Problems solved by technology

The door hinge with hinge pin structure, after long-term use of the door, the pin shaft and pin hole are prone to wear and tear, and the gap gradually increases, resulting in door leaf displacement, which obviously brings unfavorable results for the use occasions that require high positioning of the door leaf and door frame. The door hinge of the heavy-duty door using the bearing structure has a complicated hinge structure, high processing and manufacturing costs, and high installation requirements. There will be superposition of friction between the hinge seats, resulting in inflexible opening and closing of the door leaf and a large force

Embodiment 1

[0026] See attached figure 1 And attached figure 2 , A spherical hinge seat used for opening and closing the door body of the present invention consists of a fixed hinge seat 1, a movable hinge seat 2, a steel ball 3, a compression spring 4, a flange plate 5, a screw 6, and a plug bolt.

[0027] Wherein, the fixed hinge base 1 and the movable hinge base 2 form a conjoined structure. On the connecting base plate 13 of the fixed hinge seat 1, a hinge sleeve is fixedly connected. The sleeves 12, 11 have perforations 11.1 of the same diameter and the same axis.

[0028] On the connecting bottom plate 22 of the movable hinge seat 2, there is fixedly connected an intermediate hinge sleeve 21, which is located between the lower hinge sleeve 11 and the upper hinge sleeve 12, and at the upper and lower ends of the middle hinge sleeve 21, the coaxial The set has a hemispherical notch 21.1.

[0029] Two identical steel balls 3 are respectively placed in the upper and lower hemispher...

Embodiment 2

[0033] See attached image 3 , as a modification, the difference between this embodiment and the first embodiment is that: on the upper and lower ends of the middle hinge sleeve 21, a conical notch 21.1 with an outward opening is provided on the coaxial line.

Embodiment 3

[0035] See attached Figure 4 , as a modification, the difference between the present embodiment and the second embodiment is that the compression spring 4 is replaced by a rubber pad 9 .

Abstract

A spherical hinged support for opening and closure of a door comprises a door frame, a door leaf, a movable hinged support body connected to the door leaf and a fixed hinged support body connected to the door frame, wherein the movable hinged support body is provided with a hinge sleeve, the fixed hinged support body is provided with a hinge sleeve, and the hinge sleeves are hinged to each other. The spherical hinged support for opening and closure of the door is characterized in that notches are formed in the combination portions of the hinge sleeves correspondingly, and a steel ball is placed into each notch. The spherical hinged support for opening and closure of the door further comprises a pressure application structure for applying pressure to the steel balls. The spherical hinged support for opening and closure of the door is simple in structure and small in friction resistance, spherical surface abrasion is automatically compensated, and spherical surface is kept.

Description

technical field [0001] The invention relates to a door hinge, in particular to a spherical hinge seat for opening and closing a door body. Background technique [0002] The use of door is very extensive, and existing door hinge generally adopts the structure of hinge pin, or the hinge of heavy-duty door such as air defense door adopts bearing structure. The door hinge with hinge pin structure, after long-term use of the door, the pin shaft and pin hole are prone to wear and tear, and the gap gradually increases, resulting in door leaf displacement, which obviously brings unfavorable results for the use occasions that require high positioning of the door leaf and door frame. The door hinge of the heavy-duty door using the bearing structure has a complicated hinge structure, high processing and manufacturing costs, and high installation requirements. There will be superposition of friction between the hinge seats, resulting in inflexible opening and closing of the door leaf a...
