Abstract

The utility model relates to spring hanging lock, which is especially suitable for safety protection. In the utility model, the distance between the center line of a lock beam and the center line of a lock core is L; the lock core is used as the set bar, and the set bar is engaged with the long arm and the short arm of the lock beam simultaneously. The utility model has simple structure and easy fabrication; moreover, the consumption of the copper material can be saved; with the double set bar constitutive relation, the key can not be dismounted after the door is opened.

Description

Twin bolt biasing cylinder and pin lock

The utility model is a kind of padlock that is specially adapted to safety precaution.

Present widely used spring padlock can be divided into two types of straight-opening type and inclined to one side open types substantially.General straight-opening type structure also is provided with the groove that has the engagement dead bolt on dead bolt structure, the lock bridge specially except that members such as lock body, lock core, lock bridge, lock bridge back-moving spring, lock bridge spacer pin, dead bolt is bumped in the groove when sealed.Therefore this lock tensile strength is higher.But its shortcoming is that under opening, key can arbitrarily be extracted, and tapered end and key are separated, and often occurs easily key not being taken out of and having been locked door, causes a series of troubles.Inclined to one side open type tapered end, general structure is identical with straight-opening type, usually their lock bridge center line and lock core center line coincide, lock core and lock body are movingly, reset eccentric spring, lock core dowel of lock bridge, lock bridge back-moving spring, lock bridge spacer pin and lock core respectively is installed on the control corresponding position, realizes sealed or opens by lock core tail end control lock beam long arm end.After its was opened, lock core was subjected to the restriction of lock bridge long arm end cylinder, stoped lock core to reset, thereby key can not extract, and can prevent from key forgotten in indoor phenomenon to take place.When sealed, lock core is by eccentric spring reset.But it is not owing to there is the dead bolt structure, so the tensile strength of lock bridge is lower, safety is relatively poor, is turned on easily.

The purpose of this utility model is to avoid weak point of the prior art, and provide a kind of with lock core as dead bolt, tensile strength height, and open the twin bolt biasing cylinder lock product that back key and tapered end are not separated again.

Can reach the purpose of this utility model by following measure.Make lock bridge center line and lock core center line at a distance of L, mesh control as dead bolt simultaneously from the long and short arm end of lock bridge, on the cylinder of lock core two ends, open the plane A, the B that allow lock bridge to move up and down with lock core; Length arm cylinder at lock bridge has the short slot that coincide with the lock core cylinder; Other parts structure and existing inclined to one side open type basically identical.

Below in conjunction with accompanying drawing embodiment content of the present utility model is done further to comment.

Fig. 1. twin bolt biasing cylinder lock overall appearance figure,

Fig. 2. lock bridge galianconism end structure concerns schematic diagram (E-E section) during unlatching,

Fig. 3. lock bridge long arm end structural relation schematic diagram (F-F section) during unlatching,

Fig. 4. lock bridge galianconism end structure concerns schematic diagram (E-E section) when sealed,

Fig. 5. lock bridge long arm end structural relation schematic diagram (F-F section) when sealed.

Among the figure: (1) lock body; (2) lock cylinder; (3) lock bridge; (4) lock bridge back-moving spring; (5) lock bridge alignment pin; (6) lock core key guide groove.

The lock bridge center and the lock core center line of twin bolt biasing cylinder lock are separated, and both are at a distance of L, and lock bridge in the present embodiment (3) at a distance of L, makes lock bridge cylindrical and lock core cylindrical maintenance overlapping relation on the right side of lock core (2), so just can realize that lock core has the dead bolt function concurrently.

On the cylinder of the relative lock bridge in lock core (2) two ends, become 40 ° of angles to have plane A, the B that allows lock bridge to move up and down with lock core key guide groove (6), and A, B is on the same side.A, B face also can be left by other angle, position relation.A face and lock bridge galianconism end are had an effect in this example; B face and lock bridge long arm end are had an effect.When A, B plane were to guarantee to open, the long and short arm of lock bridge all was not obstructed, and allowed lock bridge to rise smoothly under the effect of its back-moving spring (4), the disengage from relation.

The long and short arm cylinder of lock bridge (3) has circular arc short slot C, the D that can match with the lock core cylinder, and two grooves are on the sustained height.The C short slot of galianconism end, the D short slot of long arm end is when sealed, face of cylinder engagement with lock core (2), lock bridge is obstructed along the mobile of direction of center line, the part that this moment, lock core face of cylinder lock bridge C, D arc groove matched promptly is equivalent to two place's dead bolt structures, long and short arm to lock bridge locks simultaneously respectively, does not allow it to deviate from.

The structure of the other parts of twin bolt biasing cylinder lock is with existing to drive cylinder lock partially consistent, and it also has key can not extract structural relation and the lock core eccentric spring that resets, and resets when impelling lock core sealed.

When lock is opened, key inserts the lock core key guide groove, turn clockwise after 40 °, the motion of alignment pin restriction lock core, A on the lock core, B face are by the locked state at 40 ° of angles, the long and short arm cylinder that changes A, B face and lock bridge into is tangent, and lock bridge rises to the Lift of lock bridge alignment pin (5) control under the effect of spring (4).And the B face is subjected to the restriction of the long-armed tail end of lock bridge, rests on the position at 40 ° of angles, and then key can not be extracted.Unlatching is finished.

When sealed, lock bridge presses down, when the long-armed tail end of lock bridge descend with the B emaciated face from the time, C on the long and short arm of lock bridge, D circular arc short slot put in place simultaneously, and lock core rotates 40 ° of angles to counter clockwise direction under the effect of eccentric spring, dead bolt on the lock core is locked in C, the D groove, lock core (key guide groove) returns to vertical state, i.e. alignment pin institute extreme position, and key can be extracted.Sealed finishing.

The relative prior art of the utility model has the following advantages:

1. needn't set up the dead bolt member, the lock core dual-use material, simple structure, copper material consumption is saved in easily processing and manufacturing;

2. have the double lock tongue structural relation, improve tensile strength. Can reach 1960N/f through the quiet pulling force of test for tensile strength, surpass the former 1274N/f that partially unblanks. Again since the dead bolt geometry in obtuse angle, it bears quiet pulling force ability and also is better than the existing acute angle dead bolt that heads straight for lock;

3. after opening, key still can not unload, and avoids key to separate with tapered end, causes the trouble of forgeing, and is easy to use.
