Abstract
The utility model relates to a conical through joint which belongs to a mechanical connector and is used for the connection of machines, pipes or pipelines. The conical through joint comprises a joint body with an interior passage, one end of the joint body is a conical head, the other end of the joint body is a straight head, the conical head end of the joint body is provided with an outside thread for the conical head, and the other end of the joint body is provided with an outside thread for the straight head. The conical through joint is characterized in that an additional outside thread is arranged beside the outside thread for the straight head, and the outside thread is provided with a screw cap, an O-shaped ring of silicon rubber is arranged beside the screw cap, a chamfer angle is arranged inside the screw cap hole in an inverted way, and the O-shaped ring of silicon rubber is matched with the chamfer angle of the screw cap hole. The conical through joint has reasonable structural design, and the arrangement of the screw cap and the O-shaped ring of silicon rubber enables the machine, the pipe or the pipeline to be pressed more and more tighter with the conical through joint in the process of operation without air leakage, and meanwhile, the O-shaped ring of silicon rubber has good elasticity and can be compressed into the chamfer angle of the screw cap hole to prevent air leakage.
Description
Technical field
The utility model relates to a kind of awl straight coupling, and it belongs to mechanical fastener, is used for the connection of machine or pipe pipeline.
Background technique
Awl straight coupling commonly used now comprises the fittings body with internal channel, one end of this fittings body is a conehead, the other end is a straight peen, conehead end at this fittings body is provided with the conehead outside thread, then be provided with the straight peen outside thread at the other end, during use this awl straight coupling linked to each other with pipe, pipeline with machine respectively and gets final product.But the awl straight coupling structural design of this structure is reasonable inadequately, and in use sealability is bad, usually can cause the gas leakage of machine or pipe, pipeline.
Summary of the invention
The purpose of this utility model is to overcome above shortcomings in the prior art, and the awl straight coupling of a kind of reasonable in design, good seal performance is provided.
The technical scheme in the invention for solving the above technical problem is: this awl straight coupling comprises the fittings body with internal channel, one end of this fittings body is a conehead, the other end is a straight peen, conehead end at this fittings body is provided with the conehead outside thread, then be provided with the straight peen outside thread at the other end, it is characterized in that nut being installed other also being provided with on an outside thread and its of described straight peen outside thread, at the other silicone rubber O type circle that is equipped with of this nut, the endoporus of described nut has a chamfering, and the interior Hole chamfering of silicone rubber O type circle and described nut is complementary; Make that thus machine or pipe, pipeline are difficult for gas leakage to the utility model in use.
Silicone rubber O type circle described in the utility model is between outside thread and straight peen outside thread, so that be complementary with the interior Hole chamfering of nut.
Silicone rubber O type circle described in the utility model is compressible in the interior Hole chamfering of nut, and this can prevent the gas leakage of machine or pipe, pipeline in use.
The utility model compared with prior art has the following advantages and effect: reasonable in design, because nut and silicone rubber O type circle are installed, make machine or pipe, pipeline in use can press tighter and tighter with the utility model, and be difficult for gas leakage; Simultaneously, the good springiness of silicone rubber O type circle, compressible in the interior Hole chamfering of nut, prevent gas leakage.
Description of drawings
Fig. 1 is that figure is partly cutd open in structural representation of the present utility model.
Fig. 2 is the matching structure schematic representation of the utility model nut and silicone rubber O type circle.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Referring to Fig. 1-Fig. 2, the utility model comprises the fittings body 4 with internal channel, one end of this fittings body 4 is a conehead, the other end is a straight peen, conehead end at this fittings body 4 is provided with conehead outside thread 14, then be provided with straight peen outside thread 12 at the other end, other also being provided with on an outside thread 13 and its of described straight peen outside thread 12 nut 3 is installed, at these nut 3 other silicone rubber O type circles 2 that are equipped with, the endoporus 31 of described nut 3 has a chamfering 32, and silicone rubber O type circle 2 is complementary with the interior Hole chamfering 32 of this nut 3; In the present embodiment, silicone rubber O type circle 2 is between outside thread 13 and straight peen outside thread 12, and this silicone rubber O type circle 2 is compressible in the interior Hole chamfering 32 of nut 3.
The shape of nut 3 can be various in the present embodiment.
During use, can on conehead outside thread 14 of the present utility model and straight peen outside thread 12, be connected machine, pipe or pipeline respectively and get final product; In use, machine can be pressed tighter and tighter with the utility model, is difficult for gas leakage; Because the good springiness of silicone rubber O type circle 2 is compressed in the interior Hole chamfering 32 of nut 3, prevent gas leakage.
