Abstract

An inoperative swing handle structure for a safe comprises a door (1), a slide plate (2), a handle poke sheet (3), a handle seat (5), a swing handle (6), a coupling sheet (7) and a handle clamping plate (9). A slot (21) is provided in the slide plate (2). A driving pin (4) fixed on upper end of the handle poke sheet (3) is inserted the slot (21) and drives the slide plate (2) to slide relative to the door (1). The handle seat (5) is fixed on the door (1) and is provided with an inner concave part (51) opening toward the outside. One side of the swing handle (6) is pivoted at one side of the inner concave part (51), so that the swing handle (6) can swing perpendicular to the door (1). One end of the coupling sheet (7) is fixed to the swing handle (6), and the other end is fixed with a swing shaft (8). The lower end of the handle poke sheet (3) is provided with a connection edge (31) folded downwards and movably sleeved on the swing shaft (8) and moving along axial direction of the swing shaft (8). The handle clamping plate (9) is provided at the rear of the door (1) and can longitudinally slide relative to the door (1). The lower end of the handle clamping plate (9) is provided with a connection wall (91) folded upwards. A bar shape guiding hole (92) is transversely provided in the connection wall (91) and can be movably passed through by the swing shaft (8). The handle poke sheet (3) is longitudinally limited on the connection wall (91) and can transversely slide relative to the connection wall (91). The slot (21) is L shape. When the door is closed, the driving pin (4) will be provided in a transverse slot (212) of the slot and the handle poke sheet (3) can only transversely move relative to the slide plate (2).Even if the swing handle (6) is pulled, the slide plate (2) can not be driven to transversely slide so as to open the door.

Abstract

A panel of an electronic combination lock includes a base plate (1) provided with a keyboard part (11) for inputting codes and a rotatable cover board (2) covering the keyboard part (11) for inputting codes. One side of the rotatable cover board (2) is rotatablely connected to one side of the base plate (1) and a rotation limiting structure is provided between the rotatable cover board (2) and the base plate (1). The rotatable cover board (2) is limited to cover the keyboard part (11) for inputting codes by the rotation limiting structure.

Abstract

A cylinder lock with double opening angles includes a lock shell (1), a lock core (2), key holes (4, 6) and ball components (7, 8). The key holes (4, 6) are respectively a main key hole (4) and a secondary key hole (6). The ball components (7, 8) are respectively a first ball component (7) and a second ball component (8). The outer periphery surface of the lock core (2) is provided with a step part (21) which is inward depressed towards the center of a circle and extends along the axial direction of the lock core (2). When a main key (3) has been inserted into the main key hole (4), the rotation of the main key (3) can drive the lock core (2) to rotate to the first opening angle until balls (81) of the second ball component (8) are contacted with the step part (21), and when a secondary key (5) is inserted into the secondary key hole (6), the secondary key (5) will drive balls (81) of the second ball component (8) to release the contact between balls (81) and the step part (21), so that the lock core (2) is driven by the simultaneous rotation of the main key (3) and the secondary key (5) to rotate to the second opening angle. A safety lock structure provided with the cylinder lock is also provided.

Abstract

A security door with an electric emergency function comprises a door plate (1), an electrically coded lock (2), a magnet valve (3) with a valve core (31) and a cylinder lock (4). The security door also comprises a main pushing blade (5) and an emergency pushing blade (6), both of which are located on the back side of the door plate. The main pushing blade (5) whose end surface is provided with a pushing column (51) protruding outwards is fixedly connected with the inner end of the lock core (42) of the cylinder lock and can rotate together with the lock core. The emergency pushing blade (6) with an arc-shaped guide groove (61) in which the pushing column can be inserted and slide is axially limited on the inner end of the lock core of the cylinder lock and can rotate with respect to the lock core. After the rotation of the main pushing blade over a certain angle, the emergency pushing blade is rotated by the engagement of the pushing column and the arc-shaped guide groove, where the rotation of emergency pushing blade can push the valve core of the magnet valve. The cylinder lock of the security door has functions of a main lock and an emergency lock, hence the structure of the door is simple and reasonable.
