Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0035] like figure 1 and figure 2 As shown, a deformation and shrinkage self-recovering unilateral bolt fastener installation tool is used to install unilateral bolt fasteners. The unilateral bolt fasteners include round head bolts 5a connected in sequence and several split gasket 4a, sleeve 5b, washer 5c and nut 5d. The installation tool includes guide rod 3, elastic fixing ring 4b and gasket clip 2. Several split gaskets 4a are connected as a whole through elastic fixing ring 4b to form a deformed and contracted self. Reply split spacer 4, such as Figure 5 As shown, the guide r...

Abstract

The invention relates to a deformation retraction self-recovery type mounting tool for a unilateral bolt fastener. The mounting tool comprises a guide rod, an elastic fixing ring and a gasket clamp, wherein a plurality of separated gaskets are integrally connected by the elastic fixing ring to form a deformation retraction self-recovery type separated gasket; the guide rod is provided with a bending groove; the deformation retraction self-recovery type separated gasket penetrates into the guide rod and is hung on the bending groove along the guide rod; the gaskets are clamped on the guide rod and are used for clamping the deformation retraction self-recovery type separated gasket along the guide rod, so that the deformation retraction self-recovery type separated gasket is changed from a circular shape into a flat shape. Compared with the prior art, the mounting tool disclosed by the invention is capable of realizing rapid installation of the unilateral bolt fastener, is also capable of dismounting the unilateral bolt fastener as needed, and is high in reutilization rate.

Description

technical field [0001] The invention relates to the technical fields of civil engineering and mechanical assembly, in particular to a deformation and shrinkage self-recovering single-side bolt fastener installation tool. 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, workers need to work on both sides of the component at the same time, that is, insert a bolt with a nut on one side, and then use a tool to tighten the nut on the other side . 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 in...
