Abstract
Description
Technical Field
[0001] This utility model relates to the field of smart furniture technology, specifically a drawer trigger with adjustable trigger gap. Background Technology
[0002] Handleless drawers typically use a push-to-open mechanism. This mechanism usually involves a trigger device at the end of the drawer slide. After the drawer panel is pressed to a certain distance, the trigger device releases its lock, and a spring force pushes the drawer open a short distance, allowing the user to pull it out further. Traditional trigger devices usually have a fixed trigger distance, meaning the drawer panel needs to be pressed to a preset distance to open. If the gap between the drawer and the cabinet is too large after installation, the required trigger distance may not be reached, preventing the drawer from opening properly. Conversely, if the gap is too small, while the user can easily trigger the drawer, the small gap affects the drawer's appearance and may even cause the drawer panel to rub against the cabinet. To solve this problem, installers often need to repeatedly adjust the drawer's position on the slide to find a midpoint that ensures both proper triggering and a suitable gap between the drawer panel and the drawer. This adjustment process is time-consuming and labor-intensive, reducing installation efficiency and increasing labor costs. Utility Model Content

[0024] The present invention will be further described in detail below with reference to the accompanying drawings. A drawer trigger with adjustable trigger gap includes a fixed base 1 mounted on a guide rail 4, a guide seat 2 provided on the fixed base 1, and a stop block 3 slidably mounted in the guide seat 2.
[0025] An adjustment knob 5 is rotatably installed inside the fixed base 1. The adjustment knob 5 is connected to the impact block 3. Rotating the adjustment knob 5 drives the impact block 3 to move back and forth inside the guide seat 2.
[0026] like Figure 1-2 As shown: A fixed base is mounted on the guide rail, and a stop block is installed within a guide seat set in the fixed base, restricting the stop block's back-and-forth sliding within this guide seat. When the user rotates the adjustment knob, the rotational motion of the knob is converted into the back-and-forth linear motion of the stop block, thereby adjusting the relative position of the stop block within the guide seat. The change in the back-and-forth position of the stop block directly affects the distance the drawer needs to be pushed in to contact the stop block and further trigger the drawer to open, thus achieving the purpose of adjustable trigger gap and enabling the drawer trigger to have the ability to adjust the trigger position. Compared with existing triggers with fixed trigger positions or fixed trigger strokes, the user can change the required pressing stroke by rotating the knob, thereby solving the problem of installation difficulties caused by fixed trigger gaps in existing technologies.
[0027] The impact block 3 has a recessed groove 31, and the adjustment knob 5 is rotatably installed in the groove 31.
[0028] like Figure 4 As shown: The impact block is provided with a recessed rotating groove, and the adjustment knob is rotatably installed in the rotating groove. The rotational movement of the adjustment knob is connected with the movement of the impact block. The structure is compact, minimizes the possibility of interference from external parts, and the connection is stable and reliable.
[0029] The rotating groove 31 has several adjusting protrusions 32. Correspondingly, the bottom of the adjusting knob 5 is recessed to form an adjusting groove 51. The adjusting protrusions 32 are engaged in the adjusting groove 51. When the adjusting knob 5 is rotated, the adjusting protrusions 32 slide along the adjusting groove 51 to adjust the relative position between the impact block 3 and the guide seat 2.
[0030] like Figure 4-5As shown: An adjusting boss is raised within the rotating groove. A corresponding adjusting knob has an adjusting groove recessed at its bottom, and the adjusting boss engages within this groove. When the adjusting knob rotates, it moves within the rotating groove, causing the adjusting groove and the adjusting boss to slide relative to each other. As the adjusting boss slides along the adjusting groove, it forces the assembly with the rotating groove to move back and forth within the guide seat.
[0031] By rotating the adjustment knob, the user can control the position of the boss in the groove, thereby precisely adjusting the front-to-back relative position of the impact block with respect to the guide seat, and thus changing the trigger gap. The structure is simple, reliable and easy to manufacture. It can effectively convert the rotation operation of the adjustment knob into the linear displacement of the impact block, ensuring the smoothness of the adjustment process and the stability of the position after adjustment.
[0032] The adjusting groove 51 is a spiral groove.
[0033] like Figure 5 As shown: The adjustment groove is designed as a spiral groove. When the adjustment knob is rotated, the spiral groove engages with the adjustment boss of the impact block, confining the adjustment boss within the spiral groove. As the adjustment knob rotates, the adjustment boss passively slides along the trajectory of the spiral groove, thereby driving the impact block to move. The spiral groove design effectively converts rotational motion into linear motion, resulting in a simple structure, low manufacturing difficulty, and a stable, smooth, and continuous adjustment stroke. Users can precisely control the rotation angle of the adjustment knob and the forward and backward movement distance of the impact block by selecting appropriate spiral groove parameters, achieving precise adjustment of the trigger gap.
[0034] The adjustment bosses 32 are arranged in several horizontally.
