Description

Technical Field

[0001] The utility model relates to the technical field of electronic digital display rulers, in particular to a portable electronic digital display ruler. Background Technique

[0002] In the current measuring tool market, as a measuring device that combines the measurement accuracy of traditional rulers with the convenience of modern electronic technology, electronic digital display rulers have been widely used in many fields such as machining, precision manufacturing, and quality inspection. Through the built-in sensors and displays, such tools can display the size of the measured object in real time and accurately, greatly improving the measurement efficiency and accuracy.

[0003] However, despite the significant advantages in function, the limitations in design of electronic digital display rulers are gradually emerging. Specifically, most of the current electronic digital display rulers on the market adopt a straight ruler or fixed-length design and cannot be folded or telescoped, which to a certain extent limits their portability. For measurement personnel who need to move frequently or switch between different working scenarios, carrying such a large-sized and non-foldable electronic digital display ruler undoubtedly increases the burden and inconvenience. Content of the Utility Model

[0004] (I) Purpose of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide a portable electronic digital display ruler to solve the problems raised in the above background.

[0006] (II) Technical Solution

[0007] A portable electronic digital display ruler includes a first ruler body. A data display is arranged on the outer surface of the first ruler body. A cavity is opened at one end of the first ruler body, and a movable plate is movably installed in the cavity. One end of the movable plate is connected with a connecting piece, and shaft rods are installed on the inner walls at both ends of the connecting piece. Connecting plates are movably installed on the outer surfaces of the shaft rods. One end of a connecting plate is connected with the movable plate, and one end of the other group of connecting plates is connected with a first connecting plate, and one end of the first connecting plate is connected with a second ruler body.

[0008] Preferably, limiting grooves are opened on both the upper and lower sides of the inner wall cavity of the first ruler body, and limiting blocks are movably installed on the inner walls of the limiting grooves. The limiting grooves and limiting blocks can ensure that the movable plate maintains the correct trajectory and position during the sliding process.

[0009] Preferably, an installation groove is opened at the top end of the limiting block, and multiple rotating rollers are movably installed in the installation groove. The rotating rollers can effectively reduce friction and improve the smoothness of operation and service life.

[0010] Preferably, a plurality of sets of magnetic rods are fixedly mounted on an outer surface of one side of the first ruler, and magnetic force is used to realize rapid connection and separation between the first ruler and the second ruler.

[0011] Preferably, a plurality of magnetic grooves are provided on an outer surface of one side of the second ruler body. The design of the magnetic grooves enables the magnetic rods on the first ruler body to be more stably embedded therein, forming a more secure connection, thereby facilitating people's use.

[0012] Preferably, a limit plate is fixedly mounted on one end of the second ruler, and the limit plate serves to limit the sliding movement of the data display, thereby preventing the data display from being separated from the outer surface of the ruler.

[0013] Preferably, one end of the magnetic rod is in an arc shape, and the arc-shaped design enables the magnetic rod to slide in more smoothly when docking with the magnetic groove on the second ruler body, thereby reducing the resistance caused by right angles or sharp edges.

[0014] It can be seen from the above technical solutions that the present application has the following beneficial effects:

[0015] 1. The utility model uses the shaft to rotate the connecting plate, so that the second ruler and the first ruler can be folded tightly together, reducing the overall volume and making it easier to carry and store. This design is particularly suitable for surveyors who need to move frequently or switch between different work scenes.

[0016] 2. The utility model facilitates the stable connection between the first scale body and the second scale body through magnetic connection, so that the scale card as a whole can maintain straightness and stability during measurement, thereby improving the accuracy and reliability of measurement. The arc-shaped design at one end of the magnetic rod is not only beautiful, but also plays an important role in actual operation. It can reduce the resistance during connection and separation, making the operation smoother and more fluent, and avoiding the problem of jamming or damage caused by sharp corners.

[0017] 3. The utility model ensures that the movable plate can strictly follow the predetermined track and position during the sliding process by opening limit grooves on the upper and lower sides of the inner wall cavity of the first ruler body and installing limit blocks. This precise guiding mechanism effectively prevents the movable plate from deflecting or shaking, thereby improving the overall structural stability and measurement accuracy of the ruler card, and the multiple sets of rotating rollers movably installed in the installation groove at the top of the limit block are the key to reducing friction and improving the smoothness of operation. When the movable plate slides in the limit groove, the rotating roller can roll instead of sliding, which greatly reduces the friction resistance and makes the operation easier and smoother.

[0026] Please refer to Figures 1-6 , an embodiment provided by the present utility model:

[0027] A portable electronic digital display ruler card, including a first ruler body 2, a data display 1 is arranged on the outer surface of the first ruler body 2, a cavity is opened at one end of the first ruler body 2, and a movable plate 6 is movably installed in the cavity. One end of the movable plate 6 is connected to a connecting piece 8, and shaft rods 9 are installed on the inner walls at both ends of the connecting piece 8. Connecting plates 7 are movably installed on the outer surfaces of the shaft rods 9. One end of a connecting plate 7 is connected to the movable plate 6, and one end of another group of connecting plates 7 is connected to a first connecting plate 5, and one end of the first connecting plate 5 is connected to a second ruler body 3.

[0028] On both the upper and lower sides of the inner wall cavity of the first ruler body 2, limiting grooves 111 are provided, and limiting blocks 112 are movably installed on the inner walls of the limiting grooves 111. The limiting grooves 111 and the limiting blocks 112 can ensure that the movable plate 6 maintains the correct trajectory and position during the sliding process. An installation groove is provided at the top of the limiting block 112, and multiple groups of rotating rollers 113 are movably installed in the installation groove. The rotating rollers 113 effectively reduce friction and improve the smoothness and service life of the operation.

[0029] On the outer surface of one side of the first ruler body 2, multiple groups of magnetic rods 211 are fixedly installed, and the first ruler body 2 and the second ruler body 3 are quickly connected and separated by using magnetic force. Multiple groups of magnetic grooves 311 are provided on the outer surface of one side of the second ruler body 3. The design of the magnetic grooves 311 enables the magnetic rods 211 on the first ruler body 2 to be more stably embedded therein, forming a more firm connection, thereby facilitating people's use. A limiting plate 4 is fixedly installed at one end of the second ruler body 3. The limiting plate 4 plays a role in slidingly limiting the data display 1 to prevent the data display 1 from detaching from the outer surface of the ruler body. One end of the magnetic rod 211 is arc-shaped. The arc-shaped design enables the magnetic rod 211 to slide more smoothly when docking with the magnetic groove 311 on the second ruler body 3, reducing the resistance generated by right angles or sharp edges.

[0030] Working principle: First, by pulling the second ruler body 3, the movable plate 6 can be detached from the cavity on one side of the second ruler body 3, and this action will overcome the magnetic attraction force between the magnetic rod 211 and the magnetic groove 311, separating the two. The arc-shaped design at one end of the magnetic rod 211 helps to smoothly separate, reducing resistance, so that the movable plate 6 will slide along the cavity inside the first ruler body 2 until it is fully unfolded. At this time, through the supporting action of the shaft rod 9, the connecting plate 7 maintains a stable connection state, allowing the first ruler body 2 and the second ruler body 3 to maintain a certain straightness and stability when unfolded. Through the action of the shaft rod 9, the connecting plate 7 can rotate, enabling the second ruler body 3 and the first ruler body 2 to be folded together, thereby facilitating people to carry.
