Description

Technical Field

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

[0002] With the rapid development of real estate and other construction industries, measuring tools such as tape measures, which are somewhat dangerous, are gradually being eliminated. Instead, distance measuring tools such as rangefinders that use the reflection and interference characteristics of light, sound, and electromagnetic waves to measure length and distance are used to carry out real estate mapping and measurement work.

[0003] However, during use, since real estate surveying and mapping requires a lot of measuring work, staff usually put many measuring tools in a tool box for centralized carrying. As the staff moves, various measuring tools are easy to collide with each other in the tool box, which can easily cause damage to the rangefinder; or the staff are required to carry the rangefinder around. During the long-term holding process, if the staff's hands are unstable, the rangefinder is prone to fall and be damaged. Utility Model Content

[0031] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] like Figure 1 to Figure 3 As shown, this embodiment provides a handheld rangefinder, which mainly includes an instrument body 1. The instrument body 1 includes a display screen 11, a laser emitter 12, and a laser sensor 13. The measurement work is completed through the interaction between the laser emitter 12 and the laser sensor 13.

[0033] The instrument body 1 is provided with a protective shell 2, in which the instrument body 1 is located. When the instrument body 1 falls to the ground or collides with other measuring props while being moved around in various properties, the impact force generated by the collision will first act on the protective shell 2, thereby dispersing part of the impact force for the instrument body 1 and reducing the possibility of damage to the instrument body 1.

[0034] An opening 28 for observing the display screen 11 is provided on the protective shell 2. The opening 28 passes through the end of the protective shell 2 away from the display screen 11, so that the staff can press the button on the instrument body 1 to perform real estate surveying and mapping work, and watch the display screen 11 to view the measurement results. The protective shell 2 is slidably connected to the instrument body 1 to avoid the existence of the protective shell 2 interfering with the normal real estate surveying and mapping work.

[0035] Moreover, after the protective shell 2 slides, it can also shield the nearby light source, reduce the influence of the external light source on the laser sensor 13 when receiving the laser, and make the handheld rangefinder more practical and the measurement result more accurate.

[0036] The sliding connection between the protective shell 2 and the instrument body 1 is preferably an embedded sliding connection. For example, a sliding groove 14 is provided on the instrument body 1, and a sliding body 23 is provided on the protective shell 2. The sliding body 23 is slidingly connected in the sliding groove 14. With the help of the embedded connection between the sliding body 23 and the sliding groove 14, the sliding connection between the protective shell 2 and the instrument body 1 is made more stable; and the maximum moving distance of the protective shell 2 is limited to prevent the protective shell 2 from detaching from the instrument body 1. The overall structure of this embodiment is more stable.

[0037] Sliding grooves 14 are provided on both sides of the instrument body 1, and each sliding groove 14 is slidably connected with a sliding body 23, so that the sliding of the protective shell 2 is more balanced and stable, and the sliding body 23 is prevented from being subjected to unilateral force during the sliding process, which causes the sliding body 23 to be easily deformed, resulting in the sliding of the protective shell 2 being stuck or even unable to slide; and an electrostatic suction cup 3 for fixing the sliding body 23 is provided between each sliding body 23 and the sliding groove 14, and the protective shell 2 is fixed by means of the electrostatic suction force of the electrostatic suction cup 3, which is convenient for the real estate surveying and mapping work of this embodiment. The electrostatic suction cup 3 is electrically connected to the control system of the instrument body 1, which is convenient for directly controlling the electrostatic suction cup 3 to fix the protective shell 2. The specific connection method between the electrostatic suction cup 3 and the instrument body 1 is shown according to the operating system of the selected electrostatic suction cup 3, and will not be repeated in this embodiment.

[0038] like Figures 4 to 6As shown, each sliding body 23 in this embodiment includes a sliding part 231 and a linkage part 232. The linkage part 232 is fixedly connected to the protective shell 2 and slidably connected in the sliding part 231. The sliding part 231 is slidably connected in the sliding groove 14. The sliding direction of the linkage part 232 is perpendicular to the sliding direction of the sliding part 231, so that when the protective shell 2 is subjected to a force perpendicular to the sliding groove 14, it can slide with the help of this force and disperse this force by moving, that is, it plays a buffering role against external impact force, thereby improving the protection effect of this embodiment, and an elastic member 233 is provided between the sliding part 231 and the linkage part 232. The elastic member 233 is preferably an elastic element with a high load capacity such as a spring, and the elastic potential energy of the elastic member 233 is used to further improve the protection effect of this embodiment.

