[0019] The following is combined with Figure 1-5 This application is described in further detail.
[0020] The embodiment of the present application discloses a self-cleaning handheld laser rangefinder, comprising a rangefinder body 1 and an optical lens 3 arranged on the rangefinder body 1, and a sliding cover 2 is arranged on the rangefinder body 1, the sliding cover 2 moves on the surface of the rangefinder body 1, and can cover the optical lens 3, and a cleaning sheet 16 is arranged on the sliding cover 2, when the sliding cover 2 moves on the rangefinder body 1, the cleaning sheet 16 can clean the optical lens 3, and a winding mechanism is also arranged on the sliding cover 2 for winding up the contaminated cleaning sheet 16.
[0021] Furthermore, the winding mechanism includes rollers 14 rotatably mounted on both sides of the sliding cover 2, and a motor 13 is fixedly mounted on the surface of the sliding cover 2, the output shaft of the motor 13 is fixedly connected to one of the rollers 14, and both sides of the cleaning sheet 16 are mounted on the two rollers 14 through a connecting mechanism.
[0022] Furthermore, the connection mechanism includes a cylinder 15 fixedly mounted on both sides of the cleaning sheet 16, and a roller 14 is inserted into the cylinder 15, a bump is arranged on the surface of the roller 14, and a groove matching the bump is arranged on the inner surface of the cylinder 15.
[0023] In actual use, the cleaning sheet 16 is a rollable flexible cotton cloth, and the two cylinders 15 are used to roll up the clean cleaning sheet 16 and the contaminated cleaning sheet 16 respectively. When installing, it is only necessary to align the groove on the cylinder 15 with the protrusion on the roller 14, and insert the roller 14 into the cylinder 15. When the rolled cleaning sheet 16 is used up, the cleaning sheet 16 can be replaced.
[0024] In this embodiment, when the rangefinder body 1 is used, the slide cover 2 needs to be removed from the optical lens 3 to expose the optical lens 3, and when the slide cover 2 moves, the cleaning sheet 16 on the slide cover 2 can wipe the optical lens 3 to remove dust on the optical lens 3, so that the rangefinder body 1 can accurately measure.
[0025] Specifically, after the cleaning sheet 16 has been used for a period of time, its dirt removal performance decreases. In this embodiment, by driving the motor 13 to rotate, the roller 14 can be driven to rotate, so that the roller 14 can roll up the contaminated cleaning sheet 16, and the clean cleaning sheet 16 on the other cylinder 15 can be spread out, so as to continue cleaning the optical lens 3.
[0026] Furthermore, an inner groove 6 is formed on the inner surface of the sliding cover 2, a pressure block 7 is arranged inside the inner groove 6, and a guide rod 9 is fixedly connected inside the inner groove 6. The guide rod 9 is inserted into the pressure block 7, and a compression spring 8 is sleeved on the surface of the guide rod 9. The pressure block 7 is located between the two rollers 14, and the pressure block 7 is against the surface of the cleaning sheet 16.
[0027] In this embodiment, by providing a compression spring 8 and a compression block 7 , the compression spring 8 presses against the compression block 7 , and the compression block 7 thereby presses the cleaning sheet 16 tightly, so that the cleaning sheet 16 is closely attached to the optical lens 3 , ensuring that the cleaning sheet 16 can wipe the optical lens 3 .
[0028] Furthermore, a rotating plate 4 is rotatably connected to one side of the sliding cover 2 via a hinge, and first magnetic strips 5 are fixedly connected to both the rotating plate 4 and the sliding cover 2, and the first magnetic strips 5 attract each other.
[0029] In this embodiment, when the cleaning sheet 16 needs to be replaced, the rotating plate 4 can be opened to take the cleaning sheet 16 out of the sliding cover 2. By providing the first magnetic strip 5, the rotating plate 4 can be adsorbed on the sliding cover 2 when the rotating plate 4 is closed.
[0030] Furthermore, a slider 11 is fixedly connected to the surface of the sliding cover 2, and a slide groove 10 adapted to the slider 11 is formed on the rangefinder body 1. The inner wall of the slide groove 10 and the surface of the slider 11 are fixedly connected to a second magnetic strip 12, and the second magnetic strips 12 attract each other.
[0031] In this embodiment, by providing a slide groove 10 and a slider 11, the slide cover 2 can move on the surface of the rangefinder body 1, and by providing a second magnetic strip 12, the slide cover 2 can be adsorbed on one side of the slide groove 10 to ensure that the slide cover 2 can stabilize the surface of the optical lens 3.
