Description

Technical Field

[0001] The utility model belongs to the technical field of double-insurance temperature sensors, in particular to a double-insurance thermistor temperature sensor device. Background Art

[0002] The thermistor temperature sensor is equipped with a thermal fuse that cuts off the power supply when the temperature exceeds the limit to avoid fire. However, a thermistor temperature sensor with a single thermal fuse will fail when the thermal fuse fails. Therefore, a double-insurance thermistor temperature sensor with two thermal fuses is required.

[0003] The existing double fuses are all installed inside the housing of the thermistor temperature sensor. When the fuse inside the temperature sensor needs to be checked or replaced, the housing of the temperature sensor needs to be disassembled and then the fuse needs to be checked, which is very inconvenient. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a double insurance thermistor temperature sensor device.

[0005] To achieve the above-mentioned purpose, the utility model proposes a double-insurance thermistor temperature sensor device, including a circular shell, a fixing seat fixedly connected to the inside of the circular shell, mounting components are provided on both sides of the fixing seat, and the mounting components are used to install a fuse. A square through groove is provided on the outer side of the circular shell near the mounting component, and an arc-shaped baffle is rotatably connected in the square through groove. The center of the arc-shaped baffle and the circular shell are on the same axis, a spiral groove is provided on one side of the circular shell and the arc-shaped baffle, and the spiral grooves on the circular shell and the arc-shaped baffle cooperate with each other, and the outer side of the circular shell is threadedly connected to a rotating ring.

[0006] In one example, the mounting assembly includes two support plates, which are fixedly connected to the mounting plate. A slide groove is provided on opposite sides of the two support plates, and a slider is slidably connected in the slide groove. The mounting plate is fixedly connected between the two sliders, and a fuse is installed on one side of the mounting plate.

[0007] In one example, the side surfaces of the mounting plate located on both sides of the fuse are provided with line fixing assemblies, and the line fixing assemblies include a fixing plate, the fixing plate is fixedly connected to the mounting plate, one side of the fixing plate is fixedly connected to a support seat, the upper surface of the support seat is fixedly connected to a pallet, two through holes are provided on the pallet, bolts are slidably connected in the through holes, and the upper ends of the bolts are fixedly connected to a rubber plate.

[0008] In one example, the inner side of the arc-shaped baffle is fixedly connected to a support rod, one end of the support rod is fixedly connected to an arc-shaped extrusion plate, and a spring is fixedly connected between the arc-shaped extrusion plate, the slider and the slide groove.

[0009] In one example, the arc-shaped baffle, support rod, arc-shaped extrusion plate, and rotating ring are all made of heat-conducting materials.

[0010] In one example, the outer side of the rotating ring is fixedly connected to a heat dissipation ring.

[0011] The dual-insurance thermistor temperature sensor device proposed by the utility model can bring the following beneficial effects:

[0012] First, by setting the arc-shaped baffle, when the fuse is inspected or replaced, the rotating ring is rotated to expose the arc-shaped baffle.

Two fuses are fixedly installed inside the circular shell 1 through the installation component 3. The fuse is connected to the thermistor and other components through wires to form a double insurance. When the fuse is inspected or replaced, the rotating ring 5 is rotated to expose the arc-shaped baffle 4. At this time, the two arc-shaped baffles 4 on the outer side of the circular shell 1 are opened to expose the internal installation component 3 and the fuse. The staff does not need to disassemble the temperature sensor shell for inspection, which makes inspection more convenient and saves time.

[0027] Specifically, the mounting assembly 3 includes two support plates 31, which are fixedly connected to the mounting plate 33. A slide groove is provided on the opposite side of the two support plates 31, and a slider 32 is slidably connected in the slide groove. The mounting plate 33 is fixedly connected between the two sliders 32. A fuse is installed on one side of the mounting plate 33, and the fuse is fixed on the mounting plate 33. The mounting plate 33 is slidably set inside the circular shell 1. When the fuse is inspected, the arc baffle 4 is opened at this time, and the mounting plate 33 is pulled to move the mounting plate 33 along the slide groove to the square through groove, close to the square through groove, so as to facilitate the inspection of the fuse on the mounting plate 33.
