Example 1:

referring to fig. 1 to 6, a furniture right-angle connecting fitting comprises a first connecting portion 10 and a second connecting portion 3, wherein the first connecting portion 10 and the second connecting portion 3 are in butt joint to form the connecting fitting, an open slot 15 is formed in the side surface of the first connecting portion 10, a U-shaped butt joint piece is arranged in the open slot 15, the U-shaped butt joint piece is composed of a sliding rod 9 and butt joint columns 6 arranged at two ends of the sliding rod 9, and the end heads of the butt joint columns 6 are provided with clamping blocks 2 of which the end surfaces are larger than the end surfaces of the butt joint columns; a rotating column 13 is arranged in the open slot 15, a bolt 14 and an incomplete gear 8 are respectively arranged at two sides of the rotating column 13, a rack 11 is arranged at one side of the sliding rod 9 close to the rotating column 13, and the incomplete gear 8 is meshed with the rack 11; one end of the rotating column 13 is provided with a wrench hole 12, and the end extends out of the opening groove 15 to be flush with the surface of the first connecting part 10; the 3 sides of second connecting portion are equipped with the lockhole 5 that supplies butt joint hole 16 that butt joint post 6 stretched into and supply spring bolt 14 to stretch into respectively, and 16 sides of butt joint hole are equipped with the joint hole 1 that is used for placing

joint piece

2, and 1 front portions in joint hole are unanimous with 6 sizes of butt joint post, and 1 rear portions in joint hole are unanimous with 2 sizes of joint piece.

In this embodiment, when two plates need to be spliced at a right angle, the end faces of the two plates are processed into inclined planes with 45-degree angle surfaces, then notches for installing the connecting parts are respectively cut at the corresponding positions of the 45-degree inclined planes of the two plates, a through hole leading to the notch needs to be drilled in the plate for installing the first connecting part 10, and the through hole points to the wrench wrenching hole 12 and is conveniently used for extending into the wrench control rotating column 13. The first connecting part 10 and the second connecting part 3 are respectively embedded in the notches of the two plates. Then two panels of butt joint make 45 degrees angle face laminating between them, butt joint post 6 stretches into in butt joint hole 16 this moment, utilizes the rotatory rotation post 13 of spanner, and spring bolt 14 rotates along with rotating post 13 and blocks in lockhole 5, and incomplete gear 8 rotates along with rotating post 13 and stirs slide bar 9 through rack 11, makes slide bar 9 drive joint piece 2 block in the joint hole 1. In the connection fittings, joint piece 2 and the cooperation of joint hole 1, spring bolt 14 and lockhole 5 for providing the connection holding power of vertical direction between the panel, then joint piece 2 and the cooperation of joint hole 1 provide the joint force of horizontal direction for panel is connected in addition, first connecting portion 10 and second connecting portion 3 break away from when avoiding the horizontal pulling. Therefore, the connection firmness of the two plates in the horizontal and vertical directions is ensured. When the plate connected by the connecting accessory is separated and disassembled, the lock tongue 14 can be separated from the lock hole 5, the clamping block 2 and the clamping hole 1 only by reversely rotating the rotating column 13, and the connecting and disassembling operation is convenient and fast, and the reusability is strong.

Besides being used as a right-angle connecting fitting, the connecting fitting can also be suitable for other connecting working scenes such as horizontal splicing of two plates, and has wide application and strong applicability.

Example 2:

joint piece

Furthermore, the end of the bolt 14 is provided with a clamping protrusion 17, and a clamping groove 4 matched with the clamping protrusion 17 is formed in the lock hole 5. After the clamping protrusion 17 is in butt joint with the clamping groove 4, the locking tongue 14 still has locking force when being stressed transversely, and the connecting firmness of the connecting piece is enhanced.

Further, first connecting portion 10 and second connecting portion 3 are semiellipse shape, and when cutting the notch that the system was used for placing connecting portion to panel, because current carpenter saw used the annular saw more, the notch that the annular saw fed the cutting and formed is just semiellipse shape. If the connecting part is in other shapes, the notch needs to be machined, and the machining process is increased. Therefore, the semi-elliptical first connecting part 10 and the semi-elliptical second connecting part 3 can be more conveniently installed, and the installation and processing time can be saved.

Furthermore, a plurality of limiting pins 7 are arranged in the open slot 15, one side of each limiting pin 7 is in contact with one side close to the corresponding rotating column 13, and the sliding rod 9 is limited and the supporting force borne by the sliding rod during horizontal pulling is enhanced.

Furthermore, the opening of the butt joint hole 16 is larger than the end face of the clamping block 2, so that the butt joint of the clamping block 2 and the butt joint hole 16 is more convenient.

The other parts of this embodiment are the same as embodiment 1, and are not described herein again.

The embodiment of the present invention is the above. The above embodiments and the specific parameters in the embodiments are only for the purpose of clearly showing the verification process of the utility model, and are not used to limit the patent protection scope of the utility model, the patent protection scope of the utility model is still subject to the claims, all the equivalent structural changes made by using the contents of the specification and the drawings of the utility model are included in the protection scope of the utility model.