[0035] like Figure 4 As shown, the adjusting bosses are arranged in a horizontal distribution, rather than a single one as in conventional designs. By increasing the contact area between the adjusting bosses and the adjusting grooves, the torque of the adjusting knob can be transmitted and converted more stably, reducing wear or jamming that may occur with single-point contact. Multiple points of support or contact help improve the smoothness and positioning accuracy of the impact block's forward and backward movement, reducing vibration or skewness during adjustment. The horizontal distribution design helps balance the radial force generated when the adjusting knob rotates, allowing the impact block to slide more smoothly back and forth within the guide seat, avoiding wobbling, improving the accuracy requirements of the trigger gap, and enhancing the stability and reliability of the adjustment process. At the same time, multiple adjusting bosses can distribute the load more evenly, reducing local stress and extending the service life of the mechanism.
[0036] The adjustment knob 5 is provided with a protruding rotating groove 31; the outer cylindrical surface of the adjustment knob 5 is provided with a number of anti-slip teeth 52; the top of the adjustment knob 5 is raised to form a rotating shaft 53, the guide seat 2 is provided with a rotating hole 21, the rotating shaft 53 is inserted and connected in the rotating hole 21, and the adjustment knob 5 rotates along the rotating hole 21.
[0037] like Figure 4-5 As shown: The adjustment knob features a protruding rotating groove, allowing users to rotate it via this protrusion. This convenient touch control eliminates the need for manual exploration, making adjustments more intuitive and efficient. Simultaneously, the anti-slip teeth on the outer cylindrical surface of the adjustment knob increase friction during rotation, resulting in a more stable and precise adjustment process, preventing slippage. This is particularly suitable for situations where the user's hands are wet or fine adjustments are required.
[0038] Furthermore, the rotating shaft at the top of the adjustment knob is inserted into the rotating hole of the guide seat, restricting the adjustment knob to rotate only along the rotating hole and locking the position of the adjustment knob in the guide seat. Therefore, the adjustment knob is stationary relative to the guide seat during rotation, but slides relative to the impact block, ensuring that the rotational motion of the adjustment knob is converted into the linear displacement of the impact block.
[0039] The impact block 3 extends upward on one side to form a buckle 33. Correspondingly, the guide seat 2 has a slot 22 through its end face, and the buckle 33 is installed in the slot 22.
[0040] like Figure 3-4 As shown: The impact block is engaged with the guide seat's slot via a latch, increasing its sliding stability within the guide seat and effectively preventing accidental detachment, thus ensuring high safety. Simultaneously, the latch and slot also provide auxiliary guidance, reducing impact block wobbling and ensuring it moves along a defined trajectory, improving the accuracy of the trigger gap.
[0041] The other side of the impact block 3 has a plurality of guide platforms 34 protruding out. Correspondingly, the guide seat 2 is provided with a guide groove 23 through the side wall, and the guide platform 34 is slidably installed in the guide groove 23.
[0042] like Figure 3-4 As shown: The impact block is guided by the guide platform set on it and the guide groove opened in the guide seat. It not only provides guidance and support for the side of the impact block, but also restricts the impact block to move only in the front and back direction, which enhances the stability and smoothness of the impact block sliding back and forth, reduces the swaying or jamming of the impact block during the movement, and thus improves the reliability and adjustment accuracy of the impact block.
[0043] The fixed base 1 has several locking feet 11 on one side, which are connected to the mounting holes 41 on the guide rail 4 to install the fixed base 1 onto the guide rail 4.
[0044] like Figure 1-3 As shown: By precisely aligning and engaging the snap-fit feet with the mounting holes on the guide rail, the trigger's mounting base can be quickly and securely installed or removed from a specific position on the guide rail. The installation process eliminates the need for screws or other fasteners, simplifying the installation steps and improving efficiency. The snap-fit foot-mounting method also facilitates future maintenance or replacement. Compared to traditional screw fixing methods, snap-fit connections are more time-saving and labor-saving, making them particularly suitable for scenarios requiring batch installation.
[0045] In summary: The adjustment knob is rotatably mounted in a rotating groove on the impact block. The knob has an adjustment groove at its bottom, and an adjustment boss is located inside the rotating groove. When the user rotates the adjustment knob, the adjustment groove at the bottom of the knob interacts with the adjustment boss on the impact block, causing relative sliding. Furthermore, the adjustment groove is designed as a spiral groove and is installed with several laterally distributed adjustment bosses. The rotational movement of the adjustment knob is efficiently and stably converted into the linear movement of the impact block along the guide seat by the sliding of the adjustment bosses within the spiral groove. Part of the adjustment knob's structure protrudes from the rotating groove and features an anti-slip tooth design, making it easy for the user to grip and operate, resulting in intuitive and convenient operation.
[0046] By rotating the adjustment knob, users can directly adjust the position of the trigger relative to the guide seat. A more forward-positioned trigger requires a shorter drawer press; a more rearward-positioned trigger requires a longer press. Therefore, by simply rotating the externally visible adjustment knob, users or installers can easily and precisely adjust the trigger's working position, thus flexibly controlling the drawer's trigger gap. This adjustable trigger gap design eliminates the need for repeated adjustments to the overall position of the drawer or guide rails during installation; only minor adjustments to the trigger itself are needed to match different panel gap requirements, greatly simplifying the installation process and improving efficiency. Simultaneously, the ability to precisely control panel gaps enhances the overall aesthetics of the furniture and ensures the reliability of the trigger function, thus making it widely applicable.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
