The outer wall of the slide cylinder is slidably fitted to the inner wall of the central column. The outer wall of the first slider is slidably fitted to the inner walls of the first arc-shaped groove and the first square groove. The first arc-shaped groove is located at the bottom of the guide groove, and the inner wall of the first arc-shaped groove is connected to the inner wall of the guide groove. The outer wall of the first slider is slidably fitted to the inner wall of the guide groove.

[0007] As a preferred technical solution of this utility model: the steering adjustment assembly includes a motor fixedly installed on the top of a support base, a coupling fixedly sleeved on the outer edge of the output shaft of the motor, a worm gear fixedly sleeved on the inner wall of the coupling, a rotating shaft rotatably connected to the inner wall of the central column, a worm wheel fixedly sleeved on the bottom of the rotating shaft, and a lead screw fixedly installed on the top of the rotating shaft.

[0008] As a preferred technical solution of this utility model: the outer edge of the worm gear is staggered and meshed with the outer edge of the worm wheel, the inner walls of the three slide cylinders are provided with threads, and the threads are staggered and meshed with the outer wall threads of the lead screw, and the motor is electrically connected to the start button and the stop button respectively.

[0009] As a preferred technical solution of this utility model: the triggering component includes a second square groove opened in the inner wall of the carrier box, the inner cavity of the second square groove is respectively provided with a silicone sleeve, a sensor and a spring, the bottom of the silicone sleeve is fixedly installed with a striker, the top of the slide is provided with a corrugated telescopic plate, and the bottom of the corrugated telescopic plate is respectively fixedly installed with a second slider and a third slider.

[0010] As a preferred technical solution of this utility model: the bottom shape of the silicone sleeve is larger than the top opening shape of the second square groove, and the bottom of the silicone sleeve is slidably fitted to the inner wall of the second square groove. The spring is located at the bottom of the silicone sleeve, with one end overlapping the bottom of the silicone sleeve and the other end overlapping the inner wall of the second square groove. The sensor is located at the bottom of the striker and is electrically connected to the indicator light and the display screen.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This laboratory testing storage device utilizes the outer edge of the motor's output shaft to drive a worm gear through a coupling. The worm wheel, through meshing with the worm gear, drives a rotating shaft and a lead screw to rotate. The rotating lead screw engages with a sliding cylinder, causing the sliding cylinder to first change direction using the rotation of the lead screw. This causes the first slider and the carrier box to simultaneously rotate from the initial section of the first arc-shaped groove to the end, thereby enabling the testing equipment stored in the trigger component inside the carrier box to be retrieved from the inner cavity of the box. Simultaneously, the continuous rotation of the lead screw causes the sliding cylinder to slide and rise along the inner wall of the guide groove, simultaneously driving the first slider and the carrier box to a suitable height for the operator. This facilitates the operator placing the testing equipment in the silicone sleeve. Therefore, the sliding cylinder, the first slider, the carrier box, and the trigger component can be stored again through the reverse operation, thus adapting to the operating needs of operators of different heights.

[0013] 2. This laboratory testing storage device utilizes the elastic properties of silicone sleeves. Its soft surface can tightly adhere to the outer wall of fragile equipment, forming a protective enclosure. When no equipment is present, a spring lifts the silicone sleeve, separating the striker from the sensor. The sensor then sends an empty signal to the indicator light, which illuminates red, visually indicating that equipment can be placed. When equipment is present, its weight presses the silicone sleeve down, triggering the sensor. The sensor then sends an occupied signal, and the indicator light switches to green, indicating that the equipment has been stored. This effectively reduces the risk of repeated placement and accidental omissions. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 6 A storage device for laboratory testing includes a support base 1. A central column 2 and a housing 6 are fixedly installed on the top of the support base 1. The outer wall of the central column 2 is provided with a first arc-shaped groove 3 and a guide groove 4. The inner wall of the guide groove 4 is provided with a sliding groove 5. The outer wall of the housing 6 is provided with a first square groove 7. The outer wall of the housing 6 is provided with a start button 8, a stop button 9 and a sealing cover 12. The outer wall of the sealing cover 12 is provided with an indicator light 10 and a display screen 11. The inner cavity of the central column 2 is provided with a steering adjustment component 13 and a slide cylinder 14. The top of the slide cylinder 14 is provided with a second arc-shaped groove 15. One end of a first slider 16 is fixedly installed on the outer wall of the slide cylinder 14. The other end of the first slider 16 is fixedly installed with a carrier box 17. The inner cavity of the carrier box 17 is provided with a trigger component 18.

