Description

Technical Field

[0001] The utility model belongs to the technical field of interior decoration, and particularly relates to a positioning and scribing device. Background Technique

[0002] During the construction process of interior decoration, in order to ensure the accuracy of construction, workers need to use a scribing pen to scribe lines on the building wall to distinguish different decoration areas. At present, it is mainly to use a scale to assist manual holding of the scribing pen for scribing. The scribing efficiency is low and the error is large.

[0003] When the scribing position is relatively high or the scribing distance is relatively long, it is also necessary to use a shelf or a stool for assistance. One person holds the scale and the other person scribes the line. Generally, two people are required to cooperate to complete it, which is time-consuming and laborious, and it is also difficult to achieve high precision. Summary of the Invention

[0004] In order to overcome the problems that at present, it is mainly to use a scale to assist manual holding of the scribing pen for scribing, the scribing efficiency is low and the error is large. When the scribing position is relatively high or the scribing distance is relatively long, generally two people are required to cooperate to complete it, which is time-consuming and laborious, and it is also difficult to achieve high precision. The utility model provides a positioning and scribing device. The lower surface of the ruler is attached to the wall. At this time, the bottom end of the scribing pen is in contact with the wall surface. Subsequently, the operator rotates the crank, so that the driving bevel gear drives the driven bevel gear to rotate, and drives the bidirectional lead screw to rotate, further driving the slider and the roller to move along the chute. The movement of the slider drives the connecting block and the scribing pen to move to realize the scribing function. Vertical scribing or horizontal scribing can be carried out. The scribing is flat and relatively accurate, and one person can complete the operation. It can also be operated at relatively high positions, which is time-saving and labor-saving.

[0005] To achieve the above object, the utility model is realized by the following technical solutions: A positioning and scribing device mainly includes a ruler, a driving component, a scribing pen, and a chute. The driving component includes a slider, a bidirectional lead screw, a connecting block, a crank, a driving bevel gear, and a driven bevel gear. A chute is opened in the ruler. The bidirectional lead screw is installed in the chute. The slider is slidably installed in the chute and is threadedly connected to the bidirectional lead screw. A driven bevel gear is installed in the middle of the bidirectional lead screw. The crank is installed on the ruler through a bearing. The end of the crank is installed with a driving bevel gear meshing with the driven bevel gear. A rectangular notch is opened on the side of the ruler. One end of the connecting block is connected to the slider, and the other end passes through the rectangular notch. The scribing pen is installed on the connecting block.

[0006] A ball for reducing the friction between the end of the scribing pen and the wall surface is embedded at the bottom end of the scribing pen.

[0007] Rollers that are in rolling contact with the inner wall of the chute are provided on both sides of the slider.

[0008] The described straightedge is provided with a handrail for facilitating the pressing of the straightedge.

[0009] Advantages of the present utility model:

[0010] Attach the lower surface of the straightedge to the wall. At this time, the bottom end of the marking pen contacts the wall surface. Subsequently, the operator rotates the crank handle, causing the driving bevel gear to drive the driven bevel gear to rotate, and driving the bidirectional lead screw to rotate. Further, it drives the slider and the roller to move along the chute. The movement of the slider drives the connecting block and the marking pen to move to achieve the marking function. Vertical or horizontal marking can be performed. The marking is flat and relatively accurate, and it can be operated by one person. It can also be operated at relatively high positions, which is time-saving and labor-saving. Description of the Drawings

[0015] In order to make the purpose, technical solution and advantages of the present utility model clearer, the preferred embodiments of the present utility model will be described in detail below with reference to the drawings for the convenience of those skilled in the art to understand.

[0016] The present utility model discloses a positioning and marking device, which mainly includes a straightedge 1, a driving assembly 2, a marking pen 3, and a chute 4. The driving assembly 2 includes a slider 21, a bidirectional lead screw 22, a connecting block 23, a crank handle 24, a driving bevel gear 25, and a driven bevel gear 26. A chute 4 is opened in the straightedge 1. The bidirectional lead screw 22 is installed in the chute 4. The slider 21 is slidably installed in the chute 4 and is threadedly connected to the bidirectional lead screw 22. A driven bevel gear 26 is installed in the middle of the bidirectional lead screw 22. The crank handle 24 is installed on the straightedge 1 through a bearing. An active bevel gear 25 meshing with the driven bevel gear 26 is installed at the end of the crank handle 24. A rectangular notch 101 is opened on the side of the straightedge 1. One end of the connecting block 23 is connected to the slider 21, and the other end passes through the rectangular notch 101. The marking pen 3 is installed on the connecting block 23.

[0017] During use, the operator holds the handrail 5 and presses the lower surface of the straightedge 1 against the wall. At this time, the bottom end of the marking pen 3 contacts the wall surface. Then, the operator rotates the crank 24, causing the driving bevel gear 25 to drive the driven bevel gear 26 to rotate, which in turn drives the bi-directional lead screw 22 to rotate. Further, the slider 21 and the roller 27 are driven to move along the chute 4. The movement of the slider 21 drives the connecting block 23 and the marking pen 3 to move, realizing the marking function. The bottom end of the marking pen 3 is embedded with a ball 31 for reducing the friction between the end of the marking pen 3 and the wall surface, enabling the marking pen 3 to move smoothly during the marking process and preventing the end of the marking pen 3 from scratching the wall surface. Vertical or horizontal marking can be performed, the marking is flat and relatively accurate, and it can be operated by one person. It can also be operated at relatively high positions, which is time-saving and labor-saving.

[0018] As Figure 3 shown, the bottom end of the marking pen 3 is embedded with a ball 31 for reducing the friction between the end of the marking pen 3 and the wall surface; this enables the marking pen 3 to move smoothly during the marking process and prevents the end of the marking pen 3 from scratching the wall surface.

[0019] As Figure 3 shown, the two sides of the slider 21 are provided with rollers 27 that are in rolling contact with the inner wall of the chute 4; this helps to reduce the friction of the slider 21 during the sliding process.

[0020] As Figure 2 shown, the straightedge 1 is provided with a handrail 5 for easily pressing the straightedge 1; this enables the operator to press the straightedge 1 against the wall through the handrail 5, improving the stability of the straightedge 1 during the measurement process.

[0021] Working process:

[0022] During use, the operator holds the handrail 5 and presses the lower surface of the straightedge 1 against the wall. At this time, the bottom end of the marking pen 3 contacts the wall surface. Then, the operator rotates the crank 24, causing the driving bevel gear 25 to drive the driven bevel gear 26 to rotate, which in turn drives the bi-directional lead screw 22 to rotate. Further, the slider 21 and the roller 27 are driven to move along the chute 4. The movement of the slider 21 drives the connecting block 23 and the marking pen 3 to move, realizing the marking function. The bottom end of the marking pen 3 is embedded with a ball 31 for reducing the friction between the end of the marking pen 3 and the wall surface, enabling the marking pen 3 to move smoothly during the marking process and preventing the end of the marking pen 3 from scratching the wall surface. Vertical or horizontal marking can be performed, the marking is flat and relatively accurate, and it can be operated by one person. It can also be operated at relatively high positions, which is time-saving and labor-saving.
