DETAILED DESCRIPTION

[0024] 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.

[0025] like Figure 1-Figure 4As shown: a stable sliding support hinge, including a long branch 1, a middle branch 2, a short branch 3, a pull rod 4 and a bottom groove 5 as hinged parts, the hinged parts are hingedly combined with each other by a plurality of solid rivets 7, the bottom groove 5 is a C-shaped bottom groove, and a slider assembly 6 is slidably arranged therein, the middle branch 2 and the short branch 3 each have one end hinged to the slider assembly 6, and the two hinge points are located on the left and right sides of the slider assembly 6, and a top screw 603 is provided in the middle of the slider assembly 6 to adjust the friction between itself and the bottom groove 5, and when the slider assembly 6 slides in the bottom groove 5, the stopping convex edge 501 formed at the end of the bottom groove 5 can stop it to limit its sliding range.

[0026] Furthermore, the hinge points of the hinged parts are formed with tapered holes, which are used to cooperate with the tail of the solid rivet. After riveting, the tail of the solid rivet will be compressed and deformed into a cone and fill the tapered hole. At this time, the top surface of the tapered tail will be flush with the hinged part 7. Figure 5 , Figure 6 As shown, the conventional hinge uses a hollow rivet whose tail will form a flange after riveting. In order to prevent the flange from interfering with the opening and closing of the hinge, the hinge is generally provided with a countersunk hole corresponding to the flange at the hinge. However, the overall thickness of the flange is relatively thin and the countersunk hole cannot be filled. The gap in the countersunk hole will make the riveted position of the hinge relatively weak in bearing capacity compared with other positions. The present design chooses to replace the hollow rivet with a solid rivet 7. The tail of the solid rivet 7 is squeezed and deformed during the riveting process, thereby completely filling the tapered hole of the hinge. At this time, the riveted position of the hinge has a similar or equivalent bearing capacity compared with other positions.

[0027] Furthermore, the above-mentioned slider assembly 6 is a cast-in structure, which includes an engineering plastic slider 601 directly in contact with the bottom surface of the bottom groove 5, and a stainless steel metal insert 602 cast on the top surface of the engineering plastic slider 601; this type of slider with a cast-in structure not only has the wear-resistant advantages of engineering plastics, but also can enhance the strength of the overall structure through the metal insert 602, is not easy to deform or break, and has a longer service life.

[0028] Furthermore, the engineering plastic slider 601 has a blind hole with a certain depth at a position matching the top screw 603, and the top screw 603 can squeeze the engineering plastic slider 601 downward at the blind hole; since the engineering plastic itself has a certain hardness and is not easy to be squeezed downward, by opening a blind hole at a suitable position, the thickness of the slider at that position can be appropriately reduced, making it easier for the top screw 601 to squeeze it to adjust the friction force.

[0029] Furthermore, a guide top angle 8 is riveted on the front end of the bottom groove 5, and a corresponding pull rod head 9 is provided at the head end of the pull rod 4; as shown in the figure, the head end of the pull rod 4 is V-shaped, and the pull rod head 9 is formed with a groove of matching shape and with a positioning protrusion 901. The head end of the pull rod 4 is installed in the groove of the pull rod head 9 through the cooperation of its own positioning hole 401 and the positioning protrusion 901, and is fixed as a whole with the help of rivets. When the two are combined, the top surfaces of the pull rod 4 and the pull rod head 9 will be flush with each other, and no obvious abruptness will be generated.

[0030] Furthermore, a boss 502 is stamped at the end of the bottom groove 5, and the boss 502 and the slider assembly 6 are both higher than the top edge of the bottom groove 5, so that when the corresponding hinge is hinged thereto, there will be no friction and wear with the top edge, and noise problems can also be avoided.

[0031] Furthermore, an annular gasket is additionally provided at each hinge point of the present design, and the annular gasket is used to compensate for the height difference existing when the hinge parts are assembled.

[0032] As mentioned above, for some overweight and oversized windows, each position of the hinge should have sufficient supporting force. In order to facilitate the purchase of materials, traditional hinges generally directly select conventional hollow rivets as the riveted parts of the hinge. Since the flange formed by riveting the hollow rivets cannot fill the countersunk holes of the hinges, the hinge positions of the hinges are relatively weak in supporting capacity compared with other positions. Therefore, such hinges are not completely suitable for the installation of overweight and oversized windows. This design uses solid rivets as the riveted parts of the hinges, and the tails of the rivets can be deformed after riveting to fill the tapered holes of the hinges, so that each position of the hinge has similar or equivalent supporting capacity, which can adapt to the installation requirements of the above-mentioned overweight and oversized windows.

[0033] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
