Description

Technical Field

[0001] The utility model relates to the technical field of tool rulers, in particular to a mechanical design tool ruler. Background Art

[0002] Mechanical design is the conception, analysis and calculation of the working principle, structure, operation mode, force and energy transmission mode, material, shape and size of each part, lubrication method, etc. of the machine according to the requirements of use, and converts them into specific descriptions as the working principle based on manufacturing. In the design process, the accuracy of drawing determines the adaptability of mechanical parts. Therefore, the precise drawing of mechanical parts with the help of tool rulers can make the mechanical parts meet production requirements.

[0003] Currently, when mechanical parts are drawn using a ruler, the ruler is placed on the drawing paper, and then a drawing pen is used to draw lines along the ruler. Lines of different lengths are drawn according to the drawing requirements. The ruler can be used to confirm not only the direction of the lines but also the length of the lines. However, when the line to be drawn is long, the ruler is used to draw from the scale starting point to the end point of the ruler. When the drawing is completed, the ruler is moved until the scale starting point coincides with the drawing end point, and then the drawn line can be extended until the drawing length is reached. However, when the ruler moves toward the end point of the line, it is easy to tilt due to the shaking of the ruler, resulting in the ruler being unable to be parallel to the drawn line after movement, which increases the difficulty of drawing mechanical parts and reduces the accuracy of drawing mechanical parts.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1-6 The present invention provides an embodiment of a mechanical design tool ruler, comprising:

[0031] Tool ruler 1 is a tool that can assist in measurement and drawing and is often used in floor plan design.

[0032] The sliding groove 10 is provided at the end of the tool ruler 1 away from the measuring end, and a sliding block 9 is slidably installed in the inner cavity of the sliding groove 10. The sliding groove 10 and the sliding block 9 are both arranged as a T-shaped structure. The sliding groove 10 can not only limit the sliding trajectory of the sliding block 9, but also prevent the sliding block 9 from falling from the inside of the sliding groove 10 during movement, thereby improving the sliding stability of the sliding block 9.

[0033] When the tool ruler 1 is drawn, the stacking plate 3 is rotated to move along the vertical axis, and the stacking plate 3 is rotated to move along the vertical axis.

[0034] The tool ruler 2 2 is slidably installed on the end of the stacking plate 3 away from the hinged plate 7, and a positioning piece for positioning the tool ruler 2 2 is provided on the outside of the stacking plate 3. Before the stacking plate 3 and the top of the tool ruler 1 are fitted together, the tool ruler 2 2 is moved by the fixing piece to make one end of it fit together with the end of the stacking plate 3 away from the hinged plate 7. At this time, the distance from the end of the stacking plate 3 close to the hinged plate 7 to the end of the tool ruler 2 2 away from the stacking plate 3 is less than the width of the tool ruler 1. When the stacking plate 3 and one end of the tool ruler 2 2 are fitted together with the top of the tool ruler 1, the tool ruler 2 2 is prevented from blocking the scale lines of the tool ruler 1, which makes it convenient for the draftsman to observe the scale lines of the tool ruler 1, thereby improving the accuracy of the drawing of mechanical parts.

[0035] The positioning part includes a guide block 4, and a plurality of guide grooves 13 are opened on the top of the stacking plate 3. The guide blocks 4 are slidably installed in the inner cavities of the plurality of guide grooves 13. The end of the guide block 4 away from the inner cavity of the guide groove 13 is fixedly connected to the end of the tool ruler 2 2 close to the stacking plate 3. The guide groove 13 is connected to the end of the stacking plate 3 away from the hinged plate 7, so that the end of the guide block 4 connected to the tool ruler 2 2 can be moved out from the inside of the guide groove 13 along with the tool ruler 2 2, thereby increasing the movable distance of the guide block 4.

[0036] The length of the guide groove 13 is greater than the length of the guide block 4. When the end of the guide block 4 connected to the tool ruler 2 2 moves to the inside of the guide groove 13, one end of the tool ruler 2 2 can be fitted with one end of the stacking plate 3, effectively reducing the distance between the end of the tool ruler 2 2 away from the stacking plate 3 and the end of the stacking plate 3 close to the tool ruler 2 2, which is beneficial for the draftsman to observe the scale on the tool ruler 1.

[0037] The guide groove 13 and the guide block 4 are both configured as a T-shaped structure to prevent the guide block 4 from escaping from the inside of the guide groove 13, thereby improving the stability of the connection between the tool ruler 2 and the stacking plate 3.

