Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic buckets, especially to an impact-resistant and wear-resistant plastic bucket. BACKGROUND

[0002] Currently, plastic buckets are widely used in chemical industry, food industry, logistics and other fields due to their advantages of light weight, corrosion resistance and low cost. However, the traditional plastic buckets have the following shortcomings in impact resistance and wear resistance:

[0003] 1. Impact resistance defect: ordinary plastic buckets are mostly made of single material (such as HDPE) by injection molding, which has high structural rigidity but insufficient toughness, and is prone to cracking or even breaking under external impact, especially in frequent handling or stacking scenarios, the barrel body and bottom are prone to failure due to stress concentration.

[0004] 2. Insufficient wear resistance: the barrel bottom is prone to wear and tear due to long-term friction with the ground or transportation tools, resulting in leakage or reduced structural strength.

[0005] Therefore, it is necessary to provide a new impact-resistant and wear-resistant plastic bucket to solve the above technical problems. SUMMARY

[0006] To solve the above technical problems, the utility model provides an impact-resistant and wear-resistant plastic bucket.

[0007] The impact-resistant and wear-resistant plastic bucket provided by the utility model comprises a barrel body, a barrel cover is installed on the top of the barrel body, and a partial barrel body structure composed of an elastic expansion sleeve is arranged between the barrel body and the barrel cover.

[0008] A plurality of reinforcing columns are arranged between the barrel body and the barrel cover, which are distributed in a ring shape and used for protecting the elastic expansion sleeve.

[0009] Preferably, one end of the elastic expansion sleeve is fixedly embedded in the barrel body, and the other end of the elastic expansion sleeve is fixedly connected with the cover surface of the barrel cover.

[0010] Preferably, a hollow annular cavity is arranged in the barrel body in a ring shape, and the hollow annular cavity stores inert gas.

[0011] Preferably, an annular air bag is fixedly sleeved on the outer barrel wall of the barrel body, and the inner bag wall of the annular air bag close to the bottom is in communication with the hollow annular cavity.

[0012] Preferably, an elastic rubber sleeve is fixedly embedded in the outer bag wall of the annular air bag.

[0013] Preferably, a ring-shaped piston is slidably connected in the hollow annular cavity.

[0014] Preferably, one end of the reinforcing column is fixedly installed on the lower surface of the barrel cover, and the other end of the reinforcing column is inserted into the hollow annular cavity and fixedly connected with the upper surface of the annular piston.

[0015] Preferably, a plurality of rubber pad rings with decreasing inner diameters are fixedly embedded in the bottom of the barrel body.

[0016] Preferably, a sealing plug for sealing the material opening is inserted into the material opening formed in the barrel cover.

[0017] Compared with the related art, the plastic bucket with impact resistance and wear resistance has the following beneficial effects:

[0018] 1. Since part of the barrel body structure of the plastic bucket is formed by the elastic telescopic sleeve, when the top of the plastic bucket is subjected to downward pressure, the elastic telescopic sleeve can be folded and stored, so that the plastic bucket offsets part of the impact force received by the plastic bucket through elastic deformation, avoids stress concentration on the barrel body, greatly enhances the impact resistance of the plastic bucket, and the reinforcing columns are annularly distributed and connected with the barrel cover and the annular piston, thereby protecting the elastic telescopic sleeve from being overloaded and compressed.

[0019] 2. When the top of the plastic bucket is subjected to downward pressure to drive the elastic telescopic sleeve to shrink, the reinforcing columns compress the inert gas stored in the hollow annular cavity by using the annular piston, thereby further improving the impact resistance of the plastic bucket, and the inert gas in the hollow annular cavity flows into the annular air bag after being extruded, so that the annular air bag is inflated, and the inflated annular air bag can improve the impact resistance of the barrel body of the plastic bucket.

[0024] In order to make the utility model purposes, technical solutions and advantages more clearly, the following will be further described in detail with the help of the accompanying drawings and examples.

[0025] The specific implementation of the utility model will be described in detail in combination with specific examples.

[0026] Please refer to Figures 1 to 3 The utility model discloses an anti-impact wear-resistant plastic bucket, which comprises a bucket body 1, an elastic telescopic sleeve 2 and a reinforcing column 4.

[0027] In the embodiment of the utility model, please refer to Figures 1 to 3 The top of the bucket body 1 is provided with a cylinder cover 11, and a partial bucket body structure formed by the elastic telescopic sleeve 2 is arranged between the bucket body 1 and the cylinder cover 11, one end of the elastic telescopic sleeve 2 is fixedly embedded on the bucket body 1, and the other end of the elastic telescopic sleeve 2 is fixedly connected with the cover surface of the cylinder cover 11.

