[0036] Reference Figures 1-5 This is one embodiment of the handle assembly 2 of this utility model.
[0037] like Figure 2 As shown, the handle assembly 2 includes a long, narrow handle 10 and two handle seats 20. The two handle seats 20 are respectively located at both ends of the handle 10. The handle assembly 2 is fixed to an external device (such as the door 1 of a cooking appliance) via the handle seats 20. For ease of description, the length direction of the handle 10 is defined as the axial direction, and the direction perpendicular to the axial direction is defined as the radial direction. The surface of the handle 10 that mates with the handle seat 20 is called the inner surface. The opposite surface is called the outer surface.
[0038] Specifically, such as Figure 4 and Figure 5 As shown, the connection structure between the handle base 20 and the handle 10 is as follows:
[0039] Stop structure: One end of the handle base 20 has a stop portion 21. During assembly, the stop portion 21 abuts against the end face of the handle 10.
[0040] Guide structure: One or more guide ribs 22 are provided at one end of the handle seat 20 near the stop part 21, and a guide groove 11 for accommodating the guide ribs 22 is provided at the corresponding position on the handle 10.
[0041] Positioning structure: A positioning post 23 is provided at the end of the handle seat 20 away from the stop part 21, and a positioning hole 12 for cooperating with the positioning post 23 is provided at the corresponding position on the handle 10.
[0042] Fastening structure: Mounting holes 24 and 13 are provided on the handle base 20 and handle 10 respectively, and fasteners 30 pass through the mounting holes of both to lock the handle base 20 and handle 10.
[0043] The assembly process of the handle base 20 and the handle 10 is as follows:
[0044] First, the handle base 20 and the handle 10 are guided by the guide rib 22 and the guide groove 11, achieving initial guidance and circumferential limiting (anti-rotation) during assembly, ensuring that the handle base 20 will not be angularly misaligned. Next, the positioning pin 23 is inserted into the positioning hole 12, achieving axial and radial positioning. Simultaneously, the stop 21 on the handle base 20 abuts against the end face of the handle 10, further restricting the relative movement of the handle base 20 in the axial direction. Finally, it is secured with fasteners 30 such as screws.
[0045] The handle assembly 2 described above achieves initial guidance and positioning during the assembly process through the guiding structure of the guide groove 11 and guide rib 22 on the handle seat 20. Then, it is further positioned through the positioning structure of the positioning post 23 and positioning hole 12 and the stopping structure of the stop part 21, which ensures the positional accuracy of the handle seat 20 during the installation process, improves product consistency, and increases assembly efficiency.
[0046] In some embodiments of this application, such as Figure 5 As shown, one end of the guide groove 11 opens onto the end face of the handle 10, forming an open notch structure at the end of the handle 10. This open guide groove 11 structure simplifies the assembly process. During assembly, there is no need to painstakingly align the guide rib 22 with a closed slot; instead, the guide rib 22 can be directly slid into the guide groove 11 from the end face of the handle 10, achieving quick alignment and preventing mistaken alignment.
[0047] Furthermore, the guide groove 11 extends along the length (axial direction) of the handle 10, and the closed end (the non-open end) of the guide groove 11 is semi-circular. The guide rib 22 is adapted to the shape of the guide groove. The axial extension of the guide groove 11 ensures that the handle seat 20 is assembled along a straight path. The semi-circular design of the closed end of the guide groove 11 can effectively disperse stress and prevent stress concentration at the end of the groove, thereby improving the structural strength of the connection area of the handle 10.
[0048] In some embodiments of this application, the positioning hole 12 is an oblong hole, and the long axis of the oblong hole extends along the length direction (axial direction) of the handle 10. The short axis of the oblong hole fits tightly with the positioning post 23, ensuring positioning accuracy. At the same time, the long axis of the oblong hole can compensate for minor length errors that may occur during the manufacturing process of the parts, ensuring that assembly can be completed smoothly even if there are slight deviations in the size of the parts.
[0049] In some embodiments of this application, the handle 10 is a one-piece molded hollow metal extrusion. The handle 10 has an internal hollow cavity, which significantly reduces its weight while ensuring sufficient strength, thus saving material costs. Preferably, the handle 10 has an arc-shaped structure; the arc design better conforms to the natural curve of the human hand when gripping, providing a more comfortable grip.
[0050] In some embodiments of this application, after the handle base 20 is assembled with the handle 10, the stop portion 21 can close the hollow cavity at the end of the handle 10. The stop portion 21 acts as a cover, closing the originally exposed opening of the hollow cavity, making the handle more aesthetically pleasing, while avoiding exposed sharp cuts.
[0051] Furthermore, after assembly, the outer contour of the handle base 20 smoothly transitions with the outer contour of the handle 10. This means that the two sides of the handle base 20 and the end face of the stop portion 21 are flush with the two sides and outer surface of the handle 10, making the handle base 20 and the handle 10 visually integrated and improving the overall aesthetics of the product.
[0052] In some embodiments of this application, the two handle seats 20 have identical structures and are symmetrically arranged about the center of the handle 10. That is, the two handle seats 20 are interchangeable parts, and there is no need to distinguish between the left and right handle seats 20 during installation, eliminating the risk of misassembly. At the same time, a single mold can be used for manufacturing, reducing production costs.
[0053] In some embodiments of this application, the guide groove 11, the mounting hole 13 of the handle 10, and the positioning hole 12 are arranged sequentially along the length of the handle 10. This layout rationally separates different functional structures (guiding, positioning, and fastening) within the connection area, resulting in a more uniform distribution of connection stress and preventing stress concentration in a small area. This enhances the stability and reliability of the entire connection structure. Preferably, the handle 10 may be provided with two mounting holes 13 to enhance the connection fastening.
[0054] The handle base 20 is a one-piece molded plastic part. The plastic part can form a heat insulation structure to prevent heat from the door body 1 from being transferred to the handle 10, avoid high temperature burns, and improve the safety of equipment use.
[0055] This utility model also includes a cooking device, such as an oven or microwave oven. The cooking device includes a housing and a door 1, and the door 1 is provided with the aforementioned handle assembly 2.
[0056] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
