Detailed Description
The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When a component is considered to be "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present, as well as being disposed not only in an intermediate position but also in both ends as far as they are within the scope defined by the intermediate position. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items
As shown in fig. 2 to 4, the present utility model provides a tubing bender with bellows. Since the bellows is soft and has a plastic protective skin that is easily broken by impact, in the embodiment of the present application, the pipe bender includes a bending portion 100, and a bending groove 200 is formed on the bending portion 100. When the bellows is fitted into the bending groove 200, the bellows is bent into a shape corresponding to the bending groove 200.
Because the meter has the corrugated pipe DN15, the outer diameter is 23mm, when the width W of the bending groove 200 is too large, a handheld mode is adopted, and the gap between the meter has the corrugated pipe and the bending groove 200 is too large, so that the meter has the corrugated pipe and is not easy to limit. When the width W of the bending groove 200 is too small, the gauge bellows cannot limit the gauge bellows, and the protective skin of the gauge bellows is worn. For this reason, in the embodiment of the present application, the width W of the bending groove 200 is 20 to 30mm, and the depth D of the bending groove 200 is 10 to 15mm. Preferably, the width W of the bending groove 200 is 25mm, and the depth D of the bending groove 200 is 13mm.
Referring to fig. 2 to 4, specifically, in the embodiment of the present application, the bending groove 200 includes a straight pipe section 210 and a bent pipe section 220, the straight pipe section 210 is connected to the bent pipe section 220, and an end of the straight pipe section 210 connected to the bent pipe is tangential to the bent pipe section 220. Since the outer diameter of the meter bellows is 23mm, the minimum bending radius of the meter bellows is 30mm when the meter bellows is installed, and for this reason, the radius R of the curved pipe section 220 is 30-45 mm. Preferably, the radius R of the bend section 220 is 35mm.
Because the meter bellows is a stainless steel bellows, rebound occurs when the meter bellows is bent, and when R < 5D, the playback angle is 5-8 degrees, and the central angle theta of the bent pipe section 220 cannot be set to 90 degrees. For this purpose, the central angle θ of the bend section 220 is set to 90 ° to 100 ° in some embodiments of the present application. Preferably, the angle of the bend section 220 is set at 98 °.
Referring to fig. 1, since the total length of the gauge bellows is 20cm, and the joints are arranged at the two ends of the gauge bellows, the length error of the gauge bellows can be considered to be qualified within 1.5cm in consideration of the on-site adjustable deviation. Since the minimum bending radius of the corrugated pipe is 30mm, according to the circumference formula of a circle: c=2×pi×r,2x3.14×30×1/4=47.1 mm. The meter has a bellows end straight tube section 210 of about 76.5mm. For this purpose, in some embodiments of the present application, the length L of the straight tube segment 210 is set to 55 to 72.5mm. Preferably, since the radius R of the bent pipe section 220 is preferably 35mm, the length L of the straight pipe section 210 is set to 65mm, and 65 is less than 7.25, and the straight pipe section 210 does not affect the installation of the gauge bellows.
In some embodiments of the present application, the measuring part 300 is further included, the measuring part 300 is provided with graduations, and the measuring part 300 is disposed on the side wall of the bending part 100. Specifically, the measuring section 300 is 0 to 150mm. The measuring part 300 is connected to the bending part 100 by nails and/or glue. The bending part 100 may be made of common wood, and the measuring part 300 may be made of a steel rule.
The pipe bender for the corrugated pipe of the watch solves the problems that the bending error of the stainless steel corrugated pipe of the watch hanging is large and repeated bending is needed, can bend the corrugated pipe into 90 degrees at one time, has attractive appearance, accords with related specifications, and ensures that the corrugated pipe is accurately, accurately and safely installed. The labor cost is saved, the possible leakage points in the room are reduced, and the risk coefficient is reduced.
