Description
Technical field
It the utility model is related to ground hook lock technical field, more particularly to a kind of Antiprizing rolled gate ground hook lock.
Background technology
Ground hook lock used in shutter door mainly by with the ground hook clamping on OR gate frame located underground to lock.Due to ground hook
Lock body product is big, complicated, with having some gaps in the engagement process of ground hook, has accordingly increased the wind that ground hook lock is prized
Danger.Therefore need to reduce the possibility that strength member is pried open in ground hook lock tapered end, while require closing component structure in increase ground hook lock
Quantity, shutter door can not still be opened after partly being pried open, coordinate warning device can play more preferable pick-proof and anti-theft effect.
Utility model content
A kind of the purpose of this utility model with being to provide for two-part shutter door with good tamper-resistant function hook lock.It is logical
Cross and set guide groove to coordinate the second shifting block to realize the clamping to dead bolt to realize the purpose in cross-brace.
In order to reach the purpose, the utility model adopts the following technical scheme that：Including lock housing and in the lock housing
Cross-brace, be provided with guide groove along the cross-brace activity direction in the cross-brace, limited screw be provided with the guide groove,
It is characterized in that：
Also include be hinged dead bolt, the first shifting block and the second shifting block being arranged in the lock housing, the dead bolt is provided with the
One limiting section and the second limiting section, are provided with extension spring between the dead bolt and first shifting block and second shifting block, and described
One shifting block side is provided with the limited block for limiting its activity amplitude；
Second shifting block, which includes the phase support coordinated with second limiting section and follower, the follower, to be included
Turning arm and the cylindrical jacking block positioned at the turning arm end；
The cross-brace lower end is provided with convex portion, stopper slot is offered in the cross-brace, the jacking block is positioned at described spacing
In groove, the stopper slot include the first side vertical with the cross-brace direction of motion and close to the extension spring side with
The vertical second side in the first side.
Thus, stopper slot drives and limits the scope of activities of the second shifting block, realized jointly with dead bolt ground hook lock locking with
Open.
As a preferred embodiment, being shaped as the guide groove is square.
As a preferred embodiment, fillet is provided between the first side and the second side.
Thus, jacking block is avoided by being stuck during guide groove adjacent side intersection.
As a preferred embodiment, the diameter of the fillet is more than the diameter of the jacking block.
As a preferred embodiment, when the jacking block offsets with the second side, the first side is between the jacking block
Distance is more than the convex portion to the distance of first shifting block and the limited block contact position.
Thus, when driving cross-brace unlocking, convex portion first contacts with the first shifting block and rotates the first shifting block.
As a preferred embodiment, the angle between the phase support and the follower is between 75 ° to 105 °.
To sum up, the utility model has advantages below：The guide groove opened up in cross-brace promotes the second shifting block to rotate and limit
Make it and rotate amplitude, avoid the perforate in lock housing, and then improve security.
Brief description of the drawings
Fig. 1 is a kind of structural representation of embodiment of the utility model；
The first example structure schematic diagram that Fig. 2 is dead bolt and cross-brace coordinates.
Label in figure is as follows：
1. lock housing, 2. cross-braces, 21. guide grooves, 22. limited screws, 23. convex portions, 24. stopper slots, 241. first sides,
242. second sides, 3. dead bolts, 31. first limiting sections, 32. second limiting sections, 4. first shifting blocks, 5. second shifting blocks, 51. offset
Portion, 52. followers, 521. turning arms, 522. jacking blocks, 6. extension springs, 7. limited blocks.
Embodiment
The utility model is described in further detail for middle embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, the ground hook lock includes the cross-brace 2 in lock housing 1 and lock housing 1, lived in cross-brace 2 along cross-brace 2
Dynamic direction is provided with guide groove 21, and limited screw 22 is provided with guide groove 21.It is hinged in lock housing 1 and is provided with dead bolt 3, the first shifting block 4
With the second shifting block 5, dead bolt 3 is provided with the first limiting section 31 and the second limiting section 32.When ground hook lock is in locking state, the first limit
The shifting block 4 of position portion 31 and first offsets, and the second shifting block 5 is located on the event trace of the second limiting section 32.The shifting block 4 of dead bolt 3 and first
And second be provided with extension spring 6 between shifting block 5, the side of the first shifting block 4 is provided with the limited block 7 for limiting its activity amplitude.Second shifting block 5 wraps
The phase support 51 coordinated with the second limiting section 32 and follower 52 are included, follower 52 includes turning arm 521 and positioned at rotation
The cylindrical jacking block 522 of the end of arm 521.
The lower end of cross-brace 2 is provided with convex portion 23, and limited location groove 24 is offered in cross-brace 2, and jacking block 522 is located at stopper slot 24
Interior, the stopper slot 24 includes the first side 241 vertical with the direction of motion of cross-brace 2 and close to the extension spring 6 one
The second side 242 vertical with the first side 241 of side.During unlocking, in the motion process of stopper slot 24, jacking block 522
Second side 242 is slid into being slided behind the intersection of first side 241 along first side 241 along second side 242, now second
Shifting block 5 starts to rotate, until departing from locking mated condition with dead bolt 3.
Being shaped as stopper slot 24 is square.When jacking block 522 offsets with second side 242, jacking block 522 is arrived in first side 241
Between distance be more than distance between the shifting block of convex portion 23 to the first 4 and the contact position of limited block 7.Therefore, driving cross-brace 2 is unlocked
When, convex portion 23 first contacts with the first shifting block 4 and rotates the first shifting block 4, after the first shifting block 4 disengages with dead bolt 3, second group
Block 5 separates final unlatching ground hook lock in the presence of first side 241 with dead bolt 3, adds the difficulty for prying open lock.
As shown in Fig. 2 fillet is provided between first side 241 and second side 242, to avoid jacking block 522 by limiting
It is stuck during the 24 adjacent side intersection of groove of position.The diameter of fillet is more than the diameter of jacking block 522, ensures the fluency of the activity of jacking block 522.
52 angle is between 75 ° to 105 ° between phase support 51 and follower, ensure the rotary shaft of the shifting block of jacking block 522 to the second 5 away from
From avoiding the width of cross-brace 2 excessive.
Described above is only to explanation of the present utility model so that those of ordinary skill in the art's can completely implements this
Scheme, but be not to limitation of the present utility model, those skilled in the art can be as needed after this specification is read
The modification of no creative contribution is made to the present embodiment, these are all without creative modification.But as long as in this practicality
All protected in new right by Patent Law.
