Description

Technical Field

[0001] This utility model relates to the field of measuring benchmark technology, and in particular to a multifunctional measuring benchmark for use in on-site supervision. Background Technology

[0002] A surveying pole is a surveying device, a measuring tool painted with alternating red and white paint. It is used for setting lines in the surveying process, mainly to indicate measurement points. In conjunction with a surveying instrument, the position of the pole is used to pinpoint specific locations. By setting multiple points and recording the corresponding information, the location to be measured can be depicted. Surveying poles are an indispensable measurement and control accessory in the initial surveying work of various engineering construction projects. According to their material, they can be divided into wooden surveying poles and aluminum alloy surveying poles. According to their function and purpose, they can be divided into aiming poles, indicating poles, and reference poles, etc.

[0003] According to the announcement number CN218238852U, an engineering surveying aiming rod is proposed. When using this surveying rod, the bottom of the stable base is placed on a hard ground, and then the first counterweight ring and the second counterweight ring are respectively inserted into the first placement groove and the second placement groove by the pull ring. The first counterweight ring and the second counterweight ring can increase the stability of the surveying rod itself assembled inside the stable base, so as to achieve the effect of placing and fixing it in different environments, making it multi-functional and improving the practicality of the surveying rod itself.

[0004] Currently, measuring poles are usually made of metal, with a stable base at the bottom to enhance stability and improve their resistance to tipping when affected by wind. However, due to the use of high-density metal materials, they are inconvenient to carry, especially in situations where frequent relocation is required. Workers have to expend a lot of physical strength to move them, which reduces work efficiency. In addition, the heavy base also limits the possibility of single-person operation, often requiring multiple people to work together to move and set up the equipment, which increases labor costs.

[0005] Therefore, there is an urgent need to provide a multi-functional measuring benchmark for on-site supervision to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a multi-functional measuring rod for on-site supervision.

[0007] To solve the above-mentioned technical problems, the present invention provides a multi-functional measuring pole for on-site supervision, including a pole body, a painted pointed corner fixed at the bottom end of the pole body, and a telescopic pole slidably installed inside the pole body; The top of the telescopic marker is fixed with a limiting seat that is slidably connected to the inside of the marker body. The top of the marker body is threaded with a limiting sleeve. One side of the limiting sleeve is threaded with a first screw that passes through and extends into the inside of the telescopic marker. The bottom of the measuring pole body is provided with an extension mechanism to enhance the stability of the measuring pole under various complex working environments and stress conditions. The top of the extension mechanism is provided with a rotating mechanism to facilitate the movement and erection of the equipment by a single person.

[0008] Using the above technical solution, the marker pole body with painted sharp corners is inserted into the ground or other foundation surface at a predetermined position. If it is necessary to adjust the measurement height, the telescopic marker pole is held and pulled up or down, so that it slides into the appropriate position inside the marker pole body. Then, the first screw is tightened, and the telescopic marker pole is fixed in that position by the limiting screw sleeve and the limiting seat.

[0009] The present invention is further configured such that: the extension mechanism includes a pointed sleeve that is fitted and installed on the outside of the marker body and the painted pointed corner, and the bottom end of the pointed sleeve is fixed with a mounting plate shell.

[0010] With the above technical solution, when encountering complex terrain or needing to enhance stability, the painted sharp corner is inserted into the sharp corner sleeve, and the stability of the marker body is improved by installing the disc shell.

[0011] The present invention is further configured such that: three arc-shaped extension rods are rotatably mounted inside the mounting plate housing, the three arc-shaped extension rods are evenly spaced along the circumferential direction, and the top of each of the three arc-shaped extension rods is fixed with a mounting gear.

[0012] The above technical solution uses a gear to drive the arc-shaped extension rod to unfold, thereby increasing the support area of ​​the mounting plate. When the arc-shaped extension rod retracts inward, the volume of the mounting plate can be reduced, making it easier to transport.

[0013] The present invention is further configured such that: a base is fixed to the bottom of the mounting plate, the base is tightly fitted with three arc-shaped extension rods, and a mounting ring is fixed to the top of the mounting plate.

[0014] Through the above technical solution, the base of the disk housing is combined with the arc-shaped extension rod, so that the bottom of the mounting disk housing is not a hollow structure.

[0015] The present invention is further configured such that: the rotating mechanism includes a rotating ring rotatably mounted outside the mounting ring, and a rotating handle is fixed to the top end of the rotating ring.

[0016] The above technical solution allows the rotating ring to be driven by hand through a rotating handle, rotating it through the mounting ring.

[0017] The present invention is further configured such that: a mounting toothed ring is fixed at the bottom end of the rotating ring, the outside of the mounting toothed ring meshes with the outside of the mounting gear, and a limiting top ring is attached to the top end of the mounting ring.

[0018] With the above technical solution, the mounting ring drives the mounting gear ring to rotate, the limiting top ring limits the top of the mounting ring, and the mounting gear ring drives the three mounting gears to rotate.

[0019] The present invention is further configured such that: a second screw is threadedly fixed at the top end of the limiting top ring, one end of which passes through and extends into the interior of the mounting ring; and a rubber ring that fits against the rotating ring is fixed at the bottom end of the limiting top ring.

[0020] The above technical solution uses a second screw to thread-press and fix the limiting top ring, so that the rubber ring and the top of the rotating ring are tightly fitted, preventing the rotating ring from rotating arbitrarily.

