The specific embodiment
Fig. 1 has showed a kind of block diagram of safety cover type locker of guarding against theft for cars.It is mainly by lock core body 1, guard shield 2, and U-shape lock beam 3 and top handle 4 are formed.As shown in Figure 1, lock core body 1, guard shield 2 and top handle 4 are that the method by rivet or welding links into an integrated entity, and U-shape lock beam 3 is independently at the end when sealed.When sealed, as shown in Figure 2, U-shape lock beam 3 inserts from lockhole 5, passes and pass lock core body 1 and guard shield 2.
Fig. 3 is a kind of organigram of lock core body 1.Lock core body 1 mainly is made of lock core 6 and lockout mechanism 7.In this embodiment, lock core body 1 is so to make: lock core 6 and lockout mechanism 7 are assemblied in the hole of metal casting 9 by annex.Have on the lock core body 1 and penetrate lockhole 5.In this embodiment, lock bridge is a U-shape lock fine strain of millet, and U-shape lock fine strain of millet has 2 interspersed posts 10 and locked groove 8.When U-shape lock beam 3 penetrates lockhole 5, the locked groove 8 on the U-shape lock beam 3 is blocked by lockout mechanism 7, and U-shape lock beam 3 can not be moved up and down.
Fig. 4 and Fig. 5 are the block diagram and the detail drawings of guard shield 2.In this embodiment, guard shield 2 is made by steel plate.Guard shield perforation 11 can allow U-shape lock beam 3 pass.Guard shield 2 has U type front end 12, and U type front end 12 is to be formed by the bending of steel plate front end.Fig. 6 has showed that safety cover type locker of guarding against theft for cars is placed on the condition of service on the bearing circle 13.Guard shield 2 twists 14 back to the connection of bearing circle 13, and U type front end 12 hangs on the outer toroid 15 of bearing circle 13.U type front end 12 can outer toroid 15 by three bread covers.When U-shape lock beam 3 is inserted from lockhole 5, the post 10 that interts passes and passes lock core body 1 and guard shield 2.The interspersed post 10 and U type front end 12 completely encircles that pass outer toroid 15.Fig. 7 is the section-drawing that is locked in bearing circle 13 on the safety cover type locker of guarding against theft for cars.As shown in Figure 7, the interspersed post 10 that passes is very approaching with the distance D of U type front end 12, and D is far fewer than 2 centimetres, and the minimum diameter of outer toroid 15 is 2.5 centimetres, so outer toroid 15 is impossible walk out from this clearance aperture.
Fig. 8 has removed lock core body 1, and the guard shield rear portion is cutd open, the scheme drawing of U-shape lock beam and U type front end keyed bearing circle.From Fig. 7 and Fig. 8 as can be known, the U type front end 12 of guard shield 2 with outer toroid 15 3 bread of this part round, make safety cover type locker of guarding against theft for cars can not before, back and moving down.After locking U-shape lock fine strain of millet 3, the interspersed post 10 that stretches through out can not move up safety cover type locker of guarding against theft for cars.And, since the interspersed post 10 of U-shape lock beam 3 across bearing circle 13 connection the right and left of 14 in vain, thereby make the safety cover type locker of guarding against theft for cars can not a left side, it is moving to turn right.Thereby safety cover type locker of guarding against theft for cars is locked on the bearing circle firmly.Because top handle 4 withstands on the instrument carrier panel of automobile, therefore bearing circle 13 can't be rotated and reach theft-proof purpose.
If will safety cover type locker of guarding against theft for cars be lost efficacy, have only two kinds of sawings.As Fig. 9 and shown in Figure 10, the one, near the outer toroid 15 the joint pin 14 of placing safety cover type locker of guarding against theft for cars cuts two breach (Fig. 9), then safety cover type locker of guarding against theft for cars is taken out from two indentation, there; The 2nd, joint pin 12 is sawed-off, and with the outer toroid 13 sawed-off (Figure 10) on joint pin both sides, then with sawed-off part bearing circle be locked in top safety cover type locker of guarding against theft for cars and take off in the lump.But these two methods are all right obstructed to safety cover type locker of guarding against theft for cars.As shown in figure 11, because guard shield 2 is lived the joint pin 14 of bearing circle and near outer toroid 15 ladle covers or topped live.Be impossible cut the joint pin 14 of placing safety cover type locker of guarding against theft for cars and near outer toroid 15 or sawed-off.Thereby be can't safety cover type locker of guarding against theft for cars be lost efficacy.
Still have other method that safety cover type locker of guarding against theft for cars was lost efficacy.As sawed-off top handle 4, with master key technical unlocking lock core 6, insert key hole with hard thing and reverse lock core 6 with brute force then, reverse lock core 6 or bore bad lockout mechanism 7 positions with brute force behind the hoodle of storage battery electric drill destruction lock core 6 or the key.
In this embodiment, top handle 4 is steel bars that curve the U type, and the opening of U section steel bar is welded on guard shield 2 or the lock core body 1.Top handle 4 is to be made through the hot-cured steel bar by medium-carbon steel, thereby anti-saw is prevented cutting.Lock core 6 adopts the selenodont lock core of up-to-date key hole biasing.The key hole of selenodont lock core is setovered, and can take precautions against master key effectively and anti-brute force is reversed lock core 6.
Because the restriction of lockmaking technology, the material of lock core 6 adopts copper mostly.The material of lock core body 1 generally is an E-metal.These materials are all softer.The robber bores along the position of hoodle (key) down with electric hand drill, and the hoodle (key) that just can block lock core destroys, then rotational lock core 6 and lock is opened.In addition, most of lock cores 1 are to be fixed in the lock core body 1 by the metal locating dowel pin less than 2 millimeters of diameters.Just can destroy locating dowel pin and take out lock core 6 if pierce along locating dowel pin.For lock core 6 and lock core body 1 anti-drilling anti-violence are opened, at lock core body 1 added metal box 16.In Figure 12 and the embodiment shown in Figure 13, can 16 is to be stamped to form by steel plate, is connected on the guard shield 2 with the method for welding.Can 16 complete ladle covers lock core body 1, and aperture seam 17 is only arranged, and allow key insert lock core 6 and rotation.Covering the lock core body of can, can be anti-drilling, pick-proof is prevented violence.
Lock core body 1 has many manufacture methods.For example, as shown in figure 14, lock core body 1 can directly be assemblied in the can 16 by annex by lock core 6 and lockout mechanism 7.Figure 15 extremely lock core body 1 shown in Figure 17 has only monolateral lockout mechanism 7.Though lock core body 1 shown in Figure 15 has only monolateral lockout mechanism 7 but twin-lock hole 5 is arranged.Lock core body 1 shown in Figure 16 has only monolateral lockout mechanism 7 and monolock hole 5, and this embodiment can reduce the volume and weight of lock core body 1.As shown in figure 17, the lock core body 1 of small size can be placed vertically by traverse, mid-or flatly is arranged in more neatly on the guard shield 2 with putting.
Lock fine strain of millet also can be adopted other shape.As Figure 25 and shown in Figure 26.π type lock fine strain of millet shown in Figure 25.Lock fine strain of millet shown in Figure 26 has 3 interspersed posts, and the 3rd interspersed post can be used for fixedly flexible stick formula top handle or collapsible top handle or other purposes.
