Description

Technical Field

[0001] The utility model relates to the technical field of laser distance measurement, in particular to a drop-proof laser distance meter. Background Art

[0002] A laser rangefinder is an instrument that uses a certain parameter of a modulated laser to measure the distance to a target. It has the characteristics of high measurement accuracy and a wide measurement range. According to a construction engineering inspection laser rangefinder described in Chinese patent document CN202320716452.4, the disclosed technical solution is to place the laser rangefinder horizontally on the ground so that it is in contact with the ground, which makes it easier for the laser rangefinder to slide on the ground when it moves, reduces the friction between the support frame and the ground, prevents damage to the bottom of the laser rangefinder, and improves the protection of the laser rangefinder.

[0003] According to the disclosed technical solution, in order to improve the protection effect, the laser rangefinder in the prior art will install an anti-collision shell on the side, but the display screen part on the surface of the laser rangefinder cannot provide shielding protection when in use. Therefore, once the display screen collides with the ground after falling, it will still be damaged. On the other hand, the laser probe part on the laser rangefinder cannot provide shielding, so there is also a lack of effective protection solutions. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a drop-proof laser rangefinder to solve the problems raised in the above-mentioned background technology. The present invention can provide targeted protection for the display screen and the laser probe part, thereby enhancing the protection effect.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a drop-proof laser rangefinder, comprising a laser rangefinder body, the laser rangefinder body comprising a shell, a grip assembly, a top protection mechanism and a closed bracket, a display screen is arranged on the surface of the shell, a grip assembly is installed on the bottom of the shell, a bottom plate is installed on the bottom of the grip assembly, a top protection mechanism is installed on the top of the shell, a first spring rod is installed on the inner side of the top protection mechanism, a laser probe is arranged on the top of the shell, and the closed bracket is installed on the top of the laser probe.

[0007] Furthermore, the top of the buffer spring is fixedly connected to the bottom end of the shell, one side of the bottom plate is connected to a linkage bracket, and a vertical pole is installed on the top of the linkage bracket.

[0008] Furthermore, the protective plate is installed on the top of the vertical pole, and the protective plate is arranged on the surface and rear end of the shell. The protective plate is contracted by a buffer spring to block the surface of the display screen, and the surface size of the protective plate is larger than the surface size of the display screen.

[0009] Furthermore, the top protection mechanism includes a top plate and a first spring rod, the rod inside the first spring rod is inserted into the interior of the shell, an inclined plate is provided on one side of the laser probe, and a light guide hole is installed on the top of the shell.

[0010] Furthermore, the laser probe is installed inside the light guide hole, a convex limiting structure is installed on the side of the shell, a through hole is opened on the top of the top plate, and the laser probe emits a laser beam outward from the inside of the through hole.

[0013] Beneficial effects of the utility model:

[0014] The anti-fall laser rangefinder is equipped with a grip assembly at the bottom. A protective plate is installed on the grip assembly. When a fall occurs, the contraction effect of the buffer spring can be used to pull the protective plate up and quickly cover the display screen. Therefore, it can effectively prevent the display screen from directly contacting the ground after a fall and causing damage.

[0015] The drop-proof laser rangefinder is equipped with a top protection component on the top of the shell, so that after falling, it can provide effective buffering effect to the top, bottom and each corner of the shell, and will not affect the use of the control panel on the surface of the shell and the display effect of the display screen, taking into account both protection performance and flexibility of use.

[0016] The drop-proof laser rangefinder is equipped with a closed bracket inside the top protection mechanism. Therefore, when the top protection mechanism collides with the ground after falling, it can automatically trigger the sealed bracket to move synchronously. In conjunction with the inclined plate on the side of the laser probe, the top of the laser probe can be automatically shielded to prevent dust and gravel after the collision from contacting the laser probe, thereby reducing the probability of scratches on the laser probe.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: a drop-proof laser rangefinder, comprising a laser rangefinder body, the laser rangefinder body comprising a shell 1, a grip assembly 3, a top protection mechanism 4 and a closed bracket 18, a display screen 2 is arranged on the surface of the shell 1, a grip assembly 3 is installed at the bottom of the shell 1, a bottom plate 9 is installed at the bottom of the grip assembly 3, a top protection mechanism 4 is installed at the top of the shell 1, a first spring rod 14 is installed on the inner side of the top protection mechanism 4, a laser probe 16 is arranged on the top of the shell 1, and the closed bracket 18 is installed on the top of the laser probe 16. When the drop-proof laser rangefinder is used, the grip assembly 3 is manually picked up, and the entire instrument can be controlled by holding the handle 8. When measuring, the laser probe 16 on the top of the shell 1 is irradiated toward the preset measuring point, and the distance data can be obtained through the photoelectric module inside the laser probe 16. When it falls during use, the bottom holding component 3 can automatically block and protect the display screen 2, and the top protection mechanism 4 cooperates with the closed bracket 18 to provide targeted shielding protection for the laser probe 16. The laser probe 16 and the internal matching photoelectric module are both existing mature technologies. The distance measurement process can be realized by selecting a laser probe 16 of corresponding specifications according to the specific distance measurement range.