[0021] The beneficial effects of this utility model are as follows: 1. This utility model, by providing an extension mechanism, allows three arc-shaped extension rods to quickly and effectively expand the support area when needed, enhancing the stability of the measuring rod in various complex working environments and under stress conditions. It performs particularly well when bearing eccentric loads, and greatly reduces the overall weight, making it easier for staff to carry and transfer, thus significantly improving work efficiency. 2. This utility model, by incorporating a rotating mechanism, can drive three arc-shaped extension rods to unfold and retract, better adapting to various complex working environments and stress conditions, reducing the overall size, facilitating the movement and setup of the equipment by a single person, and further improving work efficiency and user experience.

[0025] Please see Figures 1-4 A multi-functional measuring pole for on-site supervision includes a pole body 1, with a painted pointed corner 2 fixed at the bottom end of the pole body 1. A telescopic pole 3 is slidably installed inside the pole body 1. A limiting seat 4 is fixed at the top end of the telescopic pole 3 and slidably connected to the inside of the pole body 1. A limiting sleeve 5 is threadedly fixed at the top end of the pole body 1. A first screw 6, with one end penetrating and extending into the inside of the telescopic pole 3, is threadedly fixed on one side of the limiting sleeve 5. An extension mechanism 7 is provided on the outside of the bottom end of the pole body 1 to enhance the stability of the measuring pole under various complex working environments and stress conditions. The extension mechanism 7 includes a pointed corner sleeve 701 fitted and installed on the outside of the pole body 1 and the painted pointed corner 2. A mounting plate shell 702 is fixed at the bottom end of the pointed corner sleeve 701. Three arc-shaped extension rods 703 are rotatably installed inside the mounting plate shell 702. The three arc-shaped extension rods 703 are evenly spaced along the circumference. A mounting gear 704 is fixed at the top end of each of the three arc-shaped extension rods 703. A base plate 705 is fixed to the bottom of the housing 702. The base plate 705 fits tightly with three arc-shaped extension rods 703. An installation ring 706 is fixed to the top of the mounting housing 702. The marker body 1 with painted corners 2 is inserted into the ground or other foundation surface at the predetermined position. If the measurement height needs to be adjusted, the telescopic marker 3 is held and pulled up or down to slide into the appropriate position inside the marker body 1. Then, the first screw 6 is tightened, and the telescopic marker 3 is fixed in this position by the limiting screw sleeve 5 and the limiting seat 4. When encountering complex terrain or needing to enhance stability, the painted corners 2 are inserted into the corner sleeve 701. The stability of the marker body 1 is improved by installing the housing 702. The arc-shaped extension rods 703 are extended by the installation gear 704. The support area of ​​the mounting housing 702 is increased by the arc-shaped extension rods 703. After the arc-shaped extension rods 703 are retracted inward, the volume of the mounting housing 702 can be reduced, making it easier to transport.

[0026] like Figure 3 and Figure 4 As shown, the top of the extension mechanism 7 is provided with a rotating mechanism 8 to facilitate the movement and setup of the equipment by a single person. The rotating mechanism 8 includes a rotating ring 801 rotatably mounted on the outside of the mounting ring 706. A rotating handle 802 is fixed to the top of the rotating ring 801, and a mounting gear ring 803 is fixed to the bottom of the rotating ring 801. The outside of the mounting gear ring 803 meshes with the outside of the mounting gear 704. A limiting top ring 804 is attached to the top of the mounting ring 706. The top of the limiting top ring 804 is threaded with one end that passes through and extends into the mounting ring 706. The second screw 805 of the part is used to fix the bottom end of the limiting top ring 804 to a rubber ring 806 that fits against the rotating ring 801. By hand, the rotating ring 801 is driven to rotate by rotating the handle 802 through the mounting ring 706. The mounting ring 706 drives the mounting gear ring 803 to rotate accordingly. The mounting gear ring 803 drives the three mounting gears 704 to rotate accordingly. The limiting top ring 804 is fixed by the thread compression of the second screw 805, so that the rubber ring 806 fits tightly against the top of the rotating ring 801, so that the rotating ring 801 will not rotate arbitrarily.

[0027] In use, the marker body 1 with the painted pointed corner 2 is inserted into the ground or other foundation surface at a predetermined position. If the measurement height needs to be adjusted, the telescopic marker 3 is grasped and pulled up or down to slide into the appropriate position inside the marker body 1. Then, the first screw 6 is tightened, and the telescopic marker 3 is fixed in this position by the limiting screw sleeve 5 and the limiting seat 4. When encountering complex terrain or needing to enhance stability, the painted pointed corner 2 is inserted into the pointed corner sleeve 701. The stability of the marker body 1 is improved by the mounting disc shell 702. The rotating ring 801 is driven by rotating the handle 802 by hand, which is connected to the mounting ring 7. The device rotates at position 6, causing the mounting ring 706 to drive the mounting gear ring 803 to rotate accordingly. The mounting gear ring 803 then drives the three mounting gears 704 to rotate. The second screw 805 secures the limiting top ring 804 with threaded compression, ensuring that the rubber ring 806 fits tightly against the top of the rotating ring 801, preventing the rotating ring 801 from rotating arbitrarily. The mounting gears 704 then drive the arc-shaped extension rod 703 to unfold, increasing the support area of ​​the mounting disc shell 702. Similarly, by retracting the arc-shaped extension rod 703 inward, the volume of the mounting disc shell 702 can be reduced, facilitating transportation.
