Abstract
The utility model discloses a straight-through quick connector, which comprises a straight-through connector body and a threaded connection nut in threaded connection with the straight-through connector body; the inside logical chamber that forms of spiro union nut, lead to the chamber and divide into front chamber and back chamber, form 2 seal grooves on the front chamber inner wall, install O type sealing washer in the seal groove. According to the utility model, through the built-in clamping sleeve, quick plug-in mounting can be realized, the operation efficiency is improved, meanwhile, the O-shaped ring is arranged in the front cavity, and after the nylon hose is inserted, poor tightness caused by marks formed by the surface of the hose and the inner teeth of the clamping sleeve can be effectively prevented, and the sealing performance of a product is improved.
Description
Technical Field
The utility model relates to a straight-through quick connector.
Background
The direct quick connector seen by us on the market at present has the following defects: after the nylon hose is inserted, the surface of the nylon hose is provided with internal tooth traces due to the reason of the cutting sleeve, so that the tightness is affected, and the structure is insufficient, so that the applicant proposes further improvement on the basis, and designs a straight-through quick connector so as to meet the requirements of the existing market.
Disclosure of Invention
The utility model aims to overcome the existing defects, and provides the straight-through quick connector which is convenient to connect and improves the sealing performance of products.
In order to solve the technical problems, the utility model provides the following technical scheme:
a direct-connection quick connector is characterized in that: the screw joint comprises a straight joint body and a screw connection nut in threaded connection with the straight joint body; the inside logical chamber that forms of spiro union nut, lead to the chamber and divide into front chamber and back chamber, form 2 seal grooves on the front chamber inner wall, install O type sealing washer in the seal groove.
The utility model is further preferably characterized in that the rear cavity is used for installing a clamping sleeve, and a clamping gap is formed between the clamping sleeve and the inner wall of the rear cavity.
In a further preferred embodiment of the present utility model, a sealing ring is provided at the connection between the threaded connection nut and the straight-through joint body.
Compared with the prior art, the utility model has the following beneficial effects:
the utility model comprises a straight-through joint body and a threaded connection nut in threaded connection with the straight-through joint body; the inside logical chamber that forms of spiro union nut, lead to the chamber and divide into front chamber and back chamber, form 2 seal grooves on the front chamber inner wall, install O type sealing washer in the seal groove. According to the utility model, through the built-in clamping sleeve, quick plug-in mounting can be realized, the operation efficiency is improved, meanwhile, the O-shaped ring is arranged in the front cavity, and after the nylon hose is inserted, poor tightness caused by marks formed by the surface of the hose and the inner teeth of the clamping sleeve can be effectively prevented, and the sealing performance of a product is improved.
Drawings
The accompanying drawings are included to provide a further understanding of the utility model and are incorporated in and constitute a part of this specification, illustrate the utility model and together with the embodiments of the utility model, serve to explain the utility model.
In the drawings:
fig. 1 is a schematic structural view of the present utility model.
Detailed Description
The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present utility model only, and are not intended to limit the present utility model.
As shown in fig. 1, the present utility model discloses a through quick connector, which is characterized in that: comprises a straight-through joint body 1 and a threaded connection nut 2 which is in threaded connection with the straight-through joint body 1; the screw connection nut 2 is internally provided with the clamping sleeve 3, a clamping gap 4 is formed between the clamping sleeve 3 and the inner wall of the screw connection nut 2, a through cavity is formed inside the screw connection nut 2 and is divided into a front cavity 5 and a rear cavity 6, a 2-channel sealing groove 7 is formed on the inner wall of the front cavity 5, the rear cavity 6 is used for installing the clamping sleeve 3, an O-shaped sealing ring 8 is arranged in the sealing groove 7, the connecting part between the screw connection nut 2 and the straight-through joint body is provided with the sealing ring 9, and meanwhile, the O-shaped ring is arranged in the front cavity, so that after a nylon hose is inserted, the sealing performance is improved due to poor sealing performance caused by marks formed by the surface of the hose and the inner teeth of the clamping sleeve.
Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present utility model, and the present utility model is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present utility model has been described in detail with reference to the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
