Description
Technical Field
The utility model relates to a spring bolt link gear.
Background
The triple lock tongue, the single-linkage lock tongue, the normally-locked lock tongue and the sky-ground hook are usually arranged on the lock, the triple lock tongue is used as a main locking mechanism, the single-linkage lock tongue is usually used as a back lock, no connection relation is formed between the single-linkage lock tongue and the lock cylinder, the normally-locked lock tongue is arranged in the door, and the normally-locked lock tongue always keeps a state of extending out of the lock body, so that a linkage mechanism is needed to drive the triple lock tongue, the single-linkage lock tongue and the sky-.
Disclosure of Invention
In view of the above, there is a need for a latch bolt linkage mechanism with simple structure and convenient use.
In order to solve the technical problem, the technical scheme of the utility model is that: a lock tongue linkage mechanism comprises a rotating shaft hinged on a lock body, wherein a first linkage plate and a second linkage plate are arranged on the rotating shaft, a first convex part for driving the first linkage plate to rotate is arranged at the upper part of the side wall of the rotating shaft, a groove for accommodating the first convex part is formed in the first linkage plate, the groove is larger than the first convex part, one end of the first linkage plate is connected with a return pull piece on a triple lock tongue, and the other end of the first linkage plate is connected with a normal lock tongue, so that when a key drives a lock core to rotate, the lock core stirs the return pull piece and unlocks the normal lock tongue; and the second linkage plate is provided with three shifting teeth, and a driving piece for linking the triple lock tongue is arranged between two adjacent shifting teeth.
The locking mechanism further comprises a third linkage plate arranged at the bottom of the second linkage plate, a second convex part for driving the third linkage plate to rotate is arranged at the lower part of the side wall of the rotating shaft, a groove for accommodating the second convex part is formed in the third linkage plate, the groove is larger than the second convex part, and one end of the third linkage plate is connected with a normally-locked locking dog.
Furthermore, a square through hole is formed in the middle of the rotating shaft and used for installing a handle.
Further, the second linkage plate and the rotating shaft are manufactured integrally.
Furthermore, the convex part and the rotating shaft are manufactured integrally.
Compared with the prior art, the utility model discloses following beneficial effect has: the linkage mechanism can quickly connect the triple lock tongue and the normal lock tongue on the lock body, and has the advantages of simple structure and convenient use.
In order to make the aforementioned and other objects, features and advantages of the present invention comprehensible, preferred embodiments accompanied with figures are described in detail below.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Fig. 2 is a schematic structural view of the embodiment of the present invention with the first linkage plate removed.
In the figure: 1-triple lock tongue, 11-return pull tab, 2-normal lock tongue, 3-rotating shaft, 31-first convex part, 4-first linkage plate, 41-groove, 5-second linkage plate, 51-shifting tooth, 6-third linkage plate, 7-driving piece and 8-another driving piece.
Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.
As shown in fig. 1-2, a lock tongue linkage mechanism comprises a rotating shaft 3 hinged on a lock body, wherein a first linkage plate 4 and a second linkage plate 5 are arranged on the rotating shaft, a first convex part 31 for driving the first linkage plate to rotate is arranged at the upper part of the side wall of the rotating shaft, a groove 41 for accommodating the first convex part is arranged on the first linkage plate, the groove is larger than the first convex part, one end of the first linkage plate is connected with a return pull piece on a triple lock tongue, and the other end of the first linkage plate is connected with a normal lock tongue, so that when a key drives a lock core to rotate, the lock core stirs the return pull piece and unlocks the normal lock; the second linkage plate is provided with three shifting teeth 51, and a driving piece for linkage of a triple lock tongue is arranged between two adjacent shifting teeth.
In this embodiment, one driving member 7 is used to drive the triple lock tongue to move left and right, and the other driving member 8 is used to control the extension length of the triple lock tongue.
In this embodiment, the locking device further comprises a third linkage plate 6 arranged at the bottom of the second linkage plate, a second convex part for driving the third linkage plate to rotate is arranged at the lower part of the side wall of the rotating shaft, a groove for accommodating the second convex part is arranged on the third linkage plate, the groove is larger than the second convex part, and one end of the third linkage plate is connected with a normally-locked bolt. The third linkage plate has the function of assisting the first linkage plate to drive the normally-locked bolt.
In this embodiment, a square through hole is formed in the middle of the rotating shaft for mounting a handle.
In this embodiment, the second link plate is integrally formed with the rotating shaft.
In this embodiment, the protruding portion and the rotating shaft are integrally formed.
The recess is greater than the convex part for the pivot has an empty stroke when rotating, and then makes the spring bolt of lock body can not move simultaneously, avoids taking place to interfere.
The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention has been disclosed by the preferred embodiment, it is not limited to the present invention, and any person skilled in the art can make modifications or changes equivalent to the equivalent embodiments by utilizing the above disclosed technical contents without departing from the technical scope of the present invention, but all the modifications, changes and changes of the technical spirit of the present invention made to the above embodiments are also within the scope of the technical solution of the present invention.
