Description

Technical Field

[0001] The utility model belongs to the technical field of anchoring devices, and in particular relates to a portable anchoring device. Background Art

[0002] Rope rappelling, as a specialized skill, involves descending from a height using specialized ropes. This skill can be particularly effective in special scenarios, such as firefighting and rescue operations, and in assault operations. A suitable anchor point and sufficient stability are crucial for ensuring the safety of the rappeller and the successful completion of the task. However, in emergency situations, finding a suitable anchor point is often difficult, and those that do meet the requirements (such as staircase handrails) are often far from the rappelling location, making it difficult to secure and extend the rope. Furthermore, the rope often needs to pass over a wall, where the wall edge constantly rubs against the rope, posing a significant safety hazard. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a portable anchoring device to solve the technical problem in the prior art that it is difficult to determine a suitable anchoring point in a short time.

[0004] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions:

[0005] A portable anchoring device includes a load-bearing frame and a folding frame body rotatably connected to the load-bearing frame, and a support structure for supporting the folding frame is provided on the load-bearing frame; the load-bearing frame includes two cross bars, and the cross bars are connected by multiple longitudinal bars. The folding frame body includes a fixed cylinder fixedly connected to the top surface of the edge longitudinal bar, and a first rotating shaft is rotatably connected in the fixed cylinder. A telescopic rod is provided on the first rotating shaft, and a cantilever rod is provided on the side of the telescopic rod facing away from the load-bearing frame. The top end of the telescopic rod is connected to the free end of the cantilever rod by a diagonal rod, and a safety hook is provided at the free end of the cantilever rod. The supporting structure includes a support rod, one end of the support rod is rotatably connected to the load-bearing frame, and the other end of the support rod is detachably connected to the telescopic rod.

[0006] Furthermore, the cross bars are parallel to each other and are connected by four longitudinal bars that are evenly spaced and perpendicular to the cross bars to form a rectangular load-bearing frame. The length of the cross bars is greater than that of the longitudinal bars.

[0007] Furthermore, the telescopic rod is located in the middle of the first rotating shaft and is perpendicular to the first rotating shaft. The telescopic rod includes a fixed rod whose bottom is fixedly connected to the first rotating shaft. The fixed rod is hollow inside and is slidably connected to the movable rod.

[0008] Furthermore, the support structure includes support units located on both sides of the telescopic rod, the support unit includes two opposite fixed blocks, the fixed blocks are welded to the upper surface of the longitudinal rod adjacent to the fixed cylinder, a second rotating shaft perpendicular to the fixed blocks is provided between the two fixed blocks, and a rotating hole adapted for the second rotating shaft is opened at one end of the support rod.

[0009] Furthermore, a hidden extension frame is provided in the supporting frame, and the extension frame includes an extension rod. The interior of the cross bar is hollow and one end away from the first rotating shaft is open. The extension rod extends into the interior of the cross bar along the opening of the cross bar and is slidably connected to the cross bar. The outer ends of the extension rods on both sides are connected and fixed by connecting rods to form a complete extension frame.

[0010] Furthermore, a walking structure is provided in the longitudinal rod below the first rotating shaft. The interior of the longitudinal rod is hollow and has right-angle notches at both ends. The walking structure includes a sliding rod slidably connected to the inner wall of the longitudinal rod. A pulley is provided on the side surface of the outer end of the sliding rod along the extension direction of the cross rod. The pulley slides inward as the sliding rod slides and can be accommodated in the right-angle notch.

[0011] Furthermore, a shoulder strap is snapped onto the bottom or side surface of the crossbar.

[0012] The beneficial effects of the present invention are:

[0013] (1) Compared with the existing technology, the folded anchoring device is small in size and light in weight, which makes it easy to carry or transport on the back. It can quickly respond to various emergency scenarios (rescue, assault, etc.) without the need to find additional anchoring points, saving time and effectively improving work efficiency.

