Description

Can carry out the chain suspension hook of stage casing serial connection

Technical field

The utility model relates to the chain suspension hook, particularly can carry out the chain suspension hook of stage casing serial connection.

Background technology

Main and the continuous reel chain of suspension hook is connected in series use, promptly does the fastener location at the rear of chain, with lifting or towing weight.And behind the hook weight, if again in the chain stage casing and connect other hook body, with auxiliary hook or increase hook purposes, or increase when receiving other chain, traditional practice is to increase a U type hook or the two-way shackle that can movable remain silent in addition, this U type hook or two-way shackle is pre-aligned behind the selected position of chain, and the back segment mouth of hook by this U type hook or two-way shackle again anchors the position to an end hook of hook body or chain; So, except having increased the inconvenience and burden that to prepare U type hook or two-way shackle in advance; Mainly be this U type hook or two-way shackle in advance after the fastener location, the avidity coupler body that it still belongs to rocking property so causes the situation of rocking in inconvenience on clasp joint and the use, and impracticable.

Summary of the invention

Main purpose of the present utility model is to provide a kind of chain suspension hook that carries out the stage casing serial connection.

The chain suspension hook that carries out stage casing serial connection of the present utility model, main system is made of hook body and the latch part that is positioned at above the hook body; It is characterized in that: described latch part is the U type, is provided with the groove that places that a side runs through on these U type both sides, is disposed with spring and active pin in this places groove; Described latch part is provided with jack, and this jack is connected with the above-mentioned groove that places, and a latch inserts above-mentioned jack described active pin is positioned; Described active pin is provided with short slot, and under normal conditions, described short slot is hidden in the sidewall of described latch part; A corresponding side with above-mentioned short slot on the U of described latch part type inner face is provided with a semicircle groove of striding the both sides of the U type of establishing described latch part; Push described spring by pushing described active pin, described short slot is exposed at U type opening part, the straight order chain link of chain can be brought the transverse mesh chain ring of its bottom in the described semicircle groove of described latch part through the position of described short slot; Described active pin is positioned at chain in the semicircle groove by the restoring force of described spring.

Can overcome rocking in inconvenience on the hook joint and the use by above-mentioned structure; Therefore, in the time of can preventing that not only hanging weight moves, the danger situation that causes chain to be deviate from because of the thing collision takes place; And because of suspension hook can be for chain with arbitrary order chain link to being combined in described latch part, and reach fixing simple and easy, and safe, again the effect of reliable location.

The specific embodiment

Followingly the specific embodiment of the chain that carries out stage casing serial connection of the present utility model with suspension hook described with reference to accompanying drawing.As shown in Figure 1 and Figure 2, the chain that carries out stage casing serial connection of the present utility model is made of hook body 2 and the latch part 3 that is positioned at hook body 2 tops with suspension hook system; Wherein:

This latch part 3 is the U type, because the width limitations of U type opening 31, can avoid because the chain of misuse different size causes dangerous situation to take place, latch part 3 both sides are provided with that a side runs through places groove 32, and this places and is disposed with spring 33 (as Fig. 4, shown in Figure 5) and active pin 34 in the groove 32; Latch part 3 is provided with jack P ', this jack P ' with place groove 33 and be connected so that active pin 34 is plugged the location, spring 33 and active pin 34 can not dropped from latch part 3 by latch P; Active pin 34 is provided with short slot 341, and this short slot 341 is hidden in the sidewall of latch part 3 under normal conditions; On the U of latch part 3 type inner face,, be provided with one and stride the semicircle groove 35 of establishing latch part 3U type both sides with short slot 341 corresponding sides; When chain S clip is in U type opening, by pushing active pin 34 extrusion springs 33, short slot 341 is exposed at U type opening 31, the straight order chain link S1 of chain can be by the position of short slot 341, the transverse mesh chain ring S2 of its bottom is taken advantage of a situation in the semicircle groove 35 of bringing latch part into, decontrol active pin 34, because the restoring force of spring, active pin 34 returns to the home position, and short slot 341 is hidden in the sidewall of latch part 3 again.In this way, chain S reliably can be positioned in the semicircle groove 35.In addition, the side that active pin 34 protrudes out on latch part 3 is provided with protection edge 36, and this protection edge can prevent 34 rounds impact failures of active pin or deviate from, rocks.

Come compression spring 33 by pushing active pin 34, short slot 341 is exposed at U type opening part, the straight order chain link S1 of chain can be through the position of short slot 341, and the transverse mesh chain ring S2 of its bottom is brought in the semicircle groove 35 of latch part 3; Active pin 34 is positioned at chain S in the semicircle groove 35 by the restoring force of spring 33.

It is assembled and makes flowing mode, as Fig. 3, shown in Figure 4, the latch P that at first will be plugged between latch part 3 and the active pin 34 extracts, again chain S is desired the chain link of clip to being combined in latch part 3, push the end that active pin 34 exposes, so that compression spring 33, make active pin 3 be hidden in the interior short slot of latch part sidewall 341 outer U type opening 31 places (shown in Fig. 3 A and Fig. 4 A) that are exposed at latch part 3 originally, so that straight order chain link S1 can be through short slot 341, the transverse mesh chain ring S2 that will be positioned at this straight order chain link S1 bottom brings the semicircle groove 35 of latch part into, and make the end face (as Fig. 3 B shown in) of the lucky contact of transverse mesh chain ring S2 end face at semicircle groove 35, decontrol active pin 34 again, because the restoring force of spring 33, the short slot 341 of active pin is hidden in latch part 3 sidewalls once more.In this way, in the semicircle groove 35 of latch part 3 (Fig. 4 B) inserts latch P between latch part 3 and the active pin 34 afterwards again with chain S clip, deviates to prevent chain.

As shown in Figure 5, suspension hook is by establishing semicircle groove 35 in latch part 3, and latch part 3 lateral margins have protruded out active pin 34, active pin 34 is provided with the architectural feature of breach 341, make when being needed orientation angle by hanging piece, can adjust the position of suspension hook and chain S fastener location according to demand, and can finish and use hook body group to need the above just achievable work of two kinds of assemblies at least in the past; Therefore, in the time of can preventing that not only hanging weight moves, the danger situation that causes chain S to deviate from because of the thing collision takes place; And because of suspension hook can be for chain S with arbitrary order chain link to being combined in latch part 3, and reach fixing simple and easy, and safe, again the effect of reliable location.

In sum, the utility model can reach every requirement of goal of the invention really, and significantly promote the practical effect of traditional product by its its specific structure feature, has obviously met the establishment important document of utility model patent.
