Description

Technical Field

[0001] The utility model relates to the field of forestry, and particularly to a tree height measuring device. Background Art

[0002] The Haguang altimeter is mainly used for measuring height, distance and angle. The Haguang altimeter is a digital altimeter that adopts advanced sensing technology and software algorithms, and has high measurement accuracy. It is applicable to the measurement of tree height in forestry surveys, and can also be used in occasions such as electric power, iron towers, freight transportation, communication, railways, etc. that require distance measurement, angle measurement and height measurement. The Haguang altimeter adopts advanced sensing technology and software algorithms to ensure the accuracy of measurement results. At the same time, the Haguang altimeter adopts a gun-shaped structure in appearance, which is convenient to carry and suitable for field operations. The Haguang altimeter is equipped with an OLED screen, and the display effect is clear, and the measurement data is clear at a glance.

[0003] However, the existing Haguang altimeter for tree height still has the following problems in the process of use:

[0004] The measurement probe at the front end of the existing Haguang altimeter will emit a laser beam during measurement. It is strictly prohibited to aim the front end of the instrument at the human eye at any time to avoid eye burns. Since the Haguang altimeter is started by the measurement key during use, the Haguang altimeter lacks a protection mechanism. When the Haguang altimeter falls to the ground and the measurement key is accidentally touched, the measurement probe emits a laser beam, which is likely to cause a safety hazard. Therefore, it is very necessary to involve a tree height measuring device in the existing forestry field. Content of the Utility Model

[0005] In order to make up for the deficiencies of the existing technology, when the existing Haguang altimeter falls to the ground and the measurement key is accidentally touched, and the measurement probe emits a laser beam, which is likely to cause a safety hazard, the utility model proposes a tree height measuring device.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a tree height measuring device, including a Haguang altimeter main body, an installation block is fixedly assembled at the bottom of the Haguang altimeter main body, guiding rods are symmetrically and fixedly assembled on the installation block, limiting blocks are fixedly assembled at one ends of the two guiding rods, a movable block is movably assembled on the two guiding rods, an installation rod is fixedly assembled on the movable block, an extension rod is fixedly assembled at one end of the installation rod, a connecting rod is fixedly assembled at one end of the extension rod, a protective baffle is fixedly assembled at one end of the connecting rod, and an installation plate is fixedly assembled on the movable block at the end of the protective baffle close to the Haguang altimeter main body.

[0007] Preferably, fixed blocks are symmetrically and fixedly assembled at the bottom of the Huguang light measuring instrument body. The fixed blocks are located on one side of the mounting blocks. Guide rods are symmetrically and fixedly assembled between the two fixed blocks. A pulling block is movably assembled on the two guide rods. Telescopic springs are assembled on the guide rods, and the two ends of the telescopic springs are fixedly assembled with the fixed blocks and the pulling block respectively.

[0008] Preferably, a fixing plate is fixedly assembled on the side surface of the pulling block. An adjusting rod is movably assembled on the fixing plate, and the other end of the adjusting rod is movably assembled with the mounting plate.

[0009] Preferably, a pull rope is fixedly assembled at the bottom of the pulling block, and a pull ring is fixedly assembled at one end of the pull rope.

[0010] Preferably, a handle is fixedly assembled at the bottom of the Huguang light measuring instrument body. A measuring key is fixedly assembled on the handle. The measuring key is close to the pull ring. A sight is fixedly assembled on the upper surface of the Huguang light measuring instrument body.

[0011] Preferably, a measuring probe is arranged at one end of the Huguang light measuring instrument body. The protective baffle is close to the measuring probe. A display screen is fixedly assembled at the other end of the Huguang light measuring instrument body.

[0012] The beneficial effects of the present utility model are as follows:

[0013] By pulling the pull ring with the index finger in the present utility model, the pull rope drags the pulling block to move on the guide rod, and the telescopic spring is stretched. Under the action of the adjusting rod, the movable block moves on the two guide rods. The movable block drives the extension rod on the mounting rod to move, and the extension rod drives the protective baffle on the connecting rod to move, so that the protective baffle moves away from the measuring probe, presses the measuring key, aligns the top of the tree through the sight, the measuring probe emits a laser beam, and the measuring probe measures the height data of the tree and feeds it back to the display screen for display. When the Huguang light measuring instrument body falls to the ground, under the action of the telescopic spring, the protective baffle blocks the measuring probe, and even if the measuring key is accidentally touched, it can avoid the safety hazards caused by the measuring probe and improve the use effect.

At one end of the protective baffle 30 close to the main body 10 of the Haguang light measuring instrument, an installation plate 51 is fixedly assembled on the activity block 41. At the bottom of the main body 10 of the Haguang light measuring instrument, fixed blocks 40 are symmetrically and fixedly assembled. The fixed blocks 40 are located on one side of the installation block 31. Between the two fixed blocks 40, guide rods 52 are symmetrically and fixedly assembled. A pulling block 53 is movably assembled on the two guide rods 52. A telescopic spring 60 is fixedly assembled between the fixed block 40 and the pulling block 53.

An adjusting rod 62 is movably assembled on the fixed plate 61. The other end of the adjusting rod 62 is movably assembled with the installation plate 51. At the bottom of the pulling block 53, a pull rope 21 is fixedly assembled. At one end of the pull rope 21, a pull ring 22 is fixedly assembled. When the index finger pulls the pull ring 22, the pull rope 21 drags the pulling block 53 to move on the guide rod 52, and the telescopic spring 60 is stretched. Under the action of the adjusting rod 62, the activity block 41 moves on the two guide rods 32. The activity block 41 drives the extension rod 43 on the installation rod 42 to move. The extension rod 43 drives the protective baffle 30 on the connecting rod 50 to move.

[0029] Refer to Figure 1 - Figure 3 , At the bottom of the main body 10 of the Haguang light measuring instrument, a handle 11 is fixedly assembled.

Under the action of the adjusting rod 62, the movable block 41 moves on the two guide rods 32. The movable block 41 drives the extension rod 43 on the mounting rod 42 to move, and the extension rod 43 drives the protective baffle 30 on the connecting rod 50 to move, so that the protective baffle 30 moves away from the measuring probe 23, pressing the measuring key 20. Align the top of the tree through the sight 13, the measuring probe 23 emits a laser beam, and the measuring probe 23 measures the height data of the tree and feeds it back to the display screen 12 for display. When the main body 10 of the haze light meter falls to the ground, under the action of the telescopic spring 60, the protective baffle 30 blocks the measuring probe 23. Even if the measuring key 20 is accidentally touched, the safety hazard caused by the measuring probe 23 can be avoided, improving the use effect.
