Description

Technical Field

[0001] This utility model relates to the field of stationery technology, and more specifically, to an anti-slip ruler. Background Technology

[0002] Rulers, as basic drawing tools, are widely used in education and design. Traditional rigid plastic rulers have high rigidity and dimensional stability, meeting the needs of accurate drawing. However, their sharp edges pose safety hazards when used by children, especially in case of accidental collisions or falls, which could injure their eyes or skin. To improve safety, rulers made entirely of silicone have appeared on the market. Their softness effectively avoids injuries from sharp edges. However, the inherent limitations of silicone result in insufficient rigidity, making the ruler prone to deformation and compromising the accuracy of straight lines and angular stability during drawing. Summary of the Invention

[0003] This utility model aims to solve one of the technical problems in related technologies to a certain extent. To this end, this utility model proposes an anti-slip ruler, which, by embedding an elastomer at the sharp corner, maintains the rigidity and precision of the rigid body, effectively buffers external impacts, reduces the risk of injury, and ensures the accuracy of the ruler's straight lines and angles.

[0004] The technical solution adopted by this utility model is: to provide an anti-slip ruler, comprising:

[0005] The body is made of rigid material, and the body has a notch at the sharp corner of the anti-slip ruler;

[0006] An elastomer, the tip of which is disposed within the notch and forms the sharp corner of the anti-slip ruler.

[0007] By adopting the above structure, the anti-slip ruler maintains the overall rigidity and dimensional accuracy of its body while effectively buffering external impacts by embedding elastomers at the sharp corners, significantly reducing the risk of injury to the human body from sharp corners. The elastomer material is soft and can deform to a certain extent when compressed, absorbing collision energy and playing a protective role, while the main body of the ruler still maintains the advantages of traditional rigid materials, ensuring that the ruler remains straight and not easily bent during use, and can accurately draw straight lines and angles.

[0008] According to one embodiment of the present invention, the body has a hollowed-out inner ring structure, and the inner sleeve of the elastic body covers the sidewall of the inner ring; or

[0009] The inner sleeve of the elastic body is embedded in the middle of the main body. The inner sleeve is located in the middle of the main body, which not only effectively enhances the anti-slip performance of the ruler, but also improves the comfort of holding and the stability of operation to a certain extent. Under normal circumstances, the main body of the ruler is made of transparent material, while the inner sleeve is made of opaque material. The two are combined in an alternating manner, which not only ensures the functionality, but also further enhances the visual aesthetics and design of the product.

[0010] According to one embodiment of the present invention, the tip of the elastomer is integrally connected to the inner sleeve via a connecting portion; the connecting portion acts as an anchor for the tip, effectively preventing the tip from falling off or deforming excessively when subjected to force.

[0011] According to one embodiment of the present invention, the main body is provided with a connecting groove corresponding to the position of the connecting part, and the connecting part is embedded in the connecting groove to realize the integral connection between the tip of the elastomer and the inner sleeve. This not only further stabilizes the positioning of the elastomer in the main body and prevents displacement or loosening during use, but also improves the tightness and durability of the overall structure.

[0012] According to one embodiment of the present invention, the connecting groove is disposed on one side surface of the body; or

[0013] The connecting groove is disposed through the opposite two sides of the body.

[0014] According to one embodiment of the present invention, the abutting sidewall of the tip cooperates with the notch sidewall to ensure that the tip can effectively abut and be stably fixed during use, and the surface area of ​​the abutting sidewall is greater than the cross-sectional area of ​​the connecting part, thereby increasing the contact area of ​​the connecting part, improving the overall stability, and preventing the tip from being displaced or deformed due to external force.

[0015] According to one embodiment of the present invention, the material of the body is selected from at least one of metal, plastic, or composite material; and / or

[0016] The elastomer is made of soft rubber.

[0017] According to one embodiment of the present invention, the soft adhesive is selected from at least one of silicone, thermoplastic elastomer (TPE), thermoplastic polyurethane (TPU), polyvinyl chloride (PVC), or rubber.