[0038] The stacking plate 3 is provided with a mounting hole at one end close to the hinged plate 7, which is connected to the inner cavity of one of the guide grooves 13. A threaded column 6 is rotatably installed in the inner cavity of the mounting hole. One of the guide blocks 4 is provided with a threaded hole compatible with the threaded column 6 at the end away from the tool ruler 2 2. When the threaded column 6 rotates, the guide block 4 connected thereto can move in the guide groove 13, thereby applying a pulling force or a pushing force to the tool ruler 2 2, allowing the remaining guide blocks 4 to move accordingly, thereby accurately adjusting the distance between the tool ruler 2 2 and the stacking plate 3 and fixing the moved tool ruler 2 2, so as to facilitate the use and storage of the tool ruler 2 2.

[0039] The positioning pin 11 has one end fixedly connected to the end of the tool ruler 1 close to the tool ruler 2 2, and the end of the tool ruler 2 2 close to the tool ruler 1 is provided with a positioning hole 5 adapted to the positioning pin 11. When the length of the marking line is greater than the length of the tool ruler 1 and less than the length after the tool ruler 1 and the tool ruler 2 are connected, the stacking plate 3 is rotated. After the stacking plate 3 is rotated to the top flush with the top of the tool ruler 1 under the cooperation of the hinge plate 7, the tool ruler 2 2 is moved by the fixing piece until the end of the tool ruler 2 2 away from the stacking plate 3 and the end of the tool ruler 1 away from the hinge plate 7 are on the same horizontal line, the moving After that, the tool ruler 2 is fixed. At this time, the middle of the open end of the positioning hole 5 and the middle of one end of the positioning pin 11 are on the same horizontal line. Then push the stacking plate 3 to make it close to the tool ruler 1 until the positioning pin 11 is completely inserted into the inner cavity of the positioning hole 5. At the same time, the stacking plate 3 and one end of the tool ruler 2 are tightly fitted with one end of the tool ruler 1 at the same time, so that one end of the tool ruler 1 is connected with the tool ruler 2 2 and one end of the stacking plate 3, which is conducive to drawing lines of different lengths and preventing offset when drawing lines, reducing the difficulty of drawing mechanical parts and improving the accuracy of drawing mechanical parts.

[0040] The stacking plate 3 and the tool ruler 2 2 and the tool ruler 1 1 have the same height. When drawing mechanical parts, the bottoms of the stacking plate 3 and the tool ruler 2 2 and the tool ruler 1 1 can all fit tightly against the drawing plane, preventing the ends of the tool ruler 2 2 or the tool ruler 1 1 from lifting up when pressing on the top of the tool ruler 2 2 or the tool ruler 1 1, causing the drawn lines to bend and deviate, thereby improving the stability of mechanical parts when drawn using the tool ruler 2 2 and the tool ruler 1 1.

[0041] The locating pin 11 is made of rubber material. The end of the locating pin 11 away from the tool ruler 1 and the inner wall of the locating hole 5 away from its own open end are both set to a conical structure. When the tip of the locating pin 11 is inserted into the inner cavity of the locating hole 5, the inner wall of the locating hole 5 first fits with the inclined side wall of the locating pin 11. At this time, the outer wall of the locating pin 11 is squeezed and deformed until the locating pin 11 is completely inserted into the inner cavity of the locating hole 5. The outer wall of the locating pin 11 fits tightly with the inner wall of the locating hole 5 and applies pressure to the inner wall of the locating hole 5, which increases the friction between the inner wall of the locating hole 5 and the outer wall of the locating pin 11, thereby improving the tightness of the connection between the tool ruler 1 and the tool ruler 2.

[0042] When the tool ruler 1 is in contact with the top of the tool ruler 1, the free end of the fixing bar 12 is pulled, and the fixing bar 12 is deformed. Then, the direction of the free end of the fixing bar 12 is adjusted until the middle of the open end of the through hole and the middle of one end of the limiting post 8 are in the same horizontal line. Then, the free end of the fixing bar 12 is pressed and moved toward the limiting post 8 until one end of the limiting post 8 is inserted into the through hole and its outer wall is tightly fitted with the inner wall of the through hole. This can achieve the limitation of the stacking plate 3 and the tool ruler 2 2 located at the top of the tool ruler 1, preventing the tool ruler 2 2 and the stacking plate 3 from shaking when using the tool ruler 1 to draw, causing drawing interruption and tool ruler 1 deviation.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
