Abstract

The utility model discloses a stop hinge for turnover table top. The utility model is provided with a rotating shaft fixed on both ends of a middle position line of the opposite frames of a table top and a shaft hole on a supporting seat supporting the rotating shaft. The supporting seat is a right angle type wood board. A crossing bottom board of the right angle type wood board is fixed on a table support, and an upright board is also the supporting seat. A peripheral board of the shaft hole on the wood board is provided with two horizontal and upright convex steps which are mutually perpendicular. A block fixed on the frame of the table top rotates in a range of an angle with 90DEG of both convex steps. A stop pin bolt with a torsion spring fixed by screws is arranged on the crossing bottom board of the supporting seat. The pin bolt steadily and reliably supports the horizontal position of the table top. The hinge has the advantages of simple structure, flexible operation and firm stopping.

Description

The stop hinge of upset desktop

The utility model discloses a kind of stop hinge of the desktop that overturns, it belongs to the furniture field of mechanical technique.

The stop hinge of existing upset desktop generally all is to have rotating shaft, axle sleeve to connect admittedly on desktop meta bobbin.Its desktop can this axle be that the axle rotation is arbitrarily angled, and its hinge does not have stop component.For preventing the desktop upset, need add latch in addition and fix, its structure is attached most importance to assorted, and operation is also inconvenient.

The purpose of this utility model is the stop hinge that a kind of desktop that overturns will be provided.It is steadily firm when the desktop level is used, and during tipped upright, stablizes motionlessly, and its rotational angle is 90 degree.

Task of the present utility model has following technical scheme to finish, developed a kind of stop hinge of the desktop that overturns, it has: the rotating shaft that is fixed on the relative frame neutrality line two ends of desktop, this is installed in the bearing axis hole on the frame, the rectangular profile plate shape of this bearing, its horizontal base plate is fixed on the frame, its erect plate is bearing, except that the heart therein is provided with the axis hole, on the erect plate of this periphery, hole, also be provided with two mutually perpendicular levels and vertical boss rank, the block that is fixed on the relative frame of desktop two is that axle rotates 90 degree with the bearing pin in an angle of 90 degrees scope on these two boss rank then, on the horizontal base plate of bearing, be fixed with the stop pin of the band torsion spring of an inverted "L" shaped by screw, this pin is under the thrust of torsion spring, be inserted in the table frame below with its arc bolt point, rest the horizontal level of desktop.

Stop hinge of the present utility model, its advantage is: designed with the erect plate bearing on mutually perpendicular boss rank and the block that rotates in the boss order range, make desktop when level, be stuck on the horizontal ledge rank by block, simultaneously by the stop pin of band torsion spring below the block that under its torsion spring thrust its arc bolt point is inserted on the table frame, and make desktop all can not continue upset left, to the right and be fixed on level with rotating shaft.This hinge arrangement is simple, flexible overturning, fixing-stable.

Embodiment of the present utility model further describes as follows in conjunction with the accompanying drawings, as shown in the figure:

Fig. 1 is the front view of stop hinge when the desktop level.

Fig. 2 is the vertical view of stop hinge when the desktop level.

Fig. 3 is the right view of stop hinge when the desktop level.

Fig. 4 is the front view of stop hinge when the desktop erectility.

Fig. 5 is the vertical view of stop hinge when the desktop erectility.

Fig. 6 is the right view of stop hinge when the desktop erectility.

The stop hinge of a secondary upset desktop of making, it has the rotating shaft 1 that is fixed on the relative frame neutrality line two ends of desktop 13.This is installed in bearing 2 axis holes 3 on the frame.These bearing 2 rectangular profile plate shapes, its horizontal base plate 10 is fixed on the frame, and its erect plate is bearing 2, except that being provided with at the center the axis hole 3, also is provided with two mutually perpendicular levels and vertical boss rank 5,6 on the erect plate of these 3 peripheries, hole on it.Being fixed on 4 of link stoppers on 13 liang of relative frames of desktop is that axle rotates 90 degree with rotating shaft 1 in an angle of 90 degrees scope on these two boss rank 5,6.Between this block 4 and bearing 2 erect plates, be provided with packing ring at interval, turn over desktop 13 in order to baffle plate 4 and turn 90 degrees running flexibly.On the horizontal base plate 10 of bearing 2, be fixed with the stop pin 7 of the band torsion spring 11 of an inverted "L" shaped by screw 8.This pin 7 is inserted in the table frame below with its arc bolt point under the promotion of torsion spring 11, rest the horizontal level of desktop 13.The other end of this stop pin 7 is a handle 12, its desktop 13 from level when erectility overturns, (accompanying drawing is for clockwise rotating to the right) needs manual this handle 12, and plate is moving inwards with the stop pin, make the arc bolt point of this pin 7 outwards rotate an angle and make link stopper 4 on its sharp taken away from desktop 13 frames, desktop 13 promptly can rotating shaft 1 become erectility for the axial right side clockwise rotates 90 degree like this, this moment, block 4 just in time leaned against on the vertical boss rank 6, and desktop 13 can not be rotated further again.When desktop 13 by erectility (desktop 13 rotates counterclockwise left) when level is overturn, be located at block 4 on desktop 13 frames can be below stop pin 7 arc bolt point little by little outwards extrude the stop pin 7 of this band torsion spring 11.In case when desktop 13 was up to the standard the position, block 4 just in time broke away from the arc bolt point of stop pin 7, and this bolt point is overspend the horizontal level of holder desktop 13 turning round of torsion spring 11 just in time inserted block 4 under the thrust below.

Claims

1, a kind of stop hinge of the desktop that overturns, it has: the rotating shaft that is fixed on the relative frame neutrality line two ends of desktop, this is installed in the bearing axis hole on the frame, it is characterized in that: the rectangular section bar shape of this bearing, its horizontal base plate is fixed on the frame, its erect plate is bearing, except that the heart therein is provided with the axis hole, on the erect plate of this periphery, hole, also be provided with two mutually perpendicular levels and vertical boss rank, the block that is fixed on the relative frame of desktop two is that axle rotates 90 degree with the bearing pin in an angle of 90 degrees scope on these two boss rank then, on the horizontal base plate of bearing, be fixed with the stop pin of the band torsion spring of an inverted "L" shaped by screw, this pin is inserted in the table frame below with its arc bolt point under the thrust of torsion spring, rest the horizontal level of desktop.
