Fixing device for narrow space

Abstract

The invention discloses a fixing device for a narrow space. The fixing device comprises a supporting seat, a connecting seat and a movable assembly. The supporting seat comprises a supporting face. The connecting seat is provided with sliding rails and external holes. The movable assembly is provided with a pressing piece and sliding pieces, the pressing piece is provided with an inclined face facing the sliding pieces, and a pressing space is formed between the lower surface of the pressing piece and the supporting face. The sliding pieces are connected with the sliding rails in a slidable mode, an internal thread hole with an internal thread is formed in each sliding piece, and the sliding pieces are pressed on the inclined face. A rotating rod is connected to the external connection holes in a rotatable mode and is screwed with the internal threaded holes. When the rotating rod is rotated, the sliding pieces can slide along the sliding rails, the sliding pieces are pressed on different parts of the inclined face, and then the pressing piece is driven to slide up and down along a containing groove so that the height of the pressing space can be increased or decreased. The fixing device for the narrow space can be assembled and disassembled in the direction perpendicular to the connecting and fixing direction, and the difficulty that fixing and operation are difficult due to insufficient space in the connecting and fixing direction is overcome.

Description

technical field [0001] The invention relates to the technical field of fixing structures, in particular to a fixing device used in narrow spaces. Background technique [0002] The connection and fixation between workpieces or parts is very common in daily production and life. The more commonly used connection and fixing structures include bolt structures, compression or clamping structures, etc., but such structures generally need to be in the same direction as the connection and fixing direction. For fixing operation, in general, when there is enough space to connect the fixing direction, it is convenient to use tools such as screwdrivers for fixing operation. [0003] However, in production and manufacturing, there are some workpieces or parts that need to be fixed in a narrow space. If the space for the connection and fixing direction is just located on the narrow side of the narrow space, and there is not enough space for work, then the general connection and fixation me...

Problems solved by technology

[0003] However, in production and manufacturing, there are some workpieces or parts that need to be fixed in a narrow space. If the space for the connection and fixing direction is just located on the narrow side of the narrow space, and there is not enough space for work, then the general connection and fixation method is used. The structure is difficult to complete the installation and fixation

In this regard, some solutions have appeared, such as magnetic adsorption positioning or wedge positioning, but the magnetic adsorption positioning is limited by the material, and a large part of the workpiece material does not meet the requirements; and the wedge positioning program is in It is difficult to remove when disassembled, and some other fixing solutions require special tools to complete the installation

None of these solutions can well solve the problem of fixing workpieces in narrow spaces
