Abstract

The utility model discloses an improved eye-shaped sliding hook. The eye-shaped sliding hook comprises a lifting hook main body (1), wherein an annular hole (2) is formed in the upper part of the lifting hook main body (1) to form an eye ring (3); the eye-shaped sliding hook is characterized in that the ring wall of the eye ring (3) is an oblate ring; the cross-sectional shape of the eye ring consists of two parallel straight lines and two semi-arcs. The improved eye-shaped sliding hook is simple in structure, convenient to use, high in load, high in safety, and high in sliding hook strength, and is suitable to be used in the places with high load force.

Description

Improved type ocular form Slip Hook

Technical field

The utility model relates to suspension hook, is specifically related to a kind of improved type ocular form Slip Hook.

Background technology

As everyone knows, in hoisting operation process, often adopt suspension hook, especially ocular form Slip Hook, Slip Hook is used need to coordinate the riggings such as loop chain, butterfly button, and the eye thimble portion of ocular form Slip Hook is round section conventionally, its round section is long-pending little, during work, contact surface is some contact, and reciprocating friction reduces intensity, causes flexural deformation in the situation that not reaching appointment working load number of times, severe patient fracture, to the great hidden danger of life security presence.

Summary of the invention

The purpose of this utility model is: a kind of improved type ocular form Slip Hook is provided, and simple in structure, easy to use, load is large, safe, improves Slip Hook intensity, is applicable to the place that loading force is higher.

Technical solution of the present utility model is: this ocular form Slip Hook comprises main hook part, and the open loop hole, top of main hook part forms eye thimble, it is characterized in that: the ring wall of eye thimble is oblate ring, and its cross sectional shape adds two and half arcs by two parallel straight lines and forms.

Wherein, the bilateral symmetry of the main hook part below eye thimble is established convex type draw-in groove, on draw-in groove through spring, screw, nut installing card jam plate.

The utlity model has following advantage: 1, the ring wall of eye thimble is oblate ring, its cross sectional shape adds two and half arcs by two parallel straight lines and forms, and has increased the sectional area of eye thimble ring wall, has increased the contact surface that the eye thimble portion of Slip Hook matches with loop chain, protection loop chain, thus load performance improved; 2, draw-in groove is positioned at eye thimble below bilateral symmetry projection, when lug latch board is opened, can keep original A/F, easy to operate.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the ring wall schematic cross-section of the eye thimble of Fig. 1.

Fig. 3 is that the eye thimble ring wall of Fig. 1 coordinates schematic diagram with loop chain.

Fig. 4 is that the eye thimble ring wall of existing suspension hook coordinates schematic diagram with loop chain.

Fig. 5 contrasts schematic diagram for eye thimble ring wall before and after improving coordinates with loop chain.

In figure: 1 main hook part, 2 annular distances, 3 eye thimbles, 4 draw-in grooves, 5 springs, 6 screws, 7 nuts, 8 lug latch boards.

The specific embodiment

As Figure 1-3, this ocular form Slip Hook comprises main hook part 1, and the open loop hole, top 2 of main hook part 1 forms eye thimble 3, it is characterized in that: the ring wall of eye thimble 3 is oblate ring, and its cross sectional shape adds two and half arcs by two parallel straight lines and forms.

Wherein, the bilateral symmetry of the main hook part 1 below eye thimble 3 is established convex type draw-in groove 4, on draw-in groove 4 through spring 5, screw 6, nut 7 installing card jam plates 8.

Claims

1. improved type ocular form Slip Hook, this ocular form Slip Hook comprises main hook part (1), the open loop hole, top (2) of main hook part (1) forms eye thimble (3), it is characterized in that: the ring wall of eye thimble (3) is oblate ring, and its cross sectional shape adds two and half arcs by two parallel straight lines and forms; The bilateral symmetry of the main hook part (1) below eye thimble (2) is established convex type draw-in groove (4), and draw-in groove (4) is upper through spring (5), screw (6), nut (7) installing card jam plate (8).
