[0036] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other in the absence of conflict. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0037] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0038] The embodiment of the present application provides a technical solution for the structure of a hidden Venetian blind. The gear of the adjustment mechanism meshes with the linkage rack in the frame, and the gear meshing with the linkage rack in the frame drives the entire linkage rack to move up and down, while driving the rotation of other gears until the entire row of blades rotates together, thereby achieving the purpose of opening and closing the entire Venetian blind. See below for details.

[0039] Hereinafter, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. It should be noted that these exemplary embodiments can be implemented in many different forms and should not be construed as being limited to the embodiments described herein.

[0040] like Figures 1 to 9 As shown, the hidden shutter structure may include: a frame 1, an adjustment mechanism 2; and in some embodiments, a fastener 3 may also be included.

[0041] The frame 1 has a first side and a third side opposite to each other, and a second side and a fourth side opposite to each other. The first side, the second side, the third side and the fourth side are enclosed to form a C-shaped groove body, in which a linkage rack 11 is arranged; a plug hole 12 is arranged on the second side, and a strip-shaped opening 13 of the C-shaped groove body is arranged on the fourth side. The frame 1 is used to accommodate the linkage rack 11 and the adjustment mechanism 2, and the surface of the linkage rack 11 has a tooth pattern that matches the gear 22. The C-shaped groove body allows: if there is a problem when producing the groove body or assembling the adjustment mechanism 2, the internal situation can be directly seen, and maintenance and modification are easy.

[0042] The adjustment mechanism 2 is fixed on the frame 1. The adjustment mechanism 2 includes an arc-shaped connection part 21, a gear 22 and a limit part 23. The arc-shaped connection part 21 is located on the outer side of the fourth side. One end of the limit part 23 is connected to the arc-shaped connection part 21, and the other end passes through the strip opening 13 and extends out of the plug hole 12. The gear 22 is rotatably sleeved on the limit part 23. The arc-shaped connection part 21 is used to connect with the blades. The blades matched with the arc-shaped connection part 21 do not need special machines for processing. The processing process of the blades is simpler and more convenient. The same blades can be made of wood materials or hard polyvinyl chloride materials.

[0043] The interlocking rack 11 is meshed with the gear 22. By rotating one gear 22, the interlocking rack 11 can be driven to move, and the interlocking rack 11 can drive the rotation of other gears, so that all blades can rotate synchronously.

[0044] In this embodiment, the adjustment mechanism 2 is fixed on the frame 1, connected to the blades through the arc-shaped connecting portion 21, and the gear 22 and the linkage rack 11 act on each other, driving the entire linkage rack 11 to translate up and down, while driving the rotation of other gears until the entire row of blades rotates together, thereby achieving the purpose of opening and closing the entire blinds. The C-shaped trough has an open structural design, which makes it difficult for debris to hide, and the inner hole debris and sundries are easy to clean. The limit portion 23 passes through the strip opening 13 and the arc-shaped connecting portion 23, so that the adjustment mechanism 2 can slide smoothly during the adjustment process, and will not be stuck due to the accumulation of debris, thereby achieving smooth operation of the adjustment mechanism 2.

[0045] In an optional embodiment, the limiting portion 23 includes a conical block 231 and a fixing column 232 .

[0046] The conical block 231 is located at one end of the fixing column 232 away from the arc-shaped connecting portion 21. The fixing column 232 passes through the insertion hole 12, and the conical block 231 is located outside the second side of the frame 1.

[0047] The conical block 231 includes a first conical block and a second conical block which are spaced apart, and the first conical block 231 and the second conical block 231 form a hook. The first conical block 231 and the second conical block 231 can be relatively close to each other under external pressure, and can be spaced apart without external pressure. Under external pressure, the space between the first conical block and the second conical block is reduced, so that the conical block 231 can pass through the insertion hole 12. When there is no external pressure, the space between the first conical block and the second conical block allows the conical block to clamp the frame.

[0048] In this embodiment, the design of the conical block 231 allows it to be squeezed close under the action of external force, so that the limit portion 23 can be inserted into the frame through the strip opening 13 and the insertion hole 12. When there is no external force, the conical block 231 maintains the interval to prevent the limit portion 23 from accidentally falling out, thereby achieving stable fixation. This design makes the installation and removal of the adjustment mechanism 2 more convenient.

[0049] In an optional embodiment, the hidden shutter structure further includes a fastener 3. The shape of the fastener 3 can be cylindrical, or other shapes according to actual conditions. The fastener 3 can be made of plastic material, or other materials can be used according to requirements. There is a mounting hole in the middle of the fastener 3, and the fixing column 232 passes through the mounting hole.

[0050] The fastener 3 is sleeved on the fixing column 232 and abuts between the conical block 231 and the frame 1. This can further stabilize and fix the adjustment mechanism 2.

[0051] In an optional embodiment, the linkage rack 11 is respectively located on the inner side of the first side and the third side and is symmetrically arranged. The linkage rack 11 can be made of metal material and has a long strip shape. The symmetrically arranged linkage rack 11 can evenly distribute the force inside the frame and can better mesh with the gear 22 to achieve synchronous adjustment.

[0052] In an optional embodiment, a groove 111 is provided at one end of the linkage rack 11, and a protrusion 112 is provided at the other end. The groove may be a T-shaped groove, and the protrusion may be a T-shaped protrusion. The groove and the protrusion may also be selected in different and mutually matching shapes according to actual conditions. Among them, the groove 111 is adapted to the protrusion 112. The groove 111 and the protrusion 112 are used to connect different linkage racks 11. The linkage rack 11 may also be connected to multiple linkage racks by other means such as threaded connection, clamping connection and welding.

[0053] In this embodiment, by riveting the grooves 111 and the protrusions 112 , the assembly of multiple linked racks 11 can be achieved, so that the length of the racks 11 can be adjusted and customized according to actual needs, thereby improving the flexibility of the design.

[0054] In an optional embodiment, the diameter of the gear 22 is greater than the width of the strip-shaped opening 13. Such a design can prevent the gear 22 from slipping out through the strip-shaped opening 13 during operation, thereby achieving overall stability and safety of the adjustment mechanism 2.

[0055] In an optional embodiment, there are multiple jacks 12, and the multiple jacks 12 are distributed along the length direction of the frame 1. The shape of the jack 12 can be circular or other shapes, and its size and spacing can be determined according to design requirements and the size of the adjustment mechanism 2. Correspondingly, there are multiple adjustment mechanisms 2, and one adjustment mechanism 2 corresponds to one jack 12. The provision of multiple jacks 12 and adjustment mechanisms 2 can fix the adjustment mechanism at different positions of the frame 1, and at the same time can better match the number of required adjustment mechanisms 2 according to actual needs.

[0056] In an optional embodiment, the frame 1 is made of aluminum or aluminum alloy. The frame 1 can also be made of other materials according to actual conditions. Aluminum and aluminum alloy have lower density and higher strength and hardness, which can make the frame relatively light and improve the durability of the frame.
