Description

Technical Field

[0001] This invention relates to the field of screen technology, and in particular to a quick-assembly and disassembly screen. Background Technology

[0002] A screen is a traditional piece of furniture and a common interior decoration, primarily serving to divide, screen, beautify, and harmonize spaces. In open spaces, screens can flexibly divide different functional areas and can also screen off parts of the space. They are widely used in restaurants, hotels, offices, and other places to create relatively private environments.

[0003] In various exhibitions, screens often serve to distinguish different exhibition areas. Since different exhibition areas may exhibit different content each day, the number and size of the exhibits, as well as the area of ​​the exhibition space, vary, requiring frequent adjustments to the size and angle of the screens. However, existing folding screens connect each panel with hinges. When adding panels, screws are used to install new panels, making the overall installation complex and time-consuming. Moreover, with long-term folding use, the hinges can easily loosen, causing gaps between parts and reducing the stability between the different panels of the screen. Summary of the Invention

[0004] In order to overcome the shortcomings mentioned in the background art, this application provides a quick-assembly and disassembly screen.

[0005] A quick-assembly screen includes multiple frames, which are rotatably connected by quick-connect components. Each frame includes a first support portion and a second support portion. A pivot is rotatably connected to the second support portion. The quick-connect component includes a mating portion and a magnetic attraction mechanism for magnetically engaging with the mating portion. The mating portion is mounted on each pivot, and the magnetic attraction mechanism is mounted on the corresponding first support portion.

[0006] As one embodiment, the top and bottom of the frame are provided with fixing mechanisms for fixed connection with the building.

[0007] As one embodiment, the magnetic attraction mechanism includes a housing for contacting and magnetically engaging with the corresponding docking portion. The housing is provided with a dividing member and a permanent magnet. The dividing member divides the housing into two symmetrical magnetically conductive shells. The dividing member is made of a non-magnetically conductive material. The permanent magnet is rotatably connected to the housing.

[0008] As one embodiment, a dial is installed at one end of the permanent magnet located outside the housing, and the dial is provided with a groove for facilitating its rotation.

[0009] As one embodiment, a limiting rod is fixedly connected to one side of the dial, the axis of the limiting rod coincides with the axis of the dial, and a limiting groove is provided on the second support to limit the rotation angle corresponding to the limiting rod.

[0010] In one embodiment, the docking part is provided with a mating interface and a ferromagnetic metal block for magnetically engaging with the housing. The mating interface of the docking part is provided with an inclined surface for guiding the housing, and the ferromagnetic metal block is located inside the corresponding mating interface.

[0011] As one embodiment, the second support is equipped with a ferromagnetic metal sheet for maintaining stability between the frames when they are stacked, and the ferromagnetic metal sheet is magnetically attracted to the magnetic attraction mechanism.

[0012] In one embodiment, the second support is provided with a locking assembly for restricting the rotation of the shaft. The locking assembly includes a pressing part for applying a pressing force to the shaft. The pressing part is slidably connected to the corresponding second support. A rotating member is rotatably mounted on the second support, and a lever is mounted on the rotating member for pushing the corresponding pressing part toward the shaft.

[0013] As one embodiment, the second support portion is provided with a spring for resetting the compression portion.

[0014] As one embodiment, a mounting sleeve corresponding to the extrusion part is installed on the rotating shaft. The extrusion end of the extrusion part is a flexible structure, and both the extrusion end of the extrusion part and the corresponding mounting sleeve are provided with friction patterns to increase friction.

[0015] The beneficial effects of this application are: This invention uses quick-connect components to rotatably connect frames. A mating part is installed on each rotating shaft, and a magnetic attraction mechanism is installed on the first support part. The magnetic attraction mechanism magnetically attracts adjacent frames together, enabling quick connection and facilitating disassembly. Depending on the size or usage requirements, different numbers of frames can be connected using magnets. Compared to pin-type quick-connect methods, the magnetic attraction mechanism directly adsorbs and adheres to the mating part, eliminating gaps at the connection point and reducing the risk of loosening and instability in the screen due to gaps. This ensures a stable connection between the frames.

[0016] Other technical solutions of the present invention can also achieve the following technical effects: By setting a docking part and a shell, and setting a dividing part and a permanent magnet on the shell, the dividing part is made of non-magnetic material. The dividing part divides the shell into two symmetrical magnetic shells. The permanent magnet is rotatably connected to the shell, so that the magnetization or demagnetization state of the shell can be switched when the permanent magnet is rotated. When the frames need to be connected, they can be tightly attracted together by magnetic force. When the frames need to be separated, they can be easily separated, which improves the efficiency of installation and separation.

