Description

Technical Field

[0001] This invention relates to the field of building surveying technology, specifically to a field surveying device for building design with adjustable functions. Background Technology

[0002] Whether in building construction or interior architectural design, surveying equipment is needed to measure and lay out lines on site. The surveying equipment mainly consists of two parts: a laser line projector and a support frame. During use, the laser line projector emits a laser beam, which is then passed through a prism light guiding system to form a laser surface to project horizontal and vertical laser lines, ultimately achieving the purpose of measurement.

[0003] Patent application CN202421546273.1 discloses an adjustable on-site surveying device for architectural design, relating to the field of architectural design technology. This adjustable on-site surveying device includes a mounting block, a steering mechanism, and a telescopic mechanism. Multiple sets of annularly distributed hinged blocks are fixedly mounted on the bottom of the mounting block. The steering mechanism is located on the top of the mounting block and includes a rotating rod, a circular support plate, a sliding cavity, an internally threaded block, a connecting rod, and an arc-shaped plate. The top of the mounting block is rotatably connected to one end of the rotating rod, and the other end of the rotating rod is fixedly connected to the bottom of the circular support plate. The inner wall of the sliding cavity is slidably connected to the outer wall of the internally threaded block. A connecting rod is fixedly mounted on one side of the internally threaded block, and one end of the connecting rod extends to the outside of the mounting block where the arc-shaped plate is fixedly mounted. Without the need for a moving device, the surveying instrument can be quickly adjusted in any direction (360 degrees). It is simple and easy to operate, and its surveying range is increased.

[0004] The existing equipment lacks an effective leveling function, making it difficult to quickly and accurately level the surveying instrument. This makes it difficult for operators to adjust the instrument's posture according to the site terrain, which seriously affects the accuracy, reliability, and consistency of the survey data, and reduces the overall efficiency and quality of on-site surveying work for architectural design. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a field survey device for architectural design with adjustable functions, thereby solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a field surveying device for architectural design with adjustable function, comprising a first hollow ring, a connecting frame fixedly connected to the outer wall of the bottom of the first hollow ring, a rotating plate fixedly connected to the outer wall of the connecting frame, a telescopic rod rotatably connected to the inner wall of the bottom of the rotating plate via a bearing, a central mechanism rotatably connected to the inner wall of the first hollow ring via a bearing, a placement component fixedly connected to the top of the central mechanism, a surveying instrument fixedly connected to the top of the placement component, and a bottom component fixedly connected to the bottom of the central mechanism;

[0007] The central organization includes:

[0008] A deflection ring is provided, with first hollow columns fixedly connected to both its front and rear sides. The outer walls of the two first hollow columns are rotatably connected to the first hollow ring via bearings. Friction rings are fixedly connected to the inner walls of the first hollow columns.

By setting a central mechanism, gravity can be used to quickly perform preliminary leveling of the placement frame, which helps to reduce the time of manual coarse adjustment and improve the leveling efficiency. At the same time, the mechanism, through the cooperation of the deflection ring and the second hollow column, provides sufficient space for the surveying instrument to move, making the gravity leveling process more sensitive and smooth, thus providing a foundation for subsequent fine leveling.

A second elastic component is fixedly connected to the end of the first circular plate near the second hollow ring. The first and second limiting plates are used to limit the range of motion of the second pressure plate. By setting the locking component, the deflection ring can be locked to prevent accidental rotation during measurement, thereby maintaining the stability of the central mechanism's posture and improving the overall reliability of the device.

The top of the placement frame is fixedly connected to the surveying instrument. The adjustment knob is used to fine-tune the level of the disc. By setting up the placement component, after initial leveling, fine-tuning can be performed, further enhancing the horizontal accuracy of the surveying instrument. Through the cooperation of the adjustment knob and the disc, combined with the observation of the level tube, the operator can quickly and intuitively adjust the disc to a horizontal state, improving leveling efficiency and accuracy.

A first groove is formed on the outer wall of the sleeve, and a locking hole is formed on the inner side of the sleeve. By setting the bottom component, the second hollow column can be quickly locked, preventing subsequent operations or the placement of the surveying instrument from interfering with the leveled state and ensuring the stability of the leveling effect. Simultaneously, the counterweight in the bottom component enhances the overall stability of the device, and the central column and locking rod can lock the relevant components after leveling, preventing the leveling state from failing due to accidental contact or external force, thus improving the reliability of on-site surveying.

