Abstract
The utility model relates to a chain with adjustable length, which comprises an H-shaped bracket and chain joint connectors, wherein the two ends of support columns at the two sides of the H-shaped bracket are respectively formed with a concave groove; each chain joint connector consists of a circular arc part, a vertical part and a horizontal bending part; the vertical part of the chain joint connector is inserted into the concave groove of the H-shaped bracket; an end cap respectively penetrates through the vertical part of the chain joint connector and is screwed at the two ends of the support columns at the two sides of the H-shaped bracket; the support columns at the two sides of the H-shaped bracket are respectively screwed with a nut; the nuts comprise a first nut and a second nut; each first nut is positioned in the inner side of each chain joint connector; the plane of bottom end of each first nut is pressed against the horizontal bending part of each chain joint connector; each second nut is positioned at the outer side of each chain joint connector; the plane of top end of each second nut is pressed against the horizontal bending part of each chain joint connector. The chain has the advantages that the chain joint adjusting length of the chain can be adjusted, so the functions of multiple chains various in lengths can be realized by one chain, the use is convenient and rapid, and the resource is saved.
Description
Technical field:
The utility model relates to the technical field of chain, more specifically to a kind of chain of adjustable-length.
Background technique:
Chain consists of the multi-purpose machinery basic part of flexible system rigid member, it is divided into four kinds, Transmitted chains, Conveying chains, pulling chain and Special professional chain, pull chain its be a kind of as pull and lifting chain, and the pulling chain that existing market is generally has more piece chain link to link together, the length of the chain link of the pulling chain of composition is generally fixed.And in actual life, use while acting on the object of long distance with short pulling chain and can not use, during with long pulling chain effect and short-range object, unnecessary chain is relatively in the way, so often need to have the chain of all lengths when making to pull chain, it relatively wastes resource.
Model utility content:
The purpose of this utility model is exactly the deficiency for prior art, and a kind of chain of adjustable-length is provided, and it is simple in structure, easy to use, can regulate length, realizes the function of many chains, has saved resource.
Technology solution of the present utility model is as follows:
A kind of chain of adjustable-length, comprise H type support and link joint, the two ends of H type support two lateral braces form respectively groove, described link joint is comprised of circular arc part, vertical portion and horizontal curved folding part, intert in the groove of H type support the vertical portion of link joint, and end cap is screwed onto respectively the two ends of H type support two lateral braces through the vertical portion of link joint;
On described H type support two lateral braces, be bolted with respectively nut, nut comprises the first nut and the second nut, the first described nut is positioned at the inner side of link joint, the bottom plane of the first nut is pressed against on the horizontal curved folding part of link joint, the second described nut is positioned at the outside of link joint, and the top plane of the second nut is pressed against on the horizontal curved folding part of link joint.
The length of the groove on described H type support is not less than the long end of link joint vertical portion.
On the first described nut and the outer side wall of the second nut, form respectively annular knurl.
The beneficial effects of the utility model are:
1, it can make the chain link of chain regulate length, with a function that realizes many each all length chains, and convenient to use, saved resource.
2, the horizontal kink of the lateral frame on its H type support and link joint can be strengthened the intensity of chain link, prevents chain link lengthening deformation.
Accompanying drawing explanation:
Fig. 1 is the sectional structure schematic diagram of chain link of the present utility model;
Fig. 2 is the structural representation of chain link of the present utility model;
Fig. 3 be chain link of the present utility model change angle structural representation.
In figure: 1, H type support; 2, link joint; 3, end cap; 4, the first nut; 5, the second nut; 11, groove; 21, horizontal curved folding part; 22, vertical portion; 23, circular arc part.
Embodiment:
Embodiment: see shown in Fig. 1 to 3, a kind of chain of adjustable-length, comprise H type support 1 and link joint 2, the two ends of 1 liang of lateral brace of H type support form respectively groove 11, described link joint 2 is comprised of circular arc part 23, vertical portion 22 and horizontal curved folding part 21, intert in the groove 11 of H type support 1 vertical portion 22 of link joint 2, and end cap 3 is screwed onto respectively the two ends of 1 liang of lateral brace of H type support through the vertical portion 22 of link joint 2;
On described 1 liang of lateral brace of H type support, be bolted with respectively nut, nut comprises the first nut 4 and the second nut 5, the first described nut 4 is positioned at the inner side of link joint 2, the bottom plane of the first nut 4 is pressed against on the horizontal curved folding part 21 of link joint 2, the second described nut 5 is positioned at the outside of link joint 2, and the top plane of the second nut 5 is pressed against on the horizontal curved folding part 21 of link joint 2.
The length of the groove 11 on described H type support 1 is not less than the long end of link joint 2 vertical portions 22.
On the first described nut 4 and the outer side wall of the second nut 5, form respectively annular knurl.
Working principle: first end cap 3 and the first nut 4 are interted and bent in link joint 2 processing link joint 2 is front, the end that during assembling, end cap 3 is first tightened in to H type support 1 can not depart from from H type support 1 link joint 2, by rotating the first nut 4 and the second nut 5, make its link joint 2 be fixed on H type support 1, thereby by regulating the first nut 4 and the second nut 5 to control link joint 2, in the position of H type support 1, realize the adjusting of zip length, and a plurality of such chain links are just become to a kind of chain of adjustable-length together.
