Description

Technical Field

[0001] The utility model relates to a drawer, and more specifically to a drawer frame connection structure and an assembled drawer. Background Art

[0002] Drawers are the most common storage components in furniture storage. They can effectively store items and are convenient for pushing and pulling. They have good dustproof and concealing effects. At present, most drawers on the market are assembled from composite panels, which have defects such as easy deformation, difficult cleaning, and poor environmental protection. Therefore, people are increasingly favoring drawers made of aluminum.

[0003] Most existing aluminum drawers are assembled by splicing together loose profiles, which is a cumbersome process and can easily cause large seams at the edges after installation. At the same time, the connection holes on the drawers are generally exposed, which affects the appearance. Over time, they are prone to dust accumulation and are difficult to clean, which seriously reduces the user experience.

[0004] Chinese patent application No. 202310540236.3 discloses a "method and system for constructing a thin-walled aluminum profile drawer with concealed corner connectors and two-way drawer front adjustment". The publication date of the patent application is July 25, 2023. Its thin-walled aluminum profile drawer includes left / right profiles, front / rear profiles, front base profiles, middle base profiles and rear base profiles, and multiple concealed corner connectors. The multiple concealed corner connectors are inserted and fastened into the router area of ​​the profile; multiple connectors are inserted and fastened into the free space of the profile. The above-mentioned aluminum profile drawer can hide the corner connectors, making the drawer more beautiful as a whole. However, the corner connector is inserted into the profile, and there is no other fastener connection between the two. The stability of the connection needs to be verified, and it is easy to produce large joints under the action of external forces.

The front corner code connector 1 is provided with a transverse pin 1-1 that can be inserted into the end cavity of the transverse frame 3 and a longitudinal pin 1-2 that can be inserted into the end cavity of the longitudinal frame 4. For a rectangular drawer, the transverse frame 3 and the longitudinal frame 4 are perpendicular to each other, so the transverse pin 1-1 and the longitudinal pin 1-2 on the front corner code connector 1 are also perpendicular to each other. The transverse frame 3 and the longitudinal frame 4 are connected by the front corner code connector 1 and fastened with fasteners, so that the corner connection of the transverse frame 3 and the longitudinal frame 4 is realized, and the connection structure is stable. A door panel mounting hole 3-2 is provided on the end side wall of the transverse frame 3, and the door panel 10 can be installed on the transverse frame 3 through the door panel mounting hole 3-2. According to different use occasions of the drawer, the drawer has two designs, one with or without a door panel. In order to adapt to the form of different drawers, the outer side of the transverse frame 3 is selectively provided with a door panel 10 or an outer cover panel 6 covering the outer side of the end of the transverse frame 3. The door panel 10 and the outer cover panel 6 are both fixed by fasteners passing through the door panel mounting hole 3-2, that is, for a drawer with a door panel, the outer side of the transverse frame 3 can be used to install the door panel 10 through the door panel mounting hole 3-2, and for a drawer without a door panel, the outer side of the end of the transverse frame 3 can be installed through the door panel mounting hole 3-2 to cover the connection hole. In addition, an inner cover panel 7 covering the door panel mounting hole 3-2 is detachably provided on the inner side of the end of the transverse frame 3, and each connection hole can be covered and hidden by the inner and outer cover panels, making the drawer look more exquisite and complete, greatly improving the user experience. The inner cover 7 adopts a detachable design. The corresponding connection holes and fasteners can be exposed by removing the inner cover 7, which facilitates the disassembly and assembly of the door panel 10 and the outer cover 6. The inner cover 7 covers the connection holes from the inside, making the inside of the drawer tidy and convenient for maintenance.

