Description

A kind of quick detach latching device

Technical field

The utility model belongs to a kind of latching device, especially refers to be used for the quick detach latching device on the fold mechanism.

Background technology

Existing fold mechanism mainly adopts hinge folding, and the folding latching device that does not have after folding and launching of hinge uses when also being not suitable for quick detach; The fold mechanism that has has adopted the quick detach instrument as latching device, but can't reach the effect that hides the fold mechanism grooving.

The utility model content

The purpose of this utility model is to provide a kind of and can hides the fold mechanism grooving fully, makes the quick detach latching device of fold mechanism good looking appearance.

For achieving the above object, quick detach latching device of the present utility model, comprise that one one end yoke has two, and be equipped with the quick detach handle of a symmetrical eccentric circular hole respectively, at eccentric part an arc end face is arranged respectively, be with a rotating shaft in the eccentric circular hole of two symmetries, be equipped with an inner bolt hole in the middle of the rotating shaft, other has a upper and lower side to have the bolt of thread segment and following thread segment respectively, the inner bolt hole spiral shell knot of thread segment and rotating shaft on it, be with the packing ring of a band cambered surface on non-threaded section of the bolt, the following thread segment of bolt and a dynamic resistance piece spiral shell knot that has inner bolt hole, it is characterized in that: the line and the quick detach handle center line parallel in the eccentric circular hole center of circle and the eccentric part arc end face center of circle, the packing ring below is with crown cap, is wound with spring on the bolt between crown cap and the dynamic resistance piece.

Preferably, described packing ring is a plastic washers.

Preferably, described dynamic resistance piece is a black nut.

When using the utility model mounting or dismounting fold mechanism, simple and convenient quick, and the utility model quick detach latching device has changed the eccentric position of traditional eccentric, the eccentric circular hole center of circle is parallel with the line of centers of quick detach handle with the line in the eccentric part arc end face center of circle, during the locking fold mechanism, the quick detach handle can turn to and bolt position in the same way by the phase countershaft, reaches the effect that hides the fold mechanism grooving fully, makes the fold mechanism outward appearance more good-looking.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Figure 1 shows that the quick detach handle scheme drawing of prior art quick detach latching device, the line of centers 111 of quick detach handle 1 and line 112 angles in its eccentric circular hole center of circle and the eccentric part arc end face center of circle can't reach the effect that hides the fold mechanism grooving near 90 °.

With reference to Fig. 2 to Fig. 5, quick detach latching device of the present utility model includes one one end yoke two, and be equipped with the quick detach handle 1 of a symmetrical eccentric circular hole 11 respectively, at eccentric part an arc end face is arranged respectively, the line 112 in the eccentric circular hole center of circle and the eccentric part arc end face center of circle is parallel with quick detach handle center line 111, be with a rotating shaft 2 in the eccentric circular hole of two symmetries, be equipped with an inner bolt hole 21 in the middle of the rotating shaft 2, other has a upper and lower side to have the bolt 5 of thread segment 51 and following thread segment 52 respectively, thread segment 51 is tied with inner bolt hole 21 spiral shells of rotating shaft 2 on it, be with the plastic washers 3 of a band cambered surface on non-threaded section of the bolt, the cambered surface radius of plastic washers 3 is identical with the arc end face radius of quick detach handle 1 eccentric part, the following thread segment 52 of bolt and dynamic resistance piece 6 a spiral shells knot that has inner bolt hole, the preferred black nut of dynamic resistance piece herein, also be with on non-threaded section of the bolt crown cap 7 be positioned at plastic washers 3 below, be wound with spring 4 on the bolt between crown cap 7 and the dynamic resistance piece 6, to support the quick detach latching device and in use to locate the quick detach latching device, crown cap 7 can withstand spring 4 and support plastic washers 3.

Because the line 112 in the eccentric circular hole center of circle and the eccentric part arc end face center of circle is parallel with quick detach handle center line 111, quick detach handle 1 energy phase countershaft 2 turn to bolt 5 in the same way and the position of covering bolt 5.

With reference to Fig. 6, Fig. 7 and Fig. 8, when using the utility model locking fold mechanism, the fold mechanism 8 that closes is opened the quick detach latching device, and the quick detach latching device is rotated counterclockwise in the grooving that snaps in fold mechanism 8 around fold mechanism rotating shaft 9.Utilize quick detach handle 1 to clockwise rotate to make the crown cap 7 lower ends fold mechanism loam cake that reclines then, the jam nut 6 fold mechanism rotating shaft 9 that reclines.Again quick detach handle 1 is rotated about 180 degree, make the cambered surface packing of the arc end face and the plastic washers 3 of its eccentric part, because the effect of crown cap 7 and spring 4, quick detach handle 1 can not be shifted and well lock fold mechanism, quick detach handle 1 can the perfect grooving that hides fold mechanism simultaneously.

During dismounting, reversing sense upset quick detach handle 1 about 180 degree clockwise rotate the quick detach latching device then and can open fold mechanism around the rotating shaft 9 of fold mechanism.
