[0002] A temperature detector, also known as a point-type temperature-sensitive fire detector, is a fire detector that responds to temperature changes around a certain point or line in the warning range.

[0003] A Chinese patent discloses a temperature detector (authorization announcement number CN212903629U). In this patented technology, the airflow around the temperature detector enters the shell through the vent hole, and then reaches the thermistor under the guidance of the guide plate. The thermistor senses the temperature, thereby realizing fire detection. The setting of the guide plate allows the airflow to reach the thermistor faster and more accurately, thereby improving the accuracy and sensitivity of the temperature sensing of the temperature detector.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the base of the existing temperature detector is connected to the temperature detector by wires, and the base needs to be fixed first during the installation process. During the process of fixing the base, the temperature detector may be pulled, causing the connecting wire between the base and the temperature detector to be disconnected, causing damage to the equipment.

[0023] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0024] Reference Figure 1 - Figure 4 As shown, the utility model provides a technical solution: an electronic temperature detector, including a base 1, four mounting holes 2 are opened on the top of the base 1, a threading hole 3 is opened on the top of the base 1, a temperature detector body 4 is installed at the bottom of the base 1, two limiting round rods 5 are fixedly connected to the top of the base 1, and a spring 6 is slidably connected to the surface of the limiting round rod 5. The top of the spring 6 is fixedly connected to a wiring terminal 8, and the bottom of the wiring terminal 8 is fixedly connected to a first conductive sheet 9, and the bottom of the first conductive sheet 9 is exposed from the bottom of the spring 6. The top of the temperature detector body 4 is installed with a first conductive sheet 9. Second conductive sheet 19, the user passes the wire through the threading hole 3 to the inside of the base 1 and connects it to the terminal 8, passes the screw through the inside of the mounting hole 2 and fixes it to the wall, aligns the second conductive sheet 19 with the position of the first conductive sheet 9, and then installs the temperature sensing detector body 4 into the inside of the base 1. The elasticity of the spring sheet 6 makes the second conductive sheet 19 fit tightly with the first conductive sheet 9, so that the temperature sensing detector body 4 is energized. The second conductive sheet 19 is energized by the contact between the first conductive sheet 9, which can prevent the wires from being disconnected during the disassembly and assembly of the temperature sensing detector body 4 when using wires for connection.

[0025] Reference Figure 3 As shown, in this implementation scheme: limiting grooves 7 are provided on both sides of the spring piece 6. When the user installs the temperature sensor body 4, in order to ensure that the second conductive sheet 19 fits tightly with the first conductive sheet 9, the spring piece 6 needs to be squeezed. In the process of flattening the spring piece 6, the spring piece 6 moves to both sides. In the process of the spring piece 6 moving to both sides, the limiting grooves 7 slide on the surface of the limiting round rod 5 to limit the movement of the spring piece 6, thereby preventing the spring piece 6 from tilting, resulting in a reduction in the contact area between the second conductive sheet 19 and the first conductive sheet 9, and causing poor contact.

[0026] Reference Figure 3 As shown, in this embodiment: the material of the spring piece 6 is a tough insulating material, and the fiberglass has the characteristics of light weight and high strength, good corrosion resistance, excellent insulation performance, good heat resistance, good toughness, etc. It can effectively prevent short circuits. At the same time, the elasticity will not be weakened by squeezing, so that the second conductive sheet 19 and the first conductive sheet 9 can always fit tightly.

[0027] Reference Figure 5 As shown, in this embodiment: positioning grooves 10 are provided on both sides of the base 1, and positioning blocks 11 are fixedly connected on both sides of the temperature sensor body 4. When the user installs the temperature sensor body 4 into the base 1, the positioning block 11 is aligned with the position of the positioning groove 10 and installed. The second conductive sheet 19 and the first conductive sheet 9 are positioned by the positioning block 11 and the positioning groove 10 to prevent the second conductive sheet 19 and the first conductive sheet 9 from being misaligned.

[0028] Reference Figure 6 As shown, in the present embodiment: both sides of the base 1 are provided with storage grooves 12, the interior of the storage grooves 12 is slidably connected with a limiting block 14, one side of the interior of the storage grooves 12 is provided with a through hole 13, one end of the limiting block 14 is fixedly connected with a connecting rod 15, the surface of the connecting rod 15 is slidably connected with the interior of the through hole 13, and both sides of the temperature sensor body 4 are provided with limiting grooves 20. The user aligns the positioning block 11 with the position of the positioning groove 10, installs the temperature sensor body 4 into the interior of the base 1, pushes the connecting rod 15 to drive the limiting block 14 to move inward, enters the interior of the limiting groove 20, limits the temperature sensor body 4, and facilitates the rapid installation of the temperature sensor body 4 into the interior of the base 1.

