Description

Technical Field

[0001] This utility model belongs to the field of measuring tripod technology, specifically relating to a stable and reinforced measuring tripod. Background Technology

[0002] A surveying tripod is a tripod-shaped support device used to support surveying instruments (such as total stations, levels, GNSS receivers, etc.). It is a fundamental tool in surveying, engineering construction, geological exploration, and other fields. Its core function is to provide a stable support platform for surveying instruments, ensuring the accuracy and reliability of measurement data, while its adjustable structure can adapt to different terrains and operational needs.

[0003] Traditionally, aluminum alloys or steel were used, but modern products mostly use high-strength lightweight materials (such as carbon fiber and magnesium alloys) to balance strength and portability. When unfolding a measuring tripod, it is important to ensure that all three legs are securely locked to prevent tipping due to unilateral stress. However, since most measuring tripods on the market rely on three supporting legs for stable support, the limitations of traditional support structures are significantly exposed when encountering complex terrain such as uneven surfaces, mud, slopes, or loose soil. Three-point support can easily form "virtual fulcrums" in non-planar scenarios, and the risk of overall center of gravity shifting increases dramatically when a single leg gets stuck in mud or is suspended in the air. Utility Model Content

[0004] The purpose of this utility model is to provide a stable and reinforced measuring tripod, which aims to solve the problem that in the use of the above-mentioned equipment in the prior art, the limitations of the traditional support structure are significantly exposed when encountering complex terrain such as uneven ground, silt, slopes or loose soil layers, because the measuring tripods on the market generally rely on three supporting legs to achieve stable support. In non-planar scenarios, the three-point support is prone to forming "virtual fulcrums", and when a single leg tube sinks into silt or is suspended in the air, the risk of overall center of gravity shifting increases dramatically.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stable and reinforced measuring tripod, comprising a base and a rotating plate movably mounted on the bottom surface of the base, wherein a support plate is connected to the bottom end of the rotating plate, a telescopic plate is connected to the bottom opening of the support plate, and an insert plate is connected to the bottom end of the telescopic plate.

[0006] A side plate is connected to the inner side of the support plate. A rotating plate is rotatably connected to one side of the side plate. An adjusting plate is connected to the other end of the rotating plate. A fixed plate is connected to the surface of the adjusting plate. A rotating block is connected to the other end of the fixed plate. A center block is rotatably connected to the surface of the rotating block. A movable lead screw is connected to the surface of the adjusting plate near the fixed plate. A nut is connected to the surface of the movable lead screw.

[0007] As a preferred embodiment of the stable and reinforced measuring tripod of this utility model, the rotating plate is rotatably connected to the side plate via a rotating shaft, and three rotating plates are provided.

[0008] As a preferred embodiment of the stable and reinforced measuring tripod of this utility model, the adjusting plate and the fixed plate are open at one end to form a sliding connection structure, the movable lead rod passes through and extends to the outside of the fixed plate, and the movable lead rod and the nut are threadedly connected.

[0009] As a preferred embodiment of the stable and reinforced measuring tripod of this utility model, a fixing clamp is connected to the bottom surface of the support plate near the telescopic plate, a movable rod is connected to the opening at one end of the fixing clamp, and a linkage plate is connected to the other end of the movable rod.

[0010] As a preferred embodiment of the stable and reinforced measuring tripod of this utility model, a linkage spring is connected to one side of the linkage plate, and the other end of the linkage spring is connected to the inner wall of the opening of the fixing clamp.

[0011] As a preferred embodiment of the stable and reinforced measuring tripod of this utility model, the linkage plate is connected to a locking plate on the side opposite to the linkage spring, the locking plate and the slot opened on one side of the telescopic plate form a fitting structure, and the inner wall of the opening of the support plate is connected to a limit block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, when the measuring tripod is placed on the bottom surface, unfolds the three support plates at an angle. This causes the rotating plate to rotate along the side plate, and the adjusting plate to extend and retract at one end of the fixed plate. This, in turn, causes the rotating block at the other end of the fixed plate to rotate along the center block. This connects the three support plates into a whole. At the same time, the triangular structure formed by the adjusting plate and the fixed plate further improves the stability of the measuring tripod, ensuring that the measuring instruments on the tripod remain stable even in harsh environments such as mud, thus guaranteeing the accuracy of subsequent measurement data.

