Abstract
The utility model discloses a connection type mine shaft pipeline direct connecting buckle, belonging to the field of industrial mining, and mainly aiming at solving the problems in the aspects such as connector safety, airtightness, connectivity and the like of the traditional pipeline at present. The connection type mine shaft pipeline direct connecting buckle structurally comprises a male buckle and a female buckle, wherein the end of the male buckle is provided with a ring-shaped extension part, and a buttress external thread is formed in the revolution surface at the outer side of the ring-shaped extension part; the end of the ring-shaped extension part is provided with a ring-shaped sealing bulge; the outer diameter of the ring-shaped extension part is not equal to that of a base body of the male buckle; the end surface at the tail end of the base body of the male buckle is a sealed step surface; a buttress internal thread is formed in the inner cylindrical surface of the end of the female buckle; a ring-shaped groove is formed at the position where the buttress internal thread arranged at the end of the female buckle is connected with a base body of the female buckle; the inner diameter of the male buckle is equal to that of the female buckle. The connection type mine shaft pipeline direct connecting buckle is simple in structure, convenient to operate and convenient in pipeline connection, and is capable of improving the working condition at a pipeline connector while meeting the airtightness, so that connector breakage is avoided; the connection type mine shaft pipeline direct connecting buckle is simple in structure, low in manufacturing cost and wide in applicability.
Description
Technical field
The utility model relates to the direct-connected button of connected type mine pipeline, belongs to industrial and mineral exploitation field.
Background technique
Carry conventionally and adopt for liquid, gaseous state now: body two threading, then connect with tapped joint, or employing welding manner.On-the-spot need more complicated professional tool successfully to dock using, so and because there is joint to increase the resistance of material in pipe, be in use subject to many limitations.Aspect connectivity and sealing, exist tensile force low, sealing does not easily cause by force the phenomenons such as body leakage and sealing-off fracture.
Model utility content
The problem that the utility model exists for current traditional delivery pipe body joint, has designed the direct-connected button of connected type mine pipeline.
The technical scheme in the invention for solving the technical problem is:
The direct-connected button of this connected type mine pipeline, its structure comprises: pin thread, box, described pin thread is cylinder structure, realize and coordinating with box in order to make pin thread, there is annular extension end, described annular is stretched out external diameter and is less than pin thread matrix external diameter, the axially locating that thereby annular extension and pin thread matrix formation sealed step face plays pin thread while coordinating with box, outside annular extension, turning surface is provided with partially trapezoidal outside thread, the end of described annular extension is provided with ring packing projection, described ring packing projection internal diameter is less than annular extension internal diameter, between annular extension and the matrix of pin thread, external diameter is unequal, the matrix middle part of pin thread excessively part is sealed step face.
Box is cylinder structure, the end inner cylindrical surface of box is provided with inclined to one side trapezoidal internal thread, the inclined to one side trapezoidal internal thread part of the end of box and the matrix delivery position of box are provided with circular groove, described circular groove equates with the size of pin thread end ring packing projection, when use, ring packing projection in pin thread end is positioned at the circular groove realization sealing of box, pin thread internal diameter equates with box internal diameter, and pin thread and box external diameter equate.
The utility model has the following advantages:
1. the utility model easy to operate connection that can conveniently realize pipeline simple in structure.
2. when meeting sealing, can improve pipe joint place operating mode, avoid occurring interface fracture.
3. simple in structure, fabricating cost is low, and application is wide.
Brief description of the drawings
Fig. 1 is the utility model entirety sectional drawing.
Fig. 2 is the utility model integral installation figure.
Fig. 3 is the utility model pin thread structural drawing.
Fig. 4 is the utility model box structural drawing.
Fig. 5 is the utility model box sectional drawing.
In figure: 1 pin thread, 11 sealed step faces, 12 partially trapezoidal outside threads, 13 ring packing projections, 2 boxes, 21 inclined to one side trapezoidal internal threads, 22 circular grooves.
Embodiment
As shown in Fig. 1,2,3,4,5: the direct-connected button of connected type mine pipeline, its structure comprises: pin thread 1, box 2, described pin thread 1 is cylinder structure, realize and coordinating with box 2 in order to make pin thread 1, there is annular extension end, described annular is stretched out the matrix external diameter that external diameter is less than pin thread 1, the axially locating that thereby annular extension and pin thread matrix formation sealed step face 11 plays pin thread 1 while coordinating with box 2, outside annular extension, turning surface is provided with partially trapezoidal outside thread 12, the end of described annular extension is provided with ring packing projection 13, described ring packing projection 13 internal diameters are less than annular extension internal diameter, between annular extension and the matrix of pin thread 1, external diameter is unequal, the matrix middle part of pin thread 1 excessively part is sealed step face 11, box 2 is cylinder structure, the end inner cylindrical surface of box 2 is provided with inclined to one side trapezoidal internal thread 21, inclined to one side trapezoidal internal thread 21 parts of the end of box 2 and the matrix delivery position of box 2 are provided with circular groove 22, described circular groove 22 equates with the size of pin thread 1 end annular seal convexity 13, when use, ring packing projection in pin thread end is positioned at the circular groove realization sealing of box, pin thread 1 internal diameter equates with box 2 internal diameters, and pin thread 1 and box 2 external diameters equate.
The direct-connected button of the described connected type mine of the present embodiment pipeline, when use, pin thread 1 and box 2 are located at respectively to the pipeline end that need to be connected, then the pin thread of pipeline end 1 is docked with box 2, realize being connected of pipeline by the partially trapezoidal outside thread 12 of pin thread 1 with the cooperation of the inclined to one side trapezoidal internal thread 21 of box 2.
The above, be only embodiment of the present utility model, and in the scope that those of ordinary skill in the art disclose at the utility model, the variation that can expect easily, within all should being encompassed in the protection domain of model utility.
