Abstract
The invention discloses a large-load positioning hinge device. The large-load positioning hinge device comprises a fixed hinge piece, a movable hinge piece, a wedge-shaped bolt, a bolt pull rod, a fixed hinge piece mounting plate, a movable hinge piece mounting rack and a hinge rotating shaft; a wedge-shaped groove matched with the wedge-shaped bolt is formed in the movable hinge piece; an equally wide open groove is formed by extending from the opening of the wedge-shaped groove; two wedged-shaped grooves matched with the wedge-shaped bolt are formed in the fixed hinge piece; when the wedge-shaped groove of the movable hinge piece is aligned to one wedge-shaped groove of the fixed hinge piece, the wedge-shaped groove surfaces of the fixed hinge piece and the movable hinge piece both are in tight fit with a face of the wedge-shaped bolt so that the movable hinge piece cannot move, and therefore, positioning is completed. According to the large-load positioning hinge device, a positioning gap is reduced by means of wedge-shaped fitted surfaces; meanwhile, under the acting force of a spring, the fitted surfaces can be closely fitted with each other even in the environments of vibrations and bumping; the movable hinge piece and the fixed hinge piece are prevented from displacing relative to each other, and shaking or impact phenomena are avoided.

Technical field
The present invention relates to hinge field, particularly a kind of heavy load locating hinge device.
Background technique
Hinge is used for connection two objects, and allows to rotate between the two.In actual applications, object usually needs fixed position after turning an angle.Such as, the operating table surface in small space or desktop need to pack up in a non-operative state, to reduce the space that it takies.And small space is many occurs in the environment such as vehicle-mounted or shipping container, have vibrations to affect with the mal-condition such as to jolt, in most cases operating table surface and desktop have certain weight.
Therefore, need certain load capacity, locating hinge device that reliability is high, above-mentioned service condition could be met.And the problem such as prior art ubiquity positioning load is less than normal, volume is too large.
Summary of the invention
The object of the present invention is to provide a kind of heavy load locating hinge device.
The technological scheme realizing the object of the invention is: a kind of heavy load locating hinge device, comprises fixed hinge sheet, hinges sheet, wedge shape dead bolt, dead bolt pull bar, fixed hinge sheet mounting plate, hinges sheet scaffold and hinge rotating shaft; Hinges sheet has 1 wedge slot coordinated with wedge shape dead bolt, this wedge slot opening is extended wide opening slot, fixed hinge sheet has 2 wedge slots coordinated with wedge shape dead bolt;
Fixed hinge sheet is fixedly installed on fixed hinge sheet mounting plate, and hinges sheet is fixedly installed on hinges sheet scaffold; Hinges sheet is connected with fixed hinge sheet by hinge rotating shaft, makes hinges sheet and hinges sheet scaffold can around hinge axis of rotation; Dead bolt pull bar is arranged on hinges sheet scaffold, and wedge shape dead bolt is connected with the bottom of dead bolt pull bar, can move along dead bolt pull bar axial direction; The axis of dead bolt pull bar is consistent with the wedge slot opening direction of hinges sheet, ensures that wedge shape dead bolt moves all the time in the wide opening slot of hinges sheet and wedge slot.
Compared with prior art, its remarkable result is in the present invention:
(1) the present invention adopts the mode of wedge shape faying surface to reduce positioning gap, under the force of a spring, even if in vibrations with the environment jolted, also can ensure faying surface laminating closely simultaneously, hinges and sheet fixed hinge sheet do not produce relative displacement, do not occur rocking or impact phenomenon;
(2) hinge plate of the present invention and dead bolt all adopt stainless steel to make, and can realize reliable location bearing in heavy load situation;
(3) the present invention adopts polytetrafluoroethylene bushing and packing ring in hinge rotating shaft place, effectively can ensure greasy property and reliability, the stability of hinge.

