Abstract
The invention relates to a rivet-based augmented product, in particular to a rivet capable of connecting a gas-liquid delivery pipe. The invention has the technical scheme that the rivet comprises a barrel body and is characterized in that one end of the barrel body is provided with a convex ring, and the other end thereof is provided with a tubular joint; and a rivet barrel is arranged between the convex ring and the tubular joint of the barrel body. The invention has the advantages that according to the design with the speed rivet idea, the riveting is fast without rejected rivets, and the energy saving and the environmental protection can be realized; the riveting is firm, the sealing property is good, and the defects of the leakage of the 'tubular joint', thread loosening and the like can be overcome; the cost is lowered, and the raw materials can be saved by about 50% compared with the traditional 'straight tubular joint'; the riveting can be realized reversely, and gas or liquid can flow in after the riveting; moreover, according to the design in a form of the 'tubular joint', the rivet has convenient connection, so as to be suitable for the automobile industry, the electromechanical industry and the like.
Description
Technical field
The present invention relates to a kind of extension product, specifically a kind of rivet that connects gas-liquid delivery pipe based on rivet.
Background technique
At present, self-plugging rivet has been widely used in the riveted joint of metal and nonmetallic plane or non-planar junction member.
For widening the new approaches of research and development product, explore the new route of rivet field products innovation, make full use of the technical advantage that my company makes rivet, development promptly has the novel product that the riveted joint function embodies other product functions again, thereby make riveting technology apply to other field, really reach efficient, energy-saving and environmental protection.
Summary of the invention
The purpose of this invention is to provide a kind of riveted joint firmly, good seal performance, anti-leak, and can replace pipe joint, particularly can ventilate after the riveted joint body or liquid especially are fit to the rivet of the connected gas-liquid delivery pipe of auto parts machinery riveted joint.
According to technological scheme provided by the invention, the described rivet that connects gas-liquid delivery pipe comprises cylindrical shell, it is characterized in that: an end of described cylindrical shell is provided with bulge loop, and the other end is provided with tubular configured joint; Be the nail tube between the bulge loop of described cylindrical shell and the tubular configured joint.
Be provided with the through hole of perforation in the described cylindrical shell.
The external diameter of described bulge loop is greater than the external diameter of nail tube, and the length of bulge loop is less than the length of nail tube.
Described tubular configured joint comprises the conical section that is positioned at the end and type conical bench section near cylindrical shell.
The end diameter of described conical section is less than the diameter of an end of close type conical bench section.
There is multistage step on the surface of described type conical bench section, and described step dwindles gradually from an end to the end near the nail tube near conical section.
The length of described tubular configured joint is less than the length of nail tube.
External tracheae of described tubular configured joint or liquid line.
Advantage of the present invention is:
1, press the design of quick rivet theory, riveted joint is given up and is followed closely energy-conserving and environment-protective fast;
2, riveted joint firmly, good seal performance, and solved the defectives such as leakage, thread looseness of former " pipe joint ";
3, fall end cost, compare, save material about 50% with traditional " free flow coupling ";
4, can reversely rivet, can ventilate or liquid after the riveted joint;
5, by the design of " pipe joint " form, easy to connect.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present invention.
Fig. 2 is a sectional drawing of the present invention.
Fig. 3 is that the present invention rivets preceding schematic representation.
Fig. 4 is that the present invention rivets the back schematic representation.
Embodiment
The invention will be further described below in conjunction with concrete accompanying drawing.
As shown in Figure 1: can connect the rivet of gas-liquid delivery pipe, comprise cylindrical shell, be provided with the through hole 4 of perforation in the described cylindrical shell; One end of cylindrical shell is provided with bulge loop 2; The other end is provided with tubular configured joint 3; Be nail tube 1 between the bulge loop 2 of described cylindrical shell and the tubular configured joint 3.The external diameter of described bulge loop 2 is greater than the external diameter of nail tube 1, and the length of bulge loop 2 is less than the length of nail tube 1.
The length of described tubular configured joint 3 is less than the length of nail tube 1.Described tubular configured joint 3 comprises the conical section that is positioned at the end and type conical bench section near cylindrical shell.The end diameter of described conical section is less than the diameter of an end of close type conical bench section, so that cover trachea or liquid line.There is multistage step on the surface of described type conical bench section, and described step is from dwindling gradually near an end of conical section to the end near nail tube 1, after tracheae or liquid line are socketed on the tubular configured joint 3, utilizes described step tracheae or liquid line can be fixed.The setting of the conical section of tubular configured joint 3 and type conical bench section makes tracheae or liquid line easy to connect, firm, and good airproof performance.
During use, by pull bar 7 under the effect of riveting gun power, bulge loop 2 expands fastening in by the endoporus of riveted joint workpiece 6, nail tube 1 and tubular configured joint 3 are stayed on the outer wall of riveted joint workpiece 6, and protrude outer wall, so that tubular configured joint 3 connects tracheae or liquid line, but through hole 4 transport gas or liquid, solved defectives such as original " pipe joint " leakage, thread looseness, and riveted joint firmly, good airproof performance.
