Abstract
The utility model discloses a kind of portable wallboard digitlization pretensioner systems, puller strap one end of fixing covering is penetrated this puller strap jack by the axis of guide by native system, pull tension handle to drive ratchet to rotate, ratchet drives rotating shaft to rotate, and is wound around puller strap; Ratchet retaining plate synchronous operation while tension handle drives ratchet and rotating shaft to carry out rotating, ratchet retaining plate, by back-moving spring, prevents ratchet backwards rotation, thus guarantees that rotating shaft can only one-way movement, strains puller strap; Rotating shaft is provided with driven button, and control the connection of rotating shaft and rotary handle, rotary handle is provided with handle; Press driven button, start arrangement of clutch, rotary handle is connected with rotating shaft, and draw-out handle also rotates, and handle drives rotary handle motion, and rotary handle makes rotating shaft backwards rotation, realizes the folding and unfolding of puller strap.
Description
Technical field
The utility model belongs to a kind of pretensioner systems, particularly a kind of pretension tension system for fixing covering in aircraft skin processing with puller strap.
Background technology
During aircraft skin drawing and forming, need to be tied up by covering on mould tire and tighten with puller strap, during to ensure that skin drawing is shaping, covering and mould tire are effectively fitted, and traditional covering is fixing mainly by artificial operation in frock, not only danger and also efficiency low; Also have and adopt pulley or stir thick stick tension, but complex operation, inconvenient, poor reliability.
Summary of the invention
The utility model object is to provide the portable wallboard digitlization pretensioner systems that a kind of volume is little, lightweight, handled easily uses.For achieving the above object, the utility model takes following technical proposals:
Portable wallboard digitlization pretensioner systems described in the utility model comprises rotating shaft, the axis of guide, spline plate handle, tension handle, handle handle reset wind spring, ratchet, driven button, rotary handle, handle, ratchet retaining sheet reset spring, ratchet retaining plate and base; Described tension handle, ratchet and rotating shaft are fixed on the axis of guide, and be installed on base, in tension handle both sides, elongated slot is set, spline plate handle two ends to be fixed in the elongated slot of both sides and and between rotating shaft, handle handle reset wind spring be set unlock straining handle, rotating shaft is provided with driven button, this driven button presses rear startup clutch apparatus, the connection of rotation-controlled axle and rotary handle.Pull tension handle, ratchet can be driven to rotate, thus driven rotary axle rotates, the puller strap treating tension is tightened, rotating shaft is provided with ratchet retaining sheet reset spring, and ratchet retaining sheet reset spring is connected with ratchet retaining plate, prevents ratchet backwards rotation, thus guarantee that rotating shaft can only one-way movement, puller strap is strained.
The utility model structure is simple, easy and simple to handle, use safety.During use, puller strap is fixed on the jack at the center of rotating shaft, rotating shaft is driven to rotate by ratchet after pulling tension handle, coordinated by ratchet and retaining plate back-moving spring and prevent reversion, until puller strap tension, easy and simple to handle, substantially increase the security of efficiency that covering fixes and frock operation.

Wherein: 1, rotating shaft; 2, the axis of guide; 3, spline plate handle; 4, handle is strained; 5, handle handle reset wind spring; 6, ratchet; 7, driven button; 8, rotary handle; 9, handle; 10, base; 11, ratchet retaining sheet reset spring; 12, ratchet retaining plate; 13, puller strap.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.See Fig. 1 to Fig. 3, this system mainly comprises rotating shaft 1, the axis of guide 2, spline plate handle 3, tension handle 4, handle handle reset wind spring 5, ratchet 6, driven button 7, rotary handle 8, handle 9 and base 10, ratchet retaining sheet reset spring 11 and ratchet retaining plate 12.Wherein, rotating shaft 1 center is provided with puller strap jack; Tension handle 4, ratchet 6 and rotating shaft 1 to be fixed on the axis of guide 2, and to be installed on base 10; Pull tension handle 4 that ratchet 6 can be driven to rotate, thus driven rotary axle 1 rotates, and then the puller strap 13 of fixing covering is wound around, ratchet retaining plate 12 synchronous operation while tension handle 4 drives ratchet 6 and rotating shaft 1 to carry out rotating, ratchet retaining plate 12 is by ratchet retaining sheet reset spring 11, prevent ratchet 6 backwards rotation, thus guarantee that rotating shaft 1 can only one-way movement, puller strap 13 is strained.
Tension handle 4 both sides arrange elongated slot, the two ends of spline plate handle 3 are fixed in the elongated slot of both sides and also and between rotating shaft 1 handle handle reset wind spring 5 is set, when upwards mentioning spline plate handle 3, handle handle reset wind spring 5 unlocks tension handle 4, tension handle 4 can pull, and rotating shaft 1 is provided with driven button 7, after pressing this key, start clutch apparatus, control the connection of rotating shaft 1 and rotary handle 8.Rotary handle 8 is arranged handle 9, for controlling rotary handle 8.
During use, puller strap 13 one end is penetrated this puller strap jack by the axis of guide 2, puller strap 13 is derived along the axis of guide 2, back and forth pull tension handle 4 after pulling spline plate handle 3, until puller strap 13 is strained.After tension to be done, during dismounting puller strap 13, press driven button 7, start arrangement of clutch, rotary handle 8 is connected with rotating shaft 1, and draw-out handle 9 also rotates, handle 9 driven rotary handle 8 moves, rotary handle 8 makes rotating shaft 1 backwards rotation, after puller strap 13 unclamps, it is taken out from puller strap jack.
It is evident that, above description and record be only citing instead of in order to limit disclosure of the present utility model, application or use.Although described in an embodiment and be described in the drawings embodiment, but the utility model do not limit by describe in embodiment as the optimal mode thought at present to implement the specific examples of instruction of the present utility model, scope of the present utility model will comprise any embodiment of description and the appended claim fallen into above.
