Abstract
The utility model discloses a quick-dismantling safe plug pin. The quick-dismantling safe plug pin is a plug pin which is composed of a pin shaft body and a safe device which is arranged at the front end of the pin shaft body. The plug pin is formed by a safety device arranged at the front end of the pin shaft body. A fork groove (6) is manufactured at the front end of the pin shaft and the fork groove is an L-shaped blind groove in the axial direction. A blind groove gap (10) is manufactured at the front end of a slot of the L-shaped blind groove (8). The blind groove gap of the pin shaft (5) is provided with a rotatory safety plate (1) through a hinged shaft and a reversing spring. The fixing end of the safety plate is connected with the blind groove gap of the hinged shaft in a movable mode, and the fixing end of the safety plate forms a free state with 30 degrees to 60 degrees protruding an axis of the pin shaft (5) under the combined action of a spring force role and a fastening inclined plane (7) at the front end of the blind groove gap. According to the dismantling quickly safe plug pin, the rotatory safety plate arranged at the front end of the pin shaft forms a stopping side protruding the surface of the pin shaft under a normal state with the spring force role, the plug pin can not withdraw from a pin hole after the plug pin is inserted into the pin hole of a workpiece. The problems that the pin shaft resonates in a vibrating environment and the plug pin is prone to withdraw and drop are avoided.
Description
Technical field

Among the figure: 1. guard plate, 2. hinging shaft, 3. central spindle of the spring, 4. curved spring, 5. bearing pin, 6. fork pockets, 7. inclined-plane, 8.L shape blind slot, 9.L shape stepped slot, 10. blind slot breach.
Embodiment
Consult Fig. 1～Fig. 4 and show a most preferred embodiment of the present utility model.This quick-release safety pin is comprised of the safety installations of an improved bearing pin 5 and its front end setting, and safety installations mainly is comprised of parts such as guard plate 1, hinging shaft 2, central spindle of the spring 3, torsion springs 4.Guard plate 1 is certain thickness steel plate.At bearing pin 5 front ends fork pockets 6 processed, fork pockets 6 is axial L shaped blind slots, and L shaped blind slot 8 slotted eye front ends are shaped with blind slot breach 10.Blind slot breach 10 places are shaped with and are 30 °～60 ° stop inclined-plane 7 with bearing pin 5 axis, and stop inclined-plane 7 is positioned at the below of hinging shaft 2, and is preferably 45 °.On the blind slot breach 10 of bearing pin 5, be provided with one by the rotatable guard plate 1 of hinging shaft and curved spring, the fixed end of described guard plate 1 is connected in the blind slot breach 10 of described hinging shaft actively, under the acting in conjunction on the stop inclined-plane 7 of spring-force driven dual and blind slot breach 10 front ends, form and protrude from the free state that bearing pin 5 axis are 30 °～60 °.One side of guard plate 1 is shaped with relatively the L shaped stepped slot 9 symmetrical with the axial L shaped blind slot of above-mentioned fork pockets 68, guard plate 1 is by being used for the central spindle of the spring 3 of supporting torsion spring 4 on the hinging shaft 2, be connected to actively in the described blind slot breach of fixed end of guard plate 1, rotate in the blind slot breach around hinging shaft 2.Bearing pin 5 can be a polished rod, also can be one with the body of rod of Step Shaft.Hinging shaft 2 is fixed in the pin-and-hole of bearing pin 5, and central spindle of the spring 3 forms interference fit or is welded on the guard plate 1 with guard plate 1 and forms one, with guard plate 1 rotation.Two torque force sides of torsion spring 4 are separately fixed in the variable rectangular groove of L shaped stepped slot 9 formations of going up up and down of guard plate 1 and bearing pin 5, apply certain warping force that resets for guard plate 1.Under normal circumstances (unartificial serviceability), guard plate 1 is spacing lower spring-force driven dual and stop inclined-plane 7, and is at 45 ° with the axis of bearing pin 5.When before needs insert pin-and-hole with latch or from pin-and-hole, withdrawing from, the handling portion of manually-operable guard plate 1 left end then, guard plate 1 is rotated clockwise to and bearing pin parallel position (0 °), L shaped stepped slot 9 on the guard plate 1 compresses torsion spring 4 simultaneously, and behind the insertion pin-and-hole, guard plate 1 is under the reaction force of spring force, nature is rotated counterclockwise around hinging shaft 2, reset to 45 ° of states, guard plate 1 right-hand member protrudes from the bearing pin surface all the time, effectively prevents naturally withdrawing from of bearing pin.
Before latch inserts pin-and-hole, the axis that rotates guard plate 1 and bearing pin 5 with hand is parastate, at this moment, guard plate 1 is within the breach of bearing pin 5 left ends, guard plate 1 is inserted in the workpiece pin-and-hole with latch 5, until the optical axis of bearing pin 5 enter and with pin-and-hole form cooperate after, guard plate 1 is rotated counterclockwise under the effect of spring 4, until its bottom abuts against on 45 ° of stop inclined-planes 7 in the bearing pin 5 left end blind slot breach 10, at this moment, guard plate 1 one ends protrude from the surface of bearing pin 5, form the prevent surface of certain altitude, and whole latch all can not be withdrawn from pin-and-hole in the situation of unartificial operation.45 ° of stop inclined-planes 7 have played position-limiting action, and torsion spring 4 breaks away from guard plate 1 when preventing that guard plate 1 from continuing to rotate counterclockwise, and remain simultaneously to give guard plate 1 certain pretightening force.
The above has done detailed description to embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-described embodiment, in the ken that those of ordinary skills possess, can also make many variations to it.For example, in the above-described embodiments, according to the thickness of spring material, the scope of reversing of spring, the stop inclined-plane 7 of bearing pin 5 left ends can be 30 °, 60 ° etc.If hinging shaft 2 sizes suitably strengthen in the said structure of the present invention, both as supporting axle, as central spindle of the spring, obviously can cancel central spindle of the spring 3 simultaneously.
