Abstract
The utility model discloses a connecting apparatus for a fastening and inserting type line, which is used for laying electric appliance circuits in a building. The utility model is mainly characterized in that a fastening and inserting type line (1) which is made by a thin wall drawing steel tube is provided with a concave groove (2), a fastening external connection sleeve (3) which is combined with the fastening and inserting type line is provided with a squeezing fastening groove (4), and a connecting apparatus is composed of the concave groove and the squeezing fastening groove. Under construction, by means of external force, the concave groove and the squeezing fastening groove can be well combined for fixedly connecting the line. The utility model which is especially suitable for a high building has the advantages of convenient operation, convenience, safety, and reliability, saves 63.3 % steel, and reduces cost by 18 %-20 %.
Description
The utility model relates to a kind of as laying the button plug formula spool coupling arrangement that electric appliance circuits is used in the building.
Now building generally adopt plastic flexible pipe or the rigidity spool formed by malleable iron casting connector and running water pipe as the pre-embedded pipe of laying electric appliance circuits in it.The defective of doing existence like this is: 1, use plastic flexible pipe as spool except also installing additional in addition the grounding wire, can't satisfy the requirement that building on the high-rise building design must adopt the rigidity spool.2, because existing rigidity spool adopts thread connection, spool need carry out screw thread and welding processing in laying, especially the pipeline join operation is quite difficult, not only dangerous but also inconvenient when the enterprising line pipe of high-rise building is laid, and the big cost height of pipeline overall weight.
The purpose of this utility model is to avoid above-mentioned defective or not enough and a kind of novel rigidity spool is provided, and promptly replaces water pipe and malleable iron connector with thin-wall steel tube and external cover, with the simple button plug formula spool coupling arrangement that connects alternative thread connection of withholding.
The utility model is achieved in that coupling arrangement is made up of spool and external cover, is provided with Baltimore groove and becomes button plug spool on spool, and external putting is provided with the extruding draw-in groove and becomes and withhold external cover.
Button plug spool draws steel pipe manufacturing with thin-walled part.Withhold the external extruding draw-in groove that puts with respect to the Baltimore groove setting on the button plug spool, and form when mounted.
The utility model compared with prior art, rolled steel dosage reduces 63.3%, cost decline 18-20% does not especially adopt thread connection, has saved screw thread and welding processing operation.When pipeline need connect, only need put two junction button plug spools in withholding among the external cover, by means of external force, form the extruding draw-in groove withholding external putting with respect to button plug spool Baltimore groove place, spool and external cover are just fixing thus.This kind connecting mode is simple to operate, connects reliably, particularly more shows its convenient, safe and reliable superiority when high-rise building is laid spool.The utility model is to accelerating construction progress, guarantees safety in production and saves the steel very practical meaning that reduced cost significantly.
Accompanying drawing is the utility model structural representation.
Below in conjunction with accompanying drawing the utility model most preferred embodiment is further described: draw steel pipe as buckleing plug spool (1) with thin-walled part, be processed with Baltimore groove (2) thereon.Withholding the plug spool of buckleing that external cover (3) will connect is placed in one, when mixing up fixed-site, only need by external force, as adopt the instrument of crush inhury and so on, on the external position that puts with respect to button plug spool Baltimore groove, be squeezed into extruding draw-in groove (4), the extruding draw-in groove combines with Baltimore groove, makes button plug spool and withhold external cover to be connected and fixed, and withholding external cover can be straight tube-like or elbow shape.
Claims (5)
1, a kind of button plug formula spool coupling arrangement is made up of spool and external cover, it is characterized in that spool is provided with Baltimore groove (2) and becomes and withhold spool (1), and external putting is provided with extruding draw-in groove (4) and becomes and withhold external cover (3).
2, coupling arrangement according to claim 1, the extruding draw-in groove that it is characterized in that withholding on the external cover (3) is provided with corresponding to the Baltimore groove of buckleing on the plug spool (1) (2).
3, coupling arrangement according to claim 1, it is characterized in that withholding external cover (3) is straight tube-like.
4, coupling arrangement according to claim 1, it is characterized in that withholding external cover (3) is the elbow shape.
5, coupling arrangement according to claim 1 is characterized in that button plug spool (1) draws steel pipe manufacturing with thin-walled.
