Description

Technical Field

[0001] This utility model relates to the field of handle structure processing, specifically a three-section concealed connection aluminum alloy handle. Background Technology

[0002] Handles are installed on the door covers of furniture and home appliances. Aluminum alloy handles have many advantages such as being lightweight, beautiful, and corrosion-resistant, and are commonly found on high-end furniture and home appliances.

[0003] Conventional aluminum alloy handles can be divided into one-piece structures or multi-segment structures. One-piece handles are fixed to the door cover at both ends with screws or bolts. One-piece handles are typically smaller and simpler in design, but the exposed connectors affect aesthetics, and the entire handle must be replaced if damaged. Multi-segment handles, on the other hand, are composed of multiple segments, allowing for more diverse designs and longer lengths. Furthermore, each component can be replaced and repaired individually, reducing maintenance costs.

[0004] However, the existing multi-section handle connection sections are not secure and are prone to loosening and falling off; in addition, the threaded fasteners are exposed, which is not only unsightly but also prone to rust and has a short service life. Summary of the Invention

[0005] This utility model provides a three-section concealed connection aluminum alloy handle. The handle is composed of three sections, each of which is made of aluminum profile. The connection structure at the connection section is firm and reliable, and the threaded fasteners are not exposed under stress, but are hidden inside. The overall appearance is beautiful.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A three-section concealed connection aluminum alloy handle is provided, wherein the handle is formed by the insertion and combination of a middle section and two end sections. The surface of the end section is fixed to the mounting base by a number of screws B, wherein at least one screw B passes through the insertion section between the middle section and the end section. The inner cavity of the end section is provided with a stepped structure, and the end of the middle section matches the size of the step.

[0008] By using screw B to connect to the insertion sections of the middle and end sections, the connection structure between the middle section, end sections, and mounting base is made more stable. The three parts can be locked together using screw B, preventing relative rotation. Furthermore, during installation and disassembly, only screw B needs to be tightened to install or separate the three parts, making installation and disassembly more convenient. The stepped structure at the insertion point improves the concentricity of the installation, and there is no step difference in appearance after installation at both ends.

[0009] Screw B is installed at the bottom of the groove of the mounting base, and a cover plate is installed at the opening of the groove. The cover plate is fixedly connected to the mounting base by screw A.

[0010] The cover plate conceals the head of screw B, preventing it from being exposed and affecting its appearance, while also providing waterproofing and moisture protection, and slowing down the corrosion process of screw B.

[0011] An end cap is installed at the end of the end section. The end cap is stepped, with the small step portion embedded in the inner cavity of the end section. A guide groove is provided on the small step portion, and a matching guide flange is provided in the inner cavity of the end section.

[0012] The end cap seals the end of the handle. Through the positioning function of the guide structure, the logo on the end cap will not be misaligned or rotated, thus improving the appearance of the handle.

[0013] Advantages of this utility model:

[0014] 1. Each section of the handle of this utility model is made of aluminum profile. The surface and inner cavity of each section are smooth and the dimensions are precise. The sections are connected by plug-in, and the middle section, end section and mounting base are connected at the same time by screw B. The connection structure is stable and the installation and disassembly are more convenient.

[0015] 2. The stress-bearing threaded connector of this utility model is installed in a concealed manner, which not only makes it aesthetically pleasing, but also prevents the threaded fasteners from rusting and improves the life of the handle.

[0016] 3. The segments of this utility model are accurately positioned and will not rotate relative to each other. Attached Figure Description
