Abstract

The utility model discloses a novel anticreep couple, including the couple with connect the anticreep device on the couple, partially do not establish to first flange and second flange the both sides in couple hook groove, gets in touch the anticreep device and include a U type spare, forms two kinks after the both sides arm tip of U type spare is buckled, is provided with the briquetting between two kinks, is provided with the connecting axle between the arm of the both sides of U type spare, the cover that sets up is worn to establish by the connecting axle on the first flange of couple intraductal, and just the first flange of couple lies in the space in besieged city between connecting axle, U type spare base and the both sides arm, and the second flange of couple lies in outside the space, the base of U type spare is located the hook inslot of couple, and U type spare base has been pressed under briquetting self action of gravity and the second flange tightly contacts. The utility model has the advantages of simple structure and reasonable design, through add an anticreep device on current couple for after having caught hold of the heavy object with a hook, at the handling in -process, avoid the heavy object to follow the occurence of failure that comes off in the couple.

Description

A kind of disconnecting preventing hook

Technical field

The utility model relates to a kind of disconnecting preventing hook.

Background technology

As everyone knows, usually overhead traveling crane or electric block is provided with for suspension heavy weight in job shop, overhead traveling crane or electric block carry out hook by the hook that its lower end connects and are hung workpiece, in handling process, due to swing or the other factors of workpiece, workpiece easily comes off from hook, and causes the accident that the staff in workshop is injured or equipment is impaired to occur.At present, at the opening part of hook one catch is set and spring prevents coming off by hook workpiece although had, the catch in this structure and spring all easily damage, and catch is usually thinner, and anticreep effect is not fine.

Summary of the invention

In order to solve problems of the prior art, the purpose of this utility model is to provide a kind of disconnecting preventing hook, realizes existing hook after catching on weight by setting up an anti-drop device on existing hook, and weight can not come off in hook.

In order to realize foregoing invention object, the utility model adopts technical scheme as described below:

A kind of disconnecting preventing hook, the anti-drop device comprising hook and be connected on hook, the both sides of hook hook groove are set to the first rib and the second rib respectively, hook drop-proof device comprises one U-shaped, two kinks are formed after the two side arms end bending of U-shaped, briquetting is provided with between two kinks, adapter shaft is provided with between the two side arms of U-shaped, described adapter shaft is located in sleeve pipe that the first rib of hook is arranged, and the first rib of hook is positioned at adapter shaft, in U-shaped space of encircling a city between base and two side arms, second rib of hook is positioned at outside described space, the base of described U-shaped is positioned at the hook groove of hook, and U-shaped base has been pressed and the second rib close contact under the effect of briquetting self gravitation.

Owing to adopting technique scheme, the utility model adopts technical scheme as described below:

The utility model structure is simple, reasonable in design, and by setting up an anti-drop device on existing hook, after making hook hook weight, in handling process, the accident avoiding weight to come off in hook occurs.
