Description

Technical Field

[0001] This utility model relates to the field of stationery technology, and in particular to a multifunctional assembly ruler. Background Technology

[0002] Rulers are an indispensable stationery item for students. Every student carries several rulers of different sizes in their schoolbag or pencil case to draw or measure line segments of different lengths.

[0003] One common type of ruler is the rigid ruler, which has graduations on its surface to aid in length measurement. Currently, most rigid rulers on the market only offer length measurement, making their function relatively simple. Furthermore, since the length of a ruler is generally fixed, measuring objects longer than the maximum graduation requires multiple measurements, making it difficult to use a single ruler and resulting in significant errors. Therefore, in many cases, a measuring tape is the preferred alternative. Additionally, existing rulers rarely offer DIY features or are too generic; consequently, rulers are generally only displayed in stationery sections, rarely appearing in creative or cultural product sections. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a multifunctional assembly ruler.

[0005] The technical solution adopted in this utility model is: a multifunctional assembly ruler, comprising:

[0006] At least two unit rulers, each unit ruler having a shaft at at least one end;

[0007] An adapter is installed between the ends of two adjacent unit rulers. The adapter has two spaced-apart adapter slots for the shaft to be rotatably mounted.

[0008] Two adjacent unit rulers have a straight ruler state where they are rotated relative to the adapter to be on the same straight line, and a turning state where they are rotated relative to the adapter to be at an angle to each other.

[0009] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0010] Preferably, the unit ruler is provided with the shaft at both the left and right ends.

[0011] Preferably, the adapter includes a base plate, on which two spaced-apart bearings are provided, and the adapter slot is disposed on the bearings.

[0012] Preferably, the end of the unit ruler is provided with a rotation clearance opening, and the shaft is fixedly disposed inside the rotation clearance opening.

[0013] Preferably, in the straight ruler state, the adapter is located inside the enclosing area formed by the two rotation clearance openings.

[0014] Preferably, the extension direction of the unit ruler is set as a first direction, and the extension direction of the shaft is set as a second direction, wherein the first direction and the second direction are perpendicular to each other.

[0015] Preferably, in the ruler state, the base plate is disposed on the upper side (front) of the assembly ruler, and the bearing seat is disposed on the lower side (back) of the assembly ruler.

[0016] Preferably, in the straight ruler state, the ends of two adjacent unit rulers abut against each other and form a rotation limit.

[0017] Preferably, the outer surface of the unit ruler is provided with several protrusions, which are used to cooperate with the detachable installation of decorative blocks.

[0018] More preferably, a key ring is attached to one of the shafts that is not rotatably mounted in the adapter slot.

[0019] Compared with the prior art, this utility model has the following beneficial effects:

[0020] 1. Provides multiple unit rulers and adapters, and sets a shaft at the end of the unit ruler. When it is necessary to extend the length of the unit ruler, simply rotate the shafts of the two unit rulers into the two adapter slots on the same adapter. The assembly is simple, which makes it easier and more accurate to measure the length of longer objects.

[0021] 2. Since both ends of the unit ruler are equipped with shafts, more than two unit rulers can be continuously assembled, and theoretically the length can be increased indefinitely.

[0022] 3. By setting multiple raised points on the front of the unit ruler, users can freely DIY decorative blocks of different elements, similar to Lego brick assembly, making it more fun;

[0023] 4. The shaft at the end of the unit ruler can be connected with a key ring to form a key ring pendant; or, two adjacent unit rulers can be rotated to form an angle between them and placed upright as a signboard, which is suitable for sale as a cultural and creative product.

[0042] Detailed implementation plan: See below Figures 1-12 This utility model is a multifunctional assembly ruler, comprising:

[0043] At least two unit rulers 1, and at least one end of each unit ruler 1 is provided with a shaft 12;

[0044] The adapter 2 is installed between the ends of two adjacent unit rulers 1. The adapter 2 is provided with two mutually spaced adapter slots 221, which allow the shaft 12 to be rotatably installed.

[0045] Two adjacent unit rulers 1 have a straight ruler state where they rotate relative to the adapter 2 to be on the same straight line, and a turning state where they rotate relative to the adapter 2 to be at an angle to each other.

[0046] As a preferred embodiment of this example, please refer to Figure 3 As can be seen, the left and right ends of unit ruler 1 are equipped with shafts 12.

[0047] Here, by setting shafts 12 at both ends of unit ruler 1, multiple unit rulers 1 can be assembled sequentially after the ends of adjacent unit rulers 1 are rotatably installed in the adapter slots 221 on the adapter 2 via shafts 12. Users can choose to assemble a specific number of unit rulers 1 according to their needs. For example, when assembling two unit rulers 1, one adapter 2 is required; when assembling three unit rulers 1, two adapters 2 are required.

