Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to fire fighting equipment technical field especially a multifunctional fire fighting wrench. BACKGROUND
[0002] The fire hydrant is mainly used for the fire truck to take water from the municipal water supply pipe network or outdoor fire water supply pipe network to implement fire extinguishing, and can be directly connected with the water hose and the water gun to discharge water for fire extinguishing.
[0003] The existing outdoor fire hydrant cap and the water suction pipe cap are opened by the fire hydrant wrench, but the fire hydrant wrench is only limited to opening and closing the outdoor fire hydrant cap and the water suction pipe cap of specific models and specified sizes, and cannot be opened when the model of the fire hydrant wrench does not match, so it is necessary to carry multiple tools or use other tools to open, and the more tools are lost or not found at the critical moment, and it is not convenient to carry and use, which is not fast and is not conducive to the rescue at the fire scene, consumes the valuable time of fire rescue, and causes irreparable loss of life and property. SUMMARY
[0004] The utility model provides a kind of multifunctional fire fighting wrench to solve the problem that the existing fire hydrant cap and water suction pipe cap need to carry multiple different tools to operate when opening, closing, repairing and overhauling.
[0005] In order to solve the technical problem, the utility model adopts the following technical scheme: a multifunctional fire fighting wrench, comprising a fire hydrant wrench, the fire hydrant wrench comprising an open wrench, an inner five-angle sleeve and a wrench body, the inner five-angle sleeve and the open wrench being arranged at the front end of the wrench body, a pipe wrench being arranged at the tail end of the wrench body, and a sleeve assembly being fixedly arranged on the wrench body.
[0006] Further, the sleeve assembly comprises a sleeve rod and a sleeve head, and the two ends of the sleeve rod are respectively provided with the sleeve head.
[0007] Further, the two ends of the sleeve rod are provided with an inner hexagonal hole, and the outer hexagonal head of the sleeve head is inserted into the inner hexagonal hole, so as to mount the sleeve head on the sleeve rod.
[0008] Further, the sleeve assembly is connected to the wrench body by a bolt assembly.
[0009] The utility model has the advantages that the pipe wrench and the sleeve assembly are arranged on the fire hydrant wrench, so that the single-function fire hydrant wrench has other functions, the sleeve assembly can replace the sleeve head according to actual needs, and only a small amount of tools are needed to open, close, repair and maintain the outdoor fire hydrant cap and the water suction pipe cap, which is convenient to carry, has high work efficiency and is conducive to the rescue at the fire scene, so as to save time and effort.BRIEF DESCRIPTION OF DRAWINGS BRIEF DESCRIPTION OF DRAWINGS
