Description

Technical Field

[0001] This utility model relates to the field of daily hardware accessories technology, specifically to a single-tooth hinge. Background Technology

[0002] A hinge is a device used to connect a window frame and a window sash, allowing the window sash to be opened and closed horizontally. Sliding window hinges typically consist of two interconnected parts, one attached to the window frame and the other to the window sash. Depending on the design and installation location, various types of sliding window hinges are available, including side-opening hinges, top-opening hinges, and bottom-opening hinges. The main function of a sliding window hinge is to support the opening and closing of the window sash and provide a stable axis of motion. It allows the window sash to be smoothly pushed and pulled along the hinge axis to achieve the opening and closing action of the window.

[0003] In traditional sliding window designs, multi-tooth hinges are used to limit the rotation direction and movement position of the auxiliary rod, enabling the window to open at its extreme positions. However, multi-tooth hinges have some problems, including:

[0004] Implementing a multi-tooth structure requires creating multiple openings in the auxiliary rod, which may reduce the rod's rigidity. The auxiliary rod bears a certain amount of force during the operation of the sliding window; if its rigidity is reduced, the rod may not be strong enough to support the weight of the window, thus affecting its stability and durability.

[0005] In a multi-tooth structure, multiple teeth need to engage with multiple protrusions, which may reduce the upper limit of the support force at a single point. When the force during the window sliding process is concentrated on a single tooth and protrusion, these components may be subjected to greater pressure, making them prone to wear and damage. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a single-tooth hinge that addresses the above-mentioned defects of the prior art, thereby solving the problem that multi-tooth structures are prone to wear and damage.

[0007] The technical solution adopted by this utility model to solve its technical problem is: to provide a single-tooth hinge, the single-tooth hinge including a first auxiliary rod, a second auxiliary rod, a support rod and a base;

[0014] A preferred embodiment is that the single-tooth hinge further includes a linkage component, which is rotatably connected to the first auxiliary rod and the second auxiliary rod respectively.

[0016] A preferred embodiment is that the first auxiliary rod and the second auxiliary rod are both disposed on the upper end face of the base, the linkage is disposed on the lower end face of the base, and the first rotating shaft and the second rotating shaft both pass through the base and are rotatably connected to the linkage.

[0032] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] like Figures 1 to 8As shown, this utility model provides a preferred embodiment of a single-tooth hinge.

[0034] A single-tooth hinge includes a first auxiliary rod 200, a second auxiliary rod 300, a support rod 400, and a base 100. The support rod 400 is rotatably connected to the first auxiliary rod 200 and the second auxiliary rod 300. The second auxiliary rod 300 is provided with a second rotating shaft 310, which rotates around the second rotating shaft 310 and moves along the length of the base 100. The first auxiliary rod 200 is provided with a first rotating shaft 220, which rotates around the first rotating shaft 220 and moves along the length of the base 100. 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 210 provided on the first auxiliary rod 200 and a protrusion 110 provided on the base 100 and engaged with the single-tooth portion 210.

[0035] Specifically, the support rod 400 is used to install the sliding window. Two single-tooth 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 single-tooth hinge has a closed state and an extended state. In the closed state, the support rod 400 is closed onto the base 100, and is set parallel or nearly parallel, while the first auxiliary rod 200 and the second auxiliary rod 300 assist the rotation of the support rod 400. In the extended state, the support rod 400 is extended relative to the base 100, even extended to a vertical or nearly vertical direction.

[0036] In this embodiment, since the protrusion 110 is fixedly mounted on the base 100, the first auxiliary rod 200 rotates around the first pivot 220 during the swinging process. Because the single tooth 210 is fitted into the protrusion 110, the first pivot 220 needs to move along the length of the base 100 during the swinging process, thereby causing the first pivot 220 to move left and right relative to the protrusion 110. Here, the left and right direction refers to the length direction of the base 100. Specific details of the single tooth structure in the closed and unfolded states are provided (defining the two ends of the first auxiliary rod 200 as ends A and B, and the two ends of the second auxiliary rod 300 as ends C and D, where ends A and C are connected to the base 100, and ends B and D are connected to the support rod 400):

[0037] refer to Figure 2 and Figure 4In the closed state, the support rod 400 closes onto the base 100. At this time, ends A and B of the first auxiliary rod 200 are both positioned or close to the base 100, with end A positioned to the left of end B. Ends C and D of the second auxiliary rod 300 are also both positioned or close to the base 100, with end C positioned to the left of end D, and end B positioned to the left of end D. The movement trajectory of the first rotating shaft 220 is defined as the first stroke, and the movement trajectory of the second rotating shaft 310 is defined as the second stroke. In the closed state, the first rotating shaft 220 is positioned at the right end of the first stroke (approaching or at its limit position), and the second rotating shaft 310 is positioned at the right end of the second stroke (approaching or at its limit position).

