CN2339709Y - Reinforced tension ped lock - Google Patents

Abstract

The utility model relates to a reinforced type tensioning resistant padlock which comprises a lock body 1, a lock beam 2 and a dead bolt 3. The utility model is characterized in that compared with the ordinary padlock, the diameter of lock beam 2 and the dead bolt 3 can be increased form 1 mm to 6 mm; the locking plane 31 of the dead bolt is positioned below the shaft line of the cylinder of the dead bolt. Compared with the ordinary padlock with the same specification, the padlock of the utility model has the advantages that the average tensioning resistant strength can be more than 14KN, and is 1.5 times as strong as the ordinary padlock. The safety performance of the utility model can be improved because the tensioning resistant strength is improved.

Description

Reinforced tension padlock

The utility model relates to a kind of padlock, particularly relates to the high reinforced tension padlock of a kind of tensile strength.

Padlock is the most widely used a kind of lock during people live, and it is widely used in multiple occasion.Any one user wishes to select a kind of safety factor height when purchasing lock, promptly is not easy the product that is opened or destroys.And the security performance quality of padlock, one of its leading indicator is the size of the tensile strength values between lock bridge 2 and the lock body 1.Tensile strength is big more, and its security performance is good more.Here the tensile strength of indication is actually the value of defining to the destructive tensile test of lock.The citation form of the tensile test of padlock as shown in Figure 1.Present commercially available various padlocks, the diameter of its lock bridge and dead bolt is all thinner, thereby tensile strength is all lower, and security performance is relatively poor.

The utility model is exactly to improve at the low defective of common padlock tensile strength, and purpose is to provide a kind of structure very simple, the padlock that tensile strength and security performance improve greatly.

For achieving the above object, the utility model provides a kind of reinforced tension padlock, this padlock comprises lock body 1, lock bridge 2 and dead bolt 3, it is characterized in that the general padlock overstriking 1～6mm of diameter of lock bridge 2 and dead bolt 3, and the lock plane 31 of dead bolt is under the dead bolt cylinder axis.

The utility model by padlock being born pulling force critical piece one lock bridge and the architecture advances of dead bolt, the tensile strength of padlock is strengthened greatly, with the wide padlock of traditional 40mm is example, its average tensile strength has only 9.3KN, and same specification padlock of the present utility model, average tensile strength reaches more than the 14KN, is 1.5 times of common padlock.Because tensile strength improves greatly, thereby its security personnel's performance has also improved greatly.

Fig. 1 is a padlock tensile test schematic diagram.

Fig. 2 is the utility model overall structure schematic diagram.

Fig. 3 is the utility model dead bolt structural representation.

Fig. 4 is that common padlock dead bolt and the utility model dead bolt compare schematic diagram.

Provide embodiment of the present utility model below in conjunction with accompanying drawing.

As shown in Figure 2, the utility model comprises lock body 1, lock bridge 2 and dead bolt 3, and wherein lock bridge 2 and dead bolt 3 are the critical pieces that bear pulling force.In order to increase the tensile strength of padlock, the utility model is with the diameter of lock bridge and the dead bolt general padlock overstriking 1～6mm than same specification, and two lock plane 31 of a pair of dead bolt are under the dead bolt cylinder axis.Fig. 3 has shown the basic structure of dead bolt, and Fig. 4 has then provided the comparison of the structure of itself and traditional dead bolt.By diagram, the lock plane of traditional dead bolt is in half of dead bolt cylinder, and dead bolt of the present utility model plane then is under the dead bolt cylinder axis.This just makes the cross-sectional area at two lock plane 31 places of dead bolt increase, thereby has increased tensile strength.Equally, the overstriking of lock bridge diameter has also increased the cross section and the tensile strength thereof of lock bridge.

Can further understand operating principle of the present utility model in conjunction with Fig. 2, when buckling padlock, two concave surfaces 11 of lock bridge are pinned by a pair of dead bolt 3.Two lock plane 31 of dead bolt are tightly blocked lock bridge 2.When lock bridge and lock body bore pulling force, two lock plane of dead bolt just were delivered to pulling force on the lock body 1.When pulling force increases to when being enough to make dead bolt 3, lock bridge 2 and lock body 1 to produce permanent deformation or fracture, just reached ultimate tension.The utility model then makes the ultimate tension of padlock improve greatly.

Claims (1)

1, a kind of reinforced tension padlock comprises lock body (1), lock bridge (2) and dead bolt (3), it is characterized in that the general padlock overstriking 1～6mm of diameter of lock bridge (2) and dead bolt (3), and the lock plane of dead bolt (31) is under the dead bolt cylinder axis.
