Description

Technical Field

[0001] This utility model relates to the field of asbestos board cutting and marking technology, specifically an auxiliary structure for asbestos board cutting and marking. Background Technology

[0002] Asbestos boards, as an important industrial material, are widely used in many fields due to their excellent heat insulation, fire resistance, and corrosion resistance. In the construction industry, asbestos boards are often used as thermal insulation layers for walls and roofs, effectively reducing indoor and outdoor heat exchange and lowering building energy consumption. In the chemical industry, their excellent corrosion resistance makes them an ideal lining material for pipes, storage tanks, and other equipment, preventing chemical corrosion. In the power industry, asbestos boards are used for thermal insulation of electrical equipment, ensuring safe and stable operation in high-temperature environments. In practical applications, asbestos boards need to be precisely cut to meet the dimensional requirements of different equipment and building structures. The cutting quality directly affects the installation effect and performance of the asbestos boards. Inaccurate cutting dimensions may lead to gaps during installation, reducing the heat insulation and sealing effect; uneven cut edges may affect the connection between the asbestos board and other components, and may even cause safety hazards during long-term use.

[0003] Currently, many small processing sites or on-site construction projects still rely on manual cutting and marking directly on asbestos boards. Operators typically use rulers and markers, relying on experience and visual inspection to determine cutting dimensions and line positions. This method has drawbacks; visual inspection and manual operation make it difficult to guarantee the straightness and dimensional accuracy of the markings. To improve marking accuracy and efficiency, some sites use simple templates to assist in marking. These templates are usually made of rigid materials, such as wood or plastic boards, based on common asbestos board dimensions. When using them, the template is placed on the asbestos board, and lines are drawn along the edges. While this method improves the straightness and dimensional accuracy of the markings to some extent, the following problems still exist: When using the marking auxiliary template for marking, it is necessary to accurately position the template at the designated position on the asbestos board. Otherwise, it will lead to marking deviation. Since the surface of the asbestos board may be uneven or have impurities, the template is prone to slippage or misalignment during the positioning process, which affects the marking accuracy. In addition, it lacks a quick positioning function when aligning the marking auxiliary template with the edge of the asbestos board. Its practicality during marking operations needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary structure for cutting and scribing asbestos boards, which can accurately position and prevent the scribing auxiliary template from sliding and misaligning when positioning the asbestos board, reduce scribing deviation, and ensure scribing accuracy, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an asbestos board cutting and marking auxiliary structure, comprising: a marking auxiliary template, the surface of which is provided with a positioning component, the positioning component being connected to the marking auxiliary template via a connecting component, and limiting components at both ends of the surface of the marking auxiliary template, the positioning component comprising: a bonding ring, the bonding ring being located on the surface of the marking auxiliary template, a threaded cylinder being threadedly connected to the inner wall of the bonding ring, a knob being fixedly connected to the end of the threaded cylinder, a protruding rod being rotatably connected to the end of the threaded cylinder away from the knob, a silicone sheet being connected to the end of the protruding rod away from the threaded cylinder, the silicone sheet being connected to the marking auxiliary template, and the connecting component comprising: multiple embedded cylinders, the multiple embedded cylinders being uniformly embedded and fixedly fixed to the surface of the marking auxiliary template, a magnetic ring being embedded and fixedly fixed to the end of the embedded cylinder near the bonding ring, the magnetic ring being magnetically attracted to the bonding ring, and the contact surface of the silicone sheet and the embedded cylinder being pressed together.

[0006] Preferably, a bolt is inserted into the surface of the silicone sheet, and the bolt passes through the silicone sheet and is threadedly connected to the protruding rod.

[0007] Preferably, the limiting component includes: a pair of plates, a pair of support rods fixed to the top of the plates, the support rods passing through the scribing auxiliary template through through holes, and nuts threadedly connected to the support rods, the nuts abutting against the scribing auxiliary template.

