Detailed Description
As shown in fig. 1 to 5, the double-limit flat hinge is a sheet hinge formed by six connecting rod components, and comprises a first connecting rod 1, a second connecting rod 2, a third connecting rod 3, a fourth connecting rod 4, a fifth connecting rod 5 and a sixth connecting rod 6, wherein the fourth connecting rod 4, the fifth connecting rod 5 and the sixth connecting rod 6 are respectively connected, two ends of the third connecting rod 3 are respectively connected with the fifth connecting rod 5 and the first connecting rod 1, the middle part is connected with the fourth connecting rod 4, and two ends of the second connecting rod 2 are respectively connected with the fourth connecting rod 4 and the first connecting rod 1.
In the figure, a first connecting rod 1 is used for connecting a cabinet body of intelligent office equipment, a second connecting rod 2 is used for connecting an office desk panel of the intelligent office equipment, and a sixth connecting rod 6 is used for being fixed on a frame or fixed equipment of the intelligent office equipment.
Further, the connection point between the left end of the first connecting rod 1 and the right end of the second connecting rod 2 is a first connection point 11, the connection point between the right end of the first connecting rod 1 and the right end of the third connecting rod 3 is a second connection point 12, the connection point between the left end of the second connecting rod 2 and the middle part of the fourth connecting rod 4 is a third connection point 13, the connection point between the middle part of the third connecting rod 3 and the right end of the fourth connecting rod 4 is a fourth connection point 14, the connection point between the left end of the third connecting rod 3 and the middle part of the fifth connecting rod 5 is a fifth connection point 15, the connection point between the left end of the fourth connecting rod 4 and the right end of the sixth connecting rod 6 is a sixth connection point 16, and the connection point between the left end of the fifth connecting rod 5 and the middle part of the sixth connecting rod 6 is a seventh connection point 17. The connecting points connect the corresponding connecting rods with the shaft sleeve through tight fit shafts.
The rear side of the sixth connecting rod 6 is respectively connected with the fourth connecting rod 4 and the fifth connecting rod 5 through a sixth connecting point 16 and a seventh connecting point 17, the upper surface of the fourth connecting rod 4 is matched with the lower surface of the fifth connecting rod 5 in shape, the fifth connecting rod 5 is positioned right above the fourth connecting rod 4, and the contact surface of the fifth connecting rod 5 and the fourth connecting rod is A. The rear sides of the fourth connecting rod 4 and the fifth connecting rod 5 are respectively connected with the third connecting rod 3 through a fourth connecting point 14 and a fifth connecting point 15, the rear side of the third connecting rod 3 is connected with the first connecting rod 1 through a second connecting point 12, the rear side of the fourth connecting rod 4 is connected with the second connecting rod 2 through a third connecting point 13, and the rear end of the second connecting rod 2 is connected with the first connecting rod 1 through a first connecting point 11. The third connecting rod 3 is positioned above the second connecting rod 2.
In connection with the related drawings, fig. 2 shows the table top in a flat state, when the table top is horizontal, people can sit on the table top to work and learn, and the contact surfaces A of the fourth connecting rod 4 and the fifth connecting rod 5 are in contact with each other, so that the table top always keeps a horizontal posture and cannot incline downwards.
When the double-limit flat hinge rotates upwards under electric drive or human intervention, each connecting rod of the six-connecting-rod mechanism rotates around the respective shaft, and when the double-limit flat hinge moves at a certain angle, as shown in fig. 3, the contact surface A of the fourth connecting rod 4 and the fifth connecting rod 5 is separated, so that the free movement of each connecting rod is ensured.
When the double-limit flat hinge continues to rotate and reaches a final position (the final angle can be 90 degrees or more than 90 degrees), the contact surface A of the fourth connecting rod 4 and the fifth connecting rod 5 contacts again, and the limit purpose is achieved.
The six-bar linkage of the flat hinge is made of 304 stainless steel plates, and the thickness of the six-bar linkage is preferably 6-8 mm according to the size of the table top. The connecting rods are connected with the shaft sleeve by the tight fit shaft, and the invention has the characteristics of large bearing capacity, small occupied space, bidirectional limit, stable and smooth operation and the like, and is a popular product. The turnover tabletop of the turnover writing table is mainly used for furniture and is connected with the cabinet body through a hinge.
