Description

The automatic protecting air hose

Affiliated technical field

The utility model relates to a kind of automatic protecting air hose.

Background technique

At present, the use popularity rate of China resident family combustion gas is more and more higher, combustion gas brings numerous simultaneously also dangerous constantly easily securities of the lives and property of people to people, now because various security incidents such as the gas leakage that the use combustion gas causes, poisoning, fire, blast are also increasing.Although on market, also occurred some security personnel's products of developing out at flexible pipe safety at present, but these products all exist the defective that can not be ignored: what have has introduced solenoid valve in structure, its structure is complexity but also impracticable not only, in case do not had electricity will lose all protection functions; What have only can report to the police when the gas leakage accident takes place and can not cut off source of the gas automatically.00234322.3 number Chinese patent provides a kind of " automatic protecting gas hose ", in use also there is following defective in it: the one, introduced thin security personnel's spring as hair, so thin spring, behind the expanding-contracting action that certain number of times takes place, be easy to take place deformation, spring force and also bigger change can take place, thereby influence security personnel's performance of product greatly, even lose whole protection functions.The 2nd, the reset operation inconvenience needs very big jacking force could realize resetting.

Summary of the invention

In order to overcome common security personnel's gas hose complex structure in the prior art, reset operation inconvenience, problem that reliability is lower, the utility model provides a kind of automatic protecting air hose, this automatic protecting air hose simple in structure, reset operation convenient, safe and reliable, the effect that has energy-saving and environmental protection concurrently.

The technological scheme that its technical problem that solves the utility model adopts is: comprise interconnective tube body and security department, one end of tube body and security department is provided with connecting head, it is characterized in that security department comprises body, sealed cap, slide bar and positioning seat, slide bar is movably arranged in the positioning seat, sealed cap is fixed on slide bar one end and matches with the sealing surface of body, the other end of slide bar is provided with location piece, is provided with the slide block that matches with slide bar in the body, the outer setting of the body slip magnet ring relative with slide block.

Slide bar overcoat security personnel spring, the two ends of security personnel's spring lean respectively on sealed cap and positioning seat.

One side of slip magnet ring is provided with Returnning spring, and positioning seat is provided with perforate.

The pneumatic tube two ends of tube body are withheld by the bag sheet and are connected on the body, connecting head is made of rubber interface cover, intermediate plate and locking nut, rubber interface cover sticks on the body, and intermediate plate and locking nut are arranged on the rubber interface and overlap an end, and locking nut clamps rubber interface cover by intermediate plate.

The utility model is by above-mentioned specific design, can significantly reduce that the gas transmission leather hose comes off because of taking place when using combustion gas, aging cracking, the security incident of breaking etc. and to cause, and do not need any external force and power supply supply, also can cut off source of the gas immediately automatically even trickle gas leakage takes place, have the advantage of simple in structure, easy to assembly, long service life, energy-saving and environmental protection, good reliability in gas transmission leather hose (pipeline) section.

Description of drawings

Below in conjunction with drawings and Examples detailed content of the present utility model is described.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of positioning seat.

As shown in the figure, the utility model comprises interconnective tube body 1 and security department 2, pneumatic tube 14 two ends of tube body 1 are withheld by bag sheet 15 and are connected on the body 4, one end of tube body 1 and security department 2 is provided with connecting head 3, connecting head 3 is made of rubber interface cover 16, intermediate plate 17 and locking nut 18, rubber interface cover 16 sticks on the body 4, and intermediate plate 17 and locking nut 18 are arranged on the rubber interface and overlap 16 1 ends, and locking nut 18 clamps rubber interface cover 16 by intermediate plate 17.Security department 1 comprises body 4, sealed cap 5, slide bar 6 and positioning seat 7, slide bar 6 is movably arranged in the positioning seat 7, positioning seat 7 is provided with perforate 19, sealed cap 5 is fixed on slide bar 6 one ends and matches with the sealing surface 8 of body 4, the other end of slide bar 6 is provided with location piece 9, be provided with the slide block 10 that matches with slide bar 6 in the body 4, slide block 10 can adopt magnetic material, body 4 is outer to be provided with the slip magnet ring 11 relative with slide block 10, one side of slip magnet ring 11 is provided with Returnning spring 13, slide bar 6 overcoats security personnel spring 12, the two ends of security personnel's spring 12 lean respectively on sealed cap 5 and positioning seat 7.Under user mode, connecting head 3 connects source of the gas and burner respectively, and when locking nut 18 precessions, each intermediate plate 17 can tighten up to the hose connection direction of axis line simultaneously, with the bore of rubber interface cover 16 press from both sides littler and littler, folder is tight more more, reaches the gastight purpose of firm connection easily.Under normal circumstances, the combustion gas perforate 19 from body 4, positioning seat 7 freely, again through the last burners that arrive of pneumatic tube 14.Combustion gas can be by magnetic field magnetisation through magnetic slider 10 and slip magnet ring 11 positions the time, the combustion gas micel can be become more even by refinement atomizing, molecules align, thereby raising combustion efficiency, make fuel gas buring more abundant, reduced discharge of harmful gases effectively, both played energy saving, effect that again can the clean environment.If because of aging cracking takes place in gas transmission leather hose (pipeline), break, the gas leakage that comes off etc. and cause, then pneumatic tube 14 1 sides can be because of obtaining from body 4 enough gas make-up that the perforate 19 the other and positioning seat 7 is come through sealed cap 5 (owing to the restriction of sealed cap 5 in moment, the peak rate of flow that flows into pneumatic tubes 14 from body 4 just also has only or is slightly larger than the required peak rate of flow of gas range normal combustion), the air pressure that is directed at pneumatic tube 14 1 sides is die-offed, and the air pressure in the body 4 does not almost have change in a flash at this, the pressure that makes sealed cap 5 overcome security personnel's spring 12 moves rapidly and tightly is attached on the sealing surface 8 of body 4, thereby be implemented in the automatic source of the gas that cuts off of moment, reach the automatic protecting purpose.After finding and getting rid of the gas leakage accident, only with hand promotes slip magnet ring 11, slip magnet ring 11 drives the end of magnetic slider 10 pushing tow slide bars 6, sealed cap 5 and sealing surface 8 are broken away from, gas in the body 4 can enter pneumatic tube 14 rapidly, make the pneumatic tube 14 and the gas pressure of body 4 reach balance again, recover normal air feed again.
