Description

Technical Field

[0001] This invention relates to the field of windows, and particularly to a roller blind mechanism and a roller blind window. Background Technology

[0002] Traditional curtains take up space and are difficult to clean. To address this issue, sunshade roller blinds have been designed inside double-glazed windows. These blinds are raised and lowered by a drive mechanism, providing both light blocking and privacy when needed.

[0003] For example, Chinese invention patent CN201310690729.1 discloses an integrated energy-saving window with a built-in sunshade roller blind, including a window frame, window glass, and a sunshade roller blind device. The device includes a roller, a sunshade roller blind, and a roller blind retraction mechanism. The sunshade roller blind is wound on the roller, and the roller blind retraction mechanism is adapted to drive the roller to retract or extend the sunshade roller blind. However, existing roller blind retraction mechanisms have many parts and complex structures, and the disassembly and assembly process is time-consuming and labor-intensive, which is not conducive to cost reduction.

[0004] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Summary of the Invention

[0005] The purpose of this invention is to provide a roller blind mechanism and roller blind window, which has a simple structure and is easy to assemble and disassemble.

[0006] The objective of this invention is achieved through the following technical solution: a roller blind mechanism, comprising:

[0007] A roller blind assembly, including a roller and a curtain wound around the roller;

[0008] Two end caps are provided, and each end cap is fixedly fitted onto both ends of the reel.

[0009] The mounting bases correspond one-to-one with the end caps;

[0010] A pull cord assembly is connected to the roller drive to drive the curtain fabric to extend and retract;

[0011] The mounting base includes a mounting base body with a recessed portion. A positioning shaft is provided in the recessed portion. The recessed portion is adapted to be fitted over the end cover, and the positioning shaft passes through the end cover to guide the end cover to rotate around the axial direction of the reel.

[0012] Furthermore, the end cap includes:

[0013] The cover is a circular plate structure coaxial with the scroll and covers the end of the scroll;

[0014] The outer ring protrudes from the end face of the cover facing the scroll and is coaxial with the cover.

[0015] The inner ring protrudes from the end face of the cover facing the scroll and is coaxially housed within the outer ring.

[0016] The scroll has a hollow structure, the outer ring is fixedly sleeved on the outside of the scroll, and the inner ring is fixedly inserted inside the scroll.

[0017] Furthermore, the outer contour of the outer ring body is adapted to the inner contour of the recessed portion, and the outer ring body is rotatably embedded in the recessed portion;

[0018] The inner ring body has a positioning hole coaxial with the scroll, and the positioning shaft is adapted to the positioning hole and passes through the positioning hole.

[0019] Furthermore, the roller is formed by splicing a first shaft and a second shaft together, and the upper side of the curtain is clamped and fixed between the first shaft and the second shaft.

[0020] Furthermore, the cross-section of the first shaft is an open ring, and a notch is formed between the two ends of the open ring. The cross-section of the second shaft is a circular ring, and its outer wall is provided with an arc-shaped portion. The second shaft is adapted to be inserted into the first shaft from one end of the first shaft along its axial direction. The outer wall of the second shaft is in close contact with the inner wall of the first shaft. The arc-shaped portion is sealed at the notch and cooperates with the outer wall of the first shaft to form the outer periphery of the roll.

[0021] Furthermore, the opening angle of the notch is less than 180°.

[0022] Furthermore, the pull cord assembly includes:

[0023] A magnetic control box equipped with rollers;

[0024] A pull rope is wound around the reel, with one end connected to the reel and the other end passing over the roller and connected to the mounting base;

[0025] The curtain fabric is provided with a counterweight on its lower side. The counterweight is adapted to drive the curtain fabric to roll downwards under the action of gravity. The pull cord is adapted to roll up under the action of the roller and drive the magnetic control box to move upwards. When the magnetic control box moves downwards, the pull cord unrolls and drives the roller to rotate, so as to roll up the curtain fabric upwards.

[0026] Furthermore, the spool has a limiting hole in the radial direction, which is located directly above the mounting base. The mounting base has a guide hole and a connecting hole in the vertical direction. One end of the pull rope is confined inside the spool, and the other end passes through the limiting hole, is wound around the spool, and then passes through the guide hole and the roller in sequence before passing through the connecting hole and being tied to the mounting base.

