Embodiment
Fig. 1 and Fig. 2 show an embodiment according to quick-locking device of the present utility model.As can be seen from the figure, this quick-locking device comprises panel base 10, tie down screw 40, latch segment 20 and latch mechanism, one end of tie down screw 40 is fixed on the panel base 10, and latch segment 20 is slidably mounted on this tie down screw, and latch mechanism moves along tie down screw 40 and promotes latch segment and shift to panel base 20.In this embodiment, latch mechanism comprises middleware 50 and locking knob 60, wherein middleware is configured to the tube-like piece (referring to Fig. 3 c) that periphery wall is provided with spline, its pore offers the internal thread that matches with tie down screw 40, thereby middleware 50 is threaded with tie down screw 40, and middleware 50 is connected with locking knob 60 by spline structure, make locking knob 60 relatively middleware 50 endwisely slip and relatively middleware 50 cooperate rotationally.
By above-mentioned configuration, when panel base 10 moves latch segment 20,, move towards latch segment 20 thereby drive middleware 50, and then promotion latch segment 20 moves towards panel base 10 along locking direction rotation lock knob 60 at needs.When the mobile latch segment 20 of needs leaves panel base 10, along unlocking direction rotation lock knob 60, move along the direction of leaving latch segment 20 thereby drive middleware 50, just can remove locking to latch segment 20.In the above-described embodiments, the locking direction setting of locking knob 60 is a clockwise direction, and the unlocking direction of locking knob 60 is set at counterclockwise.
Advantageously, in the utility model, quick-locking device is provided with lockable mechanism, and it is used for preventing that maloperation from opening latch mechanism when latch segment 20 remains on locked position, promptly turn locking knob 60 along unlocking direction.Referring to Fig. 3 a to Fig. 3 c, lockable mechanism comprises first lug boss 120 on locking knob 60 sides that is arranged on latch segment 20 and is arranged on second lug boss 160 that matches with first lug boss 120 on the locking knob 60.As can be seen from the figure, first lug boss 120 has first composition surface 12 and first mild face 11, the second lug bosses 160 have second composition surface 32 and the second mild face 31.
When for example counterclockwise turning locking knob 60 from locked position along unlocking direction, first composition surface 12 engages with second composition surface 32, thereby stops this locking knob 60 further to rotate, and opens latch mechanism to prevent maloperation from turning locking knob.Referring to Fig. 5 b, remove locking if desired to latch segment 20, outwards need then that this locking knob 60 of pulling breaks away from this first composition surface 12 and this second composition surface 32, could further turn this locking knob and open this latch mechanism thereby remove first lug boss 120 and second lug boss 160.Latch segment 20 is being shifted in the process of panel base 10, edge locking direction for example clockwise direction turns locking knob 60, the second mild face 31 will slip over from the second mild face 11, and can not hinder the further rotation of locking knob 60, thereby can be rotated further locking knob 60, drive middleware 50 and be rotated further, and then promote latch segment 20 the fast-assembling plate is locked on this quick-locking device, the fast-assembling plate can only be along a direction translation in this case.
Fig. 4 a and Fig. 4 b show the skeleton view that is in locking state according to quick-locking device of the present utility model.As can be seen, under locking state, first composition surface 12 and second composition surface 32 can not overlap from Fig. 4 a, have a certain included angle A between two faces.If maloperation has for example counterclockwise turned locking knob 60 along unlocking direction, this locking knob also can only rotate counterclockwise angle A, makes first lug boss 120 and second lug boss, 160 joints and makes locking knob 60 be in lockup state.
Fig. 5 a and Fig. 5 b show the synoptic diagram that is in lockup state according to quick-locking device of the present utility model respectively, as can be seen from the figure, under lockup state, first composition surface 12 and second composition surface 32 overlap, in this case, can not continue unlocking direction and for example turn locking knob in the counterclockwise direction, thereby avoid maloperation to open quick-locking device and the fast-assembling plate is broken away from, the fast-assembling plate breaks away from the camera that might cause adorning thereon and is damaged.
Fig. 6 a and Fig. 6 b show the synoptic diagram that is in full open position according to quick-locking device of the present utility model respectively.Open quick-locking device if desired, releasing is to the locking of fast-assembling plate, can be along the direction pulling locking knob 60 that leaves panel base 10, first composition surface 12 and second composition surface 32 are broken away from, thereby remove the joint of first lug boss 120 and second lug boss 160, and then can for example counterclockwise turn locking knob 60 along unlocking direction, drive middleware 50 simultaneously and be rotated away from latch segment 50.
According to the utility model, described middleware 50 can be configured to the outer-hexagonal nut, and an end of this locking knob 60 offers the inner hexagonal hole that matches with this outer-hexagonal nut.In another embodiment, middleware 50 can be provided with the nut of spline for the outside, and an end of locking knob 60 offers the hole of matching with this nut.
Advantageously, between panel base 10 and latch segment 20, also be provided with back-moving spring 30.One end of this back-moving spring 30 is installed on the panel base, and the other end withstands latch segment, and when unclamping latch mechanism, back-moving spring rebounds latch segment does not have the preceding position of locking, thereby the fast-assembling plate on the panel base 10 can be unloaded.
At last, should be appreciated that it is exemplary and nonrestrictive more than describing, for the those skilled in the art that read above explanation, except given embodiment, under the prerequisite that does not exceed the utility model scope, it will be conspicuous that many changes and being equal to substitute.In addition, though the utility model is primarily aimed at photographic goods, for the instrument of surveying and mapping with similar structures and observation instrument such as telescope etc., the utility model also is suitable for.
