Description

Technical Field

[0001] This invention relates to the technical field of drawers, and more specifically to a stable connection structure for drawer side panels. Background Technology

[0002] In drawer structures where the panel opens and closes by rotating and flipping, the panel is connected to the left and right side panels via a movable extension mechanism. This structure can be found in Chinese Invention Patent Publication No. CN105231696A, which discloses a drawer with a flip-up panel for shelf mounting. Because this movable extension mechanism only provides a movable fit rather than a rigid fixed connection, the front end of the side panels is not rigidly constrained, and the two side panels are only fixed to the back panel and bottom panel. With this structure, when force is applied to the side panels, the entire side panel can wobble relative to the drawer frame. Therefore, the overall connection rigidity of the side panels is insufficient, and there is still room for further improvement. Summary of the Invention

[0003] This invention proposes a stable connection structure for drawer side panels, which mainly solves the technical problem in existing flip-up drawer panels where the side panel is only fixed to the back panel and bottom panel, and the front end of the side panel lacks rigid constraint, causing the entire side panel to wobble easily when force is applied to it.

[0004] A stable connection structure for a drawer side panel designed for this purpose includes a side panel, on the inner side of which a connector for fixing a divider is provided, and at the end of the divider a mounting fitting is provided. The connector and the assembly are provided with a locking connection structure. When the side plate and the partition are assembled, the connector and the assembly form a locking and positioning fit through the locking connection structure, so that the side plate and the partition can achieve a fastener-free fixed fit connection.

[0005] A guide groove is provided between the connector and the inner side of the side plate. The guide groove is used to guide the assembly on the separator to slide into and be installed on the connector.

[0006] The connector includes a locking part, and the assembly is provided with a plug-in slot and a limiting part; During installation, the locking part and the insertion slot part are inserted and matched, and the locking part is limited between the limiting part and the insertion slot part to form a locking connection structure between the connector and the assembly.

[0007] The connector also includes a fixing part, which is installed on the inner side of the side plate. The end of the locking part extends outward toward the outside of the fixing part and forms a guide groove with the inner side of the side plate.

[0008] The assembly includes a connecting block, one end of which is bent inward to form a limiting part, and a insertion groove for mating with a connecting piece is formed between the connecting block and the limiting part. The connecting block extends laterally toward the outside of the assembly to form a covering structure for covering the outer periphery of the connector.

[0009] The connector is provided with a positioning part; when the assembly is installed in place, the end of the connector block and the positioning part form a limiting fit; the positioning part is used to limit the installation of the assembly, and the positioning part constitutes an anti-detachment structure to prevent the assembly from detaching from the connector.

[0010] The separator is provided with a mounting groove, and the assembly includes a plug block for inserting into the mounting groove, and the plug block is provided with a positioning rib positioned on the inner side of the mounting groove.

[0011] The side plate and the connector are fixedly connected by a first fastener, and the partition and the assembly are fixedly connected by a second fastener. The first fastener, the second fastener, and the locking connection structure are enclosed between the connector and the assembly.

[0012] The side panels are located on the left and right sides of the drawer. The two side panels of the drawer are fixedly connected to both ends of the divider to connect the two side panels of the drawer into one unit. The divider divides the inner cavity of the drawer into two independently spaced storage cavities.

[0013] The drawer includes a base plate, and dividers are supported on or fixedly connected to the base plate; The separator is positioned between the connector and the base plate.

[0014] The beneficial technical effects of the present invention are as follows: 1. The fastener-free connection between the side panel and the divider is achieved through a locking connection structure between the connector and the assembly, effectively solving the technical problem in existing flip-up drawer side panels where the lack of rigid constraint at the front end causes the entire side panel to wobble relative to the drawer frame under manual force. The divider is fixedly connected to the left and right side panels at both ends, forming a rigid connection between them, effectively limiting the wobbling of the side panels under manual force and improving the overall structural stability of the drawer.

[0015] 2. The assembly of the side panel and the divider is achieved through a locking connection structure. During assembly, simply push the fittings at both ends of the divider into the connecting piece along the guide groove to complete the locking. The side panel and the divider are manufactured independently, thus improving the overall assembly efficiency of the drawer.

[0016] 3. The locking part of the connector and the insertion slot of the assembly are interlocked and locked by the limiting part to form a stable and reliable locking connection, ensuring that the connector and the assembly are not easily separated. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. In order to make the above-mentioned objects, features and advantages of this application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0030] See Figures 1-12 A stable connection structure for a drawer side panel includes a side panel 1, wherein a connector 3 for fixing a divider 2 is provided on the inner side of the side panel 1, and a mounting fitting 4 is provided at the end of the divider 2. The connector 3 and the assembly 4 are provided with a locking connection structure. When the side plate 1 and the partition 2 are assembled, the connector 3 and the assembly 4 form a locking and positioning fit through the locking connection structure, so that the side plate 1 and the partition 2 can achieve a fastener-free fixed fit connection.

