Description

Technical Field

[0001] This utility model relates to the technical field of window frame connectors, and in particular to an adjustable-angle aluminum-plastic composite window frame connector. Background Technology

[0002] Aluminum-plastic composite window frames use aluminum alloy as the skeleton and are covered with an outer plastic cladding, combining high strength with excellent thermal insulation and soundproofing performance. The connectors are core hardware components specifically designed to hinge the window sashes onto the window frame. Hidden inside the profile, they play a crucial role in load-bearing, rotation, and connection. To facilitate user adjustment of the window's opening and closing angle, an adjustable-angle aluminum-plastic composite window frame connector is required.

[0003] Traditional window frame connectors adjust the opening and closing angle of a window by adjusting the position of a limiting block in the window frame track. The limiting block restricts the sliding block, thereby adjusting the opening and closing angle of the window.

[0004] Traditional window frame connectors typically require tools to unscrew screws inside the limit block when adjusting its position. The corresponding screws are then pulled out of the positioning holes in the slide groove, allowing the limit block to slide within the groove and adjust the limit of the slider to achieve angle adjustment. This means that adjusting the limit block requires repeatedly unscrewing screws in a confined space, which is not only cumbersome but also completely dependent on tool operation, resulting in poor adjustment flexibility. Utility Model Content

[0005] Therefore, it is necessary to provide an adjustable-angle aluminum-plastic composite window frame connector to address the problem of poor adjustment flexibility of traditional connectors.

[0006] An adjustable-angle aluminum-plastic composite window frame connector includes: a first connecting rod and a second connecting rod disposed between the window frame and the window sash, wherein the second connecting rod is hinged to the middle of the first connecting rod;

[0007] An adjustment component includes a limiting block disposed in a window frame slide groove, a locking block being slidably connected inside the limiting block, and multiple locking slots corresponding to the locking blocks being disposed in the window frame slide groove.

[0008] In one embodiment, a rotating rod is provided between the limiting block and the locking block, and the bottom end of the rotating rod is rotatably connected to the inner wall of the locking block.

[0009] In one embodiment, two positioning blocks are fixedly connected to the surface of the rotating rod, and the inner wall of the limiting block is provided with a positioning groove corresponding to the positioning block. The positioning groove is formed by splicing two fan-shaped grooves.

[0010] In one embodiment, a drive block is hinged to the inner wall of the rotating rod, and the cross-section of the drive block is "T" shaped.

[0011] In one embodiment, a fixing block is fixedly connected to the upper surface of both ends of the card block, and the cross-section of the fixing block is inverted "L" shape.

[0012] In one embodiment, a limiting rod is provided between the inner walls of the fixing block and the limiting block. The limiting rod is slidably connected to the fixing block, and a spring is sleeved on the surface of the limiting rod. The two ends of the spring are fixedly connected to the inner bottom walls of the fixing block and the limiting block, respectively.

[0013] In one embodiment, a fixing member is installed in the window frame groove, and the first connecting rod is hinged between the fixing member and the window sash.

[0014] In one embodiment, a sliding member is slidably connected in the window frame groove, and the second connecting rod is hinged between the sliding member and the first connecting rod.

[0015] In one embodiment, a connecting block is fixedly connected to the surface of the sliding member, and the connecting block is hinged to the window sash.

[0016] Beneficial effects

[0017] 1. By setting a sliding block inside the limiting block and cooperating with the drive block to make it engage with the slot in the window frame, users are freed from the dependence on special tools when they need to adjust the opening angle of the window. Users only need to lift the drive block with their fingers to quickly complete the setting and change of the opening angle. The operation is intuitive and simple, saving time and effort, improving the flexibility of adjustment and reducing the difficulty of daily maintenance.

[0018] 2. By setting a spring between the inner wall of the locking block and the limiting block, a pulling force is applied to the locking block, thereby improving the stability and convenience of the locking block entering the slot. At the same time, by setting a positioning block on the surface of the rotating rod to cooperate with the positioning groove, the locking block is briefly limited after being pulled out of the slot, allowing the operator to adjust the limiting block with one hand, increasing the convenience of adjusting the connecting parts.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The following is combined Figure 1 - Figure 5 This invention describes an adjustable-angle aluminum-plastic composite window frame connector.

[0029] In one embodiment, an adjustable-angle aluminum-plastic composite window frame connector includes: a first connecting rod 100 and a second connecting rod 110 disposed between the window frame and the window sash, wherein the second connecting rod 110 is hinged to the middle of the first connecting rod 100.

[0030] Adjustment component 400 includes a limiting block 410 disposed in a window frame slide rail, a locking block 411 is slidably connected inside the limiting block 410, and a plurality of locking slots 420 corresponding to the locking block 411 are provided in the window frame slide rail.

