Description

Technical Field

[0001] This utility model relates to the field of logistics and transportation technology, and in particular to a cover device and container for a discharge port channel, specifically relating to the dustproof, waterproof and anti-theft functions of the discharge port channel. Background Technology

[0002] With the rapid development of China's economy, the logistics industry has also flourished. Compared to the transportation of general goods, liquid transportation places higher demands on transportation equipment. Generally, packaging capable of storing and transporting various non-hazardous liquids or bulk goods is called a container. Compared to traditional transport packaging methods, it can significantly reduce costs associated with loading, unloading, packaging, transportation, and material management, offering substantial economic advantages. Therefore, it is more widely used in various fields such as chemicals, petroleum, food, feed, and agricultural products.

[0003] When filling a container with liquid, an inner liner bag is required. Therefore, a discharge port needs to be set on the container to facilitate the filling and flowing out of the liquid in the inner liner bag. In order to ensure the dustproof effect and safety performance of the discharge port, a channel cover device is usually set on the discharge port.

[0004] Currently, most common container discharge port cover devices adopt a flip-top design, relying on elasticity to achieve closure or maintain an open state, as disclosed in Chinese invention patent CN202010079132.3 entitled "Container". However, during long-term use, these elastic-based cover devices are prone to incomplete closure upon reset. Furthermore, the cover, connecting device, rotating pin, and elastic components all require additional assembly, making one-piece molding impossible and resulting in high production costs. Existing technologies also utilize magnetic force to achieve closure or maintain an open state; however, this magnetic fixation method may experience a decrease in magnetism due to liquid corrosion or long-term use under certain environments, affecting the cover's fixation. Therefore, this paper proposes a cover device and container for a container discharge port channel. Utility Model Content

[0005] The purpose of this utility model is to provide a cover device and container for a container discharge port channel, thereby solving the technical problems mentioned in the background art of complex structure and low reliability of container discharge port channels.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the components in the drawings may be shown exaggeratedly for illustrative purposes and are not necessarily to scale. In the drawings, the same reference numerals are used for components that are identical or have the same function.

[0032] In this invention, unless otherwise specified, "arranged on," "arranged above," and "arranged on top of" do not exclude the possibility of an intermediate element between them. Furthermore, "arranged on or above" merely indicates the relative positional relationship between two components, and in certain cases, such as when the product orientation is reversed, it can also be converted to "arranged below or under," and vice versa.

[0033] In this utility model, the various embodiments are merely intended to illustrate the solution of this utility model and should not be construed as limiting.

[0034] In this utility model, unless otherwise specified, the quantifiers “one” and “one” do not exclude scenarios involving multiple elements.

[0035] It should also be noted that in the embodiments of this utility model, only a portion of the parts or components may be shown for clarity and simplicity. However, those skilled in the art will understand that, under the teachings of this utility model, the required parts or components can be added according to the specific scenario.

[0036] It should also be noted that within the scope of this utility model, the terms "same," "equal," and "equal to" do not mean that the two values ​​are absolutely equal, but rather allow for a certain reasonable error. That is to say, the terms also cover "substantially the same," "substantially equal," and "substantially equal to." Similarly, in this utility model, the terms indicating direction, such as "perpendicular to" and "parallel to," also cover the meaning of "substantially perpendicular to" and "substantially parallel to."

[0037] This invention is based on the inventor's insight that common container discharge port cover devices employ a flip-top design, using magnetic force to achieve closure or maintain an open state. These magnetically-driven cover devices are fixed by inserting the upper part of the cover plate into a corresponding slot in the base. The cover plate also has a rotatable shaft, and a magnet is mounted on the lower part of the cover plate. Under normal conditions, the rotating shaft is linear. The operator rotates the lower part of the cover plate from bottom to top around the shaft with their finger. When the lower part of the cover plate is against the side plate of the container, the magnet at the lower end of the cover plate attracts the steel pipe inside the container's side plate, preventing it from falling off. At this point, the container's discharge port is open. Moving the lower part of the cover plate with a finger disengages the magnet from the steel pipe, and the lower end of the cover plate rotates around the shaft to close, thus closing the container's discharge port. However, this magnetic fixation method may, under certain conditions, experience a decrease in magnetism due to liquid corrosion or long-term use, affecting the fixation effect on the cover plate.

