It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0026] like Figure 1 As shown, this embodiment provides a metal fixed connection structure, including a metal component 1 and a metal rod 2. The metal component 1 is provided with a first through hole 101. A metal ring 21 is provided at the end of the metal rod 2. A support part 3 is provided in the first through hole 101. When the metal rod 2 is inserted into the first through hole 101, the support part 3 is embedded in the metal ring 21 and expands the metal ring 21, so that the metal ring 21 is fixed on the support part 3 and the inner wall of the first through hole 101. The support part 3 is provided with a bevel 31 facing the end of the metal rod 2. By stamping, the metal ring 21 at the end of the metal rod 2 is expanded by the support part 3, so that the metal ring 21 is clamped between the support part 3 and the inner wall of the first through hole 101, thereby fixing it. This does not require drilling holes or inserting pins or screws on the side, which improves work efficiency and makes installation more convenient.
[0027] like Figure 2-3 As shown, in one optional embodiment, the support 3 is a spherical structure. The metal ring 21 can be placed at any position on the surface of the spherical structure. The diameter of the spherical structure should be slightly larger than the metal ring 21 so that the metal ring 21 can be expanded during stamping. The diameter of the first through hole 101 should be larger than the diameter of the spherical structure. The distance between the spherical structure and the inner wall of the first through hole 101 should be less than the wall thickness of the metal ring 21. In this way, the metal ring 21 will be clamped more firmly when it expands.
[0028] like Figure 4As shown, in an optional second embodiment, the support part 3 is a cylindrical structure with a bevel 31 on the cylindrical structure facing the end of the metal rod 2, which facilitates the metal ring 21 to wrap around the support part 3 along the bevel 31. The diameter of the first through hole 101 should be larger than the diameter of the cylindrical structure, and the distance between the cylindrical structure and the inner wall of the first through hole 101 should be smaller than the wall thickness of the metal ring 21, so that the metal ring 21 will be clamped more firmly when it expands.
[0029] As an optional embodiment, the metal rod 3 is fixed to the metal ring 21 on the inner wall of the support part 3 and the first through hole 101 by stamping, which can be achieved by applying a certain pressure to the metal rod 3.
[0030] like Figure 5 As shown, as an optional second embodiment, this embodiment provides a locking tongue. In the metal fixed connection structure of the first aspect utility model, the metal component is the locking tongue body. The locking tongue body is mainly installed in the lock body and extends and retracts in the lock body. The locking tongue body is generally fixed by means of pins or screws. Therefore, this method is relatively cumbersome and inconvenient to install. By using a stamped metal rod 2, the metal ring 21 is clamped between the support part 3 and the inner wall of the first through hole 101 to improve the installation efficiency.
[0031] like Figure 6 As shown, as an optional third embodiment, this embodiment provides a handle. In the first aspect, the utility model has a metal fixed connection structure. The metal component is the handle body. The handle body is used to be installed on the door to open the door lock. Therefore, the metal ring 21 can be clamped between the support part 3 and the inner wall of the first through hole 101 by stamping the metal rod 2 to improve the installation efficiency.
[0032] Working principle: A first through hole 101 is formed by opening or drilling on the metal part 1 as needed; the support part 3 is placed into the first through hole 101; the metal rod 2 is inserted into the first through hole 101; the metal rod 2 is stamped so that the support part 3 is embedded in the metal ring 21, and the metal ring 21 is expanded and pressed against the inner wall of the first through hole 101 for fixation. In this way, the metal rod 2 can be easily fixed in the first through hole 101 of the metal part 1.
[0033] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited thereto. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model are equivalent substitutions and are included within the protection scope of the present utility model.
