A fan module, comprising a panel frame, one end of the panel frame is provided with a rotatable locking block, one side of the locking block is provided with a locking structure adapted to the fan frame, and the panel frame is provided with There is a handle that drives the locking block to rotate.

In the above-mentioned fan module, the locking block is connected with the boss on the inner side of the panel through a rotating pin, one side of the locking block is an arc edge, and the locking structure is composed of ejection teeth and pressing teeth arranged on the arc edge One end of the handle is the first arc-shaped splint and the second arc-shaped splint clamped on the upper and lower frames of the panel frame, and the ends of the first arc-shaped splint and the second arc-shaped splint They are respectively connected to the side surfaces of the locking blocks, and the other end of the handle is connected to a hook through a revolving pin and a spring, and a fastening hole corresponding to the hook is provided on the panel frame.

For the fan module provided by the utility model, by setting the pressing teeth and ejecting teeth coupled with the side wall of the cabinet frame on the locking block of the panel frame, when the fan module is pushed into the fan frame, it only needs to be connected with the Pull out the handle connected to the locking block from the panel, and then push the fan module into the fan frame. After it is inserted in place, turn the handle. Guided by the blind plug at the rear of the fan frame, the fan module is installed in place, thus completing the installation and locking of the fan module.

The utility model has the following advantages: in the process of inserting and dismounting the fan module, the fan module can be automatically installed or taken out only by the interaction between the mating surfaces, no screw connection is used, and the installation and removal process is convenient Fast, the use of this locking structure can greatly improve the operability and maintainability under the premise of satisfying the function, and at the same time leave room for creativity in the appearance of the fan module.

Detailed ways

As shown in Fig. 1, Fig. 3 and Fig. 4, the utility model provides a fan module 2 connected with the positioning structure of the slideway side wall of the frame body 1. The fan module 2 consists of a fan upper cover 6, a fan lower cover 7 and a panel 8 One end of the panel frame body 81 of the panel 8 is provided with a rotatable locking block 16, and one side of the locking block 16 is provided with a locking structure coupled with the positioning structure of the side wall slideway of the cabinet fan frame. The body 81 is provided with a handle 9 that can drive the locking block to rotate. By turning the handle 9, the fan module 2 can be locked in the fan frame 1 or taken out from the fan frame 1, which is convenient and quick to install and disassemble.

As shown in Figures 2, 3, 4, and 5, a boss 83 is provided inside the panel frame body 81, a connecting through hole 86 is provided on the boss 83, and a groove is opened in the middle of the boss 83, and the locking block 16 passes through The rotating pin is installed in this groove. One side of the locking block 16 is an arc edge. A typical locking structure is formed by ejecting teeth 18 and pressing teeth 17 arranged at intervals on the arc edge. The handle 9 includes two clips The first arc clamping plate 91 and the second arc clamping plate 92 installed on the upper and lower frames of the panel frame body 81, one end of the first arc clamping plate 91 and the second arc clamping plate 92 are connected with the two ends of the locking block 16 respectively.
