Abstract
The utility model relates to a metal pipe frame connecting device, which is composed of a connection block (1), an expanded body (2), and wedge rods (3), wherein the connection block (1) is a block in different directions, and the block is formed by the connection of the wedge rods from 2 to 22 and a screw hole (4). One end of the expanded body (2) is a tubular body with one end provided with an expanded opening (5), and one end of the wedge rod is wedge-shaped body with one end provided with screw threads. The screw thread end of the wedge rod is screwed in the wedge rod connection screw hole (4) of the connection block (2). The utility model has the advantages of convenient disassembly and assembly. The metal pipe can be conveniently connected to form a frame or a shelf.
Description
Technical field
The utility model relates to the framework connection set
Background technique
At present, making of metal tube as during the framework of article rack, lamp box, billboard etc., generally adopting the mode of welding that metal tube is connected into framework or support body, framework or the support body made with the mode of welding are difficult to dismantle and reequip, and its making is wasted time and energy.
Technology contents
The purpose of this utility model provides and a kind ofly can easily metal tube be connected into framework or support body, and dismounting and reequip metal tube framework connecting head easily.
Technical solution of the present utility model is: it is made of contiguous block, expander and tapered bar, contiguous block is provided with the block that 2～22 tapered bars connect screw for different direction on it, expander is the tubular body that an end has the expansible opening, tapered bar is the wedge-like body that an end is provided with screw thread, tapered bar is through in the expander, and the tapered bar that the threaded end of tapered bar is screwed in contiguous block connects in the screw.
Technique effect of the present utility model is that it has and can easily metal tube be connected into framework or support body, and dismounting and reequip advantage easily.
