The upper rotary buckle is hinged to the lower rotary buckle through a connecting rod. One end of the connecting rod is hinged to the upper rotary buckle, and the other end of the connecting rod is hinged to the lower rotary buckle. The elastic locking component is located on one side of the lower rotary buckle.

[0005] When the front connector is inserted into the connecting component, the front connector abuts against the upper rotary buckle and causes the upper rotary buckle to rotate, driving the connecting rod to rotate. The lower rotary buckle rotates accordingly and is inserted into the front connector. The elastic locking component abuts against the lower rotary buckle.

[0006] When the front connector is forcibly disassembled, the elastic locking component blocks the reverse rotation of the lower rotary buckle, so that the front connector is clamped in the lower rotary buckle.

[0007] As a preferred solution, the upper rotary buckle includes a first rotating plate and a second rotating plate rotatably connected to the main board. The first rotating plate abuts against the second rotating plate. The second rotating plate is hinged to the connecting rod. When the front connector is inserted into the connecting component, the front connector abuts against the first rotating plate and drives the first rotating plate to rotate. The second rotating plate rotates accordingly and is inserted into the front connector.

[0008] As a preferred solution, the lower turnbuckle includes a turnbuckle body, a connecting portion and a rotating ring. The connecting portion and the rotating ring are respectively fixedly connected to both ends of the turnbuckle body. The turnbuckle body abuts against the elastic locking assembly. The connecting rod is rotatably connected to the connecting portion, and the rotating ring is slidably connected to the main board.

[0009] As a preferred solution, the turnbuckle body protrudes outwardly with an abutting portion, and the turnbuckle body abuts against the elastic locking assembly through the abutting portion.

[0010] As a preferred solution, the elastic locking assembly includes a torsion spring and a spring piece. One end of the torsion spring is connected to the main board, and the other end of the torsion spring is connected to the lower turnbuckle.

[0011] The spring piece includes a spring piece body fixedly installed on the main board and an elastic free end fixedly connected to one end of the spring piece body. When the front connection code is inserted into the connection assembly, the elastic free end abuts against the lower turnbuckle.

[0012] As a preferred solution, the front connection code includes a connecting strip and two card insertion members. Each card insertion member is distributed along the length direction of the connecting strip and is fixedly connected to the same side of the connecting strip. A socket for inserting the lower turnbuckle is provided on any one of the card insertion members.

[0013] As a preferred solution, an adjusting bolt is further included. An adjusting through hole is provided on the card insertion member, and the adjusting bolt is screwed into the adjusting through hole. By adjusting the depth of the adjusting bolt inserted into the adjusting through hole, the end of the adjusting bolt presses against the main board to the left or right, so as to realize the left and right movement of the front connection code relative to the main board.

[0014] As a preferred solution, the main board is installed on the drawer side plate through a fixing plate. The fixing plate is installed on the drawer side plate, and the main board is connected to the fixing plate through an up and down adjusting member and can move up and down relative to the fixing plate.

[0015] As a preferred solution, the fixing plate is provided with mounting holes, and the main board is provided with elongated through holes.

[0016] In order to solve the same technical problem, the present invention further provides a drawer, which includes a drawer panel, a drawer side plate and a connecting device of the drawer panel as described in any of the above solutions. The front connection code of the connecting device of the drawer panel is connected to the drawer panel, and the main board is connected to the drawer side plate.

[0017] Compared with the prior art, the connecting device of the drawer panel and the drawer of the embodiment of the present invention have the following beneficial effects: the connecting device of the drawer panel is a heightened type, and two buckles, an upper buckle and a lower buckle, are provided on the main board, and the two are connected by a connecting rod. When any buckle rotates, the other buckle can be driven to rotate accordingly, and the lower buckle is pluggably connected to the front connection code. The elastic locking component is used to abut the lower buckle to prevent the lower buckle from rotating. When the front connection code is inserted into the connecting component, the front connection code hits the upper buckle, and the connecting rod and the lower buckle rotate accordingly. The lower buckle is inserted into the front connection code and abuts with the elastic locking component, so that the front connection code is fastened in the connecting component, and the drawer panel is connected with the drawer side plate. When disassembling the front connection code, the elastic locking component must be firstly moved so that it does not abut with the lower buckle, and the lower buckle is driven to rotate, so that the connecting rod and the upper buckle rotate, and the front connection code is ejected. Otherwise, the elastic locking component is always abutted with the lower buckle, so that the lower buckle cannot rotate in the reverse direction. The connecting device of the drawer panel can realize the connection and separation between the drawer panel with a higher height and the drawer side panel, simplifying the operation of assembling and disassembling the drawer, and the connecting device of the drawer panel can be used repeatedly.

