The first clamping plate 4 and the second clamping plate 5 are positioned on the same side of the vertical plate 2 and are buckled with each other from two sides of the first chain ring 100 respectively so as to enclose a channel 6; the channel 6 is communicated with the through hole 3; the first and

second straps

4, 5 both being in contact with the first links 100, may shield the through holes 3 except for the areas that receive the first links 100; and the arrangement direction of the first cardboard 4 and the second cardboard 5 is perpendicular to the central axis of the central hole of the second chain ring 200, and the arrangement direction of the first cardboard 4 and the second cardboard 5 is parallel to the central axis of the central hole of the first chain ring 100; the first link 100 is partially located within the channel 6 and is retained by the channel 6; the height of the channel 6 in the direction perpendicular to the central axis of the central hole of the second link 200 is smaller than the height of the second link 200 in the direction perpendicular to the central axis of the central hole thereof, so that the second link 200 cannot pass through the channel 6 to realize the positioning on the chain positioning device.

The utility model discloses in through correspond the assembly on riser 2 first cardboard 4 with second cardboard 5 to utilize cross connection's structure between two adjacent chain rings, through first cardboard 4 with second cardboard 5 surrounds first chain ring 100 is held to passageway 6 card, and right through-hole 3 shelters from, passageway 6 highly is less than second chain ring 200 along the height of the central axis direction of perpendicular to second chain ring 200's centre bore along the central axis direction of perpendicular to its centre bore, makes second chain ring 200 unable pass through passageway 6 realizes the chain location on the chain positioner.

The following takes the through hole 3 penetrating through the vertical plate 2 in the front-rear direction as an example, to specifically describe the positioning and installation of the chain on the chain positioning device:

as shown in fig. 4, the first chain ring 100 and the second chain ring 200 are both O-shaped closed chain rings, and initially, the first clamping plate 4 and the second clamping plate 5 are both separated from the vertical plate 2, and the chain passes through the through hole 3, so that the chain is distributed on both the front side and the rear side of the vertical plate 2; as shown in fig. 1 to 3 and 5, one of the first links 1001 is partially retained in the through hole 3, and two

second links

2001 and 2002, which are engaged with the first link 1001 and located at the front side and the rear side of the first link 1001, are distributed at the front side and the rear side of the vertical plate 2; moving the first chain ring 1001 so that a gap is formed between the second chain ring 2001 at the front side of the first chain ring 1001 and the vertical plate 2, or a gap is formed between the second chain ring 2002 at the rear side of the first chain ring 1001 and the vertical plate 2; wherein the gap is for fitting the first card 4 and the second card 5. When a gap is formed between the second chain ring 2001 at the front side of the first chain ring 1001 and the vertical plate 2, the first clamping plate 4 and the second clamping plate 5 are fastened to each other from the front side of the vertical plate 2 and from two opposite sides of the first chain ring 1001 respectively, so that the first chain ring 1001 enters the channel 6 surrounded by the first clamping plate 4 and the second clamping plate 5, and then the first clamping plate 4 and the second clamping plate 5 are fixed on the vertical plate 2. The first clamping plate 4 and the second clamping plate 5 are positioned between the vertical plate 2 and the second chain ring 2001 at the front side of the first chain ring 1001, the through holes 3 except for the area communicated with the channel 6 are shielded by the first clamping plate 4 and the second clamping plate 5, the volume of the channel 6 is smaller than that of the second chain ring 200, and then the second chain ring 2001 at the front side of the first chain ring 1001 is limited at the front side of the vertical plate 2 by the first clamping plate 4 and the second clamping plate 5 and cannot move towards the rear side of the vertical plate 2; the second chain ring 2002 on the rear side of the first chain ring 1001 is also limited by the first clamping plate 4 and the second clamping plate 5, and cannot move to the front side of the vertical plate 2, so that the chain is positioned on the chain positioning device.

Similarly, when the chain passes through the through hole 3 and the first chain ring 1001 is moved to the position in the through hole 3, the gap can be reserved between the second chain ring 2002 on the rear side of the first chain ring 1001 and the vertical plate 2, and then the first clamping plate 4 and the second clamping plate 5 are assembled on the rear side of the vertical plate 2. The utility model discloses in to the chain be in location assembly on the chain positioner both avoids the complexity of chain location operation, can promote the stability of chain location again, avoids the chain to follow chain positioner is gone up the pine and is taken off, and produces the potential safety hazard.

In the utility model, when the chain needs to be disassembled, the first clamping plate 4 and the second clamping plate 5 are detached from the vertical plate 2, and the chain is pulled to separate from the through hole 3; the utility model discloses in chain positioner need not to twine the chain, the location that the chain can be realized to the welding, is convenient for lift the chain off again.

The thickness of the first card 4 is less than the maximum distance between two adjacent second links 200; further, the sum of the thicknesses of the first clamping plate 4 and the vertical plate 2 is smaller than the maximum distance between two adjacent second chain rings 200, so that when the first clamping plate 4 and the second clamping plate 5 limit the first chain rings 100, the vertical plate 2, the first clamping plate 4 and the second clamping plate 5 can be located between two adjacent second chain rings 200, the displacement of the chain which can move relative to the chain positioning device after the chain is positioned on the chain positioning device is reduced, the chain is locked as much as possible, and the chain is prevented from shaking.
