Description

Technical Field

[0001] The invention relates to a logistics container, and more particularly to a fixing clamp for a discharge port of an intermediate bulk container. Background Art

[0002] Nowadays, it is very common to use large containers to transport bulk liquids. These containers are made of metal, wood, and plastic. They usually include a bottom plate and four side plates. Due to sealing issues, a liner bag is often placed inside the container, and the liquid is then placed in the liner bag. The container is then covered with a lid to protect the liner bag from being easily damaged.

[0003] When the liquid in the container needs to be discharged, the conventional method is to open a hole on the side of the lower part of the container, and the lower part of the liner bag has a discharge port. The flange of the discharge port is welded to the liner bag, and the discharge port is aligned with the hole on the container when the liner bag is placed in the container. Most of these discharge ports do not have valves themselves, and the thin membrane between the discharge channel of the discharge port and the inside of the liner bag is retained. The membrane will only be punctured when the discharge port is connected to a pipe with a valve. Some discharge ports have valves, and their discharge channels are directly connected to the inside of the liner bag. Liquid can be discharged by directly connecting to the pipe. Or it can be a switchable valve. When discharging, the external joint pipe is connected to the valve, and the valve is opened to discharge the liquid.

[0004] These discharge ports have a specific shape near the root of the flange, such as a square or hexagonal shape. These specific shapes are used to connect with a fixing clip. When the liner bag is placed in the container, the fixing clip will first be clamped on the discharge port, and then the fixing clip will be snapped into the opening below the container. In this way, the discharge port is fixed on the container, protecting the liner bag from being easily damaged during use. However, after assembling the fixing clip, the discharge port may be tampered with, resulting in liquid leakage. Therefore, the art needs a discharge port fixing clip that is simple in structure, easy to operate, and can reliably prevent tampering. Summary of the invention

In the following description, for the purpose of illustrating various disclosed embodiments, certain specific details are set forth to provide a thorough understanding of the various disclosed embodiments. However, those skilled in the relevant art will recognize that the embodiments can be practiced without one or more of these specific details.

[0042] Figure 1 2 is a three-dimensional diagram of a discharge port fixing clip 2 according to an embodiment of the present invention. The discharge port fixing clip 2 comprises a fixing clip body 21 , an elastic connecting buckle 25 , a surrounding portion 23 and an anti-tampering cover plate 24 . Figure 2 The 3D diagram shows a discharge port 1. The discharge port 1 is a hexagonal discharge port, and includes a flange 11, a discharge port clamp 12 and a discharge interface 13. Figure 3 A bottom perspective view of the stomal fixing clamp 2 is shown in FIG.

[0043] like Figure 3 As shown, the proximal end of the fixing clamp body 21 is provided with an opening, and a discharge port clamping position 12 (see FIG. Figure 2 ) opening 211. The clamping portion 22 is located on both sides of the fixing clamp body 21 and forms an opening 211 that matches the contour of the discharge channel, specifically the discharge port clamp 12. Figure 2) After assembly, the clamping portion 22 clamps the opposite side of the discharge port clamping position 12 of the discharge port 1. The surrounding portion 23 extends from the fixing clip body 21 along the outer periphery of the opening 211. In the illustrated embodiment, the surrounding portion 23 extends vertically upward from the fixing clip body 21, but it should be understood that the surrounding portion 23 is not necessarily perpendicular to the fixing clip body 21, and can also be inclined relative to the fixing clip body 21, for example, in a shape that gradually shrinks or expands from the bottom end to the top end. Specifically, the bottom end of the surrounding portion 23 is located between the periphery of the opening 211 and the elastic connecting buckle 25, and roughly surrounds the portion of the fixing clip body 21 except the opening. In the illustrated embodiment, the anti-tampering cover plate 24 covers the top end of the surrounding portion 23 and is circumferentially connected to the top end of the surrounding portion 23. In the illustrated embodiment, the size and shape of the anti-tampering cover plate 24 match the shape of the top opening of the surrounding portion 23, but it should be understood that the size of the anti-tampering cover plate 24 can exceed the top opening of the surrounding portion 23, or it can be smaller than the size of the surrounding portion 23 and only connected to the top opening of the surrounding portion 23 at a portion of its periphery. It should be understood that the tamper-proof cover plate 24 is not necessarily in the shape of a flat plate, and may be, for example, in the shape of a dome or other curved surface. It is also conceivable that the surrounding portion 23 and the tamper-proof cover plate 24 may together form a dome shape, connected by a weakening line.