[0018] According to one embodiment of the present invention, the elastomer is combined with the body through a secondary injection molding process.

[0019] According to one embodiment of the present invention, the anti-slip ruler includes a set square, a ruler, a T-shaped ruler, and a protractor. Attached Figure Description

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0035] like Figure 1-8 As shown, this embodiment discloses an anti-slip ruler, comprising:

[0036] A rigid body 1, wherein the body 1 has a notch 12 at the sharp corner of the anti-slip ruler;

[0037] The elastic body 2 has a pointed portion 23 disposed within the notch 12 and forming the pointed corner of the anti-slip ruler.

[0038] Combination Figure 1-7 As shown, in this embodiment, the anti-slip ruler is a set square, specifically a set square with an inclined side. Combined with... Figure 8 As shown, in some other embodiments, the set square is an isosceles right-angled set square. In addition, the anti-slip ruler can also be a ruler with sharp corners, a T-shaped ruler, or a protractor.

[0039] In this embodiment, the body 1 is made of plastic, specifically transparent plastic, while the elastomer 2 is made of silicone. In other embodiments, the elastomer 2 may also be at least one of thermoplastic elastomer 2 (TPE), thermoplastic polyurethane (TPU), polyvinyl chloride (PVC), or rubber, while the body 1 may be at least one of metal or composite material, preferably aluminum alloy, and preferably carbon fiber.

[0040] Combination Figure 1 As shown, in this embodiment, the triangle ruler body 1 is flat, with scales on its two right-angled sides. The body 1 has a hollowed-out triangular inner ring 11 structure, and the inner sleeve 21 of the elastic body 2 covers the side wall of the inner ring 11. Notches 12 are provided at the two acute angles of the body 1, making the outer contour of the body 1 approximately triangular. The tip 23 of the elastic body 2 is integrally connected to the inner sleeve 21 via a connecting part 22, wherein the inner sleeve 21 is combined with the matching triangular inner ring 11 structure, and the tip extends outward and is integrated with the tip 23. The connecting part 22 acts as an anchor, effectively preventing the tip 23 from detaching or excessively deforming under stress. Simultaneously, a connecting groove 13 is provided on one side surface of the body 1, and the connecting part 22 is embedded in the connecting groove 13, ensuring the stability of the structure.

[0041] In some other embodiments, the body 1 has several through holes or grooves in its middle, and the inner sleeve 21 fills these through holes or grooves as anchor points. Subsequently, the inner sleeve 21 is connected to the tip 23 through the connecting part 22, which acts as an anchor rope, further enhancing the stability and reliability of the elastomer 2.

[0042] In some other embodiments, the connecting groove 13 is disposed through the opposite two side surfaces of the body 1, and the connecting part 22 is entirely embedded in the connecting groove 13.

[0043] Specifically, in combination Figure 4 As shown, the abutting sidewall 23a of the tip 23 cooperates with the sidewall of the notch 12 to ensure that the tip 23 can effectively abut and be stably fixed during use. The surface area of ​​the abutting sidewall 23a is larger than the cross-sectional area of ​​the connecting part 22, thereby increasing the contact area of ​​the connecting part 22, improving the overall stability, and preventing the tip 23 from being displaced or deformed due to external force.

[0044] Furthermore, the elastomer 2 is bonded to the body 1 through a secondary injection molding process. Specifically, firstly, the plastic raw material is molded in a primary plastic mold to obtain a rigid plastic body 1 part. This body 1 part is then removed from the mold and placed into a secondary molding mold. Silicone is injected to directly mold the elastomer 2 onto the surface of the body 1. The bottom surface of the elastomer 2 is flush with the bottom surface of the body 1, or the bottom surface of the elastomer 2 is slightly raised above the bottom surface of the body 1. This design ensures that when using the ruler, the bottom surface of the elastomer 2 contacts the tabletop or paper surface. Because the coefficient of friction of soft rubber is higher than that of hard rubber, the elastomer 2 effectively provides anti-slip properties, improving stability during use.
