Detailed Description
Specific embodiments of the present utility model will be further described below with reference to the accompanying drawings. Wherein like parts are designated by like reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and the words "inner" and "outer" refer to directions toward or away from, respectively, the geometric center of a particular component.
In order to make the contents of the present utility model more clearly understood, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
As shown in fig. 1 to 2, the rope tightener,
The rope 70 is used for binding, and one end of the rope 70 is provided with a rope sleeve 71.
Referring to fig. 4, the outer circumferential wall of the rope reel 80 is fixedly connected to one end of the rope 70 remote from the rope hitch 71; spool shafts 81 are fixedly provided at both ends of the rope reel 80.
The bracket 90 is rotatably connected to the two spool shafts 81 of the rope reel 80.
The ratchet wheel 40 is fixedly connected with the rope drum 80 coaxially.
A pawl assembly 50 is defined on the bracket 90, the pawl assembly 50 and the ratchet 40 forming a ratchet-pawl mechanism; that is, the pawl assembly 50 defines that the ratchet 40 can only rotate in one direction; specifically, the pawl assembly 50 includes a pawl 51, a support member 52, a pawl rotation shaft 53, and a torsion spring; the supporting part 52 is fixedly connected with the bracket 90, and the pawl rotating shaft 53 is limited with the supporting part 52 and the bracket 90; the pawl 51 is rotated by a pawl rotation shaft 53; a torsion spring (not shown) is sleeved on the pawl rotating shaft 53, and the elasticity of the torsion spring acts on the pawl 51, so that the end of the pawl 51 abuts against the tooth slot 41 of the ratchet 40.
Referring to fig. 2 and 3, a movable opening 102 is formed in the rope tightening handle 100, the movable opening 102 is movably sleeved on the periphery of the spool shaft 81, and a stirring tooth 101 matched with the tooth slot 41 of the ratchet wheel 40 is fixedly arranged on the rope tightening handle 100; the relative positions of the movable opening 102 of the rope tightening handle 100 and the spool shaft 81 are adjusted, and the poking teeth 101 and the tooth grooves 41 are meshed and separated from each other; referring to fig. 2, a rope tightening process a, namely, a poking tooth 101 of a rope tightening handle 100 is positioned in a tooth slot 41, the rope tightening handle 100 is rotated to poke a ratchet wheel 40 to rotate unidirectionally by the poking tooth 101, and meanwhile, a rope 70 is wound unidirectionally by a rope winding drum 80; the non-tightening state b, the tightening handle 100 is adjusted back and forth, namely, the position of the tightening handle 100 is moved, so that the poking teeth 101 are separated from the tooth grooves 41, and the tightening handle 100 is rotated in the reverse direction of tightening, namely, the tightening handle 100 is reset; the process a, b is repeated reciprocally, and the rope 70 is wound up a plurality of times.