[0048] Then, please see Figure 4 As can be seen, in this embodiment, the adapter 2 includes a base plate 21, on which two spaced-apart bearing seats 22 are provided, and the adapter slot 221 is provided on the bearing seats 22.

[0049] In addition, in this embodiment, the end of the unit ruler 1 is provided with a rotation clearance opening 11, and the shaft 12 is fixedly installed inside the rotation clearance opening 11.

[0050] Here, by setting a rotation clearance opening 11 at the end of the unit ruler 1, during the rotation of the shaft 12 of the unit ruler 1 around the bearing 22 on the substrate 21, the substrate 21 will pass through the rotation clearance opening 11, so as not to affect the normal rotation of the unit ruler 1.

[0051] And please see Figure 1 and Figure 2 As can be seen, in the straight ruler state, the ends of two adjacent unit rulers 1 abut against each other and form a rotation limit. The adapter 2 is located inside the enclosing area formed by the two rotation clearance ports 11. The base plate 21 is located on the upper side (front) of the assembled ruler, and the bearing seat 22 is located on the lower side (back) of the assembled ruler.

[0052] In the straight ruler state, since the ends of two adjacent unit rulers 1 abut against each other, on the one hand, the scale of adjacent unit rulers 1 can be directly continued with minimal error. For example, if the upper limit of the scale of a single unit ruler 1 is 10cm, the upper limit of the scale becomes 20cm after two unit rulers 1 are joined together. On the other hand, it can increase structural stability. In the straight ruler state, the unit ruler 1 can only rotate downwards and cannot continue to rotate upwards.

[0053] Furthermore, in this embodiment, the substrate 21 is placed on the upper side of the assembly ruler, which does not affect the overall aesthetics of the assembly ruler.

[0054] In practical applications, for ease of measurement, the unit ruler 1 is generally made of transparent plastic, while the adapter 2 can be made of opaque material.

[0055] Please see Figure 6 To save space, the two unit rulers 1 can be folded together so that their lower sides abut against each other. It is also possible to install another adapter 2 on the end of the unit ruler 1 away from the adapter 2, so as to restrict the two unit rulers 1 from rotating relative to each other.

[0056] In another preferred embodiment of this invention, the extension direction of the unit ruler 1 is set as the first direction, and the extension direction of the shaft 12 is set as the second direction, with the first direction and the second direction being perpendicular to each other.

[0057] Please see Figure 4 As can be seen, in this embodiment, the transition slots 221 on the two bearing seats 22 on the same substrate 21 are also parallel to each other. This design is mainly to facilitate the overall extension direction of the assembled ruler after multiple unit rulers 1 are assembled together, and the assembly between unit rulers 1 will also be simpler.

[0058] Then, please see Figure 3 and Figure 5 As can be seen, in this embodiment, the outer surface of the unit ruler 1 is provided with several protrusions 13, which are used to cooperate with the detachable installation of the decorative block 3.

[0059] Regarding the assembly of decorative block 3 and raised dot 13, please refer to the assembly method of LEGO bricks; details will not be elaborated here. Furthermore, in this embodiment, in addition to selecting decorative blocks 3 of different shapes, various auspicious words such as "peace and joy" can be painted on the surface of the decorative blocks 3, or personalized pictures can be painted on them, which will be more appealing to consumers.

[0060] Next, please refer to Figure 7 As you can see, when the two unit rulers 1 are assembled together, the two unit rulers 1 can be rotated relative to the adapter 2 to form an angle between them, and the ends of the two unit rulers 1 away from the adapter 2 can be placed on the table. This way, they can be used as standees, which is very creative. Furthermore, decorative blocks 3 can be added to the surface of the unit rulers 1 for decoration.

[0061] Please see Figure 8 In this embodiment, a key ring 4 can also be connected to the shaft 12 of the unit ruler 1 to form a key ring pendant.

[0062] Of course, in actual use, the assembly ruler in this embodiment can be used not only as a standee and keychain, but also in many other interesting ways. For example, please refer to... Figure 9 and Figure 10 When the three unit rulers 1 are assembled together, the ends of the assembled rulers can be connected again using adapter 2, thus forming a triangular ring; please refer toFigure 11 and Figure 12 When the four unit rulers 1 are assembled together, the ends of the assembled rulers can be connected again using adapter 2, thus forming a rectangular ring.

[0063] In addition, since both ends of the unit ruler 1 are equipped with shafts 12, the unit ruler 1 can be designed as an ornament for display. For example, two supports or small figures can be designed to hold up the shafts 12 located at both ends of the unit ruler 1. The unit ruler 1 can be placed horizontally on the table. Combined with the decorative blocks 3 on the unit ruler 1, it is very interesting and artistic.

[0064] The above description of a multifunctional assembly ruler is only a preferred embodiment of this utility model and does not limit the patent scope of this utility model. All equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
