[0014] An optical distance meter for urban construction planning, such as Figs. 1-3 As shown, the rangefinder body 1 includes a shielding portion that can be removed and installed on the top of the rangefinder body 1. A through hole is defined in the middle of the shielding portion, and a blocking member can be removed and installed in the through hole. A protective member can be removed and installed in the front of the shielding portion. The rangefinder body 1 is a handheld rangefinder, such as the Shendawei SW-TA50 laser rangefinder, the Deli DL-50 laser rangefinder, the Delixi Electric DT10 laser rangefinder, and the Bosch GLM 4000 laser rangefinder. When used outdoors, the blocking member is removed, and the lens of the rangefinder body 1 measures the outside world through the through hole. The shielding portion blocks the sun to prevent direct sunlight from hitting the lens and damaging the optical components. When not in use, the blocking member is installed in the through hole. The blocking member and the blocking member protect the lens of the rangefinder body 1 and prevent dust from adhering to the lens, thereby preventing the distance measurement effect. At the same time, the protective member is installed on the shielding portion. The protective member protects the display screen and buttons on the front of the rangefinder body 1, preventing a large amount of dust from adhering to the display screen and buttons.

[0015] Specifically, the shielding portion described in this embodiment includes: The shielding plate 2 is located above the rangefinder body 1, a placement hole 4 is provided at one corner of the shielding plate 2, and a through hole is provided in the middle of the top surface of the shielding plate 2; Three insertion rods 3, the three insertion rods 3 are respectively fixedly mounted on the remaining bottom triangles of the shielding plate 2; The screw rod 5 passes through the placement hole 4 and is movably installed in the placement hole 4 through a bearing; Three jacks, the three jacks are provided on the top surface of the rangefinder body 1, and the insertion rod 3 can be inserted into the corresponding jacks; The screw hole is provided on the top surface of the rangefinder body 1 , and the screw rod 5 can be inserted into the screw hole and matched with the screw thread.
