Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of window material structures, in particular to a swing pulley limiting structure. Background Art
[0002] At present, the windows of houses include casement windows, tilt-down windows and sliding windows. These windows have their own advantages, but they all have certain defects. For example, casement windows are difficult to use due to the narrow space outside the window and the problem of being blocked by objects; sliding windows mostly use double grooves and double slide rails. Since the two windows are not in the same vertical plane, there is a gap between the two windows when the window sashes are closed, and outdoor dust can easily enter the room. Due to the poor sealing of the two windows, the indoor sound insulation effect is poor, and the indoor thermal insulation performance is affected. The tilt-down window has a small opening area and poor ventilation effect. A sliding tilt-down window that combines a tilt-down window and a sliding window takes into account the advantages of the tilt-down window and the sliding window, and can adopt two opening methods according to needs.
[0003] Sliding and tilting windows are all equipped with a misoperation simulation function. In many cases, improper operation requires manual resetting, and many owners do not know how to restore the windows to the correct state. Utility Model Content
[0004] In order to solve the above-mentioned problem that the sliding inward tilting window is prone to misoperation and needs manual resetting after misoperation, the utility model provides a swing pulley limiting structure.
[0005] In order to achieve the above functions, the technical solution adopted by the utility model is as follows: a swing pulley limiting structure, including a pulley, a swing arm, a swing arm seat, a transmission rod and a positioning piece, the pulley is provided with wheels, the pulley is hinged with a limiting piece, one end of the swing arm is hinged to the pulley, and the other end of the swing arm is hinged to the swing arm seat through a rotating shaft, the rotating shaft can rotate 0-90, the positioning piece is provided with a swing piece, and the swing piece is provided with a torsion spring.
[0006] In a preferred technical solution of the utility model, a toggle piece is arranged inside the transmission rod, and a compression spring is arranged inside the toggle piece.
[0007] In a preferred technical solution of the utility model, concave and convex points are arranged on the swinging member.
[0008] Compared with the prior art, the utility model adopts the above structure to achieve the following beneficial effects:
[0009] 1. The self-resetting swing and toggle parts can improve the window operation and prevent it from opening by mistake. There is no need to reset it manually. The torsion spring of the swing can reset itself.
[0010] 2. Through the concave and convex points on the swing part, the movement of the driving rod and the left and right movement of the concave and convex points of the swing part can move the swing part. When the window sash is opened, the toggle part is away from the swing part and resets itself under the action of the torsion spring. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] In the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. The present utility model is further described in detail below in conjunction with the accompanying drawings.
[0021] like Figure 1-7 As shown, the utility model provides a swing pulley limiting structure, including a pulley 03, a swing arm 031, a swing arm seat 032, a transmission rod 02 and a positioning member 01, the pulley 03 is provided with a wheel 03A, the pulley 03 is hinged with a limiting member 03B, one end of the swing arm 031 is hinged to the pulley 03, the other end of the swing arm 031 is hinged to the swing arm seat 032 through a rotating shaft 033, the rotating shaft 033 can rotate 0-90, the positioning member 01 is provided with a swing member 011, the swing member 011 is provided with a torsion spring 012, the transmission rod 02 is provided with a toggle member 021, the toggle member 021 is provided with a compression spring 023, and concave and convex points are provided on the swing member 011.
