[0035] Please refer to Figure 1 and Figure 2 A splicable teaching letter card in a preferred embodiment of the utility model includes a transparent card frame 100, a letter board 200 and a card board structure 300.

[0036] The transparent card frame 100 has a slot 110 with an upper opening, a yielding opening 111 is provided at the rear side of the slot 110, a first splicing structure is provided on the right side of the transparent card frame 100, and a second splicing structure corresponding to the first splicing structure is provided on the left side of the transparent card frame 100. The two transparent card frames 100 can be spliced ​​left and right by connecting the first splicing structure with the second splicing structure; the front surface of the letter board 200 has characters, and the characters can be English letters; of course, when other information is required, the characters can also be numbers or Chinese characters. The letter board 200 can be made of paper material. The letter board 200 is inserted into the slot 110, and the letter board 200 and the transparent card frame 100 are detachable structures. After the letter board 200 is damaged, it can be directly disassembled and replaced.

[0037] The clamping plate structure 300 is installed at the rear side of the transparent card frame 100 and can apply a forward force to the letter board 200 from the yield opening 111 , thereby clamping the letter board 200 in cooperation with the front side wall of the slot 110 .

[0038] The utility model provides a splicable teaching letter card. A letter board 200 is inserted into a slot 110 and fixed in the slot 110 by a card board structure 300, so that the letter board 200 is surrounded by a transparent card frame 100, and the letter board 200 is protected to prevent it from being easily damaged. The first splicing structure and the second splicing structure on the left and right sides of the transparent card frame 100 are used to realize the splicing between the transparent card frames 100, thereby realizing the splicing between the letter boards 200, so that characters can be put in the hand and spliced ​​in sequence, and it is not easy to be disrupted after the splicing is completed.

[0039] Reference Figures 1 to 5In some embodiments of the utility model, the first splicing structure is a groove 120 arranged on the right side of the transparent card frame 100, and the second splicing structure is a protrusion 130 arranged on the left side of the transparent card frame 100. The protrusion 130 is adapted to the groove 120, and the positioning splicing of the two transparent card frames 100 is achieved by inserting the protrusion 130 into the groove 120.

[0040] Reference Figure 3 and Figure 5 In a further embodiment of the utility model, a first magnetic attraction structure 140 is installed on the protrusion 130, and a second magnetic attraction structure 150 corresponding to the first magnetic attraction structure 140 is installed on the right side of the transparent card frame 100, and there is a magnetic attraction between the first magnetic attraction structure 140 and the second magnetic attraction structure 150. The first magnetic attraction structure 140 and the second magnetic attraction structure 150 are both permanent magnets, so that the attraction of the first magnetic attraction structure 140 and the second magnetic attraction structure 150 is used to make the two transparent card frames 100 have a certain force when splicing so that the two are kept in a spliced ​​state when they are not subjected to an external force greater than the attraction, so that the splicing of the two is stable, and when disassembling, it is only necessary to use force to pry the two apart, which does not affect the convenience of disassembly.

