Description

Technical Field

[0001] This utility model relates to the field of barrel screw technology, specifically a barrel screw that is easy to install. Background Technology

[0002] A barrel screw is a mechanical part mainly used in rotary machinery, serving the functions of rotation and fixation. Generally, a barrel screw consists of two parts: the screw and the body. Barrel screws are widely used in industries such as machinery, chemical, power, transportation, and light industry. For example, they can be used in various mechanical equipment such as robots, paper machines, plastic machinery, mining machinery, and printing presses.

[0003] For example, the utility model with application number CN202320637267.6 provides a screw barrel for an injection molding machine. After the raw materials and additives are melted in the melting section, they are diverted through the first and second grooves on the first mixing section, then mixed in the homogenization section, and then stirred and diverted by the diamond-shaped protrusions on the second mixing section. This makes the mixture more uniform after multiple diversions and mixing, thus improving the quality of the product. However, the existing screw barrel and connecting rod are generally integrally molded and cannot be disassembled separately. The rod is too long during installation, which makes installation inconvenient.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a barrel screw that is easy to install. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a conveniently installed barrel screw, comprising a screw body and an auxiliary component. The end of the screw body is connected to a rod head. The auxiliary component for convenient installation of the screw body is disposed outside the screw body, and the auxiliary component includes a retaining ring, a support sleeve, a mounting hole, an auxiliary rod, and an auxiliary ring. The left end of the retaining ring is connected to the support sleeve, and the right side of the retaining ring has a mounting hole. The auxiliary rod is installed inside the mounting hole, and the auxiliary ring is disposed outside the auxiliary rod.

[0007] Furthermore, the retaining ring and the sleeve are fixedly connected, and the retaining ring and the mounting hole are an integrated structure.

[0008] Furthermore, the mounting hole and the auxiliary rod are engaged, and the auxiliary rod and the auxiliary ring are sleeved.

[0009] Furthermore, an over-rubber ring is provided on the outside of the end of the screw body, and a plate is provided on the side of the over-rubber ring.

[0010] Furthermore, the surface of the rod head is provided with a material passage hole, and the rod head and the material passage hole are an integrated structure.

[0011] Furthermore, the end of the screw body is provided with an assembly hole, and the interior of the assembly hole is provided with a fixing component for connection and reinforcement.

[0012] Furthermore, the fixing component includes a fixing hole and a fixing rod, and the fixing hole is provided with a fixing rod inside.

[0013] Furthermore, an assembly block is installed on the internal thread of the assembly hole, and a connection hole is provided on the surface of the assembly block.

[0014] This utility model provides a conveniently installed barrel screw, which has the following advantages:

[0015] 1. In this utility model, the snap-fit ​​ring is fitted onto the end of the cylinder during the installation of the screw body. The support sleeve supports the screw body during installation. The mounting hole is used for quick insertion of the auxiliary rod. The auxiliary ring is quickly installed on the outside of the auxiliary rod, making disassembly and assembly simple and easy to operate. At this time, the external part of the auxiliary rod, together with the support of the snap-fit ​​ring, facilitates the screw body to enter the cylinder to complete the installation.

[0016] 2. This utility model uses assembly holes and assembly blocks with threaded connections for assembling multi-section screw bodies, allowing the screw body to be installed in sections, reducing the weight during installation and increasing convenience. The fixing rod is inserted into the fixing hole and connecting hole after the assembly block is installed, increasing the assembly firmness of the assembly hole and assembly block.
