Description

Technical Field

[0001] This utility model relates to a multifunctional profile guide. Background Technology

[0002] In the construction and decoration industry, construction workers typically need to carry a variety of auxiliary tools, such as profilers, compasses, levels, and protractors, to meet various complex construction needs. Although these tools have different functions, they often suffer from problems such as inconvenience in carrying them or limited functionality, increasing the burden on construction workers.

[0003] Take a profile gauge as an example. It is a tool used for drawing outlines on irregular walls and other complex surfaces to facilitate subsequent construction, such as flooring installation. However, existing profile gauges have limited functionality, only meeting basic shape-drawing needs. When construction workers need to use functions such as a compass (e.g., drawing circles or arcs), a protractor (e.g., measuring angles), or a level (e.g., measuring plane levelness), existing profile gauges cannot provide support, requiring workers to carry additional tools. This not only increases the burden of carrying tools but also reduces work efficiency.

[0004] Therefore, it is necessary to develop a tool that integrates multiple functions, such as combining the functions of a profile compass, circle compass, protractor, and level into one device, which will greatly improve the convenience and efficiency of construction workers.

[0037] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0038] like Figures 1-4 As shown in the figure, this embodiment discloses a multifunctional contour guide, which includes a first support arm 1, a second support arm 2, a first locking device 3, a base 4, and a drawing pen (not shown in the figure).

[0039] The first arm 1 includes a main body 11 that is rectangular in shape and a support tip 12 located at one end of the main body 11. An avoidance hole 111 is provided on the main body 11.

[0040] One end of the second arm 2 is rotatably connected to the other end of the main body 11. Applying an external force to the second arm 2 allows it to rotate around the first arm 1. After the external force is removed, the second arm 2 can remain in its current position. This can be achieved by using a damped connection or by setting a locking structure at the connection point.

[0041] The first locking device 3 is installed on the second arm 2 and is configured to lock and unlock with the second arm 2.

[0042] The base 4 is connected to the first locking device 3. The base 4 has a mounting hole 5. When the first locking device 3 is locked to the second support arm 2, neither the base 4 nor the first locking device 3 can rotate. When the first locking device 3 is unlocked from the second support arm 2, the base 4 can rotate together with the first locking device 3 at a certain angle.

[0043] The drawing pen is detachably inserted through the mounting hole 5. The drawing pen does not specifically refer to a pen as a particular type of product; it only needs to have a part that can draw lines and make marks.

[0044] In this embodiment, the multifunctional profiler has a profile-following mode and a compass-following mode. In the profile-following mode, the support tip 12 rests against the surface to be profiled, and the pen tip of the drawing pen passes through the clearance hole 111. At this time, the support tip moves along the surface of the surface to be profiled, and the pen tip of the drawing pen can simultaneously draw the outline shape of the surface to be profiled.

[0045] Unlock the first locking device 3 from the second support arm 2, rotate the first locking device 3, base 4 and drawing pen at a certain angle so that the tip of the drawing pen does not pass through the clearance hole 111, or rotate the first locking device 3, base 4 and drawing pen at a certain angle to form a non-perpendicular angle with the first support arm 1, and change the connection position between the drawing pen and the mounting hole 5 so that the drawing pen passes through the clearance groove more, so that the multifunctional profile guide of this embodiment can be switched from the profile use state to the compass use state. In the compass use state, the support tip 12 rests against the circular plane to be drawn, and the tip of the drawing pen can draw a circular trajectory on the circular plane to be drawn with the support tip 12 as the center.

[0046] In this embodiment, the above-described structural form integrates the functions of a profile compass and a circle compass into one device, greatly improving the convenience and efficiency of construction workers.

[0047] Furthermore, the multifunctional contour guide in this embodiment also includes a second locking device 6 installed on the base 4, which is used to lock and release the drawing pen to make it easier to replace the drawing pen or change the connection position between the drawing pen and the mounting hole 5.

[0048] Furthermore, the clearance hole 111 extends along the length of the main body 11, and the first locking device 3 can be installed at different positions on the second support arm 2. In this embodiment, the elongated clearance hole 111 can meet the requirement that the tip of the drawing pen can still pass through the clearance hole 111 after the first locking device 3 changes its installation position on the second support arm 2. In this embodiment, adjusting the position of the first locking device 3 on the second support arm 2 can change the position of the drawing pen from the support tip 12. In the shape-taking mode, the distance between the synchronously drawn contour line and the plane to be shaped can be adjusted. In the compass mode, it is equivalent to adjusting the radius of the circle, thereby enabling the drawing of circular trajectories of different sizes, greatly improving the applicability of the multifunctional profile compass of this embodiment.

