Problems solved by technology

[0002] Most of the panel body connections of furniture on the market now use a three-in-one connector (also known as an eccentric connector) consisting of an eccentric wheel, a connecting rod and a connector embedded in the panel body. The nut of the eccentric wheel will definitely be exposed, which will seriously affect the appearance of the finished furniture. In order to improve it, you can only paste the corresponding stickers or cover on the exposed part according to the material of the furniture board to cover it, but this still destroys the appearance of the finished furniture. Sex, greatly reducing the grade of finished furniture, making it impossible for products to enter the high-end market
[0003] High-end furniture will choose to use hidden hardware connectors for assembly, such as crescent-shaped connectors, but the crescent-shaped connectors require the factory to be equipped with special slotting equipment, which is expensive to purchase and use. If the factory is equipped with this equipment There will be a lot of cost to upgrade the technology, and the cost of the crescent-shaped connector itself is also high, so it is not yet popular in the mass market

Embodiment 1

[0040] The present embodiment includes a self-tapping member 1, a connecting rod 2, a rotary wheel 3 and a soft rubber strip 4, wherein the self-tapping member 1, the connecting rod 2 and the rotor 3 may be made of metal or PVC plastic material and the like.

[0041] See Figure 1 and Figure 2 , the self-tapping member 1 is composed of a threaded part 11 of the integrated structure, the shoulder 12, the transition part 13 and the locking part 14, the thread part 11 is provided with a thread, the diameter of the shoulder 12 is greater than the diameter of the thread part 11, the diameter of the transition part 13 is less than the diameter of the locking part 14, and the top of the locking part 14 is provided with a cross groove 15 used with a Phillips screwdriver.

[0042] See Figure 7-Figure 12 , the wheel 3 is composed of a wheel rod 32 and two wheels 31, the wheel rod 32 is a positive hexagonal prismatic shape, the two wheels 31 are symmetrically mounted on both sides of the whe...

Embodiment 2

[0053] See Figure 28-Figure 31, the wheel mounting portion 25 in the present embodiment is a through hole, the wheel rod 32 may be rotated located within the rotor mounting portion 25. The remaining structure and working process is the same as In Example 1 and will not be repeated.

[0054] In addition to connecting furniture components, the present invention may also be used to connect machine parts and other occasions that need to be connected, not limited to specific embodiments of the present invention.

Abstract

The invention discloses a hidden connecting piece which can be completely hidden after being installed. The connecting piece comprises a self-tapping piece, a connecting rod and a rotating wheel, the rotating wheel is composed of a wheel rod and two wheel parts, and the two wheel parts are symmetrically located on the two sides of the wheel rod; the self-tapping piece is sequentially composed of a thread part, a shoulder part, a transition part and a locking part, and a cross groove is formed in the top end of the locking part. The connecting rod is sequentially composed of a connecting part, a rod body part and a tail part, the end part of the connecting part is provided with a concave locking groove, and the size and the shape of the locking groove are matched with those of the transition part and the locking part of the self-tapping piece; the rod body part is concaved between the connecting part and the tail part, and the rod body part, the connecting part and the tail part jointly form a space capable of accommodating the wheel part; a rotating wheel mounting part is arranged on the rod body part, the wheel rod is rotatably positioned in the rotating wheel mounting part, and the wheel part is positioned in the space; and the tail part is in a circular arch shape and is provided with two symmetrical inner concave cambered surfaces. The method has the advantages of being capable of achieving complete hiding, accurate in positioning, high in connection stability and low in production cost.

Description

Technical field [0001] The present invention relates to a connection for connecting furniture components or machine components, in particular a hidden connector that can be completely hidden after installation. Background [0002] Now the market furniture panel connection is mostly made of eccentric wheel, connecting rod and embedded in the board body of the connector composed of three-in-one connector (also known as eccentric connector), after its installation, the screw cap of the eccentric wheel located at the junction must be exposed, seriously affecting the beauty of the finished furniture product, in order to improve, it can only be based on the material of the furniture board body in the exposed place to paste the corresponding sticker or face cover for covering, but this still destroys the aesthetics of the finished furniture product, greatly reducing the grade of the finished furniture product, Make the product unable to enter the high-end market. [0003] High-end furn...
