As shown in fig. 5-7, the present invention provides a preferred embodiment of a hinge.

The tightness adjusting structure comprises a first compression block and a second compression block which are arranged on the third rotating shaft 410, the base 100 comprises a third waist-shaped groove 130 for the third rotating shaft 410 to move, the first compression block and the second compression block are respectively arranged on the upper end face and the lower end face of the base 100, and the first compression block or/and the second compression block are/is arranged in an adjustable mode so as to adjust the distance between the first compression block and the second compression block.

The frictional force between the third rotation shaft 410 and the base 100 is changed by adjusting the distance between the first and second pressing blocks, and the contact force between the rotation shaft and the base 100 is increased or decreased, thereby adjusting the movement resistance and stability of the hinge. To adjust the motion performance of the hinge, and to achieve precise control of the friction between the rotation shaft and the base 100. The concrete benefits are as follows:

1. the friction force is increased, so that the movement resistance of the hinge can be increased, devices such as a sliding window are more stable in operation, are not easy to move too rapidly or randomly, and the movement resistance can be reduced by reducing the friction force, so that the operation is lighter and smoother. 2. By adjusting the slack adjuster structure, the third shaft 410 is ensured to stay at a specific position and is prevented from free movement or accidental swing.

In this embodiment, the third rotating shaft 410 includes a screw 411 and a nut 412 that are screwed with each other, a nut 4111 of the screw 411 is used as a first pressing block, and the nut 412 is used as a second pressing block.

The third shaft 410 includes a screw 411 and a nut 412 that are screwed together, wherein a nut 4111 of the screw 411 is used as a first compression block, and the nut 412 is used as a second compression block. This structure allows the interval between the first and second compression blocks to be adjusted by rotating the screw 411 and the nut 412.

Preferably, the screw 411 passes through the third rotating shaft 410 and the base 100 from top to bottom and protrudes out of the lower end surface of the base 100, the nut 4111 of the screw 411 is sleeved on the third rotating shaft 410, the nut 4111 further comprises an annular groove 41111, and the third auxiliary rod 400 is clamped on the annular groove 41111, so that the rotation of the third auxiliary rod 400 is realized more smoothly and is not influenced by the compression of the first compression block and the second compression block. The nut 412 abuts against the lower end surface of the base 100, and the lower side surface of the nut 4111 abuts against the upper end surface of the base 100, thereby clamping the base 100 up and down.

Specifically, the threaded engagement between the screw 411 and the nut 412 provides an adjustable connection. By rotating the screw 411, the distance between the screw thread and the nut 412 can be increased or decreased, thereby adjusting the interval between the first and second compression blocks. This adjustment mechanism allows the contact force and friction between the spindle and the base 100 to be varied as desired.

By rotating the screw 411 and the nut 412, an accurate adjustment of the spacing between the first and second compression blocks can be achieved. Because the screw thread fit between the screw 411 and the nut 412 is adjustable, the adjustment can be carried out at any time according to the needs, and the arrangement of the screw 411 and the nut 412 is a process and a structure which are easy to realize, and the manufacturing difficulty and the manufacturing cost are low.

As shown in fig. 4 and 9, the present invention provides a preferred embodiment of a hinge.

A single tooth structure is further disposed between the end of the first auxiliary rod 200 and the base 100, and the single tooth structure includes a single tooth portion 220 disposed on the first auxiliary rod 200, and a protruding portion 140 disposed on the base 100 and configured to be engaged with the single tooth portion 220.

Since the protrusion 140 is disposed on the base 100 and is fixed, the first auxiliary lever 200 rotates around the first rotation shaft 210 during the swing, and since the single tooth portion 220 is sleeved in the protrusion 140, the first rotation shaft 210 needs to move along the length direction of the base 100 during the swing of the first auxiliary lever 200, so that the first rotation shaft 210 moves left and right with respect to the protrusion 140. The stable movement of the first rotation shaft 210 is realized during the swing of the first auxiliary lever 200 through the single tooth structure, thereby driving the synchronous stable movement of the second rotation shaft 310 and the third rotation shaft 410.

The single tooth portion 220 is a waist-shaped structure extending inward from the edge of the first auxiliary lever 200. The protruding part 140 moves in the waist-shaped structure during the swing of the first auxiliary rod 200, and since the protruding part 140 is arranged at the relative position of the moving track of the first rotating shaft 210 near the middle part, the moving mode of the protruding part 140 is from closed to open, and two sections of moving tracks are arranged, when the first rotating shaft 210 moves from the right side of the first stroke to the middle part, the first rotating shaft 210 is closest to the protruding part 140 in the middle part, so that the protruding part 140 moves along the outer side to the inner side of the waist-shaped structure; when the first rotating shaft 210 moves from the middle of the first stroke to the left, the first rotating shaft 210 gradually moves away from the protruding portion 140, so that the protruding portion 140 moves along the inner side to the outer side of the waist-shaped structure. The smooth movement of the boss 140 serves as a swing limit of the first auxiliary lever 200, so that the single tooth structure can provide stable support and motion control during the operation of the sliding window.

