Abstract
The invention discloses a portable buffering lifting hook. The portable buffering lifting hook comprises a connection rod and lifting hooks, wherein a sleeve is arranged among the connection rod and the lifting hooks; the lifting hooks are symmetrically arranged at the both sides of the sleeve; the lifting hooks are connected with the sleeve through pin shafts; tension springs are arranged between the two lifting hooks; the tension springs are symmetrically arranged at the tops of the lifting hooks; a thread is arranged on the connection rod; a nut is arranged at the lower part the sleeve. The portable buffering lifting hook disclosed by the invention is reasonable in structural design, capable of buffering a lifted object through the action of the tension springs, and capable of adjusting the up-and-down heights of the lifting hooks to adapt to the use needs in different environments, and thus the application range is expanded and popularization and use are facilitated.
Description
Technical field
The present invention relates to mechanical field, especially relate to a kind of hand-held design buffering suspension hook.
Background technology
Traditional suspension hook does not have buffer action, and when lifting by crane some tight instruments or fragile, the impulsive force of lifting easily produces injury to instrument or fragile, causes unnecessary loss.
Summary of the invention
The present invention solves the problem that current suspension hook does not have buffer action, for herein is provided a kind of hand-held design buffering suspension hook, comprise pipe link and suspension hook, be provided with sleeve between described pipe link and suspension hook, described suspension hook is symmetricly set on the both sides of sleeve, passes through pinned connection between described suspension hook and sleeve, extension spring is provided with between described two suspension hooks, described extension spring is symmetricly set on suspension hook tip position, and described pipe link is provided with screw thread, is provided with nut below described sleeve.
The invention has the beneficial effects as follows: reasonable in design of the present invention, can be cushioned lifting article by the effect of extension spring, and can the upper-lower height of adjusting lift hook, adapt to the use needs of varying environment, expand Applicable scope, be easy to promote the use of.
Accompanying drawing explanation
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
Fig. 1 is schematic front view of the present invention;
Fig. 2 is schematic side view of the present invention;
In figure: 1, pipe link; 2, suspension hook; 3, sleeve; 4, extension spring; 5, nut; .
Detailed description of the invention
All features disclosed in this specification sheets, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Arbitrary feature disclosed in this specification sheets (comprising any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
A kind of hand-held design buffering suspension hook as depicted in figs. 1 and 2, comprise pipe link 1 and suspension hook 2, sleeve 3 is provided with between described pipe link 1 and suspension hook 2, described suspension hook 2 is symmetricly set on the both sides of sleeve 3, by pinned connection between described suspension hook 2 and sleeve 3, be provided with extension spring 4 between described two suspension hooks 2, described extension spring 4 is symmetricly set on suspension hook 2 tip position, described pipe link 1 is provided with screw thread, below described sleeve 3, is provided with nut 5.
In use, setting nut 5 thus the upper-lower position of regulating sleeve 3 as required, adapts to different environment and uses needs, and extension spring 4 plays buffer action when lifting article to suspension hook 2.
Reasonable in design of the present invention, can be cushioned lifting article by the effect of extension spring, and can the upper-lower height of adjusting lift hook, adapts to the use needs of varying environment, expands Applicable scope, be easy to promote the use of.
The present invention is not limited to aforesaid detailed description of the invention.The present invention expands to any new feature of disclosing in this manual or any combination newly, and the step of the arbitrary new method disclosed or process or any combination newly.
