Description

Modified heads straight for padlock
Technical field
The utility model relates to a kind of daily life tools, a kind of more precisely locking device that heads straight for padlock.
Background technology
At present, the padlock that heads straight on the market all exists the unlatching back to leak key more than 90%, locking pressure sensitivity feel at present is low and deep defective obviously, at these problems, people attempt to adopt the multiple technologies means to solve, but effect is not satisfactory, as for lock bridge is pressed down easily, the dead bolt face is cut out an inclined-plane, the result has but reduced the security performance after the locking, dead bolt is easily gone into to open by the special tool(s) skewer, Chinese patent 92203263.7 disclosed " a kind of padlock " and for example, it is the further improvement to original padlock, principal character is that the lock ring groove on the lock ring both sides is square, the dead bolt front end is the semicircle tangent plane, when padlock is locked, two 45 degree inclined-planes of lock ring both sides press down, impel the withdrawal of dead bolt front end semicircle tangent plane, after the lock ring playback, dead bolt front end semicircle tangent plane just inserts respectively in the lock tongue slot that the lock ring both sides are square, though this padlock can effectively prevent tagger, the slit of apparatus such as razors slice between lock ring inboard and lock body inserted lock opened, and opens back leakage key but still can not solve padlock, press down low and deep problem during locking.
The utility model content
At the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of rational in infrastructure, conveniently opening and closing, modified that locking is more firm to head straight for padlock.This padlock can not turn round at the unlatching rear lock core, and dead bolt and lock bridge rubbing surface are little during locking, leaks key and presses down low and deep problem thereby solved padlock well.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of modified heads straight for padlock, comprise lock body, lock bridge, lock core, dead bolt, latch bolt spring and lock core marble, offer lock tongue slot on the lock bridge, it is half-cylindrical that the dead bolt main body is, its front end is a cylindrical solid, the front end of this cylindrical solid cuts out a half-cylindrical locking head that is used to snap in lock tongue slot, offers on the dead bolt main body and the corresponding breach of the lock core foot of lock core, and the middle part of its side plane offers spring groove.
Described half-cylindrical dead bolt main body and half-cylindrical locking head are crisscross arranged at the two ends of cylindrical solid, and promptly the side plane of dead bolt main body is spatially vertical mutually with the side plane of locking head.
Breach on the described dead bolt main body is near its end, and the lock core foot of width and lock core is suitable.
Gap width on the described dead bolt main body equals the width sum of dead bolt stroke and lock core foot.
Described lock bridge cuts certain radian with the end that lock body is connected by spring and forms concave plane on medial surface, should in the spacing of the upper edge of concave plane and lock tongue slot lower edge more than or equal to lock bridge from opening the up and down stroke of shoulder state to locking states, after padlock was opened shoulder, the locking head of dead bolt was withstanding on the face of cylinder of lock bridge under the effect of spring.
Described spring groove semicircular in shape on the cross section.
Described spring groove stretches into the cylindrical solid certain distance, forms a coil component spring jack at the middle part of cylindrical solid.
The utility model removes the inclined-plane that existing dead bolt cuts out, change a cylindrical solid into, front end in cylindrical solid cuts out half-cylindrical locking head again, improved the firmness of dead bolt, the utility model has also been done further improvement to the size of dead bolt breach and the spacing of lock bridge inner concave and lock tongue slot, padlock will directly withstand on the face of cylinder of lock bridge at the half-cylindrical locking head of opening its dead bolt of shoulder back like this, and then key just can't returned, avoided leaking the generation of key phenomenon, and because contact for line between locking head and the lock bridge face of cylinder, frictional force is little when relatively sliding, so the low and deep sense when lock bridge presses down obviously alleviates, feels very light.

Fig. 3 heads straight for the dead bolt structural representation of padlock for the utility model modified, and wherein Fig. 3 (b) is the left view of Fig. 3 (a), and Fig. 3 (c) is the right view of Fig. 3 (a), and Fig. 3 (d) is the vertical view of Fig. 3 (a).
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of reference numerals is as follows
1---lock body 2---lock bridge
3---lock core 4---dead bolt
5---latch bolt spring 6---lock tongue slot
7---cylindrical solid 8---locking head
9---lock core foot 10---lock core foot breach
11---lock bridge spring 12---spring groove
The interior concave plane of 13---spring jacks 14---
15---key
Modified as shown in Figure 1 and Figure 2 heads straight for padlock, and its main component comprise lock body 1, lock bridge 2, lock core 3, dead bolt 4, latch bolt spring 5 and lock core marble (not shown), offer lock tongue slot 6 on the lock bridge 1.
As shown in Figure 3, it is half-cylindrical that the main body of dead bolt 4 is, its front end is a cylindrical solid 7, the front end of cylindrical solid 7 cuts out a half-cylindrical locking head 8 that is used to snap in lock tongue slot, half-cylindrical dead bolt main body and half-cylindrical locking head 8 are crisscross arranged at the two ends of cylindrical solid 7, the side plane of dead bolt main body is spatially vertical mutually with the side plane of locking head 8, offer lock core foot 9 corresponding breach 10 on the dead bolt main body with lock core, this breach is near the end of dead bolt main body, the lock core foot 9 of its width and lock core is suitable, equal the width sum of dead bolt stroke and lock core foot 9, do not resemble random offering the existing dead bolt, even for conservation the undue increasing of breach, the middle part on dead bolt main body side plane offers semicircle spring groove 12, spring groove 12 stretches into cylindrical solid 7 certain distances, middle part in cylindrical solid 7 forms a coil component spring jack 13, lock bridge 2 cuts certain radian with the end that lock body 1 is connected by spring and forms concave plane 14 on medial surface, the spacing of the upper edge of concave plane 14 and lock tongue slot 6 lower edges is more than or equal to the up and down stroke of lock bridge 2 from opening to locking states in being somebody's turn to do, like this after padlock is opened shoulder, the locking head 8 of dead bolt 4 will withstand on the face of cylinder of lock bridge 2 under the effect of spring, rather than heads in the interior concave plane 14.
As Fig. 1, shown in Figure 2, when key 15 drives lock core foot 9 rotations of lock core 3, lock core foot 9 will drive dead bolt 4, its locking head 8 is withdrawn from the lock tongue slot of lock bridge, lock bridge is backed down under the effect of spring 11, this moment, the locking head 8 of dead bolt withstood on the face of cylinder of lock bridge and direct braking lock core, make lock core can't be returned to the normal position, like this with regard to because lock core marble hole and lock core can't align and make key can not drop out lock core, because locking head 8 contacts for linear with lock bridge 2, frictional force is little between the two, seems very light when therefore pressing down simultaneously, during locking, lock bridge 2 presses down, and dead bolt 4 stretches into dead bolt groove 6 automatically under the effect of spring, realizes locking, breach on the dead bolt 4 drives lock core foot 9 makes lock core get back to the position that lock core marble hole and lock marble hole align, and key 15 can be extracted from lock core like a cork.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but on its shape or structure, do any variation; every have identical with a application or akin technical scheme, all drops within the protection domain of the present utility model.
