Abstract
The utility model discloses a straight-through type electric melting pipe fitting, which belongs to the field of plastic pipe fittings and comprises a sleeve and two electrode holders arranged on the outer ring of the sleeve, wherein electric heating wires are arranged at two ends of the inner wall of the sleeve, a wiring terminal is fixedly arranged in the electrode holders, the wiring terminal is electrically connected with the electric heating wires, a limiting step is arranged between the two sections of electric heating wires in the sleeve, and the electrode holders are arranged at the limiting step. When the electric melting pipe fitting is used for connection, the end part of the pipe fitting inserted in the electric melting pipe fitting directly abuts against the end face of the limiting step, so that the pipe wall of the electric melting pipe fitting at the electrode seat is not directly contacted with other pipe fittings. The limiting step can not only increase the wall thickness around the electrode seat, but also avoid the situation that the part is connected into a weak strength area, thereby greatly prolonging the service life of the pipe fitting.
Description
Technical Field
The utility model relates to the field of plastic pipe fittings, in particular to a straight-through type electric melting pipe fitting.
Background
The polyethylene electrofusion tube has one or more combined heating elements that effect fusion of the electrofusion tube to the tube or tube spigot end by converting electrical energy to thermal energy. Resistance wires are respectively distributed at two ends of the tube body of the electric melting tube, and after the electric melting tube is electrified, the resistance wires heat to melt part of plastics at two ends of the electric melting tube so as to realize butt joint of the butt joint tube matched with the electric melting tube. The electrode position of the existing straight-through type electric smelting pipe fitting is closer to the straight-through inner wall, and is a weak strength area in the process of connecting other pipelines due to the fact that the electrode position is closer to the inner wall, and the pipe fitting is scrapped due to the fact that stress is cracked.
Disclosure of Invention
The utility model aims to provide a straight-through type electric melting pipe fitting.
The technical scheme of the utility model is as follows: the utility model provides a straight-through type electric smelting pipe fitting, includes the sleeve, sets up two electrode holders at the sleeve outer lane, and telescopic inner wall both ends all are equipped with the electric heating wire, and electrode holder internal fixation is provided with binding post, binding post and electric heating wire electric connection are located and are provided with spacing step between two sections electric heating wires in the sleeve, and the electrode holder setting is in spacing step department.
According to a further technical scheme, the thickness of the limiting step is smaller than that of the sleeve.
According to a further technical scheme, the electric heating wires are spirally distributed along the inner wall of the sleeve.
According to a further technical scheme, the limiting steps are made of glass fiber reinforced polypropylene.
According to a further technical scheme, a reinforcing rib is arranged between the electrode base and the outer wall of the cylinder body.
The utility model has the beneficial effects that:
according to the utility model, the existing structure is improved, the limiting step is arranged at the center of the electric melting pipe fitting, and the position of the electrode seat is moved from the connecting end to the position. When the utility model is used for connection, the end part of the pipe fitting inserted in the utility model directly abuts against the end surface of the limit step, so that the pipe wall of the electric melting pipe fitting positioned at the electrode seat is not directly contacted with other pipe fittings. The limiting step can not only increase the wall thickness around the electrode seat, but also avoid the situation that the part is connected into a weak strength area, thereby greatly prolonging the service life of the pipe fitting.
Drawings
Figure 1 is a schematic diagram of the structure of the present utility model,
the electrode holder comprises a sleeve, an electrode holder body, a reinforcing rib, an electric heating wire, a connecting terminal, a limiting step and a limiting step, wherein the sleeve is arranged at the bottom of the electrode holder body, the electrode holder body is arranged at the bottom of the electrode holder body, and the reinforcing rib is arranged at the bottom of the electrode holder body.
Detailed Description
The utility model will be further illustrated by the following non-limiting examples, which illustrate the utility model.
As shown in fig. 1, the utility model provides a straight-through type electric melting pipe fitting, which comprises a sleeve 1 and two electrode holders 2 arranged on the outer ring of the sleeve 1, wherein reinforcing ribs 3 are arranged between the electrode holders 2 and the outer wall of a cylinder body. The electric heating wires 4 are arranged at two ends of the inner wall of the sleeve 1, and the electric heating wires 4 are spirally distributed along the inner wall of the sleeve 1. The electrode holder 2 internal fixation is provided with binding post 5, binding post 5 and electric heater strip 4 electric connection, is provided with spacing step 6 between two sections electric heater strips 4 in the sleeve 1, and electrode holder 2 sets up in spacing step 6 department, and spacing step 6 thickness is less than sleeve 1's thickness, and spacing step 6's material is glass fiber reinforced polypropylene, has temperature resistance, withstand voltage, bending resistance good characteristics.
When the utility model is used for connection, the end part of the pipe fitting inserted in the utility model directly abuts against the end surface of the limit step 6, so that the pipe wall of the electric melting pipe fitting positioned at the electrode seat 2 is not directly contacted with other pipe fittings.
In summary, the limiting step 6 can not only increase the wall thickness around the electrode holder 2, but also avoid the weak strength area around the electrode holder 2 due to connection, thereby greatly increasing the service life of the pipe fitting.
The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
