Description
Technical field
This utility model relates to a kind of deployable and collapsible seat.Specifically, the locking mechanism that the relieving state of the deployable and collapsible seat on helicopter is fixed it is used to.
Background technology
At present, its backboard frame of seat used on helicopter is mostly can folding and unfolding seat, in order to when needed backboard frame is decontroled into setting shape, it is not necessary to time backboard taken in into parallel with seat horizontal.Wherein, it is both provided with locking mechanism between backboard and seat board abutting end.Traditional locking mechanism is at the montant lower end, both sides of backboard frame and the corresponding seat board frame both sides equal pin hole processing of rod rear end, when backboard frame by take in State Transferring become use state time, first backboard frame is pulled out, and make the pin-and-hole of montant lower end, backboard frame both sides corresponding with the pin-and-hole of seat board both sides rod rear end, it is inserted into pin, realizes the locking between backboard frame and seat board frame with this.Due to backboard frame by take in State Transferring become use state time, need the pin-and-hole that backboard frame first pulls out, and makes montant lower end, backboard frame both sides corresponding with the pin-and-hole of seat board frame both sides rod rear end, be inserted into pin, the locking between backboard frame and seat board frame could be realized, operate cumbersome.Again owing to using latch insertion pin-and-hole to realize locking, between latch and pin-and-hole, gap is bigger so that between the two, frictional force is relatively big, easily weares and teares.Therefore, using the seat of this locking mechanism, service life is the longest.
Utility model content
Problem to be solved in the utility model is to provide a kind of deployable and collapsible seat locking mechanism.This locking mechanism, operates more convenient.Use this locking mechanism, the service life of seat can be extended.
The problems referred to above to be solved in the utility model are realized by techniques below scheme:
Deployable and collapsible seat locking mechanism of the present utility model includes the seat frame for fixing seat and the backboard frame for stationary backplate, the first cross bar that described seat frame is parallel to each other by two vertical poles being parallel to each other and two forms, the opposite sides of two vertical poles all has rail groove, all there is the first capping the front end of two vertical poles, and one section, the rear end of two vertical poles is all bent upwards in arc-shaped.Described backboard frame is the rectangular frame being formed by connecting by two montants and at least two the second cross bar, spacing between being smaller than inside two vertical poles between outside two montants, all there is roller in the outside of the neighbouring lower end of two montants, two rollers are respectively placed in the rail groove of corresponding vertical pole, and described backboard frame can be taken in into horizontal by rail groove and two rollers or decontrol into approximation setting shape.It is characterized in the rear inside of two vertical poles and between the corresponding montant of backboard frame, all has lock banking stop, one, the top of lock banking stop by hinge in the rear inside of corresponding vertical pole, it is connected with pull bar between the other end, top of two lock banking stops, inside the lock banking stop of adjacent rod two ends junction point and between the adjacent back end of corresponding vertical pole, is all connected with extension spring.All there is lower convexity the most neighbouring middle of described lock banking stop, and all there is the crotch towards the bending of vertical pole rear end in the outside of lower convexity.Two montants all have backing pin adjacent to the outside of its lower end, and described backing pin is all the most corresponding with corresponding crotch and is all caught on by crotch.
As can be seen from the above scheme, owing to the rear inside of two vertical poles is provided with lock banking stop between the corresponding montant of backboard frame, one, the top of lock banking stop by hinge in the rear inside of corresponding vertical pole, it is connected with pull bar between the other end, top of two lock banking stops, inside the lock banking stop of adjacent rod two ends junction point and between the adjacent back end of corresponding vertical pole, is all connected with extension spring.All there is lower convexity the most neighbouring middle of described lock banking stop, and all there is the crotch towards the bending of vertical pole rear end in the outside of lower convexity.Two montants all have backing pin adjacent to the outside of its lower end, and described backing pin is all the most corresponding with corresponding crotch and is all caught on by crotch.When backboard frame income being the level of state, as long as hand-pulling pull bar upwards to lift, while spring is stretched, make lock banking stop around the bearing pin upwards back rotation of one, its top, until making hook under lock banking stop be separated with the backing pin of backboard frame two montant lower end outside, backboard frame can be taken in into horizontal.When backboard frame being decontroled in upright state, reverse operating above-mentioned steps, operate very convenient.Realize locking owing to inserting pin-and-hole without latch again, it is to avoid between latch and pin-and-hole, gap is relatively big and that bring frictional force abrasion condition bigger, easy occurs.Therefore, use the seat of this locking mechanism, the service life of seat can be extended.

Detailed description of the invention
As shown in Figure 1 and Figure 2, deployable and collapsible seat locking mechanism of the present utility model includes the seat frame for fixing seat and the backboard frame for stationary backplate, the first cross bar that described seat frame is parallel to each other by two vertical poles being parallel to each other 3 and two forms, the opposite sides of two vertical poles 3 is all machined with the rail groove passing through its overall length, the front end of two vertical poles 3 is mounted on the first capping, and one section, the rear end of two vertical poles 3 is all bent upwards in arc-shaped.Described backboard frame is the rectangular frame being formed by connecting by two montants 8 and two the second cross bars 6, spacing between being smaller than inside two vertical poles 3 between outside two montants 8, the outside of the neighbouring lower end of two montants 8 is mounted on roller, two rollers are respectively placed in the rail groove of corresponding vertical pole 3, and described backboard frame can be taken in into horizontal by rail groove and two rollers or decontrol into approximation setting shape.Lock banking stop 1 it is provided with between the rear inside of two vertical poles 3 to the corresponding montant 8 of backboard frame, one, the top of lock banking stop 1 is hinged on the rear inside of corresponding vertical pole 3 by bearing pin 2, it is connected with pull bar 4 between the other end, top of two lock banking stops 1, inside the lock banking stop 1 of adjacent rod 4 two ends junction point and between the adjacent back end of corresponding vertical pole 3, is all connected with extension spring 5.The most neighbouring middle of described lock banking stop 1 is all machined with lower convexity 1-1, and the outside of lower convexity 1-1 is all machined with the crotch 1-2 towards the bending of vertical pole 3 rear end.Two montants 8 are mounted on backing pin 7 adjacent to the outside of its lower end, and described backing pin 7 is all the most corresponding with corresponding crotch 1-2 and is all caught on by crotch 1-2.
When backboard frame income being the level of state, as long as hand-pulling pull bar 4 upwards to lift, while extension spring 5 is stretched, make lock banking stop 1 around the bearing pin 2 upwards back rotation of one, its top, until making hook 1-2 under lock banking stop 1 be separated with the backing pin 7 of backboard frame two montant 8 lower end outside, backboard frame can be taken in into horizontal.When backboard frame being decontroled in upright state, reverse operating above-mentioned steps.
