Embodiment Construction

[0013] figure 1 Shown is a tool 1 for manually installing plastic rivets 2 in order to fix components 3, 4 to each other. For this purpose, the aligned holes 5 in the components 3, 4 are inserted into the base 6 of the plastic rivet 2 with the flaps 7 and then the expansion pins 8 are lowered into the plastic rivet 2, so that the flaps 7 are pushed outwards and form the opposing components 4 of a back cut. The plastic rivet 2 is supported on the component 3 by means of the head 9, so that the components 3, 4 are clamped and fastened to each other.

[0014] For simple manual mounting of the plastic rivet 2 , it is firstly received by the tool 1 in a loss-proof manner. For this purpose, a hole 31 is provided in the elongated guide element 10 of the housing part 28 , which hole receives the expansion pin 8 in a loss-proof manner. Here a clamping device 11 presses the expansion pins 8 against the inner surface of the guide 10 so that expansion pins 8 with different diameters ca...

Abstract

The invention relates to a tool for mounting plastic rivets. Said tool comprises a top, a base having extensible wings, said base being introduced through aligned openings of the components to be connected, and an expansion pin which expands the wings by an axial displacement during mounting. In order to facilitate the mounting of the plastic rivet in inaccessible locations, it is captively received in the tool and the top is forced against the components to be connected. In order to fixate the plastic dowel, a pin which is first axially locked is unlocked and is axially impacted by a pressure element to axially displace the expansion pin.

Description

technical field [0001] The present invention relates to a tool for manually installing plastic rivets. Background technique [0002] Plastic rivets have been known for a long time with a head and with a hole and a base with a flap, in which hole a pin is axially displaceable. It is used for connecting flat components such as wood or plastic plates, sheet metal sheets and / or rails and is used in vehicle bodies, electrical equipment such as switchgear cabinets. For this purpose, aligned holes are provided in these components, through which holes the base with the flaps is introduced. The compression of the head with the components towards the head will result in a narrow gap of the components to be connected. Simultaneously, the expander pin is depressed in the direction of the members, so that the expander forms a back cut from the members towards it and connects these members to each other. [0003] Automatic tools are used for this in industrial assembly. Plastic rivets...