[0039] At the same time, if Figure 1-2 As shown, the protective shell 2 in this embodiment is provided with a limiting belt plate 21, which is rotatably connected to the protective shell 2, and a fixing clamp 22 for fixing the limiting belt plate 21 is provided between the protective shell 2 and the limiting belt plate 21, that is, the limiting belt plate 21 is fixed on the protective shell 2 through the fixing clamp 22, and cooperates with the restraining effect of the sliding groove 14 on the sliding body 23 to prevent the protective shell 2 from slipping in the non-working state, so that the instrument body 1 can no longer be protected by the protective shell 2.

[0040] And because the sliding groove 14 itself has a restraining effect on the sliding body 23, when the protective shell 2 moves to the position of the protective instrument body 1, the sliding body 23 should be just at the extreme distance position in a moving direction. In this way, it is only necessary to set a limiting belt plate 21 at one end of the protective shell 2 to achieve the limiting restraint effect on the protective shell 2, thereby reducing the economic cost; the limiting belt plate 21 is located at the end of the protective shell 2 away from the laser emitter 12 to prevent the existence of the limiting belt plate 21 from interfering with the emission and reception of the laser, thereby ensuring that the detection work of this embodiment can be carried out normally.

[0041] The protective shell 2 is provided with a rotating frame 25 for rotatably connecting the limiting belt plate 21, and the fixing card 22 is located on the side of the protective shell 2 away from the rotating frame 25, so that after controlling the fixing card 22 to cancel the fixation of the limiting belt plate 21, the protective shell 2 or the instrument body 1 can be directly controlled to move, without moving the limiting belt plate 21 to a specified position before controlling the movement of the protective shell 2 or the instrument body 1, thereby improving the convenience of this embodiment.

[0042] At the same time, there are a number of limiting strips 21 , and each limiting strip 21 is arranged in sequence along the linear direction, which fully ensures the restraining effect of the limiting strip 21 on the protective shell 2 and the instrument body 1 , and ensures the restraining effect of the limiting strip 21 .

[0043] like Figure 7-8As shown, the fixing card 22 in this embodiment is composed of Velcro, and the fixing card 22 includes a sub-sticker 221 and a mother sticker 222. The protective shell 2 is provided with a mounting groove 26 for fixing the mother sticker 222. The sub-sticker 221 is fixedly connected to the limiting strip 21, that is, with the help of the automatic adhesion effect of the Velcro, when the limiting strip 21 is moved to the corresponding position, it can be automatically fixed, which is very convenient and quick; and the mother sticker 222 is fixed on the protective shell 2 in a sunken position, which is also convenient for hiding the fixing card 22 in this embodiment, thereby improving the overall aesthetics of this embodiment.

[0044] At the same time, the projection surface of the limiting belt plate 21 on the horizontal plane presents a "U"-shaped structure, that is, the fixed clamp 22 and the rotating frame 25 are respectively located at the two ends of the "U"-shaped structure, so that when the limiting belt plate 21 is subjected to force, the force it bears can be supported more evenly and balanced; and the instrument body 1 is just located at the center of the "U"-shaped structure, which fully ensures the force balance of the limiting belt plate 21, makes the force of this embodiment more balanced, and avoids the instrument body 1 breaking through the limiting belt plate 21 when the present embodiment is subjected to force, thereby destroying the overall structure of this embodiment.

[0045] Auxiliary surfaces 211 are provided at the top of both sides of the limiting strip 21. The auxiliary surfaces 211 are arc-shaped structures, and the length of the mounting groove 26 is longer than the length of the two ends of the limiting strip 21, so that it is convenient for the staff's fingers to be inserted into the gap between the limiting strip 21 and the mounting groove 26, and it is convenient for the limiting strip 21 to be bent under force, so as to facilitate the removal of the sub-sticker 221 from the mother sticker 222, thereby making the fixing card 22 in this embodiment easy to use.

[0046] like Figure 1 to Figure 4 As shown, in this embodiment, a buffer pad 24 is provided between the protective shell 2 and each limiting strip plate 21 and the instrument body 1. The buffer pad 24 is preferably made of an elastic material such as rubber. Under the physical partition buffering effect of the protective shell 2, the effect of elastic buffering is added. The elastic material is deformed by force, thereby absorbing and dispersing the impact energy, reducing the impact of the impact on the instrument body 1 itself; and, due to the addition of the buffer pad 24, the buffering range of the impact force of this embodiment is further expanded, so that the instrument body 1 that is impacted can have a larger buffering range to obtain a smooth deceleration process, reducing the damage to the instrument body 1 caused by the impact.

[0047] Both sides of the protective shell 2 are provided with anti-skid grips 27 for easy holding. The anti-skid grips 27 are provided with anti-skid patterns for increasing friction, so as to prevent the staff from sweating in the palms due to holding the present embodiment for a long time, thereby causing the hands to slip, causing the present embodiment to fall out of the hand and fall to the ground, thereby avoiding damage to the rangefinder from the root.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
