Abstract

The utility model relates to an oil drain plug with a lock, which is used in oil tanks of automobiles and motor vehicles. The utility model comprises an oil drain plug, wherein the top of a stud head of the oil drain plug is provided with a lock column with a stop groove and the lock column and the stud head are sheathed with a rotatable lock body. A lock tongue which is matched with the stop groove of the lock column is arranged in the inner side of a lock hole of the lock body, wherein one side of the lock tongue is provided with a lock core of which the tail end is fixedly connected with a shifting fork and one end of the shifting fork is matched and connected with the lock tongue. The utility model is characterized in that the lock body or the oil drain plug is provided with a magnet. The utility model has the advantages that the oil drain plug of an oil tank of a vehicle can be effectively prevented from being arbitrarily dismounted so that the safety performance of the oil storage of the oil tank of the vehicle is improved, the structure is simple, the operation is convenient, the lock body and the oil drain plug can be better attached and tightly connected through the magnet, therefore when a vehicle runs, the vibration of the lock body and the impact on the oil drain plug and the oil tank can be avoided and the oil drain plug can be prevented from looseness and damage.

Description

Oil drain plug with lock

Technical field

The utility model relates to a kind of oil drain plug with lock that is used for automobile and power actuated vehicle fuel tank.

Background technology

Fuel tank bottom at automobile and power actuated vehicle all is equipped with an oil drain plug usually, is used to get rid of sediment and removes fuel tank.Existing oil drain plug is similar to a hex bolt, uses spanner just can easily it be screwed out, and when vehicle went out to park, normal easily the generation unscrewed the fuel tank oil drain plug, and fuel oil spills or stolen situation.A kind of oil drain plug with lock is disclosed in Chinese patent ZL91201455.5, the lock body that the lock that links with the oil drain plug stud head is arranged and be enclosed within on the lock constitutes, it can prevent effectively that the oil tank of vehicle oil drain plug from being dismantled arbitrarily, has improved the safety performance of oil tank of vehicle store oil.But owing to have certain clearance between this lock body and lock, the stud head, when vehicle operating, can cause the vibration of lock body and dash (the striking) of oil drain plug and fuel tank hit that this not only increases noise, and easily makes oil drain plug loosening and impaired.

Summary of the invention

Technical problem to be solved in the utility model be the deficiency that exists at above-mentioned prior art and propose a kind of can effectively avoid oil drain plug by dismounting arbitrarily to improve oil tank of vehicle store oil safety performance, can make lock body and oil drain plug fit tightly oil drain plug with lock again to avoid vibrating and impacting.

The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: include oil drain plug, top at oil drain plug stud head 2 is provided with the lock 3 with backstop groove 4, the rotating lock body 8 of suit on lock and stud head, be provided with dead bolt 5 with lock backstop groove 4 phase configuration in the lockhole inboard of lock body, be equipped with lock core 7 in dead bolt one side, the lock core tail end is fixedly connected with shift fork 6, and shift fork one end and dead bolt are matched, and its difference is at applying magnet 10 on the lock body or on the oil drain plug.

The utility model is lock and lock body to be set on the basis of original oil drain plug and to set up magnet, and when unlocked, outside stud head was exposed to, oil drain plug can be by turn and dismounting easily; If lock body is inserted in, dead bolt springs into lock backstop groove, promptly on the oil drain plug lock, this moment is because the backstop action of dead bolt can not be deviate from lock body from lock, and can only dally around oil drain plug, because lock body covers the oil drain plug stud head, therefore can't use spanner that oil drain plug is unscrewed, thereby can prevent that oil drain plug from being opened the fuel oil that makes in fuel tank situation stolen or that bled off arbitrarily by the people and taking place, because it is the effect of magnet is fitted lock body and oil drain plug zero-clearance, closely linked simultaneously.If dead bolt is packed up, lock body is promptly removable, and this is an opening of the present utility model.

The beneficial effects of the utility model are:

1, can prevent effectively that the oil tank of vehicle oil drain plug from being dismantled arbitrarily, improve the safety performance of oil tank of vehicle store oil.

2, simple in structure, easy to use.

3, by magnet lock body and oil drain plug are better fitted, closely linked, the vibration of lock body and to the impact of oil drain plug and fuel tank in the time of can avoiding vehicle operating prevents the loosening and impaired of oil drain plug.

Description of drawings

Fig. 1 is the sectional structure chart of an embodiment of the utility model.

The specific embodiment

Further specify embodiment of the present utility model below in conjunction with accompanying drawing, include oil drain plug, oil drain plug is made of screw rod 1 and stud head 2, stud head is the hexagonal head, be provided with columniform lock 3 at the top of stud head, the backstop groove 4 that goes in ring is set on the lock, the lock head is round table-like; On lock 3 and stud head 2, be set with lock body 8, have lockhole 9 and the circular hole 11 that covers stud head in the lock body with the lock phase configuration, the lockhole inboard is provided with the elastic lock tongue 5 with backstop groove phase configuration, be equipped with lock core 7 in dead bolt one side, the lock core tail end is fixedly connected with shift fork 6, shift fork one end and dead bolt are matched, control the advance and retreat of dead bolt by the swing of shift fork, realize the opening and closing of lock.For avoid lock body when the vehicle ' idle running and rock, can in lock body, magnet 10 be set with contact position, oil drain plug stud head top, their zero-clearances are fitted.The lock body of present embodiment is inserted in and promptly automatically locks after lock puts in place, and this moment, lock body all covered stud head, and lock body can only relatively rotate on lock and can not withdraw from.
