Description

Technical Field

[0001] This invention belongs to the field of door and window technology, and in particular relates to a novel method for fixing a rotating swing arm on a drift window track to a profile. Background Technology

[0002] For example, a utility model patent authorized in China discloses a novel drift window track, with publication number CN215369437U, which discloses a technical solution that "includes a frame track and a fan track with the same structure but opposite direction. Both the fan track and the frame track have openings at opposite ends, and the openings are connected to an inner cavity. A convex rail is provided on the side of the inner cavity away from the opening, and inclined rails are provided on both sides of the opening. A first connecting rod is rotatably connected to one side of the frame track, and the first connecting rod is slidably connected to the fan track through a first pulley group. A second pulley group is slidably connected to the other side of the frame track, and the second pulley group is rotatably connected to the fan track through a second connecting rod. Both the first pulley group and the second pulley group include an upper pulley and a lower pulley. The upper pulley slides against the inclined rail through the inclined surface, and the convex rail is embedded in the groove of the lower pulley and slides against each other."

[0003] However, this technical solution uses multiple sets of connecting rods, which increases the complexity of installation. In actual on-site installation, it is difficult for installers to accurately align and fix these connecting rods in parallel, which increases installation time, increases installation difficulty, reduces installation efficiency, and also has the problems of low flexibility and difficulty in pushing and pulling.

[0004] Therefore, the present invention provides a novel method for fixing a rotating swing arm and a profile on a drift window track. Summary of the Invention

[0005] In view of the aforementioned problems with existing technologies, the purpose of this invention is to provide a novel method for fixing the rotating swing arm and the profile on a drift window track. The main objective of this method is to realize a "disassembled parts transportation, on-site assembly" operation model for drift window products, thereby significantly reducing operating costs such as production costs, packaging and transportation costs, and on-site installation costs. A comprehensive cost reduction of over 15% is achievable. Simultaneously, this invention addresses the current technology's use of multiple connecting rods, which increases installation complexity. During actual on-site installation, installers find it difficult to accurately align and parallelly fix these connecting rods, increasing installation time, raising installation difficulty, reducing installation efficiency, and also resulting in low flexibility and laborious pushing and pulling.

[0006] The objective of this invention can be achieved through the following technical solutions: A novel method for fixing a rotating swing arm on a drift window track to a window profile includes a track window frame and a side window frame. A pulley assembly is provided on the track window frame. The pulley assembly is connected to the rotating swing arm. The rotating swing arm is connected to a fixed base via a fixed shaft. The rotating swing arm is then connected to the window sash profile via the fixed base.

[0007] As a further preferred technical solution of the present invention, the window sash profile is provided with a window sash profile track edge, the window sash profile track edge is provided with an opening groove, the outer dimensions of the opening groove are larger than the outer dimensions of the fixed base, an inner track is provided at the bottom of the opening groove, and buckles are also provided at both ends of the opening of the opening groove.

[0008] As a further preferred technical solution of the present invention, the window sash profile is further provided with a window sash profile side, and a groove is provided on the window sash profile side. The fixing base is positioned in the groove on the window sash profile side by means of self-tapping screws.

[0009] As a further preferred technical solution of the present invention, a rectangular keyway is provided on both the left and right sides of the fixed base. The fixed base is engaged with the opening groove on the side of the window sash profile through the rectangular keyway and the fixing key. The fixed base is also provided with a circular stepped through hole. An internal thread is machined in the circular stepped through hole. The fixed base is screwed to the fixed shaft through the internal thread of the circular through hole.

[0010] As a further preferred technical solution of the present invention, the bottom of the fixed base is provided with an isosceles trapezoidal slot, and the fixed base is engaged with the inner track provided at the bottom of the slot of the window sash profile opening through the isosceles trapezoidal slot. The side of the fixed base is also provided with a blind hole, and the fixed base is positioned in the groove on the side of the window sash profile by cooperating with the self-tapping screw through the blind hole.

[0011] As a further preferred technical solution of the present invention, one end of the fixing key is provided with a hook part, the cross-section of the hook part is in the shape of a hook, the hook part is engaged with the buckles provided at both ends of the opening of the opening groove on the side of the window sash profile, the other end of the fixing key is provided with a key body part, the cross-section of the key body part is rectangular, and the key body part is embedded in the rectangular key slots opened on the left and right sides of the fixing base.

[0012] As a further preferred technical solution of the present invention, the pulley block is provided with a threaded hole in the middle, the pulley block is connected to the rotating swing arm through the threaded hole and in conjunction with the fixed shaft, the lower end of the fixed shaft is machined with an external thread, the upper end of the fixed shaft is provided with a regular hexagonal groove in the center, and the external thread of the fixed shaft is screwed into the threaded hole of the pulley block or the internal thread of the circular stepped through hole of the fixed base.

[0013] As a further preferred technical solution of the present invention, the rotating swing arm is provided with an arm body, the left end of the arm body is connected to a first bushing, the right end of the arm body is connected to a second bushing, the rotating swing arm is connected to a pulley block through a fixed shaft inside the first bushing, and the rotating swing arm is connected to the window sash profile through a fixed shaft inside the second bushing and in conjunction with a fixed base.

