Abstract
Description
Technical Field
[0001] This utility model relates to the field of drawer connectors, and in particular to a drawer connection structure. Background Technology
[0002] Drawer connection structures are primarily used to connect the drawer front panel and side panels. Traditionally, these are connected using corner brackets, with the front end of the bracket fixed to the inside of the front panel by screws, and one side of the bracket fixed to the inside of the side panel by screws. However, with this connection structure, the screw holes are prone to loosening during drawer use, leading to large gaps between the front panel and side panel. Some drawer connection structures on the market also use top and bottom screw-on mechanisms. Since both the top and bottom screw-on mechanisms have U-shaped slots and protruding locking feet, and these slots and feet are tightly fitted to the top and bottom screw-on mechanisms, disassembly can be inconvenient. Utility Model Content
[0003] The purpose of this utility model is to provide a drawer connection structure that can avoid large gaps between the front panel and the side panel and is easy to disassemble.
[0004] The drawer connection structure of this utility model includes a front connector and a connecting seat. The front connector is provided with an upper pin and a lower pin with a slot. The front end of the lower pin is a triangular insertion part. A first retaining shaft is provided at the front end of the slot of the triangular insertion part. A stop is provided at the rear end of the slot of the triangular insertion part. An adjusting component is installed on the connecting seat. A lower screw is hinged to the adjusting component. The lower screw is hinged to one end of a connecting rod. An upper screw is hinged to the other end of the connecting rod. One side of the upper screw is hinged to the connecting seat. The lower screw has a retaining foot that is inserted into the slot of the triangular insertion part. A protrusion that abuts against the stop is provided in front of the retaining foot. A U-shaped slot that engages with the first retaining shaft is provided behind the retaining foot. A torsion spring is also connected to one side of the lower screw. The other end of the torsion spring is installed on the adjusting component. The upper pin is a rectangular pin. A second retaining shaft is provided at the front end of the slot of the rectangular pin. The upper screw has a Y-shaped slot. A rod on one side of the Y-shaped slot is inserted into the slot of the rectangular pin, so that the second retaining shaft engages in the Y-shaped slot.
[0005] As a preferred embodiment of this utility model, the lower screw buckle includes a rotating slider, which is hinged to the adjusting member via a first rotating shaft. The locking foot and U-shaped locking groove are located at the bottom of the rotating slider. An arc-shaped rotating arm with a forward tilt extends upward from one side of the upper part of the rotating slider. The arc-shaped rotating arm is hinged to the connecting rod via a second rotating shaft. An arc-shaped slot is provided on the other side of the rotating slider along the longitudinal direction. A locking hole is provided on the rotating slider near the arc-shaped slot. One end of the torsion spring is hooked into the locking hole and fixed to the rotating slider.
[0006] As a preferred embodiment of this utility model, the adjusting component is provided with a longitudinal screw hole that matches the arc-shaped slot. The adjusting component is tightened and fixed to the connecting seat by fastening screws that pass through the arc-shaped slot and exit through the longitudinal screw hole. The rotating slider causes the arc-shaped slot to rotate along with the fastening screws as the first rotating shaft rotates.
[0007] As a preferred embodiment of this utility model, a slot for inserting the lower pin is provided on one side of the adjusting member.
[0008] As a preferred embodiment of this utility model, the back of the adjusting member is provided with a slider, and the connecting seat that cooperates with the slider is provided with a longitudinal groove.
[0009] As a preferred embodiment of this utility model, the adjusting component is provided with a transverse hole, and an eccentric wheel screw is inserted into the transverse hole to fix the adjusting component on the connecting seat.
[0010] As a preferred embodiment of this utility model, the adjusting component is provided with a torsion spring mounting seat, and the end of the torsion spring is fitted into the torsion spring mounting seat for fixation.
[0011] As a preferred embodiment of this utility model, the upper swivel extends downward with a rearward-inclined arc-shaped swivel arm, which is hinged to the connecting rod via a third pivot.
[0012] As a preferred embodiment of this utility model, the blocking component is an adjusting screw.
[0013] The drawer connection structure of this utility model involves the front connector pushing the lower pin into the lower snap fastener, allowing the locking pin to be inserted into the slot of the triangular insertion part. The first locking shaft engages in the U-shaped slot, causing the lower end of the connecting rod to swing. At this time, the rectangular pin of the front connector allows one side of the upper snap fastener's Y-shaped slot to be inserted from the slot of the rectangular pin, and the second locking shaft engages in the Y-shaped slot. The upper end of the connecting rod then swings, keeping the torsion spring in a tensioned state, thereby tightening the panel and side panel and reducing the gap between them. Furthermore, since the upper pin is a rectangular pin, it cooperates with the Y-shaped slot of the upper snap fastener. Only the second locking shaft engages in the Y-shaped slot, making it easier to install and remove the drawer by engaging and removing the second locking shaft along the oblique side of the Y-shaped slot.

[0015] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0016] In this utility model, it should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
[0017] A drawer connection structure, such as Figure 1-6 As shown, it includes a front connector 1 and a connecting base 2. The front connector is provided with an upper pin 4 and a lower pin 5 with a slot 3. The front end of the lower pin is a triangular insertion part. A first retaining shaft 6 is provided at the front end of the slot of the triangular insertion part. A stopper 7 is provided at the rear end of the slot of the triangular insertion part. An adjusting member 8 is installed on the connecting base. A lower screw 9 is hinged to the adjusting member. The lower screw 9 is hinged to one end of a connecting rod 10. An upper screw 11 is hinged to the other end of the connecting rod. One side of the upper screw 11 is hinged to the connecting base. The lower screw 11 has a three-pronged... The angular insertion part has a slot for inserting a locking foot 12. The front of the locking foot has a protrusion 13 that abuts against the stopper. The rear of the locking foot has a U-shaped slot 14 for engaging the first locking shaft. A torsion spring 15 is also connected to one side of the lower screw fastener. The other end of the torsion spring is installed on the adjusting part. The upper insertion foot is a rectangular insertion foot. A second locking shaft 16 is provided at the front end of the slot of the rectangular insertion foot. The upper screw fastener has a Y-shaped slot 17. A rod on one side of the Y-shaped slot is inserted from the slot of the rectangular insertion foot, so that the second locking shaft is engaged in the Y-shaped slot.
