Abstract

The utility model discloses a mortise lock structure capable of reversing a latch bolt. The mortise lock structure comprises a lock case and a latch bolt assembly, wherein the latch bolt assembly comprises a latch bolt, a latch bolt pull rod, a latch bolt front spring, a latch bolt guide plate, a latch bolt U-shaped seat and a latch bolt rear spring. The latch bolt is connected with the latch bolt pull rod by a pin; the latch bolt front spring, the latch bolt guide plate, the latch bolt U-shaped seat and the latch bolt rear spring are sleeved on the latch bolt pull rod in sequence; the latch bolt front spring, the latch bolt U-shaped seat and the latch bolt rear spring are all connected with the latch bolt pull rod in a sliding manner; and the latch bolt guide plate is fixed on the lock case. According to the mortise lock structure, the latch bolt is connected with the latch bolt pull rod by the pin, when moving towards the left to exceed the lock case, the latch bolt can be rotated arbitrarily; after being rotated to be abreast with the lock case, the latch bolt is loosened, and can be reset by using the latch bolt rear spring, so that the latch bolt is reversed. The mortise lock structure is simple in structure, convenient to operate, flexible in use and the like.

Description

A kind of insertion-core lock structure that realizes Inclined bolt direction changing

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 Inclined bolt direction changing, 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 Inclined bolt direction changing, makes the use of insertion-core lock more convenient and flexible.

A kind of insertion-core lock structure that realizes Inclined bolt direction changing described in the utility model, comprise lock housing and latch bolt assembly, it is characterized in that: described latch bolt assembly comprises latch bolt, the latch bolt pull bar, the latch bolt front spring, the latch bolt guide strip, the U-shaped seat of latch bolt and latch bolt rear spring, described latch bolt is connected by pin with the latch bolt pull bar, described latch bolt front spring, the latch bolt guide strip, the U-shaped seat of latch bolt and latch bolt rear spring are set on the latch bolt pull bar successively, 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.

Because latch bolt is connected by pin with the latch bolt pull bar, after latch bolt is moved beyond lock housing to the left, can rotate arbitrarily, when rotating to and unclamping after lock housing is concordant, can utilize the latch bolt rear spring that latch bolt is resetted, thereby can realize Inclined bolt direction changing.

The insertion-core lock structure that the utility model provides can realize Inclined bolt direction changing, has simple in structurely, easy to operate, uses the advantages such as flexible, has practical value.

Description of drawings

Fig. 1 has shown the structural representation of the latch bolt assembly in the described insertion-core lock structure;

Fig. 2 has shown the structural representation of latch bolt when commutation states of described insertion-core lock;

Fig. 3 has shown the structural representation of latch bolt after commutation of described insertion-core lock.

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, pin.

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 to Figure 3: the insertion-core lock structure that the utility model provides, comprise lock housing 1 and latch bolt assembly, 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 by pin 8 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 are set on the latch bolt pull bar 3 successively, 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 1.

In sum as seen: the insertion-core lock structure that the utility model provides, can realize Inclined bolt direction changing, have simple in structurely, easy to operate, use the advantages such as flexible, 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.
