Description

Technical Field

[0001] This utility model relates to the field of stacking barrel technology, specifically a sealed stacking barrel structure for cold chain logistics. Background Technology

[0002] Stacking drums are used in cold chain logistics to transport frozen foods and fresh agricultural products. Existing stacking drums, such as the one disclosed in authorization notice number CN220333338U, include at least a drum body, a handle fixed to the top of the drum body, and a lid threadedly connected to the top of the drum body, which serves to seal the stacking drum.

[0003] However, during the transportation of cold chain products, when subjected to vibration or collision, the sealing cap is prone to loosening, which in turn causes the cold chain products to come into contact with the outside air, resulting in damage to the quality of the cold chain products inside the container and rendering them inedible, thus causing significant losses. Therefore, when dealing with cold chain logistics, higher requirements are needed for the stability of the container lids of stacked containers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a sealed stacking barrel structure for cold chain logistics, solving the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealed stacking barrel structure for cold chain logistics, comprising a barrel body, a groove on the top of the barrel body, an integrally formed mounting ring communicating with the inner cavity of the barrel on the groove, an integrally formed pipe opening on the top of the mounting ring, and a sealing cap connected to the upper part of the outer wall of the pipe opening by threads; a fixing ring integrally formed on the outer wall of the sealing cap, the fixing ring having uniformly circumferentially formed through holes, a lifting structure on the top of the mounting ring for lifting a connecting ring, and an integrally formed insert tube on the top of the connecting ring, with several insert tubes inserted into several through holes respectively.

[0006] Preferably, the lifting structure includes a guide rod and a support spring disposed on the mounting ring. The guide rod extends vertically through the connecting ring and fits against the inner wall of the insertion tube. The top of the support spring is connected to the connecting ring.

[0007] Preferably, both ends of the connecting ring are connected by connecting rods, and both connecting rods are connected to pull rods. An arc-shaped rod is fixedly connected to the connecting rod, and an arc-shaped anti-slip pad is adhered to the arc-shaped rod. The arc-shaped anti-slip pad is located between the tube opening and the connecting ring. A connecting spring is connected to the pull rod, and the connecting spring is connected to the connecting ring.

[0008] Preferably, the outer wall of the pipe opening is integrally formed with at least two convex rings, and the outer wall of the pipe opening is also fitted with an anti-slip sleeve that is fitted outside the two convex rings, and the arc-shaped anti-slip pads around the pipe opening are all in close contact with the anti-slip sleeve.

[0009] Preferably, the outer wall of the pipe opening is also integrally formed with a stop that fits against the bottom of the sealing cap, the arc-shaped anti-slip pad and the anti-slip sleeve are both located below the stop, and the inner diameter of the connecting ring is larger than the outer diameter of the stop.

[0010] Preferably, the through hole is a waist-shaped hole, and a handle is integrally formed in the groove. The top and bottom sides of the barrel are respectively integrally formed with a protrusion and a recess.

[0011] This invention provides a sealed stacking drum structure for cold chain logistics. Compared with the prior art, it has the following advantages:

[0012] 1. This sealed stacking drum structure for cold chain logistics features a fixing ring with evenly spaced through holes on the outer wall of the sealing cap. A lifting mechanism raises and lowers the connecting ring, allowing several tubes on the connecting ring to be inserted into the through holes. Since the tubes cannot rotate, when the sealing cap is loosened, the through holes of the fixing ring are obstructed by the tubes and cannot rotate. This ensures that even during the transportation of cold chain products, the sealing cap will not loosen or detach, even after prolonged vibration or impact. This guarantees the seal between the sealing cap and the tube opening, better protecting the cold chain products inside the drum.

[0013] 2. This sealed stacking bin structure for cold chain logistics features a lifting mechanism composed of guide rods and support springs. This allows workers to quickly raise and lower the tube by pressing and releasing the connecting ring, saving time and effort. The curved anti-slip pads on the connecting rings increase friction, preventing them from wobbling under vibration. The connecting springs allow the curved anti-slip pads to be opened, reducing resistance when workers raise and lower the connecting rings. The anti-slip sleeves, through their elasticity, maintain close contact with the curved anti-slip pads when the connecting springs move back and forth, further ensuring the stability of the connecting rings under vibration. This improves the stability of the tube insertion and enhances the stability of the sealing cap. Attached Figure Description

[0019] 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.

[0020] See Figures 1-4 This utility model provides the following three technical solutions:

[0021] First implementation: A sealed stacking barrel structure for cold chain logistics includes a barrel body 1. A groove 2 is provided on the top of the barrel body 1. An installation ring 3 is integrally formed on the groove 2, communicating with the inner cavity of the barrel body 1. A pipe opening 4 is also integrally formed on the top of the installation ring 3. A sealing cap 5 is connected to the upper part of the outer wall of the pipe opening 4 by threads. When the sealing cap 5 is screwed on the pipe opening 4, no matter where it is screwed in from, the position of the sealing cap 5 is the same after it is finally tightened. This can be achieved using existing threaded connection technology to ensure that the subsequent insertion tube 9 can be inserted into the through hole 7.

[0022] In order to move, a handle 20 is integrally formed in the groove 2. In order to stack, a protrusion 21 and a recess 22 are integrally formed on the top and bottom sides of the barrel body 1, respectively.

