Description

Technical Field

[0001] This utility model relates to the field of distance measurement technology, specifically a device for measuring distances with large terrain elevation differences. Background Technology

[0002] Topographic elevation difference measurement is a common measurement method aimed at determining the height difference between two different locations, such as in building design, road and bridge construction, etc. By measuring the height difference, it is possible to ensure that these engineering projects comply with relevant regulations and standards during construction, thereby guaranteeing their safety and stability. During measurement, specialized measuring devices, tools and techniques are used to measure the height difference at different locations, allowing people to better understand the changes in topography. Existing topographic elevation difference measurement devices have poor stability in complex weather conditions in the field, and existing support legs are complicated to operate and have a large weight, making them inflexible in use. Therefore, a topographic elevation difference measurement device is needed.

[0003] Existing terrain elevation difference and large distance measurement devices cannot effectively improve the stability of the measurement work and the flexibility of the device adjustment support during operation. Therefore, there is an urgent need for a terrain elevation difference and large distance measurement device. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a terrain elevation difference measurement device to solve the problem that existing terrain elevation difference measurement devices cannot effectively improve the stability of the measurement work and cannot improve the flexibility of the device adjustment support.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a terrain elevation difference and large distance measuring device, comprising a measuring instrument body, a base installed at the lower end of the measuring instrument body, an inner top spring installed at the inner end of the base, a latch installed at the front end of the inner top spring, a counterweight hook installed at the lower end of the base, a carbon fiber support foot installed at the lower end of the base, a rotating hole opened at the upper end of the carbon fiber support foot, a limiting hole opened on the inner side of the carbon fiber support foot, a connecting block installed at the inner end of the limiting hole, an oblique limiting channel opened at the rear end of the connecting block, an oblique rod pressing block installed at the inner end of the oblique limiting channel, an upper top spring installed at the lower end of the oblique rod pressing block, and a carbon fiber extension foot installed at the lower end of the upper top spring.

[0006] Preferably, the latch is telescopically connected to the base via an inner top spring, and the inner end of the measuring instrument body is an open-hole type.

[0007] Preferably, the main body of the measuring instrument is engaged with the base by a bolt, and the counterweight hook is threadedly connected to the base.

[0008] Preferably, the carbon fiber legs form a rotating structure with the base through rotating holes, and the carbon fiber legs are distributed in a ring array around the central axis of the base.

[0009] Preferably, the connecting block forms a sliding structure with the carbon fiber extension foot through the inclined rod pressing block, and the inclined rod pressing block forms a telescopic structure with the carbon fiber extension foot through the upper top spring.

[0010] Preferably, the connecting block is engaged with the carbon fiber support foot via a diagonal bar pressing block, and the carbon fiber extension foot forms a telescopic structure with the carbon fiber support foot via the connecting block.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model uses a measuring instrument body, a base, an inner top spring, a latch, and a counterweight hook to place the measuring instrument body on the base. The force of the inner top spring causes the latch to move outward inside the base until it engages with the measuring instrument body, thereby fixing the installation position of the measuring instrument body. In complex outdoor weather conditions, stones or bricks can be added to the counterweight hook using a net or similar device, making the overall device more stable and preventing it from tipping over or shifting, thus improving the stability of the device's measurement work.

[0013] This invention utilizes a measuring instrument body, carbon fiber legs, limiting holes, connecting blocks, inclined limiting channels, inclined bar pressing blocks, upper springs, and carbon fiber extension legs. The inclined bar pressing blocks are pressed vertically downwards onto the carbon fiber extension legs, causing the connecting blocks to move inwards through the inclined limiting channels and the inclined bar pressing blocks until they no longer contact the carbon fiber legs. Then, the movement of each carbon fiber extension leg on the carbon fiber legs can be adjusted to a suitable position according to the terrain, allowing the three carbon fiber extension legs to horizontally support the base regardless of the complex terrain. The upper spring force causes the inclined bar pressing blocks to move outwards simultaneously until they engage with the inner limiting holes of the carbon fiber legs. The carbon fiber material makes the device lightweight, easy to operate, and improves the flexibility of adjustment and support. Attached Figure Description

