Abstract
The utility model discloses a mortise lock structure for enabling a key to drive the retraction of a latch bolt. The mortise lock structure comprises a lock case, a latch bolt assembly, a shifting sheet and an I-shaped shifting fork, wherein the I-shaped shifting fork is sheathed on a fixed column on the lock case and can rotate around the fixed column. When the key drives the shifting sheet to clockwise rotate, the I-shaped shifting fork can be further driven to anticlockwise rotate; the I-shaped shifting fork can further drive the latch bolt to move rightwards to realize the retraction of the latch bolt. The mortise lock structure for enabling the key to drive the retraction of the latch bolt, which is provided by the utility model, has the advantages of simple structure, convenience in operation and practical value.
Description
Technical field
The utility model relates to a kind of insertion-core lock structure, specifically, relates to a kind of insertion-core lock structure that realizes that the key actuated latch bolt is retracted, and 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 insertion-core lock structure that realizes that the key actuated latch bolt is retracted, and makes the designs simplification of insertion-core lock and use more convenient.
A kind of insertion-core lock structure that realizes that the key actuated latch bolt is retracted described in the utility model comprises lock housing and latch bolt assembly; It is characterized in that: also comprise plectrum and I-shaped shift fork, described I-shaped shift fork is set on the fixed leg on the lock housing, and can be rotated around fixed leg.
As a kind of preferred version, described latch bolt assembly comprises latch bolt, latch bolt pull bar, latch bolt front spring, latch bolt guide strip, the U-shaped seat of latch bolt and latch bolt rear spring, described latch bolt is connected with the latch bolt pull bar, described latch bolt front spring, latch bolt guide strip, the U-shaped seat of latch bolt and latch bolt rear spring all are set on the latch bolt pull bar, and latch bolt front spring, the U-shaped seat of latch bolt and latch bolt rear spring all are slidingly connected with the latch bolt pull bar, and described latch bolt guide strip is fixed on the lock housing.
As further preferred version, the front end of described I-shaped shift fork can contact with the U-shaped seat of latch bolt.
When key drive plectrum turns clockwise, can further take the I-shaped shift fork to and do and be rotated counterclockwise, the front end of I-shaped shift fork can contact with the U-shaped seat of latch bolt, moves right thereby drive the U-shaped seat of latch bolt, so that further drive latch bolt and move right, realize the latch bolt retraction; When unclamping key, the latch bolt front spring can make latch bolt reset.
As seen, the insertion-core lock structure that the realization key actuated latch bolt that the utility model provides is retracted has the advantages such as simple in structure, easy to operate, has practical value.
Description of drawings
Fig. 1 is the structural representation of described insertion-core lock when latch bolt is stretched out state;
Fig. 2 is the structural representation of described insertion-core lock when key retraction latch bolt state.
Among the figure: 1, lock housing; 2, latch bolt; 3, latch bolt pull bar; 4, latch bolt front spring; 5, latch bolt guide strip; 6, the U-shaped seat of latch bolt; 7, latch bolt rear spring; 8, plectrum; 9, I-shaped shift fork; 9.1, the front end of I-shaped shift fork; 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 depicted in figs. 1 and 2: a kind of insertion-core lock structure that realizes that the key actuated latch bolt is retracted described in the utility model comprises lock housing 1, latch bolt assembly, plectrum 8 and I-shaped shift fork 9; Described latch bolt assembly comprises latch bolt 2, latch bolt pull bar 3, latch bolt front spring 4, latch bolt guide strip 5, the U-shaped seat 6 of latch bolt and latch bolt rear spring 7, described latch bolt 2 is connected with latch bolt pull bar 3, described latch bolt front spring 4, latch bolt guide strip 5, the U-shaped seat 6 of latch bolt and latch bolt rear spring 7 all are set on the latch bolt pull bar 3, and latch bolt front spring 4, the U-shaped seat 6 of latch bolt and latch bolt rear spring 7 all are slidingly connected with latch bolt pull bar 3, and described latch bolt guide strip 5 is fixed on the lock housing 2; Described I-shaped shift fork 9 is set on the fixed leg 10 on the lock housing 2, and can be rotated around fixed leg 10.
As a kind of preferred version, the front end 9.1 of described I-shaped shift fork can contact with the U-shaped seat 6 of latch bolt.
Operating principle of the present utility model is as follows:
When key drive plectrum 8 turns clockwise, can further take I-shaped shift fork 9 to and do and be rotated counterclockwise, the front end 9.1 of I-shaped shift fork can contact with the U-shaped seat 6 of latch bolt, moves right thereby drive the U-shaped seat 6 of latch bolt, so that further drive latch bolt 2 and move right, realize latch bolt 2 retractions; When unclamping key, latch bolt front spring 4 can make latch bolt 2 reset.
In sum as seen, the insertion-core lock structure that the realization key actuated latch bolt that the utility model provides is retracted has the advantages such as simple in structure, easy to operate, has 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.
