Description

Technical Field

[0001] The utility model relates to the technical field of rangefinders and altimeters, and particularly relates to a laser rangefinder and altimeter with a Beidou positioning function. Background Technique

[0002] A laser rangefinder and altimeter with a Beidou positioning function is a measuring device with automatic positioning. Devices such as a laser emitter and a laser receiver are installed inside. When measuring, the laser emitter emits laser light to the outside. At this time, the laser receiver can receive the laser light reflected by an object, and the distance and height can be calculated through corresponding algorithms, which is very convenient to use.

[0003] When using a portable altimeter, the operator needs to hold both sides of the altimeter with both hands. There are two groups of lenses arranged at the front end of the altimeter. Since there is no protective structure installed outside the lenses, when the operator moves the altimeter, the lenses are easily affected by external objects and are likely to be damaged. Moreover, there is no structure installed on both sides of the altimeter to assist the operator in holding it. When the operator uses it, it is easy to accidentally cause the altimeter to slip, which is likely to cause damage to the altimeter. To solve this technical problem, the utility model proposes a laser rangefinder and altimeter with a Beidou positioning function. Summary of the Utility Model

[0024] A fixing frame 2 is fixedly installed on the outside of the altimeter body 1. A strap 3 is rotatably connected to the outer surface of the fixing frame 2. One end of the strap 3 is fixedly installed with an elastic pull rope 4. The palm of the staff can be fixed through the strap 3. When in use, the staff holds one side of the altimeter body 1 with the palm. Under the action of the elastic pull rope 4, the strap 3 has the ability to restore its position. At this time, the strap 3 can fix the palm of the staff, reduce the risk of the altimeter body 1 slipping, and at this time the staff can hold and use it with one hand.

[0025] One end of the altimeter body 1 is fixedly installed with a fixing box 7. A fixing shaft 8 is rotatably connected to the inside of the fixing box 7. A gear 9 is fixedly installed on the outer surface of the fixing shaft 8. The gear 9 can be fixed through the fixing shaft 8 and connected to the inside of the fixing box 7. A fixing plate 10 is fixedly installed on the outer surface of the fixing shaft 8. One end of the fixing plate 10 is fixedly installed with a protective cover 11. The rotation of the gear 9 can control the rotation of the protective cover 11. At this time, the protective cover 11 can block the lens inside the altimeter body 1 and can be opened for measurement use. A chute 15 is opened inside the fixing box 7. The outer surface of the protective cover 11 is slidably connected to the inside of the chute 15. When the gear 9 rotates, the protective cover 11 can rotate inside the chute 15. A baffle is fixedly installed on the inner wall of the chute 15. The vertical angle of the fixing plate 10 can be controlled through the cooperation of the baffle and the limiting groove 12.

[0026] A limiting groove 12 is opened inside the fixing plate 10. A toothed plate 13 is slidably connected to the inside of the limiting groove 12. There are two groups of gears 9 and toothed plates 13. The two groups of gears 9 are symmetric with each other, and the two groups of toothed plates 13 are arranged up and down in the opposite direction. The moving position of the toothed plate 13 can be limited through the limiting groove 12. Under the action of the limiting groove 12, the toothed plate 13 can move linearly, improving the stability of the toothed plate 13 during movement. The teeth of the toothed plate 13 mesh with the teeth of the gear 9. The rotation of the toothed plate 13 can control the rotation of the gear 9, and the opening and closing of the protective cover 11 can be controlled through the movement of the toothed plate 13.

[0027] A guiding block 14 is fixedly installed at one end of the altimeter body 1. The outer surface of the elastic pull rope 4 is slidably connected to the inside of the guiding block 14. The direction of the elastic pull rope 4 can be controlled through the guiding block 14, which is convenient for controlling the movement of the elastic pull rope 4 when moving the strap 3.

[0028] A fixing rope 5 is fixedly installed at one end of the elastic pull rope 4, and the outer surface of the fixing rope 5 is slidably connected to the inside of the fixing box 7. When the strap 3 moves, the fixing rope 5 can be pulled to move. A connecting plate 16 is fixedly installed on one side of the tooth plate 13, and one end of the fixing rope 5 is connected to one side of the connecting plate 16. At this time, the fixing rope 5 can drive the connecting plate 16 to move, and can further drive the tooth plate 13 to move. At this time, the protective cover 11 can be automatically opened.

[0029] The fixing rope 5 is covered with a spring 6 on the outside, one end of the spring 6 is connected to the inner wall of the fixing box 7, and the other end of the spring 6 is connected to one side of the connecting plate 16. When the strap 3 is not subjected to external force, the spring 6 can push the tooth plate 13 to reset, and the protective cover 11 can be automatically closed.

[0030] A mounting plate 17 is fixedly installed on one side of the toothed plate 13, and a positioning rod 18 is slidably connected inside the mounting plate 17. A spring 19 is sleeved on the outside of the positioning rod 18, and one end of the spring 19 is connected to one side of the mounting plate 17, and the other end of the spring 19 is connected to the outer surface of the positioning rod 18. The positioning rod 18 can be limited by the mounting plate 17, and a baffle is installed on the outside of the positioning rod 18. One end of the positioning rod 18 can be limited by the baffle. Under the action of the spring 19, one end of the positioning rod 18 will move to the outside of the mounting plate 17.

[0031] An insertion rod 20 is fixedly installed at one end of the positioning rod 18, and the outer surface of the insertion rod 20 contacts the inner wall of the fixing box 7. A slot 21 is provided inside the fixing box 7. The outer surface of the insertion rod 20 is slidably connected to the inside of the slot 21. When the altimeter body 1 needs to be placed for use, the tooth plate 13 can be controlled to move. When the insertion rod 20 moves to the position of the slot 21, the insertion rod 20 can enter the inside of the slot 21 under the push of the spring 19, so that the position of the tooth plate 13 can be fixed.

[0032] When in use, the staff holds one side of the altimeter body 1, and the strap 3 is stretched open by the palm of the hand. The strap 3 can control the movement of the fixing rope 5 and drive the tooth plate 13 to move. When the tooth plate 13 moves, it can drive the gear 9 to rotate. At this time, the protective cover 11 is rotated and opened. Under the action of the elastic pull rope 4 and the spring 1 6, the strap 3 can be subjected to the force of resetting. At this time, the strap 3 can fit tightly with the palm of the user, which can reduce the risk of the altimeter body 1 falling. When the altimeter body 1 slips, the spring 1 6 can push the tooth plate 13 to move. At this time, the tooth plate 13 can control the gear 9 to reset and further drive the protective cover 11 to reset to protect the lens. Under the action of the spring 2 19, the insertion rod 20 can enter the interior of the slot 21, so as to fix the position of the tooth plate 13, thereby meeting more usage requirements.