The latch 4 forms a telescopic structure with the base 2 through the inner top spring 3. The inner end of the measuring instrument body 1 is open-hole set. The measuring instrument body 1 is connected to the base 2 by the latch 4, and the counterweight hook 5 is threadedly connected to the base 2. The measuring instrument body 1 is placed on the base 2, and the latch 4 moves outward in the base 2 by the force of the inner top spring 3 until it engages with the measuring instrument body 1, thereby fixing the installation position of the measuring instrument body 1. In complex field weather conditions, stones or bricks can be added with a net or similar means to suspend the device on the counterweight hook 5, making the overall use of the device more stable and preventing it from falling or shifting, thus improving the stability of the device's measurement work.

[0022] Please see Figures 1-4A terrain elevation difference and distance measuring device includes a base 2 with carbon fiber support legs 6 mounted on its lower end. A rotating hole 7 is provided at the upper end of the carbon fiber support legs 6. A limiting hole 8 is provided inside the carbon fiber support legs 6, and a connecting block 9 is installed inside the limiting hole 8. An oblique limiting channel 10 is provided at the rear end of the connecting block 9, and an oblique rod pressing block 11 is installed inside the oblique limiting channel 10. An upper spring 12 is installed at the lower end of the oblique rod pressing block 11, and a carbon fiber extension leg 13 is installed at the lower end of the upper spring 12. The carbon fiber support legs 6 form a rotating structure with the base 2 through the rotating hole 7, and the carbon fiber support legs 6 are arranged in a circular array around the central axis of the base 2. The connecting block 9 forms a sliding structure with the oblique rod pressing block 11 and the carbon fiber extension leg 13, and the oblique rod pressing block 11 forms a telescopic structure with the carbon fiber extension leg 13 through the upper spring 12. The connecting block 9 is pressed by the oblique rod... Block 11 engages with carbon fiber support leg 6, and carbon fiber extension leg 13 forms a telescopic structure with carbon fiber support leg 6 through connecting block 9. Pressing the inclined bar pressing block 11 vertically downward on the carbon fiber extension leg 13 causes the connecting block 9 to move inward simultaneously through the inclined limiting channel 10 and the inclined bar pressing block 11 until it no longer contacts the carbon fiber support leg 6. Then, the movement of each carbon fiber extension leg 13 on the carbon fiber support leg 6 can be adjusted to a suitable position according to the terrain, so that the three carbon fiber extension legs 13 can horizontally support the base 2 according to the complex terrain. The force of the upper spring 12 causes the inclined bar pressing block 11 to drive the connecting block 9 to move outward simultaneously until it engages with the inner end limiting hole 8 of the carbon fiber support leg 6. The carbon fiber material makes the device lightweight, easy to operate, and improves the flexibility of device adjustment and support.

[0023] Working principle: In use, first press the inclined bar pressing block 11 vertically downwards on the carbon fiber extension foot 13, so that the connecting block 9 moves inwards simultaneously with the inclined bar pressing block 11 through the inclined limiting channel 10 until it no longer contacts the carbon fiber support foot 6. Then, adjust the movement of each carbon fiber extension foot 13 on the carbon fiber support foot 6 to a suitable position according to the terrain, so that the three carbon fiber extension feet 13 can horizontally support the base 2 according to the complex terrain. The force of the upper spring 12 causes the inclined bar pressing block 11 to drive the connecting block 9 to move outwards simultaneously until it engages with the inner end limiting hole 8 of the carbon fiber support foot 6. The carbon fiber material makes the whole device lightweight. The device is quantified, easy to operate, and improves the flexibility of adjusting the support. Then, the main body 1 of the measuring instrument is placed on the base 2, and the force of the inner top spring 3 causes the bolt 4 to move outward in the base 2 until it engages with the main body 1 of the measuring instrument, thereby fixing the installation position of the main body 1 of the measuring instrument. In complex outdoor weather conditions, stones or bricks can be added to the counterweight hook 5 through a net or similar means to make the overall use of the device more stable and prevent it from falling over or shifting, thus improving the stability of the device's measurement work. This completes the use of the device. The contents not described in detail in this manual are existing technologies known to those skilled in the art.