[0008] Compared with the prior art, the beneficial effects of this utility model are: the asbestos board cutting and scribing auxiliary structure has the following advantages over traditional technology: By coordinating the marking auxiliary template, positioning components, and connecting components, during the marking operation on the asbestos board, the marking auxiliary template is first laid on the surface of the asbestos board. After determining the position of the marking auxiliary template and the asbestos board, force is applied to the knob, causing the threaded cylinder to rotate counterclockwise. The center position of the silicone sheet moves away from the asbestos board, and the cavity formed by the silicone sheet is in a negative pressure state, which can tightly adhere to the surface of the asbestos board, thereby improving the stability between the marking auxiliary template and the asbestos board. This ensures accurate positioning, prevents the marking auxiliary template from sliding or misaligning when positioned on the asbestos board, reduces marking deviation, and ensures marking accuracy.

[0009] In addition, since there are multiple embedded cylinders, users can choose the installation position of the adhesive ring according to the condition of the asbestos board surface. The specific installation process is as follows: first, magnetically attach the adhesive ring and the magnetic ring, and then use bolts to thread the silicone sheet to the convex rod so that the silicone sheet, the convex rod and the embedded cylinder are attached together, thus completing the installation of the positioning component. Because there are a large number of embedded cylinders, the installation position of the positioning component can be selected to facilitate the smooth connection of the positioning component to the asbestos board surface.

[0010] By coordinating the marking auxiliary template, positioning components, and limiting components, during the alignment of the marking auxiliary template with the asbestos board, the required cutting length of the asbestos board is first determined. A support rod is inserted into a through hole near the mark, and a nut is threaded onto the support rod, tightening it against the marking auxiliary template to complete the installation. Then, the marking auxiliary template and the asbestos board are aligned, ensuring the edge of the board is flush. At this point, the distance between the board and the end of the marking auxiliary template is equal to the required cutting length of the asbestos board. Furthermore, by observing the scale value indicated by the dotted line near the through hole (i.e., the scale near the support rod laterally), the subsequent cutting length of the asbestos board can be visually determined. This shortens the alignment time between the template and the asbestos board edge, improves work efficiency, and significantly enhances the practicality of the marking operation.

[0014] 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.

[0015] Please see Figures 1-3This utility model provides a technical solution: an auxiliary structure for cutting and marking lines on asbestos boards, comprising: a marking auxiliary template 1, a positioning component on the surface of the marking auxiliary template 1, the positioning component being connected to the marking auxiliary template 1 via a connecting component, and limiting components at both ends of the surface of the marking auxiliary template 1. The positioning component includes: a retaining ring 2, the retaining ring 2 being located on the surface of the marking auxiliary template 1, a threaded cylinder 5 being threadedly connected to the inner wall of the retaining ring 2, a knob 6 being fixedly connected to the end of the threaded cylinder 5, a protruding rod 4 being rotatably connected to the end of the threaded cylinder 5 away from the knob 6, a silicone sheet 3 being connected to the end of the protruding rod 4 away from the threaded cylinder 5, and the silicone sheet 3 being connected to the marking auxiliary template 1. The connecting component includes: multiple embedded cylinders 7, the multiple embedded cylinders 7 being evenly embedded and fixedly fixed to the surface of the marking auxiliary template 1, a magnetic ring 8 being embedded and fixedly fixed to the end of the embedded cylinder 7 near the retaining ring 2, the magnetic ring 8 being magnetically attracted to the retaining ring 2, and the contact surfaces of the silicone sheet 3 and the embedded cylinder 7 being pressed together.

