[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1 , Figure 2 As shown, the embodiment of the utility model discloses a handheld infrared thermometer, including a thermometer body 1, an infrared probe 11 is provided at the front end thereof, and buttons 12 (on / off button and mode switching button, etc.) and a display screen 13 are provided at the end thereof. A base 14 extends from the lower part of the thermometer body 1, and a temperature measurement button 15 is provided at one end of the base 14. The thermometer body 1 and the infrared probe 11, button 12, display screen 13, base 14 and temperature measurement button 15 thereon are all prior art. The temperature measurement button 15 is a trigger type. The thermometer body 1 also includes: a temperature measurement distance adjustment component 2, a limit block 3 and a pull-out starting component 4: the temperature measurement distance adjustment component 2 One end is installed under the base 14, and is used to control the thermometer body 1 to move forward and backward along the direction of its infrared probe, thereby changing the distance between the thermometer body and the user; a limit block 3 is fixedly extended downward from the base 14; the pull-out starting component 4 is located below the temperature measurement distance adjustment component 2, and the other end passes through the limit block 3 and can contact the temperature measurement button 15, that is, the trigger-type temperature measurement button, in the working state, and keep the temperature measurement button working continuously when continuously pulled. In the non-working state, there is a certain distance from the temperature measurement button 15, and the pull-out starting component 4 is slidably connected to the limit block 3.

[0025] According to the needs of use, the distance of the temperature measurement distance adjustment component 2 is adjusted to drive the thermometer body 1 to move forward and backward, and the pull-out activation component 4 is used to control the temperature measurement button 15 to start the temperature measurement, thereby preventing burns caused by high temperature when measuring high-temperature objects. When the pull-out activation component 4 remains stationary at a certain distance, the temperature measurement distance adjustment component 2 moves forward to ensure that the pull-out activation component 4 continuously presses the temperature measurement button 15.

[0026] like Figure 1 、 Figure 3 and Figure 4 As shown, the temperature measurement distance adjustment assembly 2 includes a support plate 21 fixedly connected to the base 14. Two sets of symmetrical push rods 22 are hinged on both sides of the bottom of the support plate 21. The other side of the push rod 22 is provided with a slider 23 rotatably connected thereto. Specifically, the bottom of the push rod 22 is rotatably connected to the top of the slider 23, and the slider 23 is slidably connected to the adjustment mechanism 24 below. The pull-out starting assembly 4 is installed below the adjustment mechanism 24; the bottom of the slider 23 is provided with a threaded adapter plate, and the adjustment mechanism 24 includes a double-threaded screw 241 rotatably connected to the adapter plates of the two sets of sliders 23. The two threaded segments of the double-threaded screw have opposite rotation directions. As an optional embodiment, the middle section of the two threaded segments can also be provided with a limited end to ensure that the shortest distance between the two sliders is a preset limit distance. A double-threaded screw 241 is mounted within a rectangular trough 242, with a handwheel 243 fixedly connected to one side of the trough 242. The slider 23 is slidably connected to the trough 242. A grip 244 is provided on the user-facing side of the trough 242 for convenient handheld temperature measurement. The user-facing end of the pull-out activation assembly 4 is connected to the bottom of the trough 242. A threaded adapter plate ensures that the thermometer body can move along a predetermined path, allowing the pull-out activation assembly 4 to precisely align with the temperature measurement button 15 on the thermometer body.

[0027] Holding the handle 244, aim the infrared probe 11 at the temperature measuring device, and using the other hand to turn the handwheel 243, the handwheel 243 drives the double-threaded screw 241 to rotate in the groove 242, thereby adjusting the two sets of sliders 23 to slide on the groove 242, and synchronously changing the distance between the two sets of push rods 22, so that the support plate 21 at the front end moves forward, and drives the thermometer body 1 to move forward, changing the temperature measurement distance, and avoiding burns at close range.

[0028] like Figure 3 and Figure 5 The pull-out starting assembly 4 includes a U-shaped pull-out rod 41 slidably connected to the limit block 3, and the other end of the pull-out rod 41 is slidably connected to a raised block 42 fixed to the bottom of the groove body 242. An inverted U-shaped starting rod 43 extends vertically from the side of the pull-out rod 41 close to the limit block 3. In the working state, the starting rod 43 can contact the temperature measurement button 15, and the thermometer body 1 is started by pulling the pull-out rod 41 to contact the temperature measurement button 15;

[0029] After the distance is adjusted, the pull rod 41 is pulled along the side away from the thermometer body 1. The pull rod 41 slides on the protrusion 42 and slides on the limit block 3. The linkage start rod 43 moves toward the user, thereby pressing the temperature measurement button 15 of the thermometer body 1 to start the temperature measurement.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
