Description

Technical Field

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

[0002] Red and white markers (also known as red and white surveying markers) are the most commonly used visual positioning tools in surveying operations. Their core feature is the high-contrast red and white color scheme, which is characterized by "easy recognition and strong adaptability". They are designed to provide clear observation targets for equipment such as total stations, levels, and GPS, and are widely used in topographic surveying, engineering layout, construction positioning and other scenarios.

[0003] Common red and white marker poles on the market usually come in two types: a single continuous pole and a multi-section assembled pole. In the existing multi-section assembled pole, each section is independent after disassembly. Although this can reduce the space occupied, individual sections are prone to being lost after being separated, which affects the normal use of the marker pole. Utility Model Content

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

[0005] To achieve the above objectives, this utility model provides the following technical solution: a marker for architectural surveying, comprising multiple marker sections connected end to end, with adjacent marker sections being connected by a rigid connector and a flexible connector. The rigid connector includes a bolt joint and a nut joint, which are respectively located at the mating ends of two adjacent standard sections, and are connected by a threaded engagement. The flexible connector includes a connecting rope, the two ends of which are respectively connected to the top ends of two adjacent marker sections; and at least one end of the connecting rope is slidably connected to the corresponding marker section.

[0006] Preferably, the bolt joint includes a threaded portion and a bolt head, the bolt head being embedded at the top of the corresponding marker section.

[0007] Preferably, the connecting rope is slidably connected to one end of the marker section with a nut joint. A limit stop is also provided between the nut joint and the marker section. The limit stop is provided with a clearance hole for the connecting rope to pass through. One end of the connecting rope passes through the nut joint and the limit stop and extends into the receiving groove. A clamp is provided at the top of the connecting rope located in the receiving groove. The limit stop is used to prevent the clamp from disengaging from the receiving groove.

[0008] Preferably, the connecting rope is fixedly connected to one end of the marker section with a bolt joint. The bolt joint is provided with a through hole that passes through the screw and the bolt head. The through hole is arranged coaxially with the screw and is used for the connecting rope to pass through. The end of the bolt head away from the screw is provided with a receiving groove II. The receiving groove II is circular and arranged coaxially with the through hole. The end of the connecting rope that passes through the through hole is fixed with a clamp II. The shape of the clamp II is consistent with the receiving groove II.

[0009] Preferably, the connecting rope is made of nylon.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention allows for the disassembly of individual marker sections when not in use. After disassembly, the sections are connected by a connecting rope, which forms a flexible connection between adjacent sections. The sections can be folded together, significantly reducing the space required for marker storage and facilitating their carrying and storage. This design reduces the disarray of the sections and effectively prevents individual sections from falling or being lost. Attached Figure Description

[0013] 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.

[0014] like Figures 1 to 10 As shown, a surveying pole includes multiple pole sections 1 connected end to end, with adjacent pole sections 1 being connected by rigid and flexible connectors.

[0015] The rigid connector includes a bolt joint 21 and a nut joint 22, which are respectively disposed at the mating ends of two adjacent marker sections 1, and are connected by a threaded engagement. Specifically, the bolt joint 21 and the nut joint 22 are both embedded at the top of the corresponding marker section 1. Depending on the actual connection requirements, the connection strength between the bolt joint 21 or the nut joint 22 and the marker section 1 can be further strengthened by means of rivets or welding to prevent the bolt joint 21 or the nut joint 22 from loosening or falling off under normal use.

[0016] In one specific embodiment, the bolt joint 21 includes a threaded portion 201 and a bolt head 202, which are integrally formed, with a structure identical to that of existing bolts. The bolt head 202 is embedded at the top of the corresponding standard section 1. When riveting or welding is required for reinforcement, the bolt head 202 is preferentially further fixed to the standard section 1. The threaded portion 201 is coaxially arranged with the corresponding standard section 1 and located outside the top of the standard section 1. The nut joint 22 is embedded at the top of the corresponding standard section 1. The threaded hole of the nut joint 22 is coaxially arranged with the corresponding standard section 1, and the outer end face of the nut joint 22 is flush with or lower than the top face of the corresponding standard section 1. In addition, the length of the threaded portion 201 is the same as the thickness of the nut joint 22 to ensure that when the bolt joint 21 and the nut joint 22 are engaged, the top faces of the two corresponding standard sections 1 can form contact, ensuring the continuity and straightness of the connection between the two standard sections 1.

[0017] The flexible connector includes a connecting rope 31, with both ends of the connecting rope 31 connected to the top ends of two adjacent marker sections 1 respectively; and at least one end of the connecting rope 31 is slidably connected to the corresponding marker section 1, that is: both ends of the connecting rope 31 can be slidably engaged with the corresponding marker section 1; or one end of the connecting rope 31 can be fixedly connected to one corresponding marker section 1, and the other end of the connecting rope 31 can be slidably engaged with another corresponding marker section 1.

