The utility model has simple structure, reduced length, reduced weight and reduced cost, and improves the tightness after being buckled with the rubber tube.
Description
Technical Field
The utility model belongs to the technical field of hydraulic pipeline connection, and particularly relates to an improved core.
Background
The hydraulic pipeline connecting joint generally comprises a sleeve and a core, the sleeve, the core and a rubber pipe are buckled and assembled into a whole during installation, the existing core structure is shown in figure 1, the hydraulic pipeline connecting joint comprises a pipeline joint 1 with an integrated structure and a core body 2 for connecting the sleeve and the rubber pipe, the total length of the pipeline joint 1 and the core body 2 is 72mm, a plurality of annular ribs 3 are uniformly arranged on the outer circle of the core body 2 at intervals, and each annular rib 3 comprises a cylindrical section with the diameter of 1mm and a conical section with the diameter of 4 mm; the core with the structure has the following problems in the process of inserting a rubber pipe for buckling and installing and using:
(1) The length of the core is longer, the material consumption is more, and the cost of the core is higher.
(2) The annular convex edges 3 are arranged at a smaller density, so that the sealing performance between the annular convex edges and the rubber pipe is affected.
(3) The outer circle of the core body 2 close to the pipeline joint 1 is of a smooth structure, and the air in the inner circle of the rubber tube is not discharged after buckling and assembling, so that the sealing effect of the rubber tube and the core is affected.
Disclosure of Invention
In order to solve the defects in the prior art, the utility model provides the improved core which has low cost and good sealing performance and is beneficial to exhausting residual gas in the inner circle of the rubber tube during buckling and assembling.
In order to solve the technical problems, the utility model adopts the following technical scheme: the utility model provides an improved generation core, includes the pipeline of an organic whole structure and connects and be used for the core body of adapter sleeve and rubber tube, and core body excircle even interval is equipped with a plurality of sections annular bead, and pipeline connects and core body's total length is 65mm, and every section annular bead all contains 1 mm's cylindrical segment and 3 mm's circular cone section.
A section of corrugated pipe structure is arranged on the outer circle of the core body close to the pipeline joint.
The corrugated structure comprises a plurality of circular rings which are sequentially arranged along the axis direction of the core body, the width of each circular ring along the axis direction of the core body is 1mm, the outer contour of each circular ring is a convex arc line section along the axis direction of the core body, and the radius of the convex arc line section is 0.8mm.
The maximum diameter of the ring is equal to the diameter of the cylindrical section.
By adopting the technical scheme, the length of the whole core is shortened from 72mm to 65mm, the length is compressed by approximately 10%, the weight is reduced, and the cost of a single core is reduced. The conical section length of a plurality of sections of annular convex edges uniformly arranged at intervals on the outer circle of the core body is reduced from 4mm to 3mm, so that the number of the annular convex edges is increased, and the sealing performance of the annular convex edges and the inner circle of the rubber tube is enhanced.
The corrugated structure is matched with the inner circle of the rubber tube port in a sealing way when being buckled in place, so that the exhaust effect can be achieved, and the sealing performance is improved.
The bellows-like structure comprises the number of rings and the corresponding dimensions, which are arranged correspondingly to the remaining part of the outer circle of the core body.
In conclusion, the utility model has the advantages of simple structure, reduced length, reduced weight and reduced cost, and improves the tightness after being buckled with the rubber tube.

FIG. 2 is a schematic diagram of the structure of the present utility model;
fig. 3 is an enlarged view at a in fig. 2.
Detailed Description
As shown in fig. 2 and 3, an improved core of the present utility model comprises a pipe joint 1 and a core body 2 for connecting a sleeve and a rubber pipe, wherein the outer circle of the core body 2 is uniformly provided with a plurality of annular ribs 3 at intervals, the total length of the pipe joint 1 and the core body 2 is 65mm, and each annular rib 3 comprises a 1mm cylindrical section and a 3mm conical section.
A section of corrugated structure 4 is arranged on the outer circle of the core body 2 adjacent to the pipeline joint 1.
The bellows-like structure 4 includes that a plurality of ring 5 is set gradually along core body 2 axis direction, and every ring 5 is 1mm along the width of core body 2 axis direction, and every ring 5 outline is protruding arc line segment along core body 2 axis direction, and protruding arc line segment's radius is 0.8mm.
The maximum diameter of the ring 5 is equal to the diameter of the cylindrical section.
Because the length of the whole core is shortened from 72mm to 65mm, the length is compressed by nearly 10%, the weight is reduced, and the cost of the single core is reduced. The conical section length of the annular ribs 3 of the sections which are uniformly arranged at intervals on the outer circle of the core body 2 is reduced from 4mm to 3mm, so that the number of the annular ribs 3 is increased, and the sealing performance with the inner circle of the rubber tube is enhanced.
The corrugated structure 4 is matched with the inner circle of the rubber tube port in a sealing way when being buckled in place, so that the exhaust effect can be achieved, and the sealing performance is improved.
The bellows-like structure 4 comprises the number of rings 5 and the corresponding dimensions, which are arranged according to the remaining part of the outer circle of the core body 2.
The utility model and its embodiments have been described above with no limitation, and the actual construction is not limited to the embodiments of the utility model as shown in the drawings. In summary, if one of ordinary skill in the art is informed by this disclosure, a structural manner and an embodiment similar to the technical solution should not be creatively devised without departing from the gist of the present utility model.
