Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

An adjustable back board fastener assembly for cabinet installation, as shown in fig. 1 to 3, at least comprises a fastener and an adjusting board 6. The adjusting plate 6 is provided with an adjusting groove 4 and a rotation fixing part 8.

The fastener comprises a connecting section 1 and a limiting end 3. One end of the connecting section 1 is fixedly connected with the limiting end 3. The connecting section 1 is provided with a groove 2 which axially surrounds a circle at the position adjacent to and connected with the limiting end 3. The radius of the connecting section 1 at the location of the recess 2 matches the groove width of the adjusting groove 4 in the adjusting plate 6. I.e. the groove portion of the coupling segment 1 can enter or snap into the adjustment groove 4.

Under the condition that the fasteners are clamped into the adjusting grooves 4 through the grooves 2 and fixed relative to each other, the rotary fixing parts 8 are used for carving grooves in the side plates in a rotary mode and embedding the side plates, so that the back plate and the side plates are fixed relative to each other.

So set up for the fastener can be through 4 adjusting positions of adjustment tank, and it is inseparabler to make to assemble between backplate and the curb plate, can not leave the gap. And after the back plate is buckled, if a gap exists between the back plate and the side plate, the adjustment can be carried out.

Preferably, the adjustment slot 4 comprises a straight section and a stop section 7. Straight line segments are provided at the edge of the adjustment plate 6 and form an opening allowing the fastener to be snapped in. The limiting section 7 is communicated with the straight line section and is provided with at least two limiting grooves 5. The fastener and the adjusting plate 6 are fixed relative to each other with the fastener caught in the stopper groove 5. The limiting groove 5 can be semicircular or rectangular. The retaining groove is sized to allow entry of the fastener. The limiting groove 5 can limit the transverse or longitudinal movement of the fastener along the side plate, so that the fastener and the adjusting plate 6 are fixed relative to each other. When the limiting groove 5 is semicircular, the radius of the limiting groove 5 is the same as that of the rod body of the groove part of the fastener.

If the included angle between the straight line segment and the limiting segment 7 is 90 degrees, the limiting groove can only limit the transverse or longitudinal movement of the fastener, and cannot simultaneously limit the transverse or longitudinal movement of the fastener. Preferably, the included angle between the straight line segment and the limiting segment 7 is more than 90 degrees, so that the limiting segment 7 is obliquely arranged relative to the straight line segment. In the case where the stopper section is inclined, the opening diameter of the semicircular stopper groove 5 is also inclined with respect to the straight line section. At this moment, the movement of the fastener in the longitudinal direction and the transverse direction can be limited, so that the fastener cannot move transversely or longitudinally in the limiting groove and can only move obliquely. Typically, the back and side panels are vertically connected such that the adjustment panel 6 moves in a lateral or longitudinal direction. Therefore, the inclined arrangement of the limiting section 7 makes the fastener difficult to actively move in the adjusting groove under the non-artificial condition.

Preferably, the rotation fixing part 8 includes at least the support column 11 and the first grooved part. The support column 11 is fixedly connected with the first slotted part. The fixed connection in the present invention means welding or integral connection. The rotation fixing portion 8 is provided on the adjustment plate 6 in a rotatable manner in one plane. That is, the supporting column 11 can rotate on the adjusting plate, so as to drive the rotation fixing part 8 to rotate. The rotatable manner is, for example, that the supporting column is hinged on the adjusting plate. Or the supporting column is provided with an annular groove, and the adjusting plate is provided with at least one hole. The radius of the supporting column is larger than that of the hole, and the radius of the position where the groove is arranged is smaller than that of the hole, so that the groove in the supporting column is clamped with the edge of the hole, the supporting column can only rotate in a plane and cannot move along the axial direction of the supporting column. So set up, guaranteed that rotation fixed part 8 does not influence the position of regulating plate when being connected with the curb plate, especially does not influence the removal of regulating plate in the third direction perpendicular to horizontal and longitudinal. The rotatable manner is not limited to the illustrated example, and mechanical coupling manners that are daily used may be used.

Preferably, the first slotted portion includes at least an initial segment 84, a ratchet segment 81, an expanding segment 82 and a slotted limiting segment 83, the initial segment 84 is a straight segment and is adjacent to the ratchet segment 81, and the ratchet segment 81 is an arc segment with ratchet teeth arranged on the edge. The expanding section 82 is arranged between the ratchet section 81 and the open slot limiting section 83 and is an arc section with smooth edge. The radius of the notched stopper section 83 is larger than that of the ratchet section 81 and the expanding section 82 to form a stopper protrusion for restricting the rotation of the rotation fixing section 8. Preferably, the ratchet section 81 and the expanding section 82 are arranged in such a manner that the radius is gradually increased. Radius here refers to the edge-to-center distance.