Embodiment
Composition graphs 1, Fig. 2, a kind of heavy load locating hinge device of the present invention, comprises fixed hinge sheet 1, hinges sheet 2, wedge shape dead bolt 3, dead bolt pull bar 4, fixed hinge sheet mounting plate 5, hinges sheet scaffold 6 and hinge rotating shaft; Hinges sheet 2 has 1 wedge slot coordinated with wedge shape dead bolt 3, this wedge slot opening is extended wide opening slot, fixed hinge sheet 1 has 2 wedge slots coordinated with wedge shape dead bolt 3;
Fixed hinge sheet 1 is fixedly installed on fixed hinge sheet mounting plate 5, and hinges sheet 2 is fixedly installed on hinges sheet scaffold 6; Hinges sheet 2 is connected with fixed hinge sheet 1 by hinge rotating shaft, makes hinges sheet 2 and hinges sheet scaffold 6 can around hinge axis of rotation; Dead bolt pull bar 4 is arranged on hinges sheet scaffold 6, and wedge shape dead bolt 3 is connected with the bottom of dead bolt pull bar 4, can move along dead bolt pull bar 4 axial direction; The axis of dead bolt pull bar 4 is consistent with the wedge slot opening direction of hinges sheet 2, ensures that wedge shape dead bolt 3 moves all the time in the wide opening slot of hinges sheet 2 and wedge slot.
Further, wedge shape dead bolt 3 is connected with dead bolt pull bar 4 by spring 13.
Further, fixed hinge sheet 1 is provided with stop screw 12, for the mobile range of restraint hinge plate 2.
Further, hinge rotating shaft is made up of steel shafts 7, lining 8 and packing ring 9, hinges sheet scaffold 6 is provided with axle head screw 11, axle head screw 11 cover has back-up ring 10, axle head screw 11 successively through back-up ring 10, hinges sheet 2 center hole, packing ring 9, fixed hinge sheet 1 center hole and lining 8, and embeds in steel shafts 7.
Described lining 8 and packing ring 9 are polytetrafluoroethylene bushing and polytetrafluoroethylene gasket, and teflon has the advantages such as high temperature resistant, corrosion-resistant, friction factor is extremely low, has self lubricity, effectively can ensure greasy property and reliability, the stability of hinge.
Further, described dead bolt pull bar 4 is arranged on hinges sheet scaffold 6 by upper and lower two draw-bar seats 14, draw-bar seat 14 is provided with the pilot hole of dead bolt pull bar 4, for limiting dead bolt pull bar 4DOF, it is made to move axially along pilot hole, pilot hole is consistent with the wedge slot opening direction of hinges sheet 2, ensure that wedge shape dead bolt moves all the time in the wide opening slot of hinges sheet 2 and wedge slot.
Further, fixed hinge sheet 1 and hinges sheet 2 are arranged on fixed hinge sheet mounting plate 5 and hinges sheet scaffold 6 respectively by screw 15.
In Fig. 3, hinge means is in and packs up positioning states.Under the active force of spring 13, wedge shape dead bolt 3 is pressed into fixed hinge plate 1 with the wedge slot of hinges sheet 2, and fit tightly, make fixed hinge sheet 1 relative with wedge shape dead bolt 3 irremovable, meanwhile, hinges sheet 2 and wedge shape dead bolt 3 are also relative irremovable, fit tightly effect namely by wedge shape dead bolt 3 and wedge slot, make hinges sheet 2 relative with fixed hinge sheet 1 irremovable, complete location.
When hinge needs upset, pull dead bolt pull bar 4, drive wedge shape dead bolt 3 to deviate from the wedge slot of fixed hinge sheet 1, make hinges sheet 2 around hinge axis of rotation, upset can be realized, as shown in Figure 4.In umklapp process, wide opening slot on hinges sheet 3 limits the space of wedge shape dead bolt 3, make it can only move in opening slot and along the opening direction of opening slot, draw-bar seat 14 has the pilot hole of dead bolt pull bar 4 simultaneously, limit the degrees of freedom of dead bolt pull bar 4, make it can only move axially along pilot hole, consistent with the movable direction of wedge shape dead bolt 3.
In hinge umklapp process, when hinges sheet 2 encounters deployed condition stop screw 12, produce spacing, now unclamp dead bolt pull bar 4, produce by spring 13 wedge slot that wedge shape dead bolt 3 to be pressed into fixed hinge sheet 1 by active force, as shown in Figure 5.
This device mostly is paired use, and when using in pairs, the structure of two ancillary equipments is symmetrical mutually.