[0047] like Figure 3As shown, the connection between the frames is as follows: a screw groove 4-2 is provided in the end cavity of the longitudinal frame 4, a frame connection hole 1-3 corresponding to the screw groove 4-2 is provided on the front corner code connector 1, and a locking hole 3-1 corresponding to the frame connection hole 1-3 is provided on the end side wall of the transverse frame 3, and the locking hole 3-1, the frame connection hole 1-3 and the screw groove 4-2 are locked and fixed by the frame connection screw 8. When installing, the transverse pin 1-1 of the front corner code connector 1 is inserted into the end cavity of the transverse frame 3, and the longitudinal pin 1-2 of the front corner code connector 1 is inserted into the end cavity of the longitudinal frame 4. At this time, the locking hole 3-1, the frame connection hole 1-3 and the screw groove 4-2 are just opposite, and then the frame connection screw 8 is screwed in from the outside of the transverse frame 3, and the frame connection screw 8 passes through the locking hole 3-1 and the frame connection hole 1-3 and then matches with the screw groove 4-2 thread. The frame connection screw 8 may be a self-tapping screw, and the screw groove 4-2 may be a circular or C-shaped hole formed on the longitudinal frame 4. With this structure, the front corner code connector 1, the transverse frame 3 and the longitudinal frame 4 can be connected simultaneously through the frame connection screw 8, and the installation is simpler and more convenient, and the connection is firm and reliable. Since the frame connection screw 8 is connected from the outside of the transverse frame 3, the frame connection screw 8 is exposed on the outside of the transverse frame 3. When the door panel 10 is installed, the frame connection screw 8 can be covered by the door panel 10, and when there is no door panel, the frame connection screw 8 can be covered by the outer cover plate 6.

[0048] like Figure 2 and Figure 4 As shown, in this embodiment, the transverse pin 1-1 of the front corner code connector 1 is also provided with an outer cover plate connecting hole 1-4 corresponding to the above-mentioned door panel mounting hole 3-2. After the transverse pin 1-1 is inserted into the end cavity of the transverse frame 3, the outer cover plate connecting hole 1-4 is exactly opposite to the door panel mounting hole 3-2. The fastener passes through the door panel mounting hole 3-2 and the outer cover plate connecting hole 1-4 from the inner side of the transverse frame 3 to connect the door panel 10 or the outer cover panel 6. At this time, the transverse pin 1-1 serves as an intermediate filler to prevent the transverse frame 3 from being compressed and deformed during the screw tightening process, and at the same time, it can improve the firmness of the screw tightening to ensure that the door panel 10 or the outer cover panel 7 is firmly installed. Figure 5 and Figure 6As shown, the inner side of the outer cover plate 6 is provided with a screw column 6-1 which can be inserted into the corresponding outer cover plate connecting hole 1-4, and the screw column 6-1 is provided with an outer cover plate connecting screw 9 which passes through the inner door panel mounting hole 3-2. The screw column 6-1 can be inserted into the outer cover plate connecting hole 1-4, and the outer cover plate connecting screw 9 is directly screwed into the screw column 6-1 to achieve connection and fixation. The above-mentioned outer cover plate connecting hole 1-4 and the door panel mounting hole 3-2 are both waist-shaped holes, which can facilitate the fine adjustment of the installation position of the door panel 10 and ensure the assembly accuracy of the drawer. Correspondingly, wing plates are provided on both sides of the above-mentioned screw column 6-1, which can improve the structural strength of the screw column 6-1 on the outer cover plate 6 on the one hand, and can stably cooperate with the above-mentioned waist-shaped holes on the other hand. Refer to Figure 5 and Figure 6 As shown, the edge of the outer cover plate 6 is also provided with a plurality of edge buckles 6-2 that can be buckled on the front corner bracket connector 1, which can prevent the edge of the outer cover plate 6 from warping, and further improve the installation stability of the outer cover plate 6. During the specific installation, the outer cover plate 6 is fitted from the outside of the front end of the drawer toward the surface of the front corner bracket connector 1 and the horizontal frame 3, so that the screw column 6-1 is plugged into the waist-shaped hole on the front corner bracket connector 1 and fastened with screws, and at the same time, the edge buckles 6-2 are also clamped and limited with the side wall of the front corner bracket connector 1 and the bottom of the horizontal frame 3, and finally the outer cover plate 6 is installed to cover the outside of the drawer.

