A binding device for adjusting the slack degree of the lace

Abstract

The invention discloses a binding device with a tying strap looseness degree adjustment function. The binding device comprises a binding device body, as well as a main tying strap with a draw hook and an auxiliary tying strap with a draw hook, wherein the binding device body comprises a base, a reel pivoted onto the base, ratchet wheels fixedly mounted at the two ends of the reel, and a wrench pivoted onto the reel; the ratchet wheels are located between the base and the wrench; an extending part is arranged at one end of the reel and is in screw connection with an internally-threaded part and a clamp nut; and one end surface of the internally-threaded part is clung to the outer side surface of the wrench or is close to the outer side surface of the wrench. According to the technical scheme, when objects bound by the binding device are relatively heavy or have high probability of falling down, the pressure between the end surface of the internally-threaded part and the outer side surface of the wrench is adjusted to ensure that the friction force between the end surface of the internally-threaded part and the outer side surface of the wrench is appropriate, so that the phenomenon that the bound objects suddenly become scattered or hit an operator is prevented.

Description

technical field [0001] The invention relates to the technical field of hardware tools, in particular to a binding device. Background technique [0002] Binders are widely used in daily life, and their types are various. figure 1 The binder shown is one of them, and the binder includes a binder main body 90, a main tether 71 with a draw hook 80 and a secondary tether 72, wherein the draw hook 80 is generally in the shape of an "8" and includes a draw hook 80. With attachment loop 81 and shackle 82. [0003] Such as figure 2 As shown, the binder main body 90 includes a base 92, a reel 91 pivotally connected to the base 92, a ratchet 94 fixedly installed at both ends of the reel 91, a wrench 93 pivotally connected to the reel 91, and the rear end of the main tether 71 is wound around Set on the reel 91 of the binder, the secondary tether 72 is fixedly connected with the beam 921 of the base 92 . [0004] The base 92 is provided with a first elastic card 922, and the wrench...

AI Technical Summary

Problems solved by technology

If the object bound by the binding device is heavy, or easy to roll off, when the degree of freedom of rotation of the reel 91 is suddenly changed from being restricted to being unrestricted, the bound object may be uncontrolled like a wild horse running free, and may All of a sudden become scattered or hurt the operator
