[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 6 , the present invention provides a technical solution:

[0034] A wear-resistant steel connector, comprising an angle iron connector body 1 and bolt holes 4 for bolt insertion at four corners of the angle iron connector body 1, a reinforcing plate 1 2 and a reinforcing plate 2 3 are symmetrically distributed on the front side of the angle iron connector body 1, the reinforcing plate 1 2 and the reinforcing plate 2 3 are of right-angle structure design, and a detachable connection structure is provided between the reinforcing plate 1 2, the reinforcing plate 2 3 and the angle iron connector body 1;

[0035] The detachable connection structure includes a slider 3 10 fixedly connected to the front end surface of the angle iron connector body 1 near the upper side and a slider 1 9 located on the front side of the upper end surface of the angle iron connector body 1, wherein the slider 1 9 and the slider 3 10 are parallel to each other and both have a T-shaped structure design;

[0036] The rear sides of the reinforcing plates 1 2 and 2 3 and the positions corresponding to the sliders 1 9 and 3 10 are provided with a slide groove 5 that matches the sliders 3 10 and 1 9 . The slide groove 5 on the adjacent surfaces of the adjacent reinforcing plates 1 2 and 2 3 is designed as an open structure, and a limiting clamp 7 is provided inside the slide groove 5 at a position corresponding to the bolt hole 4 .

[0037] A slider 2 8 is fixedly connected to the front corner of the angle iron connector body 1, and a slide groove 2 6 is opened on the rear side of the reinforcing plate 1 2 and the reinforcing plate 2 3 at a position corresponding to the slider 2 8. The slider 2 8 is slidably connected inside the slide groove 2 6, and both ends of the slide groove 2 6 are designed as an open structure.

[0038] By adopting the above technical solution, when working, first the main body 1 of the angle iron connector is aligned with the reserved installation hole position on the steel frame member to be reinforced, and then the bolt is inserted through the bolt hole 4 to preliminarily fix the main body 1 of the angle iron connector and the steel structure member, and then the fixing nut is screwed on one end of the bolt on the front side of the bolt hole 4 to fix the whole. When the nut and the bolt are installed, the reinforcing plate 1 2 and the reinforcing plate 2 3 are then taken out, and the slide groove 1 5 on one side of the adjacent surface of the reinforcing plate 1 2 and the reinforcing plate 2 3 is aligned with the slider 1 9 and the slider 3 10 at two locations on the main body 1 of the angle iron connector, and then the slider 2 8 is aligned with the slide groove 26, and then push the reinforcing plate 1 2 and the reinforcing plate 2 3 in the same direction on the angle iron connector body 1 until the adjacent surfaces of the two are fitted together, completing the bolt hole 4 and one end of the bolt in the bolt hole 4, and the nut is blocked, and the nut position corresponds to the slide groove 1 5. Therefore, when the reinforcing plate 1 2 and the reinforcing plate 2 3 are pushed to fit together, the nut is relatively displaced in the slide groove 1 5, and then corresponds to the limiting clamp 7 in the slide groove 1 5. At this time, the nut is clamped by the limiting clamp 7 to prevent the subsequent nut from loosening and at the same time shielding it to reduce rain erosion.

[0039] Specifically, the adjacent surfaces of the reinforcing plate 1 2 and the reinforcing plate 2 3 are provided with connecting members, and the reinforcing plate 1 2 and the reinforcing plate 2 3 are detachably connected and fixed by the connecting members, and the connecting members include two buckles 16 connected and fixed to the reinforcing plate 1 2 and the reinforcing plate 2 3, and the buckle 16 is designed with a right-angle structure at one end away from the reinforcing plate 1 2 and the reinforcing plate 2 3, and the right-angle ends of the two buckles 16 are designed oppositely, and the two buckles 16 are staggered in the upper and lower positions, and the adjacent surfaces of the reinforcing plate 1 2 and the reinforcing plate 2 3 are provided with plug-in grooves 18 at positions corresponding to the buckles 16, and the right-angle ends of the buckles 16 are plugged into the plug-in groove 18 through the opening of the plug-in groove 18, and the inside of the plug-in groove 18 and the corresponding positions of the right-angle ends of the buckles 16 are fixedly connected with right-angled blocks 17, and the right-angle ends of the buckles 16 match the right-angled blocks 17.

