Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without making creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a fire hose winding mechanism, including dolly frame 1, 1 bottom both sides of dolly frame are equallyd divide and are do not connected with frame 5, four top departments of two frames 5 are rotated through the pivot respectively and are connected with dolly gyro wheel 4, 1 front side top parallel arrangement of dolly frame has last compression roller 6 and lower compression roller 7, all be fixed with on two frames 5 with last compression roller 6 and down compression roller 7 rotate the vertical support pole 51 of being connected, 5 tops of two frames are equallyd divide and do not rotate through axis of rotation 21 and are connected with hand wheel 2.
Wherein, the setting of hand wheel 2, a manual operation for the user, when driving axis of rotation 21 through hand wheel 2, horizontal plate 22 and activity bolt 23 rotate, accessible activity bolt 23 drives the wraparound of fire hose between two activity bolts 23 and rotates, the setting through last compression roller 6 and lower compression roller 7 again, make the fire hose before the rolling, receive the extrusion between last compression roller 6 and the lower compression roller 7, so that extrude the water of persisting in the fire hose, make the fire hose shakeout simultaneously, avoid the fire hose to produce the fold in extrusion process.