[0029] Reference Figure 6 As shown, in the present embodiment: one end of the limit block 14 is fixedly connected to two thrust springs 16, and the other end of the thrust spring 16 is fixedly connected to one side of the inside of the storage groove 12. The user aligns the positioning block 11 with the position of the positioning groove 10 and pushes the temperature sensor detector body 4 upward. The inclined surface of the limit block 14 is received in the compression recovery storage groove 12 at the top of the temperature sensor detector body 4, and at the same time, the thrust spring 16 accumulates force. When the limit groove 20 opened on the temperature sensor detector body 4 moves to the position of the limit block 14, the extrusion of the limit block 14 is released, and the thrust spring 16 pushes the limit block 14 into the inside of the limit groove 20.

[0030] Reference Figure 6As shown, in this embodiment: first slide grooves 17 are opened on both sides of the storage groove 12, and first sliders 18 are fixedly connected on both sides of the limit block 14. When the user pushes and pulls the connecting rod 15 to move the limit block 14, the first sliders 18 on both sides of the limit block 14 move inside the first slide grooves 17 to limit the movement of the limit block 14, thereby preventing the limit block 14 from tilting and causing jamming during the movement.

[0031] Working principle: The user passes the wire through the threading hole 3 to the inside of the base 1 and connects it to the terminal 8, passes the screw through the inside of the mounting hole 2 and fixes it to the wall, aligns the second conductive sheet 19 with the position of the first conductive sheet 9, and then installs the temperature sensing detector body 4 into the inside of the base 1. The elasticity of the spring sheet 6 makes the second conductive sheet 19 fit tightly with the first conductive sheet 9, so that the temperature sensing detector body 4 is energized. The contact between the second conductive sheet 19 and the first conductive sheet 9 can prevent the wire from being disconnected during the disassembly and assembly of the temperature sensing detector body 4 when using the wire connection. When installing the temperature sensing detector body 4, in order to ensure that the second conductive sheet 19 is tightly fitted with the first conductive sheet 9, and the spring sheet 6 needs to be squeezed. In the process of flattening the spring sheet 6, the spring sheet 6 moves to both sides. In the process of the spring sheet 6 moving to both sides, the limiting slide groove 7 slides on the surface of the limiting round rod 5 to limit the movement of the spring sheet 6 to prevent the spring sheet 6 from tilting, resulting in a reduction in the contact area between the second conductive sheet 19 and the first conductive sheet 9. The glass fiber reinforced plastic has the characteristics of light weight, high strength, good corrosion resistance, excellent insulation performance, good heat resistance, good toughness, etc., which can effectively prevent short circuits. At the same time, the elasticity will not be weakened by squeezing, so that the second conductive sheet 19 and the first conductive sheet 9 can always be tightly fitted, and the temperature sensing detection During the process of installing the detector body 4 into the base 1, align the positioning block 11 with the position of the positioning groove 10 and install it. The second conductive sheet 19 and the first conductive sheet 9 are positioned by the positioning block 11 and the positioning groove 10 to prevent the second conductive sheet 19 and the first conductive sheet 9 from being wrong. Align the positioning block 11 with the position of the positioning groove 10, install the temperature sensing detector body 4 into the base 1, push the connecting rod 15 to drive the limit block 14 to move inward, enter the limit groove 20, limit the temperature sensing detector body 4, and facilitate the rapid installation of the temperature sensing detector body 4 into the base 1. Align the positioning block 11 with the position of the positioning groove 10 , the temperature sensing detector body 4 is pushed upward, and the inclined surface of the limit block 14 is received in the compression recovery groove 12 at the top of the temperature sensing detector body 4, and the thrust spring 16 is charged at the same time. When the limit groove 20 opened on the temperature sensing detector body 4 moves to the position of the limit block 14, the extrusion of the limit block 14 is released, and the thrust spring 16 pushes the limit block 14 into the limit groove 20. In the process of pushing and pulling the connecting rod 15 to move the limit block 14, the first sliders 18 on both sides of the limit block 14 move inside the first slide groove 17 to limit the movement of the limit block 14 to prevent the limit block 14 from tilting and causing jamming during the movement.
