Description

Technical Field

[0001] This utility model relates to the technical field of marking devices for building decoration and renovation, specifically a marking device for the design of building decoration and renovation projects. Background Technology

[0002] In building decoration and renovation projects, there are many types of marking devices. Marking devices can be divided into measuring and marking tools, signage and placards, and positioning and electronic markers. Among them, measuring and marking tools mainly include tape measures, steel rulers, and engineering squares. Tape measures are used to measure lengths, steel rulers can be used to mark rigid straight lines on a plane or for measurement, while engineering squares are used to draw vertical lines or measure the angle between two intersecting lines. When drilling socket holes for power outlets or window mounting holes on the wall, multiple marking lines need to be marked on the wall in advance. These marking lines need to be parallel or perpendicular to the ground to prevent the mounting holes from being crooked, which would affect the aesthetics and practicality of the power outlets or windows after installation.

[0003] For marking lines drawn for indoor or small installation holes, manual marking is mainly used. During the marking process, a measuring tape, steel ruler, and engineering square are used together. Workers directly press the steel ruler against the wall and use a marker to draw the marking line. Manual measurement is used to judge whether the marking line is parallel or perpendicular to the ground. The error caused by manual visual inspection is relatively large, which leads to the marking line being crooked, thus affecting the accuracy of the installation of power sockets or windows.

[0004] Therefore, this utility model provides a marking device for architectural decoration and renovation engineering design to solve the above problems. Utility Model Content

[0017] 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. Example 1:

[0018] Please see Figure 1-7 A marking device for architectural decoration and renovation engineering design includes a protractor A1, which is semi-circular. A horizontal rod 2 is fixedly connected inside the protractor A1. The horizontal rod 2 and the bottom line of the protractor A1 are vertically arranged. A rotating rod 3 is hinged inside the horizontal rod 2. An angle positioning component 4 is installed between the rotating rod 3 and the protractor A1. A horizontal measuring component 5 is installed on the outside of the protractor A1. The horizontal measuring component 5 includes a connecting shell 501 installed on the outside of the protractor A1. A winding column 502 is rotatably connected inside the connecting shell 501. A suspension rope 503 is wound around the outside of the winding column 502. A counterweight 504 is fixedly connected to one end of the suspension rope 503. A protractor B505 is fixedly connected to the outside of the protractor A1. The protractor B505 is fan-shaped. A scale groove A506 is opened on the outside of the protractor B505. A positioning column A507 is installed inside the scale groove A506. The positioning column A507 is installed on the outside of the suspension rope 503. A limit component 6 is installed inside the connecting shell 501.

[0019] The hinge points of the protractor A1, the horizontal bar 2, and the rotating bar 3 are set on the same axis.

[0020] The included angle of the scale groove A506 is set at 40°.

[0021] The angle positioning component 4 includes a scale groove B401 opened on the outside of the protractor A1, a positioning post B402 fixedly connected to the outside of the rotating rod 3, the positioning post B402 being installed inside the scale groove B401, a connecting bolt 403 fixedly connected to one side of the rotating rod 3, the connecting bolt 403 passing through the center of the protractor A1, and a connecting nut 404 threadedly connected to the outside of the connecting bolt 403.

[0022] The included angle of the scale groove B401 is set at 70°.

[0023] The limiting component 6 includes a gear 601 fixedly connected to the bottom of the winding column 502. A torsion spring A602 is installed between the gear 601 and the connecting shell 501. A spring telescopic rod 603 is fixedly connected to the bottom of the inner cavity of the connecting shell 501. A limiting plate 604 is fixedly connected to the top of the spring telescopic rod 603. A limiting tooth 605 is hinged inside the limiting plate 604. The limiting tooth 605 meshes with the gear 601. A torsion spring B606 is fixedly connected between the limiting plate 604 and the limiting tooth 605. A pin 607 is fixedly connected to the outside of the limiting plate 604. The pin 607 passes through the limiting tooth 605. The torsion spring B606 is sleeved on the outside of the pin 607. The top of the pin 607 is slidably connected to the connecting shell 501.

