Abstract
Description
Technical Field
[0001] This utility model relates to the field of building decoration, and in particular to a tool for marking the bevel of stair handrails. Background Technology
[0002] Stair railings are important safety and auxiliary facilities in buildings, primarily used to help people maintain their balance and prevent falls when going up and down stairs. There are many material options for stair railings, with metal tubing being a common choice. Because stairs have an incline, the horizontal and vertical railings of the handrail are usually angled. Therefore, when using metal tubing to fabricate stair railings, the tubing used for the horizontal and vertical railings needs to be beveled to facilitate splicing between the tubing and the posts, as well as between the horizontal and vertical railings.
[0003] In large-scale projects, specialized equipment is typically used to uniformly process the beveling of pipes and crossbeams. However, in smaller projects, such as self-built houses or replacing damaged handrails, the cost of using specialized equipment is very high. Therefore, in such cases, construction workers usually rely on experience to process the beveling on the pipes using angle grinders or other cutting tools. However, this method is prone to processing failures, and a failed beveling on one pipe can render the entire pipe unusable, resulting in material waste and delays in the construction schedule. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a stair handrail bevel marking tool.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model discloses a stair handrail bevel marking tool, comprising a pipe, characterized in that two rows of identical marking groups are symmetrically arranged on the side wall of the pipe, each row of marking groups including multiple marking grooves corresponding to different bevel angles, and each marking groove penetrates the side wall of the pipe.
[0006] As a preferred technical solution of this utility model, an angle mark is provided on the outer wall of the pipe between every two beveled grooves of the same angle, so as to find the corresponding bevel groove during use.
[0007] As a preferred embodiment of the present invention, each row of the marking groups includes at least two marking slots.
[0008] As a preferred embodiment of this utility model, the slope difference between the angle marks corresponding to two adjacent marking grooves is 0.5°.
[0009] As a preferred embodiment of this utility model, the pipe is a stainless steel pipe, and its inner diameter is adapted to the outer diameter of the handrail vertical pipe to be marked.
[0010] A stair railing bevel marking assembly includes multiple bevel marking tools for pipes with different inner diameters, a cap, and a sleeve with an open end. The inner diameter of the sleeve is adapted to the outer diameter of the bevel marking tool for the pipe with the largest inner diameter, so that multiple bevel marking tools can be inserted into the sleeve from the opening. The cap is installed at the opening of the sleeve.
[0011] As a preferred embodiment of this utility model, a rubber ring is provided on the inner wall of the cylinder cover, and the rubber ring is adapted to the outer diameter of the sleeve so that the cylinder cover is installed at the opening of the sleeve.

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0016] In the attached diagram, all identical reference numerals refer to the same components.
[0017] Example 1: like Figure 1 , 2 As shown in Figure 6, this utility model provides a stair handrail bevel marking tool, including a pipe 2. The pipe 2 is characterized in that two rows of identical marking groups 3 are symmetrically arranged on its side wall. Each row of marking groups 3 includes multiple marking grooves 4 that correspond to different bevel angles and are arranged at intervals. Each marking groove 4 penetrates the side wall of the pipe 2.
[0018] Furthermore, each row of marker groups 3 contains at least two marker slots 4.
[0019] Furthermore, pipe 2 is a stainless steel pipe, and its inner diameter is compatible with the outer diameter of the handrail vertical pipe to be marked.
[0020] Specifically, the inner diameter of the marking tool tube 2 is matched with the outer diameter of the handrail vertical tube (post or railing) to be cut, that is, after the handrail vertical tube is inserted into the tube 2, there is no obvious gap between the two.
[0021] In use, first, the slope of the handrail surface tube is measured, i.e., the slope of the staircase where the handrail is to be installed is measured. Then, the angle between the handrail vertical tube and the handrail surface tube is calculated based on the measured slope. According to this angle, the corresponding marking groove 4 is found on the tube 2. The marking line required for cutting is marked on the handrail vertical tube by passing a marker through the marking groove 4. Then, the handrail vertical tube is pulled out from the tube 2. Finally, the handrail vertical tube is cut and ground along the above marking line with an angle grinder or other cutting tools to obtain a bevel that matches the slope of the handrail surface tube, thus facilitating the installation of the handrail vertical tube.
