Description

Technical Field

[0001] This utility model relates to the field of surveying tools, specifically a benchmark for architectural surveying. Background Technology

[0002] Architectural surveying markers (also known as surveying marker poles) are basic tools used in engineering surveying for marking points, orientation, and alignment. They are generally 2-5 meter aluminum alloy / fiberglass round poles with red and white or red and yellow alternating segment markings (each segment 0.5-1 meter). When in use, they are inserted into the ground as temporary control points to assist the total station ordnance operator in positioning during topographic mapping.

[0003] Most existing architectural surveying benchmarks are assembled from multiple standard sections using a threaded structure. The convenient assembly and disassembly of the threaded structure makes them easy to carry and use. However, the threaded joints of the disassembled standard sections are exposed to the outside, making them highly susceptible to collisions with external objects during transfer and transportation, which can damage the threaded joints and affect subsequent docking and use. Based on this, a new type of architectural surveying benchmark is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a benchmark for architectural surveying in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a marker pole for architectural surveying, comprising a marker pole section, wherein quick-connect components are provided at the upper and lower ends of the marker pole section, and the quick-connect components are used for connecting and fixing two marker pole sections;

[0006] The quick-release assembly includes a fixing screw sleeve, a fixing storage sleeve, an I-shaped guide frame, a polygonal guide rod, a second limiting block, a stud, and a spring;

[0007] The fixing screw sleeve is press-fitted and fixed to the bottom inner side of the marker section, the fixing storage sleeve is press-fitted and fixed to the top inner side of the marker section, and the I-shaped guide frame is fixed to the bottom end of the fixing storage sleeve;

[0008] The stud is housed inside the fixed storage sleeve. The polygonal guide rod is fixed to the bottom of the stud and passes through the I-shaped guide frame. The polygonal guide rod is slidably connected to the I-shaped guide frame. The second limiting block is fixed to the outside of the polygonal guide rod and distributed inside the I-shaped guide frame. The spring is sleeved on the outside of the polygonal guide rod and distributed between the top of the second limiting block and the top of the inner wall of the I-shaped guide frame. It is used to provide downward pushing force to the second limiting block, thereby achieving the stability of the stud housed inside the fixed storage sleeve.

[0009] The stud protrudes from the outside of the fixed storage sleeve and is threadedly connected to the fixed sleeve on another marker section to achieve the assembly and fixation of the two marker sections.

[0010] As a further embodiment of this utility model: the quick-installation assembly also includes a cross-shaped fixing member, a telescopic rod, a first limiting block, a magnetic block, and an iron block;

[0011] The cross-shaped fixing member is fixed to the top of the fixing screw sleeve, the telescopic rod passes through the middle of the cross-shaped fixing member and is slidably connected to the cross-shaped fixing member, and the first limiting block and the magnetic block are respectively fixed to the upper and lower ends of the telescopic rod;

[0012] The iron block is embedded in the top of the stud;

[0013] When the first limiting block is attached to the top of the cross-shaped fixing member, the magnetic block is close to the bottom of the fixing screw sleeve to perform an adsorption operation on the iron block, thereby enabling the stud to protrude from the top of the fixing storage sleeve and enter the interior of the fixing screw sleeve.

[0014] As a further improvement of this utility model: the top of the stud has a smooth surface, and the height of the smooth surface of the stud is less than the height from the bottom of the magnetic block to the bottom of the fixing sleeve.

[0015] As a further improvement of this utility model: the bottom end of the polygonal guide rod protrudes to the bottom of the I-shaped guide frame and is connected to a third limiting block, the height of the third limiting block to the bottom of the I-shaped guide frame being less than the maximum contraction stroke of the spring.

[0016] As a further improvement of this utility model, the height of the fixing sleeve is greater than the sum of the heights of the stud and the magnetic block.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] The quick-release assembly allows for easy assembly and disassembly of the benchmark section. During daily transfers and transport, the studs are completely stored inside the fixed storage sleeve, meaning the quick-release assembly does not protrude from the outside of the benchmark section. Compared to the traditional benchmark threaded connectors that are exposed to the outside, this effectively avoids the problem of subsequent assembly failure due to damage caused by collisions between the threaded connectors and external objects.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 In this embodiment of the utility model, a marker for architectural surveying includes a marker section 1, and quick-connect assembly 2 is provided at the upper and lower ends of the marker section 1. The quick-connect assembly 2 is used to connect and fix two marker sections 1.

[0026] The quick-installation component 2 includes a fixing screw sleeve 201, a fixing storage sleeve 206, an I-shaped guide frame 207, a polygonal guide rod 209, a second limiting block 210, a stud 208, and a spring 212;

[0027] The fixing screw sleeve 201 is press-fitted and fixed to the bottom inner side of the pole section 1, the fixing storage sleeve 206 is press-fitted and fixed to the top inner side of the pole section 1, and the I-shaped guide frame 207 is fixed to the bottom end of the fixing storage sleeve 206.