[0024] In this embodiment, the holding assembly 3 includes a handle 8 and a protective plate 12, a telescopic sleeve 6 is installed at the bottom of the shell 1, the bottom end of the telescopic sleeve 6 is inserted with the handle 8, the top of the handle 8 is connected to the buffer spring 7, the bottom plate 9 is installed at the end of the handle 8, the top of the buffer spring 7 is fixedly connected to the bottom end of the shell 1, one side of the bottom plate 9 is connected to a linkage bracket 10, the top of the linkage bracket 10 is installed with a vertical pole 11, the protective plate 12 is installed on the top of the vertical pole 11, the protective plate 12 is arranged on the surface and rear end of the shell 1, the protective plate 12 is contracted by the buffer spring 7 to block the surface of the display screen 2, and the surface size of the protective plate 12 is larger than the surface size of the display screen 2. A grip assembly 3 is installed at the bottom. A protective plate 12 is installed on the grip assembly 3. When a fall occurs, the protective plate 12 can be pulled up by utilizing the contraction effect of the buffer spring 7, and a portion of the display screen 2 can be quickly blocked. Therefore, it can effectively prevent the display screen 2 from directly contacting the ground after the fall and causing damage. Specifically, in the initial state, the buffer spring 7 will pull the handle 8 to move upward, and embed the handle 8 into the interior of the telescopic sleeve 6 in a static state, and the protective plate 12 will partially cover the surface of the display screen 2. When in use, it is necessary to pull the bottom plate 9 to drive the handle 8 to move out from the interior of the telescopic sleeve 6, and limit the handle 8 by holding it on the handle 8. At this time, the protective plate 12 can be removed from the surface of the display screen 2 for easy display and reading. After a fall occurs, the lost hand blocks the telescopic sleeve 6 and the bottom plate 9, so it can automatically reset under the action of the buffer spring 7, so as to automatically complete the shielding process of the display screen 2 at the moment of falling.

[0025] In this embodiment, the top protection mechanism 4 includes a top plate 13 and a first spring rod 14, the rod inside the first spring rod 14 is inserted into the inside of the housing 1, an inclined plate 17 is provided on one side of the laser probe 16, a light guide hole 15 is installed on the top of the housing 1, the laser probe 16 is installed inside the light guide hole 15, an outwardly convex limiting structure is installed on the side of the housing 1, a through hole 5 is opened on the top of the top plate 13, and the laser probe 16 emits the laser beam outward from the inside of the through hole 5. A top protection component is installed on the top of the housing 1, so that after falling, it can provide an effective buffering effect to the top, bottom and each corner of the housing 1, and will not affect the use of the control panel on the surface of the housing 1 and the display effect of the display screen 2, taking into account both the protection performance and the flexibility of use. Specifically, after falling, after the top plate 13 contacts the ground, the first spring rod 14 can be pressed down to provide a buffering effect to the top plate 13 part.

[0026] In this embodiment, the closed bracket 18 includes a translation channel 20 and a cross frame 22. A fixing rod 19 is installed on the top of the translation channel 20. The top of the fixing rod 19 is fixedly connected to the inner wall of the top plate 13. A roller 23 is installed in the middle of the cross frame 22. A baffle 24 is installed at one end of the inner side of the cross frame 22. Both ends of the baffle 24 and the cross frame 22 are inserted into the interior of the translation channel 20, and a second spring rod 21 is installed at the end of the cross frame 22. The bottom of the roller 23 is aligned with the surface of the inclined plate 17. A closed bracket 18 is provided inside the top protection mechanism 4. Therefore, when part of the top protection mechanism 4 collides with the ground after falling, it can automatically trigger the closed bracket to move synchronously, and cooperate with the inclined plate 17 on the side of the laser probe 16 to automatically shield the top of the laser probe 16 to prevent dust and gravel from contacting the laser probe 16 after the collision, thereby reducing the probability of scratches on the laser probe 16. Specifically, when the top plate 13 contacts the ground downward and collides with it when falling, the top plate 13 and the inner closed bracket 18 will move. At this time, the roller 23 on the closed bracket 18 is pressed on the inclined plate 17, and the roller 23 is pulled horizontally by the guidance of the inclined plate 17 until the baffle 24 on one side is moved toward the top of the laser probe 16, thereby achieving a shielding and covering effect on the surface of the laser probe 16.