[0038] The inventors discovered that improving the channel cover device for container discharge ports can be achieved by at least the following aspects: simplifying the structure of the cover device to facilitate easy opening or complete closing, and improving the stability of the cover when closed. Based on this, the inventors propose a new channel cover device for container discharge ports. The cover plate has a first rotating shaft and a second rotating shaft, allowing for two-fold opening or closing of the discharge port channel. Two symmetrical protrusions are arranged on both sides of the lower end of the cover plate, engaging with grooves on the discharge port channel to keep the cover plate in the open position. A hook is provided on the lower inner side of the cover plate, which can be fastened to the ribs at the lower part of the discharge port channel, ensuring the cover plate remains closed when closed. Furthermore, the cover plate and container are locked using straps or similar binding methods, improving the safety and stability of goods during packaging and transportation. This invention provides a cover device for a container discharge port channel and a container that is simple to operate, easy to replace parts, reduces maintenance costs, and effectively prevents dust and theft.

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] like Figures 1-6 As shown, a cover device for a container discharge port channel includes a discharge port channel 002 and a cover plate 001 disposed at the outer end of the discharge port channel 002. The discharge port channel is disposed on the container base and is used for filling and / or discharging goods inside the container.

[0041] The upper part of the cover plate 001 is fixedly connected to the upper part of the discharge port channel 002; a first rotating shaft portion 101 is provided in the middle of the cover plate 001, and a second rotating shaft portion 102 is provided near the upper end of the cover plate 001. In this embodiment, the first rotating shaft portion 101 and the second rotating shaft portion 102 are relatively thin and have a certain degree of flexibility, so that the portions of the cover plate 001 located on both sides of the first rotating shaft portion 101 can be flipped relative to each other; the portions of the cover plate 001 located on both sides of the second rotating shaft portion 102 can also be flipped relative to each other.

[0042] The discharge port channel 002 has two symmetrically arranged grooves 206 in the middle, and the cover plate 001 has two symmetrically arranged protrusions 106 at the lower end for engaging with the two grooves 206 respectively.

[0043] like Figure 2 This diagram illustrates the open state of a container discharge port cover device according to an embodiment of the present invention. When opening the cover plate on the discharge port channel, the operator inserts their fingers into the locking hole 208 of the base, presses against the lower part of the cover plate 001, and lifts it upwards. The parts of the cover plate located on both sides of the first rotating shaft 101 flip relative to each other, and the parts of the cover plate located on both sides of the second rotating shaft 102 flip relative to each other. After being lifted to a certain height, the two protrusions 106 at both ends of the lower part of the cover plate are fastened and engaged into the grooves 206 of the base. At this time, the parts of the cover plate located on both sides of the first rotating shaft are almost flat, and the parts of the cover plate located on both sides of the second rotating shaft form a certain angle. Under the effect of its own weight and the limiting cooperation of the grooves and protrusions, the cover plate remains in the open position of the channel.

[0044] Figure 3 The diagram shows a discharge port channel of a container discharge port cover device according to an embodiment of the present invention. As shown in the figure, the discharge port channel 002 includes a recessed platform 201 disposed on the container base. The recessed platform 201 has a surrounding edge 202 for accommodating the cover plate 001. The surrounding edge protects the cover plate from protruding when closed, preventing damage from external objects. Two grooves 206 are disposed on both sides of the recessed platform 201 near the upper end, and the cross-section of the grooves 206 is acute-angled, which facilitates the insertion of the cover plate protrusion 106 while also providing a good limiting effect.

[0045] The upper outer side of the sinking platform 201 near both ends is provided with square holes 203. The upper inner side of the cover plate 001 near both ends is provided with two spring buckles 103 that respectively engage with the two square holes 203. The two square holes 203 on the sinking platform 201 can be inserted into the two spring buckles 103 on the cover plate 001 respectively, further improving the fixed connection effect between the upper part of the cover plate and the discharge port channel.

[0046] The upper outer side of the recessed platform 201 has a slot 204 in the middle, and the bottom of the slot 204 has a protruding structure that can be inserted and cooperated with the limiting part 104 of the cover plate 001.

[0047] The recessed platform 201 has two first ribs 205 respectively located between the slot 204 and the two square holes 203.

[0048] The lower outer side of the recessed platform 201 is symmetrically provided with two pairs of ribs 207 with grooved structures, which can cooperate with the hooks 107 of the cover plate 001.

[0049] The lower part of the recessed platform 201 has a locking hole 208 between the two pairs of ribs 207, which can be engaged with the cable tie hole 108 on the cover plate 001.

