Description
Technical field:
The utility model belongs to the safe-guard door lock technical field, especially relates to a kind of main dead bolt rotational structure of safe-guard door lock.
Background technology:
Existing safe-guard door lock generally can be provided with multiple dead bolt on lock body; But wherein shoulder the still main dead bolt of main antitheft effect; And the structure that present main dead bolt normally adopts a plurality of straight bolts to be connected in parallel, when locking a door, the interior realization of lockhole that each straight bolt directly is inserted into doorframe locks.The shortcoming of this main dead bolt structure is to be pried open by robber's recruitment tool easily, the pick-proof poor performance, thereby await improving.
The utility model content:
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, and the main dead bolt rotational structure of a kind of compact conformation, safe-guard door lock that the pick-proof performance is strong is provided.
For realizing the foregoing invention purpose, the utility model has adopted following technical scheme:
A kind of main dead bolt rotational structure of safe-guard door lock; Comprise lock body, panel and be arranged on the main dead bolt parts in the lock body; Also comprise the transverse slider that can in lock body, laterally slide; Transverse slider is provided with the first vertical chute and the second vertical chute, and the upper end of the first vertical chute is connected with an oblique chute; Said main dead bolt parts comprise rotation tongue, dead bolt, rotation tongue locating shaft, main bolt plate and deflecting plate; Wherein, It is affixed through rivet with rotation tongue locating shaft that rotating shaft one end of rotation tongue passes dead bolt; Be fixedly connected between dead bolt and the main bolt plate, the transverse slider guide finger that is set with the deflecting plate alignment pin on the main bolt plate and cooperates with the first vertical chute and oblique chute, deflecting plate are provided with deflecting plate chute that cooperates with the deflecting plate alignment pin and the deflecting plate guide finger that cooperates with the second vertical chute; Rotation tongue locating shaft is provided with the pendulum wing, also is provided with and puts the rotation tongue locating shaft guide finger that the wing is connected on the deflecting plate.
Said rotation tongue is made up of tongue body that is waist shape and said rotating shaft, and said dead bolt is straight tongue structure, offers the axis hole that supplies said rotating shaft to pass on it.
Said rotation tongue locating shaft is the cylindrical body that circumferencial direction is provided with opening, and its openend both sides stretch out and form the said pendulum wing, and said rotation tongue locating shaft guide finger embeds and should put in the wing.
The upper end of said deflecting plate is extended with a vertical portion downwards, and said rotation tongue locating shaft guide finger is arranged in this vertical portion.
Said transverse slider is provided with its horizontal concrete chute that laterally slides of some confessions, and the corresponding site in the said lock body is provided with the guide finger that cooperates with each horizontal concrete chute.
The utility model has following advantage with respect to prior art:
The main dead bolt of the utility model is made up of dead bolt and rotation tongue, and when locking a door, dead bolt is inserted in the lockhole of doorframe with the rotation tongue together; Simultaneously, the rotation tongue revolves and turn 90 degrees, and makes its wide end snap onto the lockhole inboard; Thereby can avoid the robber to use tamper tool, improve the pick-proof performance of main dead bolt.In addition, this main dead bolt rotational structure compact and reasonable can be saved the space, reduces the lock body volume, thereby reduces cost.
Description of drawings:
Fig. 1 is in the structural representation of unlocking condition for the utility model.
The structural representation that Fig. 2 is in the lock state for the utility model.
Fig. 3 is the exploded perspective view of main dead bolt parts in the utility model.
The specific embodiment:
Referring to Fig. 1, Fig. 2 and Fig. 3, as a kind of preferred embodiment of the utility model, the main dead bolt rotational structure of this safe-guard door lock comprises: lock body 1, panel 2 is arranged on the transverse slider 4 that the main dead bolt parts 3, in the lock body 1 can laterally slide in lock body 1.The upper end that transverse slider 4 is provided with the first vertical chute 41 and second vertical chute 42, the first vertical chutes 41 is connected with an oblique chute 41a.Main dead bolt parts 3 comprise rotation tongue 31, dead bolt 32, rotation tongue locating shaft 33, main bolt plate 34 and deflecting plate 35; Wherein, It is affixed through rivet with rotation tongue locating shaft 33 that rotating shaft 311 1 ends of rotation tongue 31 pass dead bolt 32; Be fixedly connected between dead bolt 32 and the main bolt plate 34; The transverse slider guide finger 342 that is set with deflecting plate alignment pin 341 on the main bolt plate 34 and cooperates with the first vertical chute 41 and oblique chute 41a; Deflecting plate 35 is provided with deflecting plate chute 351 that cooperates with deflecting plate alignment pin 341 and the deflecting plate guide finger 352 that cooperates with the second vertical chute 42, and rotation tongue locating shaft 33 is provided with the pendulum wing 331, also is provided with and puts the rotation tongue locating shaft guide finger 353 that the wing 331 is connected on the deflecting plate 35.
The upper end of deflecting plate 35 is extended with a vertical portion 354 downwards, and rotation tongue locating shaft guide finger 353 is arranged in this vertical portion 354.Transverse slider 4 is provided with its horizontal concrete chute 43 that laterally slides of some confessions, and the corresponding site in the lock body 1 is provided with the guide finger 11 that cooperates with each horizontal concrete chute 43.