[0038] refer to Figure 1 , Figure 3 , Figure 5 and Figure 6 As the closed state changes to the unfolded state, the single tooth 210 rotates around the first rotating shaft 220, while the protrusion 110 continues to move relative to it within the single tooth 210. Under the limitation of the protrusion 110 and the first stroke, the first rotating shaft 220 moves from the right side to the left side of the first stroke until it is fully unfolded and is positioned at the left end of the first stroke (close to or at the limit position). Similarly, the second rotating shaft 310 also moves from the right side to the left side of the second stroke until it is fully unfolded and is positioned at the left end of the second stroke (close to or at the limit position). Meanwhile, the support rod 400 rotates relative to the base 100 from a parallel or nearly parallel posture to a vertical or nearly vertical posture.

[0039] in, Figure 1 and Figure 5 This is the state when the support rod 400 is rotated halfway. Figure 2 and Figure 6 This is the state when the support rod 400 is rotated to its limit position.

[0040] In this embodiment, the single-tooth structure is relatively simple in design, easy to manufacture and install, and provides stable support and motion control for the sliding window's operation. The single-tooth structure effectively utilizes space, allowing the support rod 400 and auxiliary rod to be installed on the window frame and base 100 without requiring additional complex mechanisms or a large amount of space. By controlling the movement of the pivot, the single-tooth structure achieves smooth movement of the sliding window, ensuring its stability and balance during the sliding process and preventing wobbling or instability. Because only one single tooth 210 and protrusion 110 are provided, the probability of damage is greatly reduced compared to multiple tooth structures, increasing the frequency of use and ensuring long-term stable sliding operation. Furthermore, due to the relative simplicity of the single-tooth structure, maintenance and repair are also relatively easy.

[0041] In this embodiment, the single-tooth hinge further includes a first pad 101 and a second pad 102. The first pad 101 is disposed between the first auxiliary rod 200 and the base 100, and the second pad 102 is disposed between the second auxiliary rod 300 and the base 100. The first pad 101 and the second pad 102 are a gasket or pad installed between the auxiliary rod and the base 100. The function of the first pad 101 and the second pad 102 is to provide support and cushioning to ensure a stable connection and smooth movement between the first auxiliary rod 200 and the base 100, while reducing frictional damage to the base 100.

[0042] The protrusion 110 is preferably disposed on the first pad 101.

[0043] By placing pads between the first auxiliary rod 200 and the base 100 and between the second auxiliary rod 300 and the base 100, the stability and durability of the hinge system can be increased, friction and vibration between the rods can be reduced, and the tightness of the connection can be maintained, thereby providing more reliable sliding window operation.

[0044] In this embodiment, the second auxiliary rod 300 is rotatably connected to the end of the support rod 400, and the first auxiliary rod 200 is rotatably connected to the middle region of the support rod 400. The second auxiliary rod 300 is rotatably connected to the end of the support rod 400, with one end of the second auxiliary rod 300 connected to the end of the support rod 400 via a rotatable connection. Using suitable connectors, such as hinges, bearings, or other rotary connection devices, the second auxiliary rod 300 can rotate around the connection point, achieving motion linkage with the support rod 400. The middle region of the first auxiliary rod 200 is rotatably connected to the middle region of the support rod 400 via a rotatable connection. Using suitable connectors, such as hinges, bearings, or other rotary connection devices, the first auxiliary rod 200 can rotate around the connection point, achieving motion linkage with the support rod 400. The first auxiliary rod 200, the second auxiliary rod 300, and the support rod 400 form a stable connection system that can cooperate to realize the movement of the sliding window, ensuring more reliable and convenient operation of the sliding window.

[0045] like Figure 7 As shown, this utility model provides a preferred embodiment of a single-tooth structure.

