Description

Technical Field

[0001] This invention relates to the field of hardware profile technology, and in particular to a high load-bearing and wear-resistant planar sliding hinge. Background Technology

[0002] Casement hinges, as a type of opening and closing connector with good stability, high adjustability, and wide applicability, are widely used in operable doors and windows. Casement sliding hinges, in particular, feature a sliding support rod connecting the mounting base and the mounting rod used to install the door / window sash. This means that the longer end of the support rod connected to the mounting base is made a slidable and rotatable connection, thus shortening the length of the support rod and providing high stability. However, current casement sliding hinges suffer from the problem of the short rod, which serves as the main support, being prone to loosening and affecting overall stability. Furthermore, the currently used curved limiting components cannot effectively control the opening angle of the door / window. Summary of the Invention

[0003] The purpose of this invention is to provide a planar sliding hinge, specifically a planar sliding hinge with high load-bearing capacity, stable structure and wear resistance.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a high load-bearing and wear-resistant swing-wing hinge, comprising a mounting base, a mounting rod, a swing-wing connecting rod, a first support connecting rod, and a second support connecting rod; one end of the first support connecting rod is rotatably connected to the mounting base, and the other end is rotatably connected to the rear end of the mounting rod; one end of the swing-wing connecting rod is rotatably connected to a slider, which is slidably connected to the mounting base, and the other end is rotatably connected to the middle of the mounting rod; one end of the second support connecting rod is rotatably connected to the mounting base, and the other end is rotatably connected to the middle of the swing-wing connecting rod; the mounting base is provided with an irregularly shaped limiting block, and the ends of the first and second support connecting rods connected to the mounting base are respectively located on both sides of the irregularly shaped limiting block; the first support connecting rod is rotatably connected to the mounting base by a solid rivet; a square locking block is provided at the lower end of the solid rivet to fix and engage with the mounting base.

[0005] Specifically, the irregularly shaped limiting block is provided with a first limiting card interface and a second limiting card interface on both sides, and the first limiting card interface and the second limiting card interface respectively limit the engagement of the first support link and the end of the second support link that is rotatably connected to the mounting base.

[0006] Specifically, both the first and second limit card interfaces consist of at least two non-smoothly connected arc-shaped or straight sections.

[0007] Specifically, the mounting base is provided with a sliding groove that is slidably connected to the slider on the sliding support rod, and limit blocks are provided at both ends of the sliding groove.

[0008] Specifically, both the slide and the slider are made of aluminum alloy.

[0009] Specifically, the slider has an "I" shaped cross-section and is equipped with fastening screws. By tightening the fastening screws, the lower end of the fastening screws can pass through the slider and abut against the groove.

[0010] The beneficial effects of this invention are as follows: 1. By setting a non-standard limiting block at the end where the shorter first and second support rods connect to the mounting base, accurate limiting of the swing hinge during the opening and closing process can be achieved, thus improving operational precision. 2. The first support link connected to the mounting tie rod is connected to the mounting base by a solid rivet with a square locking block, which effectively improves the stability of the hinge structure; 3. The use of high-strength aluminum alloy material to connect the sliding support rod and the mounting base with a sliding groove and a slider can improve the smoothness of the hinge opening and closing process and the wear resistance of the connection between the slider and the sliding groove.

Detailed Implementation

[0013] Example 1, referring to Figure 1-3 A high-load-bearing and wear-resistant swing-wing hinge includes a mounting base 1, a mounting rod 2, a swing-wing connecting rod 3, a first support connecting rod 4, and a second support connecting rod 5. One end of the first support connecting rod 4 is rotatably connected to the mounting base 1, and the other end is rotatably connected to the rear end of the mounting rod 2. One end of the swing-wing connecting rod 3 is rotatably connected to a slider 31, which is slidably connected to the mounting base 1, and the other end is rotatably connected to the middle of the mounting rod 2. One end of the second support connecting rod 5 is rotatably connected to the mounting base 1, and the other end is rotatably connected to the middle of the swing-wing connecting rod 3. The mounting base 1 is provided with an irregularly shaped limiting block 6, and the ends of the first support connecting rod 4 and the second support connecting rod 5 connected to the mounting base 1 are respectively located on both sides of the irregularly shaped limiting block 6.