[0028] It should be noted that: since the partial bucket body structure of the plastic bucket is formed by the elastic telescopic sleeve 2, when the top of the plastic bucket is subjected to downward pressure, the elastic telescopic sleeve 2 can be folded and stored, so that the plastic bucket offsets part of the impact force received by the plastic bucket through elastic deformation, avoids stress concentration on the bucket body 1, and greatly enhances the impact resistance of the plastic bucket.

[0029] In the embodiment of the utility model, please refer to Figures 1 to 3 The reinforcing column 4 is arranged between the bucket body 1 and the cylinder cover 11, and is annularly distributed and used for protecting the elastic telescopic sleeve 2, a hollow annular cavity 1a is formed in the bucket body 1 in an annular distribution mode, inert gas is stored in the hollow annular cavity 1a, an annular air bag 3 is fixedly sleeved on the outer cylinder wall of the bucket body 1, the inner bag wall of the annular air bag 3 close to the bottom is in communication with the hollow annular cavity 1a, an annular piston 5 is slidably connected in the hollow annular cavity 1a, one end of the reinforcing column 4 is fixedly installed on the lower surface of the cylinder cover 11, and the other end of the reinforcing column 4 is inserted into the hollow annular cavity 1a and fixedly connected with the upper surface of the annular piston 5.

[0030] It should be noted that: the reinforcing column 4 is annularly distributed and connected with the cylinder cover 11 and the annular piston 5, which not only protects the elastic telescopic sleeve 2 from being overloaded and compressed, but also disperses the impact force through rigid support, so as to realize the anti-impact effect of "harmony of rigidity and flexibility".

[0031] When the top of the plastic bucket is subjected to downward pressure to drive the elastic telescopic sleeve 2 to shrink, the reinforcing column 4 compresses the inert gas stored in the hollow annular cavity 1a by using the annular piston 5, thereby further improving the impact resistance of the plastic bucket, and the inert gas in the hollow annular cavity 1a flows into the annular air bag 3 after being extruded, so that the annular air bag 3 is inflated, and the inflated annular air bag 3 can improve the impact resistance of the barrel body of the plastic bucket.

[0032] In the embodiment, when the plastic bucket is not impacted, the annular air bag 3 is in a normal inflated state, effectively protecting the barrel body 1.

[0033] Further, the outer bag wall of the annular air bag 3 is fixedly embedded with an elastic rubber sleeve, thereby improving the wear resistance of the annular air bag 3 and reducing the hidden danger of damage of the annular air bag 3.

[0034] Further, the bottom of the barrel body 1 is fixedly embedded with a plurality of rubber pad rings 6 with decreasing inner diameters, and since the rubber pad ring 6 is an elastic structure, the impact on the plastic bucket can also be reduced.

[0035] Further, a seal plug 12 for sealing the material opening is inserted into the material opening formed in the barrel cover 11, and the material opening is convenient for the plastic bucket to store or discharge materials, and the seal plug 12 effectively seals the material opening to prevent material leakage.

[0036] In the scheme, the bottom of the barrel body 1 is also coated with a polyurethane (PU) coating, thereby enhancing the wear resistance of the plastic bucket.

[0037] The working principle of the anti-impact and wear-resistant plastic bucket is as follows:

[0038] Since part of the barrel body structure of the plastic bucket is composed of the elastic telescopic sleeve 2, when the top of the plastic bucket is subjected to downward pressure, the elastic telescopic sleeve 2 can be folded and stored, so that the plastic bucket offsets part of the impact force by elastic deformation, avoids stress concentration on the barrel body 1, greatly enhances the impact resistance of the plastic bucket, and the reinforcing column 4 is annularly distributed and connected with the barrel cover 11 and the annular piston 5, which not only protects the elastic telescopic sleeve 2 from overloading compression, but also disperses the impact force through rigid support to achieve the anti-impact effect of "harmony of rigidity and flexibility".

[0039] When the top of the plastic bucket is subjected to downward pressure to drive the elastic telescopic sleeve 2 to shrink, the reinforcing column 4 compresses the inert gas stored in the hollow annular cavity 1a by using the annular piston 5, thereby further improving the impact resistance of the plastic bucket, and the inert gas in the hollow annular cavity 1a flows into the annular air bag 3 after being extruded, so that the annular air bag 3 is inflated, and the inflated annular air bag 3 can improve the impact resistance of the barrel body of the plastic bucket.

[0040] The above merely illustrates the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which are made by using the content of the present application specification and drawings, are also included in the patent protection scope of the present application.
