[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] The present utility model provides a high-sealing and moisture-proof polyethylene blow-molded bucket as shown in Figures 1-3 which includes a bucket body 1. A bucket mouth 2 is fixedly arranged at the top end of the bucket body 1. A sealing seat 3 is fixedly arranged at the top end of the bucket mouth 2. A connecting sleeve 4 with an annular structure is fixedly arranged in the middle of the top end of the sealing seat 3. A feeding ring 5 is fixedly arranged at the top end of the connecting sleeve 4. The setting of the feeding ring 5 facilitates the pouring of the materials inside the bucket body 1 to avoid the materials entering between the connecting sleeve 4 and the sealing sleeve 7.
[0022] Specifically, a bucket lid 6 is sleeved outside the connecting sleeve 4. A sealing sleeve 7 is fixedly arranged at the top end of the outer side wall of the sealing seat 3. An external thread 8 is provided on the outer side wall of the sealing sleeve 7. An internal thread 9 is provided on the inner side wall of the bucket lid 6, and the internal thread 9 is adapted to the external thread 8.
[0023] More specifically, an extension ring 10 is fixedly arranged at the top end of the inner side wall of the bucket lid 6. An annular sleeve 11 is fixedly arranged at the bottom end of the inner side wall of the extension ring 10, and the annular sleeve 11 is arranged between the sealing sleeve 7 and the connecting sleeve 4. Inclined surfaces 12 are provided at the top end of the inner side wall of the sealing sleeve 7 and the bottom end of the outer side wall of the annular sleeve 11. The setting of the inclined surfaces 12 facilitates the insertion of the annular sleeve 11 between the sealing sleeve 7 and the connecting sleeve 4.
[0024] Moreover, a pressing block 13 is fixedly arranged at the bottom end of the inner side wall of the sealing sleeve 7, and the pressing block 13 is attached to the outer side wall of the annular sleeve 11. A plurality of strip-shaped grooves 14 are penetratingly arranged on the outer side wall of the sealing sleeve 7, and the plurality of strip-shaped grooves 14 are arranged in a surrounding manner. During the downward movement of the bucket lid 6, the annular sleeve 11 squeezes the pressing block 13, so that the pressing block 13 drives the sealing sleeve 7 to move, thereby enabling the sealing sleeve 7 to expand outwards along the strip-shaped grooves 14, so that the sealing sleeve 7 and the bucket lid 6 are tightly abutted against each other to ensure the stability after the bucket lid 6 is tightened;
[0025] In addition, a sealing plug 15 is fixedly arranged at the top end of the inner side wall of the bucket lid 6, and a fixing ring 16 corresponding to the sealing plug 15 is fixedly arranged at the bottom end of the inner side wall of the connecting sleeve 4. An annular groove 17 is formed on the upper surface of the fixing ring 16, and the groove 17 corresponds to the bottom end of the sealing plug 15. A plurality of strengthening blocks 18 are fixedly arranged on the lower surface of the fixing ring 16, and the plurality of strengthening blocks 18 are arranged in a surrounding manner. The strengthening blocks 18 can increase the structural strength of the fixing ring 16.
[0026] The working principle of the present utility model:
[0027] When the device is in use, the bucket body 1 and the bucket lid 6 can be respectively produced by blow molding. During use, the product can be injected into the bucket body 1 through the bucket mouth 2 at the top end of the bucket body 1. When sealing the bucket body 1, the bucket lid 6 is placed above the sealing seat 3, and the annular sleeve 11 inside the bucket lid 6 is inserted between the sealing sleeve 7 and the connecting sleeve 4 through the guidance of the inclined surface 12. Then, the bucket lid 6 is rotated, so that the bucket lid 6 moves downward under the action of the external thread 8 and the internal thread 9. At this time, the annular sleeve 11 and the connecting sleeve 4 are tightly attached, and the sealing plug 15 inside the bucket lid 6 is pressed tightly in the groove 17 above the fixing ring 16 to achieve the sealing of the bucket body 1. During the downward movement of the bucket lid 6, the annular sleeve 11 squeezes the pressing block 13, so that the pressing block 13 drives the sealing sleeve 7 to move, thereby enabling the sealing sleeve 7 to expand outwards along the strip-shaped grooves 14, so that the sealing sleeve 7 and the bucket lid 6 are tightly abutted against each other to ensure the stability after the bucket lid 6 is tightened, thereby ensuring the sealing performance of the bucket body 1.
[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
