Detailed Description

Referring to fig. 1-4, the present utility model provides the following technical solutions: including protecting sheathing 1, the storehouse 11 of ventilating has been seted up in the protecting sheathing 1, two connecting holes 12 that are used for connecting tube way have been seted up to protecting sheathing 1 lateral wall, the torsional spring board 121 that corresponds with one of them connecting hole 12 has been articulated to storehouse 11 inner wall of ventilating, touch switch 2 is installed to connecting hole 12 inner wall, connecting hole 12 lateral wall fixedly connected with touch piece 122, touch piece 122 and touch switch 2 one end contact, install the time delay 21 that corresponds with touch switch 2 on the protecting sheathing 1, electromagnetic chuck 22 that corresponds with time delay 21 is installed to protecting sheathing 1 inner wall, protecting sheathing 1 inner wall sliding connection has the shutoff board 3 that is used for carrying out shutoff to the gas, shutoff board 3 top fixedly connected with limiting plate 31, install the sliding block 4 that is used for spacing to limiting plate 31 in the protecting sheathing 1, sliding block 4 and time delay 21 function match.

In this embodiment: the protective housing 1 supports and protects each subassembly of device, the storehouse of ventilating 11 is torsional spring plate 121 and the gas of passing through is stepping down, two connecting holes 12 are the passageway of gas business turn over, when using the gas, the torsional spring plate 121 breaks with pressure balance between the gas equipment, the gas is with torsional spring plate 121 jack-up, torsional spring plate 121 self torsional spring dynamics is less than the promotion of gas, when the gas used, torsion spring plate 121 drives touch block 122 upset return, touch block 122 extrudees touch switch 2 and triggers, touch switch 2 gives out the instruction to time delay 21, time delay 21 is time delay electrical apparatus, can control the signal that touch switch 2 transmitted and give electromagnetic chuck 22 again for electromagnetic chuck 22 after the instruction, thereby make sliding block 4 no longer carry out spacingly to limiting plate 31, limiting plate 31 is spacing and bearing structure to the top of shutoff plate 3, when sliding block 4 no longer is spacing to limiting plate 31, the shutoff plate 3 is carried out the shutoff to the storehouse space, thereby it causes the gas leakage problem to forget to carry out the time to forget to open the valve to the gas, avoid the gas to cause the problem that the gas is leaked out for some time to the time is long time to the valve is out to the door is opened.

The inner wall of the ventilation bin 11 is fixedly connected with a clamp and a plate 13, and the plugging plate 3 is inserted into the inner wall of the clamp and the plate 13; the clamping plate 13 and the plugging plate 3 are matched with each other, the plugging plate 3 is inserted into the inner wall of the clamping plate 13, the middle parts of the clamping plate 13 and the plugging plate 13 are provided with clamping grooves corresponding to the plugging plate 3, and sealing plugging can be achieved.

The protective shell 1 is internally provided with a driving bin 14, a limiting plate 31 is slidably connected to the inner wall of the driving bin 14, the top end of the limiting plate 31 is fixedly connected with a driving spring 32 and a T-shaped pull rod 33, the top end of the driving spring 32 is fixedly connected to the inner wall of the driving bin 14, and the T-shaped pull rod 33 penetrates through the top end of the protective shell 1; the driving bin 14 provides a movement space for the limiting plate 31, the driving spring 32 and the T-shaped pull rod 33, when the sliding block 4 does not limit the plugging plate 3, the driving spring 32 pushes the limiting plate 31 to slide downwards, the limiting plate 31 drives the plugging plate 3 and the T-shaped pull rod 33 to slide downwards, when gas is wanted to be used, the T-shaped pull rod 33 drives the limiting plate 31 and the plugging plate 3 to slide upwards by pulling the T-shaped pull rod 33 to slide upwards, so that the plugging plate 3 does not clamp the clamping plate 13 with the clamping plate 13 any more to seal the gas, the bottom end of the sliding block 4 is in an inclined state, and when the sliding block 31 rises, the sliding block 4 can be extruded to slide to the inner wall of the protective shell 1 through the inclined bottom end of the sliding block 4, so that the limiting plate 31 can pass through the sliding block 4, and the sliding block 4 limits the limiting plate 31 again, so that preparation is made for the next security work.

The time delay device 21 is connected with the electromagnetic chuck 22 through a connecting wire 23, one end of the sliding block 4 is fixedly connected with a steel plate 41 corresponding to the electromagnetic chuck 22, and the steel plate 41 is contacted with one side of the electromagnetic chuck 22; the connecting wire 23 is a power supply and data instruction connecting piece, the delayer 21 controls the electromagnetic chuck 22 through the connecting wire 23, and the electromagnetic chuck 22 generates magnetic attraction for energizing, so that the electromagnetic chuck 22 can attract the steel plate 41, the steel plate 41 can drive the sliding block 4 to slide towards the electromagnetic chuck 22, and the delayer 21 controls the electromagnetic chuck 22 to be disconnected after working.

The bottom end of the sliding block 4 is rotationally connected with a plurality of balls 42, the balls 42 are slidably connected to the inner wall of the protective shell 1, and the top end of the sliding block 4 is fixedly connected with a limiting block for limiting the sliding block 4; the sliding block 4 drives the balls 42 to slide on the inner wall of the protective shell 1 during sliding, and the balls 42 reduce friction resistance between the sliding block 4 and the protective shell 1, so that the electromagnetic chuck 22 can conveniently drive the steel plate 41.

The working principle and the using flow of the utility model are as follows: when people last use gas, the gas promotes torsion spring plate 121 to drive and touch briquetting 122 upset, torsion spring plate 121 drives and touch briquetting 122 upset return after the use, touch briquetting 122 extrudees to touch press switch 2 and trigger, touch press switch 2 sends the instruction to time delay 21, time delay 21 carries out the time delay to trigger electromagnet 22, electromagnet 22 attracts steel sheet 41 after being controlled, thereby make steel sheet 41 can drive slider 4 to electromagnet 22 direction slide, make slider 4 no longer carry out spacingly to limiting plate 31, drive spring 32 promotes limiting plate 31 and slides downwards, limiting plate 31 drives shutoff plate 3 and T type pull rod 33 and slides downwards, shutoff plate 3 is pegged graft into card and board 13 inner wall, shutoff plate 3 cuts off the room of ventilation storehouse 11, thereby to the shutoff of gas passageway, avoid some people to forget to close the gas valve of going into for a long time, the gas valve is opened for a long time not, if because the problem that pipeline connection ageing or other problems lead to the gas leakage cause the potential safety hazard.
