Abstract

The utility model relates to a safe oil-stolen preventing box cover which belongs to a safe device and is formed by a box cover, a collar, a screen pipe and a screen stencil. The collar and an oiling pipe orifice are sleeved together with a gap; the upper opening of the oiling pipe orifice and the box cover are in screw lock connection and matched with each other, and the lower opening thereof is connected with the screen pipe; a screen stencil seal is arranged at the lower end of the screen pipe; a screen stencil takes the shape of a flat plate; an oil tank lock is inserted into a round hole on the cover plate of the box cover; a ratchet pawl is fixed at the lower end of the lock lever of the oil tank lock; the box cover and the oiling pipe orifice are matched and fixed through screw lock; the lock lever and the ratchet pawl are embedded into the circumferential groove on the inner wall of the oiling pipe orifice through rotation; a back plate tightly fixed with the oil tank lock through a screw cap is arranged on the inner surface of the box cover; and a channel flow for communication of the circumference of the back plate and the round hole is formed on the inner plane surface of the back plate. The utility model has the beneficial effects that the structure is simple, the use is convenient, oil overflow and stealing can be effectively prevented, and various oil loss caused by oil stealing is reduced. In addition, the channel flow is designed on the back plate, so that the oil tank has good air permeability, high security, and the like.

Description

The safe antitheft fuel lid

Affiliated technical field

The utility model relates to a kind of anti-joyride device, especially the safe antitheft fuel lid.

Background technology

The oil-receptacle of automobile is exactly a fuel tank, and the Oiltank structure of automobile also has a variety of, and mounting means is mainly exposed and built-in.General large-scale passenger and freight car, the Sheng oil mass is more, and it all is exposed installing.But expose fuel tank owing to there is not anti-joyride device, oil plant is easy to stolen.Oil is stolen, and not only brings very big economic loss, and causes the walking along the street difficulty.In order to address these problems, driver's bright lock handle fuel tank cap lock commonly used is on casing, but bright lock easily smashes by the oil stealer, and safety is relatively poor.For this reason, the cylindrical drum that has wire net simple in structure that also has the people once to design to install on hydraulic fluid port can't enter oil suction pipe, but because it is simple in structure, steel wire Netease is destroyed, steals oily person and still can easy to do oil plant be stolen, and still can not improve safety.In addition, existing fuel lid is owing to unreasonable structure, and permeability to air is poor, causes internal pressure bigger, and pressure can't be drained, and deposits potential safety hazard, thus need provide a kind of safety very high anti-joyride device, to solve the stolen damnous problem of oil plant.

Summary of the invention

Cause problems such as oil plant easily is stolen at existing fuel tank poor stability, the utility model provides a kind of safe antitheft fuel lid, advantages such as it is rational in infrastructure, easy to use, good permeability, safety height.

Safe antitheft fuel lid of the present utility model, be to constitute by case lid, box cupling, screen casing and screen cloth, the alternate crack with the oiling mouth of pipe of box cupling intussusception fuses, suitable for reading and the case lid of oiling mouth of pipe spiral shell mutually links and connects cooperation, the end opening of the oiling mouth of pipe has connected screen casing, the lower end of screen casing has screen cloth to seal, and described screen cloth is plate shaped.

As further improvement of the present utility model, in the circular hole on the cover plate of case lid setting-in tank cap lock, ratchet has been fixed in the lower end of the locking bar of tank cap lock, in that case lid cooperates with oiling mouth of pipe spiral shell button is fastening, rotating rod lock, ratchet embed oiling mouth of pipe inwall the ring week groove.

As further improvement of the present utility model, have by nut with the fastening backboard of tank cap lock at the inner face of case lid, the conduit that backboard periphery and circular hole are linked up is mutually arranged on the inner plane of backboard.

As further improvement of the present utility model, be distributed with screw on the ring wall of box cupling and have the twisted off type anti-theft screw to run through and be fastened with reservoir port.

The beneficial effects of the utility model are, simple in structure, the convenient use can prevent effectively that oil plant is excessive and stolen, reduces the various losses that cause because of oil plant is stolen, and the design of conduit on the backboard, make fuel tank have good permeability, safe advantage.

The specific embodiment

Safe antitheft fuel lid of the present utility model, be to constitute by case lid 1, box cupling 2, screen casing 3 and screen cloth 4, box cupling 2 and the oiling mouth of pipe 5 gap intussusception mutually fuse, suitable for reading and the case lid 1 of the oiling mouth of pipe 5 spiral shell mutually links and connects cooperation, the end opening of the oiling mouth of pipe 5 has connected screen casing 3, the lower end of screen casing 3 has screen cloth 4 to seal, and described screen cloth 4 is plate shaped.The guard against theft oil case lid can be enclosed within on the reservoir port during use, make reservoir port between the box cupling 2 and the oiling mouth of pipe 5, use the twisted off type anti-theft screw fastening then.Open case lid 1, rfl, oil are by the some sieve apertures on the screen casing or flow into fuel tank through screen cloth again.

In the circular hole 6 on the cover plate of case lid 1 setting-in tank cap lock 7, ratchet 8 has been fixed in the lower end of the locking bar of tank cap lock 7, case lid 1 cooperates fastening with the oiling mouth of pipe 5 spiral shell buttons, if under no key situation, rotate case lid, locking bar rotates thereupon, can drive in all grooves of ring of the ratchet 8 embedding oiling mouths of pipe 5 inwalls, to play safety effect.

Have by nut 10 with the fastening backboard 11 of tank cap lock 7 at the inner face of case lid 1, the conduit 12 that backboard periphery and circular hole 6 are linked up is mutually arranged on the inner plane of backboard 11.Because circular hole 6 is metallic material with tank cap lock 7, has certain slit, this slit communicates with conduit 12 on backboard 11 inner planes, makes fuel lid maintenance air permeability and good.

On the ring wall of box cupling 2, be distributed with screw and have twisted off type anti-theft screw 9 to run through and be fastened with reservoir port.When screw 9 was applied certain external force, exterior hexagonal nut head can break, and remainder is circular, not quick detachable.
