Description

Built-up joint

Technical field

The utility model relates to and connects two a kind of joints to two above objects.

Background technique

Existing built-up joint such as Fig. 1, shown in 2, mainly comprising one takes over institutes such as 20 at the multi-direction multidirectional connecting head 10 that all convexes with the hollow inserting column 11 of a square and some squares and forms, be equipped with two perforation 12 in each front of each inserting column 11, each inserting column 11 all can cooperate approximate＜shape snak link 30 that a surface convexes with two button columns 31 button knot and have the square of two perforation 21 to take over 20 with an example at two ends again to insert roped parties and close in advance, inserting the perforation 12 that makes inserting column 11 1 fronts behind the knot and square, to take over the perforation 21 of a side at 20 two ends relative, and the button column 31 on approximate＜shape snak link 30 surfaces can relative since then perforation outwards eject button knot square and takes over 20, and the continuous frame structure that is combined into.

Several square frame inner peripheral surface can cooperate a slice to have the skeleton frame plate 40 that square frame wall 41 and four limits extend flange 42 to place in its square frame in the framework that combination is finished, the perforation 43 in four corners of its skeleton frame plate 40 flanges 42, button column 31 by approximate＜shape snak link 30 of outside ejection props up linking (as shown in Figure 2), and the placement article can be provided.

Yet the frame structure that the above built-up joint is formed, skeleton frame plate 40 structures that it cooperated are just ejected and are connected on the frame structure of forming by approximate＜shape snak link 30 isometric button columns 31, not having any device, to be blocked knot fixing, thus its with frame structure between combine also insecure and drop out easily.

Summary of the invention

The purpose of this utility model provides a kind of framework that makes in conjunction with the built-up joint that firmly is difficult for dropping.

The purpose of this utility model is achieved in that built-up joint, it comprises: one in multi-direction multidirectional connecting head and the square adapter that all is convexly equipped with the hollow inserting column of a square, two perforation are all established in each front of each inserting column, each inserting column all can cooperate approximate＜shape snak link that a surface convexes with two button columns button knot and one side has the squares of two perforation to take over to insert roped parties and closes at two ends with more in advance, it is relative that the perforation in each front of inserting column and square are taken over the perforation of a side at two ends, and the button column on approximate＜shape snak link surface can relative since then perforation outwards ejects that button knot square is taken over and the continuous frame structure that is combined into; Square frame inner peripheral surface in the framework that button knot is finished can cooperate and has the skeleton frame plate that square frame wall and four limits extend flange and place in its square frame, and the placement article can be provided; It is characterized in that: in two button columns on this approximate＜shape snak link surface, grow for one of its outside and convex with the twice catching groove in both sides up and down in the head section, can buckle into the perforation in four corners of skeleton frame plate square frame wall and the skeleton frame plate is buckled knot fixing, drop out and avoid the skeleton frame plate to come off.

Above-mentioned design according to test, has reached and makes framework in conjunction with firmly and the effect that is difficult for dropping.

Embodiment

Shown in Fig. 3-5: the utility model comprises: one in multi-direction multidirectional connecting head 10 and the square adapter 20 that all is convexly equipped with the hollow inserting column 11 of a square, two perforation 12 are all established in each front of each inserting column 11, each inserting column 11 all can cooperate approximate＜shape snak link 30 that a surface convexes with two button columns button knot and one side has the square of two perforation 21 to take over 20 to insert roped parties and close at two ends with more in advance, it is relative that the perforation 12 in inserting column 11 each front and square are taken over the perforation 21 of a side at 20 two ends, and the perforation 21 that the button column on approximate＜shape snak link 30 surfaces can be relative is since then outwards ejected button knot squares and taken over 20 and the continuous frame structure that is combined into; Square frame inner peripheral surface in the framework that button knot is finished can cooperate and has the skeleton frame plate 40 that square frame wall 41 and four limits extend flange 42 and place in its square frame, and the placement article can be provided; It is characterized in that: in two button columns on this approximate＜shape snak link surface, one of its outside is longer, and convex with twice catching groove 33 in both sides up and down in the head section, can buckle into the perforation 43 in 41 4 corners of skeleton frame plate 40 square frame walls and skeleton frame plate 40 is buckled knot fixing, drop out and avoid the skeleton frame plate to come off.

As shown in Figure 3: the utility model comprises one and takes over 20 etc. at the multi-direction multidirectional connecting head 10 that all convexes with the hollow inserting column 11 of a square and some squares; Be equipped with two perforation 12 in each front of each inserting column 11, each inserting column 11 all can cooperate the three-dimensional structure diagram of an approximate＜shape snak link 30 as shown in Figure 4.

Approximate＜shape snak link structural perspective as shown in Figure 4, it convexes with a long button column 32 and a short button column 31 on the surface, there is the square of two perforation 21 to take over 20 with a side again behind the button knot in its inserting column 11 of can in advance packing into and inserts roped parties and close, wherein long button column 32 both sides and be concaved with catching groove 33 about the head section at two ends.The perforation 12 that makes inserting column 11 each front after inserting knot is relative with the perforation 21 that square is taken over 20 two ends, one side, and the button column 31,32 on approximate＜shape snak link 30 surfaces can be relative since then perforation 21 outwards eject button knot squares and take over 20, and the button group is combined into as shown in Figure 5 space framework composite structure continuously; Several square frame table faces in the framework that button knot is finished can cooperate some to have skeleton frame plate 40 that square frame wall 41 and four limits extend flange 42 and place in its square frame and the storing article can be provided again.

Shown in Fig. 5,6 partial enlarged drawing, cooperate as shown in Figure 3 again, approximate＜shape snak link 30 surperficial long and short two button columns 32,31, its refastenable perforation 43 of going into 41 4 corners of skeleton frame plate 40 square frame walls, and that the catching groove 33 of long button column 32 both sides can be detained knot to the perforation 43 of skeleton frame plate 40 is fixing, drop out firm combination and avoid the skeleton frame plate to come off.