[0014] (2) The overall structure is simple and can be quickly erected. The height of the safety hook is adjustable, which allows it to easily pass over the wall, avoiding contact and friction between the rigging and the wall, and eliminating adverse factors during the rappelling process. In addition, it can also protect the wall and prevent damage to people's property.

[0015] (3) The force on the cantilever end can be balanced by applying pressure to the load-bearing frame, and the amount of pressure applied can be adaptively adjusted, making personnel deployment more flexible.

DETAILED DESCRIPTION

[0029] Example 1, specifically as follows.

[0030] like Figure 1As shown, a portable anchoring device includes a carrying frame 1 and a folding frame body 2 rotatably connected to the carrying frame 1 , and a supporting structure 3 for supporting the folding frame body 2 is provided on the carrying frame 1 .

[0031] The supporting frame 1 includes two parallel cross bars 11, which are connected by four longitudinal bars 12 that are evenly spaced and perpendicular to the cross bars 11 to form a rectangular supporting frame 1. The length of the cross bar 11 is greater than that of the longitudinal bar 12, and both the cross bar 11 and the longitudinal bar 12 have rectangular cross-sections.

[0032] The folding frame 2 includes a fixed cylinder 21 welded to the top surface of the edge longitudinal rod 12. The fixed cylinder 21 is a hollow cylinder with open ends, and its extension direction is consistent with the extension direction of the longitudinal rod 12. In this embodiment, there are four fixed cylinders 21, spaced apart along the extension direction of the longitudinal rod 12. A first rotating shaft 22 is rotatably connected to the fixed cylinder 21. The length of the first rotating shaft 22 is consistent with the length of the longitudinal rod 12. A telescopic rod 23 is located at the center of the first rotating shaft 22, perpendicular to the first rotating shaft 22. The telescopic rod 23 includes a fixed rod 231 welded to the first rotating shaft 22 at its bottom. The fixed rod 231 is hollow and has a movable rod 232 slidably connected thereto. Both the fixed rod 231 and the movable rod 232 have rectangular cross-sections. A cantilever rod 25, perpendicular to the movable rod 232, is welded to the side of the movable rod 232 facing away from the supporting frame 1. A diagonal brace 26 connects the top of the movable rod 232 to the free end of the cantilever rod 25, forming a stable triangular structure. A safety hook 27, with an inward-facing opening, is welded to the lower surface of the free end of the cantilever rod 25. A safety latch is provided at the opening of the safety hook 27 to prevent the rigging from detaching from the safety hook 27. To further strengthen the structural strength of the support frame 2, diagonal braces 24 are welded to either side of the fixed rod 231, forming a predetermined angle with the horizontal plane. The end of the diagonal brace 24, facing away from the fixed rod 231, is welded to the outer surface of the first rotating shaft 22, forming a triangular diagonal brace structure.

[0033] When the folding frame 2 is rotated from the horizontal folding state to the vertical state, the folding frame 2 lacks support, so a support structure 3 for supporting the folding frame 2 is provided on the supporting frame 1. The support structure 3 includes support units located on both sides of the telescopic rod 23. The support unit includes two fixed blocks 31 facing each other. The fixed blocks 31 are welded to the upper surface of the longitudinal rod 12 adjacent to the fixed cylinder 21. A second rotating shaft 32 perpendicular to the fixed blocks 31 is provided between the two fixed blocks 31. A rotating hole adapted to the second rotating shaft 32 is provided at one end of the support rod 33, thereby realizing a rotational connection between the support rod 33 and the supporting frame 1. The other end of the support rod 33 away from the second rotating shaft 32 is detachably connected to the telescopic rod 23 via a second limiting mechanism 34.

