Description

Technical Field

[0001] This utility model relates to the field of compass technology, specifically a multifunctional integrated compass. Background Technology

[0002] A compass is a tool used to draw circles and arcs on a plane, as well as to perform circular measurements and positioning. It usually consists of two extendable legs, one with a pointed tip as the center and the other with a pencil or pen tip for drawing arcs. By adjusting the distance between the two legs, circles of different radii can be drawn.

[0003] The compass with patent publication number CN 222451787 U has a first compass leg that rotates relative to the main body shell. The opening degree of the first compass leg relative to the second compass leg matches the scale corresponding to the position where the liquid stops in the liquid flow channel, thus enabling this compass to have other functions. Compared with traditional compasses, this compass is more versatile. The scale is a distance scale, in which case this compass also has the function of measuring length. It can also draw circles of desired size without a ruler. The scale is an angle scale, in which case this compass also has the function of measuring angles.

[0004] When using the above and similar technical solutions, since the learning process may involve the use of compasses, it may be necessary to erase and modify the drawn content, or to draw straight lines, etc. At this time, it is necessary to use other tools, but the compass itself has insufficient functionality, resulting in certain limitations in the use process. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional integrated compass to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional integrated compass, comprising a main body assembly, wherein the main body assembly is provided with a pin assembly and a drawing assembly for drawing straight lines. The main body assembly includes a main rod, on which a first support leg and a second support leg are provided. A first connecting pen is inserted into the first support leg, and the first support leg and the second support leg are hinged together. The drawing assembly includes a drawing pen, which is disposed on the second support leg. The second support leg has a scale groove. The hinged first support leg and the second support leg are separated. The pin assembly limits the second support leg. Circular drawing is performed by retracting the first connecting pen. When the second support leg is laid flat, straight lines are drawn by the scale groove and the drawing pen.

[0007] Furthermore, the pin assembly includes a fixed pin, which is disposed on the second support leg. The fixed pin is a steel structure. A limiting plate is disposed on the second support leg. The limiting plate is connected to the second support leg by threads. Rotating the limiting plate compresses the fixed pin, thereby adjusting the length of the fixed pin.

[0008] Furthermore, the pin assembly includes an adsorption plate made of rubber. Adjusting the length of the fixed pin causes it to retract, and the adsorption plate provides support, offering flexible support.

[0009] Furthermore, the main rod is equipped with a plug rod, and an eraser is sleeved on the plug rod. Drawings can be made, erased, and modified by wiping with the eraser. The eraser sleeved on the plug rod is easy to disassemble and replace quickly.

[0010] Furthermore, the second support leg has a movable groove, in which a limit rod is installed. A sliding block is sleeved on the limit rod. The drawing pen is slidably inserted into the sliding block. Pressing the drawing pen causes it to contact the object to be drawn, and a straight line is drawn according to the markings on the scale groove.

[0011] Furthermore, the drawing pen is equipped with an indicator plate that contacts the second support leg, and the reading of the scale groove is obtained through the position of the indicator plate.

[0012] Furthermore, the second support leg is provided with a cover plate, which has an arc structure. The arc-shaped cover plate, together with the first support leg and the first connecting pen, forms an integral cylinder, making it easy for the user to hold.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This multifunctional integrated compass uses a rotating limiting plate to compress the fixed pins, thereby adjusting their length. The fixed pins provide rigid support, while adjusting their length causes them to retract, providing flexible support via an adsorption plate. Since the first connecting pen and the first support leg are plug-in connected, the length of the first support leg can be extended or retracted. Circular drawing is performed using the retracted first connecting pen, while the second support leg is laid flat, pressing the drawing pen to contact the object being drawn. The reading of the scale groove is obtained through the indicator plate, and straight lines are drawn according to the markings on the scale groove. The drawing is erased and modified using an eraser, which is attached to the plug rod for quick disassembly and replacement, thus achieving a multifunctional integrated effect.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In learning and practice, the compass, as an important drawing tool, is widely used in mathematics, engineering, design, and other fields. However, although the compass performs excellently in drawing circles and arcs, it has certain limitations in functionality, which to some extent affects its efficiency and convenience in practical applications. First, the compass's function is relatively simple; its main function is to draw circles and arcs, controlling the radius of the circle by adjusting the distance between its two legs. However, in actual operation, we often need to erase and modify the drawn content, or perform other operations such as drawing straight lines or measuring angles. In these cases, the compass's functionality is insufficient to meet these needs, requiring the use of other tools such as erasers, rulers, and protractors. The frequent switching of such tools not only reduces work efficiency but also increases the complexity of operation. The multifunctional integrated compass provided in this application draws circles by retracting the first connecting pen, while the second support leg is laid flat and the drawing pen is pressed to make the drawing pen contact the object to be drawn. The reading of the scale groove is obtained through the position of the indicator plate, and straight lines are drawn according to the markings of the scale groove. The drawing is erased and modified by the eraser, which is attached to the plug rod for easy disassembly and replacement.

