[0024] The specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.
[0025] First embodiment
[0026] See also Figures 1 to 4As shown, a fixing device for a hammock includes a connecting frame 1, a rope ring 2 and a fixing mechanism 3, the rope ring 2 is fixedly arranged at the bottom of the connecting frame 1, the fixing mechanism 3 is arranged at the top of the connecting frame 1, the fixing mechanism 3 includes an adjusting component 4 and a clamping component 5, the adjusting component 4 includes a movable frame 6 and an adjusting member 7, two movable frames 6 are provided, and are symmetrically arranged and respectively arranged at both ends of the connecting frame 1, the adjusting member 7 is used to adjust the distance between the two movable frames 6, the clamping component 5 includes a movable clamping block 8 and an anti-slip pad 9, two movable clamping blocks 8 and two anti-slip pads 9 are each provided, and the two movable clamping blocks 8 are respectively rotatably arranged at the top of the corresponding movable frames 6, the movable clamping block 8 is provided with a clamping groove 10 with a circular arc structure, and the inner sides of the clamping grooves 10 of the two movable frames 6 are provided with through grooves 11 distributed in an interlaced manner, and the two anti-slip pads 9 are respectively fixed in the corresponding clamping grooves 10.
[0027] Specifically, the movable frame 6 includes a sliding seat 12, a first hinge rod 13, a second hinge rod 14, and a hinge seat 15. A horizontal slide groove 16 is provided at the top of the connecting frame 1. The bottom of the sliding seat 12 is slidably connected to the slide groove 16. The bottom of the first hinge rod 13 is rotationally connected to the top of the sliding seat 12. The top of the first hinge rod 13 is slidably connected to the bottom of the second hinge rod 14. The top of the second hinge rod 14 is rotationally connected to the bottom of the hinge seat 15. The top of the hinge seat 15 is rotationally connected to the side of the movable clamping block 8. The rotation axis between the first hinge rod 13 and the sliding seat 12 is parallel to the rotation axis between the hinge seat 15 and the movable clamping block 8, and the rotation axis between the first hinge rod 13 and the sliding seat 12 is perpendicular to the rotation axis between the second hinge rod 14 and the hinge seat 15.
[0028] To use the device, first place it near the target tree trunk. Using the adjustment member 7, adjust the spacing between the two movable frames 6 so that they drive the sliding seat 12 to slide within the sliding groove 16 of the connecting frame 1, thereby changing the initial distance between the two movable clamping blocks 8. Next, rotate the articulated seat 15 about the second hinge rod 14 to align the openings of the two clamping grooves 10 with the tree trunk. Next, bring the device closer to the tree trunk, positioning it within the two clamping grooves 10. Once again, rotate the articulated seat 15 about the second hinge rod 14 to align the openings of the two clamping grooves 10 with the movable clamping blocks 8. Then, operate the adjustment member 7 again to loosen the spacing between the two movable frames 6, thereby tightening the movable clamping blocks 8 toward the center of the tree trunk. At this point, the anti-slip pads 9 contact the tree trunk through the inner walls of the clamping grooves 10, providing friction. Because the clamping grooves 10 are arc-shaped and the through-slots 11 are staggered, the two movable clamping blocks 8 can adapt to changes in the thickness of the tree trunk during tightening, tightly wrapping the trunk through the elastic deformation of the anti-slip pads 9. Finally, the hammock rope is passed through the rope ring 2 and fixed, and the hammock is stably suspended by the clamping force of the fixing mechanism 3.
[0029] In outdoor environments, the ground is often uneven, and trees grow at varying angles. By rotating the first hinged rod 13 and the sliding seat 12, and the hinged seat 15 and the movable clamping block 8, the tilt angle of the connecting frame 1 can be adjusted. This allows the fixture to flexibly adapt to varying terrain and tree trunk tilts, ensuring the hammock is always properly suspended. This prevents the hammock from tilting or becoming unstable due to ground or tree trunk tilt, expanding the device's applicability in a variety of complex outdoor scenarios.
[0030] At the same time, by properly adjusting the hammock's tilt angle, the force applied to the hammock can be more evenly distributed, preventing the fixing device from loosening or the hammock from being damaged due to excessive local force. At the same time, it can also prevent the user from slipping due to excessive tilt of the hammock, effectively reducing safety risks and ensuring the user's personal safety during use.
[0031] In addition, during the actual installation process, if the tree trunk position is not ideal or the hammock hanging height is not appropriate, there is no need to readjust the position of the fixing device on the tree trunk. The top of the first hinged rod 13 and the bottom of the second hinged rod 14 can be slid together to achieve fine-tuning of the hammock position and height, simplifying the installation process, saving installation time and effort, and improving installation efficiency.
