A kind of pull-type fuel tank burglar alarm, including peace are disclosed in the patent that application publication number is 104786828 B of CN
Mounted in the oil box theft-proof cap of fuel tank oral area, and it is fitted in the lock core that Security for fuel tank covers, it is characterised in that: the Security for fuel tank
The lower part of lid is equipped with antitheft lifting component in reservoir port, and the upper end of the antitheft lifting component connects under oil box theft-proof cap
Portion, the lower end of the antitheft lifting component are installed on the junction of fuel tank and reservoir port in the lower part of reservoir port.
The present invention is compared with existing fuel tank burglar alarm adds antitheft lifting component, by antitheft lifting component thoroughly by oil box theft-proof cap with
Fuel tank is packed in an entirety, on the one hand solves the problems, such as extraneous turning power theft, while also solving asking for sled side theft
Topic.But it has the following disadvantages: that stealer can destroy again by damage at the top of antitheft lifting component after lock core, so that antitheft lifting group
Part sinks to fuel tank internal, and the insertion fuel tank internal of oil pipe steathily is carried out oil steathily, and anti-theft is not comprehensive, can not still have after device destruction
Effect guarantees the anti-theft of fuel tank.
A kind of automobile oil tank anti-theft filtering oil filler is disclosed in the patent that application publication number is 208085484 U of CN,
Including oil filler body, integrally formed with flange platform, the flange platform is equipped with the first threaded hole, false spiral shell for the upper end of the oil filler body

The pollution of nozzle and device covers sealing cover 3 after the completion of refueling, and sealing rubber pad 32 can effectively increase antitheft fixing seat
2, the leakproofness between sealing cover 3 and oil fuel tube 11, reduce leaking gasoline, when stealer want to 1 internal petrol of automotive oil tank into
When row is stolen, because of the antitheft fixing seat 2 and oil fuel tube 11 being obliquely installed, stealer can not be realized antitheft fixation by visual impact
It is split type structure between seat 2 and oil fuel tube 11, subconsciousness can select to loosen simulation nut 24 or open the implementation of sealing cover 3 to steal
It steals, when nut 24 is simulated in stealer turn, annular pressure sensor 26 senses that simulation nut 24 loosens, and single-chip microcontroller 35 incudes
Change to pressure signal, so that alarm device 37 sounds an alarm, draws back stealer with fear, while radio receiving transmitting module 38 is sent a signal to
User's mobile phone terminal, achievees the purpose that anti-theft warning, and after the power supply of stealer breaking plant, electromagnetic plate 271 is powered off, sliding block
231 under the rebound effect of the first spring 272 in 27 internal slide of telescopic cavity, drive annular strip 23 to stretch out, so that stealing
When person pulls antitheft fixing seat 2, annular strip 23 can be effectively stuck in inside automotive oil tank 1, locked, avoided to oil fuel tube 11
Antitheft fixing seat 2 is removed and is stolen by stealer, oily steathily when stealer, which opens sealing cover 3, will steal in oil pipe insertion oilhole
Pipe is stopped by antitheft oil screen 4, effectively avoid steathily oil pipe contacted with gasoline, avoid stealer from being stolen, when stealer will rush
It hits in part insertion oilhole when hitting antitheft oil screen 4, the oil strain plug 43 of arcuate structure can effectively reduce impulse member and oil strain plug 43
Contact area, and impact force is reduced under the effect of the elastic force of second spring 442, the damage of antitheft oil screen 4 is reduced, stealer is avoided
It is stolen, after impulse member impact force is excessive, and oil strain plug 43 is caused to damage, the oil strain plug 43 that is damaged under impulse member active force
The first filtering screen 45 impact sloping baffle 46 is squeezed, so that 46 stress of sloping baffle pushes, so that the inclination gear being staggered
Plate 46 forms an air-tight state, thoroughly shuts antitheft oil screen 4, is effectively ensured after antitheft oil screen 4 damages to the anti-of automotive oil tank 1
The property stolen, further avoiding stealer steals 1 internal petrol of automotive oil tank, so that 1 inside vapour of automotive oil tank be effectively ensured
The anti-theft of oil after antitheft oil screen 4 damages, can control electromagnetic plate 271 to be powered, so that annular strip 23 retracts in telescopic cavity 27
Portion removes antitheft fixing seat 2 and replaces to antitheft oil screen 4, is effectively convenient for the lasting use of device, reduces the replacement of device
Cost increases the service life of device.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, as long as the change in spirit of the invention, to embodiment described above
Change, modification will all be fallen in scope of the presently claimed invention.