[0014] In this embodiment, the mounting base 1 is used to fix the door and window frame, and the mounting rod 2 is used to fix the door and window sash. When opening and closing the door and window sash, the mounting rod 2 is pushed to move outward or inward. When the mounting rod 2 moves in a horizontal position, the end of the sliding support rod 3 connected to the mounting base 1 slides relative to the mounting base 1. The first support rod 4 rotates with the horizontal movement of the mounting rod 2. The position of the end of the first support rod 4 rotatably connected to the mounting base 1 on the mounting base 1 is fixed. The second support rod 5 rotates with the rotation of the sliding support rod 3, which can play an auxiliary support role for the sliding support rod 3. This is because the length of the sliding support rod 3 is relatively long. With the auxiliary support of the second support rod 5, the load-bearing capacity of the hinge can be effectively improved. To improve the connection stability between the first support rod 4 and the second support rod 5 and the mounting base 1, a reinforcing shim is provided on the mounting base 1 for rotatable connection with the first support rod 4 and the second support rod 5. Since the first support rod 4 and the second support rod 5 are connected to the mounting base 1 in close proximity, a non-smooth limiting block 6 is also provided at the center of the reinforcing shim location on the mounting base 1. The ends of the first support rod 4 and the second support rod 5 connected to the mounting base 1 are respectively located on both sides of the non-smooth limiting block 6. The non-smooth limiting block 6 can achieve differentiated limiting of the first support rod 4 and the second support rod 5 at a certain angle. If a conventional smooth arc-shaped limiting block is used, the limiting force is the same regardless of the rotation angle. However, with the non-smooth limiting block 6, a non-smooth limiting interface can be provided at a certain angle (such as when rotating to the middle position), so that the limiting force at that position is smaller than at other positions, thus facilitating accurate positioning of a certain position during the opening and closing of the door and window sash.

[0015] Specifically, in this embodiment, the irregularly shaped limiting block 6 is provided with a first limiting interface 61 and a second limiting interface 62 on both sides. The first limiting interface 61 and the second limiting interface 62 respectively limit and engage the ends of the first supporting connecting rod 4 and the second supporting connecting rod 5 that are rotatably connected to the mounting base 1. Both the first limiting interface 61 and the second limiting interface 62 are composed of at least two non-smoothly connected arc-shaped or straight sections. Taking two non-smoothly connected straight sections as an example, as shown in the figure, the second limiting interface 62 is composed of two non-smoothly connected straight sections. The non-smooth connection means that two adjacent arc-shaped or straight sections intersect at an obtuse angle less than 180°. For the included angle between the arc-shaped sections, the tangent at the intersection of the arc-shaped sections is used as the side of the included angle. For example, at the second limiting interface 62, when the second support link 5 rotates to the intersection of the two straight sections, the limiting force on the second support link 5 at this position is lower than at other positions. During the opening or closing of the door or window sash, the second support link 5 will provide noticeable tactile feedback after rotating to this position, thereby improving the accurate positioning of the opening and closing process of the door or window sash. Similarly, the first limiting interface 61 shown in the attached figure is non-smoothly connected by an arc section and a straight section.

[0016] In a further embodiment, the first support rod 4 is rotatably connected to the mounting base 1 via a solid rivet 7; a square locking block 71 is provided at the lower end of the solid rivet 7 to fix it in place with the mounting base 1. Using a solid rivet 7 with a square locking block 71 to connect the first support rod 4 to the mounting base 1 can effectively improve the stability of the connection between the first support rod 4 and the mounting base 1, and the solid rivet 7 will not rotate when the first support rod 4 rotates, so that the connection between the first support rod 4 and the mounting base 1 has high torsional resistance and is not easy to loosen. This is because the first support rod 4 is directly supported and connected to the mounting rod 2 of the door and window sash, and it needs to withstand a large load, so the connection between the first support rod 4 and the mounting base 1 needs to have higher stability.

[0017] In a further preferred embodiment, the mounting base 1 is provided with a sliding groove 11, which is slidably connected to the slider 31 provided on the sliding support rod 3. Limit blocks are provided at both ends of the sliding groove 11. Both the sliding groove 11 and the slider 31 are made of aluminum alloy. The use of high-hardness aluminum alloy for both the slider 31 and the sliding groove 11 effectively improves the smoothness of the slider 31 sliding within the sliding groove 11, thereby improving the smoothness of the opening and closing process of the door and window sash.

[0018] In addition, the aforementioned slider 31 has an "I"-shaped cross-section, and a fastening screw 32 is provided on the slider 31. By tightening the fastening screw 32, the lower end of the fastening screw 32 can pass through the slider 31 and abut against the slide groove 11. By tightening the fastening screw 32 downward to abut against the slide groove 11, the slider 31 can be fixed on the slide groove 11, thereby fixing the position of the door and window sash. To avoid wear on the bottom of the slide groove 11 caused by the fastening screw 32, a washer can be placed at the lower end of the fastening screw 32, and the washer abuts against the bottom of the slide groove 11.

[0019] Of course, the above are only preferred embodiments of the present invention and are not intended to limit the scope of application of the present invention. Therefore, any equivalent changes made to the principle of the present invention should be included within the protection scope of the present invention.
