The padlock with a protective housing comprises a lock body 1, a lock beam 2, a lock bolt 3, a lock core 4 and a spring set 5. The utility model has the main point that the outer part of the lock body 1 is provided with a protective housing 6 corresponding to the shape of the lock body, and the protective housing 6 is made of hard metal materials, is in a split assembly type and is formed by assembling at least two split housings. The utility model has a strong anti-sabotage function and has higher safety and reliability than that of the common padlock.
Description
The utility model relates to a kind of padlock, particularly relates to a kind of padlock with guard shield that can prevent artificial destruction.
In people's life, many occasions all will be used padlock.The safety of padlock will be directly connected to the safety of employed equipment or facility.As being used for the padlock of occasions such as warehouse or container in case destroyed by the people and to cause stolenly, its economic loss is huge often.Thereby people are very high to use in the security requirement of the padlock of these important events.The padlock that generally uses all partly is made up of lock body, lock bridge, dead bolt, lock core and pellet shot from a slingshot group etc. at present, and the material of making padlock, except that lock bridge by the manufacturing of hard steel, remainder mostly is raw material with brass, this material that mainly is based on brass is softer relatively, stable chemical performance can be because of the corrosion of exposing to the sun and rain, the performance of influence lock.Because brass is soft material, and common padlock all lacks safeguard structure, thereby be easy to be damaged (as brill, saw etc.).
The purpose of this utility model is to provide a kind of can resist stronger mechanical damage power, thereby the padlock that safety is improved greatly.
For achieving the above object, the utility model provides a kind of padlock with guard shield, this padlock comprises lock body 1, lock bridge 2, dead bolt 3, lock core 4 and pellet shot from a slingshot group 5, and main points of the present utility model are to be provided with in lock body 1 outside a corresponding guard shield 6 of shape with it.
Described guard shield 6 is made by hard metal material, and is assembled, is assembled by at least two branch body case.
Because the utility model is provided with a guard shield outside the padlock of basis brass system, so not only kept the advantage of the stable chemical performance of brass, strengthened the security performance of lock again greatly, especially as having put on a dress shield for padlock.Repeatedly destructive testing proves, guard shield can be resisted stronger mechanical damage power, for example, all is difficult for penetrating guard shield with the hacksaw saw or with the electric hand drill brill, therefore this lockset has stronger anti-destruction function, and all more common padlock of its safety and reliability improves greatly.
Fig. 1 is the utility model profile schematic diagram.
Fig. 2 is the utility model structural representation.
Fig. 3 is guard shield and lock body decomposing schematic representation.
As shown in Figure 2, the utility model comprises lock body 1, lock bridge 2, dead bolt 3, lock core 4 and pellet shot from a slingshot group 5, and wherein, lock body 1 is made by brass, and lock bridge 2 is made by hard metal material.For strengthening the survivability of latching surface, be provided with a corresponding guard shield 6 of shape with it in lock body 1 outside, lock body is coated fully.Guard shield is made by hard metal material, and in this example, guard shield is made by electroplating steel plate.For ease of assembling, guard shield adopts assembled, its minute body structure as shown in Figure 3, it is made up of four branch body case 61,62,63,64, wherein, branch body case 61,62 is by inserting the projection on its inwall 611,621 left and right sides of being fixed in lock body in the corresponding groove 11,12 on the lock body.Divide body case 63 by in the groove 13 that the projection on its inwall 631 is inserted on the lock body, and be fixed in the indentation, there that lock bridge 2 is housed by rivet 7.64 of branch body case are enclosed within it on lock body after installing above-mentioned three branch body case, and fix with lock body in its bottom by rivet 8.Like this, just each face of lock body is coated fully with steel plate by guard shield.
The utility model operating principle can be referring to Fig. 2, and when 41 arrangements of spoon tooth met predefined password, pellet shot from a slingshot group 5 was concordant with lock core 4 faces of cylinder, and lock core just can change, and the projection 42 of lock core is pressed dead bolt 3, and lock bridge 2 is released ejection, and lock is opened.
Prove that through test of many times the hard protection shell can be resisted stronger mechanical damage power.For example, bore guard shield, all be difficult for drilling shell with the hacksaw saw or with electric hand drill.If the burglar wants with the key hole brill lock core of electric drill from lock, though drill bit can pierce in the lock core, but pellet shot from a slingshot group 5 is covered in by the key hole 65 that two scallop holes are formed, drill bit can not thoroughly be destroyed constitute the pellet shot from a slingshot group of opening coded lock, pellet shot from a slingshot can not thoroughly destroy, the nature lock core just can not rotate, and lock bridge 2 just can not be opened.