[0016] According to the above technical solution, the inner wall of the sleeve is rotatably connected to a central column via a bearing. A groove is provided at the top of the central column.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0042] Example 1: See Figures 1-7 The present invention provides a technical solution: a field surveying device for architectural design with adjustable function, comprising a first hollow ring 1, a connecting frame 101 fixedly connected to the outer wall of the bottom of the first hollow ring 1, a rotating plate 102 fixedly connected to the outer wall of the connecting frame 101, a telescopic rod 103 rotatably connected to the inner wall of the bottom of the rotating plate 102 via a bearing, a central mechanism 2 rotatably connected to the inner wall of the first hollow ring 1 via a bearing, a placement component 22 fixedly connected to the top of the central mechanism 2, a surveying instrument 3 fixedly connected to the top of the placement component 22, and a bottom component 23 fixedly connected to the bottom of the central mechanism 2; a first slider 105 fixedly connected to the outer wall of the first hollow ring 1, a square groove 104 opened at the top of the first hollow ring 1, a locking component 21 fixedly connected to the inner wall of the square groove 104, a through hole 106 opened on the outer side of the square groove 104, and an adjusting component 11 rotatably connected to the outer wall of the first hollow ring 1 via a bearing, wherein the rotation of the adjusting component 11 is used to change the state of the locking component 21.

[0043] The adjustment assembly 11 includes a first rotating ring 111. The inner wall of the first rotating ring 111 is rotatably connected to the first hollow ring 1 via a bearing. The inner wall of the first rotating ring 111 has a first arc-shaped groove 112 and a second arc-shaped groove 113. The inner wall of the first arc-shaped groove 112 is movably connected to the first slider 105. The first arc-shaped groove 112 and the first slider 105 are used to limit the movement angle of the adjustment assembly 11.

[0044] The central mechanism 2 includes: a deflection ring 201, with first hollow columns 202 fixedly connected to both the front and rear sides of the deflection ring 201. The outer walls of the two first hollow columns 202 are rotatably connected to the first hollow ring 201 via bearings. A friction ring 203 is fixedly connected to the inner wall of the first hollow column 202. A first connecting column 204 is fixedly connected to the inner wall of the deflection ring 201. A friction column 205 is fixedly connected to the outer wall of the first connecting column 204. A second hollow column 206 is provided on the inner wall of the deflection ring 201. A first connecting ring 207 is fixedly connected to the outer wall of the second hollow column 206. The inner wall of the first connecting ring 207 is rotatably connected to the first connecting column 204 via bearings. The top of the second hollow column 206 is fixedly connected to the placement assembly 22. The deflection ring 201 and the second hollow column 206 provide space for the movement of the surveying instrument 3 on top of the placement assembly 22. A first elastic... Component 208 has a first elastic component 208 with a first pressure plate 209 fixedly connected to one end away from the second hollow column 206. The bottom of the first pressure plate 209 is fixedly connected to a second connecting column 2010. There are two sets of the first elastic component 208 and the first pressure plate 209. The two sets of first pressure plates 209 are used to clamp the friction column 205, thereby locking the deflection angle of the second hollow column 206. When the device needs to be placed, it is supported on the ground or workbench by the telescopic rod 103 and the rotating plate 102. The deflection ring 201 in the central mechanism 2 and the second hollow column 206 allow the placement component 22 and its surveying instrument 3 to deflect freely in two directions. Under the action of gravity, the center of gravity of the surveying instrument 3 and the placement component 22 will automatically sink, causing the second hollow column 206 and the deflection ring 201 to swing relative to the first hollow ring 1 until the surveying instrument 3 reaches an approximately horizontal state.

