DETAILED DESCRIPTION
[0019] See attached Figures 1 to 5The utility model discloses a handle lock, comprising a lock shell 1, a handle 2, a rotating shaft 3 and a lock hook assembly 4. The rotating shaft 3 is mounted on the lock shell 1 and can be rotated. The handle 2 is mounted on the rotating shaft 3 and drives the rotating shaft 3 to rotate. The lock hook assembly 4 comprises a driven lock hook 41, a driving lock tongue 42 and a lock hook torsion spring 43. One elastic arm of the lock hook torsion spring 43 is hung on the driven lock hook 41, and the other elastic arm of the lock hook torsion spring 43 abuts on the lock shell 1. The driven lock hook 41 is configured to be mounted on the rotating shaft 3 in a manner that it can rotate relative to the rotating shaft 3. The hanging hole of the driven lock hook 41 is a circular hole, and the circular hole cooperates with the circumferential surface of the rotating shaft 3 to realize the positioning of the driven lock hook on the rotating shaft and the rotation relative to the rotating shaft, driving the lock The tongue 42 is configured to be sleeved on the rotating shaft 3 in a manner of circumferential linkage with the rotating shaft 3. An axial cross section is provided on the rotating shaft 3, and the sleeve hole 421 of the driving lock tongue 42 adopts an adaptive shape to cooperate with the axial cross section, so as to achieve rotational linkage. The driving lock tongue 42 has a toggle portion 422, and the spring force of the lock hook torsion spring 43 drives the driven lock hook 41 to rest against the toggle portion 422. The driving lock tongue 42 is provided with a lock tongue spring 44, and a lock tongue limiting wall 11 is provided on the lock housing 1. The driving lock tongue 42 is stopped and limited by the lock tongue limiting wall 11 on the other side of the driven lock hook 41. The spring force of the lock tongue spring 44 drives the driving lock tongue 42 to rest against the lock tongue limiting wall 11. In this specific embodiment, the lock tongue spring 44 preferably adopts a torsion spring design. The spring coil of the lock tongue spring 44 is mounted on the rotating shaft 3. One elastic arm of the lock tongue spring 44 is mounted on the driving lock tongue 42, and the other elastic arm of the lock tongue spring 44 abuts against the lock housing 1. This has the advantages of easy assembly and reliable driving. Based on the guidance of the present utility model, those skilled in the art combined with existing technical knowledge will know that tension spring and compression spring designs can also be used and can also be applied through adaptive structural adjustment.
[0020] The driving lock tongue 42 is a U-shaped member having two mounting arms 423, with the toggle portion 422 connected to the mounting arms 423. The driving lock tongue is easy to install and arrange, and its engagement with the driven lock hook and the lock tongue retaining wall is more stable and reliable. A lock tongue spring 44 is disposed on each of the mounting arms 423 of the driving lock tongue 42.
[0021] To facilitate the installation of the torsion spring, the driving lock tongue 42 is mounted on the rotating shaft 3 through a side hole 4211 extending laterally therefrom. The elastic arm end of the lock tongue spring 44 is bent to form a U-shaped hook head, which passes through the side hole 4211 to be hung on the driving lock tongue 42.
[0022] In this specific embodiment, the lock housing 1 includes a panel 1-1 and a mounting base 1-2. A handle groove 1-11 is recessed in the top of the panel 1-1. The mounting base 1-2 is located within the handle groove 1-11. The rotating shaft 3 is mounted on the mounting base 1-2. The mounting base 1-2 has an assembly cavity 1-21. The lock hook assembly 4 is assembled within the assembly cavity 1-21. The inner wall of the assembly cavity 1-21 is provided with the lock tongue limiting wall 11. The lock hook torsion spring 43 abuts against the wall of the assembly cavity 1-21. The mounting base design facilitates the installation and arrangement of the lock hook assembly. In the accompanying drawings, the rotating shaft 3 is designed with two connecting ends 31 and an intermediate main shaft 32. The two connecting ends 31 are connected to the ends of the intermediate main shaft 32 to achieve the installation of the rotating shaft on the mounting base 1-2.
[0023] When the driven lock hook is opened or accidentally shaken or moved, the driving lock tongue, under the force of the lock tongue spring, presses against the lock tongue limit wall and does not follow. Therefore, the handle does not shake. This solves the problem of handle noise caused by the driven lock hook being opened, shaken or moved accidentally. It is suitable for customers with noise requirements. Compared with the handle torsion spring design on the traditional handle, it has a more reliable effect of preventing abnormal noise.
