DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawing.
Referring to FIGS. 3A, 3B and 3C for the detailed description of the present invention, a glass door hinge structure comprises a hinge base 1, an axial bolt 2, and a fixing base 3. The hinge base 1 has a clamping groove 11 at its middle and one of the surface of the hinge base 1 is a thickened surface 12, and the thickened surface 12 has a transversal screw hole 13 for installing and combining a protruding bolt 4, a long spring coil 5, and a rotating screw bolt 6, wherein both ends of the long spring coil 5 are clamped and coupled to a protruding center 41 of the protruding bolt 4 and an indent 61 of the rotating screw bolt 6, and an external screw thread 62 at the external surface of the rotating screw bolt 6 is screwed and connected to a transversal screw hole 13 in the hinge base 1 for adjusting the resilience of the long spring coil 5, and the screw hole 13 at its center position has a vertical internal hole for installing the axial bolt 2, and a sunken groove 21 is disposed on both upper sides of the axial bolt 2 for propping the protruding bolt 4 by the resilience of the long spring coil 5, and the bottom of the axial bolt 2 is fixed into a center hole 311 of a hole base 31 in the fixing base 3 that is situated and fixed to the ground, and the two long screw bolts 7 are screwed into long screw thread holes 32 of the hole base 31 in the fixing base 3 and in contact with two sunken surfaces 22 disposed on both left and right sides of the axial bolt 2.
If the two glass doors F are installed at the positions in the clamping groove 11 at the middle of the hinge base 1 (as shown in FIGS. 4A and 4B), the glass door F can be installed directly since it is not necessary to make any cutting on the glass door F, and thus the invention can overcome the shortcomings of the prior art that requires cutting gaps on the glass door F or damages the glass door F or increases the cost.
The two long screw bolts 7 are turned and fixed into the long screw thread holes 32 adjacent to the hole base 31 of the fixing base 3 on the ground, so as to push and press the axial bolt 2 or turn the axial bolt 2 outward (as shown in FIG. 6). As a result, the pressed axial bolt 3 is turned to change its angle and drive both edges of the glass door F to turn slightly, so as to adjust both edges of the glass door F linearly. Before the two long screw bolts 7 are in contact with the two sunken surfaces 22 on both lower left and right sides of the axial bolt 2, the two long screw bolts 7 are passed through the long screw thread holes 32 of the hole base 31 of the fixing base 3, and thus enhancing the screw connection of the long screw bolts 7.
Since the length of the long spring coil 5 installed to both sides of a transversal screw hole 13 of the hinge base 1 is increased by the protruding bolt 4 and the rotating screw bolt 6 on both sides of the long spring coil 5, its length is longer than that of a traditional long spring coil 5 (as shown in FIG. 5), and thus enhancing the resilience and achieving the effect of resuming the two glass doors F quickly to their closed position.
In summation of the above description, the present invention definitely achieves the expected objective and provides an improved structure to enhance the performance over the prior art. The invention further complies with the patent application requirements and is duly filed for the patent application.