[0027] Furthermore, it also includes a framework, the framework comprising:

[0028] The upper crossbeam connects the tops of the two mounting bases;

[0029] The lower crossbeam is connected between the bottoms of the two mounting bases;

[0030] There are two side beams, each connected to the bottom of a different mounting base;

[0031] The roller is located between the upper crossbeam and the lower crossbeam, and the curtain is located between the two side beams.

[0032] In addition, the present invention also provides a roller blind window, including the roller blind mechanism described above.

[0033] Compared with the prior art, the present invention has the following beneficial effects: The present invention fixes end caps at both ends of the reel and forms a recess and a positioning shaft on the mounting base. The recess is suitable for being fitted outside the end cap, and the positioning shaft passes through the end cap to guide the end cap to rotate around the axial direction of the reel. This can drive the reel to rotate reliably while having a simple structure, few parts, and convenient disassembly and assembly, which helps to reduce production costs. Attached Figure Description

[0041] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not the entire structure. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0042] The terms “comprising” and “having”, and any variations thereof, used in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0043] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0044] Please see Figures 1 to 3As shown, a roller blind mechanism corresponding to a preferred embodiment of the present invention includes: a roller blind assembly 100, including a roller 110 and a curtain 120 wound around the roller 110; two end caps 200, respectively fixedly sleeved on both ends of the roller 110; mounting seats 300, corresponding one-to-one with the end caps 200; and a pull cord assembly 400, which is tractively connected to the roller 110 to drive the curtain 120 to retract and extend; wherein, the mounting seat 300 includes a mounting seat body 310, the mounting seat body 310 having a recessed portion 320, a positioning shaft 330 disposed within the recessed portion 320, the recessed portion 320 being adapted to be sleeved on the end caps 200, and the positioning shaft 330 passing through the end caps 200 to guide the end caps 200 to rotate axially around the roller 110.

[0045] The present invention provides an end cap 200 fixedly installed at both ends of the reel 110, and a recess 320 and a positioning shaft 330 formed on the mounting base 300. The recess 320 is adapted to be sleeved on the end cap 200, and the positioning shaft 330 passes through the end cap 200 to guide the end cap 200 to rotate around the axial direction of the reel 110. This invention can reliably drive the reel 110 to rotate, while having a simple structure, few parts, and convenient assembly and disassembly, which helps to reduce production costs.

[0046] Furthermore, referring to Figure 4 and Figure 5 As shown, the roller 110 has a hollow structure with open ends. The roller 110 is formed by splicing together a first shaft 111 and a second shaft 112, with the upper side of the curtain 120 clamped and fixed between the first shaft 111 and the second shaft 112. Compared to conventional adhesive bonding or additional connectors to fix the curtain 120 to the roller 110, the above structure makes it easier to assemble and disassemble the curtain 120 without the need for additional tools.

[0047] Specifically, the first shaft 111 has an open ring cross-section, with a notch 1111 formed between its two ends. The second shaft 112 has a circular ring cross-section, and an arc-shaped portion 1121 protrudes from its outer wall, extending axially to both ends of the second shaft 112. The second shaft 112 is adapted to be inserted into the first shaft 111 from one side along its axial direction. The outer wall of the second shaft 112 is in close contact with the inner wall of the first shaft 111, and the arc-shaped portion 1121 seals the notch 1111. When the first shaft 111 and the second shaft 112 are inserted into place, their ends are flush. The outer wall of the arc-shaped portion 1121 and the outer wall of the first shaft 111 cooperate to form the outer periphery of the roll 110. The upper side of the curtain 120 is sandwiched between the inner wall of the first shaft 111 and the inner wall of the second shaft 112, and the lower side extends to the outside through the gap between the notch 1111 and the arc-shaped part 1121.

[0048] Preferably, the opening angle of the notch 1111 is less than 180°, so as to prevent the first shaft 111 and the second shaft 112 from being separated radially, thereby improving the reliability of the two after splicing.

[0049] Furthermore, referring to Figure 2 and Figure 3 As shown, the end cap 200 includes a cap body 210, an outer ring body 220, and an inner ring body 230. The cap body 210 is a circular plate-like structure coaxial with the spool 110 and covers the end of the spool 110. The outer ring body 220 protrudes from the end face of the cap body 210 facing the spool 110 and is coaxial with the cap body 210. The inner ring body 230 protrudes from the end face of the cap body 210 facing the spool 110 and is coaxially housed within the outer ring body 220. The outer ring body 220 is fixedly sleeved on the outside of the spool 110, and the inner ring body 230 is fixedly ringed within the inner hole of the spool 110. Specifically, the end cap 200 can be press-fitted with the spool 110.

