Description

Technical Field

[0001] This utility model belongs to the field of sprayer technology and relates to a blow-molded barrel. Background Technology

[0002] Currently, sprayer barrels are typically manufactured using blow molding. During manufacturing, a softened plastic preform is placed into a mold, and air is blown in to expand it and conform it to the mold cavity wall, resulting in a complete, seamless, and weld-free barrel. While the barrel offers excellent leak-proof performance and structural strength at a relatively low production cost, the limitations of the blow molding process mean that only a single, seamlessly connected hollow handle can be formed, leading to lower structural strength for the handle. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a blow-molded bucket. The technical problem this invention aims to solve is how to ensure the strength of the blow-molded bucket handle while making the connection structure between the handle and the bucket body more functional.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A blow-molded bucket includes a bucket body, characterized in that two mounting blocks are detachably connected to the bucket body and are respectively located on both sides of the opening of the bucket body; the bucket body is also provided with a handle, the two ends of which are respectively engaged with the two mounting blocks; the mounting blocks are also provided with lifting rings, and the lifting rings are all exposed above the handle.

[0006] This blow-molded bucket features detachable mounting blocks, allowing for a detachable connection between the handle and the bucket body. The bucket body is still manufactured using blow molding, while the handle can be manufactured using injection molding. This allows for the addition of reinforcing ribs and other structural features to ensure the handle's structural strength. Additionally, the hanging rings on the two mounting blocks can be used to attach carrying straps, making the connection between the handle and the bucket body more versatile.

[0007] In the aforementioned blow-molded bucket, the bucket body has a positioning block with a T-shaped cross-section, and the mounting block has a first T-shaped groove that fits the positioning block. All mounting blocks are engaged with the positioning block via the first T-shaped groove. This mating structure of the T-shaped groove and the T-shaped block enables a quick and concealed connection between the mounting block and the bucket body, and improves the stability of the connection.

[0008] In the aforementioned blow-molded bucket, the mounting block and the positioning block are respectively provided with coaxially arranged internal threaded holes, and the mounting block and the positioning block are connected by bolts that pass through both internal threaded holes. This further ensures the reliability of the connection between the mounting block and the positioning block, making the mounting block more securely connected to the bucket body.

[0009] In the aforementioned blow-molded bucket, the lifting ring is vertically positioned and integrally formed on one end of the mounting block. A first T-shaped groove is positioned adjacent to the lifting ring. The cross-section of the mounting block located between the groove wall of the first T-shaped groove and the other end of the mounting block is U-shaped. Both ends of the handle have second T-shaped grooves adapted to the mounting block, and the end of the handle is engaged with the mounting block via the second T-shaped grooves. This achieves a quick and concealed connection between the handle and the mounting block, and improves the stability of the connection.

[0010] In the aforementioned blow-molded barrel, the front end of the second T-shaped groove is closed and has a clearance hole, through which the lifting ring extends. This allows for unidirectional engagement of the handle and the mounting block, improving the stability of the engagement.

[0011] In one of the blow-molded buckets described above, a shoulder strap is also provided on the bucket body, with each end of the strap detachably connected to two hanging rings. This allows the user to install or remove the shoulder strap according to their needs.

[0012] Compared with existing technologies, the advantages of this blow-molded bucket are as follows: This blow-molded bucket achieves a detachable connection between the handle and the bucket body through detachable mounting blocks. The bucket body is still manufactured by blow molding, while the handle can be manufactured by injection molding, allowing the handle to be equipped with reinforcing ribs and other structures to ensure the structural strength of the handle. At the same time, the hanging rings on the two mounting blocks can be used to set up carrying straps, thus making the function of the connection structure between the handle and the bucket body more versatile.

Detailed Implementation

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] A blow-molded bucket, as shown Figure 1-6 The container includes a barrel body 1, on which two mounting blocks 2 are detachably connected, located on both sides of the opening of the barrel body 1. The barrel body 1 is also provided with a handle 3, with both ends of the handle 3 being respectively engaged with the two mounting blocks 2. The mounting blocks 2 are also provided with lifting rings 2a, with the lifting rings 2a protruding from the handle 3.

[0022] Reference Figure 2 and Figure 4 Specifically, the barrel body 1 has a positioning block 1a with a T-shaped cross-section, and the mounting block 2 has a first T-shaped groove 2b that is adapted to the positioning block 1a. The mounting block 2 is engaged with the positioning block 1a through the first T-shaped groove 2b.

[0023] Reference Figure 2 Furthermore, the mounting block 2 and the positioning block 1a are respectively provided with coaxially arranged internal threaded holes 4, and the mounting block 2 and the positioning block 1a are connected by bolts that pass through the internal threaded holes 4 of both.

[0024] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 More specifically, the lifting ring 2a is vertically positioned and integrally formed on one end of the mounting block 2. The first T-shaped groove 2b is adjacent to the lifting ring 2a. The cross-section of the mounting block 2 located between the groove wall of the first T-shaped groove 2b and the other end of the mounting block 2 is U-shaped. The handle 3 has second T-shaped grooves 3a at both ends that are adapted to the mounting block 2. The end of the handle 3 is engaged with the mounting block 2 through the second T-shaped grooves 3a. The engagement direction of the handle 3 with the mounting block 2 is perpendicular to the engagement direction of the mounting block 2 with the positioning block 1a.

[0025] Reference Figure 6 More specifically, the bucket body 1 is also provided with a shoulder strap 6, the two ends of which are detachably connected to two hanging rings 2a.

[0026] In this embodiment, the front end of the second T-shaped groove 3a is preferably closed and has a clearance hole 5, and the lifting ring 2a extends out of the clearance hole 5.
