Description

[Technical field]

[0001] The invention relates to a scissor-type track erasable window hidden hinge. [Background technology]

[0002] In the past, most of the hardware accessories for wipeable hidden hinges for doors and windows used parallelogram sliding tracks. There was a virtual position when the hinge was initially opened, and a wrap angle was required to assist in returning to the original position when closing. In addition, the support arm, also called the window sash fixing plate, was used to connect the support arm and the slider. The stress on some of the connecting rods was too concentrated, which easily led to deformation of the connecting rod and wear of the related rivets connected to it. In addition, the track for the slider to slide in the hinge slide was mostly a single-line slide. When the window sash was installed on the window frame, the hinge needed to be connected to the top and bottom. The hinge was under normal force when it was at the bottom, but it was not under force in the opposite direction when it was at the top of the window sash, which usually caused the hinge slider to warp down and the window sash to sag, reducing the performance of the window sash and the life of the hinge. In particular, with the upgrade of the performance of the window sash, its weight is getting heavier, and the hinges of the existing structure are increasingly unable to meet the demand.

[0003] The present invention is made based on this situation. [Summary of the invention]

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a simple-structured scissor-type track wipeable window hidden hinge, which not only opens smoothly and freely, locks and returns naturally and accurately, but also bears weight scientifically and reasonably, thereby increasing the hinge's load-bearing capacity and stability and safety in use.

[0005] The present invention is achieved through the following technical solutions:

[0006] A scissor-type track wipeable window hidden hinge, comprises a slide slot, a first connecting rod, a second connecting rod, a long rod and a supporting arm, characterized in that: a slider is slidably connected to the slide slot, one end of the long rod is rotatably connected to the slide slot, the second connecting rod crosses the first connecting rod and the second connecting rod is supported at the bottom of the first connecting rod, the second connecting rod is rotatably connected to the first connecting rod at the intersection, one end of the second connecting rod is rotatably connected to the slider and is also slidably connected to the slider along the sliding direction of the slider, one end of the first connecting rod is rotatably connected to the slider and the rotation connection point is located between the long rod and the second connecting rod, the other end of the first connecting rod is rotatably connected to one end of the supporting arm, the other end of the second connecting rod is rotatably connected to the other end of the long rod and the two are rotatably connected to the middle part of the supporting arm and are also slidably connected to the supporting arm along the length direction of the supporting arm.

[0007] A scissor-type track wipeable window hidden hinge as described above is characterized in that: the slide groove includes a bidirectional C-shaped sliding track with C-shaped grooves arranged opposite to each other on the left and right, the C-shaped groove on the left is lower than the C-shaped groove on the right, the slider includes a slider body, and the left and right sides of the slider body are respectively provided with left and right slides inserted into the left and right C-shaped grooves and slidingly matched with the C-shaped grooves, the slide on the right side protrudes above the slider body, and a slot with a notch facing the left side is provided on the right slide, and the slot is located above the C-shaped groove on the left and the slider body, one end of the second connecting rod is rotatably connected to the slider body, and when the hinge is opened, the end is laterally inserted into the slot and restricted from tilting upward by the upper wall of the slot.

[0008] The scissor-type track wipeable window hidden hinge as described above is characterized in that the sliding groove includes a stepped groove bottom which is low on the left and high on the right, the C-shaped groove on the left is arranged on the low step of the groove bottom, and the C-shaped groove on the right is arranged on the high step of the groove bottom.

[0009] The scissor-type track wipeable window hidden hinge as described above is characterized in that the second connecting rod is rotatably connected to the slider via a rivet, and the slider is provided with a first strip hole along its sliding direction for the rivet to slide and rotate inside.

[0010] The scissor-type track wipeable window hidden hinge as described above is characterized in that: the second connecting rod and the long rod are hinged by rivets and are rotatably connected to the support arm by the rivet, and the middle part of the support arm is provided with a second strip hole along its length direction for the rivet to slide and rotate inside.

[0011] The scissor-type track wipeable window hidden hinge as described above is characterized in that the long rod is located below the second connecting rod and the support arm, and the first connecting rod is located below the support arm.

