Abstract
The invention discloses a transmission chain with an expansion device. The transmission chain with the expansion device comprises a chain which consists of chain rings, and an expander is separably arranged on the chain in a clamping and combining manner. The transmission chain with the expansion device, disclosed by the invention, utilizes the expander which is integrally formed from ABS engineering plastics. Users can clamp and combine the expander to the local part of the chain as needed, and through the pulling force of the expander, the rigidity of the chain is changed, so that the chain is thoroughly prevented from being piled and wound locally. The expander is simple in structure and convenient to use.
Description
Technical field
The present invention relates to a kind of building hoisting apparatus, or rather, is a kind of transmission chain with extension fixture.

At building field, can often use chain as transmission device, flexibly connect because chain is socketed to form by chain circle and is formed, easily there is heap superimposition and be wound around in the local of chain, even can block hoist crane, affect normal hoisting operation.
Summary of the invention
The present invention mainly solves the technical problem existing for prior art, thus provides a kind of transmission chain with extension fixture.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
With a transmission chain for extension fixture, the transmission chain of described band extension fixture comprises a chain be made up of chain circle, and on described chain, engaging has an expander separably.
As preferred embodiment of the present invention, described expander comprises the supportive body of an elongated strip, one end of described supportive body is provided with one first engaging and gives prominence to one second engaging outstanding, the direction of extension and described second that the first described engaging is given prominence to engages outstanding contrary, the other end of described supportive body is provided with one first engaging circular arc and one second engaging circular arc, it is contrary that described the first engaging circular arc direction of extension and second engages circular arc, the direction of extension that described first engaging is given prominence to is identical with the first engaging circular arc, the direction of extension that the second described engaging is given prominence to is identical with the second engaging circular arc.
As preferred embodiment of the present invention, described second engaging is outstanding to be greater than described first with the second distance engage between circular arc and to engage the distance of giving prominence to and to engage with described first between circular arc.
As preferred embodiment of the present invention, described supportive body, the first engaging is outstanding, the second engaging is outstanding, the first engaging circular arc and the second engaging circular arc are that ABS engineering plastics are one-body molded.
As preferred embodiment of the present invention, one end of described supportive body is provided with an anticreep hole.
The transmission chain of band extension fixture of the present invention utilizes the integrated expander of ABS engineering plastics, this expander can be fastened on the local passing chain by user as required, change lock chain rigidity by the tension force of expander, thoroughly prevent the heap superimposition of the local of chain to be wound around.This expander structure is simple, easy to use.

Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
The invention provides a kind of transmission chain with extension fixture.
As shown in Figures 1 to 5, the transmission chain of band extension fixture of the present invention comprises a chain be made up of chain circle 21 2, and on this chain 2, engaging has an expander 1 separably.
This expander 1 comprises the supportive body 11 of an elongated strip, one end of this supportive body 11 is provided with one first engaging outstanding 12 and one second engaging outstanding 13, the direction of extension of this first engaging outstanding 12 with this second engage give prominence to 13 contrary, the other end of this supportive body 11 is provided with one first engaging circular arc 14 and one second engaging circular arc 15, it is contrary that this first engaging circular arc 14 direction of extension and second engages circular arc 15, the direction of extension of this first engaging outstanding 12 is identical with the first engaging circular arc 14, and the direction of extension of this second engaging outstanding 13 is identical with the second engaging circular arc 15.
This second engaging outstanding 13 and the second distance engage between circular arc 15 are greater than this and first engage and give prominence to 12 and first engage distance between circular arc 14 with this.
Outstanding 13, the first engaging circular arc 14 of outstanding 12, second engaging of this supportive body 11, first engaging and the second engaging circular arc 15 are that ABS engineering plastics are one-body molded.
One end of this supportive body 11 is provided with an anticreep hole 16.
The transmission chain of the band extension fixture of this invention utilizes the integrated expander of ABS engineering plastics, this expander can be fastened on the local passing chain by user as required, change lock chain rigidity by the tension force of expander, thoroughly prevent the heap superimposition of the local of chain to be wound around.This expander structure is simple, easy to use.
Below only in one embodiment mentality of designing of the present invention is described, when system allows, the present invention can expand to external more function module simultaneously, thus expands its function to greatest extent.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
