Description

Technical Field

[0001] This utility model relates to the field of building surveying equipment technology, and in particular to a building surveying equipment that can prevent tilting. Background Technology

[0002] Building surveying equipment consists of tools and instruments used in building engineering to measure and control various parameters. These devices play an important role in building design, construction, and maintenance. They can improve the accuracy and efficiency of measurements, helping engineers and construction workers to better complete building projects.

[0003] A search revealed a Chinese patent with authorization number CN220540788U, which discloses an anti-tilt building measurement device. The device includes a bracket, base, fixing strip, and screw. A driving block, via a connecting block, causes the mounting bracket on one side of the fixing strip to change angle. This solves the problems of existing devices easily tilting during measurement, lack of convenient horizontal adjustment, inability to prevent tilting, and inconvenient height adjustment, making it unsuitable for different measurement scenarios and affecting the accuracy and practicality of the measurement operation. However, it cannot expand the support area during use, and may be unstable when the building measurement device is in a high position. Furthermore, since the device is not directly fixed to the ground, it is prone to tipping over upon impact. Therefore, these problems need to be addressed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tilt-resistant building measurement device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tilt-resistant building surveying device includes a base with four sliding plates horizontally connected inside. The base also includes a sliding mechanism for the four sliding plates. A first support rod is rotatably connected to the center of the top of the base. A second support rod is positioned above the first support rod, and a mounting plate is fixedly connected to the top of the second support rod. A connecting rod is fixedly connected to the top of the mounting plate, and a measuring instrument body is mounted on the top of the connecting rod. A protective mechanism is provided at the bottom of the base. By using a second connecting sleeve, the first support rod can be rotated during use, simultaneously rotating the second connecting sleeve and causing the four sliding plates to slide away from each other, thus supporting the device. Simultaneously, the insertion rod slides downwards, allowing the insertion rod at the bottom of the device to insert into the ground, making the device more stable during use.

[0007] Preferably, the base has two first horizontal grooves and two second horizontal grooves inside. The two first horizontal grooves are arranged at the same horizontal level, and the two second horizontal grooves are also arranged horizontally. The two bases are respectively disposed on the top of the two second horizontal grooves. The two first horizontal grooves are perpendicular to the two second horizontal grooves. The four sliding plates are respectively disposed inside the two first horizontal grooves and the two second horizontal grooves. The curved surface of the base has four vertical grooves that are vertically formed. The four vertical grooves are respectively connected to the two first horizontal grooves and the two second horizontal grooves. The four sliding plates are fixedly connected to a support leg at one of their opposite ends. The four support legs are slidably connected to the four vertical grooves to restrict the sliding of the four sliding plates.

[0008] Furthermore, the sliding mechanism includes four racks, each fixedly connected to one end of one of the four sliding plates, which are close to each other. The four racks are staggered. A vertical circular groove is formed at the center of the base, and a second connecting sleeve is rotatably connected inside the groove. A gear ring is fitted onto the outer surface of the second connecting sleeve, and all four racks mesh with the gear ring. The bottom end of the first support rod is fixedly connected to the top of the second connecting sleeve, and a first connecting sleeve is fitted onto the top of the first support rod. The second support rod is vertically slidably fitted inside the first support rod, and the first connecting sleeve is fitted onto the surface of the second support rod. The first connecting sleeve cooperates with the first and second support rods to rotate the first support rod and simultaneously rotate the second connecting sleeve, thereby driving the four sliding plates to rotate.

[0009] Preferably, the protective mechanism includes a plug rod, which is vertically slidably connected to the center of the base. The second connecting sleeve has a thread inside, and the plug rod is slidably fitted inside the second connecting sleeve. The surface of the plug rod mates with the thread. A fixing ring is fitted into the bottom of the circular groove. Two limiting blocks are fixedly connected to the inner wall of the fixing ring. Two limiting grooves are vertically formed on the surface of the plug rod, and the two limiting blocks are respectively set inside the two limiting grooves. The bottom of the plug rod is tapered, so that when the second connecting sleeve rotates, the plug rod will slide up and down under the restriction of the two limiting blocks.

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

[0011] 1. During use, rotating the first support rod will also drive the second connecting sleeve to rotate. With the gear ring in place, the four racks and four slide plates will slide away from each other, thereby unfolding the four support legs, thus increasing the support area of ​​the device and making the device more stable during use.

[0012] 2. While the first support rod and the second connecting sleeve are rotating, the thread on the temporal part of the second connecting sleeve, and the restriction of the two limiting blocks, will cause the insertion rod to slide vertically downward, which will facilitate the insertion of the insertion rod into the soil and improve the stability of the device during use.