Detailed implementation mode

[0026] The following combines the accompanying drawings and embodiments to further describe in detail the specific implementation mode of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0027] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "bottom", etc. used in the present invention indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0028] It should be understood that the terms "first", "second", etc. used in the present invention are used to describe various information, but these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, "first" information can also be called "second" information, and similarly, "second" information can also be called "first" information.

[0029] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0030] Such as Figures 1 to 7As shown in the figure, a connecting device for a drawer panel according to a preferred embodiment of the present invention includes a connecting component and a front connecting code 4 fixedly connected to the drawer panel 1. The connecting component is detachably connected to the front connecting code 4. The connecting component includes a main board 3 installed on the drawer side plate 2. The main board 3 is provided with an upper rotating buckle 5, a lower rotating buckle 6 and an elastic locking component 7. The upper rotating buckle 5 and the lower rotating buckle 6 are distributed along the length direction of the main board 3 and are rotatably connected to the main board 3. The upper rotating buckle 5 is hinged to the lower rotating buckle 6 through a connecting rod 8. One end of the connecting rod 8 is hinged to the upper rotating buckle 5, and the other end of the connecting rod 8 is hinged to the lower rotating buckle 6. The elastic locking component 7 is located on one side of the lower rotating buckle 6. When the front connecting code 4 is inserted into the connecting component, the front connecting code 4 abuts against the upper rotating buckle 5, causing the upper rotating buckle 5 to rotate, driving the connecting rod 8 to rotate, and the lower rotating buckle 6 to rotate accordingly and be inserted into the front connecting code 4. The elastic locking component 7 abuts against the lower rotating buckle 6. When the front connecting code 4 is forcibly disassembled, the elastic locking component 7 blocks the reverse rotation of the lower rotating buckle 6, so that the front connecting code 4 is clamped in the lower rotating buckle 6.

[0031] Based on the above technical solution, since the connecting device of the drawer panel is a heightened model and is used to connect the relatively high drawer panel 1 and the drawer side panel 2, the connecting component includes two rotary buttons, upper and lower. Both rotary buttons are hinged to the main board 3 through a cylindrical hinge 15 and are connected to each other through a connecting rod 8. When the upper rotary button 5 is pushed, the upper rotary button 5 rotates, driving the cylindrical hinge 15 to rotate, and the connecting rod 8 rotates accordingly, so that the lower rotary button 6 rotates on the main board 3, realizing the pluggable connection between the lower rotary button 6 and the front connection code 4. An installation position 16 matching the front connection code 4 is provided on the main board 3. The front connection code 4 is inserted into the installation position 16 to realize the detachable connection between the front connection code 4 and the main board 3. Since the front connection code 4 is connected to the drawer panel 1 and the main board 3 is installed on the drawer side panel 2, the drawer panel 1 and the drawer side panel 2 can be detachably connected, facilitating the installation and disassembly of relatively high drawers. Before the connecting component contacts the front connection code 4, the elastic locking component 7 does not contact the lower rotary button 6, and the upper rotary button 5, the connecting rod 8, and the lower rotary button 6 can all rotate. When the front connection code 4 pushes the first rotating plate 51, when the front connection code 4 is inserted into the installation position 16, the front connection code 4 touches and pushes the upper rotary button 5. The upper rotary button 5 rotates counterclockwise and drives the connecting rod 8 to rotate, causing the lower rotary button 6 hinged to the end of the connecting rod 8 away from the upper rotary button 5 to rotate clockwise and insert into the front connection code 4. At this time, the elastic locking component 7 abuts against the lower rotary button 6 that has rotated clockwise, preventing it from rotating counterclockwise, thus clamping the front connection code 4 and realizing the locking of the front connection code 4 and the connecting component. If the front connection code 4 is forcibly disassembled roughly, since the elastic locking component 7 abuts against the lower rotary button 6, the lower rotary button 6 cannot rotate in the reverse direction and cannot be pulled out of the front connection code 4, making the front connection code 4 locked with the connecting component. If it is necessary to disassemble the front connection code 4, it is necessary to utilize the elastic force of the elastic locking component 7 to push aside the elastic locking component 7 so that the elastic locking component 7 no longer abuts against the lower rotary button 6. At the same time, rotate the lower rotary button 6 counterclockwise so that the lower rotary button 6 is no longer inserted into the front connection code 4, and then pull out the front connection code 4 to realize the separation of the drawer panel 1 and the drawer side panel 2. This structure can repeatedly insert and remove the front connection code 4, and the connecting device of this drawer panel can be used multiple times, mainly applicable to relatively high drawers, which is beneficial to the assembly and disassembly of the drawer panel 1 and the side panel.

