Description
Technical field
The utility model relates to a kind of insertion-core lock structure, specifically, relates to a kind of prying-resistant structure of insertion-core lock, belongs to five metals lockset product technical field.
Background technology
At present, the door lock that occurs on the market generally can be divided into two classes according to the use function of its handle, and a kind of is that handle is be used to the door lock that opens the door, closes the door purely, and the action of locking is finished by lock body and key thereof, and the door lock of this structure is comparatively common, but uses inconvenient; Another kind is that handle has both and opens the door, closes the door and the insertion-core lock of locking function, it mainly is made of lock body, dead bolt, lock core, fixed panel and the upper rotation handle that orders about the dead bolt action that arranges thereof, in the use procedure, retaining mechanism at dead bolt is under the open mode, handle downwards Arbitrary Rotation swings, and realizes opening the door action; If when carrying on the handle, handle can drive retaining mechanism bolt lock is fastened, and door lock is in locking state, and need to have key door could be opened this moment.The door lock of this structure opens the door, closes the door and locking function because its handle has both, and it is comparatively convenient to use, and usually is contained on indoor sleeved door, the security door, has become one of modal lockset on the market.
The utility model content
The purpose of this utility model provides a kind of prying-resistant structure of insertion-core lock, makes the use of insertion-core lock safer and convenient.
The prying-resistant structure of a kind of insertion-core lock described in the utility model comprises lock housing, latch bolt assembly and insurance hypistoma component, and described latch bolt assembly comprises latch bolt and latch bolt guide strip; It is characterized in that: described insurance hypistoma component comprises safety tongue, safety tongue support, safety tongue spring, fork, safety tongue pull bar and little torsion spring; Described safety tongue is located on the lock housing, is connected with the safety tongue pull bar; Described safety tongue support is fixed on the lock housing, and is set on the safety tongue pull bar and with the safety tongue pull bar and is slidingly connected; Described safety tongue spring housing is located on the safety tongue pull bar; Described fork is set on the fixed leg on the lock housing, and can be rotated around fixed leg; Described little torsion spring also is set on the fixed leg on the lock housing, and an end hook lives the latch bolt guide strip, and the other end hooks the flange of fork.
As a kind of preferred version, the hypotenuse of safety tongue pull bar contacts with the lower boss that turns over of fork, makes fork can be rotated clockwise to extreme position.
As further preferred version, the boss of fork contacts with the latch bolt guide strip, with being rotated counterclockwise of restriction fork.
When safety tongue is withstood by latch plate behind the door in the pass, present and insure namely pick-proof state, safety tongue moves right, and moves right on earth thereby drive the safety tongue pull bar, be separated with the hypotenuse that causes the safety tongue pull bar and the lower boss that turns over of fork, make fork be rotated counterclockwise extreme position; Therefore, after latch bolt moves right a bit of distance, can be limited by the front end of fork, so that can not continue to move right, thereby reach the purpose of pick-proof.
As seen, the prying-resistant structure of the insertion-core lock that the utility model provides has the advantages such as simple in structure, easy to operate, use safety, has practical value.
Description of drawings
Fig. 1 is the prying-resistant structure schematic diagram of described insertion-core lock.
Among the figure: 1, lock housing; 2, latch bolt; 3, latch bolt guide strip; 4, safety tongue; 5, safety tongue support; 6, safety tongue spring; 7, fork; 7.1, the flange of fork; 7.2, the lower boss that turns over of fork; 7.3, the boss of fork; 7.4, the front end of fork; 8, safety tongue pull bar; 8.1, the hypotenuse of safety tongue pull bar; 9, little torsion spring; 10, fixed leg.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is done further and to be elaborated:
As shown in Figure 1: the prying-resistant structure of a kind of insertion-core lock that the utility model provides, comprise lock housing 1, latch bolt assembly and insurance hypistoma component, described latch bolt assembly comprises latch bolt 2 and latch bolt guide strip 3; Described insurance hypistoma component comprises safety tongue 4, safety tongue support 5, safety tongue spring 6, fork 7, safety tongue pull bar 8 and little torsion spring 9; Described safety tongue 4 is located on the lock housing 2, is connected with safety tongue pull bar 8; Described safety tongue support 5 is fixed on the lock housing 2, and is set on the safety tongue pull bar 8 and with safety tongue pull bar 8 and is slidingly connected; Described safety tongue spring 6 is set on the safety tongue pull bar 8, and safety tongue 4 is resetted; Described fork 7 is set on the fixed leg 10 on the lock housing, and can be rotated around fixed leg 10; Described little torsion spring 9 also is set on the fixed leg 10 on the lock housing, and an end hook lives latch bolt guide strip 3, and the other end hooks the flange 7.1 of fork, makes fork 7 that a power that is rotated counterclockwise be arranged.
As a kind of preferred version, the hypotenuse 8.1 of safety tongue pull bar contacts with the lower boss 7.2 that turns over of fork, makes fork can be rotated clockwise to extreme position; Safety tongue support 5 can limit fork 7 to be continued to turn clockwise.
As further preferred version, the boss 7.3 of fork contacts with latch bolt guide strip 3, with being rotated counterclockwise of restriction fork 7.
Operating principle of the present utility model is as follows:
When safety tongue 4 is withstood by the latch plate (not shown) behind the door in the pass, present and insure namely pick-proof state, safety tongue 4 moves right, thereby driving safety tongue pull bar 8 moves right on earth, be separated with the hypotenuse 8.1 that the causes the safety tongue pull bar lower boss 7.2 that turns over fork, make fork 7 be rotated counterclockwise extreme position; Therefore, after latch bolt 2 moves right a bit of distance, can be limited by the front end 7.4 of fork, so that can not continue to move right, thereby reach the purpose of pick-proof.
In sum as seen: the prying-resistant structure of the insertion-core lock that the utility model provides, have the advantages such as simple in structure, easy to operate, use safety, have practical value.
Be necessary at last to be pointed out that at this; above-mentioned explanation only is used for the technical solution of the utility model is described in further detail; can not be interpreted as the restriction to the utility model protection domain, some nonessential improvement and adjustment that those skilled in the art makes according to foregoing of the present utility model all belong to protection domain of the present utility model.