[0045] Example 2: Please refer to Figures 8-15Based on Embodiment 1, the present invention provides a technical solution: the locking component 21 includes a second hollow ring 211, a connecting plate 212 fixedly connected to the outer wall of the second hollow ring 211, a first circular plate 213 fixedly connected to the end of the connecting plate 212 away from the second hollow ring 211, a first limiting plate 214 fixedly connected to the outer wall of the first circular plate 213, a second limiting plate 215 fixedly connected to the outer wall of the second hollow ring 211, a first circular plate 213 fixedly connected to the outer wall of the first circular plate 213, a second pressure plate 219 movably connected to the outer wall of the first limiting plate 214, a second pressure plate 219 movably connected to the outer wall of the second limiting plate 215, and a second elastic component 216 fixedly connected to the end of the first circular plate 213 near the second hollow ring 211, wherein the first limiting plate 214... The second limiting plate 215 is used to limit the range of motion of the second pressure plate 219. The inner wall of the second hollow ring 211 is movably connected to a force-bearing column 2110. The end of the force-bearing column 2110 near the first circular plate 213 is fixedly connected to a third hollow column 217. The inner wall of the third hollow column 217 is fixedly connected to the second elastic component 216. The outer wall of the third hollow column 217 is rotatably connected to a connecting rod 218 through a bearing. The end of the connecting rod 218 away from the third hollow column 217 is rotatably connected to the second pressure plate 219 through a bearing. When the adjusting component 11 rotates, the position of the force-bearing column 2110 changes. When it is necessary to lock the angle of the deflection ring 201, the first rotating ring 111 is rotated to disengage the force-bearing column 2110 from the second arc-shaped groove 113. At this time, the inner wall of the first rotating ring 111 squeezes the force-bearing column 2110, pushing the force-bearing column 2110 and its third hollow column 217 to move inward; the third hollow column 217 drives the second pressure plate 219 to move outward through the connecting rod 218, thereby making the second pressure plate 219 press tightly against the friction ring 203, and relying on friction to achieve a stable lock on the deflection ring 201.

[0046] The placement assembly 22 includes a second circular plate 221, the bottom of which is fixedly connected to a second hollow column 206. An adjustment knob 222 is fixedly connected to the top of a second hollow ring 211. A disc 223 is fixedly connected to the top of the adjustment knob 222. A placement frame 224 is fixedly connected to the top of the disc 223. A level tube 225 is fixedly connected to the top of the disc 223. The top of the placement frame 224 is fixedly connected to the surveying instrument 3. The adjustment knob 222 is used for fine-tuning the level of the disc 223. After completing the initial coarse adjustment and initial locking of gravity, the disc 223 is precisely leveled. The level tube 225 fixed on the top of the disc 223 is observed, and the tilt direction of the disc 223 is determined according to the position of the bubble in the level tube 225. Then, the adjustment knob 222 is manually rotated to cause the disc 223 to deflect at a small angle, thereby changing the horizontal attitude of the disc 223 and the placement frame 224 above it. After completing the precise leveling, the surveying instrument 3 is fixedly installed on the top of the placement frame 224.

[0047] The bottom assembly 23 includes a sleeve 231. The top of the sleeve 231 is fixedly connected to the second hollow column 206, and the bottom of the sleeve 231 is fixedly connected to a third connecting column 232. A counterweight 233 is fixedly connected to the bottom of the third connecting column 232. The outer wall of the sleeve 231 has a first groove 234, and the inner side of the sleeve 231 has a locking hole 235. The inner wall of the sleeve 231 is rotatably connected to a central column 236 via a bearing. The top of the central column 236 has a sliding groove 237. The inner wall of slide 237 is movably connected to the second connecting post 2010. A second slider 238 is fixedly connected to the outer wall of slide 237. The outer wall of the second slider 238 is movably connected to the first slot 234. A second rotating ring 239 is fixedly connected to the end of the second slider 238 away from the central post 236. A second slot 2310 is opened at the top of the second rotating ring 239. A second connecting ring 2311 is movably connected to the outer wall of the second rotating ring 239. The inner wall of the second connecting ring 2311 is fixedly connected to... The third slider 2312 has a locking rod 2313 fixedly connected to its bottom. The locking rod 2313 slides through the second slot 2310 and extends to the inner wall of the locking hole 235. The outer wall of the locking rod 2313 is movably connected to the locking hole 235. The rotation of the central column 236 is used to change the merging state of the first pressure plate 209. When it is necessary to lock the angle of the second hollow column 206, the second connecting ring 2311 is pulled upward first, so that the locking rod 2313 is pulled out from the locking hole 235, releasing the initial locking state of the bottom component. Then, the second connecting ring 2311 is rotated, which drives the second rotating ring 239 to rotate through the third slider 2312, thereby driving the central column 236 to rotate. The sliding groove 237 at the top of the central column 236 rotates accordingly, pushing the second connecting column 2010 to move towards the center, thereby driving the two sets of first pressure plates 209 to move closer to the middle, tightly clamping the friction column 205, and realizing a stable lock on the deflection angle of the second hollow column 206.
