DETAILED DESCRIPTION

[0033] The present application is further described in detail below with reference to the accompanying drawings.

[0034] The embodiment of the present application discloses a folding measuring ruler. Figure 1 、 Figure 2 and Figure 3 As shown, a folding measuring ruler includes a ruler plate group 1, which includes a main ruler plate 11 and a sub-rule plate 12. One end of the main ruler plate 11 is connected to one end of the sub-rule plate 12, and the main ruler plate 11 and the sub-rule plate 12 are rotatably connected. The other ends of the main ruler plate 11 and the sub-rule plate 12 are both equipped with a flip plate 2. One end of the flip plate 2 is rotatably connected to both the main ruler plate 11 and the sub-rule plate 12, and the other end of the flip plate 2 is rotatably equipped with a connector 3. An angle ruler rod 4 is also installed on the connector 3, and the angle ruler rod 4 is rotatably connected to the connector 3. The ruler plate group 1 is provided as the central component of the entire measuring ruler, and the ruler plate group 1 is designed to be a main ruler plate 11 and a sub-rule plate 12 that can be flipped horizontally. Then, a flip plate 2 is installed on the main ruler plate 11 and the sub-rule plate 12 to extend the length. When not in use, the main ruler plate 11 and the sub-rule plate 12 can be rotated and merged together, and when measurement is needed, they can be flipped to the same straight line for use. The setting of the flip plate 2 makes it convenient to install the angle ruler rod 4 on the main ruler plate 11 and the sub-rule plate 12 respectively, so that the angle ruler rod 4 can be used to further extend the use of the measuring ruler. When the flip plate 2 is installed on the main scale plate 11 or the auxiliary scale plate 12, it can be flipped up for measurement or folded for storage as needed. When the flip plate 2 is flipped up and the length is not enough for use, the angle ruler rod 4 can also be unfolded, so that one side can be folded 4 times, and the two sides can be folded 8 times as a whole. By combining multiple folding and rotating structures, the expansion performance of the folding ruler is greatly enhanced. When installing the angle ruler rod 4, the connecting part 3 needs to be installed on the flip plate 2 to ensure that the angle ruler rod 4 is better flipped for measurement and folded for storage during use.

[0035] Reference Figure 3 、 Figure 4 and Figure 5 As shown, the main scale plate 11 includes a first scale plate 111, a transverse double earring 112, and a first connecting shaft 113. The transverse double earring 112 and the first connecting shaft 113 are respectively provided at the two ends of the first scale plate 111, and the first scale plate 111, the transverse double earring 112, and the first connecting shaft 113 are fixedly connected. By designing the main scale plate 111 with the first scale plate 111, the transverse double earring 112, and the first connecting shaft 113 as a coordinated structure, the first scale plate 111 can be connected to the auxiliary scale plate 12 via the transverse double earring 112 at one end for ease of use, while the flip plate 2 can be attached via the first connecting shaft 113 at the other end. For convenient use, the auxiliary scale plate 12 can be flipped and unfolded horizontally, while the flip plate 2 can be flipped and unfolded vertically for use.

[0036] Reference Figure 7 As shown, the auxiliary scale plate 12 includes a second scale plate 121, a center column 122, and a second connecting shaft 123. The center column 122 and the second connecting shaft 123 are respectively located at the ends of the second scale plate 121 and are fixedly connected to each other. By designing the auxiliary scale plate 12 with the second scale plate 121, the center column 122, and the second connecting shaft 123, the second scale plate 121 can be easily connected to the horizontal double earrings 112 on the first scale plate 111 through the center column 122 at one end, facilitating a stable horizontal rotation connection between the two. Simultaneously, the second connecting shaft 123 is installed at the other end of the second scale plate 121 to mount the flip plate 2, allowing the flip plate 2 to be flipped and unfolded for convenient use. The upper end surface of the first connecting shaft 113 is evenly distributed with angle scales 114 along the circumference, and the upper end surface of the second connecting shaft 123 is provided with an angle pointer 124 corresponding to the angle scale 114. By setting a circle of angle scales 114 at the upper end of the first connecting shaft 113, it is ensured that the angle pointer 124 at the upper end of the second connecting shaft 123 can correspond thereto, so that angle measurement can be achieved through the angle between the main scale plate 11 and the secondary scale plate 12 during use.

[0037] Reference Figure 6 and Figure 7 As shown, one end of the flip plate 2 is provided with a mating sleeve 21 corresponding to the first connecting shaft 113 or the second connecting shaft 123, and the other end of the flip plate 2 is provided with a first positioning clip groove 22 for mounting the connector 3. By providing the mating sleeve 21 on one end of the flip plate 2, it can be mounted on the first connecting shaft 113 or the second connecting shaft 123 during installation, ensuring rotational connection with the main scale plate 11 or the auxiliary scale plate 12, allowing for stable flipping and unfolding during measurement. At the same time, the first positioning clip groove 22 is provided at the other end of the flip plate 2, making it easier to position and install the connector 3. A first plug-in shaft 221 is mounted in the first positioning clip groove 22. The first plug-in shaft 221 is fixedly connected to the flip plate 2 at both ends. The connector 3 is provided with a socket 31 corresponding to the first plug-in shaft 221. By installing the first plug-in shaft 221 in the first positioning clamp groove 22, when the connecting member 3 is positioned and installed in the first positioning clamp groove 22, the first plug-in shaft 221 can be used for limit locking, ensuring that the connecting member 3 can be sleeved on the first plug-in shaft 221 through the socket 31, and can be rotated around the first plug-in shaft 221 when in use.

[0038] Reference Figure 2 and Figure 8As shown, the angle ruler rod 4 includes a bottom plate 41 and a top plate 42. The top plate 42 is mounted at the top of the bottom plate 41 and is rotatably connected to the bottom plate 41. By designing the angle ruler rod 4 with the bottom plate 41 and the top plate 42 cooperating, the bottom plate 41 and the top plate 42 can be folded together when not in use, and can be unfolded for use when measurement is required. The lower end of the bottom plate 41 is provided with a second positioning clamping groove 411 for mounting the connector 3. A second plug-in shaft 412 corresponding to the receptacle 31 is mounted in the second positioning clamping groove 411. A second positioning groove 411 for installing the connecting member 3 is opened at the lower end of the bottom ruler plate 41, and a second plug-in shaft 412 is installed in the second positioning groove 411. When the connecting member 3 is connected, the first plug-in shaft 221 and the second plug-in shaft 412 are respectively inserted into the two sockets 31 of the connecting member 3. In this way, the angle ruler rod 4 can be stably connected to the flip plate 2 through the connecting member 3, and it is also convenient to fold and store when not in use.

[0039] The implementation principle of a foldable measuring ruler in an embodiment of the present application is as follows: during actual measurement, the main scale plate 11 and the auxiliary scale plate 12 on the scale plate group 1 are first flipped and unfolded. After the main scale plate 11 and the auxiliary scale plate 12 are flipped to the same straight line, the measuring ruler can be used twice. When the length is not enough for measurement, the flip plate 2 on the main scale plate 11 and the auxiliary scale plate 12 can be flipped up. After the flip plate 2 is flipped to the same straight line, the measuring ruler can be used four times. When the length is still not enough for measurement, the angle ruler rod 4 on the flip plate 2 can be unfolded. Each angle ruler rod 4 can extend twice the measuring length when unfolded, so after all are unfolded, the measuring ruler can be used eight times. When not in use, it can be folded in sequence, which is very convenient to use. In addition, angle measurement can be achieved by rotating the main scale plate 11 and the auxiliary scale plate 12 during use.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
