Description

Technical Field

[0001] This utility model relates to a ruler, and more particularly to a foldable portable ruler. Background Technology

[0002] A ruler is a common measuring and drawing tool, widely used in daily life, learning, engineering, architecture, and design. Existing rulers typically employ a fixed, integrated design, categorized into types such as straight rulers and set squares based on their intended use. While these fixed rulers are simple in structure and easy to use, they present inconveniences when carried: their length is usually quite long, requiring a bag or box exceeding their length for storage and protection. This design places high demands on portability, especially when traveling or when carrying limited tools, making the fixed ruler's carrying method rather cumbersome. Therefore, designing a ruler that meets both measurement needs and high portability has become an urgent problem to solve. Utility Model Content

[0003] This utility model discloses a foldable portable ruler, comprising: independent modules, ball-head bushings, and movable connectors. The ball-head bushings are embeddedly connected to the independent modules. The ball-head bushings are embedded at both the front and rear ends of the independent modules. Different independent modules can be connected to each other via the movable connectors and ball-head bushings. The independent modules can be arranged in a straight line or folded. This utility model, through the technical solution of connecting different independent modules via movable connectors and ball-head bushings, and allowing the independent modules to be arranged in a straight line or folded, achieves a small size and easy portability after folding, solving the problem of the inconvenience of carrying existing fixed rulers.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A foldable portable ruler includes: an independent module, a ball head bushing, and a movable connector. The ball head bushing is embeddedly connected to the independent module. The ball head bushing is embedded at the front end of the independent module and at the rear end of the independent module. Different independent modules can be connected to each other by the movable connector and the ball head bushing. The independent modules can be arranged in a straight line or folded.

[0006] Furthermore, the independent module has notches at both ends, and ball-head bushings are embedded in the notches.

[0007] Furthermore, the movable connector consists of a connecting rod and rolling balls located at both ends of the connecting rod.

[0008] This invention achieves a small size and easy portability of the ruler after folding by using a movable connector to connect different independent modules with a ball head bushing. The independent modules can be arranged in a straight line or folded. This solves the problem of the inconvenience of carrying existing fixed rulers. Attached Figure Description

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] like Figures 1-6 As shown, this utility model provides a foldable portable ruler, including: an independent module 1, a ball-head bushing 2, and a movable connector 3. The ball-head bushing 2 is embeddedly connected to the independent module 1. The ball-head bushing 2 is embedded at both the front and rear ends of the independent module 1. Different independent modules 1 can be connected to each other via the movable connector 3. The independent modules 1 can be arranged in a straight line or folded, thus meeting different measurement and carrying needs. Notches are provided at both ends of the independent module 1, and the ball-head bushing 2 is embedded in these notches. The movable connector 3 consists of a connecting rod 5 and rolling balls 4 disposed at both ends of the connecting rod 5.

[0022] Example 2: Figure 3 As shown, the foldable portable ruler of this invention can be assembled into a triangle with angles of 30°, 60°, and 90°. The three sides of this triangle are formed by connecting independent modules 6 and 7 of different lengths via the aforementioned movable connector 3. The length of module 7 is approximately 0.464 times the length of module 6. This structure is suitable for drawing commonly used right triangles or performing geometric constructions.

[0023] Example 3: Figure 4 As shown, this invention can also be assembled into an isosceles right triangle with angles of 45°, 45°, and 90°. Each of its three sides is formed by multiple independent modules, module one (6) and module three (8), connected by movable connectors (3). The length of module two (7) is approximately 0.828 times the length of module one (6). This structure is suitable for measuring and drawing isosceles right triangles.

[0024] Example 4: Figure 5 As shown, the independent module 1 of this utility model can be arranged in a straight line through the movable connector 3 to form a ruler, which is suitable for conventional length measurement and straight line drawing.

[0025] Example 5: Figure 6As shown, the independent module 1 of this utility model can be folded and arranged via the movable connector 3 when not in use, greatly reducing the size of the ruler and making it easier to store and carry. The folded portable ruler can be easily put into a small storage bag or pocket, solving the problem of the inconvenience of carrying traditional fixed rulers.

[0026] This utility model, through its unique modular design and flexible movable connection structure, achieves innovative functions that can meet various measurement and drawing needs while also being highly portable. The utility model connects different independent modules 1 through movable connectors 3 and ball head bushings 2. The technical solution that allows the independent modules 1 to be arranged in a straight line or folded together makes the ruler small in size after folding and easy to carry, solving the problem that the existing fixed rulers are inconvenient to carry.

[0027] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