[0034] The second limiting mechanism 34 includes a second limiting hole 341 extending along the direction of the second rotation axis 32 and penetrating the entire telescopic rod 23 and the supporting rods 33 on both sides. When the folding frame 2 is rotated to the vertical position, the second insertion rod 342 is inserted along the second limiting hole 341 to fix the telescopic rod 23 and the supporting rods 33 on both sides, thereby supporting the entire folding frame 2. In addition, it is worth emphasizing that in this embodiment, the movable rod 232 is provided with multiple second limiting holes 341 along its length. The telescopic rod 23 can be adjusted by adjusting the height of the movable rod 232 and inserting the second insertion rod 342 into the corresponding second limiting hole 341.

[0035] In actual use, the safety hook 27 is used to suspend the rigging. The load-bearing frame 1 requires pressure to balance the load. This typically requires one or more people standing on the load-bearing frame 1 to create pressure through their own weight. To facilitate portability, the length of the load-bearing frame 1 is limited. Therefore, a hidden extension frame 13 is provided within the load-bearing frame 1. Without changing the size of the load-bearing frame 7, the extension frame 13 provides a larger load-bearing area, facilitating the application of pressure to the load-bearing frame 1.

[0036] The extension frame 13 includes an extension rod 14 with a rectangular cross-section. The crossbar 11 is hollow and open at one end away from the first rotating shaft 22. The extension rod 14 extends into the crossbar 11 along the opening and is slidably connected to the crossbar 11. The outer ends of the extension rods 14 on both sides are connected and fixed by connecting rods 15 to form a complete extension frame 13. The outer surface of the connecting rod 15 is provided with a handle to facilitate applying force to the extension frame 13.

[0037] To adjust the extension length of the extension frame 13, two first limiting mechanisms 16 are disposed opposite each other on the inner side surfaces of the longitudinal rods 12 adjacent to the extension frame 13. The first limiting mechanisms 16 include two limiting cylinders 161 spaced apart along the extension direction of the longitudinal rods 12. The limiting cylinders 161 are spaced apart from the inner side surfaces of the longitudinal rods 12 and fixedly connected to each other via welded mounting brackets 162. A first insertion rod 163 is disposed within the limiting cylinders 161 along the extension direction of the longitudinal rods 12. First limiting holes 166 that mate with the first insertion rod 163 are formed on the inner side surfaces of the cross bar 11 and the extension rod 14. Multiple first limiting holes 166 are formed on the inner side surfaces of the extension rods 14 along their length. The first insertion rod 163 passes through the first limiting holes 166 and is inserted into the interior of the extension rods 14, thereby securing the extension frame 13. The multiple first limiting holes 166 on the extension rods 14 allow the extension length of the extension frame 13 to be adjusted.

[0038] In addition, a support ring 164 is welded to the first rod 163. Support ring 164 is positioned between the two retaining tubes 161. The outer side of support ring 164 abuts against the outer retaining tube 161, and a spring 165 is interposed between the inner side of support ring 164 and the inner retaining tube 161. During adjustment, the first rod 163 is pulled inward so that the end of the first rod 163 slides against the side of the extension rod 14. At this point, spring 165 compresses, releasing the first rod 163 and adjusting the extension frame 13. When the first retaining hole 166 on the extension rod 14 aligns with the first retaining hole 166 on the inner side of the crossbar 11, the spring 165 rebounds, causing the first rod 163 to insert into the first retaining hole 166 on the extension rod 14, thereby achieving adjustment and securing of the extension frame 13. The spring 165 and its associated structure facilitate convenient operation and improve efficiency.