[0049] Furthermore, in this embodiment, the second arm 2 is provided with a guide hole 21 extending along its length direction, one end of the first locking device 3 passes through the guide hole 21 and is rotatably connected to the base 4, and the first locking device 3 is movably installed in the guide hole 21.

[0050] In this embodiment, by adopting the above-described structural form, the position of the first locking device 3 / base 4 / drawing pen on the second support arm 2 can be adjusted more flexibly, thereby further improving the applicability of the multifunctional profile guide of this embodiment.

[0051] Furthermore, in this embodiment, the multifunctional profiler also includes a top cover 7, which is fitted over the supporting top 12 and connected to the main body 11 to protect the supporting top 12 and facilitate the carrying of the multifunctional profiler. More specifically, in this embodiment, the top cover 7 adopts a triangular structure, with one of the pointed corners designed with a rounded chamfer. The chamfer can also move against the surface to be profiled, so that the profile can be profiled without removing the top cover 7, improving the convenience of use.

[0052] Furthermore, in this embodiment, the first support arm 1 also includes a mounting portion 13 connected to the second support arm 2, and the mounting portion 13 has a connection hole 131. The multi-functional profile guide also includes a connector 8, which is rotatably mounted in the connection hole 131, and one end of the connector 8 passes through the connection hole 131 and is connected to the second support arm 2.

[0053] In this embodiment, the mounting part 13 and the connector 8 are configured to cooperate to achieve a stable connection between the first arm 1 and the second arm 2.

[0054] Furthermore, in this embodiment, an angle plate 9 is provided circumferentially along the connecting hole 131 on the side of the mounting part 13 opposite to the second support arm 2. The connecting member 8 rotates synchronously with the second support arm 2, and an indicator mark 1011 is provided on the end face of the connecting member 8 on the same side as the angle plate 9. The second support arm 2 is provided with an alignment protrusion 10 that mates with the angle plate 9 on the side opposite to the first support arm 1 (see...). Figure 3 ).

[0055] In this embodiment, a connector 8 that can rotate with the second arm 2 is provided, and a 360-degree angle plate 9 is provided on the mounting part 13. The angle of rotation of the second arm 2 relative to the first arm 1 can be viewed through the indicator mark 1011 on the connector 8. Thus, the multifunctional profile gauge of this embodiment can be used as a protractor. When measuring the angle, one side of the object to be measured is placed on the positioning protrusion 10, and then the first arm 1 is rotated to measure the outer angle of the object to be measured.

[0056] Furthermore, in this embodiment, the connector 8 includes a cylindrical portion 81 and a disc indicator portion 82 with a diameter larger than that of the cylindrical portion 81. The cylindrical portion 81 is connected to the second support arm 2. An indicator mark 1011 is disposed on the disc indicator portion 82. The connecting hole 131 includes a first hole segment and a second hole segment. The size of the first hole segment is larger than that of the second hole segment. The disc indicator portion 82 is installed in the first hole segment, and the cylindrical portion 81 is installed in the second hole segment. The indicator mark 1011 is flush with the angle disc 9, thereby making it easier to view the angle of rotation of the connector 8 relative to the first support arm 1.

[0057] Furthermore, in this embodiment, the connector 8 is provided with a snap-fit ​​protrusion 1012, and the second support arm 2 is provided with a snap-fit ​​groove 1013, and the snap-fit ​​protrusion 1012 matches the snap-fit ​​groove 1013.

[0058] In this embodiment, by adopting the above-described structure, the connector 8 and the second arm 2 can be quickly assembled together, so as to achieve synchronous rotation of the connector 8 with the second arm 2 in a quick manner.

[0059] Furthermore, in this embodiment, a mounting groove is provided on the second support arm 2, and a through hole 22 is provided at the bottom of the mounting groove. The multi-functional profile guide also includes a locking member disposed in the mounting groove, and the connecting member 8 passes through the through hole 22 and is detachably connected to the locking member.

[0060] In this embodiment, by adopting the above-described structure, the second arm 2, after being rotated to the position required by the specific working condition, can be kept in the current position by the locking component, so as to prevent the second arm 2 and the drawing pen from shifting during the process of taking shape or drawing a circle.

[0061] Furthermore, the multifunctional profile guide in this embodiment also includes a horizontal deflector 1014 mounted on the second support arm 2, and the axis of the horizontal deflector 1014 is parallel to the axis of the second support arm 2.

[0062] In this embodiment, after setting the horizontal deflection bubble 1014, the end face of the second support arm 2 is away from the first support arm 1. Figure 3 The upper surface of the guide (in the figure) is placed on the plane to be measured as a reference surface, which can be used to measure the levelness of the plane to be measured, further expanding the function of the multifunctional profile gauge in this embodiment and further improving its applicability.
