Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose of the present invention, the following detailed description will be given with reference to the accompanying drawings and preferred embodiments in order to provide the best mode, structure, features and effects according to the present invention.

Referring to fig. 2 and 3, the novel door top shaft according to the first embodiment of the present invention includes an upper shaft sleeve 1, a lower shaft sleeve 2, and a pair of bearings 3 fixed in the upper shaft sleeve 1 and the lower shaft sleeve 2, wherein a shaft core 4 capable of moving between the upper shaft sleeve 1 and the lower shaft sleeve 2 and a return spring 5 located between the shaft core 4 and the bottom of the lower shaft sleeve 2 are disposed in the lower shaft sleeve 2, and a set screw 6 for fixing the shaft core 4 is disposed at one end of the shaft core 4 close to the return spring 5. The lower shaft sleeve 2 is provided with a first limit hole 21 and a second limit hole 22 corresponding to the set screw 6, when the shaft core 4 is fixed in the first limit hole 21, the upper shaft sleeve 1 and the lower shaft sleeve 2 are in a fixed state, and when the shaft core 4 is fixed in the second limit hole 22, the upper shaft sleeve 1 and the lower shaft sleeve 2 are in a separated state.

The bearing 3 is a needle bearing. The shaft core 4 can be accommodated in the bearing 3, and the shaft core 4 is provided with a through hole 41 corresponding to the set screw 6.

First spacing hole 21, the spacing hole 22 of second all are equipped with the internal thread, and holding screw 6 is equipped with the external screw thread that corresponds with the internal thread, and the one end of holding screw 6 external screw thread dorsad is equipped with interior hexagonal hole 61.

One side of the lower shaft sleeve 2, which is back to the first limiting hole 21 and the second limiting hole 22, is provided with a mounting hole 23 capable of accommodating part of the set screw 6.
