Abstract

A rope tightener belongs to the field of rope binding tools in transportation. The traditional rope tighteners have a common defect that bulky cargoes cannot be bound tightly at a time, so that after a vehicle travels a certain distance, a tightened vehicle sealing rope becomes undone and loses the goods fixation function. Aimed at overcoming the design defect of the traditional rope tighteners, the utility model provides a rope tightener with a self-tightening function, which can keep the vehicle sealing rope being tightened at all times.

Description

A kind of boomer

Technical field

The present invention relates to a kind of boomer, belong to the field of tool that is used for the rope binding in the communications and transportation.

Background technology

Existing 40 more than of the patented technology of relevant boomer, but from technological layer, a common defective is all arranged, that is exactly when bundling fluffy bulky cargo, existing boomer all can not once bind, after car travelled the stretch journey, it is lax that the envelope car rope of originally tightening just becomes, and lost the function of restraint of loads; Produce the gently then missing package of result of this phenomenon, heavy then make goods centre-of gravity shift cause overturning.So, brake again after have to stopping for this situation driver, this has brought a lot of inconvenience to people, has also influenced the safety of transportation and the raising of efficient simultaneously.

Summary of the invention

Purpose of the present invention is to remedy the design deficiency of above-mentioned boomer, and a kind of boomer with function of self-tightening is provided.It can make the rope of envelope car be in tensioned state all the time, its principle of work: be to utilize the elasticity accumulation of energy of roll bending spring to strain rope.Its structure is made up of support, rope hook, rope roll, roll bending spring, rope roll axle, Positioning Gear, location tooth bar and boosting-rod; Rope roll is installed in support, the rope roll axle is installed in rope roll, the roll bending spring is installed between rope roll and rope roll axle, (the roll bending spring rolls with the rubber-like steel disc and forms) roll bending spring is wrapped on the rope roll axle, its two ends are separately fixed on the inboard and rope roll axle of rope roll, and the two ends of rope roll axle are fixed on the support and can rotate freely in support; At an end installing and locating gear of rope roll axle, installing and locating tooth bar above Positioning Gear, an end of location tooth bar is fixed on the support with pivot pin, and can be up and down around pivot pin.Be respectively equipped with the tooth of meshing acute angle shape mutually on Positioning Gear and location tooth bar, when making stationary rack and Positioning Gear mutually meshing, rope roll can only rotate to a direction, thereby rope roll is played the role of positioning.The other end at the rope roll axle is provided with hole, inserts boosting-rod during for the rotation boomer and uses.

The specific embodiment

Fig. 2, boomer B are to lateral plan Fig. 4, location tooth bar front view

1, support, 2, rope hook, 3, rope roll, 4, roll bending spring, 5, rope roll axle, 6, Positioning Gear, 7, location tooth bar, 8, pivot pin, 9, hole, 10, boosting-rod.

Shown in Fig. 1,2,3,4, rope roll 3 is installed in support 1, rope roll axle 5 is installed in rope roll 3, roll bending spring 4 is installed between rope roll 3 and rope roll axle 5, roll bending spring 4 is wrapped on the rope roll axle 5, its two ends are separately fixed on the inboard and rope roll axle 5 of rope roll 3, and the two ends of rope roll axle 5 are fixed on the support 1 and can be in support rotate freely in 1; At an end installing and locating gear 6 of rope roll axle 5, installing and locating tooth bar 7 above Positioning Gear 6, an end of location tooth bar 7 is fixed on the support 1 with pivot pin 8, and can be up and down around pivot pin 8.Be respectively equipped with the tooth of meshing acute angle shape mutually on Positioning Gear 6 and location tooth bar 7, when making stationary rack 7 and Positioning Gear 6 mutually meshing, rope roll 3 can only rotate (direction shown in Fig. 2 arrow) to a direction, thereby rope roll 3 is played the role of positioning.The other end at rope roll axle 5 is provided with hole 9, inserts boosting-rod 10 during for the rotation boomer and uses.

During use, whole boomer is installed in the both sides of compartment collar tie beam by support 1, envelope car rope is hung on the rope hook 2, screw rope roll axle 5 with boosting-rod 10, rope roll axle 5 drives rope roll 3 rotations by roll bending spring 4, and rope is wrapped on the rope roll 3, when rope is tightened up, roll bending spring 4 is the accumulation of energy by the deformation of self also, and when the rope of envelope car when fluffing, the roll bending spring will drive that rope roll 3 rotates voluntarily and with rope stretch.
