Abstract

The utility model discloses a motor vehicle fuel tank antitheft apparatus, comprising an annular outer-layer cover (1), an annular locking board (2) and a fuel tank cover (4) with a lock cylinder (3). The motor vehicle fuel tank antitheft apparatus is characterized in that the annular locking board (2) is connected with the annular outer-layer cover (1) through bolts (6); a jacking spring (7) is disposed between a sleeve (5) and the lock cylinder (3); the lower end of the lock cylinder (3) is provided with two opposite movable externally-extending pins (8); a spring (9) is movably disposed between inner ends of the opposite movable externally-extending pins (8); and the opposite movable externally-extending pins (8) are opposite to the central bottom edge of the annular outer-layer cover (1). During locking of the fuel tank cover, the lock cylinder and the sleeve are inserted in an inner cavity of the annular outer-layer cover; when the lock cylinder and the sleeve are inserted to a certain position, the sleeve gets stuck and the lock cylinder is pushed downward continuously; and the movable externally-extending pins extend out by the action of the spring and are stuck below the central bottom edge for locking the fuel tank cover provided with the lock cylinder. During unlocking of the fuel tank cover, the lock cylinder is rotated via a key for making the movable externally-extending pins retract, and the lock cylinder shifts upward by the action of the jacking spring for opening the fuel tank cover. The motor vehicle fuel tank antitheft apparatus is simple in structure and easy to operate, prevents the lock cylinder from being damaged easily and has a long service lifetime.

The motor vehicle oil tank anti-joyride device

Technical field

The utility model belongs to the self-propelled vehicle annex, is a kind of anti-joyride device of motor vehicle oil tank particularly.

Background technology

In the prior art, the fuel lid materials of self-propelled vehicle are thin insecure, are easy to destroyed by the lawless person, steal fuel oil wherein.In order fuel lid to be played further protection, avoid fuel tank to be destroyed stolen, some oil box theft-proof caps have appearred in the market, and State Intellectual Property Office also discloses some relevant patent documentations.On November 10th, 2010; It is that CN201626303U, name are called the patent of " motor vehicle oil tank anti-joyride device " that State Intellectual Property Office discloses a kind of publication number; This patented technology includes: fuel lid and the lock core that connects with it, and outside lock core, be movably installed with the upper end band and block the sleeve on edge, sleeve is movably installed with the ring-shaped outer layer lid outward; Movable screw is connected to the annular snap board in the sleeve lower end; The outer of annular snap board is provided with several protruding dops, and ring-shaped outer layer covers be fixedly connected long spacer and short spacer, and the annular snap board is provided with perforating movable and is sleeved on outside the long spacer.Be equiped with in the lock core lower end and visit pin outside the plurality of movable, the movable outer outer end of visiting pin is exposed to the cylinder side outside, and the movable dress in inner end is associated with flexure strip.The deficiency of its existence is: complex structure, and make trouble is installed; The movable outer pin of visiting in the lock core leans on flexure strip control, and occur the flexure strip off normal easily and control insensitive phenomenon, and perishable, service life is short; When lock core blocks reservoir port, need just can lock lock core, inconvenient operation with the key rotation then with on the Lock cylinder cover.

Summary of the invention

The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of improved motor vehicle oil tank anti-joyride device is provided, and it cooperates connection with reservoir port, both had stronger theftproof performance, has advantages such as easy to use, not perishable, that the life-span is long again.

For reaching above-mentioned purpose; The utility model is taked following technical scheme: the utility model includes: the fuel lid of ring-shaped outer layer lid, annular snap board and core with lock; Outside lock core, be movably installed with sleeve; The outer movable set ring-shaped outer layer lid of sleeve is characterized in that: the annular snap board connects with the ring-shaped outer layer lid through bolt; Between sleeve and lock core, be equiped with the top spring; The lock core lower end is equiped with two relative movable outer pins of visiting; The outer end that spy is sold outside movable has the gradient and is exposed to the cylinder side outside, and the movable dress in inner end is associated with spring, and the spy pin is relative with the center bottom edge that ring-shaped outer layer covers outside the activity.

The utility model is taked technique scheme, has following beneficial effect: when the utility model uses, at first through the annular snap board ring-shaped outer layer lid is installed on the reservoir port place.During the lock fuel lid; Related its exterior sleeve of lock core is inserted in the inner chamber of ring-shaped outer layer lid, and when arriving certain position, sleeve is stuck motionless; Under continuing, the related fuel lid of lock core pushes away; Overcome the top spring force lock core movable outer visited the below that pin is shifted the center bottom edge of ring-shaped outer layer lid onto, movable outer visit pin eject under the effect of spring be stuck in the center bottom edge below, with the fuel lid locking of core with lock.When opening, use the key rotary locking cylinder, make the movable outer pin withdrawal of visiting, moving on the lock core under the effect of top spring, open fuel lid.The utility model is simple in structure, and is easy to operate, and lock core is not fragile, long service life.