[0044] A circumferential tearable portion is provided between the anti-tamper cover plate 24 and the fixing clamp body 21. Specifically, a circumferential weakening line is provided at least at one of the anti-tamper cover plate, the connection between the anti-tamper cover plate and the surrounding portion, the surrounding portion, and the connection between the surrounding portion and the fixing clamp body, and the connection strength at the weakening line is less than the connection strength of the remaining parts of the discharge port fixing clamp. Therefore, when an upward force is applied to the anti-tamper cover plate 24, a break occurs along the weakening line. In the illustrated embodiment, the weakening line is provided at the circumferential connection between the anti-tamper cover plate 24 and the top edge of the surrounding portion 23, and specifically is composed of a plurality of breakable connection points 29 circumferentially spaced from each other, such as Figure 3 As shown. However, it should be understood that the weakening line can also be set on the anti-tamper cover plate along the circumferential direction, so that when an upward force is applied to the middle part of the anti-tamper cover plate 24, the middle part of the anti-tamper cover plate 24 breaks from the circumferential edge of the anti-tamper cover plate 24 along the weakening line. The weakening line can also be set on the surrounding part 23, so that when an upward force is applied to the middle part of the anti-tamper cover plate 24, the anti-tamper cover plate 24 and a part of the surrounding part 23 (the upper part in the figure) break from another part of the surrounding part 23 (the lower part in the figure) along the weakening line. The weakening line can also be set at the connection between the surrounding part 23 and the fixing clip body 21, so that when an upward force is applied to the middle part of the anti-tamper cover plate 24, the anti-tamper cover plate 24 breaks from the fixing clip body 21 together with the surrounding part 23. It should be understood that the weakening line can be set continuously or discontinuously along the circumferential direction. The weakening line can be arranged in a straight line or in a curved or serrated shape.

[0045] Due to the provision of the tearable portion, when the discharge port 1 is opened for the first time, the anti-tampering cover plate 24 needs to be torn off from the fixing clamp body 21 to expose the discharge interface 13. Therefore, the operator can identify whether the discharge port 1 has been opened by observing whether the anti-tampering cover plate 24 is intact. In order to facilitate the tearing off of the anti-tampering cover plate 24, a tear hole can be provided on the anti-tampering cover plate 24 and / or the surrounding portion 23, or a pulling portion (not shown) protruding from the anti-tampering cover plate 24 can be provided. The size of the tear hole allows a person's finger to pass through. The pulling portion can be a pull ring, a pull handle or other structure that is easy to grasp protruding from the anti-tampering cover plate 24.

[0046] In addition, in order to more conveniently identify whether the discharge port 1 has been opened, the color of the anti-tamper cover plate 24 can be set to be different from that of the remaining parts.

[0047] The discharge port fixing clip 2 is generally made of plastic material, and the structure of the fixing clip is preferably made so that multiple fixing clips can be stacked together.

[0048] The elastic connection buckle 25 extends upward from both sides of the fixing clamp body 21 and is used to cooperate with the discharge channel at the bottom of the intermediate bulk container so that the discharge port 1 is fixed relative to the container. The discharge channel of the intermediate bulk container is generally square, so the shape of the fixing clamp body is also square to match the discharge channel. The elastic connection buckle 25 is a plastic elastic component. When installed, it deforms due to elasticity, and after contacting the corresponding structure on the discharge channel, it deforms and resets to complete the installation.

[0049] In addition, if Figure 3 As shown, the discharge port fixing clamp 2 of the present invention may further include an elastic introduction rib 26 and a non-return portion 27. Preferably, an inwardly facing groove portion is provided at the end of the clamping portion 22 to accommodate the elastic introduction rib 26 and the non-return portion 27. The elastic introduction rib 26 extends obliquely from the end of the clamping portion 22 toward the inside of the opening 211, and the non-return portion 27 extends obliquely outward from the end of the elastic introduction rib 26. A limiting rib 271 is provided at the end of the non-return portion 27, and a limiting step 221 is provided at the edge of the opening 211 of the clamping portion 22, as shown in FIG. Figure 5 The limiting rib 271 is limited by the limiting step 221 and cannot deviate inwardly.