[0023] The outer side of the sealing cap 5 is also provided with anti-slip protrusions, and the inside is also provided with a sealing ring for sealing;

[0024] The outer wall of the sealing cap 5 is also integrally formed with a fixing ring 6. The fixing ring 6 has through holes 7 evenly circumferentially opened. The top of the mounting ring 3 is provided with a lifting structure, which is used to lift the connecting ring 8. The top of the connecting ring 8 has an insert tube 9 evenly circumferentially formed. Several insert tubes 9 are inserted into several through holes 7 respectively. Since the insert tubes 9 cannot rotate, when the sealing cap 5 is loosened, the through holes 7 of the fixing ring 6 will be obstructed by the insert tubes 9 and cannot rotate. Thus, even if the cold chain products are subjected to vibration or collision for a long time during transportation, the sealing cap 5 will not loosen or fall off, thereby ensuring the seal between the sealing cap and the pipe opening and better protecting the cold chain products in the container.

[0025] Among them, the through hole 7 is an oblong hole. When tightening the sealing cap 5, it is difficult to ensure that the position is exactly the same every time it is installed. If a matching round hole is used, it is often necessary to rotate the sealing cap again to make the through hole 7 completely aligned with the insertion tube 9, which is quite troublesome. Therefore, by using an oblong hole that is slightly larger than the insertion tube 9, as long as the oblong hole can be aligned with the insertion tube 9 when tightening, it can not only ensure that it is not loose, but also improve the operating efficiency.

[0026] The lifting structure includes a guide rod 10 and a support spring 11 mounted on the mounting ring 3. The guide rod 10 extends vertically through the connecting ring 8 and fits against the inner wall of the insertion tube 9. The top of the support spring 11 is connected to the connecting ring 8. The guide rod 10 guides the connecting ring 8 and the insertion tube 9. The support spring 11 is used to lift the connecting ring 8 to ensure the height of the insertion tube 9. Workers can quickly lift and lower the insertion tube 9 by pressing and releasing the connecting ring 8, saving time and effort.

[0027] Although using the support spring 11 saves time and effort, the support spring 11 has a resonance problem during vibration, which will cause the insertion tube 9 to sway back and forth, and may cause it to disengage from the through hole 7. Therefore, a connecting rod 13 is inserted through both ends of the connecting ring 8, and a pull rod 12 is connected to both sides of the connecting rod 13. An arc-shaped rod 14 is fixedly connected to the connecting rod 13, and an arc-shaped anti-slip pad 15 is glued to the arc-shaped rod 14. The arc-shaped anti-slip pad 15 is located between the tube opening 4 and the connecting ring 8. In order to avoid the arc-shaped anti-slip pad 15 obstructing the connection ring 8 when the worker raises and lowers it, a connecting spring 16 is connected to the pull rod 12. The connecting spring 16 is connected to the connecting ring 8, so that the pull rod 12 can move laterally.

[0028] The connecting ring 8, through the friction of the arc-shaped anti-slip pad 15, can play a role in damping and preventing the insertion tube 9 from swaying back and forth when the supporting spring 11 resonates.

[0029] The second implementation differs from the first in that, in order to make it easier for workers to move the connecting ring 8 up and down, a connecting spring 16 is provided. However, this can cause the arc-shaped anti-slip pad 15 to wobble back and forth. Therefore, at least two protruding rings 17 are integrally formed on the outer wall of the pipe opening 4. An anti-slip sleeve 18 is also fitted onto the outer wall of the pipe opening 4 and fitted onto the outside of the two protruding rings 17. The protruding rings 17 are used to position the anti-slip sleeve 18 so that the arc-shaped anti-slip pads 15 around the pipe opening 4 are all in close contact with the anti-slip sleeve 18. When the connecting spring 16 causes the arc-shaped anti-slip pad 15 to wobble back and forth, the anti-slip sleeve 18 can maintain its contact with the arc-shaped anti-slip pad 15 through its own elastic expansion and contraction, thereby ensuring the friction force on the connecting ring 8.

[0030] The third implementation method differs from the second implementation method in that a stop 19 is integrally formed on the outer wall of the pipe opening 4 to fit the bottom of the sealing cover 5, which is used to stop the installation of the sealing cover 5. The arc-shaped anti-slip pad 15 and the anti-slip sleeve 18 are both located below the stop 19, and the inner diameter of the connecting ring 8 is larger than the outer diameter of the stop 19, so that the connecting ring 8 can be installed through the outside of the stop 19.

[0031] Both the support spring 11 and the connecting spring 16 mentioned in the text can be installed by means of hook connection, just like a tension spring.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] When subjected to vibration or impact, the sealing cap 5 is unable to be loosened by passing through the insertion tube 9 through the through hole 7, thus reinforcing the sealing cap 5 and ensuring its seal with the tube opening 4. The connecting ring 8 is tightly fitted with the anti-slip sleeve 18 through the arc-shaped anti-slip pad 15, providing resistance to the connecting ring 8 and making it difficult for the insertion tube 9 to shake up and down and disengage from the through hole 7. When the worker needs to open the sealing cap 5, he pulls the lever 12 to both sides to disengage the arc-shaped anti-slip pad 15 from the anti-slip sleeve 18, and then presses the lever 12 down to make the connecting ring 8 drive the insertion tube 9 downward to disengage from the through hole 7. At this time, one hand can hold the lever 12 on one side while the other hand loosens the sealing cap 5.
