Description

Technical Field

[0001] This utility model relates to the field of window accessories technology, specifically to an installation structure for the end cap and outer shell of a window opener. Background Technology

[0002] A window opener is a mechanical device used to automatically or manually open and close windows. It is widely used in high-mounted windows, skylights, heavy-duty windows, or building environments with high requirements for airtightness, to solve the problem of time-consuming and laborious opening and closing caused by high window positions and limited operating space.

[0003] Currently, the main methods for fixing the end caps of window openers to their outer shells are screw fastening, pin connection, or direct pressure marks. For example, Chinese utility model patent (application number CN202322177772.X) discloses a window opener structure fixed by screws. However, these fixing methods all have the following drawbacks: they inevitably leave exposed screw heads, pin holes, or pressure marks on the visible surface of the window opener's outer shell. This compromises the integrity and aesthetics of the product surface, making it difficult to meet the aesthetic requirements of high-end doors and windows for "concealed installation" and "no visible screws" for hardware.

[0004] In addition, the existing single-screw fixing method requires the same screw to perform both tightening and fixing functions at the same time. This makes the operation more difficult during assembly, requires high precision, and is prone to deformation of the shell or end cover due to stress concentration, which affects the reliability of long-term use. Utility Model Content

[0005] In view of this, the present invention provides an installation structure for the end cap and the outer shell of a window opener, which ensures that the connection between the end cap and the outer shell has sufficient mechanical strength while avoiding the fastening components being exposed on the visible surface of the outer shell.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An installation structure for an end cap and housing of a window opener includes a housing and end caps located at both ends of the housing, as well as a pressing screw and a fixing screw. Each end cap has two connecting portions fixedly spaced on its inner sidewall facing the housing. The two connecting portions of the same end cap have coaxial first connecting holes. The back of the housing, away from the visible side of the interior, has a second connecting hole corresponding to each connecting portion, and the second connecting hole is coaxial with the corresponding first connecting hole. The shank of the pressing screw is screwed into the first connecting hole away from the second connecting hole, and its end is pressed against the inner wall of the housing by tightening. The shank of the fixing screw passes sequentially through the second connecting hole and the first connecting hole near the second connecting hole, and is threadedly connected to the first connecting hole, with the head of the fixing screw pressing against the wall of the second connecting hole.

[0008] To better achieve the above technical solution, optionally, the opposite sidewalls of the two connecting parts of the same end cap may contact the inner wall of the outer shell.

[0009] Optionally, adhesive is provided between the pressing screw and the fixing screw.

[0010] Optionally, the fixing screw is provided with a fixing adhesive on the wall of the second connecting hole and the mating surface of the first connecting hole near the second connecting hole.

[0011] Optionally, the second connecting hole is a conical hole, and the head of the fixing screw is a conical structure adapted to the conical hole.

[0012] The beneficial effects of this utility model are:

[0013] The installation structure of the end cap and outer shell of this utility model for the window opener allows for concealed installation of the fixing screws. When the window opener is an outward-opening window, the second connecting hole is located on the surface of the outer shell where the chain plate is mounted, i.e., on the back of the outer shell. When the window opener is an inward-opening window, the second connecting hole is located on the back of the outer shell where the chain plate is mounted. Both installation methods enable concealed installation of the fixing screws, preventing them from being visible from inside the room and improving the neatness and aesthetics of the window opener's appearance.

[0014] The installation structure of the end cap and outer shell of this utility model window opener, through the functional division of the top pressing screw and the fixing screw, breaks down the traditional single screw fixing positioning and fastening synchronous operation into a step-by-step operation, which improves the fault tolerance of assembly and reduces the skill requirements of operators.

[0023] The outer casing 10, the second connecting hole 101, the end cap 20, the connecting part 21, the first connecting hole 211, the top pressing screw 30, the fixing screw 40, and the chain disc 50. Detailed Implementation

[0024] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. Identical components are indicated by the same reference numerals.

[0025] Please see Figures 1 to 7 This utility model discloses an installation structure for the end cap and outer shell of a window opener, including an outer shell 10, an end cap 20, a pressing screw 30, and a fixing screw 40. The two ends of the outer shell 10 are open ends. There are two end caps 20, which are respectively disposed at the two ends of the outer shell 10. The pressing screw 30 and the fixing screw 40 are used to realize the fixed connection between the outer shell 10 and the end cap 20.

