Description

TECHNICAL FIELD

[0001] The utility model relates to fire fighting equipment technical field especially a kind of quick connecting device and fire fighting water suction pipe for fire fighting water suction pipe. BACKGROUND

[0002] Fire fighting water suction pipe is the key component in fire water supply system, and the interface of fire fighting water suction pipe is the key position to ensure the smooth and efficient operation of the whole water suction operation.

[0003] The existing threaded interface fire fighting water suction pipe is generally used to connect vehicle and outdoor fire hydrant, pump adapter, which needs two people to cooperate and use special external wrench to connect. In the connection process, only the water suction pipe wrench can be used for tightening connection due to double-person operation. There is a problem that special external wrench cannot be clamped and clamped accurately. In the seconds-saving fire extinguishing scene, valuable time and physical strength are wasted, which brings complexity to rescue task. SUMMARY

[0004] The utility model provides a kind of quick connecting device and fire fighting water suction pipe for fire fighting water suction pipe, can quickly connect fire fighting water suction pipe, save time and effort, without using special external wrench again.

[0005] In order to solve the technical problem, the utility model adopts the following technical scheme:

[0006] Firstly, the application provides a kind of quick connecting device for fire fighting water suction pipe, including clamp, the handle is installed at the opening of clamp, the handle is installed on the limit connecting piece on the two outer sides of clamp opening, and a circle of antiskid pad is arranged on the inner side of clamp.

[0007] Further, one side of the handle is provided with a threaded segment, and the other side is a non-threaded segment.

[0008] Further, the limit connecting piece is a nut, and the limit connecting piece fixes and limits the handle and the clamp.

[0009] Further, the antiskid pad is fixed on the clamp by adhesion, and the adhesion connection is convenient for replacing the damaged antiskid pad.

[0010] Secondly, the application provides a kind of fire fighting water suction pipe, including hose, the threaded joint is connected at the two ends of hose, and the quick connecting device is fixed on threaded joint.

[0011] The utility model has the advantages that: the utility model sets handle on clamp, and the clamp is fixedly connected with fire fighting water suction pipe, the handle is rotated to realize connection by hand, time is saved, and the effect of saving labor is achieved, without using special external wrench again, and the problem that special external wrench cannot be clamped and clamped accurately is overcome. BRIEF DESCRIPTION OF DRAWINGS

[0012] Figure 1 It is a structural schematic view of the utility model;

[0013] Figure 2 It is a use schematic view of the utility model and the fire water suction pipe;

[0014] Figure 3 It is Figure 2 The enlarged view of A.

[0015] In the drawing: 1. clamp, 2. handle, 201. threaded end, 202. non-threaded end, 3. limiting connecting piece, 4. anti-skid pad, 5. fire water suction pipe. DETAILED DESCRIPTION

[0016] The technical scheme in the embodiments of the utility model will be described clearly and completely in connection with the drawings in the embodiments of the utility model.

[0017] Reference Figures 1 to 3 A kind of quick connecting device for fire water suction pipe, including clamp 1, handle 2 is installed at the opening of clamp 1, handle 2 is installed on the limiting connecting piece 3 of two outer sides of the opening of clamp 1, a circle of anti-skid pad 4 is arranged on the inner side of clamp 1.

[0018] Further, one side of the handle 2 is provided with a threaded end 201, and the other side is a non-threaded end 202.

[0019] Further, the limiting connecting piece 3 is a nut, which fixes and limits the handle 2 and the clamp 1.

[0020] Further, the anti-skid pad 4 is fixed on the clamp 1 by adhesion, and the adhesion connection is convenient for replacing the damaged anti-skid pad 4.

[0021] The application also provides a fire water suction pipe, which comprises a hose, threaded joints are connected to two ends of the hose, and the quick connecting device is fixed on the threaded joints.

[0022] Working principle: when using, the handle at the opening of the clamp is loosened, the clamp is placed at the threaded joint of the fire water suction pipe, and then the opening of the clamp and the handle are tightened by the nut, so that the clamp and the fire water suction pipe are integrated, and when using, only the threaded joint needs to be rotated by holding the handle, so that the connection can be realized.

[0023] Through the above description, those skilled in the art can make simple changes and modifications without deviating from the scope of the technical concept of the utility model, which should fall within the protection scope of the utility model.