[0014] As a further preferred technical solution of the present invention, during assembly, the external thread machined at the lower end of the fixed shaft engages with the internal thread of the circular stepped through hole opened in the fixed base. After the external thread machined at the lower end of the fixed shaft passes through the fixed base, it presses against the inner track and lifts the fixed base upward. At the same time, the rectangular keyway of the fixed base engages with the fixed key to restrict the upward movement of the fixed base, thereby forming a fixed and secure relationship between the fixed base and the window sash profile.

[0015] As a further preferred technical solution of the present invention, the method of fixing the rotating arm on the window frame profile is the same as the method of fixing it on the window sash profile, but the shape and size of the fixing base used in the method of fixing the rotating arm on the window frame profile are different from those used in the method of fixing the rotating arm on the window sash profile.

[0016] As described above, the novel method for fixing the rotating swing arm and the profile on a drift window track provided by the present invention has the following beneficial effects: 1. This invention utilizes a novel method for fixing a rotating swing arm to a window profile on a drift window track. Compared with existing technologies, this method not only connects the pulley block and the profile via a rotating swing arm, but also includes a fixed base and a fixed shaft that cooperate with the rotating swing arm. During installation, the external thread machined at the lower end of the fixed shaft engages with the internal thread of a circular stepped through hole in the fixed base. The external thread at the lower end of the fixed shaft passes through the fixed base and presses against the inner track, lifting the fixed base upwards. Simultaneously, the rectangular keyway of the fixed base engages with the fixed key to restrict the upward movement of the fixed base, thereby forming a secure relationship between the fixed base and the window sash profile. This simplifies the complexity of installation, reduces installation time, lowers installation difficulty, and improves installation efficiency.

[0017] 2. This invention utilizes the above-mentioned novel method for fixing the rotating swing arm and the profile on a drift window track. Compared with the prior art, it is equipped with a fixed base. The outer dimensions of the fixed base are smaller than the opening size of the track profile, which facilitates on-site installation, reduces construction difficulty, and improves work efficiency. At the same time, it also restricts the movement of the fixed base in the opening direction. Moreover, the isosceles trapezoidal groove of the fixed base cooperates with the inner track to restrict the movement of the fixed base in the X-axis direction. The fixed key and the rectangular keyway cooperate to restrict the movement of the fixed base in the Y-axis direction, i.e., the opening direction. The fixed base is fixed in the groove on the side of the window sash profile with self-tapping screws, which restricts the movement of the base in the Z-axis direction.

[0018] 3. The main purpose of this invention is to realize the "disassembled parts transportation and on-site assembly" operation mode of drift window products, so as to significantly reduce operating costs such as production costs, packaging and transportation costs, and on-site installation costs. The overall calculation shows that the cost can be reduced by more than 15%.

[0019] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention. Specific structures can be described with reference to the accompanying drawings of the patent application.

[0025] This invention provides a novel method for fixing a rotating swing arm to a profile on a drift window track. Please refer to [link / reference]. Figures 1 to 5 As shown, the window includes a track window frame 100 and a side window frame 200. A pulley assembly 300 is provided on the track window frame 100. The pulley assembly 300 is connected to a rotating swing arm 400. The rotating swing arm 400 is connected to a fixed base 600 through a fixed shaft 500. The rotating swing arm 400 is also connected to a window sash profile 700 through the fixed base 600.

[0026] It should be noted that the contact height between the rotating arm 400 and the pivot in ordinary sliding windows is limited by structural design and aesthetic considerations, typically around 6-7 millimeters. This results in weak load-bearing capacity of the rotating arm 400, poor durability of hardware components, a repair rate generally exceeding 10%, and significant after-sales service pressure. This invention employs a new structural design and opening method, enabling a contact height between the rotating arm 400 and the pivot greater than 15 millimeters. This provides a load-bearing capacity more than three times that of ordinary sliding windows, allowing for larger window sashes, greater lighting area, and better aesthetics. Furthermore, it avoids durability issues with hardware components, minimizing losses related to after-sales service.

There can be several sets of blind holes 640. In this embodiment, there are also two sets corresponding to the self-tapping screws 800.

[0030] Specifically, the specific structure of the fixed key 900 is shown below. (Combined with...) Figure 1 , Figure 2 as well as Figure 4 As shown, in this embodiment, one end of the fixing key 900 is provided with a hook part, the cross-section of the hook part is in the shape of a hook, the hook part is connected with the buckles 713 provided at both ends of the opening of the opening groove 711 on the side of the window sash profile, the other end of the fixing key 900 is provided with a key body part, the cross-section of the key body part is rectangular, and the key body part is embedded in the rectangular key grooves 610 opened on the left and right sides of the fixing base 600.

[0031] Specifically, the specific structure of the pulley block 300 and the fixed shaft 500 is shown below. (In conjunction with...)
