Detailed Description

In order to better understand the invention for those skilled in the art and to define the claimed scope more clearly, the invention will be described in detail below with respect to certain specific embodiments of the invention. It should be noted that the following description is only a few examples of the present invention, and the specific and direct descriptions of the related structures are only for the convenience of understanding the present invention, and the specific features do not naturally and directly limit the scope of the present invention. Conventional alternatives and substitutions made by those skilled in the art in light of the teachings of the present disclosure should be considered as within the scope of the present disclosure.

A cabinet lock is mainly used for locking parts such as cabinet doors, drawers of cabinets or doors or drawers of other furniture and the like so as to avoid possible safety problems or messy articles caused by unauthorized operation of children or infants.

The cabinet lock comprises a lock body, wherein a base surface 11 and an end surface 12 intersected with the base surface 11 are formed on the lock body, and the base surface 11 and the end surface 12 can be planes, curved surfaces, spherical surfaces and the like; from a practical point of view, the base surfaces 11 and 12 should be mainly plane.

As shown in the figure, three directions perpendicular to each other are defined as an X-axis direction, a Y-axis direction, and a Z-axis direction, and the base surface 11 is mainly disposed along an XY plane. The base surface 11 is used for fixing the cabinet lock on the cabinet by contacting the cabinet lock with the cabinet, and the fixing method may be adhesion, screw fixation, etc.

The cabinet lock further comprises an actuating mechanism 200, wherein the actuating mechanism 200 comprises an actuating member 210, a limiting member 220 and an unlocking member 230; the actuator 210 has a bolt 201, and the actuator 210 is movably engaged to the lock body to allow the bolt 201 to extend or retract relative to the end face 12. When the lock tongue 201 extends out of the end face 12, the cabinet lock is matched with a lock seat with a lock hole to realize a locking function; when the latch bolt 201 is separated from the locking hole of the lock base and retracted into the end surface 12, the cabinet lock is separated from the lock base to be unlocked. That is, the actuator 210 is movably disposed to be able to move left and right within a certain range along the X-axis direction, and the latch bolt 201 retracts when it moves in the positive direction along the X-axis direction, and the latch bolt 201 extends when it moves in the negative direction along the X-axis direction.

The lock body is also internally provided with a guide member 130 arranged along the Z-axis direction, and the limiting member 220 is matched with the guide member 130, so that the limiting member 220 can only be movably arranged along the Z-axis direction in the guide member 130 in a vertical displacement manner and respectively forms a first matching position and a second matching position; when the limiting member 220 is located at the first matching position, the limiting member 220 abuts against the actuating member 210 to prohibit the actuating member 210 from moving, so as to lock the moving movement of the lock tongue 201; when the position-limiting member 220 is in the second engaging position, it does not contact with the actuating member 210, and the actuating member 210 can move freely to drive the latch bolt 201 to move correspondingly, thereby driving the latch bolt 201 to retract.

The lock body comprises a base 110, and an action mechanism 200 is matched on the base 110; the base surface 11 and the end surface 12 are both disposed on the base 110, and the end surface 12 is further provided with a latch hole for the latch 201 to extend out. The base 110 is further provided with a limiting cavity 130, and the limiting member 220 is fitted in the limiting cavity 130, so that the limiting member 220 is disposed and fitted in the limiting cavity 130 in a manner of being capable of moving up and down only along the Z-axis direction. For this purpose, the limiting cavity 130 includes a first limiting block 131 and a second limiting block 132 disposed along the Z-axis direction, and the limiting member 220 is disposed between the first limiting block 131 and the second limiting block 132, so that the limiting member 220 can be movably disposed only along the Z-axis direction.

In order to drive the limiting member 220 to move up and down in the Z-axis direction, a first guiding portion 221 is disposed on the limiting member 220; meanwhile, a second guide portion 232 is disposed on the unlocking member 230; at least one of the first guiding portion 221 and the second guiding portion 232 is an inclined surface or a curved surface, so that the limiting member 220 can move up and down along the Z axis under the driving of the unlocking member 230 by the displacement of the unlocking member 230 along the X axis direction in cooperation with the limiting effect of the two guiding portions and the limiting member on the limiting member. In practice, one of the first guiding portion 221 and the second guiding portion 232 is an inclined surface or a curved surface, and the other one is a common protrusion, and the limiting member 220 is driven by the protrusion matching with the inclined surface or the curved surface; alternatively, the first guiding portion 221 and the second guiding portion 232 may be inclined surfaces or curved surfaces that are matched with each other, so as to drive the limiting member 220 in a matching manner.

