[0035] The preferred embodiment of the utility model is described in detail in conjunction with the drawings.

[0036] As Figures 1 to 10 shown, the utility model provides the preferred embodiment of hinge.

[0037] A hinge includes a first auxiliary rod 200, a second auxiliary rod 300, a third auxiliary rod 400, a support rod 500, and a base 100. The support rod 500 is rotatably connected to the first auxiliary rod 200 and the second auxiliary rod 300, respectively, and the third auxiliary rod 400 is rotatably connected to the first auxiliary rod 200. The second auxiliary rod 300 is provided with a second pivot 310, and the second auxiliary rod 300 is rotatably arranged around the second pivot 310, which is movable along the length direction of the base 100. The first auxiliary rod 200 is provided with a first pivot 210. The first auxiliary rod 200 is rotatably mounted around the first rotating shaft 210, which is movable along the length of the base 100. The third auxiliary rod 400 is provided with a third rotating shaft 410, which is rotatably mounted around the third rotating shaft 410, which is movable along the length of the base 100. A clamping structure is provided between the third rotating shaft 410 and the base 100 to increase the first frictional force between the third rotating shaft 410 and the base 100, or to increase the second frictional force between the base 100 and the third auxiliary rod 400.

[0038] Preferably, a tension adjustment structure is provided between the third rotating shaft 410 and the base 100 to adjust the first frictional force between the third rotating shaft 410 and the base 100, or to adjust the second frictional force between the base 100 and the third auxiliary rod 400.

[0039] Specifically, the support rod 500 is used to install the sliding window. Two hinges are respectively set at the upper and lower ends of the sliding window and are installed on the window frame through the base 100, thereby realizing the sliding operation of the window. Furthermore, the hinges include a closed state and an extended state. In the closed state, the support rod 500 is closed onto the base 100, and is set parallel or nearly parallel, while the first auxiliary rod 200, the second auxiliary rod 300 and the third auxiliary rod 400 assist the rotation of the support rod 500. In the extended state, the support rod 500 is extended relative to the base 100, even extended to a vertical or nearly vertical direction.

[0040] In this embodiment, the two ends of the first auxiliary rod 200 are defined as ends A and B, the two ends of the second auxiliary rod 300 are defined as ends C and D, and the two ends of the third auxiliary rod 400 are defined as ends E and F. Ends A, C, and E are all connected to the base 100, ends B and D are connected to the support rod 500, and end F is connected to the first auxiliary rod 200. In the closed state, the first auxiliary rod 200, the second auxiliary rod 300, the third auxiliary rod 400, and the support rod 500 are all closed onto the base 100. At this time, the left and right directions are defined with the length direction of the base 100. Ends A, F, and B on the first auxiliary rod 200 are arranged sequentially from left to right. End F of the third auxiliary rod 400 is located to the left of end E. End C of the second auxiliary rod 300 is located to the left of end D, and end B is to the left of end D.

[0041] Furthermore, the movement trajectory of the first rotating shaft 210 is defined as the first stroke, the movement trajectory of the second rotating shaft 310 is defined as the second stroke, and the movement trajectory of the third rotating shaft 410 is defined as the third stroke. At this time, the first rotating shaft 210 is on the right side of the first stroke (approaching or at the limit position), the second rotating shaft 310 is on the right side of the second stroke (approaching or at the limit position), and the third rotating shaft 410 is on the right side of the third stroke (approaching or at the limit position).

[0042] During the unfolding process, the support rod 500 rotates clockwise relative to the base 100, the first auxiliary rod 200 rotates counterclockwise around the first rotating shaft 210, and at the same time the first rotating shaft 210 moves to the left along the first stroke, the second auxiliary rod 300 rotates counterclockwise around the second rotating shaft 310, and at the same time the second rotating shaft 310 moves to the left along the second stroke, and the third auxiliary rod 400 rotates clockwise around the third rotating shaft 410, and at the same time the third rotating shaft 410 moves to the left along the third stroke.

[0043] After the support rod 500 is extended to its limit position, the support rod 500 is set vertically or nearly vertically relative to the base 100. The first rotating shaft 210 is on the left side of the first stroke (near or at the limit position), the second rotating shaft 310 is on the left side of the second stroke (near or at the limit position), and the third rotating shaft 410 is on the left side of the third stroke (near or at the limit position).

[0044] In this embodiment, the tension adjustment structure is set at end E of the third rotating shaft 410, thereby increasing / adjusting the first frictional force between the third rotating shaft 410 and the base 100, or increasing / adjusting the second frictional force between the base 100 and the third auxiliary rod 400, so as to increase / adjust the moving resistance of the third rotating shaft 410, increase the stability and damping effect of the hinge, reduce the free movement of the rotating shaft, and make the rotation process more stable.

