Description

Dual fixed furniture plate body connecting piece

Technical Field

The utility model relates to an adapting unit of furniture plate body, a dual fixation formula furniture plate body connecting piece that the connection steadiness is strong specifically says so.

Background

The plate body connecting piece is a furniture plate body connecting part which is widely applied at present, and the fixed connection between the furniture plate bodies is realized mainly through the sequential connection effect of the eccentric wheel, the connecting rod and the connecting head which is pre-embedded in the plate body. The existing furniture board body connecting piece mainly comprises an expansion type connecting piece and a fastening type connecting piece, and the difference between the expansion type connecting piece and the fastening type connecting piece is that when a connecting rod is pulled by an eccentric wheel to generate displacement, an expansion type connecting head expands outwards, so that an inverted tooth on the outer side of the connecting head is clamped on the inner side of a board body; the fastening type connecting head does not generate shape change, and the plate body is fixed through the connection between the eccentric wheel and the connecting rod. However, the conventional expansion-type panel connection has two significant technical drawbacks. First, in the existing eccentric wheel structure, because the outer edge of the eccentric wheel is a circular arc, the outer edge of the eccentric wheel is easy to slip when being mounted on a plate body, and the eccentric wheel cannot be fixed on the plate body due to the slip, so that the connecting piece cannot be smoothly mounted. Secondly, the inner chute of the eccentric wheel is also a circular arc, and the expansion type connecting head has certain elastic restoring stress after being installed, and the stress can act on the inner chute of the eccentric wheel through the connecting rod. When the plate body is moved and shaken after being installed, the elastic restoring stress can cause the eccentric wheel to return and rotate on the installation position, thereby causing the phenomena of looseness and even shedding between the eccentric wheel and the connecting rod. Therefore, the existing board connector structure still needs to be further improved.

Disclosure of Invention

An object of the utility model is to overcome the not enough of prior art, provide a connect strong, the good dual fixed furniture plate body connecting piece of reliability of steadiness.

The combined structure can effectively improve the stability of the installation of the connecting piece and greatly improve the connection reliability after the installation of the board body is finished.

2. The utility model discloses an among the connecting piece, be equipped with protruding fixed station outside outer anti-skidding line on the surface of eccentric wheel, the opening direction and the eccentric wheel opposite direction of rotation of fixed station set up. When the eccentric wheel rotates, the side wall of the fixed table can generate a sliding guide effect on the inner wall of the plate body hole, so that the eccentric wheel can smoothly rotate to a specified position. When the eccentric wheel generates return rotation under the action of elastic restoring force of the connecting head, the opening of the fixing table can be clamped on the inner wall of the plate body hole to generate fixing action, so that the position stability of the eccentric wheel after installation is further improved, and the connection stability between the plate bodies is effectively improved.

3. The utility model discloses an among the connecting piece, the connecting rod is threaded connection with the connector, and is equipped with in the connector and connects the back taper guide slot that the screw groove communicates. This structure can ensure when the connecting rod rotation gets into the connector, the tip of connecting rod can strut the connector in the back taper guide slot, makes it form great extra long power to ensure the fixed of connector in the plate body, thereby improve the stability that the plate body is connected.

4. The utility model discloses an among the connecting piece, the surface of connector has the antiskid tooth, and the surface of connector is equipped with protruding fixed tooth outside the antiskid tooth. Firstly, the anti-skidding teeth can generate the fastening effect on the inner wall of the plate hole when the connector is outwards expanded, so that the connector is prevented from slipping out of the plate hole. Secondly, fixed tooth can further promote the power of cramping to plate body hole inner wall when the connector is flare-out to improve the positional stability of connector in the plate body hole.
