Description

Technical Field

[0001] This invention relates to the field of outdoor equipment, and in particular to a screw-in spiral anchor bolt earthquake-resistant outdoor tent. Background Technology

[0002] Camping tents are portable shelters used for outdoor activities such as camping and mountaineering, providing wind and rain protection. Traditional outdoor tents rely heavily on ground stakes, ballast, or simple helical stakes for anchoring, which have limited pull-out resistance. They are particularly prone to displacement or overturning in soft soil or harsh environments such as earthquakes and strong winds, posing significant safety hazards. Existing anchoring systems generally lack specific designs for earthquake resistance, resulting in insufficient anchoring depth and significant soil disturbance, making it difficult to generate sustained and effective pull-out resistance. While some designs using helical anchors offer some improvement, they typically involve vertically driven straight rods, resulting in insufficient overall stability. Furthermore, the connection between the anchor and the tent support poles is often fixed or separate, leading to poor installation convenience and system coordination. In addition, existing tent structures lack energy buffering mechanisms; the impact energy from earthquakes or wind vibrations is directly transferred to the anchoring system, easily causing connection failure.

[0003] Therefore, there is an urgent need to provide a screw-in helical anchor bolt earthquake-resistant outdoor tent to improve the safety and reliability of outdoor tents under extreme conditions. Summary of the Invention

[0004] The purpose of this invention is to provide a screw-in helical anchor bolt earthquake-resistant outdoor tent to solve the problems in the prior art.

[0005] To achieve the above objectives, the embodiments of the present invention provide the following technical solutions: According to a first aspect of the present invention, a screw-in helical anchor bolt earthquake-resistant outdoor tent is provided, comprising a plurality of support rods and an anchoring system, the anchoring system being mounted on the support rods, the anchoring system comprising: Multiple screw-in helical anchor bolts, each helical anchor bolt comprising a hollow anchor bolt body, the lower end of which is provided with a tapered drill bit; Continuous helical blades are welded to the outer surface of the anchor bolt body for screwing into the formation; A top connector is provided at the top of the anchor rod body for detachably connecting to the bottom end of the support rod; The spiral blade has a barbed structure in the middle section, which is used to compact the surrounding soil to form a pull-out resistance layer when rotating and drilling, thereby enhancing the seismic and tensile resistance.

[0006] Furthermore, the top connector is an internal threaded groove or a quick-release buckle mechanism, used to match and lock with the corresponding external thread or buckle head at the bottom of the tent support pole.

[0007] Furthermore, the multiple spiral anchor bolts are installed in a distributed, inclined layout, together forming a triangular mechanical stability system.

[0008] Furthermore, the outdoor tent also includes a tent fabric; multiple support poles are interconnected to form a tent support frame, and the tent fabric is connected to the support frame; The bottom end of the support rod is provided with a screw-in interface that matches the top connector of the helical anchor rod. By rotating the support rod, the helical anchor rod connected to it can be screwed into the ground.

[0009] Furthermore, an elastic connecting strip is connected between the tarpaulin and the support rod, which is used to absorb kinetic energy through its own deformation during earthquakes or strong winds, thereby reducing the impact on the anchoring system.

[0010] Furthermore, the screw-in interface at the bottom of the support rod is provided with an external thread that matches the internal thread groove, or the screw-in interface at the bottom of the support rod is a snap-fit ​​head that matches the quick-release snap-fit ​​mechanism.

Tighten the connection mechanism between the support rod and the spiral anchor rod to complete the fixing of a single anchor rod; S4. Repeat steps S1-S3 to complete the distributed installation of all anchor bolts, so that multiple anchor bolts form a triangular stable system with coordinated force.

[0012] Furthermore, in step S2, during the rotating drilling process, the barbed structure on the spiral blades compacts the surrounding soil, forming a pull-out resistance layer.

[0013] The embodiments of the present invention have the following advantages: The embodiments of the present invention provide a screw-in spiral anchor earthquake-resistant outdoor tent, which, through continuous spiral blades and a middle barbed structure, can effectively compact the surrounding soil during the rotating drilling process, forming a dense pull-out resistance layer, greatly enhancing the mechanical interlocking force and static friction between the anchor and the foundation, significantly improving the tent's pull-out resistance and overall stability under lateral and vertical loads such as earthquakes and strong winds, thereby improving the safety and reliability of the outdoor tent under extreme conditions.

