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] This embodiment includes a self-tapping part 1, a connecting rod 2, a wing 3 and a runner 4, which can be made of metal or PVC plastic.

[0041] see figure 1 and figure 2 , The self-tapping part 1 is composed of a threaded part 11, a shoulder 12, a transition part 13 and a locking part 14 in sequence, the threaded part 11 is provided with threads, the diameter of the shoulder 12 is larger than the diameter of the threaded part 11, and the transition part The diameter of 13 is smaller than that of the locking part 14, and the top end of the locking part 14 is provided with a cross groove 15 for use with a Phillips screwdriver.

[0042] see Figure 3-Figure 6 , The connecting rod 2 is sequentially composed of a connecting portion 21 , a shaft portion 22 and a tail portion 23 of an integral structure. The diameter of the connecting part 21 is the same as that of the shoulder 12, and the end of the connecting part 21 is provided with a concave locking groove 24, and the...

Embodiment 2

[0055] see Figure 31-Figure 34 , the wheel mounting portion 26 in this embodiment is a concave U-shaped groove, and the wheel lever 42 is rotatably located in the wheel mounting portion 26 . The rest of the structure and working process are the same as those in Embodiment 1, and will not be repeated here.

[0056] In addition to being used for connecting furniture parts, the present invention can also be used for connecting machine parts and other occasions that need to be connected, and is not limited to the specific embodiments of the present invention.

Abstract

The invention relates to a hidden connecting piece and a matched drill bit. The connecting piece comprises a self-tapping piece, a connecting rod, a side wing and a rotating wheel, the self-tapping piece is composed of a threaded part, a shoulder part, a transition part and a locking part, the connecting rod is composed of a connecting part, a rod body part and a tail part, the side wing is composed of a left side wing and a right side wing which are the same in size and shape, and a forked arc-shaped hook tongue is arranged at one end of the left side wing and one end of the right side wing and hooked on the supporting rod. Meanwhile, the left side wing and the right side wing tightly hold the rod body part of the connecting rod, the rotating wheel is composed of a wheel rod and two elliptical wheels, the left side wing and the right side wing jointly form a space capable of containing the elliptical wheels, and the elliptical wheels are located in the space; and the matched drill bit comprises a handle portion, a blade portion and a head portion, the blade portion is in a cone frustum shape, the diameter of the blade portion is gradually increased from the handle portion to the head portion, and the blade portion and the head portion are in transition connection in a gradually-shrinking manner. The connecting piece 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 invention relates to a connecting piece used for connecting furniture parts or machine parts, and a matching drill bit, in particular to a concealed connecting piece that can be completely hidden after installation and a matching drill bit used with the connecting piece.
