Description

Technical Field

[0001] This utility model belongs to the field of fire safety technology, specifically relating to a gravity hook for fire protection. Background Technology

[0002] In fire and rescue operations, it is often necessary to create fire rescue anchors or fire escape anchors to assist in rescue work. Fire escape anchors are fixed points set inside or outside a building to secure fire escape ropes or other rescue equipment, providing assistance for personnel escape or rescue and reducing the risk of injury or death. They are typically created by driving anchor nails into the target location, or by securing or wrapping ropes, webbing, or other equipment to a sturdy object. This point serves as a fixed point for hoisting, lowering, and establishing rescue systems. They are widely used in mountainous areas, high-rise buildings, and deep wells, as well as in firefighter training. However, this method of construction is inconvenient and cannot effectively guarantee safety, posing certain risks and hindering its effective use in fire and rescue operations. Utility Model Content

[0003] The purpose of this utility model is to provide a gravity hook for firefighting to solve the problems of inconvenience and safety hazards of traditional fire rescue anchor points.

[0004] The technical solution of this utility model is: a gravity hook for fire fighting, including two hooks, two first connecting members and two second connecting members. The hooks are inverted L-shaped. A through hole is opened horizontally on the straight section of the hook. A thread is provided in the through hole. A threaded bar is detachably provided in the through hole. The straight sections of the two hooks are arranged facing each other inward. The ends of the vertical sections of the hooks are connected to the first connecting members. The two first connecting members are arranged crosswise and are rotatably connected to each other by a first bolt. The ends of the first connecting members and the ends of the second connecting members are rotatably connected to a hanging plate by a third bolt. The hanging plate has a hanging hole.

[0005] As a further improvement of this utility model, a spring is provided between the first bolt and the third bolt.

[0006] As a further improvement of this utility model, a wear-resistant and anti-slip pad is provided on the inner wall of the hook.

[0007] The beneficial effects of this utility model are as follows: This utility model provides firefighters with a stable operating platform and convenient portability during rescue operations. In use, by pressing the scraper upwards, a rhomboid shape is formed between the two second connecting pieces and the two first connecting pieces. This causes the first connecting pieces to open the hooks, allowing the two inverted L-shaped hooks to be secured at the desired suspension position. Threaded rods can also be inserted into the through holes of the two hooks to create effective anchor points. Finally, the hooks can be suspended and hoisted through the hanging holes to facilitate rescue operations.

[0008] The first connecting piece, which is arranged in a cross pattern, can increase the overall stability and support of the device. It is held in place by two inverted L-shaped hooks and connected by bolts. The weight of the suspended object itself is used to generate a downward force to clamp the hooks when the device is in use. Thus, the heavier the object, the stronger the suspension force of the device.

[0009] Springs make compression easier and also have a buffering and shock-absorbing effect, absorbing vibration and impact energy and improving the stability and reliability of equipment; wear-resistant and anti-slip pads can increase friction, reduce damage caused by friction, thereby protecting the service life of components and improving work efficiency.

[0010] This utility model has the advantages of simple structure, low manufacturing cost, convenient portability and mobility, strong practicality and applicability to various places and environments. It lays the foundation for enhancing the combat effectiveness of firefighters' rescue operations and plays a very important role in various building structures and rescue sites. It provides firefighters with a stable operating platform and convenient portability, which greatly ensures the safety of fire and rescue personnel. Attached Figure Description

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] like Figure 1As shown, a fire-fighting gravity hook includes two hook parts 1, two first connecting parts 2, and two second connecting parts 4. The hook parts 1 are inverted L-shaped. A through hole 7 is opened horizontally on the straight section of the hook part 1. A thread 8 is provided in the through hole 7. A threaded bar is detachably provided in the through hole 7. The straight sections of the two hook parts 1 are arranged opposite each other with their inward sides. The vertical ends of the hook parts 1 are connected to the first connecting parts 2. The two first connecting parts 2 are arranged crosswise and are rotatably connected to each other by a first bolt 31. The ends of the first connecting parts 2 and the ends of the second connecting parts 4 are rotatably connected by a second bolt 32. The other ends of the two second connecting parts 4 are rotatably connected to a hanging plate 5 by a third bolt 33. The hanging plate 5 has a hanging hole 6.

[0015] A spring 10 is provided between the first bolt 31 and the third bolt 33; a wear-resistant and anti-slip pad 9 is provided on the inner wall of the hook 1.

[0016] The components used in this invention are made of high-strength materials, such as aluminum alloy or stainless steel, to ensure that the anchor points formed by this device can withstand a certain weight and tension, thereby ensuring the safety of escaped personnel and achieving the goal of safety and reliability.

[0017] In positions with protrusions or crossbeams, two inverted L-shaped hooks 1 are secured to the protrusions or crossbeams. Threaded rods are inserted into the through holes 7 of the two hooks 1, connecting them to form a stable anchor point. Using other tools, items or personnel are suspended and hoisted through the hanging holes 6. During use, the weight of the suspended object generates a downward force, causing the connection between the first connector 2 and the second connector 4 to move inwards. The rhombus formed by the first connector 2 and the second connector 4 gradually closes, tightening the hooks 1. The heavier the object, the stronger the suspension force of the device. After use, the threaded rods are removed. By pressing the hanging plate 5 upwards, combined with the upward pressure provided by the spring 10, the connection between the first connector 2 and the second connector 4 moves outwards, gradually opening the rhombus. This causes the first connector 2 to open the hooks 1, allowing them to disengage from their locked position and the device to be removed.

[0018] In the absence of a suitable hanging location, such as on the windowsill of a window or balcony, a hole can be drilled by inserting a drill bit into the through hole 7. The through hole 7 can limit the drilling position, thereby forming a hole. Then, threaded rods are inserted into the through holes 7 of the two hooks 1 to connect them, thereby forming a stable anchor point for subsequent work.

[0019] This utility model is highly practical and has a wide range of applications. In fire rescue operations in high-rise buildings, it can form fire escape anchor points to provide safe escape routes for people, help trapped people to save themselves or wait for rescue, and provide firefighters with a stable operating platform and convenient portability. In earthquake rescue operations, it can also be quickly fixed to collapsed buildings, making it convenient for rescuers to enter the ruins to carry out rescue operations, greatly ensuring the safety of fire rescue personnel.
