Detailed Description
As shown in fig. 1-5, the automatic steering push-pull cabinet miniature lock comprises a bolt 1 and a motor which linearly reciprocate, and further comprises a reversing plate 2, a locking plate 3 and a cam 4, wherein the cam 4 and the motor are assembled in a linkage manner, the locking plate 3 is provided with a central part 5, a driving part 6 and a driven part 7, and the driving part 6 and the driven part 7 respectively rotate in the same plane by taking the central part 5 as a circle center. The driving portion 6 and the driven portion 7 have the same rotation plane, and in this embodiment, there is a limiting portion 8 located on the same plane, and the three portions have different functions. The cam 4 and the motor are linked to rotate, in the embodiment, the driven part 7 of the locking plate 3 is not limited too much, and the driven part 7 and the cam 4 can be limited in blocking and connecting mode or in clamping mode, and the method is particularly determined by actual production and use.
The direction changing plate 2 has a rotating portion 9, an abutting portion 10, and an interlocking portion 11, and the abutting portion 10 and the interlocking portion 11 each rotate in parallel planes about the rotating portion 9. The contact portion 10 and the interlocking portion 11 are not on the same plane, but are on parallel planes because the rotation centers are the same. In this embodiment, the direction changing plate 2 is a half-fan structure, and the abutting portion 10 is on the circumferential side wall of the direction changing plate 2, so that the abutting linkage with the abutting block 13 is conveniently realized.
The locking plate 3 is perpendicular with the axis of rotation of the reversing plate 2 mutually, be equipped with on the initiative portion 6 and supply 11 sliding fit's of linkage movable surface 12, be equipped with butt piece 13 on the spring bolt 1, be equipped with the elasticity piece that resets on the locking plate 3, the state of unblanking and the state of locking have between spring bolt 1, reversing plate 2, locking plate 3 and the cam 4. It should be noted that the movable surface 12 means that when the linkage part 11 pushes the active part 6 in the direction of the reverse elastic restoring force or the active part 6 pushes the linkage part 11 in the direction of the normal elastic restoring force, the linkage part 11 always moves relatively along the movable surface 12.
In the unlocking state, the bolt 1 drives the abutting block 13 to abut against and link with the abutting part 10 of the reversing plate 2, the linkage part 11 pushes the driving part 6 of the locking plate 3 to rotate along the surface of the movable surface 12, and the driven part 7 of the locking plate 3 is separated from the cam 4 and the rotating path thereof; when the lock is locked, the locking plate 3 drives the driving part 6 and the linkage part 11 to rotate through the elastic reset piece, the driven part 7 of the locking plate 3 is in limit fit with the cam 4 to limit the operation of the motor, and the abutting part 10 of the reversing plate 2 pushes the abutting block 13 and the bolt 1 to be away from the locking plate 3. In short, the lock tongue 1 retracts into the lock body, the lock tongue 1 drives the abutting block 13 to push the reversing plate 2 to rotate, the locking plate 3 is further driven to rotate, the locking plate 3 is separated from the cam 4, and the operation of a motor cannot be limited; on the contrary, the locking plate 3 is influenced by elasticity and acts reversely, the locking plate 3 drives the reversing plate 2 to rotate reversely, and meanwhile the bolt 1 extends out of the lock body. The key point is that the abutting block 13 of the bolt 1 and the linkage part 11 of the reversing plate 2 directly influence locking through two transmission structures. It should be pointed out that drives spring bolt 1 through opening and close the case cabinet door and stretch out and draw back, locks and unblanks the motor operation in step to this realizes predetermineeing the target.
The elastic reset piece is a torsion spring arranged on the central part 5, so that the rotation reset of the elastic reset piece is realized, and the assembly is convenient. The locking device also comprises a spring for pushing the bolt 1 away from the locking plate 3, so that the bolt 1 is kept in an extended state as far as possible, namely a locking state. The reversing plate 2 is further provided with a limiting plate 14 assembled coaxially, the locking plate 3 is further provided with a limiting part 8 rotating on the same plane, the limiting part 8 and the limiting plate 14 rotate to be blocked and limited, excessive rotation is avoided, or the use loss of important parts is reduced, so that deformation and deviation are avoided. The movable surface 12 is a cambered surface with an S-shaped path, which is beneficial to the reciprocating movement of the linkage part 11 on the plane.
In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are directions or positional relationships indicated based on the drawings, and are only for convenience of description and simplification of the description, but not for indicating or implying that the device or element indicated must have a specific direction, be constructed and operated in a specific direction, and therefore, cannot be understood as a limitation of the present invention, and the fundamental principles, main features and advantages of the present invention are shown and described above, and should be understood by those skilled in the art.
