Problems solved by technology
[0003] However, when this crimp nut is used in a high-pressure environment, there may be leakage of the medium from the end of the connecting pipe and the outer shoulder, and there is usually no special seal between the outer shoulder and the inner shoulder of the crimp nut Therefore, the leaked medium is easy to leak from the inner shoulder of the buckle nut and the outer shoulder of the pipe fitting, posing risks and potential safety hazards

Embodiment Construction
[0021] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .
[0022] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

The invention discloses a buckling and pressing nut and a pipe fitting matched with the same. The buckling and pressing nut is provided with a front end face, an inner thread, a rear end face and an inner shoulder used for abutting against the pipe fitting; a tool withdrawal groove is formed between the inner shoulder and the inner thread, and the inner circumference face of the inner shoulder comprises an abutting-against section and an inclined section; the surface of the abutting-against section is parallel with the central axis of the inner thread, an included angle is formed between the surface of the inclined section and the central axis of the inner thread, and the inclined section is located between a parallel section and the inner thread; and the risk of leakage of a medium between the inner shoulder of the buckling and pressing nut and an outer shoulder of the pipe fitting can be reduced.
Description
technical field [0001] The invention relates to a buckle nut and a pipe fitting, in particular to a pipe fitting matched with the buckle nut. Background technique [0002] Nut connection is a kind of fastener that is very commonly used in pipelines. Generally, the connection end of pipe fittings will be made into the form of an outer shoulder, and the inside of the nut can be made into an inner shoulder to facilitate the tightening of the nut. During the connection process, the locking nut realizes sealing by being threadedly connected with the connecting pipe at the other end, so that the end of the connecting pipe touches against the outer shoulder. [0003] However, when this crimp nut is used in a high-pressure environment, there may be leakage of the medium from the end of the connecting pipe and the outer shoulder, and there is usually no special seal between the outer shoulder and the inner shoulder of the crimp nut Therefore, the leaked medium is easy to leak from b...
