In order to better understand the above-mentioned embodiment, the following describes it in detail in conjunction with the related drawings and Embodiment 2. The following embodiments provide a handle with a locking function that can be used as a handle for insertion and extraction. The handle has high strength, unique shape, simple structure, good feel and appearance, and the most important thing is that the handle can be used in both positive and negative states, and both have good appearance and feel. The main design idea of the following embodiments is: a handle with a locking function, including: a handle, a hook, a spring and a rotating shaft. The hook is fixed on the handle through the interference fit of the rotating shaft, and the spring is fixed in the slot of the hook and the rotating shaft. There are threaded holes and positioning posts on the handle, and there are countersunk holes on the end surface, so that the handle can be assembled on the shell by countersunk screws or fixed by combination screws.

The handle of this embodiment includes:

The hook 10 (that is, the hook structure 10) includes a locked slot 12 and an unlocked boss 15 (see Figure 4a). The boss is provided with a wave-shaped concave part to increase the feel of the handle; meanwhile, it is symmetrical The structure not only enhances the appearance, but also takes into account that the handle has a good feel when it is used in front and back. The spring fixing groove 13 (see FIG. 4b ), the spring fixing post 14 (see FIG. 4b ) and the assembly hole 11 (as shown in FIG. 2 ) are used for assembling with the rotating shaft 30 and the handle 20 . After the hook 10 and the handle 20 are assembled through the rotating shaft 30 , they can be rotated through the rotating shaft 30 . There is a limit groove 25 on the handle 20, so that when the handle is in a free state, it ensures that the hook 10 maintains an initial horizontal state. When unlocking, the hook 10 rotates with the rotating shaft 30 as the fulcrum until the end face 16 on the hook 10 contacts the groove 26 of the handle, which acts as a limit to the rotation of the hook 10, thereby stopping the rotation and achieving the purpose of unlocking .

The handle 20 structurally includes two threaded holes 23, a positioning column 24, a spring fixing column 22, an assembly hole 21 with the hook 10, a limit groove 25 when the hook 10 is in a free state, and a limit when the hook rotates. Groove 26, the whole handle 20 has sharp edges and corners, and the shape is concise.

The rotating shaft 30 structurally includes a knurled part at the tail, which can ensure an interference fit when assembling with the handle.

For the spring 40, the elastic constant of the spring 40 is determined according to the feel and comfort of actual use.

The assembly and working steps of the handle of the present embodiment are as follows:

As shown in Figures 2 and 5b, the hook 10 is assembled through the interference fit between the rotating shaft 30 and the handle 20, and the spring 40 passes through the spring fixing column 14 and the spring fixing column 22, and is clamped on the spring fixing groove 13; the handle The limit groove 25 on the 20 ensures the initial horizontal state of the hook, and also ensures that the hook 10 has only one movement direction, that is, the downward unlocking direction. The limit slot 26 on the handle 20 ensures the maximum rotation angle of the hook 10 when it rotates.

As shown in Figure 5a and Figure 5b, according to the threaded hole 23 on the handle 20 and the positioning column 24, it is assembled on the module. Insert and remove the module.

Under the condition that the direction of holding the handle is consistent, turn its assembly direction (see schematic diagrams in Figure 7 and Figure 8), and the handle has a good unlocking feel.

As shown in FIG. 9 , the handle 90 in this embodiment installs the module 92 to be plugged into the subrack 91 .

From the above embodiments, it can be seen that the embodiments of the present invention have achieved the following beneficial effects:

The handle provided by the embodiment of the utility model simplifies the design of the handle, and uses a simple structure to realize the functions of locking and plugging. Unlike conventional handles installed on panels, it is especially suitable for modules with high integration and compact space, such as fan modules, power modules, etc.

The above are only preferred embodiments of the utility model, and are not intended to limit the utility model.