[0023] In the above structure, the first arc-shaped groove 3 and the guide groove 4 opened on the outer wall of the central column 2 provide guide paths for the first slider 16 to turn and slide, and to lift and slide, respectively, so that the first slider 16 and the carrier box 17 can slide more smoothly when turning and lifting.

[0024] In a preferred embodiment: the first arc-shaped groove 3, guide groove 4, slide groove 5, first square groove 7, start button 8, stop button 9, indicator light 10, display screen 11, sealing cover 12, steering adjustment assembly 13, slide cylinder 14, second arc-shaped groove 15, first slider 16, carrier box 17 and trigger assembly 18 are regarded as a set of movable components, and there are three sets of such movable components, which are arranged in parallel. The outer wall of the slide cylinder 14 is slidably attached to the inner wall of the central column 2. The outer wall of the first slider 16 is slidably attached to the inner walls of the first arc-shaped groove 3 and the first square groove 7. The first arc-shaped groove 3 is located at the bottom of the guide groove 4, and the inner wall of the first arc-shaped groove 3 is connected to the inner wall of the guide groove 4. The outer wall of the first slider 16 is slidably attached to the inner wall of the guide groove 4.

[0025] In the above structure, by setting the movable components consisting of the first arc-shaped groove 3, guide groove 4, slide groove 5, first square groove 7, start button 8, stop button 9, indicator light 10, display screen 11, sealing cover 12, steering adjustment assembly 13, slide cylinder 14, second arc-shaped groove 15, first slider 16, carrier box 17, and trigger assembly 18 into three groups and arranged in parallel, the storage capacity of the device is improved, and multiple sets of testing equipment can be stored simultaneously. First, the first slider 16 is located on one side of the inner wall of the first arc-shaped groove 3, so that the slide cylinder 14 rotates under the drive of the lead screw 136. The rotating slide cylinder 14 will synchronously drive the first slider 16 to slide along the inner wall of the first arc-shaped groove 3 to the other side. Second, the sliding first slider 16 will drive the carrier box 17, which is fixed to it at one end, to slide along the first square groove 7. The inner wall of the carrier box 17 slides, causing the carrier box 17 to rotate to ninety degrees in sync with the sliding of the first slider 16, moving from the inner cavity of the box 6 to the outside of the equipment. At this time, after the first slider 16 slides to one end, its sliding cylinder 14 drives the first slider 16 to slide upward along the inner wall of the central column 2 via the lead screw 136. The sliding first slider 16 will simultaneously drive the carrier box 17 to move upward, thereby moving it to a suitable height for the operator to place the testing equipment in the inner cavity of the carrier box 17. Then, by performing the reverse operation, the sliding cylinder 14 and the first slider 16 can be moved downward, and the carrier box 17 will again slide and rotate into the inner cavity of the box 6 via the sliding of the first slider 16, thus achieving the effect of storing the testing equipment.

[0026] In a preferred embodiment: the steering adjustment assembly 13 includes a motor 131 fixedly mounted on the top of the support base 1, a coupling 132 fixedly sleeved on the outer edge of the output shaft of the motor 131, a worm gear 133 fixedly sleeved on the inner wall of the coupling 132, a rotating shaft 134 rotatably connected to the inner wall of the center column 2, a worm wheel 135 fixedly sleeved on the bottom of the rotating shaft 134, and a lead screw 136 fixedly mounted on the top of the rotating shaft 134.

[0027] In a preferred embodiment: the outer helix of the worm 133 is staggered and meshed with the outer teeth of the worm wheel 135; the inner walls of the three slide cylinders 14 are provided with threads, and the threads are staggered and meshed with the outer threads of the lead screw 136; the motor 131 is electrically connected to the start button 8 and the stop button 9 respectively.

