Description

Technical Field

[0001] This utility model relates to the field of measuring ruler technology, and in particular to a multifunctional measuring ruler with mechanical design. Background Technology

[0002] Mechanical design is the process of conceiving, analyzing, and calculating the working principle, structure, motion mode, force and energy transmission mode, material and shape dimensions of each part, lubrication method, etc. of a machine according to the usage requirements, and then transforming them into specific descriptions as the basis for manufacturing.

[0003] Patent document CN217155209U discloses a multifunctional measuring device for mechanical design, including a first measuring scale and a fixed component for indicating the measurement position. The fixed component includes a sliding groove inside the first measuring scale, a second measuring scale inside the sliding groove, a movable groove inside the second measuring scale, a sliding block inside the movable groove, a mounting through hole inside the sliding block, a pad on one side of the mounting through hole, and a locking rod on one side of the pad. This invention solves the problems of existing measuring scales not being able to indicate different scales, inconvenient adjustment of the measuring length of existing measuring scales, and the potential for errors when using the measuring scale to measure the workpiece multiple times, thus reducing the practicality of the equipment for measuring workpiece data.

[0004] The above solution involves extending the overall length of the measuring ruler by pulling the second measuring ruler out from within the first measuring ruler. However, after the second measuring ruler is pulled out, there will be a gap between it and the first measuring ruler, making it impossible for the second measuring ruler to fit flatly onto the drawing. This can cause the lines to be skewed when subsequent personnel use the measuring ruler to draw lines. Utility Model Content

[0005] This utility model discloses a multifunctional measuring ruler with mechanical design, which aims to solve the technical problem of the inconvenience of adjusting the length of the ruler body in existing measuring rulers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multifunctional measuring ruler with mechanical design includes a first ruler body, a second ruler body rotatably connected to the right end of the first ruler body via a rotating shaft, scale strips on the surfaces of both the first and second ruler bodies, a locking mechanism between the first and second ruler bodies, and a distance measuring mark mechanism on the surfaces of both the first and second ruler bodies.

[0008] The locking mechanism includes a mounting groove at the left end of the second ruler body, a rotating opening at the right end of the second ruler body that extends through the mounting groove, an operating rod rotatably connected to the inner wall of the rotating opening, a threaded rod fixedly connected to one end of the operating rod inside the mounting groove, a plug cylinder threadedly connected to the surface of the threaded rod, and a slot adapted to the plug cylinder at the right end of the first ruler body.

[0009] In a preferred embodiment, the surface of the insert is provided with a guide slider, and the inner wall of the mounting groove is provided with a guide groove for the guide slider to slide.

[0010] By setting a guide slider, the insert can move left and right in a directional manner through the rotation of the threaded rod under the guidance of the guide slider.

[0011] In a preferred embodiment, the ranging marking mechanism includes T-shaped grooves respectively formed on the surfaces of the first ruler and the second ruler, and the T-shaped grooves of the first ruler and the second ruler are interconnected. An installation block is slidably connected inside the T-shaped groove, and a T-shaped rod is fixedly connected to the surface of the installation block. A connecting cylinder is sleeved on the surface of the T-shaped rod, and a push block is fixedly installed at the upper end of the connecting cylinder. A pointer corresponding to the position of the scale bar is provided on the surface of the push block.

[0012] By setting up the push block and pointer, after the drawing measurement is completed, the pointer can be moved to the position point measured on the scale bar by pushing the push block, thus recording the measurement data.

[0013] In a preferred embodiment, a spring is fixedly installed on the inner top wall of the connecting cylinder, the lower end of the spring is fixedly connected to the upper end of the T-shaped rod, and two symmetrical abutments are fixedly installed on the surface of the connecting cylinder.

[0014] By using springs and stop blocks, the position of the push block can be limited and fixed.

[0015] In a preferred embodiment, the upper surface of the abutment is provided with an anti-slip pad layer, and the side of the anti-slip pad layer away from the abutment abuts against the inner wall of the T-shaped groove.

[0016] The anti-slip pad layer can improve the stability of the block after it comes into contact with the T-shaped groove.

[0017] In a preferred embodiment, the scale bar is made of fluorescent paint.

[0018] The fluorescent coating on the scale allows people to clearly use the measuring ruler even in dim environments.

[0019] As can be seen from the above, the multifunctional measuring ruler with mechanical design provided by this utility model has the following technical effects.

[0020] Firstly, rotate the second ruler until it is level with the first ruler. Then, rotate the operating lever to rotate the threaded rod. Under the guidance of the guide slider, the insert can move to the left through the rotation of the threaded rod until the insert is inserted into the slot of the first ruler. With the insert in the limiting position, the first and second rulers can be fixedly spliced ​​together to extend the measuring ruler and avoid the gap between the first and second rulers affecting the normal use of the measuring ruler.

