Technical Field
[0001] This utility model relates to the field of hardware technology, and in particular to a window sliding support structure. Background Technology
[0002] A sliding support is a linkage-type movable hinge device used to connect a window sash to a window frame. Its main function is to support the opening and closing of the window and bear the weight of the window sash. Existing sliding supports on the market, when installed in outward-opening windows with European standard 20-groove profiles, are subject to structural limitations. This necessitates milling off the frame edge profile, increasing costs, or the sliding groove is made too narrow, resulting in low load-bearing capacity. Patent application CN107605286B discloses a sliding support comprising: a slide rail, fixed to the window frame by fasteners, the slide rail having a first end and a second end, a slide groove, the bottom surface of the slide groove having a sliding area and a fixed area, the fixed area having a connecting hole for installing fasteners; a first slider, located within the slide groove and slidably mounted on the sliding area; a second slider, located within the slide groove and between the first slider and the second end of the rail, the second slider having a clearance cavity allowing fasteners to pass through; a synchronizing plate, connecting the first slider and the second slider, and a linkage mechanism connecting the window sash, the linkage mechanism hinged to the first slider and the second slider. The overall load-bearing capacity of the skid is not strong, and it lacks adjustment functionality. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a practical, reliable, and load-bearing window sliding support structure.
[0004] To achieve the above objectives, the present invention provides the following solution: a window sliding support structure, comprising a base, a first connecting rod, a second connecting rod, a third connecting rod, a connecting piece, and a first slider. The top of the base has a first sliding groove extending along the length of the base. The first slider slides within the first sliding groove. A second sliding groove is formed on the first slider. One end of the first connecting rod is hinged to the base, and the other end of the first connecting rod is hinged to the middle of the connecting piece. One end of the second connecting rod is hinged to the first connecting rod, and the other end of the second connecting rod is hinged to a sliding member. The second connecting rod and the third connecting rod are hinged to each other. One end of the third connecting rod is hinged to the first slider, and the other end of the third connecting rod is hinged to the end of the connecting piece. The sliding member slides closer to or further away from the hinge between the third connecting rod and the first slider.
[0005] The beneficial effects of this utility model are as follows: it improves the overall load-bearing capacity. The structure is composed of a first connecting rod, a second connecting rod, a third connecting rod, and a first slider to form a connecting sliding mechanism. The third connecting rod is the main bearing connecting rod, and the third connecting rod is hinged to the second connecting rod to form a support point, thereby improving the load-bearing capacity of the third connecting rod. This achieves a force-bearing method similar to a hinge shaft, which greatly improves the load-bearing performance of the sliding support structure. The overall structure is practical and reliable.
[0006] Furthermore, a tail fixing block is riveted into the first sliding groove, and the tail fixing block is hinged to the end of the first connecting rod.
[0007] Furthermore, the tail fixing block has a connecting part formed by bending and arching in the middle, and the connecting part is hinged to the end of the first connecting rod.
[0008] Furthermore, a tail pad is provided between the connecting part and the first connecting rod.
[0009] Furthermore, a positioning block is formed at the bottom of the tail pad, and a positioning groove is opened at the top of the connecting part. When the tail pad is placed on the connecting part, the positioning block is inserted downward into the positioning groove.
[0010] Furthermore, one end of the tail fixing block has a first limiting hole, and the other end of the tail fixing block has a second limiting hole. The bottom of the first sliding groove is respectively formed with a first limiting block and a second limiting block. When the tail fixing block is positioned within the first sliding groove, the first limiting block is inserted upwards into the first limiting hole, and the second limiting block is inserted upwards into the second limiting hole. This invention, by adopting the above structure, improves the stability of the connection between the base and the first connecting rod.
[0011] Furthermore, the bottom of the first sliding groove has multiple adjustment holes, one of which is connected to an angle limiting block. The first slider abuts against the angle limiting block to limit its movement. With the above structure, the maximum opening range of the sliding support can be adjusted by connecting different adjustment holes to the angle limiting block.
[0012] Furthermore, the second connecting rod has a clearance groove on its side wall. When the sliding support is folded up, the hinge between the third connecting rod and the first slider is located within the clearance groove. With the above structure, this invention avoids the hinge between the third connecting rod and the first slider during folding, ensuring smooth folding and achieving complete folding without causing the second connecting rod to protrude.
[0013] Furthermore, a protective cover is slidably provided on the top of the base, the protective cover covers the first slider, and a second sliding groove is opened on the protective cover. The second sliding groove extends along the length direction of the protective cover, and the slider slides in the second sliding groove.
[0014] Furthermore, a first reinforcing groove is formed at the bottom of the first slider, extending along the length of the first slider, and a first reinforcing block is disposed within the first reinforcing groove. By adopting the above structure, this utility model improves the overall stability of the first slider.
[0015] Furthermore, an adjusting screw is connected between the first slider and the protective cover.

With the above structure, the connecting piece is connected to the window sash profile through the Euler groove locking block, and the connecting piece, Euler groove locking block, eccentric shaft, and set screw can realize the up and down adjustment function of the connecting piece and improve the load-bearing performance of the sliding support.
