Embodiment
At the problem that background technique is mentioned, the utility model embodiment proposes following chain slip-knot, with the flexibility of the chain length adjustment that improves its link and improve the efficient that connects.
Described chain slip-knot comprises:
First connecting end is positioned at an end of chain slip-knot, is used to connect first chain;
Second connecting end is positioned at the other end of chain slip-knot, is used to connect second chain; And the chain cylindrical void, be the through hole between first connecting end and second connecting end, be used to draw the disconnected chain link of first and/or second chain, the distance of the end connecting link of wherein said first chain and the end connecting link of second chain equals zip length.
Wherein disconnected chain link is meant and does not participate in the chain link that connects in the chain that perhaps be called the chain link that does not participate in sprocket wheel-chain transmission, if for example chain is long, then the chain link of excessive portion chain is the chain link that need not to connect.
The chain cylindrical void can have one, is used to draw the disconnected chain link of first and/or second chain, also can have two, is used for drawing respectively the non-link chain link of first and second chain.
First chain and second chain can be same chain, also can be different chains, if on behalf of this chain slip-knot, same chain then this chain is linked end to end.
The purpose that the distance of the end connecting link of above-mentioned requirements first chain and the end connecting link of second chain equals zip length is, the sprocket wheel that guarantees follow-up this chain of cooperation can be smoothly by these two chain links of holding connecting links be connected to form, a plurality of specific embodiments of the chain slip-knot that proposes at the present invention, can there be multiple structure to make the distance of the end connecting link of the end connecting link of the chain of winning and second chain equal zip length, follow-up will specifying in conjunction with the embodiments.
Because above-mentioned chain slip-knot is provided with the chain cylindrical void that is used for drawing the first and/or second disconnected chain link of chain, therefore can be during greater than Len req in chain length, disconnected chain link can be drawn from the chain cylindrical void, reduce the actual chain number that connects, promptly reduce the chain physical length that connects and satisfy actual connection request, and it is too much at disconnected chain link, when needing to increase the chain number of actual connection, can be by reducing the disconnected chain number that the chain cylindrical void is drawn, increase the chain length of actual connection, satisfy actual connection request.Therefore compare the chain length that the chain slip-knot that the utility model embodiment proposes can be regulated its link flexibly with existing chain slip-knot.
In the above-mentioned chain slip-knot, connecting end can connect chain by the disconnected chain link that connects chain, also can connect chain by the end connecting link that connects chain, according to these two kinds of Placements, provide several embodiments of above-mentioned chain slip-knot below, be beneficial to understand the chain slip-knot that the utility model proposes.
Embodiment one, first connecting end is used for connecting described first chain by the disconnected chain link that connects first chain, and second connecting end is used for connecting described second chain by the end connecting link that connects second chain, and its middle-end connecting link is meant the chain link of joint in the chain link of the actual connection of chain.
Fig. 1 is the structural representation of the utility model first embodiment's chain slip-knot, and Fig. 2 is the schematic cross-section during chain slip-knot link chain among the utility model first embodiment, and in conjunction with Fig. 1 and Fig. 2 as can be known, the chain slip-knot 10 that present embodiment proposes comprises:
First connecting end 11 is used for connecting described first chain 20 by the disconnected chain link 21 that connects first chain 20;
Second connecting end 12 is used for connecting described second chain 30 by the end connecting link 31 that connects second chain 30; And
Chain cylindrical void 13 is the through hole between first connecting end 11 and second connecting end 12, is used to draw the whole disconnected chain link of first chain 20, and illustrated whole disconnected chain links comprise disconnected chain link 21 and other disconnected chain link 22.
In the present embodiment, the further concrete structure of chain slip-knot 10 is as follows:
First connecting end 11 is the flat projection, and its size needs can snap in the disconnected chain link 21 of first chain 20, so that snap in disconnected chain link 21 by this flat projection first chain 20 is connected on this chain slip-knot 10;
Second connecting end 12 uses the pin joint structures to connect second chain 30, for example passes end connecting link 31 in second chain 30 by pin 14, and is fixed in and connects second chain 30 in the pin-and-hole 15.
The degree of depth of preferable chain cylindrical void 13 equals positive even numbers times zip length L and deducts the difference that chain link thickness D obtains, this can make that the disconnected chain link in the chain cylindrical void 13 is vertical with connecting link under the chain cylindrical void 13, improve the stability of first chain 20 of first connecting end, 10 connections, and the excessive flatness of first chain 20 and 30 connections of second chain.
For making the distance (referring to the part of Fig. 2 circle mark) of end connecting link of first chain 20 that the end connecting link 31 of second chain is connected with this chain link 31 be zip length L, optionally, the left and right sides width of present embodiment medium chain cylindrical void 13 deducts the distance between pin 14 centers and second chain, the 30 close borders of second connecting end 12 again for zip length L adds a half thickness D of first chain 20.In the distance of the end connecting link of first chain 20 that the end connecting link 31 that guarantees second chain is connected with this chain link 31 (part that marks referring to Fig. 2 circle) is under the condition of zip length L, the left and right sides width of chain cylindrical void 13 can be smaller, but can not be less than the thickness D of first chain 20.
First connecting end is used for connecting described first chain by the disconnected chain link that connects first chain among the embodiment one, and second connecting end is used for connecting described second chain by the end connecting link that connects second chain, in fact, the chain slip-knot that the utility model proposes can also be implemented by following manner:
Embodiment's two, the first connecting ends are used for connecting described first chain by the disconnected chain link that connects first chain, and second connecting end is used for connecting described second chain by the disconnected chain link that connects second chain.
Embodiment three, first connecting end are used for connecting described first chain by the end connecting link that connects first chain, and second connecting end is used for connecting described second chain by the end connecting link that connects second chain.
The concrete structure of chain slip-knot can obtain with reference to embodiment one among embodiment two and the embodiment three, need not to give unnecessary details herein.
The chain slip-knot that the utility model embodiment proposes is provided with the chain cylindrical void, the length that can regulate the chain of actual connection by the disconnected chain link of drawing chain, improved this chain slip-knot link the chain length adjustment flexibility and improve the efficient that connects.
The chain slip-knot that the utility model embodiment proposes can be that pin joint reaches by linkage structures such as projection engagings when connecting chain, need not therefore to guarantee that the width equidimension of chain slip-knot keeps identical with the width of chain.Because the parameter of chain is mainly by the long L of chain link and thickness D and width decision.As long as just can design corresponding chain slip-knot according to different chain link length and widths, thickness, structure is very simple, and cost is very low.These Placements also are easy to loading and unloading in addition, and this has improved the efficient of chain link, and especially for the frequent applicable cases of chain link loading and unloading, this advantage that is easy to load and unload is more outstanding.
