[0002] With the continuous change of scene requirements, people have different requirements for the opening angle of window sashes. The existing products on the market have a fixed opening angle, and the products can only meet the installation of one type of window, making it difficult to adapt and unable to meet the universality of the scene. The overlapping amounts of window profiles are also different, and the products cannot be adjusted. Only different products can be used for installation, with a wide variety, and the overall stability of the window cannot be guaranteed. Summary of the Invention
[0003] Aiming at the deficiencies of the existing technology, the present invention provides a three-dimensionally adjustable and multi-angle universal lower hinge device, which can adapt to various profiles on the market, can realize multi-angle adjustment according to the use scenario, meet the needs of most customers in the market, and is suitable for wide promotion and application.
[0004] The present invention is realized through the following technical solutions: Provide a three-dimensionally adjustable and multi-angle universal lower hinge device, including a bottom plate, a movable plate A, a movable plate B, and an L-shaped fan member. Installation counterbores are respectively opened at both ends of the bottom plate, a sliding groove and a guiding sliding groove penetrating the bottom plate are respectively opened between the two installation counterbores, an adjustment counterbore is opened between the sliding groove and the guiding sliding groove on the bottom plate, and an adjustment nail is arranged in the adjustment counterbore. Clamping pieces are respectively arranged below both ends of the bottom plate corresponding to the installation counterbores, and are fixedly installed in the window frame groove through tightening nails. An adjustment plate is arranged below the bottom plate under the sliding groove and the adjustment counterbore, and a slider slidably connected with the guiding sliding groove is arranged in the guiding sliding groove under the bottom plate. One end of the movable plate A is movably connected with the slider through an eccentric nail penetrating the guiding sliding groove, and the other end of the movable plate A is hinged to the vertical plate of the L-shaped fan member through a hinge shaft. One end of the movable plate B is riveted to one end of the adjustment plate through a fixed rivet column penetrating the sliding groove, the other end of the movable plate B is hinged to the horizontal plate of the L-shaped fan member through a swing arm plate, and the other end of the adjustment plate is fixedly connected with the adjustment nail in the adjustment counterbore.
[0005] In this solution, the bottom plate and the L-shaped fan member are respectively connected to the window sash and the window frame. Through the cooperation of the movable plate A, the movable plate B, the adjustment nail and the eccentric nail with the bottom plate, the adjustment nail can be rotated by a wrench to drive the movement of the adjustment plate, thereby driving the change of the position of the movable plate B, realizing the left-right adjustment of the window sash, and at the same time adjusting the opening angle of the window sash. By rotating the eccentric nail with a wrench, the window sash can be moved in the indoor and outdoor directions to adjust the sealing of the window sash. By rotating the set screw with a wrench to press against the hinge shaft, the threaded drive causes the fan member to shift up and down, realizing the up-down adjustment of the window sash, and thus realizing the three-dimensional adjustment of the lower hinge device to adapt to various profiles on the market.
[0006] Furthermore, on one side of the vertical plate of the L-shaped fan piece, a threaded barrel with both ends open and inserted and matched with the hinge shaft is vertically fixed. At the upper end of the threaded barrel, a set screw is threadedly connected within its opening. On the upper end face of the set screw, a polygonal hole groove is recessed, which can cooperate with a wrench to rotate it.
[0007] By rotating the set screw with a wrench, it can press against the hinge shaft, and the thread drives the L-shaped fan piece to move up and down, for realizing the up and down adjustment of the window sash.
[0008] Preferably, a positioning block which is slidably connected with the guiding chute and used for abutting and limiting the slider is further arranged in the guiding chute under the bottom plate.
[0009] The positioning block is clamped in the guiding chute on the bottom plate, for limiting the moving distance of the slider, and further limiting the opening angle of the window sash. Installing the positioning block according to the scene requirements can realize the conversion between 90° and 180° rotation.
[0010] Furthermore, the movable plate A is arranged above the movable plate B and the two are hinged in an X shape.
[0011] Furthermore, convex platforms for limiting the clamping pieces downward are respectively formed at both ends of the bottom plate.
[0012] The clamping pieces are fixed on the tightening screws. The convex platforms are arranged at both ends of the bottom plate to play a role in limiting the clamping pieces, which is convenient for the clamping pieces to lock the profile frame notch, clamp the profile, and make the installation more firm.
[0013] Furthermore, a fan clamping piece is rotationally installed at the end of the cross plate of the L-shaped fan piece by press riveting.
[0014] The fan clamping piece is rotationally riveted at the end of the cross plate of the L-shaped fan piece. It can be clamped and positioned with the notch through the fan clamping piece, which is convenient for installation.
[0015] Furthermore, a polygonal hole groove which can cooperate with a wrench to adjust its angle is formed on the surface of the fan clamping piece.
[0016] A polygonal hole groove is formed in the middle of the surface of the fan clamping piece. Rotate the fan clamping piece with a wrench to clamp the profile fan notch, which is convenient for installation and fixation.
[0017] The beneficial effects of the present invention: In the present invention, the bottom plate and the L-shaped fan member are respectively connected to the window sash and the window frame. By means of the cooperation of the movable plate A, the movable plate B, the adjusting nail and the eccentric nail with the bottom plate, the adjusting nail can be rotated by a wrench to drive the adjusting plate to move, and then drive the position change of the movable plate B, so as to realize the left and right adjustment of the window sash. At the same time, the opening angle of the window sash is adjusted. By rotating the eccentric nail with a wrench, the window sash can be moved in the indoor and outdoor directions to adjust the sealing of the window sash. By rotating the set screw with a wrench to press against the hinge shaft, the threaded drive type fan member is offset up and down, so as to realize the up and down adjustment of the window sash, and further realize the three-dimensional adjustability of the lower hinge device, which is adapted to a variety of profiles on the market.
[0018] The structure of the present invention is simple and the installation is fast. The three-dimensional adjustability of the lower hinge device can be adapted to a variety of profiles on the market. According to the use scenario, multi-angle adjustment can be realized to meet the needs of most customers in the market, and it is suitable for wide promotion and application.