[0045] like Figures 5 to 7 As shown, this utility model provides a preferred embodiment of the hinge.

[0046] The tension adjustment structure includes a first pressing block and a second pressing block disposed on the third rotating shaft 410. The base 100 includes a third waist-shaped groove 130 for the third rotating shaft 410 to move. The first pressing block and the second pressing block are respectively disposed on the upper end face and the lower end face of the base 100. The first pressing block and / or the second pressing block are adjustable to adjust the distance between them.

[0047] By adjusting the distance between the first and second clamping blocks, the friction between the third pivot 410 and the base 100 is changed, increasing or decreasing the contact force between the pivot and the base 100, thereby adjusting the hinge's motion resistance and stability. This allows for precise control of the friction between the pivot and the base 100 by adjusting the hinge's motion performance. The specific benefits are:

[0048] 1. Increasing friction increases the hinge's resistance to movement, making sliding windows and similar devices more stable during operation and less prone to rapid or unpredictable movement. Reducing friction decreases resistance, making operation easier and smoother. 2. By adjusting the tension adjustment mechanism, the third pivot 410 can be ensured to remain in a specific position, preventing free movement or accidental swaying.

[0049] In this embodiment, the third rotating shaft 410 includes a screw 411 and a nut 412 that are threaded together. The nut 4111 of the screw 411 serves as a first clamping block, and the nut 412 serves as a second clamping block.

[0050] The third rotating shaft 410 includes a screw 411 and a nut 412 that are threaded together, wherein the nut 4111 of the screw 411 serves as a first clamping block and the nut 412 serves as a second clamping block. This structure allows the distance between the first clamping block and the second clamping block to be adjusted by rotating the screw 411 and the nut 412.

[0051] Preferably, the screw 411 passes through the third rotating shaft 410 and the base 100 from top to bottom and protrudes from the lower end face of the base 100. The nut 4111 of the screw 411 is sleeved on the third rotating shaft 410. The nut 4111 also includes an annular groove 41111. The third auxiliary rod 400 is engaged with the annular groove 41111, so that the rotation of the third auxiliary rod 400 is more smoothly realized and is not affected by the clamping of the first clamping block and the second clamping block. The nut 412 abuts against the lower end face of the base 100, and the lower side of the nut 4111 abuts against the upper end face of the base 100, thereby clamping the base 100 from both top and bottom.

[0052] Specifically, the threaded engagement between screw 411 and nut 412 provides an adjustable connection. By rotating screw 411, the distance between the thread and nut 412 can be increased or decreased, thereby adjusting the gap between the first and second clamping blocks. This adjustment mechanism allows the contact force and friction between the rotating shaft and base 100 to be changed as needed.

[0053] By rotating screw 411 and nut 412, the distance between the first clamping block and the second clamping block can be precisely adjusted. Since the threaded engagement between screw 411 and nut 412 is adjustable, it can be adjusted at any time as needed. Furthermore, the design of screw 411 and nut 412 is relatively easy to implement in terms of process and structure, resulting in low manufacturing difficulty and cost.

[0054] like Figure 4 and Figure 9 As shown, this utility model provides a preferred embodiment of the hinge.

[0055] A single-tooth structure is also provided between the end of the first auxiliary rod 200 and the base 100. The single-tooth structure includes a single-tooth portion 220 provided on the first auxiliary rod 200 and a protrusion 140 provided on the base 100 and engaged with the single-tooth portion 220.

[0056] Since the protrusion 140 is fixedly mounted on the base 100, the first auxiliary rod 200 rotates around the first pivot 210 during its swing. Because the single tooth 220 is fitted into the protrusion 140, the first pivot 210 needs to move along the length of the base 100 during the swing, thus allowing the first pivot 210 to move left and right relative to the protrusion 140. The single tooth structure enables stable movement of the first pivot 210 during the swing of the first auxiliary rod 200, thereby driving the synchronous and stable movement of the second pivot 310 and the third pivot 410.

[0057] The single-tooth portion 220 is a waist-shaped structure extending inward from the edge of the first auxiliary rod 200. The protrusion 140 moves within the waist-shaped structure during the swinging of the first auxiliary rod 200. Since the protrusion 140 is positioned near the center of the first rotating shaft 210's movement trajectory, its movement has two segments from closing to opening. When the first rotating shaft 210 moves from the right side of its first stroke to the center, it is closest to the protrusion 140 at the center, so the protrusion 140 first moves inward along the outer side of the waist-shaped structure. When the first rotating shaft 210 moves from the center of its first stroke to the left side, it gradually moves away from the protrusion 140, so the protrusion 140 first moves outward along the inner side of the waist-shaped structure. This smooth movement of the protrusion 140 serves as a limit to the swinging of the first auxiliary rod 200, enabling the single-tooth structure to provide stable support and motion control during the operation of the sliding window.

