Description

Technical Field

[0001] This invention relates to a cabinet door switch, specifically a cabinet door push-button switch with a forced release function. Background Technology

[0002] Most households have furniture with hinged doors. Hinges typically connect the door to the cabinet body, opening and closing it via the hinges. Users usually open and close the doors using a protruding handle or similar component. Because of these protruding handles, users often bump into them, posing a safety hazard. Therefore, to address the shortcomings of existing technology, some cabinet doors have a push-button switch between the cabinet body and the door, allowing opening and closing by pressing. However, commercially available push-button switches are complex, often requiring repeated pressing to open and close. They also have a short lifespan; if the switch fails, the door cannot be opened or closed, causing inconvenience. Therefore, there is an urgent need for a push-button switch with a strong release function. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a cabinet door push-to-open switch with a simple structure, low manufacturing cost, easy and convenient cabinet door forced-open operation, and two opening methods: forced-open and push-to-open.

[0023] The invention will be further described in detail below with reference to the accompanying drawings. A cabinet door push-button switch with a strong release function includes a door latch 1 fixedly installed on the back of the door and a base 2 installed on the furniture. A lock cylinder is embedded in the base 2. The lock cylinder includes a movable groove 221 provided on the base 2. A drive seat 3 is slidably installed in the movable groove 221. The top of the drive seat 3 protrudes to form a guide post 31. Correspondingly, the base 2 is recessed to form a guide groove 211. The guide post 31 is locked in the guide groove 211. The drive seat 3 can move along the guide groove 211 in the movable groove 221.

[0024] The lock cylinder also includes a hook body 4. The drive base 3 is provided with an insertion hole 32 that is connected to one end of the hook body 4. The other end of the hook body 4 is bent and inserted into the locking groove 5 recessed in the base 2 and slides therein.

[0025] A spring 6 is also provided between the drive seat 3 and the base 2. The spring 6 always pushes the drive seat 3 to swing along the axis of the guide post 31, forcing the drive seat 3 to swing along the hanging groove 34 provided on its side wall. The drive seat 3 enters the drive groove 224 opened at the port of the base 2. The door latch 1 extends into the drive groove 224 and connects with the hanging groove 34 to close the door.

[0026] The inner end of the drive seat 3 is provided with a spring post 33 protruding, and one end of the spring 6 is wrapped in the spring post 33. The base 2 is provided with a spring groove 222, and the spring 6 is embedded in the spring groove 222. One end of the spring 6 presses against the spring groove 222, and the other end presses against the drive seat 3.

[0027] The hanging groove 34 is a recessed groove set inside the side wall of the drive seat 3.

[0028] The upper and lower ends of the drive seat 3 have protruding limit posts 35. Correspondingly, the base 2 is provided with a limit groove 223, and the limit post 35 is locked in the limit groove 223 and swings.

[0029] The hook body 4 has two ends bent to form connecting posts 41, and the ends of the connecting posts 41 are arranged in opposite directions; the insertion hole 32 is set on the circle of the guide post 31.

[0030] The locking groove 5 is configured to be conductive at both ends, with a first locking groove 51 and a second locking groove 52 extending from the inner end of the locking groove 5, and a release groove 53 extending from the outer end of the locking groove 5.

[0031] The base 2 includes an upper cover 21 and a lower cover 22, which are interlocked to house the lock cylinder.

[0032] The drive groove 224 is a concave V-shape and extends through the front end face of the base 2. The door latch 1 is inserted into the drive groove 224 from this port and connected to the hanging groove 34 of the drive seat 3.

[0033] The front end face of the drive seat 3 is provided with a reset guide slope that is inclined toward the hanging groove 34.

[0034] Working principle: In the push-button switch of the cabinet door, the lock cylinder includes a movable groove on the base. A drive seat is slidably installed in the movable groove and engages with the door latch. A guide post is formed by the protruding body on the top of the drive seat. Correspondingly, a guide groove is formed by the recess in the base. The guide post is engaged in the guide groove, allowing the drive seat to move along the guide groove within the movable groove.

[0035] A spring is installed between the drive seat and the base. The door latch passes through the drive groove at the port of the base and connects to the hanging groove on the side wall of the drive seat. Since the spring constantly generates a thrust to push the drive seat outward, the drive seat constantly swings along the axis of the guide post. As the door latch extends into the drive groove, it forces the drive seat to sway along the hanging groove, causing the hook connected to one side of the drive seat to slide in the locking groove of the base, thereby realizing the opening and closing of the door.

[0036] Within the locking groove, both ends are interconnected. The inner end of the locking groove extends into a first locking groove and a second locking groove, while the outer end extends into a release groove. When the door is not opened by a push-button mechanism but is forcibly opened, because the drive seat is tilted when the door is closed, as the user pulls the door outward, the hook disengages from the first locking groove along the locking groove and slides down the channel of the locking groove to the second locking groove. At this point, under the inertial thrust of the spring, the drive seat is tilted outward, the hook disengages from the second locking groove, and slides outward along the channel of the locking groove to the release groove, thus forcibly opening the door. This achieves forced door opening without the need for a push-button mechanism. While retaining the traditional push-button door opening and closing function, the addition of a forced door opening function enriches the door opening methods, thereby preventing damage to the door opener caused by forced opening.

[0037] The push-button switch for the cabinet door in this case features a simple internal structure and low manufacturing cost. It retains the original cabinet door opening and closing method while incorporating a forced-open mechanism. Operation is simple, quick, and easy. Even if the push-button switch fails, it can still force the cabinet door open, preventing inconvenience caused by switch damage. The diverse opening and closing methods extend the lifespan of the push-button switch, further reducing furniture usage costs, thus making it suitable for widespread adoption.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
