Description

Technical Field

[0001] The utility model belongs to the field of measuring instruments, and specifically relates to a laser rangefinder. Background Art

[0002] A laser rangefinder is an instrument that uses laser technology to measure distances and is widely used in fields such as construction, engineering, surveying and mapping, geographic information systems (GIS), and interior design.

[0003] For example, the laser rangefinder of model Hamai 500G lacks protection when the laser rangefinder is not in use. Even when the front and rear protective covers are installed, it is mostly a single plug-in structure, and it will fall off during bumps and transportation. At the same time, when using the laser rangefinder subsequently, it is also inconvenient to store the protective cover. Summary of the Utility Model

[0004] In view of the above defects, the utility model provides a laser rangefinder, which includes a rangefinder body. An OLED shoulder screen and an eyepiece are installed at the front end of the rangefinder body. A page-turning key and a function key are arranged on the top of the rangefinder body. A charging port, a battery compartment, an objective lens, and a laser are installed at the rear end of the rangefinder body. It also includes a front cover shell and a rear cover shell that are respectively adapted to the front and rear ends of the rangefinder body. The front cover shell includes a cover body I and a cover body II. One end where the cover body I and the cover body II are adjacent has an arc-shaped protrusion and an arc-shaped groove. Movable hooks are fixed at both ends where the cover body I and the cover body II are away from each other. The two movable hooks are respectively adapted to the hanging grooves opened on the left and right sides of the front end of the rangefinder body. Clamping plates are fixed on the upper and lower sides of the front cover shell close to the rangefinder body;

[0005] A baffle for covering the area where the page-turning key and the function key are located is fixed at the top end of the rear cover shell. A sponge pad is fixed on the side of the baffle close to the objective lens and the laser.

[0006] Further, the movable hook includes a C-shaped plate and a hook, and the hook is hinged to the C-shaped plate through a spring pin.

[0007] Further, the clamping plate is made of acrylic material and clamps the grooves preset on the upper and lower sides of the front end of the rangefinder body.

[0008] Further, slots are opened at the clamping plates located at the top. A buckle adapted to the slots is fixed at one end of the baffle away from the rear cover shell.

[0009] Further, a set of magnetic rings I and magnetic rings II with opposite magnetic poles are respectively inlaid at the ends of the front cover shell and the rear cover shell away from the rangefinder body, and the front cover shell can be placed inside the rear cover shell.

[0010] The utility model has the following beneficial effects compared with the prior art:

[0011] The lens and the operation panel that need to be protected are protected by the front cover and the rear cover. When fixing the front cover and the rear cover, not only can they be connected to both ends of the rangefinder body, but also they are connected to each other through a buckle and a slot to ensure the stability between the front cover and the rear cover.

[0012] When the rangefinder body is in use, the front cover can be placed inside the rear cover and magnetically adsorbed through the magnetic rings between them, which is convenient for storage. Description of the Drawings

Detailed Embodiments

[0016] To facilitate the understanding of the present utility model, the device of the present utility model will be described more comprehensively below with reference to the relevant drawings. Embodiments of the device are shown in the drawings. However, the device can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present utility model more thorough and comprehensive.

[0017] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "set" should be understood in a broad sense. For example, they can be fixedly connected and set, or detachably connected and set, or integrally connected and set. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0018] Embodiment

[0019] As Figure 1-2As shown in the figure, this embodiment provides a laser rangefinder, which includes a rangefinder body 1. An OLED shoulder screen 19 and an eyepiece 20 are installed at the front end of the rangefinder body 1. A page turning key 22 and a function key 21 are provided at the top of the rangefinder body 1. A charging port 15, a battery compartment 16, an objective lens 17 and a laser 18 are installed at the rear end of the rangefinder body 1. It also includes a front cover and a rear cover 11 that are respectively adapted to the front and rear ends of the rangefinder body 1. At one end of the front cover and the rear cover 11 away from the rangefinder body 1, a group of magnetic rings I 10 and magnetic rings II 14 with opposite magnetic poles are respectively inlaid. And the front cover can be placed inside the rear cover 11. Since the size of the rear end of the rangefinder body 1 is larger than that of the front end, that is, the area of the rear cover 11 should also be larger than that of the front cover. When storing, it can be stored by inserting method, and at the same time, it is adsorbed by magnetic force inside, having a certain fixing effect;

[0020] The front cover includes a cover body I 31 and a cover body II 32. One end where the cover body I 31 and the cover body II 32 are adjacent is respectively an arc-shaped protrusion 6 and an arc-shaped groove 7. After the arc-shaped protrusion 6 and the arc-shaped groove 7 are combined, they are located at the eyepiece 20. At one end of the cover body I 31 and the cover body II 32 away from each other, a movable hook 4 is fixed. The movable hook 4 includes a C-shaped plate and a hook. The hook is hinged to the C-shaped plate through a spring pin. The two movable hooks 4 are respectively adapted to the hanging grooves 5 opened on the left and right sides of the front end of the rangefinder body 1. There are hanging grooves 5 at both ends of the traditional rangefinder body 1, which are generally used for threading a hanging rope. Through the movable connection with the movable hook 4, the connection between the cover body I 31 and the cover body II 32 and the rangefinder body 1 can be ensured;

[0021] At the upper and lower sides of one end of the cover body I 31 and the cover body II 32 close to the rangefinder body 1, clamping plates 8 are fixed. The clamping plates 8 are made of acrylic material, which has a certain hardness and also has a certain toughness, and clamp the preset grooves on the upper and lower sides of the front end of the rangefinder body 1. That is, the clamping plates 8 should be slightly inclined. When clamping with the grooves, the clamping effect is realized through its own deformation. Specifically, clamping slots 9 are opened at the clamping plates 8 at the top. One end of the baffle 12 away from the rear cover 11 is fixed with a buckle 13 adapted to the clamping slots 9. Its function is that by inserting the buckle 13 into the inside of the clamping slots 9, the connection between the front cover and the rear cover 11 is achieved, increasing the fixing effect of the two on the rangefinder body 1 and preventing the phenomenon of falling off during subsequent movement;

[0022] A baffle 12 for covering the area where the page turning key 22 and the function key 21 are located is fixed at the top end of the rear cover 11. A sponge pad is also fixed on one side of the baffle 12 close to the objective lens 17 and the laser 18.

[0023] It should be noted that the shapes of the front cover and the rear cover 11 should respectively correspond to the outer edges of the front and rear ends of the rangefinder body 1 to ensure the adaptability during subsequent installation.

[0024] It should be noted that the structure described in the present utility model can be implemented in various different forms, and is not limited to the embodiments. Any equivalent transformation made by those of ordinary skill in the art using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, such as the loading and unloading of other articles, is included in the protection scope of the present utility model.
