Description

Technical Field

[0001] This utility model relates to the field of sample storage technology, and in particular to a refrigerated slide storage box. Background Technology

[0002] In the field of sample storage technology, especially in the storage and transportation of endocrinology slide samples, existing storage devices have significant limitations. Traditional storage boxes typically have fixed-size limiting holes inside for inserting test tubes containing samples, and then the box is sealed with a lid to complete the storage. However, in practical applications, endocrinology samples are diverse, and the corresponding test tube sizes (diameter, length) vary considerably. The fixed limiting holes cannot accommodate test tubes of different specifications, resulting in multiple sets of samples from the same patient needing to be stored in separate boxes. This not only increases storage space usage but also easily leads to sample confusion, causing inconvenience for subsequent testing. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a refrigerated slice storage box.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a refrigerated slice storage box, comprising a storage box, the top of which is rotatably connected to a top cover in the vertical direction; universal wheels are provided at the four corners of the bottom of the storage box; a retractable drag bar is provided on one side wall of the storage box in the vertical direction, and the drag bar is equipped with a limit buckle to limit its extension and retraction; shoulder straps are symmetrically provided on both outer walls of the storage box, and the two ends of the shoulder straps are respectively fixed to the side walls of the storage box for diagonally crossing the storage box over the user's shoulders; an adjustment device is provided inside the storage box in the horizontal direction; and a support device is provided at the bottom of the storage box in the vertical direction. The adjusting device includes a connecting rib, which is horizontally fixed between the inner walls of opposite sides of the storage box along the width direction. Slides are provided on both sides of the connecting rib along its length direction. A bracket is fixed on the inner wall of the slide away from the center of the connecting rib. The bracket extends along the length direction of the slide. A sliding rod is rotatably connected to the side of the bracket away from the inner wall of the slide through a shaft in the horizontal direction. The sliding rod extends in a direction perpendicular to the bracket. A movable rod is slidably sleeved on the outer circumference of the sliding rod. The movable rod can move closer to or away from the bracket along the length direction of the sliding rod. Arc-shaped clamps are fixed on the sides of the movable rod opposite to the bracket. The concave surfaces of the two arc-shaped clamps are arranged opposite each other.

[0005] Preferably, each of the arc-shaped clips has a rubber strip fixed to its concave surface. The rubber strip extends along the arc of the arc-shaped clip. A rubber strap is fixed to the edge of the concave surface of one arc-shaped clip. The other end of the rubber strap is fixed to the edge of the concave surface of the other arc-shaped clip. When the two arc-shaped clips move relative to each other, the rubber strap can deform with them and fit against the outer periphery of the test tube.

[0006] Preferably, a damping column is fixed along the length of the slide bar on the side of the bracket facing the movable rod. The free end of the damping column is fixed to the side of the movable rod facing the bracket. A spring is sleeved on the outer periphery of the damping column. One end of the spring is fixed to the side of the bracket, and the other end is fixed to the side of the movable rod. When the movable rod slides away from the bracket along the slide bar, the damping column contracts accordingly, and the spring is compressed synchronously.

[0007] Preferably, a positioning groove is provided on the side of the movable rod away from the arc-shaped clamp along its length. The inner wall of the positioning groove and the outer circumference of the slide rod are respectively provided with pin holes. The movable rod is fixed in position by inserting a fixing pin into the pin hole. When the test tube is placed between the two arc-shaped clamps, the movable rod and the bracket are pressed to bring them closer together. The first damping column retracts and the first spring is compressed. The slide rod slides along the inner wall of the positioning groove. After the rubber strap and the arc-shaped clamp are attached to the outer circumference of the test tube and squeezed and fixed, the fixing pin is passed through the pin holes of the movable rod and the slide rod to lock the distance between the bracket and the movable rod.

[0008] Preferably, the support device includes a square tray, which is vertically slidably connected along the inner wall of the storage box. A sponge pad is fixed to the top of the square tray, and slots are evenly provided on the top of the sponge pad along its length. The slots correspond one-to-one with the positions of the arc-shaped clips and are used to support the bottom of the test tube.

