Detailed Description

The invention will be further described below with reference to the drawings and specific examples, but the embodiments of the invention are not limited thereto.

As shown in fig. 1 to 7, a hidden door shaft structure includes a door frame 1 and a frame profile 2, a door shaft 3 is disposed at each of four corner positions of the door frame 1, and the door shaft 3 is hidden and connected with the frame profile 2 through a rotating seat 4.

Preferably, the rotating seat 4 is provided with a countersunk head screw hole 5 and a door spindle insertion hole 6, and a hidden shaft sleeve 7 is arranged at a position, corresponding to the door spindle insertion hole 6, of one side of the rotating seat 4.

Preferably, the frame section bar 2 has four sides, and four side middle parts all are equipped with mounting groove 8, and the frame section bar 2 is used for connecting the arbitrary one side of door frame 1 and is equipped with hidden shaft hole 9 corresponding to the position of door-hinge spliced eye 6, and hidden axle sleeve 7 imbeds in hiding shaft hole 9.

Preferably, a limiting nut 10 is arranged in a mounting groove 8 of the frame section bar 2, which is used for connecting any side of the door frame 1, the rotating seat 4 penetrates through the countersunk head screw hole 5 through a flat machine screw 11 and is fixed with the limiting nut 10 in a threaded manner, and when the rotating seat 4 locks the flat machine screw 11, the hidden shaft sleeve 7 must be embedded into the hidden shaft hole 9.

Preferably, the door shaft 3 includes the door shaft shell 31, is equipped with the spring 32 in the door shaft shell 31, and a pivot 33 is worn to be equipped with by the one end of door shaft shell 31, and the one end of pivot 33 penetrates in the cavity of door shaft shell 31, and pushes down the spring 32, and the other end of pivot 33 inserts to hide to door shaft spliced eye 6, and the lateral part of door shaft shell 31 is equipped with open opening 34.
