Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of level instrument fixing brackets, and in particular to an adjustable fixing bracket for a level instrument. Background Technology
[0002] In fields such as engineering surveying, building construction, and topographic mapping, the level instrument is a core device for accurately measuring elevation differences. Its measurement accuracy is closely related to the performance of its auxiliary fixed support. The level instrument fixed support needs to provide a stable foundation for the equipment, while also meeting the requirements of rapid deployment, accurate horizontal calibration, and flexible angle adjustment, so as to adapt to complex field terrain and efficient measurement operation scenarios.
[0003] Existing fixed supports suffer from low deployment efficiency. Most existing support structures employ a split, manually adjustable design, requiring the extension and retraction of support legs to be done individually by turning knobs or fixing them step-by-step with bolts. This lack of guiding and elastic structures to aid rapid deployment results in lengthy initial setup times during field operations. Furthermore, the lack of precise guidance and fine-tuning mechanisms during adjustment allows for only coarse height adjustments, making it difficult to adapt to complex terrain with significant undulations. To overcome these disadvantages, this invention provides an adjustable fixed support for leveling instruments. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an adjustable fixing bracket for a level.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable fixed bracket for a level, comprising a support base, a turntable rotatably connected to the top of the support base, a sliding groove formed at the top of the turntable, a slider slidably connected to the sliding groove, a horizontal angle adjustment component provided on the sliding groove, a plurality of first rotating seats fixedly connected to the side of the support base, a first rotating block rotatably connected to the first rotating seat, a telescopic chamber fixedly connected to one side of the first rotating block, a telescopic plate slidably connected to the telescopic chamber, a fixed component provided on the telescopic chamber, a quick telescopic component provided inside the telescopic chamber, a limiting telescopic rod fixedly connected to one side of the telescopic plate, a second rotating seat fixedly connected to the output end of the limiting telescopic rod, a fine-tuning component provided on one side of the telescopic plate and located on the side of the limiting telescopic rod, a second rotating block rotatably connected to one side of the second rotating seat, and a support component provided on one side of the second rotating block.
[0006] Furthermore, the horizontal angle adjustment component includes a first threaded rod rotatably connected to the slide groove, a first threaded hole on one side of the slider, the first threaded hole and the first threaded rod being threadedly connected, a first knob rotatably connected to one side of the turntable, one end of the first threaded rod passing through the slide groove and being fixedly connected to one end of the first knob, a transmission rod rotatably connected inside the support base, one end of the transmission rod passing through the support base and being fixedly connected to one side of the turntable, a worm gear fixedly connected to the transmission rod, a worm rotatably connected inside the support base, the worm and the worm wheel being meshed together, a second knob rotatably connected to the bottom end of the support base, one end of the worm passing through the support base and being fixedly connected to one end of the second knob.
[0007] Furthermore, the fixing component includes a plurality of first pin holes opened on one side of the telescopic chamber, and a plurality of second pin holes opened on one side of the telescopic plate, with pins provided on the first and second pin holes.
[0008] Furthermore, the quick-release assembly includes several sliding rods fixedly connected to the interior of the telescopic chamber, springs fixedly connected to the interior of the telescopic chamber and around the sliding rods, several sliding holes opened on one side of the telescopic plate, the sliding holes and the sliding rod assembly being slidably connected, and a handle fixedly connected to one side of the telescopic plate.
[0009] Furthermore, the fine-tuning component includes a handle that is rotatably connected to one side of the telescopic plate and to the side of the limiting telescopic rod. One end of the handle has a second threaded hole, and a second threaded rod is threadedly connected to the second threaded hole. One end of the second threaded rod is fixedly connected to one side of the second rotating seat.
[0010] Furthermore, the support assembly includes a support plate fixedly connected to one side of the second rotating block, a plurality of anti-slip strips fixedly connected to one side of the support plate, and a plurality of fixing holes formed on one side of the support plate.
[0011] The beneficial effects of this utility model are:
[0012] When using this utility model,
[0013] 1. Through the synergistic action of the quick-release and fine-tuning components, the sliding rod inside the telescopic chamber of the quick-release component guides the sliding of the telescopic plate. The spring pushes the telescopic plate to pop out quickly, and with the handle, the support structure can be quickly deployed, greatly shortening the initial erection time. After the support is initially deployed, the handle of the fine-tuning component drives the second threaded rod to rotate. Combined with the guidance of the limit telescopic rod, the position of the second rotating seat can be finely adjusted, thereby accurately adjusting the height of the support according to different terrains, ensuring that the support as a whole remains horizontal and meeting the level requirements of the level instrument for the foundation.
