Description

Technical Field

[0001] The utility model relates to the technical field of C-shaped steel, in particular to a C-shaped steel with adjustable size. Background Art

[0002] C-shaped steel is automatically processed and formed by a C-shaped steel forming machine. The C-shaped steel forming machine can automatically complete the C-shaped steel forming process according to the given C-shaped steel size. C-shaped steel is widely used in purlins and wall beams of steel structure buildings. It can also be combined into lightweight roof trusses, brackets and other building components. In addition, it can also be used for columns, beams and arms in mechanical light industry manufacturing.

[0003] Most common C-shaped steels are cast in one piece. In actual use, their sizes are fixed, making it inconvenient to adjust them during installation and use. As a result, their installation and use requirements are narrow and they cannot be applied to installation and construction needs in different situations. Utility Model Content

[0004] In view of the deficiencies of the prior art, the present invention provides a size-adjustable C-shaped steel, which solves the problems raised in the background art.

[0005] Technical Solution

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a size-adjustable C-shaped steel, comprising two mounting members, wherein the bottom surface of the mounting member on the left side is provided with two clips, the right sides of the two clips are both clipped with clips, the right sides of the two clips are both fixedly connected to steel cables, the bottom end of the mounting member on the right side is rotatably connected to a winding wheel, and the other ends of the two ropes are both fixedly connected to the winding wheel;

[0007] Two sockets are provided on the left side of the mounting piece on the right, and two plug-in blocks are fixedly connected to the left side of the mounting piece on the left. The two plug-in blocks are plugged into the sockets adjacent to them. The inner walls of the two sockets are provided with a group of card slots distributed at equal distances. The outer surfaces of the two sockets are provided with two sliding grooves. Card blocks are slidably connected to the interior of the multiple sliding grooves, and the multiple card blocks are carded into the slots adjacent to them.

[0008] Furthermore, the outer surfaces of the multiple blocks are fixedly connected to springs, and the other ends of the multiple springs are fixedly connected to the sliding grooves close to them. By installing the springs, the deformation force of the springs can push the blocks into the slots and maintain contact with the slots, so that the two mounting parts can be stably connected.

[0009] Furthermore, slots are provided inside the two plug blocks, and the two slots are connected to the sliding slots adjacent to them. A rotating rod is rotatably connected between the two slots, and the front and rear ends of the rotating rod are fixedly connected to three-pronged wires. The two three-pronged wires are fixedly connected to the blocks adjacent to them, and the two three-pronged wires are located in the slots adjacent to them. When the rotating rod is rotated, the rotating rod can reel in the three-pronged wires, thereby pulling multiple blocks, thereby separating them from the slots, making it easier to adjust the gap between the two mounting parts.

[0010] Furthermore, the outer surface of the winding wheel is fixedly connected to a plurality of teeth distributed in a circular pattern, and the bottom surface of the mounting part located on the right is fixedly connected to an elastic limiting part, which contacts the teeth close to it. The cooperation between the mounting teeth and the elastic limiting part can limit the winding wheel, so that the steel cable can remain taut and can apply a binding force between the two mounting parts.

[0011] Furthermore, the bottom surface of the mounting member on the right side is rotatably connected to two auxiliary wheels, and both steel cables are in contact with the auxiliary wheels close to them. Installing the auxiliary wheels can assist in tightening the two steel cables and keep the steel cables in a vertical state.

[0012] Furthermore, the plurality of springs are all in a reset state, and the two steel cables are both in a taut state. The taut state of the steel cables can provide a binding force between the two mounting parts, so that the two can be stably connected.

[0013] Furthermore, a pull rope is fixedly connected to the outer surface of the rotating rod, and the pull rope is in a reeled state. The installed pull rope can drive the rotating rod to rotate when the pull rope is pulled, so that the user can rotate the rotating rod easily.

[0014] The beneficial effects of the present invention are:

[0015] 1. The size-adjustable C-shaped steel can pull the two mounting parts closer to each other through a rope by rotating the winding wheel, thereby adjusting the size between them, which is convenient for use according to different needs. The two mounting parts can be limited by the cooperation of the mounting block and the slot, so that the two mounting parts can remain stable, thereby improving the overall practicality.

[0016] 2. The size-adjustable C-shaped steel can be installed with a three-pronged wire, so that when the rotating rod is rotated, the rotating rod can reel in the three-pronged wire, thereby pulling multiple blocks and separating them from the card slots, making it easier to adjust the gap between the two mounting parts. The installed pull rope can drive the rotating rod to rotate when the pull rope is pulled, making it easier for the user to rotate the rotating rod. BRIEF DESCRIPTION OF THE DRAWINGS