For the sake of simplifying the structure, the unlocking member 230 includes a limiting guide 231, and the second guide 232 is disposed on the limiting guide 231, for example, at the front end thereof; the two limiting guide parts 231 are arranged at intervals, an unlocking piece cavity 233 is formed between the two limiting guide parts at intervals, and the width of the unlocking piece cavity 233 is larger than or equal to that of the second limiting piece 132. When the limiting member 220 is fitted in the limiting cavity 130, the displacement of the limiting member 220 in the X-axis direction is limited by the first limiting block 131 and the second limiting block 132, and the displacement of the limiting member 220 in the Y-axis direction is limited by the two limiting guide portions 231, so that the limiting member 220 can be movably disposed only in the Z-axis direction.

In addition, in order to ensure the limiting effect, a spring is further disposed between the limiting member 220 and the limiting cavity 130, so that the limiting member 220 is located at the first matching position to limit the actuating member 210 when no external force acts on the limiting member. In order to fix the spring, a spring fixing seat may be disposed in the limiting cavity 130.

In some embodiments, the position-limiting member 220 includes a first guiding portion 221 and a position-limiting portion 222, where the first guiding portion 221 has two portions and is disposed on two sides of the position-limiting portion 222 respectively; the position-limiting portion 222 is higher than the first guiding portion 221 to abut against the actuator 210 to limit the actuator. The limiting portion 222 is hollow for the spring to fit therein, and a spring fixing seat (not shown) may also be provided therein, so that two ends of the spring fold disposed between the limiting member 220 and the limiting cavity 130 are respectively fixed by the two spring fixing seats, which has a positive effect on the assembly process of the product. In addition, the limiting portion 222 is further provided with an elastic limiting member 223 on a surface contacting with the first limiting member 131 and the second limiting member 132, and the first limiting member 131 and the second limiting member 132 are correspondingly provided with limiting holes arranged along the Z-axis direction; when the limiting member 220 is fitted in the limiting cavity 130, the elastic limiting member 223 is fitted in the limiting hole, so that the first fitting position of the limiting member 220 is limited, and the first fitting position is only moved up and down along the Z axis within the set interval range. Of course, it is also possible to use the first guiding portion 221 to contact the actuating member 210 without the position-limiting portion 222.

In other embodiments, the actuator 210 includes a latch portion 211 and an actuating portion 212, which are separate components and cooperate to form the actuator 210.

The front end of the bolt 211 is formed as a bolt 201, and the rear end is formed as a bolt connecting part; the bolt connecting part is long, and is provided with a rear stop block 213, a front stop block 215 and a connecting groove 214 positioned between the two; a rear stopper 213, a front stopper 215, and a connection groove 214 are symmetrically provided at both sides of the latch bolt connection part.

The actuating portion 220 includes an actuating body 218, and a cavity is formed in the actuating body 218; the front end of the actuating body 218 is provided with an actuating connection, which includes two connecting blocks 216 and a groove 217 between the two connecting blocks 216. When the latch 211 and the actuating part 212 are matched to form the actuating element 210, the two connecting blocks 216 are respectively matched in the connecting grooves 214 on the two sides of the latch connecting part, and at the moment, the main part of the latch connecting part is matched in the groove 217; the rear stopper 213 and the front stopper 215 of the latch portion 211 define a fitting relationship between the actuating connecting portion and the latch connecting portion, and the connecting piece 216 of the actuating portion 212 is always positioned between the rear stopper 213 and the front stopper 215.

A limiting block 219 capable of abutting against the limiting member 220 is formed at the rear end of the actuating portion 212, and when the limiting member 220 is located at the first matching position, the limiting block 219 abuts against the limiting member 220, so that the actuating portion 212 is prohibited from moving forward along the X axis; when the position-limiting element 220 is switched from the first matching position to the second matching position, the position-limiting element 220 moves downward along the negative direction of the Z axis, and the position-limiting element 220 enters the cavity of the actuating body 218, so that the position-limiting element 219 is separated from the position-limiting element 220, and at this time, the position-limiting element 220 does not have any influence on the actuating portion 212 because it is located in the cavity, so that the actuating portion 212 can move along the positive direction of the X axis, so that the actuating portion 212 moves rightward, and the connecting block 216 is matched with the rear stopper 213 to drive the lock tongue portion 211 to synchronously move rightward, so that the lock tongue 201 retracts.