[0028] In the above structure, pressing the start button 8 first sends a start signal to the motor 131, causing the outer edge of the output shaft of the motor 131 to drive the worm 133 to rotate via the coupling 132. Since the outer spiral of the worm 133 meshes with the outer teeth of the worm wheel 135, the worm 133 drives the worm wheel 135 to rotate. This, in turn, causes the rotating shaft 134, which is fixedly sleeved on the inner wall of the worm wheel 135, to rotate. The rotation of the rotating shaft 134 then drives the lead screw 136, which is fixedly mounted at the top, to rotate. This rotation, due to the inner wall of the slide cylinder 14... The threads on the outer wall of the lead screw 136 are interlocked and meshed, so that the slide cylinder 14 will first drive the first slider 16 to turn through the first arc groove 3 due to the rotation of the lead screw 136, and then drive the first slider 16 to move upward through the guide groove 4. This realizes the removal of the bearing box 17 from the inner cavity of the box body 6, and then the lifting effect. At the same time, due to the self-locking property of the worm gear 133, after the slide cylinder 14 moves to a suitable height, the motor 131 is stopped by pressing the stop button 9, and the worm gear 135 is stably fixed by the self-locking property of the worm gear 133.

[0029] In a preferred embodiment: the trigger assembly 18 includes a second square groove 181 opened in the inner wall of the carrier box 17. The inner cavity of the second square groove 181 is respectively provided with a silicone sleeve 182, a sensor 184 and a spring 185. A striker 183 is fixedly installed at the bottom of the silicone sleeve 182. A corrugated telescopic plate 186 is provided at the top of the slide cylinder 14. A second slider 187 and a third slider 188 are fixedly installed at the bottom of the corrugated telescopic plate 186.

[0030] In a preferred embodiment: the bottom shape of the silicone sleeve 182 is larger than the top opening shape of the second square groove 181, and the bottom of the silicone sleeve 182 is slidably fitted against the inner wall of the second square groove 181. The spring 185 is located at the bottom of the silicone sleeve 182, with one end overlapping the bottom of the silicone sleeve 182 and the other end overlapping the inner wall of the second square groove 181. The sensor 184 is located at the bottom of the striker 183 and is electrically connected to the indicator light 10 and the display screen 11. One end of the corrugated telescopic plate 186 is connected and fixed to the inner wall of the guide groove 4, and the other end is slidably connected to the top of the slide cylinder 14.

[0031] In the above structure, firstly, when the detection device is not placed on top of the silicone sleeve 182, its striking pin 183 and silicone sleeve 182 are not in contact with the sensor 184 due to the elastic force of the spring 185. This causes the sensor 184 to transmit a signal indicating the absence of the device to the indicator light 10, causing the indicator light 10 to illuminate red. Secondly, by setting multiple sets of trigger components 18, the sensors 184 in the corresponding trigger components convert the signals into digital values ​​displayed on the screen 11. This allows operators to classify and store the device according to the numbers on the display screen 11 when removing or placing it. Secondly, when the detection device is placed on top of the silicone sleeve 182, the silicone sleeve 182, due to its own characteristics, protects and wraps the detection device. Furthermore, the silicone sleeve 182 will slide along the inner wall of the second square groove 181 due to the weight of the detection device itself. This sliding motion synchronously drives the spring 185 at the bottom. The compression causes the bottom-mounted striker 183 to slide closer to the sensor 184. When the striker 183 contacts the sensor 184, the sensor 184 sends a conversion signal to the indicator light 10, causing the indicator light 10 to change from red to green. This alerts the staff that the trigger component 18 has stored the corresponding detection equipment. Simultaneously, the trigger component 18 is configured so that when the slide cylinder 14 rotates, the second arc groove 15 rotates synchronously with the rotation of the slide cylinder 14. The rotating second arc groove 15 slides along the outer wall of the third slider 188. At this time, the corrugated telescopic plate 186 slides upward along the inner wall of the slide groove 5 via the second slider 187, thereby causing the corrugated telescopic plate 186 to be compressed synchronously. When the slide cylinder 14 is not rotating, the corrugated telescopic plate 186 applies a dustproof effect to the lead screw 136 in the inner cavity of the central column 2.