[0009] Preferably, the bottom four corners of the square tray are fixed with a second damping column in the vertical direction. The bottom end of the second damping column is fixed to the inner bottom of the storage box. A second spring is sleeved on the outer periphery of the second damping column. One end of the second spring is fixed to the inner bottom of the storage box, and the other end is fixed to the bottom of the square tray. When the square tray slides down along the inner wall of the storage box, the second damping column contracts, and the second spring is compressed simultaneously.

[0010] Preferably, a snap-fit ​​groove is provided on one side wall of the storage box in the vertical direction, and a connecting block is slidably connected to the inner wall of the snap-fit ​​groove. One end of the connecting block extends into the interior of the storage box and is fixed to one side of the square tray. The connecting block can slide vertically along the inner wall of the snap-fit ​​groove and drive the square tray to move synchronously.

[0011] Preferably, a threaded post is fixed to the top of the inner wall of the snap-fit ​​groove. The threaded post penetrates the connecting block vertically and extends to the bottom of the snap-fit ​​groove. A threaded sleeve is threaded around the outer periphery of the threaded post. The threaded sleeve is located above the connecting block. When the threaded sleeve is rotated to move vertically downward along the threaded post, it can squeeze the connecting block and restrict its position in the snap-fit ​​groove. Beneficial effects

[0012] In this invention, the relative sliding of the sliding bar and the moving bar in the adjusting device, and the elastic cooperation of the spring and the damping rod, can flexibly adjust the spacing of the arc-shaped clamping piece to adapt to test tubes of different diameters. This solves the problem that traditional fixed limiting holes cannot be compatible with multiple specifications of samples, and enables centralized storage of multiple types of test tubes in the same storage box, reducing the hassle of storing samples in separate boxes.

[0013] The rubber strips and rubber straps of the arc-shaped clamp can fit tightly against the outer circumference of the test tube, increasing friction and restricting the rotation of the test tube; the sponge block and notch of the support device can flexibly support the bottom according to the length of the test tube, and with the buffering effect of the spring, effectively prevent the test tube from shaking or colliding during transportation, reducing the risk of sample leakage or damage.

[0014] The adjustment device quickly locks the clamping distance with a pin, and the support device conveniently fixes the height with a threaded ring. The overall structure is simple to operate and adapts to the needs of medical staff for quick sample storage and retrieval. The combination design of bottom moving wheels, retractable pull rod and shoulder strap meets various mobile scenarios such as single-person pushing and pulling, and diagonal carrying, improving the flexibility of transportation.

[0020] Example 1, such as Figure 1-4As shown, a refrigerated slice storage box includes a storage box 1, the main body of which is a rectangular hollow structure, injection molded from food-grade PP material, with a polyurethane insulation layer attached to the inner wall. It can be used with a built-in ice box for refrigeration (the refrigeration function is achieved using existing technology, which will not be elaborated here). The top cover 2 is made of PP material matching the storage box 1 and is vertically connected to the storage box 1 via three stainless steel hinges that rotate along the rear edge of the top. A silicone sealing strip is embedded in the contact surface between the top cover 2 and the storage box 1, which enhances the seal when closed and reduces internal cold loss. Four casters 3 are bolted to the four corners of the bottom of the storage box 1. These are polyurethane wheels with brakes; when braked, they restrict the sliding of the storage box 1, and when unlocked, they allow for 360° rotation. The tow bar 4 is located in the middle of the rear outer wall of the storage box 1. It is a three-section telescopic sleeve structure (made of aluminum alloy). The top of the tow bar 4 has a rubber handle, and the middle is equipped with a spring-loaded buckle. Pressing the buckle adjusts the telescopic state of the tow bar 4, and releasing it automatically locks it. The shoulder straps 5 are symmetrically located on the left and right outer walls of the storage box 1. They are made of nylon webbing, and both ends are connected to the hanging rings on the side walls of the storage box 1 by metal hooks. The middle of the shoulder strap 5 has a plastic adjustment buckle, which can slide along the length of the shoulder strap 5 to adjust the effective length of the shoulder strap 5, making it convenient for the user to carry it diagonally.