[0039] A walking structure 4 is provided within the longitudinal rod 12 below the first rotating shaft 22. The longitudinal rod 12 is hollow and has right-angled notches at both ends. The walking structure 4 includes a sliding rod 41 slidably connected to the inner wall of the longitudinal rod 12. A pulley 42 is provided on the side surface of the outer end of the sliding rod 41 along the extension direction of the cross bar 11. The pulley 42 slides inwardly with the sliding rod 41 and can be accommodated in the right-angled notch. A third limiting mechanism 43 is also provided on the inner side surfaces of both ends of the longitudinal rod 12. The third limiting mechanism 43 includes a third limiting hole 431 formed on the inner side surface of the longitudinal rod 12. A limiting nut 432 is welded to the inner side surface of the longitudinal rod 12, directly opposite the third limiting hole 431. A limiting screw 433 is threadedly connected to the limiting nut 432 and passes through the third limiting hole 431 to press against the side surface of the sliding rod 41, thereby limiting the sliding rod 41 and the pulley 42, preventing the sliding rod 41 from separating from the longitudinal rod 12.

[0040] When the anchoring device reaches the predetermined position and no longer needs to be moved, loosen the limit screw 433, pull out the sliding rod 41 and rotate it until the pulley 42 is facing upward, then partially insert it into the longitudinal rod 12, lock the limit screw 433, and the remaining part of the sliding rod 41 extends out of the outer end of the longitudinal rod 12, thereby increasing the contact area between the supporting frame 1 and the ground, and also preventing the supporting frame 1 from tipping over, thereby playing a supporting role.

[0041] When the anchoring device is in the folded state, that is, the folding frame 2 and the supporting structure 3 are rotated to a horizontal state and in contact with the load-bearing frame 1, the telescopic rod 23 and the support rod 33 need to be fixed to prevent the telescopic rod 23 and the support rod 33 from tipping over during transportation and causing damage to nearby people or objects. To this end, a fixing strap 5 is clamped onto the upper surface of the longitudinal rod 12 on one side of the extension frame 13. There is one fixing strap 5 on each side, and the fixing straps 5 on both sides are connected by a buckle to secure the telescopic rod 23 and the support rod 33 inside. The buckle structure also facilitates the locking or loosening of the fixing strap 5.

[0042] The bottom or side of the crossbar 11 is connected to a shoulder strap 6, which allows the anchoring device to be carried manually for quick transfer. In addition, the entire anchoring device is made of high-strength and lightweight materials (such as aluminum alloy, magnesium alloy, etc.), which not only has strong working performance but also is light in weight and easy to carry.

[0043] When in use, first carry the anchor device on your back or move it to the predetermined location via the walking structure 4, then lay the entire anchor device flat. When there is a wall (such as a window sill, balcony, parapet, etc.), place the anchor device close to the inner side of the wall, that is, the first rotating shaft 2 is parallel to the wall and close to the wall foot. Then, open the buckle and rotate the folding frame 2 to a vertical state. If the cantilever rod 25 is not high enough, the movable rod 232 can be stretched until the cantilever rod 25 is above the wall. At this time, the folding frame 2 is supported by the supporting structure 3 and the movable rod 232 in the telescopic rod 23 is limited. In addition, the sliding rod 41 is pulled out and flipped over until the pulley 42 is facing upward, then reinserted and fixed in place by the third limiting mechanism 43. Finally, the extension frame 13 can be selectively pulled out, and pressure (human weight) is applied to the supporting frame 1 and the extension frame 13. The safety hook 27 hangs the rigging to complete the installation of the entire anchor device.

[0044] The foldable portable anchoring device has the following advantages: firstly, the folded anchoring device is small in size and light in weight, which makes it easy to carry or carry on the back. It can quickly respond to various emergency scenarios (rescue, assault, etc.) without having to find additional anchoring points, saving time and effectively improving work efficiency; secondly, the overall structure is simple and can be quickly erected, and the height of the safety hook is adjustable, which can easily pass over the wall, avoiding contact and friction between the rigging and the wall, and eliminating adverse factors in the rappelling process; in addition, it can also protect the wall and prevent damage to people’s property; thirdly, the force on the cantilever end can be balanced by applying pressure to the load-bearing frame, and the amount of pressure applied can be adaptively adjusted. The anchoring point is more stable and can effectively protect the personal safety of the rappelling personnel.

[0045] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
