Description

Technical Field

[0001] This invention relates to a cabinet door switch, specifically a cabinet door push-button switch with adjustable trigger stroke. 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 these shortcomings, some cabinet doors incorporate push-button switches between the cabinet body and the door, allowing opening and closing by pressing. However, commercially available push-button switches are complex in structure, often requiring repeated pressing to open and close, and have a relatively short lifespan. This type of push-button switch requires the user to press the gap between the cabinet door and the furniture all the way down to activate it and open or close. Since the installation gap between the cabinet and door varies for different types of cabinets, the push-button switch needs repeated adjustments during installation to achieve the correct trigger stroke. Alternatively, a separate pair of push-button switches can be used, resulting in high operating costs, relatively complex operation, and requiring considerable force and time from the user. Therefore, an adjustable trigger stroke push-button switch for cabinet doors is urgently needed. 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, adjustable trigger stroke, adaptability to the installation of various types of doors, and door opening methods including forced release and push-to-open.

[0022] The lock cylinder also includes a hook 4 and an adjusting seat 5 slidably connected thereto. The adjusting seat 5 is movably installed in the adjusting groove 23 formed by the recess of the base 2. The end face of the adjusting seat 5 is provided with a locking groove 6. One end of the hook 4 is inserted into the insertion hole of the drive seat 3, and the other end is bent and locked in the locking groove 6 for sliding. A locking mechanism is provided between the adjusting seat 5 and the base 2. The locking mechanism locks the relative position of the adjusting seat 5 in the adjusting groove 23, thereby realizing the fine adjustment of the trigger stroke between the door 1 and the cabinet 10.

[0023] A spring 321 is also provided between the drive seat 3 and the base 2. The spring 321 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 33 provided on its side wall. The drive seat 3 enters the drive groove 25 opened at the port of the base 2. The door latch 11 extends into the drive groove 25 and connects with the hanging groove 33 to realize the closing of the door 1.

[0024] The locking mechanism includes a positioning platform 51 protruding from the outer side of the adjusting seat 5. Correspondingly, a plurality of adjusting teeth 231 are recessed in the side wall of the adjusting groove 23. The positioning platform 51 is locked in the adjusting teeth 231 to lock the position of the adjusting seat 5.

[0025] The outer side of the adjustment seat 5 protrudes to form a limiting platform 52, which is locked in the positioning groove 232 that is connected to the adjustment groove 23.

[0026] The positioning platform 51 and the adjusting tooth 231 are similar in shape and are set in a pointed shape.

[0027] The locking mechanism includes an adjusting screw 7, which is screwed into a threaded hole 27 at the port of the base 2. The inner end of the adjusting screw 7 protrudes from the body and has a hanging plate 71, which is fastened to the connecting groove 53 of the adjusting seat 5. By rotating the adjusting screw 7, the displacement of the adjusting seat 5 in the adjusting groove 23 is adjusted, and the position of the adjusting seat 5 is locked.

[0028] The inner end of the drive seat 3 is provided with a spring post 32 protruding, and one end of the spring 321 is wrapped in the spring post 32; the base 2 is provided with a spring groove 24 recessed inward, and the spring 321 is embedded in the spring groove 24, with one end of the spring 321 pressing against the spring groove 24 and the other end pressing against the drive seat 3.

[0029] The upper and lower ends of the drive seat 3 have protruding limit posts 34. Correspondingly, the base 2 is provided with a limit groove 26, and the limit post 34 is locked in the limit groove 26 and swings.

[0030] The locking groove 6 is configured to be conductive at both ends, with a first locking groove 61 and a second locking groove 62 extending from the inner end of the locking groove 6, and a release groove 63 extending from the outer end of the locking groove 6.

[0031] The drive groove 25 is a concave V-shape and extends through the front end face of the base 2. The door latch 11 is inserted into the drive groove 25 through the opening and connected to the hanging groove 33 of the drive seat 3. The front end face of the drive seat 3 is provided with a reset guide slope that is inclined toward the hanging groove 33.

[0032] Working principle: In the push-button switch of the cabinet door, the lock cylinder includes a movable groove on the base, and a drive seat is slidably installed in the movable groove to engage with the door latch. A guide post is formed by the protrusion of the drive seat on its top body, and correspondingly, a guide groove is formed by the indentation on 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.

[0033] The lock cylinder structure also includes a hook and an adjusting seat that slides through it. A locking groove is recessed on the end face of the adjusting seat. One end of the hook is inserted into the insertion hole of the drive seat, while the other end is bent and secured in the locking groove. A locking mechanism is provided between the adjusting seat and the base. This mechanism locks the relative position of the adjusting seat within the adjusting groove, thereby adjusting the trigger stroke between the door and the cabinet. After the trigger stroke is adjusted, the door latch passes through the drive groove at the base port and connects to the mounting groove of the drive seat. Because the spring constantly generates thrust, pushing the drive seat outwards, 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 deflect along the mounting groove, thus closing the door. Example

[0034] like Figure 2-4 As shown: The locking mechanism in this case includes a positioning platform protruding from the outside of the adjusting seat. Corresponding to the positioning platform, several adjusting teeth are recessed in the side wall of the adjusting groove. Based on the time gap between the door and the cabinet, the positioning platform selects the appropriate adjusting teeth for engagement, thereby locking the adjusting seat in the adjusting groove. To prevent excessive adjustment of the adjusting seat, a limiting platform is formed on the protruding body of the adjusting seat. This limiting platform engages within the positioning groove, which communicates with the adjusting groove, restricting the adjusting seat to slide only within this positioning groove and limiting its travel distance. Example

[0035] like Figure 5-7 As shown: The locking mechanism in this case includes an adjusting screw. The inner end of the adjusting screw is provided with a connecting groove for a hanging plate and an adjusting seat, which connects the locking mechanism to the adjusting seat. To mate with the adjusting screw, a threaded hole is provided at the end of the base. The adjusting screw is screwed into this threaded hole. Rotating the adjusting screw converts its rotational motion into linear motion of the adjusting seat, adjusting the adjusting seat's movement within the adjusting groove, thereby locking the adjusting seat in its position within the adjusting groove.

[0036] In the two embodiments described above, the adjustment seat is configured to slide and is equipped with a locking mechanism to lock the specific position of the adjustment seat and adjust the trigger stroke of the push-button switch. Users can adjust the trigger stroke according to the specific installation gap between the cabinet door and the furniture so that the push-button switch reaches the optimal working state. The structure is simple, the operation is convenient and quick, and it is suitable for the installation of various types of cabinet doors and furniture, making it highly practical.

[0037] Furthermore, within the locking groove of the drive seat, its two ends are interconnected. A first locking groove and a second locking groove extend from the inner end of the locking groove, while a release groove extends from the outer end. When the door is not opened by a push-button action but is forcibly pulled outwards, because the drive seat is tilted when the door is closed, as the user pulls the door outwards, the hook disengages from the first locking groove along the locking groove and slides down the groove to the second locking groove. At this point, under the inertial thrust of the spring, the drive seat is tilted outwards, the hook disengages from the second locking groove, and slides down the groove to the release groove, thus forcibly opening the door. This achieves forced door release without the need for a push-button action. While retaining the traditional push-button opening and closing function, the addition of a forced door release function enriches the diversity of door opening methods. Even if the push-button switch fails, the cabinet door can still be forcibly opened, preventing inconvenience in accessing items inside the cabinet due to switch damage. The versatility of the cabinet door opening and closing methods extends the lifespan of the push-button switch, further reducing furniture usage costs, thus making it suitable for widespread adoption.

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.
