Description

Technical Field

[0001] The utility model relates to magnetic whiteboard accessories, and particularly to a magnetic clip for whiteboard symbols. Background Art

[0002] Magnetic whiteboard symbols are common magnetic whiteboard accessories. The usage method of magnetic whiteboard symbols is to magnetically adsorb on the magnetic whiteboard for indicating and marking to help listeners better understand the blackboard writing (such as characters, maps or background pictures). Currently, existing magnetic whiteboard symbols are all of double-layer structure, which are composed of a symbol thin sheet and a magnetic stone thin sheet on the back of the symbol body. The symbol thin sheet and the magnetic stone thin sheet are adhesively fixed. Since the magnetic stone thin sheet is customized according to the shape and size of the symbol body and needs to go through an adhesive process, there are problems such as high production cost, low operation efficiency, and lack of flexibility. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a new magnetic clip for whiteboard symbols different from the double-layer structure magnetic whiteboard symbols.

[0004] To achieve the above purpose, the technical solution of the utility model is as follows: A magnetic clip for whiteboard symbols includes a clip body and a symbol body. The clip body has a clip backboard and a clip magnet. There is a magnet accommodating seat on the back of the clip backboard. The magnet accommodating seat has a seat central column and a seat peripheral wall surrounding the seat central column. The seat central column and the seat peripheral wall together form a seat annular groove. The opening of the seat annular groove faces away from the clip backboard. The clip magnet is in an annular structure and is embedded inside the seat annular groove. There is an L-shaped clamping rod on the front of the clip backboard. The L-shaped clamping rod has a vertical clamping rod part and a horizontal clamping rod part. The vertical clamping rod part is parallel to the clip backboard. The symbol body is between the vertical clamping rod part and the clip backboard. The vertical clamping rod part and the clip backboard are jointly used to clamp and fix the symbol body. The beneficial effects are at least as follows: Through the clip magnet, the magnetic clip for whiteboard symbols (the clip body and the symbol body) can be fixed on the magnetic whiteboard in a magnetic adsorption manner. The vertical clamping rod part and the clip backboard jointly clamp and fix the symbol body, omitting the adhesive process, and the processing is more simple and efficient. Moreover, the vertical clamping rod part and the clip backboard can clamp symbol bodies with different structures. Also, since the vertical clamping rod part has a certain elastic deformation ability, the vertical clamping rod part and the clip backboard can also clamp symbol bodies with different thicknesses.

[0005] As a preferred solution for the magnetic clip of the whiteboard symbol, a central post flange extending radially outward is formed at the top of the central post of the receiving seat, which is used to limit the separation of the clip magnet from the annular groove of the receiving seat. Preferably, the central post flange is formed by a hot stamping process. The beneficial effects are at least as follows: preventing the clip magnet from separating from the annular groove of the receiving seat.

[0006] As a preferred solution for the magnetic clip of the whiteboard symbol, the vertical part of the clamping rod has a vertical part protrusion facing the clip back plate. Preferably, the vertical part protrusion has an arc chamfer. The beneficial effects are at least as follows: facilitating the smooth insertion of the symbol body into the insertion gap.

[0007] In addition to the technical problems solved by the present invention, the technical features constituting the technical solutions, and the beneficial effects brought by these technical features of the technical solutions described above, other technical problems that the present invention can solve, other technical features included in the technical solutions, and the beneficial effects brought by these technical features will be further described in detail in conjunction with the accompanying drawings.

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings through specific embodiments. It should be noted here that the description of these embodiments is for helping to understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. Embodiment 1

[0014] See Figure 1, the figure shows a whiteboard symbol magnetic clamp. The whiteboard symbol magnetic clamp can be fixed on a magnetic whiteboard by magnetic attraction. The whiteboard symbol magnetic clamp includes: a clamp body 1 and a symbol body 2. The clamp body 1 and the symbol body 2 are fixedly connected in a detachable manner.

[0015] The clamp body 1 comprises a clamp back plate 11 and clamp magnets (not shown).

[0016] The clamp back plate 11 is a plastic part, which is light and easy to process. In this embodiment, the clamp back plate 11 is a trapezoidal structure.

[0017] See also Figure 2 and Figure 3 , there is a magnetic steel receiving seat 12 on the back side of the clamp back plate 11. The magnetic steel receiving seat 12 has a receiving seat center column 121 and a receiving seat peripheral wall 122 surrounding the outer periphery of the receiving seat center column 121. The receiving seat center column 121 and the receiving seat peripheral wall 122 together form a receiving seat ring groove 123. The opening of the receiving seat ring groove 123 faces away from the clamp back plate 11. The clamp magnetic steel is annular in structure. The clamp magnetic steel is embedded in the receiving seat ring groove 123.

[0018] Furthermore, a central column flange (not shown) extending radially outward is formed at the top of the central column 121 of the receiving seat. The central column flange and the clamp back plate 11 are respectively at opposite ends of the clamp magnetic steel. The central column flange is used to position the clamp magnetic steel to prevent the clamp magnetic steel from escaping from the receiving seat ring groove 123.

[0019] In a specific implementation, the clamp back plate 11 is extended in length along the left-right direction. There are two magnetic steel receiving seats 12. One of the magnetic steel receiving seats 12 is located in the left half of the clamp back plate 11. The other magnetic steel receiving seat 12 is located in the right half of the clamp back plate 11.

[0020] In a specific implementation, the center column flange is formed by a hot stamping process.

[0021] The front side of the clamp back plate 11 is provided with an L-shaped clamping rod 13. The L-shaped clamping rod 13 has a clamping rod vertical portion 131 and a clamping rod transverse portion 132. The clamping rod vertical portion 131 is parallel to the clamp back plate 11. An insertion gap 14 is provided between the clamping rod vertical portion 131 and the clamp back plate 11. The clamping rod transverse portion 132 is perpendicular to the clamp back plate 11. The clamping rod vertical portion 131 is fixed to the front side of the clamp back plate 11 through the clamping rod transverse portion 132.

[0022] The symbol body 2 is between the vertical part 131 of the clamping rod and the back plate 11 of the clip. The vertical part 131 of the clamping rod and the back plate 11 of the clip are jointly used to clamp and fix the symbol body 2. When clamping and fixing, the symbol body 2 is preferably placed on the horizontal part 132 of the clamping rod and supported by the horizontal part 132 of the clamping rod to prevent it from falling. Further, the vertical part 131 of the clamping rod has a vertical part protrusion 1311 facing the back plate 11 of the clip. The vertical part protrusion 1311 abuts against the symbol body 2. Through the vertical part protrusion 1311, the symbol body 2 can be better clamped. Furthermore, the vertical part protrusion 1311 has an arc chamfer 1312, which is beneficial for the symbol body 2 to be smoothly inserted into the insertion gap 14.

[0023] In specific implementation, the number of the L-shaped clamping rods 13 is two. One of the L-shaped clamping rods 13 is in the left half area of the back plate 11 of the clip. The other L-shaped clamping rod 13 is in the right half area of the back plate 11 of the clip. The two L-shaped clamping rods 13 face the same direction.

[0024] In specific implementation, the symbol body 2 can be customized by the user. The manufacturing methods such as card printing, plastic sheet cutting, etc. can all be adsorbed to the magnetic whiteboard through the clip body 1, and the user can add the desired symbol elements without limitation.
