Abstract
The utility model relates to a bent pipe joint which belongs to a mechanical connecting piece and used for the connection of a machine or a pipe and a pipeline. The bent pipe joint comprises a joint body with an inner channel. The joint body comprises a vertical joint and a transverse joint, and external threads are arranged on the vertical joint and the transverse joint. The bent pipe joint is characterized in that two external threads are arranged on the vertical joint. A screw cap and a silicon rubber O-shaped ring are arranged on the vertical joint. The screw cap is connected to one of the two external threads of the vertical joint, and an inner hole of the screw cap is provided with a chamfer. The silicon rubber O-shaped ring is matched with the chamfer of the inner hole of the screw cap. The utility model is reasonable in structure and design, the machine or the pipe and the pipeline are increasingly pressed with the bent pipe joint during using because the bent pipe joint is provided with the screw cap and the silicon rubber O-shaped ring to result in difficult gas leakage. And meanwhile, the silicon rubber O-shaped ring has good elasticity and can be compressed in the chamfer of the inner hole of the screw cap to prevent gas leakage.
Description
Technical field
The utility model relates to a kind of elbow, and it belongs to mechanical fastener, is used for the connection of machine or pipe, pipeline.
Background technique
Elbow now commonly used comprises the fittings body with internal channel, and this fittings body is made up of vertical joint head and horizontal joint, is provided with outside thread on vertical joint head and horizontal joint, and during use this elbow being linked to each other with pipe, pipeline with machine respectively gets final product.But the elbow 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 elbow 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 elbow comprises the fittings body with internal channel, this fittings body is made up of vertical joint head and horizontal joint, on vertical joint head and horizontal joint, be provided with outside thread, it is characterized in that: described vertical joint head is provided with two place's outside threads, and nut and silicone rubber O type circle be installed on the vertical joint head, nut is connected the vertical joint head wherein on the outside thread at a place, and the endoporus at this nut has a chamfering, the interior Hole chamfering of silicone rubber O type circle and described nut is complementary, and makes the utility model machine or pipe in use thus, pipeline is difficult for gas leakage.
Silicone rubber O type circle described in the utility model is on the vertical joint head between two place's outside threads, 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 mainly is made up of fittings body I, nut 3 and silicone rubber O type circle 2, wherein: fittings body I is made up of vertical joint head 1 and horizontal joint 4, vertical joint head 1 is provided with two place's outside threads 12,13, horizontal joint 4 is provided with place's outside thread 41, and nut 3 and silicone rubber O type circle 2 are installed on vertical joint head 1; Nut 3 is connected vertical joint head 1 wherein on the outside thread 13 at a place, and at the endoporus 31 of this nut 3 chamfering 32 is arranged; Silicone rubber O type circle 2 is complementary with the chamfering 32 of described nut endoporus 31, and described silicone rubber O type circle 2 is on the vertical joint head 1 between two place's outside threads 12,13, and 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 the outside thread 12 of the utility model vertical joint head 1, connect machine, and link to each other with pipe or pipeline by the outside thread 41 on the horizontal joint 4 and to 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.
Claims (3)
1, a kind of elbow, comprise fittings body with internal channel, this fittings body is made up of vertical joint head and horizontal joint, on vertical joint head and horizontal joint, be provided with outside thread, it is characterized in that: described vertical joint head is provided with two place's outside threads, and nut and silicone rubber O type circle are installed on the vertical joint head, and nut is connected the vertical joint head wherein on the outside thread at a place, and the endoporus at this nut has a chamfering, and the interior Hole chamfering of silicone rubber O type circle and described nut is complementary.
2, elbow according to claim 1 is characterized in that: described silicone rubber O type circle is on the vertical joint head between two place's outside threads.
