Abstract
The invention relates to an elastic-friction rotational-positioning hinge, which passes through and is arranged on a backing-up screw through a spacer block, an elastic element, a hinge plate A, an elastic element, a hinge plate B, another elastic element, and another spacer block in turn; the hinge plate A is a bent plate at a right angle, wherein the central position of one side plate is provided with a hole of which the outer edge is provided with a stopper plate, and the other side plate is provided with a mounting hole; the hinge plate B is a bent plate at a right angle, wherein the central position of one side plate is provided with a hole of which the outer edge is provided with a stopper groove, and the other side plate is provided with a mounting hole; and the stopper plate is arranged in the stopper groove. The hinge has the characteristics of simple structure, good self-locking performance and convenient mounting, and damage prevention. In addition, the hinge can be widely used in industries such as household appliances, furniture, jewelry boxes, portable communication terminals and the like.
Description
Technical field
The present invention relates to a kind of hinge, particularly a kind of elastic-friction rotational-positioning hinge that makes object keep several angle or certain position.
Background technique
Many apparatus, electrical equipment, communicating terminal etc. all have both to have been needed to rotate, and needed frame connecting structure spare---the hinge fixed again, did not much have automatic locking positioning device, and mainly there is the problem of following aspect in existing band lock-bit function hinge:
1, conventional hinge is generally clamped rotatingshaft sheet and the clamping bolt that a slice is connected with moving support by two stationary axle sheets that are connected with fixed rack and is formed, fix with the method for bolton then, damage the screw thread (be commonly called as and lose tooth) of bolt during this hinge uses easily; And locating effect is poor, behind the clamping bolt, still occurs loosening easily repeatedly.
2, the self-latching hinge of common notebook use, when after opening the computer monitor several angle, adjusting display device, spring clip in the hinge means is opened under pressure, can make display device keep several angle, though this hinge has its advantage, but its complex structure make also complexity, and torque value is less.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of simple in structure, not fragile, a kind of elastic-friction rotational-positioning hinge that the lock-bit performance is good, easy for installation is provided.
The present invention finishes with following mode.
Elastic-friction rotational-positioning hinge is installed on the backing-up screw successively by first cushion block, first elastic element, hinge plate A, second elastic element, hinge plate B, the 3rd elastic element and second cushion block, and is tightened through nut; Hinge plate A is the plate of a rectangular bending, and wherein the side plate center position is porose, and there is spacing pulling the outer, and another side plate has mounting hole; Hinge plate B is the plate of a rectangular bending, and wherein the side plate center position is porose, and there is limited impression the outer, and another side plate has mounting hole; Limiting board is installed in the limited impression.
Can regulate the rotation elasticity of hinge plate B by the degree that screws of adjusting nut, binding nut is contained in the terminal of backing-up screw and near nut.
Hinge plate A and hinge plate B bending part are pressed with stiffening rib.
Hinge sleeve be set with or spinning on first cushion block and second cushion block.
First elastic element, second elastic element and the 3rd elastic element are belleville springs.
First elastic element, second elastic element and the 3rd elastic element are sheet rubbers.
First elastic element, second elastic element and the 3rd elastic element are plastic sheets.
The present invention is simple in structure, the lock-bit performance is good and easy for installation, not fragile, the rotation elasticity that can regulate hinge plate by the degree that screws or the elastic element of adjusting nut, also can regulate the angle of hinge plate B 5 around the rotation of backing-up screw axis by the aperture that changes the hinge plate B limited impression, this hinge can be widely used in industries such as household electrical appliances, furniture, jewellery case and portable communication terminal.

Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
Present embodiment first elastic element 4, second elastic element and the 3rd elastic element all adopt belleville spring, and every group is combined by two belleville springs.Elastic-friction rotational-positioning hinge is mainly constituted by hinge plate A 3 and hinge plate B 5, backing-up screw 1, two cushion blocks 2, three groups of belleville springs, nut 6, binding nut 7 and two hinge sleeves 8.First cushion block 2, belleville spring, hinge plate A 3 (by hole 12), belleville spring, hinge plate B 5 (by hole 13), belleville spring and second cushion block are installed on the backing-up screw 1 successively, and are tightened through nut 6; Hinge plate A 3 and hinge plate B 5 spaces are installed between three groups of belleville springs, because screwing of nut 6, first cushion block 2 and second cushion block push to belleville spring mutually, make belleville spring distortion and closely contact with hinge plate A 3 and hinge plate B 5, and mutual extrusion, if connect object and fixing with hinge plate A 3 by mounting hole 14 usefulness screws this moment, external force is pulled hinge plate B 5 and is connected and mounting article by mounting hole 14 usefulness screws, because the compressibility of belleville spring, hinge plate B 5 is rotated around the backing-up screw axis, but hinge plate B 5 lateral plates that have hinge plate A 3 lateral plates in hole 12 and have a hole 13 can produce strong elastic-friction with belleville spring 4, the frictional force that is produced can overcome the self gravitation that connects hinge plate B 5 objects, therefore, shed external force, connect hinge plate B 5 objects and still can be positioned on fixed position, reach hinge lock-bit effect.
Hinge plate A 3 of the present invention is plates of a rectangular bending, and wherein the side plate center position is porose 12, and there is limiting board 9 outer, and another side plate has mounting hole 14; Hinge plate B 5 is plates of a rectangular bending, and wherein the side plate center position is porose 13, and there is limited impression 10 outer, and another side plate has mounting hole 14; Limiting board 9 is installed in the limited impression 10, can limit the angle of swing of hinge plate B 5, can regulate the angle of hinge plate B 5 around the rotation of backing-up screw axis by the aperture that changes hinge plate B 5 limited impressions 10.
The present invention can regulate the rotation elasticity of hinge plate B 5 by the degree that screws of adjusting nut 6, and binding nut 7 can prevent that near gland nut 6 nut 6 is owing to the frequent use of elastic-friction rotational-positioning hinge is become flexible.
Hinge plate A 3 of the present invention and hinge plate B 5 bending parts are pressed with stiffening rib 11, can strengthen the intensity of fixed plate A 3, B5, and the size of also visual connection object or weight are selected the thickness of the material of manufacturing usefulness.
Two hinge sleeves 8 of the present invention be set with or spinning on first cushion block 2 and second cushion block, make external form of the present invention more attractive in appearance, material can be plastics or metal.
