Description

M279709 Fourth, the creation description [new type of structure is fine, the internal hinge group '[previous technology according to the system door is up, so that Lu Cheng design as long as the door, iron must be heavy, such as a chain structure installed in the hinge • the main body • Pieces, in boxes. The degree of visual consideration is sufficient (1) The technical field of the invention] The creative department is about an improved structure of a heavy-duty hinge, 'especially to make it simple to manufacture and assemble, and the collar pivot hole does not need to be thinned twice and no sleeve is required. Barrels and bearings, and the pivot can be thickened to increase the strength. The door is the main entrance of the building. The most commonly seen door is hinged on the side of the door, and then pivoted on the door frame. The door can be turned to generate a rotary switch as it is pushed in and out. The hinge used The group has a long history. For generally lighter doors, it can be screwed to the door frame when the hinge is fixed, but for special large-scale shaped doors, stainless steel doors, etc. Heavy hinges must be used in conjunction with special fixing methods to carry the door body for normal opening and closing. For example, 'China Patent Bulletin No. 5 6 6 4 6 3 A heavy hinge improvement' The heavy hinge is composed of a seat body and a hinge. The door frame is provided with a hinge insertion port on the side of the door frame for insertion. The combination is mainly characterized in that: a cutout proportional to the seat is provided on the door frame, and screw holes and perforations are provided on the inner surface of the cutout and the lower edge of the inherent welding welding piece for locking the seat body to the front of the door as described above Although there are many types of heavy hinges in the previous case and the conventional ones, they are combined with a heavy door body. The design is in addition to the thickness of the steel plate of the hinge itself, and the bearing must be filled in the hole of the pivot to facilitate load rotation

M279709? Creation instructions (2). For example, there are bumps on the side of the sixth figure, and the concave holes of the two blades of the pivot hole are often corresponding to the shaft. In addition to the cost increase of the other parts, the other will be reduced. Affect its disadvantages. The hinge's two convex pivot holes can be used for the shaft-mounted D-shaped sleeve. Its combination is more troublesome. Fortunately, the placement is narrowed as shown in the restriction. Relying on the force mouth, and 'Pivot combination strong #habited sleeve pivot = degree plus the inner diameter of the pivot hole for the manufacture of the pivot type, the overall diameter is also set to make the heavy load 孑 L, in the case of thin cutting, you need to fill in the shaft It must have the same effect on the ascending assembly meter. The inside of the butterfly needs to be filled into the cylinder. The outer part of the shrink structure and the sleeve are miscellaneous. The fifth figure is for the pivot mounting sleeve. The working purpose of the barrel and the shaft is shown as the largest. [Creation purpose] The main purpose of this creation is to design a structure that is simple to manufacture and easy to assemble. 2 heavy-duty hinges, which do not need to be thinned twice in the pivot hole of the collar, and do not require the interior. Add sleeves and bearings, and the pivot can be thickened to increase the strength of the hinge combination. In order to achieve the aforementioned purpose, an improved structure of a heavy-duty hinge designed in this work 'provides the pivotal connection of a special heavy-duty door leaf and the door frame, mainly including: a fixed butterfly' is formed by curling a metal plate, and its butterfly One end of the sheet is provided with a plurality of tooth-shaped cutouts, and the other end is directly sheet-metalized into a set of rings by a metal plate.

279 M279709 丨 Fourth, creation instructions (3) ~ \ Pivot hole; once the butterfly is rotated, the system is provided with a plurality of spacer lock collar pivot holes at one end; The inner part of the collar pivot hole passes through this, so that the collar pivot hole does not need two cylinders and bearings, and the assembly strength of the hinge is improved. It is formed by curling a metal plate, and its holes 'the other end is directly fixed by metal plates in fixed and rotating intervals, and; a pivot' is used to thin the aforementioned components in series, and the interior is not simple, and The pivot can also add the sheet metal on the butterfly to form two interactive butterflies, the thickness of which is connected; the thickness of the sleeve needs to be added to enhance the composition and the actuality of the drawings. [Embodiment]. In order to further understand this Creation The more specific embodiment of this creation is described below. As shown in the first to fourth figures, an improved structure designed by this creation provides a pivotal connection between the extra heavy door leaf and the door frame, including a fixed butterfly (1), which is rolled into a sheet (1 A plurality of tooth-shaped cutouts (1 1 are directly sheet-thrown from a metal plate into a set of annular pivot holes (12); a rotating butterfly (2) is formed by curling a metal plate on the lug (2). One end is provided with a plurality of spaced lock holes (2 1), and the metal plate is directly sheet-metalized into complementary collar pivot holes (2 2); a set of washers (3) are respectively pads fixed and rotated), and (2) the two are complementary The collar pivot holes (1 2), (2), and a pivot (4), the thickness of which is opposite to the other features of the collar pivot hole, the details of the embodiment of the heavy-duty hinge, its main package shape, and its butterfly), the other End, its butterfly 'but the other end by the disc (1 2) butt (12)

At the pivot _) and the other end 2) phase and one side can be (45 (41 After assembly, the ring pivot hole _ also does not need a single component to facilitate the fixation of the hole area for fixing 2) inner diameter to connect the aforementioned components in series; when applied, the thickness limit of the metal plate is between 0 · 1 to A fixed butterfly (1) of 0.7 cm can be a convex body moving butterfly (2) with a single pivot hole (1 2), and a concave body with two pivot holes (2 2) on both sides. 1 2) and (2 2) can be near-circular holes. In addition, please refer to the first and second figures. The pivot (4) can be provided with an enlarged end (41) during manufacture. The enlarged end (41) The space on the front section of (4) can be directly provided with spaced rolling teeth (40%), so that it can be squeezed tightly with the pivot hole (2 2) of the collar when the string is connected, and an inner concave ring is provided in the radial direction. Slot (4 3), and a screw hole (2 3), a locking fixing screw (2 4) on the side of the rotating butterfly (the pair of collar pivot holes (2 2)), or as shown in the third figure Also, recesses (4 4) are provided at both ends of the pivot (4) for a fastener) pair, and the The outer end of the fastener (4 5) is a swollen end), and the surface is directly provided with spaced rolling teeth (4 2), so that the pivot (4) can be positioned and fastened without dislodging. Please refer to the first to third figures to make the structure of the sleeves (12) and (2 2) need not be thinned twice during manufacturing, and the sleeves and bearings are added as usual, so it can effectively reduce the heavy The hinge elements and processing steps reduce costs and simplify manufacturing and assembly. The combination uses only the pivot (4) to run in series, and the washer (3) cushioned in the interval between the complementary sleeves (12) and (22). (1) and rotating butterfly (2) maintain good mutual pivoting