[0058] In this embodiment, the waist-shaped structure extends from the edge of the first auxiliary rod 200 toward the first pivot 210. Because the waist-shaped structure extends from the edge of the first auxiliary rod 200 to the first pivot 210, the overall structure is relatively compact, reducing the required additional space and making the window system simpler. Furthermore, during the swinging of the first auxiliary rod 200, the force applied by the single tooth 220 to the protrusion 140 is not too great, improving the smoothness of the overall movement and making the window more stable and reliable during sliding.

[0059] The waist-shaped structure can be a closed structure or an open structure with edge openings. The closed structure can prevent the protrusion 140 from detaching from the waist-shaped structure, while the open structure makes it easier for the protrusion 140 to be inserted into the waist-shaped structure.

[0060] like Figure 11 As shown, this utility model provides a preferred embodiment of the hinge.

[0061] The hinge also includes a linkage 600, which is rotatably connected to the first auxiliary rod 200 and the second auxiliary rod 300 respectively; the linkage 600 is rotatably connected to the first rotating shaft 210 and the second rotating shaft 310 respectively.

[0062] The main function of the linkage 600 is to limit the movement trajectory of the second auxiliary rod 300 through the first auxiliary rod 200. When the first auxiliary rod 200 swings, the linkage 600 transmits the motion to the second auxiliary rod 300, thereby enabling the hinge system to move in a coordinated manner. This helps maintain the balance and stability of the system and ensures that the hinge works effectively during the sliding of the window. The first auxiliary rod 200 and the second auxiliary rod 300 are both located on the upper surface of the base 100, and the linkage 600 is located on the lower surface of the base 100. The first rotating shaft 210 and the second rotating shaft 310 both pass through the base 100 and are rotatably connected to the linkage 600. The rotation of the first auxiliary rod 200 and the second auxiliary rod 300 is limited to the upper surface of the base 100, which does not interfere with the movement of the linkage 600. Furthermore, the layered arrangement of the first auxiliary rod 200, the second auxiliary rod 300, and the linkage 600 on the base 100 improves the overall structural rigidity and stability. Furthermore, by using the base 100 as a supporting substrate, the linkage motion and force transmission required by the linkage 600 are optimized, thereby improving the balance of the upper and lower forces on the first rotating shaft 210 and the second rotating shaft 310.

[0063] In this embodiment, the linkage 600 is rotatably connected to the first rotating shaft 210 and the second rotating shaft 310, respectively. Since the actual movement of the first auxiliary rod 200 and the second auxiliary rod 300 is achieved by relative movement of the first rotating shaft 210 and the second rotating shaft 310, when the first rotating shaft 210 moves, the linkage 600 transmits the motion to the second rotating shaft 310, thereby enabling the hinge system to move in a coordinated manner.

[0064] 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 engaged in the first through hole and the second through hole to realize the transmission of force.

[0065] In this embodiment, the linkage 600 includes a fourth waist-shaped hole 610 that avoids the third pivot 410. The fourth waist-shaped hole 610 is a specially shaped hole, similar in shape to a belt. Its position and shape on the linkage 600 are designed to adapt to the position and shape of the third pivot 410 so as to avoid the third pivot 410 during hinge movement and not obstruct the movement of the third pivot 410.

[0066] During hinge movement, the third pivot 410 may interfere with or collide with the linkage 600. By designing the fourth oblong hole 610, sufficient space can be created on the linkage 600, allowing the third pivot 410 to move freely without interfering with the linkage 600. The fourth oblong hole 610, which avoids the third pivot 410, ensures the stability of the linkage 600 during 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 entire hinge system. By avoiding the third pivot 410, the fourth oblong hole 610 reduces friction and impact between the linkage 600 and the third pivot 410, thereby reducing the risk of wear and damage, helping to extend the hinge's service life and improve its durability.

[0067] In this embodiment, the base 100 is provided with a first oblong hole 110 and a second oblong hole 120. The first rotating shaft 210 is movably disposed on the first oblong hole 110, and the second rotating shaft 310 is movably disposed on the second oblong hole 120. The lengths of the first oblong hole 110 and the second oblong hole 120 are the first stroke and the second stroke, respectively. The oblong hole structure facilitates the passage of the first rotating shaft 210 and the second rotating shaft 310 through the base 100, and also restricts the back-and-forth swaying of the first rotating shaft 210 and the second rotating shaft 310. Therefore, the thickness of the first oblong hole 110 and the second oblong hole 120 matches the diameter of the first rotating shaft 210 and the second rotating shaft 310.

[0068] The above description is merely the preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes or modifications made in accordance with the claims of this utility model are covered by this utility model.
