[0019] The utility model is described in detail below in combination with the drawings and examples.

[0020] Example: A pressure-resistant plastic bucket, such as Figure 1 As shown, the device includes a plastic bucket body 1, which is injection molded from a modified polyethylene material with added styrene-butadiene rubber. The rubber segments in the styrene-butadiene rubber can cross-link with the polymer segments in the polyethylene to form a three-dimensional network structure, which makes the styrene-butadiene rubber act like a spring in the polyethylene matrix. This allows the plastic bucket body 1, made of modified polyethylene material, to absorb and disperse the energy of external impacts or vibrations, thereby improving the strength and toughness of the plastic bucket body 1.

[0021] like Figures 1-3 As shown, during injection molding, the bottom of the plastic bucket body 1 is integrally formed with an arc-shaped recess 2 and a circular through groove 3. A cylindrical anti-pressure component 4 is engaged in the through groove 3. The diameter of the anti-pressure component 4 is the same as the diameter of the through groove 3, so that the peripheral wall of the anti-pressure component 4 abuts tightly against the inner wall of the through groove 3. The diameter of the opening of the recess 2 is the same as the diameter of the through groove 3. The recess 2 and the through groove 3 are symmetrically arranged vertically along the height direction of the plastic bucket body 1. The recess 2 and the through groove 3 are interconnected, so that a cavity 5 is formed between the recess 2 and the anti-pressure component 4. The cavity 5 can play a buffering role in the event of a collision. At the same time, the cavity 5 can disperse the stress formed on the plastic bucket body 1, avoid stress concentration, and help improve the impact resistance and pressure resistance of the plastic bucket body 1.

[0022] like Figures 1-3 As shown, the arc-shaped recess 2 prevents the pressure-resistant component 4 from entering the space 1. The thickness of the pressure-resistant component 4 is greater than the depth of the through groove 3, so that the end of the pressure-resistant component 4 away from the recess 2 passes through the through groove 3. When the plastic bucket body 1 is being transported, the pressure-resistant component 4 will contact the ground first. The pressure-resistant component 4 is made of polyurethane, which has good elasticity and wear resistance. The pressure-resistant component 4 and the cavity 5 can provide cushioning when the plastic bucket body 1 collides with the ground, reducing the pressure on the plastic bucket body 1 during the collision, and further improving the pressure resistance and impact resistance of the plastic bucket body 1.

[0023] like Figure 1 , Figure 2 and Figure 4As shown, the side wall of the plastic bucket body 1 is integrally formed with four annular grooves 6 during injection molding, four grooves 6 are located on the front, back, left side and right side of the plastic bucket body 1 respectively, an annular protrusion 7 is clamped in the groove 6, the cross-sectional shape of the protrusion 7 is the same as that of the groove 6, the width of the protrusion 7 is the same as that of the groove 6, so that the side wall of the protrusion 7 is in close contact with the inner wall of the groove 6, the end of the protrusion 7 away from the groove 6 is integrally formed with an annular compression-resistant piece two 9, the width of the compression-resistant piece two 9 is greater than that of the protrusion 7, when the protrusion 7 is clamped in the groove 6, the side of the compression-resistant piece two 9 close to the groove 6 is in contact with the side wall of the plastic bucket body 1, the thickness of the protrusion 7 is less than the depth of the groove 6, so that a cavity two 8 is formed between the protrusion 7 and the groove 6, the compression-resistant piece two 9 is made of polyurethane material, through the cavity two 8 and the compression-resistant piece two 9, the side wall of the plastic bucket body 1 can provide cushioning when colliding with other objects, and at the same time, the stress on the side wall of the plastic bucket body 1 during the collision is dispersed, avoiding damage due to stress concentration during the collision.

[0024] As shown in the drawings, Figures 1-3 As shown, the top surface of the plastic bucket body 1 is integrally formed with a recess two 10 during injection molding, the plastic bucket body 1 is integrally formed with a liquid outlet 11 and a handle 12 at the concave surface of the recess two 10 during injection molding, the liquid outlet 11 is detachably connected with an end cover 13, the end cover 13 is made of modified polyethylene material, the top surface of the end cover 13 is glued with a compression-resistant piece three 14 made of polyurethane material, the compression-resistant piece three 14 is cylindrical, the handle 12 is glued with a compression-resistant piece four 15 made of polyurethane material, the compression-resistant piece four 15 is rectangular, the top surface of the plastic bucket body 1, the top surface of the end cover 13 and the top surface of the handle 12 are located on the same horizontal plane, so that the height of the compression-resistant piece three 14 and the height of the compression-resistant piece four 15 are higher than the height of the top surface of the plastic bucket body 1, through the compression-resistant piece three 14 and the compression-resistant piece four 15, the top of the plastic bucket body 1 can provide cushioning when colliding with other objects, and at the same time, the stress on the top of the plastic bucket body 1 during the collision is dispersed.
