the ground, so that the main body 1 of the simulation experiment box is lifted off the ground smoothly.

[0035] When it is necessary to move the main body 1 of the simulation experiment box, the moving mechanism 330 is adjusted to the lower part of the slide plate 311. The screw hole 312 at the lower position is connected by the screw 332 to fix the fixing plate 331 on the slide plate 311. At this time, the roller 334 is located below the slide plate 311. Push the fixing plate 331 to fit against the slide plate 311, so that the locking block is embedded in the locking slot, restricting the fixing plate 331 from rotating around the screw 332, ensuring the stability of the axis of the roller 334, and the roller 334 rolls to contact the ground, supporting the horizontal movement of the main body 1 of the simulation experiment box.

[0036] Example 2: Storage and Hand-held Working Mode See Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The overall structure of this embodiment is exactly the same as that of embodiment 1. The difference lies in the working position of the components, which corresponds to two usage scenarios: storage and carrying.

[0037] When the simulation test chamber is not in use, push the slide plate 311 to slide downwards in the slide groove 21, so that the slide plate 311 is completely retracted into the slide groove 21. The upper and lower ends of the slide plate do not exceed the upper and lower end faces of the simulation test chamber body 1. Stop moving the slide plate 311, rotate the screw 313 to connect any set of screw holes 312 with the adjacent screw hole 22, and fix the slide plate 311. Then, insert the moving mechanism 330 into the empty position in the slide groove 21, rotate the screw 332 to cooperate with the corresponding screw hole 22, and fix the fixing plate 331 in the slide groove 21, completing the overall storage of all support components. At this time, all support components do not exceed the outline of the upper and lower end faces of the simulation test chamber body 1, the height of the chamber does not increase, the shape is regular, and it can be stacked and stored stably.

[0038] When the simulation test box needs to be carried by hand, push the slide plate 311 to slide upward in the slide groove 21, so that the top of the slide plate 311 extends out of the top of the simulation test box body 1, and the support mechanism 320 moves upward synchronously with the slide plate 311; when the distance between the support mechanism 320 and the top of the simulation test box body 1 reaches 100-120mm, which is a comfortable distance for an adult to hold, stop moving the slide plate 311, turn the screw 313 to connect the screw hole 312 at the lower position with the screw hole 22 at the corresponding height, and complete the position locking of the slide plate 311; the operator holds the anti-slip sleeve 322 and applies upward force, one person can hold both anti-slip sleeves 322, or two operators can hold a set of anti-slip sleeves 322 respectively and apply force together to lift the simulation test box body 1 off the ground for short-distance transport.

[0039] Method of using this invention: This invention can switch between four working modes according to different usage needs: adjustable support height, mobile transport, hand-carrying, and idle storage. No additional tools are required to switch between modes. The specific operation methods and precautions are as follows: 1. Operation method for support height adjustment mode This mode is suitable for fixed experimental scenarios and can flexibly adjust the height of the chamber from the ground to fit the operating table or uneven ground.

[0040] First step, pre-adjust the position of the slide plates: loosen the screws corresponding to the four slide plates one by one, so that the slide plates can slide freely along the slide groove; hold the two sides of the box with both hands and push the two slide plates on the same side downwards at the same time, so that the bottom of the slide plates gradually extends out of the bottom of the box. Observe the extension length of the slide plates by referring to the screw hole positions on the slide groove, until the height of the box from the ground reaches the value required for the experiment.

[0041] The second step is to lock the skateboard position: Keep the skateboard position still, align the second screw hole at the higher position on each skateboard with the first screw hole at the corresponding height, screw one through the second screw hole and screw it into the first screw hole, and tighten it by hand until the skateboard does not move vertically or wobble to the side, thus completing the vertical locking of the skateboard.

[0042] The third step is to install the limiting and moving mechanism: Take four sets of moving mechanisms and install them from the top of the slide, so that the rollers face downwards. Adjust the height so that the bottom of the rollers can smoothly abut against the top surface of the slide plate. After aligning the screw holes, screw in the two screws and tighten them. The rollers form a rigid upper limit on the slide plate to prevent the slide plate from moving upwards under load during the experiment.

