[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] like Figures 1 to 9 As shown, the present invention provides a forestry measuring device, including a top rod 1, a bottom rod 2 at the bottom end of the top rod 1, a handrail 3 fixedly installed at the top end of the top rod 1, a pusher 4 fixedly installed at the top end of the bottom rod 2, an air chamber 5 at the bottom end of the top rod 1, the top end of the pusher 4 being movably connected to the air chamber 5, a return spring 6 fixedly installed at the top end of the pusher 4, and a ground-inserting rod 10 fixedly installed at the bottom end of the top rod 1. Locking chambers 7 are provided on both the left and right sides of the base rod 2. Locking rods 8 are slidably connected to the inner cavity of the locking chambers 7. Locking blocks 9 are fixedly installed at the bottom end of the locking rods 8. Connecting blocks 11 are fixedly installed at the bottom end of the base rod 2. A base plate 12 is rotatably connected to the middle of the connecting blocks 11. A gear 13 is fixedly installed on the side of the base plate 12 near the center of the connecting blocks 11. Fixed shafts 14 are fixedly installed on both the left and right sides of the bottom end of the top rod 1. Positioning plates 15 are movably sleeved on the surface of the fixed shafts 14. Positioning shafts 16 are fixedly installed at the bottom end of the positioning plates 15. Positioning holes 17 are opened at the top end of the bottom rod 2.
[0021] By opening a locking chamber 7 inside the base rod 2 and setting a sliding pusher 4 inside the air chamber 5, the top rod 1 can be adjusted to a vertical state by rotating the top rod 1 and the base rod 2. When the top rod 1 is pressed down, the pusher 4 moves upward in the air chamber 5, squeezing the air in the air chamber 5 into the handrail 3. The positioning plate 15 is moved by the finger, causing the positioning plate 15 to drive the positioning shaft 16 into the positioning hole 17, thus fixing the top rod 1 and the base rod 2. When the handrail 3 is aligned with the locking chamber 7, air is delivered into the locking chamber 7 to press down the locking rod 8, causing the locking block 9 to engage with the gear 13, locking the gear 13, and thus fixing the base rod 2 and the base plate 12. This achieves quick and convenient leveling and improves measurement efficiency.
[0022] Among them, the locking block 9 is located below the bottom rod 2, the locking block 9 is engaged with the gear 13, and the ground rod 10 is movably sleeved inside the bottom rod 2; After the test is completed, due to the relative movement between the bottom rod 2 and the top rod 1, the top rod 1 can drive the ground insertion rod 10 to slide inside the bottom rod 2. At this time, the ground insertion rod 10 is automatically retracted into the bottom rod 2 to avoid injury from the sharp cone at the end of the ground insertion rod 10, thus improving the safety of the device.
[0023] Among them, the bottom plate 12 has a waist-shaped groove in the middle, and the projection of the bottom rod 2 in the horizontal direction is located in the waist-shaped groove; The waist-shaped groove can prevent the base plate 12 from interfering with the base rod 2 when rotating, thus enabling it to cope with different terrains.
[0024] Among them, the handrail 3 has an air passage in the middle, the air chamber 5 is connected to the air passage, and the fixed shaft 14 is located in the middle of the handrail 3. The handrail 3 has an air duct inside. After the top rod 1 and the bottom rod 2 are in full contact, the handrail 3 can be directly connected to the locking chamber 7 to achieve automatic air intake.
[0025] Among them, a connecting pipe 18 is fixedly installed at the top of the handrail 3, a plug shaft 19 is movably connected to the bottom of the connecting pipe 18, an extension rod 20 is fixedly installed at the bottom of the plug shaft 19, a push rod 21 is fixedly installed at the end of the positioning piece 15 away from the bottom rod 2, a mounting base 29 is fixedly installed at the top of the top rod 1, a protective cover 28 is hinged to the top of the mounting base 29, a lifting shaft 24 is movably connected to the top of the connecting pipe 18, a support component 30 is fixedly installed at the bottom of the mounting base 29, a movable frame 25 is fixedly installed at the top of the support component 30, a sliding frame 26 is slidably connected to the front and rear ends of the movable frame 25, and a connecting piece 27 is rotatably connected to the top of the sliding frame 26. While the fixed shaft 14 is moved, the push rod 21 is moved, so that the inclined surface of the push rod 21 is placed below the extension rod 20. At this time, the blocking shaft 19 falls down a certain distance under its own weight, thereby connecting the handrail 3 and the connecting pipe 18. The compressed air in the handrail 3 will enter the connecting pipe 18 and push the lifting shaft 24 upward. Through the transmission of the moving frame 25, the sliding frame 26 and the connecting piece 27, the protective cover 28 is automatically opened. When the device is being carried, the protective cover 28 is in the closed state for protection, to prevent the laser measuring instrument 33 from being damaged by collision in the forest. When the protective cover 28 is closed, the length between the bottom rod 2 and the top rod 1 reaches the maximum length value.
[0026] Among them, a limiting piece 23 is fixedly installed at the top end of the connecting pipe 18, and a support ring 22 is fixedly installed in the inner cavity of the connecting pipe 18, with the support ring 22 located below the limiting piece 23; The support ring 22 and the limiting piece 23 are provided to support the blocking shaft 19 and prevent it from shaking.
[0027] Among them, the lifting shaft 24 is fixed to the moving frame 25, the connecting piece 27 is inclined and its top is fixed to the protective cover 28, and the support assembly 30 consists of a telescopic rod and a spring sleeved on the surface of the telescopic rod. The inclined connecting piece 27 can better open and close the protective cover 28. The sliding frame 26 slides within the moving frame 25. During the movement of the protective cover 28, the connection position between the sliding frame 26 and the connecting piece 27 will change when placed horizontally to avoid interference between the moving frame 25 and the connecting piece 27.