[0040] By adopting the above technical scheme, when the reinforcing plate 1 2 and the reinforcing plate 2 3 are pushed to fit together, the buckles 16 installed on the adjacent surfaces of the two are respectively inserted into the plug-in slot 18. When inserted into the plug-in slot 18, the buckle 16 contacts the block 17, and then under the action of the inclination angle of the contact surface of the two, the buckle 16 is actively squeezed by the block 17. The buckle 16 is made of elastic metal material and has the characteristics of elastic deformation. Then the buckle 16 and the block 17 are misaligned, and the right-angled vertical edges of the two are pressed against each other to be fixed, so that the reinforcing plate 1 2 and the reinforcing plate 2 3 are combined and fixed to prevent them from being separated from the angle iron connector body 1. In the process of the buckle 16 displacing inside the plug-in slot 18, it will actively squeeze the airbag 19 located in the plug-in slot 18, and the airbag 19 will be compressed. The internal air is transported to the expansion bag through the airway 15. The expansion bag expands and actively fills the gap between the reinforcing plate 1 2 and the reinforcing plate 2 and the angle iron connector body 1, further reducing the probability of rainwater entering and greatly improving the protection effect.

[0041] Specifically, a docking hole 13 connected to the plug-in slot 18 is provided at a position corresponding to the upper end surface of the reinforcing plate 23, and a docking hole 14 is provided at a position corresponding to the plug-in slot 18. An airbag 19 is provided between the plug-in slot 18 and the right-angle end of the buckle 16. An airway 15 connected to the airbag 19 is provided inside the reinforcing plate 12 and the reinforcing plate 23. Expansion bags are fixedly connected to the rear end surfaces of the reinforcing plate 12 and the reinforcing plate 23, and the expansion bags are connected to the airway 15.

[0042] By adopting the above technical solution, if it is necessary to disassemble the reinforcing plate 1 2 and the reinforcing plate 2 3 later, first use a screwdriver or other tool through the docking hole 13 and the docking hole 2 14 to squeeze the buckle 16 located in the plug-in slot 18 so that it does not contact the block 17, and then pull the reinforcing plate 2 3 outward.

[0043] Working principle: When working, first, the main body 1 of the angle iron connector is aligned with the reserved installation hole position on the steel frame member to be reinforced, and then the bolt is inserted through the bolt hole 4 to preliminarily fix the main body 1 of the angle iron connector to the steel structure member, and then the fixing nut is screwed on one end of the bolt on the front side of the bolt hole 4 to fix the whole. When the nut and the bolt are installed, then take the reinforcement plate 1 2 and the reinforcement plate 2 3, and match the slide groove 1 5 on one side of the adjacent surface of the reinforcement plate 1 2 and the reinforcement plate 2 3 with the slider 1 9 and the slider 3 10 at two places on the main body 1 of the angle iron connector, and then the slider 2 8 is aligned with the slide groove 2 6 Then, the reinforcing plate 1 2 and the reinforcing plate 2 3 are pushed in the same direction on the angle iron connector body 1 until the adjacent surfaces of the two are fitted together, and the bolt hole 4 and one end of the bolt in the bolt hole 4 are completed. The nut is shielded, and the position of the nut corresponds to the slide groove 1 5. Therefore, when the reinforcing plate 1 2 and the reinforcing plate 2 3 are pushed to fit together, the nut is relatively displaced in the slide groove 1 5, and then matches and corresponds to the limiting clamp 7 in the slide groove 1 5. At this time, the nut is held tightly by the limiting clamp 7 to prevent the subsequent nut from loosening and at the same time shield it to reduce the erosion of rainwater;

[0044] Secondly, when the reinforcing plate 1 2 and the reinforcing plate 2 3 are pushed to fit together, the buckles 16 installed on the adjacent surfaces of the two are respectively inserted into the plug-in slot 18. When inserted into the plug-in slot 18, the buckle 16 contacts the block 17. Then, under the action of the inclination angle of the contact surfaces of the two, the buckle 16 is actively squeezed by the block 17. The buckle 16 is made of elastic metal material and has the characteristics of elastic deformation. Then the buckle 16 and the block 17 are misaligned, and the right-angled vertical edges of the two are fixed to each other, so that the reinforcing plate 1 2 and the reinforcing plate 2 3 are combined and fixed to prevent them from being separated from the angle iron connector body 1. In the process of the buckle 16 moving inside the plug-in slot 18, it will actively squeeze the airbag 19 located in the plug-in slot 18. The airbag 19 is compressed, and the internal air is transported to the expansion bag through the airway 15. The expansion bag expands and actively fills the gap between the reinforcing plate 1 2 and the reinforcing plate 2 and the angle iron connector body 1, further reducing the probability of rainwater entering and greatly improving the protection effect.

[0045] If the reinforcing plate 1 2 and the reinforcing plate 2 3 need to be disassembled later, firstly, a screwdriver or other tool is used to pass through the docking hole 13 and the docking hole 2 14, squeeze the buckle 16 located in the plug-in slot 18 so that it does not contact the block 17, and then pull the reinforcing plate 2 3 outward.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