[0017] Furthermore, the first slider has a third sliding groove that extends vertically through the first slider and the third sliding groove extends along the length direction of the first slider. The first reinforcing block has a fourth sliding groove that extends vertically through the first reinforcing block and the fourth sliding groove extends along the length direction of the first reinforcing block. The second sliding groove, the third sliding groove, and the fourth sliding groove are opposite each other from top to bottom, and the sliding member slides in the second sliding groove, the third sliding groove, and the fourth sliding groove respectively.
[0018] Furthermore, the sliding component includes a rivet and a washer. The washer is disposed at the bottom of the first reinforcing block. The rivet passes through the second connecting rod, the second sliding groove, the third sliding groove, and the fourth sliding groove in sequence before connecting to the washer.
[0019] Furthermore, a second slider slides within the first sliding groove, with the first slider and the second slider spaced apart from each other, and the sliding member hinged to the second slider.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example 1:
[0036] See appendix Figure 1 To be continued Figure 8 As shown, a window sliding support structure includes a base 1, a first connecting rod 2, a second connecting rod 3, a third connecting rod 4, a connecting piece 5, and a first slider 61. The top of the base 1 has a first sliding groove 11, which extends along the length of the base 1. The first slider 61 slides within the first sliding groove 11. The first slider 61 has a second sliding groove 71. One end of the first connecting rod 2 is hinged to the base 1, and the other end of the first connecting rod 2 is hinged to the middle of the connecting piece 5. One end of the second connecting rod 3 is hinged to the first connecting rod 2, and the other end of the second connecting rod 3 is hinged to a slider. The second connecting rod 3 and the third connecting rod 4 are hinged to each other. One end of the third connecting rod 4 is hinged to the first slider 61, and the other end of the third connecting rod 4 is hinged to the end of the connecting piece 5. The slider slides closer to or away from the hinge between the third connecting rod 4 and the first slider 61.
[0037] In this embodiment, a tail fixing block 16 is riveted in the first sliding groove 11, and the tail fixing block 16 is hinged to the end of the first connecting rod 2; specifically, the tail fixing block 16 is bent and arched in the middle to form a connecting part 161, and the connecting part 161 is hinged to the end of the first connecting rod 2.
[0038] In this embodiment, a tail pad 17 is provided between the connecting part 161 and the first connecting rod 2. A positioning block 171 is formed at the bottom of the tail pad 17, and a positioning groove 164 is opened at the top of the connecting part 161. When the tail pad 17 is placed on the connecting part 161, the positioning block 171 is inserted downward into the positioning groove 164.
[0039] In this embodiment, a first limiting hole 162 is opened at one end of the tail fixing block 16, and a second limiting hole 163 is opened at the other end of the tail fixing block 16. A first limiting block 12 and a second limiting block 13 are respectively formed at the bottom of the first sliding groove 11. When the tail fixing block 16 is placed in the first sliding groove 11, the first limiting block 12 is inserted upward into the first limiting hole 162, and the second limiting block 13 is inserted upward into the second limiting hole 163.
[0040] In this embodiment, the bottom of the first sliding groove 11 has multiple adjustment holes 14, one of which is connected to an angle limiting block 15. The first slider 61 abuts against the angle limiting block 15 to limit the movement of the first slider 61. By connecting different adjustment holes 14 to the angle limiting block 15, the maximum opening range of the sliding support in this embodiment can be limited.
[0041] In this embodiment, the connecting piece 5 connects to the window sash profile. Specifically, a groove locking block 51 is provided on the end of the connecting piece 5. The connecting piece 5 is connected to the window sash profile through the groove locking block 51. An eccentric shaft 52 is connected to the end of the third connecting rod 4 and the end of the connecting piece 5. The groove locking block 51 is fitted onto the eccentric shaft 52. A set screw 53 is provided inside the groove locking block 51. By rotating the set screw 53, the connecting piece 5 is pushed to move up and down on the eccentric shaft 52.
[0042] The connecting mechanism consisting of the connecting piece 5, the Euler groove locking block 51, the eccentric shaft 52, and the set screw 53 can improve the load-bearing performance of the sliding support in this embodiment. At the same time, by rotating the set screw 53, the set screw 53 moves up and down. At this time, since the eccentric shaft 52 abuts against and presses the set screw 53, when the set screw 53 moves up and down, it drives the Euler groove locking block 51 to move up and down on the eccentric shaft 52, thereby driving the connecting piece 5 to move up and down, so as to adjust the up and down position of the connecting piece 5.
[0043] In this embodiment, a protective cover 7 is slidably disposed on the top of the base 1, covering the first slider 61. A second sliding groove 71 is opened on the protective cover 7, which extends along the length of the protective cover 7, and the slider slides in the second sliding groove 71.
[0044] In this embodiment, a first reinforcing groove 612 is provided at the bottom of the first slider 61. The first reinforcing groove 612 extends along the length direction of the first slider 61, and a first reinforcing block 63 is provided in the first reinforcing groove 612.
