At present, some of the snap-action protectors are combined and connected with a thermostat. As Figure 1 shown, by opening an assembly opening 2 on the heat conduction bracket 1 of the thermostat, when assembling, the snap-action protector 3 is aligned with the assembly opening 2 and then pressed down by brute force. If the operation is improper, the pressing will be uneven, and some positions cannot be pressed in place, and the installation is extremely inconvenient and time-consuming, thus reducing the production efficiency.

[0021] The present utility model will be further described below with reference to the drawings and embodiments.

[0022] As Figures 1 to 5As shown in the figure, a combined structure of a snap-action protector 2 and a thermostat includes an upper coupling base 1 and a snap-action protector 2. A heat-conducting bracket 3 is connected to the top end of the upper coupling base 1. The heat-conducting bracket 3 integrally extends laterally with a connecting bracket 4. A clamping opening 401 is formed in the connecting bracket 4. An open opening 402 is formed on one side of the clamping opening 401. The snap-action protector 2 is laterally clamped into the clamping opening 401 through the open opening 402.

[0023] This thermostat can combine and connect the snap-action protector 2 into a whole through the connecting bracket 4, enabling modular installation. And with the quick installation structure of the clamping opening 401, the snap-action protector 2 is fixed by being laterally inserted and clamped into the clamping opening 401. The installation structure is simple, which can improve production efficiency and is convenient for operation.

[0024] Arc-shaped recesses 403 are formed in the middle of the inner walls on the opposite sides of the clamping opening 401. The snap-action protector 2 is clamped at the middle position of the clamping opening 401 through the two arc-shaped recesses 403 and is separated from the bottom inner wall of the clamping opening 401 to form a clearance area A. The purpose of forming the clearance area A is to reduce the friction between the snap-action protector 2 and the connecting bracket 4. At the same time, the arc-shaped recesses 403 match the outer surface shape of the snap-action protector 2, which can ensure the effectiveness of the clamping.

[0025] A number of limiting convex blocks extend from the inner wall of the clearance area A, and the number of limiting convex blocks abut or lean against the outer surface of the snap-action protector 2. The limiting convex blocks can limit the insertion depth of the snap-action protector 2 to ensure that the snap-action protector 2 is clamped between the two arc-shaped recesses 403.

[0026] In this embodiment, the number of limiting convex blocks includes a middle limiting block 41 and two side limiting blocks 42. The middle limiting block 41 is connected to the middle position of the bottom inner wall of the clamping opening 401, and the two side limiting blocks 42 are respectively connected to the inner walls on the corresponding sides of the clearance area A of the clamping opening 401 and extend oppositely. The middle limiting block 41 and the two side limiting blocks 42 can be evenly distributed in the clearance area A.

[0027] One side of the connecting bracket 4 is connected with a transition connecting frame 5 formed by continuous bending into a "concave" structure. The connecting bracket 4 is integrally connected with the heat-conducting bracket 3 through the transition connecting frame 5. This structure makes the connecting bracket 4 have a certain elasticity by using the transition connecting frame 5 to ensure that the temperature-sensing surface of the snap-action protector 2 can be pressed against the heating plate.

[0028] The connecting bracket 4 is provided with reinforcing ribs 43 on the left and right sides of the clamping opening 401. The reinforcing ribs 43 extend along the installation and removal direction of the snap-action protector 2, and the reinforcing ribs 43 are integrally formed with the connecting bracket 4 by stamping. The reinforcing ribs 43 can increase the strength of the connecting bracket 4 and will not be deformed or distorted by extrusion during the assembly process of the snap-action protector 2.

[0029] Two limiting parts 44 extend from the open opening 402, and the limiting parts 44 extend oppositely; the two limiting parts 44 can prevent the snap-action protector 2 from sliding out horizontally through the open opening 402.

[0030] A connecting hole 501 is formed on the base of the transition connecting frame 5; the connecting hole 501 is mainly used for firmly connecting the thermostat to the heating plate.

[0031] A wire circuit is arranged on the upper coupling base 1, and a dry-burning prevention switch is connected in series on the wire circuit. A dry-burning prevention device is installed on the heat conduction bracket 3, and the dry-burning prevention device is adjacent to or abuts against the dry-burning prevention switch;

[0032] The dry-burning prevention switch mainly includes a moving contact piece 61 and a static contact piece 62 that elastically touch each other. The moving contact piece 61 and the static contact piece 62 are connected in series on the wire circuit. The dry-burning prevention device includes a bimetallic strip 71 and an insulating rod 72. The bimetallic strip 71 is fixed on the connecting bracket 4, and the insulating rod 72 is slidably connected in the upper coupling base 1 and is placed between the moving contact piece 61 and the bimetallic strip 71.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
