DETAILED DESCRIPTION

[0019] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] First embodiment

[0021] See also Figures 1 to 3 , Figure 1 This is a schematic diagram of the overall structure of the first embodiment of the present invention. Figure 2 This is the overall rear view of the first embodiment of the utility model. Figure 3 This utility model Figure 2 A magnified view of the local structure at point A.

[0022] The present invention provides a statistical drawing ruler, including a ruler body 101 and a locking type rotating drawing assembly, wherein the locking type rotating drawing assembly includes an identification groove 102, a rotating shaft 103, a housing 104, an angle groove 105, a fixed block 106, a pointer 107, a placement block 108, a placement cavity 109, a telescopic column 110, a rotating ruler 111, a circle drawing groove 112, a locking block 113 and a sliding block 114. The above-mentioned solution solves the problem that the circular ruler is fixed on the ruler and the rotating shaft of the central rotating circular ruler has no specific fixed component, thereby failing to accurately draw a circle, resulting in a significant reduction in the subsequent drawing quality. It can be understood that the above-mentioned solution can fix the ruler body 101 at a specified position when it is necessary to draw a circle or a sector, and then pull the telescopic column 110 to rotate the ruler body 101. The column 110 will use the telescopic column 110 as a fulcrum, and then the paintbrush will be inserted into the circle drawing groove 112 in the rotating ruler 111, and then the sliding block 114 will be slid to drive the locking block 113 to lock the current rotation angle of the rotating ruler 111, and then the rotating ruler 111 will be rotated, so that the paintbrush will use the telescopic column 110 as the center of the circle to draw a circle or a sector. At the same time, the rotating ruler 111 can also be rotated to cooperate with the ruler body 101 to measure the angle of the arc or circle. This will retain the original beneficial effects while actively and effectively solving the problem that the circular ruler is fixed on the ruler and the rotation axis of the center rotating circular ruler has no specific fixed component, so it will not be possible to draw a circle accurately, resulting in a significant reduction in the subsequent drawing quality.

[0023] In this specific embodiment, the identification groove 102 is fixedly connected to the ruler body 101 and is located inside the ruler body 101. The rotating shaft 103 is rotatably connected to the ruler body 101 and is located at one end of the ruler body 101. The housing 104 is rotatably connected to the rotating shaft 103 and is located on the outer surface of the rotating shaft 103. The angle groove 105 is detachably connected to the housing 104 and is located inside the housing 104. The rotating shaft 103 is the main functional structural component for rotating the rotating ruler 111, and the housing 104 is also a structural component for accommodating the locking block 113 while protecting the rotating shaft 103. The angle groove 105 and the identification groove 102 are functional auxiliary components for reminding people.

[0024] Among them, the fixed block 106 is detachably connected to the rotating shaft 103 and is located on one side of the rotating shaft 103. The pointer 107 is fixedly connected to the fixed block 106 and is located on the outer surface of the fixed block 106. The fixed block 106 and the pointer 107 will cooperate with the angle slot 105 to make it more intuitive for people to perform drawing operations.

[0025] Secondly, the placement block 108 is detachably connected to the rotating shaft 103 and is located on the side of the rotating shaft 103 away from the fixed block 106. The placement cavity 109 is fixedly connected to the placement block 108 and is located inside the placement block 108. The telescopic column 110 is detachably connected to the placement block 108 and is located inside the placement block 108, and the telescopic column 110 is arranged inside the placement cavity 109. The placement block 108 is the main structural component for placing the telescopic column 110, and the telescopic column 110 is a freely retractable fulcrum, which will effectively prevent the main body from shifting during the drawing process.

[0026] At the same time, the rotating ruler 111 passes through the housing 104 and is rotatably connected to the rotating shaft 103, and is located on the outer surface of the rotating shaft 103. The circle drawing groove 112 is detachably connected to the rotating ruler 111 and is located inside the rotating ruler 111. The rotating ruler 111 is a structural component that mainly rotates the drawn circle, and the circle drawing groove 112 is a cavity-type component used to facilitate people to adjust the diameter of the drawn circle.

[0027] In addition, the locking block 113 is slidably connected to the shell 104 and is located on the outer surface of the shell 104. The sliding block 114 is detachably connected to the locking block 113 and is located on the side of the locking block 113 away from the shell 104. The locking block 113 will not be able to move after being locked, thereby limiting the range of rotation of the rotating block on the rotating shaft 103, and the sliding block 114 is the main component for controlling the locking block 113.

[0028] When the present invention is used to draw a circle or a sector, the ruler body 101 is fixed at a specified position, and then the telescopic column 110 is pulled to use the telescopic column 110 as a fulcrum, and then the paintbrush is inserted into the circle drawing groove 112 in the rotating ruler 111, and then the sliding block 114 is slid to drive the locking block 113 to lock the angle of the current rotation of the rotating ruler 111, and then the rotating ruler 111 is rotated, so that the paintbrush will use the telescopic column 110 as the center of the circle to draw a circle or a sector. At the same time, the rotating ruler 111 can also be rotated to cooperate with the ruler body 101 to measure the angle of the arc or circle. This will retain the original beneficial effects while actively and effectively solving the problem that the circular ruler is fixed on the ruler and the rotation axis of the center rotating circular ruler has no specific fixed component, thereby making it impossible to draw a circle accurately, resulting in a significant reduction in the subsequent drawing quality.

[0029] Second embodiment

[0030] See also Figure 4 , Figure 4 It is a schematic diagram of the overall structure of the second embodiment of the present utility model.

[0031] On the basis of the first embodiment, a statistical plotting ruler of the present invention further includes a storage component, which includes a storage slot 201 , a telescopic plate 202 and a handle 203 .

[0032] According to this specific embodiment, the storage slot 201 is fixedly connected to the ruler body 101 and is located inside the ruler body 101, and the storage slot 201 is arranged below the identification slot 102, the telescopic plate 202 is detachably connected to the ruler body 101 and is located inside the ruler body 101, and the telescopic plate 202 is arranged inside the storage slot 201, and the handle 203 is detachably connected to the telescopic plate 202 and is located on a side of the telescopic plate 202 away from the ruler body 101. The storage slot 201 is the main place for storing paintbrushes. When people finish drawing, they often do not pay much attention to the storage of paintbrushes and are prone to losing them. After drawing the statistical chart, they place the paintbrushes in the storage slot 201 and then pull the handle 203 to extend the telescopic plate 202 to collect and store the paintbrushes, thereby effectively preventing the paintbrushes from being lost.

[0033] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the utility model.
