Abstract
The utility model discloses an expansion fixing connection structure, comprising a hollow thick pipe body and a thin pipe body, wherein the thin pipe body is inserted into the thick pipe body, and the cross section of the thin pipe body is provided with a gap. An expansion device is arranged in the thin pipe body and comprises wedge blocks, expansion blocks and leading screws, and the wedge blocks are fixedly connected with the inner wall of the thin pipe body. The leading screws are axially arranged on the middle axis of the thin pipe body, and the expansion blocks are in screwing match with the leading screws. The expansion blocks can be in butting match with the wedge blocks, and the expansion blocks and the wedge blocks are respectively and symmetrically designed into two sets about the cross section of the thin pipe body. The leading screws are rotatablely connected with a supporting frame, and the outer ends of the leading screws are provided with turnplate handles. The structure can be used for working occasions on which two components are adjusted in the axial distance, and the structure has strong practicality and is easily promoted and applied.
Description
Technical field
The utility model relates to the new structure that removably connects between a kind of member, relates in particular to a kind of swelling fixed connection structure.
Background technique
At present; the a variety of modes that removably connect are arranged between the member; modal is exactly being threaded by screw bolt and nut; be threaded and have the irreplaceable advantage of a lot of Placements; but it needs the workplace of adjustable range to exist certain defective at two members, needs instruments such as spanner during such as dismounting, and is more loaded down with trivial details; and often can occur becoming flexible in the big stressed or vibration occasion that has under the alternate load, will cause fixedly connected inefficacy or the fault that is associated like this.
The model utility content
The utility model is in order to solve deficiency of the prior art, provide a kind of easy and simple to handle, be easy to dismounting, fixed swelling fixed connection structure.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: the swelling fixed connection structure, comprise the extra heavy pipe body and the capillary base of hollow, and capillary base is plugged in the extra heavy pipe body, and described capillary base cross section has breach, is provided with swelling device in the capillary base.
Described swelling device comprises the wedge-shaped blocks of fixedlying connected with the capillary base inwall, expand piece and leading screw, and lead screw shaft is to being located on the capillary base medial axis, expand piece and leading screw threaded, and bloated piece can cooperate with the wedge-shaped blocks roof pressure.
Described bloated piece and wedge-shaped blocks are symmetrical arranged two covers about the capillary base cross section respectively.
Described leading screw is rotatably connected on the supporting frame, and the leading screw outer end is provided with the rotating disk handle.
Adopt said structure, swelling device is when the swelling of capillary base inside, and the breach on the capillary base broadens, and capillary base and extra heavy pipe body are fixedly connected on one; By rotational lead screw the piece that expands is moved axially along leading screw, the piece that expands cooperates with the wedge-shaped blocks roof pressure or separates, and when roof pressure cooperated, capillary base and extra heavy pipe body were connected to one, and during separation, the capillary base of can stretching or extra heavy pipe body move to axial it; Expand piece and wedge-shaped blocks is symmetrical arranged two covers about the capillary base cross section respectively, and two expand pieces and screw pair rotation directions of leading screw are provided with on the contrary, and the surface of contact when making bloated piece and the cooperation of wedge-shaped blocks roof pressure is bigger, stressed more even; Handle with sleeve has made things convenient for the operation to leading screw.The utility model modern design, simple in structure, easy operating provide a kind of new structure, this structure can be used for two members and have carried out the workplace that axial distance is regulated for removably connecting, practical, are easy to apply.