[0024] A positioning plate 9 is fixedly connected to the outer side of the protractor A1. The outer side of the positioning plate 9 has a locking hole and a positioning hole. There are two positioning holes, which are located on both sides of the locking hole.

[0025] In this embodiment, the device can be used to measure the included angle of the edge of a preset hole, and also to assist in drawing marking lines. When measuring the included angle of the edge of a preset hole, the horizontal rod 2 can be placed against the corner of the preset hole on the wall, so that the inner plane of the horizontal rod 2 is flush with the bottom of the preset hole. Loosen the connecting nut 404 on the outside of the connecting bolt 403, so that the rotating rod 3 inside the horizontal rod 2 can move. The horizontal rod 2 can be fixed to the wall by two screws. Rotate the rotating rod 3 so that the inner plane of the rotating rod 3 is flush with the side of the preset hole on the wall. During the rotation of the rotating rod 3, the outer side of the rotating rod 3 is fixed. Position column B402 slides inside the scale groove B401 on the outside of the protractor A1, thereby accurately measuring the angle of the pre-drilled hole on the wall, and thus determining whether the pre-drilled hole on the wall is standard. This device can also be used to measure building decoration boards, etc. When it is necessary to draw marking lines on the wall, such as marking lines for the installation holes of power strips or doors and windows, since the included angle of the four sides of the power strip, doors, and windows is 90°, first, rotate the rotating rod 3 inside the horizontal rod 2 so that the horizontal rod 2 and the rotating rod 3 are perpendicular, and then pull the counterweight 504 to connect the housing 501. The internal suspension rope 503 is pulled out, pressing the horizontal bar 2 against the ground. The counterweight 504 automatically tauts the rope 503, suspending it from the wall. The position of the positioning post A507 on the outside of the rope 503 within the scale groove A506 on the outside of the protractor B505 determines whether the horizontal bar 2 is parallel to the ground. By adjusting the tilt angle of the horizontal bar 2 and relying on the movement of the positioning post A507 within the scale groove A506, the horizontal bar 2 is made parallel to the ground. After adjustment, the protractor A1 can be fixed to the wall with screws, freeing the worker's hands and allowing for further adjustments. When the rope 503 is pulled, the groove inside the limiting plate 604 is set at a right angle, so the limiting tooth 605 can only rotate 90°, preventing the winding column 502 from rotating automatically. When the rope 503 is retracted, the pin 607 is pressed at the same time, so that the limiting tooth 605 and the gear 601 are displaced, thereby causing the torsion spring A602 to drive the winding column 502 to rotate and reset, thus automatically retracting the rope 503. The retraction method is simple and also prevents the rope 503 from being tangled and knotted due to manual winding. The device is small in size, easy to carry, and highly functional. Example 2:

[0026] Please see Figure 6-7 This embodiment provides a technical solution for a marking device for architectural decoration and renovation engineering design based on embodiment one: a clamping member 7 is installed on the outside of the horizontal rod 2 and the rotating rod 3, and a tape measure 8 is installed inside the clamping member 7.

[0027] The clamping component 7 includes a connecting plate 701 symmetrically fixedly connected to the outside of the measuring tape 8. The horizontal bar 2 and the rotating bar 3 are symmetrically fixedly connected to the outside of the hinge plate 702. There are two hinge plates 702 on each side. A locking rod 703 is hinged between the two hinge plates 702. A three-jaw chuck 704 is fixedly connected to the outside of the locking rod 703. The three-jaw chuck 704 and the connecting plate 701 are engaged. A torsion spring C705 is fixedly connected between the hinge plate 702 and the locking rod 703.

