Description

Technical Field

[0001] This invention relates to a connector for quick connection of drawer panels. Background Technology

[0002] In the connection between the drawer side panel and the front panel, a connector is used to quickly connect the two panels. The existing connector has a problem: when the connector is in the unlocked state, the connector on the front panel side can be separated from the connector on the side panel. However, after the connector is separated, the connector cannot remain in the unlocked state; it automatically resets to the locked state. This means that when reinstalling the front panel, the connector needs to be re-engaged to the unlocked state before the connector on the front panel side can be inserted. This type of connector is too complex to operate, requiring user intervention to unlock it during both disassembly and installation, and requires further improvement. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a connector for quick connection of drawer panels.

[0004] A connector for quick connection of drawer panels designed for this purpose includes a first connector and a second connector. The first connector has at least one slot with a front opening, and the second connector has a connecting pin that can be inserted into the slot from front to back.

[0005] A locking plate is movably provided on the first connector, and a locking groove is provided on the locking plate corresponding to the slot. The locking plate can move up and down relative to the first connector to allow the connecting pin to enter the locking groove or disengage from the locking groove.

[0006] The first connector is equipped with a release mechanism that can move back and forth.

[0007] The first connector is rotatably provided with a rotating element, and the rotating element is provided with a driven post and a toggle element;

[0008] The locking plate is provided with a guide groove that gradually slopes downwards from back to front, and the driven column is movably inserted into the guide groove.

[0009] The actuating element is connected to the releasing element for transmission;

[0010] The first connector is connected to the locking plate by an elastic element, and the elastic element applies a downward force to the locking plate.

[0011] When the first connector and the second connector are unlocked and separated, the rotating element rotates from the first position to the second position, and the driven post cooperates with the guide groove to drive the locking plate to move upward, so that the connecting pin is unlocked and separated from the locking groove; under the rotation of the rotating element, the actuating member drives the releasing member to move forward relative to the first connector.

[0012] When the rotating element is in the second position, the connecting pin is completely separated from the locking groove, and the driven post cooperates with the guide groove to constrain the locking plate to move downward.

[0013] Preferably, the rotating element is a gear, and the first connecting member is movably provided with a drive rack that meshes with the rotating element.

[0014] Preferably, the release member is provided with a strip-shaped limiting groove, and the first connecting member is provided with a limiting post that is movably inserted into the strip-shaped limiting groove.

[0015] Preferably, the release member is provided with a linkage rod, and the linkage rod is provided with a mating notch on the side near the rotating element;

[0016] As the rotating element rotates, the actuating member can rotate into the mating notch to push the releasing member forward.

[0017] Preferably, when the rotating element is in the second position, the axis of the driven column is located in front of the reference plane or coincides with the reference plane;

[0018] The reference plane is parallel to the direction of movement of the locking plate and coincides with the rotation axis of the rotating element.

[0019] Compared with the prior art, in this invention, when the rotating element is in the second position, the connecting pin is completely separated from the locking groove, and the driven post and the guide groove cooperate to constrain the locking plate to move downward. In this solution, when the rotating element rotates to the second position, the connector enters the unlocked state. In this state, the second connecting member can move forward to move the connecting pin relative to the slot and separate it. Due to the cooperation of the driven post and the guide groove, the locking plate can be constrained to move downward. When the locking plate cannot move downward, it means that the connector cannot enter the locked state. That is, after the connecting pin separates from the slot, the connector will not automatically enter the locked state, so that when the panel is reinstalled, the connecting pin can be reinserted into the slot without manual operation of the connector, thereby further locking.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] See Figures 1-6 A connector for quick connection of drawer panels includes a first connector 10 and a second connector 30. The first connector 10 is provided with at least one slot 110 with a front opening, and the second connector 30 is provided with a connecting pin 310 that can be inserted into the slot 110 from front to back.

[0028] A locking plate 20 is movably disposed on the first connector 10. The locking plate 20 is provided with a locking groove 210 corresponding to the slot 110. The locking plate 20 can move up and down relative to the first connector 10 to allow the connecting pin 310 to enter the locking groove 210 or disengage from the locking groove 210.

[0029] The first connector 10 is provided with a release element 70 that can move back and forth.

[0030] A rotating element 40 is rotatably disposed on the first connecting member 10, and a driven post 410 and a toggle member 420 are disposed on the rotating element 40.

[0031] The locking plate 20 is provided with a guide groove 220 that is gradually inclined downward from back to front, and the driven post 410 is movably inserted into the guide groove 220.

[0032] The actuating element 420 is connected and driven by the releasing element 70;

[0033] The first connector 10 is connected to the locking plate 20 by an elastic element 50, and the elastic element 50 applies a downward force to the locking plate 20.

[0034] When the first connector 10 and the second connector 30 are unlocked and separated, the rotating element 40 rotates from the first position to the second position, and the driven post 410 cooperates with the guide groove 220 to drive the locking plate 20 to move upward, so that the connecting pin 310 is unlocked and separated from the locking groove 210; under the rotation of the rotating element 40, the actuating element 420 drives the releasing element 70 to move forward relative to the first connector 10.

[0035] When the rotating element 40 is in the second position, the connecting pin 310 is completely separated from the locking groove 210, and the driven post 410 cooperates with the guide groove 220 to constrain the locking plate 20 to move downward.

