DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
To make it easier for our examiner to understand the technical characteristics, objective and performance of the invention, we use a preferred embodiment together with the attached drawings for the detailed description of the invention.
Referring to FIGS. 2 and 3, the present invention comprises a base 10, a pressing ring 20, a propping rod 30 and two pads 50. The base 10 is a cylindrical lump having a pressing portion 11 extended transversally and circularly from an end of the base 10. The pressing portion 11 includes at least one elastic flange 12 disposed around the internal circular surface of the pressing portion 11, an external screw thread 13 disposed on the external surface at another end of the base 10, and a circular groove 14 disposed inwardly on the pressing portion 11 and having a screw thread. The circular groove 14 is connected downward to a hemispherical socket 15, and the pressing ring 20 has an internal circular surface 21 with a screw thread secured onto the screw thread 13 outside the base 10. An end of the propping rod 30 has a spherical joint 31, and the other end of the propping rod 30 has a screw thread 32, and the spherical joint 31 is contained in the socket 15 and can be swayed slightly in a small angle. A locking ring 33 having an external screw thread is secured onto the circular groove 14 to latch the propping rod 30 and connect the propping rod 30 with the base 10.
Referring to FIGS. 4A and 4B, the glass curtain fixing device of the present invention clamps and supports a glass 40 having at least one through hole and mounted onto a scaffold (not shown in the figure), wherein the base 10 is connected to the through hole of the glass 40, and the pressing portion 11 is separated by a pad 50 and presses against a distal surface of the glass 40, and the flange 12 of the pressing portion 11 presses against the pad 50. The pressing ring 20 is also separated by a pad 50 and presses against another distal surface of the glass 40. The structure of the foregoing screw thread 21 is connected to the base 10, and the pressing ring 20 together with the top and bottom of the pressing portion 11 are used to clamp and press against the glass 40. Further, the screw thread 32 of the propping rod 30 of the present invention is secured to a joint (not shown in the figure) and connected to the scaffold.
To improve the waterproof effect, the pad 50 has an elastic flange 51 disposed around the surface of the glass 40, and the through hole between the base 10 and the glass 40 also includes a cushion 70 for providing a better connection, when the base 10 is installed onto the through hole. The flange 12, 51 of the invention can be made by an elastic rubber material for providing a better waterproof effect.
Referring to FIG. 5, the present invention can be used for a double-layer airtight glass 60 whose upper and lower layers are coupled with an aluminum alloy lump 64 and an airtight strip 66, and an internal space 62 is formed within the two layers of the airtight glass 60. The internal space 62 of the airtight glass 60 can be a vacuum or filled with a gas for isolating noises and absorbing ultraviolet rays, and thus it is necessary to maintain a good airtight effect. The fixing device of the invention can clamp the airtight glass 60 and mount the airtight glass 60 onto the scaffold without damaging the air-tightness.
In summation of the description above, the pressing portion 11 and the pressing ring 20 clamp and press the glass 40 or the airtight glass 60 tightly, and the elasticity and deformation of the flange 12 can form a sealed leak-resisting structure, and thus the present invention constitutes a glass curtain that can provide a good waterproof effect or can prevent the airtight glass 60 from leaking air, so as to meet the user requirements.
While the invention has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