In this embodiment, the waist-shaped structure is extended from the edge of the first auxiliary lever 200 toward the first rotation shaft 210. Since the waist-shaped structure extends from the edge of the first auxiliary lever 200 to the first rotation shaft 210, the overall structure is relatively compact, reducing the additional space required, and making the window system more compact. In addition, in the swinging process of the first auxiliary rod 200, the force applied by the single tooth part 220 to the convex part 140 is not too large, so that the smoothness of the overall movement is improved, and the window is more stable and reliable in the pushing and pulling process.

The waist-shaped structure may be a closed structure or an open structure with an edge opening, the closed structure may prevent the protruding portion 140 from being separated from the waist-shaped structure, and the open structure is convenient for the protruding portion 140 to be installed in the waist-shaped structure.

As shown in FIG. 11, the present invention provides a preferred embodiment of a hinge.

The hinge further includes a linkage 600, and the linkage 600 is rotatably connected to the first auxiliary lever 200 and the second auxiliary lever 300, respectively; the linkage 600 is rotatably connected to the first shaft 210 and the second shaft 310, respectively.

The linkage 600 mainly functions to define the movement track of the second auxiliary lever 300 by the first auxiliary lever 200, and when the first auxiliary lever 200 swings, the linkage 600 transmits the movement to the second auxiliary lever 300, so that the hinge system can move in coordination. The balance and stability of the system are maintained, and the hinge can effectively work in the push-pull process of the sliding window. The first auxiliary rod 200 and the second auxiliary rod 300 are both disposed on an upper end surface of the base 100, the linkage 600 is disposed on a lower end surface of the base 100, and the first rotating shaft 210 and the second rotating shaft 310 are both rotatably connected with the linkage 600 through the base 100. The rotation of the first auxiliary lever 200 and the second auxiliary lever 300 is limited at the upper end surface of the base 100, and the movement of the linkage 600 is not disturbed, and at the same time, the first auxiliary lever 200, the second auxiliary lever 300 and the linkage 600 are vertically layered on the base 100, thereby improving the rigidity and stability of the overall structure. And, with the base 100 as a supporting substrate, the linkage movement and force transmission required for the linkage 600 are optimized to improve the balance of the up-down stress of the first and second rotating shafts 210 and 310.

In this embodiment, the linkage 600 is rotatably connected to the first shaft 210 and the second shaft 310, respectively. Since the actual movement of the first auxiliary lever 200 and the second auxiliary lever 300 is relative movement by the first rotation shaft 210 and the second rotation shaft 310, the linkage 600 transmits the movement to the second rotation shaft 310 when the first rotation shaft 210 moves, thereby enabling the hinge system to move in coordination.

The linkage 600 includes a first through hole and a second through hole, and the first rotating shaft 210 and the second rotating shaft 310 are respectively clamped in the first through hole and the second through hole, so as to realize force transmission.

In this embodiment, the linkage 600 includes a fourth waist-shaped hole 610 that bypasses the third shaft 410. The fourth waist-shaped hole 610 is a specially shaped hole shaped like a waistband, and the position and shape on the link 600 are designed to be adapted to the position and shape of the third rotation shaft 410 so as to avoid the third rotation shaft 410 during the hinge movement without obstructing the movement of the third rotation shaft 410.

The third rotation shaft 410 may interfere or collide with the linkage 600 during the hinge movement, and by designing the fourth waist-shaped hole 610, a sufficient space may be created on the linkage 600 such that the third rotation shaft 410 can freely move without interfering with the linkage 600. The fourth waist-shaped hole 610 of the avoidance third shaft 410 can ensure that the linkage 600 remains stable during the hinge movement, helping to maintain the correct position and interaction between the linkage 600 and other components, thereby ensuring the balance and stability of the overall hinge system. By avoiding the third shaft 410, the fourth kidney-shaped hole 610 may reduce friction and impact between the linkage 600 and the third shaft 410, thereby reducing the risk of wear and damage, helping to extend the life and durability of the hinge.

In this embodiment, the base 100 is provided with a first waist-shaped hole 110 and a second waist-shaped hole 120, the first rotating shaft 210 is movably disposed on the first waist-shaped hole 110, and the second rotating shaft 310 is movably disposed on the second waist-shaped hole 120. The lengths of the first and second waist-shaped holes 110 and 120 are the first and second strokes, and the waist-shaped hole structure is adopted to facilitate the first and second rotating shafts 210 and 310 to pass through the base 100, and to limit the front and back shaking of the first and second rotating shafts 210 and 310, so that the thicknesses of the first and second waist-shaped holes 110 and 120 are matched with the diameters of the first and second rotating shafts 210 and 310.

The foregoing description of the preferred embodiments of the present invention is not intended to limit the scope of the invention, but rather is intended to cover all modifications and variations within the scope of the present invention as defined in the appended claims.
