Abstract
The utility model relates to a machinery locking device with multiple steel balls gears type, which aim is to design a mechanical locking device for adjusting angles of the seat back having dispersal stress, uneasy wearing gears, small unlocking force, noiselessness, reliable locking, easy manufacture, low cost and bigger than 90 DEG angle adjusting range. A rocking arm is for drive the gears to rotate; a handle controls the steel balls to move along the peripheral hole of the disk component and to joint with the gear slots of the gears, and the steel balls can be locked tightly at any angle. The utility model is suitable for seats and couches for passengers in vehicles such as airplanes, automobiles, etc., and is suitable for adjusting and locking tightly angles of the backrest of driver seats.
Description
The utility model belongs to back of seat angular adjustment mechanical locking device.
Prior art mostly is to adopt the mechanical locking device of ratchet device, and tooth portion is stressed big, fragile, and unlocking force is big, use has noise.
The purpose of this utility model is a kind of stressed dispersion of design, and tooth portion is not easy to wear, and unlocking force is little, noiselessness, and reliable lock is easily made, and cost is low, and the angle modulation scope is greater than 90 ° back of seat angular adjustment mechanical locking device.
The utility model is to rotate by the rocking arm driven gear, utilizes handle control steel ball to move along the circumferential hole on the dish with the teeth groove of gear and fits, and it is locked at any use angle.
The utlity model has stressed dispersion, tooth portion is not easy to wear, unlocking force is little, noiselessness, reliable lock is easily made, cost is low, the angle modulation scope is greater than 90 ° advantage, is applicable to that vehicle occupants such as aircraft, automobile regulate locking with the backrest angle of seat and chaise longue, is specially adapted to chaufeur and takes advantage of seat.
Embodiment below in conjunction with accompanying drawing describes particular content of the present utility model in detail:
Accompanying drawing 1 is the part sectional view of locking state of the present utility model, and accompanying drawing 2 is the A--A section-drawing of accompanying drawing 1.Gear (9) can rotate in dish (7) around axle (8), dish (7) is anchored on lock (11), can not relatively rotate with axle (8), the web of dish (7) is along circumferentially having aperture and the identical several holes of steel ball (4) diameter, be illustrated as 4 holes, put a steel ball (4) in every hole, the major part of steel ball (4) is arranged in the hole of dish (7), fraction is positioned at the between cog of gear (9), and it is tangent with adjacent two flank profils, inner surface belt has the non-dead slot inside face of the outer shroud (10) of dead slot to compress steel ball (4), can not from dish (7) hole, overflow when making steel ball (4) stressed, steel ball this moment (4) can not relatively rotate dish (7) and gear (9), and this device is in locking state.When moving handle (5), outer shroud (10) circumferentially slides on dish (7) edge relatively, the part of steel ball is owing to the compressing of the flank of tooth enters the inside face dead slot of outer shroud (10), and gear this moment (9) can rotate dish (7) in around axle (8), and this device is in unlatching and adorns attitude.The stroke that limiting stopper (2) restriction handle (5) is moved, spring (6) is the pull back spring of handle (5), makes it be in locking dress attitude usually.
Rocking arm during use (1) top links to each other with seat back-rest framework with bolt, and the bottom links to each other with gear (9), and a stool skeleton of lock (11) and seat links to each other, and leans on the adjusting of the different use angles of realization back of seat behind control by handle (5) and the occupant.Clockwork spring (12) be behind backrest return power and the occupant by the time buffering, enclosing cover (3) be a Plastic Parts, in order to protect and to decorate this device.
Claims (3)
1, a kind of gear mechanism latching device is characterized in that adopting many steel balls (4), dish (7) and outer shroud (10) to constitute.
2, latching device as claimed in claim 1 is characterized in that the web of dish (7) has aperture and the identical several holes of steel ball (4) diameter along circumferentially designing, and puts a steel ball (4) in every hole, and the inside face design of outer shroud (10) has some dead slots.
3, as claim 1,2 described latching devices, it is characterized in that design has handle (5) and driven gear (9) that outer shroud (10) is circumferentially slided relative to dish (7) edge to rotate the rocking arm (1) that control steel ball (4) moves around axle (8) in the circumferential hole of dish (7).
