Description

Technical Field

[0001] The utility model relates to the technical field of packaging barrel sealing, in particular to a sealing device for a chemical product packaging barrel. Background Art

[0002] During the transportation of chemicals, it is necessary to store the chemicals in packaging barrels in advance. Storing the chemicals in the packaging barrels will facilitate their transportation later. After the chemicals are stored in the packaging barrels, the packaging barrels need to be sealed. When sealing, the packaging barrels and the cover body must be tightly connected. The tight connection can maintain the quality of the chemicals and prevent quality changes. When sealing the packaging barrels, corresponding packaging barrel sealing devices need to be used.

[0003] The sealing cover of the metal packaging barrel usually achieves the sealing effect through a screw seal, but this sealing method has some defects: once the screw of the sealing cover is loose, it may be difficult to reseal, affecting the sealing effect. In addition, the screw seal requires a special screw cover tool. If there is no tool, it cannot be sealed. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Utility Model Content

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] See also Figure 1-4A sealing device for a chemical product packaging barrel comprises a barrel body 1 and a cover body 2, wherein a fixing ring 3 is fixedly arranged on the inner wall of the barrel body 1, a hollow disk 4 is fixedly arranged in the cover body 2, a plurality of through holes are arranged in a side wall array of the hollow disk 4, a limiting rod 5 is slidably arranged in the through hole, and a sealing ring is arranged in the through hole, a driving assembly is also arranged in the cover body 2, and the driving assembly is used to provide power for the synchronous extension and retraction of a plurality of limiting rods 5. By arranging the fixing ring 3, the hollow disk 4, the limiting rod 5 and the driving assembly, when the driving assembly drives the plurality of limiting rods 5 to extend outward synchronously, the plurality of limiting rods 5 are inserted under the fixing ring 3, so that the cover body 2 can be fixed and the barrel body 1 can be sealed. Compared with the prior art in which sealing is achieved by a spiral method, no special screw cover tool is required, and the sealing and opening are convenient and quick.

[0020] Among them, the driving assembly includes a turntable 6, an installation shaft 7, a slider 8, a connecting rod 9 and a rotating unit. The turntable 6 is rotatably set in the hollow disk 4 through the installation shaft 7 and driven by the rotating unit. The hollow disk 4 is also arranged in an array with the same number of sliders 8 as the limit rods 5 around the turntable 6. The sliders 8 are movably set through slide rails 10, the limit rod 5 is fixedly installed on one side of the slider 8, and the other side of the slider 8 is connected to the turntable 6 through the connecting rod 9, wherein one end of the connecting rod 9 is rotatably set on the side of the slider 8, and the other end is rotatably installed on the end face of the turntable 6 through a positioning pin.

[0021] Preferably, the rotating unit includes a stud 11 threadedly mounted on the cover body 2, a handwheel 12 is mounted on one end of the stud 11, and an insertion rod 13 is fixedly mounted on the other end. A slot 14 for plugging and cooperating with the insertion rod 13 is provided on the mounting shaft 7. The rotating unit utilizes a spiral push method, which can not only automatically realize the rotation and fixation of the turntable 6, but also has the advantages of simple structure and low cost.

[0022] Specifically, when it is necessary to seal the barrel body 1, it is only necessary to cover the barrel body 1 with the cover body 2, and then rotate the handwheel 12 on the cover body 2. When the handwheel 12 drives the stud 11 to rotate into the cover body 2, the turntable 6 can be driven to rotate. Under the transmission of multiple connecting rods 9 and the guide limit of multiple slide rails 10, multiple sliders 8 move synchronously in the axial direction of the original turntable 6, thereby driving multiple limit rods 5 to synchronously extend out of the hollow disk 4 and extend to the bottom of the fixing ring 3, so as to fix the cover body 2 and seal the barrel body 1. Conversely, when it is necessary to open the barrel body 1, it is only necessary to reversely rotate the handwheel 12 to release the fixation of the cover body 2.

[0023] In addition, a limiting ring 15 is fixedly installed inside the cover body 2 on the outside of the hollow disk 4, and a rubber sealing gasket 16 is arranged between the cover body 2 and the limiting ring 15. The arrangement of the limiting ring 15 and the rubber sealing gasket 16 further improves the sealing effect of the cover body 2 on the barrel body 1.

[0024] Furthermore, the end surface of the limiting rod 5 close to the top surface of the cover body 2 is wedge-shaped. Through such an arrangement, when multiple limiting rods 5 move synchronously toward the fixing ring 3, the wedge-shaped structure of the end surface of the limiting rod 5 can make the cover body 2 move downward a certain distance, thereby achieving the squeezing of the rubber sealing pad 16, further improving the sealing effect of the cover body 2 on the barrel body 1.

[0025] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