[0032] Specifically, the working principle of this embodiment is as follows: when using the hammock fixing device, first place the device next to the target tree trunk. The adjusting member 7 drives the two movable frames 6 to slide along the slide grooves 16 at both ends of the connecting frame 1, changing the initial spacing of the movable clamping blocks 8 to adapt to the thickness of the tree trunk. Next, the angle of the movable clamping blocks 8 is adjusted by rotating the hinge seat 15 and the second hinge rod 14 so that the opening of the clamping groove 10 is aligned with the tree trunk. After the device is brought close to the tree trunk, the hinge seat 15 is rotated again to close the clamping groove 10. Subsequently, the adjusting member 7 is operated again to narrow the spacing between the movable frames 6. The movable frames 6 drive the movable clamping blocks 8 to tighten toward the center of the tree trunk. At this time, the arc-shaped clamping grooves 10 cooperate with the staggered through grooves 11, combined with the elastic deformation of the anti-slip pads 9, to tightly fit the surface of the tree trunk. After the hammock rope is passed through the rope ring 2 and fixed, if the ground is uneven or the tree trunk is tilted, the tilt angle of the connecting frame 1 can be flexibly adjusted by rotating between the first hinged rod 13 and the sliding seat 12, and the hinged seat 15 and the movable clamping block 8; if the position and height of the hammock need to be fine-tuned, the sliding cooperation between the top of the first hinged rod 13 and the bottom of the second hinged rod 14 can be used to achieve it, ultimately ensuring that the hammock is firmly suspended.
[0033] By coordinating the adjustment component 4 with the clamping component 5, it can adapt to tree trunks of different thicknesses, solving the problem of fixed size of traditional devices; the tilt angle adjustment function enables it to adapt to complex terrain and trunk tilt conditions. Whether it is a slope, uneven ground or irregularly grown trees, it can be stably installed, greatly expanding the use scenarios.
[0034] At the same time, the anti-slip pad 9 and the arc-shaped clamping groove 10 enhance friction to prevent the hammock from shaking and falling off; reasonable adjustment of the tilt angle can optimize the force distribution of the hammock, prevent local overload from causing loosening of the fixing device or damage to the hammock, reduce the risk of users slipping, and ensure all-round safety of use.
[0035] In addition, the hammock position and height can be fine-tuned without reinstalling, simplifying the installation process and saving time and energy; the quick adjustment design makes outdoor setup easier, especially suitable for activities such as camping and hiking that require frequent changes of venues, improving user experience and installation efficiency.
[0036] Second embodiment
[0037] Based on the first embodiment, the top of the first hinge rod 13 is provided with a sliding hole 17, and the bottom of the second hinge rod 14 is slidably connected to the sliding hole 17. The movable frame 6 also includes a locking rod 18. The side of the first hinge rod 13 is provided with a positioning hole 19 that communicates with the sliding hole 17. The side of the second hinge rod 14 is provided with a plurality of through holes 20, which are evenly spaced along the axis of the sliding hole 17. The locking rod 18 is inserted into the positioning hole 19 and the corresponding through holes 20. The outer side of the locking rod 18 is provided with an external thread, and the positioning hole 19 is provided with an internal thread that threadably connects to the locking rod 18.
[0038] When adjusting the position and height of the hammock, the sliding hole 17 at the top of the first hinge rod 13 and the bottom of the second hinge rod 14 allow for flexible adjustment of the position of the movable frame 6. Once the position is adjusted to the desired level, the locking rod 18 is inserted sequentially through the positioning hole 19 on the side of the first hinge rod 13 and the corresponding through-hole 20 on the side of the second hinge rod 14. The external threads on the outside of the locking rod 18 are screwed into the internal threads in the positioning hole 19 to securely connect the first hinge rod 13 and the second hinge rod 14. This prevents the position of the movable frame 6 from being shifted due to external forces, ensuring the stability of the hammock's fixed position.
[0039] Third embodiment
[0040] Based on the first embodiment, the adjusting member 7 includes an adjusting screw 21, which is rotatably disposed horizontally within the slide slot 16. A screw hole is defined on the side of the sliding seat 12, which is threadedly engaged with the adjusting screw 21. The adjusting screw 21 has two symmetrically arranged threaded segments with opposite spiral directions, and the screw holes of the sliding seats 12 in the two movable frames 6 are threadedly engaged with the corresponding threaded segments.
[0041] When the adjusting screw 21 is rotated, its two symmetrically arranged threaded segments, running in opposite directions, engage with the screw holes on the sides of the two sliding seats 12. As the adjusting screw 21 rotates, the two sliding seats 12 synchronously slide in opposite directions within the chute 16, thereby moving the movable frame 6 closer or further apart, precisely adjusting the spacing between the two movable clamping blocks 8. This threaded transmission allows for fine-tuning of the spacing, allowing the movable clamping blocks 8 to fit snugly on tree trunks of varying thicknesses.
[0042] Fourth embodiment
[0043] In accordance with the third embodiment, the adjusting member 7 further includes an adjusting handwheel 22, which is rotationally coupled to the connecting frame 1 and coaxially fixedly connected to the adjusting screw 21. The user rotates the adjusting handwheel 22, causing the adjusting screw 21 to rotate within the chute 16. The larger diameter of the handwheel provides greater operating torque, easing rotation of the adjusting screw 21 and, in turn, driving the sliding seat 12 to slide within the chute 16, thereby adjusting the spacing between the movable frames 6.
[0044] Fifth embodiment
[0045] In addition to the third embodiment, the adjusting member 7 further includes an adjusting motor 23, which is fixedly connected to the connecting frame 1. The output end of the adjusting motor 23 is coaxially fixedly connected to the adjusting screw 21. When the adjusting motor 23 is activated, the output end of the adjusting motor 23 rotates the adjusting screw 21. The adjusting screw 21, through threaded transmission, drives the sliding seat 12 to slide within the slide slot 16, automatically adjusting the distance between the two movable frames 6. The adjusting motor 23 can be operated via a control switch or remote controller, precisely controlling the opening and closing of the movable clamp 8 according to the thickness of the tree trunk and usage requirements.
[0046] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