[0041] Reference Figure 3 and Figure 5In a further embodiment of the utility model, the upper and lower end surfaces of the protrusion 130 are provided with a first embedding groove 141, the first magnetic structure 140 is provided with two and respectively embedded in the two first embedding grooves 141, the upper and lower end surfaces of the right side of the transparent sign frame 100 are provided with a second embedding groove 151, the second magnetic structure 150 is provided with two and respectively embedded in the two second embedding grooves 151, the second magnetic structure 150 is highly aligned with the first magnetic structure 140, and the first embedding groove 141 and the second magnetic structure 151 are used to realize the positioning and installation of the first magnetic structure 140 and the second magnetic structure 150. It can be understood that in order to ensure stable installation, the first magnetic structure 140 and the second magnetic structure 150 can be embedded in the first embedding groove 141 and the second embedding groove 151 by interference fit. Moreover, the openings of the first embedding groove 141 and the second embedding groove 151 are both set upward or downward, and the magnetic attraction force of the first magnetic attraction structure 140 and the second magnetic attraction structure 150 is in the horizontal left and right direction, and the magnetic attraction force will not exert a tendency for the first magnetic attraction structure 140 and the second magnetic attraction structure 150 to move away from the first embedding groove 141 and the second embedding groove 151, thereby preventing the first magnetic attraction structure 140 and the second magnetic attraction structure 150 from being separated from the first embedding groove 141 and the second embedding groove 151 under the action of the magnetic attraction force, thereby improving the stability of the structure. It can be understood that in order to further improve the stability of the structure, after the first magnetic attraction structure 140 and the second magnetic attraction structure 150 are embedded in the first embedding groove 141 and the second embedding groove 151, sealant can be poured into the openings of the first embedding groove 141 and the second embedding groove 151, thereby sealing the openings of the first embedding groove 141 and the second embedding groove 151, and further improving the installation stability of the first magnetic attraction structure 140 and the second magnetic attraction structure 150.

[0042] Reference Figure 4 and Figure 6 In some embodiments of the present invention, the card structure 300 is an elastic tongue connected to the bottom side wall of the clearance opening 111, the lower end of the elastic tongue is connected to the bottom side wall of the clearance opening 111, and the upper end can be elastically movable forward and backward, thereby applying an elastic pressing force forward to the letter board 200 inserted into the slot 110. The letter board 200 is pressed by the elastic activity of the free end of the upper end of the elastic tongue, and the letter board 200 does not need to be fixed by fasteners during installation and is also easy to disassemble.

[0043] Reference Figure 4 and Figure 6 In a further embodiment of the utility model, a rearward-tilting portion 310 is provided at the upper end of the elastic depressing tongue, and the thickness of the depressing portion 310 gradually becomes thinner from top to bottom, so that structural interference is avoided when the letter board 200 is inserted. The rearward-tilting portion 310 and the thinning treatment of the upper end can be used to facilitate the direct insertion of the letter board 200, without the need to manually hook the elastic depressing tongue backward and then insert it into the letter board 200.

[0044] Reference Figure 4 and Figure 6 In a further embodiment of the present invention, the transparent card frame 100, the elastic tongue depressor, and the raised portion 310 are connected as one body. It is understandable that the transparent card frame 100 is made of a transparent material, which will not affect the letter board 200 from displaying characters outward. The transparent card frame 100 can be made of one or more materials such as polymethyl methacrylate (commonly known as acrylic or organic glass), polycarbonate, and polyethylene terephthalate. The plastic material is durable and corrosion-resistant, and can effectively protect the letter board 200. In addition, the transparent plastic has a certain elasticity, which meets the elastic deformation requirements of the elastic tongue depressor.

[0045] Reference Figure 4 In some embodiments of the present invention, a horizontal plate 160 is across the middle of the opening 111, and the front side of the horizontal plate 160 is flush with the rear side wall of the slot 110. The horizontal plate 160 can limit the middle of the letter plate 200, so that the middle of the letter plate 200 will not arch backwards and affect the appearance of the characters, and can ensure that the middle position of the letter plate 200 is well fitted with the front side wall of the slot 110.

[0046] Reference Figure 4 In some embodiments of the present invention, a third embedding groove 161 is provided on the upper end surface of the horizontal plate 160, and a magnet block 162 is installed in the third embedding groove 161. By providing the magnet block 162, the transparent card frame 100 can be adapted to the magnetic blackboard and can be directly magnetically attached to the blackboard for display.

[0047] Of course, in some other embodiments, the third embedding groove 161 and the magnet block 162 may not be provided, which can be suitable for a scenario where a group of people plays group games around a study table.

[0048] Reference Figure 3 In some embodiments of the present invention, the upper edge of the rear side of the slot 110 is chamfered to facilitate the insertion of the letter board 200.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
