[0021] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.
[0022] Please refer to Figures 1 - 3, the present utility model provides a technical solution: a concealed node connector for a wooden structure, including a back plate 1. On both sides of the surface of the back plate 1, bolt holes 2 are provided. At the bottom of the surface of the back plate 1, a plug-in component 3 is welded. There are eight bolt holes 2, and the eight bolt holes 2 are symmetrically distributed on both sides. The bolt holes 2 are back-convex counterbores;
[0023] Through the back-convex counterbores designed on the back plate 1, the bolt heads installed thereon can be completely sunk into the holes, hiding the bolt slots in the main components, avoiding the need to additionally reserve exposed bolt installation slots on the wooden components, greatly improving the appearance effect after the nodes are completed. Moreover, the back-convex back plate 1 increases the stress area of the nodes, effectively reducing the number of back bolts. Therefore, compared with traditional connectors, this connector is a more beautiful, efficient and safe connector. Through the plug-in component 3, precise alignment can be made more smooth and convenient through the locally reserved card slot design, and the on-site installation efficiency can be higher.
[0024] Refer to Figure 2 、 Figure 4 , the plug-in component 3 includes a steel plug plate 31 welded to the bottom of the surface of the back plate 1. On one side of the top surface of the steel plug plate 31, a notch is provided. On one side wall of the steel plug plate 31, a plurality of steel pin holes 32 are provided; in the middle of the top surface of the steel plug plate 31, a first pre-positioning card slot 33 is provided. At the position of the notch on the steel plug plate 31, a second pre-positioning card slot 34 is provided. The first pre-positioning card slot 33 and the second pre-positioning card slot 34 have the same specifications, and both are in a "U" shape;
[0025] Through the steel plug plate 31 in the plug-in component 3, it can not only be welded to the bottom of the surface of the back plate 1, but also provide a space for opening the notch, so that the steel plug plate 31 can be in an L shape, and thus can be better connected to wooden beams and wooden columns of various models and different angles. And on the basis of meeting the basic safety, the steel plug plate 31 makes precise alignment more smooth and convenient through the locally reserved "U"-shaped first pre-positioning card slot 33 and second pre-positioning card slot 34, and the on-site installation efficiency can be higher. Then, through a plurality of steel pin holes 32, steel pins can be conveniently installed, and further the connection stability between the steel plug plate 31 and wooden beams and wooden columns of various models and different angles can be strengthened.
[0026] Refer to Figure 2 、 Figure 4 , the outer side of the bottom end of the steel plug plate 31 is provided with an inclined chamfer, which can prevent the steel plug plate 31 from scratching the wooden structure.
[0027] Refer to Figure 2 、 Figure 4 , the thickness of the back plate 1 is the same as that of the steel plug plate 31, and both are made of carbon steel material, which can not only ensure the structural strength of the two, but also process the two with the same specification of materials.
[0028] During operation, the bolt heads installed on the backplane 1 can be completely sunk into the holes through the back-convex counterbores designed on the backplane 1, hiding the bolt slots within the main component and avoiding the need to additionally reserve exposed bolt installation slots on the wooden component. This significantly improves the appearance effect after the joint is completed. Moreover, the back-convex backplane 1 increases the stress-bearing area of the joint, effectively reducing the number of bolts on the back. Therefore, compared with traditional connectors, this connector is a more aesthetic, efficient, and safe connector. Through the insertion assembly 3, precise alignment can be made more smoothly and conveniently through the locally reserved slot design, making the on-site installation more efficient.
[0029] Through the steel insertion plate 31 in the insertion assembly 3, it can be welded to the bottom surface of the backplane 1 and also provide space for opening the notch, enabling the steel insertion plate 31 to be in an L shape. Thus, it can better connect wooden beams and wooden columns of various models and different angles. And on the basis of meeting the basic safety requirements, the steel insertion plate 31 makes precise alignment more smoothly and conveniently through the locally reserved first pre-positioning slot 33 and second pre-positioning slot 34 in a "U" shape, making the on-site installation more efficient. Then, through multiple steel pin holes 32, steel pins can be conveniently installed, further strengthening the connection stability between the steel insertion plate 31 and wooden beams and wooden columns of various models and different angles.
[0030] In summary, through the back-convex counterbores designed on the backplane 1, the bolt heads installed on it can be completely sunk into the holes, hiding the bolt slots within the main component and avoiding the need to additionally reserve exposed bolt installation slots on the wooden component. This significantly improves the appearance effect after the joint is completed. Moreover, the back-convex backplane 1 increases the stress-bearing area of the joint, effectively reducing the number of bolts on the back. Therefore, compared with traditional connectors, this connector is a more aesthetic, efficient, and safe connector. Through the insertion assembly 3, precise alignment can be made more smoothly and conveniently through the locally reserved slot design, making the on-site installation more efficient.
