Description

Technical Field

[0001] The utility model relates to the field of surveying and mapping benchmarks, in particular to a telescopic surveying and mapping benchmark. Background Art

[0002] A surveying pole refers to a tool used to measure and calibrate the height, length or angle of the ground or a building, and is commonly used in municipal surveying. For example, the utility model patent with the authorization announcement number CN114215831B proposes a surveying pole for municipal engineering topographic surveying, which includes an upper connecting rod, a lower connecting rod and a fixed sleeve. The upper connecting rod and the lower connecting rod are magnetically connected, and the fixed sleeve is mounted at the connection between the upper connecting rod and the lower connecting rod. An upper slide groove is provided on the bottom outer wall of the upper connecting rod, and a lower slide groove corresponding to the upper slide groove is provided on the top outer wall of the lower connecting rod. An upper slider and a lower slider are provided on the inner wall of the fixed sleeve. The lower slider is located below the upper slider, and the upper slider matches the upper slide groove, and the lower slider matches the lower slide groove. An upper rotating groove is provided on the circumferential direction of the inner wall of the upper slide groove.

[0003] However, most of the existing surveying and mapping poles are extended by screw thread, which is inconvenient to operate and store, and only relies on the tip of the bottom to be inserted into the ground for fixing, which has insufficient grip and poor stability. Therefore, it needs to be improved. Utility Model Content

[0004] The utility model aims to provide a telescopic surveying and mapping benchmark, which solves the problem that the existing surveying and mapping benchmarks are mostly extended by threaded screwing, which is inconvenient to operate and inconvenient to store. At the same time, it solves the problem that the bottom tip is only inserted into the ground for fixation, resulting in insufficient grip and poor stability.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a telescopic surveying and mapping benchmark, comprising a benchmark body and a benchmark plug, a plurality of connecting frames being welded between the benchmark body and the benchmark plug, a benchmark telescopic body being slidably connected inside the benchmark body, a bayonet being slidably connected inside the benchmark telescopic body, the bayonet being slidably connected to the benchmark body, a spring being arranged inside the benchmark telescopic body, a guide sleeve being fixedly connected to the outer upper part of the benchmark body, a push pin being slidably connected to the inner side of the guide sleeve, one end of the push pin being in contact with the bayonet, and a button being fixedly connected to the other end of the push pin.

[0006] Preferably, one end of the spring is fixedly connected to the bayonet, and the other end of the spring is fixedly connected to the inner surface of the telescopic body of the pole. By setting the spring, elastic force can be applied to the bayonet.

[0007] Preferably, a protective cover is fixedly connected to one end of the button close to the main body of the pole, and the protective cover is fixedly connected to the main body of the pole. The provision of the protective cover can protect the button and the push button and prevent them from being lost.

[0008] Preferably, the side wall of the benchmark plug is slidably connected to two pins, and the front section of the pin body of each pin is fixedly connected to a limit ring, and a knob is rotatably connected between the benchmark body and the benchmark plug, and an adjustment rod is fixedly connected to the bottom of the knob, and an adjustment sleeve is threadedly connected to the outside of the rod body of the adjustment rod, and a push block is fixedly connected to the bottom of the adjustment sleeve, and the push block contacts the pin. The displacement generated by the relative threaded movement between the adjustment sleeve and the adjustment rod can push the push block to move, so that the push block applies thrust to the pin.

[0009] Preferably, the outer side of the adjustment sleeve is fixedly connected with a guide rod, the inner wall of the reference rod plug is fixedly connected with a guide groove, and the guide groove is slidably connected with the guide rod. The setting of the guide rod and the guide groove has a guiding effect on the axial movement of the adjustment sleeve on the adjustment rod.

[0010] Preferably, the circumferential surface of the knob is provided with anti-slip grooves, and the knob is in contact with the connecting frame. The arrangement of the knob facilitates the rotation of the adjusting rod.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model provides a slidable benchmark telescopic body on the inner side of the benchmark body, and a plurality of spring-retracted bayonet pins are provided inside the benchmark telescopic body. The bayonet pins are inserted into the side wall of the benchmark body under the action of the springs. In this way, the telescopic adjustment between the benchmark telescopic body and the benchmark body can be completed by controlling the engagement and disengagement of the bayonet pins and the benchmark body through pushing the push pins on the outer side of the benchmark body. Compared with the traditional surveying and mapping benchmark using threaded extension, the utility model is more convenient.

[0013] 2. The utility model divides the main part of the surveying and mapping benchmark into a benchmark body and a benchmark plug, and connects the two with a plurality of connecting frames. In addition, an adjusting rod is arranged in the benchmark plug to be rotated by a knob, and the adjusting sleeve produces relative displacement due to the relative threaded movement between the adjusting sleeve and the adjusting rod. Then, the push block at the end of the adjusting sleeve pushes the two pins on the side wall of the benchmark plug outward and is inserted into the ground together with the benchmark plug, thereby increasing the grip with the ground and improving the stability during use.
