Embodiment

[0042] Such as Figure 1~5 As shown, a split nested unilateral bolt fastener installation adapter is used to assist in the installation of split nested unilateral bolt fasteners, such as Figure 7As shown, the bolt fastener includes a bolt 9, a nut 11 and a split gasket 10. The adapter mainly includes a main body and an output mechanism arranged on the main body. The output mechanism includes an inner sleeve 5 and an outer sleeve sleeved outside it. Sleeve 6, the outer casing 2 is in a cylindrical shape, and is sleeved on the outside of the outer sleeve 6. A plurality of pin holes 31 are provided on the cylinder body of the outer casing 2, and the inner sleeve 5 is fixed on the main body casing 2 through three pin shafts 3. The sleeve 6 is connected with the nut 11 , and the inner sleeve 5 is connected with the bolt 9 . One end of the outer sleeve 6 is processed with an internal gear, which is meshed with the outer gear 8 for transmission. The middle part of the outer sleeve...

Abstract

The invention relates to a mounting adapter for a split nested unilateral bolt fastener. The mounting adapter comprises a main body, an inner sleeve (5) fixed on the main body and an outer sleeve (6) arranged outside the inner sleeve (5) in a sleeving manner, wherein the inner sleeve (5) is used for accommodating and fixing a bolt (9); the outer sleeve (6) is connected with a rotation output shaft of a driving mechanism and used for accommodating and driving a nut (11) to rotate; an inner gear is arranged on the inner wall of the outer sleeve (6) and used for being meshed with an outer gear (8) on the rotation output shaft of the driving mechanism; the main body comprises a cylindrical housing (2) arranged outside the outer sleeve (6) in a sleeving manner; hinge pin holes (31) are formed in the cylinder body of the housing (2); circular-arc-shaped holes (32) are formed in the cylinder body of the outer sleeve (6); and hinge pins (3) are fixedly mounted on the outer wall of the inner sleeve (5) and penetrate the corresponding circular-arc-shaped holes (32) and hinge pin holes (31). Compared with the prior art, the mounting adapter has the advantages of small space occupation and high reliability.

Description

technical field [0001] The invention relates to an auxiliary installation tool for single-side bolt fasteners, in particular to a split nested single-side bolt fastener installation adapter. Background technique [0002] At present, in the field of civil engineering and mechanical installation, there is a large demand for the installation of connection and fastening of structural parts. As far as bolts are commonly used at present, when performing connection and fastening operations on components, staff need to work on both sides of the components at the same time, and there is still no good implementation method for unilateral installation. This connection and fastening method has simple structure, convenient operation and good load bearing, but it is only suitable for open cross-section components. In some special occasions, such as connecting and fastening closed cross-section components or components that are inconvenient to operate on the other side , it is impossible ...