[0031] The side panel 1 and the partition 2 are locked together by a locking connection structure between the connector 3 and the mounting part 4, achieving a fastener-free fixed connection. During assembly, no screws or other fasteners are needed to fix the side panel 1 and the partition 2. Simply push the mounting part 4 of the partition 2 into the connector 3 to fix the side panel 1 and the partition 2. At the same time, the locking connection structure forms a stable rigid connection between the side panel 1 and the partition 2, effectively limiting the displacement of the partition 2 relative to the side panel 1 and improving the connection rigidity of the front end of the side panel 1 in existing flip-up drawers.

[0032] A guide groove 5 is provided between the connector 3 and the inner side of the side plate 1. The guide groove 5 is used to guide the mounting part 4 on the separator 2 to slide into and be installed on the connector 3.

[0033] The guide groove 5 guides and limits the installation process of the assembly 4, ensuring that the assembly 4 can accurately and smoothly enter the predetermined installation position of the connector 3.

[0034] The connector 3 includes a locking part 302, and the mounting part 4 is provided with a plug-in groove part 401 and a limiting part 402. During installation, the locking part 302 and the insertion slot part 401 are inserted and engaged, and the locking part 302 is limited between the limiting part 402 and the insertion slot part 401 to form a locking connection structure between the connector 3 and the assembly 4.

[0035] The locking connection structure accommodates the locking part 302 through the insertion slot 401 and cooperates with the limiting part 402 to restrict the locking part 302 from disengaging, so that the locking part 302 is firmly constrained between the insertion slot 401 and the limiting part 402, forming a stable locking state and preventing the assembly 4 from loosening from the connector 3.

[0036] The connector 3 also includes a fixing part 301, which is installed on the inner side of the side plate 1. The end of the locking part 302 extends outward toward the outside of the fixing part 301 and forms a guide groove 5 between it and the inner side of the side plate 1.

[0037] The extended locking part 302 makes full use of the space between the fixing part 301 and the side plate 1, so that the connecting part 3 and the inner side of the side plate 1 are provided with a guide groove 5, resulting in a compact structure.

[0038] The assembly 4 includes a connecting block 403, one end of which is bent inward to form a limiting part 402, and a insertion groove 401 for mating with the connector 3 is formed between the connecting block 403 and the limiting part 402. The connecting block 403 extends laterally toward the outside of the assembly 4 to form a covering structure for covering the outer periphery of the connector 3.

[0039] One end of the connecting block 403 is bent inward to form a limiting part 402, and an insertion groove 401 is formed between the connecting block 403 and the limiting part 402. This integral bending structure makes the limiting part 402 and the insertion groove 401 form an integral structure, eliminating the need for additional limiting parts, simplifying the structure of the assembly 4 and reducing manufacturing costs. The connecting block 403 extends laterally outward to form a covering structure. When the assembly 4 and the connector 3 are engaged, the covering structure wraps around the outer periphery of the connector 3, so that the connector 3 is enclosed inside the assembly 4, preventing the connector 3 from being completely exposed. It also increases the contact area between the assembly 4 and the connector 3, making the engagement between the two more stable.

[0040] The connector 3 is provided with a positioning part 303; when the assembly 4 is installed in place, the end of the connector 403 and the positioning part 303 form a limiting fit; the positioning part 303 is used to limit the installation of the assembly 4, and the positioning part 303 constitutes an anti-detachment structure to prevent the assembly 4 from detaching from the connector 3.

[0041] Once the component 4 is installed in place, the end of the connecting block 403 and the positioning part 303 form a limiting fit. The positioning part 303 positions the component 4 to prevent over-installation. At the same time, the positioning part 303 constitutes an anti-detachment structure to prevent the component 4 from detaching from the connector 3. When the component 4 is subjected to an external force in the detachment direction, the end of the connecting block 403 is blocked by the positioning part 303 and cannot detach from the connector 3, thus ensuring the reliability of the connection between the connector 3 and the component 4.

[0042] The positioning part 303 is located on the upper part of the connector 3. When the partition 2 with the fixed assembly 4 moves upward, the connecting block 403 of the assembly 4 will be blocked by the positioning part 303.

[0043] The separator 2 is provided with a mounting groove 201, and the assembly 4 includes a plug block 404 for inserting into the mounting groove 201. The plug block 404 is provided with a positioning rib 405 positioned on the inner side of the mounting groove 201.

