[0040] See also Figure 1-4 The utility model provides a technical solution: a multifunctional keel fixing member, comprising:

[0041] The expansion tube 1 is abutted against one end surface of the keel, and comprises a positioning tube and a plurality of arc-shaped expansion plates 12 arranged opposite to each other. A first screw hole 11 is provided on the inner side of the positioning tube, and an external thread 13 is provided on the outer side;

[0042] A bolt 2 is inserted from the other end surface of the keel and screwed into the first screw hole 11;

[0043] A nut 3, which is threadedly connected to the external thread 13;

[0044] The second screw hole 41 on the inner side of the large support plate 4 is screwed to the external thread 13;

[0045] The small support piece 5 has a first countersunk hole 51 on its inner side that abuts against the nut at the end of the bolt 2 or the end of the expansion tube 1;

[0046] The washer 6 has a second countersunk hole 62 on its inner side which is sleeved on the nut at the middle or end of the bolt 2 .

[0047] A first edge 42 is disposed on the outer side of the large support piece 4 , and the side surface of the first edge 42 abuts against the inner side wall of the keel.

[0048] The first edge 42 is a stepped structure, and the first edge 42 is fitted into the countersunk structure of the keel end surface.

[0049] The first countersunk hole 51 is an inwardly retracted stepped countersunk hole. The inner side of the first countersunk hole 51 abuts against the end of the bolt 2 , and the outer side of the first countersunk hole 51 abuts against the end of the expansion tube 1 .

[0050] A second edge 52 is arranged outside the small support piece 5. The second edge 52 is an annular wedge-shaped structure. The wide surface of the small support piece 5 abuts against the end surface of the keel, and the outer side of the second edge 52 abuts against the countersunk structure of the end surface of the keel.

[0051] The gaskets 6 are stacked and abutted on the end surface of the keel, and the second countersunk holes 62 are conical countersunk holes.

[0052] The second countersunk hole 62 has a sleeve opening 61 on the side, and the sleeve opening 61 is a trapezoidal cross-sectional structure corresponding to the nut at the end of the bolt 2. The setting of the sleeve opening 61 facilitates the shim 6 to be pressed into the bolt 2 laterally, so that the shims 6 thereon can be stacked, the depth of the fixing can be adjusted, and the assembly is convenient.

[0053] This keel fixing can adapt to the assembly requirements of 38 keels and 50 keels, and is suitable for the assembly of light and heavy surface materials. A variety of component combinations and keel assembly methods make its assembly and leveling methods diverse, the scope of use is wide, the installation efficiency is improved, and it has multifunctional characteristics.

[0054] See also Figure 5-8 When assembling a single keel with a wall or a plate, the multifunctional keel fixing piece can be assembled in two main ways: the fixing piece is inserted into the end face or the other end face of the keel recess, specifically: the expansion tube 1 is abutted against one end face of the keel, the bolt 2 is screwed into the first screw hole 11, and the nut 3 is screwed into the external thread 13 to achieve assembly positioning; for the use case where the side positioning of the keel is required to be higher, the large support piece 4 can be assembled on the inner side of the keel bayonet to achieve the internal support shaping assembly method, such as Figure 5 For the use of the keel end surface positioning requirements are higher, the large support piece 4 can be assembled in the keel end surface countersunk structure assembly method, such as Figure 5 As shown in the middle part of the assembly embodiment, the wide surface of the small support piece 5 abuts against the inner and / or outer end surface of the countersunk structure, and abuts against the nut at the end of the bolt 2 and / or the end of the expansion tube 1 to achieve the keel end surface shaping, such as Figure 5-6 8; for some usage situations where the depth of the fixing member is required, the gasket 6 can be used. The gasket 6 is stacked and sleeved on the bolt 2, the expansion tube 1 abuts against the outside of the gasket 6, and the bolt 2 is inserted into and positioned in the second countersunk hole 62 and screwed into the first screw hole 11 of the expansion tube 1 to achieve the depth adjustment of the fixing member, such as Figure 7 As shown in the assembly embodiment diagram.

[0055] This multifunctional keel fixing piece can also be used for the connection and positioning of the intersection of multi-layer horizontal and vertical keels. Fig. 9 The two layers of keels can be connected with notches facing or back to back. The two layers of keels can be reinforced by setting a single or multi-layer large support sheet 4 or a small support sheet 5 or a gasket 6 between the two layers of keels. The outer sides of the upper and lower keels are assembled and reinforced by setting the above three components according to actual needs. The positioning of the three components with the expansion tube can be achieved by abutting with the end face of the expansion tube or by abutting with the convex ring end face of the side of the expansion tube. When assembling a 50 keel with a countersunk structure, the large support sheet 4 should be horizontally assembled on the outer end face of the keel countersunk structure to ensure the stable positioning of the support sheet and the keel.

[0056] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
