Description

Technical Field

[0001] This utility model relates to the field of surveying tools technology, and in particular to an extendable woodworking combination T-shaped angle ruler. Background Technology

[0002] Currently, woodworking typically requires multiple tools, such as rulers, levels, calipers, compasses, clamps, and pencils, for crosshair positioning before drilling. This traditional method relies heavily on the operator's visual judgment and personal experience, which has significant limitations: firstly, positioning accuracy is difficult to guarantee, leading to deviations; secondly, during actual drilling, the drill bit is prone to displacement due to vibration because it relies solely on crosshair markings, resulting in misalignment and gaps in the tenon joint. Furthermore, this process demands a high level of skill from the operator, is difficult to learn and master, and is inefficient, failing to meet the precision and efficiency requirements of modern woodworking.

[0003] In response, the existing technology (authorized announcement CN203726475U) discloses a multi-purpose woodworking drilling and marking ruler that can be used for multiple purposes with one ruler. Individual parts can be used independently or in combination to simultaneously complete length measurement, center position measurement, and set symmetrical distances by taking the center point. It has various sliders and grooves, and the parts can be directly connected to the ruler body through the sliders. It is very simple and convenient, and simpler and more efficient than the copy connection methods on the market.

[0004] However, the line ruler disclosed above still has the following technical problems in use: although it has multiple functions, its length is fixed and cannot be spliced ​​and extended according to the actual processed object, so its scope of use is still limited. Summary of the Invention

[0005] The main purpose of this utility model is to overcome the shortcomings of the existing technology and provide an extendable woodworking combination T-shaped angle ruler.

[0006] The technical solution adopted by this utility model to achieve its technical purpose is: an extendable woodworking combination T-shaped angle ruler, including a main ruler plate, a positioning component is provided inside the main ruler plate, and a measuring component is provided at one end of the main ruler plate and an extension ruler plate is provided at the other end. The extension ruler plate is detachably connected to the main ruler plate.

[0007] Preferably, the main ruler plate has a sliding groove inside, and the positioning component is slidably connected in the sliding groove;

[0008] The positioning assembly includes an adjusting nut, a slider, a T-shaped slide, a finger block, and a rotating hole;

[0009] One end of the T-shaped slider passes through the slider and is threadedly connected to the adjusting nut. The other end of the T-shaped slider is attached to the bottom of the slider. The slider is slidably mounted inside the sliding groove by the T-shaped slider. The adjusting nut can lock the T-shaped slider and the slider in the sliding groove.

[0010] The rotating holes are formed at both ends of the slider and are located directly above the sliding groove. By determining the distance, it is convenient for the punching machine to pass through the rotating holes and the sliding groove to perform punching.

[0011] The top of the slider is attached to the scale surface of the main ruler plate, and points to the scale line of the main ruler plate through an integrally set finger block. The position of the finger block and the position of the rotating hole are set accordingly to facilitate the determination of the drilling distance.

[0012] The slider and the T-shaped slider together form an I-shaped structure. The sliding slot is T-shaped, and the T-shaped slider is slidably mounted in the sliding slot, so that the slider can also slide in the sliding slot.

[0013] In order to fix the position of the finger block, the tightness of the connection between the slider and the T-shaped slider can be adjusted by the setting of the adjusting nut. The T-shaped slider is then restricted by the sliding groove, so that the slider and the T-shaped slider can be fixed in the sliding groove, thereby fixing the position of the finger block.

[0014] Preferably, the protractor assembly includes a long plate, a protractor plate, a rubber-headed bolt, and a reference groove;

[0015] The protractor is integrally connected to one side of the long plate, and the reference groove is opened on the other side of the long plate. The long plate is locked and fixed to the back of the main ruler plate by rubber-headed bolts.

[0016] A pointer is integrally provided at the end of the main ruler plate, and the pointer points to the scale line on the protractor plate.

[0017] One end of the rubber-headed bolt passes through a sliding groove inside the main ruler plate and is threaded into the long plate. By adjusting the tightness of the rubber-headed bolt, the long plate and the main ruler plate can rotate relative to each other. Furthermore, by relying on the pointer and the scale lines on the protractor, the main ruler plate can rotate relative to the long plate at a specific angle, facilitating the drawing of lines at different angles. Additionally, the reference groove can be observed through the sliding groove, facilitating calibration and maintaining perpendicularity between the main ruler plate and the long plate.

[0018] Preferably, the other end of the main ruler plate and one end of the extension ruler plate are provided with insertion holes. A pin is inserted into the insertion hole, and a set screw is provided to tighten and fix both ends of the pin in the insertion hole, so that the extension ruler plate is fixedly installed on the main ruler plate. The set screw and the pin can realize the detachable connection between the main ruler plate and the extension ruler plate.

[0019] Preferably, a level is fixedly installed on the extended ruler plate.

[0020] Preferably, the main ruler plate and the extension ruler plate are connected in a cross shape. A limiting groove is provided on the back of the extension ruler plate. The limiting groove allows the extension ruler plate to fit against the front of the main ruler plate, which is slidably connected to it. The positioning component then locks and fixes the extension ruler plate to the main ruler plate.

[0021] Due to the presence of the slider in the positioning assembly, a portion of the slider is attached to the surface of the main ruler plate. In order to ensure that the extended ruler plate is flat and attached to the main ruler plate, a limiting groove matching the slider is opened on its back. At the same time, the limiting groove also prevents the extended ruler plate from shaking on the surface of the main ruler plate.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] This woodworking T-shaped angle ruler, through the detachable connection of the extension plate, can extend the main plate, increasing its measuring length and extending the drilling position. It can also form a cross connection with the main plate, improving its applicability and giving the woodworking T-shaped angle ruler a variety of measuring functions.

[0024] This woodworking T-shaped angle ruler, through its protractor component, allows the main ruler plate to rotate at a specific angle relative to the long plate. This facilitates the machining of lines and holes at different angles and ensures accuracy at various angular positions, making it suitable for a variety of scenarios. Furthermore, the reference groove can be observed through the sliding slot, facilitating calibration between the main ruler plate and the long plate to maintain perpendicularity.
