Description

Technical Field

[0001] This utility model relates to the field of wall charters, specifically a new type of teaching wall charter. Background Technology

[0002] A picture hanger is a device that makes it easy to hang pictures. Pictures used in teaching, such as pinyin pictures and number pictures, are generally used for students to point to and read in class, eliminating the need to copy them onto the blackboard, thereby improving teaching efficiency.

[0003] In existing technologies, picture hangers generally use torsion springs or other clamping mechanisms that pinch and open to clamp the top edge of the picture. This method of operation has the potential to further improve the efficiency of changing pictures. Utility Model Content

[0006] As a further embodiment of this utility model: the clamping mechanism includes a rotating shaft rotatably mounted on both ends of the inner wall of the rotating groove, and a downwardly inclined short arm integrally formed on the outer periphery of the rotating shaft near one end, and a pressure rod fixedly mounted on the end of the short arm away from the rotating shaft.

[0007] As a further embodiment of this utility model: the clamping mechanism further includes a long arm integrally formed on the outer periphery of the rotating shaft and away from the short arm, and a counterweight rod integrally formed at the end of the long arm away from the rotating shaft.

[0008] As a further embodiment of this utility model: the bottom of the inner wall of the rotating groove is integrally formed with an arc-shaped groove, the center of the arc-shaped groove coincides with the center of the rotating shaft, and the radius of the arc-shaped groove is equal to the radius of the rotation trajectory of the pressure rod.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. By setting up a clamping mechanism, the design of the clamping mechanism allows it to be opened with the application of a small amount of force, making it convenient to open and improving the efficiency of changing paintings. Attached Figure Description

[0015] 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.

[0016] Please see Figures 1-3 In this embodiment of the utility model, a novel teaching chart holder includes a handle 1 with a through hole 2 inside. The bottom end of the handle 1 is integrally formed with a long strip-shaped hanging rod 3. The bottom end of the hanging rod 3 has an upwardly recessed connecting groove 4. The connecting groove 4 extends along the length direction of the hanging rod 3, and both ends and the bottom end of the connecting groove 4 are open. The front end of the hanging rod 3 has a rotating groove 5. The front end and the rear end of the rotating groove 5 are open. A clamping mechanism is installed inside the rotating groove 5 along the length direction of the hanging rod 3.

[0017] In this embodiment: First, a bolt is fixed to the wall, and then the through hole 2 is hung on the bolt. When hanging the teaching picture (such as a pinyin picture or a number picture), an upward thrust is applied to the part of the clamping mechanism located outside the hanging rod 3. At this time, the part of the clamping mechanism located inside the hanging rod 3 rotates downward. Then, the top of the teaching picture is inserted into the connecting groove 4. After insertion, the thrust is removed, and the clamping mechanism resets under gravity. The clamping mechanism part located inside the hanging rod 3 rotates upward. At this time, the clamping mechanism located inside the hanging rod 3 cooperates with the inner wall of the connecting groove 4 to clamp the top edge of the teaching picture. This method has a convenient picture hanging effect.

[0018] Please refer to this carefully. Figure 2 and Figure 3 The clamping mechanism includes a rotating shaft 6 rotatably mounted on both ends of the inner wall of the rotating groove 5. A short arm 7 inclined downward is integrally formed on the outer periphery of the rotating shaft 6. A pressure rod 9 is fixedly installed on the end of the short arm 7 away from the rotating shaft 6. The clamping mechanism also includes a long arm 8 integrally formed on the outer periphery of the rotating shaft 6 and away from the short arm 7. A counterweight rod 10 is integrally formed on the end of the long arm 8 away from the rotating shaft 6.

[0019] In this embodiment: when clamping the teaching picture, an upward pushing force is applied to the counterweight rod 10. At this time, the counterweight rod 10 drives the rotating shaft 6 to rotate through the long arm 8. The rotating shaft 6 simultaneously drives the short arm 7 to drive the pressure rod 9 to rotate downward. At this time, the outer periphery of the pressure rod 9 separates from the inner wall of the connecting groove 4. Then, the teaching picture is inserted between the connecting groove 4 and the pressure rod 9. After that, the force applied to the counterweight rod 10 is removed. At this time, the counterweight rod 10 returns to its original position under gravity. At this time, the pressure rod 9 rotates upward to return to its original position, and clamps the top edge of the teaching picture with the inner wall of the connecting groove 4.

[0020] Please refer to this carefully. Figure 3 The bottom of the inner wall of the rotating groove 5 is integrally formed with an arc-shaped groove 11. The center of the arc-shaped groove 11 coincides with the center of the rotating shaft 6, and the radius of the arc-shaped groove 11 is equal to the radius of the rotation trajectory of the pressure rod 9.

[0021] In this embodiment: when the counterweight rod 10 is subjected to force and rotates upward, the pressure rod 9 rotates downward. During the rotation of the downward rotating pressure rod 9, it comes into contact with the arc-shaped groove 11. This design can avoid interference of the pressure rod 9 during the rotation.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
