Description

Technical Field

[0001] This utility model relates to the field of transport liquid bags, specifically to a transport liquid bag with a quick loading and unloading interface. Background Technology

[0002] Liquid transport bags are a modern and efficient flexible bulk liquid transport tool. They are usually made of multi-layer composite flexible materials and are characterized by light weight, foldability, and low storage and transportation costs. Compared with traditional iron drums or IBC containers, liquid bags can be placed on standard containers, trucks, or railway freight cars for transportation, which greatly increases the single load capacity and reduces packaging costs. They are particularly suitable for long-distance and even international trade of non-hazardous liquid food, chemicals, and vegetable oils. After use, liquid bags can be recycled or discarded, reducing storage and waste disposal space and costs, and providing an economical and environmentally friendly solution for liquid logistics. Current transport bags for liquids still have the following problems: The interfaces of these devices generally use traditional threaded or flanged connections. Whether tightening the threads one turn at a time or symmetrically securing multiple bolts on the flange, the process is extremely tedious and time-consuming. This not only tests the physical strength of the operators but also heavily relies on specialized wrenches, significantly impacting loading and unloading efficiency. Furthermore, the sealing performance is highly dependent on the precision of human operation. If the tightening torque is uneven or insufficient, the built-in rubber sealing ring is prone to displacement, twisting, or even crushing, leading to a poor seal. During long-distance transportation, continuous vibration and impact can further loosen the already unevenly stressed connection points, causing the sealing ring to fail and resulting in liquid leakage, causing economic losses, environmental pollution, and even safety hazards. Therefore, those skilled in the art provide a transport liquid bag with a quick-loading interface to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this invention is to provide a transport liquid bag with a quick loading and unloading interface, which solves the problem of low loading and unloading efficiency of the transport liquid bag interface in the prior art, which easily leads to the failure of the sealing ring and thus causes liquid leakage.

[0004] This utility model provides the following technical solution: a transport liquid bag with a quick loading and unloading interface, including a liquid bag body, an interface pipe connected to the drain end of the liquid bag body, a drain hole at the bottom end of the interface pipe, a sealing ring fixedly connected to the outer surface of the interface pipe, a locking mechanism for quickly controlling the sealing and opening of the drain hole between the liquid bag body and the interface pipe, and a switching component for assisting in controlling its drain flow rate inside the interface pipe.

[0005] As a preferred embodiment of the above technical solution, the locking mechanism includes a support tube fixedly connected to the outer surface of the liquid bag body, and the support tube and the interface tube are slidably adapted to each other. The support tube is symmetrically provided with a main slot and a secondary slot inside.

[0006] As a preferred embodiment of the above technical solution, a transfer cylinder is fixedly connected to the outer surface of the support tube, a top column is slidably connected to the center of the transfer cylinder, a limit plate is fixedly connected to the outer surface of the top column, and a second spring is fixedly connected to the bottom end of the limit plate.

[0007] As a preferred embodiment of the above technical solution, the locking mechanism further includes a storage slot formed on the outer surface of the interface tube, a first spring being slidably connected inside the storage slot, an elastic piece being fixedly connected to the inner wall of the storage slot, and a protrusion being fixedly connected to the top of the elastic piece.

[0008] As a preferred embodiment of the above technical solution, the switching component includes a diversion seal plate fixedly connected to the inner wall of the interface tube, and the diversion seal plate has a liquid passage hole inside.

[0009] As a preferred embodiment of the above technical solution, a rotating column is rotatably connected to the center of the diversion sealing plate, and a diversion plate is fixedly connected to one end of the rotating column near the liquid bag body. Multiple diversion holes are opened in the internal circumferential array of the diversion plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a locking mechanism to achieve a fast, reliable, and tool-free drainage operation. The operator simply triggers the locking mechanism, and the pre-compressed elastic element inside instantly releases energy, automatically and quickly switching the sealing state of the drainage hole. This not only greatly improves drainage efficiency and avoids the traditional cumbersome opening and closing steps, but also effectively prevents misalignment or wear of the sealing ring caused by uneven tightening force. As a result, it maintains extremely high sealing reliability even during frequent opening and closing and transportation vibrations, thus preventing leakage risks. At the same time, it reduces the labor intensity of operators and the reliance on professional skills. Attached Figure Description

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0014] Please see Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a transport liquid bag with a quick loading and unloading interface, including a liquid bag body 1, an interface pipe 2 connected to the drain end of the liquid bag body 1, a drain hole 5 opened at the bottom end of the interface pipe 2, a sealing ring 6 fixedly connected to the outer surface of the interface pipe 2, a locking mechanism 3 for quickly controlling the sealing and opening of the drain hole 5 is provided between the liquid bag body 1 and the interface pipe 2, and a switching component 4 for assisting in controlling its drain flow rate is provided inside the interface pipe 2.

