Description

Technical Field

[0001] This utility model relates to the field of outdoor equipment technology, and in particular to a tent peg head. Background Technology

[0002] In camping and outdoor activities, tent pegs are essential accessories for securing equipment such as tents and tarps, and their performance directly affects the stability and safety of the entire structure. Common tent pegs typically consist of two parts: a peg head and a peg shaft.

[0003] Existing tent peg heads on the market have significant shortcomings in practical use. On the one hand, the connection structure between the peg head and the peg pole is poorly designed, resulting in poor connection stability and a tendency to loosen or even detach, severely affecting the securing effect. On the other hand, existing peg heads have a single structure, making it difficult to adapt to different specifications or styles of peg poles, thus limiting their versatility and applicability. Utility Model Content

[0004] The purpose of this utility model is to provide a tent peg head to solve the problems of poor connection stability between the tent peg rod and the tent peg head in the prior art, easy loosening or detachment, and inability to adapt to different styles of tent peg rods.

[0005] To achieve the above objectives, the solution of this utility model is as follows: a tent peg head, including a connecting post and at least one hook portion located on its side, wherein the connecting post has a through-hole in the middle, and the cross-section of the connecting hole is a trapezoidal structure that is wider at the top and narrower at the bottom, and the connecting hole is used for inserting and connecting the tent peg rod.

[0006] Furthermore, the cross-section of the connecting hole is an isosceles trapezoid.

[0007] Furthermore, the upper diameter D and lower diameter d of the connecting hole satisfy the following condition: D / d = 1.05~1.1.

[0008] Furthermore, the upper diameter D of the connecting hole is 6-9 mm, and the lower diameter d is 5.5-8.5 mm.

[0009] Furthermore, each of the two sides of the connecting post has a wing-shaped hook portion, which bends outward and downward from the side of the connecting post, forming an angle of 15 to 30° between the hook portion and the connecting post.

[0010] Furthermore, an arc-shaped transition area is formed below the hook portion, and the radius of curvature of the arc-shaped transition area is in the range of 4.0~5.0mm; the side thickness t of the hook portion is ≥4.5mm.

[0011] Furthermore, the top of the connecting column protrudes beyond the top of the hook portion, and the top of the connecting column extends in all directions to form a support platform at the top of the hook portion.

[0012] Furthermore, at least one of the hook portions has a functional hole for securing a rope or bandage.

[0013] Furthermore, a reinforcing structure is provided at the connection between the hook and the connecting post. This reinforcing structure is an arc-shaped reinforcing rib, which smoothly transitions between the root of the hook and the side wall of the connecting post.

[0014] Furthermore, both sides of the connecting column extend outward, with one side forming a right-angle hook portion and the other side forming a horizontal hook portion, which has a functional hole.

[0015] After adopting the above solution, the beneficial effects of this utility model are as follows:

[0016] 1. Improved Connectivity and Stability: The connecting hole of the ground stake head in this invention adopts an inverted frustum design that is wider at the top and narrower at the bottom. This not only facilitates the insertion and assembly of the ground stake rod but also provides excellent sizing compatibility and connection stability. This structure is particularly suitable for ground stake rods with tapered limiting blocks on the outer periphery. During assembly, as the ground stake rod moves downward, a gradual clamping effect is generated between its limiting block and the inner wall of the connecting hole, forming a self-locking structure. This improves the connection stability between the ground stake rod and the ground stake head, effectively preventing loosening, shaking, or detachment during use.

[0017] 2. Excellent Structural Strength and Fatigue Resistance: This invention employs multiple structural reinforcement methods, including optimizing the hook angle, increasing the hook thickness, setting an arc-shaped transition zone, and adding arc-shaped reinforcing ribs in key stress areas, to create a highly efficient load-bearing frame. This design effectively disperses external loads and avoids stress concentration, thereby significantly improving the overall impact resistance, fracture resistance, and deformation resistance of the peg head. This extends the product's service life in harsh outdoor environments, enabling it to withstand greater and more frequent outdoor pulling and impact forces. Attached Figure Description

[0032] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1:

[0034] This embodiment provides a tent peg head, such as Figures 1 to 6 As shown, it includes a connecting post 1 and two hook parts 2 located on its side. The hook parts 2 have a wing-like structure. The connecting post 1 is used to connect the ground peg pole 5, while the hook parts 2 are used to hook ropes to bear the tension of the tent.

[0035] <Connecting Hole 11>

[0036] like Figure 1 As shown, the connecting post 1 has a through-hole 11 in the middle, through which the ground nail rod 5 is inserted and connected for fixation.

[0037] like Figure 2 and Figure 3 As shown, the cross-section of the connecting hole 11 is an isosceles trapezoidal structure that is wider at the top and narrower at the bottom. This structure has a guiding function during assembly. When the ground nail rod 5 (especially the one with threads on its outer circumference) is inserted from the top of the connecting hole 11, it can guide the rod body with threads on its outer circumference or other structures to pass smoothly, which significantly improves the convenience of assembly and is superior to the traditional straight hole structure.

[0038] The lower diameter of the connecting hole 11 is approximately equal to the diameter of the rod portion of the ground stake 5, thereby effectively limiting the radial movement of the ground stake 5 and preventing it from wobbling within the hole. The upper diameter D of the connecting hole 11 is designed to be 1.05 to 1.1 times the lower diameter d of the connecting hole 11. This size range ensures the guiding function while also ensuring that it is smaller than the diameter of the head of the ground stake 5, thus preventing the head of the ground stake 5 from accidentally falling into the connecting hole 11.

