Abstract
An automatic-reset locking mechanism mainly comprises an upper orifice plate, a lower portion inclined-surface base, an inclined-surface cylinder, a reset spring, an L-shaped locking shaft and screw holes and is characterized in that the upper orifice plate is fixed on the upper portion of a sub-frame of a quick replacement device, and a round through hole is arranged in the middle of the upper orifice plate. The lower portion inclined-surface base is fixed on the lower portion of the sub-frame of the quick replacement device and another round through hole is arranged in the middle of the lower portion inclined-surface base. The angle of the inclined-surface of the lower portion inclined-surface base and the angle of the inclined surface of the inclined-surface cylinder are both of 45 degrees. The round through hole is arranged in the middle of the inclined surface cylinder and a bolt hole is arranged on a side face of the inclined-surface cylinder. The L-shaped locking shaft is an L-shaped pin shaft with a bend handle on one end of the L-shaped pin shaft.
Description
The utility model belongs to technical field of engineering machinery, relates to the locking mechanism that automatically resets that fast shifter uses on a kind of micro-multi-purpose engineering machine.
Background technique
Traditional fast shifter is not provided with the locking mechanism that automatically resets, and safety coefficient is low.
Summary of the invention
The purpose of the utility model is a kind of locking mechanism that automatically resets of design, to overcome the deficiency of existing technology.
The utility model solves the technological scheme that its technical problem adopted: two locking mechanisms that automatically reset about being provided with on the sub-frame of fast shifter, and the locking mechanism that automatically resets is made up of upper guard-plate, lower bevel base, surface cylinder body, Returnning spring, L shaped lock shaft; Upper guard-plate is fixed on the sub-frame of fast shifter top, and the centre is provided with a round tube hole, effect be with L shaped lock shaft movingly; The lower bevel base is fixed on the sub-frame of fast shifter bottom; The centre is provided with a round tube hole; Effect be with L shaped lock shaft movingly, 45 ° each other of the bevel angles of its bevel angle and surface cylinder body, its two inclined-planes cooperate the rotation through the surface cylinder body to realize moving up and down of L shaped lock shaft; A round tube hole is set in the middle of the surface cylinder body, effect be with L shaped lock shaft movingly, its side is provided with a screw, with screw surface cylinder body and L shaped lock shaft is fixed into one when effect is assembling; The structure of L shaped lock shaft is the L shaped bearing pin of curved of one one end band.The integral installation distribution structure is: order is placed surface cylinder body, Returnning spring from bottom to top between upper guard-plate and lower bevel base; Then penetrate L shaped lock shaft downwards from the upper guard-plate round tube hole; L shaped lock shaft order from the top down passes upper guard-plate, Returnning spring, surface cylinder body, lower bevel base; At last in the screw of surface cylinder body side surface setting, screw in screw, surface cylinder body and L shaped lock shaft are fixed into one.Working principle is: rotate L shaped lock shaft; With L shaped lock shaft fixedly all-in-one-piece surface cylinder body also on the inclined-plane of lower bevel base, rotate simultaneously; Through moving up and down of two L shaped lock shafts of mutual motion realization that cooperate inclined-planes, thus the release (moving upward) that realizes L shaped lock shaft with lock (moving downward) function.
The beneficial effect of the utility model is: be employed in be provided with on the sub-frame of fast shifter about two locking mechanisms that automatically reset, well solved safety and quick replacing problem.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
1. upper guard-plates among the figure, the 2. sub-frame of fast shifter, 3.L shape lock shaft, 4. Returnning spring, 5. surface cylinder body, 6. lower bevel base, 7. screw.
Embodiment
In Fig. 1, two locking mechanisms that automatically reset about being provided with on the sub-frame 2 of fast shifter, the locking mechanism that automatically resets is made up of upper guard-plate 1, lower bevel base 6, surface cylinder body 5, Returnning spring 4, L shaped lock shaft 3; Upper guard-plate 1 is fixed on the sub-frame of fast shifter 2 tops, and the centre is provided with a round tube hole, effect be with L shaped lock shaft 3 movingly; Lower bevel base 6 is fixed on the sub-frame of fast shifter 2 bottoms; The centre is provided with a round tube hole, effect be with L shaped lock shaft 3 movingly, 45 ° each other of the bevel angles of its bevel angle and surface cylinder body 5; Its two inclined-planes cooperate the rotation through surface cylinder body 5 to realize moving up and down of L shaped lock shaft 3; A round tube hole is set in the middle of the surface cylinder body 5, effect be with L shaped lock shaft 3 movingly, its side is provided with a screw 7; Fixed L shape lock shaft 3 when effect is assembling, the structure of L shaped lock shaft 3 are L shaped bearing pins of curved of one one end band.The integral installation distribution structure is: order is placed surface cylinder body 5, Returnning spring 4 from bottom to top between upper guard-plate 1 and lower bevel base 6; Then penetrate L shaped lock shaft 3 downwards from upper guard-plate 1 round tube hole; L shaped lock shaft 3 order from the top down passes upper guard-plate 1, Returnning spring 4, surface cylinder body 5, lower bevel base 6; In the screw 7 that surface cylinder body 5 sides are provided with, screw in screw at last, surface cylinder body 5 and lock shaft 3 are fixed into one.Working principle is: rotate L shaped lock shaft 3; With L shaped lock shaft 3 fixedly all-in-one-piece surface cylinder body 5 also on the inclined-plane of lower bevel base 6, rotate simultaneously; Through moving up and down of two L shaped lock shafts 3 of mutual motion realization that cooperate inclined-planes, thus the release (moving upward) that realizes L shaped lock shaft 3 with lock (moving downward) function.
