[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] Example: A portable handheld infrared thermometer, such as Figure 1As shown, it includes a detection body 1 and an energy storage body 2, which are movably connected. A telescopic connection component is provided between the detection body 1 and the energy storage body 2. The telescopic connection component enables flexible disassembly and assembly during the use of the thermometer, facilitating quick switching between different equipment states for easy use and convenient carrying.

[0019] like Figure 1 and Figure 2 As shown, the telescopic connection assembly includes a pair of elastic telescopic connecting rods 3. Each elastic telescopic connecting rod 3 includes a connecting rod 4 and a connecting sleeve 5 that are inserted into each other. The connecting sleeve 5 is provided with a socket groove 6 for the connecting rod 4 to be inserted into. A reset spring 7 is provided in the socket groove 6. The ends of the connecting rod 4 and the connecting sleeve 5 that are away from each other are rotatably connected to the sides of the detection body 1 and the energy storage body 2, respectively. By relying on the elastic telescopic tension between the connecting rod 4 and the connecting sleeve 5, the flexible assembly and disassembly between the detection body 1 and the energy storage body 2 can be realized simultaneously. The reset spring 7 realizes the elastic telescopic process.

[0020] The detector body 1 is equipped with a screen display block 8 and a temperature probe 9. The infrared temperature probe 9 senses and measures the temperature, and the screen display block 8 provides real-time feedback of the temperature parameters. A detection slot 10 is provided at the end of the detector body 1 away from the energy storage body 2. An adjustment shaft 11 is provided between the temperature probe 9 and the wall of the detection slot 10, allowing the user to manually adjust the detection direction of the temperature probe 9.

[0021] like Figure 1 and Figure 3As shown, the end of the probe body 1 furthest from the temperature probe 9 is provided with a insertion cavity 12. The cavity wall of the insertion cavity 12 is provided with conductive electrode plates 13. At the end of the energy storage body 2, there is an insertion block 14 that engages with the insertion cavity 12. When the instrument needs to be used, the operator rotates the probe body 1 and the energy storage body 2 to a straight position, and simultaneously pulls the energy storage body 2 outward, causing the connecting rod 4 and connecting sleeve 5 to extend. After the insertion block 14 aligns with the insertion cavity 12, the pulling force is released. Under the elastic recovery potential energy of the reset spring 7, the connecting rod 4 and connecting sleeve 5 are quickly retracted, completing the rapid assembly of the probe body 1 and the energy storage body 2. The insertion block 14... The side wall is provided with a through electrode plate 15 that cooperates with the conductive electrode plate 13. As the plug block 14 and the plug cavity 12 are engaged, the conductive electrode plate 13 and the through electrode plate 15 are connected, thus providing power to the detection body 1 for part of the detection work. In this state, the reset spring 7 always maintains elastic tension, further improving the reliability of the plug connection between the detection body 1 and the energy storage body 2. When the instrument needs to be disassembled for easy carrying, the user pulls out the energy storage body 2, causing the connecting rod 4 and the connecting sleeve 5 to stretch. After the plug block 14 and the plug cavity 12 are separated, the energy storage body 2 and the detection body 1 can be flipped and stacked for efficient storage. The sides of the detection body 1 and the energy storage body 2 are also provided with elastic anti-slip protective pads 21 to ensure the tightness of the fit between the detection body 1 and the energy storage body 2 after stacking, reducing the instability of relative slippage.

[0022] A sliding cover block 16 is movably connected to the end of the energy storage body 2 away from the detector body 1. The sliding cover block 16 is provided with a sliding slot 17. The end of the energy storage body 2 is provided with a sliding plug 18 for the sliding slot 17 to be inserted. When the thermometer needs to be placed vertically, the user can manually slide out the sliding cover block 16 to increase the contact area of ​​the bottom of the thermometer and improve the stability of the instrument. A fixing pad 22 is also provided on one side of the sliding plug 18 at the end of the energy storage body 2. The fixing pad 22 is level with the sliding cover block 16 to improve the reliability and stability of the vertical position.

[0023] When the instrument is folded up in a non-working state, as the energy storage body 2 flips to the side of the detection body 1, the sliding cover 16 can also protect the temperature probe 9, reducing friction and damage during carrying. Since the energy storage body 2 is flipped up and folded up, the sliding cover 16 and the detection slot 10 are on the same side. The slot of the detection slot 10 is provided with a protective plug 19 that engages with the sliding slot 17. The user can slide the sliding cover 16 to one side to engage with the protective plug 19, thereby protecting the temperature probe 9. The sliding cover 16 and the protective plug 19 are engaged, which also achieves the fastening of the temperature measuring body and the energy storage body 2 after disassembly.

[0024] To protect the electrode plate 15 of the connector block 14, a movable protective sleeve 20 is provided at the end of the energy storage body 2. The movable protective sleeve 20 is movably sleeved with the connector block 14. In the disassembled state, the user slides the movable protective sleeve 20 onto the end of the connector block 14 to cover the electrode plate 15. The surface of the movable protective sleeve 20 is provided with anti-slip grooves 23, which improves the stability and convenience of applying force during manual operation.

[0025] Due to the performance requirements of infrared temperature measurement equipment, after long-term use, unstable power supply voltage may occur due to battery cell aging, which in turn affects the working precision of the infrared instrument. The energy storage body 2 is equipped with a detachable battery cell block, which facilitates the equipment maintenance and disassembly needs during use.

[0026] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
