Description

Technical Field

[0001] The utility model relates to the technical field of notice boards, in particular to a notice board which is easy to replace. Background Art

[0002] A sign is a sign used to draw attention, remind, or warn people of specific information, and thereby communicate. Signs have a slot for paper, typically A4 paper, to display the information. To facilitate insertion and removal, the slot is larger than the paper's thickness. This lacks support for the paper, making it prone to bending and deformation, which can affect its usability.

[0003] In order to solve the problems existing in the above-mentioned notice board, the notice board is set to be a split type, which includes a fixed frame and a movable frame. Magnets with opposite magnetic properties are respectively provided on the fixed frame and the movable frame, and the magnets are used to clamp the paper. However, when changing the paper, the fixed frame is fixed to the wall. When the fixed frame and the movable frame are coordinated, the paper is very likely to change position, making it inconvenient to replace. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a signboard with high stability, simple structure and easy replacement.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A signboard that is easy to replace, comprising a fixed frame and a movable frame, wherein the fixed frame is fixedly mounted on a wall by expansion screws, the movable frame is made of a transparent plastic material, and the movable frame cover is arranged on the outside of the fixed frame;

[0007] The movable frame is provided with an embedding groove, a fixed magnet is fixed in the embedding groove, the fixed magnet attracts the movable magnet, a paper is clamped between the fixed magnet and the movable magnet, the magnetic properties of the fixed magnet and the movable magnet are opposite, and the fixed frame is provided with a clearance hole facing the movable magnet; both sides of the fixed frame and the movable frame are connected by a connecting structure.

[0008] During installation, the fixed frame is fixed to the wall with expansion screws, the fixed magnets are separated from the movable magnets, paper is placed on the movable frame, and the fixed magnets are then attracted to the movable magnets. The fixed and movable magnets are positioned on either side of the paper, forming a stable clamp for the paper. After the paper is placed, the movable frame cover is placed outside the fixed frame and connected via a connecting structure to improve stability. The movable frame is made of transparent plastic material to facilitate the display of information on the paper.

[0009] Wherein, the movable frame has an inverted U-shaped cover, and the cover is arranged on the outside of the fixed frame.

[0010] The connection structure includes two sliding rods fixedly mounted on the outside of the fixing frame, and the cover shell is provided with a sliding groove that is slidably matched with the sliding rods, and the sliding groove is in an inverted L shape.

[0011] Wherein, a bracket is fixed to the lower end of the movable frame, and the bracket is located between the movable frame and the fixed frame.

[0012] Wherein, the said giving way hole is a waist-shaped hole.

[0013] In summary, the notice board that is easy to replace has the advantages of simple operation for replacing paper and stable paper placement. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 The utility model is a structural schematic diagram of a notice board that is easy to replace.

[0017] The present invention is further described in detail below with reference to the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional terms such as "upper, lower" and "top, bottom" are generally based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. Unless otherwise indicated, these directional terms do not indicate or imply that the devices or components referred to must have a specific direction or be constructed and operated in a specific direction, and therefore should not be understood as limiting the scope of protection of the present invention; the directional terms "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0018] like Figure 1-3 As shown, a signboard that is easy to replace includes a fixed frame 1 and a movable frame 2. The fixed frame is fixed to the wall by expansion screws, the movable frame is made of transparent plastic material, and the movable frame cover is provided on the outside of the fixed frame;

[0019] The movable frame is provided with an embedding groove, in which a fixed magnet 3 is fixed. The fixed magnet attracts a movable magnet (not shown), and paper is clamped between the fixed magnet and the movable magnet. The magnetic properties of the fixed magnet and the movable magnet are opposite, and the fixed frame is provided with a clearance hole 4 facing the movable magnet; both sides of the fixed frame and the movable frame are connected by a connecting structure.

[0020] During installation, the fixed frame is fixed to the wall with expansion screws, the fixed magnets are separated from the movable magnets, paper is placed on the movable frame, and the fixed magnets are then attracted to the movable magnets. The fixed and movable magnets are positioned on either side of the paper, forming a stable clamp for the paper. After the paper is placed, the movable frame cover is placed outside the fixed frame and connected via a connecting structure to improve stability. The movable frame is made of transparent plastic material to facilitate the display of information on the paper.

[0021] Specifically, the movable frame is made of acrylic board.

[0022] During implementation, the movable frame has an inverted U-shaped cover 5, which is arranged on the outside of the fixed frame. The structure is simple, and the fixed frame can support the cover.

[0023] In practice, the connection structure includes two slide bars 6 fixedly mounted on the outside of the fixed frame. The cover is provided with an inverted L-shaped slot 7 that slidably engages with the slide bars. The slide bars and slot connect the fixed frame and the movable frame, and the inverted L-shaped slot allows the cover to be stably placed on the outside of the fixed frame by gravity.

[0024] During implementation, a bracket 8 is fixed to the lower end of the movable frame, and the bracket is located between the movable frame and the fixed frame, so as to facilitate positioning and supporting of the paper.

[0025] Specifically, the thickness of the bracket and the fixing frame are the same as the width of the cover.

[0026] During implementation, the clearance hole is a waist-shaped hole to avoid interference between the movable magnet and the fixing frame.

[0027] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims and their equivalents, the present invention is intended to include such modifications and variations.
