Description

Technical Field

[0001] This utility model relates to the field of meteorological observation equipment technology, specifically to a wind vane that is easy to assemble and has an adjustable height. Background Technology

[0002] A wind vane is a common meteorological observation device used to indicate wind direction and is widely used in weather stations, construction sites, agricultural environmental monitoring, and other applications. Currently, most wind vanes on the market adopt an integrated structure or a fixed segmented design, resulting in large transport volume and inconvenient handling. Especially when installed at high altitudes or in complex terrain, traditional wind vanes suffer from low installation efficiency and poor adaptability due to their non-removable nature or limited adjustment range.

[0003] While some existing technologies offer detachable wind vanes, their connection structures mostly rely on bolt fastening or plug-in methods, resulting in cumbersome assembly processes and insufficient connection stability, making them susceptible to loosening due to wind forces. Furthermore, the length of the marker poles is often fixed, preventing flexible adjustment based on observation height and limiting their applicability in various installation environments.

[0004] Therefore, there is an urgent need for a new type of weather vane that is quick to assemble, adjustable in length, stable in installation, and highly adaptable, in order to solve the aforementioned problems existing in the actual use of current products. Utility Model Content

[0005] This utility model designs a wind vane, which solves the technical problems of existing wind vanes, such as inconvenient transportation and installation, insufficient connection stability, and inability to adapt to different installation height and angle requirements due to their fixed structure.

[0006] To solve the aforementioned technical problems, the present invention adopts the following solution: A weather vane includes a tail fin assembly, a main rod assembly, a support rod assembly, and a clip assembly. The clip assembly includes a clip and a hinged connection. One end of the support rod assembly is detachably connected to a threaded hole in the hinged connection via a horizontal connecting thread. The threaded structure can also adjust the rotation angle of the tail fin assembly and the main rod assembly. The main rod assembly is mounted on the upper end of the support rod assembly, and the tail fin assembly is mounted on the top of the main rod assembly.

[0007] Preferably, the hinged connection is connected to the clamp via a hinge shaft, allowing the support rod assembly to swing in a vertical plane.

[0008] Preferably, the support rod assembly includes a support rod, a horizontal column, and a horizontal column cover. The support rod is provided with an assembly port and an observation port. The horizontal column is installed into the support rod through the assembly port and the assembly port is closed by the horizontal column cover.

[0009] Preferably, the level column is equipped with a level, and the observation port is used to expose the level for observation.

[0010] Preferably, the length of the assembly port is not less than the axial length of the horizontal column, and the length of the observation port is less than the axial length of the horizontal column.

[0011] Preferably, the main rod assembly includes a main rod, a bearing column, a bearing, a bearing sleeve, and a bearing cap. The bearing is installed inside the bearing sleeve, and the bearing sleeve is threadedly connected to the mounting groove at the other end of the support rod. The lower end of the bearing column is inserted into the inner ring of the bearing, and the upper end of the bearing column is connected to the main rod.

[0012] Preferably, the bearing cap covers the bearing and bearing sleeve.

[0013] Preferably, the tail fin assembly includes a tail fin, and the main rod is provided with a slot, through which the tail fin is fixedly connected to the main rod.

[0014] Preferably, the horizontal connecting thread enables stepless angle adjustment of the support rod assembly in the horizontal direction.

[0015] Preferably, the weather vane is installed at a shooting range or a golf course.

[0016] This weather vane has the following advantages compared to existing weather vanes: (1) This utility model designs the wind vane as four detachable components: tail fin, main rod, support rod and clip, which greatly facilitates transportation and handling. Users can quickly assemble it on site, which significantly improves installation efficiency. It is especially suitable for complex installation environments such as high altitude and field.

[0017] (2) This utility model adopts a horizontal connection threaded hinge structure between the support rod and the clamp assembly, which can realize stepless rotation adjustment in the horizontal direction to align with the wind direction, and can swing in the vertical plane to adapt to the tilt of the installation surface, thereby improving the adaptability and pointing accuracy of the equipment to different installation scenarios.

[0018] (3) This utility model encapsulates a level column with a level inside the support rod and displays the level status in real time through the observation port. Users can intuitively and conveniently make fine adjustments to the level during the installation process to ensure that the wind vane is in a level state, thereby ensuring the accuracy of the observation results.

[0019] (4) The present invention adopts a bearing support structure for the main rod assembly, which has low frictional resistance, allowing the tail fin to rotate sensitively and smoothly with changes in wind direction; at the same time, the design of the bearing cover effectively prevents dust and rainwater from entering, improving the durability of the bearing and the overall reliability.

[0020] (5) This utility model adopts standardized connection methods such as threads and plugs between the components, which makes it easy to assemble and disassemble, facilitates daily inspection, cleaning or replacement of parts, and reduces the cost and difficulty of later maintenance.

[0021] (6) This utility model can be securely clamped to carriers such as railings and windowsills of different specifications through the clamp assembly. Combined with the angle adjustment and horizontal calibration functions, the wind vane can work reliably and stably in various occasions such as meteorological observation, building construction, and agricultural monitoring.

[0025] The following is combined with Figures 1 to 4 The present invention will be further described below: like Figure 1 As shown, the wind vane provided by this utility model adopts a modular design and is mainly composed of four detachably connected parts: tail fin assembly A, main rod assembly B, support rod assembly C, and clip assembly D.