[0018] Preferably, the connecting rope 31 is slidably connected to one end of the marker section 1 with the nut connector 22. Specifically, a receiving groove 11 is provided inside the marker section 1 and on the inner side of the nut connector 22. A limiting baffle 23 is also provided between the nut connector 22 and the marker section 1. The limiting baffle 23 is provided with a clearance hole (not shown in the figure) for the connecting rope 31 to pass through. The receiving groove 11 is used to receive the connecting rope 31. One end of the connecting rope 31 passes through the threaded hole of the nut connector 22 and the clearance hole of the limiting baffle 23 and finally extends into the receiving groove 11. The top of the connecting rope 31 inside 11 is provided with a locking head 32. Both the locking head 32 and the receiving groove 11 are preferably designed as circular structures. The diameter of the locking head 32 is smaller than the diameter of the receiving groove 11 to ensure that the connecting rope 31 with the locking head 32 can slide smoothly in the receiving groove 11. The diameter of the locking head 32 is larger than the diameter of the clearance hole to ensure that the limiting baffle 23 can effectively prevent the locking head 32 from moving out of the receiving groove 11, and ensure that the connecting rope 31 will not fall out in the receiving groove 11.

[0019] Preferably, the connecting rope 31 is fixedly connected to one end of the marker section 1 with the bolt joint 21. Specifically, the bolt joint 21 is provided with a through hole 203 penetrating the screw portion 201 and the bolt head 202. The through hole 203 is coaxially arranged with the screw portion 201 and is used for the connecting rope 31 to pass through. The end of the bolt head 202 away from the screw portion 201 is provided with a receiving groove 204. The receiving groove 204 is preferably circular and coaxially arranged with the through hole 203. The end of the connecting rope 31 passing through the through hole 203 is fixed with a clamp 33. The shape of the clamp 33 is consistent with the receiving groove 204. In this way, after the bolt head 202 is fixed to the corresponding marker section 1, the clamp 33 is located in the receiving groove 204 and is restricted between the bolt head 202 and the marker section 1, thus achieving a fixed connection between the connecting rope 31 and the corresponding marker section 1.

[0020] In this embodiment, the connecting rope 31 is preferably made of nylon. Nylon rope has a smooth surface, is strong and wear-resistant, and has a certain degree of toughness, which is beneficial for the connecting rope 31 to slide within the receiving groove 11. The diameter of the connecting rope 31 is determined according to the design diameter of the actual bolt joint 21 and nut joint 22, and nylon rope with the same diameter as the through hole 203 is preferred.

[0021] It should be noted that this embodiment only provides detailed solutions for the rigid and flexible connections between the pole sections 1. Actual surveying poles may also include other structural features, such as a cone at the bottom of the pole to facilitate inserting the pole into the ground; or graduation markings on the pole for further accurate measurement (gradations are not set for non-precise measurements, such as common red and white surveying poles). All of the above structural features are existing conventional technologies. This embodiment can adaptively add the above technical features according to actual usage needs. All of the above technical features are existing conventional technologies, and the specific setting methods are not described here.

[0022] In this embodiment, the appearance of the marker section 1 is set to a red and white visual effect, and the setting method is the same as that of the existing red and white markers.

[0023] Working principle: When assembling multiple marker sections 1 to form a stable marker, simply screw the threaded part 201 of the corresponding bolt joint 21 onto the corresponding nut joint 22. After the bolt joint 21 and the corresponding nut joint 22 are engaged, a fixed connection is formed between the corresponding two marker sections 1, which is also a rigid connection. After all the marker sections 1 are fixedly connected to each other, all the marker sections 1 together form a stable and straight marker, which can then be used for surveying and marking.

[0024] When not in use, disassemble each marker section 1. First, loosen the threaded connection between the bolt joint 21 and the nut joint 22, gradually separating adjacent marker sections 1 until they detach. At this point, the marker sections 1 are connected by connecting ropes 31, which are flexible connections. The connecting ropes 31 connect adjacent marker sections 1, but the marker sections 1 can be folded together. The folded marker sections 1 can be stacked (e.g., ...). Figure 1 ) or stacked (e.g.) Figure 2 All of these can greatly reduce the space required for storing the markers, making it easier to carry and store them. The connecting rope 31 forms a soft connection between each marker section 1, which can reduce the disarray of each marker section 1 and effectively prevent individual marker sections 1 from falling off and being lost.

[0025] Since the connecting rope 31 and the receiving groove 11 are in sliding fit, and there is no fixed connection between the connecting rope 31 and the clamp 32 and the receiving groove 11, the two marker sections 1 will not be affected by the connecting rope 31, whether they rotate relative to each other or move away from or closer to each other.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
