Description

Technical Field

[0001] The utility model relates to the technical field of real estate surveying and mapping, in particular to an independent benchmark frame used for real estate surveying and mapping. Background Art

[0002] A surveying pole is a type of benchmark that is usually used to mark or locate specific points on the ground surface. It is often used in surveying, geographic information systems, and land surveying. These poles are usually made of plastic or wood, and are usually brightly colored for easy identification in the field. Surveying poles are usually used to measure and mark locations, compile maps, or perform other related work. There are at least the following disadvantages in the use of existing surveying poles: 1. During the use of existing surveying poles, personnel often hold them in their hands. Affected by the length of time spent surveying, the length of time personnel hold the pole in their hands will also increase. After holding the pole for a long time, surveyors will not only have sore hands, but the pole will also easily tilt, thus affecting accuracy. Therefore, we have introduced an independent pole stand for real estate surveying. Utility Model Content

[0003] The main purpose of the utility model is to provide an independent benchmark frame for real estate surveying and mapping, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A benchmark independent frame for real estate surveying and mapping includes a connecting sleeve, the connecting sleeve is an internal hollow structure, a benchmark body is inserted and movably connected in the connecting sleeve, a No. 1 limit bolt is threadedly connected to the upper part of the outer surface of the connecting sleeve, and three supporting mechanisms are fixedly connected to the lower part of the outer surface of the connecting sleeve, and the three supporting mechanisms are distributed in a triangular shape with equal distances.

[0006] Preferably, the supporting mechanism includes a connecting piece, a slot is opened at the lower end of the connecting piece, an adjusting rod is movably connected in the slot, a No. 2 limiting bolt is threadedly connected to the adjusting rod, an extended support rod is inserted and movably connected to the lower end of the adjusting rod, the lower end of the extended support rod is a narrow lower and wide upper structure, a No. 3 limiting bolt is threadedly connected to the adjusting rod, and the No. 3 limiting bolt is located below the No. 2 limiting bolt.

[0007] Preferably, a connecting shaft is fixedly connected to the inner wall of the connecting member, and an arc-shaped sliding groove is formed on the connecting member.

[0008] Preferably, the adjusting rod is movably connected to the connecting shaft through insertion, and the second limiting bolt slides in the arc-shaped sliding groove.

[0009] Preferably, a telescopic sleeve is fixedly connected to the upper end of the connecting sleeve.

[0010] Preferably, the telescopic sleeve is in contact with the outer surface of the pole body.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. By setting a connecting sleeve, and installing three supporting mechanisms on the outer surface of the supporting mechanism, the adjusting rod on the angle-adjusting supporting mechanism is used to adjust the supporting angle of the adjusting rod and the extended supporting rod. During the adjustment process, the No. 2 limit bolt will slide on the arc-shaped slide groove. By tightening the No. 2 limit bolt, the No. 2 limit bolt squeezes the connecting piece and fixes the adjusted adjusting rod. Then, the remaining two supporting mechanisms are operated in this way. Under the support of the three supporting mechanisms, the benchmark body can be supported and fixed, so that the benchmark body can be vertical without human support, which reduces the work intensity of personnel and improves stability.

[0013] 2. By arranging a telescopic sleeve on the connecting sleeve, after the connecting sleeve and the benchmark body are inserted, the telescopic sleeve will hold the benchmark body tightly, thereby preventing dust from entering the connecting sleeve during use and affecting the removal of the connecting sleeve from the benchmark body.