[0021] like Figure 2 , Figure 3As shown, the adjustment device is horizontally installed inside the storage box 1 to clamp and fix test tubes of different diameters. The connecting ribs 6 are made of rigid PVC with a rectangular cross-section and are horizontally fixed between the inner walls of the left and right sides along the width of the storage box 1. There are three connecting ribs 6, spaced apart vertically, and they are fixed to the inner wall of the storage box 1 with bolts to form a three-layer storage space. The slides 7 are located on the left and right sides of the connecting ribs 6 and extend along the length of the connecting ribs 6. They have a T-shaped cross-section. Adjustment components are symmetrically installed in the slides 7 on both sides of each connecting rib 6, with adjacent adjustment components spaced apart. Each connecting rib 6 can have 5 sets of adjustment components on one side. The bracket 8 is an L-shaped steel plate. The horizontal section is fixed to the inner wall of the slide 7 away from the center of the connecting rib 6 with bolts, and the vertical section extends into the storage box 1 to support the slide rod 9 and related components. The slide rod 9 is a cylindrical stainless steel rod that is rotatably connected to the vertical section of the bracket 8 in the horizontal direction through a stainless steel shaft. The movable rod 10 is a hollow stainless steel tube, which slides smoothly along the outer periphery of the slide rod 9, allowing it to move closer to or further away from the bracket 8. The arc-shaped clamping pieces 12 are made of ABS plastic and are fixed to the sides of the movable rod 10 and the bracket 8 opposite each other (i.e., the side of the movable rod 10 closest to the bracket 8, and the side of the bracket 8 closest to the movable rod 10), with the concave surfaces of the two arc-shaped clamping pieces 12 facing each other. Silicone strips are adhered to the concave surfaces of the arc-shaped clamping pieces 12, extending along the curvature of the clamping pieces 12 to increase friction with the test tube. A rubber strap 11 (made of natural rubber) is fixed to the upper and lower edges of the concave surface of one arc-shaped clamping piece 12, with the other end fixed to the corresponding edge of the other arc-shaped clamping piece 12. When the two arc-shaped clamping pieces 12 approach each other, the rubber straps 11 deform according to the diameter of the test tube and conform to the outer periphery, enhancing clamping stability. The first damping column 14 is a hydraulic damping rod, with one end fixed to the side of the vertical section of the bracket 8 by a screw, and the other end fixed to the side of the movable rod 10. The first spring 15 is a cylindrical helical spring, sleeved on the outer periphery of the first damping column 14, with both ends abutting against the sides of the bracket 8 and the movable rod 10 respectively. When the movable rod 10 moves away from the bracket 8, the first damping column 14 retracts, the first spring 15 is compressed and generates a restoring force, driving the movable rod 10 closer to the bracket 8, so that the arc-shaped clamp 12 clamps the test tube. The positioning groove 16 is opened on the side of the movable rod 10 away from the arc-shaped clamp 12, extending along the length of the movable rod 10. The inner wall of the positioning groove 16 has corresponding pin holes on the outer periphery of the slide rod 9. Three pin holes are spaced apart along the length of the slide rod 9 to accommodate the clamping requirements of test tubes of different diameters. The fixing pin 17 is made of stainless steel, with a circular grip at one end and a tapered guide head at the other end, which can be inserted into the pin hole to fix the relative position of the movable rod 10 and the slide rod 9.

[0022] The working process of the regulating device:

[0023] When placing the test tube, first pull the movable rod 10 to slide it away from the bracket 8 along the slide rod 9. At this time, the first damping column 14 retracts and the first spring 15 is compressed. After the positioning groove 16 is aligned with the pin hole of the slide rod 9, insert the fixing pin 17 to temporarily lock it. Place the test tube between the two arc-shaped clamps 12, remove the fixing pin 17, and the first spring 15 resets and drives the movable rod 10 to approach the bracket 8, so that the rubber strip of the arc-shaped clamp 12 fits the outer circumference of the test tube. The rubber strap 11 deforms and tightens with the diameter of the test tube. After the clamping is stable, insert the fixing pin 17 again through the corresponding pin hole to lock the position of the movable rod 10 and complete the fixation of the test tube.

