Description

Technical Field

[0001] This utility model relates to the field of pencil technology, specifically a measuring pencil with graduated markings. Background Technology

[0002] As the most basic and portable drawing and marking tool, the pencil has advantages such as instant marking, flexibility, and low cost. Pencils are commonly used in many fields such as woodworking, clothing cutting, and architectural sketching, playing a unique role due to their erasable and correctable nature.

[0003] To facilitate rough measurements, existing pencils typically have markings on the outside of the pencil. However, this prevents users from using the same pencil to make drawings while measuring, and relying solely on the markings on the outside of the pencil results in limited measurement functionality. Utility Model Content

[0004] The purpose of this invention is to provide a measuring pencil with graduated markings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a measuring pencil with graduated markings, comprising a pencil shell, a lead cylinder fixedly installed inside the pencil shell, a sliding groove formed inside the pencil shell, a sleeve fitted inside the pencil shell, a slider fixedly connected to the outside of the sleeve, several graduated lines formed on the outside of the sleeve, one end of the sleeve fixedly connected to a connecting plate, a pencil end provided at one end of the lead cylinder, the pencil end including a level, an anti-roll frame fixedly connected to the outside of the pencil shell, a rotating plate provided inside the anti-roll frame, and the rotating plate fixedly connected to one end of a protractor display plate.

[0006] Preferably, the pen shell is transparent, and a fixing groove is formed inside the pen shell. The fixing groove is an annular groove and is connected to a plurality of evenly distributed sliding grooves.

[0007] Preferably, both the sliding groove and the fixing groove are slidably engaged with the outer side of the slider, and the slider and the connecting plate are located at the two ends of the sleeve, respectively.

[0008] Preferably, the connecting plate has several connecting grooves on its side, and the connecting grooves are inserted into the slider.

[0009] Preferably, the two ends of the level are respectively connected and fixed to the end plate, and the side of the end plate is threaded to one end of the pen refill cylinder.

[0010] Preferably, the inner wall of the roll cage is rotatably fitted to both ends of the rotating shaft, the outer side of the rotating shaft is fixedly connected to the rotating plate, both ends of the protractor display plate are fixedly connected to the roll cage and the rotating plate respectively, the protractor display plate is a transparent semi-circle, and the center of the protractor display plate is fixedly connected to the reinforcing rib.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses scale lines on the outside of the sleeve for measurement in conjunction with a transparent pen shell. The slider can be moved in the fixed groove by rotating the connecting plate, and then the slider enters the groove until the sleeve is detached from the pen shell. Measurement can then be performed through the sleeve and marked with a pencil, improving the flexibility of pencil measurement. The slider can also be placed in the connecting groove to connect the two sleeves, thus compensating for the insufficient measurement scale of the sleeve.

[0013] 2. This utility model also features a level on the side of the end plate. By rotating the end plate, the level can be removed from the outside of the pencil lead cylinder and used for level testing. The end plate is made of magnetic metal to prevent the level from rolling during measurement and affecting its use. By rotating the rotating plate, the protractor plate inside the anti-roll frame can be unfolded, and the protractor can be used to perform rough angle measurement, thus realizing the multi-functional measurement of pencils.

[0020] 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.

[0021] Please see Figure 1-5This utility model provides a technical solution: a measuring pencil with graduation marks, including a pencil shell 1, a lead cylinder 2 fixedly installed inside the pencil shell 1, a pencil lead inside the lead cylinder 2, a section of the pencil lead extending to the outside of the pencil tip of the pencil shell 1 for writing, a plurality of circularly arranged sliding grooves 3 are formed inside the pencil shell 1, and a fixing groove 4 is formed inside the pencil shell 1. The fixing groove 4 is annular and communicates with the plurality of evenly distributed sliding grooves 3. Both the sliding grooves 3 and the fixing groove 4 slide in engagement with the outside of the slider 6. A sleeve 5 is fitted inside the pencil shell 1, and the outside of the sleeve 5 is welded and fixed to the slider 6. The slider 6 and the connecting plate 8 are respectively located at the two ends of the sleeve 5. This can ensure that the graduation line 7 remains horizontal during measurement as much as possible, and avoid deviation in measurement results due to tilting of the graduation line 7.

