Detailed Description
It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the invention. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
The first embodiment is as follows:
the embodiment provides a damping hinge turnover table top structure, as shown in fig. 1, which includes a turnover cabinet door 1, a fixed bar counter 4, a damping hinge 2 and a full-open hinge 3, wherein one end of the turnover cabinet door 1 is connected with the fixed bar counter 4 through the full-open hinge 3, and the damping hinge 2 is installed at the bottom of the turnover cabinet door 1; under the normal use state, damping hinge 2 hides and does not expose, guarantees the integrality of outward appearance.
Taking the direction shown in fig. 1 as a reference, the transverse direction of the turnover cabinet door 1 is taken as the length direction, and the other direction which is perpendicular to the length direction and in the same plane is taken as the width direction.
As shown in fig. 2 and 3, the damping hinge 2 includes an arm unit 21, a stopper 22 and a damping unit 23, the stopper 22 and the damping unit 23 are installed at the bottom surface of the flip cabinet door 1, and the stopper 22 is provided near the connection end of the flip cabinet door 1 with the fixed bar counter 4 to be engaged with the arm unit 21.
The installation position of the retainer 22 is adjusted accordingly according to the thickness of the turnover cabinet door 1. Because the support arm unit 21 is always attached to the bottom surface of the turnover cabinet door 1, when the turnover cabinet door 1 is turned over and opened to a certain angle, the tail end of the support arm unit 21 is in contact with the stopper 22 for limiting, so that the support arm unit 21 cannot be turned over continuously and plays a limiting role.
The flexible direction of damping unit 23 keeps unanimous with upset cabinet door 1's length, makes upset cabinet door 1 have the damping effect closing the in-process, guarantees to close the in-process and plays the cushioning effect, prevents to close in-process tong. The damping unit 23 can play a role in lifting assistance when the turnover cabinet door 1 is turned up, so that an operator can conveniently turn up the turnover cabinet door; the damping unit 23 also functions when the door 1 is turned over and the hand is directly released to close or open a small angle.
As shown in fig. 1 and fig. 2, one end of the supporting arm unit 21 is connected to the fixed bar counter 4 through a rotating shaft, the supporting arm unit 21 is in a hook-shaped structure, a torsion spring is installed on the rotating shaft, and when the door 1 of the turnover cabinet is normally in a horizontal state, a spring coil of the supporting arm unit 21 is in a rotating state to generate a certain torque, so that the supporting arm unit 21 is always attached to the bottom of the door 1 of the turnover cabinet, and the door 1 of the turnover cabinet is moved along the lower surface of the door 1 of the turnover cabinet in a turnover process.
The arm unit 21 is restrained by the stopper 22 after rotating a certain angle, and the arm unit 21 itself also has a self-restraining function to ensure that the damping hinge does not rotate beyond a certain angle. In the overturning and falling process of the overturning cabinet door 1, the front end of the support arm unit 21 is in contact with the damping unit 23, and the damping unit 23 starts to generate a damping buffer effect, so that the overturning cabinet door 1 slowly falls down.
The 3 of folding paper of wide open sets up a plurality ofly along 1 width direction interval of upset cabinet door, and this embodiment sets up two wide open and folds paper 3, can effectively guarantee 1 axiality of upset cabinet door, can realize accurate location in 1 upset in-process of upset cabinet door.
As shown in fig. 4, the fully open type hinge 3 includes a first mounting seat 31, a second mounting seat 32 and a plurality of hinges 33, the first mounting seat 31 is fixed on the vertical face of the turnover cabinet door 1, the second mounting seat 32 is fixed on the end face of the fixed bar counter 4, and the plurality of hinges 33 are connected between the first mounting seat 31 and the second mounting seat 32.
The hinges 33 are even number and distributed in staggered (staggered) distribution, and the hinges 33 are connected through a rotating shaft. The alternately distributed hinges 33 form one group, i.e. two groups of hinge structures.
Taking six hinges 33 as an example, each group of hinges 33 is three, wherein one ends of three hinges 33 are connected through a fixed shaft, two ends of the fixed shaft extend out from the surface of the outer hinge 33 for a certain length, and the extending section of the fixed shaft is matched with a groove 34 formed in the inner wall of the first mounting seat 31.
One ends of the other three hinges 33 are connected through a fixed shaft which also has a protruding section which is matched with a groove 34 on the inner wall of the second mounting seat 32; the fixed shaft moves in the groove 34 during the rotation of the full open hinge 3.
The hinge 33 of this embodiment is an arc structure, and the hinge 33 protrudes toward the inside of the door 1 of the turnover cabinet in the state that the door 1 of the turnover cabinet is connected with the fixed bar counter 4.
In the embodiment, the support arm unit 21 is used for increasing the angle limitation in the opening process of the turnover cabinet door 1 so as to prevent the turnover cabinet door 1 from being pinched in the opening process; the turnover cabinet door 1 has a damping effect in the closing process, so that the closing process is guaranteed to play a role in buffering, and the closing process is prevented from clamping hands. Under the normal use state, damping hinge 2 hides and does not expose, guarantees the integrality of outward appearance.
This embodiment can adapt to different thickness upset cabinet doors 1, and is easy to assemble, need not to process current bar counter.
The second embodiment:
the embodiment provides a EMUs kitchen, installs the upset mesa structure of embodiment one, still include the kitchen railway carriage or compartment body, fixed bar counter is installed in kitchen railway carriage or compartment internally.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
