Fig. 2 is a right view of the English line drawing teaching aid.
Fig. 3 is a left view of the English line drawing teaching aid.
Detailed Description
Example 1
Referring to fig. 1 to 3, the English line drawing teaching aid comprises a main body 1, wherein four chalk holes 2 are formed in one side of the main body 1, a locking screw 3 is arranged on the side face of each chalk hole 2, a handle 4 is arranged on the back of the main body 1, a horizontal indicator 5 is arranged at the position of the handle 4, liquid in the horizontal indicator 5 is colored liquid (refer to the prior art, for example, the colored liquid is prepared by adding red ink into water), and a horizontal marking line 51 is arranged on the horizontal indicator 5.
When the line drawing device is used, the line drawing device is in a horizontal state as much as possible by checking the horizontal indicator, and the horizontal indicator is provided with the internal colored liquid and the horizontal marking line, so that the line drawing device is convenient to use and check and beneficial to use of the line drawing device.
In an embodiment, the level indicator 5 has a housing 5a, and the housing 5a has an inner cavity therein, wherein the thickness of the housing 5a is uniform, and the housing 5a and the inner cavity are in a square shape. In the embodiment, two horizontal marking lines 51 are provided at one side of the housing 5a, the two horizontal marking lines 51 are in a cross shape (the amount of liquid added in the horizontal indicator is half of the volume of the inner cavity, and accordingly, the horizontal marking lines arranged in the transverse direction are arranged in the middle (as shown in fig. 3, the horizontal marking lines arranged in the transverse direction are the connecting lines between the middle points of the vertical lines at the left side of the housing and the middle points of the vertical lines at the right side of the housing), and the horizontal marking lines arranged in the vertical direction are also arranged in the middle). The design is beneficial to the use and adjustment of the line drawing device.
In the embodiment, the handle 4 is connected to the body 1 by a bolt 41. The handle can be adjusted to be horizontal or vertical and then fixed through the bolt. The above design makes the handle suitable for different operating habits.
In the embodiment, a spring member 21 is provided in the chalk hole 2. In a natural state, the end of the spring member is flush with the inlet of the chalk hole (the other end of the spring member is connected to the bottom of the chalk hole). The design can avoid the situation that the foreign matters enter the hole when the chalk is idle on the one hand, and on the other hand, the chalk is convenient to mount and adjust.
In the embodiment, the locking screw 3 is arranged near the inlet side of the chalk hole 2. The design is beneficial to the use of chalk.
In the embodiment, the locking screw 3 is made of wood (or rubber). The design is favorable for locking the chalk, and the damage to the chalk is small.
Example 2
The basic scheme is the same as embodiment 1, and the difference lies in that in order to facilitate the dismounting of the bolt, the middle part of the handle is provided with a handle through hole. The tool can be passed through the handle through-hole and then drive the bolt (in this embodiment, the bolt is a socket head cap bolt).
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment, and all technical solutions belonging to the principle of the present invention belong to the protection scope of the present invention. Modifications to the disclosed embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
