Description

Technical Field

[0001] This utility model relates to the field of surveying device technology, and in particular to a surveying device that is easy to adjust the surveying height. Background Technology

[0002] In fields such as geological exploration, engineering construction, and topographic surveying, surveying devices are key tools for obtaining accurate geographic data. The ease and stability of their height adjustment directly affect surveying accuracy and work efficiency. Currently, the height of a surveying device is adjusted using three support frames, followed by fine-tuning using bolts on the device. However, if the height needs to be increased or decreased during the surveying process, and the required adjustment amount is too large, the height adjustment of the bolts on the surveying device is limited, necessitating the re-erecting of three sets of support frames, which affects work efficiency. Therefore, we propose a surveying device that facilitates height adjustment. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a surveying device that facilitates the adjustment of surveying height.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a surveying device that facilitates adjustment of surveying height, comprising a mounting platform, a surveying device mounted on the top of the mounting platform, three supporting leveling feet rotatably mounted on the outer wall of the mounting platform, a groove formed at the center of the mounting platform, a mounting plate fixedly mounted in the groove, a threaded screw fixedly connected to the bottom of the mounting plate, a connecting rod slidably mounted in the groove, a base fixedly connected to the top of the connecting rod, a synchronization ring fixedly connected to the bottom of the connecting rod, and a height adjustment component mounted above the synchronization ring.

[0005] Preferably, the inner wall of the groove is provided with four limiting grooves, and the included angle between two adjacent limiting grooves is ninety degrees.

[0006] Preferably, four connecting rods are provided, and each of the four connecting rods has a limiting rod that is adapted to the limiting groove fixed to its outer side. The four limiting rods are slidably connected in the four limiting grooves respectively, and the synchronization ring is fixedly connected by the four connecting rods.

[0007] Preferably, the outer wall of the mounting plate is fixedly connected to four fixing rods, and the four fixing rods are respectively fixedly connected to the inner wall of the groove between two adjacent limiting grooves.

[0008] Preferably, the height adjustment assembly includes a bolt, a timing sleeve, and extension rods. The bolt is threaded onto the outer wall of the threaded screw, and the bottom of the bolt is rotatably connected to a circular timing sleeve. Four extension rods arranged in a cross shape are fixed to the outer wall of the timing sleeve.

[0009] Preferably, the height adjustment assembly further includes an inner groove, a sliding rod, a collar, and an anti-rotation hole. The two opposing connecting rods each have an inner groove on their sides that are close to each other. A sliding rod is slidably installed in each of the two inner grooves. A collar is fixedly connected between the two sliding rods. The inner wall of the collar has an anti-rotation hole that is adapted to the outer wall of the bolt. The collar is slidably fitted onto the outer wall of the bolt through the anti-rotation hole.

[0010] The beneficial effects of this utility model are:

[0011] 1. In use, this utility model uses the threaded connection between the bolt and the threaded screw in the height adjustment component. Rotating the bolt can drive the synchronous sleeve and extension rod to move, thereby realizing the height adjustment of the surveying device through the connecting rod and the base. Compared with the problem of limited fine adjustment stroke of traditional bolts, this structure can realize a wide range of height adjustment by means of threaded transmission. There is no need to rebuild the three support leveling feet, which solves the drawback of having to disassemble and reinstall the support frame when the adjustment is too large, and greatly improves work efficiency.

[0012] When using this invention, adjustment is simple: just pull the collar to make the sliding rod slide in the inner groove, and after disengaging from the bolt, rotate the bolt to adjust the height. Once the height is set, loosen the collar so that it passes through the anti-rotation hole and engages the bolt to lock it in place. The entire process does not require disassembling any parts, and the operation steps are simple. During the adjustment process, the limit rod slides in the limit groove, and the synchronization ring ensures that the four connecting rods move synchronously, preventing the mounting platform and surveying device from tilting and maintaining the initial leveling state without the need for secondary leveling.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-5 As shown, a surveying device that facilitates adjusting the surveying height is disclosed, comprising a mounting platform 1, a surveying device 2 mounted on the top of the mounting platform 1, three supporting leveling feet 3 rotatably mounted on the outer wall of the mounting platform 1, a groove 4 formed at the center of the mounting platform 1, a mounting plate 5 fixedly mounted in the groove 4, a threaded screw 11 fixedly connected to the bottom of the mounting plate 5, a connecting rod 9 slidably mounted in the groove 4, a base 8 fixedly connected to the top of the connecting rod 9, a synchronization ring 13 fixedly connected to the bottom of the connecting rod 9, and a height adjustment component mounted above the synchronization ring 13.

