Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, in an embodiment of the present invention, a safety quick buckle includes a buckle base plate 1 and a buckle riser 2, two vertical buckle plates 2 are vertically and oppositely fixed at the front side and the rear side of the buckle base plate 1, the middle parts of the panels of the two vertical buckle plates 2 are oppositely penetrated and provided with installation shaft holes 3, a rotating shaft 9 is rotatably arranged in the mounting shaft hole 3 in a penetrating way, one end of the rotating shaft 9 is provided with an elastic force driving buckle vertical plate 2 to rotate a spring 8 anticlockwise, a limiting groove 10 which is communicated from front to back is arranged between the right side wall of the buckle vertical plate 2 and the buckle base plate 1, a limiting block 11 which prevents the buckle vertical plate 2 from rotating anticlockwise is clamped in the limiting groove 10, the top is installed at buckle riser 2's top and is curved arc eave tile 4, is equipped with the half hole of buckle 5 that is used for the card to establish movable part 12 between arc eave tile 4 and buckle riser 2 top, half hole of buckle 5 is not the collineation with the hole central line in installation shaft hole 3 in the vertical direction.

Installation shaft hole 3 rotates through pivot 9 to be fixed on mounting panel 13 front panel, stopper 11 vertical fixation is on mounting panel 13 in front, and stopper 11 penetrates in spacing groove 10 and meets with spacing groove 10 tank bottom.

Spacing groove 10 is enclosed to close by last spacing arch 6 and lower limiting plate 7 and forms, go up protruding 6 of spacing and fix on the right side wall of buckle riser 2, lower limiting plate 7 is fixed at the right side wall of buckle base plate 1 and is even as an organic whole with buckle base plate 1.

Lower limiting plate 7 inclines upward angle of elevation setting, and area of contact when mainly improving lower limiting plate 7 top surface and 11 bottom surfaces contacts, the contact is more smooth-going, the laminating.

The spring 8 is a flat spiral spring, the inner ring of the spring 8 is fixed on the rod wall of the rotating shaft 9, and the outer end point of the outer ring of the spring 8 is fixed on the panel of the buckle substrate 1.

The utility model discloses a theory of operation is: the utility model provides a spring 8 which provides force to make the buckle have a tendency of rotating anticlockwise around the mounting shaft hole 3 but stop when the lower limit plate 7 contacts with the bottom surface of the limit block 11, when the movable part 12 needs to be clamped in the buckle half-hole 5 in the downward movement, the movable part contacts with the upper arc of the arc-shaped hook head 4 to generate a force A perpendicular to the contact surface, because of the influence of offset and arc surface, the force A does not pass through the axis of the mounting shaft hole 3, so that the buckle rotates around the axis of the mounting shaft hole 3, the movable part 12 is smoothly clamped in the buckle half-hole 5 by overcoming the influence of the spring 8, no external force is applied to the buckle to make the movable part 12 separate from the buckle half-hole 5, the movable part 12 applies to the buckle force B because of the offset T, the force makes the buckle have the tendency of rotating anticlockwise around the mounting shaft hole 3, the tendency of locking deadly separates the movable part 12 from the movement of the buckle riser 2, the movable part 12 can only be disengaged from the catch half-hole 5 by applying a force in direction D in the position shown in the figure, which deflects the catch.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
