[0002] I-beams are I-shaped steel structural components. When long I-beams are needed, multiple I-beams need to be connected together by welding or screws. During the connection, it is necessary to ensure that the ends of the I-beams are aligned. The assembly process is quite complicated, so an I-beam connection component needs to be designed. Utility Model Content

[0005] Furthermore, rubber strips are equidistantly embedded in the plane of the wedge block, and the outer surface of the rubber strips is in close contact with the inner wall of the limiting groove, increasing the friction between the wedge block and the limiting groove.
[0006] Furthermore, guide grooves are provided on both sides of the inner surface of the I-beam, and the inner wall corners of the guide grooves are designed with arc chamfers. The guide grooves and the limiting grooves are located on the same axis, which facilitates the guidance during the insertion of the wedge block.
[0007] Furthermore, positioning strips are fixedly installed on the inner surface of the I-beams to guide and restrict the fixing blocks. When the two I-beams are aligned, the two ends of the fixing blocks are aligned with the two positioning strips respectively, which facilitates the guidance and restriction of the fixing blocks.
[0008] Furthermore, the top of the contact surface between the positioning strip and the fixing block is designed with an arc-shaped chamfer, which facilitates the insertion of the fixing block.
[0009] Furthermore, the outer surface of the fixing mechanism is coated with corrosion-resistant paint.
[0010] The technical effects and advantages of this utility model are as follows:
[0011] 1. This utility model adopts this design so that after the ends of the two I-beams are aligned, the fixing block is pressed into the ends of the two I-beams. During the pressing process, the wedge block is forced back into the installation cavity. After the fixing block is pressed into the inner surface of the I-beam, the compression spring returns to its original position, so that the wedge block passes through the limiting groove, completing the quick connection of the two I-beams.
[0012] 2. This utility model adopts this design so that when two I-beams are aligned, the fixing block is inserted between the positioning strips on the two I-beams. The positioning strips guide the insertion position of the fixing block, and the chamfered corner at the top of the positioning strips facilitates the insertion of the fixing block.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0019] Example 1: Refer to Figure 1-4This utility model provides an I-beam connecting assembly, including a device body 100, which includes an I-beam 110, and a fixing mechanism 200. The fixing mechanism 200 includes a fixing block 210, and mounting cavities 211 are provided on both the front and rear sides of the fixing block 210. There are two mounting cavities 211 on each side, symmetrically distributed along the central axis of the fixing block 210. A wedge block 212 is installed on the inner wall of the mounting cavity 211 by a compression spring. When the wedge block 212 is in the ejected state, it remains in the mounting cavity 211. The internal length is at least 3 cm. The insertion end of the wedge block 212 is designed with a bevel. Both sides of the I-beam 110 are provided with limiting grooves 214 that are adapted to the wedge block 212. Rubber strips 213 are equidistantly embedded in the plane of the wedge block 212, and the outer surface of the rubber strips 213 and the inner wall of the limiting grooves 214 are tightly fitted. Guide grooves 215 are provided on both sides of the inner surface of the I-beam 110. The inner corner of the guide groove 215 is designed with an arc chamfer. The guide grooves 215 and the limiting grooves 214 are located on the same axis.
[0020] The working principle of Embodiment 1 of this utility model is as follows: In use, two I-beams 110 are aligned, and then the fixing block 210 is inserted into the mating ends of the two I-beams 110. During the insertion process, the inclined surface of the wedge block 212 contacts the guide groove 215, so that the wedge block 212 is compressed by force and compresses the spring, and retracts into the interior of the mounting cavity 211. After the fixing block 210 is inserted into the interior of the I-beams 110, the compression spring returns to its original position, pushing the wedge block 212 out through the limiting groove 214 on the two I-beams 110, thus completing the quick connection of the two I-beams 110.
[0021] Example 2:
[0022] The difference between Embodiment 2 and Embodiment 1 is that: a positioning strip 216 is fixedly installed on the inner surface of the I-beam 110 to guide and restrict the fixing block 210. The top of the contact surface between the positioning strip 216 and the fixing block 210 is designed with an arc-shaped chamfer. The outer surface of the fixing mechanism 200 is sprayed with corrosion-resistant paint. When the two I-beams 110 are aligned, the fixing block 210 is inserted between the positioning strips 216 on the two I-beams 110. The positioning strip 216 guides the insertion position of the fixing block 210, and the arc-shaped chamfer at the top of the positioning strip 216 facilitates the insertion of the fixing block 210.
