DETAILED DESCRIPTION
[0018] The following is combined with Figure 1-3 This application is described in further detail.
[0019] The present application embodiment discloses a plastic bucket leak-proof structure. Figure 1, including a barrel body 1, the outer wall of the top of the barrel body 1 is rotatably connected with a handle 4, the side wall of the top of the barrel body 1 is symmetrically fixed with a connecting ear 6, the inside of the connecting ear 6 is fixedly connected with a rotating shaft 7, and the end of the rotating shaft 7 away from the connecting ear 6 is rotatably connected to the handle 4. The setting of the handle 4 facilitates the transportation of the barrel body 1 and improves portability. A thickened barrel bottom 2 is installed at the bottom of the barrel body 1 in an integrated structure. It is made of high-strength plastic material, has excellent impact resistance and corrosion resistance, can resist the adverse effects of the external environment, and prolongs its service life.
[0020] like Figure 2 As shown, a leakproof trap 5 is installed on the outer wall of the top of the barrel body 1, and a fitting sleeve 8 is fixed to the bottom end of the leakproof trap 5 in an integrated structure. The fitting sleeve 8 is threadedly connected to the outer wall of the barrel body 1, and a drainage head 9 for discharging internal accumulated water is installed on the side wall of the fitting sleeve 8, which plays a good sealing role. A leakproof cover 3 is provided inside the leakproof trap 5, and an annular cavity 10 is opened in the leakproof trap 5, and the annular cavity 10 is set as a space for accommodating the movement of the leakproof cover 3;
[0021] The top of the barrel body 1 is an integral structure with a barrel mouth 11, the outer wall of the barrel mouth 11 is provided with a thread 12, and the bottom end of the leak-proof cover 3 is an integral structure with a connecting cover 13 fixed thereto, which is adapted to the thread 12 for convenient operation to connect the leak-proof cover 3 to the barrel body 1.
[0022] Combination Figure 3 As shown, a guide tube 16 is fixedly connected to one side of the top of the leak-proof cover 3. The edge of the guide tube 16 is arranged in an arc shape, which can guide the internal water flow to avoid water splashing. A bottle mouth 14 is arranged inside the guide tube 16, and the bottle mouth 14 extends into the connecting cover 13. The outside of the bottle mouth 14 is sealed and connected with a sealing cover 15. When the sealing cover 15 is opened, the internal liquid can also be discharged through the bottle mouth 14 to enhance applicability.
[0023] The implementation principle of the anti-leakage structure of a plastic bucket in the embodiment of the present application is:
[0024] When in use, the liquid is stored through the barrel body 1, and then the leak-proof cover 3 is placed in the annular cavity 10, and the connecting cover 13 is rotated to fit and connect with the thread 12, so as to complete the connection between the leak-proof cover 3 and the barrel mouth 11, and the leak-proof trap 5 is covered on the outer wall of the connection between the leak-proof cover 3 and the barrel body 1, which plays a good sealing and leak-proof role, forming a multiple sealing barrier to effectively prevent leakage. If water overflows, it will overflow along the barrel wall into the fitting sleeve 8, and the internal accumulated water can be discharged through the drainage head 9 by opening the sealing cover. The overall strength of the barrel body 1 is enhanced by the setting of the thickened barrel bottom 2, and it has excellent impact resistance and corrosion resistance. The barrel body 1 can be lifted for transportation by the handle 4, and if a small amount of liquid in the barrel body 1 needs to be taken, the barrel body 1 can also be tilted by opening the sealing cover 15. At this time, the liquid can be discharged to the outside through the bottle mouth 14 along the guide tube 16. The overall design is simple and clear, easy to process and assemble, and the applicability is greatly enhanced.