[0032] Among them, the upper rotating buckle 5 includes a first rotating plate 51 and a second rotating plate 52 that are rotatably connected to the main board 3. The first rotating plate 51 abuts against the second rotating plate 52, and the second rotating plate 52 is hinged to the connecting rod 8. When the current front connector 4 is inserted into the connecting component, the front connector 4 abuts against the first rotating plate 51 and drives the first rotating plate 51 to rotate. The second rotating plate 52 rotates accordingly and is inserted into the front connector 4. The shape of the first rotating plate 51 is similar to an ellipse, and the shape of the second rotating plate 52 is an irregular shape. One end of the second rotating plate 52 is hinged to the main board 3 through a cylindrical hinge 15, and the other end is detachably connected to the front connector 4, and one side thereof abuts against the first rotating plate 51. When the front connector 4 pushes the first rotating plate 51, due to the abutment between the first rotating plate 51 and the second rotating plate 52, the first rotating plate 51 is pushed and rotates counterclockwise, driving the second rotating plate 52 to rotate counterclockwise and inserting it into the front connector 4 to achieve fastening, so that the front connector 4 is fastened to the connecting component both above and below, strengthening the connection between the front connector 4 and the connecting component and making it more difficult to forcibly disassemble the front connector 4.

[0033] Specifically, the lower rotating buckle 6 includes a rotating buckle body 61, a connecting portion 62, and a rotating ring 63. The connecting portion 62 and the rotating ring 63 are respectively fixedly connected to both ends of the rotating buckle body 61, and the rotating buckle body 61, the connecting portion 62, and the rotating ring 63 are integrally formed. One side of the rotating buckle body 61 abuts against the elastic locking component 7, and a clamping portion 17 protrudes from the other side of the rotating buckle body 61. The other side of the rotating buckle body 61 is detachably connected to the front connector 4 through the clamping portion 17. The shape of the connecting portion 62 is strip-shaped, and it is rotatably connected to the other end of the connecting rod 8 through a cylindrical hinge 15. The shape of the rotating ring 63 is an elliptical ring, and it is slidably connected to the main board 3. When the connecting rod 8 drives the lower rotating buckle 6 to rotate, the connecting portion 62 rotates with the connecting rod 8, and the rotating buckle body 61 rotates accordingly. One side of it abuts against the elastic locking component 7 to achieve inserting into the front connector 4, and the rotating ring 63 rotates and slides counterclockwise on the main board 3. The shape of the lower rotating buckle 6 is an irregular figure. Through the rotating buckle body 61, the connecting portion 62, and the rotating ring 63, the lower rotating buckle 6 rotates and slides on the main board 3, contacts the elastic locking component 7, and is detachably connected to the front connector 4. In this embodiment, a cross-shaped hole 18 matching a screwdriver is opened on the rotating buckle body 61. The user inserts the screwdriver into the cross-shaped hole 18 to twist the rotating buckle body 61 to achieve the clockwise rotation of the lower rotating buckle 6 and pull out the clamping portion 17 from the front connector 4. More specifically, an abutting portion 64 protrudes outward from the rotating buckle body 61. The abutting portion 64 is a small protrusion on the rotating buckle body 61. Abutting surfaces are provided on one side of the abutting portion 64 close to the elastic locking component 7, and the abutting surfaces are flat surfaces. The rotating buckle body 61 abuts against the elastic locking component 7 through the abutting portion 64 to prevent the rotating buckle body 61 from reversing and avoid the user forcibly disassembling the front connector 4 roughly.

