Abstract
The utility model discloses a multi-pass anti-explosion threading box convenient to replace. The threading box comprises a box body, wherein the box body is uniformly divided into an upper box body and a lower box body, a plurality of tube holes and fixation lugs are formed on the lateral wall of the box body, the uniformly dividing line of the upper box body and the lower box body passes through the centers of the tube holes and the fixation lugs. In the case of being not power off, the damaged connection box is quickly replaced.
Description
Technical field
The utility model relates to a kind of electric wire protective device, specifically relates to a kind of how logical explosion-proof PULL BOX of being convenient to change.
Background technology
In cable winding displacement, installation and the maintenance process of production scene, the connection PULL BOX of the electric wire anti-explosion fire shielded-plate tube that adopts mostly is monolithic construction, and electric wire passes its inner chamber.For safety anti-explosive, PULL BOX must be changed after damaging immediately, but problem is above-mentioned PULL BOX, and to need that when changing electric wire is withdrawn into the position that is replaced the line box from terminal just replaceable, so namely delayed the time, wasted great amount of manpower again, simultaneously also influenced production, and do not allowed the equipment of intermittent operation to change at some, this just exists more dangerous hidden danger.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the purpose of this utility model provides a kind of how logical explosion-proof PULL BOX of being convenient to change, and it just can promptly change the terminal box of damaging under the situation of not cutting off the power supply.
To achieve these goals, the technical solution adopted in the utility model is: a kind of how logical explosion-proof PULL BOX of being convenient to change, comprise box body, described box body is made of the upper cartridge body of dividing equally and lower box body, offer a plurality of insertion holes and fixing ear at the sidewall of box body, the equal separated time of its upper cartridge body and lower box body runs through insertion hole and the fixing center of ear.
Preferably, the inwall of described insertion hole is provided with internal thread.
Preferably, offer screw hole on the described fixedly ear.
Compared with prior art, the utility model has the advantages that: this PULL BOX can just can promptly change the terminal box of damaging under the situation of not cutting off the power supply.The utility model is simple in structure, and is convenient to use, saves labor, and is the desirable device of the fire-proof and explosion-proof facility of electric wire, can adapt in the fire-proof and explosion-proof facility of electric wire of various occasions.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Among the figure: 1, upper cartridge body 1; 2, lower box body 2; 3, insertion hole; 4, fixing ear; 5, equal separated time; 41, screw hole.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1 and Fig. 2, the how logical explosion-proof PULL BOX of being convenient to change of the present utility model, comprise box body, described box body is made of the upper cartridge body of dividing equally 1 and lower box body 2, offer a plurality of insertion holes 3 and fixing ear 4 at the sidewall of box body, the equal separated time 5 of its upper cartridge body 1 and lower box body 2 runs through insertion hole 3 and the fixing center of ear 4.The inwall of described insertion hole 3 is provided with internal thread.Offer screw hole 41 on the described fixedly ear 4.
In the use, when checking circuit, only need turn on the screw on the fixing ear 4, take off upper cartridge body 1 and get final product.Change PULL BOX as needs, just upper cartridge body 1 and lower box body 2 are taken down, the PULL BOX that renews is buckled in new upper cartridge body 1 and lower box body 2 on the electric wire, and the screw of tightening on the fixing ear 4 gets final product, very convenient fast, save labor.Certainly, concrete installation or replacing can select the explosion-proof PULL BOX of two logical, threeway, four-way to install or change as required, specifically just do not give unnecessary details at this.
Above-mentioned only is a kind of embodiment of the present utility model, not in order to limiting the utility model, all any modifications of doing within spirit of the present utility model and principle, is equal to and replaces and improvement etc., all should be included within the protection range of the present utility model.
