Description

Technical Field

[0001] The invention relates to the technical field of hinge connectors, and in particular to a double-axis hinge structure for building decoration. Background Art

[0002] A hinge is a mechanical device used to connect two solid objects and allow them to rotate relative to each other. A hinge may have a movable component or be made of foldable material. A hinge can be made of steel, nylon, iron, stainless steel or other materials. Hinges are widely used, from daily applications such as doors, windows, furniture, to special occasions such as two large components.

[0003] At present, most of the hinges in practical application are single-axis hinges. The characteristic of this part of hinges is that they have only one rotation axis. After the two interconnected solids are rotated into place, they are either in the same plane or two parallel surfaces overlap each other. In the case of a single axis, they can only rotate 180 degrees relative to each other, which limits their use. At this time, double-axis hinges are needed, but the double-axis hinges on the market generally include synchronous rotation axis hinges and asynchronous rotation axis hinges. Double-axis hinges cannot switch between synchronous rotation mode and asynchronous rotation mode, and have a single function, which limits the scope of use of the hinge. Summary of the invention

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Embodiment 1: This embodiment discloses a biaxial hinge structure for building decoration, such as Figure 1-Figure 7As shown, it includes: an axle seat 1, on which a pair of rotating shafts 7 are rotatably connected, a connecting block 5 is fixedly connected at the lower end of the rotating shaft 7, a connecting piece 6 is fixedly connected to the connecting block 5, and a plurality of connecting holes are provided on the connecting piece 6, and the connecting piece 6 can be fixedly connected to other objects through a bolt assembly; a synchronous assembly 2, which is provided with a pair of components respectively installed on the two rotating shafts 7, and the synchronous assembly 2 is arranged above the axle seat 1. The two rotating shafts 7 can be synchronously rotated by the synchronous assembly 2, so that the rotation angles of the two rotating shafts 7 are synchronized; a locking assembly 3, which is provided with a pair of components respectively installed on the two rotating shafts 7, and the locking assembly 3 is used to lock and fix the synchronous assembly 2 and the rotating shaft 7, and the locking assembly 3 is arranged between the synchronous assembly 2 and the axle seat 1. When the locking assembly 3 locks the synchronous assembly 2 and the rotating shaft 7, the two rotating shafts 7 rotate synchronously; a lifting assembly 4, on which a groove 11 is provided on the axle seat 1 for movement and cooperation with the lifting assembly 4, and the lifting assembly 4 is arranged in the groove 11, and the lifting assembly 4 is used to drive the locking assembly 3 to rise and fall, thereby controlling the rotation mode of the rotating shaft 7, and thereby switching between synchronous rotation and asynchronous rotation.

[0027] Among them, Figure 4 As shown, the synchronization component 2 includes a first rotating seat 21, which is rotatably connected to the rotating shaft 7 through a bearing. The first rotating seat 21 can only rotate in a circle relative to the rotating shaft 7 and cannot move up and down. A gear 22 is fixedly connected to the first rotating seat 21. The gears 22 on the two first rotating seats 21 are meshed with each other, and a conical groove 23 is provided on the lower surface of the first rotating seat 21, and the diameter of the conical groove 23 gradually decreases from bottom to top.

[0028] like Figure 5-Figure 6As shown, the locking assembly 3 includes a lifting seat 31, which is movably connected to the rotating shaft 7. The lifting seat 31 can move up and down, and the rotating shaft 7 does not drive the lifting seat 31 to rotate. The lifting seat 31 is rotatably connected to the second rotating seat 32, and the second rotating seat 32 is evenly connected with a plurality of clamping blocks 34 along its circumference, which are used to fasten the first rotating seat 21 and the rotating shaft 7. The number of the clamping blocks 34 is four; the surface of the second rotating seat 32 is provided with a sliding groove 35 that slidably cooperates with the clamping block 34, and the sliding groove 35 faces the center direction of the second rotating seat 32, and one side of the clamping block 34 is set as a conical surface structure that cooperates with the conical groove 23, and the other side is set as an arc surface structure that cooperates with the rotating shaft 7; when the lifting seat 31 rises, the clamping block 34 When the lifting seat 31 is lowered, the clamping block 34 is disengaged from the conical groove 23 and no longer locks the rotating shaft 7 and the first rotating seat 21. At this time, the two rotating shafts 7 can rotate independently and no longer rotate together, thereby realizing the switching of the rotating shaft 7 mode.

