All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

As shown in figures 1 to 4 of the drawings,

a fire fighting device comprises a water inlet pipe 2, a water gun 3, a ball valve 4, a storage plate 5 and a storage piece 7, wherein the water gun 3 is connected with the water inlet pipe 2 through a water hose 6; the ball valve 4 is arranged on the water inlet pipe 2, and the ball valve 4 is provided with a rotating shaft 41; the object placing plate 5 can rotate around the first axis A-A and can rotate between a first position and a second position, and the object placing plate 5 is in transmission connection with the rotating shaft 41 of the ball valve 4 and is used for driving the rotating shaft 41 to rotate; the storage part 7 is arranged on the storage plate 5, and the water gun 3 is arranged on the storage part 7 and is in plug-in fit with one end of the storage part 7; wherein, when the object placing plate 5 is positioned at the first position, the ball valve 4 is closed, and when the object placing plate 5 is positioned at the second position, the ball valve 4 is opened.

In this application, when operating personnel pulls squirt 3, can make the thing board 5 of putting together rotate around first pivot 41 to make and put thing board 5 and remove to second position department from first position, can drive the rotation synchronous rotation on ball valve 4 through putting thing board 5 in the removal process, thereby make ball valve 4 opened by the linkage, do not need the action of carrying out extra pivoted valve, and because squirt 3 has been connected with hosepipe 6, hosepipe 6 is connected with inlet tube 2, when putting thing board 5 and being located the second position, extract squirt 3 from storing piece 7, the quick travel is put out a fire the operation of putting out a fire, after putting out a fire the operation and accomplishing, only need to push back to first position department again putting thing board 5, with ball valve 4 reclose can.

In the present application, the ball valve 4 is a prior art, and the rotation shaft 41 can be rotated to control the opening or closing of the ball valve 4.

The advantage of this application is obvious, in the operation in-process, only need operate squirt 3, namely, pulling squirt 3 and attached change put the position state of thing board 5, automatic play water, and efficiency is high, in the operation in-process of putting out a fire, need not to take over, open the operation such as ball valve 4, any person can all use.

As shown in fig. 1, 2 and 4, in the actual installation process, the first axis A-A is preferably arranged to be perpendicular to the gravity direction, in the first position, the object placing plate 5 is configured to be approximately parallel to the gravity direction, in the second position, the object placing plate 5 is configured to be formed to be an acute angle with the gravity direction, and the angle α is preferably 15-80 °, and the design is beneficial in that after the external force is applied to the object placing plate 5, the object placing plate 5 can change the position of the object placing plate 5 through self gravity, so that the object placing plate 5 can be automatically moved from the first position to the second position, and even a person with smaller force can easily open the fire fighting device to perform fire extinguishing operation.

When the object placing plate 5 moves from the first position to the second position, the position of the water gun 3 can also move from a position higher than the ground to a position lower than the ground, and the water gun 3 can be pulled out of the object storage conveniently.

In some cases, the fire hydrant is not used for a long time, and the runner on the traditional fire hydrant can be opened only by spending larger force due to the smaller force arm, but in the application, the runner forms a lever principle through the object placing plate 5, and in the process of turning the object placing plate 5, the runner is matched with the gravity of the runner and the external force applied by an operator, so that the ball valve 4 is opened more easily. In this embodiment, the hose 6 is a fire hose, although other soft hoses may be used instead.

Specifically, as shown in fig. 1 and 4, the object placing plate 5 is provided with a plurality of hanging rods 8 which are arranged at intervals along the horizontal direction, the hanging rods 8 are positioned near the upper end of the object placing plate 5, the water hose 6 is hung on the hanging rods 8, and when the object placing plate 5 moves to the second position, the water hose 6 can fall off from the hanging rods 8.

In this application, can hang the hosepipe 6 in proper order with the mode of hanging in proper order and establish on peg 8, when putting thing board 5 and remove to the second position, hosepipe 6 can rely on self gravity, drops automatically from hanging the pipe and fall subaerial, and the operation personnel is when dragging squirt 3 and remove, hosepipe 6 can be comparatively light by dragging, has reduced hosepipe 6 in dragging the possibility of knotting moreover.

In this embodiment, six hanging rods 8 are provided on the storage plate 5, and the spacing distances between adjacent hanging rods 8 are consistent.

Further, since the water belt 6 is hung on the hanging rod 8, after the external force is applied to the object placing plate 5, the object placing plate 5 drives the rotating shaft 41 of the valve to rotate by means of the gravity of the water belt 6 and the object placing plate 5, so that the valve can be opened.

This application is compared in traditional fire hose that draws in with the mode of coiling, and this application only needs to hang the hosepipe 6 in proper order and establish on peg 8 at the in-process that hangs, then only needs the length that every hosepipe 6 of process dangled downwards keep approximately always can. That is, the fire hose can be divided into a plurality of parts to be hung when the fire hose is folded, so that the fire hose is more convenient and easier to fold.

Moreover, the fire hose formed by the traditional coil has the inner diameter of 19mm which is the common diameter of the fire hose, but in the application, after the fire hose is placed in a hanging mode, the inner diameter of the fire hose can be 40mm, 50mm or even 65 mm.

The application is not limited to being mounted on a wall, but can also be mounted on a fire engine.

Preferably, as shown in fig. 1, 2 and 4, the hanging rod 8 is linear, and the hanging rod 8 is approximately perpendicular to the surface of the storage plate 5. Preferably, the hanging rod 8 is perpendicular to the surface of the object placing plate 5, and the linear hanging rod 8 can reduce the possibility that the water belt 6 still hangs on the hanging rod 8 when the object placing plate 5 reaches the second position. Of course, in the practical application process, the hanging rod 8 may be alternatively used, so long as the water belt 6 can be detached from the hanging rod 8 when the object placing plate 5 moves to the second position.
