Description

Technical Field

[0001] The present invention relates to the technical field of household accessories, and particularly to a panel connection assembly and a connection device for a drawer having the panel connection assembly. Background Art

[0002] An assembled drawer is usually a one-sided open hexahedron structure composed of a front panel, a back panel, a bottom panel and two side panels. In the existing technology, the front panel and the two side panels are usually connected and fixed by screws. However, when assembling and disassembling the front panel and the side panels using screws, it takes a certain amount of time, which is not conducive to quick assembly or disassembly.

[0003] To overcome the deficiencies of the prior art, Chinese Patent No. CN201510678671.8 discloses a multi-latch connection structure for a drawer front panel and side panels, which includes fasteners and a panel connection assembly respectively installed on the front panel and the side panels. The fastener includes N plugs arranged side by side along the same straight line, and each plug is composed of two parallel insertion pieces with a gap between the two insertion pieces and a locking block provided in the gap; the panel connection assembly includes N slot bodies arranged side by side along the same straight line and a movable buckle plate with N card slots, and the movable buckle plate extends into each slot parallel to the extension direction of the slot. The movable buckle plate can also slide in the vertical direction and is provided with a return spring for resetting the movable buckle plate; the movable buckle plate cooperates with the gap between the two insertion pieces of the same plug, and N guiding bevels corresponding to the slots are formed on the side of the movable buckle plate facing the same direction as the slot entrance for the locking block to push the movable buckle plate out of the slot.

[0004] During the assembly process of the front panel and the side panels, first insert the fastener into the panel connection assembly. The movable buckle plate in the slot will be inserted into the gap between the two insertion pieces. When the locking block between the insertion pieces contacts the guiding bevel of the movable buckle plate, it will push the movable buckle plate to slide out of the slot, and at the same time, the fastener will continue to move forward; when the locking block reaches the end of the guiding bevel, the return spring will pull the movable buckle plate back, and at this time, the locking block will automatically snap into the card slot of the movable buckle plate, thereby locking the fastener in the card slot and realizing the connection between the front panel and the side panels.

[0005] When it is necessary to release the locking between the fastener and the panel connection assembly, just use a screwdriver to twist the cam. Driven by the cam adjusting part, the movable buckle plate will slide until the locking pin leaves the card slot, and then the fastener can be pulled out of the slot.

[0006] However, during the process of unlocking the connection between the fastener and the panel connection component, after using a screwdriver to twist the cam, it is necessary to use the screwdriver to maintain the position of the cam in order to ensure that the fastener can be pulled out from the slot. If the position of the cam is not maintained, the return spring will immediately pull the movable buckle plate back to its original position, preventing the fastener from being pulled out of the slot.

[0007] It can be seen that the unlocking operation of the multi-buckle connection structure of the front panel and the side panel of the drawer is relatively inconvenient and there is still room for further improvement. Summary of the Invention

[0035] A connecting device for a drawer, see Figures 1 to 8, which includes a front connector 1 and a panel connection component 2. The front connector 1 is used to be installed on the front panel of the drawer, and the panel connection component 2 is used to be installed on the side panel of the drawer. The front connector 1 is snap-connected to the panel connection component 2 to realize the fixed connection between the front panel and the side panel of the drawer.

[0036] See Figures 1 to 8 , the front connector 1 includes two plugs 11 composed of two mutually parallel inserts 111. Each plug 11 is arranged in the same straight line. In other embodiments, the number of plugs 11 can be N, where N is greater than or equal to two. There is a gap between the two inserts 111 on the same plug 11, and a round shaft-shaped locking block 112 with an axis perpendicular to the two inserts 111 is arranged in the gap.

[0037] See Figures 1 to 8 , the panel connection component 2 includes a first group of plates 21, a second group of plates 22, a third group of plates 23, a movable buckle plate 24, and a reset member 25. Among them, the first group of plates 21, the second group of plates 22, and the third group of plates 23 cooperate to form a slot 26 for the plug 11 to be inserted. In other embodiments, the number of slots 26 can be N. In this embodiment, the panel connection component 2 is hidden in the side panel of the drawer, and the entrance of its slot 26 is located on the side of the side panel of the drawer. The movable buckle plate 24 is located between the second group of plates 22 and the third group of plates 23. The movable buckle plate 24 slides between the second group of plates 22 and the third group of plates 23, and the sliding direction of the movable buckle plate 24 is perpendicular to the slot 26. In this embodiment, in order to realize the sliding of the movable buckle plate 24 between the second group of plates 22 and the third group of plates 23, a chute 241 is provided on the movable buckle plate 24, and the extending direction of the chute 241 is perpendicular to the extending direction of the slot 26. The second group of plates 22 and the third group of plates 23 are fixedly connected by a locking pin 231, and the locking pin 231 is stuck in the chute 241 of the movable buckle plate 24. A part of the movable buckle plate 24 extends into the slot 26 so that a part of the movable buckle plate 24 is inserted into the gap between the two inserts 111. A card slot 242 is formed on the movable buckle plate 24, and the card slot 242 corresponds to the slot 26 one by one. The card slot 242 is used for snap-connection with the locking block 112. The movable buckle plate 24 is formed with N guiding bevels 243 corresponding to the slot 26 one by one on the side facing the same direction as the entrance of the slot 26, and the ends of the guiding bevels 243 are the entrances of the card slots 242 respectively. One end of the reset member 25 is connected to the first group of plates 21 or the second group of plates 22 or the third group of plates 23, and the other end of the reset member 25 is connected to the movable buckle plate 24. In this embodiment, one end of the reset member 25 is fixed on the first group of plates 21, and the other end of the reset member 25 is connected to the movable buckle plate 24.

