Technical Field

The invention relates to a connecting part of a furniture board body, in particular to a hidden elastic furniture board body connecting part with high installation speed and strong connection stability.

Background

The plate body connecting piece is a furniture plate body connecting piece which is widely applied at present, the existing furniture plate body connecting piece mainly comprises an expansion type connecting piece and a fastening type connecting piece, when the expansion type connecting piece works, the connecting rod generates displacement under the pulling of the eccentric wheel, and the connecting head can expand outwards, so that the inverted tooth on the outer side of the connecting head is clamped on the inner side of the plate body. The structure of the traditional expansion type furniture board connecting piece has two major technical defects. First, when the existing expansion furniture board connecting piece is installed on the board body, the connecting piece needs to be pressed into the fixing hole of the board body by using a tool. However, due to the machining tolerance or dimension error of the fixing hole of the plate body, the connecting piece is very easy to rotate during the installation process, so that the eccentric wheel of the connecting piece cannot be aligned with the installation hole in the plate body, and the normal installation of the connecting piece is hindered. Secondly, the plate body connecting piece exerts pulling force on the connecting rod through the rotation of the eccentric wheel to realize the outward expansion of the connecting head. However, the eccentric wheel is arranged in the plate body, the phenomenon of mutual rotation can be generated between the eccentric wheel and the plate body, the eccentric wheel cannot be fully tensioned to the connecting rod in the installation process due to the rotation phenomenon, the connection between the eccentric wheel and the connecting rod is loosened, and the stability and the reliability of connection between the plate bodies are seriously affected. Therefore, the existing plate connecting piece structure still needs to be further improved.

Compared with the traditional furniture board connecting piece, the hidden elastic furniture board connecting piece has the advantages that:

1. the connecting piece of the invention adopts a matching structure of the built-in cam and the connecting rod. At first, the pre-assembly before the plate body installation can be realized with the cam to the connecting rod, and the user only need rotate the pivot on the cam and can stimulate the connecting rod and remove to make first outer buckle and the outer buckle of second outwards open simultaneously under the effect of first inflation portion and second inflation portion, and the chucking has promoted the joint strength of connecting piece between plate body A and plate body B by a wide margin in plate body A and plate body B respectively. Secondly, the cam has the characteristics of larger rotating top pressure and rotation prevention, and the structure can effectively prevent the situation that the connecting rod moves back due to accidental stress when the two plate bodies are assembled or after the two plate bodies are assembled, so that the stability and the reliability of the assembly of the two plate bodies are ensured.

2. In the connecting piece, the rotatable elastic cam component adopts a combined structure of the seat body, the cam and the elastic component, and the rotating shaft on the cam can also extend out of the shell to be matched and connected with the mounting hole on the plate body B. The structure can not only enable the cam to generate thrust to the base body when rotating, but also ensure the position stability of the rotating shaft on the cam. In addition, the pivot is connected on the mounting hole, can further provide the positioning action for the connecting piece on the plate body, makes to form dual fixed in the connecting piece plate body B, has promoted the stability after the plate body installation.

The assembling speed of the connecting piece can be improved by the combined installation of the shells, and the position stability of the front shell 14 and the rear shell 15 after the installation of the plate bodies can be improved by the two positioning parts at the two ends of the shells, so that the situation of displacement caused by the size error of the plate holes is avoided. Be equipped with first outer buckle 11 and the outer buckle 12 that opens of second on the casing, first outer buckle 11 and the outer buckle 12 that opens of second are located plate body A and plate body B respectively after the plate body is accomplished the installation. The connecting rod 2 is disposed in the housing, which is slidable back and forth in the housing, and the rotatable elastic cam assembly is disposed on the connecting rod 2. The connecting rod 2 is further fixed with a first expansion part 21 and a second expansion part 22, and the first expansion part 21 and the second expansion part 22 are respectively matched and connected with the first outward-opening buckle 11 and the second outward-opening buckle 12. Through the rotation of rotatable elasticity cam subassembly, connecting rod 2 removes in the casing, and first inflation portion 21 and second inflation portion 22 act on respectively and open on first outer buckle 11 and the second outer buckle 12 of opening, and first outer buckle 11 and the second outer buckle 12 of opening can the joint in plate body A and plate body B. Meanwhile, the outermost ends of the first outward-opening buckle 11 and the second outward-opening buckle 12 are respectively located at the connecting positions far away from the plate body A and the plate body B, so that the first outward-opening buckle 11 and the second outward-opening buckle 12 both have pulling force towards the connecting positions, and the plate body A and the plate body B are always tightly connected. In addition, a second positioning block 23 is fixed on the connecting rod 2, a second positioning cavity 24 is formed in the shell, and the second positioning cavity 24 can be matched and connected with the second positioning block 23.

In order to realize the normal operation of the rotatable elastic cam component, the structure mainly comprises a seat body 31, a rotating shaft 32 and a cam 33. The seat body 31 is located on the connecting rod 2, and the seat body and the connecting rod 2 can be processed by adopting an integrally forming process. The rotating shaft 32 is respectively connected to the front housing 14 and the rear housing 15 and passes through the seat 31, and the cam 33 is fixedly connected to the rotating shaft 32. The outer edge of the cam 33 is matched and connected with the inner cavity of the seat body 31, and the bottom of the cam 33 is provided with an elastic piece 34. The elastic member 34 can be selected from a spring, a spring plate, etc. according to actual requirements. The housing is further provided with a containing cavity 13 for containing the elastic element 34, and the elastic element 34 is well positioned. A first positioning block 35 is arranged below the cam 33, a first positioning cavity 36 is arranged in the shell, and the first positioning block 35 can be matched and connected with the first positioning block 35 in the process that the cam 33 is pressed down, so that the cam 33 is prevented from accidentally rotating in the installation process.
