Abstract

The utility model relates to a theft-proof padlock. A lock body comprises a lock front body and a lock rear body, a lock core is fixed with a lock top core, and a lock pin is arranged between the lock top core and a lock beam. The utility model which has the advantages of reasonable design for lock body not only eliminates the possibly that a lock core spring is dug out, but also enables the lock core not to be taken out of from the lock body. Besides, the right angles of the long support and the short support of the lock beam of the utility model are hung fixedly by lock pins, so the reliability of the theft-proof padlock is enhanced.

Description

Theftproof padlock

The utility model relates to a kind of spring padlock, particularly a kind of theft proof padlock.

Commercially available padlock adopts sloping type dead bolt structure to snap in the purpose of the half v-notch realization locking on the lock bridge at present.When this structure was subjected to bigger outer active force when lock bridge, dead bolt was drawn bad easily.For this reason, a kind of steel ball iron pad lock is disclosed among the Chinese patent CN2657203U.This is locked in and adorns 2 steel balls between lock core and the lock bridge, and lock bridge is drawn money on credit and lacked the inboard of propping up and all has the interior garden arc of setting steel ball.When lock bridge was subjected to external force, because of lock bridge is stuck in the lock body firmly by lock core and two steel balls between them, lock bridge can't be extracted in lock body, improves the reliability of lock thus like this.But because the enclosed construction of snap and the structure of fixed lock core be not improved, so padlock still exists unsafe factor.

The purpose of this utility model is to provide a kind of theft proof padlock of prizing and stealing can prevented effectively.

The purpose of this utility model realizes with following proposal: lock body is made up of lock precursor and lock back body, is fixed with the lock plunger tip on the lock core, between lock plunger tip and the lock bridge lock pin is housed, and lock bridge is drawn money on credit and lacked the through hole that Zhi Shangjun has symmetry and is positioned at a short end.

Have the groove that cooperates with lock core hole on the above-mentioned lock core.

The horizontal section of above-mentioned lock plunger tip is Z-shaped, the lock plunger tip by dowel fixes on lock core.

Above-mentioned lock precursor is established boss and buckle closure respectively with the edge of lock back body.

Elder generation is locking precursor or is locking in the body of back and put into lock core, lock bridge, lock plunger tip, lock pin, spring etc., and after sports association became one after will locking precursor and lock with bolt, that bolt two ends are polished was concordant with the lock body face again.

The utility model lock body is reasonable in design, has not only stopped the controlled core that may but also make that falls of lock core spring and can't take out in lock body.In addition, drawing money on credit and lacking Zhi Jun of the utility model lock bridge has lock pin that its right angle is hung extremely, so more strengthened the reliability of theft proof padlock.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the utility model structural representation.

As shown in Figure 1, lock body (5) divides the lock precursor and the lock back body of symmetry.The edge of lock precursor is established recessed, and lock bridge is drawn money on credit and established the location end face that matches with draw money on credit positioning boss and spring in the hole.With the location end face of setting the position spring in the vertical lock plunger tip hole that communicates of lock beam hole.Establish the tongue of fixed lock core in the lock core hole.The fixing spring end of drawing money on credit of lock bridge (1) is established boss, and places lock bridge to draw money on credit in the hole.The short end of lock bridge has and the corresponding through hole of drawing money on credit.Have with the corresponding groove of lock core hole on the lock core (4) and place in the lock core hole.Lock plunger tip (2) is by the upper surface of dowel fixes in lock core (4), and the horizontal section of lock plunger tip (2) is Z-shaped.Lock plunger tip (2) two be sidelong the latch (3) of putting two symmetries, mortise lock (3) but go up fixing spring.