[0017] The docking section is equipped with an interface and a ferromagnetic metal block. An inclined surface is provided at the interface to guide the shell and prevent it from shifting. This ensures that the shell and the corresponding ferromagnetic metal block are aligned and their contact surfaces are fully fitted, thus guaranteeing the magnetic attraction effect.

[0018] By setting up a pressing part, the pressing part and the corresponding rotating shaft are pressed against each other, thereby increasing the friction between the two and increasing the resistance encountered when the rotating shaft rotates. This ultimately locks the two frames together, maintaining a stable angle between the frames and ensuring the overall stability of the screen. Attached Figure Description

[0021] To make the above-mentioned objectives, features, and advantages of the present invention more apparent and understandable, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] A quick-assembly and disassembly screen, such as Figures 1-4 As shown, the system includes multiple frames 1, each with a fan-shaped section in the center. The frames 1 are connected sequentially, and are rotatably connected via quick-connect components 2, allowing the angles between them to change. Each frame 1 includes a first support 101 and a second support 102. The axes of the first and second support 101 coincide and both face vertically. A rotating shaft 103 is rotatably connected to the second support 102, located between the corresponding second support 102 and the adjacent first support 101. The quick-connect component 2 includes a docking part 201 and a magnetic attraction mechanism. The magnetic attraction mechanism is used to magnetically engage with the corresponding docking part 201. Two docking parts 201 are mounted on each rotating shaft 103, and the magnetic attraction mechanism is mounted on the corresponding first support 102. On the support 101, two magnetic attraction mechanisms are provided on the first support 101. The magnetic attraction mechanisms are on the same horizontal plane as the corresponding docking parts 201. The magnetic attraction mechanisms can use magnets to magnetically attract two adjacent frames 1 together, so that the frames 1 can be quickly connected. It is also convenient to disassemble the two frames 1. Depending on the size of different usage scenarios or usage needs, different numbers of frames 1 can be connected together by magnets. In addition, compared with the quick-connect method of the pin, the connection of frames 1 by magnets directly attracts and adheres to the docking parts 201, so that there is no gap between the two. This directly eliminates the gap of the parts at the connection position, reduces the loosening of the connection due to the gap, and reduces the instability of the screen caused by the gap. It ensures that the connection between the frames 1 always maintains a stable connection.

[0023] In one embodiment, the top and bottom of frame 1 are provided with fixing mechanisms for connecting to the building wall. The fixing mechanism can be a bolt or an adhesive part that can be bonded to the wall. The bolt or adhesive part can face the vertical wall or the upper and lower floor slabs. When the bolt or adhesive part faces the vertical wall, the screen can be installed on the vertical wall by the bolt or adhesive part. During installation, the screen is first unfolded into a straight line, and then fixed to the vertical wall by the bolt or adhesive part on frame 1. When the bolt or adhesive part faces the upper and lower floor slabs, the screen can be adjusted to different angles. By rotating frame 1, an angle is formed between frames 1. The screen can be adjusted to different shapes by rotating frame 1, such as making the screen as a whole arc or wave shape. Then, it is fixed to the upper and lower floor slabs by bolt or adhesive part. This is suitable for different building and usage needs and has a wider range of applications.

[0024] Furthermore, when installing screens on vertical walls, the installation space and unfolded length are limited by the surrounding environment. On walls with limited space, some excessively long screens with numerous panels cannot be fully unfolded, resulting in insufficient display of their designs. This is particularly problematic in exhibitions where different content may be displayed in different areas daily, necessitating frequent installation of screens with different designs and styles on different walls. When the overall length of the screen is unsuitable, installation or removal of panels is impractical, inefficient, and time-consuming. To address this issue, the frames 1 of this invention can be quickly assembled and disassembled using a magnetic mechanism. By rapidly changing the number of frames 1 on the screen, it can be adapted to different wall sizes, meeting the needs of installing on different walls in different exhibitions, thus broadening its applicability.