[0034] Preferably, the elastic locking assembly 7 includes a torsion spring 71 and a spring piece 72. One end of the torsion spring 71 is connected to the main board 3, and the other end of the torsion spring 71 is connected to the lower rotating buckle 6. A connection hole 20 is provided on the rotating buckle body 61, and the other end of the torsion spring 71 is inserted into the connection hole 20 to realize the connection with the lower rotating buckle 6. The spring piece 72 includes a spring piece body 721 and an elastic free end 722 integrally formed with the spring piece body 721. The shape of the spring piece body 721 is L-shaped, and one side thereof is fixedly connected to the main board 3. The elastic free end 722 is fixedly connected to one end of the spring piece body 721 close to the lower rotating buckle 6. When the current front connector 4 is inserted into the connection assembly, the elastic free end 722 abuts against the lower rotating buckle 6. When it is necessary to disassemble the front connector 4, use a screw to toggle the elastic free end 722 so that it no longer abuts against one side of the rotating buckle body 61. The elastic locking assembly 7 uses the elastic force of the torsion spring 71 and the spring piece 72 to realize the pluggable connection of the lower rotating buckle 6 in the front connector 4.

[0035] Optionally, the front connector 4 includes a connection bar 41 and two plug-in members 42. The plug-in members 42 are sequentially distributed along the length direction of the connection bar 41, and each plug-in member 42 is fixedly connected to the same side of the connection bar 41. A socket 10 for inserting the lower rotating buckle 6 is provided on any one of the plug-in members 42. The two plug-in members 42 respectively correspond to the upper rotating buckle 5 and the lower rotating buckle 6, and the plug-in member 42 is in positioning cooperation with the installation position 16. In this embodiment, sockets 10 are provided on both of the two plug-in members 42. One socket 10 is for inserting the upper rotating buckle 5, and the other socket 10 is for inserting the lower rotating buckle 6. The two sockets 10 are arranged oppositely to realize the detachable connection between the front connector 4 and the connection assembly.

[0036] The connection device of the drawer panel provided by the embodiment of the present invention further includes an adjusting bolt 13. An adjusting through hole 14 is provided on the plug-in member 42, and the adjusting bolt 13 is screwed into the adjusting through hole 14. By adjusting the depth of the adjusting bolt 13 inserted into the adjusting through hole 14, the end of the adjusting bolt 13 is made to press against the main board 3 to the left or right, so that the plug-in member 42 moves left and right in the installation position 16, so as to realize the left and right movement of the front connector 4 relative to the main board 3, and the left and right positions of the drawer panel 1 and the drawer side plate 2 can be finely adjusted.

[0037] In addition, the main board 3 is mounted on the drawer side plate 2 through the fixing plate 9. The fixing plate 9 is mounted on the drawer side plate 2. The main board 3 is connected to the fixing plate 9 through the up-and-down adjusting member 23, and the main board 3 can move up and down relative to the fixing plate 9 to achieve fine adjustment of the main board 3 in the height direction. The fixing plate 9 is in an L shape, and one side of it is fixedly connected to the drawer side plate 2. The fixing plate 9 is provided with mounting holes 11, and the main board 3 is provided with elongated through holes 12. The length direction of the elongated through holes 12 is perpendicular to the length direction of the main board 3. The up-and-down adjusting member 23 passes through the elongated through holes 12 and is inserted into the mounting holes 11 to realize the connection between the main board 3 and the fixing plate 9. In this embodiment, the up-and-down adjusting member 23 is an eccentric screw or an eccentric rivet, and the mounting hole 11 is a screw hole that is in threaded cooperation with the up-and-down adjusting member 23. The user can realize the up-and-down fine adjustment of the main board 3 relative to the fixing plate 9 by adjusting the position of the up-and-down adjusting member 23 in the elongated through holes 12. The fixing plate 9 is provided with assembly holes 21, and the main board 3 is provided with avoidance holes 22 arranged along the length direction of the main board 3. The bottom end of the fastening screw 19 passes through the avoidance holes 22 and is screwed into the assembly holes 21. When the up-and-down adjusting member 23 is adjusted up and down, the position of the fastening screw 19 in the avoidance holes 22 can be finely adjusted to avoid the up-and-down adjusting member 23. The top end of the fastening screw 19 protrudes from the main board 3 and is hooked and connected to the rotating ring 63 to realize the sliding connection of the rotating ring 63 on the main board 3.