[0049] like Figures 7 to 9 As shown, in this embodiment, a plurality of ball studs 7-1 are provided on the inner side of the inner cover plate 7, an inner cover plate connecting hole 1-5 is provided on the transverse pin 1-1 of the front angle code connector 1, and a through hole 3-3 corresponding to the inner cover plate connecting hole 1-5 is provided on the inner side of the end of the transverse frame 3, and the ball studs 7-1 can pass through the through hole 3-3 and snap into the corresponding inner cover plate connecting hole 1-5. With this structure, the inner cover plate 7 is firmly installed and easy to disassemble and assemble. Specifically, the ball head of the ball head column 7-1 is a hollow structure, which can be squeezed and deformed toward the center when subjected to pressure, and can rebound after the pressure is eliminated. When the inner cover plate 7 is installed, the ball head column 7-1 is aligned with the corresponding through hole 3-3 and inserted. Since the inner cover plate connection hole 1-5 corresponds to the position of the through hole 3-3, the ball head column 7-1 can be inserted into the inner cover plate connection hole 1-5. The inner cover plate connection hole 1-5 is large at one end close to the outside of the drawer, and small at the other end, forming a trumpet-shaped stepped hole. The ball head column 7-1 is inserted from the small end, and rebounds after entering the other end to achieve engagement. During specific installation, the inner cover plate 7 is fitted from the inner side of the front end of the drawer toward the surface of the front corner code connector 1 and the horizontal frame 3, so that the ball head column 7-1 is embedded and clamped into the inner cover plate connection hole 1-5 after deformation.

[0050] In addition, if Figure 5 and Figure 8As shown, for a drawer with a large height span of the horizontal frame 3 and a gap in the middle, the inner side of the outer cover 6 is further provided with a first pair of inserting parts 6-3, the side wall of the first pair of inserting parts 6-3 is provided with a first buckle part 6-4, the inner side of the inner cover 7 is provided with a second pair of inserting parts 7-2, the side wall of the second pair of inserting parts 7-2 is provided with a second buckle part 7-3, the first pair of inserting parts 6-3 and the second pair of inserting parts 7-2 are plugged through the horizontal frame 3, and the first buckle part 6-4 and the second buckle part 7-3 are buckled together. The inner and outer cover plates can be buckled together, which further improves the installation stability of the inner cover plate 7. Specifically, the first pair of inserting parts 6-3 can be a rectangular frame protruding from the inner surface of the outer cover 6, and the second pair of inserting parts 7-2 can be a rectangular frame protruding from the inner surface of the inner cover 7. The inner size of the second pair of inserting parts 7-2 is matched with the outer size of the first pair of inserting parts 6-3, so that the first pair of inserting parts 6-3 can be inserted into the second pair of inserting parts 7-2; the first buckle part 6-4 can be a buckle provided on the side wall of the first pair of inserting parts 6-3, and the second buckle part 7-3 can be a slot provided on the side wall of the second pair of inserting parts 7-2. After the first pair of inserting parts 6-3 and the second pair of inserting parts 7-2 are plugged in, the first buckle part 6-4 and the second buckle part 7-3 are engaged with each other, and finally the inner cover 7 is covered and installed to the inside of the drawer. In addition, Figure 8 and Fig.10 As shown, a disassembly groove 7-4 is provided on one side of the inner cover plate, which can facilitate the disassembly of the inner cover plate 7. If the user needs to disassemble the inner cover plate 7 during use, the user can use a tool to pry up the inner cover plate 7 from the disassembly groove 7-4 to loosen the fit between the ball head columns and the buckles, and then remove the inner cover plate 7, thereby facilitating the disassembly and assembly of the screws.

[0051] Fig.11 The state of the drawer with the outer cover plate 6 installed is shown. After both the outer cover plate 6 and the inner cover plate 7 are installed, the connection holes on the drawer can be effectively covered, the problem of exposed screws is solved, the appearance of the drawer is more exquisite and complete, and the user experience is greatly improved.

[0052] Fig.12 The state of the drawer with the door panel 10 installed is shown. If the user needs to install the drawer door panel during use, the user can choose to remove the outer cover plate 6, that is, remove the inner cover plate 7 and the outer cover plate 6 respectively, and then use screws to fix the door panel 10 on the drawer through the door panel installation holes 3-2 on the horizontal frame 3, and then install the inner cover plate 7 to the inside of the drawer, which can also achieve effective coverage of the connection holes.

[0053] This embodiment also relates to an assembled drawer. Figure 1 , Fig.11 and Fig.12As shown, the assembled drawer includes a pair of transverse frames 3 and a pair of longitudinal frames 4, which enclose the frame structure of the drawer. A bottom plate 5 is provided at the bottom of the frame structure.