[0031] like Figure 3 , Figure 4 and Figure 5As shown, a rotating rod 412 is provided between the limiting block 410 and the locking block 411, and the bottom end of the rotating rod 412 is rotatably connected to the inner wall of the locking block 411. Two positioning blocks 4122 are fixedly connected to the surface of the rotating rod 412. The inner wall of the limiting block 410 has a positioning groove 413 corresponding to the positioning block 4122, and the positioning groove 413 is formed by splicing two fan-shaped grooves. A driving block 4121 is hinged to the inner wall of the rotating rod 412, and the cross-section of the driving block 4121 is "T" shaped. Fixed blocks 4111 are fixedly connected to the upper surfaces of both ends of the locking block 411, and the cross-section of the fixed blocks 4111 is inverted "L" shaped. A limiting rod 4112 is provided between the inner wall of the fixing block 4111 and the limiting block 410. The limiting rod 4112 is slidably connected to the fixing block 4111. A spring 4113 is sleeved on the surface of the limiting rod 4112. The two ends of the spring 4113 are fixedly connected to the inner bottom wall of the fixing block 4111 and the limiting block 410, respectively.

[0032] In this embodiment, the width of the positioning block 4122 is smaller than that of the locking block 411. When the locking block 411 is flush with the positioning block 4122, the locking block 411 can pass directly through the channel through which the positioning block 4122 slides. When the rotating rod 412 is rotated, the positioning block 4122 will be horizontally inserted into the positioning groove 413 along the fan-shaped trajectory of the positioning groove 413. At this time, the positioning block 4122 is located in a chamber on the inner wall of the limiting block 410, and the positioning block 4122 is in contact with the inner wall of the limiting block 410 and cannot move up or down, thereby achieving the effect of limiting the rotating rod 412. After the adjustment of the limiting block 410 is completed, the driving block 4121 is pressed down to make the driving block 4121 fit against the surface of the limiting block 410, thereby reducing the space occupied by the adjustment component 400 and avoiding affecting the normal opening and closing of the window and the angle adjustment.

[0033] It should be noted that this device achieves the effect of convenient adjustment of the limiting block 410 by changing the connection method between the limiting block 410 and the window frame slide rail. Since this device only needs to change the positioning hole in the traditional window frame slide rail to the slot 420, it will not affect the installation of other installation parts. At the same time, all components of this device are located on the inner wall of the window frame. When the window is closed, the sealing strip set on the surface of the window frame can still keep the window sealed. Therefore, the adjustment component 400 of this device will not affect the normal use of the window.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, a fixing member 300 is installed in the window frame track, and a first connecting rod 100 is hinged between the fixing member 300 and the window sash. A sliding member 200 is slidably connected in the window frame track, and a second connecting rod 110 is hinged between the sliding member 200 and the first connecting rod 100. A connecting block 210 is fixedly connected to the surface of the sliding member 200, and the connecting block 210 is hinged to the window sash.

[0035] In this embodiment, when the window is opened, by pushing the window sash, the upper and lower ends of the window sash will rotate along the protrusions on the surface of the connecting block 210, and drive the connecting block 210 to push the slider 200, so that the slider moves towards the middle position of the window frame groove. As the slider 200 moves towards the middle of the window frame groove, the window will gradually increase its opening angle. The function of the limiting block 410 is to limit the distance that the slider 200 moves, thereby achieving the effect of adjusting the opening angle of the window. Window frame grooves are provided on the inner walls of both the upper and lower ends of the window frame.

[0036] Working principle: When it is necessary to reduce the opening angle of the window, the user directly pulls the drive block 4121 upwards. The drive block 4121 drives the rotating rod 412 and the locking block 411 to move upwards, causing the locking block 411 to disengage from the slot 420. When the positioning block 4122 moves upwards to the position of the positioning groove 413, the locking block 411 completely disengages from the slot 420, and the rotating rod 412 cannot move further upwards due to the contact between the positioning block 4122 and the inner wall of the limiting block 410. Then, the positioning block 4122 is rotated clockwise, causing the positioning block 4122 to engage in the positioning groove 413. At the same time, the fixing block 4111 moves synchronously, causing the spring 4113 to be in a position... With the tension set, the limiting block 410 can be moved closer to the sliding member 200. After moving it to the appropriate position, the drive block 4121 is rotated counterclockwise. The drive block 4121 drives the rotating rod 412 and the positioning block 4122 to rotate, so that the positioning block 4122 rotates to a state parallel to the locking block 411. Then, the position of the limiting block 410 is adjusted slightly until the locking block 411 is aligned with the slot 420. At this time, the locking block 411 pulls the fixing block 4111 into the slot 420 through the spring 4113, completing the adjustment. Then, the drive block 4121 is pressed down to fit against the upper surface of the limiting block 410.

[0037] When it is necessary to increase the window opening angle, the limiting block 410 can be adjusted to a position away from the sliding member 200 by the above operation.

[0038] It should be noted that the first connecting rod 100, the second connecting rod 110, the sliding member 200, the connecting rod, and the fixing member 300 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
