Abstract
Description
Technical Field
[0001] This utility model relates to the field of outdoor equipment technology, and in particular to a camping tent with multiple wind-resistant structures. Background Technology
[0002] With the increasing popularity of outdoor activities, the need for quickly constructing a safe, comfortable, and protective temporary shelter in the wild has become a priority. Camping tents have become the preferred equipment for outdoor activities, as they create a relatively enclosed microclimate space. In cold weather, they can effectively retain body heat (insulation); in hot weather, their good ventilation design provides shade, and they keep the interior dry and warm in rainy or snowy weather. The waterproof base insulates the body from the cold, damp ground, preventing heat loss and moisture intrusion.
[0003] However, traditional camping tents mostly use a single-layer pole cross-support structure, which is fixed by ground pegs and guy lines. In strong winds, the tents are not stable enough and are prone to deformation or overturning.
[0004] Therefore, there is an urgent need for a camping tent with multiple wind-resistant structures. Summary of the Invention
[0005] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a camping tent with multiple wind-resistant structures.
[0006] This utility model provides a camping tent with multiple wind-resistant structures, including: The tent body includes a curtain for isolating the space; the top of the tent body is conical in shape and the bottom is cylindrical in shape. A water storage bladder is connected to the bottom of the curtain and has a water storage cavity inside for storing water. Multiple windbreak ropes; Multiple ground stake assemblies are inserted into the ground, and the ground stake assemblies are connected to the top of the curtain via the windproof rope.
[0007] According to the technical solution provided in the embodiments of this application, the ground stake assembly includes: The nail body has a sliding groove extending vertically at the top and multiple rotating grooves on the outer side surface; the rotating grooves are provided with barbs. An arc-shaped rod is disposed in the rotating groove and is rotatably connected to the barb, with its rotation axis direction perpendicular to the vertical direction; A sliding rod, located within the sliding groove, can move vertically to drive the barbs to swing up and down. Multiple fixing parts are provided on the nail body to restrict the movement of the sliding rod; The striking part includes a striking plate disposed at the top of the nail body, the striking plate being used to withstand striking.
[0008] According to the technical solution provided in the embodiments of this application, the sliding groove includes a first sliding groove and a plurality of second sliding grooves; the first sliding groove is formed at the top of the nail body and extends in a vertical direction; the plurality of second sliding grooves are formed on the outer side surface of the nail body, and each second sliding groove is connected to the first sliding groove; a first slider is provided in the second sliding groove, one end of the first slider is connected to the sliding rod, and the other end abuts against the barb; the sliding rod drives the barb to swing up and down through the first slider.
[0009] According to the technical solution provided in the embodiments of this application, the fixing part includes: Multiple first fixing grooves are formed on the inner wall of the first sliding groove; A fixing block is provided in the first fixing groove; A first elastic element is disposed in the first fixing groove, with one end connected to the first fixing groove and the other end connected to the first elastic element; Multiple second fixing grooves are formed on the side surface of the sliding rod; the second fixing grooves fit into the fixing block.
[0010] According to the technical solution provided in the embodiments of this application, the striking part includes: A striking bracket is located at the top of the nail body; Two striking plates, each striking plate having its bottom rotatably connected to the striking bracket, with its rotation axis perpendicular to the vertical direction; each striking plate has a fixing groove at its top; The fixing rod is detachably connected to the two striking plates via the fixing groove.
[0011] According to the technical solution provided in the embodiments of this application, the ground stake assembly further includes a force-saving lever, the force-saving lever is provided with a collar, the collar is fitted outside the sliding rod; the top of the sliding rod is provided with a sliding block, and the collar abuts against the bottom end of the sliding block.
[0012] According to the technical solution provided in the embodiments of this application, the water storage bladder is provided with a water inlet communicating with the top of the water storage cavity and a water outlet communicating with the bottom of the water storage cavity.
[0013] According to the technical solution provided in the embodiments of this application, it also includes a fixed skirt at the bottom of the curtain, the fixed skirt abutting against the ground; it also includes a fixing nail, the fixing nail penetrating the fixed skirt and being inserted into the ground.
[0014] Compared with the prior art, the beneficial effects of this utility model are: The conical top of the tent body of this utility model utilizes aerodynamic principles to guide airflow and reduce the force of wind at the source. The water storage bladder at the bottom provides stable counterweight to prevent the tent from tipping over. Furthermore, the tent is strongly anchored to the ground by external windproof ropes and ground pegs to resist wind pull. This constitutes three lines of wind protection, which greatly improves the wind resistance performance of this device.