[0018] The front end of the front connector 1 is fixed to the inside of the drawer panel by screws or bolts through the mounting hole 34. The rear end of the front connector extends towards the connecting seat 2 with an upper pin 4 and a lower pin 5 having a slot 3. The front connector pushes the lower pin into the lower screw, allowing the pin 12 to be inserted into the slot of the triangular insertion part. The first locking shaft engages with the U-shaped slot 14, causing the lower end of the connecting rod to swing. At this time, the rectangular pin of the front connector allows one side of the upper screw's Y-shaped slot to be inserted from the slot of the rectangular pin. The second locking shaft engages with the Y-shaped slot, and the upper end of the connecting rod swings, keeping the torsion spring in a tensioned state, thereby tightening the panel and side panel and reducing the gap between the panel and side panel. Furthermore, since the upper pin is a rectangular pin, it cooperates with the Y-shaped slot of the upper screw. Only the second locking shaft engages with the Y-shaped slot. During installation and disassembly, the second locking shaft engages and disassembles along the inclined side of the Y-shaped slot, making disassembly more convenient. In addition, the stop 7 on the front connector is an adjusting screw. By adjusting the screw, the depth of the front connector in the adjusting screw hole is changed, so that the end of the adjusting screw presses against the adjusting component, thereby moving the front connector outward or inward relative to the adjusting component, i.e. the connecting seat, and thus achieving fine adjustment of the left and right position of the drawer panel.
[0019] The lower screw 9 includes a rotating slider 18, which is hinged to the adjusting member 8 via a first rotating shaft 19. One end of a torsion spring hooks into a locking hole 23 on the rotating slider, and the other end is fitted into a torsion spring mounting seat 31 and fixed to the adjusting member. A locking foot and a U-shaped locking groove are located at the bottom of the rotating slider. An arc-shaped rotating arm 20 extends upwards from one side of the upper part of the rotating slider and is hinged to a connecting rod via a second rotating shaft 21. Additionally, the other side of the rotating slider has an arc-shaped slot 22 along the longitudinal direction that mates with the longitudinal screw hole 24 on the adjusting member. After the fastening screw 25 is screwed into the longitudinal screw hole 24, the rotating slider, under the rotation of the first rotating shaft, allows the arc-shaped slot to rotate along with the fastening screw 25.
[0020] The upper screw 11 is hinged on one side to the mounting position of the connecting seat via a pivot 35. The upper screw extends downward with a backward-inclined arc-shaped screw arm 32, which is hinged to the connecting rod via a third pivot 33.
[0021] The adjusting component 8 is mounted on the connecting seat via a slider 27 within a longitudinal groove 28. It is secured to the connecting seat by a fastening screw 25 that passes through an arc-shaped slot and exits through a longitudinal screw hole 24. Simultaneously, an eccentric wheel screw 30 passes through a transverse hole 29 to further secure it to the connecting seat. Loosening the eccentric wheel screw allows the adjusting component to move up and down relative to the connecting seat on the slider and longitudinal screw hole, thus enabling fine-tuning of the drawer panel's vertical position. Additionally, a slot 26 for inserting a lower pin is provided on one side of the adjusting component.
[0022] The back of the connecting seat 2 is fixed to the inside of the side plate with screws. After the adjusting piece 8, the lower buckle 9, and the upper buckle 11 are installed on the connecting seat, the upper pin 4 of the front connector 1 is inserted into the socket of the connecting seat, the lower pin 5 is inserted into the slot 26 of the adjusting piece, and the locking pin 12 of the lower buckle is inserted into the slot of the triangular insertion part of the lower pin 5. The first locking shaft of the lower pin is locked into the U-shaped slot 14. At this time, the lower buckle rotates on the first rotating shaft by rotating the slider, and the arc-shaped buckle arm 32 swings forward, thereby driving the lower end of the connecting rod to swing forward. At this time, the second locking shaft of the upper pin is also locked into the Y-shaped slot of the upper buckle. The upper end of the connecting rod pushes up the arc-shaped buckle arm 32. With the torsion spring tightening the side of the rotating slider, the Y-shaped slot side of the upper buckle tightens the second locking shaft, making the panel and the side plate tight, thereby reducing the gap between the panel and the side plate. Furthermore, since the upper pin is a rectangular pin, it matches the Y-shaped slot of the upper screw. Only the second locking shaft is inserted into the Y-shaped slot. During installation and disassembly, the second locking shaft can be easily inserted and removed along the inclined side of the Y-shaped slot, making disassembly more convenient.
[0023] The above embodiments are only used to illustrate the detailed solution of this utility model. This utility model is not limited to the above detailed solution, that is, it does not mean that this utility model must rely on the above detailed solution to be implemented. Those skilled in the art should understand that any improvement to this utility model, equivalent substitution of the raw materials of this utility model product, addition of auxiliary components, selection of specific methods, etc., all fall within the protection scope and disclosure scope of this utility model.
