Description

Technical Field

[0001] This utility model relates to the field of ruler technology, specifically a ruler with a rotating function. Background Technology

[0002] A ruler, also known as a measuring ruler or graduated ruler, is a tool used to draw line segments (especially straight ones) and measure lengths (angles). Rulers usually have graduations for measuring length. Some rulers have special shapes, such as letters or circles, in the middle to facilitate drawing. They are commonly used for measuring and calculating lengths (a protractor is used to measure angles, and it is also a type of ruler).

[0003] Rulers are used extensively in teaching, but it is currently difficult to combine rulers with protractors. When drawing straight lines and angles, it is common practice to first draw a straight line, then measure the angle based on that line, and then draw another straight line based on the measured result. This method is inefficient. Utility Model Content

[0004] The purpose of this invention is to provide a ruler with a rotating function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ruler with a rotating function, comprising:

[0006] Rotary connecting seat, ruler plate, and pivot;

[0007] The rotating connecting seat is a hollow frame with an opening on the right side, and an angle scale is provided on the front wall of the rotating connecting seat;

[0008] The left end of each ruler plate is inserted into the rotating connecting seat from the right opening of the rotating connecting seat. The rotating connecting seat has a shaft hole that matches the rotating shaft, and the left end of the ruler plate has a rotating hole that is rotatably connected to the rotating shaft.

[0009] Preferably, movable friction plates are provided on both the front and rear sides of the outer wall of the ruler plate, and fixed friction plates are provided on both the front and rear sides of the inner wall of the rotating connecting seat, which are in contact with the movable friction plates. The rotating shaft passes through the movable friction plates and the fixed friction plates.

[0010] Preferably, the movable friction plate is bonded to the ruler plate by an adhesive layer, and the fixed friction plate is also bonded to the inner wall of the rotating connecting seat by an adhesive layer.

[0011] Preferably, the left side wall of the rotary connector is connected to a hook.

[0012] Preferably, a support rod is fixedly connected to the side of the hook near the rotating connecting seat, and the right side of the support rod is rotatably connected to the left side wall of the rotating connecting seat.

[0013] Preferably, two ruler plates and two rotating shafts are provided. The left ends of the two ruler plates are both arc-shaped. The surface of the arc-shaped part of the ruler plate is provided with external teeth. The external teeth of the two ruler plates mesh with each other. The center of the rotating hole and the center of the arc-shaped part of the left end of the ruler plate are at the same point.

[0014] Preferably, both rulers are provided with opening and closing grooves.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] When using this solution, you can draw a line using a ruler, then rotate the ruler around the pivot on the rotating connector until the desired angle is reached, and then draw another line. This achieves the function of drawing angles without affecting the ruler's ability to measure lengths. It is convenient to use, provides accurate angle drawing, and is highly efficient.

[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 the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Example 1:

[0024] Please see Figure 1-3 This utility model provides a technical solution: a ruler with a rotating function, comprising: a rotating connecting seat 1, a ruler plate 2, and a rotating shaft 8;

[0025] The rotating connecting seat 1 is a hollow frame with an opening on the right side. An angle scale is provided on the front wall of the rotating connecting seat 1. The left end of the ruler plate 2 is inserted into the rotating connecting seat 1 from the right opening of the rotating connecting seat 1. The rotating connecting seat 1 is provided with a shaft hole 9 that matches the rotating shaft 8. The left end of the ruler plate 2 is provided with a rotating hole 5 that is rotatably connected to the rotating shaft 8.

[0026] Analysis of the above content: The rotating shaft 8 is similar to a bolt. The rotating shaft 8 can pass through the shaft hole 9 on the rotating connecting seat 1 and the end of the rotating shaft 8 is fixed by a nut. In this way, the ruler plate 2 can rotate around the rotating shaft 8. An indicator arrow can be set on the left side of the outer wall of the ruler plate 2. The indicator arrow corresponds to the position of the angle scale of the rotating connecting seat 1, which makes it convenient to calculate the rotation angle of the ruler plate 2.

[0027] When using it, hold the rotating connecting seat 1 with one hand and rotate the ruler 2 with the other hand. After rotating it to the appropriate angle, press down on the ruler 2 with the first hand so that the rotating connecting seat 1 and the ruler 2 cannot rotate. Use the other hand to draw lines based on the ruler 2 with a tool such as chalk.

[0028] Example 2:

[0029] Please see Figure 1-3 Based on Embodiment 1, this utility model provides a technical solution: the front and rear sides of the outer wall of the ruler plate 2 are provided with movable friction plates 4, the front and rear sides of the inner wall of the rotating connecting seat 1 are provided with fixed friction plates 6 that are in contact with the movable friction plates 4, and the rotating shaft 8 passes through the movable friction plates 4 and the fixed friction plates 6.

[0030] Analysis of the above content: Based on the friction between the movable friction plate 4 and the fixed friction plate 6, when the ruler 2 drives the movable friction plate 4 to rotate relative to the fixed friction plate 6, the ruler 2 is not easy to rotate on its own. When drawing lines, the ruler 2 is relatively stable, which makes the line angle more accurate.

[0031] Example 3:

[0032] Please see Figure 1-3 Based on Embodiment 2, this utility model provides a technical solution: the movable friction plate 4 and the ruler plate 2 are bonded together by an adhesive layer 7, and the fixed friction plate 6 and the inner wall of the rotating connecting seat 1 are also bonded together by an adhesive layer 7.

[0033] Analysis of the above content: The connection is relatively convenient through the bonding method using adhesive layer 7.

[0034] Example 4:

[0035] Please see Figure 1-3 This utility model provides a technical solution based on Embodiment 1: a hook 11 is connected to the left side wall of the rotary connecting seat 1. A support rod 12 is fixedly connected to the side of the hook 11 near the rotary connecting seat 1, and the right side of the support rod 12 is rotatably connected to the left side wall of the rotary connecting seat 1.

[0036] Analysis of the above content: The support rod 12 is inserted into the rotating connecting seat 1 and locked by the locking pin and other structures, so that the support rod 12 will not detach from the rotating connecting seat 1 and will not affect the rotation of the support rod 12 (the structure here is similar to some existing clothes racks, where the upper hook of the clothes rack can rotate).

[0037] Example 5:

[0038] Please see Figure 1-3 This utility model provides a technical solution based on Embodiment 1: Two ruler plates 2 and two rotating shafts 8 are provided. The left ends of both ruler plates 2 are arc-shaped, and external teeth 3 are formed on the surface of the arc of each ruler plate 2. The external teeth 3 of the two ruler plates 2 mesh with each other. The center of the rotating hole 5 is at the same point as the center of the arc at the left end of the ruler plate 2. Opening and closing grooves 10 are formed on both ruler plates 2.

[0039] Analysis of the above content: The method here sets up two ruler plates 2, which are opened and closed by the opening and closing groove 10. Since the two ruler plates 2 are engaged by the external teeth 3, the two ruler plates 2 can be opened and closed to the required angle according to the needs of use. After opening and closing, it is not necessary to rotate the ruler plates 2 again.