[0038] The locking process of the front connection code 1 and the panel connection component 2: First, insert the front connection code 1 into the panel connection component 2. The movable buckle plate 24 in the slot 26 will insert into the gap between the two inserts 111. When the clamping block 112 between the inserts 111 abuts against the guiding bevel 243 of the movable buckle plate 24, the clamping block 112 will push the movable buckle plate 24 to slide, so that the movable buckle plate 24 slides out of the slot 26, and at the same time, the front connection code 1 will continue to move forward; Then, when the clamping block 112 reaches the end of the guiding bevel 243, the reset member 25 will pull the movable buckle plate 24 back. At this time, the clamping block 112 will automatically snap into the clamping groove 242 of the movable buckle plate 24, thereby locking the front connection code 1 and the panel connection component 2 together, realizing the connection between the front panel of the drawer and the side panel of the drawer.

[0039] See Figures 1 to 8 , in order to unlock the front connection code 1 and the panel connection component 2, an arc-shaped groove 232 is provided on the third group of plates 23. The guiding direction of the arc-shaped groove 232 can be divided into two sub-directions. One sub-direction is perpendicular to the extension direction of the slot 26, and the other sub-direction is parallel to the extension direction of the slot 26. An activity groove 244 is provided on the movable buckle plate 24, and the guiding direction of the activity groove 244 is parallel to the extension direction of the slot 26. A driving member 234 is rotatably connected to the third group of plates 23 through a pin 233. A pin shaft 235 is detachably provided on the driving member 234. The pin shaft 235 penetrates through the third main board and the movable buckle plate 24. The pin shaft 235 slides in the arc-shaped groove 232, and the pin shaft 235 slides in the activity groove 244. Further, in order to facilitate pushing the driving member 234 to rotate, a cross groove 236 for inserting a screwdriver is also provided on the driving member 234, and the cross groove 236 is located between the pin 233 and the pin shaft 235.

[0040] The unlocking process of the front connection code 1 and the panel connection component 2: First, insert the screwdriver into the cross groove 236 of the driving member 234; Then, drive the screwdriver to rotate. Under the action of the screwdriver, the driving member 234 rotates around the pin 233; During the rotation of the driving member 234, the driving member 234 pulls the pin shaft 235 to move around the pin 233. The pin shaft 235 moves from the first end to the second end of the arc-shaped groove 232. The pin shaft 235 moves back and forth in the activity groove 244 and pushes the movable buckle plate 24 to slide, so that the movable buckle plate 24 slides out of the slot 26, thereby separating the movable buckle plate 24 from the clamping block 112 and realizing the unlocking of the front connection code 1 and the panel connection component 2.

[0041] Further, in order to maintain the separated state of the movable buckle plate 24 and the clamping block 112, see Figures 1 to 8, further comprising a slider 27, the slider 27 is slidably arranged on the third group of plates 23, the slider 27 is slidably arranged on the movable clamping plate 24, and the slider 27 is connected to the reset member 25. Specifically, a moving groove 237 is arranged on the third group of plates 23, a special-shaped groove 245 is arranged on the movable clamping plate 24, the slider 27 is slidably arranged in the moving groove 237, and the slider 27 moves in the special-shaped groove 245; the telescopic direction of the reset member 25 intersects with the sliding direction of the movable clamping plate 24, one end of the reset member 25 is connected to the first group of plates 21 or the second group of plates 22 or the third group of plates 23, and the other end of the reset member 25 is connected to the slider 27. When the movable clamping plate 24 and the clamping block 112 are in a separated state, the moving groove 237 exerts a first acting force a on the slider 27, the special-shaped groove 245 exerts a second acting force b on the slider 27, the reset member 25 exerts a third acting force c on the slider 27, and the resultant force among the first acting force a, the second acting force b, the third acting force c, and the self-gravity d of the slider 27 is zero. When the movable clamping plate 24 and the clamping block 112 are in a locked state, the special-shaped groove 245 exerts a fourth acting force e on the slider 27, the reset member 25 exerts a fifth acting force f on the slider 27, and the resultant force among the fourth acting force e, the fifth acting force f, and the self-gravity d of the slider 27 is zero.

[0042] Specifically, when the movable clamping plate 24 and the clamping block 112 are in a separated state, the first acting force a and the third acting force c are not parallel to each other, the second acting force b and the third acting force c are not parallel to each other, and the third acting force c and the self-gravity d are not parallel to each other; in this embodiment, the direction of the self-gravity d points vertically downward, the direction of the first acting force a points obliquely upward, the direction of the second acting force b is horizontally arranged, and the direction of the third acting force c points obliquely downward.

[0043] Specifically, when the movable clamping plate 24 and the clamping block 112 are in a locked state, the fourth acting force e and the fifth acting force f are not parallel to each other, and the fifth acting force f and the self-gravity d are not parallel to each other; in this embodiment, the direction of the self-gravity d points vertically downward, the direction of the fourth acting force e points obliquely upward, and the direction of the fifth acting force f points obliquely downward.

[0044] More specifically, in this embodiment, the moving groove 237 is an arc-shaped groove. When the movable buckle plate 24 and the clamping block 112 are in a separated state, the reset member 25 is located on the concave side of the moving groove 237. The special-shaped groove 245 has a first side 246 arranged vertically. When the movable buckle plate 24 and the clamping block 112 are in a separated state, the first side 246 abuts against the slider 27, and the first side 246 exerts a horizontally directed force on the slider 27. The special-shaped groove 245 further has a second side 247 that extends obliquely downward to the first side 246. The lower end of the second side 247 is connected to the upper end of the first side 246. When the movable buckle plate 24 and the clamping block 112 are in a locked state, the second side 247 abuts against the slider 27, and the second side 247 exerts an obliquely upward force on the slider 27.

[0045] The above-described embodiments merely represent several implementation manners of the present invention.
