Abstract
Description
Technical Field
[0001] The invention relates to a fire escape fixed anchor Background Art
[0002] In the current existing technology, when firefighters enter a fire building to carry out fire extinguishing and relief tasks, once they are trapped by the fire and thick smoke in the building, the escape route is blocked by fire and smoke. Firefighters can only save themselves by escaping from the outside of the building through the window. It is difficult to find a fixing point for the escape rope. Iron pipes and other objects are used to fix the escape rope. This type of fixing method is extremely unsafe and often causes accidents. American firefighters use the structure of a ship anchor to fix it by the window. For houses with wooden structures, the anchor tip can be embedded in the window frame and is not easy to slip during use. When used in houses with cement tile walls, the anchor tip is prone to sliding. There are hidden dangers in its reliability and safety during use, resulting in firefighters not daring to use this anchor for human body support escape when escaping outside a brick-concrete structure building.
[0003] The purpose of the present invention is to design a fire escape fixed anchor which is light to carry, safe, reliable and quick to operate. The fixed anchor can be used in conjunction with a constant speed descender to complete the escape function outside the building when firefighters are trapped during fire fighting and rescue in high-rise buildings. Summary of the invention
[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme, which is characterized in that: the escape fixing anchor is composed of an outer card plate assembly, an inner card plate assembly, and a nut handle, wherein the outer card plate assembly is composed of a splint assembly, a support rod assembly, a steel pipe, and a screw, and the splint assembly is composed of a splint, a folding card plate, and a movable card plate. The folding card plate is positioned between the two splints by a rotating shaft and a limit column and can rotate. The other end of the folding card plate is fixed with a movable card plate by bolts. The movable card plate has multiple holes, and the fixed position of the movable card plate can be adjusted for clamping and positioning of walls near different windows. The contact surfaces of the splint, the folding card plate, and the movable card plate with the wall are provided with sharp teeth, and the splints in the splint assembly are welded to the steel pipe and fastened as one. The steel pipe is tightly connected with the end of the screw rod by a fixing pin, and the fixing pin passes through the steel pipe and the screw and is welded and fastened. A support rod assembly is set at one end of the steel pipe near the sharp teeth of the clamp assembly. One end of the support rod assembly is welded with a round tube, which is used to be set on the steel pipe and can rotate. A flat plate is welded on the other end of the support rod assembly, and a rubber plate is bonded on the flat plate for supporting the window sill horizontal surface. The support rod assembly is limited on the steel pipe by a retaining spring and cannot move axially. A positioning screw is installed on the round tube of the assembly, which is used to screw into the opening on the steel pipe to limit the rotation of the support rod assembly when in use. The above components constitute the outer clamp assembly. The inner clamp assembly is welded by a clamp assembly, a long steel pipe, a sleeve, and a hook piece. The clamp assembly is welded on the outer end of the long steel pipe, and the hook piece is welded on one end of the sleeve. The sleeve is welded together by two sections of steel pipes and can be tightly sleeved on the long steel pipe. It is positioned by screws, and the sleeve can be removed or connected according to different wall thicknesses. The assembly is mounted on the screw rod through a long steel tube and a sleeve, and can be moved axially and adjusted according to the thickness of different walls. A limiting column is welded on one side of the outer end of the long steel tube, and the inner end of the positioning column extends into the guide groove of the screw rod to limit the rotation of the inner card assembly, which is convenient and quick to install. When in use, the sharp teeth of the two card assemblies are opposite, and the two card assemblies clamp the wall from the outside to the inside, and rotate the handle of the screw cap installed on the screw rod to clamp the vertical wall of the window sill. The rubber plate on the flat plate under the support rod of the outer card assembly is supported on the horizontal surface of the window sill, and the installation of the escape anchor is completed. Then the safety hook of the constant speed descent device is hung into the round hole of the hook piece to escape.
[0005] The escape anchor weighs only about 2.5 kilograms and can be folded and carried. It has a load-bearing capacity of more than 1,000 kilograms and can withstand a 100-kilogram impact test at a height of 1 meter. The escape anchor can also simplify the splint assembly into a single plate part directly welded to the steel pipe to reduce its weight. BRIEF DESCRIPTION OF THE DRAWINGS
