[0033] Reference Figures 1 to 7A foldable hammock includes a hammock fabric 100, a connecting structure 200, a plurality of supporting structures 300 for supporting the ground, and a plurality of linkage structures 400 for supporting the hammock fabric 100. The end surface of the supporting structure 300 for supporting the ground faces the ground plane, and the end surface is provided with anti-slip grooves 310 to improve the stability of the hammock under different ground conditions, ensure that the supporting structure 300 firmly grips the ground, and provide a safe resting environment for users. Several of the supporting structures 300 and several of the linkage structures 400 are symmetrically distributed and hinged on both sides of the connecting structure 200. The linkage structure 400 is hinged to the supporting structure 300 on the same side, and the supporting structure 300 on the same side can be driven to complete the unfolding or folding by controlling the linkage structure 400. The structure realizes the rapid unfolding and compact folding of the hammock through the sophisticated mechanical structure linkage design, meeting the diverse needs of users in outdoor activities. The connecting structure 200 includes two groups of split structures 210 that are hinged to each other and arranged in mirror images. The split structures 210 are provided with branch handles 211 on one side of the facing surface. The branch handles 211 of the two groups of split structures 210 are combined into a main handle 201 when the connecting structure 200 is fully unfolded. This structure makes the folded hammock occupy a smaller area and the overall structure more compact.

[0034] In actual operation, the user only needs a few simple steps to complete the construction and adjustment of the hammock. First, unfold the connecting structure 200 so that the sub-handle 211 is combined into the main handle 201. Then, the user holds the main handle 201 with one hand and unfolds the linkage structure 400 located on both sides of the connecting structure 200 with the other hand. The linkage structure 400 drives the supporting structure 300 to unfold, thereby realizing the overall unfolding of the folding hammock.

[0035] Furthermore, in order to enhance the stability and weather resistance of the hammock when used outdoors, the support structure 300 and the linkage structure 400 are made of high-strength lightweight materials, such as aluminum alloy or reinforced plastic. In addition, the surface of the support structure 300 can be specially treated, such as sandblasting or anodizing, to improve corrosion resistance and wear resistance and extend service life.

[0036] In the present utility model, the linkage structure 400 includes a hooking rod 410, on which a first sliding sleeve 420 is mounted, and a plurality of support links 430 are hinged on the first sliding sleeve 420 for one-to-one hinge connection with the support structure 300 on the same side of the linkage structure 400; the hooking rod 410 is provided with a plurality of positioning holes 413 along its length direction, and the first sliding sleeve 420 is provided with a positioning member 421 capable of cooperating with the positioning holes 413. The combination of the hooking rod 410, the first sliding sleeve 420, and the support link 430 forms a flexible and reliable transmission system, which ensures a smooth transition of the entire mechanism during the unfolding and folding process. And by selecting a suitable positioning hole 413, the user can quickly adjust the height or tilt angle of the hammock according to actual needs, thereby increasing the convenience and comfort of use.

[0037] Specifically, the hook rod 410 is a telescopic rod structure including an outer tube 412 and an inner tube 411, and the positioning hole 413 is provided on the outer tube 412. The outer tube 412 is provided with a slide groove 414, and the first slide sleeve 420 is provided with a slide pin 422 corresponding to the slide groove 414. This design ensures that the hook rod 410 can be smoothly adjusted and locked when it is telescopic. The inner tube 411 is equipped with a mounting seat 440 and a second slide sleeve 450, the mounting seat 440 is installed at the end of the inner tube 411, and the second slide sleeve 450 is installed on the inner tube 411. The mounting seat 440 is provided with an empty slot 441, and the hammock fabric 100 is provided with a hanging rope 110 at the end of its length direction, the hanging rope 110 passes through the empty slot 441 and is connected with a buckle 120 at the end, and the buckle 120 is connected and assembled with the second slide sleeve 450. The inner tube 411 is provided with a plurality of adjustment holes 415 along its length direction, and the second sliding sleeve 450 is provided with positioning pins 451 for cooperating with the adjustment holes 415 for positioning, so that the user can conveniently adjust the hammock fabric 100 .

[0038] Furthermore, the hook rod 410 is arc-shaped, and has an arc J when the hook rod 410 is fully unfolded, and the arc J has an arc of 0.61~0.79rad. After the foldable hammock is fully unfolded, the angle α between the hook rods on both sides of the connecting structure 200 is 135°~155°. The hook rod 410 can be made of high-strength lightweight materials, such as aviation aluminum or carbon fiber composite materials, which not only ensures its stability and durability under load-bearing conditions, but also takes into account portability, so that users can easily carry and install it during outdoor activities. The role of the arc design is that it can evenly distribute the pressure applied to the surface of the hammock to maintain good balance and stability, thereby improving the user's sleeping comfort.

[0039] Taking into account the needs of users in different environments, the hammock fabric 100 is made of high-density nylon or polyester fiber material. This type of material not only has good air permeability and quick-drying properties, but also can effectively block ultraviolet radiation and protect users from the sun. The fabric is designed to be a double-layer or multi-layer structure, with a microporous mesh material embedded in the middle, which not only enhances the load-bearing capacity, but also improves the ventilation effect during sleep, making long-term rest more comfortable. The support structure 300 has an arc segment L, and the arc segment L has an arc of 0.2~0.3 rad. This design is conducive to the compact structure of the foldable hammock after folding, and can make the contact area between the support structure and the ground smaller to ensure the stability of the foldable hammock.

[0040] In particular, the utility model is also provided with a sun visor 500, and the sun visor 500 is provided with an end block 510 at the end in the length direction thereof. The mounting seat 440 is equipped with a pulling shaft above the empty slot 441, and both ends of the pulling shaft pass through the mounting seat 440 and are equipped with a locking trigger 442 at the end. The pulling shaft is equipped with a clamping block 443 for clamping the end block 510 on the part located in the empty slot 441, and the matching mechanism of the pulling shaft and the locking trigger 442 makes the installation and adjustment of the sun visor 500 simple and quick. Preferably, the sun visor 500 includes a sunshade cloth surface 501, and the edge of the sunshade cloth surface 501 is fixed by a hard frame strip 502, and the hard frame strip 502 not only reinforces the shape of the sun visor 500, but also facilitates installation and disassembly.

[0041] Furthermore, the rigid frame strip 502 is made of a light and tough material, such as reinforced plastic or aluminum alloy, to ensure that while improving the structural stability, it does not cause excessive burden to the user, and is also convenient for handling and storage after long-term use. The connection between the frame strip and the sunshade cloth surface 501 is achieved by high-strength sewing technology or a special fixing clip, which not only ensures the reliability of the connection, but also avoids wear and tear in strong winds or frequent use, thereby extending the overall service life of the sun visor 500. The material of the sunshade cloth surface 501 is preferably a sun-proof fabric with a high-density weaving process. This fabric can effectively block ultraviolet penetration and protect human skin from ultraviolet damage, while maintaining good air permeability and reducing the stuffiness caused by long-term shading. A variety of options can be provided for the cloth color design. Users can choose the most suitable color matching of reflectivity and heat absorption performance according to personal preferences or actual application scenarios (such as seaside, desert areas or urban environments) to achieve the best sunshade effect.