[0044] The assembly 4 is inserted into the mounting groove 201 of the partition 2 via the plug-in block 404. The positioning rib 405 on the plug-in block 404 is positioned inside the mounting groove 201, so that the assembly 4 and the partition 2 form a plug-in positioning fit, realizing the positioning installation of the assembly 4 on the partition 2. The fit between the positioning rib 405 and the inside of the mounting groove 201 restricts the relative displacement of the plug-in block 404 in the mounting groove 201, preventing the assembly 4 from moving freely in the mounting groove 201 before tightening the screws.

[0045] The side plate 1 and the connector 3 are fixedly connected by the first fastener 6, and the partition 2 and the assembly 4 are fixedly connected by the second fastener 7. The first fastener 6 and the second fastener 7 are connected to the locking structure and are enclosed between the connector 3 and the assembly 4. The first fastener 6 is a screw, and the second fastener 7 is a screw.

[0046] The side panel 1 and the connector 3 are fixedly connected by the first fastener 6, and the partition 2 and the assembly 4 are fixedly connected by the second fastener 7. The first fastener 6 and the second fastener 7 are covered by the locking structure between the connector 3 and the assembly 4, so that the fasteners are not exposed to the outside of the structure. On the one hand, this effectively protects the fasteners and avoids contact between the human hand and the fasteners. On the other hand, it improves the appearance of the inside of the drawer.

[0047] The side panels 1 are located on the left and right sides of the drawer. The two side panels of the drawer are fixedly connected to the two ends of the divider 2 to connect the two side panels of the drawer into one piece. The divider 2 divides the inner cavity of the drawer into two independently spaced storage cavities.

[0048] The two ends of the divider 2 are fixedly connected to the left and right side panels 1 of the drawer, respectively, connecting the two side panels 1 into one unit. This rigid connection between the left and right side panels 1 through the divider 2 effectively enhances the connection rigidity between the front side panels 1 of the drawer. The divider 2 divides the drawer cavity into two independently spaced storage compartments, realizing the division of the drawer's internal space. Users can place corresponding items into the appropriate storage compartments according to their preferences.

[0049] The drawer includes a base plate 8, and the divider 2 is supported on or fixedly connected to the base plate 8; The divider 2 is positioned between the connector 3 and the base plate 8. Positioning the divider 2 between the connector 3 and the base plate 8 ensures that the divider 2 is confined in the height direction by both the connector 3 and the base plate 8, preventing the divider 2 from moving up and down inside the drawer and ensuring that the divider 2 always remains in the predetermined installation position.

[0050] In this embodiment, the base plate 8 and the side plate 1 can be fixedly connected by screws. The bottom of the divider 2 may not be fixedly connected to the base plate 8; the bottom of the divider 2 is only supported on the base plate 8. The divider 2 is inserted into the guide groove 5 from bottom to top (slid into the guide groove 5 from the bottom of the drawer). When the divider 2 is in place, the connecting block 403 abuts against the positioning part 303, and then the base plate 8 is locked, so that the divider 2 cannot be removed from the drawer. Alternatively, the bottom of the divider 2 can be fixedly connected to the base plate 8 by screws to prevent the base plate 8 from sagging and deforming.

[0051] In this embodiment, the side plate 1 has a cavity 101, and a fixing bracket 9 is installed in the cavity 101. The fixing bracket 9 has three threaded holes spaced vertically apart. The side plate 1 has three first through holes on its inner side, and the fixing part 301 of the connector 3 has three second through holes. The side plate 1 has positioning holes on its inner side, and the fixing part 301 of the connector 3 has corresponding positioning pins for insertion into the positioning holes. The first fastener 6 is a screw, and there are three screws. During installation, the positioning pins are inserted into the positioning holes, and each screw passes through the second through hole and the first through hole and is inserted into the corresponding threaded hole, so that the connector 3 is fixed on the side plate 1. The fixing part 301 has a countersunk groove corresponding to the second through hole, and the head of the screw is limited in the countersunk groove to prevent the head of the screw from protruding.

[0052] In this embodiment, the mounting groove 201 of the separator 2 is provided with three screw cavities 202 arranged vertically and horizontally. There are two plug-in blocks 404, which are arranged vertically and horizontally. A screw hole with a countersunk groove is provided between the two plug-in blocks 404, which passes through the groove surface of the plug-in groove 401. The upper end of the assembly 4 is provided with a protrusion 406, which is provided with a screw hole with a countersunk groove. The lower part of the assembly 4 is provided with a screw hole with a countersunk groove. When the assembly 4 is fixed, each screw is inserted into the screw hole and the screw cavity 202 in sequence.

[0053] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