[0022] 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.

[0023] Please see Figure 1-6 The present invention provides the following technical solution: a stable and reinforced measuring tripod, including a base 1 and a rotating plate 2 movably installed on the bottom surface of the base 1. The bottom end of the rotating plate 2 is connected to a support plate 3, the bottom opening of the support plate 3 is connected to a telescopic plate 4, and the bottom end of the telescopic plate 4 is connected to an insert plate 5.

[0024] A side plate 6 is connected to the inner side of the support plate 3. A rotating plate 7 is rotatably connected to one side of the side plate 6. An adjusting plate 8 is connected to the other end of the rotating plate 7. A fixed plate 9 is connected to the surface of the adjusting plate 8. A rotating block 10 is connected to the other end of the fixed plate 9. A center block 11 is rotatably connected to the surface of the rotating block 10. A movable lead screw 12 is connected to the surface of the adjusting plate 8 near the fixed plate 9. A nut 13 is connected to the surface of the movable lead screw 12.

[0025] Preferably, the rotating plate 7 is rotatably connected to the side plate 6 via a rotating shaft, and three rotating plates 7 are provided.

[0026] In practical use, the stability of the tripod base is ensured by using a triangular rotating plate 7, avoiding arbitrary adjustments.

[0027] Preferably, the adjusting plate 8 and the fixed plate 9 are open at one end to form a sliding connection structure, the movable lead rod 12 passes through and extends to the outside of the fixed plate 9, and the movable lead rod 12 and the nut 13 are threadedly connected.

[0028] In practical use, by tightening the nut 13 on the surface of the movable lead screw 12, the adjusting plate 8 can be easily locked and stabilized at one end of the fixed plate 9, ensuring the stability of the measuring tripod.

[0029] Preferably, a fixing clamp 14 is connected to the bottom surface of the support plate 3 near the telescopic plate 4, a movable rod 15 is connected to the opening at one end of the fixing clamp 14, and a linkage plate 16 is connected to the other end of the movable rod 15.

[0030] Preferably, a linkage spring 17 is connected to one side of the linkage plate 16, and the other end of the linkage spring 17 is connected to the inner wall of the opening of the fixing clamp 14.

[0031] In practical use, the elastic extension and contraction properties of the fixing clamp 14 facilitate the automatic movement of the clamp plate 18.

[0032] Preferably, a locking plate 18 is connected to the side of the linkage plate 16 opposite to the linkage spring 17. The locking plate 18 and the slot 19 opened on one side of the telescopic plate 4 form a fitting structure. A limit block 20 is connected to the inner wall of the opening of the support plate 3.

[0033] In practical use, the card plate 18 is fitted into the slot 19 on one side of the telescopic plate 4, which facilitates the quick locking of the measuring tripod after the height is adjusted.

[0034] The working principle of this utility model is as follows: When the measuring tripod is placed on the bottom surface, the three support plates 3 are unfolded at an angle. This causes the rotating plate 7 to rotate along the side plate 6, which in turn causes the adjusting plate 8 to extend or retract at one end of the fixed plate 9. This, in turn, causes the rotating block 10 at the other end of the fixed plate 9 to rotate along the center block 11. Then, the nut 13 is tightened into the thread on the surface of the movable lead screw 12, connecting the three support plates 3 into a whole. At the same time, the triangular structure formed by the adjusting plate 8 and the fixed plate 9 further improves the stability of the measuring tripod, ensuring that the measuring tripod can withstand conditions such as silt. Even in harsh environments, the stability of the measuring instruments on the support can be guaranteed, ensuring the accuracy of subsequent measurement data. In addition, by pulling the movable rod 15 at one end of the fixed clamp 14, the linkage spring 17 on one side of the linkage plate 16 is compressed, which in turn moves the clamping plate 18. Then, the telescopic plate 4 is adjusted up and down on the support plate 3, thereby adjusting the height of the measuring tripod. After releasing the movable rod 15, the clamping plate 18 is fitted into the groove 19 on one side of the telescopic plate 4, and the limiting block 20 slides along the opening on one side of the telescopic plate 4, thus facilitating quick adjustment of the measuring tripod.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
