Problems solved by technology

[0005] Problems arise when the parts to be joined are of too great a thickness, since this type of "blind rivet" has a limited length; and when it is desired to disassemble the parts to be joined in the future, the only way is This is done by breaking or drilling the part, which would require damaging and breaking the housing of the rivet

Embodiment Construction

[0027] Taking into account the reference numerals used in the drawings, the system for detachably connecting parts of large thickness is intended for coupling two parts, namely an upper part 1 and another lower part 2, said upper part 1 and said lower part 2 are in direct contact through their respective inner end faces 3 and 4, so that the inner end face 4 of said lower part 2 comprises blind holes 5 provided with first strips for coupling bolts 7 the thread of the end section 6 of the thread, and the insertion of the characteristic elastic washer 8 in such a way that it comes into contact with the inner end face 4 of said lower part 2 and also brings it into contact with the annular extension 9 integrally formed with the bolt 7 itself, This ensures that the screws 7 are fastened to the lower part 2 . Thus, the annular extension 9 separates the lower part 10 corresponding to the lower part 2 from the upper part 11 corresponding to the upper part 1 .

Abstract

The invention relates to a system for the detachable connection of thick parts, intended to connect two parts (1 and 2) that are in contact with one another along the respective inner faces (3 and 4) thereof. One of the aforementioned parts includes a threaded blind hole (5) into which a first threaded end portion (6) of a bolt (7) is inserted, said bolt having an annular extension (9) that limits the tightening rotation of the bolt (7). In addition, the invention includes a characteristic spring washer (8) as a means for blocking the movement of the bolt (7), preventing same from loosening. The other part includes through-holes (13) each housing a segment (11) of the respective bolt (7), a second threaded end portion (14) of the bolt (7) extending beyond said part and being coupled to a self-locking nut (15) which secures the parts to one another.

Description

technical field [0001] As stated in the title of this specification, the present invention relates to a system for releasably unioning parts of large thickness from at least two superimposed layers to be joined together by the contact of one of their end faces , so that we have access to the connection system just through one of the free end faces of one of the parts, but we cannot access the connection system through the free end face of the other of the pair of parts. [0002] The object of the present invention is therefore to achieve a completely reliable connection between the two superimposed parts in question, in order to prevent said parts from being separated from each other, this object being achieved by means of a characteristic connection system. [0003] It is a safety system that prevents the connection from loosening during its lifetime. Background technique [0004] When two or more parts need to be joined together, where there is no way to access the intern...
