Description

A fixed structure for the control circuit board of an induction cooker

technical field

The utility model relates to a fixing structure of a control circuit board of an electromagnetic cooker, in particular to a fixing structure of a control circuit board installed on the upper cover of the electromagnetic cooker, which belongs to the improvement technology of the electromagnetic cooker.

Background technique

The fixing method of the control circuit board of the commercially available induction cooker generally adopts screw fastening at present. As shown in FIG. 1 , the screws 3 pass through the mounting holes 23 of the control circuit board 2 of the induction cooker, and the control circuit board is fixed on the support mounting column 13 provided inside the upper cover 1 . During production, workers need to use electric screwdrivers or other tools to fasten the screws on the upper cover. The entire assembly process takes longer hours, lower production efficiency, and higher labor costs and fixed costs.

Contents of the invention

The purpose of the utility model is to provide a fixing structure for the control circuit board of an induction cooker with simple structure, high production efficiency and low cost in consideration of the above problems.

The technical scheme of the utility model is: a fixed structure for the control circuit board of the induction cooker, including the upper cover of the induction cooker and the control circuit board, which is characterized in that there are two or more elastic buckles and two There are two or more limit support columns on the control circuit board corresponding to the limit support columns. Align the limit holes with the limit support columns and press the control circuit board in place to make it snap on the elastic card. buckle inside.

The elastic buckle and the limit support column are made integrally with the upper cover of the induction cooker, or are made separately and then fixed together.

The elastic buckle located in the middle of the circuit board installation area is a two-way outward buckle, the elastic buckle located around the circuit board installation area is a one-way buckle, and the elastic buckle in the middle of the corresponding circuit board installation area on the control circuit board is set There are through holes.

The position-limiting support column is a convex-shaped cylinder, and its top column passes through the position-limiting hole and is flush with or slightly higher than the upper surface of the control circuit board.

When the utility model installs the control circuit board, the worker aligns the limit hole with the limit support column and presses it, and the control circuit board makes the elastic buckle bounce off and return to make it fasten on the step of the limit support column, and the position limit The support column defines the fixed height of the control circuit board, and the two-way outward elastic buckle in the middle and the one-way elastic buckle around the periphery fix the control circuit board in place. This fixing structure is not only quick and convenient to install but also firm to fix, and also greatly saves labor costs and fixing costs.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Example:

As shown in Fig. 2, Fig. 3, Fig. 4 and Fig. 5, the fixed structure of the control circuit board of the electromagnetic oven of the present invention includes the upper cover of the electromagnetic oven 1 and the control circuit board 2, and the installation area of the control circuit board inside the upper cover of the electromagnetic oven 1 is provided with two One or more elastic buckles 11 and two or more limit support columns 12, the corresponding limit support columns 12 on the control circuit board 2 are provided with two or more limit holes 21, and the limit holes 21 are aligned with the limit support post 12 and press the control circuit board 2 into place so that it is snapped into the elastic buckle 11.

In this embodiment, the inner side of the upper cover 1 of the induction cooker corresponds to the four corners and the central part of the control circuit board 2. A limit support column 12 is respectively provided; There is one elastic buckle on the outside of each side, and there are two sets of elastic buckles corresponding to the central part of the control circuit board. Each set of elastic buckles is composed of two elastic buckles with hooks arranged in parallel and facing outward; as shown in Figure 5 As shown, the control circuit board 2 is provided with five limit holes 21 corresponding to the five limit support columns, and the middle part is provided with two through holes 22 corresponding to two sets of elastic buckles. The above-mentioned limit support column 12 is a convex-shaped cylinder, and its top column passes through the limit hole 21 and is flush with or slightly higher than the upper surface of the control circuit board 2. The limit support column defines the fixed height of the control circuit board.

The above-mentioned elastic buckle 11 and the limit support column 12 are made integrally with the upper cover 1 of the induction cooker, or are made separately and then fixed together. In this embodiment, for the convenience of processing, the elastic buckle 11, the limit support column 12 and the upper cover 1 of the induction cooker are made integrally.

When installing the control circuit board, the worker aligns the limit hole with the limit support column and presses it, and the control circuit board makes the elastic buckle bounce and return to make it fasten on the step of the limit support column. In order to ensure the fixed height of the control circuit board, the two-way outward elastic buckle in the middle and the one-way elastic buckle around the periphery fix the control circuit board in place.
