Description

Technical Field

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

[0002] Laser rangefinder is an instrument that uses a certain parameter of modulated laser to measure the distance to the target. Laser rangefinder is light, small, easy to operate, fast and accurate, and its error is only one-fifth to several hundredths of other optical rangefinders.

[0003] When using a laser rangefinder at a construction site, it is found that the laser rangefinder is usually in contact with the ground. Then, when adjusting the position of the laser rangefinder for distance measurement, it is necessary to measure the distance outdoors in the sunlight. The sunlight is easily reflected by the rangefinder, making it difficult for people to view the measured data.

[0004] Therefore, we made improvements to this and proposed a laser rangefinder for engineering inspection. Utility Model Content

[0005] The utility model aims to solve the problem that it is necessary to measure distance in outdoor sunlight, but the sunlight is easy to reflect the light of the distance meter, which makes it difficult for people to check the measured data.

[0039] Example 1

[0040] Please refer to Figure 1-8 A laser rangefinder for engineering inspection includes a rangefinder 6, a display screen 61 is provided on the upper part of the outer surface of the rangefinder 6, a button 62 is installed on the lower part of the outer surface of the rangefinder 6, an outer protective shell 1 is wrapped around the outer side of the rangefinder 6, a rotating shaft 7 is connected to the top of the outer protective shell 1, and disassembly parts are connected to the outer surfaces of both ends of the rotating shaft 7, an upper baffle 2 is connected to the outer surface of the rotating shaft 7, a connecting shaft 3 is connected to the bottom of the upper baffle 2, a lower slide 4 is provided on the bottom side of the connecting shaft 3, sliding parts are provided on the inner walls on both sides of the outer protective shell 1, and a clamping part is provided on the bottom of the rear surface of the lower slide 4. The sliding part includes a slider 41 installed on both sides of the bottom end of the rear surface of the lower slide 4, and a slide groove 13 is provided on the surface of the two inner side walls of the outer protective shell 1, and the opening width of the slide groove 13 gradually increases from bottom to top along the inner wall of the outer protective shell 1. The clamping part includes a hook 42, and a clamping groove 21 is provided on the upper side of the rear surface of the upper baffle 2.

[0041] During the implementation process, when the rangefinder 6 is used outdoors, in order to reduce the influence of external sunlight on the observation data, after being placed horizontally, the lower slide plate 4 is pulled upward, and then the slider 41 slides inside the slide groove 13, and the upper baffle 2 and the lower slide plate 4 are folded through the connection of the connecting shaft 3, and the hook 42 is inserted into the card groove 21 for clamping and fixing. The upper baffle 2 rotates under the action of the rotating shaft 7, and rotates inside the limiting groove 14 through the spring pins 71 at both ends of the rotating shaft 7. There is a certain friction between the spring pin 71 and the limiting groove 14 to support the upper baffle 2 and the lower slide plate 4 for adjusting the angle to block the sunlight, and the slider 41 slides in the slide groove 13. Since the opening width of the slide groove 13 gradually increases from bottom to top, it is convenient to remove the upper baffle 2, the connecting shaft 3, and the lower slide plate 4 from the inside of the outer protective shell 1 through the disassembly parts in the later stage for maintenance and replacement.

[0042] Example 2

[0043] The disassembly part includes spring pins 71 installed at both ends of the rotating shaft 7. Slide blocks 41 are opened inside the two upper ends of the outer protective shell 1. The inside of the slide block 41 is slidably connected with the pressing cylinder 5. The spring pins 71 are slidably arranged inside the slide block 41.

[0044] During the implementation process, the spring pins 71 at both ends of the rotating shaft 7 extend into the limiting groove 14 to facilitate the rotation of the rotating shaft 7. The pressing cylinder 5 that is slidably connected to the outer side of the outer protective shell 1 and opposite to the spring pin 71 inside the limiting groove 14 can press the pressing cylinder 5 inward, thereby squeezing the spring pin 71 to detach the spring pin 71 from the inside of the limiting groove 14 to remove the upper baffle 2 and the lower slide plate 4.

[0045] Example 3

[0046] The rear surface of the outer protective shell 1 is provided with rubber pads 12 in a linear array, and a supporting corrugated plate 11 is installed between the rubber pads 12 and the rear surface of the rangefinder 6, and the supporting corrugated plate 11 is wavy.

[0047] During the implementation process, the supporting corrugated plate 11 disposed inside the outer protective shell 1 supports the space between the outer protective shell 1 and the rangefinder 6 at the rear, and the setting of the rubber pad 12 increases a certain buffering force during collision, thereby protecting the rangefinder 6.

[0048] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
