Abstract
Description
Technical Field
[0001] This utility model relates to a marker, specifically a marker for surveying and setting out, and belongs to the field of engineering surveying technology. Background Technology
[0002] In engineering surveying, instruments are often used for mapping, and modern instruments often have marking and transmission functions, which brings certain convenience to surveying. During work, the positioning function of surveying instruments is particularly important; a good positioning device determines the speed and quality of the work. In the process of surveying and setting out, a total station is often used in conjunction with a prism rod for setting out, especially in building construction. When using a total station and prism rod to determine the points, setting the prism rod aside after the points are determined before taking out the positioning tools not only slows down the setting out speed but also fails to accurately mark the points.
[0003] Existing technology includes a prism rod positioning device that can be fixed at specific points, which greatly reduces the difficulty of setting points during construction layout, reduces errors by workers, eliminates the adverse effects of losing the fixed point, and improves the situation of wasting manpower and resources in on-site work. At the same time, the prism rod is easy to modify and convenient to carry; after each use, it only needs to be placed stably against a wall. However, this device uses positioning pins for marking, which requires manual stepping to achieve the marking and positioning, resulting in poor convenience. Furthermore, the positioning pins cannot be recycled, increasing costs. To address these issues, this paper provides a marking device for surveying and layout. Utility Model Content
[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a marker for surveying and setting out, which aims to improve the problems of time-consuming, labor-intensive, and costly existing technologies.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a marker for surveying and setting out, comprising a prism and prism rods, wherein a plurality of the prism rods are installed at the bottom end of the prism, and a marking mechanism is provided at the bottom end of any one of the prism rods, and a locking mechanism is provided on one side of the marking mechanism; the locking mechanism is connected to the marking mechanism.
[0006] Furthermore, the marking mechanism includes a frame, a middle frame is provided between the frames, a compression spring is fixedly installed at the top inside the frame, a convex plate is fixedly connected to the bottom end of the compression spring, and a marking positioning pin is fixedly connected to the bottom end of the convex plate by bolts.
[0007] Furthermore, openings are provided on both sides of the frame; a rectangular block is provided on the outer side of the frame; the convex plate passes through the openings and is fixedly connected to the rectangular block.
[0008] Furthermore, the locking mechanism includes an outer frame, an inner side of which is fitted with a tension spring, one end of which is fixedly connected to a pull rod, a sliding groove is formed on the surface of the outer frame, a slider is slidably connected in the sliding groove, the pull rod passes through the slider and is fixedly connected, the top of the pull rod is located outside the sliding groove, a handle is provided on the top of the pull rod, and a crossbar is fixedly installed on one side of the pull rod.
[0009] Furthermore, the opening slot is arranged opposite to the crossbar; the crossbar can be moved horizontally to seal the bottom of the middle frame or open the bottom of the middle frame.
[0010] Furthermore, a triangular pad is installed at the bottom of the marking mechanism. The triangular pad has an open structure. Fixed blocks are fixedly installed at both ends of the inner side of the triangular pad. Grooves are opened on both sides of the fixed blocks. A translation block is slidably connected inside the groove. A rod is fixedly connected to the surface of the translation block.
[0011] Furthermore, one end of each insertion rod is fixedly connected to a sleeve, and a locking knob is provided through the outer surface of the insertion rod. The locking knob passes through the insertion rod and the translation block in sequence and is screwed into the inside of the groove. The positioning pin passes through the sleeve.
[0012] This utility model has the following beneficial effects:
[0013] In this utility model, the marking mechanism and locking mechanism enable convenient positioning and marking during surveying and layout, preventing the inability to accurately locate the layout position when fixing points. At the same time, it solves the problem of needing to manually mark layout points in the prior art. The manual control handle drives the slider to move in the sliding groove, the slider drives the pull rod to move, the pull rod drives the crossbar to separate from the bottom of the middle frame, and the compression spring drives the marking positioning nail to be launched into the ground. The nail tip protrusion leaves a mark on the ground to complete the marking.
[0014] This invention allows the rectangular block to retract the marking and positioning nail into the interior of the middle frame. Then, the rebound force of the tension spring drives the crossbar to spring back to the bottom opening of the middle frame for limiting and blocking, thus completing the convenient device retrieval. The width of the sleeve can be adjusted to match the specifications of the marking and positioning nail, increasing the stability of the nail structure during marking. Attached Figure Description