[0023] like Figures 1-5 As shown, this utility model provides a technical solution: a multifunctional integrated compass, including a main body component 1, a pin assembly 2 and a drawing assembly 3 for drawing straight lines. The main body component 1 includes a main rod 101, a first support leg 104 and a second support leg 107 are provided on the main rod 101, a first connecting pen 105 is inserted into the first support leg 104, and the first support leg 104 and the second support leg 107 are hinged. The drawing assembly 3 includes a drawing pen 303, which is disposed on the second support leg 107, and the second support leg 107 has a scale groove 108.

[0024] It should be noted that during use, the hinged first support leg 104 and the second support leg 107 are separated, and the second support leg 107 is limited by the pin assembly 2. Since the first docking pen 105 and the first support leg 104 are connected by a plug-in connection, the length of the first support leg 104 can be reduced and extended. At this time, a circle is drawn by the reduced first docking pen 105, while the second support leg 107 is laid flat and a straight line is drawn by the scale groove 108 and the drawing pen 303.

[0025] like Figure 5 As shown, the pin assembly 2 includes a fixing pin 201, which is disposed on the second support leg 107. The fixing pin 201 is a steel structure. A limiting plate 202 is disposed on the second support leg 107, and the limiting plate 202 is connected to the second support leg 107 by threads.

[0026] It should be noted that rotating the limiting plate 202 will compress the fixing pin 201, thereby adjusting the length of the fixing pin 201.

[0027] like Figure 5 As shown, the pin assembly 2 includes an adsorption plate 203, which is made of rubber.

[0028] It should be noted that adjusting the length of the fixing pin 201 causes the fixing pin 201 to retract, and it is supported by the suction cup 203 to provide flexible support.

[0029] like Figure 3 As shown, a plug rod 102 is provided on the main rod 101, and a wiping eraser 103 is sleeved on the plug rod 102.

[0030] It should be noted that the eraser 103 is used for drawing, erasing and modification. The eraser 103, which is attached to the plug rod 102, is easy to disassemble and replace quickly.

[0031] like Figure 4As shown, the second support leg 107 has a movable groove 301, a limit rod 302 is provided in the movable groove 301, a sliding block is sleeved on the limit rod 302, and the drawing pen 303 is slidably inserted into the sliding block.

[0032] It should be noted that pressing the drawing pen 303 causes the drawing pen 303 to come into contact with the object to be drawn, and straight lines are drawn according to the markings on the scale groove 108.

[0033] like Figure 4 As shown, the drawing pen 303 is equipped with an indicator plate 304, which is in contact with the second support leg 107.

[0034] It should be noted that the reading of the scale groove 108 is obtained through the position of the indicator plate 304.

[0035] like Figure 2 As shown, a cover plate 106 is provided on the second support leg 107, and the cover plate 106 has an arc structure.

[0036] It should be noted that the arc-shaped cover plate 106, the first support leg 104, and the first docking pen 105 form an integral cylinder, which is convenient for the user to hold.

[0037] It should be noted that during use, the hinged first support leg 104 and second support leg 107 are separated. The arc-shaped cover plate 106, the first support leg 104, and the first connecting pen 105 form a single cylinder, making it easy for the user to hold. Rotating the limiting plate 202 compresses the fixing pin 201, thereby adjusting the length of the fixing pin 201. The fixing pin 201 provides rigid support, and adjusting its length causes it to retract, providing flexible support through the suction plate 203. The first connecting pen 105... The first support leg 104 is plugged in, so the length of the first support leg 104 can be retracted and extended. At this time, the first support leg 107 is retracted to draw a circle with the pen 105. The second support leg 107 is laid flat and the drawing pen 303 is pressed, so that the drawing pen 303 comes into contact with the object to be drawn. The reading of the scale groove 108 is obtained through the position of the indicator plate 304. A straight line is drawn according to the mark of the scale groove 108. The drawing is erased and modified by the eraser 103. The eraser 103, which is sleeved on the plug rod 102, is easy to disassemble and replace quickly.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