[0015] Furthermore, the emptied and folded water bladder takes up almost no extra space and does not significantly increase the weight of the backpack. This makes this wind-resistant tent no different from a regular tent when stored and carried, perfectly solving the core pain point of heavy-duty windproof tents being bulky and inconvenient to carry.
[0016] The barbs of the ground stake assembly in this invention can be retracted, resulting in low resistance, much like a smooth nail, making it easy to drive into the ground. The barbs can also be extended to create a strong anchoring effect, with pull-out resistance far exceeding that of conventional ground stakes. This provides crucial safety for tents in strong winds. Through the sliding rod and fixing part, users can actively select and lock the working mode of the ground stake assembly according to soil conditions and weather conditions, balancing convenience and ultimate reliability. At the same time, the special striking plate design extends the product's service life.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.
[0021] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.
[0022] Please refer to Figures 1-6 An embodiment of this utility model provides a camping tent with multiple wind-resistant structures, including: The tent body 1 includes a curtain 11 for isolating the space; the top of the tent body 1 is conical and the bottom is cylindrical. Water storage bladder 2 is connected to the bottom of curtain 11 and has a water storage cavity 23 inside for storing water; Multiple windproof ropes 5; Multiple ground peg assemblies 4 are inserted into the ground, and the ground peg assemblies 4 are connected to the top of the curtain 11 via windproof ropes 5.
[0023] When using it, set up the main body of the tent 1 and fill the water storage bladder 2 with water.
[0024] In this invention, the tent body 1, with a conical top and cylindrical bottom, can smoothly divert incoming airflow under strong wind conditions, thereby greatly reducing wind resistance and wind pressure, and helping to improve wind resistance. The water storage bladder 2, located at the bottom of the tent body 1, adds significant weight to the base of the tent body 1 when filled with water, significantly lowering the overall center of gravity of the tent. This makes the tent more stable in the wind, like a self-sustaining toy, greatly enhancing wind resistance and preventing the tent from being overturned. When the wind blows towards the tent body 1, it generates an upward lift force on the top of the tent body 1. The diagonally taut windproof lines 5 decompose this upward force into downward pressure and outward tension. The downward pressure is transmitted to the ground through the tent poles, enhancing stability; the outward tension is borne by the firmly driven ground pegs 4, thus firmly anchoring the tent to the ground and effectively preventing the tent body 1 from being blown down or pulled up.
[0025] In addition, when disassembling, the water bladder 2 is connected to the bottom of the curtain 11. After the water in the water bladder 2 is drained, the water bladder 2 can be folded and stored together with the curtain 11. The emptied and folded water bladder 2 takes up almost no extra space and does not significantly increase the weight of the backpack, greatly improving the portability of the tent.
[0026] In some embodiments, the ground stake assembly 4 includes: The nail body 41 has a sliding groove 43 extending vertically at the top and multiple rotating grooves 44 on the outer side surface; the rotating grooves 44 are provided with barbs 411. An arc-shaped rod 42 is disposed in a rotating groove 44 and is rotatably connected to a barb 411, with its rotation axis direction perpendicular to the vertical direction. The sliding rod 45 is located in the sliding groove 43 and can move in the vertical direction to drive the barb 411 to swing up and down. Multiple fixing parts 46 are provided on the nail body 41 to restrict the movement of the sliding rod 45; The striking part 48 includes a striking plate 482 disposed at the top of the nail body 41, the striking plate 482 being used to withstand striking.
[0027] like Figures 4-6As shown, the nail body 41, sliding groove 43, and rotating groove 44 serve as the mounting base for subsequent components, while the arc-shaped rod 42 provides a rotation axis for the barb 411. When the ground stake assembly 4 is driven into the ground, the soil exerts an upward force on the barb 411, which drives the barb 411 to retract (swing) inward towards the nail body 41, greatly reducing the resistance during driving and allowing the ground stake assembly 4 to easily reach the predetermined depth. When the windproof rope 5 is subjected to an upward pull and attempts to pull out the ground stake assembly 4, the tips of the barbs 411 will open outward due to the force, deeply "biting" the surrounding soil and forming a strong mechanical interlock. This structure provides a grip force far exceeding that of ordinary straight ground stakes, effectively preventing the ground stake from being pulled out and greatly improving the wind resistance of this device.