[0032] Working principle: First, the carrier box 17 is completely housed inside the box body 6. The first slider 16 is located at the initial end of the first arc groove 3 near the inner side of the box body 6, so that its slide cylinder 14 is fitted onto the bottom of the inner cavity of the central column 2. The second arc groove 15 at its top and the third slider 188 at the bottom of the corrugated telescopic plate 186 are in the initial contact position, so that there is no equipment placed in the trigger components 18 inside the carrier box 17, so that the spring 185 is in a naturally extended state. The silicone sleeve 182 is pushed up by the spring 185, so that the striker 183 is separated from the sensor 184, so that the sensor 184 transmits the no-equipment signal to the indicator light 10 and the display screen 11, so that the indicator light 10 lights up red, and the display screen 11 displays the empty number mark corresponding to the multiple trigger components 18 to represent triggering. Component 18 contains no equipment. When staff need to retrieve or place equipment, they open the sealing cover 12 and press the start button 8 on the outer wall of the housing 6. This start button 8 sends a start signal to the motor 131, causing the outer edge of the output shaft of the motor 131 to drive the worm gear 133 to rotate via the coupling 132. Because the outer spiral edge of the worm gear 133 interlocks with the outer teeth of the worm wheel 135, the worm gear 133 drives the worm wheel 135 to rotate. This rotation causes the rotating shaft 134, which is fixedly sleeved on the inner wall of the worm wheel 135, to rotate. The rotation of the rotating shaft 134 drives the lead screw 136, which is fixedly mounted at the top, to rotate. Because the threads on the inner wall of the slide cylinder 14 interlock with the threads on the outer wall of the lead screw 136, the slide cylinder 14 rotates. The cylinder 14, due to the rotation of the lead screw 136, first drives the first slider 16 to turn through the first arc groove 3, thereby causing the bearing box 17 to synchronously turn 90 degrees from the inner cavity of the box 6 to the outside of the equipment. At this time, after the first slider 16 slides to one end, the cylinder 14, through the lead screw 136, drives the first slider 16 to slide upward along the inner wall of the central column 2. At the same time, the second arc groove 15 rotates synchronously with the rotation of the cylinder 14, causing the rotating second arc groove 15 to slide along the outer wall of the third slider 188. At this time, the corrugated expansion plate 186 slides upward along the inner wall of the slide groove 5 through the second slider 187, thereby causing the corrugated expansion plate 186 to synchronously... Compression is performed, and then the sliding first slider 16 synchronously drives the carrier box 17 to move upward. After the carrier box 17 is raised to a suitable position for easy loading and unloading of equipment, the stop button 9 is pressed, causing the motor 131 to stop running immediately. Utilizing the mechanical self-locking characteristics of the worm gear 133 and worm wheel 135, the lead screw 136 stops rotating, allowing the slide cylinder 14 and carrier box 17 to remain stably at the target height, preventing accidental slippage. At this time, the testing equipment is placed on top of the silicone sleeve 182, which protects and wraps the testing equipment due to its own characteristics. Furthermore, the silicone sleeve 182 will slide against the inner wall of the second square groove 181 due to the weight of the testing equipment itself. This sliding will synchronously drive the spring 185 at the bottom to compress.This causes the striker 183, which is fixedly mounted at the bottom, to slide closer to the sensor 184. When the striker 183 contacts the sensor 184, the sensor 184 sends a conversion signal to its indicator light 10, causing the indicator light 10 to change from red to green. This alerts the operator that the trigger component 18 has stored the corresponding detection equipment. Then, Ou Chen presses the start button 8, which restarts the motor 131. At this time, the output shaft of the motor 131 drives the worm gear 133 to rotate in the opposite direction through the coupling 132, causing the lead screw 136 to rotate in the opposite direction as well. This causes the slide cylinder 14 to first drive the first slider 16 along the guide groove. The inner wall of slide cylinder 4 slides downwards, lowering its carrying box 17 to its initial height, causing the first slider 16 to return to the end of the first arc-shaped groove 3, allowing it to continue reverse transmission. Slide cylinder 14 drives the first slider 16 to slide in the reverse direction along the inner wall of the first arc-shaped groove 3, causing its carrying box 17 to simultaneously rotate back along the first square groove 7 to the inner cavity of the box 6. When the first slider 16 returns to the initial end of the first arc-shaped groove 3, and its carrying box 17 is fully retracted, press the stop button 9 to stop the motor 131. At this time, the corrugated telescopic plate 186 naturally extends with the reset of slide cylinder 14, completely covering the lead screw 136 again, maintaining the dustproof seal of the inner cavity of the central column 2, thus completing the retraction of the testing equipment.
