Abstract
The utility model provides a transmission set structure of the linear transmission mechanism, which is mainly driven by the motor and the drive components and makes the transmission set perform the linear telescopic movement; the transmission set structure consists essentially of a pipe piece, a screw rod, a main screw cap, a locating ring and a pair of sub screw caps, wherein the main screw cap, the locating ring and the sub screw cap are pressed by the end of the pipe piece and thus combined and fixed inside the pipe piece, therefore making each component not disengage from the axial direction in the pipe piece; as a result, when the main screw cap is damaged, the sub screw cap can replace the original load-bearing function of the main screw cap, so as to avoid the dangerous incidents arisen by the instant sinkage of the transmission set, and further improve the use safety of the linear transmission mechanism; meanwhile, after replacing the original load-bearing function of the main screw cap, the sub screw cap does not disengage from the inside of the pipe piece, therefore, after the main screw cap of the transmission set is damaged, the transmission set can also make the linear telescopic movement.
Description
Technical field
The utility model relates to linear drive, is meant a kind of transmission group structure of linear drive especially.
Background technique
As shown in figure 12, be the sectional drawing that shows existing linear drive, its transmission group 80 mainly is to drive by institutes such as motor 81 and driven units 82, makes this transmission group 80 be made linear fore and aft motion.And this transmission group 80 is in long-term transmission process, can be because nut 84 materials of the driving screw 83 that its metal is made and plastic cement manufacturing different, and cause both that the phenomenon of debentition is arranged, make transmission group 80 can't bear the load of original carrying at last, and the situation that moment sinks is arranged, cause the generation of hazard event.
In view of the above, as shown in figure 13, it is the perspective exploded view that shows the nut block distribution structure of linear drive, it mainly is to be located on this driving screw 91 by spiral shell also can solve above-mentioned disappearance with Safety nut 93 along its main nut 92 of axially making linear displacement, by main nut 92 when the debentition, can see through the function that this Safety nut 93 replaces main nut 92 original bearing loads, add that both have the design of elasticity escape, therefore can allow the user discover the damage of this linear drive easily, use the Security of guaranteeing that this linear drive uses.But this skill commonly used uses situation still to have the defective that need improve immediately in reality:
Owing to be to link each other between this main nut 92 and the Safety nut 93 in the mode that elastic force fastens, and its with spring chuck 94 only radially to fasten this main nut 92 and Safety nut 93, therefore, have the possibility of axial disengaging between this main nut 92 and the Safety nut 93, and the factor that the reason of its disengaging shakes may be by start the time is caused, perhaps this Safety nut 93 original load that carries is greater than the radially fastening power of this Safety nut 93 with main nut 92 ... or the like, all can cause this main nut 92 and Safety nut 93 both axial disengagings, in view of the above, skill commonly used is only as informing that this linear drive of user damages, and can't really guarantee the safety that the user uses, and, then can't carry out linear fore and aft motion again once this linear drive damages.
Therefore, real necessity that has further improvement to progress greatly of obvious above-mentioned linear drive commonly used.
Summary of the invention
