Embodiment 1
[0029] Figure 1 to image 3 As shown, the retractor of the present embodiment includes a housing 1, a center shaft 11, a driven gear 2 that transmits power from a driving gear 13, a reel 10 and a hoisting rope 9, the driven gear 2 and the reel 10 is connected and mounted on the central shaft 11 in series, and one end of the lifting rope 9 is connected with the reel 10 and the other end is connected with a traction point of the account body; When significantly exceeding the maximum normal tension of the hoisting rope 9 during the lifting of the tent body, the overload separation device of the power coupling and the braking device that prevents the passive reversing of the reel in the tractor will be separated. The overload separation device of this embodiment is made up of bolt wheel 6, constant pressure spring 5, protruding bolt 4, internal gear 7; Bolt wheel 6 is coaxially fixedly connected with driven gear 2 and inserted into the inner wall of internal gear 7, and its outer ...
Embodiment 2
[0032] As shown in Figure 4, Figure 5 As shown, the present embodiment improves the braking device on the basis of the first embodiment. The braking device consists of a braking chainring 23, a braking tooth 25, a pin 24, a spline shaft 20, an advancing and retreating screw rod 19, and a fixing nut. 18. The active toothed disc 21, the screw spring 17, and the passive toothed disc 22 are composed; the spline shaft 20 is connected with the internal gear 7, and its central hole is matched with the central shaft 11; The disc 22 is fixedly connected with the reel 10, the central hole of the advance and retreat screw 19 is a flower hole matched with the spline shaft 20, the screw spring 17, the advance and retreat screw 19, and the driving tooth disc 21 are sequentially mounted on the spline shaft 20, and the fixed nut 18 is fixed on the housing 1, the screw hole of the fixing nut 18 is screwed in by the advance and retreat screw rod 19, and the thread of the fix nut 18 is to make ...
Embodiment 3
[0035] Such as Figure 6 , Figure 7 As shown, the braking device of this embodiment adopts the method of technical solution 7, and its structure and working principle are not repeated as described in the second embodiment. Connected brake tooth chute 24.1 and the brake tooth 25.1 that cooperates with chute, its groove will face the inwall of housing 1, and the bottom of groove will have the stopper that stops brake tooth 25.1 and can not fall out.
[0036] The overload separation device of this embodiment adopts the method of technical measure 4. One end of the bolt wheel 6 of the overload separation device has an axial hole that cooperates with the central shaft 11, and the other end has a guide hole 6.3, and the bolt hole 6.2 runs through the guide hole 6.3. In the middle of the hole 6.2 there is an axial pressure regulating screw hole 14 penetrating through the end face of the bolt wheel 6, and an axial guide rail 6.4 protrudes from the hole wall of the guide hole 6.3; T...
