Description

Technical Field

[0001] This utility model relates to a skylight structure, specifically a sleeve axle pulley cable skeleton structure. Background Technology

[0002] With the development of sunshade technology, there is a growing demand for sunshades that can be started and stopped at any position. The applicant's earlier patent application for a sunshade with patent number 2023206560001 uses a guide wheel to unwind the rope. The limited installation space on the side frame increases the difficulty of producing the side frame or guide rail. Summary of the Invention

[0003] This invention provides a sleeve-shaft pulley cable skeleton structure that can stably discharge the drive cable of the sunshade curtain, while also taking into account the connection with the frame, and is easy to produce and install.

[0004] The technical solution adopted by this utility model is: a sleeve shaft pulley cable skeleton structure, characterized in that: it includes a skeleton body, the skeleton body is provided with two or more plug parts facing forward, the two or more plug parts are respectively inserted into the cavity or guide groove of the side guide rail, a guide groove is provided on the outer side of the skeleton body, a sleeve shaft passes through the two side walls of the guide groove, the sleeve shaft passes through the pulley in the guide groove, and the curtain guide opening is started on the inner side of the skeleton body.

[0005] The plug is inserted into the upper cavity or guide groove of the guide rail, and the plug is locked in place by screws through the upper wall of the cavity or guide groove of the guide rail.

[0006] The plug is inserted into the lower cavity or guide groove of the guide rail, and the plug is locked in place by screws passing through the lower wall of the cavity or guide groove of the guide rail.

[0007] The upper opening of the curtain guide is provided with an upper pressure head that guides and presses the upper side of the curtain.

[0008] The lower opening of the curtain guide is provided with a support head that is lower than the upper pressure head and guides and supports the curtain.

[0009] The support head is provided with a pressing head that connects the inner side of the spring sheet to the side of the pressing curtain.

[0010] The sleeve shaft is threaded to lock either side wall of the guide groove.

[0011] The inner wall of the pulley connecting sleeve shaft has a lubricating oil groove.

[0012] This utility model adopts an independent frame structure for installing and connecting the side frame guide rails. The double-plug joint is secured with screws, improving connection strength. Furthermore, the side frame eliminates the need for cable guide wheels and other structures, simplifying production and assembly. A threaded connection on the sleeve shaft facilitates easy assembly. A pulley connected to the sleeve shaft, combined with a lubrication groove, improves the stability of the cable support on the pulley, reduces cable running resistance, increases service life, and reduces friction noise. A curtain guide opening is added to the inner side of the frame body, corresponding to the side frame guide rails and the rear frame sunshade curtain roller for guiding the curtain roll. An upper pressure head presses against the outer curtain, a support head supports the curtain, and a lower pressure head presses against the inner side of the curtain's side spring, ensuring stable and smooth curtain guidance and facilitating smooth curtain roll-up.

[0017] The following is a further written explanation in conjunction with the accompanying drawings.

[0018] Figure 1 , 2 As shown in Figure 3: A sleeve-shaft pulley cable skeleton structure, the skeleton body 1 is provided with upper and lower plug parts 2 and 3 facing forward. The upper and lower plug parts 2 and 3 are respectively inserted into the upper guide groove 13 and lower cavity 14 of the side guide rail 12 and are respectively locked by screws 4. A guide groove 5 is provided on the outer side of the skeleton body 1. A sleeve shaft 6 is passed through the two side walls of the guide groove 5. The sleeve shaft 6 passes through the pulley 7 in the guide groove 5. A curtain guide opening 8 is provided on the inner side of the skeleton body. An upper pressure head 9 is provided at the upper opening of the curtain guide opening to guide and press the upper part of the curtain side. A support head 10 is provided at the lower opening of the curtain guide opening, which is lower than the upper pressure head and guides and supports the curtain. A lower pressure head 11 is provided at the inner side of the spring connecting the curtain side.

[0019] In this embodiment, the sleeve shaft has a built-in threaded locking guide groove on either side wall.

[0020] Based on this embodiment, a lubricating oil groove can be opened in the inner wall of the pulley connecting sleeve shaft to improve the pulley's cable discharge performance.