[0022] Example 2: like Figure 1 , 2 As shown in Figures 6 and 7, an angle mark 5 is provided on the outer wall of the pipe 2 between every two bevel marking grooves 4 with the same angle, so that the marking groove 4 with the corresponding slope can be found during use.
[0023] Specifically, the angle marked by angle mark 5 is the same as the angle between the handrail surface tube and the handrail vertical tube, and is marked next to the corresponding angle mark slot 4, so that workers can quickly find the corresponding mark slot 4 according to the angle mark 5, thereby improving work efficiency; In another option, the angle marked by angle mark 5 can also be the same as the slope when the handrail face tube is installed. This can save the process of calculating the angle between the handrail face tube and the handrail vertical tube. Workers can directly find the corresponding bevel cutting angle of the handrail vertical tube by the slope of the handrail face tube, thereby further improving work efficiency.
[0024] Furthermore, the slope difference between the angle marks 5 corresponding to the two adjacent marking slots 4 is 0.5°.
[0025] Specifically, the slope of stairs is usually within 45°, and the slope change is usually within 0.5°. Therefore, the bevel angle corresponding to the marking groove 4 is changed by 0.5°, and the angle mark 5 is also increased by 0.5°, so that a bevel marking tool can adapt to the bevel marking needs of handrail vertical pipes of the same diameter with multiple slopes.
[0026] In another option, the dimensions of the applicable handrail riser are marked on the outer wall of pipe 2.
[0027] In another scheme, if the handrail vertical tube is a round tube, then tube 2 is a round tube, and the mark made through the marking groove 4 is an arc; if the handrail vertical tube is a square tube, then tube 2 is a square tube, and the mark made through the marking groove 4 is a straight line; if the handrail vertical tube is a tube of other shapes, then tube 2 is a tube type that is compatible with the handrail vertical tube.
[0028] Example 3: like Figure 3-5 As shown, a stair handrail bevel marking assembly includes multiple bevel marking tools 1 with different inner diameters of pipes 2, a sleeve cap 6, and a sleeve 7 with one end open. The inner diameter of the sleeve 7 is adapted to the outer diameter of the bevel marking tool 1 with the largest inner diameter of the pipe 2, so that multiple bevel marking tools 1 can be inserted into the sleeve 7 from the opening. The sleeve cap 6 is installed at the opening of the sleeve 7.
[0029] Specifically, handrail risers typically come in various diameters, generally between 19-60mm in diameter or side length. Handrail risers are usually divided into two types: posts and railings, and these two types may also have different diameters. Therefore, workers need to carry multiple beveling marking tools, which is inconvenient to carry individually. Therefore, multiple beveling marking tools are placed into the sleeve 7 in descending order of pipe diameter. After placement, the sleeve cap 6 is placed over the opening of the sleeve 7, thus forming a beveling marking tool set, making it easier for workers to carry and use. The sleeve 7 is adapted to the pipe shape of the pipe 2 so as to facilitate the insertion of the beveling marking tool.
[0030] Furthermore, a rubber ring 8 is provided on the inner wall of the sleeve 6, and the rubber ring 8 is adapted to the outer diameter of the sleeve 7 so that the sleeve 6 is installed at the opening of the sleeve 7.
[0031] Specifically, the cap 6 is secured to the opening of the sleeve 7 by a rubber ring 8 to prevent the bevel marking tool from falling off.
[0032] Furthermore, the openings of the sleeve 6 and the sleeve 7 are connected by threads.
[0033] Specifically, the cap 6 is fixed to the opening of the sleeve 7 by a threaded connection to prevent the bevel marking tool from falling off.
[0034] like Figure 3-4 As shown, the top of the cap 6 has a handle, which makes it easy for workers to hold the bevel marking assembly tool.
[0035] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
