Detailed ways

The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

As shown in Figure 1, it is a schematic structural diagram of a traditional paint bucket, which includes a cover body 1 and a bucket body 2. The cover body 1 is provided with a groove 6 for burying a flexible pipe 4 communicating with the barrel cavity. The outlet passes through the threaded cover 3. In the unopened state, the cover 3 and the flexible tube 4 are embedded in the groove 6. When in use, the flexible tube 4 is pulled out of the groove 6, and then the cover 3 is opened to dump the inner coating. The pouring device is limited by the size of the flexible pipe 4, so the pouring spout 7 cannot be designed to be large, and the size of the pouring spout 7 accounts for only 10%-15% of the size of the barrel opening, which leads to a low flow rate when pouring paint. The pouring is faster. The worker can remove the easy-tear part 5 at the connection between the cover body 1 and the barrel body 2, and then separate the cover body 1 and the barrel body 2 by a crowbar, but this process is also inconvenient.

Aiming at the design defects of traditional paint buckets, as shown in Figures 2-6, the present invention designs a convenient and quick dumping device for a rotary button-type paint bucket, which can improve the pouring efficiency when used in traditional paint buckets. The body 1 has been improved, specifically: as shown in FIG. 3 , it includes a pouring spout 7 opened in the middle of the cover body 1 and a cover 3 that is set on the pouring spout 7, and the orifice of the pouring spout 7 is a pipe stand 12 Structure, the upper and lower sides extend out of the surface of the cover body 1 for a distance, the lower end surface of the tube table 12 has an inwardly extending flange 13, and the lower surface of the flange 13 is covered with an adhesive with a sealing film 6 to seal the pouring spout 7. The membrane 6 has a certain toughness, and can withstand the pressure of the paint in the barrel as the liquid in the barrel shakes when handling and transporting the paint barrel to prevent leakage. The cover 3 is detachably connected to the pipe stand 12 of the pouring spout 7 through the structure of a rotary buckle. Specifically, as shown in FIG. 4 , the inner side of the pipe stand 12 is circumferentially spaced with a plurality of snap-fit pieces 1 4 . Between one and four is a through slot one 8. As shown in FIG. 5 , the outer side of the cover 3 is provided with a plurality of clips two 5 corresponding to the interval width of the clip one 4 in the circumferential direction. There is a through-slot 2 9 in between, and the clip-connecting piece 1 4 and the clip-connecting piece 2 5 can just form a complete circle when they are staggered; Corresponding to the position of the second through-slot 9 and the clamping piece 2 5 corresponding to the through-slot 18, insert the clamping piece 25 of the cover 3 through the through-slot 1 8 of the clamping piece 1 4 until the lower end of the cover 3 is in contact with the protrusion. The edge 13 is abutted, and then the cover 3 is rotated circumferentially so that the clip two 5 is placed on the lower part of the clip one 4 and the projections of the two overlap. At this time, the cover 3 is restricted by the clip one 4 and the flange 13. , the axial movement cannot be formed, and the assembly of the cover 3 and the cover body 1 is completed, as shown in FIG. 6 . The above-mentioned rotary buckle can realize the function of quick disassembly and assembly, and the rotary buckle can fully fix the axial direction of the cover 3. Even if the sealing membrane 6 is deformed due to excessive pressure, the connection structure of the cover 3 and the tube table 12 can be sealed. Membrane 6 forms protection and further resistance to the pressure in the barrel.

The barrel body 2, the cover body 1 and the cover 3 in the present invention are all processed by the mold injection process in the prior art, and the material is also the same as that of the existing paint barrel, and the composite resin material is used. The barrel body 2 and the cover body 1 The connection method adopts the existing gland connection to ensure the connection strength of the barrel body 2 and the cover body 1. The connection between the two can also be designed with easy tearing parts, depending on the situation. The processing method of the sealing film 6 adopts the sealing film process in the prior art, and the material is selected from conventional materials such as PP and PET, and the specific selection can refer to the composition of the solution in the barrel.

Among them, the above-mentioned sealing film 6 can also be attached to the barrel mouth surface of the barrel body 2 to seal the barrel body 2. In such a film coating method, the barrel mouth wall thickness of the barrel body 2 should reach 0.2-1cm to increase the sealing effect. The connection area between the film 6 and the end face of the barrel mouth ensures the strength of the sticking.

The working principle of the present invention is as follows:

Based on the design that the cover 3 and the pouring spout 7 are quick-release connections, the ratio of the size of the pouring spout 7 to the size of the bucket opening can be increased to 60%-90%, which is impossible for the pouring spout 7 on the traditional bucket lid. Therefore, the flow rate of the paint in the pouring port 7 and the working efficiency of pouring the paint can be improved. When in use, the cover 3 can be easily disassembled by manual rotation, or the surface of the cover 3 can be rotated and disassembled by using a suction cup tool, and then the sealing film 6 can be scratched with a knife to carry out the work of pouring the paint. The whole operation The process is simple and fast. The invention can not only be used for paint packaging barrels, but also can be used for packaging barrels in industries such as lubricating oil, agricultural fertilizer, veterinary medicine, and antifreeze.

In order to reduce the production cost, the middle of the cover 3 is recessed downward to form a cylindrical structure.

As shown in FIG. 6 , the distance L1 from the lower side of the clip 1 4 to the upper side of the flange 13 < the distance L2 from the upper side of the clip 2 5 to the lower end of the cover 3 (L1>L2 in the figure is due to extrusion deformation after effect). This design is for the purpose of deforming the clip-1 4 or the flange 13 , thereby improving the clamping strength of the two to the cover 3 and preventing the cover 3 from rotating. The distance difference is 1-2mm.

As shown in FIG. 7 , in order to prevent the cover 3 from rotating, a limiting mechanism may be separately provided at the connection between the cover 3 and the cover body 1 . Specifically, the limit mechanism includes a limit groove 11 formed on the upper surface of the flange 13 and a limit bump 10 disposed on the lower end of the cover 3 and inserted into the limit groove 11 . The flange 13 is in contact with the lower end of the cover 3 , and a limit mechanism is preferably provided there, which can facilitate positioning.

The shape of the limiting bump 10 and the limiting slot 11 is hemispherical, and can also be other shapes, such as a cube, and the limiting slot 11 can be in the shape of a through hole or a blind hole.

The cross-sectional shape of the first clip 4 and the second clip 5 is a triangle, a rectangle or a trapezoid. The clips in FIG. 3 are rectangular, and the clips in FIG. 6 are triangles. The specific shape requirements are determined according to the base material. When the strength of the base material is high, a triangle is used, which can reduce the cost.

The preferred ratio of the diameter of the pouring spout 7 to the diameter of the cover body 1 is 2-4.5:5.

The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited to this. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention. should be included within the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
