Detailed Description

Example 1

As shown in fig. 1-4, the structure of the adjustable through passage of the present invention includes: a through passage body 2 and an adjustable connecting frame 1; the adjustable connection frame 1 comprises: the fixing frame 12, the adjusting frame 11, the connecting frame 13 and the U-shaped plate 14; the connecting frame 13 is arranged at one end of the adjusting frame 11, and the other end of the adjusting frame 11 is inserted into the inner side of the fixed frame 12; the top, the bottom and two sides of the adjusting frame 11 and the fixing frame 12 are respectively provided with screw holes which are linearly arranged along the central axis direction and are matched in position, the distance between the adjacent screw holes is equal, and the adjusting frame 11 and the fixing frame 12 are fixed through bolts and screw holes; the bottom and two sides of the fixed frame 12, the connecting frame 13 and the U-shaped plate 14 are provided with through pin holes 15, and the bolt 16 connects the fixed frame 12, the connecting frame 13 and the U-shaped plate 14 through the pin holes 15; link up and say that main part both ends are equipped with end frame 21, and end frame 21 passes through the bolt fastening with fixed frame 12 remote connection frame 13 one end, end frame 21 bottom and both sides be equipped with the slot 22 that pinhole 15 corresponds, bolt 16 inserts slot 22.

More specifically, the bolt 16 is a screw rod near the cap end thereof, the pin hole 15 of the connecting frame 13 is provided with internal threads, and the bolt and the pin hole are screwed and fixed; the improved bolt is characterized in that a section of screw rod is arranged near the head part of the bolt, the bolt can be fixed in the pin hole, and the head part of the bolt is provided with a straight line or cross line or hexagonal recess structure which is convenient to screw in.

More specifically, the thickness of the U-shaped plate 14 is such that the two sides and the bottom of the outer surface of the U-shaped plate 14 are flush with the fixing frame 12 when the U-shaped plate 14 is assembled.

More specifically, the U-shaped plate 14 has a thickness > 2cm; the design of the U-shaped plate 14 can enhance the bearing capacity, and prevent the adjusting frame 11 from being too thin and unable to bear the weight of a human body, and the U-shaped plate 14 in the scheme is a plurality of U-shaped plates 14 with the length equal to the screw pitch or U-shaped plates 14 customized according to the length to be adjusted.
