It preferably, further include guide pin and elastic device inside the latch, the guide pin is suspended on by cross bar The through hole of the latch upper end setting, and the guide pin passes through inside elastic device, faces the logical of slider bottom Hole.

Preferably, the through-hole of latch upper end setting is vertical ellipse, and the cross bar of guide pin can be made to move up and down, To meet the change in location of unlock with guide pin when locking.

Preferably, the elastic device is spring and disc spring, and the latch is divided into upper and lower ends by intermediate partition, The upper end of partition is arranged in the disc spring, and the lower end of partition is arranged in the spring.

Preferably, through hole is arranged in one end of the sliding block, for connecting chair leg.

Preferably, leg lock further includes sliding rail, and the limiting slot being adapted with slide block wheel is arranged on the sliding rail.

Preferably, in order to sliding block is fixed on the ground or aircraft cabin inside, the sliding rail both ends be arranged groove, and Through-hole is arranged in bottom portion of groove, passes through through-hole using bolt and is fixed on ground.

The beneficial effects of the utility model are:

The purpose of this utility model is that for helicopter crew's seat provide it is a kind of it is small and exquisite, efficiently chair leg is locked, not by Tool realizes the quick unlatching of chair leg lock, closure, and chair leg locking can be fitted tightly over one with the sliding rail on airplane floor when closing It rises, and then entire seat will not shake.

Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality It is further elaborated with novel.It should be appreciated that the specific embodiments described herein are only used to explain that this is practical It is novel, it is not used to limit the utility model.

Embodiment

The present embodiment provides a kind of new-type chair legs to lock, as shown in Figure 1, chair leg lock is divided into two parts, lock body and sliding rail, institute Stating lock body includes sliding block, spanner, latch and fast bolt, one end of the spanner by the rotating pin of the sliding block with it is described The other end of sliding block rotation connection, the spanner and the sliding block is respectively provided with through-hole, passes through the through-hole using the fast bolt So that the spanner and the sliding block are fixed, the latch is mounted among the spanner and the sliding block.

As shown in figure 5, the latch includes guide pin and elastic device, guide pin is suspended on the stop by cross bar The through hole of upper end setting is sold, and the guide pin passes through inside elastic device, faces the through-hole of slider bottom setting.

The elastic device is spring and disc spring, and the latch is divided into upper and lower ends, the dish by intermediate partition Spring setting is arranged in upper end, the spring in lower end.

The sliding rail is to design according to professional standard HB6870, and the limiting slot being adapted with slide block wheel is provided on sliding rail, Simultaneously for fixed rack, it is arranged on the slide rail fluted, and through-hole is set in groove, passes through through-hole using bolt and is consolidated It is fixed.

It is worth noting that, the through-hole of latch upper end setting is vertical ellipse, can make on the cross bar of guide pin Lower movement, to meet the change in location of unlock with guide pin when locking；It is additionally provided on sliding block for connecting chair leg to be locked Chair leg locking can be scheduled in chair leg by through hole with bolt.

When locking using chair leg, the slide block wheel on lock body sliding block is placed into the corresponding region of sliding rail first, it then will lock Body is moved forward or rearward a small distance, so that slide block wheel is stuck in the narrow zone of pulley, is then made with hand by lower ejector lever Through-hole alignment on spanner and sliding block, passes through through-hole for fast bolt, locking process can be completed.In lock state, because pulling Hand is fixed with sliding block, and spanner has downward pressure at this time, so that the through-hole of guide pin insertion sliding block bottom end, latch and sliding rail squeeze While press contacts, disc spring produces a upward reaction force, lock body total is up lifted, such as Fig. 7, the cunning of lock body Mutual extrusion between block wheel and sliding rail generates biggish frictional force, anti-sliding stop, to play locking effect.

When to be unlocked, only spanner need to be pressed lightly on hand down, then click the raised button of fast bolt, it can be light Pine takes out fast bolt, completes unlocking process.

By using above-mentioned technical proposal disclosed by the utility model, following beneficial effect has been obtained:

The purpose of this utility model is that for helicopter crew's seat provide it is a kind of it is small and exquisite, efficiently chair leg is locked, not by Other tools can realize the quick unlatching of chair leg lock, closure, and chair leg locking can be tight with the sliding rail on airplane floor when closing It is closely connected to be combined, and then entire seat will not shake.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and Retouching should also regard the protection scope of the utility model.