[0050] By adopting the above structure, on the one hand, the end cap 200 and the scroll 110 can be reliably fixed, and on the other hand, the first shaft 111 and the second shaft 112 can be limited to ensure that the two are reliably connected together.

[0051] Furthermore, the outer contour of the outer ring 220 is adapted to the inner contour of the recess 320, and the outer ring 220 is rotatably fitted into the recess 320 to realize the rotation of the end cap 200 relative to the mounting base 300. The inner ring 230 has a positioning hole 240 coaxial with the roller 110, and the positioning shaft 330 is adapted to the positioning hole 240 and passes through the positioning hole 240.

[0052] Furthermore, referring to Figures 1 to 3 As shown, the pull cord assembly 400 includes a magnetic control box 410 and a pull cord 420. The magnetic control box 410 is equipped with a roller (not shown). There is a gap between the curtain fabric 120 and the end cap 200 for the pull cord 420 to be wound. The pull cord 420 is wound around a roller 110, with one end connected to the roller 110 and the other end passing over the roller and connected to the mounting base 300. A counterweight 130 is provided on the lower side of the curtain fabric 120. In its natural state, the counterweight 130 is adapted to drive the curtain fabric 120 downward under the action of gravity, and the pull cord 420 is adapted to be wound up under the action of the roller 110, and drive the magnetic control box 410 to move upward. When the magnetic control box 410 moves downward, the pull cord 420 unwinds and drives the roller 110 to rotate, so as to wind up the curtain fabric 120 upward.

[0053] In this embodiment, the spool 110 has a limiting hole 113 formed radially, which extends through the inside and outside of the spool 110 and is located directly above the mounting base 300. Preferably, the limiting hole 113 is formed in the second shaft 112. One end of the pull rope 420 is confined inside the spool 110. For example, a knot can be tied at this end of the pull rope 420, which is received inside the spool 110 through the end of the spool 110 and cannot pass through the limiting hole 113. The mounting base body 310 of the mounting base 300 has a guide hole 340 and a connecting hole 350 formed vertically. The other end of the pull rope 420 passes through the limiting hole 113, is wound around the spool 110, and then passes through the guide hole 340 and the roller in sequence before passing through the connecting hole 350 and being tied to the mounting base 300.

[0054] Furthermore, the roller blind mechanism also includes a frame 500, which comprises an upper crossbeam 510, a lower crossbeam 520, and two side beams 530. The upper crossbeam 510 connects the tops of the two mounting seats 300, the lower crossbeam 520 connects the bottoms of the two mounting seats 300, and there are two side beams 530, each connected to the bottom of a different mounting seat 300. The roller 110 is located between the upper crossbeam 510 and the lower crossbeam 520, and the curtain fabric 120 is located between the two side beams 530.

[0055] Specifically, a first insertion portion 360 is formed on the top of the mounting base body 310 extending axially along the spool 110. The first insertion portions 360 of the two mounting bases 300 are arranged opposite to each other, and the end of the upper crossbeam 510 is adapted to engage with the first insertion portion 360. A second insertion portion 370 is formed on the bottom of the mounting base body 310 extending axially along the spool 110. The second insertion portions 370 of the two mounting bases 300 are arranged opposite to each other, and the end of the lower crossbeam 520 is adapted to engage with the second insertion portion 370. Furthermore, a third insertion portion 380 is formed on the top of the mounting base body 310 extending downward in the vertical direction, and the top of the side beam 530 engages with the third insertion portion 380. One side beam 530 is recessed inward to form a groove 531. The groove 531 extends vertically to its top. The magnetic control box 410 is slidably installed in the groove 531. The upper opening of the groove 531 is connected to the guide hole 340 and the connecting hole 350 to facilitate the routing of the pull rope 420.

[0056] Furthermore, the present invention also provides a roller blind window, including the aforementioned roller blind mechanism. The roller blind window further includes a window frame and window glass fixed to the window frame. The roller blind mechanism is installed in the window frame and housed within the window glass. The roller blind window also includes a magnetic handle disposed outside the window frame. The magnetic handle magnetically engages with the magnetic control box 410. When the magnetic handle moves downward, it can drive the magnetic control box 410 downward to roll up the curtain 120. When the magnetic handle moves upward, it can drive the magnetic control box 410 upward to unroll the curtain 120.

[0057] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