The base 1 also has a sliding mechanism for the four sliding plates 5. A first support rod 2 is rotatably connected to the center of the top of the base 1. A second support rod 3 is mounted on the top of the first support rod 2. A mounting plate 31 is fixedly connected to the top of the second support rod 3. A connecting rod 32 is fixedly connected to the top of the mounting plate 31. A measuring instrument body 33 is mounted on the top of the connecting rod 32. A protective mechanism is provided at the bottom of the base 1. Through the setting of a second connecting sleeve 4, the first support rod 2 can be rotated during use, and the second connecting sleeve 4 will also rotate, causing the four sliding plates 5 to slide away from each other, thus facilitating support for the device. Simultaneously, the insertion rod 6 will slide downwards, allowing the insertion rod 6 at the bottom of the device to insert into the ground, making the device more stable during use.

[0021] In this utility model, the base 1 has two first horizontal grooves 11 and two second horizontal grooves 12 inside. The two first horizontal grooves 11 are set at the same horizontal level, and the two second horizontal grooves 12 are also set at the same horizontal level. The two bases 1 are respectively set on the top of the two second horizontal grooves 12. The two first horizontal grooves 11 are perpendicular to the two second horizontal grooves 12. The four sliding plates 5 are respectively set inside the two first horizontal grooves 11 and the two second horizontal grooves 12. The surface of the base 1 has four vertical grooves 13 vertically opened on the arc surface. The four vertical grooves 13 are respectively connected to the two first horizontal grooves 11 and the two second horizontal grooves 12. The four sliding plates 5 are fixedly connected to the opposite ends of each other with support legs 51. The four support legs 51 are slidably connected to the four vertical grooves 13 to restrict the sliding of the four sliding plates 5.

[0022] In this utility model, the sliding mechanism includes four racks 52, which are fixedly connected to four sliding plates 5 at one end close to each other. The four racks 52 are staggered. A circular groove 14 is vertically opened at the center of the base 1. A second connecting sleeve 4 is rotatably connected inside the circular groove 14. A gear ring 42 is sleeved on the outer surface of the second connecting sleeve 4. All four racks 52 mesh with the gear ring 42. The bottom end of the first support rod 2 is fixedly connected to the top of the second connecting sleeve 4. A first connecting sleeve 21 is sleeved on the top of the first support rod 2. The second support rod 3 is vertically slidably sleeved inside the first support rod 2. The first connecting sleeve 21 is sleeved on the surface of the second support rod 3. The first connecting sleeve 21 cooperates with the first support rod 2 and the second support rod 3 to rotate the first support rod 2 and the second connecting sleeve 4, thereby driving the four sliding plates 5 to rotate.

[0023] In this utility model, the protective mechanism includes a rod 6, which is vertically slidably connected to the center of the base 1. The second connecting sleeve 4 has a thread 41 inside, and the rod 6 is slidably fitted inside the second connecting sleeve 4. The surface of the rod 6 is engaged with the thread 41. A fixing ring 15 is fitted into the bottom of the circular groove 14. Two limiting blocks 16 are fixedly connected to the inner wall of the fixing ring 15. Two limiting grooves 61 are vertically opened on the surface of the rod 6, and the two limiting blocks 16 are respectively set inside the two limiting grooves 61. The bottom of the rod 6 is tapered, so that when the second connecting sleeve 4 rotates, the rod 6 will slide up and down under the restriction of the two limiting blocks 16.

[0024] Working principle: In actual use, the second connecting sleeve 4 allows the first support rod 2 to rotate, which in turn rotates the second connecting sleeve 4, causing the four sliding plates 5 to slide away from each other, thus facilitating support for the device. Simultaneously, the insertion rod 6 slides downwards, allowing it to insert into the ground at the bottom of the device, making it more stable during use. When in use, rotating the first connecting sleeve 21 releases the restriction between the first support rod 2 and the second support rod 3. Then, the second support rod 3 can be pulled upwards from inside the first support rod 2, allowing the device to... The height of the device is adjusted during use, and then the first support rod 2 and the second support rod 3 are locked by rotating the first connecting sleeve 21. This structure is also existing technology. Then, the base 1 is placed on the ground. By rotating the first support rod 2, the second connecting sleeve 4 will also rotate. At this time, through the thread 41 provided inside the second connecting sleeve 4, the insertion rod 6 will slide downward under the restriction of the two limit blocks 16 while the second connecting sleeve 4 is rotating. Since the bottom of the insertion rod 6 is tapered, the insertion rod 6 will be inserted into the soil, thus making the device more stable during use.
