Detailed implementation manners

[0021] In order to further explain the technical solution of the present utility model, the following will be elaborated in detail through specific embodiments.

[0022] Please refer to Figures 1-3 , the present utility model provides a building design drawing measuring ruler, including a main scale 1, a protractor 2, an auxiliary scale 3 and a positioning mechanism 4. The upper end of the right side of the main scale 1 is rotatably connected to the protractor 2, the midpoint of the left side of the protractor 2 is rotatably connected to the auxiliary scale 3, and the tops of the main scale 1 and the auxiliary scale 3 are flush. The right side of the main scale 1 is attached to the left side of the auxiliary scale 3. Both the main scale 1 and the auxiliary scale 3 are made of metal. A positioning mechanism 4 is provided at the middle end of the auxiliary scale 3. The positioning mechanism 4 includes a sliding plate 41, a jack 42, a sliding member 43, a magnet block 44, a fixing assembly 45 and a pushing member 46. A jack 42 is vertically opened at the upper end of the sliding plate 41. Two groups of sliding members 43 are integrally formed on the upper and lower sides of the middle ends of the left and right sides of the sliding plate 41. Magnet blocks 44 are embedded in the middle ends of the left and right sides of the sliding plate 41. The magnet blocks 44 are located between the two groups of sliding members 43, and a rubber block is pasted on the inner side of the sliding member 43 for positioning the sliding member 43. A strip - shaped chute is opened at the middle end of the auxiliary scale 3, and the width of the strip - shaped chute is equal to the width of the sliding plate 41. A fixing assembly 45 is arranged inside the sliding plate 41. The lower end of the sliding plate 41 is vertically in threaded cooperation with the pushing member 46. The sliding plate 41 is embedded inside the strip - shaped chute at the middle end of the auxiliary scale 3, and is in sliding cooperation with the auxiliary scale 3 through the sliding members 43.

[0023] Wherein, the jack 42 and the pushing member 46 are on the same horizontal line, and the bottom end of the pushing member 46 is arc - shaped.

[0024] Specifically, the user can measure the line through the main scale 1. When the length of the main scale 1 is insufficient, the auxiliary scale 3 can be flipped to the left to extend the measurement length, and the protractor 2 can be used to assist in measuring the angle. When drawing an arc, the drawing pen can be fixed through the fixing assembly 45 first, and then the sliding plate 41 is pushed, so that the sliding plate 41 can move on the strip - shaped chute at the middle end of the auxiliary scale 3 through the sliding members 43. The rubber block on the inner side of the sliding member 41 can increase the friction between the sliding member 41 and the auxiliary scale 3 for auxiliary positioning, and the magnet block 44 can adsorb with the auxiliary scale to fix the position of the sliding plate 41. Then the drawing pen can be moved to a suitable position, and then the auxiliary scale is rotated in cooperation with the protractor, and arcs or circles with different angles can be drawn more conveniently.

[0025] Please refer toFigures 4-5 , the present utility model provides a building design drawing measuring ruler. The fixing component 45 includes a clamping plate 451, a push rod 452, a limiting plate 453, a guide rod 454, a spring 455 and a rubber pad 456. There is a clamping plate 451 arranged at the upper end inside the sliding plate 41. In the middle of the lower end of the clamping plate 451, a push rod 452 is integrally formed. The push rod 452 is in the shape of a rectangular plate as a whole, and the bottom end surface of the push rod 452 has a radian to cooperate with the pushing member 46. A limiting plate 453 is inserted into the lower end inside the sliding plate 41, and the push rod 452 vertically penetrates through the middle of the limiting plate 453. On both the left and right sides of the lower end of the clamping plate 451, a guide rod 454 is integrally formed, and the two groups of guide rods 454 respectively vertically penetrate through the left and right sides of the limiting plate 453 to guide the clamping plate 451. A spring 455 is arranged outside the push rod 452, and the clamping plate 451 and the limiting plate 453 are elastically connected through the spring 455 to reset the clamping plate 451. The top end of the clamping plate 451 is connected to the rubber pad 456. A through groove is opened on the lower side wall of the jack 42, and the rubber pad 456 at the top end of the clamping plate 451 can be embedded into the jack 42 through the through groove, facilitating the clamping and fixing of the drawing pen.

[0026] Among them, limiting blocks are integrally formed on both the front and back sides of the clamping plate 451, and the total width of the clamping plate 451 and the two groups of limiting blocks is wider than the width of the through groove on the lower side wall of the jack 42 to prevent the clamping plate 451 from detaching from the inside of the sliding plate 41.

[0027] Specifically, when it is necessary to fix the drawing pen, the user first inserts the drawing pen into the jack 42, and then rotates the pushing member 46. During the downward movement of the pushing member 46, the whole push rod 452 can be pushed to the right, and the push rod 452 can drive the whole clamping plate 451 to move to the right, so that the rubber pad 456 on the clamping plate 451 enters the inside of the jack 42. The positioning of the drawing pen can be realized through the rubber pad 456. During the movement of the clamping plate 451, the spring 455 will be stretched. When it is not necessary to fix the drawing pen, only need to reverse the pushing member 46 so that the bottom end of the pushing member 46 disengages from the push rod 452, and the clamping plate 451 can be reset by the pulling force of the spring 455. The guide rod 454 can make the horizontal movement of the clamping plate 451 more stable.

[0028] The above are only the preferred examples of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
