Abstract

The utility model discloses an anti-theft cover of a fuel tank of a motor vehicle, which comprises a lock cylinder (1) and a fuel tank cover (2) connected with the lock cylinder (1). The anti-theft cover is characterized in that a cylinder (3) is movably sleeved outside the lock cylinder (1), an ejection spring (4) is arranged between the cylinder (3) and the lock cylinder (1), two opposite movable outer searching pins (5) are arranged at the lower end of the lock cylinder (1), the outer ends of the movable outer searching pins (5) are provided with gradient and exposed on the lateral outside of the lock cylinder (1), and a spring (6) is movably connected with the inner ends of the movable outer searching pins (5). The anti-theft cover is matched with an annular outer layer cover fixed at the position of a fuel tank opening for use. When the fuel tank cover is locked, the lock cylinder and the sleeve are inserted in a cavity of the annular outer layer cover, the cylinder is clamped, the lock cylinder continuously pushes downwards, the movable outer searching pins are ejected and clamped below the central bottom edge under the effect of the spring to lock the fuel tank cover with the lock cylinder when a certain position is arrived. When the fuel tank cover is opened, users can use a key to rotate the lock cylinder to retract the movable outer searching pins, and the lock cylinder moves upwards under the effect of the ejection spring to open the fuel tank cover. The anti-theft cover is simple in structure, convenient in operation, not apt to damage the lock cylinder and long in service life.

Description

The motor vehicle oil tank pilfer proof closure

Technical field

The utility model belongs to the self-propelled vehicle annex, is a kind of pilfer proof closure of motor vehicle oil tank particularly.

Background technology

In the prior art, the self-propelled vehicle especially fuel tank of truck is often stolen, and its reason is that the fuel lid anti-theft feature is poor.On November 10th, 2010, State Intellectual Property Office discloses the applicant's a patent, and name is called " motor vehicle oil tank anti-joyride device ", and publication number is CN201626303U.This patented technology includes: fuel lid and the lock core that connects with it; Outside lock core, be movably installed with the sleeve on band card edge, upper end; Sleeve is movably installed with the ring-shaped outer layer lid outward, and movable screw is connected to the annular snap board in the sleeve lower end, and the outer of annular snap board is provided with several protruding dops; 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 pilfer proof closure is provided, and it is simple in structure, and locking is convenient with unlatching, and durable not fragile, theftproof performance is strong.

For reaching above-mentioned purpose; The utility model is taked following technical scheme: the utility model includes: lock core and the fuel lid that connects with it thereof; It is characterized in that: lock core is movably installed with sleeve outward, between sleeve and lock core, is equiped with the top spring, and the lock core lower end is equiped with two relative movable outer pins of visiting; The movable outer outer end of visiting pin has the gradient and is exposed to the cylinder side outside, and the movable dress in inner end is associated with spring.

The utility model is taked technique scheme, has following beneficial effect: the utility model and ring-shaped outer layer of the prior art cover supporting use, and the ring-shaped outer layer lid is fixed in 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.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.

Fig. 1 is the structure diagram of the utility model embodiment.

Mark among the figure: pin, 6-spring, 7-dop are visited in 1-lock core, 2-fuel lid, 3-sleeve, 4-top spring, 5-activity outward.

The specific embodiment

By shown in Figure 1: the utility model includes: lock core 1 and the fuel lid 2 that connects with it thereof; The lock core 1 outer sleeve 3 that is movably installed with; Between sleeve 3 and lock core 1, be equiped with top spring 4; Lock core 1 lower end is equiped with two relative movable outer spies and sells 5, and the movable outer outer end of visiting pin 5 has the gradient and is exposed to lock core 1 side outside, and the movable dress in inner end is associated with spring 6.

Described activity is visited pin 5 outward and is provided with the dop 7 with sleeve 3, and when being convenient to lock core 1 and moving down, the movable outer pin 5 of visiting can lean out.

Claims

1. motor vehicle oil tank pilfer proof closure; It includes: lock core (1) and the fuel lid (2) that connects with it thereof; It is characterized in that: lock core (1) is outer to be movably installed with sleeve (3), between sleeve (3) and lock core (1), is equiped with top spring (4), and lock core (1) lower end is equiped with two relative movable outer pins (5) of visiting; The movable outer outer end of visiting pin (5) has the gradient and is exposed to lock core (1) side outside, and the movable dress in inner end is associated with spring (6).
