[0035] Furthermore, when the railing is connected to the handrail at an angle, the end of the handrail needs to be fixed, and then the positioning piece is rotated on the surface of the handrail using a steel ball so that the horizontal bubble 2 on the measuring ruler 1 corresponds to the horizontal scale consistent with the inclination angle of the railing, so that the marking point of the positioning piece is consistent with the angle of the railing, and then a circle is drawn on the railing handrail along the marking point of the positioning piece, and the hole is marked with the center point of the circle.

[0036] Furthermore, the measuring ruler 1 is divided into scales by the following formula;

[0037]

[0038] r: cross-sectional radius of circular railing section;

[0039] The required rotation angle

[0040] Π: approximately equal to 3.141;

[0054] like Figures 1 to 8 As shown, the construction process of a circular railing handrail hole locator of the present invention is described below.

[0055] First, embed the connecting spine on the first connecting piece into the left ruler slot, and use the protrusion on the convex clamping piece to embed into the groove in the concave clamping piece, so that the left positioning ruler and the right positioning ruler are combined to form a positioning piece, which is then put on the handrail, and the steel ball in the slide groove is used to move on the surface of the handrail to drive the positioning piece to move. When the handrail is set horizontally, the steel ball in the positioning piece is moved on the handrail to drive the positioning piece and the measuring ruler to rotate, so that the horizontal bubble on the positioning piece corresponds to 0° on the horizontal scale, so that the positioning piece and the measuring ruler are consistent with the horizontal plane of the handrail, and then the marking points on the positioning piece are used to mark the positioning of the opening at the top and bottom of the handrail. When the handrail is set at an inclined angle, the horizontal bubble is used to align the inclination angle on the horizontal scale in the measuring ruler, and then the marking points are used to mark the positioning of the opening. Before locating the next opening position, the interval is measured by using a ruler for measuring length to unify the positions of the two openings.

[0056] The beneficial effects of the circular handrail opening positioner of the present invention are:

[0057] 1. This invention can meet the needs of precise opening of holes at unconventional angles for circular cross-section handrails. By adopting concave and convex clips, it not only ensures the stability of the components when they are partially separated, but also ensures the normal operation when they are arranged and connected, which greatly ensures the convenience of equipment installation and disassembly. It simplifies the original angle control and optimizes it to control the length, lowers the threshold for equipment use, and improves the accuracy of on-site construction.

[0058] 2. Compare and choose the factory to directly demould and process the circular cross-section handrail with holes. The special model is expensive, and the opening angle, spacing, and size will lead to the model being no longer used. With the diversified design of the handrail, it is not worthwhile to open the mold for a short distance, and the long distance mold model is scrapped. The present invention can meet the needs of various diameters and opening angles by adjusting the size of the measuring disk, with high cost performance and strong versatility.

[0059] 3. Regarding the production and processing cycle and construction cycle. The processing cycle of the special model is long, and the finished product is damaged on site and needs to be re-customized, and the overall construction cycle is long. The present invention is processed on the existing general materials, with fast replacement and accurate positioning.

[0060] 4. Compare the construction convenience, accuracy and cost. The actual operators in the construction are front-line workers, whose technical capabilities vary greatly. Effectively reducing the difficulty of using tools will greatly ensure the construction accuracy of front-line workers. The construction accuracy is high, the material utilization rate is high, and the secondary procurement cost of materials will be greatly reduced. The construction accuracy is high, the overall quality presentation effect is better, and the first-time achievement avoids the secondary maintenance costs.

[0061] The present invention is described in detail above in conjunction with the embodiments of the accompanying drawings. A person skilled in the art can make various variations of the present invention according to the above description.