[0023] The inner wall of the groove 4 is provided with four limiting grooves 7, and the included angle between two adjacent limiting grooves 7 is ninety degrees.

[0024] There are four connecting rods 9. Each of the four connecting rods 9 has a limiting rod 10 that is adapted to the limiting groove 7 fixed to its outer side. The four limiting rods 10 are slidably connected in the four limiting grooves 7 respectively. The synchronous ring 13 is fixedly connected through the four connecting rods 9.

[0025] Four fixing rods 6 are fixed to the outer wall of the mounting plate 5. The four fixing rods 6 are respectively fixed to the inner wall of the groove 4 between two adjacent limiting grooves 7.

[0026] The height adjustment assembly includes a bolt 14, a synchronous sleeve 15, and extension rods 19. The bolt 14 is threaded onto the outer wall of the threaded screw 11. The bottom of the bolt 14 is rotatably connected to a ring-shaped synchronous sleeve 15. Four extension rods 19 arranged in a cross shape are fixed to the outer wall of the synchronous sleeve 15. A synchronous ring 13 rigidly connects the four connecting rods 9 in the groove into a single unit, ensuring that the four connecting rods 9 in the groove rise and fall synchronously during height adjustment. This keeps the base 8 level and prevents the surveying device 2 from tilting due to uneven force. This synchronous design, combined with the force transmission of the extension rods 19, makes the height adjustment process smoother and reduces measurement errors caused by component movement, making it particularly suitable for high-precision surveying scenarios.

[0027] The height adjustment assembly also includes an inner groove 12, a sliding rod 16, a collar 17, and an anti-rotation hole 18. The two opposing connecting rods 9 each have an inner groove 12 on their sides closest to each other. A sliding rod 16 is slidably installed in each of the two inner grooves 12, and a collar 17 is fixedly connected between the two sliding rods 16. An anti-rotation hole 18, adapted to the outer wall of the bolt 14, is provided on the inner wall of the collar 17. The collar 17 slides onto the outer wall of the bolt 14 through the anti-rotation hole 18. The sliding fit between the limiting groove 7 and the limiting rod 10 restricts the rotational freedom of the connecting rod 9, ensuring that height adjustment is only performed in the vertical direction. This prevents the surveying device 2 from horizontally deflecting during adjustment and maintains initial leveling accuracy. The sliding rod 16 sliding in the inner groove 12 drives the collar 17 to move up and down. When the collar 17 engages with the bolt 14 through the anti-rotation hole 18, it can quickly lock the height, preventing the bolt 14 from shifting due to vibration. This double-limiting design enhances the device's anti-interference capability.

[0028] Working principle: In use, the mounting platform 1 is first supported by three leveling feet 3, and its initial height is determined. When the height of the surveying device 2 needs to be adjusted again during the surveying process, the collar 17 is pulled upward between the two inner grooves 12, causing the collar 17 to disengage from the bolt 14. Then, the bolt 14 is rotated. The bolt 14 is threadedly connected to the threaded screw 11, and during its rotation, it drives the synchronous sleeve 15 to slide on the outer wall of the threaded screw 11. The synchronous sleeve 15 is connected to the threaded screw 11 by four extension rods. 19 drives the base 8 at the top of the four connecting rods 9 to move synchronously, thereby adjusting the height of the surveying device 2 through the base 8. The limiting rods 10 on the outside of the four connecting rods 9 slide in the limiting grooves 7 respectively to prevent the synchronous ring 13 from rotating during height adjustment. When the height is determined, the collar 17 is loosened, and the two sliding rods 16 slide downward in the two inner grooves 12 until the collar 17 fits the bolt 14 through the anti-rotation hole 18 to prevent the bolt 14 from rotating and causing the height of the surveying device 2 to change.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
