Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window accessories technology, specifically to a novel lifting push-pull pulley structure. Background Technology
[0002] Existing pulleys generate significant friction during lifting and lowering, resulting in increased force required to open and close doors and windows, making operation of the main body of doors and windows time-consuming, laborious, and not smooth. Solving these problems is the challenge addressed by this invention. Utility Model Content
[0003] This utility model provides a novel lifting and pushing pulley structure. By adopting the lifting and pushing pulley structure of this utility model, the friction force during lifting and lowering can be effectively reduced, the operation difficulty can be greatly reduced, and the main body of the door and window can be operated smoothly.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A novel lifting and pushing pulley structure includes a pulley body, on which a lifting and lowering part and a sequential part are configured. The lifting and lowering part includes a first guard plate and a second guard plate, and a connecting shaft is provided between the first guard plate and the second guard plate. A bearing or bushing is configured on the connecting shaft. Beneficial effects
[0006] The lifting and pushing pulley structure of this utility model can effectively reduce the friction during lifting and lowering, greatly reducing the difficulty of operation and allowing for smooth operation of the door and window body. Attached Figure Description
[0007] Figure 1 This is a schematic diagram of the overall assembly structure of a specific embodiment of the lifting push-pull pulley structure of this utility model;
[0008] Figure 2 for Figure 1 A schematic diagram of the decomposed structure;
[0009] Among them, 10 is the pulley body; 11 is the lifting and lowering part; 12 is the alignment part; 13 is the first guard plate; 14 is the second guard plate; 15 is the connecting shaft; and 16 is the bushing. Detailed Implementation
[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0011] Example 1:
[0012] refer to Figure 1-2 The image shows a specific embodiment of a novel lifting and pushing pulley structure of this utility model, including a pulley body 10, a lifting and lowering part 11 and a aligning part 12 disposed on the pulley body 10, the lifting and lowering part 11 including a first guard plate 13 and a second guard plate 14, a connecting shaft 15 disposed between the first guard plate 13 and the second guard plate 14, and a bushing 16 disposed on the connecting shaft 15. By disposing of a bushing on the connecting shaft 15, the opening and closing forces of the doors and windows are effectively reduced, greatly reducing the difficulty of operating the doors and windows.
[0013] Alternatively, a bearing can be configured on the connecting shaft 15 to achieve the same effect.
[0014] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
