Description

Technical Field

[0001] The utility model relates to a thermal protector, in particular to a patch type thermal protector. Background Art

[0002] The thermal protector is composed of two pieces of different alloys. When current passes through it, it will generate heat. Due to the different thermal expansion coefficients of the two alloys, the alloys will inevitably bend in one direction. When the contacts are separated, the power is cut off, which can protect electrical equipment:

[0003] The need for an adjustable mounting device may increase installation complexity, especially when frequent adjustments are required between circuit boards of different sizes or shapes. This may increase assembly time and cost. Furthermore, installing the thermal protector with gaps in its position may cause the thermal protector to become unstable or accidentally shifted, affecting its normal function.

[0004] It should be noted that the above content falls within the technical cognition of the utility model applicant and does not necessarily constitute prior art. Utility Model Content

[0005] In order to solve the above problems, the purpose of this utility model is to provide a patch type thermal protector.

[0006] To achieve the above-mentioned purpose, the present invention proposes a patch-type thermal protector, comprising a connecting frame:

[0007] A thermal protector is provided on the top of the connecting frame;

[0008] One side of the connecting frame is fixedly connected to the top of one side of the U-shaped frame through a connecting truss, and sliding grooves are opened on both sides of the inner wall of the U-shaped frame, and sliders are slidably provided inside the two sliding grooves. Connecting seats are fixed on both sides of the bottom end of the U-shaped frame, and screws are rotatably provided on the tops of the two connecting seats. The two screws are threadedly connected to the screw holes inside the corresponding sliders, and the tops of the two screws pass through the U-shaped frame and are fixedly connected to the corresponding knob bottoms. The two sliders are fixedly connected to the two ends of the cross frame through the fixing frame, and a clamping plate is fixed on one side of the cross frame.

[0009] In one example, buffer columns are fixedly provided at the four corner positions of the top of the fixing plate, the tops of the four buffer columns are fixedly connected to the bottom ends of the corresponding connecting seats, and the four connecting seats are fixedly provided on both sides of the two ends of the fixing plate.

[0010] In one example, a plurality of fitting sponges matching the width of the clamping plate are fixedly provided on the top end of the clamping plate.

[0011] In one example, the outer walls of the two knobs are provided with anti-slip grooves.

[0012] In one example, the outer wall of the U-shaped frame is provided with scale lines.

[0013] The patch-type thermal protector proposed by the utility model can bring the following beneficial effects:

[0014] The utility model uses a connecting frame, a thermal protector, a connecting truss, a U-shaped frame, a connecting seat, a clamping plate, a cross frame, a screw, a slide groove, a slider, a knob, a connecting seat, a fitting sponge, a clamping plate and a buffer column. The knob drives the screw to rotate, and the screw drives the slider to move up and down during the rotation process. The clamping plate limits and fixes the bottom of the circuit board during the upward process. The thermal protector can be quickly installed through the action of the buffer column and the clamping plate. This structure can firmly fix the thermal protector to circuit boards or equipment of different sizes, shapes and types, providing greater flexibility. BRIEF DESCRIPTION OF THE DRAWINGS