[0016] In the specific implementation process, it is worth noting that the marking auxiliary template 1 is made of high-strength, wear-resistant, and flexible engineering plastic. This material ensures that the template is not easily damaged during repeated use and can adapt to the unevenness of the asbestos board surface, reducing the problem of poor adhesion to the asbestos board caused by the template being too hard. Its surface is finely polished, smooth and flat, which is conducive to the smooth operation of subsequent marking. At the same time, the template is also engraved with clear scale lines and markings, which makes it convenient for operators to accurately position and mark, improving the accuracy and efficiency of marking. The adhesive ring 2 is made of high-quality stainless steel, which has good corrosion resistance and strength, and can ensure that it will not rust or deform during long-term use, ensuring the accuracy of positioning. The knob 6 is designed with an ergonomic shape and has an anti-slip texture, making it easier and less strenuous for operators to turn the knob 6, and preventing slippage. The threaded connection between the threaded cylinder 5 and the inner wall of the adhesive ring 2 is tight. After special processing, the wear resistance of the threads is enhanced, ensuring that they can maintain good performance even after multiple rotations. In the connection state, the rotating connection between the convex rod 4 and the threaded cylinder 5 adopts a precision bearing, which allows the convex rod 4 to rotate flexibly, reducing friction during rotation and ensuring that the silicone sheet 3 can move smoothly and steadily. The silicone sheet 3 is made of highly elastic and highly absorbent silicone material, which has good flexibility and sealing properties, and can be tightly attached to the surface of the asbestos board to form an effective negative pressure adsorption. At the same time, the silicone sheet 3 also has a certain degree of wear resistance, which can extend its service life. The embedded cylinder 7 is made of hard plastic, which has a certain strength and hardness, and can provide stable support for the magnetic ring 8. It is evenly embedded and fixed on the surface of the marking auxiliary template 1, ensuring the stability and balance of the positioning component installation. The magnetic ring 8 is made of strong magnetic material, which has strong magnetic force and can ensure quick and firm magnetic attraction with the adhesive ring 2. It is not easy to fall off even when subjected to a certain external impact. At the same time, the surface of the magnetic ring 8 is coated, which has good rust prevention properties and extends its service life. The magnetic attraction force between the magnetic ring 8 and the adhesive ring 2 is much greater than the force exerted by the threaded cylinder 5 on the adhesive ring 2.

[0017] Furthermore, a bolt 9 is inserted into the surface of the silicone sheet 3, and the bolt 9 passes through the silicone sheet 3 and is threadedly connected to the protruding rod 4.

[0018] In the specific implementation process, it is worth noting that the bolt 9 is made of high-strength stainless steel, which has good tensile strength and corrosion resistance. It can withstand large external forces without breaking or deforming. Its threaded part is precision machined and has a tight threaded connection with the cam 4, ensuring a firm connection between the silicone sheet 3 and the cam 4. During installation, by rotating the bolt 9, the tightness of the connection between the silicone sheet 3 and the cam 4 can be precisely controlled, which can ensure the stability of the connection and avoid damage to the silicone sheet 3 due to over-tightening. At the same time, the head of the bolt 9 is designed with a suitable size and shape, which makes it convenient for operators to use tools to rotate it.

[0019] Furthermore, the limiting component includes: a pair of plates 10, a pair of support rods 11 fixed to the top of the plates 10, the support rods 11 passing through the through holes 12 through the marking auxiliary template 1, and the support rods 11 being threadedly connected to nuts 13, the nuts 13 being abutted against the marking auxiliary template 1.

[0020] In the specific implementation process, it is worth noting that the mounting plate 10 is made of aluminum alloy, which is lightweight and high-strength, making it easy for operators to install. Its surface is anodized, forming a dense oxide film, which not only improves the corrosion resistance of the mounting plate 10, but also makes its surface smoother and more beautiful. The support rod 11 is made of stainless steel, which has good rigidity and toughness, ensuring that it will not deform or break when subjected to certain external forces. The size of the through hole 12 matches the support rod 11, and it is precision machined to ensure that the support rod 11 can pass through smoothly. At the same time, the outer wall of the support rod 11 fits fully with the inner wall of the through hole 12. The nut 13 is a standard part, and its threaded connection with the support rod 11 is tight and reliable. By rotating the nut 13, the relative position between the mounting plate 10 and the scribing auxiliary template 1 can be precisely controlled, thereby achieving precise calibration of the limit component and providing an accurate length reference for the cutting of asbestos board.

