Abstract
The invention discloses a bolt fixing connection structure for aluminium profile surface, which is used for fixed connection between an aluminium profile and a component to be mounted, wherein a mounting cavity is arranged on one side of the aluminium profile close to the component to be mounted; a long hole is formed in the external surface of the mounting cavity; a T-shaped bolt or a T-shaped handle of a T-shaped nut penetrates through the long hole and enters the mounting cavity, and is rotated and then clamped into the mounting cavity; a mounting hole is formed in the component to be mounted; the T-shaped bolt penetrates through the mounting hole and is matched with the nut to achieve the fixed connection between the aluminium profile and the component to be mounted; or the bolt penetrates through the mounting hole and is matched with the T-shaped nut to achieve the fixed connection between the aluminium profile and the component to be mounted. The bolt fixing connection structure can meet a strength requirement of bolt fixing on the aluminium profile, is reliable, can bear a larger external force, and is simple in technology; and the component can be mounted only by opening holes, and no other special tools are required.
Description
Technical field
The present invention relates to the field of captiveing joint of motorcar body and miscellaneous part, relate in particular to a kind of for the aluminium shape surface bolt fixed connection structure on the aluminum alloy bus body.
Background technology
After bus body is built and completed, interior trimming parts and the annexes such as handrail, door pump, seat need to be installed on vehicle body usually, because these parts are stressed larger, generally need to be fixed by bolts on vehicle body.For the steel structure bus body, only need to can satisfy installation requirement at the attachment point pre-embedded steel slab, for the passenger vehicle of all-aluminium body structure, comparatively complicated.Major way has two kinds at present: a kind of mode is pre-buried aluminium sheet, and the bolt attachment point is by the mode welding aluminum sheets that aluminium welds on aluminium section bar, and the tapping bolt of rear end plate then punches; Another kind of mode is riveting nut, and riveting nut is installed in the perforate of bolt attachment point on aluminium section bar, by the riveting nut bolt of rear end plate.But above two kinds of bolt mounting meanss owing to being subject to the restriction of the intensity of aluminium own and aluminium weldering intensity, all can not bear larger External Force Acting.
Summary of the invention
Defective in view of above-mentioned prior art exists the objective of the invention is to propose a kind of aluminium shape surface bolt fixed connection structure, makes the constant intensity of bolt can bear larger external force.
Purpose of the present invention will be achieved by the following technical programs:
A kind of aluminium shape surface bolt fixed connection structure, be used for captiveing joint of aluminium section bar and parts to be installed, a side near parts to be installed on described aluminium section bar is provided with an installation cavity, offer a slotted hole on the outside face of described installation cavity, the T-shaped handle of one T-shaped bolt or T-shaped nut passes in the chamber that described slotted hole enters described installation cavity, and after rotation, clamping enters in the chamber of described installation cavity; Offer a mounting hole on described parts to be installed, described T-shaped bolt passes described mounting hole and coordinates with a nut and realize captiveing joint of described aluminium section bar and parts to be installed, and perhaps a bolt passes described mounting hole and coordinates with described T-shaped nut and realize captiveing joint of described aluminium section bar and parts to be installed.
Preferably, above-mentioned a kind of aluminium shape surface bolt fixed connection structure, wherein: on the cross section of described installation cavity, the inwall of a side of close parts to be installed is provided with a boss, and the T-shaped handle of described T-shaped bolt or T-shaped nut is provided with a depression that matches with described boss.
Preferably, above-mentioned a kind of aluminium shape surface bolt fixed connection structure, wherein: described boss is the V-type boss, described depression is the V-type depression.
Preferably, above-mentioned a kind of aluminium shape surface bolt fixed connection structure, wherein: described T-shaped bolt or T-shaped nut can be done endwisely slipping of relatively described slotted hole in the chamber of described installation cavity.
Preferably, above-mentioned a kind of aluminium shape surface bolt fixed connection structure, wherein: the T-shaped handle of described T-shaped bolt or T-shaped nut is oblong or oblique parallelogram.
Outstanding effect of the present invention is: a kind of aluminium shape surface bolt fixed connection structure of the present invention can satisfy the fixing requirement of strength of bolt on aluminium section bar, and reliable in structure can be born larger external force; Match by the depression on the T-shaped handle of the boss in installation cavity and T-shaped bolt or T-shaped nut, can make bolt fixing rear difficult loosening; Can be as required by adjusting T-shaped bolt or the position of T-shaped nut in slotted hole, regulate the installation site of parts to be installed, make install more convenient; Technique is simple, only needs perforate to install, and does not need other special tools.
Following constipation closes the embodiment accompanying drawing, the specific embodiment of the present invention is described in further detail, so that technical solution of the present invention is easier to understand, grasp.
