Abstract
The utility model relates to a padlock which comprises a lock body and a lock beam, wherein the lock beam forms an inverted U shape with different lengths on both ends, and the long end of the lock beam is provided with an inclined plane, and extends into the lock body; a pin shaft is arranged in the lock body, at least one end of the pin shaft is provided with an inclined plane matched with the long end of the lock beam, and the pin shaft is axially displaced to push the inclined plane on the end of the lock beam so that the lock beam is in an unlocking or locking state; at least one surface of the pin shaft is a plane on which a plurality of notches are arranged; the pin shaft also comprises a plurality of pins, a groove is arranged on each pin, the pins is perpendicular to the pin shaft, and the grooves are matched with the plane of the pin shaft; both ends of each of the pins extend out of the lock body. The utility model can be unlocked by ciphers without a key.
Description
Technical field
The utility model belongs to field of lockset, particularly relates to a kind of padlock.
Background technology
Padlock is made up of lock body and lock bridge usually, and the lock bridge end is stretched in the lock body, forms a totally enclosed structure during locking, thereby hangs on door or other objects, therefore is called padlock.The lock bridge of the padlock that has be two ends flush inverted U-shaped, lock bridge is deviate from from lock body fully when unblanking; Different inverted U-shaped of the lock bridge two ends length of the padlock that has, short end is deviate from from lock body when unblanking, and long end is still stayed in the lock body, can axially rotate, and the utility model relates to the padlock that lock bridge can not be deviate from fully.
Existing padlock all is the open and close that comes control lock with key by lock core, inserts after the key, and rotational lock core, by certain connected mode control lock bridge, in case the key loss, padlock just can't use then.
Summary of the invention
To be solved in the utility model is that padlock must rely on the problem that key opens and closes, and a kind of padlock without key is provided.
For this reason, the utility model has adopted following technical scheme: padlock, comprise lock body and lock bridge, lock bridge is different inverted U-shaped of two ends length, and its long end has the inclined-plane, stretches in the lock body, have bearing pin in the lock body, at least one end of bearing pin is provided with the inclined-plane that matches with the long end of lock bridge, and the axial displacement of bearing pin promotes the inclined-plane of lock bridge end, lock bridge is in unblanks or blocking; At least one face of bearing pin is the plane, has several breach on the plane; It also comprises several pins, is with a groove on each pin, and pin is vertical with bearing pin to be provided with, and its groove matches with the plane of bearing pin; Stretch out outside the lock body at the pin two ends.
As technical scheme further, have a bearing pin in the lock body of the present utility model, bearing pin has two planes that parallel, and each plane all has several breach; Also be provided with a push rod in the lock body, be installed in the short end of lock bridge below, push rod has the inclined-plane, and push rod has pushing top spring; The bearing pin two ends all are provided with the inclined-plane, and an end matches with the long end of lock bridge, and the other end matches with push rod; Pin is provided with the spring cave at the back side of groove, and the inside is equipped with spring pin and bearing pin are compressed; Pin stretches out outside the lock body, indicates symbol in the relevant position of lock body, with corresponding one by one each pin of representing of pin.
The utility model does not have key, and the motion of lock bridge realizes by bearing pin, and when bearing pin can horizontal anomalous movement, lock bridge can pull-up or depressed, and utilizes the inclined-plane that bearing pin is pushed open, and its motion is freely; When bearing pin is fixed, in the time of can not horizontal anomalous movement, lock bridge just can't move, and this moment, padlock also can't be opened.And bearing pin is controlled with pin, and the trench length of pin is slightly larger than the plane width of bearing pin, and when the groove position of all pins was consistent with the bearing pin plane, bearing pin can horizontal anomalous movement, and when pin snapped in the breach of bearing pin, then bearing pin was stiff.In other words, the determining positions of pin the unlatching or the locking of padlock.Under blocking, the pin position is mixed and disorderly, always has in several breach that snap in bearing pin, and lock bridge can not be opened; Only know the position of breach on the bearing pin, could stir pin exactly, make the bearing pin can be movable, and then unblank.That is to say that the corresponding one group of password of bearing pin is known this group password, just can open padlock.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 and Fig. 3 are the schematic diagrames of bearing pin in the present embodiment.
Fig. 4 is the structural representation of pin in the present embodiment.
The specific embodiment
The following stated is an embodiment of the present utility model, and protection domain of the present utility model is not limited to present embodiment.
Referring to accompanying drawing.Padlock comprises lock bridge 1 and lock body 2, and the lock bridge two ends are different in size, and its long end has inclined-plane 11, stretches in the lock body, and lock body is provided with alignment pin 4, can block lock bridge 1, and it can not be separated with lock body 2.The short end of lock bridge has a push rod 5 12 times, and push rod has pushing top spring 6, can be with push rod 5 jack-up.Do not have lock core, lockhole in the lock body, be not with key yet.Be provided with a bearing pin 3 in the lock body, an end of bearing pin 3 has inclined-plane 7, matches with the inclined-plane 11 of lock bridge; The upper and lower surfaces of bearing pin 3 are the plane, respectively have four breach 8.Padlock of the present utility model also has 8 pins 9, and is corresponding one by one with 8 breach of bearing pin; Be with a groove 13 on each pin 9, groove 13 matches with the plane of bearing pin 3, that is to say, the width of groove 13 is slightly larger than the width on bearing pin plane; Pin also is provided with spring cave 14 at the groove back side can putting spring; Pin 9 and bearing pin 3 vertical settings, stretch out outside the lock body at its two ends, and lock body is marked with numeral and distinguishes each pin.
When the groove position of all pins 9 was consistent with bearing pin, because the width of groove is slightly larger than the width on bearing pin plane, bearing pin can move horizontally, and can utilize cooperating of its inclined-plane 7 and lock bridge inclined-plane 11 this moment, with lock bridge 1 pull-up or depress; When some pins snapped in the breach of bearing pin, bearing pin can not move, and locks lock bridge thus.And the relative position of groove 13 on pin 9 is uncertain, correctly regulates the position of pin, just can make groove be in correct position.Therefore be reflected in outside the lock body, push exactly after the pin of certain several position, lock bridge just can be opened, and after upset the position, lock bridge just can't be opened, and becomes coded lock and does not need key, can realize goal of the invention of the present utility model.
