Abstract
A plastic expansion type connecting and fixing device for pipes belongs to reinforcing parts of non-metallic materials and consists of an inner tube and an outer sleeve. The outer wall surface of the inner tube and the inner wall surface of the outer sleeve are both inclined in a bevel form, and the inner tube is pulled by means of tightening screws so that the outer sleeve is compressed to expand. The overall plastic expansion type connecting and fixing device for pipes is fixed in a pipe and can be connected with external bolts through embedded nuts. Without welding or glue adhesion, the plastic expansion type connecting and fixing device for pipes can be fixed in the pipe and can be connected with the external bolts through the embedded nuts.
Description
Technical field
The utility model belongs to the reinforcer of nonmetallic material, and especially a kind of plastic expansion formula tubing is connected and fixed device.
Background technique
Traditional tubing needs to adopt welding or glue bonding way as if being fixed on certain object, or welds set screw nut or bolt in pipe, and connecting by outside bolt or nut could be fastening again.Adopt these traditional modes to connect tubular goods, waste time and energy, and when tubular goods needs frequent conversion tie point, very dumb.
Summary of the invention
The utility model is in order to overcome the deficiency of traditional tubing Placement, to provide a kind of being convenient to be fixed in the pipe, and the device that can be connected with the external world.
The technological scheme that its technical problem that solves the utility model adopts is: constitute a plastic expansion formula tubing by two parts and be connected and fixed device, one of them parts is outer sleeves, and another parts are inner cores.The outer sleeve outside is cylindric, and wherein an end has flange, and the other end has a plurality of openings, and opening part is stressed can be expanded outwardly, and the outer sleeve internal face is conical surface, and the inwall next door has two the stepped circular holes that can lay fastening screw trip bolt.The inner tank theca face is conical surface, and the outer wall symmetry has two guiding projections, and the inner core monnolithic case is the band ear water tumbler shape of putting upside down; The inner core internal fixation is equipped with built-in nut, is used for being connected with outer bolt.The outer sleeve internal face is identical with the tapering of inner tank theca face, and inner core is less than outer sleeve, and inner core is placed in the outer sleeve, and inner tank theca face and outer sleeve internal face are close to.Two parts are put into pipe, tighten screw, the pull inner core makes its compressing outer sleeve, and outer sleeve contacts closely with tube wall after expanding, thereby is fixed in the pipe, can be connected with outer bolt by built-in nut, reaches the effect of tubing connector.

Fig. 5 is inner core A-A section and outer sleeve C-C section assembling design sketch.
Wherein: 1, inner core, 2, outer sleeve, 3, projection, 4, built-in nut, 5, flange, 6, circular hole, 7, screw.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described, referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5.
Plastic expansion formula tubing is connected and fixed device to be made up of inner core 1 and outer sleeve 2, and outer sleeve 2 internal faces are conical surface, and inner core 1 outer wall is conical surface, and outer sleeve 2 internal faces are identical with the tapering of inner core 1 outer wall.Outer sleeve 2 outsides are cylindric, and wherein there is flange 5 upper end, and there are a plurality of openings the lower end, and opening part is stressed can be expanded outwardly, and outer sleeve 2 inwalls next door is provided with two the stepped circular holes 6 that can lay fastening screw trip bolt.Inner core 1 outer side surface symmetry has two guiding projections 3, and inner core 1 monnolithic case is the band ear water tumbler shape of putting upside down, and internal fixation is equipped with built-in nut 4, is used for being connected with outer bolt.Inner core 1 is less than outer sleeve 2, and inner core 1 is placed in the outer sleeve 2, and inner core 1 outer wall and outer sleeve 2 internal faces are close to.Two parts are put into pipe, tighten up screw 7, make inner core 1 compressing outer sleeve 2 make its expansion, contact closely with tube wall after outer sleeve 2 expands, thereby be fixed in the pipe, can be connected with outer bolt by built-in nut 4.
Claims (2)
1. a plastic expansion formula tubing is connected and fixed device, comprises an outer sleeve and an inner core, it is characterized in that: the outer sleeve internal face is conical surface, and the inner tank theca face is conical surface, and the outer sleeve internal face is identical with the tapering of inner tank theca face.
2. plastic expansion formula tubing according to claim 1 is connected and fixed device, it is characterized in that: outer sleeve one end has flange, and the other end has a plurality of openings, and the inner core internal fixation is equipped with nut.
