Abstract
The utility model discloses an oil pipe conical button head, which is characterized in that the end of a joint is provided with two circles of mutually parallel circular grooves and the lower part of the circular groove is provided with a spring fastener. The end of a clamping sleeve is provided with a convex ring outwards. Compared with the prior art, the utility model has the advantage of high installation speed. The assembling efficiency of the assembly line can be effectively improved, and the organizational design of the spring fastener effectively improves the sealing properties and safety of products. The joint is difficult to be disengaged from the clamping sleeve caused by the vibration.
Description
Technical field:
The utility model relates to the technical field of car air conditioner accessory, a kind of specifically oil pipe taper heading, particularly its mechanical connecting structure.
Background technique:
The port of traditional oil pipe heading is generally tubulose, and the port bottom is provided with position limit cycle, and mainly there is following shortcoming in the oil pipe heading of this spline structure: need weld when 1, heading is connected with pipeline, therefore cause efficiency of assembling not high; 2, existing oil pipe heading and pipeline welding back sealing is not high, causes the seepage phenomenon easily.
Summary of the invention:
The purpose of this utility model is to provide a kind of oil pipe taper heading, and it is low that it can overcome the existing product efficiency of assembling, shortcomings such as poor sealing performance.
To achieve these goals, technological scheme of the present invention is: a kind of oil pipe taper heading, and it mainly wraps rammer pier nose body, it is characterized in that: the port of described heading body is provided with chamfering, and the heading body place of port bottom is provided with spacing seal ring.
The utility model discloses a kind of oil pipe taper heading, the port of its heading body is provided with chamfering, and the heading body place of port bottom is provided with spacing seal ring, and its advantage is: 1, easy for installation, assembling speed is fast, can effectively improve the assembling speed of product; 2, after assembling was finished, the sealing of heading and pipeline was fine, can effectively prevent the seepage phenomenon.
Description of drawings:
Fig. 1 is existing oil pipe heading structural representation
Fig. 2 is the utility model structural representation
Embodiment:
With reference to the accompanying drawings, the utility model further is described
The utility model is a kind of oil pipe taper heading, it mainly comprises pier nose body 1, it is different from prior art and is: the port of described heading body is provided with chamfering 2, the heading body place of port bottom is provided with spacing seal ring 3, the angle of chamfering can be spent between 55 degree 15, and spacing seal ring socket also is fixed on heading body place, with being integral of heading body structure, spacing seal ring place is provided with chamfering 4, and the angle of its chamfering is spent between 55 degree 15.
In the specific implementation, the chamfering of heading body port is 35 degree, an other pipeline is docked in the heading body, because the chamfering structure of heading body port, make pipeline be easy to just be socketed in heading body place, the pipeline that moves downward runs into the spacing seal ring at heading body place, because it also has a chamfering structure, the angle of its chamfering is 40 degree, because spacing seal ring upper part diameter is less than the diameter of pipeline, the diameter of spacing seal ring bottom is enforced pipeline downwards greater than the diameter of pipeline, pipeline will firmly be stuck in spacing seal ring place, plays effect fixing and sealing.