Detailed Implementation

[0016] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0018] This embodiment provides a screw-in helical anchor bolt earthquake-resistant outdoor tent, including multiple support rods 6 and an anchoring system, wherein the anchoring system is installed on the support rods 6, as shown below. Figure 1As shown, the anchoring system includes: multiple screw-in helical anchor rods, each helical anchor rod comprising a hollow anchor rod body 1, with a conical drill bit 2 at the lower end of the anchor rod body 1; continuous helical blades 3, welded to the outer surface of the anchor rod body 1, for screwing into the ground; and a top connector 5, located at the top of the anchor rod body 1, for detachably connecting to the bottom end of the support rod 6. The helical blades 3 have a barbed structure 4 in the middle section, used to compact the surrounding soil during rotational drilling to form a pull-out resistance layer, enhancing seismic and tensile strength. Through the continuous helical blades 3 and the middle barbed structure 4, the surrounding soil is effectively compacted during rotational drilling, forming a dense pull-out resistance layer, greatly enhancing the mechanical interlocking force and static friction between the anchor rod and the foundation. This significantly improves the tent's pull-out resistance and overall stability under lateral and vertical loads such as earthquakes and strong winds, thereby enhancing the safety and reliability of the outdoor tent under extreme conditions. Furthermore, the design of the hollow anchor body 1 combined with the conical drill bit 2 at the lower end reduces the screwing resistance, enabling it to adapt to various complex geological conditions, including hard soil layers and gravel ground. The quick-release mechanism also facilitates rapid disassembly and reuse in different locations, balancing robustness and portability, and greatly expanding the product's application scenarios.

[0019] In some embodiments, such as Figure 2 As shown, the top connector 5 is an internally threaded groove or a quick-release buckle mechanism, used to match and lock with the corresponding external thread or buckle head at the bottom of the tent support pole 6. The top connector 5 of the anchor pole is directly connected to the bottom of the tent support pole 6 using an internally threaded or quick-release buckle mechanism, realizing the "pole-anchor integration" operation. No additional tools are required during installation; simply rotating the support pole 6 drives the anchor pole into the ground, simplifying the complex anchoring installation process into a single step, greatly saving manpower and time, and is particularly suitable for the needs of rapid outdoor setup.

[0020] In some embodiments, multiple helical anchor bolts are installed in a distributed, inclined layout, collectively forming a triangular mechanical stability system. This distributed, inclined layout of multiple anchor bolts creates a highly efficient triangular mechanical stability system. This design transforms single-point anchoring into a holistic stability network, effectively decomposing and offsetting impact loads from different directions, preventing tent twisting or overturning, and providing overall stiffness and stability far superior to traditional vertical anchoring methods.

[0021] In some embodiments, the outdoor tent further includes a tent fabric; multiple support rods 6 are interconnected to form a tent support frame, and the tent fabric is connected to the support frame; wherein, the bottom end of each support rod 6 is provided with a screw-in interface that matches the top connector 5 of the spiral anchor rod, and rotating the support rod 6 can drive the spiral anchor rod connected to it to screw into the ground.

[0022] In some embodiments, an elastic connecting strip connects the tarpaulin and the support rod 6, which absorbs kinetic energy through its own deformation during earthquakes or strong winds, thus mitigating the impact on the anchoring system. The elastic connecting strip between the tarpaulin and the support rod 6 constitutes a second layer of protection. During earthquakes or strong winds, the elastic strip absorbs and dissipates some of the kinetic energy through its own deformation, reducing the peak impact force transmitted to the anchoring system. This prevents stress concentration from causing instantaneous overload failure of the connecting mechanism or anchor rod, improving the system's safety redundancy and durability.

[0023] In some embodiments, the screw-in interface at the bottom of the support rod 6 is provided with an external thread that matches the internal thread groove, or the screw-in interface at the bottom of the support rod 6 is a snap-fit ​​head that matches the quick-release snap-fit ​​mechanism.

[0024] According to a second aspect of the present invention, a method for installing any of the above-described earthquake-resistant outdoor tents is provided, comprising the following steps: S1. Connect and lock the top connector 5 of the spiral anchor rod to the screw-in interface at the bottom of the tent support rod 6; S2. Align the spiral anchor rod vertically or at an angle with the ground, and by rotating the support rod 6, the support rod 6 drives the spiral blades 3 of the spiral anchor rod to drill downward into the stratum until a preset depth is reached; S3. Tighten the connection mechanism between the support rod 6 and the spiral anchor rod to complete the fixing of a single anchor rod; S4. Repeat steps S1-S3 to complete the distributed installation of all anchor bolts, so that multiple anchor bolts form a triangular stable system with coordinated force.

[0025] In some embodiments, during step S2, when the drill is rotated downwards, the barb structure 4 on the spiral blade 3 compacts the surrounding soil to form a pull-out resistance layer.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