[0029] like Figure 7 As shown, the lifting assembly 4 includes: a lifting frame 41 with a U-shaped structure, a screw 10 for driving the lifting frame 41 to move up and down is connected in the groove 11, the lifting frame 41 is threadedly connected to the screw 10, and the lifting frame 41 is driven to move up and down when the screw 10 rotates, and a hexagonal head is provided at the head of the screw 10 to facilitate the wrench to rotate the screw, and a pair of sliding holes 49 are provided on both sides of the lifting frame 41, a slider 48 is connected in the sliding hole 49, a bracket 43 is fixedly connected to the slider 48, and one end of the bracket 43 is fixedly connected to the second rotating seat 32.

[0030] During specific implementation: when the two hinge shafts 7 need to rotate synchronously, the lifting frame 41 can be driven to rise by rotating the screw 10. When the lifting frame 41 rises, it drives the two locking components 3 to rise synchronously. The clamping block 34 on the locking component 3 locks and fixes the shaft 7 and the first rotating seat 21, and then the synchronization component 2 and the shaft 7 are locked and fixed. At this time, when the shaft 7 rotates, it will drive the gear 22 to rotate, so that the two shafts 7 can rotate synchronously; when the two shafts 7 do not need to rotate synchronously, the screw 10 can be rotated in the opposite direction to drive the lifting frame 41 to descend, so that the locking component 3 is separated from the synchronization component 2, and the synchronization component 2 and the shaft 7 are no longer locked. At this time, when the shaft 7 rotates, it will not drive the gear 22 to rotate, thereby realizing the switching between the synchronous rotation mode and the asynchronous rotation mode of the hinge shaft 7.

[0031] Embodiment 2: Based on the structure of the above embodiment 1, the difference is that Figure 3 and Figure 6-Figure 7 As shown, in this embodiment, a ring-shaped pressing ring 33 is rotatably connected to the lifting seat 31, and a plurality of clamping strips 36 are evenly arranged on the lower surface of the pressing ring 33 along its circumference, and a limiting strip 37 is arranged on the inner wall of the pressing ring 33, and a limiting groove 71 is arranged on the rotating shaft 7 to be slidably connected with the limiting strip 37, so that the pressing ring 33 rotates when the rotating shaft 7 rotates, and the pressing ring 33 can move up and down along the surface of the rotating shaft 7, and a pressing groove 8 is arranged on the shaft seat 1 to cooperate with the pressing ring 33, and a plurality of clamping grooves 9 are arranged in the pressing groove 8 to cooperate with the clamping strip 36. When the pressing ring 33 is connected to the pressing groove 8, the clamping strip 36 is engaged with the clamping groove 9, and the rotating shaft 7 and the shaft seat 1 are locked, and the rotating shaft 7 cannot continue to rotate; wherein, there is a rotatable connecting groove 71 in the sliding hole 49. The rotating rod 44 and the slider 48 are slidably connected to the rotating rod 44, and a pressure seat 46 is fixedly connected to the rotating rod 44, which is used to drive the slider 48 to descend, so that the pressure ring 33 descends into the pressure groove 8; an arc-shaped pressing piece 47 is fixedly connected to the pressure seat 46, and the two ends of the pressing piece 47 are set as inclined structures to facilitate the pressing piece 47 to be pressed into the arc-shaped groove 42, and the pressing piece 47 is provided with a pair of symmetrical arrangements about the pressure seat 46, and the slider 48 is provided with an arc groove 42 that cooperates with the pressing piece 47, and a rotating disk is provided at the upper end of the rotating rod 44 to facilitate manual rotation of the rotating rod 44; a spring 45 is connected between the slider 48 and the bottom of the sliding hole 49, and the spring 45 is sleeved on the surface of the rotating rod 44, and the spring 45 applies an upward elastic force to the slider 48.

[0032] During specific implementation: after the lifting frame 41 descends to the bottom of the groove 11, when it is necessary to lock one of the rotating shafts 7, one of the rotating rods 44 can be rotated to drive the pressure seat 46 to rotate, so that the pressure plate 47 is rotated into the arc groove 42, and the slider 48 is driven to descend under the pressure of the pressure plate 47, and the pressure ring 33 is driven to descend into the pressure groove 8, and the clamping strip 36 is engaged with the clamping groove 9. At this time, the rotating shaft 7 is locked with the shaft seat 1, and the rotating shaft 7 cannot continue to rotate. At this time, the hinge is in a single-axis rotation mode; similarly, the rotating rod 44 is rotated in the opposite direction to separate the pressure plate 47 from the arc groove 42, and the slider 48 rises under the elastic force of the spring 45, driving the pressure ring 33 to rise and separate from the pressure groove 8, and the rotating shaft 7 can continue to rotate, thereby realizing the function of switching the hinge between single-axis rotation and dual-axis rotation.
