Abstract
The invention provides a method for changing the appearance of the traditional chain from a round shape or chain shape to a rhombic shape. An anti-cutting chain comprises a chain core and a chain sleeve, wherein the chain sleeve is sleeved outside the chain core; the chain core is in a round structure; the chain sleeve is in a multilateral rhombic structure; the chain core is formed by a plurality of continuous hinged steel wires; and the chain sleeve is in a structure which is formed by connecting a plurality of small chain sleeves together. The chain with the structure can be randomly bent and transformed and can be applicable to different occasions; and meanwhile, the chain with the structure can be firmer when being cut.
Description
Technical field
The present invention relates to a kind of form of structure of chain.
Background technology
The known on the market lockset that chain is arranged all is to adopt circular or chain lock chain structure now; This relatively simple for structure; Cost of production is also lower, the diameter that only need increase chain for the shear resistant that increases chain just can, but this has also brought increase and the increase of cost on the weight; In addition because the development of modern instrument, the lockset of in the past can Chinese People's Anti-Japanese Military and Political College's power cutting hydraulic pressure cut in face of seemed that comparison is fragile.
Summary of the invention
The present invention has proposed a more effective solution in order to solve the deficiency that has known chain now just, when not increasing chain weight, has increased the shear-stable difficulty as far as possible, and the method that the present invention takes is to change the profile that has chain now into a kind of diamond structure by circle or chain strip; It comprises a chain core, and a chain case, chain case are enclosed within outside the chain core; The chain core is a circular configuration, and chain case is polygon diamond structure, and the chain core adopts the continuous multiply steel wire of joining to form; The structure that chain case adopts a plurality of chainlet covers to link together adopts the chain of this structure to be out of shape by free bend, goes for different occasions; Adopt the chain of this structure can be more firm when being sheared simultaneously; Is that demonstration is with cutting circle, chain strip, the state during three kinds of shape metals of rhombus chain sheared respectively energetically like accompanying drawing 1 to accompanying drawing 3; The sectional area of the metal chain of three kinds of shapes in the accompanying drawing is the same; We can see that the edge of a knife when adopting this diamond structure, cut energetically and the contact area of metal are maximum from accompanying drawing 3, thus also maximum of the resistance that receives, in order to cut off the power that metal needs will be bigger; Thereby and the edge of a knife contact area that adopts the chain bar shaped shown in the accompanying drawing 2 with regard to smaller with regard to relatively good shearing, circular locking bar takes second place; Accompanying drawing 4 is that demonstration is cut shearing circle respectively with hydraulic pressure to accompanying drawing 6; The chain bar shaped; State during three kinds of shape metals of rhombus; The sectional area of the metal chain of three kinds of shapes in the accompanying drawing also is the same, and we can see the contact area minimum of the edge of a knife when adopting this chain bar shaped structure, cut energetically and metal from accompanying drawing 5, are cut off the most easily; We can see that the contact area of the edge of a knife and metal chain is a maximum when adopting this rhombus chain structure and from accompanying drawing 6; Anti-shearing effect is best, adopts circular configuration between rhombus and chain bar shaped, so the structure that in face of hydraulic pressure is cut, adopts rhombus will be much better than the chain of circular configuration and chain bar shaped structure aspect anti-shearing.
Beneficial effect of the present invention is: through adopting chain structure of the present invention, when not increasing lockset weight, improved anti-shear ability.

The specific embodiment
At present please in detail referring to these accompanying drawings, combine accompanying drawing that invention is further described down, accompanying drawing 7 is first embodiment of the present invention at present; Fig. 9 is the sectional view of chain, and the method that the present invention takes is to change the profile that has chain now into a kind of diamond structure by circle or chain strip, and it comprises a chain core 101; A chain case 102, chain case 102 are enclosed within outside the chain core 101, and chain core 101 is a circular configuration; Chain case 102 is polygon diamond structure, and chain core 101 adopts the continuous multiply steel wire of joining to form the structure that chain case 102 adopts a plurality of chainlets covers 102 to link together; Adopt the chain of this structure can free bend distortion, go for different occasions, adopt the chain of this structure can be more firm when being sheared simultaneously; Is that demonstration is with cutting circle, chain strip, the state during three kinds of shape metals of rhombus chain sheared respectively energetically like accompanying drawing 1 to accompanying drawing 3; The sectional area of the metal chain of three kinds of shapes in the accompanying drawing is the same; We can see that the edge of a knife when adopting this diamond structure, cut energetically and the contact area of metal are maximum from accompanying drawing 3, thus also maximum of the resistance that receives, in order to cut off the power that metal needs will be bigger; Thereby and the edge of a knife contact area that adopts the chain bar shaped shown in the accompanying drawing 2 with regard to smaller with regard to relatively good shearing, circular locking bar takes second place; Accompanying drawing 4 is that demonstration is cut shearing circle respectively with hydraulic pressure to accompanying drawing 6; The chain bar shaped; State during three kinds of shape metals of rhombus; The sectional area of the metal chain of three kinds of shapes in the accompanying drawing also is the same, and we can see the contact area minimum of the edge of a knife when adopting this chain bar shaped structure, cut energetically and metal from accompanying drawing 5, are cut off the most easily; We can see that the contact area of the edge of a knife and metal chain is a maximum when adopting this rhombus chain structure and from accompanying drawing 6; Anti-shearing effect is best, adopts circular configuration between rhombus and chain bar shaped, so the structure that in face of hydraulic pressure is cut, adopts rhombus will be much better than the chain of circular configuration and chain bar shaped structure aspect anti-shearing.
The those of ordinary skill of technical field also can both understand under the present invention except above-mentioned, can further change the characteristics that are incorporated into shown in the other specific embodiment in any one of this explanation and illustrated each specific embodiment.For example, this diamond structure can be other polyhedron such as 8 shapes, also can the rhomboid ellipsoidal structure of type of being, and the chain core also can adopt similar materials such as nonmetallic material such as nylon in addition.
Though the present invention gives illustrated with regard to its preferred embodiment, the people who is familiar with present technique is understood that, in the spirit and scope of the present invention that in said claims, limited, also can make all changes and change to the present invention.
