Abstract
The utility model provides a pipeline through-wall connecting and fixing device. The pipeline through-wall connecting and fixing device comprises a pair of cage nuts 1 and 5 and a pipe joint 4, the cage nuts 1 and 5 enable a pipeline 6 to be connected to the two ends of the pipe joint 4 through external threads on the two ends of the pipe joint 4, a torque bearing body 7 integrated with the pipe joint is arranged nearby one end of the pipe joint 4, and a fastening nut 3 is arranged on the external thread at the other end of the pipe joint 4. The pipeline through-wall connecting and fixing device is simple and practical, installation processes are simplified, labor intensity is reduced, sealants are not used, and the braking pipeline can be checked and maintained conveniently.
Description
Technical field
The utility model relates to a kind of pipeline to be worn wall and is connected and fixed device, belongs to mechanical erection technical field.
Background technique
The line arrangement of some systems on city rail vehicle (for example braking system) spreads all over car and gets on the bus down.For a good comfortable environment is by bus provided to passenger, pipeline is worn to the sealing that wall enters guest room and proposed very high requirement, to reach good guest room sound insulation, the effect of protecting such as dustproof, moistureproof.Existing technological scheme is generally to adopt wearing the mode that adds sleeve pipe on wall pipeline.This need to be connected on a Socket welding larger than pipeline diameter on car body, and pipeline is from passing through in the middle of sleeve pipe, after installing, at sleeve pipe and wear filling with sealant between wall pipeline.Mounting process trouble, solder joint impact is attractive in appearance, after injection sealer, is not easy to maintenance.
Model utility content
The purpose of this utility model overcomes the deficiency of above-mentioned prior art exactly, provides a kind of pipeline to wear wall and is connected and fixed device.
The purpose of this utility model is achieved in that a kind of pipeline wears wall and be connected and fixed device, comprise a pair of clasp type nut and a union body, clamped nut is connected to pipeline respectively the two ends of union body by the outside thread on union body two ends, it is characterized in that near a termination, being provided with on union body the cubold that is subject to union body one, on the other end outside thread, tightening nut is set.
Scheme of the present utility model, simple and practical, simplify mounting process, reduce labor intensity, do not use sealer, can to braking line, carry out Inspection and maintenance easily.
Accompanying drawing explanation
Fig. 1 is that the utility model embodiment's pipeline is worn wall and is connected and fixed principle of device schematic diagram.
In figure, be labeled as: 1-clasp type nut, 2-wall, 3-nut, 4-union body, 5-clasp type nut, 6-pipeline, 7-is subject to square hexahedron.
Embodiment
For making the utility model embodiment's object, technological scheme and advantage clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
Referring to Fig. 1, the pipeline of the present embodiment is worn wall and is connected and fixed device, comprises a pair of clasp type nut 1,5, and a union body 4.On union body 4, near a termination, be provided with union body one be subject to square hexahedron 7, tightening nut 3 is set on the other end outside thread.Clamped nut 1,5 is connected to pipeline 6 respectively the two ends of union body 4 by the outside thread on union body 4 two ends.During installation, can set the length that union body 4 tightens screw thread one end according to the thickness of wall 2.To being subject to square hexahedron direction fastening nut 3, device is fixedly clamped on wall 2, simultaneously by the hole sealing on wall 2.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technological scheme that still can record aforementioned each embodiment is modified, or part technical characteristics is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment's technological scheme of the utility model.
