Abstract

The utility model relates to a wire tube fitting for a building electrician, wherein the wire tube fitting not only can be connected with a wire sleeve tube but also can be used for sealing the opening of the wire sleeve tube. The wire tube fitting is composed of two components. Specifically, one component is characterized in that a screw thread is distributed on the outer cylindrical surface of one end based on the direct connection joint of the existing wire sleeve tube on the market; and the other component is a cap shaped sealing component matched with the screw thread. The two components are screwed together by the screw thread; and in other words, the component with one end, having the outer screw thread, of the wire sleeve tube direct connection joint and the sealing component are in internal screw thread connection. One opening end of the wire sleeve tube is connected with a wire sleeve tube needing opening sealing in a socket joint mode by the glue and thus the sealing of the wire sleeve tube is realized, thereby preventing the cast-in-place concrete from entering the leading-out end port, exposed out of the casting surface, of the wire sleeve tube. When the sealed wire sleeve tube needs to be connected, only the cap-shaped sealing component is needed to be twisted off at the negative direction, wherein the sealing component can be recycled; and the sealed wire sleeve tube is in socket joint connection with another wire sleeve tube by the glue.

Description

The electric wire pipe fitting

[technical field] the utility model relates to a kind of building electrician and uses the electric wire pipe fitting, can prevent that especially cast-in-place concrete from entering the cable conduct that exposes casting area and drawing port, makes pre-buried cable conduct can run through electric wire smoothly.

[background technology] is present, known application prevent that cast-in-place concrete from entering cable conduct and drawing the method for port and be: 1. adhesive tape twines and seals the cable conduct that exposes concrete cast face and draw port; 2. draw port with the flat cable conduct that exposes concrete cast face of pliers folder.

Method shortcoming 1. is: tape seal does not reach certain number of plies, and namely the number of plies is few, and the concrete that adhesive tape can be poured into a mould punctures, and concrete will enter in the cable conduct and result in blockage like this; And the number of plies increase of tape seal will make the use amount of adhesive tape increase, and uses adhesive tape later not reuse, and will cause the waste of material like this.

Method shortcoming 2. is: improved labour intensity, wasted material.

Two kinds of common shortcomings of method: the one, the pre-buried cable conduct of requirement is drawn port and is exposed concrete cast face and surpass 10cm (generally reserving about 20cm), is convenient to press from both sides the sealing operation of rectangular wire sleeve pipe and prevents that tape seal is tight and piled up high cast-in-place concrete and enter and result in blockage in the cable conduct; The 2nd, before the wall of laying bricks, cut short the cable conduct that sealed before the cast concrete, avoid building a wall and being broken apart by chopping by the brick cutter because harming brickwork, make and enter the blockage that foreign material cause equally in the pipe, therefore need seal again.So the operation of these two kinds of methods all can cause the waste of manpower and material.

[summary of the invention] for improve existing the pre-buried cable conduct exit that exposes concrete cast face seal efficient, reduce material and cost of labor and avoid stopping up the situation of cable conduct, the utility model provides a kind of electric wire pipe fitting, and this kind electric wire pipe fitting has the cable conduct of connection and effectively seals the function that cable conduct is drawn port.This kind electric wire pipe fitting seal that part can reuse and simple to operate.

The technical scheme that its technical problem that solves [technical scheme] the utility model adopts is: the utility model comprises two parts, the one, on the basis of the direct-connected joint of the used cable conduct of existing market, with the part of screw thread on the one end outer cylindrical surface cloth, the one and the lid shape of this screw thread pairing seal part.Above-mentioned two parts are twisted and are closed, and namely an end of the direct-connected joint of cable conduct has externally threaded part and seals the part internal thread and be connected, and its opening one end is connected to finish with the glue socket joint with the cable conduct that need seal and seals.In the time need being connected with another wire sleeve pipe by the cable conduct that sealed, only need turn on and cover shape and seal part (can recycle), overlap effective glue socket joint with another wire and be connected.

[beneficial effect] the utility model has following beneficial effect:

1. seal tight.What the utility model adopted is the mode of screw thread combination, and two parts can tight fully combining.

2. be difficult for destroyed.Adopt the utility model that pre-buried cable conduct is drawn port and seal, that its height that exposes concrete cast face can be reduced to is disconnected by bumping to be difficult for, do not influence the brickwork operation, conveniently turn on and cover shape to seal part be 1 centimetre to 2 centimetres of principle.And draw port after reducing height, saved before the wall of laying bricks cutting short and sealing operation again cable conduct.

3. simple to operate, save manpower.When using the utility model, only need that lid shape is sealed part and aim at the threaded end of the direct-connected joint of cable conduct, manually swivelling cover shape is sealed part, closes until twisting fully with the direct-connected joint of cable conduct; Behind cast concrete, only need opposite spin lid shape to seal part, the direct-connected joint of itself and cable conduct is separated, insert wire sleeve pipe connection again and get final product.

4. reusable edible is saved material.Lid shape of the present utility model is sealed part behind cast concrete, when need connecting cable conduct, can intactly will cover shape and seal part and take off, and can not influence use next time.

[description of drawings] further specifies the utility model below in conjunction with accompanying drawing and enforcement:
