Description

Technical Field

[0001] This utility model relates to the field of stationery, and in particular to a multifunctional ruler with anti-slip positioning. Background Technology

[0002] A multi-functional ruler is a tool that integrates multiple measurement and drawing functions. It typically possesses the basic measurement functions of a ruler while incorporating features of a protractor and compass to meet user needs in various scenarios. These rulers utilize innovative structural design to integrate multiple functions into one unit, aiming to improve efficiency and reduce the number of tools required. However, traditional multi-functional rulers often have design limitations, particularly in terms of anti-slip performance and dynamic drawing capabilities, making it difficult to meet the demands of high-precision or complex drawing scenarios.

[0003] Traditional multi-functional rulers typically only have an anti-slip structure in a single location. When drawing lines, measuring, or drafting, the ruler is prone to slipping or shifting due to uneven force, leading to decreased drafting accuracy. Furthermore, while some rulers have a circle-drawing function, this requires additional accessories or fixing devices, making the operation cumbersome and limiting the flexibility of use as the radius cannot be adjusted in real time. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing multi-functional rulers in terms of anti-slip performance and dynamic drawing function, and to propose a multi-functional ruler with anti-slip positioning.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution: A multifunctional ruler with anti-slip positioning includes a rectangular ruler. One end of the rectangular ruler has a circular groove, and a circular rod is vertically slidably connected in the circular groove. A cross-shaped movable groove is opened on the rectangular ruler, and a movable block is slidably connected in the movable groove. A slot for inserting a pen is provided through the center of the movable block. Anti-slip components are provided at the lower ends of the circular rod and the movable block.

[0006] Preferably, the anti-slip component includes a rubber pad and a rubber ring, wherein the rubber pad is fixedly connected to the lower end of the round rod, and the rubber ring is fixedly connected to the lower surface of the moving block.

[0007] Preferably, the movable block is threaded with a screw on its side, and a rotating ring is fixedly provided at one end of the screw that passes through the movable groove. A frustum-shaped rubber sleeve is fixedly provided at the center of the rotating ring, and the rubber sleeve is fitted onto the end of the screw.

[0008] Preferably, the upper end of the round rod is provided with a ring, the lower surface edge of the ring is provided with two locking rods symmetrically, and the upper surface of the rectangular ruler is provided with two locking blocks symmetrical to the locking rods.

[0009] Preferably, a positioning ring is fixedly provided on the upper surface of the moving block, and a pointer is engaged between the positioning ring and the moving block.

[0010] Preferably, the measuring end of the rectangular ruler has an inclined surface, and the inclined surface has scale lines.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, by adopting a double-point anti-slip structure, anti-slip components are simultaneously set at the end of the ruler and below the moving parts to form a multi-point support effect, which effectively enhances the friction between the tool and the drawing surface. Even under different angles or forces, it can still maintain stable positioning, greatly reducing the risk of displacement and ensuring the accuracy of lines or measurements. 2. In this utility model, the sliding block design within the cross-shaped moving groove overcomes the limitations of traditional fixed central holes. By adjusting the position of the moving block within the groove, the user can directly control the distance between the pen and the center of the round rod within the slot, achieving stepless radius adjustment. Rotating the ruler body around the round rod as an axis, the pen, constrained by the moving block, outputs a perfect circle, significantly improving portability and adaptability to various drawing scenarios.

[0014] 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.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] In the description of this specification, the references to terms such as "embodiment," "one embodiment," "some implementations," "exemplary," and "one implementation," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or implementation of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0017] Example: This example provides a multi-functional ruler with anti-slip positioning. See [link / reference]. Figure 1-5 Specifically, it includes a rectangular ruler 1, one end of which is provided with a circular groove 11, and a circular rod 12 is vertically slidably connected in the circular groove 11. A cross-shaped moving groove 13 is provided on the rectangular ruler 1, and a moving block 14 is slidably connected in the moving groove 13. A pen slot 15 is provided through the center of the moving block 14. Anti-slip parts 2 are provided at the lower ends of the circular rod 12 and the moving block 14.