[0038] To solve the same technical problem, an embodiment of the present invention further provides a drawer, which includes a drawer front panel 1, drawer side plates 2, and a connecting device for the drawer front panel as described in any of the above solutions. The front connecting code 4 of the connecting device for the drawer front panel is fixedly connected to the drawer front panel 1. The main board 3 is connected to the drawer side plates 2. The main board 3 is connected to the drawer side plates 2 through the fixing plate 9 and can be finely adjusted up, down, left, and right relative to the drawer side plates 2. The drawer is relatively tall, and can realize the connection and separation of the drawer front panel 1 and the drawer side plates 2, facilitating the user to install and disassemble the drawer.

[0039] The working process of the present invention is as follows: the connecting strip 41 of the front connector 4 is fixedly mounted on the drawer panel 1, and two plug-in components 42 are fixedly connected to the side of the connecting strip 41 away from the drawer panel 1. The fixing plate 9 is fixedly connected to the drawer side panel 2, and the main board 3 is connected to the fixing plate 9 in an adjustable manner up and down through the up and down adjusting components 23. The user can adjust the up and down adjusting components 23 to achieve the relative position of the drawer panel 1 and the drawer side panel 2 in the vertical direction. The plug-in component 42 of the front connector 4 is movably connected with an adjusting bolt 13. By screwing the adjusting bolt 13, the adjusting bolt 13 can push the main board 3 to achieve the left-right displacement adjustment of the front connector 4 and the main board 3. When installing the drawer, insert the front connection code 4 into the installation position 16, and the end of the plug-in card 42 away from the connecting strip 41 pushes the first rotating plate 51, so that it drives the second rotating plate 52 to rotate, and the rotating rod rotates accordingly, the turn button body 61 of the lower turn button 6 rotates, the rotating ring 63 slides, and the clamping part 17 is inserted into the socket 10 of the plug-in card 42 corresponding to its position and positioned to match it. At the same time, the second turn button 52 is also inserted into the socket 10 of the plug-in card 42 corresponding to its position after rotation, so that the front connection code 4 is inserted into the connecting assembly. At this time, one side of the turn button body 61 abuts against the spring 72. When the drawer panel 1 needs to be disassembled, first move the elastic free end 722 of the spring 72 so that it does not contact the turn button body 61, insert a cross screwdriver into the cross-shaped hole 18, and rotate the turn button body 61 so that the clamping part 17 leaves the socket 10. The knob body 61 rotates, driving the rotating rod to rotate, the second rotating plate 52 rotates and leaves the socket 10, and the first rotating plate 51 rotates and hits the plug-in card 42, so that the front connector 4 pops out. If the front connector 4 is forcibly disassembled, the knob body 61 cannot rotate in the opposite direction due to the obstruction of the spring sheet 72, and the upper knob 5 and the lower knob 6 cannot leave the socket 10, and the front connector 4 will not pop out and will still be locked on the main board 3.

[0040] In summary, the embodiment of the present invention provides a connecting device for a drawer panel and a drawer, which is a heightened version, and two buckles, an upper buckle and a lower buckle, are provided on the main board, and the two are connected by a connecting rod. When any buckle rotates, the other buckle can be driven to rotate accordingly, and the lower buckle is pluggably connected to the front connection code. The elastic locking component is used to abut the lower buckle to prevent the lower buckle from rotating. When the front connection code is inserted into the connecting component, the front connection code hits the upper buckle, and the connecting rod and the lower buckle rotate accordingly. The lower buckle is inserted into the front connection code and abuts with the elastic locking component, so that the front connection code is fastened in the connecting component, and the drawer panel is connected to the drawer side plate. When disassembling the front connection code, the elastic locking component must be toggled first so that it does not abut against the lower buckle, and the lower buckle is driven to rotate, so that the connecting rod and the upper buckle rotate, and the front connection code is ejected. Otherwise, the elastic locking component is always abutted against the lower buckle, so that the lower buckle cannot rotate in the opposite direction. The connecting device of the drawer panel can realize the connection and separation between the drawer panel with a higher height and the drawer side panel, simplifying the operation of assembling and disassembling the drawer, and the connecting device of the drawer panel can be used repeatedly.

[0041] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can also be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
