Description
Technical Field
The invention relates to the technical field of ground hook locks, in particular to a prying-resistant ground hook lock of a rolling door.
Background
The ground hook lock used by the rolling gate is mainly clamped and connected with a ground hook positioned underground or on a door frame to be locked. Because ground hook lock is bulky, the structure is complicated, has some gaps in the cooperation process with the ground hook, corresponding increase ground hook lock the risk of being prized. Therefore, the possibility that important parts in the ground hook lock head are prized is reduced, the number of locking structures in the ground hook lock is required to be increased, the rolling door cannot be opened after the rolling door is partially prized, and a better anti-prying and anti-theft effect can be achieved by matching with an alarm device.
Disclosure of Invention
The invention aims to provide a two-section type rolling gate ground hook lock with a good anti-prying function. This purpose is realized to the chucking of spring bolt through set up the guide way cooperation second shifting block on the cross-brace.
In order to achieve the purpose, the invention adopts the following technical scheme: including the lock shell and be located the cross brace in the lock shell, follow on the cross brace activity direction is opened there is the guide way, be equipped with spacing screw, its characterized in that in the guide way:
the lock is characterized by further comprising a spring bolt, a first shifting block and a second shifting block which are hinged in the lock shell, wherein the spring bolt is provided with a first limiting part and a second limiting part, tension springs are arranged among the spring bolt, the first shifting block and the second shifting block, and a limiting block for limiting the activity amplitude of the first shifting block is arranged on one side of the first shifting block;
the second shifting block comprises an abutting part and a driven part which are matched with the second limiting part, and the driven part comprises a rotating arm and a cylindrical top block positioned at the end part of the rotating arm;
the stop block is positioned in the limit groove, and the limit groove comprises a first side edge perpendicular to the motion direction of the cross brace and a second side edge close to one side of the tension spring and perpendicular to the first side edge.
Therefore, the limiting groove drives and limits the moving range of the second shifting block, and the locking and unlocking of the ground hook lock are realized together with the lock tongue.
Preferably, the guide groove has a square shape.
Preferably, a rounded corner is provided between the first side edge and the second side edge.
Therefore, the top block is prevented from being clamped when passing through the intersection of the adjacent sides of the guide groove.
Preferably, the diameter of the fillet is larger than the diameter of the top block.
Preferably, when the top block abuts against the second side edge, the distance from the first side edge to the top block is greater than the distance from the convex part to the contact position of the first shifting block and the limiting block.
Therefore, when the cross brace is driven to unlock, the convex part is firstly contacted with the first shifting block and rotates the first shifting block.
Preferably, the included angle between the abutting portion and the driven portion is between 75 ° and 105 °.
In conclusion, the invention has the following advantages: the guide groove that sets up on the cross brace promotes the rotation of second shifting block and restricts its amplitude of rotation, has avoided trompil on the lock shell, and then has improved the security.

The reference numbers in the figures are as follows:
1. the lock comprises a lock shell, 2 parts of a cross brace, 21 parts of a guide groove, 22 parts of a limiting screw, 23 parts of a convex part, 24 parts of a limiting groove, 241 parts of a first side edge, 242 parts of a second side edge, 3 parts of a lock tongue, 31 parts of a first limiting part, 32 parts of a second limiting part, 4 parts of a first shifting block, 5 parts of a second shifting block, 51 parts of an opposite part, 52 parts of a driven part, 521 parts of a rotating arm, 522 parts of a top block, 6 parts of a tension spring and 7 parts of a limiting block.
Detailed Description
The invention will be further elucidated with reference to an embodiment in the drawing.
As shown in figure 1, the ground hook lock comprises a lock shell 1 and a cross brace 2 arranged in the lock shell 1, wherein a guide groove 21 is formed in the cross brace 2 along the moving direction of the cross brace 2, and a limit screw 22 is arranged in the guide groove 21. The lock shell 1 is internally hinged with a lock bolt 3, a first shifting block 4 and a second shifting block 5, and the lock bolt 3 is provided with a first limiting part 31 and a second limiting part 32. When the ground hook lock is in a locking state, the first limiting part 31 abuts against the first shifting block 4, and the second shifting block 5 is located on a moving track of the second limiting part 32. A tension spring 6 is arranged between the lock tongue 3 and the first shifting block 4 as well as the second shifting block 5, and a limiting block 7 for limiting the activity amplitude of the first shifting block 4 is arranged on one side of the first shifting block. The second shifting block 5 includes an abutting portion 51 and a driven portion 52 matched with the second limiting portion 32, and the driven portion 52 includes a rotating arm 521 and a cylindrical top block 522 located at an end portion of the rotating arm 521.
The lower extreme of cross brace 2 is equipped with convex part 23, has seted up a spacing groove 24 on the cross brace 2, and kicking block 522 is located the spacing groove 24, the spacing groove 24 include with 2 direction of motion vertically first sides 241 of cross brace and be close to on one side of extension spring 6 with first side 241 vertically second side 242. During unlocking, in the movement process of the limiting groove 24, the top block 522 slides along the second side edge 242 to the intersection of the second side edge 242 and the first side edge 241 and then slides along the first side edge 241, and at this time, the second shifting block 5 starts to rotate until being separated from the locking matching state with the lock bolt 3.
The shape of the limiting groove 24 is square. When the top block 522 abuts against the second side edge 242, the distance between the first side edge 241 and the top block 522 is greater than the distance between the convex part 23 and the contact position of the first shifting block 4 and the stop block 7. Therefore, when the cross brace 2 is driven to unlock, the convex part 23 firstly contacts with the first shifting block 4 and rotates the first shifting block 4, and after the first shifting block 4 is separated from the lock tongue 3, the second shifting block 5 is separated from the lock tongue 3 under the action of the first side edge 241 to finally unlock the ground hook lock, so that the difficulty in picking the lock is increased.
As shown in fig. 2, a rounded corner is formed between the first side 241 and the second side 242 to prevent the top block 522 from being locked when passing through the intersection of the adjacent sides of the limiting groove 24. The diameter of the fillet is greater than the diameter of the top block 522, and the smoothness of the movement of the top block 522 is guaranteed. The included angle between the abutting part 51 and the driven part 52 is 75-105 degrees, so that the distance from the top block 522 to the rotating shaft of the second shifting block 5 is ensured, and the overlarge width of the cross brace 2 is avoided.
The above description is only for explaining the present invention, so that the person skilled in the art can fully implement the present invention, but not for limiting the present invention, and after reading the present specification, the person skilled in the art can make modifications without inventive contribution to the present embodiment, which are all non-inventive modifications. But are protected by the patent statutes within the scope of the appended claims.
