The specific embodiment
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only shows the formation relevant with the present invention.
As shown in Fig. 1-6, a kind of material that furls launches the safety gear of locating, the outer tube 2 and the rotating inner tube 4 being contained in outer tube 2 that comprise hollow, also comprise the revolving part that is arranged on inner tube 4 one end, can rotates with inner tube 4, and be located at fork 6 between outer tube 2 and revolving part.Fork 6 comprises the anchor shaft 62 being fixedly installed with respect to outer tube 2, and can rotate around anchor shaft 62, the body 64 of c-shaped or U-shaped, anchor shaft 62 places are also provided with and can control the retracing spring 66 that body 64 resets with respect to anchor shaft 62 rotations, a circumferential place of revolving part is provided with the first Access Division 82, and fork 6 is provided with the second Access Division 68 coordinating with the first Access Division 82.
The cross section profile integral body of outer tube 2 is D shape, and the sidewall of outer tube 2 offers for outwardly directed v notch v 22 of material 1 free end.From cross-wise direction, outer tube 2 is comprised of the first wall 24 of in-line and the second wall 26 of C shape, and one end of the second wall 26 and the first wall 24 join, and the other end and the first wall 24 keep gap, form breach 22.
Inner tube 4 is for the material 1 of reeling, and one end of inner tube 4 is coaxially provided as the cam 8 of revolving part, and cam 8 is contained in the opening of fork 6 bodies 64.The summit of the first Access Division 82 points to a side of cam 8 forward directions, and wherein forward direction is material 1 rotation direction with moving cam 8 while launching, otherwise is reverse directions.
Fork 6 bodies 64 are specifically included as the inner side that straight-bar portion 642 that anchor shaft 62 divided and bow portion 644, the second Access Divisions 68 are arranged on bow portion 644.More particularly, bow portion 644 is V-shaped on the whole, and its turning 65 is arc transition.Certainly bow portion 644 on the whole also can L-shaped or U-shaped, and turning is also arc transition.Straight-bar portion 642 is arranged in outer tube 2 corresponding to a side of breach 22, and termination 7 is flats and exposes outer tube 2 breach 22.The axis of anchor shaft 62 is parallel to the pivot center setting of inner tube 4, and when fork 6 bodies 64 turn over certain angle with respect to anchor shaft 62, retracing spring 66 can make fork 6 bodies 64 reset.
In outer tube 2, be also provided with a damper 9 between outer tube 2 and fork 6, damper 9 comprises the oblate cylindrical body 92 fixing with respect to outer tube 2, and the coaxial gear 94 that arranges, can rotate with respect to body 92.Fork 6 bow portion 644 outer ends are provided with the tooth 67 matching with gear 94, and rely on tooth 67 engagements to be connected on the gear 94 of damper 9.Retracing spring 66 is in the raw time, and the straight-bar portion 642 of fork 6 bodies 64 and bow portion 644 outer ends are resisted against respectively on first wall 24 and damper 9 of outer tube 2.When retracing spring 66 force fork 6 bodies 64 reset to cam 8 near time, damper 9 can slow down its process.
Cam 8, comprises circumferentially relative 84He slope, peak, slope paddy 86.The first Access Division 82 is arranged on the position of cam 8 slope paddy 86, and the first Access Division 82 is with respect to cam 8 outstanding forming radially, is mountain peak shape.One side waist of the first Access Division 82 is the card access surface 822 coordinating with the second Access Division 68, and card access surface 822 is by radially outwards departing from respect to omnibearing line J from inside to outside along cam 8.The card access surface 822 of the first Access Division 82 is ramped shaped, and card access surface 682 shapes of the second Access Division 68 match with it, makes the clamping of the two be more prone to also more stablize.
With regard to above-described embodiment, be applied to the principle of work that safety net illustrates safety gear of the present invention below.As shown in Figure 7, when initial, cam 8 engages mutually with fork 6, and safety gear is in locking state.During use, first push the straight-bar portion 642 being resisted against on outer tube 2 first walls 24 to second wall 26, thereby drive whole fork 6 body 64 forwards, bow portion 644 moves down, and has separated release, as shown in Figure 8 with cam 8.Now, can easily pull out safety net 3 on the one hand, fork 6 is subject to slowly rotating backward reset under the cooperation that acts on damper 9 of retracing spring 66 on the other hand, and in the process resetting at fork 6, safety net 3 band moving cam 8 forwards, the peak, slope 84 of cam 8 often turns around and fork 6 will be pushed away to cam 8, thereby guarantees in process that safety net 3 is drawn out, thereby fork 6 can not reset and hinders safety nets 3 with cam 8 clampings in advance and continued to pull out.And arrive target location when safety net 3 is drawn out, while stopping, fork 6 can slowly be got back to reference position under the impact of damper 9, the second Access Division 68 and first Access Division 82 of cam 8 of final fork 6 are fastened togather, as shown in Figure 9, now safety net 3 cannot continue to be drawn out, so safety net 3 can not stretch forward when being subject to impacting again, so can actv. resistance shelves alluvium 5 strike the steerman in the place ahead.
Above foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, related personnel can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on specification sheets, must determine technical scope according to claim scope.