[0028] Among them, the bottom end of the plug shaft 19 is inserted into the handrail 3, and the plug shaft 19 seals the connecting pipe 18 and the handrail 3; The connection and closure of the connecting pipe 18 and the handrail 3 are controlled by setting the up and down movement of the blocking shaft 19, so as to avoid the situation where the protective cover 28 opens and hits the user when the user is adjusting the angle and locking, because the user's attention is focused on the level bubble 36.
[0029] Among them, adjustable telescopic rods 31 are fixedly installed at both the front and rear ends of the inner cavity of the protective cover 28. A brush 32 is fixedly installed at the end of the adjustable telescopic rod 31 near the axis of the top rod 1. A fixed seat 34 is fixedly installed at the bottom of the mounting base 29. A rotating table 35 is rotatably connected to the top of the fixed seat 34. A laser measuring instrument 33 is detachably installed on the rotating table 35 by bolts. A brush 32 is connected inside the protective cover 28 via an adjustable telescopic rod 31. The adjustable telescopic rod 31 can be freely adjusted in length, allowing the brush 32 to contact the lens of the laser measuring instrument 33. When the protective cover 28 is opened and closed, the lens of the laser measuring instrument 33 can be wiped by the contact between the brush 32 and the lens, preventing dust from affecting the measurement. The tilt angle of the laser measuring instrument 33 can be adjusted by the rotational connection between the rotary table 35 and the fixed base 34 to facilitate measurement. Furthermore, the laser measuring instrument 33 and the rotary table 35 are connected by bolts, allowing for the installation of a GPS measuring instrument after disassembly, thereby increasing the applicability of the device.
[0030] Among them, a spirit level 36 is fixedly installed on the surface of the top rod 1; By setting the bubble level 36, the tilt state of the push rod 1 can be calibrated, and the real-time tilt state of the push rod 1 can be indicated, making it easy to adjust.
[0031] Working principle and usage process of this invention: When in use, first make the base plate 12 contact the ground, then the user steps on the base plate 12 with his / her foot to make the base plate 12 stick to the ground and cannot move. Then, rotate the base rod 2 and the handrail 3 through the level bubble 36 until the level bubble 36 indicates horizontal. Then, holding the handrail 3, pull down the top rod 1 through the handrail 3. At this time, the top of the pusher 4 slides upward in the air chamber 5, squeezing the air in the air chamber 5 into the handrail 3 for compression. When the top rod 1 and the bottom rod 2 are in complete contact, the bottom end of the handrail 3 is aligned with the locking chamber 7. At this time, the compressed air squeezes the locking rod 8 downward through the locking chamber 7, thereby driving the locking block 9 to engage with the gear 13, preventing the gear 13 from continuing to rotate, thus fixing the base plate 12 and the bottom rod 2. Then, use your fingers to move the positioning piece 15, causing the positioning piece 15 to drive the positioning shaft 16 to insert into the positioning hole 17. Then, release the handrail 3. Since the return spring 6 is in a compressed state, it will exert an upward movement tendency on the top rod 1, thereby squeezing the positioning shaft 16 inside, thus fixing the top rod 1 and the bottom rod 2. At the same time, the movement of the fixed shaft 14 can drive the push rod 21 to move towards the axis of the top rod 1, so that the inclined surface of the push rod 21 contacts the blocking shaft 19. At this time, under the weight of the extension rod 20 and the blocking shaft 19, the blocking shaft 19 will slide down, connecting the handrail 3 and the connecting pipe 18. After the connection, the remaining compressed gas will enter the connecting pipe 18 and flow upward through the connecting pipe 18 to push out the lifting shaft 24. When the lifting shaft 24 is pushed out, it will drive the moving frame 25 and the sliding frame 26 to move upward, and then drive the protective cover 28 to rotate through the connecting piece 27, thereby opening the protective cover 28. During the rotation of the protective cover 28, by setting a brush 32 inside the protective cover 28, the brush 32 can be moved by the protective cover 28 to wipe the lenses at both ends of the laser measuring instrument 33, so as to avoid dust remaining on the lenses of the laser measuring instrument 33 and affecting the measurement. Then, the laser measuring instrument 33 is used for measurement. After the measurement is completed, the fixed shaft 14 is moved back halfway, so that the positioning shaft 16 is away from the positioning hole 17. At this time, the return spring 6, which is in a compressed state, can push the pusher 4 downward in the air chamber 5 under the action of the elastic force, so that the bottom rod 2 is pushed upward relative to the top rod 1, and the ground rod 10 is retracted into the bottom rod 2. Then, the gas in the handrail 3 and the connecting pipe 18 is drawn into the air chamber 5. Finally, the fixed shaft 14 is pushed back completely. At this time, the fixed shaft 14 will drive the push rod 21 to move in the opposite direction. The extension rod 20 is pushed up through the inclined surface of the push rod 21, blocking the connecting pipe 18 and the handrail 3. And because the connecting pipe The air inside pipe 18 is evacuated, and the pressure inside pipe 18 returns to normal. At this time, the support component 30, which is in a stretched state, can pull down the movable frame 25, thereby causing the protective cover 28 to move in the opposite direction and close on the mounting base 29. As the top of the locking rod 8 moves down, it compresses the air in the locking chamber 7 located below the disc at the top of the locking rod 8. At this time, the handrail 3 separates from the locking chamber 7, and the locking chamber 7 is directly connected to the outside world. The pressure returns to normal, and the compressed air inside the locking rod 8 pushes the disc at the top of the locking rod 8 upward to reset it, causing the locking block 9 and gear 13 to separate and unlock the base plate 12.