[0012] The scissor-type track wipeable window hidden hinge as described above is characterized in that the slide groove is a sheet metal part or a die-casting part.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. The hinge of the present invention has a definite scissor-type motion trajectory, which can avoid the use of an angle wrap and a guide head structure. It not only opens smoothly and freely, but also returns naturally and accurately. It also simplifies the hinge structure, making the hinge structure more compact, reducing the space volume, and being more beautiful and generous. In addition, the first connecting rod is connected to the proximal end of the support arm. When the hinge is installed at the bottom of the window sash to support the window sash, the first connecting rod is usually subjected to a larger force, and the scissor structure formed by the cross arrangement of the second connecting rod and the first connecting rod supports the first connecting rod from the middle through the second connecting rod, thereby shortening the arm length suspended between the force point of the first connecting rod and the support point, relatively reducing the torsion of the first connecting rod subjected to the action of the window sash, and at the same time making the first connecting rod have two connection points and support points of the second connecting rod and the slider, dispersing the force of the first connecting rod rotation connection structure, such as reducing the force of the rivet when the rotation connection is through a rivet, avoiding excessive stress concentration. Therefore, the hinge has better structural strength and better load-bearing effect.

[0015] 2. The present invention matches the left and right C-shaped grooves with the left lower and the right higher, and the left and right slides, and sets a leftward side slot on the higher right slide for the end of the second connecting rod to be inserted when opening. When the hinge is installed at the bottom of the window sash to support the window sash, when opening, a lever is formed between the window sash, the second connecting rod, the slider, the rivet connecting the second connecting rod and the slider, the slot and the right C-shaped groove. The second connecting rod is supported by the left side of the slider, and is pressed down by the gravity of the window sash at the screwed-out end, while a downward pulling force is applied at the other end by the rivet connected to the slider, and the end is screwed into the slot, and the upper wall of the slot clamps the end to form a downward pressure, and the slot then transmits the force to the right C-shaped groove through the right slide to disperse the force of the rivet and the related connection structure, so that the second connecting rod supports the first connecting rod while avoiding the stress concentration of the second connecting rod and its related connection structure, and the load-bearing effect is better; and the force arm of the pressure at the slot is longer than that at the rivet, which increases the force arm of the end and reduces the force. At the same time, the hinge installed in the reverse direction at the top of the window sash forms another lever between the window sash, the second connecting rod, the slider, the rivet connecting the second connecting rod and the slider, and the left C-shaped groove. The second connecting rod is pulled down by the gravity of the window sash at the screwed-out end, and the second connecting rod is connected to the slider through rivets, and an upward pulling force is provided through the cooperation of the left slide and the left C-shaped groove to prevent the hinge from pulling and deforming and causing the window sash to sag when applied in the reverse direction. Through the double-lever structure, the force of the entire hinge is more scientific and reasonable in application, and the load-bearing effect of the window sash in both static and dynamic conditions is effectively guaranteed, making the window sash more reliable and safe during movement, ensuring its stability in use, and making opening and locking more natural and smooth.

[0022] The present invention will be further described below in conjunction with the accompanying drawings:

[0023] In the present invention, the side where the supporting arm is located when the device is opened is the left side, and the other side is the right side.

[0024] like Figures 1 to 5 The scissor-type track wipeable window hidden hinge shown includes a slide groove 1, a first connecting rod 2, a second connecting rod 3, a long rod 4 and a supporting arm 5, the slide groove 1 is slidably connected with a slider 6, one end of the long rod 4 is rotatably connected to the slide groove 1, the second connecting rod 3 crosses the first connecting rod 2 and the second connecting rod is supported at the bottom of the first connecting rod 2, the second connecting rod 3 is rotatably connected to the first connecting rod 2 at the intersection, one end of the second connecting rod 3 is rotatably connected to the slider 6 and is also slidably connected to the slider 6 along the sliding direction of the slider 6, one end of the first connecting rod 2 is rotatably connected to the slider 6 and the rotation connection point is located between the long rod 4 and the second connecting rod 3, the other end of the first connecting rod 2 is rotatably connected to one end of the supporting arm 5, the other end of the second connecting rod 3 and the other end of the long rod 4 are rotatably connected and both are rotatably connected to the middle part of the supporting arm 5 and are also slidably connected to the supporting arm 5 along the length direction of the supporting arm 5. The hinge has a definite scissor-type motion trajectory, which can avoid the use of an angle wrap and a guide head structure. It not only opens smoothly and freely, but also returns naturally and accurately. It also simplifies the hinge structure, making the hinge structure more compact, reducing the spatial volume, and being more beautiful and elegant. In addition, the first connecting rod 2 is connected to the proximal end of the support arm 5. When the hinge is installed at the bottom of the window sash to support the window sash, the first connecting rod 2 is usually subjected to a large force, and the scissor structure formed by the cross-arrangement of the second connecting rod 3 and the first connecting rod 2 supports the first connecting rod 2 from the middle through the second connecting rod 3, thereby shortening the arm length suspended between the force point of the first connecting rod 2 and the support point, relatively reducing the torsion of the first connecting rod 2 under the action of the window sash, and at the same time making the first connecting rod 2 have two connection points and support points, the second connecting rod 3 and the slider 6, dispersing the force of the rotation connection structure of the first connecting rod 2, such as when the rotation connection is through a rivet, reducing the force on the rivet to avoid excessive stress concentration. Therefore, the hinge has better structural strength and better load-bearing effect.

