[0020] like Figure 1 and Figure 2As shown, the present invention discloses a sliding support structure with strong load-bearing capacity, comprising a fixed arm 1, a movable arm 2, a main load-bearing arm 3, a secondary load-bearing arm 4, a first connecting rod 5, and a second connecting rod 6. The two ends of the main load-bearing arm 3 are respectively hinged to the middle of the fixed arm 1 and one end of the movable arm 2. One end of the secondary load-bearing arm 4 is slidably connected to one end of the fixed arm 1, and the middle of the secondary load-bearing arm 4 is hinged to the middle of the main load-bearing arm 3. The secondary load-bearing arm 4 is also capable of reciprocating sliding away from the hinge point between the main load-bearing arm 3 and the fixed arm 1. One end of the first connecting rod 5 is slidably connected to the other end of the fixed arm 1, and the first connecting rod 5 is also capable of reciprocating sliding away from the main load-bearing arm. 3. The reciprocating sliding at the hinge of the fixed arm 1, one end of the second link 6 is hinged to one end of the movable arm 2, and the hinge of the second link 6 and the movable arm 2 is closer to the middle of the movable arm 2 than the hinge of the main load-bearing arm 3 and the movable arm 2. The other end of the second link 6 is hinged to the other end of the first link 5 and the other end of the second link 6 is hinged to the other end of the auxiliary load-bearing arm 4, and the hinge of the second link 6 and the auxiliary load-bearing arm 4 is closer to the middle of the second link 6 than the hinge of the second link 6 and the first link 5. The hinge of the second link 6 and the auxiliary load-bearing arm 4 is also closer to the main load-bearing arm 3 than the hinge of the second link 6 and the first link 5.

[0021] In this sliding support structure, the cross-hinged connection between the main load-bearing arm 3 and the secondary load-bearing arm 4 not only strengthens each other but also reliably restricts and strengthens the first link 5 and the second link 6. This facilitates a more stable and reliable load-bearing effect, enabling the sliding support to have a very strong load-bearing capacity. It can provide stable and reliable support and positioning for heavy door and window sashes for a long time, and it is not prone to deformation or damage even after long-term use. This not only helps to extend the service life of the sliding support and the door and window but also greatly improves the safety of door and window use.

[0022] By hinged one end of the main load-bearing arm 3 to the middle of the fixed arm 1, and slidably connecting one end of the secondary load-bearing arm 4 and one end of the first connecting rod 5 to the two ends of the fixed arm 1 respectively, and connecting the second connecting rod 6 to the movable arm 2, the first connecting rod 5, and the secondary load-bearing arm 4, an accurate and stable limiting effect can be achieved, thereby making the movement of the sliding support very accurate and stable. This gives the sliding support structure a very high degree of reliability and applicability.

[0023] like Figure 1 and Figure 2As shown, the two ends of the main load-bearing arm 3 are respectively placed on the top of the fixed arm 1 and the bottom of the movable arm 2. One end of the secondary load-bearing arm 4 and one end of the first connecting rod 5 are both placed on the top surface of the fixed arm 1. The middle part of the main load-bearing arm 3 overlaps on the top surface of the secondary load-bearing arm 4. One end of the second connecting rod 6 is placed on the bottom surface of the movable arm 2, and the other end of the second connecting rod 6 is placed on the top surface of the first connecting rod 5 and the top surface of the secondary load-bearing arm 4. This allows for a more compact and stable assembly of the various components of the sliding support structure, thereby facilitating the formation of a stable, reliable, and widely applicable sliding support structure. This helps to further improve the reliability and applicability of the sliding support structure.

[0024] like Figures 1 to 3 As shown, one end of the main load-bearing arm 3 is bent downwards and rests against the top surface of the fixed arm 1. The secondary load-bearing arm 4 has a clearance notch 41 on its side wall facing the hinge point between the main load-bearing arm 3 and the fixed arm 1 to avoid the downward bend of the main load-bearing arm 3. This not only ensures the stability of the hinge of the main load-bearing arm 3 but also facilitates a more compact folding of the sliding support structure, making it suitable for use in narrow doors and windows. This helps to further expand the applicability of the sliding support structure.

[0025] like Figures 1 to 3 As shown, the main load-bearing arm 3 and the second connecting rod 6 have a first clearance notch 10 and a second clearance notch 20 respectively on their opposite side walls. This allows the sliding support to have a more compact structure, thereby further expanding the applicability of the sliding support structure.

[0026] like Figure 1 and Figure 2 As shown, the high-load-bearing sliding support structure also includes a first locking pin 7 and a locking block 8. A guide slot 11 is provided on the fixed arm 1. The small end of the first locking pin 7 passes sequentially through the secondary load-bearing arm 4 and the guide slot 11. The locking block 8 is fitted onto the small end of the first locking pin 7, allowing the secondary load-bearing arm 4 and the locking block 8 to slide and clamp together on the fixed arm 1. This allows one end of the secondary load-bearing arm 4 to be stably slidably connected to the fixed arm 1, thereby improving the accuracy and stability of the sliding of the secondary load-bearing arm 4, and further enhancing the reliability and applicability of the sliding support structure.

