[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a door connecting upper shaft structure, including an upper shaft cover and a shaft sleeve, the inner cavity of the upper shaft cover is fixedly sleeved with a copper sleeve, the bottom of the shaft sleeve is integrally extended with a sliding groove, the inner cavity of the shaft sleeve is slidingly sleeved with a shaft column, and the surface of the shaft column is threadedly sleeved with a limit screw, and the limit screw is located in the inner cavity of the sliding groove, and a spring is arranged between one end of the shaft column and the inner cavity of the shaft sleeve.

[0006] Preferably, the surface of the limit screw and the inner cavity of the sliding groove match each other, and the limit screw is slidably sleeved in the inner cavity of the sliding groove.

[0007] Preferably, the surfaces of the upper shaft cover and the shaft sleeve are slidably sleeved with a fixing seat.

[0008] Preferably, a pressing sheet is provided at the bottom of the fixing seat.

[0009] Preferably, screw holes are provided at the bottoms of the upper shaft cover, the shaft sleeve, the fixing seat and the pressing plate, and the screw holes are flush with each other.

[0010] Preferably, fixing holes are provided on the sides of the upper shaft cover, the shaft sleeve and the fixing seat, and the fixing holes are flush with each other.

[0011] The utility model provides a door connecting upper shaft structure. Compared with the prior art, it has the following beneficial effects:

[0012] The door is connected with an upper shaft structure, which is installed on the upper shaft cover and the shaft sleeve through a fixing seat, and the pressing plate is installed at the bottom of the fixing seat. Finally, the upper shaft cover and the shaft sleeve are respectively installed on the door frame and the door profile, and are aligned with each other. The shaft column is pressed to retract the shaft column in the inner cavity of the shaft sleeve so that the shaft column is flush with the end of the shaft sleeve. Finally, when the door and the door frame are installed, the shaft column is loosened so that the shaft column is reset by the elastic force of the spring and inserted into the copper sleeve in the inner cavity of the upper shaft cover. At the same time, the limit screw will rest on the inner cavity of the sliding groove to limit the shaft column, thereby completing the installation. In this way, when the door is opened and closed, the shaft column can be rotated in the copper sleeve in the inner cavity of the upper shaft cover. The device can replace the traditional hinge, which is more portable in installation and has a stronger overall load-bearing capacity. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5The utility model provides a technical solution: a door connecting upper shaft structure, including an upper shaft cover 1 and a shaft sleeve 2, the inner cavity of the upper shaft cover 1 is fixedly sleeved with a copper sleeve 11, the bottom of the shaft sleeve 2 is integrally extended with a sliding groove 10, the inner cavity of the shaft sleeve 2 is slidably sleeved with a shaft column 6, and the surface of the shaft column 6 is threadedly sleeved with a limit screw 8, and the limit screw 8 is located in the inner cavity of the sliding groove 10, a spring 9 is arranged between one end of the shaft column 6 and the inner cavity of the shaft sleeve 2, the surface of the limit screw 8 and the inner cavity of the sliding groove 10 are mutually matched, and the limit screw The wire 8 is slidably sleeved in the inner cavity of the sliding groove 10, wherein the bottom of the upper shaft cover 1 and the shaft sleeve 2 are provided with a hollow cavity, and the sliding groove 10 is lower than the bottom of the shaft sleeve 2 and does not protrude, so the elastic force of the spring 9 drives the shaft column 6 to slide in the inner cavity of the shaft sleeve 2, so that the shaft column 6 is inserted into the copper sleeve 11 provided in the inner cavity of the upper shaft cover 1, wherein one end of the shaft column 6 is matched with the inner cavity of the copper sleeve 11, and when the shaft column 6 moves, its limit screw 8 will abut against the inner cavity of the sliding groove 10, thereby limiting the length of the shaft column 6.

[0021] A fixing seat 3 is slidably sleeved on the surfaces of the upper shaft cover 1 and the shaft sleeve 2 , and a pressing sheet 4 is arranged at the bottom of the fixing seat 3 .

[0022] The upper shaft cover 1, the shaft sleeve 2, the fixing seat 3 and the pressing plate 4 are provided with screw holes 7 at the bottom, and the screw holes 7 are flush with each other. The upper shaft cover 1, the shaft sleeve 2 and the fixing seat 3 are provided with fixing holes 5 on the sides, and the fixing holes 5 are flush with each other. By passing screws through the screw holes 7, the pressing plate 4 and the fixing seat 3 can be installed on the upper shaft cover 1 and the shaft sleeve 2, and can also be installed on the door profile.
