Abstract

The utility model relates to a joint screw cap which belongs to mechanical fastening pieces and is mainly applied to joints. The joint screw cap includes a screw cap body with inner screw threads. The joint screw cap is characterized in that one end of an inner hole of the screw cap body is provided with a chamfer which is in the range of from 15 DEG to 35 DEG. The utility model is reasonable in structure and design, a machine or a pipe and a pipeline are increasingly pressed with a joint with the joint screw cap to be difficult to leak during using because one end of the inner hole of the screw cap body is provided with the chamfer; and at the same time, because a silicon rubber O-shaped ring with good elasticity is matched with the joint screw cap, the leakage prevention effect is good.

Description

A kind of collar nut
Technical field
The utility model relates to a kind of collar nut, and it belongs to mechanically robust spare, mainly is applicable on the joint.
Background technique
Existing joint in use is very easy to leak, and this mainly is because the structural design of nut is reasonable inadequately.Existing nut comprises the nut body with internal thread, because the endoporus of nut body does not have chamfering, it can only be close to O type circle during use, but thisly is close to or is very easy to cause gas leakage, uses reliable inadequately.
Summary of the invention
The purpose of this utility model is to overcome above shortcomings in the prior art, and a kind of reasonable in design, service-strong collar nut are provided.
The technical scheme in the invention for solving the above technical problem is: this collar nut comprises the nut body with internal thread, it is characterized in that: endoporus one end at described nut body has a chamfering.
The chamfering of nut body endoporus described in the utility model is between 15 °-35 °.
The utility model compared with prior art, have the following advantages and effect: reasonable in design, because endoporus one end at nut body has a chamfering, makes machine or pipe, pipeline in use can press tighter and tighter with having joint of the present utility model, be difficult for gas leakage; Simultaneously, owing to flexible good silicone rubber O type circle cooperates with the utility model, so good leak-proof effect.
Description of drawings
Fig. 1 is that figure is partly cutd open in structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Referring to Fig. 1, collar nut of the present utility model comprises the nut body 1 with internal thread 11, and endoporus 12 1 ends of this nut body 1 have a chamfering α, and this chamfering α is between 15 °-35 °; Be 16 ° in the present embodiment.
The shape of the utility model nut body 1 can be various.
During use, the utility model can be connected on any joint that is complementary.For preventing to leak, a silicone rubber O type circle 2 can be set in that the utility model is other, this silicone rubber O type circle 2 is complementary with the chamfering α of described endoporus 12, in use, machine can with press tighter and tighter with having joint of the present utility model, be difficult for gas leakage; Because the good springiness of silicone rubber O type circle 2 is compressed in the chamfering α of nut body 1, can prevent gas leakage.
