Abstract
The invention provides a sealing plug structure which comprises an expansion plug and an expansion sleeve. The expansion plug is inserted in the expansion sleeve, and the outer surface of the expansion plug is matched with the inner surface of the expansion sleeve to expand the expansion sleeve. Through the expansion principle, the expansion plug is pressed in the expansion sleeve to expand the expansion sleeve, so that the expansion sleeve can be connected with a matched body, and the sealing effect is achieved. Moreover, the operation process is simple, and time and labor are saved.
Description
Technical field
The present invention relates to field of air conditioning, especially, relate to a kind of seal plug structure.
Background technique
Prior art is to coordinate by the mode of screwing by screwed Plastic cap and corresponding copper nut, reaches the object that do not drop.This mode manufacturing efficiency is low, manual operation difficulty.
Summary of the invention
The object of the invention is to provide a kind of seal plug structure, to solve manual operation difficulty, the technical problem that manufacturing efficiency is low.
For achieving the above object, the invention provides a kind of seal plug structure, comprise expansion plug; Expansion sleeve, expansion plug inserts in expansion sleeve, by coordinating of the outer surface of expansion plug and the internal surface of expansion sleeve expansion sleeve being expanded.
Further, the inner end of expansion sleeve is provided with inside boss.
Further, expansion plug comprises first paragraph and the second segment being set-located, and the diameter of first paragraph is less than the diameter of second segment, and the length of first paragraph is greater than the length of second segment.
Further, between first paragraph and second segment, be provided with space.
Further, boss is a plurality of, and a plurality of boss are provided with gap.
Further, a plurality of boss distribute along even circumferential.
The present invention has following beneficial effect:
The present invention adopts expansion principle, utilizes being pressed into of expansion plug that expansion sleeve is expanded, and reach the object being connected with ligand, thereby reach the effect of sealing, and also simple, time saving and energy saving in operating process.
Except object described above, feature and advantage, the present invention also has other object, feature and advantage.Below with reference to figure, the present invention is further detailed explanation.
Accompanying drawing explanation
The accompanying drawing that forms the application's a part is used to provide a further understanding of the present invention, and schematic description and description of the present invention is used for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is according to the cross-sectional schematic of seal plug structure of the present invention; And
Fig. 2 is according to the schematic diagram of seal plug structure of the present invention.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
Referring to Fig. 1 and Fig. 2, according to seal plug structure of the present invention, comprise expansion plug 10; Expansion sleeve 20, expansion plug 10 inserts in expansion sleeve 20, by making expansion sleeve 20 expand coordinating of the outer surface of expansion plug 10 and the internal surface of expansion sleeve 20.The present invention adopts expansion principle, utilizes being pressed into of expansion plug that expansion sleeve is expanded, and reach the object being connected with ligand, thereby reach the effect of sealing, and also simple, time saving and energy saving in operating process.
Referring to Fig. 1 and Fig. 2, the inner end of expansion sleeve 20 is provided with inside boss 21.Boss 21 is a plurality of, and a plurality of boss 21 are provided with gap.A plurality of boss 21 distribute along even circumferential.
Referring to Fig. 1 and Fig. 2, expansion plug 10 comprises first paragraph 11 and the second segment 12 being set-located, and the diameter of first paragraph 11 is less than the diameter of second segment 12, and the length of first paragraph 11 is greater than the length of second segment 12.。Between first paragraph 11 and second segment 12, be provided with space.
The present invention is comprised of two-part, expansion plug 10, and similar cylindrical structural, Main Function is in compaction process, plays the boss 21 of expansion sleeve 20 openings is expanded.Expansion sleeve 20, similar cirque structure, has certain elasticity, and be mainly has a boss 21 on each petal-like tooth of opening end, after coordinating with expansion plug 10, backs down each tooth, and total and nut are closely cooperated.
As can be seen from the above description, the above embodiments of the present invention have realized following technique effect:
The present invention adopts expansion principle, utilizes being pressed into of expansion plug that expansion sleeve is expanded, and reach the object being connected with ligand, thereby reach the effect of sealing, and also simple, time saving and energy saving in operating process.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
