Abstract

The fuel door switch of the anti-theft fuel tank consists of a main fuel pipe 1, an auxiliary fuel pipe 2, a connecting nut 3, a lock core shell 4, a lock core 5, a transparent oil cup 6 and a cone valve 14, and is mainly characterized in that a built-in lock core with a double-channel lock bead hole is arranged in the shell, the cone valve 14 with an overflow groove 16 can be driven to rotate by a lock core spring behind the lock core through the unlocking of a key so as to open and close the throttle, the throttle can be locked and the oil path can be cut off, and the vehicle cannot be stolen easily even if a power lock and a front fork lock of the motorcycle are damaged. The throttle switch is suitable for various two-wheeled and three-wheeled motorcycles.

Description

Anti-theft oil tank opening-closing device

The utility model relates to a kind of Anti-theft oil tank Oil Switch, belongs to the motorcycle accessories class, is a kind of improvement to present motorcycle oil door switch.

Motor bike has become a kind of walking-replacing tool quickly and easily in people's life.Existing motorcycle oil door switch does not have anti-theft feature, so occur in the fuel tank the stolen incident of walking of fuel oil in daily life often, is perhaps stolen by the people by the artificial vehicle that damages later on because of power supply lock and Front fork lock.

The purpose of the present utility model is to provide a kind of Anti-theft oil tank Oil Switch, wishes that it can prevent that the robber from stealing oil, can prevent that again the robber from stealing car; Even for after wrecking, also can't open Oil Switch and can not steal vehicle easily motor bike power supply lock and Front fork lock people.

This Anti-theft oil tank Oil Switch is made of major and minor oil pipe, coupling nut, housing, core, transparent lubricating cup, cone valve, spring, seal ring, locking closure etc., it is characterized in that described core places in the lock housing body that is " cross " type, the depression draw-in groove of horizontally-arranged key is being set on the last disc of this core, outside in setting gradually the stop positioning groove on its cylinder, the hole of bead, core location and corresponding double key hole and three groups of lock hole of beads of putting; Disc connects through a core spring cone valve under it, and stop screw and positioning bead are being settled in its " cross " type top of described core housing; Its left and right both wings are being provided with three groups and corresponding spring duct, the core hole of bead, and the locking closure of energy self-return is being settled in its underpart, on the described core seal ring is being set.

Described cone valve has the arc overflow groove of-3/5 arc length on its taper cylinder.

According to the Anti-theft oil tank Oil Switch of above conceptual design, its advantage is: control is convenient, and good seal performance can prevent that fuel oil is stolen in the motorcycle tank; Even be damaged under the situation, can only utilize in the gasifier oil storage 300-500 rice that travels at most at Vehicle Power lock, Front fork lock; In exhausting gasifier, behind the trapped fuel, vehicle can't be stolen because of continuing fuel feeding.

The each several part member respectively claims as follows among the figure:

1, oil main line 2, secondary oil pipe 3, the coupling nut 4, core housing 5, core 6, transparent lubricating cup 7, locking closure 8, stop screw 9, core seal ring 10, positioning bead groove 11, locking closure pull back spring 12, lubricating cup seal ring 13, slip through the net 14, cone valve 15, core spring 16, overflow groove 17, the stop positioning groove.

Further describe the utility model below in conjunction with accompanying drawing, and provide embodiment.

The utility model is a kind of improvement to present Yamaha 125 motorcycle tank Oil Switchs.Its principal feature is that a core 5 in " cross " type core housing 4 is set before the cone valve of former switch; The depression draw-in groove of horizontally-arranged key is being set on the last disc of this core, on the core cylinder, outside in set gradually the hole of bead, stop positioning groove, core location correspondence and three groups of lock hole of beads that the key hole face is put, disc connects with cone valve 14 through a core spring 15 under it, described core housing 3, its " cross " type top is being provided with stop screw 8 and positioning bead groove 10, stretch into stop positioning groove on the core for 8 times by stop screw, core 5 can not outwards be skidded off; Owing to be provided with spring and steel ball in the positioning bead groove 10, this steel ball can snap in the hole of bead, location of core cylinder when core 5 forwards certain position to simultaneously; At core housing 4 left and right sides both wings three groups of ducts relative with the core hole of bead are being set, the locking closure 7 that is subjected to 11 controls of locking closure pull back spring is being settled in its underpart, on the core 5 core seal ring 9 is being set also simultaneously.

Described cone valve 14 has the arc overflow groove 16 of-3/5 arc length on its taper cylinder.

In use, this Oil Switch is rotatably connected on the motorcycle tank oil outlet through coupling nut 3 gets final product.When parking is deposited, as long as key is screwed into the oil circuit off-position with core 5, extract key after, not only cut off oil circuit simultaneously but also locked Oil Switch, reach the purpose of not only guard against theft oil but also antitheft car.

Accompanying drawing 6～8 has provided the working state figure of the utility model cone valve 14.

When inserting key alignment OFF (Fig. 6), no matter at this moment arc overflow groove 16 arcs of this cone valve 14 top be oil main line 1 upwards, and still secondary oil pipe 2 all can't enter oil outlet by transparent lubricating cup 6.And when 90 ° of key backward rotation (Fig. 7), when aiming at the ON position, the oil of oil main line 1 then can enter transparent lubricating cup 6 through arc overflow groove 16 curved channels of cone valve 14, and flows to oil outlet after filtration and use for driving engine; Same when key clockwise 90 ° (Fig. 8), during key alignment RES, the oil of secondary oil pipe 2 then can enter transparent lubricating cup 6 through cone valve 14, and send into oil outlet and engine operation after filtration; When key forwarded the OFF position again to, the positioning bead of being located in the positioning bead groove 10 then snapped in the hole of bead, location that the core of feel cylinder can be arranged under action of the spring; At this moment extract key out, promptly reach the cut-out oil circuit, close the purpose of throttle.
