Abstract
The utility model relates to a built-in nut type connecting structure which comprises a square tube frame A (1), a square steel frame B (3), a nut (2), a single-end bolt (4) and a mask (5), wherein the square tube frame A (1) and the square steel frame B (3) are of hollow structures, the nut (2) is embedded in the square tube frame A (1) and is a round nut, the height of the nut (2) is equal to the width of the outline of the square tube frame A (1), a through hole (6) is formed in the side surface of the square steel frame B (3), the threaded end of the single-end bolt (4) penetrates through the through hole (6) and is matched and connected with the nut (2), the single-end bolt (4) is used for fixing the square steel frame B (3) on one side of the square tube frame A (1), and the mask (5) is arranged at the other side of the square tube frame A (1). The built-in nut type connecting structure has the advantages of safety and firmness in connection, disassembly and attractive appearance.
Description
Technical field
The utility model relates to the linkage structure of metal thin-wall closure member, particularly built-in nut formula linkage structure.
Background technique
During connection between existing adjacent two metal thin-wall closure members normally on the metal thin-wall part and the corresponding position of connected piece join and be drilled with through hole, then pass two metal thin-wall parts and connected piece with bolt, then with nut, it closely is connected and fixed.Two spanners for the linkage structure action need of this class, block respectively nuts and bolt and could realize fastening purpose, and operation is trouble, and head and the afterbody of nut, bolt all be exposed in air, both affected overall appearance, reduces again its working life.
The model utility content
The purpose of this utility model is to overcome the shortcoming of prior art, provide a kind of connect safety firmly, the built-in nut formula linkage structure of detachable and beautiful shape.
The purpose of this utility model is achieved through the following technical solutions: built-in nut formula linkage structure, it comprises square steel framework A, square steel framework B, nut, single ended bolt and illiteracy plate, square steel framework A and square steel framework B are hollow structure, and square steel framework A is embedded with nut; The side opening of square steel framework B is provided with through hole, and the threaded end of single ended bolt passes through hole and is connected with nut, and single ended bolt is fixed on square steel framework B the side of square steel framework A, and the opposite side of square steel framework A is provided with the illiteracy plate.
The profile width of the height of described nut and square steel framework A is little 1 millimeter.
Described nut is round nut.
The utlity model has following advantage:
1, it is upper that nut is fixed on square steel framework A, and bolt is through square steel framework B and coordinates with nut, connects safety firmly, need screw off bolt just separable square steel framework A and square steel framework B, easy accessibility.
2, cover the outside that plate covers square steel framework A and square steel framework B, see from the outside, after screw bolt and nut is hidden in covers backboard fully, beautiful shape.
The accompanying drawing explanation
Fig. 1 is assembly structure schematic diagram of the present utility model;
The structural representation that Fig. 2 is square steel framework A;
The structural representation that Fig. 3 is square steel framework B;
Fig. 4 is the sectional structure schematic diagram that nut is embedded in square steel framework A inside;
The structural representation that Fig. 5 is nut;
In figure: 1-square steel framework A, the 2-nut, 3-square steel framework B, the 4-bolt, 5-covers plate, 6-through hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As shown in figures 1 and 3, built-in nut formula linkage structure, it comprises square steel framework A1, square steel framework B3, nut 2, single ended bolt 4 and illiteracy plate 5, and square steel framework A1 and square steel framework B3 are hollow structure, and square steel framework A1 is embedded with nut 2; The side opening of square steel framework B3 is provided with through hole 6, and the threaded end of single ended bolt 4 passes through hole 6 and is connected with nut 2, and single ended bolt 4 is fixed on square steel framework B3 the side of square steel framework A1, and the opposite side of square steel framework A1 is provided with and covers plate 5.
As shown in Fig. 2, Fig. 4 and Fig. 5, nut 2 is round nut, and the height of nut 2 equates with the profile width of square steel framework A1, and nut 2 sinks to the inside of square steel framework A1 fully.