[0021] Secondly, when using this measuring ruler for distance measurement, pressing down the push block causes the connecting cylinder to move downwards. The downward movement of the connecting cylinder causes the stop block to separate from the inner wall of the T-shaped groove. Without the limiting effect of the stop block, pushing the push block causes the pointer to move between the surfaces of the first and second rulers until the pointer moves to the measurement point. This can serve as a marker, preventing staff from having to remeasure due to forgetting the measurement data, thus further improving the practicality of the measuring ruler.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figures 1-5 A multifunctional measuring ruler with mechanical design includes a first ruler body 1, a second ruler body 2 rotatably connected to the right end of the first ruler body 1 via a rotating shaft, scale strips 3 on the surface of both the first ruler body 1 and the second ruler body 2, a locking mechanism between the first ruler body 1 and the second ruler body 2, and a distance measuring mark mechanism on the surface of both the first ruler body 1 and the second ruler body 2.

[0030] The scale bar 3 is made of fluorescent paint. The fluorescent paint scale bar 3 allows people to clearly use the measuring ruler even in dim environments.

[0031] The locking mechanism includes a mounting groove at the left end of the second ruler 2, a rotating opening at the right end of the second ruler 2 that extends through the mounting groove, an operating rod 4 that is rotatably connected to the inner wall of the rotating opening, a threaded rod 5 that is fixedly connected to one end of the operating rod 4 inside the mounting groove, a plug 6 that is threaded onto the surface of the threaded rod 5, and a slot 7 that is adapted to the plug 6 that is opened at the right end of the first ruler 1.

[0032] The surface of the insert 6 is provided with a guide slider 8, and the inner wall of the mounting groove is provided with a guide groove for the guide slider 8 to slide. Under the guidance of the guide slider 8, the insert 6 can move left and right in a directional manner by rotating the threaded rod 5.

[0033] Reference Figure 2 , Figure 4 and Figure 5 In a preferred embodiment, the ranging marking mechanism includes T-shaped grooves respectively formed on the surfaces of the first ruler 1 and the second ruler 2, and the T-shaped grooves of the first ruler 1 and the second ruler 2 are interconnected. An installation block 9 is slidably connected inside the T-shaped groove, and a T-shaped rod 10 is fixedly connected to the surface of the installation block 9. A connecting cylinder 11 is sleeved on the surface of the T-shaped rod 10, and a push block 12 is fixedly installed at the upper end of the connecting cylinder 11. A pointer 13 corresponding to the position of the scale bar 3 is provided on the surface of the push block 12.

[0034] By setting up the push block 12 and the pointer 13, after the drawing measurement is completed, the push block 12 can be pushed to point the pointer 13 to the position measured by the scale bar 3, thus recording the measurement data.

[0035] A spring 14 is fixedly installed on the inner top wall of the connecting cylinder 11. The lower end of the spring 14 is fixedly connected to the upper end of the T-shaped rod 10. Two symmetrical abutments 15 are fixedly installed on the surface of the connecting cylinder 11. By setting the spring 14 and the abutments 15, the position of the push block 12 can be limited and fixed.

[0036] The upper surface of the abutment 15 is provided with an anti-slip pad 16, and the side of the anti-slip pad 16 away from the abutment 15 abuts against the inner wall of the T-shaped groove. By providing the anti-slip pad 16, the stability of the abutment 15 after it abuts against the T-shaped groove can be improved.

[0037] Working principle: When the lines on the drawing are too large and the measuring length of the measuring ruler needs to be extended, rotate the second ruler body 2 until it is spliced ​​with the first ruler body 1 at the same level. At this time, rotate the operating lever 4 to drive the threaded rod 5 to rotate. Under the guidance of the guide slider 8, the insert 6 can move to the left through the rotation of the threaded rod 5 until the insert 6 is inserted into the slot 7 of the first ruler body 1. Under the limit of the insert 6, the first ruler body 1 and the second ruler body 2 can be fixedly spliced ​​together to achieve the effect of extending the measuring ruler. When using the measuring ruler for distance measurement, press down the push block 12 to drive the connecting cylinder 11 to move down. The downward movement of the connecting cylinder 11 causes the abutment block 15 to separate from the inner wall of the T-shaped groove. Without the limiting effect of the abutment block 15, push the push block 12 to drive the pointer 13 to move on the surface of the first ruler body 1 and the second ruler body 2 until the pointer 13 moves to the measured point, which can serve as a mark to avoid the staff having to re-measure due to forgetting the measurement data.