[0022] Several graduation lines 7 are evenly distributed on the outer side of the sleeve 5. Each graduation line 7 has multiple different unit graduations. By rotating the connecting plate 8, the sleeve 5 is driven to rotate the slider 6 inside the fixed groove 4, thereby adjusting the graduation lines 7 until a suitable unit graduation is achieved for the user's measurement. The pen shell 1 is transparent and made of plastic. The transparency of the pen shell 1 facilitates the user's reading of the graduations and prevents light refraction from the slide groove 3 from affecting the user's reading through the pen shell 1.

[0023] One end of the sleeve 5 is welded and fixed to the connecting plate 8. The side of the connecting plate 8 is frosted, and the frosted surface of the connecting plate 8 is in contact with one end of the pen shell 1. The frosted surface prevents the sleeve 5 from rotating due to shaking or other reasons, or even from slipping out.

[0024] Several connecting slots 9 are formed on the side of the connecting plate 8. The connecting slots 9 are inserted into the sliders 6, allowing the sliders 6 at one end of a sleeve 5 to be inserted into the connecting slots 9, thus connecting two sleeves 5. This compensates for the insufficient measurement length of a single sleeve 5. One set of scale lines 7 on the outer side of the sleeve 5 is specifically used for reading during connection, avoiding the problem of inaccurate scale lines 7 due to the connection of sleeves 5.

[0025] One end of the pen refill cylinder 2 is provided with a pencil tip, which includes a level 11. Both ends of the level 11 are connected and fixed to end plates 10. The side of the end plates 10 is threaded into one end of the pen refill cylinder 2. By rotating the end plates 10, they can be detached from one end of the pen refill cylinder 2. The level is then checked using the level 11. The end plates 10 are made of magnetic metal, and their magnetic attraction prevents the level 11 from rolling during testing. A circular baffle is fixedly connected to the outside of the pen refill cylinder 2, sealing the gap between the pen refill cylinder 2 and the sleeve 5.

[0026] The outer side of the pen casing 1 is welded and fixed to the anti-roll frame 12. The inner wall of the anti-roll frame 12 is rotatably fitted to both ends of the rotating shaft 13. The rotating shaft 13 is damped to prevent the rotating plate 14 from shaking due to external forces. The outer side of the rotating shaft 13 is welded and fixed to the rotating plate 14. The protractor display plate 15 is a transparent semi-circle. Both ends of the protractor display plate 15 are welded and fixed to the anti-roll frame 12 and the rotating plate 14, respectively. The protractor display plate 15 is a foldable flexible sheet made of transparent plastic. Angle scales are set on the outer side of the protractor display plate 15. By rotating the rotating plate 14 until the rotating plate 14 is collinear with the anti-roll frame 12, the damping of the rotating shaft 13 prevents the rotating plate 14 from sliding. At the same time, the protractor display plate 15 is unfolded for measurement.

[0027] The center of the protractor display plate 15 is welded and fixed to the reinforcing rib 16. The reinforcing rib 16 makes the protractor display plate 15 unfold more smoothly and improves its stability. The bottom of the reinforcing rib 16 is fixedly connected to a hollow ring, which is sleeved on the outside of the rotating shaft 13 to ensure that the reinforcing rib 16 unfolds as the rotating plate 14 rotates.

[0028] Working principle: During measurement, a rough measurement can be performed using the transparent pen shell 1 and the scale lines 7. Rotating the connecting plate 8 rotates the sleeve 5, allowing selection of different measurement units on the scale lines 7. The sleeve 5 can also be rotated within the fixing groove 4, causing the slider 6 to slide out of the groove 3, thus removing the sleeve 5 from the pen shell 1. While measuring with the sleeve 5, the tip of the pen shell 1 is used for marking, increasing the flexibility of pencil measurement. Another sleeve 5 can be removed, and the slider 6 inserted into the connecting groove 9, connecting the two sleeves 5 to compensate for insufficient measurement length of a single sleeve 5.

[0029] By rotating the end plate 10, the pencil lead can be taken out from one end of the lead cylinder 2. The level can be measured using the level 11. The rotating plate 14 can also be rotated until it is collinear with the anti-roll frame 12. At the same time, the protractor display plate 15 is extended into a semi-circle. Angles can be roughly measured through the protractor display plate 15, thus expanding the functionality of measuring pencils.
