Description

Technical Field

[0001] The utility model relates to the field of laser rangefinders, in particular to a handheld laser rangefinder. Background Art

[0002] The working principle of the laser rangefinder is to determine the distance to the target by emitting a laser beam and receiving the reflected laser beam, and calculating the time it takes for the laser to travel back and forth. This measurement method is very accurate and easy to operate, and is widely used in many fields such as construction, land surveying and mapping, and logistics handling.

[0003] After searching, the application number is "202223117339.9", which provides a handheld laser rangefinder. After measuring the distance of multiple objects, when the button needs to be protected, press the anti-skid pad and use the anti-skid pad to push the protective cover, wherein the anti-skid pad has the effect of increasing the friction between the hand and the protective cover. Since the cross-section of the arc block is arc-shaped, the protective cover will drive the slide rail to slide along the surface of the fixed bar when the thrust is applied. At this time, the first spring will slide and be squeezed along the arc surface of the guide rod, wherein the guide rod has the effect of limiting the direction of the elastic force of the first spring, and the insert block will slide along the inner wall of the storage groove of the fixed bar. When the arc block is separated from the inner wall of the card hole, the second spring will give the protective cover a pulling force to drive the slide rail to slide along the inner wall of the fixed bar, wherein the second spring has the effect of quickly driving the protective cover to move to the appropriate position. When the protective cover completely covers the button, the first spring will give the insert block an outward elastic force, thereby driving the arc block to insert into the card hole to fix the protective cover position. By setting the protective structure, the effect of protecting the button is achieved, thereby avoiding accidental touching of the button.

[0004] The above-mentioned sliding protective cover protects the button of the laser rangefinder to prevent external force from hitting the button. However, this structure requires the protective cover to be slid out when the button is used. The slid-out protective cover takes up a large space, making it inconvenient for the staff to operate the laser rangefinder while holding it, and the operation is troublesome. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art that a protective cover is used to protect the buttons, which easily occupies the usable space and is troublesome to operate, one of the purposes of the utility model is to provide a handheld laser rangefinder.

[0009] According to the handheld laser rangefinder, the limit frame is made of metal material.

[0010] According to the handheld laser rangefinder, a magnetic plate is fixedly connected to the right side of the fixing plate, so as to facilitate the positioning of the limiting frame.

[0011] According to the handheld laser rangefinder, the connecting plate is slidably connected to the storage slot.

[0012] According to the handheld laser rangefinder, the limit frame is arranged in a U-shaped structure.

[0013] Beneficial effects:

[0014] By providing a fixed plate, a storage slot, a lifting slot, a lifting block, a connecting plate, a connecting block, a protective plate and a limit frame, the protective plates on the front and rear sides can protect the keys, and by rotating the protective plates, the protective plates can be conveniently moved to the storage slot, thereby reducing the space occupied by the protective plates when the keys are in use, making it easier to use.