[0021] Working principle: The positioning and fixing principle of the line marking auxiliary template: At the start of the asbestos board marking operation, the marking auxiliary template 1 is first laid on the surface of the asbestos board. After determining the relative position of the marking auxiliary template 1 and the asbestos board, external force is applied to the knob 6. The rotation of the knob 6 drives the threaded cylinder 5 to rotate counterclockwise. The rotation of the threaded cylinder 5 causes the center position of the silicone sheet 3 to move away from the asbestos board. As the center position of the silicone sheet 3 moves, the volume of the cavity formed between the silicone sheet 3 and the surface of the asbestos board gradually increases. According to the principle of atmospheric pressure, the air pressure in the cavity decreases and is in a negative pressure state. This negative pressure state generates a strong suction force, which makes the silicone sheet 3 tightly adhere to the surface of the asbestos board, thereby improving the stability between the marking auxiliary template 1 and the asbestos board. Through this stable fixing method, the marking auxiliary template 1 can be accurately positioned on the asbestos board, effectively preventing the template from sliding and misaligning during the subsequent marking process, reducing marking deviation, ensuring the accuracy of the marking, and providing accurate line reference for the subsequent asbestos board cutting.

[0022] The principle of flexible installation of positioning components: The design of the positioning component fully considers the unevenness or impurities that may exist on the surface of the asbestos board. Since there are multiple embedding cylinders 7, the user can flexibly choose the installation position of the adhesive ring 2 according to the actual condition of the asbestos board surface. First, the adhesive ring 2 is magnetically attracted to the magnetic ring 8 to achieve initial positioning and fixation using magnetic attraction. Then, the silicone sheet 3 is threadedly connected to the protruding rod 4 using bolts 9. Through the tightening action of the threads, the silicone sheet 3 and the protruding rod 4 are tightly fitted together. At the same time, the silicone sheet 3 will also fit into the embedding cylinder 7, thus completing the installation of the positioning component. The setting of multiple embedding cylinders 7 provides a variety of installation options. The user can choose the most suitable installation position of the positioning component according to factors such as the undulations and impurity distribution of the asbestos board surface, ensuring that the positioning component can be smoothly connected to the asbestos board surface, further improving the adaptability and stability of the entire auxiliary structure under different working conditions.

[0023] The principle of precise calibration of limit components: During the positioning calibration of the marking auxiliary template 1 and the asbestos board, the limiting component plays a crucial role. First, the corresponding scale position is determined according to the required cutting length of the asbestos board. Then, the support rod 11 is inserted into the through hole 12 adjacent to the scale. Next, the support rod 11 is threaded together with the nut 13, and the nut 13 is tightened to press against the marking auxiliary template 1, thus completing the installation between the mounting plate 10 and the marking auxiliary template 1. After installation, the marking auxiliary template 1 and the asbestos board are calibrated so that the edge of the mounting plate 10 fits against the edge of the asbestos board. At this time, the distance between the mounting plate 10 and the edge of the asbestos board is... The distance at the end of the marking auxiliary template 1 is exactly equal to the length of the asbestos board to be cut. At the same time, by observing the scale value pointed to by the dotted line near the through hole 12 (i.e., the scale near the horizontal position of the support rod 11), the operator can intuitively and accurately know the length of the asbestos board to be cut. This design can greatly shorten the time for the template to align with the edge of the asbestos board, improve work efficiency, and the operator can quickly and accurately position the marking auxiliary template 1 to the appropriate cutting position without repeated measurement and adjustment. This effectively enhances the practicality of the entire marking operation and provides a strong guarantee for the efficient and accurate cutting of asbestos boards.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
