This design facilitates carrying the entire marking ruler without affecting its marking effect.

Description

Technical Field

[0001] This utility model relates to the field of measuring tools for decoration and construction, and in particular to a marking ruler for woodworking. Background Technology

[0002] A carpenter's ruler is a specialized tool used by carpenters for measuring and drawing lines. Common sizes include 600mm, 900mm, and 1200mm. Common types include straight rulers, squares, and tape measures. Straight rulers are often made of transparent organic plastic or glass for easy and precise line drawing.

[0003] Existing woodworking marking rulers have a simple structure, usually consisting of two rulers joined together and rotated to measure length and angle. However, if the marking ruler is too long, it will be inconvenient to carry, and if it is too short, it will affect its effectiveness. To solve the above problems, a woodworking marking ruler is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a woodworking marking ruler to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a woodworking marking ruler, comprising a first scale strip, a fixed post fixedly connected to the surface of the first scale strip, a second scale strip rotatably connected to the surface of the fixed post, clearance holes being provided on the surfaces of both the first and second scale strips, and an extension strip slidably connected to the surfaces of both the first and second scale strips, the extension strip being provided with a positioning adjustment mechanism.

[0006] Preferably, the positioning adjustment mechanism includes a plug plate fixedly connected to the surface of the extended ruler strip, and protrusions are fixedly connected to the surfaces of both the first and second ruler strips, with spring telescopic rods fixedly connected to the inner walls of the protrusions.

[0007] Preferably, one end of the spring telescopic rod is fixedly connected to a hemispherical head, and the surface of the plug plate is provided with a slot, the hemispherical head being adapted to the slot.

[0008] Preferably, one side of the plug-in plate is provided with a chamfer, and the surface of the extended ruler strip is provided with multiple auxiliary line holes.

[0009] Preferably, the inner wall of the first scale strip is fixedly connected with an anti-slip pad, and the inner wall of the second scale strip is threadedly connected with a threaded rod, the bottom end of which is pressed into contact with the upper surface of the anti-slip pad.

[0010] Preferably, the surfaces of the first and second scale strips are provided with circular holes, square holes, and triangular holes, and the surface of the extended scale strip is provided with through holes.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

[0012] In this invention, when storing the extended ruler strip, pushing the extended ruler strip causes the chamfered surface to contact the surface of the hemispherical head, which in turn shortens the compression spring telescopic rod, allowing the hemispherical head to re-lock into the slot and maintain stable storage. At the same time, the threaded rod presses and fixes the surface of the anti-slip pad, limiting the angle rotation of the second scale ruler strip during use. The advantage of this is that it is convenient to carry the entire scribing ruler without affecting its scribing effect. Attached Figure Description

Detailed Implementation

[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] Example: Reference Figures 1-5 The woodworking marking ruler shown includes a first scale strip 1, a fixed post 4 fixedly connected to the surface of the first scale strip 1, a second scale strip 2 rotatably connected to the surface of the fixed post 4, clearance holes 18 being provided on the surfaces of both the first scale strip 1 and the second scale strip 2, and an extension strip 5 slidably connected to the surfaces of both the first scale strip 1 and the second scale strip 2, with a positioning adjustment mechanism provided on the surface of the extension strip 5.

[0022] With the above structure, the second scale bar 2 is kept stable by setting the fixed column 4. The second scale bar 2 is set to open the angle with the first scale bar 1, which facilitates angle measurement. The extended scale bar 5 is set to extend when in use and store it when not in use, making it easy to carry.

[0023] Preferably, the positioning adjustment mechanism includes a plug plate 13 fixedly connected to the surface of the extended ruler strip 5, and protrusions 9 are fixedly connected to the surfaces of the first scale strip 1 and the second scale strip 2, and spring telescopic rods 10 are fixedly connected to the inner walls of the protrusions 9.

[0024] The plug plate 13 facilitates the storage and positioning of the extended ruler 5, and the protrusion 9 provides installation space for the spring telescopic rod 10.

[0025] Preferably, one end of the spring telescopic rod 10 is fixedly connected to a hemispherical head 11, and the surface of the plug plate 13 is provided with a slot 12, which is adapted to the hemispherical head 11 and the slot 12.

[0026] By setting the slot 12, the extended ruler 5 is stably stored after the hemispherical head 11 is inserted into the slot 12.

[0027] Preferably, one side of the plug-in plate 13 is provided with a chamfer 14, and the surface of the extended ruler 5 is provided with a plurality of auxiliary line holes 7.

[0028] By setting a chamfer 14, when the surface of the chamfer 14 contacts the surface of the hemispherical head 11, the hemispherical head 11 is forced to compress the spring telescopic rod 10, causing it to shorten.

[0029] Preferably, the inner wall of the first scale strip 1 is fixedly connected with an anti-slip pad 8, and the inner wall of the second scale strip 2 is threadedly connected with a threaded rod 3, the bottom end of which is pressed into contact with the upper surface of the anti-slip pad 8.

[0030] By setting the threaded rod 3 to press against the surface of the anti-slip pad 8, the rotation angle position of the second scale strip 2 is limited.

[0031] Preferably, the surfaces of the first scale strip 1 and the second scale strip 2 are provided with a circular hole 15, a square hole 16 and a triangular hole 17, and the surface of the extended scale strip 5 is provided with a through hole 6.

[0032] By setting circular holes 15, square holes 16 and triangular holes 17, it is convenient to plan different markings. By setting through holes 6, the extended ruler strip 5 can be pulled out and extended by pulling through through holes 6.

[0033] The working principle of this utility model is as follows: A woodworking marking ruler, when in use, pull out the through hole 6 to pull out the extended ruler strip 5. At this time, the hemispherical head 11 located in the slot 12, under the action of the pulling force, compresses the spring telescopic rod 10, shortens, and releases the locking restriction. Thus, during use, it ensures that the length of the first scale strip 1 and the second scale strip 2 is extended to meet the drawing requirements. When it is necessary to adjust the rotation angle of the second scale strip 2, rotate the threaded rod 3 to release the squeezing state of the anti-slip pad 8. After adjusting the angle of the second scale strip 2, reverse the threaded rod 3 to rub against the surface of the anti-slip pad 8 and fix it, restricting the angle rotation of the second scale strip 2. When it is necessary to store the extended ruler strip 5, push the extended ruler strip 5. After the surface of the chamfer 14 contacts the surface of the hemispherical head 11, the compression spring telescopic rod 10 shortens, so that the hemispherical head 11 is re-locked in the slot 12 and positioned to maintain stable storage.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