[0028] Users can actively control the retraction or extension of the barbs 411 by operating the sliding lever 45 (e.g., pushing it to the bottom or pulling it to the top). Before driving in the peg assembly 4, the sliding lever 45 can be pushed to the top to retract the barbs 411, ensuring a smooth driving process. After driving in, the fixing part 46 locks in place, forcing the barbs 411 to extend for maximum immediate tensile strength.
[0029] The striking part 48 provides a flat, solid bearing surface, making it easy for the user to strike with a hammer. This avoids direct impact on other potentially fragile parts, protects the internal mechanical structure, and makes force transmission more efficient, making the hammering process safer and less strenuous.
[0030] In some embodiments, the sliding groove 43 includes a first sliding groove 431 and a plurality of second sliding grooves 432; the first sliding groove 431 is formed at the top of the nail body 41 and extends in a vertical direction; the plurality of second sliding grooves 432 are formed on the outer side surface of the nail body 41, and each second sliding groove 432 is connected to the first sliding groove 431; a first slider 451 is provided in the second sliding groove 432, one end of the first slider 451 is connected to the sliding rod 45, and the other end abuts against the barb 411; the sliding rod 45 drives the barb 411 to swing up and down through the first slider 451.
[0031] Furthermore, the size of the barbs 411 gradually decreases from top to bottom; the sliding groove 43 also includes a plurality of third sliding grooves 433 opened on the outer side surface of the nail body 41, and a second slider 452 is provided in the third sliding groove 433. One end of the second slider 452 is connected to the sliding rod 45, and the first slider 451 and the second slider 452 abut against the barbs 411 of different sizes.
[0032] like Figure 4 and Figure 5As shown, the "one main, multiple auxiliary" channel design of the first sliding groove 431 and multiple second sliding grooves 432 decomposes and transmits the single vertical movement of the sliding rod 45 to multiple sides in different directions. The first sliding groove 431 is responsible for guiding and bearing the main axial movement, while the multiple second sliding grooves 432 are responsible for converting this force into the action of driving each barb 411. At the same time, the first sliding groove 431 and multiple second sliding grooves 432 physically separate the main transmission path and the sub-transmission path, making the force transmission path clear, reducing interference between moving parts, and improving the stability and reliability of the entire mechanism. When the sliding rod 45 moves up and down, it drives the first slider 451 to move up and down synchronously within the second sliding groove 432. Compared with simple direct hinge of rods, the movement of the first slider 451 within the groove is more stable and less prone to jamming. It pushes the barbs 411 through continuous lateral contact. This surface contact can withstand greater force than point contact or line contact, resulting in higher transmission efficiency and less wear.
[0033] When the ground stake assembly 4 is under force, the closer it is to the ground, the more complex its interaction with the soil becomes, and the greater the resistance it experiences. Placing the larger barbs 411 at the top allows them to utilize their larger lever arm and contact area to provide the primary, strong pull-out force. The smaller barbs 411 at the bottom, on the other hand, allow for smoother passage through the soil during insertion, reducing resistance while still providing auxiliary anchoring. The introduction of the third sliding groove 433 and the second slider 452 provides independent guiding and transmission mechanisms for different groups of barbs 411, avoiding the jamming or asynchronous problems that might occur if all barbs 411 are driven by a single mechanism. Each slider moves within its own groove, reducing interference between moving parts and making the entire transmission process smoother and more reliable.
[0034] In some embodiments, the fixing part 46 includes: Multiple first fixing grooves 461 are formed on the inner wall of the first sliding groove 431; The fixing block 463 is disposed in the first fixing groove 461; The first elastic element 464 is disposed in the first fixing groove 461, with one end connected to the first fixing groove 461 and the other end connected to the first elastic element 464. Multiple second fixing grooves 462 are formed on the side surface of the sliding rod 45; the second fixing grooves 462 fit into the fixing block 463.
[0035] like Figures 4-6As shown, the first fixing groove 461, fixing block 463, and first elastic element 464 on the inner wall of the first sliding groove 431 cooperate with the second fixing groove 462 on the side surface of the sliding rod 45, which can effectively prevent the sliding rod 45 from moving accidentally due to vibration or slight external force, ensuring the stability of the working state. In addition, the multiple second fixing grooves 462 correspond one by one to the key positions where the sliding rod 45 needs to be locked. Users can adjust the position by engaging the fixing block 463 with different second fixing grooves 462 according to their needs, which greatly improves the applicability of this device.