[0050] Figures 4-5 The figures show the front and back structural diagrams of a channel cover device for a container discharge port according to an embodiment of the present invention. As shown, the cover 001 mainly includes a first rotating shaft portion 101, a second rotating shaft portion 102, a spring buckle 103, a limiting portion 104, and a protrusion 106, and is disposed at the outer end of the discharge port channel. Spring buckles 103 are provided at both ends of the upper inner side of the cover 001, which can be fastened into the square holes 203 on both sides of the upper part of the discharge port channel, thus limiting the cover. A limiting portion 104 is provided in the middle of the upper inner side of the cover 001, and the limiting portion 104 is U-shaped. The first rotating shaft portion 101 is provided in the middle of the cover 001, and the portions on both sides of the first rotating shaft portion 101 can be flipped relative to each other. The second rotating shaft portion 102 is provided near the upper end of the cover 001, and the portions on both sides of the second rotating shaft portion 102 can be flipped relative to each other. The cover plate 001 has two symmetrical protrusions 106 on both sides of its lower end, which engage with the grooves 206 on the discharge port channel, allowing the cover plate to remain in the open state. A second rib 105 is provided on the upper inner side of the cover plate 001. A hook 107 is provided on the lower inner side of the cover plate 001, which can be fastened to the rib 207 at the lower part of the discharge port channel, allowing the cover plate 001 to remain in the closed state. When the cover plate 001 is closed, there is a gap between the middle of its lower end and the bottom surface of the locking hole 208. The cover plate 001 also has a cable tie hole 108, and the base has a locking hole 208. The cover plate 001 can be fixedly connected to the discharge port channel 002 by a cable tie passing through the cable tie hole 108 and the locking hole 208. The cable tie secures the cover plate and container, improving the safety and stability of goods during packaging and transportation.

[0051] Figure 6This diagram illustrates the installation of a channel cover device for a container discharge port according to an embodiment of the present invention. As shown, the upper inner sides of the cover plate 001 are provided with spring clips 103 at both ends, and a limiting part 104, which is U-shaped, is provided in the middle of the upper inner side of the cover plate 001. The upper outer sides of the recessed platform 201 are provided with two square holes 203, and the middle of the upper outer side of the recessed platform 201 is provided with a slot 204, the bottom of which has a protruding structure. During installation, the operator engages the spring clips 103 of the cover plate 001 with the square holes 203 at both ends of the upper outer side of the recessed platform 201, and simultaneously engages the limiting part 104 of the cover plate 001 with the slot 204 in the middle of the upper outer side of the recessed platform 201, thus limiting the cover plate 001. At this time, the cover plate 001 can be flipped open or closed twice through the first rotating shaft 101 and the second rotating shaft 102 to open or close the discharge port channel.

[0052] In addition, when the cover plate 001 is in the closed state, there is a gap between the middle of the lower end of the cover plate 001 and the bottom surface of the lock hole 208, so that the operator can insert his / her fingers into the lock hole 208 to lift the cover plate 001.

[0053] When opening the cover of the discharge port channel, the operator inserts their fingers into the locking hole 208 of the base, presses against the lower part of the cover 001, and lifts it upwards. The parts of the cover 001 located on both sides of the first rotating shaft 101 flip relative to each other, and the parts of the cover 001 located on both sides of the second rotating shaft 102 flip relative to each other. After lifting to a certain height, the two protrusions 106 at both ends of the lower part of the cover 001 are fastened and locked into the groove 206 of the base. At this time, the parts of the cover 001 located on both sides of the first rotating shaft are almost flat, and the parts of the cover 001 located on both sides of the second rotating shaft form a certain angle. Under the effect of its own weight and the limiting cooperation of the groove and the protrusion, the cover 001 remains in the open position of the channel.

[0054] When closing the cover plate of the discharge port channel, the operator gently lifts the lower middle position of the cover plate 001 with their fingers, causing the protrusions 106 at both ends of the lower part of the cover plate 001 to disengage from the grooves 206 of the base. At this time, the first rotating shaft 101 and the second rotating shaft 102 of the cover plate 001 rotate back under their own gravity. When the cover plate 001 almost covers the discharge port channel, gently press the lower part of the cover plate 001. At this time, the buckle 107 of the cover plate 001 engages with the rib 207 of the base, so that the cover plate 001 can be kept in the closed position. At this time, cable ties can be further used as needed to achieve dustproof and anti-theft opening functions.

[0055] In one embodiment of this utility model, the cover plate 001 is an independent flat plate structure, which is close to rectangular. The cover plate 001 is mainly made of copolymer polypropylene (i.e. PP) plastic, which has good toughness and is resistant to bending, so it is suitable as a material for flip cover.

[0056] In addition, such as Figure 1 As shown, this utility model also discloses a container, including the cover device for the container discharge port channel described above.

[0057] It should be understood that the structure described above is only one or more embodiments of this utility model. In other embodiments of this utility model, the structure can be appropriately adjusted according to actual needs. For example, the cover plate can be fixed to the base by other connection methods, such as threaded connection, welding, bonding, etc.

[0058] Although various embodiments of the present invention have been described above, it should be understood that they are presented by way of example only and not as limitations. It will be apparent to those skilled in the art that various combinations, modifications, and alterations can be made without departing from the spirit and scope of the present invention.
