[0028] Example:

[0029] See also Figure 1-4 A new type of combined wooden door frame includes a side frame 1 and a top frame 13, the side frame 1 and the top frame 13 are slidably connected, a fixing hole 12 is opened on one side of the side frame 1 and the top frame 13, the two fixing holes 12 are connected, an expansion sleeve 16 is slidably connected inside the fixing hole 12, a cavity 17 is opened inside the expansion sleeve 16, an expansion nail 2 is arranged inside the expansion sleeve 16, the outer wall of the expansion nail 2 is fitted with the inner wall of the cavity 17, a flow groove 22 and a storage groove 23 are opened inside the expansion sleeve 16, the flow groove 22 and the storage groove 23 are connected, and the storage groove 23 is connected to the cavity 17. In this solution, the outline of the expansion nail 2 is larger than the outline of the cavity 17. When the expansion nail 2 is inserted into the cavity 17, the user can use a rubber hammer to hammer the top of the expansion nail 2, so that the expansion nail 2 continuously squeezes the cavity 17, so that the expansion sleeve 16 expands, and the connection of the expansion sleeve 16 inside the fixing hole 12 is more stable.

[0030] See also Figure 1-4A No. 1 sealing paper 18 is adhered to the intersection of the storage groove 23 and the cavity 17, and a No. 2 sealing paper 19 is adhered to both ends of the flow groove 22. In this solution, the storage groove 23 and the flow groove 22 can be sealed by adhering the No. 1 sealing paper 18 and the No. 2 sealing paper 19 to each other.

[0031] See also Figure 1-4 Glue is stored inside the storage groove 23 and the flow groove 22. In this solution, the glue stored in the storage groove 23 and the flow groove 22 is used to make the connection between the expansion sleeve 16 and the fixing hole 12 more stable.

[0032] See also Figure 1-4 The bottom end of the expansion nail 2 is fixedly connected with a cone head 21, which is located inside the storage groove 23 and is slidably connected to the storage groove 23. In this solution, as the expansion nail 2 continues to move in the cavity 17, the cone head 21 will pierce the No. 1 sealing paper 18. Since the diameter above the cone head 21 is the same as the diameter of the inner wall of the storage groove 23, the glue inside the storage groove 23 and the flow groove 22 will be squeezed. After the glue is squeezed, the two No. 2 sealing papers 19 will be broken, and the glue will flow along the flow groove 22 to the fitting place between the expansion sleeve 16 and the inner wall of the fixing hole 12, making the connection between the expansion sleeve 16 and the fixing hole 12 more stable.

[0033] See also Figure 1-4 A countersunk hole 11 is provided on the top of the side frame 1, and a threaded hole 14 is provided on one side of the top frame 13. The countersunk hole 11 and the threaded hole 14 are connected. In this embodiment, the diameter of the bottom of the countersunk hole 11 is the same as that of the threaded hole 14.

[0034] See also Figure 1-4 The internal thread of the threaded hole 14 is connected with a bolt 15, and the nut of the bolt 15 is located inside the countersunk hole 11. In this solution, the bolt 15 is used to connect and tighten the top frame 13 and the side frame 1.

[0035] Working principle: If the user wants to install the side frame 1 and the top frame 13, first splice the side frame 1 and the top frame 13, then use the bolts 15 to fasten the side frame 1 and the top frame 13, then insert the expansion sleeve 16 into the fixing hole 12, and then use a rubber hammer to hammer the expansion nail 2 into the expansion sleeve 16. During this process, the outline of the expansion nail 2 is larger than the outline of the cavity 17. When the expansion nail 2 is inserted into the cavity 17, the expansion nail 2 continuously squeezes the cavity 17, causing the expansion sleeve 16 to expand, so that The connection of the expansion sleeve 16 inside the fixing hole 12 is more stable. As the expansion nail 2 continues to move in the cavity 17, the cone head 21 will pierce the No. 1 sealing paper 18. Since the diameter above the cone head 21 is the same as the diameter of the inner wall of the storage groove 23, the glue inside the storage groove 23 and the flow groove 22 will be squeezed. After the glue is squeezed, the two No. 2 sealing papers 19 will be broken, and the glue will flow along the flow groove 22 to the fitting place between the expansion sleeve 16 and the inner wall of the fixing hole 12, making the connection between the expansion sleeve 16 and the fixing hole 12 more stable.

[0036] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
