Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.

As shown in fig. 1-3, the utility model provides a cabinet lock body, include the first chamber that holds that is formed by lock shell 15, lock shell lid 17 lock, the first intracavity that holds is provided with trip subassembly, locking subassembly 3, motor module, emergent pole arm-tie 6, the motor module includes motor 13, decelerator, spring 11, micro-gap switch 4, control panel 5, emergent pole arm-tie 6 is in reciprocating motion is done under the effect of motor 13, decelerator, spring 11, emergent pole arm-tie 6 one end is connected locking subassembly 3, trip subassembly all with lock shell 15 rotates to be connected, locking subassembly 3 with trip subassembly meshing or counterbalance, micro-gap switch 4 with locking subassembly 3 touches pressure or separation.

Specifically, as further shown in fig. 2, the motor module forms the second and holds the chamber, 6 pot heads of emergency lever arm-tie are equipped with spring 11 and contradict in the second holds intracavity wall, emergency lever arm-tie 6 is in under the effect of motor 13, decelerator, spring 11 the second holds the intracavity and is reciprocating motion, 6 one end of emergency lever arm-tie is stretched out the second hold the chamber with locking component 3 connects, micro-gap switch 4 part stretches out the second hold the chamber with locking component 3 touches and presses or separates.

When the lock is unlocked, the motor 13 is started by receiving electricity to drive the speed reducer to rotate, the emergency rod pull plate 6 is in the speed reducer rotates and acts on the second accommodating cavity to move in a one-way mode, the spring 11 moves in a downward direction, namely a diagram, and the spring 11 is compressed to abut against the inner wall of the second accommodating cavity, the locking component 3 is under the pulling action of the emergency rod pull plate 6 and rotates clockwise in the first accommodating cavity until the locking component 3 rotates to the position where the locking component is not abutted any more, the locking component rotates after the state of abutting against the locking component to complete the unlocking, meanwhile, the locking component 3 is pressed against the microswitch 4, and the control panel 5 receives the state information of successful unlocking.

In the unlocking process, the motor 13 and the speed reducing device are combined, so that the power output effect of large torque and low rotating speed is realized, compared with the traditional mode that an electromagnet is electrified to provide unlocking power, the unlocking power is greatly enhanced, and even if the cabinet lock body is not installed in place or the cabinet door and the door frame are deformed, enough unlocking power can pull the locking assembly 3 downwards, so that the unlocking purpose can be achieved.

When the unlocking is finished, the control panel 5 cuts off the power supply of the motor 13, the speed reducing device stops rotating, the spring 11 releases elastic force, the emergency rod pull plate 6 moves upwards under the action of the spring 11 to push the stop component 3 to rotate anticlockwise, and the stop component 3 is separated from the microswitch 4.

When locking, 1 opening part of pothook subassembly receives the effect that comes from external force and presses, pothook subassembly 1 is in under the external force pressing effect first appearance intracavity rotation, until rotate to trip subassembly 1 with the separation after the locking subassembly 3 meshes completely, at this in-process, promote locking subassembly 3 rotates clockwise, locking subassembly 3 touches and presses micro-gap switch 4, control panel 5 receives the successful state information of closing the lock, and meanwhile, spring 11 is in locking subassembly 3, emergent pole arm-tie 6 are under the effect of conduction force in succession, compressed conflict in the second holds intracavity wall.

When the locking is finished, the pressing action of external force disappears, the spring 11 releases elastic force, the emergency rod pull plate 6 exerts upward force under the action of the spring 11 and is transmitted to the stop component 3, the stop component 3 rotates anticlockwise to be separated from the microswitch 4, and under the continuous action of the transmission force, the stop component 3 and the clamping hook component 1 are separated instantly after being completely meshed, namely, the stop component and the clamping hook component are quickly abutted.

Because the combination of the motor 13 and the speed reducer is adopted to replace the traditional electromagnet electrifying mode, the problems that the cabinet lock body has large working current, the control panel and the circuit are easily damaged, the electromagnet of the cabinet lock body is easily burnt out and the electrifying time of the cabinet lock body cannot be overlong in the traditional electromagnet electrifying mode are also avoided.

It should be noted that, according to different application requirements of different application scenarios for the cabinet lock body, when the sealing performance of the first accommodating cavity formed by buckling the lock shell 15 and the lock shell cover 17 can be sufficiently ensured, only the first accommodating cavity may be provided. Otherwise, a second accommodating cavity is formed by arranging the motor die, so that the sealing protection of the speed reducing device is improved.

Preferably, the lock housing 15 is provided with a plurality of connecting columns 151, the lock housing cover 17 is provided with a plurality of connecting holes 171, and the trip assembly and the stop assembly 3 are rotatably connected with the lock housing 15 in the first accommodating cavity through the connecting columns 151.

Through setting up the form of spliced pole 151, connecting hole 171 both can realize the effect of holding of first holding chamber can easily realize in step again trip subassembly, locking subassembly 3 with the rotation connection effect of lock shell 15.

Preferably, the trip subassembly includes trip piece 1, torsional spring 2 is located trip piece 1 below, overlaps jointly and locates one of them spliced pole 151, 2 one end of torsional spring collude in 2 lateral walls of trip piece, the other end with first chamber lateral wall counterbalance that holds, torsional spring 2 is in compression state when closing the lock, provides elasticity when unblanking.

Because the safe auto-lock characteristic of tool to lock self, through setting torsional spring 2 is in compression state when closing the lock, provides elasticity when unblanking, can make stop subassembly 3, trip subassembly are more smooth and easy in the state switching process of meshing with offsetting, specifically further as shown in fig. 2, 2 right side one end of torsional spring collude in 1 left side wall of trip piece, left side one end with first chamber left side wall of holding offsets, thereby makes trip piece 1 is only under the condition of 2 spring force effects of torsional spring, forms and only can follow clockwise pivoted drive power.

Preferably, the motor module further comprises a motor box 14 and a motor box cover 16, wherein the motor box 14 is provided with a limiting wedge block 141, a limiting hole 61 is formed in the middle of the emergency rod pulling plate 6, and the limiting hole 61 is matched with the limiting wedge block 141, so that the emergency rod pulling plate 6 can make linear motion in the second accommodating cavity.

Through the simple structure design that the motor box 14 and the motor box cover 16 are arranged, the limiting wedge block 141 is arranged on the motor box 14, and the limiting hole 61 is formed in the middle of the emergency rod pulling plate 6, the accommodating effect of the second accommodating cavity can be achieved, and the reciprocating linear motion of the emergency rod pulling plate 6 in the second accommodating cavity can be synchronously and easily achieved.
