Example 1

Referring to fig. 1 to 5, the present embodiment provides an auxiliary device for drawing a general teaching set square, which includes a set square body 1, wherein a hidden groove 101 is formed on each side of the set square body 1, a mounting groove 102 is formed in the middle of the inside of each hidden groove 101, and the hidden grooves 101 and the mounting grooves 102 are communicated with each other. In this embodiment, the internally mounted of mounting groove 102 has spring 3 and connecting piece 4 of connecting auxiliary chi 2, wherein connecting piece 4 is located the inside centre of mounting groove 102, spring 3 is located the both sides of connecting piece 4, spring 3's one end simultaneously, the one end of connecting piece 4 all is connected with mounting groove 102's inside one side, spring 3's the other end, the other end of connecting piece 4 all is connected with auxiliary chi 2 one side inwards, auxiliary chi 2 sets up in the inside of hiding groove 101, wherein auxiliary chi 2 has the function of supplementary drawing. It is noted that the depth of the hidden groove 101 is greater than the width of the auxiliary scale 2.

Specifically speaking, when the set square body 1 is not in use, the auxiliary ruler 2 can be located inside the hidden groove 101, and the side edge of the auxiliary ruler is not flush with the side edge of the set square body 1, so that the dust on the auxiliary ruler 2 can not adhere to the side edge of the set square body 1, and can be drawn by means of the auxiliary ruler 2, and the possibility that the dust falls on the side edge of the set square body 1 is reduced. When the auxiliary scale 2 is extended for use, the spring 3 is in a stretching state, and when the auxiliary scale is not used, the spring 3 can reset the auxiliary scale 2, so that the auxiliary scale 2 is stably hidden in the hidden groove 101. That is, the auxiliary scale 2 can be always located in the hidden groove 101, and can be moved into or out of the hidden groove 101.

In this embodiment, the connecting member 4 includes a pushing block 41 and a top post 42. Wherein promote fixed connection between one side that piece 41 inwards and the inside side of mounting groove 102, promote one side that piece 41 outwards and one side fixed connection that the fore-set 42 inwards, fore-set 42 outwards one side and the inside one side fixed connection that supplementary chi 2 inwards. Meanwhile, a first inclined surface 411 is formed on the inward side of the pushing block 41, and the first inclined surface 411 is connected with the lower end of the pressing component 5.

Meanwhile, the pressing component 5 used for driving the auxiliary ruler 2 to move is installed at the upper end of the triangular plate body 1, the sliding hole 103 is formed in the upper end of the triangular plate body 1, and the lower end of the pressing component 5 penetrates through the sliding hole 103 to be connected with one inward side of the connecting piece 4. It is worth noting that the number of the sliding holes 103 and the number of the pressing assemblies 5 are the same as the number of the sides of the triangle body 1, and one pressing assembly 5 is arranged on each side of the triangle body 1, and the hole diameter of the sliding hole 103 is not smaller than the width of the pressing assembly 5, and the sliding hole 103 and the pressing assembly 5 are located on the same vertical plane. It should be noted that the upper end of the sliding hole 103 is provided with a circular hole 104, the hole diameter of the circular hole 104 is larger than the hole diameter of the sliding hole 103, and the hole diameter of the circular hole 104 is not smaller than the width of the pressing plate 51.

In the present embodiment, the pressing assembly 5 includes a pressing plate 51 and a driving block 53. The pressing disc 51 is positioned at the upper end of the side edge of the triangle board body 1, the driving block 53 is positioned in the mounting groove 102, and the pressing disc 51 and the driving block 53 are connected through the connecting column 52 and the sliding hole 103. Meanwhile, the lower end of the driving block 53 is provided with a second inclined surface 531, and the second inclined surface 531 is matched with the first inclined surface 411. It should be noted that the upper end of the sliding hole 103 is provided with a circular hole 104, the hole diameter of the circular hole 104 is larger than the hole diameter of the sliding hole 103, and the hole diameter of the circular hole 104 is not smaller than the width of the pressing plate 51. Note that the circular hole 104 is used for the pressing plate 51 to move up and down in the circular hole 104. That is, a person holds the triangle board body 1 for use, the pressing plate 51 can be operated conveniently, and the circular hole 104 provides a space for the movement of the pressing plate 51.

Specifically, when the pressing plate 51 is pressed downward, the connecting rod 52 can move along the sliding hole 103, and the driving block 53 moves downward, and the second inclined surface 531 can contact with the first inclined surface 411 and slide along the first inclined surface, so that the driving block 53 can drive the pushing block 41 to push the auxiliary ruler 2. That is, when the push block 41 moves in cooperation with the driving block 53, the top post 42 can move together, thereby moving the auxiliary scale 2 out of the interior of the hidden slot 101.

In this embodiment, specifically, when the set square body 1 is used, a teacher holds the set square body 1 on a blackboard, the palm can press the pressing disc 51, at this time, the pressing disc 51 moves in the circular hole 104, the connecting column 52 moves along the sliding hole 103, and then the driving block 53 moves downward, then under the cooperation of the driving block 53 and the pushing block 41, the first inclined plane 411 contacts with the second inclined plane 531, so that the driving block 53 can drive the pushing block 41 to move, the auxiliary ruler 2 can be pushed out from the set square body 1, the auxiliary ruler 2 stretches the spring 3 along the hidden groove 101 to move, so that the teacher can draw chalk along the auxiliary ruler 2 when using the set square body 1, and after finishing, the auxiliary ruler 2 can be located in the hidden groove 101 under the action of the spring 3, in this way, when using the set square body 1, no dust adheres to the side edge of the set square body 1, the carrying effect of the triangle body 1 is improved. Simultaneously because set-square body 1 need place and use on the blackboard, the contact surface of set-square body 1 and blackboard can be the concavity, reduces the area of contact of set-square body 1 and blackboard, has reduced the weight and the material of set-square body 1, and is difficult for making the chalk word on the blackboard rub on set-square body 1.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
