The right positioner scale and the left positioner scale are connected through the fixed measuring structure, and the positioner scale can be firmly fixed, so that the equipment is convenient to disassemble and use. The circular rail handrail opening positioner is described below.

[0032] Referring to Figure 1 , a front view of the circular rail handrail opening positioner is shown. Referring to Figure 2 , a sectional view of the right positioner scale and the left positioner scale of the circular rail handrail opening positioner is shown.

The structure of the circular rail handrail opening positioner is described below in combination with Figures 1 to 8 .

[0033] Referring to Figures 1 to 8 , the application provides a circular rail handrail opening positioner which comprises a positioner, a measuring scale 1 and a horizontal bubble 2. The positioner is sleeved on the rail handrail and can move along the rail handrail and rotate around the rail handrail. Marking points for positioning the rail handrail are arranged on the top and the bottom of the positioner. The marking points on the positioner are marked on the rail handrail, so that the opening position of the rail handrail is positioned. The measuring scale 1 is connected to the positioner. The measuring scale 1 is provided with a horizontal scale for measuring the angle value. The horizontal bubble 2 is arranged on the measuring scale 1. The horizontal bubble 2 is arranged corresponding to the horizontal scale on the measuring scale 1. The included angle between the measuring scale 1 and the horizontal plane can be read through the horizontal scale.

[0034] Preferably, when the rail is connected to the handrail in a vertical manner, the positioner is sleeved on the surface of the rail handrail. The steel ball in the sliding groove moves or rotates on the surface of the rail handrail, so that the positioner and the measuring scale 1 move or rotate with the steel ball. When the horizontal bubble 2 on the measuring scale 1 corresponds to 0° on the horizontal scale, the measuring scale 1, the positioner and the horizontal plane are consistent, and the marking points on the positioner are marked on the rail handrail. The opening is made from the marking position.

[0035] Further, when the rail is connected to the handrail at an angle, the end of the handrail needs to be fixed, and then the positioner is rotated on the surface of the handrail by the steel ball. The horizontal bubble 2 on the measuring scale 1 corresponds to the horizontal scale consistent with the inclination angle of the rail, so that the marking points of the positioner are consistent with the angle of the rail. Then a circle is drawn on the rail handrail along the marking points of the positioner, and the center point of the circle is marked for opening.

[0036] Further, the measuring scale 1 is marked by the following formula:

[0037]

[0038] r: the radius of the circular rail section;

[0039] the number of degrees of the central angle of rotation

[0040] Pi: approximately equal to 3.141;

[0041] The length corresponding to the angle is marked on the horizontal scale, and the calibration of the measurement value is completed, that is, the number of degrees is controlled by controlling the moving distance of the horizontal bubble 2 on the measuring scale 1, so as to improve the accuracy.

[0046] Referring to Figures 1 to 3 , Figure 7 , Figure 8In one specific embodiment of the present application, the inner surface of the positioning left ruler 7 and the positioning right ruler 4 are both provided with a sliding groove, and two or more steel balls are arranged in the sliding groove, the steel balls protrude from the sliding groove and contact the handrail, the end of the positioning right ruler is provided with a first spring 51 and a first anti-skid ball 52 connected with the first spring 51, the first anti-skid ball 52 extends into the sliding groove to limit the movement of the steel ball, and the end of the positioning left ruler is provided with a second spring and a second anti-skid ball connected with the second spring, the second anti-skid ball extends into the sliding groove to limit the movement of the steel ball.

[0047] Preferably, as shown in Figures 1 to 3 、 Figure 7 , the first anti-skid ball 52 is pushed by the first spring 51, so that the first anti-skid ball 52 can extrude the steel ball in the sliding groove of the positioning right ruler 4, achieving the effect of extruding and limiting the steel ball in the sliding groove, and avoiding the steel ball from falling out of the sliding groove.

[0048] Further, as shown in Figure 8 , the second anti-skid ball 82 is pushed by the second spring 81, so that the second anti-skid ball 82 can extrude and limit the steel ball in the sliding groove of the positioning left ruler 7, thereby avoiding the steel ball from falling out of the sliding groove.

[0049] Referring to Figures 1 to 3 , in one specific embodiment of the present application, the convex clamping piece 5 protrudes outward to form a convex block near the side close to the positioning left ruler 7, and the concave clamping piece 8 is provided with a concave groove near the side close to the positioning right ruler 4, and the convex block is clamped in the concave groove.

[0050] Further, as shown in Figures 1 to 3 , the convex block on the convex clamping piece 5 is embedded in the concave groove in the concave clamping piece 8, so that the positioning left ruler 7 can be connected with the positioning right ruler 4 and clamped on the surface of the handrail, and the convex block on the convex clamping piece 5 and the concave groove in the concave clamping piece 8 and their connection mode ensure the convenience of disassembling and using the device.

[0054] like Figures 1 to 8 As shown, the construction process of a circular railing handrail opening positioner 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 clamp to embed the groove in the concave clamp to merge the left positioning ruler and the right positioning ruler into a positioning piece, and then put it on the railing handrail, and use the steel ball in the slide groove to move on the surface of the railing handrail to drive the positioning piece to move. When the railing handrail is set horizontally, the steel ball in the positioning piece moves on the railing handrail, driving 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 railing handrail, and then use the marking points on the positioning piece to mark the positioning of the opening at the top and bottom of the railing handrail. When the railing handrail is set at an inclined angle, use the horizontal bubble to align the inclination angle on the horizontal scale with the corresponding value in the measuring ruler, and then use the marking points to mark the opening position. Before locating the next opening position, measure the distance between the two openings using a length measuring ruler to unify the positions between the two openings.

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

[0057] 1. This invention can meet the demand for precise opening of holes at unconventional angles in 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 normal operation when they are neatly connected. It greatly ensures the convenience of equipment installation and removal, simplifies the original need to control the angle, and optimizes it to control the length, lowering the threshold for equipment use and improving on-site construction accuracy.

[0058] 2. Compare this to the factory-directed demolding of circular handrails with holes. Dedicated molds are expensive, and the angle, spacing, and size of the holes can lead to them being obsolete. With the increasing diversity of handrail designs, short-distance molds are often inadequate, while long-distance molds become scrapped. This invention, by adjusting the size of the measuring plate, can accommodate a wide range of diameters and hole angles, offering high cost-effectiveness and versatility.

[0059] 3. Regarding the production and construction cycle. The processing cycle of special models is long, and if the finished product is damaged on site, it needs to be re-customized, which increases the overall construction cycle. The present invention processes on existing general materials, which allows for quick replacement and accurate positioning.

[0060] 4. Compare construction convenience, accuracy, and cost. The actual operators in construction are frontline workers, whose technical skills vary widely. Effectively reducing the difficulty of tool use will greatly ensure their construction accuracy. High construction accuracy and material utilization will significantly reduce secondary material procurement costs. High construction precision results in better overall quality, achieving excellent results the first time and avoiding secondary maintenance costs.

[0061] The present invention has been described in detail above with reference to the embodiments of the accompanying drawings. A person skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention. The scope of protection of the present invention shall be determined by the scope defined in the appended claims.