[0046] The single toothed portion 210 is a waist-shaped structure 210 extending inward from the edge of the first auxiliary rod 200. The protrusion 110 moves within the waist-shaped structure 210 during the swinging of the first auxiliary rod 200. Since the protrusion 110 is positioned near the center of the movement trajectory of the first rotating shaft 220, the movement of the protrusion 110 has two segments from closing to opening. When the first rotating shaft 220 moves from the right side of the first stroke to the center, the distance between the first rotating shaft 220 and the protrusion 110 is closest when the first rotating shaft 220 is in the center. Therefore, the protrusion 110 first moves inward along the outer side of the waist-shaped structure 210. When the first rotating shaft 220 moves from the center of the first stroke to the left side, the first rotating shaft 220 gradually moves away from the protrusion 110. Therefore, the protrusion 110 first moves outward along the inner side of the waist-shaped structure 210. The smooth movement of the protrusion 110, acting as a swing limiter for the first auxiliary rod 200, enables the single-tooth structure to provide stable support and motion control during the operation of the sliding window. (See reference...) Figures 4 to 6 .

[0047] In this embodiment, the waist-shaped structure 210 extends from the edge of the first auxiliary rod 200 toward the first pivot 220. Because the waist-shaped structure 210 extends from the edge of the first auxiliary rod 200 to the first pivot 220, 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 210 to the protrusion 110 is not too great, improving the smoothness of the overall movement and making the window more stable and reliable during sliding.

[0048] The waist-shaped structure 210 can be a closed structure or an open structure with edge openings. The closed structure can prevent the protrusion 110 from detaching from the waist-shaped structure 210, while the open structure makes it easy for the protrusion 110 to be inserted into the waist-shaped structure 210.

[0049] like Figure 9 As shown, this utility model provides a preferred embodiment of the linkage component 400.

[0050] The single-tooth hinge also includes a linkage 400, which is rotatably connected to the first auxiliary rod 200 and the second auxiliary rod 300. The main function of the linkage 400 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 400 transmits the motion to the second auxiliary rod 300, thereby enabling the single-tooth hinge system to move in a coordinated manner. This helps maintain the system's balance and stability, and ensures that the single-tooth hinge works effectively during the sliding of the window.

[0051] In this embodiment, the linkage 400 is rotatably connected to the first rotating shaft 220 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 220 and the second rotating shaft 310, when the first rotating shaft 220 moves, the linkage 400 transmits the motion to the second rotating shaft 310, thereby enabling the single-tooth hinge system to move in a coordinated manner.

[0052] The linkage 400 includes a first through hole and a second through hole, and the first rotating shaft 220 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.

[0053] like Figures 1 to 9 As shown, this utility model provides a preferred embodiment of the base and the linkage component.

[0054] The first auxiliary rod 200 and the second auxiliary rod 300 are both disposed on the upper end surface of the base 100, and the linkage 400 is disposed on the lower end surface of the base 100. The first rotating shaft 220 and the second rotating shaft 310 both pass through the base 100 and are rotatably connected to the linkage 400.

[0055] First, 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 will not interfere with the movement of the linkage 400. At the same time, the first auxiliary rod 200, the second auxiliary rod 300, and the linkage 400 are arranged in layers on the base 100, which improves the rigidity and stability of the overall structure. Second, with the base 100 as a supporting substrate, the linkage motion and force transmission required by the linkage 400 are optimized, thereby improving the balance of the vertical forces on the first rotating shaft 220 and the second rotating shaft 310.

[0056] In this embodiment, a sliding groove 103 is provided on the lower end face of the base 100, and the linkage 400 is slidably disposed in the sliding groove 103. The linkage 400 can slide in the sliding groove 103 of the base 100. When the first rotating shaft 220 and the second rotating shaft 310 move, the force is transmitted through the linkage 400, which enables the linkage 400 to slide effectively in the sliding groove 103 and is limited to its extreme position by the sliding groove 103.

[0057] A sliding groove 103 can be formed between the notch and the base 100 by adding a support plate with a notch to the lower end face of the base 100.

[0058] In this embodiment, the base 100 is provided with a first oblong hole 120 and a second oblong hole 130. The first rotating shaft 220 is movably disposed on the first oblong hole 120, and the second rotating shaft 310 is movably disposed on the second oblong hole 130. The lengths of the first oblong hole 120 and the second oblong hole 130 are the first stroke and the second stroke, respectively. The oblong hole structure facilitates the passage of the first rotating shaft 220 and the second rotating shaft 310 through the base 100, and also restricts the back-and-forth swaying of the first rotating shaft 220 and the second rotating shaft 310. Therefore, the thickness of the first oblong hole 120 and the second oblong hole 130 matches the diameter of the first rotating shaft 220 and the second rotating shaft 310.

[0059] 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.