[0026] Specifically, two connecting portions 21 are fixedly provided at intervals on the opposite sidewalls of the two end caps 20. The two connecting portions 21 of the same end cap 20 are provided with coaxial first connecting holes 211. The back of the outer shell 10 is provided with a second connecting hole 101 corresponding to the position of each connecting portion 21. The second connecting hole 101 is coaxial with the corresponding first connecting hole 211. The shank of the pressing screw 30 is screwed into the first connecting hole 211 away from the second connecting hole 101, and its end is pressed against the inner wall of the outer shell 10 by tightening, forming a radial preload. The shank of the fixing screw 40 passes through the second connecting hole 101 and the first connecting hole 211 near the second connecting hole 101 in sequence, and is threadedly connected to the first connecting hole 211. The head of the fixing screw 40 is pressed against the hole wall of the second connecting hole 101.

[0027] like Figure 2 As shown, in an embodiment of this utility model, when the window opener is an outward-opening window, the second connecting hole 101 is opened on the surface of the outer casing 10 where the chain plate 50 is located, i.e., the back side of the outer casing 10. Figure 7 As shown, when the window opener is an inward-opening window, the second connecting hole 101 is opened on the back of the chain plate 50 on the outer casing 10. Both settings can achieve the concealed installation of the fixing screw 40, avoiding the exposure of the fixing screw 40 from the inside, and improving the cleanliness and aesthetics of the window opener.

[0028] Please see Figure 6The installation method in this embodiment is as follows: Before the end cap 20 is fitted into the end of the outer shell 10, the shank of the pressing screw 30 is pre-screwed into the first connecting hole 211. Then, the end cap 20 is fitted into the end of the outer shell 10 axially, so that the connecting part 21 fits against the inner wall of the outer shell 10. An adapter tool is inserted into the second connecting hole 101 and the adjacent first connecting hole 211, and the head of the pressing screw 30 is rotated and tightened until the shank of the pressing screw 30 forms a stable frictional force with the inner wall of the outer shell 10. Finally, the fixing screw 40 is passed through the second connecting hole 101 and the corresponding first connecting hole 211 in sequence and tightened until the head fits against the inner wall of the second connecting hole 101. In this installation process, the functional division of the pressing screw 30 and the fixing screw 40 breaks down the traditional single screw fixing positioning and tightening synchronous operation into a step-by-step operation, which improves the fault tolerance of the assembly and reduces the skill requirements of the operator.

[0029] In the embodiments of this utility model, the opposite sidewalls of the two connecting parts 21 of the same end cap 20 are respectively attached to the inner wall surface of the outer shell 10. This structure makes the connecting parts 21 and the outer shell 10 form a surface contact, which can not only limit the radial displacement of the connecting parts 21 through the inner wall of the outer shell 10, but also play an automatic positioning role during assembly, improving the smoothness of screw assembly.

[0030] In this embodiment of the utility model, a fixing adhesive is provided between the pressing screw 30 and the fixing screw 40. The fixing adhesive is provided at this position, and after the fixing adhesive cures, it can connect the pressing screw 30 and the fixing screw 40 into one piece, avoiding relative loosening caused by vibration during long-term use. The fixing screw 40 is provided with fixing adhesive on the hole wall of the second connecting hole 101 and the mating surface of the first connecting hole 211 near the second connecting hole 101. After the adhesive layer cures in the thread gap, it can generate a lasting anti-loosening torque, effectively solving the problem of reverse loosening of the fixing screw 40 under long-term opening and closing vibration environment.

[0031] In an embodiment of this utility model, the second connecting hole 101 is a conical hole, and the head of the fixing screw 40 is a conical structure adapted to the conical hole. The use of an adapted structure can improve the stability of the connection.

[0032] The technical solution of this utility model has been described in detail above with reference to specific embodiments. The specific embodiments described are used to help understand the concept of this utility model. Derivations and modifications made by those skilled in the art based on the specific embodiments of this utility model also fall within the protection scope of this utility model.
