Abstract
The utility model relates to an anti-turn device for an oil discharging screw plug of an oil tank, composed of a screw plug, a lock body, a lock core, a lock bolt, etc. The lower end of the screw plug is fixedly connected with a lock pin with an annular groove, and the end of the lock pin is hemispherical. The upper end of the lock body is provided with a circular plugging hole of the lock pin. The position of the lower part of the plugging hole, which corresponds to the annular groove of the lock pin.,is provided with a concave cavity of the lock bolt, a spring and the lock bolt which can be clamped with the lock pin are arranged in the concave cavity of the lock bolt. The lock core is clamped on the end surface of a square slot in the middle of the lock bolt through a vertical angle notch edge, so as to control the lock bolt to clamp the lock pin. The utility model has the advantages of simple structure, easy manufacture, convenient and reliable use, etc., and the utility model does not use the lock body to transfer force.
Description
The utility model relates to a kind of fluid box, particularly the Device for preventing rotation of the drain plug of draining the oil of fuel tank.
Existing vehicle and other are equipped with fuel tank with ICE-powered machinery.Be to discharge ponding and dirt in the case, a drain screw be housed in the fuel tank bottom, when needs clean fuel tank, can turn the plug screw lower end be exposed to outer six-sided head screw off plug screw then can, steal oily person and steal oil convenience is provided but also give simultaneously; A kind of fluid box drain plug automatic safety lock (application number is 88218106.8) is disclosed in CN2030239U, it is by plug screw, compositions such as lock body, lock core and lock pin, when making plug screw lock locking, lock pin breaks away from plug screw, lock body can only dally around plug screw, and lock pin inserts plug screw when unblanking, and makes lock body drive plug screw and rotates.Its weak point is a complex structure, and it is difficult to make, and because of coming power transmission by lock pin, so power transmission is relatively poor during the dismounting plug screw.
The purpose of this utility model is that design a kind ofly can be avoided the simple in structure of above-mentioned deficiency, thereby lock body can separate the drain plug of fuel tank Device for preventing rotation that need not add power transmission with plug screw.
The purpose of this utility model realizes by following structure: the drain plug of fuel tank Device for preventing rotation is made of plug screw and lock body, lock core.The affixed lock pin in the plug screw lower end, the lock pin bottom is milled with annular groove, and hemisphere face is made in the end.The one lock pin circular hole that can contain plug screw lower end six-sided head and lock pin is arranged on the lock body, on lock body middle part and lock pin annular groove correspondence position, a locking bolt cavity is arranged, the wedge shape locking bolt that the locking bolt spring is arranged in the chamber and can engage with lock pin, this locking bolt middle part has the right angle incision checkpost of a square groove and lock core to close.When preventing that stealing oily person steals oil locking plug screw, the lock pin circular hole is inserted in plug screw lower end and lock pin, the wedge shape locking bolt is by the locking bolt action of the spring, automatically be stuck in the annular groove, the six-sided head of plug screw lower end is included in the columniform lock pin circular hole, thereby make and steal oily person and can only turn lock body and dally around plug screw, plug screw does not change, and then can not steal oil; When draining the oil blowdown when needs cleaning fuel tank, lock core drives the annular groove that locking bolt withdraws from lock pin, and lock body breaks away from plug screw, and the six-sided head of plug screw lower end exposes, and turns six-sided head and just can screw off plug screw, cleans fuel tank, the eliminating greasy dirt.
Description of drawings of the present utility model is as follows:
Fig. 1 is the cutaway view of drain plug of fuel tank Device for preventing rotation;
Fig. 2 is the right elevation of Fig. 1;
1 plug screw, 2 lock pins, 3 lock pins circle jack, 4 wedge shape locking bolts, 5 locking bolt springs, 6 lock cores, 7 top flats, 8 hold out against spring, 9 lock bodies, 10 packing seals, 11 dust protecting caps, 12 annular grooves, 13 locking bolt cavitys, 14 lock pin cavitys among the figure
Below in conjunction with drawings and Examples the utility model is further described:
As shown in the figure, the drain plug of fuel tank Device for preventing rotation is by plug screw (1) lock body (9) and lock core (6) and locking bolt (4) formation, can weld a lock pin (2) (perhaps lock pin (2) is made of one with plug screw) in plug screw six-sided head bottom, the lock pin bottom is milled with an annular groove (12), and semisphere is made in the lock pin lower end; There is lock pin circle jack (3) the lock body upper end, in lock pin circle jack, locking bolt cavity (13) is arranged with the cooresponding position of lock pin annular groove (12), wedge shape locking bolt (4) that can engage with lock pin earlier and locking bolt spring (5) are packed into from locking bolt cavity bottom, shut at the bottom of the chamber then, have the right angle incision checkpost of a square groove and lock core (6) to close at locking bolt middle part, lock core (6) is that to adopt the form of spring lock to insert the lock core hole of lock body interior.For waterproof and dustproof, on the six-sided head top of plug screw (1) packing seal (10) is arranged, one dust protecting cap (11) that is flexible coupling by screw with lock body is arranged outside lock core, for the shake of the lock pin after preventing to engage rapid wear, at lock body lock pin circular hole bottom system one lock pin cavity (14), put into top flat (7) at the bottom of the chamber and hold out against spring (8) and shut then at the bottom of the chamber.Spring passes through the top flat locking pin, thereby reaches the purpose that prevents lock pin shake rapid wear.
That the utility model compared with prior art has is simple in structure, make and easily, do not need by lock body power transmission, the advantage such as easy to use and reliable.
