Description

Technical Field

[0001] This utility model relates to the field of furniture technology, specifically to a folding fan screen with adjustable light transmission area. Background Technology

[0002] Screens, as a traditional type of space-dividing furniture, are widely used in homes, offices, and commercial spaces. Most existing screens are single-function, with their light transmission and visual blocking effects fixed after installation, unable to be flexibly adjusted according to user needs or changes in ambient light. For example, at certain times, users may want the screen to allow some light to maintain a sense of openness; at other times, they may require complete visual privacy. While some screens employ adjustable structures, the adjustment methods are often complex, or the adjusted shapes are not varied enough to meet users' diverse needs for both aesthetics and functionality. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a screen that is not only simple in structure and easy to operate, but also allows for flexible adjustment of the light-transmitting area and visual blocking effect in both the overall layout and the angle of local units.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A folding fan screen with adjustable light transmission area includes a frame. The frame includes a partition strip that divides the frame into several installation units. Each installation unit contains a folding fan unit, which includes a fan surface and a connecting frame. The fan surface is connected to and fixed to the frame via the connecting frame. The connecting frame includes a bracket and a base. A circular connecting sleeve is provided on the base. The bracket is inserted into the circular connecting sleeve and forms a rotatable connection with the base. The fan surface and the frame can be rotated to different usage angles to adjust the light transmission area.

[0006] Furthermore, the bracket includes two connecting rods, one end of which is hinged to each other. The two sides of the folding fan are respectively connected to the two connecting rods. After the connecting rods are rotated in opposite directions and brought together, they are inserted into the circular connecting sleeve.

[0007] Furthermore, the two connecting rods are provided with a pre-tightening angle after being rotated in opposite directions and brought together.

[0008] Furthermore, the bracket also includes two support end plates, which are respectively disposed on both sides of the hinge of the connecting rod.

[0009] Furthermore, the connecting rod has a positioning step at one end that is inserted into the circular connecting sleeve.

[0010] Furthermore, the base and the frame are magnetically connected.

[0011] Furthermore, the magnetic connection specifically involves the base being equipped with a magnet and the frame being an iron frame.

[0012] Compared with the prior art, the beneficial effect of this utility model is that the overall light-transmitting area of ​​the screen can be adjusted by adjusting the usage angle of each screen unit. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides a folding fan screen with adjustable light transmission area, such as... Figure 1 As shown, the screen includes a frame 1, which comprises several dividing strips 11 that divide the frame 1 into several installation units 12. Each installation unit 12 contains a folding fan unit 2. The frame 1 can be square, circular, or any other desired shape, depending on the overall design of the screen. Similarly, the installation units 12 divided by the dividing strips 11 can also be square, circular, or any other desired shape. This embodiment uses a single square installation unit 12 for illustration. Figure 2 As shown.

[0023] The folding fan unit 2 includes a folding fan surface 20 and a connecting frame 21. The folding fan surface 20 is the main component of the screen that blocks light transmission. Figure 4 As shown, the connecting frame 21 includes a support 211 and a base 212. The folding fan surface 20 is connected to the support 211, and the support 211 is connected to the base 212. Specifically, the connection between the support 211 and the base 212 involves a circular connecting sleeve 2120 on the base 212. The support 211 is inserted into the circular connecting sleeve 2120 and can rotate within it, thus achieving a rotatable connection between the support 211 and the base 212. Due to the rotatable connection between the support 211 and the base 212, rotation between them allows for different usage angles 201 to be formed between the folding fan surface 20 and the frame 1, such as... Figure 3 As shown. When the angle of use 201 is 0 degrees, the folding fan surface 20 is flush with the frame 1, and the light-transmitting area is the smallest. When the angle of use 201 is 90 degrees, the folding fan surface 20 is perpendicular to the frame 1, and the light-transmitting area is the largest. Therefore, the overall light-transmitting area of ​​the screen can be adjusted by adjusting the angle of use 201 of each screen unit.

[0024] Preferably, the bracket 211 includes two connecting rods 2111, which are hinged to each other. The two sides of the folding fan surface are respectively connected to the two connecting rods 2111. The two connecting rods 2111 are as follows: Figure 5 Rotate in the direction of the middle arrow, that is, rotate in the opposite direction and merge, such as... Figure 6 As shown. The connecting rods, rotated in opposite directions and joined together, are then inserted into the circular connecting sleeve 2120, forming a rotatable connection with the base 212. The two sides of the folding fan surface are connected to the two connecting rods 2111 respectively. Specifically, they can be glued together, or connecting holes can be provided on both sides of the folding fan surface for the connecting rods 2111 to pass through, or other connection methods commonly used by those skilled in the art.

[0025] Preferably, the two connecting rods 2111 are provided with a pre-tightening angle 2112 after being rotated in opposite directions and brought together, such as... Figure 6As shown. The purpose of setting the pre-tightening angle 2112 is that when the two connecting rods 2111 are inserted into the circular connecting sleeve 2120, the two connecting rods 2111 need to be rotated in opposite directions and then brought together. During the bringing together process, the pre-tightening angle 2112 is eliminated, causing the connecting rods 2111 to undergo elastic deformation in the length direction. After the connecting rods 2111 are inserted into the circular connecting sleeve 2120, due to the elastic restoring force, the connecting rods 2111 tend to move back to the pre-tightening angle 2112 degrees. This can generate friction between the connecting rods 2111 and the wall of the circular connecting sleeve 2120, thereby making the connection between the connecting rods 2111 and the circular connecting sleeve 2120 more secure and reliable.

[0026] Preferably, the bracket 211 further includes two support plates 2113, the support plates 2113 being circular, such as... Figures 4 to 6 As shown, the two support plates 2113 are respectively set on both sides of the hinge of the connecting rod 2111, that is, the two support plates 2113 are located on both sides of the folding fan surface, which support the folding fan surface and can prevent the folding fan surface from tilting.

[0027] Preferably, the connecting rod 2111 has a positioning step 2114 at one end that is inserted into the circular connecting sleeve 2120. The positioning step 2114 is wider than the inner diameter of the circular connecting sleeve 2120. When the connecting rod 2111 is inserted into the circular connecting sleeve 2120, the positioning step 2114 abuts against the circular connecting sleeve 2120, thereby achieving the insertion positioning function.

[0028] Preferably, in some embodiments of this utility model, the connection between the connecting frame 21 and the frame 1 is a magnetic connection. Specifically, a first magnetic element can be provided on the base 212, and a second magnetic element can be provided at the connection position of the frame 1, forming a magnetic connection between the first magnetic element and the second magnetic element.

[0029] Furthermore, the first magnetic component of the base 212 is a magnet, and the frame 1 is an iron frame 1. The first magnetic component and the iron frame 1 form a magnetic connection. At this time, the entire frame 1 is equivalent to the second magnetic component. Therefore, the connecting frame 21 can be attached to any position of the frame 1.

[0030] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0031] It should also be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or may be connected to an intermediary component. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component through an intermediary component.

[0032] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0033] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