[0025] The rotational connection between the above-mentioned different components can be connected by rivets.

[0026] The second connecting rod 3 is rotatably connected to the slider 6 via a rivet. The slider 6 is provided with a first strip hole 64 along its sliding direction for the rivet to slide and rotate inside, so that the second connecting rod 3 is slidably connected to the slider 6 while being rotatably connected to the slider 6, and the structure is compact.

[0027] The second connecting rod 3 and the long rod 4 are hinged by rivets and are rotatably connected to the bracket 5 by the rivets. The middle part of the bracket 5 is provided with a second strip hole 51 along its length direction for the rivet to slide and rotate inside. The second connecting rod 3 and the long rod 4 are rotatably connected to the bracket 5 and are also slidably connected to the bracket 5, and the structure is compact.

[0028] like Figure 2 and Figure 3 As shown, the slide 1 includes a bidirectional C-shaped sliding track with C-shaped grooves 11 arranged opposite to each other on the left and right sides, the C-shaped groove 11 on the left side is lower than the C-shaped groove 11 on the right side, and the slider 6 includes a slider body 61, and the left and right sides of the slider body 61 are respectively provided with left and right slides 62 inserted into the left and right C-shaped grooves 11 and slidingly matched with the C-shaped grooves 11, the right slide 62 protrudes above the slider body 61, and the right slide 62 is provided with a slot 63 with a notch facing the left side, and the slot 63 is located above the C-shaped groove 11 on the left and the slider body 61, one end of the second connecting rod 3 is rotatably connected to the slider body 61, and this end is laterally inserted into the slot 63 when the hinge is opened and is restricted from tilting upward by the upper wall of the slot 63.

[0029] When the hinge is installed at the bottom of the window sash to support the window sash, when the hinge is opened, a lever is formed between the window sash, the second connecting rod 3, the slider 6, the rivet connecting the second connecting rod 3 and the slider 6, the clamping groove 63 and the right C-shaped groove 11. The second connecting rod 3 is supported by the left side of the slider 6, and is pressed down by the gravity of the window sash at the screwed-out end, while a downward pulling force is applied at the other end through the rivet rotatably connected to the slider 6, and the end is screwed into the clamping groove 63, and the upper wall of the clamping groove 63 clamps the end to form a downward pressure, and the clamping groove 63 then transmits the force to the right C-shaped groove 11 through the right slide 62 to disperse the force on the rivet and the related connection structure, so that the second connecting rod 3 supports the first connecting rod 2 while avoiding the stress concentration of the second connecting rod 3 and its related connection structure; and the force arm of the pressure at the clamping groove 63 is longer than that at the rivet, which increases the force arm of the end and reduces the force. At the same time, the hinge installed in the reverse direction at the top of the window sash forms another lever between the window sash, the second connecting rod 3, the slider 6, the rivet connecting the second connecting rod 3 and the slider 6, and the left C-shaped groove 11. The second connecting rod 3 is pulled down by the gravity of the window sash at the unscrewed end, and the second connecting rod 3 is connected to the slider 6 through the rivet, and an upward pulling force is provided through the cooperation of the left slide 62 and the left C-shaped groove 11 to prevent the hinge from pulling and deforming and causing the window sash to sag when applied in the reverse direction. The double lever structure makes the entire hinge more scientific and reasonable in application, and the load-bearing effect of the window sash in both static and dynamic conditions is effectively guaranteed, making the window sash more reliable and safe during movement, ensuring its stability in use, and making opening and locking more natural and smooth.

[0030] The chute 1 comprises a stepped chute bottom 12 which is lower on the left and higher on the right. The C-shaped chute 11 on the left is arranged on the lower step of the chute bottom 12 , and the C-shaped chute 11 on the right is arranged on the higher step of the chute bottom 12 , so that the chute 1 has better structural strength.

[0031] The slide 1 is a sheet metal part. Figure 3 As shown; of course, the chute 1 can also be a die casting, such as Figure 5 shown.

[0032] The long rod 4 is located below the second connecting rod 3 and the support arm 5, and the first connecting rod 2 is located below the support arm 5. It has a compact structure and a small size. When the hinge is used below the window sash, the force of the second connecting rod 3 is shared by the long rod 4, making the force more scientific and reasonable, avoiding excessive stress concentration.
