Description
Technical Field
The utility model belongs to the technical field of the electrician's sleeve pipe, concretely relates to electrician's sleeve pipe return bend spring.
Background
PVC-U is used as a main material in an electrical casing, in the construction of the electrical casing, a spring with a corresponding size is usually selected to bend the electrical casing, but in the use process, the bending pipe usually causes the pipe to wrinkle and break; in addition to the above, some water electrician/finishing companies pursue the aesthetic property of the construction site, and there are cases where there are multiple 90 ° bends in succession for an electrical conduit; such construction can not be avoided in practice, mainly because many constructions now all adopt the condition of ground fluting, when needs lay by ground to preceding spool when laying the spool, just need carry out two continuous bendings to the spool just can satisfy actual construction demand.
However, in the existing use situation, due to the limitation of the used spring, a plurality of water electricians mostly only have one upper wall bend during construction, and then adopt a direct connection mode of bending one bend and connecting the middle when two bends are needed, so that great inconvenience is generated in actual construction.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned problem that exists among the prior art, the utility model aims to provide a can buckle twice, and can prevent at the in-process of buckling that wrinkling appears in tubular product and break, the electrician's sleeve pipe return bend spring of installation of being convenient for.
The utility model provides a following technical scheme: the electrician sleeve pipe elbow spring is characterized by comprising an electrician sleeve pipe, a spring and a pull wire, wherein the spring comprises a spring main body and hook rings arranged at two ends of the spring main body;
the spring main part includes middle part structure and the narrow end structure that is located middle part structure both sides, the external diameter of narrow end structure outwards reduces gradually along middle part structure one side, shackle fixed mounting is in the outer end of narrow end structure.
The electrical casing elbow spring is characterized in that the outer diameter of the middle structure is 15.60-17.00mm, the spring main body is of a steel bar structure, the thickness of a steel bar is 1.00-1.50mm, and the width of the steel bar is 2.50-3.50 mm.
The electrical casing pipe elbow spring is characterized in that the spring main body is prepared by square tempering of round steel wires.
The electrical casing elbow spring is characterized in that the spring main body is quenched at high temperature, and the surface of the spring main body is subjected to electroplating or electrophoresis treatment.
The electrical casing elbow spring is characterized in that the electrical casing is one of transparent or opaque.
Through adopting above-mentioned technique, compare with prior art, the beneficial effects of the utility model are as follows:
1) the utility model optimizes the spring coefficient of the spring main body by optimizing the technical parameters such as the thickness and the width of the steel bar of the spring main body based on the size standard requirement of the pipe, and avoids the situations that the pipe is crinkled and broken in the bending process of the electrical sleeve because of the elasticity of the internal spring; the pipe can be continuously bent twice, so that the operation requirement of on-site pipeline laying is met;
2) the utility model discloses the both sides of well spring main part are provided with the narrow end structure and install the structural shackle of narrow end, utilize the gradual change structure of narrow end structure external diameter, through pull wire and annular hook, can be convenient pack into the spring main part and pull out electrician's sleeve pipe.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments of the specification. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
On the contrary, the invention is intended to cover alternatives, modifications, equivalents and alternatives which may be included within the spirit and scope of the invention as defined by the appended claims. Furthermore, in order to provide a better understanding of the present invention to the public, certain specific details are set forth in the following detailed description of the invention. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details.
Referring to fig. 1, an electrical casing elbow spring includes an electrical casing 1, a spring, and a pull wire 3, wherein the electrical casing 1 may be made of a transparent material or an opaque material; the spring comprises a spring body 2 and hook rings 4 at two ends of the spring body 2;