[0025] In one embodiment, such as Figures 3-6As shown, the magnetic attraction mechanism includes a docking part 201 and a housing 202. The housing 202 is used to contact and magnetically engage with the corresponding docking part 201. The docking part 201 is made of ferromagnetic material. The housing 202 is embedded in the second support part 102 on the side facing the adjacent rotating shaft 103. A dividing piece 203 and a permanent magnet 204 are provided on the housing 202. The dividing piece 203 is made of non-magnetic material and is a copper sheet. The copper sheet divides the housing 202 into two symmetrical magnetically conductive shells. The housing 202 is made of silicon steel. The two silicon steel shells sandwich the copper sheet in the middle. The permanent magnet 204 and... The housing 202 is rotatably connected. The permanent magnet 204 can be a neodymium iron boron magnet. The permanent magnet 204 is cylindrical in shape and is divided into two semi-cylinders along its axis. The two semi-cylinders correspond to the N pole and S pole of the permanent magnet 204, respectively. Most of the permanent magnet 204 is located inside the housing 202, with only a small portion at its end outside the housing 202. By rotating the permanent magnet 204, the housing 202 can be magnetized or demagnetized. When all the frames 1 are not connected and the housing 202 is in a demagnetized state, Figure 6Taking the direction shown as an example, the two poles of the permanent magnet 204 are distributed vertically. The magnetic field lines emitted by the N pole of the permanent magnet 204 can return to the S pole. However, since the shell 202 is made of silicon steel, which has excellent magnetic permeability, all the magnetic field lines emitted by the permanent magnet 204 are located inside the shell 202. The shell 202 does not leak magnetism and therefore does not possess magnetism. The two frames 1 cannot be connected together by magnetic attraction. When it is necessary to connect the two frames 1, the permanent magnet 204 can be rotated 90° first, and then the shell 202 can be aligned with the corresponding mating part 201. Alternatively, the shell 202 can be aligned with the mating part 201 first, and then the permanent magnet 204 can be rotated 90°. Both operation sequences are acceptable. When the permanent magnet 204 is rotated 90°, its N and S poles are positioned to the left and right. The magnetic field lines emitted by the N pole of the permanent magnet 204 first spread along the inside of the shell 202. The magnetic field lines tend to move towards the S pole. However, because the non-magnetic copper sheet directly isolates the two silicon steel shells and the magnetic field lines, the magnetic field lines cannot flow directly from the N pole to the S pole inside the shell 202. Therefore, the magnetic field lines can only flow out from one side of the silicon steel shell and begin to travel in the air. The magnetic field lines bypass the copper sheet in the air and flow into the other side of the silicon steel shell. Finally, the magnetic field lines reach the S pole through the silicon steel shell. Because the magnetic field lines are exposed to the air during this process, the shell 202 experiences "magnetic leakage," which allows the ferromagnetic mating part 201 to receive the magnetic field lines. This causes a magnetic force to attract the two parts. When the mating part 201 contacts the shell 202, the two parts can be firmly attracted together, thus achieving a magnetic connection between the two frames 1. When it is necessary to disconnect the connection between the two frames 1, simply reverse the permanent magnet 204 by 90° to demagnetize the housing 202. At this time, there is no magnetic force between the housing 202 and the docking part 201, and the two frames 1 can be easily separated, thereby improving efficiency.

[0026] In one embodiment, such as Figure 4 and Figure 5 As shown, a dial 205 is installed at one end of the permanent magnet 204 located outside the housing 202. The axis of the dial 205 coincides with the axis of the corresponding permanent magnet 204. The dial 205 is provided with a groove to facilitate its rotation. The dial 205 exposes part of its position outside the second support 102 through the mounting groove, so that people can rotate the corresponding permanent magnet 204 by turning the dial 205, thereby selecting the magnetization and demagnetization state of the corresponding magnetic attraction mechanism. This facilitates quick assembly and disassembly of the frames 1 and improves the efficiency of screen installation and disassembly.

[0027] In one embodiment, such as Figures 5-7As shown, a limiting rod 206 is fixedly connected to the side of the dial 205 away from the adjacent permanent magnet 204. The limiting rod 206 is located inside the adjacent second support part 102. The axis of the limiting rod 206 coincides with the axis of the dial 205. A limiting groove is provided inside the second support part 102. The limiting rod 206 is located inside the corresponding limiting groove. The limiting groove limits the maximum rotation angle of the corresponding limiting rod 206 to 90°, so that the permanent magnet 204 can rotate 90° each time. This avoids the user's lack of experience causing the rotation angle to be too large, which would prevent the magnetization and demagnetization states of the magnetic attraction mechanism from being switched effectively.

[0028] In one embodiment, such as Figure 3 As shown, the docking part 201 is provided with a mating interface and a ferromagnetic metal block 2011. The mating interface is an expansion-type opening. The end of the expansion-type opening facing the corresponding housing 202 is the large end, and the end away from the corresponding housing 202 is the small end. The ferromagnetic metal block 2011 is located inside the corresponding mating interface. The ferromagnetic metal block 2011 is provided at the small end of the mating interface. The ferromagnetic metal block 2011 is used to magnetically engage with the corresponding housing 202. The mating interface of the docking part 201 is provided with a bevel for guiding the housing 202. By guiding the housing 202 with the bevel, the housing 202 can be directly aligned with the corresponding ferromagnetic metal block 2011, and the contact surfaces of the two can be fully fitted to ensure the adsorption effect. When the ferromagnetic metal block 2011 and the housing 202 are in contact with each other, the lengths of their contact surfaces in the horizontal direction are equal, so that the ferromagnetic metal block 2011 and the housing 202 will not be misaligned or offset in the horizontal direction.