[0018] In this embodiment, the circular groove 11 and the circular rod 12 are connected. The circular rod 12 can slide vertically along the circular groove 11, allowing the rectangular ruler 1 to move upward along the circular rod 12. This allows the lower surface of the rectangular ruler 1 to leave the anti-slip part 2. As the rectangular ruler 1 rises, the anti-slip part 2 on the moving block 14 also leaves the table or paper, facilitating the rotation of the rectangular ruler 1 around the circular rod 12. The moving groove 13 and the moving block 14 are connected. The cross-shaped groove allows the moving block 14 to slide laterally within the groove without detaching from the moving groove 13. The slot 15 is used to insert a drawing pen. Since the volume of some pens differs from the area of ​​the slot 15, the pen cannot be fixed vertically after being inserted into the slot 15. Users need to fill the space between the slot 15 and the pen to keep the pen vertically in the slot 15. Then, by rotating the pen or the rectangular ruler 1, arcs or circles can be drawn. When drawing straight lines, it is only necessary to align the bevel of the rectangular ruler 1 with the pen tip.

[0019] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the anti-slip component 2 includes a rubber pad 21 and a rubber ring 22. The rubber pad 21 is fixedly connected to the lower end of the round rod 12, and the rubber ring 22 is fixedly connected to the lower surface of the moving block 14.

[0020] In this embodiment, when the rubber pad 21 serves as the fulcrum of the round rod 12, the rubber pad 21 contacts the drawing surface, increasing friction and preventing the fulcrum from slipping and causing deviation in the circle drawing. The rubber ring 22 encircles the bottom edge of the moving block 14, increasing multi-directional frictional resistance. When drawing arcs or circles, the rectangular ruler 1 needs to move upward along the round rod 12 first, so that the rubber ring 22 on the lower surface of the moving block 14 is suspended, making it convenient for the rectangular ruler 1 to rotate around the round rod 12. When drawing straight lines, the entire rectangular ruler 1 remains stable through the support of the rubber pad 21 and the rubber ring 22.

[0021] In the specific implementation process, such as Figure 2 and Figure 5 As shown, the movable block 14 has a screw 32 threaded on its side. A rotating ring 3 is fixed at one end of the screw 32 that passes through the movable groove 13. A frustum-shaped rubber sleeve 31 is fixed at the center of the rotating ring 3 and is fitted onto the end of the screw 32.

[0022] In this embodiment, the screw 32 is moved laterally along the moving block 14 by rotating the rotating ring 3. When the rubber sleeve 31 enters the opening of the moving groove 13, the rubber sleeve 31 generates friction with the inner wall of the moving groove 13, fixing the position of the moving block 14, preventing the moving block 14 from being accidentally displaced, and improving the accuracy of arc or circular drawing.

[0023] In the specific implementation process, such as Figure 3 and Figure 4 As shown, a circular ring 4 is rotatably provided at the upper end of the circular rod 12, and two locking rods 41 are symmetrically provided on the lower edge of the circular ring 4. Two locking blocks 42 are provided on the upper surface of the rectangular ruler 1, which are symmetrical to the locking rods 41.

[0024] In this embodiment, when the rectangular ruler 1 is raised, the locking rod 41 is inserted into the groove of the locking block 42 to lock the height of the rectangular ruler 1, making it convenient for the rectangular ruler 1 to rotate along the circular rod 12. The locking block 42 is fixed to the ruler body and provides a locking fulcrum. The locking rod 41 is made of elastic plastic material, and the locking rod 41 can be separated from the locking block 42 by pulling force. When the rectangular ruler 1 rotates, the locking rod 41 and the locking block 42 drive the ring 4 to rotate along the circular rod 12.

[0025] In the specific implementation process, such as Figure 1 and Figure 2 As shown, a positioning ring 5 is fixedly provided on the upper surface of the moving block 14, and a pointer 51 is engaged between the positioning ring 5 and the moving block 14.

[0026] In this embodiment, when the moving block 14 slides along the moving groove 13, the pointer 51 moves with the moving block 14 and points to the scale line on the ruler. The user can quickly determine the current position of the pen by observing the position of the pointer 51, thereby improving the operation accuracy.

[0027] In the specific implementation process, such as Figure 1 As shown, the measuring end of the rectangular ruler 1 is provided with an inclined surface 6, and scale lines are provided on the inclined surface 6; the inclined surface 6 reduces the thickness of the rectangular ruler 1, facilitates the contact between the rectangular ruler 1 and the pen refill, and optimizes the reading angle of the scale to avoid obstruction of the line of sight; thus enabling the drawing of straight lines.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