[0028] In this embodiment, some mounting holes have a large area, while the length of the engineering square or steel ruler is short, making it impossible to measure long marking lines at once. In this case, it is necessary to rely on the steel ruler or tape measure 8 to complete the measurement. For smooth walls, two workers are required to complete the task. At the same time, it is difficult to ensure that the stretched tape measure or tape measure 8 is parallel to the ground. Marking lines drawn by visually inspecting the tape measure or tape measure 8 have a large error. After fixing the angle between the horizontal rod 2 and the rotating rod 3, and fixing the protractor A1 to the ground, the tape measure 8 is clamped and fixed by the three-jaw chuck 704 fixed on the outside of the two sets of clamping rods 703. When measuring or drawing marking lines, a single person can stretch the tape measure 8 to complete the task. This reduces the number of personnel required during the measurement process and also ensures that the stretched tape measure 8 is relatively parallel to the ground, reducing the error caused by manual measurement.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] Working principle: The device can be used in two ways depending on the needs. When measuring the accuracy of pre-drilled holes in a wall, the protractor A1 is placed against the outside of one of the included angles of the hole, and the inner side of the horizontal rod 2 is aligned with the bottom of the hole. Then, the rotating rod 3 is rotated until its inner side is aligned with the side of the included angle of the hole. The position of the positioning post B402 within the scale groove B401 is used to measure the accuracy of the pre-drilled hole. This allows for timely adjustments by workers when errors occur in the hole's accuracy. The adjustable angles of the horizontal rod 2 and rotating rod 3 can also be used for tile laying at interior corners, facilitating the cutting of tiles or boards with different angles. When marking lines need to be drawn on the wall, the protractor A1 and the inner horizontal rod 2 are placed against... Leaning against the wall, and pulling the suspension rope 503 inside the connecting shell 501, the weight of the counterweight 504 tauts the rope 503, causing it to hang taut on the outside of the wall. This allows a decorative nail to pass through the locking hole on the outside of the positioning plate 9, thus fixing the positioning plate 9 on the outside of the protractor A1 to the wall. Simultaneously, the worker adjusts the level bar 2, adjusting its rotation angle on the outside of the wall. Based on the position of the positioning post A507 on the outside of the suspension rope 503 within the scale groove A506 on the outside of the protractor B505, the level bar 2 is parallel to the ground when the positioning post A507 is at the center of the scale groove A506, i.e., the 0° scale line. Two screws are then used to fix the protractor A1 connected to the positioning plate 9 to the wall, according to the two marked lines. The included angle between the horizontal rod 2 and the rotating rod 3 is adjusted. After determining the included angle, the rotation angle of the rotating rod 3 inside the horizontal rod 2 is fixed using the connecting nut 404 and the connecting bolt 403. The included angle between the horizontal rod 2 and the rotating rod 3 can be freely adjusted between 20° and 90°. The adjustment method is simple. When it is necessary to draw a long marking line, the three-jaw chuck 704 fixed on the outside of the clamping rod 703 can be clamped to the outside of the connecting plate 701 on the outside of the tape measure 8. The torsion spring C705 generates torque to enhance the firmness of the two sets of three-jaw chucks 704 clamping and fixing the tape measure 8. By stretching the tape measure 8 and using a marker to draw lines or mark on the wall, when the hanging rope 503 is pulled out from the inside of the connecting shell 501, the torsion spring A60 between the winding column 502 and the connecting shell 501 is activated. 2. Torque is generated because the included angle between the two sides of the groove inside the limiting plate 604 is 90°, causing the limiting tooth 605 to rotate only in one direction inside the limiting plate 604. This prevents the suspension rope 503 from automatically retracting during the measurement process. When retracting the suspension rope 503, the pressure generated by pressing the pin 607 on the outside of the connecting shell 501 causes the spring telescopic rod 603 to retract. At this time, the limiting tooth 605 is displaced from the gear 601 at the bottom of the winding column 502, and the torsion spring A602 is released, causing the winding column 502 to rotate and reset, thereby retracting the suspension rope 503. The retraction of the suspension rope 503 does not require manual operation, saving effort and preventing the suspension rope 503 from becoming tangled or knotted due to manual winding. Furthermore, the device is small in size, making it convenient to fold, store, and carry.Furthermore, this device has multiple functions and is highly practical.
