A blackboard for mathematics teaching comprises: a body 1;

[0028] A slide groove 11, wherein the slide groove 11 is provided on one side of the body 1;

[0029] A moving frame 2, wherein the moving frame 2 is slidably connected to the inner side surface of the slide slot 11, a placement slot 22 is provided inside the moving frame 2, and a hook 23 is fixedly installed on the top of the inner side surface of the placement slot 22;

[0030] The measuring tool 3 is arranged on the front side of the main body 1 , and comprises a ruler 31 , a magnet 32 ​​and a handle 33 . The magnet 32 ​​is fixedly installed inside the ruler 31 , and the handle 33 is fixedly installed on the front side of the known ruler 31 .

[0031] A moving plate 24 is fixedly mounted on one side of the moving frame 2 , and a pushing plate 25 is fixedly mounted on one side of the moving plate 24 .

[0032] Limiting plates 12 are fixedly mounted on the top and bottom of the inner side of the slide slot 11 , and moving slots 21 are formed on the top and bottom of the moving frame 2 .

[0033] The limiting plate 12 is slidably connected to the inner side surface of the moving groove 21 .

[0034] When the moving frame 2 moves, the limiting plate 12 will slide on the inner side of the moving groove 21, so as to limit the moving frame 2 and increase the stability of the moving frame 2 when moving. In addition, the limiting plate 12 slides on the inner side of the moving groove 21, which can also prevent the moving frame 2 from completely sliding out of the inner side of the sliding groove 11.

[0035] The body 1 is a blackboard, and a metal plate is arranged inside the blackboard, so that the user can temporarily place the measuring tool 3 on the front of the body 1 when using it later, so that the user can take the measuring tool 3 later.

[0036] The measuring tool 3 can be a drawing ruler used for various drawings, and a groove is provided on the ruler 31 for hanging the measuring tool 3 on the hook 23 to facilitate subsequent users to take it;

[0037] A plurality of placement grooves 22 may be provided inside the movable frame 2 , and a plurality of hooks 23 may be installed on the inner side of the placement grooves 22 , so that a plurality of measuring tools 3 may be hung.

[0038] The working principle of a kind of mathematics teaching blackboard provided by the utility model is as follows:

[0039] When in use, when the user needs to use the measuring tool 3, the user can push the push plate 25, so that the push plate 25 drives the movable plate 24 away from the main body 1, so that the movable plate 24 drives the movable frame 2 to slide out from the inner side of the slide groove 11, and then the user can remove the measuring tool 3 from the top of the hook 23, and then the user can use the measuring tool 3 to draw mathematical geometry figures on the blackboard. After the drawing is completed, the user can temporarily place the measuring tool 3 on the top of the main body 1. At this time, the magnet 32 ​​and the main body 1 are magnetically attracted, so that the measuring tool 3 can be limited on the top of the main body 1. In this way, when using it later, the user can directly remove the measuring tool 3 for use.

[0040] Compared with the related art, the blackboard for mathematics teaching provided by the utility model has the following beneficial effects:

[0041] By cooperating with each other through structures such as the main body 1, the slide groove 11, the movable frame 2, the placement groove 22, the hook 23 and the measuring tool 3, the measuring tool 3 can be stored inside the main body 1 when in use, and the user does not need to carry a large number of measuring tools 3 into the classroom during class, thereby reducing the user's physical exertion. When drawing mathematical geometry figures later, the user does not need to move back and forth between the podium and the blackboard, thereby increasing the drawing efficiency and also increasing the usable area of ​​the podium.

[0044] A limiting groove 44 is defined inside the pushing plate 25 , and the positioning plate 41 is disposed on the inner side of the limiting groove 44 .

[0045] A combination lock 43 is sleeved on the outer side of the through slot 42 . The combination lock 43 is disposed on one side of the push plate 25 .

[0046] When the password lock 43 is in use, the user can set the password at will.

[0047] The working principle of a kind of mathematics teaching blackboard provided by the utility model is as follows:

[0048] When in use, the user pushes the pushing plate 25, so that the pushing plate 25 drives the movable plate 24 to move toward one side of the main body 1, until the movable plate 24 is attached to one side of the main body 1. At this time, the positioning plate 41 will be inserted into the inner side of the limiting groove 44. After that, the user can put the password lock 43 on the outer side of the through groove 42, and make the password lock 43 on one side of the pushing plate 25, so as to limit the positioning plate 41.

[0049] Compared with the related art, the blackboard for mathematics teaching provided by the utility model has the following beneficial effects:

[0050] Through the cooperation of the fixed plate 4, the positioning plate 41, the through groove 42, the password lock 43 and the limit groove 44 and other structures, when in use, the positioning plate 41 is inserted into the inner side of the limit groove 44, and then the password lock 43 is sleeved on the outer side of the through groove 42, so that the push plate 25 and the movable plate 24 can be limited and locked, avoiding the blackboard being set in the classroom and the measuring tool 3 being damaged by students taking it out to play at will.