[0028] The stud 208 is housed inside the fixed storage sleeve 206. The polygonal guide rod 209 is fixed to the bottom of the stud 208 and passes through the I-shaped guide frame 207. The polygonal guide rod 209 is slidably connected to the I-shaped guide frame 207. The second limiting block 210 is fixed to the outside of the polygonal guide rod 209 and distributed inside the I-shaped guide frame 207. The spring 212 is sleeved on the outside of the polygonal guide rod 209 and distributed between the top of the second limiting block 210 and the top of the inner wall of the I-shaped guide frame 207. It is used to provide a downward pushing force to the second limiting block 210, thereby stabilizing the stud 208 housed inside the fixed storage sleeve 206.

[0029] The stud 208 protrudes from the outside of the fixed storage sleeve 206 and is threadedly connected to the fixed screw sleeve 201 on the other pole section 1 to realize the assembly and fixation of the two pole sections 1;

[0030] The quick-installation component 2 also includes a cross-shaped fixing piece 202, a telescopic rod 203, a first limiting block 204, a magnetic block 205, and an iron block 213;

[0031] The cross-shaped fastener 202 is fixed to the top of the fixing screw sleeve 201, the telescopic rod 203 passes through the middle of the cross-shaped fastener 202 and is slidably connected to the cross-shaped fastener 202, and the first limiting block 204 and the magnetic block 205 are respectively fixed to the upper and lower ends of the telescopic rod 203.

[0032] Iron block 213 is embedded in the top of stud 208;

[0033] When the first limiting block 204 is attached to the top of the cross fastener 202, the magnetic block 205 is close to the bottom of the fixing screw sleeve 201 to perform an adsorption operation on the iron block 213, thereby realizing that the stud 208 protrudes from the top of the fixing storage sleeve 206 and enters the interior of the fixing screw sleeve 201.

[0034] The top of the stud 208 has a smooth surface, and the height of the smooth surface of the stud 208 is less than the height from the bottom of the magnetic block 205 to the bottom of the fixing sleeve 201.

[0035] In this embodiment, it should be noted that: except for the magnetic block 205 and the iron block 213, the other parts of the quick-release assembly 2 are made of aluminum alloy and cannot be attracted and fixed by the magnetic block 205.

[0036] Multiple marker sections 1 can be assembled into a longer marker. However, during daily transfer and carrying, the multiple marker sections 1 are disassembled. At this time, the stud 208 is completely stored inside the fixed storage sleeve 206. That is, the quick-release component 2 does not protrude from the outside of the marker section 1. Compared with the traditional marker threaded connector exposed to the outside, this effectively avoids the problem of subsequent assembly failure due to collision damage between the threaded connector and external objects.

[0037] When it is necessary to assemble the benchmark section 1, the assembly principle is as follows:

[0038] Take two sections of the marker section 1, tilt the fixed storage sleeve 206 on one section of the marker section 1 upwards, and tilt the fixed screw sleeve 201 on the other section of the marker section 1 downwards (the magnetic block 205 slides down under its own weight and approaches the bottom of the fixed screw sleeve 201). Then, bring the two sections of the marker section 1 closer together. Finally, the bottom of the fixed screw sleeve 201 is in contact with the top of the fixed storage sleeve 206 (that is, the two sections of the marker section 1 are in contact). At this time, the magnetic block 205 generates an attraction force on the iron block 213. This attraction force causes the iron block 213, the stud 208, the polygonal guide rod 209, and the second limiting block 210 to move upwards as a whole. The spring 212 is further compressed and contracted (it should be noted that the spring 212 has a small elastic force and is mainly used to ensure the stability of the stud 208 in its storage state. It will not hinder the stud 208 from being attracted and moved upwards).

[0039] The stud 208 moves upward so that its smooth surface is inserted into the fixed threaded sleeve 201. At this time, the top of the stud 208 is not yet fully attached to the magnetic block 205. Then, any standard section 1 is rotated, causing the stud 208 to rotate relative to the fixed threaded sleeve 201, thus aligning the outer thread of the stud 208 with the thread groove of the fixed threaded sleeve 201. At the same time, under the attraction of the magnetic block 205, the outer thread of the stud 208 can be connected to the thread groove of the fixed threaded sleeve 201 (at this time, the magnetic block 205 is attached to the top of the stud 208). After that, continue to rotate any standard section 1 to fully tighten the stud 208 and the fixed threaded sleeve 201 (at this time, the magnetic block 205, the telescopic rod 203, and the first limit block 204 are lifted and moved upward as a whole), thus completing the connection and fixation of the two standard sections 1. The operation is simple.

[0040] Please refer to this carefully. Figures 2-4 The bottom end of the polygonal guide rod 209 protrudes to the bottom of the I-shaped guide frame 207 and is connected to a third limiting block 211. The height of the third limiting block 211 to the bottom of the I-shaped guide frame 207 is less than the maximum contraction stroke of the spring 212.

[0041] In this embodiment: when the stud 208 and the fixing sleeve 201 are fully tightened, the third limiting block 211 is in close contact with the bottom of the I-shaped guide 207 to realize the movement limit of the stud 208. At the same time, the spring 212 is not fully compressed, so as to avoid stress fatigue caused by frequent full contraction of the spring 212.

[0042] Please refer to this carefully. Figures 2-4 The height of the fixing sleeve 201 is greater than the sum of the heights of the stud 208 and the magnetic block 205.

[0043] In this embodiment: This structure allows the fixing sleeve 201 to accommodate the stud 208 and the magnetic block 205 as a whole, ensuring that the stud 208 and the fixing sleeve 201 are completely tightened.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