[0036] Based on the above embodiments, when the drive connector is unlocked, the drive rotating element 40 is rotated along the first direction, causing the rotating element 40 to rotate from the first position to the second position. During this process, the driven post 410 follows the rotating element 40, thereby driving the locking plate 20 to move upward through the cooperation of the driven post 410 and the guide groove 220, until the rotating element 40 rotates to the second position. Figure 1 As shown. When the rotating element 40 is in the second position, the connecting pin 310 is completely separated from the locking groove 210, and the connecting pin 310 can move forward relative to the slot 110 to separate the second connecting member 30 from the first connecting member 10, thereby separating the panel 90 from the side plate 80.

[0037] Furthermore, as the locking plate 20 moves upward, the elastic element 50 is compressed to store force.

[0038] The function of the release member 70 is that, during the rotation of the rotating element 40 from the first position to the second position along the first direction, the actuating member 420 is connected to the release member 70 for transmission, which pushes the release member 70 forward until the rotating element 40 moves to the second position. At this position, the release member 70 is limited by the limiting post 740 and cannot move forward further. In this state, the release member 70 is constrained and cannot move forward, and the rotating element 40 is also constrained by the release member 70 and cannot move further along the first direction. This allows the driven post 410 to cooperate with the guide groove 220 to constrain the locking plate 20 to move downward, thereby keeping the locking plate 20 in the unlocked position.

[0039] When the panel 90 is reassembled with the side panel 80, the second connector 30 and the connecting pin 310 are inserted into the first connector 10. During the insertion process, the connecting pin 310 is inserted into the slot. As the second connector 30 and the connecting pin 310 move backward, they will push the release member 70 to move backward. During the backward movement of the release member 70, it will push the toggle member 420 to drive the rotating element 40 to rotate in the opposite direction to the first direction. During this process, the rotating element 40 moves from the second position to the first position. When the rotating element 40 leaves the second position, the rotating element 40 is in a rotatable state. Under the groove-shaped cooperation of the guide groove 220, the elastic element 50 releases the stored force and drives the locking plate 20 to move downward. The downward movement of the locking plate 20 causes the locking groove 210 to be inserted and locked with the connecting pin 310.

[0040] See Figure 1 When the rotating element 40 is in the second position, the axis of the driven column 410 is located in front of the reference plane 101 or coincides with the reference plane 101; the moving direction of the reference plane 101 is parallel to that of the locking plate 20 and coincides with the rotation axis of the rotating element 40.

[0041] When the rotating element 40 is in the second position, the elastic element 50 is compressed and stores force. This stored force acts on the locking plate 20, which will drive the locking plate 20 to move downward and reset. However, due to the position of the driven post 410 and the groove shape of the guide groove 220, and because the rotating element 40 cannot continue to rotate in the second direction and cannot rotate in the opposite direction, the locking plate 20 is constrained and cannot move downward, thus keeping the locking plate 20 in the unlocked state.

[0042] Furthermore, such as Figure 1 As shown, the guide groove 220 is inclined from back to front and downward. The inclined setting is so that when the locking plate 20 is in the unlocked state, the driven post 410 is located at the front end of the guide groove 220. The inclined setting can prevent the driven post 410 from moving to the rear side, thereby preventing the rotating element 40 from rotating in the opposite direction of the first direction and preventing it from entering the locked state under the force of the elastic element 50.

[0043] See Figure 2 The rotating element 40 is a gear, and the first connector 10 is movably provided with a drive rack 60 that meshes with the rotating element 40. When the drive connector is in the unlocked state, the tool 100 pushes the drive rack 60 to move relative to the first connector 10, and the drive rack 60 drives the rotating element 40 to rotate during the movement.

[0044] See Figure 2The release member 70 is provided with a strip-shaped limiting groove 730, and the first connecting member 10 is provided with a limiting post 740 that is movably inserted into the strip-shaped limiting groove 730. The limiting post 740 cooperates with the strip-shaped limiting groove 730 to restrict the range of forward and backward movement of the release member 70. When the rotating element 40 rotates to the second position, the rear end of the strip-shaped limiting groove 730 abuts against the limiting post 740. At this time, the release member 70 cannot continue to move forward, and the rotating element 40 cannot continue to move in the first direction.

[0045] See Figure 3 and Figure 4 The release member 70 is provided with a linkage rod 710, and the linkage rod 710 is provided with a mating notch 720 on the side near the rotating element 40; as the actuating member 420 rotates with the rotating element 40, the actuating member 420 can rotate into the mating notch 720 to push the release member 70 forward.

[0046] When the rotating element 40 rotates, it drives the actuating element 420 to rotate, which in turn pushes the linkage rod 710 to move the release element 70 forward. When the second connecting member 30 pushes the release element 70 to move rearward, the linkage rod 710 pushes the actuating element 420 to rotate the rotating element 40 in the opposite direction of the first direction.

[0047] See Figure 5 Both slot 110 and connecting pin 310 are provided in two at intervals, one above the other.

[0048] Furthermore, the second connector 30 is provided with a connecting ear 300, and the connecting pin 310 is fixed to the connecting ear 300. The connecting ear 300 is composed of two connecting pieces, left and right, and the connecting pin 310 is fixedly connected to the connecting pieces.
