[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0034] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0035] Please see Figures 1 to 3 The present invention provides a personnel safety laser rangefinder module, comprising: a rangefinder body 1, wherein a plurality of buttons 5 and a laser lens 2 are installed inside the rangefinder body 1, a limiting structure 3 is provided on the side of the rangefinder body 1 away from the buttons 5, and an auxiliary structure 4 is provided on the inner wall of the fixing plate 304.

[0036] In the embodiments of this utility model, please refer to Figures 4 to 6 The limiting structure 3 includes two fixing blocks 301 and a fixing plate 304. The two fixing blocks 301 are fixedly connected to the rangefinder body 1, and the fixing plate 304 is fixedly connected to the rangefinder body 1. A rotating rod 302 is rotatably connected to one side of the two fixing blocks 301 that is close to each other. A limiting band 303 is fixedly connected to the arc surface of the rotating rod 302. A limiting groove 307 is opened in the inner wall of the fixing plate 304. An insert rod 310 is slidably connected to the inner wall of the fixing plate 304. A moving plate 305 is slidably connected to the inner wall of the limiting groove 307. A positioning hole 306 is opened in the inner wall of the moving plate 305. A spring 309 is sleeved on the arc surface of the insert rod 310. The two ends of the spring 309 are fixedly connected to the insert rod 310 and the fixing plate 304 respectively. The moving plate 305 is fixedly connected to the limiting band 303, and the positioning hole 306 is slidably connected to the insert rod 310. When a person uses the rangefinder body 1 for a long time, their hands will sweat. The sweat will reduce the friction between the person's hand and the rangefinder body 1, which may cause the rangefinder to slip from the person's hand during the distance measurement process. This problem can be solved by the limiting structure 3. By setting the limiting structure 3, when the person holds the rangefinder body 1, the person moves the moving plate 305 so that the limiting band 303 fits against the back of the person's hand, and then the moving plate 305 slides into the inner wall of the limiting groove 307 until the moving plate 305 is completely slid into the inner wall of the limiting groove 307 and the insertion rod 310 slides into the inner wall of the positioning hole 306. This can prevent the rangefinder body 1 from slipping from the person's hand during the distance measurement process. The end of the insertion rod 310 away from the limiting groove 307 is fixedly connected to a pull ring 311, and the cross-section of the pull ring 311 is circular. The pull ring 311 facilitates the movement of the insertion rod 310, improving operational convenience. Three positioning blocks 308 are fixedly connected to one side of the fixing plate 304, evenly distributed at the opening of the limiting groove 307. The positioning blocks 308 limit the movement of the moving plate 305, allowing it to slide easily into the inner wall of the limiting groove 307. An anti-slip sleeve 312 is fixedly connected to the arc surface of the pull ring 311. The anti-slip sleeve 312 has a hollow circular cross-section. The anti-slip sleeve 312 increases the friction between the user's hand and the pull ring 311, preventing slippage during movement.

[0037] In the embodiments of this utility model, please refer to Figure 7 and Figure 8The auxiliary structure 4 includes a connecting groove 41 and two connecting grooves 45. The connecting groove 41 is formed on the fixed plate 304, and the two connecting grooves 45 are also formed on the fixed plate 304. The two connecting grooves 45 are interconnected with the connecting groove 41. A connecting block 46 is slidably connected to the inner wall of the connecting groove 45. A top plate 44 is fixedly connected to the side of the two connecting blocks 46 that is close to each other. A compression spring 43 is provided between the side of the top plate 44 away from the limiting groove 307 and the connecting groove 41. The two ends of the compression spring 43 are fixedly connected to the top plate 44 and the connecting groove 41 respectively. The connecting groove 41 is interconnected with the limiting groove 307. When personnel need to slide the movable plate 305 out of the inner wall of the limiting groove 307, the auxiliary structure 4, after the personnel slide the insertion rod 310 out of the inner wall of the positioning hole 306, causes the compression spring 43 to rebound, driving the top plate 44 to move away from the connecting groove 41. The top plate 44 then drives the movable plate 305 to move away from the limiting groove 307 until part of the movable plate 305 slides out of the inner wall of the limiting groove 307, thus facilitating the personnel to slide the movable plate 305 out of the inner wall of the limiting groove 307 and improving the ease of operation. A telescopic rod 42 is fixedly connected to the inner wall of the connecting groove 41, and the output end of the telescopic rod 42 is fixedly connected to the top plate 44. The telescopic rod 42 can limit the top plate 44, preventing misalignment during the sliding process of the top plate 44 on the inner wall of the connecting groove 41. A protective pad 47 is fixedly connected to the side of the top plate 44 near the limiting groove 307, and the protective pad 47 is slidably connected to the connecting groove 41. The protective pad 47 can protect the top plate 44 and the movable plate 305, and can prevent the side of the top plate 44 near the limiting groove 307 from directly contacting the movable plate 305.

[0038] The working principle of the personnel safety laser rangefinder module provided by this utility model is as follows: When a person needs to use the rangefinder body 1 for distance measurement, the person can first hold the rangefinder body 1, and then move the moving plate 305. The moving plate 305 drives one end of the limiting band 303 to move closer to the fixed plate 304, so that the limiting band 303 is in contact with the back of the person's hand until the moving plate 305 corresponds to the groove of the limiting groove 307. Then the person moves the moving plate 305 closer to the limiting groove 307. The positioning block 308 on one side of the fixed plate 304 can limit the moving plate 305, which makes it easy for the person to slide the moving plate 305 into the inner wall of the limiting groove 307 until the moving plate 305 slides into the inner wall of the limiting groove 307. As the movable plate 305 slides into the inner wall of the limiting groove 307, it also drives the insertion rod 310 to move away from the limiting groove 307. The insertion rod 310 drives the pull ring 311 to move away from the limiting groove 307. The pull ring 311 facilitates the movement of the insertion rod 310, improving the ease of operation. Then, the insertion rod 310 also drives the spring 309 to stretch, and the pull ring 311 drives the anti-slip sleeve 312 to move away from the limiting groove 307. The anti-slip sleeve 312 increases the friction between the user's hand and the pull ring 311, preventing slippage during the movement of the pull ring 311. This continues until the positioning hole 306 aligns with the insertion rod 310. At this point, the spring 309 rebounds, causing the insertion rod 310 to slide into the inner wall of the positioning hole 306.

[0039] Additionally, when the person slides the insertion rod 310 out of the inner wall of the positioning hole 306, the compression spring 43 rebounds, causing the top plate 44 to move away from the connecting groove 41. The top plate 44 then moves the output ends of the two connecting blocks 46 and the telescopic rod 42 away from the connecting groove 41. The telescopic rod 42 can limit the top plate 44, preventing it from shifting during sliding on the inner wall of the connecting groove 41. The top plate 44 also moves the protective pad 47 away from the connecting groove 41. The protective pad 47 protects the top plate 44 and the moving plate 305, preventing the side of the top plate 44 near the limiting groove 307 from directly contacting the moving plate 305. The protective pad 47 then moves the moving plate 305 away from the connecting groove 41 until part of the moving plate 305 slides out of the inner wall of the limiting groove 307. At this point, the positioning hole 306 and the insertion rod 310 are just misaligned.

[0040] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0041] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