[0015] When liquid needs to be discharged from the liquid bag body 1, the locking mechanism 3 is used to switch the sealing and opening states of the drain hole 5 with free elastic force, realizing a fast, reliable, and tool-free draining operation. The operator only needs to trigger the locking mechanism 3, and the pre-pressurized elastic element inside will release energy instantly, automatically and quickly switching the sealing state of the drain hole 5. This not only greatly improves the draining efficiency and avoids the traditional cumbersome opening and closing steps, but also effectively avoids the misalignment or wear of the sealing ring 6 caused by uneven tightening force. Thus, it can maintain extremely high sealing reliability even in frequent opening and closing and transportation vibration, thereby preventing leakage risk and reducing the labor intensity of operators and the dependence on professional skills. Furthermore, when the liquid discharge volume in the liquid bag body 1 needs to be controlled according to the actual situation, the switching component 4 is used to drive the liquid discharged from the liquid bag body 1 to divert and adjust the discharge volume according to the demand, and precisely adjust the opening of the diversion channel, thereby achieving stepless control of the discharge volume. This breaks the traditional "all open and all closed" extensive mode of liquid bag discharge and realizes refined and controllable liquid management. That is, in the case of needing precise metering or small flow of material addition, it can stably provide a small flow of liquid to avoid waste and splashing. When it is necessary to quickly empty the liquid, it can switch to the full-flow state to ensure efficiency. This flexibility and controllability greatly expands the application scenarios of liquid bags, and effectively reduces the potential for spillage, inaccurate metering, and hydraulic shock to downstream equipment caused by flow loss, thereby improving the safety and economy of the entire operation process.

[0016] As one implementation method in this embodiment, please refer to Figure 2 - Figure 4 As shown, the locking mechanism 3 includes a support tube 31 fixedly connected to the outer surface of the liquid bag body 1, and the support tube 31 is slidably adapted to the interface tube 2. The support tube 31 has a main slot 36 and a secondary slot 37 symmetrically opened inside. A transfer cylinder 38 is fixedly connected to the outer surface of the support tube 31. A top post 39 is slidably connected to the center of the transfer cylinder 38. A limiting piece 310 is fixedly connected to the outer surface of the top post 39. A second spring 311 is fixedly connected to the bottom end of the limiting piece 310. The locking mechanism 3 also includes a storage groove 32 opened on the outer surface of the interface tube 2. A first spring 33 is slidably connected inside the storage groove 32. An elastic piece 34 is fixedly connected to the inner wall of the storage groove 32. A protrusion 35 is fixedly connected to the top end of the elastic piece 34.

[0017] When the locking mechanism 3 is driven to control the drain hole 5 to be in the open state, the operator only needs to press down on the top post 39 so that the fixed limiting piece 310 squeezes the first spring 33 against the support tube 31 to retract and avoid it. The displacement of the top post 39 squeezes the protrusion 35, which carries the elastic piece 34, towards the storage groove 32 to fit. At this time, the protrusion 35 disengages from the inside of the main slot 36, and the pressure force of the second spring 311 is released. The rebound of the second spring 311 pushes the interface tube 2 to move horizontally along the support tube 31, so that the protrusion 35 slides into the secondary slot 37, and the drain hole 5 moves away from being blocked by the support tube 31.

[0018] As one implementation method in this embodiment, please refer to Figure 2 - Figure 5As shown, the switching component 4 includes a diversion sealing plate 44 fixedly connected to the inner wall of the interface tube 2, and a liquid passage hole 45 is opened inside the diversion sealing plate 44; a rotating column 42 is rotatably connected to the center of the diversion sealing plate 44, and a diversion plate 41 is fixedly connected to one end of the rotating column 42 near the liquid bag body 1, and a plurality of diversion holes 43 are opened in a circular array inside the diversion plate 41.

[0019] Additional explanation: The feed tube 38 is located directly above the main slot 36. The end of the second spring 311 away from the limiting piece 310 is in contact with the support tube 31. One end of the first spring 33 is in contact with the interface tube 2. The other end of the first spring 33 is in contact with the support tube 31. The diameters of the multiple diversion holes 43 are gradually increased clockwise. When the switching component 4 is driven, the operator only needs to hold the rotating column 42 and rotate it to make the diversion plate 41 carry the multiple diversion holes 43 with different diameters gradually distributed and rotate accordingly. Then, the multiple diversion holes 43 with different diameters overlap with the liquid passage hole 45 to freely control the amount of liquid diverted by the interface pipe 2.

[0020] The working principle is explained mainly by describing the open and closed states for ease of description and understanding: Open state: Personnel need to press down on the top column 39 to fix the limiting piece 310, which will squeeze the first spring 33 against the support tube 31 to retract and avoid it. The displacement of the top column 39 will squeeze the protrusion 35 carrying the elastic piece 34 towards the storage slot 32 to fit. At this time, the protrusion 35 will disengage from the inside of the main slot 36, and the pressure force of the second spring 311 will be released. The rebound of the second spring 311 will push the interface tube 2 to move horizontally along the support tube 31, so that the protrusion 35 will slide into the secondary slot 37. The drain hole 5 will move away from being blocked by the support tube 31. At this time, the liquid in the liquid bag body 1 will be discharged along the interface tube 2 and the drain hole 5. Blocking state: Working backward from the above process, the operator first presses down on the protrusion 35 to disengage it from the secondary slot 37, and then holds the interface tube 2 and pushes it horizontally toward the support tube 31 until the protrusion 35 moves into the interior of the main slot 36. At this time, the sealing ring 6 follows the movement of the interface tube 2 and fits between the support tube 31 and the interface tube 2, while the drain hole 5 is sealed and blocked by the support tube 31.

[0021] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