[0043] Step 4, Stability Verification: After completing all installation, gently push the four corners of the top of the enclosure to check for any wobbling. Once you confirm that the four sets of sliding plates are stable and the limits are reliable, you can start the climate simulation function to conduct the experiment. If you need to adjust the height, simply loosen screw one and screw two and repeat the above steps. If the ground is uneven, you can adjust the extension length of each individual sliding plate to keep the enclosure level.

[0044] 2. Operation method of mobile transfer mode This mode is suitable for short- to medium-distance transport within laboratories or on flat ground, replacing manual handling.

[0045] Step 1, adjust the height of the skateboard: Loosen screw one, slide the skateboard down to a suitable position, so that screw hole two at the lower position is exposed outside the groove, and tighten screw one at the higher position to initially fix the skateboard.

[0046] The second step is to install the moving rollers: With the rollers of the moving mechanism facing downwards, place the fixing plate against the outside of the skateboard, aligning the slots on the fixing plate with the blocks on the skateboard and pushing them in horizontally. At this point, screw two should be coaxially aligned with screw hole two at the lower position. Tighten screw two to firmly fix the fixing plate to the skateboard. After all four sets of moving mechanisms are installed in the same way, the entire roller support box should be about 20mm off the ground.

[0047] The third step is the transfer operation: The operator holds the upper sides of the container and applies horizontal pushing force to move the container back and forth via the rollers; when turning, a small radius turn can be achieved by applying force on one side. During the movement, be careful to avoid protruding obstacles and steps to prevent the rollers from getting stuck or the container from tipping over, and do not push it on slopes greater than 5 degrees.

[0048] Step 4, Positioning and Switching: After transferring to the target location, unscrew the second screw to remove the moving mechanism, adjust the slide to the required support height and lock it, and reinstall the limiting mechanism to enter the experimental state.

[0049] 3. Hand-held transport mode operation method This mode is suitable for short-distance transport where rollers cannot pass, such as when going up and down stairs or on uneven surfaces.

[0050] Step 1: Extend the carrying mechanism: Loosen all screws and push the slide upwards so that the top of the slide extends out of the top of the box. The fixing rod moves upwards synchronously with the slide. Stop pushing when the distance between the fixing rod and the top surface of the box reaches 100-120mm.

[0051] The second step is to lock the handle structure: Align the lower screw hole 2 with the corresponding screw hole 1, screw in the screw 1 and tighten it to fix the position of the slide plate; at this time, the fixing rod and the anti-slip sleeve form a stable handle, which is symmetrically distributed on both sides.

[0052] The third step is manual handling: When operating alone, you can hold the anti-slip sleeves on both sides with both hands, apply force evenly to lift the box upwards, and carry it short distances after keeping the box level; if the box is heavy after loading samples, two operators can hold the anti-slip sleeves on one side and carry it together, keeping the speed constant during the lifting process and avoiding violent shaking.

[0053] Step 4, Reset in place: After moving to the destination, place the box stably on the ground, loosen one screw, retract the slide plate downwards into the slide groove, and lock it again to switch to other modes.

[0054] 4. How to operate the idle storage mode This mode is used when storing materials for a long period of time or transporting them in bulk after the experiment is completed.

[0055] Step 1, retract the sliding mechanism: Loosen all screws 1, push the slide plate completely into the slide groove, ensuring that the upper and lower ends of the slide plate do not exceed the outline of the upper and lower end faces of the box, align the corresponding screw holes, and then tighten screw 1 to fix it.

[0056] The second step is to store the moving mechanism: Insert the moving mechanism from the top of the slide groove and embed it into the empty space inside the slide groove. Tighten the screws to fix it, so that the moving mechanism is completely stored within the vertical range of the slide groove and no parts protrude from the top and bottom surfaces of the box.

[0057] The third step is storage and stacking: After storage, the boxes have a neat shape with no protruding vertical parts, and can be stacked stably to save storage space.

[0058] Precautions for use: (1) Each screw should be tightened by hand to avoid excessive force causing the threads to strip and affecting the reliability of the locking. (2) A small amount of silicone-based grease should be applied to the slide every 3 months to ensure smooth sliding of the slide plate and avoid jamming and abnormal wear; (3) The rated load of a single roller shall not exceed 15kg, and the total load of the whole machine shall not exceed 60kg. Overloading is prohibited to avoid deformation and damage to the components. (4) When the slide is left idle for a long time, the dust and stains on the surface of the slide and the slide plate should be cleaned to avoid the accumulation of impurities affecting the sliding performance and locking accuracy.