[0050] The fixing clip 2 of the present invention can be pushed in horizontally to complete the assembly with the discharge port. The elastic introduction rib 26 is an elastic plastic part. During the pushing process, the elastic introduction rib 26 is squeezed and deformed and rotated outward. After the assembly is completed, the clamping portion 22 can tightly clamp the hexagonal clamping position 11, thereby fixing the discharge port 1 so that it cannot move up, down, left, or right relative to the fixing clip 2.

[0051] The tail end of the elastic introduction rib 26 is connected to the non-return portion 27. After the fixing clip 2 and the discharge port 1 are assembled, the non-return portion 27 can press against the discharge port to prevent the fixing clip 2 from being separated from the discharge port.

[0052] Figure 5-8 1 is a schematic diagram of the assembly process of the fixing clip 2 and the hexagonal discharge port 1 according to the first embodiment of the present invention. During assembly, the fixing clip 2 is pushed to move parallel to the discharge port 1. When the introduction surface of the elastic introduction rib 26 on the fixing clip 2 contacts the discharge port clamping position 11 (see FIG. Figure 6 ), continue to push the fixing clip 2, the elastic introduction rib 26 will be squeezed by the discharge port clamp 11 to deform and rotate outward (see Figure 7 ), when the fixing clamp 2 and the discharge port 1 are assembled in place (see Figure 8 ), the elastic introduction rib 26 of the fixing clip 2 is no longer squeezed and recovers. At this time, the clamping portion 22 of the fixing clip clamps the discharge port clamping position 11, and the non-return surface of the non-return portion 27 connected to the end of the elastic introduction rib 26 cooperates with the side of the discharge port clamping position 11 to prevent the fixing clip and the discharge port from loosening. When the fixing clip and the discharge port are assembled, the fixing clip 2 and the discharge port 1 assembled as one are fixed to the discharge channel at the bottom of the intermediate bulk container through the elastic connecting buckle 25, so that the discharge port 1 will not shake relative to the discharge channel, which is conducive to reducing damage to the discharge port.

[0053] It is worth noting that, as shown in the figure, the fixing clamp of the present invention is provided with a limiting rib 271 at the end of the non-return portion 27 and a limiting step 221 at the top of the clamping portion 22. During installation and transportation, if the fixing clamp is subjected to a force away from the discharge port, the interaction force generated between the side edge of the discharge port and the non-return portion 27 may cause the elastic introduction rib 26 to deviate inward and be easily damaged or cause the fixing clamp to loosen from the discharge port. However, if the elastic introduction rib 26 is relatively elastic, the limiting rib 271 and the limiting step 221 may not be provided.

[0054] Fig. 9 The discharge port 1' in the embodiment is a quadrilateral. The fixing clip of the first embodiment of the present invention can also be used to fix Fig. 9 The quadrilateral discharge port 1' comprises a flange edge 11', a discharge port clamping position 12' and a discharge interface 13'. Figure 10-13 Schematic diagram of the assembly process of the fixing clip and the quadrilateral discharge port according to the first embodiment of the present invention. Fig.14It is a schematic diagram of the three-dimensional structure when the fixing clamp and the quadrilateral discharge port are assembled according to the first embodiment of the present invention. The assembly process is almost the same as the assembly process of the hexagonal discharge port and the fixing clamp. The angle of the quadrilateral clamping position is formed as a chamfer with a certain arc so as to better cooperate with the non-return portion 27. When the fixing clamp needs to be removed from the discharge port, the elastic introduction rib can be manually squeezed outward to deform it, so that the non-return portion or the non-return hanging platform is disengaged from the side structure of the clamping position, and then the fixing clamp can be pulled to separate from the discharge port.

[0055] The structure of the discharge port fixing clip 2 in the above embodiment is a push-fitting type, but it should be understood that the specific fitting and assembly method of the discharge port fixing clip 2 does not affect the scope of the present invention, as long as the discharge port fixing clip 2 is provided with a tearable anti-tampering cover 24. The discharge port fixing clip 2 may also have other fitting structures, such as that described in Chinese patent publication CN109353714A, in which the clamping portion and the opening portion are hinged to each other, and after the clamping portion is clamped to the discharge port, the two are closed to be fixed relative to the discharge port. The above patent publication is cited here for reference.

[0056] The discharge port fixing clamp according to the present invention has a simple structure, is easy to operate and can reliably identify whether the discharge port has been opened.
