Description
Technical field
This utility model belongs to chain processing technique field, relates to a kind of chain retractable behaviour in the course of processing
The auxiliary body made.
Background technology
Chain is the engineering goods that a kind of versatility is stronger, owing to it has gear and belt concurrently, therefore exists
Transmission, conveying and some special occasions are obtained for and are widely applied.Chain is generally sequentially connected with structure by chain link
Becoming, each chain link is connected and composed by outer plate, inner plate, bearing pin, roller, and outer plate and inner plate are equal
It is provided with through hole and is linked together by bearing pin.
Chain is in the course of processing, it usually needs through steps such as pull force calculation, resisting fatigue detection and prestretching process,
Now, the retractable operation of chain is very frequent, in order to meet above-mentioned existing production needs, and existing offer one side
Case.
Utility model content
The purpose of this utility model is to provide a kind of folding and unfolding chain mechanism for chain.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of folding and unfolding chain mechanism for chain, including base, screw mandrel, disk and winding frame, described screw mandrel
One end is vertically welded on base top；Spring it is arranged with on screw mandrel；Screw mandrel top is fitted with nut, spring

Shape, two are wound around frame is that decussation shape is arranged, and a sprocket wheel is all welded at its two ends, and sprocket wheel is welded and fixed
On disk.
Described base is decussation shape, and it is made up of the steel plate of four right-angled trapezium.
Outside described nut on ring wall relative to position be respectively welded a horizon bar, horizon bar is positioned on bearing
Side.
Relative position, described disk ring side is respectively welded a vertical bar.
The beneficial effects of the utility model: this utility model simple in construction, easy to operate, be suitable to workshop and use,
Utilize nut rotation on screw mandrel, the height of regulation disk；Utilize the resilient support of spring, it is provided that give circle
One elastic anchorage force of dish；Utilize the effect of bearing so that disk drives and is wound around frame rotation retractable chain；
Sprocket wheel can fix one end of chain, convenient winding.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is made further for the ease of it will be appreciated by those skilled in the art that
Bright.
Fig. 1 is the structural representation of a kind of folding and unfolding chain mechanism for chain of this utility model.
Detailed description of the invention
A kind of folding and unfolding chain mechanism for chain, as it is shown in figure 1, include base 1, screw mandrel 2, disk 5 and
It is wound around frame 8；Base 1 is in decussation shape, and it is made up of the steel plate of four right-angled trapezium；Screw mandrel 2 one end
Vertically being welded on base 1 top, screw mandrel 2 is arranged with spring 3, screw mandrel 2 top is fitted with nut 7,
Spring 3 is between base 1 and nut 7；The sheathed bearing 9 that is fixed with, disk 5 on ring wall outside nut 7
Circle centre position is sheathed to be fixed on outside bearing 9 on ring wall, and disk 5 is rotated by bearing 9 opposing nut 7；
The nut 7 upper and lower rotation on screw mandrel 2 for convenience, outside nut 7 on ring wall relative to position
Place is respectively welded a horizon bar 6, and horizon bar is positioned at above bearing 9；
The rotation of disk 5 for convenience, the position relative in disk 5 ring side is respectively welded a vertical bar 4；
Being wound around frame 8 is U-shaped shape, and two are wound around frame 8 and arrange in decussation shape, and its two ends all weld one
Sprocket wheel 10, sprocket wheel 10 is weldingly fixed on disk 5；
This utility model simple in construction, easy to operate, be suitable to workshop and use, utilize nut 7 on screw mandrel 2
Rotate, the height of regulation disk 5；Utilize the resilient support of spring 3, it is provided that prop up to 5 one elasticity of disk
Support force；Utilize the effect of bearing so that disk 5 drives winding frame 8 to rotate retractable chain；Sprocket wheel 10 can
One end of fixing chain, convenient winding.
Above content is only to this utility model structure example and explanation, the skill of affiliated the art
Described specific embodiment is made various amendment or supplements or use similar mode to replace by art personnel
In generation, without departing from the structure of utility model or surmount scope defined in the claims, all should belong to
In protection domain of the present utility model.
