Door spindle hinging device capable of adjusting torsion

Abstract

The invention provides a door spindle hinging device capable of adjusting torsion, which mainly comprises a group of hinging units, a group of torsion providing units and a group of torsion adjusting units. The group of hinging units is provided with a first door sheet and a second door sheet pivoted with each other; the torsion providing units are provided with a torsion spring which a providing door plate generates torsion restoration force; and the torsion adjusting units are provided with a mandrel and a group of cam mechanisms, and the mandrel can drive the torsion spring through the cam mechanisms to adjust the size of the torsion, therefore, the invention has the effects of adjusting the torsion, and closing and opening the door with smooth operation, and is suitable for high bearing load.

Description

technical field [0001] The invention relates to a hinge device, in particular to a door shaft hinge device with adjustable torsion applied to the pivoting application of the door shaft. Background technique [0002] Generally, the door panel is installed and fixed on the door frame by means of a hinge device, and the door panel is rotatably opened and closed in the door frame through the hinge device, see figure 1 As shown, a hinge device 10 generally having a torque recovery function includes a first seat plate 11, a second seat plate 12, a washer 13, a mandrel 14, two fixing screws 15, a torsion spring 16, an adjustment The pipe sleeve 17 and an adjustment tip 18, the first seat plate 11 and the second seat plate 12 are installed on the door panel and the door frame (not shown in the figure) respectively, and each of them is provided with a pivoting pipe portion 111 corresponding to each other at the side , 121, the pivoting pipe portion 111 and the pivoting pipe portion ...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned hinge device 10 does have the effect of torque recovery, but its usability is still lacking. Generally, the hinge device 10 uses the adjustment pin 18 to abut against the inner wall of the chute 122 to stop, and then the adjustment sleeve 17 starts to adjust the torsion spring. 16 is twisted to generate torsion, but the chute 122 can only be opened for a short distance, so the adjustment of the torsion is quite limited, and the hinge device 10 is adjusted by inserting the adjustment pin 18 into the socket 172 at different positions. This kind of plug-in adjustment action is quite time-consuming and inconvenient. In addition, the first seat plate 11 and the second seat plate 12 are overlapped and combined, and a washer 13 is used for running-in between the two. The contact presses against the washer 13. When the first seat plate 11 is installed on a heavy door plate, the bearing weight will be transmitted to the torsion spring 16 through the mandrel 14 and cause heavy pressure damage, so the service life is short, and the first When the seat plate 11 and the second seat plate 12 are pivoted, great frictional resistance will also be generated, resulting in the phenomenon that the opening and closing of the door is prone to jamming and unsmooth
