Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0039] Such as figure 1 with figure 2 As shown, a single tongue lock body includes a lock case 4 formed by a combination of a panel assembly 1, a bottom plate assembly 2 and a cover plate assembly 3. A latch bolt assembly 5, a slider 6 moving in a straight line, and A linkage assembly 7 that transmits kinetic energy between the slider 6 and the latch tongue assembly 5 is connected. Inside the lock case 4 there are also a rotary drive assembly 8 and a safety assembly 9 that drive the slider 6 to move.

[0040] Such as figure 1 with figure 2 As shown, the latch bolt assembly 5 includes: a lock bolt 10 and an accommodating box 11 with a cavity formed therein for accommodating the lock bolt 10. The accommodating box 11 is fixedly connected to the panel assembly 1 on one side located in the lock case 4 and faces the panel. One side of the component 1 is con...

Abstract

The invention discloses a single-bolt lock which comprises a lock shell. The lock shell comprises a face plate component, a bottom plate component and a cover plate component. A latch bolt component is arranged in the lock shell and comprises a lock bolt and an elastic part for driving the lock bolt to pop out of the lock shell. A slider, a safety component and an unlocking component are arrangedin the lock shell. The slider only moves horizontally along a single linear direction to form locked and unlocked states in the linear movement direction. The safety component is capable of peripherally rotating to control the slider to move linearly for switching between the locked and unlocked states. The unlocking component comprises a rotating driving component and a linkage component, the rotating driving component drives the slider in the unlocked state to move opposite to a locked-state position, and the linkage component is driven by the slider in continuous displacement to drive the lock bolt to retract into the lock shell. The safety component drives the slider to switch between the locked state and the unlocked state; in the unlocked state, the unlocking component drives the slider to continue moving into the lock shell under the driving action of the linkage component.

Description

technical field [0001] The invention relates to a lock body, in particular to a single tongue lock body. Background technique [0002] The invention patent with application publication number CN102022040A discloses a double tongue lock body for a house door. The invention reduces the overall structural size by nesting the oblique lock bolt and the square lock bolt. [0003] Although the structural size is all reduced, this invention has the following problems: since the oblique bolt and the square bolt are required to play the switch and safety effects respectively, it is necessary to set parts that are respectively linked with the oblique bolt and the square bolt. The structure is still more complex. [0004] The patent of invention whose authorized notification number is CN104314371B discloses a single tongue lock body structure. In this solution, the internal structure of the lock body is relatively simple, but the solution has the following problems: the lock body doe...
