Abstract

A C-shaped hook relates to the technical field of lifting hooks and solves the problems that a chain with a square cross section is placed into the lifting hook to generate large stress and abrasion; the square chain is placed in the groove of the hook body, and the horizontal groove and the inclined groove are in contact with the plane of the square chain, so that the chain cannot be damaged; the width of the opening of the hook body is designed to improve the safety of the lifting hook; the bottom of the hook body is wholly horizontal and can be connected with a hanging strip.

Description

C-shaped hook

Technical Field

The utility model relates to a lifting hook especially relates to a C type hook.

Background

With the development of science and technology, chains for forest felling industry have also come to be updated, chains with circular cross sections are generally used in the prior art, many enterprises begin to use the chains with square cross sections, the yield strength of the chains with square cross sections is higher, the toughness is better, the service life is longer, the safety is higher, and the chain is very suitable for the forest felling industry. However, the lifting hook in the prior art is generally designed by matching with a chain with a circular section, the assembly surface is generally an arc surface, and the square section chain can generate large stress and abrasion when being put in, so that the advantage of the square section chain cannot be exerted.

Disclosure of Invention

In order to solve the problem, the utility model provides a C type hook provides the lifting hook of a better assembly with square cross section's chain. In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a C type hook, includes the coupler body, the coupler body set up to the C type, the whole horizontal structure that sets up in bottom of coupler body, the bottom of coupler body still is provided with the recess, the recess include horizontal groove and chute, the chute setting in the both sides of horizontal groove.

Further, the width of the opening of the hook body is set to be the width of the arc-shaped face of the square chain, the arc-shaped face transition is arranged between two sections of the square chain, the width of the opening of the hook body is consistent with the width of the opening of the hook body, the chain can be placed into the hook body, the chain cannot be separated easily, and the safety is improved.

Furthermore, the upper portion of the hook body is provided with a pin shaft hole and an assembling groove, so that the hook is convenient to hoist.

Further, a hook body identification groove is formed in the hook body.

Compared with the prior art, the utility model discloses following beneficial effect has: the square chain is placed in the groove of the hook body, and the horizontal groove and the inclined groove are in contact with the plane of the square chain, so that the chain cannot be damaged; the width of the opening of the hook body is designed to improve the safety of the lifting hook; the bottom of the hook body is wholly horizontal and can be connected with a hanging strip.

Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described with reference to fig. 1, fig. 2, fig. 3, fig. 4 and specific embodiments.

As shown in the attached

drawings

1, 2, 3 and 4, the C-shaped hook comprises a hook body 1, wherein the hook body 1 is of a C shape, the whole bottom of the hook body 1 is of a horizontal structure, a groove 2 is further formed in the bottom of the hook body 1, the groove 2 comprises a horizontal groove 3 and inclined grooves 4, and the inclined grooves 4 are formed in two sides of the horizontal groove 3.

Further, 5 width settings of opening part of coupler body 1 are the width of square chain arcwall face 6, and the arcwall face transition is between two sections of square chain, and the opening part width of coupler body is unanimous with it, can put into the chain, and the chain can not deviate from easily, has improved the security.

Furthermore, the upper part of the hook body 1 is provided with a pin shaft hole 7 and an assembling groove 8, so that the lifting is convenient.

Further, a hook mark groove 9 is arranged on the hook body 1.

The utility model discloses a theory of operation and working process as follows: the square chain enters the opening 5 of the hook body 1 through the arc-shaped surface 6, one chain is clamped into the groove 2, the plane of the chain is attached to the horizontal groove 3, the front chain and the rear chain are attached to the two sides of the horizontal groove 3, and the front chain and the rear chain are attached to the inclined groove 4, so that the square chain cannot be damaged.

Utilize technical scheme, or technical personnel in the field are in the utility model discloses under technical scheme's the inspiration, design similar technical scheme, and reach above-mentioned technological effect, all fall into the utility model discloses a protection scope.
