Description

Technical Field

[0001] This utility model relates to the field of soil and water conservation technology, and more specifically, to a soil and water conservation sign. Background Technology

[0002] In soil and water conservation efforts, monitoring stations need to be established at multiple key locations within a specific area to conduct continuous or periodic monitoring activities. To ensure the accuracy and continuity of each monitoring operation, each monitoring point is equipped with a sign to mark its specific location. However, when the displayed information needs to be updated, the existing sign structure often requires replacing the entire sign along with its supporting pole, which is complex and inefficient. Furthermore, under severe weather conditions such as strong winds, these signs, which rely solely on a single pole inserted into the soil for support, lack stability and are prone to tipping over.

[0003] Chinese patent CN219370538 U discloses a soil and water conservation sign. The sign's uprights, posts, and connecting components are designed to be detachable, facilitating on-site assembly and disassembly. During installation, the posts are directly inserted into the ground for initial support. However, due to the sign's large size, relying solely on a single post for fixation presents a challenge to its stability under strong winds and other natural forces, posing a risk of tipping over. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art above, and to propose a soil and water conservation sign.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A soil and water conservation sign includes a base frame with a pole inserted into it. A connecting rod is provided at the top of the pole, and a display board is rotatably connected to the connecting rod. A torsion spring is sleeved on the connecting rod, with one end of the torsion spring fixedly connected to the display board and the other end fixedly connected to the connecting rod.

[0007] Furthermore, the base frame includes a base plate and a threaded sleeve. Multiple inclined support rods are obliquely arranged on the threaded sleeve. The bottom of each inclined support rod is provided with a fixed threaded rod. The center of the base plate is provided with a central threaded hole to accommodate the insertion of the upright. Multiple through holes are provided around the base plate. The fixed threaded rod passes through the through holes and is threadedly connected to a lower insert sleeve. The bottom of the lower insert sleeve is provided with a cone. The threaded sleeve is provided with internal threads.

[0008] Furthermore, the upright is provided with a central thread and a lower thread, the lower end of the upright is threadedly connected to the base plate, and the middle part of the upright is threadedly connected to the threaded sleeve.

[0009] Furthermore, a lower limiting plate is provided at the junction of the upright and the connecting rod, and the upper end of the connecting rod is provided with an external thread.

[0010] Furthermore, the back of the display panel is provided with a first sleeve and a second sleeve, which cooperate with the connecting rod.

[0011] Furthermore, the upper end of the connecting rod passes through the second sleeve, the torsion spring, and the first sleeve in sequence, and is then threadedly connected to an upper locking plate.

[0012] Furthermore, when a display board is rotatably connected to the connecting rod, the lower end of the second sleeve abuts against the lower limit plate.

[0013] Compared with existing technologies, the advantages of this utility model are as follows: This utility model achieves a perfect combination of stable support, flexible display, and automatic return. The base frame adopts a combination design of a base plate and a threaded sleeve, along with an inclined support rod and a conical lower sleeve, which greatly enhances the stability and wind resistance of the sign. The rotating connection between the connecting rod and the display board, supplemented by the automatic return function of the torsion spring, allows the display board to flexibly adjust its angle under external force and quickly return to its original position after the wind subsides. This ensures the stability and safety of the display board during long-term use, providing a solid and reliable guarantee for the publicity and instruction of soil and water conservation work.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0019] like Figures 1-3 As shown, a soil and water conservation sign includes a base frame 1, which provides a stable support foundation for the entire sign. A vertical pole 2 is inserted into the base frame, and a connecting rod 24 is provided at the top of the vertical pole. A display board 3 is rotatably connected to the connecting rod. This rotatable connection design allows the display board to be flexibly adjusted in angle according to actual conditions. A torsion spring 4 is sleeved on the connecting rod, with one end of the torsion spring fixedly connected to the display board and the other end fixedly connected to the connecting rod. This connection method ensures that the torsion spring can function effectively, allowing the display board to quickly return to its original position after being subjected to external force.

[0020] In at least one embodiment, the base frame includes a base plate 13 and a threaded sleeve 11. Multiple inclined support rods 12 are obliquely arranged on the threaded sleeve, and a fixing threaded rod 16 is provided at the bottom of each inclined support rod. A central threaded hole for inserting a vertical pole is provided in the center of the base plate, and multiple through holes are provided around the base plate. The fixing threaded rod passes through the through holes and is threadedly connected to a lower insert sleeve 14. A cone head 15 is provided at the bottom of the lower insert sleeve, and internal threads are provided inside the threaded sleeve. The cone head design allows the lower insert sleeve to be inserted into the ground more easily and increases its grip.

[0021] Correspondingly, the upright is provided with a central thread 21 and a lower thread 22. The lower end of the upright is threadedly connected to the base plate, and the middle part of the upright is threadedly connected to a threaded sleeve. This connection method not only achieves a secure connection between the upright and the threaded sleeve, but also allows the height to be adjusted by rotating the upright.

[0022] In at least one embodiment, a lower limiting plate 23 is provided at the junction of the upright and the connecting rod, and the upper end of the connecting rod is provided with an external thread.

[0023] In at least one embodiment, the back of the display panel is provided with a first sleeve 31 and a second sleeve 32, and the first sleeve and the second sleeve cooperate with the connecting rod.

[0024] Furthermore, the upper end of the connecting rod passes sequentially through the second sleeve, the torsion spring, and the first sleeve, and is then threadedly connected to an upper locking plate 25. The addition of the upper locking plate allows the display plate to be more securely fixed to the connecting rod, preventing it from falling off.

[0025] The design is further refined so that when a display board is rotatably connected to the connecting rod, the lower end of the second sleeve abuts against the lower limit plate. This design not only increases the stability of the display board but also ensures that the display board will not interfere with the upright or connecting rod during rotation.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
