Embodiment 1

[0037] Such as Figure 1-8As shown, the present invention provides a laser rangefinder provided with a protective mechanism, including a protective frame 1 and a laser rangefinder body 12, the top of the protective frame 1 is detachably connected with a protective cover 11, and the protective frame 1 A protective mechanism 2 is provided in the inner cavity of the protective frame body 1. A cleaning mechanism 3 is provided on the left side of the protective frame body 1. A convenient fixing mechanism 4 is provided at the bottom of the protective frame body 1. The protective mechanism 2 includes a screw rod 21 and a fixed rod 22. The screw rod 21 is threaded Connected to the bottom of the protective frame 1, the fixed rod 22 is fixedly welded in the inner cavity of the protective frame 1, the outer wall of the fixed rod 22 is slidably connected with a sliding seat 23, and the top of the screw rod 21 is rotationally connected with the bottom of the sliding seat 23, The cleaning m...

Embodiment 2

[0039] Such as Figure 1-8 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: preferably, the top of the sliding seat 23 is rotatably connected with a rotating seat 24, and the top of the rotating seat 24 is threaded with an angle fixing bolt, and the laser range finder The main body 12 is fixedly installed on the top of the rotating seat 24, which can impel the screw rod 21 to rotate downward at the bottom of the protective frame 1, and then drive the sliding seat 23 to slide downward on the outer wall of the fixed rod 22 and make the rotating seat 24 move down. The downward movement of the rotating seat 24 makes the laser rangefinder body 12 move into the inner cavity of the protective frame 1, and finally the protective frame 1 is closed, that is, the laser rangefinder body 12 is safely protected to avoid laser The outer wall of the rangefinder body 12 collides or rubs against external objects, prolonging the service life of the las...

Embodiment 3

[0041] Such as Figure 1-8 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: preferably, the fixed ring 32 is fixedly sleeved on the outer wall of the rotating base 24, and the outer wall of the fixed ring 32 is fixedly equipped with a folding rod 321, which is folded One end of the rod 321 away from the fixed ring 32 is fixedly mounted with a drive cover 322, and the cleaning drive cylinder 31 is fixedly mounted on the left side of the protective frame body 1, and a metal mesh plate 311 is detachably connected to the inner cavity of the cleaning drive cylinder 31, and the cleaning drive cylinder 31 A fine filter plate 312 is fixedly installed in the inner cavity of the fine filter plate 312, and a guide cone 313 is movably inserted on the left side of the fine filter plate 312, and a fine filter mechanism 314 is arranged on the right side of the guide cone 313, and the fine filter mechanism 314 includes a connecting ring 3141, which i...

Abstract

The invention discloses a laser range finder with a protection mechanism, and relates to the technical field of range finders, the laser range finder comprises a protection frame body and a laser range finder body, the top of the protection frame body is detachably connected with a protection cover, the protection mechanism is arranged in an inner cavity of the protection frame body, and the left side of the protection frame body is provided with a cleaning mechanism. And a convenient fixing mechanism is arranged at the bottom of the protection frame body, and the protection mechanism comprises a screw rod and a fixing rod. By correspondingly rotating the screw rod, the screw rod can be promoted to rotate downwards at the bottom of the protective frame body, then the sliding seat is driven to slide downwards on the outer wall of the fixed rod, the rotating seat is made to move downwards, the laser range finder body is made to move into the inner cavity of the protective frame body through the downward movement of the rotating seat, and finally the protective frame body is closed. Therefore, safety protection treatment on the laser range finder body is realized, and the problem of collision or friction between the outer wall of the laser range finder body and an external object is avoided.

Description

technical field [0001] The invention relates to a laser rangefinder, relates to the technical field of rangefinder, in particular to a laser rangefinder provided with a protection mechanism. Background technique [0002] The laser range finder is an instrument that uses laser to accurately measure the distance of the target. The laser range finder emits a very thin laser beam to the target when it is working, and the photoelectric element receives the laser beam reflected by the target. The timer measures the laser beam from The time from transmission to reception calculates the distance from the observer to the target. There are following problems at prior art: [0003] 1. The existing laser range finder does not have the function of self-safety protection. During the turnover process of the laser range finder, the outer wall of the laser range finder will inevitably bump or rub against external objects, thus affecting the laser The service life of the rangefinder needs t...