[0036] In some embodiments, the striking part 48 includes: Striking bracket 481, located at the top of nail body 41; Two striking plates 482 are provided, and the bottom of each striking plate 482 is rotatably connected to the striking bracket 481, with its rotation axis perpendicular to the vertical direction; each striking plate 482 is provided with a fixing groove 484 at its top. The fixing rod 483 is detachably connected to the two striking plates 482 via the fixing groove 484.
[0037] like Figure 4 and Figure 5 As shown, the striking bracket 481 is a key component that bears and transmits the striking force. It smoothly transfers the impact force received by the striking plate 482 to the robust nail body 41, protecting internal precision mechanisms such as the sliding rod 45 from direct impact. It also provides a sturdy and durable pivot point for the striking plate 482, ensuring that it rotates smoothly and remains stable even after prolonged and repeated use and stress. The two striking plates 482 can be rotated and unfolded to form a wide flat surface, facilitating powerful strikes with a large-headed entrenching tool or hammer. The large contact area prevents slippage. When the fixing rod 483 is inserted into the fixing slot 484, it tightly locks the two independent striking plates 482 together, making them a rigid and stable integrated structure. This ensures that the striking force is evenly distributed across the entire striking bracket 481 and nail body 41, preventing damage to components due to single-point stress or imbalance.
[0038] In some embodiments, the ground stake assembly 4 further includes a force-saving lever 47, which is provided with a collar 471, which is fitted onto the sliding rod 45; the top of the sliding rod 45 is provided with a sliding block 453, and the collar 471 abuts against the bottom end of the sliding block 453.
[0039] When it is necessary to pull the ground stake assembly 4 out of the ground, the user presses down the long arm of the effort-saving lever 47, the collar 471 pushes the sliding block 453 upward, causing the sliding rod 45 to move upward, thereby retracting the barbs 411, and then pulling out the ground stake assembly 4.
[0040] like Figure 4 and Figure 5 As shown, when the user presses down the long lever arm of the effort-saving lever 47, the collar 471 will generate an amplified upward force at the top of the sliding rod 45. The collar 471 pushes the sliding block 453 upward, making it very easy to overcome the locking of the fixing part 46 and drive all the barbs 411 to retract, which in turn facilitates the subsequent removal of the ground stake assembly 4 from the ground, greatly simplifies the recycling process of the ground stake assembly 4, and saves a lot of physical strength.
[0041] In some embodiments, the water storage bladder 2 is provided with an inlet 21 communicating with the top of the water storage chamber 23 and an outlet 22 communicating with the bottom of the water storage chamber 23.
[0042] Furthermore, the point where the drain outlet 22 connects to the bottom of the water storage cavity 23 is the lowest end of the water storage cavity 23.
[0043] like Figures 1-3 As shown, during the water filling process, the air inside the water reservoir 2 can be naturally expelled through the water inlet 21, preventing air from being trapped inside and forming an "airlock," thus ensuring smooth water filling and easily filling the water reservoir 2 completely. The drain outlet 22 is positioned at the lowest point; when opened, the water reservoir 2 can be completely and cleanly emptied by gravity alone, without needing to squeeze or lift it. This ensures maximum drainage before storage, contributing to lightweight folding.
[0044] In some embodiments, the screen 11 is further provided with a fixed skirt 3 at the bottom end, the fixed skirt 3 abutting against the ground; and a fixing nail 31 is further provided, the fixing nail 31 passing through the fixed skirt 3 and being inserted into the ground.
[0045] like Figure 1 and Figure 2 As shown, strong winds often seep in through the gap between the tent bottom and the ground, not only stirring up dust but also generating a force that lifts the tent upwards, severely affecting stability. The fixed skirt 3 tightly covers the ground, effectively blocking this airflow channel and fundamentally eliminating the safety hazard caused by bottom-entry winds. Furthermore, the fixed skirt 3 forms a second barrier (the first being the tent bottom itself), better preventing ground moisture intrusion and blocking crawling insects (such as ants and centipedes) from entering the tent through the gaps, improving comfort and hygiene. The fixing pegs 31 firmly "nail" the fixed skirt 3 to the ground, ensuring it remains in contact with the ground at all times, making the seal durable and reliable. The fixing pegs 31 also provide additional, densely distributed fixing points for the tent body 1, further strengthening the connection between the tent and the ground and improving stability.