[0014] 2. By rotating the second knob in the horizontal angle adjustment component, the worm gear and worm wheel can be engaged to rotate the turntable and adjust the horizontal angle of the level. Then, rotating the first knob will rotate the first threaded rod and make the slider slide along the groove to fine-tune the lateral position of the level. Through dual adjustment, the level can be accurately aligned with the measurement target. Attached Figure Description

[0023] As shown in the figure, the horizontal angle adjustment assembly includes a first threaded rod 5 rotatably connected to the slide groove 3, a first threaded hole 6 on one side of the slider 4, and a threaded connection between the first threaded hole 6 and the first threaded rod 5. A first knob 7 is rotatably connected to one side of the turntable 2. One end of the first threaded rod 5 passes through the slide groove 3 and is fixedly connected to one end of the first knob 7. A transmission rod 8 is rotatably connected inside the support base 1. One end of the transmission rod 8 passes through the support base 1 and is fixedly connected to one side of the turntable 2. A worm gear 9 is fixedly connected to the transmission rod 8. A worm 10 is rotatably connected inside the support base 1, and the worm 10 and the worm gear 9 are meshed together. A second knob 11 is rotatably connected to the bottom end of the support base 1. One end of the worm 10 passes through the support base 1 and is fixedly connected to one end of the second knob 11. This assembly is used to adjust the horizontal angle and horizontal displacement of the level on the slider 4.
[0024] As shown in the figure, the fixing component includes a plurality of first pin holes 19 on one side of the telescopic chamber 14 and a plurality of second pin holes 20 on one side of the telescopic plate 15. The first pin holes 19 and the second pin holes 20 are provided with pins 21 for quickly fixing the telescopic chamber 14 and the telescopic plate 15 together.
[0025] As shown in the figure, the quick-release assembly includes several sliding rods 16 fixedly connected to the inside of the telescopic chamber 14. Springs 18 are fixedly connected inside the telescopic chamber 14 and around the sliding rods 16. Several sliding holes 17 are opened on one side of the telescopic plate 15. The sliding holes 17 are slidably connected to the sliding rod 16 assembly. A handle 31 is fixedly connected to one side of the telescopic plate 15 for quickly releasing the support of the device.
[0026] As shown in the figure, the fine-tuning component includes a handle 22 that is rotatably connected to one side of the telescopic plate 15 and to one side of the limiting telescopic rod 25. One end of the handle 22 has a second threaded hole 23, and a second threaded rod 24 is threadedly connected to the second threaded hole 23. One end of the second threaded rod 24 is fixedly connected to one side of the second rotating seat 26 for finely adjusting the support position of the device.
[0027] As shown in the figure, the support assembly includes a support plate 28 fixedly connected to one side of the second rotating block 27. Several anti-slip strips 30 are fixedly connected to one side of the support plate 28, and several fixing holes 29 are opened on one side of the support plate 28 for supporting the device.
[0028] Working principle: During use, first check if the entire device is intact. After inspection, the measuring personnel move the device to the required measurement position, then pull out the pins 21 from the first pin hole 19 and the second pin hole 20. The spring 18 then undergoes elastic deformation, pushing the telescopic plate 15 to slide within the telescopic chamber 14, pushing the telescopic plate 15 out of the telescopic chamber 14. When the telescopic plate 15 extends to the appropriate position, insert the pins 21 into the first pin hole 19 on one side of the telescopic chamber 14 and the second pin hole 20 on the side of the telescopic plate 15 to initially fix the device. After initial fixing, if the support is not level due to terrain undulations, rotate the handle 22 on one side of the telescopic plate 15. The handle 22 drives the second threaded hole 23 at one end to rotate. Since the second threaded hole 23 is threadedly connected to the second threaded rod 24, and one end of the second threaded rod 24 is fixed to the second rotating seat 26, which is constrained by the limiting telescopic rod 25, rotating the handle 22 will drive the second threaded rod 24 to move axially, thereby driving the second rotating seat 25 to rotate. 6. Make fine adjustments up and down. Once the desired position is reached, stop turning the handle 22. Then, the support plate 28 contacts the ground to support the device. If the terrain is soft or prone to displacement, ground nails can be driven through the fixing holes 29 on the support plate 28 and driven into the ground to rigidly fix the support plate 28 to the ground, further preventing the support from shaking. Then, install the level on the slider 4 and start the level to perform measurements. When horizontal angle adjustment is needed during the measurement process, turn the second knob 11. The second knob 11 drives the worm gear 10 to rotate. Since the worm gear 10 and worm wheel 9 are meshed, the rotation of the worm gear 10 will drive the worm wheel 9 and the transmission rod 8 to rotate synchronously. One end of the transmission rod 8 is fixed to the turntable 2. Therefore, the turntable 2 rotates smoothly with the transmission rod 8, thereby driving the level on the turntable 2 to adjust the horizontal measurement angle. When horizontal movement is needed during the measurement process, turn the first knob 7. The first knob 7 drives the first threaded rod 5 on the slide groove 3 to rotate, thereby causing the slider 4 to slide on the slide groove 3, thereby driving the level to move and adjust horizontally.