[0024] like Figure 4 As shown, the support device is vertically positioned at the bottom of the storage box 1 to support the bottom of the test tubes and accommodate test tubes of different lengths. The square tray 18 is made of PP material, its dimensions match the internal cross-section of the storage box 1, and its edges are integrally formed with sliders that slide in conjunction with the vertical grooves on the inner wall of the storage box 1, allowing it to slide up and down vertically. The sponge pad 19 is made of high-density polyurethane sponge and is glued to the top of the square tray 18. The slot 20 is a semi-circular groove evenly spaced along the length of the sponge pad 19, corresponding one-to-one with the arc-shaped clips 12 of the adjustment device (coaxial top and bottom), used to embed into the bottom of the test tubes to prevent them from shaking. The second damping column 21 is a hydraulic damping rod, which is fixed to the four bottom corners of the square support plate 18 by bolts. The bottom end of the second damping column 21 is fixed to the bottom of the storage box 1. The second spring 22 is a cylindrical helical spring, which is sleeved on the outer periphery of the second damping column 21. Its two ends abut against the bottom of the storage box 1 and the bottom of the square support plate 18, respectively. In its natural state, it can lift the square support plate 18 upward. The snap-fit ​​groove 23 is opened in the middle of the right side wall of the storage box 1, extends vertically, and has a rectangular cross-section. The connecting block 25 is made of PP material. One end is fixed to the right side wall of the square support plate 18 by screws, and the other end extends through the snap-fit ​​groove 23 to the outside of the storage box 1. It can slide vertically along the inner wall of the snap-fit ​​groove 23 with the square support plate 18. The threaded post 24 is made of stainless steel and is fixed vertically to the inner wall of the snap-fit ​​groove 23. Its top end is flush with the top of the snap-fit ​​groove 23 and its bottom end extends to the bottom of the snap-fit ​​groove 23. The threaded post 24 passes through the through hole in the middle of the connecting block 25 and is fitted with the through hole with a clearance, allowing the connecting block 25 to slide along the threaded post 24. The threaded sleeve 26 is made of nylon and has an internal thread on its inner circumference that matches the threaded post 24. It has anti-slip ridges on its outer circumference and is fitted on the outer circumference of the threaded post 24 and located above the connecting block 25. The threaded sleeve 26 can be rotated to move vertically along the threaded post 24.

[0025] The working process of the support device:

[0026] When adjusting the support height according to the test tube length, first rotate the threaded sleeve 26 clockwise to move it upward along the threaded post 24, releasing the pressure on the connecting block 25. The square support plate 18 slides upward under the elastic force of the second spring 22, driving the sponge pad 19 closer to the adjustment device, aligning the bottom of the test tube with the corresponding slot 20. The test tube's own weight presses down on the square support plate 18, causing the second damping post 21 to contract and the second spring 22 to compress until the bottom of the test tube is completely embedded in the slot 20. Finally, rotate the threaded sleeve 26 counterclockwise to move it downward, pressing the top of the connecting block 25, locking the position of the square support plate 18, and completing the bottom support of the test tube.

[0027] Working principle: Open the top cover 2, unlock the fixing pin 17 of the adjustment device, pull the movable rod 10 to open the arc-shaped clamp 12, insert the fixing pin 17 for temporary fixation, place the test tube containing the slide between the two arc-shaped clamps 12, remove the fixing pin 17, use the elastic force of the No. 1 spring 15 to clamp the test tube with the arc-shaped clamp 12 and the rubber strap 11, then insert the fixing pin 17 to lock, loosen the threaded sleeve 26, let the square tray 18 descend to the appropriate height under the weight of the test tube, lock the threaded sleeve 26 to fix, put in the ice box (or start the refrigeration module), close the top cover 2, and move the storage box 1 by the universal wheels 3, the tow bar 4 or the shoulder strap 5 to complete the cold storage and transportation of the slide sample.