[0029] In one embodiment, such as Figure 2 and Figure 3As shown, a ferromagnetic metal sheet 1021 is installed on the second support 102 to keep the frames 1 stable when stacked. The ferromagnetic metal sheet 1021 is magnetically attracted to the magnetic attraction mechanism. When the screen needs to be stored, all the frames 1 can be separated first, and then all the magnetic attraction mechanisms can be switched to the magnetized state. Then, the two frames 1 are brought closer together, so that the first support 101 and the second support 102 of one frame 1 are aligned with the second support 102 and the first support 101 of the other frame 1, respectively. Both the first support 101 and the second support 102 are provided with clearance openings to prevent interference between parts. For example, the dial 205 extending from the second support 102 enters the clearance opening of the first support 101, so that the first support 101 and the second support 102 of the two frames 1 can fit together tightly. To avoid interference with the dial 205, when the entire surface of the first support part 101 of a frame 1 is attached to the second support part 102, although the magnetic attraction mechanism is not attached to the ferromagnetic metal sheet 1021, there is still magnetic attraction between the two, which makes the frames 1 stable when stacked together. Moreover, in order to avoid excessive magnetic attraction when the two frames 1 are stacked together, the ferromagnetic metal sheet 1021 is placed in the groove of the second support part 102, thereby increasing the distance between the ferromagnetic metal sheet 1021 and the corresponding magnetic attraction mechanism, thereby reducing the magnetic force. This means that when the stacked frames 1 are separated, it is not necessary to switch the magnetic attraction mechanism to the demagnetizing state first, thereby improving the separation efficiency. This situation is suitable for storing the screen in an interference-free environment, where there is almost no external interference, and it is not necessary to keep the frames 1 in a very tight connection state, but to keep them stacked.

[0030] In one embodiment, such as Figures 1-3 , Figure 8 and Figure 9As shown, a locking assembly 3 for restricting the rotation of the rotating shaft 103 is provided on the second support 102. Two locking assemblies 3 can be symmetrically arranged on each second support 102. The locking assembly 3 includes a pressing part 301 for applying pressure to the rotating shaft 103. By pressing the pressing part 301 against the corresponding rotating shaft 103, the friction between the two is increased, thereby increasing the resistance encountered by the rotating shaft 103 when it rotates, thus achieving locking between the two frames 1 and maintaining a stable angle between the frames 1. The pressing part 301 is slidably connected to the corresponding second support 102. The pressing part 301 is located on the side of the first support 101 facing the corresponding rotating shaft 103. A rotating component 302 is rotatably mounted on the upper part. The axis of the rotating component 302 extends perpendicularly to the movement direction of the extrusion part 301. A lever 303 is mounted on the rotating component 302. A knob is provided at one end of the rotating component 302 located outside the second support part 102. A clearance opening corresponding to the knob is also provided on the first support part 101. By rotating the knob, the rotating component 302 drives the corresponding lever 303 to rotate 90°. The lever 303 presses against the adjacent extrusion part 301, causing the extrusion part 301 to apply extrusion force to the corresponding rotating shaft 103, thereby increasing the rotational resistance of the rotating shaft 103. After the lever 303 rotates 90°, the contact surface between the lever 303 and the corresponding extrusion part 301 is on the same vertical plane.

[0031] In one embodiment, such as Figure 8 and Figure 9 As shown, a spring is provided on the second support part 102 to reset the pressing part 301. When it is necessary to release the locking state between the frames 1, the reverse lever 303 is reversed to reset it. At this time, the pressing part 301 is reset under the action of the spring force. The pressing part 301 is disengaged from the rotating shaft 103, the rotation resistance of the rotating shaft 103 is reduced, and the rotating shaft 103 returns to the free rotation state.

[0032] In one embodiment, such as Figure 3 and Figure 8 As shown, a mounting sleeve 304 corresponding to the extrusion part 301 is installed on the rotating shaft 103. The extrusion end of the extrusion part 301 is a flexible structure. Both the extrusion end of the extrusion part 301 and the corresponding mounting sleeve 304 are provided with friction patterns to increase friction. The friction patterns can further increase the friction between the extrusion part 301 and the mounting sleeve 304, thereby further increasing the rotational resistance of the rotating shaft 103 and further locking the angle between the frames 1.

[0033] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
