Abstract
The utility model discloses an improved safety indicating device in electric smelting of pipe fitting. The device comprises a pipe fitting body, a limiting control ring, an indicating nail and a resistance wire, wherein at least one pair of fixed strips extends out of the pipe fitting body, and the fixed strips are connected with the upper end of the indicating nail; the lower parts of the fixed strips and the pipe fitting body form a cavity, and the cavity is filled with hot melt adhesive. After the improved safety indicating device is heated, the indicating nail can rise up in a vertical direction; after heating is finished, the hot melt adhesive can fully fill the cavity in the indicating nail position and gets solidified so that a pipe fitting is not heated through easily; and after heating, the indicating nail is completely fused together with a key body through the hot melt adhesive.
Description
Technical field
The utility model relates to plastic pipe field, particularly a kind of modified model electric melting pipe fittings safety indicating device.
Background technique
The construction of engineering plastics pipe, uses capacitance technology conventionally, and its principle is by Resistant heating, the connected pipeline outer wall of inwall of plastic pipe to be at high temperature fused together, thereby forms an entirety.By the development of technology and the consideration of construction safety aspect, existing electric melting pipe fittings is all provided with indicating device in its main pipe body, this indicating device is in main pipe body, to install an instruction nail, be provided with a peep hole outward in main pipe body corresponding to instruction nail, in the heating process of pipe fitting, also constantly rise along with the plastics of main pipe body the inside constantly melt instruction nail, workmen indicates the rising of nail to judge the work of welding by observation.The advantage of this technology is that construction safety, weld bond simple and pipe fitting are attractive in appearance, and workman only need carry an electric melting welder and can construct, and this welding method efficiency of construction is high, power consumption is conducive to environmental protection less and very.But pipe fitting is heated inhomogeneous often, this just causes heating rear instruction nail is not vertical lifting, but toward predominate, this just can not play indicative function, and the surrounding of instruction nail is hollow out, therefore instruction nail is thinner than other positions around, easy boiling hot wearing after heating.
Model utility content
(1) technical problem that will solve
The purpose of this utility model will overcome above-mentioned shortcoming exactly, aims to provide a kind of modified model electric melting pipe fittings safety indicating device.
(2) technological scheme
For achieving the above object, modified model electric melting pipe fittings safety indicating device of the present utility model, comprises pipe fitting body, spacing control loop, instruction nail, resistance wire, and described pipe fitting body extends at least a pair of fixed strip, and described fixed strip is connected with the upper end of instruction nail; Described fixed strip below forms cavity with pipe fitting body, fills hot melt adhesive in this cavity.
Further, described instruction nails on end for taper, and lower end is cylindrical.
Further, described spacing control loop is that inverted cone and its mouth diameters are less than the cylindrical diameter in instruction nail lower end.
Further, described instruction nail and pipe fitting body are identical material.
Further, the top of described instruction nail is no more than spacing control loop upper surface.
(3) beneficial effect
Compared with prior art, the technical solution of the utility model has the following advantages: modified model electric melting pipe fittings safety indicating device of the present utility model, after being heated, instruction nail can keep Vertical direction to rise, after heating completes, hot melt adhesive can be filled the cavity of instruction nail position completely, solidify, make pipe fitting be difficult for scalding and wear, and after heating, instruction nail fuses with crucial body completely by hot melt adhesive.
Brief description of the drawings
Fig. 1 is modified model electric melting pipe fittings agent structure schematic diagram of the present utility model;
Fig. 2 is the structural representation at the instruction nail position of the utility model modified model electric melting pipe fittings indicating device;
Fig. 3 is the structural representation at instruction nail position after the heating of the utility model modified model electric melting pipe fittings indicating device.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1 to Figure 3, the utility model modified model electric melting pipe fittings safety indicating device, comprise pipe fitting body 1, spacing control loop 2, instruction nail 3, resistance wire 4, described pipe fitting body 1 extends at least a pair of fixed strip 5, and described fixed strip 5 is connected with the upper end of instruction nail 3; Described fixed strip 5 belows and pipe fitting body 1 form cavity, fill hot melt adhesive 6 in this cavity.It is taper that 3 upper ends are followed closely in described instruction, lower end is cylindrical, and described spacing control loop 2 is that inverted cone and its mouth diameters are less than the instruction nail 3 cylindrical diameters in lower end, in the time of 3 rising of instruction nail, spacing control loop 2 can the most effectively be blocked in the position of a fixed value instruction nail 3, stops it to continue to rise.
Described instruction nail 3 and pipe fitting body 1 are identical material, make instruction nail 3 and crucial body 1 have identical fusing point and setting temperature, are therefore not easy to produce gap.
Under heated condition not, the top of instruction nail 3 is no more than spacing control loop 2 upper surfaces.
When after pipe heating, instruction nail 3 can slowly rise, and ensures that with instruction nail 3 fixed strips that are connected 5 instruction nail 3 also keeps the trend of vertical lifting the non-uniform temperature in the situation that, and meanwhile, hot melt adhesive 6 is melted and expanded, and can fill up in instruction nail 3 space around.
The instruction nail that the utility model has overcome the electric melting pipe fittings safety indicating device of prior art is heated can not keep the defect of vertical lifting trend after inequality, in the space around instruction nail, fill hot melt adhesive simultaneously, after heating, can effectively space be filled up, overcome below, space pipe fitting thinner, easily scalded the defect of wearing.
In sum, above-mentioned mode of execution is not restricted mode of execution of the present utility model, and the modification that all those skilled in the art carry out on the basis of flesh and blood of the present utility model or equivalent deformation, all at technology category of the present utility model.