[0045] In this embodiment, an adjusting screw 72 is connected between the first slider 61 and the protective cover 7. By rotating the adjusting screw 72, the distance between the first slider 61 and the protective cover 7 is adjusted, thereby adjusting the friction between the first slider 61 and the base 1 and the friction between the protective cover 7 and the base 1, thereby adjusting the sliding speed of the first slider 61.
[0046] In this embodiment, the first slider 61 has a third sliding groove 611 that extends vertically through the first slider 61 and extends along the length of the first slider 61. The first reinforcing block 63 has a fourth sliding groove 631 that extends vertically through the first reinforcing block 63 and extends along the length of the first reinforcing block 63. The second sliding groove 71, the third sliding groove 611, and the fourth sliding groove 631 are arranged opposite each other from top to bottom. The sliding member slides in the second sliding groove 71, the third sliding groove 611, and the fourth sliding groove 631 respectively. The sliding member includes a rivet 81 and a washer 82. The washer 82 is disposed at the bottom of the first reinforcing block 63. The rivet 81 passes through the second connecting rod 3, the second sliding groove 71, the third sliding groove 611, and the fourth sliding groove 631 in sequence and then connects to the washer 82.
[0047] In this embodiment, the length of the first link 2 is greater than the length of the second link 3, and the length of the second link 3 is greater than the length of the third link 4.
[0048] In this embodiment, the first connecting rod 2 and the tail fixing block 16, the first connecting rod 2 and the connecting piece 5, the second connecting rod 3 and the first connecting rod 2, and the second connecting rod 3 and the third connecting rod 4 are respectively hinged by rivets 81.
[0049] In this embodiment, a washer 82 is provided between the connecting piece 5 and the third connecting rod 4.
[0050] In this embodiment, the usage process is as follows: the window sash is in the closed state, the sliding support of this embodiment is in the folded state, the user pushes the window sash profile to move outward, the window sash profile drives the connecting piece 5 to swing through the Euler groove locking block 51, the connecting piece 5 swings to drive the first connecting rod 2 and the third connecting rod 3 to swing respectively, the first connecting rod 2 rotates axially around the hinge between the first connecting rod 2 and the tail fixing block 16, the first connecting rod 2 swings to drive the second connecting rod 3 to swing, the third connecting rod 3 pushes the first slider 61 to slide, so that the first slider 61 approaches the angle limiting block 15, and then the second connecting rod 3 swings, so that the sliding member connected to the end of the second connecting rod 3 slides in the second sliding groove 71, the third sliding groove 611, and the fourth sliding groove 631, and the sliding member also gradually approaches the angle limiting block 15, but at this time the moving speed of the first slider 61 is greater than that of the sliding member, so that the sliding member gradually moves away from the first slider 61 until the first slider 61 touches and presses against the angle limiting block 15, so that the sliding support and the window sash profile of this embodiment open to the maximum extent.
[0051] In this embodiment, the base 1, the first connecting rod 2, the second connecting rod 3, the third connecting rod 4, and the connecting piece form a linkage sliding mechanism. The second connecting rod 3 can provide a fulcrum for the third connecting rod 4, thereby improving the load-bearing strength of the main load-bearing component, the third connecting rod 4. Example 2:
[0052] The difference between this embodiment and embodiment one is that this embodiment adds a second slider 62, and the first slider 61 does not need to have a third sliding groove 611, and the first fixing block 63 does not need to have a fourth sliding groove 631.
[0053] See appendix Figure 9 To be continued Figure 11 As shown, in this embodiment, a second slider 62 slides in the first sliding groove 11. The first slider 61 and the second slider 62 are spaced apart from each other. The slider is hinged to the second slider 62. A second reinforcing groove 621 is opened at the bottom of the second slider 62. The second reinforcing groove 621 extends along the length of the second slider 62. A second reinforcing block 64 is provided in the second reinforcing groove 621. The slider includes a rivet 81 and a washer 82. The washer 82 is provided at the bottom of the second reinforcing block 64. The rivet 81 passes through the second connecting rod 3, the second slider 62, and the second reinforcing block 64 in sequence and then connects to the washer 82.
[0054] In this embodiment, the usage process is as follows: the window sash is in the closed state, and the sliding support in this embodiment is in the folded state. The user pushes the window sash profile to move outward. The window sash profile drives the connecting piece 5 to swing through the Euler groove locking block 51. The swinging of the connecting piece 5 drives the first connecting rod 2 and the third connecting rod 3 to swing respectively. The first connecting rod 2 rotates axially around the hinge between the first connecting rod 2 and the tail fixing block 16. The swinging of the first connecting rod 2 drives the second connecting rod 3 to swing. The third connecting rod 3 pushes the first slider 61 to slide, so that the first slider 61 approaches the angle limiting block 15. Then the second connecting rod 3 swings, so that the sliding member connected to the end of the second connecting rod 3 slides in the second sliding groove 71. The second slider 62 slides in the first sliding groove 11. The second slider 62 also gradually approaches the angle limiting block 15. However, at this time, the moving speed of the first slider 61 is greater than that of the second slider 62, so that the second slider 62 gradually moves away from the first slider 61 until the first slider 61 touches and presses against the angle limiting block 15, so that the sliding support and the window sash profile in this embodiment open to the maximum extent.