[0039] This type of connecting hole 11, which is wider at the top and narrower at the bottom, has good adaptability and can be used for various styles of ground stake rods 5.

[0040] Firstly, it is suitable for ground nail rods 5 of uniform diameter with no outer circumference of the stop block 51. After such ground nail rods 5 are inserted into the connecting hole 11, rubber rings or other fasteners can be fitted on the rod body part below the nail head to prevent the ground nail rod 5 from moving upwards.

[0041] Secondly, it is particularly suitable for ground nail rods 5 with limiting blocks 51 on the outer periphery, such as... Figure 3 and Figure 4 As shown, the limiting block 51 typically has a tapered structure with its width gradually increasing from bottom to top. During assembly, as the ground stake rod 5 moves downward, the fit between its limiting block 51 and the side wall of the connecting hole 11 becomes increasingly tight, forming a self-locking effect. This greatly improves the connection stability between the ground stake rod 5 and the ground stake head, effectively preventing loosening or detachment during use. Taking a ground stake rod 5 with a rod diameter of 8mm as an example, the lower diameter d of the mating ground stake head is 8mm, and the upper diameter D is 8.5mm. During assembly, the rod of the ground stake rod 5 passes through the connecting hole 11. During continuous downward movement, the limiting block 51 of the ground stake rod 5 will gradually tighten against the wall of the trapezoidal connecting hole 11, achieving a stable and reliable connection.

[0042] <Hook Part 2>

[0043] In this embodiment, as Figure 2 As shown, the hook portion 2 extends outward and downward from the side of the connecting post 1, forming an angle α of 15~30° between the hook portion 2 and the connecting post 1. Compared to the larger angle of 45~60° in traditional designs, the smaller angle design adopted in this scheme can effectively prevent slippage when hooked with the rope, significantly improving connection reliability and operational safety, while also facilitating the effective transmission of force to the ground. An arc-shaped transition area 21 is formed below the hook portion 2, and the radius of curvature R of the arc-shaped transition area 21 satisfies 4.0mm≤R≤5.0mm to optimize stress distribution and avoid stress concentration.

[0044] like Figure 6 As shown, this design increases the side thickness t of the hook part 2 to more than 4.5mm, which greatly improves the bending and fracture resistance of the hook part 2.

[0045] like Figure 1 and Figure 2 As shown, a reinforcing structure is provided at the connection between the hook part 2 and the connecting post 1. This reinforcing structure is an arc-shaped reinforcing rib 3, which smoothly transitions between the root of the hook part 2 and the side wall of the connecting post 1. The width of the reinforcing rib 3 is 3-5mm. The load-bearing structure of the double hook parts 2 and the middle reinforcing rib 3 can effectively distribute external loads, reduce local stress, and significantly improve the overall fracture resistance, deformation resistance, and service life of the ground stake head, enabling it to withstand greater outdoor tensile forces.

[0046] Furthermore, at least one of the two hook portions 2 has a functional hole 22, such as... Figure 1 As shown, the functional hole 22 allows a fixed rope or bandage to pass through and bear force, thereby expanding the product's application functionality. This design does not limit the diameter of the functional hole 22; it only needs to be large enough for the rope or bandage to pass through and connect, and is typically designed to be 5–7 mm.

[0047] In this application, the left and right hook parts 2 adopt an asymmetrical structural design, such as Figure 2 As shown, the arc-shaped transition area 21 of the left hook portion 2 is positioned lower, closer to the bottom of the connecting post 1, while the arc-shaped transition area 21 of the right hook portion 2 is positioned higher, closer to the middle of the connecting post 1. This asymmetrical layout of the arc-shaped transition area 21 helps to optimize the stress distribution of the ground stake under non-uniform loads or inclined stress conditions, enhancing its adaptability and torsional resistance in complex usage environments.

[0048] To further enhance the fracture and deformation resistance of the hook portion 2, this design makes further improvements to the top of the connecting post 1, specifically as follows: Figure 1 and Figure 2 As shown, the top of the connecting column 1 protrudes beyond the top of the hook portion 2, and the top of the connecting column 1 extends in all directions, forming a support platform 4 on the top of the hook portion 2. This support platform 4 structure not only increases the rigidity and impact resistance of the connection, but also provides a more sufficient force-bearing surface for hammering installation.

[0049] The connecting column 1, hook part 2, arc-shaped reinforcing rib 3, and top support platform 4 in this project are manufactured using a plastic injection molding process, preferably using plastic raw materials such as polyamide (PA) and polycarbonate (PC) which have certain strength, toughness, and weather resistance. This molding process effectively ensures the overall structural integrity, dimensional consistency, and mechanical strength of the product, avoiding the weakening of strength caused by separate assembly, while improving production efficiency and product reliability.

[0050] Example 2:

[0051] This embodiment provides a tent peg head, such as Figure 7 and Figure 8 As shown, the tent includes a connecting post 1 and two hooks 2 located on its sides. The tent peg head is mushroom-shaped. The structure of the connecting hole 11 in the middle of the connecting post 1, and the method of fixing the connecting hole 11 to the tent peg rod 5 are the same as in Embodiment 1.

[0052] Example 3:

[0053] This embodiment provides a tent peg head, such as Figure 9 and Figure 10 As shown, both sides of the connecting post 1 extend outwards, with one side forming a right-angle hook portion and the other side forming a horizontal hook portion. The horizontal hook portion has a functional hole 22. The structure of the connecting hole 11 in the middle of the connecting post 1, as well as the fixing method between the connecting hole 11 and the ground nail rod 5, are the same as in Embodiment 1.