[0026] The clip assembly D includes an adjustable clip 7 and a hinged connection 6. The clip 7 is used to hold the device onto a mounting surface such as a railing or windowsill. The hinged connection 6 has a connecting hole. The lower end of the support rod 3 of the support rod assembly C is screwed into and fixed in this connecting hole via a horizontal connecting thread 15, thereby connecting the support rod 3 to the clip 7. This threaded connection allows the user to steplessly adjust the wind vane's direction (i.e., azimuth) in the horizontal plane by rotating the entire support rod 3 to adapt to different observation directions. After adjustment, the self-locking property of the horizontal connecting thread 15 maintains angular stability. The hinged connection 6 is connected to the clip 7 via a hinge shaft 14, allowing the support rod 3 to swing in the vertical plane to adapt to the tilt angle of the mounting surface.

[0027] The support rod assembly C is a key component that combines ease of assembly with precision in use. It includes the support rod 3, the horizontal column 11, and the horizontal column cap 12.

[0028] The support rod 3 has two openings on its two sides: an assembly opening and an observation opening 13. The two openings have different functions and work together. The length of the assembly opening is designed to be greater than or equal to the axial length of the horizontal column 11. Its main function is to allow the horizontal column 11 to be inserted axially into the internal cavity of the support rod 3 during assembly.

[0029] The support rod 3 is provided with an observation port 13. The length of the observation port 13 is less than the axial length of the horizontal column 11. Its design serves a dual purpose: firstly, it acts as an observation window, exposing the level integrated on the surface of the horizontal column 11 for easy observation and calibration by the user; secondly, due to its short length, it can effectively limit the axial movement of the horizontal column 11, preventing the horizontal column 11 from accidentally coming out of this opening, thus ensuring the safety and reliability of use.

[0030] After the horizontal column 11 is inserted into the support rod 3 through the assembly port, the horizontal column cover 12 is used to cover and close the assembly port, thereby encapsulating the horizontal column 11 inside the support rod 3 and completing the assembly of the support rod assembly C.

[0031] The main rod assembly B is the core component that enables the wind vane to rotate sensitively and smoothly. It includes the main rod 2, bearing column 5, bearing 9, bearing sleeve 10, and bearing cover 8.

[0032] The bearing sleeve 10 serves as the mounting base for the bearing and has an internal mounting hole. The bearing 9 is placed in this mounting hole. The lower end of the bearing sleeve 10 has an external thread, which is screwed into the mounting groove 4 at the top of the support rod 3 to the corresponding threaded mounting hole for fixation, thereby mounting the entire rotary support structure onto the support rod 3.

[0033] One end of the bearing post 5 is inserted into the inner ring of the bearing 9, forming a tight fit or transition fit with the inner ring, serving as a rotating shaft. The other end of the bearing post 5 is connected and fixed to the mounting hole at the upper end of the main rod 2, thereby connecting the main rod 2 and the bearing post 5 into one unit.

[0034] The bearing cover 8 is fitted onto the bearing post 5 and is located above the bearing 9 and bearing sleeve 10. Its main function is to block the upper opening of the bearing 9 and bearing sleeve 10 downwards, preventing dust, rainwater and other foreign objects from entering the bearing, protecting the bearing, extending its service life, and making the appearance more neat.

[0035] This structure together forms a low-friction, high-precision rotating pair. When wind acts on the tail fin, the force is transmitted through the main rod 2 to the bearing column 5, causing it and the inner ring of the bearing 9 to rotate together, while the bearing sleeve 10 and the support rod 3 remain stationary, thus achieving flexible and stable rotation of the main rod 2 and the tail fin 1 above it.

[0036] Tail fin assembly A includes a streamlined tail fin 1. The tail fin 1 is fixedly connected to the top of the main rod 2 via a mounting slot 4 at its bottom. When wind acts on the tail fin 1, it will cause the main rod 2 to rotate until the tail fin 1 points in the direction of the wind, thus visually indicating the wind direction.

[0037] The assembly and use process of this utility model is as follows: 1. Pre-install the support rod assembly: First, insert the horizontal column 11 into the support rod 3 through the larger mounting port along the axis, and then cover the horizontal column cover 12 to close the mounting port.

[0038] 2. Main rod assembly pre-assembly: Press the bearing 9 into the mounting hole of the bearing sleeve 10. Screw the bearing sleeve 10 into the threaded mounting hole at the top of the support rod 3 and secure it. Insert the lower end of the bearing post 5 into the inner ring of the bearing 9, and connect the upper end of the bearing post 5 to the inside of the main rod 2. Finally, put the bearing cover 8 on the bearing post 5 to cover the bearing area.

[0039] 3. On-site installation and fixing: Clamp clip 7 to the selected installation location, such as a railing.

[0040] 4. Connection and Orientation Adjustment: Screw the pre-installed support rod assembly C into the connecting hole of the hinge connection part 6 of the clamp assembly D through the horizontal connecting thread 15 at one end. Perform preliminary adjustment and locking of the horizontal azimuth angle by rotating the support rod 3.

[0041] 5. Fine-tuning and Completion: Observe the level on the level column 11 through the small observation port 13 on the support rod 3. Fine-tune the rotation angle of the support rod 3 until the level shows that the support rod 3 is in a precisely level state. Finally, install the tail fin 1 onto the top of the main rod 2.

[0042] The above installation sequence can be adjusted according to the installation environment to meet the installation requirements.

[0043] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the implementation of the present invention is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