The body 218 extends laterally and is formed as a key 202, the key 202 being exposed outside the lock body for easy operation.

Preferably, the actuating unit 210 further includes a return spring disposed between the latch 211 and the base 110, so that the latch 211 tends to extend and is automatically returned after the external force is removed. The connecting block 216 and the rear stop block 213 can be matched to enable the two to synchronously displace along the X-axis direction, including retracting and extending processes; the connecting block 216 cooperates with the front stop 215 to prevent the latch 211 from being excessively contracted and completely entering the inner cavity of the actuating portion 212 to disable the function of the latch.

In other embodiments, the lock body further comprises an upper shell 120, which is fixed to the base 110 by fastening, screwing, bonding, etc. to form a whole; after the upper housing 120 and the base 110 are engaged with each other, a chamber is formed therebetween, and at least a portion of the actuating mechanism 200 is disposed in the chamber.

Although, in the above embodiments, the limiting member 220 is movably disposed only in the Z-axis direction so as to be vertically displaceable, it is not necessarily so. In fact, under the condition that the structures of the limiting member 220 and the limiting cavity 130 are substantially unchanged, it is also feasible to configure the unlocking member 230 to be disposed along the Z axis in a manner of being displaced up and down, so as to drive the limiting member 220 to be displaced up and down along the Z axis to move from the first matching position to the second matching position. Alternatively, the unlocking member 230 is coupled in a rod shape, and the middle thereof is hingedly coupled to the locking body, so that the front ends thereof are oppositely moved by corresponding control of the ends thereof, thereby driving the movement of the limiting member 220 up and down. Therefore, the unlocking member 230 may have various alternative embodiments on the premise that the limiting member 220 is movably disposed along the Z-axis in a manner of moving up and down, and other available alternatives in the prior art are also included.

In addition, the limiting member 220 may not be movably disposed along the Z axis in a vertically displaceable manner, but may be movably disposed along the Y axis. The implementation process is that under the initial condition, the limiting member 220 cannot move along the X axis and the Z axis, and the limiting member 220 abuts against the end of the actuating member 210 to prohibit the lock tongue 201 from retracting; the unlocking member 230 is operated to displace the position-limiting member 220 a certain distance in the Y-axis direction, and the actuator 210 has a gap therein, so that the actuator 210 can be displaced in the Y-axis direction to retract the latch bolt 201. In this case, the unlocking member 230 may drive the limiting member 220 in the same manner as the other embodiments, and the two are only different in direction.

When the cabinet lock is matched with cabinets in different forms, the cabinet lock can be matched with lock seats in different forms. For example, as shown in fig. 15, when the cabinet door 102 (or drawer front panel) of the cabinet is flush with the cabinet top 101 of the cabinet, an overall thinner and long lock seat may be used for cooperation; the lock seat is composed of a fixing portion 311 and a lock hole portion 312, the bottom surface of the fixing portion 311 is fixed to the cabinet top 101, for example, by 3M adhesion, and the lock hole engaged with the lock tongue 201 is disposed below the lock hole portion 312 and located outside the surface of the cabinet door for the cabinet lock to engage with to form a locking relationship. Alternatively, as shown in fig. 16, when the cabinet door 102 (or the drawer front panel) of the cabinet is extended and covered by the cabinet top 101 of the cabinet, a lock seat consisting of a thin fixing portion 311 and a relatively thicker lock hole portion 312 may be adopted, the fixing portion 311 extends into a gap between the cabinet top and the cabinet door and the top portion thereof is fixed below the extended portion of the cabinet top, for example, 3M glue, and the lock hole is disposed below the lock hole portion 312 and located at the outer side of the surface of the cabinet door for the cabinet lock to cooperate with to form a locking relationship.

Although the two lock holders are described in connection with embodiments in which the top and the door have different mating relationships, they are equally applicable to cabinets having similar relationships between the sides and the bottom.

It should be noted that, although the product name of the present invention is a cabinet lock, the cabinet therein does not refer to the cabinet referred to by the platform for storing kitchen utensils and cooking operations, which is composed of the cabinet body, the door plate, the hardware, the table top, etc. in the kitchen in the traditional sense, but refers to various cabinets and cabinets in daily life, and is applicable to furniture or small appliances having openable parts such as doors or drawers in home life.