During rotation, the ratchet section 81, the expanding section 82 and the slotted limiting section 83 rotate towards the side plate in sequence, a plurality of ratchets of the ratchet section start to cut the plate, and a slot is formed in the plate. The flared section 82 fits into the plate slot along the cut-out slot to grip the plate and prevent it from loosening. The slot-restricting section 83 restricts the rotation of the rotation-fixing section 8 by the protruding edge and prevents the rotation of the rotation-fixing section 8, so that the rotation-fixing section 8 maintains the current rotation state.

Only the first grooved portion is provided, which has a drawback in that the first grooved portion of the rotation fixing portion 8 is caught in the plate in a sheet shape. When the board expands with heat and contracts with cold based on the ambient temperature, the first slot part and the slot may become loose. Furthermore, the first sheet-like grooved portion is easily inclined and separated from the plate. Based on this defect, the support post 11 is further provided with a second grooved portion 10. The second grooved section 10 is provided on the support column 11 in a plane-parallel manner with the first grooved section, and the first grooved section is provided at the top end of the support column 11. The structure of the second grooved portion 10 is completely the same as the structure of the first grooved portion, and the installation direction is also completely the same.

As shown in fig. 3, the second grooved portions are provided in a parallel manner so that the rotation fixing portion 8 is caught on the two grooves of the board through the two grooved portions. The position of the two slots on the plate is relatively unchanged, reducing the possibility of the rotation fixing part 8 tilting and also reducing the possibility of the rotation fixing part 8 disengaging from the plate.

Preferably, as shown in FIG. 2, the thickness of the dilating segments 82 gradually increases during rotation from a first blade end 821 adjacent to the ratchet tooth segment 81 to a second blade end 822 adjacent to the notch limiting segment 83. The advantage of the gradual increase in thickness of the expanding section 82 is that after the ratchet section 81 is slotted, the increased thickness of the expanding section 82 causes the expanding section to be pressed more tightly against the slot of the plate, which prevents the expanding section 82 from loosening and separating from the slotted slot.

Preferably, the center of the first grooved portion of the rotation fixing portion 8 is provided with an installation groove for screwing the back board buckle, and the installation groove is a cross groove, a cross groove or a star groove, so that an installer can conveniently drive the rotation fixing portion 8 to rotate through a tool such as a screwdriver.

As shown in fig. 4, at least one elastic sheet 12 is disposed on the side of the limiting section 7 not provided with the limiting groove 5. The elastic sheet is used for limiting the moving position of the fastener in the limiting groove 5. Preferably, the elastic sheet is a metal elastic sheet. The elastic sheet 12 is arranged along the axis of the limiting section, one end of the elastic sheet is fixed at one end of the limiting section 7, and the other end of the elastic sheet extends to the outlet of the straight line section of the adjusting groove. As shown in the figure, one end of the elastic sheet 12 can move and automatically reset in the limiting section based on pressure. The movable end of the elastic sheet 12 extends to most of the outlet of the straight line section, so that the fastener can only enter the limiting section by pressing the elastic sheet. The shrapnel can move the position based on the oppression of fastener in spacing section to allow the fastener to remove. So set up, the advantage lies in, when the fastener got into spacing section from the straightway, removed and got into spacing recess through oppression shell fragment. After the fastener enters the limiting groove, the moving space of the fastener is reduced. The existence of shell fragment makes the fastener can not freely remove at spacing section, has increased the resistance that the fastener freely removed.

The principle of the utility model is as follows:

when installed, the fasteners are mounted on the back plate. The installer mounts the adjustment plate on the side plate by turning the rotation fixing part 8. The fastener enters the adjusting groove and moves in the adjusting groove in a mode of pressing the elastic sheet until the back plate and the side plate move to proper positions. After the fastener enters the proper limiting groove, the elastic sheet resets and blocks the opening of the limiting groove. At this moment, the installer screws at least one screw 13 into the hole reserved by the adjusting plate, so that the screw enters the exit position of the straight line segment, and the screw is positioned at the bottom of the moving end of the elastic sheet, so that the moving end of the elastic sheet is positioned, the elastic sheet cannot move, and the fastener cannot move out of the limiting groove.
