As an embodiment of the present invention, as shown in fig. 4, a floating plate 52 is movably connected inside the oil storage chamber 5, a floating rod 521 is fixedly connected to an outer surface of an upper end of the floating plate 52, a through hole is formed in a center position of the cover plate 51, the floating rod 521 passes through the through hole, and scales are formed on an annular outer surface of the floating rod 521, wherein the floating rod 521 is made of an elastic material.

Through adopting above-mentioned technical scheme, the oil mass of the inside lubricating oil of oil storage chamber 5 is not convenient for the user to observe, in operation, the through-hole is seted up on apron 51 surface, the inside rubber pad that is equipped with of through-hole, prevent that the rainwater from getting into oil storage chamber 5 along stock 521, stock 521 and kickboard 52 fixed connection, kickboard 52 floats on the lubricating oil surface, and stock 521 appears the change of displacement along with the change of the oil mass of the inside lubricating oil of oil storage chamber 5, the user judges the volume of lubricating oil through observing the scale, avoid lubricating oil because of do not in time add the condition that can't carry out timely lubrication to grip block 22, thereby guarantee the holistic continuous operation effect of the device, stock 521 that the elastic material constitutes avoids apron 51 to break when opening.

The working principle is as follows: when the fire hydrant main body 1 starts to be used, the baffle plate 4 inside the water outlet 2 is impacted by water flow to force the baffle plate 4 to move forwards, the clamping block 22 inside the telescopic groove 21 is pushed backwards through the lever 3 movably connected inside the connecting groove 24, so that the sealing performance of the connection between the water hose and the water outlet 2 is improved, the rotating shaft part of the lever 3 can be wrapped by the rubber film 241 fixedly connected to the outer surface of the lever 3, the phenomenon that the rotating shaft is corroded due to moisture and cannot provide power for the clamping block 22 to clamp the water hose connector is prevented, a user adds lubricating oil into the oil storage cavity 5, the lubricating oil inside the oil storage cavity 5 lubricates the clamping block 22, the motion resistance of the clamping block 22 is reduced, the operation effect of the device is improved, the water flow pushes the baffle plate 4 to move forwards, at the moment, the lever 3 rotates through the rotating shaft, the first extension block 32 and the second extension block 33 respectively extend outwards inside the first extension groove 31 and the second extension groove 34, the overall length of the lever 3 is changed, so that the lever 3 can effectively provide power for the displacement of the clamping blocks 22, because the lever 3 takes the rotating shaft as a parting line, the length of one side of the two levers 3 close to the blocking plate 4 is greater than the length of one side close to the two clamping blocks 22, when the blocking plate 4 is displaced and the lever 3 rotates, the movement distance of the blocking plate 4 is greater than the movement distance of the clamping blocks 22, the acting force of the lever 3 on the clamping blocks 22 is greater than the impact force of water flow on the blocking plate 4, so that the clamping effect of the clamping blocks 22 on the water band is improved, the sealing performance of the water band and the water outlet 2 is improved, the sliding groove I25 is formed in the inner surface of the water outlet 2, the baffle 36 is forced to move along the sliding groove I25 through the sliding block 38 when the lever 3 is turned, and in order to avoid the overlarge gap between the baffle 36 and the connecting groove 24, the rotating wheel 37 moves along the sliding groove II 35 when the lever 3 is turned, therefore, the baffle 36 is always parallel to the first sliding groove 25, meanwhile, the sliding block 38 and the first sliding groove 25 are both in a T-shaped structural design, higher stability can be provided during sliding, water flow can be effectively prevented from being damaged by the rubber film 241 through the baffle 36, so that the rotating shaft cannot be contacted with water, the lever 3 can continuously provide power for displacement of the clamping block 22, the clamping effect of the clamping block 22 on the water belt and the water outlet 2 is ensured, a user can drip lubricating oil into the oil storage cavity 5, the clamping block 22 moves forwards under the pushing force generated when being stretched by the telescopic spring 23, the blocking block 221 fixedly connected with the upper end of the clamping block 22 is perpendicular to the clamping block 22 and is inserted into the guide groove 211 to push the oil conveying plate 53 to move forwards to be inserted into the oil storage cavity 5, the lubricating oil submerges the oil conveying hole 55, when the clamping block 22 moves backwards, the blocking block 221 moves backwards along the guide groove 211, the oil conveying plate 53 loses the resisting function, the oil conveying plate 53 moves backwards under the pushing of the extrusion spring 54 until the oil conveying hole 55 is communicated with the telescopic groove 21 to enable lubricating oil in the oil conveying hole to drip onto the surface of the clamping block 22, the lubricating oil is coated by the coating brush 58 when the clamping block 22 reciprocates along the telescopic groove 21, so that the running resistance of the clamping block 22 in the telescopic groove 21 is reduced, meanwhile, the probability of corrosion of the clamping block 22 is reduced by coating the lubricating oil, the service life of the device is further prolonged, when the oil conveying plate 53 is pushed by the blocking block 221 to be inserted into the oil storage cavity 5, the first sealing gasket 56 on the outer surface of the rear end of the oil conveying plate 53 contacts with the inclined plane of the second sealing gasket 57 on the side along with the increase of the pushing force of the blocking block 221, the sealing effect is increased, and when the oil conveying plate 53 moves backwards under the elastic force generated by the extrusion spring 54, the first sealing gasket 56 on the outer surface of the front end of the oil conveying plate contacts with the inclined plane of the second sealing gasket 57 on the side, the sealing property of the oil delivery groove 59 and the oil delivery plate 53 is ensured by the backward thrust applied to the oil delivery plate 53 by the pressing spring 54, thereby reducing the loss of the lubricating oil, prolonging the lubricating effect of the lubricating oil on the clamping block 22, indirectly prolonging the service life of the device, arranging a through hole on the surface of the cover plate 51, arranging a rubber pad in the through hole to prevent rainwater from entering the oil storage cavity 5 along the floating rod 521, fixedly connecting the floating rod 521 with the floating plate 52, floating the floating plate 52 on the surface of the lubricating oil, and the floating rod 521 has displacement change along with the change of the oil quantity of the lubricating oil in the oil storage cavity 5, so that a user can judge the quantity of the lubricating oil by observing the scales, the situation that the clamping block 22 cannot be lubricated in time due to untimely addition of the lubricating oil due to dryness is avoided, thereby ensuring the overall continuous operation effect of the device, and the floating rod 521 made of elastic material prevents the cover plate 51 from being broken when being opened.
