Abstract
The utility model provides a pair of slightly thick big radian elbow in constant diameter or middle section belongs to the technical problem of electrician's sleeve pipe field, solution: when current electric wire passes greater curvature pipe fitting middle section, because pipe fitting middle section space is narrow and small, easily with wire card in the pipe fitting middle section, the technical scheme who adopts: including two bell and spigots, two bell and spigots pass through the pipe fitting middle section to be connected, the pipe fitting middle section is including connecting the segmental arc, and the both ends of connecting the segmental arc all are provided with the changeover portion, and connect the segmental arc and pass through the changeover portion and be connected with two bell and spigots, the changeover portion forms with bell and spigot coincidence part and hinders into ring, connect the internal diameter of segmental arc and internal diameter and the external diameter that the external diameter was more than or equal to the bell and spigot.
Description
Technical field
The utility model belongs to electrical casing pipe field, particularly relates to a kind of isometrical or large radian elbow that stage casing is slightly thick.
Background technology
At present, in the pipe fitting market of PVC electrical casing pipe and zinc-plated irony sleeve pipe, there is a kind of full name to be the pipe fitting of large radian 90 degree of elbows, be called for short curved greatly.Common model is the models such as 16 types, 20 types, 25 types, and the bell and spigot internal diameter at two is 16mm, 20mm, 25mm respectively.
As shown in Figure 1 and Figure 2, curved greatly at present fitting structure is made up of three parts: 1, two bell and spigots 2, two hinder the pipe fitting stage casing into ring (the step-like circle protrusion stoping the electrical casing pipe inserted to insert to stage casing further) 3, arc.Existing large curved architectural feature is: hinder and be directly connected with the crooked radian of pipe fitting stage casing along stage casing into ring, owing to hindering into a ring internal diameter circle less of bell and spigot internal diameter, so cause a whole stage casing also circle more young than socket joint.External presentation is: two bell and spigots are thick, and stage casing is thin.
Usually, when electric wire penetrates from electrical casing pipe and extracts out (more needing during Change electric wire to extract out), the resistance that the pipe fitting stage casing namely curved greatly in the corner of spool is subject to is maximum.Because current big syphon part stage casing is comparatively thin, cause pipe fitting stage casing will strengthen further the frictional resistance that electric wire produces, even inside electrical wire fastener in the tube section.In this case firmly withdrawing electric wire, is also easy to the plastic insulation cortex scratching electric wire, produces the hidden danger of Electrical Safety.
Utility model content
The utility model overcomes the deficiency that prior art exists, when solving existing electric wire through big syphon part stage casing, easily by the problem of electrical wire fastener section in the tube, aim to provide a kind of isometrical or large radian elbow that stage casing is slightly thick, this bend design novel structure, by increasing internal diameter and the external diameter in pipe fitting stage casing, increases the spatial accommodation in pipe fitting stage casing, thus reduce the frictional resistance in electric wire and pipe fitting stage casing, reduce the situation of damage wire insulation line cortex.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of isometrical or large radian elbow that stage casing is slightly thick, comprise two bell and spigots, two bell and spigots are connected by pipe fitting stage casing, described pipe fitting stage casing comprises connection segmental arc, and the two ends connecting segmental arc are provided with changeover portion, connects segmental arc and is connected with two bell and spigots by changeover portion, described changeover portion and bell and spigot intersection are formed and hinder into ring, and the internal diameter of described connection segmental arc is more than or equal to the internal diameter of bell and spigot.
Preferably, described changeover portion is straightway, or is arc.
Preferably, the external diameter of described connection segmental arc is more than or equal to the external diameter of bell and spigot.
Preferably, the material of large radian elbow is PVC, or is galvanized iron material.
Preferably, the angle in described pipe fitting stage casing is 90 degree, or is 45 degree, or is 22.5 degree.
The utility model compared with prior art has following beneficial effect: by respectively increasing a changeover portion at two ends, original pipe fitting stage casing, namely ring is entered in the resistance that one end of changeover portion connects internal diameter smaller, the other end connects the larger pipe fitting stage casing of internal diameter, described changeover portion plays reducing effect, thus increase internal diameter and the external diameter in pipe fitting stage casing, make its internal diameter being more than or equal to bell and spigot and external diameter, meanwhile, smooth structure in changeover portion ensure that the frictional force to the electric wire penetrated wherein produces reduces greatly, and the easy smoothness of electric wire is passed.After the internal diameter of pipe fitting connection segmental arc and external diameter increase, just add the spatial accommodation in pipe fitting stage casing, thus greatly reduce the frictional resistance in electric wire and pipe fitting stage casing, reduce the situation of damage wire insulation cortex, make electricity consumption safer.When also making electric wire penetrate in electrical casing pipe and pass in addition, more fast smooth, improve the installation effectiveness of water and electricity worker.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Fig. 1 is existing main TV structure schematic diagram curved greatly.
Fig. 2 is the side-looking structural representation of Fig. 1.
Fig. 3 is structural representation of the present utility model
In figure: 1 is bell and spigot, 2 for hindering into ring, and 3 is pipe fitting stage casing, and 4 is changeover portion, and 5 for connecting segmental arc.
Embodiment
As shown in Figure 3, a kind of isometrical or large radian elbow that stage casing is slightly thick, comprise two bell and spigots 1, two bell and spigots 1 are connected by pipe fitting stage casing 3, pipe fitting stage casing 3 comprises and connects segmental arc 5, the two ends connecting segmental arc 5 are provided with changeover portion 4, one end of changeover portion 4 be connected segmental arc 5 and connect, the other end is connected in bell and spigot 1, changeover portion 4 and bell and spigot 1 intersection are formed and hinder into ring 2, the internal diameter connecting segmental arc 5 is more than or equal to the internal diameter of bell and spigot 1, and whole large radian elbow adopts integral forming process to make.
Changeover portion 4 makes resistance enter ring 2 and be connected segmental arc 5 and seamlessly transit, and is convenient to electric wire smoothness and passes, and the internal diameter connecting segmental arc 5 increases, and greatly reduces electric wire and the frictional resistance in pipe fitting stage casing 3, decreases the situation damaging wire insulation cortex.
More specifically changeover portion 4 is straightway or is arc.According to the internal diameter size connecting segmental arc 5, select the degree of crook of changeover portion 4.In order to make more smooth the passing of electric wire, so make the external diameter of connection segmental arc 5 be more than or equal to the external diameter of bell and spigot 1.
In addition, the material of the large radian elbow in actual production process is PVC, or is galvanized iron material.Be applicable to PVC electrical casing pipe and zinc-plated irony electrical casing pipe respectively.Equally, can needing by the angle design in pipe fitting stage casing 3 for being 90 degree according to actual production, or be 45 degree, or be 22.5 degree.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from the utility model aim.
