Description
Technical field
The utility model belongs to field of chains, and in particular, it relates to a kind of length-adjustable assembling chain link.
Background technique
Chain is made up of chain link, when needing to increase the length of chain, because chain link forms by a metal bar is bending, the head and the tail place of connecing of metal bar can produce a gap, increase the gap on chain link, chain link just can be made to be connected with another chain link by gap, and then in reduction gap, placement chain link is crossed gap with chain link and is separated, while the size changing gap, likely can cause damage to chain link, also add operational difficulty, so improved existing chain link.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of length by regulating link length to play adjusting chain.
For achieving the above object, the utility model provides following technological scheme: comprise chain link body, and described chain link body is made up of the first U-shaped ring and the second U-shaped ring, and described first U-shaped ring and the second U-shaped ring connecting end surface are provided with Liang Zu bindiny mechanism; Described bindiny mechanism comprises fixing rod, slide bar and swingle; Described fixing rod is arranged with slide bar, and one end of described fixing rod is fixedly connected with the first U-shaped ring, and described slide bar is provided with outside thread; Described fixing rod is axially arranged with raised line with slide bar surface of contact, and described slide bar is provided with the chute that to match with raised line, and described slide bar is connected with fixing rod slippage; Described jack rod sleeve is provided with swingle, and described swingle is provided with the internal thread matched with slide bar outside thread, and one end of described slide bar is connected with the second U-shaped ring; Described fixing rod is provided with annular groove near the side of the first U-shaped ring, and described swingle is provided with the projection matched with annular groove.
By adopting technique scheme, when needing the size regulating chain link, rotate swingle, fixing rod keeps static relative to swingle, fixing rod is provided with raised line vertically, the chute of slide bar matches with the raised line on fixing rod, chute limits raised line and rotates, raised line can only move vertically in chute, due to the spacing axial motion of swingle of the projection on swingle, swingle can only rotate around annular groove, therefore swingle position keeps motionless, swingle rotates, internal thread has the trend driving outside thread to rotate, because swingle relative position keeps motionless, slide bar can not rotate, can only axial motion in chute, slide bar can be made to move, the distance between the U-shaped ring of adjustment second and the first U-shaped ring can be played, the length of chain changes.
The utility model is set to further: described slide bar is provided with limiting stopper near one end of the first U-shaped ring, described limiting stopper is provided with the outside thread matched with swingle internal thread, and described swingle is provided with away from one end of the first U-shaped ring the fixed hole matched with slide bar.
By adopting technique scheme, when rotating rotary rods makes slide bar slippage, limiting stopper can effectively prevent slide bar from departing from the chute of fixing rod, and slide bar is moved by fixed hole, time arrival limiting stopper contacts with fixed hole, motion terminates, so when rotating swingle and extending lifting, can relieved rotation swingle courageously, need not worry that transition is rotated, slide bar is separated with swingle, causes the inconvenience in use.
The utility model is set to further: described swingle is provided with the fixed block preventing swingle from rotating.
By adopting technique scheme, the preferred hand tighten screw of fixed block, swingle arranges tapped hole, by hand tighten screw is screwed in tapped hole, fixed block is conflicted with fixing rod be connected, swingle and fixing rod are fixed, thus stop slide bar to shrink under stressed effect, driven rotary bar rotates, thus effectively improves the stability that bindiny mechanism is fixed on a certain position.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of length-adjustable assembling chain link of the utility model;
Fig. 2 is the A portion schematic diagram of Fig. 1.
In figure: 1, the first U-shaped ring; 2, the second U-shaped ring; 3, fixing rod; 4, slide bar; 5, swingle; 6, raised line; 7, chute; 8, annular groove; 9, protruding; 10, limiting stopper; 11, fixed hole; 12, fixed block.
Embodiment
Shown in Fig. 2, the one length-adjustable assembling chain link structure that present case is implemented, comprise chain link body, described chain link body is made up of the first U-shaped ring 1 and the second U-shaped ring 2, it is characterized in that: described first U-shaped ring 1 and the second U-shaped ring 2 connecting end surface are provided with Liang Zu bindiny mechanism; Described bindiny mechanism comprises fixing rod 3, slide bar 4 and swingle 5; Described fixing rod 3 is arranged with slide bar 4, and one end of described fixing rod 3 is fixedly connected with the first U-shaped ring 1, and described slide bar 4 is provided with outside thread; Described fixing rod 3 is axially arranged with raised line 6 with slide bar 4 surface of contact, and described slide bar 4 is provided with the chute 7 that to match with raised line 6, and described slide bar 4 is connected with fixing rod 3 slippage; Described slide bar 4 is arranged with swingle 5, and described swingle 5 is provided with the internal thread matched with slide bar 4 outside thread, and one end of described slide bar is connected with the second U-shaped ring 2; Described fixing rod 3 is provided with annular groove 8 near the side of the first U-shaped ring 1, and described swingle 5 is provided with the projection 9 matched with annular groove 8;