[0027] like Figure 1 and Figure 2 As shown, a wear-resistant shell 12 is fastened to the fixed arm 1, and the wear-resistant shell 12 is clamped between the sub-support arm 4 and the fixed arm 1. This improves wear resistance, thereby extending the service life. Furthermore, the fastened wear-resistant shell 12 enhances the structural strength of the fixed arm 1, thus further improving the reliability and applicability of the sliding support structure.

[0028] The wear-resistant shell 12 is made of existing wear-resistant plastic or wear-resistant metal, which can meet the needs of actual manufacturing.

[0029] like Figure 1 As shown, a limiting protrusion 42 for limiting the swing amplitude of the main load-bearing arm 3 is provided on the end of the secondary load-bearing arm 4 near the second connecting rod 6. When the sliding support structure is extended to a certain extent, the main load-bearing arm 3 will be blocked and restricted by the limiting protrusion 42, so that the main load-bearing arm 3 can be accurately positioned in a suitable position, thereby enabling it to be quickly and accurately extended into place, which in turn helps to further improve the applicability of the sliding support structure.

[0030] like Figure 1 and Figure 2 As shown, the fixed arm 1 has a guide hole groove 13, and a sliding seat 9 is embedded in the guide hole groove 13. The first connecting rod 5 is hinged to the sliding seat 9. This facilitates accurate and stable sliding connection of the first connecting rod 5, thereby helping to further improve the reliability and applicability of the sliding support structure.

[0031] like Figure 1 and Figure 2 As shown, in the actual manufacturing process, the guide slot 11 and the guide hole slot 13 can be made into waist-shaped holes, which can achieve a good guiding effect.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, the sliding seat 9 includes an upper clamping block 91, a lower clamping block 92, and a locking screw 93. The guide slot 13 is vertically opened through the fixed arm 1. The upper clamping block 91 and the lower clamping block 92 are slidably arranged on the upper and lower parts of the fixed arm 1, respectively. The threaded end of the locking screw 93 passes through the upper clamping block 91 and the guide slot 13 in sequence and is screwed onto the lower clamping block 92. The first connecting rod 5 is hinged to the upper clamping block 91 and / or the lower clamping block 92. This allows the clamping force of the upper clamping block 91 and the lower clamping block 92 on the fixed arm 1 to be adjusted by tightening or loosening the locking screw 93. This allows for adjustment of the sliding friction of the sliding seat 9 on the fixed arm 1 and the stable locking of the sliding support structure's unfolded state. This facilitates users in adjusting the opening and closing force and wind resistance of doors and windows according to different opening and closing habits, thereby further improving the applicability of the sliding support structure.

[0033] like Figure 2 and Figure 4 As shown, a raised sliding fitting portion 911 is provided on the bottom surface of the upper clamping block 91, and the sliding fitting portion 911 is fitted into the guide hole groove 13. This can further improve the accuracy and stability of the sliding seat 9, thereby helping to further improve the reliability and applicability of the sliding support structure.

[0034] like Figure 1 , Figure 2 and Figure 4 As shown, a second locking pin 94 that can rotate relative to the first connecting rod 5 is inserted through one end, and the small end of the second locking pin 94 passes through the first connecting rod 5, the upper clamping block 91, and the guide hole groove 13 in sequence before locking onto the lower clamping block 92. This allows one end of the first connecting rod 5 to be stably and reliably hinged to the sliding seat 9, thereby helping to further improve the reliability of the sliding support structure.

[0035] like Figure 1 and Figure 2 As shown, the fixed arm 1 is strip-shaped, and the guiding directions of the guide slot 11 and guide groove 13 are both in the same direction as the length direction of the fixed arm 1. This creates a sliding support that is extremely stable when unfolded and folded, thereby helping to further improve the reliability and applicability of the sliding support structure.

[0036] like Figure 1 and Figure 2 As shown, the movable arm 2 includes a lower support strip 21 and an upper support strip 22. One end of the lower support strip 21 is hinged to the main load-bearing arm 3, and the middle part of the lower support strip 21 is hinged to the second connecting rod 6. The upper support strip 22 is fixedly installed on the top of the lower support strip 21. This design gives the movable arm 2 a high-strength structure and allows for quick matching of different upper support strips 22 to create suitable sliding supports for various doors and windows, thereby further improving the reliability and applicability of the sliding support structure.

[0037] In actual installation, the fixed arm 1 is fixed to the door and window frame, and the movable arm 2 is fixed to the door and window sash. There is a sliding support at the top and bottom of the door and window sash, and the two sliding supports are arranged in a mirror symmetrical relationship. In this way, the door and window sash can be limited to the door and window frame by the sliding support structure, and the normal opening and closing needs of the door and window sash can be met.

[0038] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
