Description

Technical Field

[0001] The utility model relates to the technical field of building doors and windows, in particular to a casement sliding support which is convenient for adjusting the positioning angle. Background Art

[0002] Casement sliding stays are widely used in outward-opening windows to open and close them. Existing casement sliding stays, depending on the location or space, do not need to be fully extended; they only need to be opened to a certain angle. Therefore, positioning holes are used to control the opening angle of the window sash. However, these positioning holes must be pre-set during production, limiting the opening angle. When space constraints prevent the desired opening angle, the sliding stays must be replaced, which is time-consuming and labor-intensive.

[0003] Based on this, the utility model designs a horizontally opening sliding support which is convenient for adjusting the positioning angle. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. It should be understood that the terms "upper", "middle", "outer", "inner", "lower" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, and therefore cannot be understood as limiting the present invention.

[0021] The accompanying drawings are specific embodiments of the present invention, as shown in FIG. Figures 1-4As shown, the utility model is a casement sliding support that is easy to adjust the positioning angle, including a connecting rod mechanism consisting of a base plate 1, a supporting arm 7, a long suspension 6, a middle suspension 3, a short suspension 2, and a slider 5. The short suspension 2 and the middle suspension 3 are hinged on the base plate 1, the short suspension 2 is hinged to the supporting arm 7, the middle suspension 3 is hinged to the middle section of the long suspension 6, one end of the long suspension 6 is hinged to the middle section of the supporting arm 7, and the other end is hinged to the slider 5. The upper part of the supporting arm 7 is fixed to the bottom of the window sash profile by a fixing piece. A base plate elliptical hole 1.1 is opened on the base plate 1, and the base plate elliptical hole 1.1 is a long slotted hole. The slider 5 is slidably connected to the base plate elliptical hole 1.1, and the base plate elliptical hole 1.1 is close to the connecting rod One side of the mechanism has a bottom plate positioning hole 1.2, which is a waist hole. A positioning block 4 is installed on the bottom plate positioning hole 1.2. The positioning block 4 has a positioning hole 4.1, which is located directly above the bottom plate positioning hole 1.2. The bottom of the positioning block 4 is provided with a boss 4.2, which acts as a limiter. The boss 4.2 is slidably connected to the bottom plate elliptical hole 1.1, so that the positioning block 4 can slide within the bottom plate elliptical hole 1.1, thereby adjusting the actual sliding area length of the slider 5 within the bottom plate elliptical hole 1.1. When one end of the slider 5 touches the positioning block 4, it slides open to the required angle. A fixing is used to pass through the positioning hole 4.1, the bottom plate positioning hole 1.2, and the bottom plate 1 in sequence and fixed to the window frame profile. The two ends of the bottom surface of the bottom plate 1 are riveted with a rotary vane A8 and a rotary vane B9, respectively, for pre-installation of the frame.

[0022] During installation, the base plate 1 is pressed against the notch on the window frame profile, and the rotary vane A8 and the rotary vane B9 are turned with a wrench to clamp the profile to complete the pre-installation of the frame. Insert the support arm 7 into the notch of the window sash profile and fix it with screws to complete the installation of the sash. After the sliding support is adjusted to the appropriate position, fix the base plate 1 and the support arm 7 with the mounting screws. Place the positioning block 4 against the base plate 1, align the positioning hole 4.1 with the base plate positioning hole 1.2, and clamp the boss 4.2 in the base plate elliptical hole 1.1. Pass the mounting screw through the positioning block 4 and fix it to the base plate 1 on the profile. When the sliding support is opened, the slider 5 slides in the base plate elliptical hole 1.1, and finally the slider 5 touches the end of the positioning block 4. Figure 4 The length of L represents the distance from the positioning hole 4.1 to the end of the positioning block 4 near the slider 5. When other angles need to be opened, the positioning block 4 with different L lengths can be replaced.

[0023] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all details in detail, nor do they limit the present invention to specific implementation methods.
