Abstract

The utility model is a hook top-ring fixing element, consisting of a hook-shaped body and a suspension ring fixed above the hook-shaped body. A locking part protrudes from the top of the hook-shaped body and the locking part is provided with a penetrating hole; the suspension ring is arranged on the locking part of the hook-shaped body and a screw cap is arranged on the suspension ring to make the locking part protrude from the top of the screw cap; a block with radioactive limit ditch protrudes from the top of the screw cap and the penetrating hole of the locking part is right against the limit ditch of the screw cap so as to provide a spring pin of same length and diameter with the block for penetrating; the spring pin protruding out of the locking part is right arranged on the edge of the screw cap so as to integrate the suspension ring and the hook-shaped body; in addition, the fixing mode is that the spring pin penetrates the penetrating hole of the hook-shaped body and the limit ditch of the screw cap, thus omitting the riveting process by a riveting machine and achieve simple fixing effect.

Description

A kind of coupler body apical ring fixed component

Technical field

The utility model relates to coupler body apical ring fixation arrangement, particularly a kind of coupler body apical ring fixed component.

Background technique

Existing coupler body apical ring fixation arrangement sees also shown in Figure 4ly, is made of hook body 2 and the suspension ring 3 that is fixed on hook body 2 tops; Wherein, this hook body top protrudes out the latch part 11A of a tool helicoid, and latch part 11 tops projection one fixed block 112; These suspension ring 2 bottom surface tools one wear hole 21, and wearing hole 21 is set on the latch part 11A of hook body, be inserted on the latch part 11A by suspension ring 2 tops with nut 3A again, and make the fixed block 112 of latch part protrude out nut 3A top, cooperate again with riveting machine pressing and fixing piece 112, and suspension ring 2 is fixed on hook body 1 top.But should structure if the suspention position of suspension ring is too little, then desire to be difficult for, and if the body of suspension ring is too big or overweight with the riveting machine riveted, its desire cooperates riveting machine riveted also quite difficult, can cause the difficulty in its processing.

Summary of the invention

The purpose of the utility model design is that a kind of coupler body apical ring fixed component that reaches simple and easy fixed effect with the process of riveting machine riveted of saving is provided for the defective that overcomes prior art.

The suspension ring that the coupler body apical ring fixed component of the utility model design protrudes out the hook body of latch part by the top and is fixed on hook body latch part top is constituted; And the latch part of described hook body protrudes out the suspension ring top; Wherein: this hook body is provided with an inserting hole that runs through on latch part; After described suspension ring is inserted in the latch part of hook body, be engaged in latch part and be provided with a nut that is inserted in, the nut top protrudes out the less block of a diameter, and this block is provided with radial position-limited groove, and makes that the inserting hole on the latch part is just involutory in the position-limited groove of nut; The spring pin that one length is identical with the block diameter is passed through by position-limited groove, and penetrate the inserting hole of latch part, position-limited groove by the latch part the other end stretches out, and makes that protrude out the outer spring pin of latch part strides on the orle that is against nut, is integral and really suspension ring and hook body are set firmly.

The coupler body apical ring fixed component of the utility model design can also comprise that the described length that is plugged in the spring pin on the nut is equal to the diameter of nut block, spring pin rod edge after plugging together can not exposed, to avoid spring pin really because of colliding often and screw cap-falling.

Weight that the coupler body apical ring fixed component of the utility model design presses down with himself and nut and suspension ring are closely affixed, make it have certain fixed effect; And, with the orientation type that spring pin passes hook body and nut, can save with the process of riveting machine riveted and reach simple and easy fixing effect.

Further describe the purpose of this utility model, structural feature and practicability below in conjunction with drawings and Examples.

Description of drawings

The three-dimensional combination figure of the coupler body apical ring fixed component that Fig. 2 designs for the utility model.

The plane cut-away view of the coupler body apical ring fixed component that Fig. 3 designs for the utility model.

Fig. 4 is the flat assembly drawing of existing coupler body fixed component.

Wherein, each label is expressed as respectively described in the figure:

1 is the hook body; 11 is latch part; 111 is inserting hole; 11A is a latch part; 112 is fixed block; 2 is suspension ring; 21 for wearing the hole; 3 is nut; 31 is block; 311 is position-limited groove; 3A is a nut; 4 is spring pin.

Embodiment

See also Fig. 1, shown in Figure 2, can know and understand structural form of the present utility model, the utility model is made of hook body 1 and the suspension ring 2 that is fixed on hook body 1 top; Wherein:

This hook body 1 top protrudes out the latch part 11 of a tool helicoid, and establishes the inserting hole 111 of a penetration state on the latch part 11;

These suspension ring 2 bottom surfaces are provided with and wear hole 21, and wear hole 21 and be set on the latch part 11 of hook body 1, and make latch part 11 protrude out suspension ring 2 tops;

After suspension ring 2 is inserted in the latch part 11 of hook body again, be engaged in and be inserted in a nut 3 on the latch part 11 again, these nut 3 tops protrude out the block 31 of a diameter less than nut 3, and block 31 is provided with radial position-limited groove 311, and makes that the inserting hole 111 on the latch part is proper on the position-limited groove 311 that is combined in nut.

Cooperate again with the length spring pin 4 identical and pass through by position-limited groove 311 with block 31 diameters, and penetrate the inserting hole 111 of latch part 11, and stretch out by the position-limited groove 311 of latch part 11 the other ends, make that protruding out latch part 11 outer spring pin 4 can stride on the orle that is against nut 3, and really suspension ring 2 and hook body 1 are set firmly and be integral.

Please cooperate again consult shown in Figure 3, hook body 1 is provided with the latch part 11 of establishing for nut 3 locks on the top, and latch part 11 is provided with an inserting hole that runs through 111, and the position-limited groove 311 on the block of cooperation nut 3, and position-limited groove 311 just and inserting hole 111 involutory, after providing spring pin 4 to wear, spring pin 4 can be striden on the orle that is against nut 3, and suspension ring 2 is fixed on hook body 1 top; The length of spring pin 4 is equal to the diameter of nut block 31 again, and the spring pin 4 bar edge after plugging together can not exposed, and comes off with nut 3 because of collision often to avoid spring pin 4 really.

Like this, because of hook body 1 and suspension ring 2 wear the location with spring pin 4, and spring pin 4 just is crossed on the form on nut 3 orles, makes that weight that hook body 1 presses down with himself and nut 3 and suspension ring 2 are closely affixed, makes it have certain fixed effect; And, with the orientation type that spring pin 4 passes hook body 1 and nut 2, can save process with the riveting machine riveted, make its means of fixation simple and convenient.
