Detailed Description

The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.

As shown in fig. 1 to 6, an auxiliary tool for facilitating opening of an indoor fire hydrant cabinet comprises a hemispherical metal shell 1, a fireproof rubber suction cup 4 is arranged at the bottom of the hemispherical metal shell 1, the hemispherical metal shell 1 is provided with a hemispherical cavity, the hemispherical cavity is communicated with the cavity of the fireproof rubber suction cup 4, and a handle 3 is hinged to the back of the hemispherical metal shell 1; a passage structure which can be opened and closed is arranged between the handle 3 and the hemispherical metal shell 1.

The general working principle is as follows: when the handle 3 is perpendicular to the hemispherical metal shell 1, the channel structure is closed, and when the fireproof rubber sucker 4 is pressed on the door of the fire brush, the fireproof rubber sucker 4 adsorbs the door of the fire hydrant box because the fireproof rubber sucker 4 is flexible and the pressure in the cavity of the fireproof rubber sucker is lower than the external atmospheric pressure; when handle 3 rotated certain angle along hemisphere metal-back 1, access structure opened, the chamber of fire-resistant rubber sucking disc 4 was linked together with the external world, and unable absorption that produces breaks away from on the fire hydrant chamber door, the separation of realization and fire hydrant chamber door of being convenient for fire-resistant rubber sucking disc 4.

In the scheme, as shown in fig. 1 and 3, a double-lug seat 2 is fixed on the back of a hemispherical metal shell 1, and a handle 3 is hinged with the double-lug seat 2 through a rotating shaft 5; the handle 3 is fixedly connected with the rotating shaft 5.

In order to enable the fire-resistant rubber suction cup 4 to be quickly removed from the door of the fire-fighting brush, as shown in fig. 5, the channel structure is: comprises a telescopic rod 6, a spring 8 and a rotating block 9; each ear of the double-ear seat 2 is provided with an inner cavity 10 and a shaft hole through which the rotating shaft 5 passes, the rotating shaft 5 passes through the inner cavity 10 and is in clearance fit with the shaft hole, and a rotating block 9 is fixed on the rotating shaft 5 positioned in the inner cavity 10; a sliding hole is formed between the inner cavity 10 and the hemispherical cavity of the hemispherical metal shell 1, a telescopic rod 6 is arranged in the sliding hole at a gap, the telescopic rod 6 is provided with a plug 7 for plugging the sliding hole, and a spring 8 is sleeved on the telescopic rod 6; when the rotating block 9 rotates a certain angle, the rotating block abuts against the telescopic rod 6 so as to jack the plug 7 out of the sliding hole, so that the hemispherical cavity of the hemispherical metal shell 1 is communicated with the inner cavity 10, and the inner cavity 10 is communicated with the outside through a gap between the shaft hole and the rotating shaft 5.

In order to ensure that the hemispherical cavity of the hemispherical metal shell 1 can be well communicated with the inner cavity 10, the telescopic rod 6 is in a spline rod shape, and meanwhile, the sliding hole is a unthreaded hole.

In order to enable the telescopic rod 6 to move to realize the opening and closing of the sliding hole, the plug 7 is arranged on the end of the telescopic rod 6 positioned in the hemispherical cavity of the hemispherical metal shell 1; the end of the telescopic rod 6 positioned in the inner cavity 10 is provided with a ball head 601, and the spring 8 is sleeved on the telescopic rod 6 between the ball head 601 and the inner wall of the inner cavity 10.

In this embodiment, the rotating block 9 is tapered, and when the handle 3 is at the upper position or the lower position, the tip of the rotating block 9 abuts against the ball 601.

In this embodiment, the sliding hole opening at the hemispherical cavity of the hemispherical metal shell 1 is in a wide opening shape, the plug 7 is adapted to the wide opening, and the plug 7 is fixed on the telescopic rod 6 through a screw.

In this embodiment, an annular groove is formed in the annular end surface of the hemispherical metal shell 1, and the refractory rubber suction cup 4 is embedded in the annular groove and screwed down by a screw. And the diameter of the fire-resistant rubber suction cup 4 is kept consistent with the diameter of the annular end surface at the bottom of the semicircular metal shell 1 in order to apply pressure.

When the fire-resistant rubber suction cup 4 is attached to the door of the hydrant cabinet, a protrusion 401 is further provided outside the wear-resistant rubber suction cup 4 for further consideration of detachment. The hand can also separate the refractory rubber suction cup 4 from the hydrant cabinet door by the protrusion 401.

When the conflagration breaing out, the appurtenance of this scheme is handed, lets fire-resistant rubber sucking disc 4 and fire hydrant chamber door contact, lets handle 3 perpendicular and hemisphere metal casing 1 press to the chamber door simultaneously, lets fire-resistant rubber sucking disc 4 inhale on the chamber door, then toward pulling out handle 3 outward, can open the chamber door.

When the other fire hydrant box door needs to be opened, the fire-resistant rubber suction cup 4 needs to be taken down from the previous fire hydrant box door, and the fire-resistant rubber suction cup can be taken down by rotating the handle 3 upwards or downwards. When the handle 3 is rotated upwards or downwards, the end of the rotating block 9 is abutted against the ball head 601, and the telescopic rod 6 moves so as to separate the plug 7 from the sliding hole. Outside air enters the inner cavity 10 through a gap between the shaft hole and the rotating shaft and then enters a hemispherical cavity of the hemispherical metal shell 1 through a gap between splines on the telescopic rod 6, and the hemispherical cavity is communicated with a cavity of the fireproof rubber sucker 4, so that the cavity of the fireproof rubber sucker 4 is communicated with the outside atmosphere, the pressure is the same, and the fireproof rubber sucker is convenient to take down.
