Technical Field
The utility model relates to a technical field of connecting piece, more specifically say, it relates to a combined connection structure.
Background
In various industries, in order to realize the long length of the rod piece or the quick butt joint of two rod pieces, the two rod pieces are combined and butted through a specific connecting piece. The connecting pieces on the market are inconvenient to butt joint during the use process, and the butt joint stability is not particularly ideal.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a not enough to prior art exists, the utility model aims to provide a combined connection structure rational in infrastructure simple, the butt joint is convenient, connects stably.
In order to achieve the above purpose, the utility model provides a following technical scheme:
a combined connecting structure is used for fixedly butting two rod pieces, and comprises a middle cylinder body, a first plug and a second plug, wherein the first plug is in threaded connection with one end of the middle cylinder body, the second plug is in threaded connection with the other end of the middle cylinder body, the first plug and the second plug are of hollow structures, the first plug is connected with a first rod piece, a butting body is connected in the second plug, the second plug is connected with a second rod piece through the butting body,
the butt joint body comprises a butt joint part and an insertion part, and the butt joint part is provided with an external thread for connecting the second rod piece; the diameter of the butt joint part is larger than that of the plug part,
a conical clamping table is formed at the end head of the insertion part, a main body part matched with the inner diameter of the second plug is formed between the conical clamping table and the butt joint part,
the inserting part is composed of a plurality of elastic block spring pieces,
after the elastic sheet of the insertion part is squeezed by force and is tightened to penetrate through the second plug, the elastic sheet is elastically restored and opened to realize the fixation of the insertion part and the second plug.
The utility model discloses further set up to: the elastic sheet is provided with four elastic sheets, and concentric holes are formed among the four elastic sheets.
The utility model discloses further set up to: and the opening of the second plug is chamfered.
Contrast prior art not enough, the beneficial effects of the utility model are that:
the first rod piece penetrates through the first plug, the first plug and the middle barrel are connected, the second plug and the middle barrel are connected, the butt joint body is rapidly pushed into the second plug through pressure equipment to be fixed with the second plug, and finally the second rod piece and the butt joint body are connected to complete the combination of the two rod pieces. The whole installation process is extremely convenient and fast, and the connection stability is strong.

Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural view of the docking body of the present invention.
Detailed Description
Embodiments of the present invention are further described with reference to fig. 1 to 2.
The embodiment has the specific structure that: the connecting structure is used for fixedly butting the two rod pieces. The two bars are respectively a first bar 11 and a second bar 12.
The connection structure is as follows: comprises a middle cylinder body 1, a first plug 2 in threaded connection with one end of the middle cylinder body 1 and a second plug 3 in threaded connection with the other end of the middle cylinder body 1.
The middle cylinder body 1, the first plug 2 and the second plug 3 are hollow structures. The first plug 2 is connected with the first rod 11, the second plug 3 is internally connected with the butt joint body 4, and the second plug 3 is connected with the second rod 12 through the butt joint body 4. The opening of the second plug 3 is chamfered.
The first rod 11 is T-shaped, and after the first rod 11 is inserted into the first plug 2, the end of the first rod is abutted against the first plug 2 to fix the first rod. Then the first plug 2 with the first rod 11 is screwed with the upper end of the middle cylinder 1.
The butt joint body 4 comprises a butt joint part 42 and an insertion part 41, wherein the butt joint part 42 is provided with an external thread for connecting the second rod piece 12; the diameter of the abutment portion 42 is larger than the diameter of the mating portion 41.
The end of the plug portion 41 is formed with a tapered catch 411, and a main body portion 412 adapted to the inner diameter of the second plug 3 is formed between the tapered catch 411 and the abutting portion 42.
The inserting portion 41 is formed by combining four elastic pieces 410, and a concentric hole 40 is formed between the four elastic pieces. A movable gap 4a is arranged between the four spring plates. This four shell fragments can be to the downthehole extrusion of concentric circles when receiving power extrusion, and then make the toper card platform can follow the cavity of second end cap 3 and insert and run through, after the toper card platform runs through second end cap 3, the shell fragment no longer receives the atress, and it receives the influence of elasticity resilience ability, and its self can open, then cooperates butt joint portion 42 to block second end cap 3 on the main part. The diameter and length of the main body are set according to the inner diameter and height of the second plug 3, so that the main body is just sleeved by the second plug 3, and the conical clamping table and the butt joint part 42 are abutted against the second plug 3.
The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
